Description

Heating, ventilation and/or air conditioning device and motor vehicle

Technical Field

The present invention relates to the field of heating, ventilation and/or air conditioning devices, and more particularly to a heating, ventilation and/or air conditioning device and a motor vehicle.

Background

With the widespread use of heating, ventilation and/or air conditioning units in the domestic and commercial sector, there is also a growing demand for heating, ventilation and/or air conditioning units, in particular for motor vehicles.

In motor vehicles, on the one hand, heating, ventilation and/or air conditioning systems are generally not or only simply provided with a layered structure. However, the fact that no layered structure is arranged leads to that only single air flow of internal circulation air or fresh air enters the air conditioning device, and different air flow types can not be adopted for blowing face and blowing feet; although the simple layered structure can realize layered entry of fresh air and internal circulation air in the air conditioner, the air flow space separation of the layered air flows in the housing is not clear, the flow paths of the layered air flows are mixed, the air flows cannot be well guided to the corresponding outlets, and the air temperature output by each outlet is difficult to be independently regulated and controlled. On the other hand, considering that the heating, ventilation and/or air conditioning apparatus is to be installed under the dashboard of the vehicle, current heating, ventilation and/or air conditioning apparatuses generally have a large vertical solid volume, which after installation will cause the dashboard to rise, greatly limiting the visibility of the driver.

Accordingly, there is a need for a heating, ventilation and/or air conditioning apparatus that enables layered intake of different airflows while achieving good heating, ventilation and/or air conditioning functions, and that is capable of well separating the flow space of each layered airflow by cooperation of structural members within a housing, and that enables the air temperature output from each outlet to be independently regulated and controlled, and that has an ultra-thin design, particularly with a small volume in the Z-direction (vertical) direction, as desired.

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are also within the scope of the invention.

As used in this application and in the claims, the terms "a," "an," "the," and/or "the" are not specific to the singular, but may include the plural, unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that the steps and elements are explicitly identified, and they do not constitute an exclusive list, as other steps or elements may be included in a method or apparatus.

The modules are merely illustrative, and different aspects of the systems and methods may use different modules.

Flowcharts are used in this application to describe the operations performed by systems according to embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in order precisely. Rather, the various steps may be processed in reverse order or simultaneously, as desired. Also, other operations may be added to or removed from these processes.

Fig. 1 illustrates a perspective view of a heating, ventilation and/or air conditioning apparatus 100 according to an embodiment of the present invention, fig. 2 illustrates a top view of the heating, ventilation and/or air conditioning apparatus 100 according to an embodiment of the present disclosure, and fig. 3 illustrates a cross-sectional view of the heating, ventilation and/or air conditioning apparatus 100 according to a center axis Oy in fig. 2.

Referring to fig. 1 and 2 in combination, for example, the heating, ventilation and/or air conditioning apparatus 100 includes a housing 110, the housing 110 permitting airflow therethrough and having a first outlet 160, a second outlet 180 and a dividing wall 150 (the dividing wall 150 is shown in fig. 6). And the heating, ventilation and/or air conditioning device has a center axis Oy, for example (in the example shown in fig. 1, the heating, ventilation and/or air conditioning device is symmetrical with respect to the center axis Oy, for example).

For example, referring to fig. 2 and 3, the first outlet 160 may be a foot outlet, and the foot outlet may further include a forefoot outlet 161 and a rearfoot outlet 162, for example, and an opening center line of the rearfoot outlet 162 is, for example, an A-A line. It should be appreciated that embodiments of the present disclosure are not limited by the specific number of first outlets.

The second outlet 180 may be a vent outlet or a demister outlet. Embodiments of the present disclosure are not limited by the specific number of second outlets and the type thereof.

The layered partition wall 150 refers to a wall-like structure for layering the air flow in the housing, and may include, for example, a plurality of sub-partition walls for achieving layering of the air flow.

Specifically, referring to fig. 3, the layered partition 150 includes, for example, a first partition 151. The first partition wall 151 has a first partition portion 1511, and the first partition portion 1511 partitions the first space V1 and the second space V2 in the housing 110.

As shown in fig. 3, for example, the through opening formed inside the housing via the first partition wall is to be engaged with the corresponding damper, and the first partition wall may include a plurality of partitions, for example, a first partition portion, a second partition portion, and the like, as needed.

It should be understood that the first space V1 and the second space V2 refer to two subspaces within a housing partitioned via the first partition wall. The first space V1 is schematically shown in a lower left, upper right and gray slope line and the second space V2 is schematically shown in a lower left, upper right and black slope line in fig. 3.

The heating, ventilation and/or air conditioning device 100 further includes a first damper 170, the first damper 170 being disposed within the housing 110, and the first damper 170 being operable in a first position and a second position.

The first damper is, for example, a flap damper, which is rotatable about its own rotation axis between two extreme positions, and the first and second positions are, for example, the two extreme positions of the first damper 170, namely a fully open position and a fully closed position. Specifically, the first position is, for example, a fully open position of the first damper, such as a position where the first damper is fully open to abut against the first dividing wall 151 (as shown in fig. 3). The second position is, for example, a fully closed position, i.e., a position in which the first damper abuts against the housing interior structure and the opening corresponding to the first damper is fully closed.

The operable first position and second position means that the opening position of the first damper may be adjusted according to the actual situation, for example, the position of the first damper may be adjusted by controlling the rotation direction and position of a rotating motor connected to the first damper, or the position of the first damper may be adjusted by other means, so that the first position or the second position may be set according to the actual requirement. It should be appreciated that embodiments of the present disclosure are not limited by the particular manner in which the first damper opening position is adjusted.

Referring to fig. 3, when the first damper 170 is in the first position, the first damper 170 is engaged with the first partition 1511 to guide the air flow in the second space V2 to flow out through the second outlet 180 and to guide the air flow in the first space V1 to flow out through the first outlet 160.

Fig. 4 shows a sectional view of the heating, ventilation and/or air conditioning device 100 according to the center axis Oy in fig. 2, wherein the first damper is in the second position (fully closed position). Referring to fig. 4, when the first damper 170 is in the second position, the first damper 170 closes the first outlet 160 such that both the air flow in the first space V1 and the air flow in the second space V2 flow out of the second outlet 180.

Based on the above, in the present application, on the basis of realizing a good heating, ventilation and/or air conditioning function, a layered partition wall is provided in the heating, ventilation and/or air conditioning device, by which the first partition portion of the first partition wall separates the first space V1 and the second space V2 in the housing, and by the cooperation of the first partition portion and the first damper, when the first damper is in the first position, the first damper is engaged with the first partition portion to guide the air flow in the second space V2 to flow out through the second outlet, and guide the air flow in the first space V1 to flow out through the first outlet, so that by reasonable planning setting of structural components in the housing, the first damper is multiplexed to participate in the separation and guide of the air flow space, so that two air flow spaces for different air flows can be well separated out through the flexible cooperation of the first partition portion and the first damper component, and the air flow in different air flow spaces is guided to be output through different outlets, thereby being beneficial to realizing a plurality of modes of air flows in the flexible layout and/or each of the air conditioning device according to actual needs.

Fig. 5 shows a cross-sectional view of the heating, ventilation and/or air conditioning unit 100 according to the center axis Oy in fig. 2, wherein the first and second mixing dampers are in a fully open position. Fig. 6 shows a cross-sectional view of the heating, ventilation and/or air conditioning unit 100 according to the center axis Oy in fig. 2, wherein the first and second mixing dampers are in a fully closed position.

In some embodiments, referring to fig. 5, the heating, ventilation, and/or air conditioning apparatus 100 further includes a first airflow handling unit 130, a first mixing damper 310, and/or a second mixing damper 320.

Referring to fig. 5, the first air flow processing unit 130 is disposed within the housing 110 and upstream of the first dividing wall 151. It should be appreciated that upstream and downstream are defined herein along the flow direction of the intake air flow.

It should be appreciated that the first air flow processing unit 130 may be, for example, a heater, such as a PTC heater, according to actual needs.

The first mixing damper 310 refers to a damper component for adjusting the temperature of the air flow entering the first space V1; the second mixing damper 320 refers to a damper component for adjusting the temperature of the air flow entering the second space V2. As shown in fig. 5, the first and second mixing dampers may be disposed downstream of the first and second air flow processing units 130 in the flow direction of the intake air flow, and upstream of the first and second spaces V1 and V2, respectively, to achieve adjustment of the air flow temperatures in the first and second spaces by controlling the ratio of the air flow passing through and bypassing the first air flow processing units 130.

It should be appreciated that the first and second mixing damper may be, for example, the same type of damper components of the same size, or different types or sizes of damper components may be selected as desired. Embodiments of the present disclosure are not limited by the type relationships and size relationships of the first and second blend doors.

For example, the first and second blend doors may each be a sliding door as shown in fig. 5 with the sliding flap thereof being operable to slide in two opposite directions about its sliding central axis to control the opening position of the sliding door. And the first and second blend doors each have, for example, two extreme positions: a fully open position and a fully closed position, and the first and second mixing dampers are movable between the fully open and fully closed positions.

Referring to fig. 3 and 5 in combination, the first partition 151 further includes, for example, a second partition 1512. The second partition 1512 partitions the third space V3 and the fourth space V4 in the housing 110. Wherein a part of the air flow passing through the first air flow processing unit 130 enters the third space V3, and another part enters the fourth space V4. The third space V3 is schematically shown with black particle filling in fig. 5, and the fourth space V4 is schematically shown with vertical line filling.

It should be appreciated that the third space and the fourth space are only intended to illustrate two different gas flow spaces divided by the second partition of the first partition wall, and are not intended to be limiting thereof.

Wherein the first mixing damper 310 separates the third space V3 from the first space V1 when in the fully opened position. The second mixing damper 320 separates the fourth space V4 from the second space V2 when in the fully opened position.

Specifically, the fully open position of the first mixing damper 310 refers to, for example, the first mixing damper being in a position that cooperates with the second divider to achieve a first and third spatial separation, for example, the first mixing damper 310 sliding in a first direction to an extreme position and engaging the second divider 1512 (as shown in fig. 5). For example, referring to fig. 5, when the first mixing damper 310 is in the fully opened position, one end of the first mixing damper 310 is coupled to the second partition 1512, and the other end is coupled to the inner wall of the housing, and at this time, the second partition 1512, the first mixing damper 310, and the inner wall of the housing cooperate together to partition the third space V3 from the first space V1.

For example, in this case, as shown in fig. 5, for the stratified air flow corresponding to the first mixing damper, the air flow flowing through the first air flow processing unit 130 in the stratified air flow will not enter the first space V1 due to the obstruction of the first mixing damper 310, i.e., only a portion of the stratified air flow not flowing through the first air flow processing unit 130 in the stratified air flow corresponding to the first mixing damper can enter the first space (i.e., can be output through the corresponding outlet later).

The fully closed position of the first mixing damper 310 refers, for example, to a position (as shown in fig. 6) in which the first mixing damper 310 slides to a limit in a second direction substantially opposite to the first direction, at which point the first mixing damper is in a position that cooperates with the inner wall of the housing to achieve separation of the first space from a fifth space described below. In this case, as shown in fig. 6, for the stratified air flow corresponding to the first mixing damper, the air flow of the stratified air flow that does not flow through the first air flow processing unit 130 will not enter the first space V1 due to the obstruction of the first mixing damper 310, i.e., only a portion of the air flow of the stratified air flow that flows through the first air flow processing unit 130 can enter the first space (i.e., can be subsequently output through the corresponding outlet) for the stratified air flow corresponding to the first mixing damper.

The fully opened position of the second mixing damper 320 refers to a position in which the second mixing damper 320 slides in the third direction to an extreme position and engages the second divider 1512 (as shown in fig. 5). For example, referring to fig. 5, when the second mixing damper 320 is in the fully opened position, one end of the second mixing damper 320 is coupled to the second partition 1512, and the other end is coupled to the inner wall of the housing, and at this time, the second partition 1512, the second mixing damper 320, and the inner wall of the housing cooperate together to partition the fourth space V4 from the second space V2.

For example, in this case, as shown in fig. 5, for the stratified air flow corresponding to the second mixing damper, the air flow flowing through the second air flow processing unit 130 of the stratified air flows will not enter the second space V2 due to the obstruction of the second mixing damper 320, i.e., only a portion of the stratified air flow not flowing through the first air flow processing unit 130 of the stratified air flows corresponding to the second mixing damper can enter the second space (i.e., can be output through the corresponding outlet).

The fully closed position of the second mixing damper 310 refers to the position in which the second mixing damper 320 slides to the limit in a fourth direction generally opposite the third direction (as shown in fig. 6). The second mixing damper is now in a position to cooperate with the inner wall of the housing to effect separation of the second space from a sixth space described below. In this case, as shown in fig. 6, for the stratified air flow corresponding to the second mixing damper, the air flow of the stratified air flow that does not flow through the first air flow processing unit 130 will not enter the second space V2 due to the obstruction of the second mixing damper 320, i.e., only a portion of the air flow of the stratified air flow that flows through the first air flow processing unit 130 can enter the second space (i.e., can be subsequently output through the corresponding outlet) for the stratified air flow corresponding to the second mixing damper.

For example, the first mixing damper may be disposed in a flow path of an upper air stream in the stratified air stream to effect temperature adjustment of the upper air stream in the stratified air stream, and the second mixing damper may be disposed in a flow path of a lower air stream in the stratified air stream to effect temperature adjustment of the lower air stream.

It should be appreciated that while the above description focuses on two extreme positions of the first and second blend doors, the first and second blend doors may be in any intermediate position between the fully open and fully closed positions (as shown in fig. 3) as desired, in which the manner of air circulation will be described in more detail below in connection with the functional modes of heating, ventilation and/or air conditioning.

Based on the above, in the present application, by providing that the housing includes the first and second mixing damper and the first air flow processing unit (e.g., heater), the temperature of the air flow entering the first space can be adjusted by the opening position of the first mixing damper according to actual needs; the temperature of the air flow entering the second space is regulated by the opening position of the second air mixing door, so that the independent regulation of different air flow temperatures after layering is realized. And a third space and a fourth space are separated in the shell through a second separation part, and the third space is separated from the first space when the first air mixing door is in a completely closed position; when the second mixing damper is in the fully closed position, the fourth space is separated from the second space, so that the first mixing damper and the second mixing damper can be reused as a spacer between adjacent spaces, thereby optimizing the structural layout in the housing.

Referring to fig. 6, in some embodiments, the layered partition 150 also has a second partition 152.

The second partition wall 152 is located upstream of the first air flow processing unit 130, and the second partition wall 152 partitions the fifth space V5 and the sixth space V6 within the housing 110.

For example, referring to fig. 6, the second partition wall starts from the lower surface (e.g., at the midpoint of the lower surface) of the first airflow treatment unit 130 and extends, for example, to the respective inner wall of the housing or engages with other components within the housing, such as in fig. 6, for example, engages with the inner surface of a second airflow treatment unit (e.g., an evaporator) to separate the fifth space and the sixth space.

And wherein a part of the air flow passing through the first air flow processing unit 130 is from the fifth space V5 and another part is from the sixth space V6.

And wherein the fifth space V5 is separated from the first space V1 when the first mixing damper 310 is in the fully closed position; the second mixing damper 320 separates the sixth space V6 from the second space V2 when in the fully closed position.

For example, referring to fig. 6, when the first mixing damper is in the fully closed position as previously described, both ends of the first mixing damper are engaged with the corresponding inner wall of the housing, and at this time, the corresponding inner wall of the housing, the first mixing damper, and the second partition wall cooperate to separate the fifth space V5 from the first space V1. And further referring to fig. 6, when the second mixing damper is in the fully closed position as previously described, the two ends of the second mixing damper are also engaged with the corresponding inner wall of the housing, at which time the corresponding inner wall of the housing, the second mixing damper and the second partition cooperate to separate the sixth space V6 from the second space V2.

Based on the above, in the present application, by providing the layered partition wall further with the second partition wall, the fifth space and the sixth space are further divided upstream of the first airflow processing unit by the second partition wall, so that corresponding different airflow spaces can be provided for different layered airflows upstream of the first airflow processing unit, thereby providing good layered airflow spaces on both upstream and downstream of the first airflow processing unit; and isolating the fifth space from the first space by providing the first mixing damper in the fully closed position; the sixth space is separated from the second space when the second mixing air door is in the completely closed position, so that the first mixing air door and the second mixing air door can be reused to the greatest extent to realize separation and communication of the spaces according to actual needs, the air flow path is flexibly selected and set, the air flow direction is guided, and the device can realize multiple working modes.

In some embodiments, the heating, ventilation and/or air conditioning apparatus 100 further includes a second airflow treatment unit 120.

The second air flow treatment unit may be, for example, a heat exchanger. Specifically, for example, an evaporator in a cooling mode and a condenser in a heat pump mode.

Referring to fig. 6, the second air flow treatment unit 120 is disposed within the housing 110 and upstream of the second partition wall 152.

For example, referring to fig. 6, the second air flow treatment unit may be positioned, for example, near the inlet of the heating, ventilation and/or air conditioning apparatus, through which air flow entering the housing will first pass.

For example, one end of the second partition wall is joined to the lower surface of the first air flow processing unit, and the other end of the second partition wall is joined to the inner side surface (which faces the inside of the housing) of the second air flow processing unit.

Wherein a part of the air flow passing through the second air flow processing unit 120 enters the fifth space V5 and another part enters the sixth space V6.

Based on the above, by providing the heating, ventilating and/or air conditioning apparatus 100 further including the second air flow processing unit 120 and further providing the second air flow processing unit upstream of the second partition wall, the layered air flow entering the heating, ventilating and/or air conditioning apparatus 100 may be firstly subjected to air flow processing (for example, processing via an evaporator) via the second air flow processing unit, then respectively enter the fifth space V5 and the sixth space V6, and then be further subjected to processing (for example, heating processing via a heater) via the first air flow processing unit according to actual needs, thereby being beneficial to performing multi-level processing on the intake air flow according to actual needs, so as to achieve good heating, ventilating and/or air conditioning effects.

In some embodiments, the first outlet 160 is a blowing foot outlet. And at this time, the air flow outputted through the first outlet is, for example, internal circulation air.

In the present application, by setting the first outlet as the blowing pin outlet, the first air inlet airflow (for example, the upper air inlet airflow) of the plurality of air inlet airflows entering in a layered manner can be output completely through the blowing pin outlet under the condition that the blowing pin outlet is opened through the air flow path formed by the second air flow processing unit, the fifth space and/or the third space and the first space. In particular, when the first air flow is the internal circulation air, the foot blowing operation can be performed via the internal circulation air while ventilation defogging is performed using the fresh air via the layered partition wall.

In some embodiments, the second outlet 180 includes at least one of a vent outlet, a demisting outlet. And at this time, the air flow outputted through the second outlet is, for example, fresh air.

In the application, by setting the second outlet as at least one of the ventilation outlet and the demisting outlet, when the input stratified air flow is the internal circulation air and the fresh air, the internal circulation air can be used as the first air inlet air flow (for example, the upper air inlet air flow) through the cooperation of the first air door and the stratified partition wall, and the stratified air flow is output from the foot blowing outlet under the guidance of the first air door through the air flow flowing paths formed by the second air flow processing unit, the fifth space and/or the third space and the first space; fresh air can also be used as a second inlet air flow (for example, lower inlet air flow), and the fresh air is output through a second outlet under the guidance of a first air door through an air flow path formed by the second processing unit, the sixth space and/or the fourth space and the second space, so that functions of ventilation, defogging and the like are realized.

In some embodiments, referring to fig. 6, the second air flow treatment unit 120 is arranged in a substantially orthogonal manner to the first air flow treatment unit 130. For example, the first air flow processing unit 130 is arranged substantially horizontally with respect to the vehicle in the installed state, and the second air flow processing unit 120 is arranged substantially vertically with respect to the vehicle in the installed state.

Based on the above, by arranging the second air flow treatment unit 120 and the first air flow treatment unit 130 in a substantially orthogonal manner in the present application, compared with the parallel arrangement of the first and second air flow treatment units (such as the parallel arrangement that the first and second air flow treatment units are vertically arranged or horizontally arranged or obliquely arranged at the same angle), the three-dimensional volume of the heating, ventilating and/or air conditioning device in the Z-direction (vertical) direction can be reduced, on the one hand, by adopting the orthogonal arrangement of the first and second air flow treatment units in the present application; on the other hand, by arranging the vertical layout of the first air flow processing unit and the second air flow processing unit, the internal space of the shell can be better improved under the layout, and the arrangement of the layering partition walls and the formation of the air flow spaces corresponding to different layering air flows are facilitated, namely, the optimization of the internal structure of the shell and the realization of better layering air flow flowing and guiding are facilitated based on the vertical layout.

In some embodiments, the first outlet 160 is located above the second airflow treatment unit 120.

By providing the first outlet 160 above the second air flow treatment unit 120, it is possible to optimize the structural layout of the heating, ventilation and/or air conditioning device and to facilitate a better output of air flow via the first outlet (e.g. the blowing foot outlet) after the heating, ventilation and/or air conditioning device is mounted on the dashboard of the motor vehicle.

In some embodiments, referring to fig. 2, the heating, ventilation and/or air conditioning device 100 further includes a central dividing wall 141, the central dividing wall 141 dividing the housing into a left half 112 and a right half 113.

For example, in fig. 2, a right half of the foot-blowing opening 160 is shown, which includes a front foot-blowing outlet, a rear foot-blowing outlet, and in conjunction with the corresponding cross-sectional views of the right half of the housing shown in fig. 7-11, the right half housing also includes, for example, a front vent outlet, a rear vent outlet, a defogging outlet. Correspondingly, the left half of the housing has, for example, a front ventilation outlet, a rear ventilation outlet, a defogging outlet, a front blowing foot outlet, a rear blowing foot outlet, respectively, and a layered dividing wall, a first air flow treatment unit and a second air flow treatment unit, respectively.

For example, after the heating, ventilation and/or air conditioning device 100 is installed in a motor vehicle, the left half 113 is configured to provide a corresponding heating, ventilation and/or air conditioning function to the right side (passenger side) of the motor vehicle, for example, and can flexibly switch among a foot-blowing ventilation dual mode, a foot-blowing defogging dual mode, a defogging mode, a foot-blowing mode, and a ventilation mode. And after the heating, ventilation and/or air conditioning apparatus 100 is installed in a motor vehicle, the right half 114 is configured to provide a corresponding heating, ventilation and/or air conditioning function to the left side (driver side) of the motor vehicle, for example, and can flexibly switch among a foot-blowing ventilation dual mode, a foot-blowing defogging dual mode, a defogging mode, a foot-blowing mode, and a ventilation mode.

It will be appreciated that the above description is given of only one exemplary manner of operation of the left and right halves, and that the left half 112 may be configured to provide corresponding heating, ventilation and/or air conditioning functions to the left side (driver side) of the motor vehicle and the right half 113 to provide corresponding heating, ventilation and/or air conditioning functions to the right side (passenger side) of the motor vehicle, as desired.

Based on the above, in the present application, the case is divided into the left half and the right half by providing the central partition wall, so that the heating, ventilating and/or air conditioning apparatus 100 is further divided into the left and right by the central partition wall on the basis of the separate temperature control of the separate air flows as described above, and the left half and the right half can be independently controlled, so that the left half and the right half can be independently configured in the foot-blowing ventilating dual mode, the foot-blowing defogging dual mode, the defogging mode, the foot-blowing mode, the ventilation mode, so that different heating, ventilating and/or air conditioning functions can be provided to the right side (passenger side) and the left side (driver side) of the motor vehicle, and the design of the dual zones in the heating, ventilating and/or air conditioning apparatus is realized.

The airflow path and corresponding modes of operation of the heating, ventilation and/or air conditioning apparatus 100 described above will be described in more detail below in connection with specific embodiments. The heating, ventilating and/or air conditioning apparatus 100 may be, for example, a two-layer, two-zone heating, ventilating and/or air conditioning apparatus, i.e., the heating, ventilating and/or air conditioning apparatus 100 may be capable of separately introducing an intake air flow (which may be, for example, the same air flow type or different air flow types) into an upper air flow inlet and a lower air flow inlet, so as to divide the upper air flow and the lower air flow into relatively independent air flow paths and channels. In addition, the heating, ventilation and/or air conditioning device 100 may be symmetrical about a central axis, for example, and is divided into a left half and a right half by the central axis, and the left half and the right half have the same structure.

For example, referring to fig. 3, the heating, ventilation and/or air conditioning apparatus 100 has a housing 110, and the housing has, for example, a housing internal structure as shown in fig. 1-3. Specifically, the housing defines an inlet 111, a first outlet (here, a blowing foot outlet) 160, and a second outlet 180 (the second outlet 180 may include, for example, a demisting outlet 181 and/or a ventilation outlet 182, as desired).

And referring to fig. 1 and 3, the first outlet (blowing foot outlet) includes, for example, a front blowing foot outlet 161 and a rear blowing foot outlet 162 more specifically; the vent outlets 182 include, for example, more specifically a front vent outlet 1821 and a rear vent outlet 1822.

And the second air flow processing unit 130, the layered dividing wall 150, the first air flow processing unit 120, the first damper 170, the first mixing damper 310, and the second mixing damper 320 are also disposed in the housing, for example, as described above. The second air flow treatment unit 130 is, for example, an evaporator, and is disposed near the inlet 111 of the housing. The first air flow processing unit 120 is, for example, a heater.

The layered partition 150 includes, for example, the first partition 151 and the second partition 152 as described above, and the first partition 151 has, for example, the first partition 1511 and the second partition 1522. And wherein the first partition 1511 partitions the first space V1 and the second space V2, and the second partition 1512 partitions the third space V3 and the fourth space V4. The second partition wall 152 partitions the fifth space V5 and the sixth space V6. And as shown in fig. 6, an upstream end of the second partition wall 152 is connected to an inner side surface of the second air flow treating unit 130, and a downstream end of the second partition wall 152 is connected to a lower surface of the first air flow treating unit 120.

The first damper is a damper component configured for a first opening (foot blowing opening) configured to control an opening degree of the first opening. And as previously described in detail, when the first damper 170 is in the first position, the first damper 170 engages the first partition 1511 to direct the flow of air in the second space V2 out through the second outlet 180 and to direct the flow of air in the first space V1 out through the first outlet 160; when the first damper 170 is in the second position, the first damper 170 closes the first outlet 160 such that both the air flow in the first space V1 and the air flow in the second space V2 flow out of the second outlet 180.

The first mixing damper 310 is configured to adjust the ratio of the air flow through the first air flow treatment unit to the air flow bypassing the first air flow treatment unit, thereby adjusting the temperature of the air flow entering the first space V1. When the first mixing damper 310 is in the fully opened position, the third space V3 is partitioned from the first space V1; the first mixing damper 310 separates the fifth space V5 from the first space V1 when in the completely closed position.

The second mixing damper 320 is configured to adjust the ratio of the air flow through the first air flow treatment unit to the air flow bypassing the first air flow treatment unit, thereby adjusting the temperature of the air flow entering the second space V2. When the second mixing damper 320 is in the fully opened position, the fourth space V4 and the second space V2 are partitioned; the second mixing damper 320 separates the sixth space V6 from the second space V2 when in the fully closed position.

Referring to fig. 4, the demisting damper 191 and the front ventilating damper 1921 are, for example, sliding dampers, and the rear ventilating damper is, for example, a butterfly damper.

Next, the different operation modes of the heating, ventilation and/or air conditioning apparatus 100 will be described in detail.

Foot blowing and ventilating dual mode

Fig. 7 shows a cross-sectional view of the heating, ventilation and/or air conditioning apparatus 100 taken along line A-A in fig. 2, wherein the heating, ventilation and/or air conditioning apparatus 100 is in a foot-blowing ventilation dual mode.

Referring to fig. 7, in the dual foot-blow ventilation mode of the heating, ventilation and/or air conditioning apparatus 100, the first damper 170 is configured in a first position to fully open the foot-blow opening 160 and engage the first partition to direct the airflow. The defogging damper 191 will be in a fully closed position to fully close the defogging outlet, the front and rear vent dampers 1921 and 1922 are opened, and the specific opening position can be adjusted according to the actual needs, for example, so that the front and rear vent outlets are opened with the desired opening.

At this time, for example, the openings of the first and second mixing gates may be further adjusted to control the proportion of the stratified air flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 7, the first and second blend doors 310, 320 are each in an intermediate position, for example.

At this time, the upper layer of the housing inlet is, for example, filled with internal circulating air, the lower layer of the housing inlet is, for example, filled with fresh air, and the air flow in the housing is specifically: for the upper air flow, the upper inlet air flow (here, the inner circulating air inlet air flow) F1i enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow F1i will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space V1 from the left side of the first mixing damper 310 (the air flow direction is shown with a dotted line in fig. 7). The second air flow branch of the upper inlet air flow F1i will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5 and then pass through the first air flow processing unit 120 into the third space V3 and pass through the right side of the first mixing damper 310 into the first space V1 (the air flow direction shown in dotted line in fig. 7), which will be heated by the heater to have a higher temperature than the first air flow branch. Thereafter, in the first space V1, the two air flow branches will mix and form an upper layer output air flow (here, an inner circulation air output air flow) F1o, at which time the first damper 170 in the first position will engage with the first partition and guide the upper layer output air flow F1o in the first space V1 to flow out through the first outlet 160, where the upper layer output air flow F1o is output, for example, through the rear foot outlet 161 and the front foot outlet 162.

For the lower air flow, when fresh air is introduced, the lower intake air flow (here fresh air intake air flow) F2i enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower intake air flow F2i will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and directly enters the second space V2 (the flow direction of the air flow shown in broken line in fig. 7) from the right side of the second mixing damper 320 from the sixth space V6. The second air flow branch of the lower layer intake air flow F2i will pass through the first air flow processing unit (heater) 120, specifically, it will enter the sixth space V6, then pass through the first air flow processing unit 120 into the fourth space V4, and finally enter the second space V2 from the left side of the second mixing damper 320 (the air flow direction shown by dotted lines in fig. 7), and the second air flow branch passing through the first air flow processing unit 120 will be heated by the heater to have a higher temperature than the first air flow branch. Thereafter, in the second space V2, the two air flow branches will mix and form a lower output air flow F2o, and at this time, the first damper 170 in the first position will engage with the first partition and guide the lower output air flow F2o in the second space V2 to flow out through the second outlet, where the lower output air flow (here, fresh air output air flow) F2o is output, for example, through the front ventilation outlet 1821 and the rear ventilation outlet 1822.

Based on the above, the layering entering of the internal circulation air and the fresh air can be realized through the layering partition wall, corresponding airflow flowing spaces are arranged for each layer of airflows, and the first air door is combined with the first partition part in a multiplexing way, so that the good guiding of airflows in the first space and the second space is realized on the basis of good division of the airflow flowing spaces, and the ventilation can be realized through the ventilation outlet through the fresh air, and meanwhile, the foot blowing can be realized through the foot blowing outlet through the internal circulation air, so that ventilation and foot warming are both realized. In addition, the temperature regulation control of the fresh air output air flow F2o of the internal circulation air output air flow F1o respectively output from the foot blowing outlet and the ventilation outlet can be independently realized through the first mixing air door and the second mixing air door, so that the output air flow temperature of the foot blowing outlet and the ventilation outlet can be flexibly regulated. Compared with the current heating, ventilating and/or air conditioning device, the front ventilation opening can only discharge fresh air, and the rear ventilation opening, the front foot outlet and the rear foot outlet all discharge circulating air, the heating, ventilating and/or air conditioning system provided in the application can realize the functions that the front ventilation opening and the rear ventilation opening all discharge fresh air, and the front foot outlet and the rear foot outlet all discharge circulating air.

Foot blowing and demisting dual mode

Fig. 8 shows a cross-sectional view of the heating, ventilation and/or air conditioning apparatus 100 taken along line A-A of fig. 2, wherein the heating, ventilation and/or air conditioning apparatus 100 is in a foot-blowing defogging dual mode.

Referring to fig. 8, in the dual foot-blowing and defogging mode of the heating, ventilation and/or air conditioning apparatus 100, the first damper 170 is configured in a first position to fully open the foot-blowing opening 160 and engage the first partition to effect the directing of the air flow. The defogging damper 191 will be in an open position, and the specific opening position can be adjusted according to the actual needs, for example, to flexibly control the opening of the defogging outlet (for example, the defogging damper is close to the fully open position in fig. 8), and the front ventilation damper 1921 and the rear ventilation damper 1922 are in a fully closed position to fully close the front ventilation outlet and the rear ventilation outlet.

At this time, for example, the opening degrees of the first and second mixing damper 310 and 320 may be further adjusted to control the ratio of the air flow flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 8, the first and second mixing dampers 310, 320 are each in an intermediate position, for example.

In this case, the upper layer of the housing inlet is for example supplied with internal circulating air, and the lower layer of the housing inlet is for example supplied with fresh air. And the air flow in the shell is specifically as follows: for the upper air flow, the upper inlet air flow (here, the inner circulating air inlet air flow) F1i enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow F1i will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space V1 from the left side of the first mixing damper 310 (the air flow direction is shown with a dotted line in fig. 8). The second air flow branch of the upper inlet air flow F1i will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5 and then pass through the first air flow processing unit 120 into the third space V3 and pass through the right side of the first mixing damper 310 into the first space V1 (the air flow direction shown by dotted line in fig. 8), which will be heated by the heater to have a higher temperature than the first air flow branch. Thereafter, in the first space V1, the two air flow branches will mix and form an upper layer output air flow (here, an inner circulation air output air flow) F1o, at which time the first damper 170 in the first position will engage with the first partition and guide the upper layer output air flow F1o in the first space V1 to flow out through the first outlet 160, where the upper layer output air flow (inner circulation air output air flow) F1o is output, for example, through the rear foot-blowing outlet 162 and the front foot-blowing outlet 161.

For the lower air flow (fresh air), this lower inlet air flow (here fresh air inlet air flow) F2i enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower inlet air flow F2i will be split into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and directly from the sixth space V6 from the right side of the second mixing damper 320 into the second space V2 (air flow direction shown in dashed lines in fig. 8). The second air flow branch of the lower layer intake air flow F2i will pass through the first air flow processing unit (heater) 120, specifically, it will enter the sixth space V6, then pass through the first air flow processing unit 120 into the fourth space V4, and finally enter the second space V2 from the left side of the second mixing damper 320 (the air flow direction shown by dotted lines in fig. 8), which will be heated by the heater to have a higher temperature than the first air flow branch. Thereafter, in the second space V2, the two air flow branches will mix and form a lower output air flow (fresh air output air flow) F2o, and at this time, the first damper 170 in the first position will engage with the first partition and direct the lower output air flow F2o in the second space V2 to flow out via the second outlet, where the lower output air flow F2o is output, for example, via the defogging outlet 181.

Based on the above, the layering entering of the internal circulation air and the fresh air can be realized through the layering partition wall, corresponding airflow flowing spaces are formed for each layer of airflows, and the first air door is combined with the first partition part in a multiplexing mode, so that the airflows in the first space and the second space are well guided on the basis of well dividing the airflow flowing spaces, and the internal circulation air can be adopted to blow feet through the foot blowing outlet while the defogging is carried out through the fresh air, and defogging and foot warming are achieved. In addition, the temperature regulation control can be independently realized through the first mixing air door and the second mixing air door, so that the output air flow temperature of the blowing foot outlet and the defogging outlet can be flexibly regulated.

Demisting mode

Fig. 9 shows a cross-sectional view of the heating, ventilation and/or air conditioning apparatus 100 taken along line A-A of fig. 2, wherein the heating, ventilation and/or air conditioning apparatus 100 is in a defogging mode.

Referring to fig. 9, in the heating, ventilation and/or air conditioning apparatus 100 in the defogging mode, the first damper 170 is configured to be in the second position to fully close the foot blowing opening 160. The defogging damper 191 will be in an open position, and a specific opening position may be adjusted according to actual needs, for example, to flexibly control the opening of the defogging outlet, for example, the defogging damper 191 is in a fully open position to fully open the defogging outlet 181 in fig. 9. The front and rear vent dampers 1921 and 1922 are in a fully closed position to fully close the front and rear vent outlets.

At this time, for example, the opening degrees of the first and second mixing dampers 310 and 320 may be further adjusted to control the proportion of the stratified air flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 9, the first and second blend doors 310, 320 are each, for example, in a fully closed position such that each laminar airflow is completely through the first airflow treatment unit 120.

At this time, for example, fresh air is introduced into the upper layer and the lower layer of the inlet of the housing, and the air flow in the housing is specifically: for the upper air flow, the upper intake air flow F1i (here, fresh air intake air flow) enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper intake air flow F1i will all pass through the first air flow treatment unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space V3 through the first air flow treatment unit 120, and enter the first space V1 via the right side of the first air mixing door 310 (the flow direction of the air flow is shown in dotted line in fig. 9).

For the lower air flow, this lower intake air flow (here, fresh air intake air flow) F2i enters, for example, from the inlet lower portion, first it passes through the treatment of the second air flow treatment unit 130 (evaporator), after which the lower intake air flow F2i will all pass through the first air flow treatment unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space V4 through the first air flow treatment unit 120, and finally enter the second space V2 from the left side of the second mixing damper 320 (the flow direction of the air flow is shown by dotted lines in fig. 9).

At this time, the first damper 170 at the second position completely closes the foot outlet, so that the upper inlet air flow F1i in the first space V1 and the lower inlet air flow F2i in the second space V2 together form an output air flow Fo, and the output air flow Fo is output through the demisting outlet 181.

Based on this, under defogging mode for can realize the layering entering of fresh air via layering division wall, and set up corresponding air current flow space for each layer air current, and be in the second position through setting up first air door, on the basis of well dividing air current flow space, make the air current in first space, the second space can all export from defogging export. In addition, the upper air flow and the lower air flow can independently realize temperature regulation control through the first mixing air door and the second mixing air door, so that the temperature control of each layer in the layered air flow can be flexibly carried out.

Foot blowing mode

Fig. 10 shows a cross-sectional view of the heating, ventilation and/or air conditioning apparatus 100 according to line A-A in fig. 2, wherein the heating, ventilation and/or air conditioning apparatus 100 is in a foot-blowing mode.

When the heating, ventilation, and/or air conditioning apparatus 100 is in the foot-blowing mode, the first damper 170 is configured in the first position to fully open the foot-blowing opening 160 and engage the first partition to direct the airflow. The defogging damper 191 will be operatively in an open position, and the specific opening position may be adjusted, for example, as desired to flexibly control the opening of the defogging outlet, for example, in fig. 10 the defogging damper 191 is in an intermediate position between the fully open position and the fully closed position and is close to the fully closed position to open the defogging outlet 181 a small extent to prevent the occurrence of fog on the motor vehicle glass. The front and rear vent dampers 1921 and 1922 are in a fully closed position to fully close the front and rear vent outlets 1821 and 1822.

At this time, for example, the opening degrees of the first and second mixing dampers 310 and 320 may be further adjusted to control the proportion of the stratified air flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 10, the first and second blend doors 310, 320 are each, for example, in a fully closed position such that each laminar airflow is completely through the first airflow treatment unit 120.

At this time, for example, the upper layers of the shell inlets are all filled with internal circulating air, the lower layers of the shell inlets are filled with fresh air, and the air flow in the shell is specifically as follows: for the upper air flow, the upper air flow F1i (here, the inner circulation air flow) enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper air flow F1i will all pass through the first air flow treatment unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space V3 through the first air flow treatment unit 120, and enter the first space V1 (the flow direction of the air flow shown by the dotted line in fig. 10) via the right side of the first air mixing door 310. Thereafter, the air flow entering the first space will be the upper layer output air flow F1o, and the first damper 170 in the first position will be engaged with the first partition and guide the upper layer output air flow F1o in the first space V1 to flow out through the first outlet 160, where the upper layer output air flow (inner circulation air output air flow) F1o is output, for example, through the rear foot blowing outlet 162 and the front foot blowing outlet 161.

For the lower air flow, this lower intake air flow (here, fresh air intake air flow) F2i enters, for example, from the inlet lower portion, first it passes through the treatment of the second air flow treatment unit 130 (evaporator), after which the lower intake air flow F2i will all pass through the first air flow treatment unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space V4 through the first air flow treatment unit 120, and finally enter the second space V2 from the left side of the second mixing damper 320 (the flow direction of the air flow is shown by dotted lines in fig. 10). Thereafter, the air flow entering the second space V2 will be the lower layer output air flow F2o, and the first damper 170 in the first position will engage the first partition and direct the lower layer output air flow F2o within the second space V2 to flow out via the first outlet 160, where the lower layer output air flow (fresh air output air flow) F2o is output, for example, via the defogging outlet 181.

Based on this, under blowing the foot mode, can realize the layering entering of fresh air and inner loop air through layering division wall to set up corresponding air current flow space for each layer air current, and be in the first position through setting up first air door, on the basis of well dividing the air current flow space, can also guide the air current in first space, the second space, make the inner loop output air current in the first space export from blowing the foot, the fresh air output air current in the second space exports from defogging export. In addition, the upper air flow and the lower air flow can be independently controlled by temperature adjustment through the first air mixing door and the second air mixing door, so that the temperature of each layer in the layered air flow can be flexibly controlled, and the air flow temperature output by the foot blowing outlet and the demisting outlet can be independently controlled in the foot blowing mode.

Ventilation mode

Fig. 11 shows a cross-sectional view of the heating, ventilation and/or air conditioning apparatus 100 according to line A-A in fig. 2, wherein the heating, ventilation and/or air conditioning apparatus 100 is in a ventilation mode.

When the heating, ventilation, and/or air conditioning apparatus 100 is in the ventilation mode, the first damper 170 is configured to be in the second position to completely close the foot blowing opening 160. The defogging damper 191 will be in a fully closed position to fully close the defogging outlet 181. The front and rear vent dampers 1921 and 1922 are in a fully open position to fully open the front and rear vent outlets 1821 and 1822.

At this time, for example, the opening degrees of the first and second mixing dampers 310 and 320 may be further adjusted to control the proportion of the stratified air flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 11, the first and second blend doors 310, 320 are each, for example, in a fully open position such that each stratified airflow completely bypasses the first airflow processing unit 120.

At this time, for example, fresh air is introduced into the upper layer and the lower layer of the inlet of the housing, and the air flow in the housing is specifically: for the upper air flow, the upper intake air flow F1i (here, fresh air intake air flow) enters, for example, from the inlet upper portion, first through the process of the second air flow processing unit 130 (evaporator), after which the upper intake air flow F1i will all bypass the first air flow processing unit (heater) 120, specifically, it will enter the fifth space V5, and directly enter the first space V1 from the left side of the first mixing damper 310 (the flow direction of the air flow is shown in broken line in fig. 11).

For the lower air flow, this lower intake air flow (here fresh air intake air flow) F2i enters, for example, from the inlet lower portion, first it passes through the treatment of the second air flow treatment unit 130 (evaporator), after which the lower intake air flow F2i will all bypass the first air flow treatment unit (heater) 120, in particular it will enter the sixth space V6, and then directly enter the second space V2 from the right side of the second mixing damper 320 (the flow direction shown in broken line in fig. 11).

At this time, the first damper 170 in the second position completely closes the foot outlet, so that the upper inlet air flow F1i in the first space V1 and the lower inlet air flow F2i in the second space V2 together form an output air flow Fo, and the output air flow Fo is output through the front ventilation outlet 1821 and the rear ventilation outlet 1822.

Based on the above, in the ventilation mode, the layered entry of the fresh air can be realized through the layered partition wall, corresponding airflow flowing spaces are arranged for each layer of airflow, and the first air door is arranged at the second position, so that the airflows in the first space and the second space can be output from the ventilation outlet on the basis of well dividing the airflow flowing spaces. In addition, the upper air flow and the lower air flow can independently realize temperature regulation control through the first mixing air door and the second mixing air door, so that the temperature control of each layer in the layered air flow can be flexibly carried out.

In some embodiments, a double-deck four-zone heating, ventilation, and/or air conditioning apparatus 100' is also provided. That is, the partition wall is further optimized on the basis of the aforementioned double-layered double-zone arrangement of the heating, ventilating and/or air conditioning apparatus 100, and the auxiliary partition wall is formed on the basis of the central partition wall to divide the housing into four zones.

And the heating, ventilating and/or air conditioning apparatus 100' further includes, for example, a partition wall 140, the partition wall 140 including a central partition wall 141 and two auxiliary partition walls 142.

Referring to fig. 13A and 14, the auxiliary partition 142 is a partition dividing the left half 112 and the right half 113 into two sub-portions, respectively. The auxiliary partition wall may be connected to the central partition wall, for example, and extend parallel to the central partition wall to divide the left and right halves into two sub-portions, respectively, as shown in fig. 14, the auxiliary partition wall 142 dividing the left half 112 into a first left half sub-portion 1121, a second left half sub-portion 1122, for example; the right half sub-portion is divided into a first right half sub-portion 1131 and a second right half sub-portion 1132.

Wherein, referring to fig. 14, the central partition wall 141 and the two auxiliary partition walls 142 divide the first space V1 into four first space sub-areas V1a, V1b, V1c, V1d. The central partition wall 141 and the two auxiliary partition walls 142 divide the second space V2 into four second space sub-areas V2a, V2b, V2c, V2d.

Fig. 15 shows a structure of the partition wall 140 in fig. 12A. Referring to fig. 15, in some embodiments, the two auxiliary dividing walls 142 extend substantially parallel to the central dividing wall 141.

By providing that the auxiliary dividing wall extends substantially parallel to the central dividing wall, it is possible to divide the housing in a simple and easy manner, so that a first space sub-region V1a, V1b, V1c, V1d and a second space sub-region V2a, V2b, V2c, V2d are formed.

With continued reference to fig. 15, in some embodiments, the downstream ends of the two auxiliary dividing walls 142 are provided with laterally extending walls 143 connecting the two auxiliary dividing walls 142.

The laterally extending wall means a member for connecting two auxiliary partition walls, and referring to fig. 15, its extending direction is, for example, substantially perpendicular to the central partition wall and the auxiliary partition walls, and both end portions thereof are respectively joined to the two auxiliary partition walls to connect the two auxiliary partition walls.

For example, the two auxiliary partition walls 142 and the laterally extending walls 143 may be integrally formed.

Based on the above, in the present application, through setting up the lateral extension wall, and further setting up this lateral extension wall and connect two auxiliary walls for can realize the joint fixation of two auxiliary walls better, and be favorable to this layering partition wall in the casing well location.

In some embodiments, the central dividing wall 141 is plugged to the laterally extending wall 143. For example, referring to fig. 15, the central partition wall 141 is, for example, plugged at the centerline of the lateral partition wall.

By arranging the transverse partition wall to be inserted into the two auxiliary walls, the assembly and positioning of the central partition wall and the two auxiliary partition walls can be realized in a simple and convenient manner.

In some embodiments, in the above-described double-layer four-zone structure, the structure of the interior of the housing may be more specifically described, for example, with reference to fig. 12A and 12B, and the housing may include, for example: a first sub-outlet 160a,160b,160c,160d corresponding to each first sub-region of space V1a, V1b, V1c, V1d, and a second sub-outlet 180a,180b,180c,180d corresponding to each second sub-region of space V2a, V2b, V2c, V2 d.

For example, in the example shown in fig. 12A, the first sub-outlet is, for example, a blowing foot outlet, and the second sub-outlet is, for example, a ventilation outlet and a defogging outlet.

And referring to fig. 13A and 14, for each first spatial sub-zone V1a, V1b, V1c, V1d: the heating, ventilation and/or air conditioning apparatus further includes a first sub-damper (e.g., 170a,170b,170c,170d, respectively) disposed within the housing 110, the first sub-damper being operable in a first position and a second position.

It should be appreciated that the first sub-damper may have the structure, type, and movement pattern of the first damper 170 previously described. Specifically, the first sub-damper may be, for example, a sheet-like damper, which may rotate about its own rotation axis between two extreme positions, and the first position and the second position refer to, for example, two extreme positions of the first sub-damper, namely, a fully open position and a fully closed position. Specifically, the first position is, for example, a fully open position of the first sub-damper, such as a position in which the first sub-damper is fully open to abut against the first partition wall (as shown in fig. 16). The second position is, for example, a fully closed position, i.e., a position in which the first sub-damper abuts against the housing interior structure and causes the opening corresponding to the first sub-damper to be fully closed.

The operable first position and second position means that the opening position of the first sub-damper may be adjusted according to the actual situation, for example, the position of the first sub-damper may be adjusted by controlling the rotation direction and position of a rotating motor connected to the first sub-damper, or the position of the first sub-damper may be adjusted by other means, so that the first position or the second position may be set according to the actual requirement. It should be appreciated that embodiments of the present disclosure are not limited by the particular manner in which the first sub-damper opening position is adjusted.

When the first sub-damper is in the first position, the first sub-damper engages the first divider 1511 to direct the flow of air within the respective second sub-region of space corresponding to the first sub-region of space out through the respective second sub-outlet and to direct the flow of air within the first sub-region of space out through the respective first sub-outlet. When the first sub-damper is in the second position, the first sub-damper closes the corresponding first sub-outlet such that both the air flow within the first sub-zone and the air flow within the corresponding second sub-zone corresponding to the first sub-zone flow from the corresponding second sub-outlet.

A cross-sectional view of the first right half 1131 of the housing according to an embodiment of the present disclosure is shown in fig. 16. Next, the case where the first sub damper is in the first position will be described in more detail taking the first right half 1131 of fig. 16 as an example.

Referring to fig. 14 and 15 in combination, the first right half sub-portion 1131 corresponds to, for example, a first space sub-region V1d and a second space sub-region V2d, and a first sub-outlet 160d corresponding to the first space sub-region V1d, for example, a right half front blowing foot outlet is disposed in the housing. And a second sub-outlet 180d is provided in the housing, for example, corresponding to the second sub-space V2d, the second sub-outlet 180d comprising, for example, a right half demister outlet and a right half front ventilation sub-outlet. And the first right half sub-portion 1131 further includes a first sub-damper 170d corresponding to the first space sub-zone V1 d.

And in fig. 15, the first sub-damper 170d is shown against the first partition 1151 of the first partition wall to engage with the first partition 1511 to direct the air flow within the corresponding second sub-space region V2d corresponding to the first sub-space region V1d out through the second sub-outlet 180d (here, for example, out through the front vent outlet) and to direct the air flow within the first sub-space region V1d out through the first sub-outlet 160 d.

In some embodiments, as previously described, the heating, ventilation and/or air conditioning apparatus further comprises a first airflow treatment unit 130, the first airflow treatment unit 130 being disposed within the housing 110 and upstream of the first dividing wall 151.

As described above, the first partition wall 151 further includes the second partition 1512, and the second partition 1512 partitions the third space V3 and the fourth space V4 in the housing 110. Wherein a part of the air flow passing through the first air flow processing unit 130 enters the third space V3, and another part enters the fourth space V4. The second partition, the third space and the fourth space have been described in detail in conjunction with fig. 5, and will not be described here again.

Referring to fig. 13A, the heating ventilation and/or air conditioning apparatus further includes: a first blend door (e.g., first blend doors 310a,310b,310c,310d, respectively) disposed corresponding to each first space subarea V1a, V1b, V1c, V1d and/or a second blend door (e.g., second blend doors 320a,320b,320c,320d, respectively) disposed corresponding to each second space subarea V2a, V2b, V2c, V2 d.

And wherein said central dividing wall 141 and two auxiliary dividing walls 142 divide said third space V3 into four third space sub-areas, e.g. third space sub-areas V3a, V3b, V3c, V3d, respectively (of which third space sub-areas V3c, V3d are schematically shown in fig. 16, 17); the central dividing wall 141 and the two auxiliary dividing walls 142 divide the fourth space V4 into, for example, four fourth space sub-regions V4a, V4b, V4c, V4d (of which the third space sub-regions V4c, V4d are schematically shown in fig. 16, 17).

And similar to the above-described detailed description with reference to the double-layer double-region structure, for each first spatial sub-region V1a, V1b, V1c, V1d: a third sub-zone of space corresponding to the first sub-zone of space is separated from the first sub-zone of space when the first mixing damper corresponding to the first sub-zone of space is in a fully open position.

For example, taking the first sub-zone V1d as an example, referring to fig. 16, where, for example, a first blend door 310d corresponding to the first sub-zone V1d is shown, if the first blend door 310d in fig. 16 is in the fully open position as in the previous fig. 5, then, for example, the third sub-zone V3d may be separated from the first sub-zone V1 d.

And similar to the above described detailed description with reference to the double layer double region structure, for each second spatial sub-region V2a, V2b, V2c, V2d: the fourth sub-zone corresponding to the second sub-zone is separated from the second sub-zone when the second mixing damper corresponding to the second sub-zone is in the fully open position.

For example, taking the second space sub-zone V2d as an example, referring to fig. 16, where, for example, a first mixing damper 320d corresponding to the second space sub-zone V2d is shown, if the second mixing damper 320d in fig. 16 is in the fully open position as in the previous fig. 5, then, for example, the fourth space sub-zone V4d may be separated from the second space sub-zone V2 d.

Based on the above, in the present application, by providing that the housing includes a first mixing damper corresponding to each first space subarea and/or a second mixing damper corresponding to each second space subarea and a first air flow processing unit (e.g., a heater), it is possible to adjust the temperature of the air flow entering the corresponding first space subarea according to actual needs by the opening position of the first mixing damper corresponding to the first space subarea; and adjusting the temperature of the air flow entering the second space subarea through the opening position of the second air mixing door corresponding to the second space subarea, so as to realize independent adjustment of the air flow temperature of different layers and different subareas after layering and subareas. A plurality of third and fourth space subregions are separated in the shell through a second partition part and a partition wall, and the third space subregion is separated from the first space subregion when the corresponding first air mixing door is in a fully closed position; the fourth and second sub-regions of space are separated when the respective second mixing damper is in the fully closed position, enabling multiplexing of the first and second mixing dampers as spacers between adjacent spaces, thereby optimizing the structural layout within the housing.

In some embodiments, the layered partition 150 also has a second partition 152. The second partition wall 152 is located upstream of the first air flow processing unit 130, and the second partition wall 152 partitions the fifth space V5 and the sixth space V6 within the housing 110. Wherein a part of the air flow passing through the first air flow processing unit 130 is from the fifth space V5, and another part is from the sixth space V6.

And for each second spatial sub-zone V2a, V2b, V2c, V2d: the sixth space V6 is separated from the second space sub-zone when the second mixing damper corresponding to the second space sub-zone is in the fully closed position.

It should be appreciated that the fully closed position refers to the position where the second sub-damper separates the second sub-zone of space.

The second spatial first sub-zone and the second spatial second sub-zone refer to two regions of the second spatial sub-zone. It should be appreciated that embodiments of the present disclosure are not limited by the specific spatial volumes and spatial locations of the second spatial first sub-region and the second spatial second sub-region.

Fig. 19 illustrates a cross-sectional view of the second right half sub-section 1132, wherein a second spatial first sub-region and a second spatial second sub-region are labeled, in accordance with an embodiment of the present disclosure. With reference to fig. 19, the second sub-damper will be described in more detail below, taking the second right half 1132 as an example, for example.

As shown in fig. 17 and 19, the second right half 1132 corresponds to the second subspace V2c, and in fig. 19, for example, the second sub damper 171c is shown in a fully closed position in the second subspace V2c, where the second sub damper 171c is, for example, a butterfly damper, and the fully closed position is where the second sub damper is in a substantially horizontal position. In the fully closed position, one end of the second sub-damper 171c is engaged with the first partition 1511, and the other end of the second sub-damper 171c is engaged with the transversely extending wall 143 of the partition wall, for example, so as to partition the second sub-space into the second sub-space first sub-area V2c-1 and the second sub-space second sub-area V2c-2 via the first partition 1511, the second sub-damper 171c and the transversely extending wall 143. And the second sub-zone of the second space are for example in communication with different second sub-outlets, respectively. In particular, the second space first sub-zone may for example be in communication with a front ventilation sub-outlet and a demister sub-outlet, and the second space second sub-zone may for example be in communication with a rear ventilation sub-outlet.

Based on the above, in the present application, by setting the second sub-damper in the second space sub-area corresponding to the lateral extension wall, and setting the second sub-damper to be engaged with the first partition and the lateral extension wall when in the fully closed position, and dividing the second space sub-area into the second space first sub-area and the second space second sub-area, further separation of the sub-space inside the housing can be flexibly realized through cooperation of the set second sub-damper with the housing internal structure and the partition wall structure, thereby being beneficial to flexibly setting flow paths of the layered air flow in each different area according to actual needs, and being beneficial to realizing multiple working modes.

In some embodiments, with further reference to fig. 19, the second sub-outlet may comprise, for example, a vent sub-outlet. Further, the ventilation sub-outlets may also include, for example, a front ventilation sub-outlet and a rear ventilation sub-outlet.

In the second sub-zone of space corresponding to the transversely extending wall 143, the heating, ventilation and/or air conditioning device is for example also provided with a third sub-damper. The third sub-damper may be, for example, a butterfly damper, or may be of another type according to actual needs.

And wherein for each second spatial sub-zone corresponding to the laterally extending wall: when the third sub-damper is in the fully closed position, the third sub-damper engages the housing to close the corresponding ventilation sub-outlet.

The fully closed position of the third sub-damper refers to the position of the third sub-damper for closing the corresponding ventilation sub-outlet.

For example, referring to fig. 19, in the second right half 1132 shown in fig. 19, the second sub-outlets include, for example, a demister outlet 181c, a front ventilation sub-outlet 1821c, and a rear ventilation sub-outlet 1822c. And the third sub-damper 172c is, for example, disposed adjacent to the rear ventilation sub-outlet 1822c and is a butterfly damper, and when the third sub-damper is in the fully closed position, two butterfly vanes of the third sub-damper are, for example, respectively engaged with the inner wall of the housing to form a spacer to close the corresponding rear ventilation sub-outlet 1822c.

Based on the above, in the present application, by setting the third sub-damper in the second space subarea corresponding to the transversely extending wall, and setting the third sub-damper at the fully closed position, the third sub-damper cooperates with the housing to close the corresponding ventilation sub-outlet, so that the corresponding ventilation sub-outlet in the second space subarea can be closed by adjusting the third sub-damper according to actual needs, thereby being beneficial to flexibly setting the flow path and the output outlet of the air flow according to actual needs, and thus being capable of realizing a multi-mode and multifunctional heating, ventilation and/or air conditioning device.

Next, the structure and the relationship of the components of the heating, ventilating and/or air conditioning apparatus 100 'will be described in more detail in connection with the application of the heating, ventilating and/or air conditioning apparatus 100' in a plurality of different operation modes.

The double-layer four-zone means that the heating, ventilating and/or air conditioning apparatus 100' has four sub-portions (a first left half sub-portion, a second left half sub-portion, a first right half sub-portion, and a second right half sub-portion) divided by a partition wall along a plane where the central partition wall is located, and has two-layer air flow inlets (an upper-layer air flow inlet and a lower-layer air flow inlet) divided by a partition wall, that is, eight independent air flow inlets (which may be, for example, same air flow types or different air flow types) are provided, and the 8 independent air flow inlets are respectively divided into corresponding air flow paths and temperature control dampers inside the housing, so that each of the intake air flows entering the 8 independent air flow inlets is independently temperature-adjusted, and can be directed to different outlet channels according to different modes. And through the arrangement of the corresponding outlets, for the heating, ventilation and/or air conditioning device, independent foot blowing outlets, ventilation outlets and defrosting outlets are arranged in the four directions of the left front, the left rear, the right front and the right rear, and the foot blowing outlets, the ventilation outlets and the defrosting outlets can output airflows with different types, different temperatures and different air flows. Thus, the foot blowing, ventilation and defrosting functions independent of each other can be well provided for the front passenger side (right side), the front driver side (left side), the rear left passenger side and the rear right passenger side of the motor vehicle.

For example, the double-layered four-zone heating, ventilating and/or air conditioning apparatus 100 'illustrated herein has the structure of the heating, ventilating and/or air conditioning apparatus 100' described in detail with reference to fig. 12A to 19, which may include, for example, the housing 110, the layered partition wall 150, the first processing unit 120, the second processing unit 130, and the corresponding connection structures, as described above, and will not be described again herein.

And the heating, ventilating and/or air conditioning apparatus 100 'includes, for example, a partition wall 140 (including a central partition wall, an auxiliary partition wall extending parallel to the central partition wall, a lateral extending wall) as shown in fig. 15, and the central partition wall 141 divides the heating, ventilating and/or air conditioning apparatus 100' into a left half 112 and a right half 113 symmetrical along a straight line where the central partition wall is located, and the auxiliary partition wall 142 divides the left half 112 into, for example, a first left half sub-portion 1121, a second left half sub-portion 1122; the right half sub-portion is divided into a first right half sub-portion 1131 and a second right half sub-portion 1132, the central partition wall 141 and the two auxiliary partition walls 142 divide the first space V1 into four first space sub-areas V1a, V1b, V1c, V1d, and the second space V2 into four second space sub-areas V2a, V2b, V2c, V2d.

And for each first sub-region of space, for example, a corresponding first sub-outlet. Specifically, for example, for a first space subsection V1a in the first left half sub-section 1121, it has a left half front blowing foot outlet; for the first space subsection V1b in the second left half sub-section 1121, it has a left half rear foot-blowing outlet; for the first space subsection V1d in the first right half sub-section 1131, it has a right half front foot-blowing outlet; for the first space subsection V1c in the second right half sub-section 1131, it has a right half rear foot-blowing outlet.

Furthermore, for each second sub-zone of space, there is for example a corresponding second sub-outlet. In this example, the second sub-outlets include, for example, a demister outlet and a ventilation sub-outlet provided for each of the second sub-regions of space. In particular, for the ventilation sub-outlet, for example for the second space sub-zone V2a in the first left half 1121, it has a left half front ventilation sub-outlet; for a second spatial sub-zone V2b in the second left half sub-zone 1121, it has a left half rear ventilation sub-outlet; for the second spatial sub-zone V2d in the first right half sub-zone 1131, it has a right half front ventilation sub-outlet; for the second spatial sub-zone V2c in the second right half sub-section 1131, it has a right half rear ventilation sub-outlet.

Considering the symmetrical relationship of the left half and the right half and the corresponding arrangement positions of the sub outlets, the left half and the right half have the same structure. In the same mode, the first left half sub-part and the first right half sub-part can have the same arrangement mode and the same airflow path; the second left-half sub-portion and the second right-half sub-portion may have, for example, the same arrangement and the same airflow path. Accordingly, in the following description of each operation mode, the specific structural configuration and airflow path will be described by taking the right half sub-portion (including the first right half sub-portion and the second right half sub-portion) as an example, and those skilled in the art will understand that, according to the symmetrical relationship, the left half portion may be correspondingly disposed so as to be in a corresponding mode and realize a corresponding function.

Foot blowing and ventilating dual mode

FIG. 20A illustrates a cross-sectional view of a first right half 1131 of a heating, ventilation and/or air conditioning device 100', wherein the heating, ventilation and/or air conditioning device 100' is in a foot-blowing ventilation dual mode; fig. 20B shows a cross-sectional view of the second right half 1132 of the heating, ventilation and/or air conditioning device 100', wherein the heating, ventilation and/or air conditioning device 100' is in a foot-blowing ventilation dual mode.

Referring to fig. 20A, in the hvac device 100' in the foot-blowing ventilation dual mode, the first right half 1131 corresponds to the first space sub-area V1d and the second space sub-area V2d, for example, and the first sub-outlet 160d corresponding to the first space sub-area V1d, here the right half front-blowing foot outlet 161d, is disposed in the housing. And a second sub-outlet 180d is provided in the housing, for example, corresponding to the second sub-space V2d, the second sub-outlet comprising, for example, a right half demister sub-outlet 181d and a right half front ventilation sub-outlet 1821d. And the first right half sub-portion 1131 further includes a first sub-damper 170d corresponding to the first space sub-zone V1 d.

Referring to fig. 20A, in the heating, ventilation and/or air conditioning apparatus 100 in the foot-blowing ventilation dual mode, the first sub-damper 170d in the first right half 1131 is now configured in the first position to fully open the right half front foot-blowing sub-outlet 161d and engage with the first partition to effect the directing of the air flow. The defogging sub damper 191d will be in a fully closed position to fully close the defogging sub outlet 181d and the front ventilation sub damper 1921d will be opened, and the specific opening position may be adjusted as actually needed to open the outlet at a desired opening.

At this time, for example, the opening degrees of the first and second mixing dampers 310d and 320d may be further adjusted to control the proportion of the stratified air flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 20A, the first and second mixing dampers 310d and 320d are each in an intermediate position, for example.

At this time, the upper layer of the housing inlet of the first right half is, for example, filled with internal circulating air, the lower layer of the housing inlet of the first right half is, for example, filled with fresh air, and the air flow in the housing is specifically: for the upper air flow, the upper inlet air flow (here, the inner circulating air inlet air flow) f1i_d enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_d will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1d from the left side of the first mixing damper 310d (the air flow direction is shown in dashed line in fig. 20A). The second air flow branch of the upper inlet air flow f1i_d will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5 and then through the first air flow processing unit 120 into the third space sub-area V3d and into the first space sub-area V1d via the right side of the first mixing damper 310d (the air flow direction as shown in dotted line in fig. 20A), which will be heated by the heater to have a higher temperature with respect to the first air flow branch. Thereafter, in the first sub-zone of space V1d, the two air flow branches will mix and form an upper output air flow (herein, the internal circulating air output air flow) f1o_d (it will be understood that the arrows in the drawing are only schematic, and that the output air flow is actually output through the side opening of the housing), at which time the first sub-damper 170d in the first position will engage with the first partition and direct the upper output air flow f1o_d in the first sub-zone of space V1d to flow out through the right half front-blowing foot outlet 161 d.

For the lower air flow, when fresh air is introduced, the lower intake air flow (here fresh air intake air flow) f2i_d enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower intake air flow f2i_d will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and enters the second space sub-area V2d (the air flow direction shown in broken line in fig. 20A) directly from the right side of the second mixing damper 320d from the sixth space V6. The second air flow branch of the lower layer intake air flow f2i_d will pass through the first air flow processing unit (heater) 120, in particular, it will enter the sixth space V6, then through the first air flow processing unit 120 into the fourth space subregion V4d, finally from the left side of the second mixing damper 320d into the second space subregion V2d (the air flow direction shown by dotted lines in fig. 20A), which will be heated by the heater to have a higher temperature than the first air flow branch. Thereafter, in the second space V2, the two air flow branches will mix and form a lower output air flow f2o_d, and at this time, the first sub-damper 170d in the first position will engage the first partition and direct the lower output air flow f2o_d within the second space sub-area V2d to be output via the right half front ventilation sub-outlet 1821 d.

Referring to fig. 20B, in the dual foot-blow ventilation mode of the heating, ventilation and/or air conditioning apparatus 100', the first sub-damper 170c in the second right half 1132 is configured in the first position to fully open the right half rear foot-blow sub-outlet 162c and engage the first partition to effect the directing of the air flow. The defogging sub-damper 191c will be in a fully closed position to fully close the defogging sub-outlet 181c, and the third sub-damper (here, as a front ventilation sub-damper) 172c is, for example, in an open position, and the specific opening position may be, for example, adjusted as actually needed to cause the right half rear ventilation sub-outlet 1822c to be opened at a desired opening.

At this time, for example, the opening degrees of the first and second mixing dampers 310c and 320c may be further adjusted to control the proportion of the stratified air flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 20B, the first and second mixing dampers 310c and 320c are each in an intermediate position, for example.

At this time, the upper layer of the housing inlet of the second right half is, for example, filled with internal circulating air, the lower layer of the housing inlet of the second right half is, for example, filled with fresh air, and the air flow in the housing is specifically: for the upper air flow, the upper inlet air flow (here, the inner circulating air inlet air flow) f1i_c enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_c will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1c from the left side of the first mixing damper 310c (the air flow direction is shown in dashed lines in fig. 20B). The second air flow branch of the upper inlet air flow f1i_c will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5 and then through the first air flow processing unit 120 into the third space sub-area V3c and into the first space sub-area V1c via the right side of the first mixing damper 310c (the air flow direction as shown in dotted line in fig. 20B), which will be heated by the heater to have a higher temperature than the first air flow branch. Thereafter, in the first sub-zone of space V1c, the two air flow branches will mix and form an upper output air flow (here, an inner circulating air output air flow) f1o_c, at which point the first sub-damper 170c in the first position will engage the first partition and direct the upper output air flow f1o_c within the first sub-zone of space V1c to flow out through the right half rear foot-blowing outlet 162 c.

For the lower air flow, when fresh air is introduced, the lower intake air flow (here fresh air intake air flow) f2i_c enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower intake air flow f2i_c will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and enters the second space sub-area V2c (the air flow direction shown in broken line in fig. 20B) directly from the right side of the second mixing damper 320c from the sixth space V6. The second air flow branch of the lower layer intake air flow f2i—c will pass through the first air flow processing unit (heater) 120, in particular, it will enter the sixth space V6, then through the first air flow processing unit 120 into the fourth space subregion V4c, finally from the left side of the second mixing damper 320c into the second space subregion V2c (the air flow direction shown by dotted lines in fig. 20B), which will be heated by the heater to have a higher temperature than the first air flow branch. Thereafter, in the second space sub-zone V2c, the two air flow branches will mix and form a lower output air flow f2o_c, and at this time, the second sub-damper 171c in the fully closed position will engage with the first partition and the laterally extending wall to partition the second space first sub-zone V2c-1 and the second space second sub-zone V2c-2 in the second space sub-zone V2c, and direct the lower output air flow f2o_c in the second space V2c to flow only in the second space first sub-zone V2c-1 and output via the right half rear ventilation sub-outlet 1822 c.

It should be appreciated that, considering that the first and second mixing dampers are respectively disposed corresponding to each of the first and second sub-regions and each have a temperature adjusting function, a process of implementing temperature adjustment through the first and second mixing dampers will not be described in detail hereinafter.

Based on the above, the inner circulation air and the fresh air can enter in a layered manner through the layered separation wall and the comprehensive arrangement of the layered separation wall, and the functions of controlling the temperature independently on the left and right (as described in the previous description of the double-layer double-zone) are further realized through the arrangement of the separation wall and the shell structure on the basis of the corresponding airflow flowing space. Specifically, as can be seen from the operation modes described in detail in connection with the right half (the left half may have corresponding airflow passages based on the symmetrical structure), in this case, it is possible to provide different air flow paths, opening control dampers for the front foot sub-outlet of the right half and the rear foot sub-outlet of the right half, and perform independent temperature control, and provide different air flow paths, opening control dampers for the front ventilation sub-outlet of the right half and the rear ventilation sub-outlet of the right half, and perform independent temperature control. Thus, for the heating, ventilation and/or air conditioning device, independent blowing foot outlets and ventilation outlets are arranged in the four directions of the left front, the left rear, the right front and the right rear, and each blowing foot outlet and ventilation outlet can output airflows with different types, different temperatures and different air flows.

Defogging priority mode

FIG. 21A illustrates a cross-sectional view of a first right half 1131 of a heating, ventilation and/or air conditioning device 100', wherein the heating, ventilation and/or air conditioning device 100' is in a defogging priority mode; fig. 21B illustrates a cross-sectional view of the second right half 1132 of the heating, ventilation and/or air conditioning device 100', wherein the heating, ventilation and/or air conditioning device 100' is in a defogging priority mode.

Referring to fig. 21A, in the heating, ventilation and/or air conditioning apparatus 100' in the defogging priority mode, the first sub-damper 170d in the first right half 1131 is configured to be in the second position to fully close the right half front foot-blowing outlet 161 d. The defogger damper 191d will be in a fully open position to fully open the defogger outlet 181d and the front vent damper 1921d is closed to close the right half front vent sub outlet 1821d.

At this time, for example, the opening degrees of the first and second mixing dampers 310d and 320d may be further adjusted to control the proportion of the stratified air flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 21A, the first and second mixing dampers 310d and 320d are each in an intermediate position, for example.

At this time, for example, fresh air is introduced into the upper layer and the lower layer of the inlet of the housing of the first right half, and the airflow in the housing is specifically: for the upper air flow, the upper inlet air flow (here fresh air inlet air flow) f1i_d enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_d will be split into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1d from the left side of the first mixing damper 310d (the air flow direction is shown in dashed lines in fig. 21A). The second air flow branch of the upper inlet air flow f1i_d will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5, and then through the first air flow processing unit 120 into the third space sub-zone V3d and into the first space sub-zone V1d via the right side of the first mixing damper 310d (the air flow direction is shown in dotted line in fig. 21A).

For the lower air flow, when fresh air is introduced, the lower intake air flow (here fresh air intake air flow) f2i_d enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower intake air flow f2i_d will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and enters the second space sub-area V2d (the air flow direction shown in broken line in fig. 21A) directly from the right side of the second mixing damper 320d from the sixth space V6. The second air flow branch of the lower inlet air flow f2i—d will pass through the first air flow processing unit (heater) 120, in particular, it will enter the sixth space V6, then through the first air flow processing unit 120 into the fourth space sub-zone V4d, and finally from the left side of the second mixing damper 320d into the second space sub-zone V2d (the air flow direction is shown in dotted line in fig. 21A).

At this time, since the first sub-damper 170d in the second position completely closes the right half front foot-blowing outlet 161d, the upper inlet air flow f1i_d in the first space sub-zone V1d and the lower inlet air flow f2i_d in the second space sub-zone V2d form an output air flow fo_d together, and the output air flow fo_d is output through the defogger outlet 181 d.

Referring to fig. 21B, in the heating, ventilation and/or air conditioning apparatus 100' is in the defogging priority mode, the first sub-damper 170c in the second right half 1132 is configured to be in the second position to fully close the right half rear foot-blowing outlet 162 c. The defogger damper 191c will be in a fully open position to fully open the defogger outlet 181c and the third sub damper (here, a front ventilation sub damper) 172c will be in a fully closed position, for example, to engage the housing inner wall and fully close the right half rear ventilation sub outlet 1822 c.

At this time, for example, fresh air is introduced into the upper layer and the lower layer of the inlet of the housing of the second right half, and the airflow in the housing is specifically: for the upper air flow, the upper inlet air flow (here fresh air inlet air flow) f1i_c enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_c will be split into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1c from the left side of the first mixing damper 310c (the air flow direction is shown in dashed lines in fig. 21B). The second air flow branch of the upper inlet air flow f1i_c will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5, and then through the first air flow processing unit 120 into the third space sub-zone V3c and into the first space sub-zone V1c via the right side of the first mixing damper 310c (the air flow direction is shown in dotted line in fig. 21B).

For the lower air flow, when fresh air is introduced, the lower inlet air flow (here fresh air inlet air flow) f2i_c enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower inlet air flow f2i_c will be split into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and directly from the sixth space V6 from the right side of the second mixing damper 320c into the second space first sub-zone V2c-1 (the air flow direction shown in dashed lines in fig. 21B). The second air flow branch of the lower inlet air flow f2i—c will pass through the first air flow processing unit (heater) 120, in particular it will enter the sixth space V6, then through the first air flow processing unit 120 into the fourth space sub-zone V4c, finally from the left side of the second mixing damper 320c into the second space first sub-zone V2c-1 (the air flow direction as shown by dotted lines in fig. 21B), at which time the second sub-damper 171c in the open position will cooperate with the first partition to effect a guiding of the inlet air flow such that the inlet air flow (including both air flow branches) enters the second space second sub-zone V2c-2 from the second space first sub-zone V2c-1 via a path between the second sub-damper 171c and the first partition.

At this time, since the first sub-damper 170c in the second position completely closes the right half rear foot-blowing outlet 162c, the upper inlet air flow f1i_c in the first space sub-zone V1c and the lower inlet air flow f2i_c in the second space sub-zone V2c form an output air flow fo_c together, and the output air flow fo_c is output through the defogger outlet 181 c.

Based on this, in the defogging priority mode, the corresponding foot blowing sub-outlet is completely closed through the first sub-damper in each first space subarea, the right half rear ventilation sub-outlet is completely closed through the third sub-damper, and the air flow is guided through the second sub-damper and the first partition portion in cooperation, so that, for example, both the upper layer air intake flow and the lower layer air intake flow are output through the defogging sub-opening.

Foot blowing and demisting dual mode

FIG. 22A illustrates a cross-sectional view of the first right half 1131 of the heating, ventilation and/or air conditioning apparatus 100', wherein the heating, ventilation and/or air conditioning apparatus 100' is in a foot-blowing defogging dual mode; fig. 22B shows a cross-sectional view of the second right half 1132 of the heating, ventilation and/or air conditioning apparatus 100', wherein the heating, ventilation and/or air conditioning apparatus 100' is in a foot-blowing defogging dual mode.

Referring to fig. 22A, in the dual foot and mist blowing mode of the heating, ventilation and/or air conditioning apparatus 100', the first sub-damper 170d in the first right half 1131 is configured in a first position to fully open the right half front foot-blowing sub-outlet 161d and engage the first partition to effect the directing of the air flow. The defogging sub damper 191d will be in an open position to open the defogging sub outlet 181d, and the specific opening position may be adjusted, for example, according to actual needs to cause the outlet to be opened at a desired opening. The front vent sub-damper 1921d is in a fully-closed position to close the right half front vent sub-outlet 1821 d.

At this time, for example, the opening degrees of the first and second mixing dampers 310d and 320d may be further adjusted to control the proportion of the stratified air flowing through and bypassing the first air flow processing unit 120 (heater). In the example shown in fig. 22A, the first and second mixing dampers 310d and 320d are each in an intermediate position, for example.

At this time, the upper layer of the housing inlet of the first right half is, for example, filled with internal circulating air, the lower layer of the housing inlet of the first right half is, for example, filled with fresh air, and the air flow in the housing is specifically: for the upper air flow, the upper inlet air flow (here, the inner circulating air inlet air flow) f1i_d enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_d will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1d from the left side of the first mixing damper 310d (the air flow direction is shown in dashed line in fig. 22A). The second air flow branch of the upper inlet air flow f1i_d will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5, and then through the first air flow processing unit 120 into the third space sub-zone V3d and into the first space sub-zone V1d via the right side of the first mixing damper 310d (the air flow direction is shown in dotted line in fig. 22A). Thereafter, in the first sub-zone of space V1d, the two air flow branches will mix and form an upper output air flow (here, an inner circulating air output air flow) f1o_d, at which point the first sub-damper 170d in the first position will engage the first partition and direct the upper output air flow f1o_d within the first sub-zone of space V1d to flow out through the right half front blowing foot outlet 161 d.

For the lower air flow, when fresh air is introduced, the lower intake air flow (here fresh air intake air flow) f2i_d enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower intake air flow f2i_d will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and enters the second space sub-area V2d (the air flow direction shown in broken line in fig. 22A) directly from the right side of the second mixing damper 320d from the sixth space V6. The second air flow branch of the lower inlet air flow f2i—d will pass through the first air flow processing unit (heater) 120, in particular, it will enter the sixth space V6, then through the first air flow processing unit 120 into the fourth space sub-zone V4d, and finally from the left side of the second mixing damper 320d into the second space sub-zone V2d (the air flow direction is shown in dotted line in fig. 22A). Thereafter, in the first sub-zone of space V2d, the two air flow branches will mix and form a lower output air flow F2o_d (here fresh air output air flow), and this lower output air flow F2o_d is output via the demister outlet 181 d.

Referring to fig. 22B, in the foot-blow defogging dual mode, the first sub-damper 170c in the second right half 1132 is now configured in a first position to fully open the right half rear foot-blow outlet 162c and engage the first partition to direct the airflow. The defogging sub-damper 191c will be in an open position to open the defogging sub-outlet 181c, and the specific opening position may be adjusted, for example, according to actual needs, so that the defogging sub-outlet 181c is opened at a desired opening. The third sub-damper (here, a front ventilation sub-damper) 172c is, for example, in a fully closed position to close the right half rear ventilation sub-outlet 1822 c.

At this time, the upper layer of the housing inlet of the second right half is, for example, filled with internal circulating air, the lower layer of the housing inlet of the second right half is, for example, filled with fresh air, and the air flow in the housing is specifically: for the upper air flow, the upper inlet air flow (here, the inner circulating air inlet air flow) f1i_c enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_c will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1c from the left side of the first mixing damper 310c (the air flow direction is shown in dashed lines in fig. 22B). The second air flow branch of the upper inlet air flow f1i_c will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5, and then through the first air flow processing unit 120 into the third space sub-zone V3c and into the first space sub-zone V1c via the right side of the first mixing damper 310c (the air flow direction is shown in dotted line in fig. 22B). Thereafter, in the first sub-zone of space V1c, the two air flow branches will mix and form an upper output air flow (here, an inner circulating air output air flow) f1o_c, at which point the first sub-damper 170c in the first position will engage the first partition and direct the upper output air flow f1o_c within the first sub-zone of space V1c to flow out through the right half rear foot-blowing outlet 162 c.

For the lower air flow, in the case shown in fig. 22B, the second sub-damper 171c is in a completely closed state, for example, to block the second space first sub-zone V2c-1 and the second space second sub-zone V2c-2, and the lower air flow does not enter the second space second sub-zone V2c-2, for example, and is not output through the defogger outlet 181 c.

At this time, the defogging function may be realized based on, for example, only the lower output air flow f2o_d outputted from the defogger outlet 181d in fig. 22A. However, it should be appreciated that depending on the circumstances, for example, in the case where it is desired to further increase the defogging air flow, the second sub-damper 171c may also be configured, for example, to be in the open position shown in fig. 21B to cooperate with the housing inner wall and direct the lower layer intake air flow to be output via the defogging sub-outlet 181c, so that the defogging air flow is jointly output via the defogging sub-outlet 181c and the defogging sub-outlet 181d to achieve a more powerful defogging function.

Based on the above, in the foot blowing and demisting dual mode, on one hand, the first sub-air door in each first space sub-area is matched with the first partition part to realize the division of the first space sub-area and the second space sub-area, and the circulating air in the upper layer is guided to be output through the corresponding front/rear foot part sub-outlets, so that the foot blowing function through the internal circulating air is realized. On the other hand, the lower fresh air layer can be used for realizing the demisting function through the cooperation of the second sub-air door in each second space subarea and the inner wall.

Foot blowing mode

FIG. 23A illustrates a cross-sectional view of the first right half 1131 of the heating, ventilation and/or air conditioning device 100', wherein the heating, ventilation and/or air conditioning device 100' is in a foot-blowing mode; fig. 23B shows a cross-sectional view of the second right half 1132 of the heating, ventilation and/or air conditioning device 100', wherein the heating, ventilation and/or air conditioning device 100' is in a foot-blowing mode.

Referring to fig. 23A, in the foot-blowing mode of the heating, ventilation and/or air conditioning apparatus 100', the first sub-damper 170d in the first right half 1131 is configured in a first position to fully open the right half front foot-blowing sub-outlet 161d and engage with the first partition to effect the directing of the air flow. The defogging sub-damper 191d will be in an open position to slightly open the defogging sub-outlet 181d to prevent the occurrence of fog on the glass during the foot blowing process. In this case, the airflow path and the structural configuration in the foot blowing mode are the same as those in the foot blowing demisting dual mode, and will not be described herein.

Referring to fig. 22B, in this foot-blowing mode, the first sub-damper 170c in the second right half 1132 is now configured in the first position to fully open the right half rear foot-blowing outlet 162c and engage the first partition to effect the directing of the air flow. The defogging sub-damper 191c will be in an open position to open the defogging sub-outlet 181c, and the specific opening position may be adjusted, for example, according to actual needs, so that the defogging sub-outlet 181c is opened at a desired opening. The third sub-damper (here, a front ventilation sub-damper) 172c is, for example, in a fully closed position to close the right half rear ventilation sub-outlet 1822 c.

At this time, the upper layer of the inlet of the second right half shell is, for example, filled with internal circulating air, and the airflow in the shell is specifically: for the upper air flow, the upper inlet air flow (here, the inner circulating air inlet air flow) f1i_c enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_c will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1c from the left side of the first mixing damper 310c (the air flow direction is shown in dashed line in fig. 23B). The second air flow branch of the upper inlet air flow f1i_c will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5, and then through the first air flow processing unit 120 into the third space sub-zone V3c and into the first space sub-zone V1c via the right side of the first mixing damper 310c (the air flow direction is shown in dotted line in fig. 23B). Thereafter, in the first sub-zone of space V1c, the two air flow branches will mix and form an upper output air flow (here, an inner circulating air output air flow) f1o_c, at which point the first sub-damper 170c in the first position will engage the first partition and direct the upper output air flow f1o_c within the first sub-zone of space V1c to flow out through the right half rear foot-blowing outlet 162 c.

For the lower air flow, in the case shown in fig. 23B, for example, the lower air intake may not be introduced, where the second sub-damper 171c is in a completely closed state, for example, to block the second space first sub-zone V2c-1 and the second space second sub-zone V2c-2, and the lower air intake may not enter the second space second sub-zone V2c-2, for example, and may not be output through the defogger outlet 181 c. However, it should be appreciated that depending on the circumstances, fresh air may also be introduced as the lower inlet air flow, in which case the second sub-damper 171c may also be configured, for example, to be in the open position shown in fig. 21B to cooperate with the housing inner wall and direct the lower inlet air flow to be output via the defogger outlet 181 c.

Based on the above, in the foot blowing mode, the first sub-air door in each first space sub-area is matched with the first partition part to divide the first space sub-area and the second space sub-area, and the circulating air in the upper layer is guided to be output through the corresponding front/rear foot sub-outlet, so that the foot blowing function through the internal circulating air is realized. On the other hand, according to actual conditions, the demister outlets can be selectively opened, and the lower fresh air can be used for realizing the demisting function through the cooperation of the second sub-air doors in each second space subarea and the inner wall.

At this time, for example, fresh air is introduced into the upper layer and the lower layer of the inlet of the housing of the first right half, and the airflow in the housing is specifically: for the upper air flow, the upper inlet air flow (here, the inner circulating air inlet air flow) f1i_d enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_d will be divided into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1d from the left side of the first mixing damper 310d (the air flow direction is shown in dashed line in fig. 24A). The second air flow branch of the upper inlet air flow f1i_d will pass through said first air flow processing unit (heater) 120, in particular it will enter the fifth space V5 and then through the first air flow processing unit 120 into the third space sub-zone V3d and via the right side of the first mixing damper 310d into the first space sub-zone V1d (air flow direction as shown in dotted line in fig. 24A), in which first space sub-zone V1d the two air flow branches will mix and form an upper output air flow.

For the lower air flow, when fresh air is introduced, the lower inlet air flow (here fresh air inlet air flow) f2i_d enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower inlet air flow f2i_d will be split into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and directly enters the second space sub-zone V2d from the right side of the second mixing damper 320d from the sixth space V6 (the air flow direction shown in dashed lines in fig. 24A). The second air flow branch of the lower inlet air flow f2i_d will pass through the first air flow processing unit (heater) 120, in particular it will enter the sixth space V6, then through the first air flow processing unit 120 into the fourth space sub-zone V4d, finally from the left side of the second mixing damper 320d into the second space sub-zone V2d (the air flow direction as shown in dotted line in fig. 24A), in the second space sub-zone V2d the two air flow branches will mix and form the lower output air flow.

At this time, the first sub-damper 170d in the first position will be engaged with the first partition portion and guide the upper output airflow in the first space sub-area V1d and the lower output airflow in the second space sub-area V2d to form the output airflow fo_d together, and the output airflow fo_d flows out through the right half front ventilation sub-outlet 1821 d.

Referring to fig. 24B, when the heating, ventilation and/or air conditioning apparatus 100' is in the ventilation mode, the first sub-damper 170c in the second right half 1132 is now configured in the second position to fully close the right half rear foot-blowing outlet 162 c. The defogging sub-damper 191c will be in a fully closed position to fully close the defogging sub-outlet 181c, and the third sub-damper (here, as a front ventilation sub-damper) 172c is, for example, in an open position, and the specific opening position may be, for example, adjusted as actually needed to cause the right half rear ventilation sub-outlet 1822c to be opened at a desired opening.

At this time, the upper and lower layers of the housing inlet of the second right half are, for example, filled with fresh air, and the air flow in the housing is specifically: for the upper air flow, the upper inlet air flow (here fresh air inlet air flow) f1i_c enters, for example, from the inlet upper portion, first through the treatment of the second air flow treatment unit 130 (evaporator), after which the upper inlet air flow f1i_c will be split into two air flow branches, wherein the first air flow branch bypasses the first air flow treatment unit 120, enters the fifth space V5 and directly enters the first space sub-zone V1c from the left side of the first mixing damper 310c (the air flow direction is shown in dashed lines in fig. 24B). The second air flow branch of the upper inlet air flow f1i_c will pass through the first air flow processing unit (heater) 120, in particular, it will enter the fifth space V5, and then through the first air flow processing unit 120 into the third space sub-zone V3c and into the first space sub-zone V1c via the right side of the first mixing damper 310c (the air flow direction is shown in dotted line in fig. 24B). Thereafter, in the first sub-zone of space V1c, the two air flow branches will mix and form an upper output air flow (here fresh air output air flow) f1o_c.

For the lower air flow, when fresh air is introduced, the lower inlet air flow (here fresh air inlet air flow) f2i_c enters, for example, from the inlet lower portion, first it is processed by the second air flow processing unit 130 (evaporator), after which the lower inlet air flow f2i_c will be split into two air flow branches, wherein the first air flow branch bypasses the first air flow processing unit 120, enters the sixth space V6, and directly from the sixth space V6 from the right side of the second mixing damper 320c into the second space first sub-zone V2c-1 (the air flow direction shown in dashed lines in fig. 24B). The second air flow branch of the lower inlet air flow f2i—c will pass through the first air flow processing unit (heater) 120, in particular, it will enter the sixth space V6, then through the first air flow processing unit 120 into the fourth space sub-area V4c, and finally from the left side of the second mixing damper 320c into the second space first sub-area V2c-1 (the air flow direction is shown by dotted lines in fig. 24B). Thereafter, in the first sub-zone V2c-1 of the second space, the two gas flow branches will mix and form the lower output gas flow F2o_c.

And at this time, the second sub-damper 171c in the fully closed position will be engaged with the first partition and the laterally extending wall to partition the second space first sub-zone V2c-1 and the second space second sub-zone V2c-2, on the one hand, guide the upper output air flow f1o_c in the first space sub-zone V1c to the second space second sub-zone V2c-2 and output the upper output air flow f1o_c through the right half front ventilation sub-outlet 1821 c; on the other hand, the lower output air flow f2o_c is caused to flow only in the second space first sub-zone V2c-1 and is output via the right half rear ventilation sub-outlet 1822 c.
