Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
As shown in fig. 1 to 5, a preferred embodiment of the present invention is shown.
The air conditioner indoor unit may be a cabinet air conditioner, an air conditioner hanging unit or an air conditioner ceiling unit 100, which includes a first air guide port 111 and a second air guide port 121, where the first air guide port 111 and the second air guide port 121 are both used for guiding in or guiding out air flow to the air conditioner indoor unit. When the first air guide port 111 guides the ambient air flow (refers to the air flow outside the air conditioning indoor unit) into the air conditioning indoor unit, the ambient air guided into the air conditioning indoor unit flows through the heat exchange component 150 of the air conditioning indoor unit to exchange heat and then is guided out of the air conditioning indoor unit through the second air guide port 121; when the second air guide opening 121 guides the ambient air flow into the air conditioning indoor unit, the ambient air guided into the air conditioning indoor unit flows through the heat exchange component 150 of the air conditioning indoor unit, exchanges heat, and is guided out of the air conditioning indoor unit through the first air guide opening 111. In other words, when the first air guide 111 is the air inlet of the indoor unit of the air conditioner, the second air guide 121 is the air outlet of the indoor unit of the air conditioner; when the first air guide 111 is an air outlet of the air conditioner indoor unit, the second air guide 121 is an air inlet of the air conditioner indoor unit. In particular, the vertical height of the second air guide hole 121 is lower than the vertical height of the first air guide hole 111.
The air conditioner indoor unit is also provided with an air supply device, the air supply device is provided with a first working state and a second working state, the air supply device is configured to guide out the heat exchange air flow of the air conditioner indoor unit through the first air guide hole 111 in the first working state, and guide out the heat exchange air flow of the air conditioner indoor unit through the second air guide hole 121 in the second working state. That is, whether the first air guide 111 and the second air guide 121 are the air inlet or the air outlet is determined by the working state of the air supply device. When the air supply device is in the first working state, the first air guide opening 111 is an air outlet, and the second air guide opening 121 is an air inlet; when the air supply device is in the second working state, the first air guide opening 111 is an air inlet, and the second air guide opening 121 is an air outlet.
Specifically, in order to make the air conditioner have higher heat exchange efficiency, the air supply device is in the first working state when the air conditioner is in the refrigeration mode, and is in the second working state when the air conditioner is in the heating mode. Like this, when the air conditioner is refrigerated, derive cold wind by the higher first wind guide 111 of vertical height, because the hot air in the environment easily suspends in the higher position of vertical height, so let cold wind blow to the eminence and can make cold wind more easily carry out the heat exchange with the hot air in the environment to let the heat exchange of cold wind more abundant, the refrigeration effect is better. When the air conditioner heats, the second air guide opening 121 with lower vertical height guides hot air, and cold air in the environment is easy to sink into the part with lower vertical height, so that the part with lower hot air direction is blown to enable the hot air to exchange heat with the cold air in the environment more easily, thereby enabling the heat exchange of the hot air to be more sufficient and the heating effect to be better.
In this embodiment, in order to make the experience effect of the user better, when the air conditioner is in the refrigeration mode and the heating mode, the air supply device is in the first working state or in the second working state, and when the air supply device is in the first working state, both cold air and hot air are sprayed out from the part with lower vertical height, and the hot air and the cold air can be blown to the user more quickly, so that the user can get warm or cool quickly; when the first working state is the second working state, the direct blowing of the user can be avoided, and the overheating or cold of the user can be prevented. The specific working state of the air supply device is determined according to the actual requirements of users. In one embodiment, the operation state of the air supply device may be set corresponding to the operation mode of the indoor unit of the air conditioner. Namely, when a user selects the working mode of the air conditioner as an energy-saving mode, the air supply device defaults to a first working state when the air conditioner refrigerates, and the air supply device defaults to a second working state when the air conditioner heats, so that the heat exchange efficiency of the heat exchange airflow blown out by the air conditioner is higher, and the energy is saved. When the user selects the working mode of the air conditioner as a comfortable mode, the air supply device defaults to a first working state when the air conditioner refrigerates and heats, and the direct blowing of heat exchange air flow to the user is avoided.
In one embodiment, in order to prevent the air flows ejected from the first air guide port 111 and the second air guide port 121 of the air conditioning indoor unit from affecting each other, the heat exchange air flow in the air conditioning indoor unit may be ejected laterally from the first air guide port 111. Specifically, the heat exchange air flow in the indoor unit of the air conditioner may be ejected horizontally or obliquely upward or obliquely downward at a certain angle, so that when the first air guide opening 111 is an air outlet, the heat exchange air flow ejected in the first air guide opening 111 is not easy to flow back into the second air guide opening 121 to form a short circuit. In another embodiment, when the second air guide opening 121 is an air outlet, the heat exchange air flow of the indoor unit of the air conditioner can be further vertically ejected downwards out of the second air guide opening 121, so that the air flow ejected from the second air guide opening 121 is not easy to flow back to the first air guide opening 111.
In order to enable the air conditioning indoor unit to conveniently and laterally jet out air flow, in one embodiment, the air conditioning indoor unit may be the ceiling unit 100. The suspended ceiling machine 100 may be disposed at a ceiling of a room, and has a space around the space in the lateral direction, so that the air flow ejected from the first air guide 111 is not easy to blow to the wall of the room, and thus the air flow ejected from the first air guide 111 can have a longer lift.
Specifically, the ceiling machine 100 includes a bottom wall 120 and a side wall 110 extending vertically upward along an outer edge of the bottom wall 120, where an upper end edge of the side wall 110 is connected with a top wall opposite to the bottom wall 120, and the top wall may be disposed flush with a lower surface of the indoor ceiling, so that the top wall is embedded in the ceiling. The first air guide 111 is disposed around the side wall 110, so that the air flow ejected from the first air guide 111 can be dispersed around the ceiling machine 100. Specifically, the first air guide 111 may be one opening on the side wall 110, or may be a plurality of openings on the side wall 110, and when the side wall 110 has a plurality of openings, the plurality of openings of the first air guide 111 may be arranged at equal intervals. The second air guide 121 is disposed on the bottom wall 120, and may specifically be disposed at a central position of the bottom wall 120, so that the air flow may be vertically and downwardly ejected from the second air guide 121.
When the indoor unit of the air conditioner is the ceiling machine 100, in one embodiment, the illuminating lamp 123 can be further arranged on the bottom wall 120, and the illuminating lamp 123 is used for illuminating the outside of the ceiling machine 100, so that the ceiling machine 100 of the air conditioner can be used as a ceiling lamp, the problem that the indoor ceiling machine 100 of the air conditioner and the illuminating lamp 123 are easy to generate position interference is solved, the space of the ceiling is saved, and the cost is saved. Meanwhile, since the second air guide opening 121 is arranged on the side wall 110 of the ceiling machine 100, the opening area on the bottom wall 120 of the ceiling machine 100 can be reduced, and the lighting lamp 123 can be arranged in a larger space on the bottom wall 120, so that the whole volume of the ceiling machine 100 can be reduced.
In order to enable the first air guide 111 to spray the air flow outwards towards any angle in the horizontal plane, the bottom wall 120 and the top wall can be circular, the side wall 110 is circular, and the plurality of openings arranged on the side wall 110 are arranged in a circular array. In particular, when the suspended ceiling machine 100 is a cylinder, three posts may be connected to the top wall for positioning, and the three posts may be positioned in a manner that saves material and prevents the suspended ceiling machine 100 from being positioned excessively with respect to a structure in which the suspended ceiling machine 100 is a rectangular parallelepiped and is positioned by four posts.
The first air guide structure 112 is disposed at the first air guide 111, and the first air guide structure 112 is used for guiding the air flow ejected from the first air guide 111 and changing the opening size of the first air guide 111. To facilitate maintenance of the suspended ceiling machine 100, in one embodiment, a first end of the first air guiding structure 112 of the suspended ceiling machine 100 is hinged to the side wall 110 of the suspended ceiling machine 100, and a second end opposite to the first end is clamped to the side wall 110. As shown in fig. 3, when maintenance is needed, the clamping end of the first air guiding structure 112 is opened, and the first air guiding structure 112 is rotated around the hinge end thereof, so that the first air guiding structure 112 can be opened, thereby facilitating cleaning and maintenance inspection of the interior of the suspended ceiling machine 100. Because the first air guiding structure 112 is opened transversely, when the first air guiding structure 112 is opened, no dust falls onto the operator, so that the maintenance process is more convenient. Specifically, the first air guiding structure 112 may be in a louver shape, which has a plurality of first air guiding strips 1121 disposed parallel to each other, and the plurality of first air guiding strips 1121 change the size of the first air guiding opening 111 by rotating around a central axis parallel to the length direction thereof. And, when the first air guide strip 1121 rotates, it may also guide the air flow guided out in the first air guide hole 111. In particular, when the first air guide 111 has a plurality of openings, the same number of first air guide structures 112 as the number of openings may be correspondingly provided, and each first air guide structure 112 is installed and arranged corresponding to one opening.
The second air guide opening 121 is provided with a second air guide structure 122, and the second air guide structure 122 is used for guiding air flow sprayed out of the second air guide opening 121 and changing the opening size of the second air guide opening 121. Specifically, the second air guiding structure 122 may also be in a shutter shape, and has a plurality of second air guiding strips disposed parallel to each other, and the plurality of second air guiding strips rotate around a central axis parallel to the length direction thereof to change the size of the second air guiding opening 121. And, when the second wind guide bar rotates, it may also guide the air flow guided out in the second wind guide hole 121.
The first air guiding strip 1121 and the second air guiding strip may be driven by a driving device, and the driving device may specifically be a stepper motor, so that the user controls the stepper motor to rotate the first air guiding strip 1121 or the second air guiding strip to a position adapted to the air outlet parameter by adjusting the air outlet parameter.
When the air supply device is in the first working state, the first air guide 111 is an air outlet, the second air guide 121 is an air inlet, and in order to prevent the air intake of the suspended ceiling machine 100 from being affected by the second air guide structure 122, at this time, the second air guide strip of the second air guide structure 122 can rotate to the position where the second air guide 121 is maximum, so that the air intake of the second air guide 121 is maximum, and the stepper motor drives the first air guide strip 1121 to rotate to a suitable position according to the required air outlet.
When the air supply device is in the second working state, the second air guide opening 121 is an air outlet, the first air guide opening 111 is an air inlet, and in order to prevent the air intake of the suspended ceiling machine 100 from being affected by the first air guide structure 112, at this time, the first air guide strip 1121 of the first air guide structure 112 may rotate to a position where the first air guide opening 111 is maximum, so that the air intake of the first air guide opening 111 is maximum, and the stepper motor drives the second air guide strip to rotate to a suitable position according to the required air outlet.
In a specific embodiment, the supporting members 170 are disposed between the top wall and the bottom wall 120 of the suspended ceiling machine 100, specifically, the number of the supporting members 170 may be three, the top wall of the suspended ceiling machine 100 is connected to the upper end of the supporting members 170, the bottom wall 120 is connected to the lower end of the supporting members 170, and the supporting members are used for limiting the space between the top wall and the bottom wall 120. Meanwhile, a first air guide opening 111 is defined between the support members 170, and the first air guide structure 112 is further disposed between every two support members 170, one end of the first air guide structure 112 is hinged to one of the support members 170, and the other end is clamped to the other adjacent support member 170. The support member 170 may also be used to connect the struts used to hoist the suspended ceiling such that the overall weight of the suspended ceiling is transferred from the struts to the support member 170, and in particular, the support member 170 may be made of a material having a relatively high strength and rigidity to prevent deformation under force.
Because the existing four-side embedded ceiling machine is mostly applied to commercial occasions such as markets and office buildings, the indoor unit of the household air conditioner is mostly a cabinet air-conditioner air duct machine and the like, the structural design of the three supporting components 170 of the ceiling machine 100 in the embodiment can simultaneously replace various products (or the commercial four-side embedded machine) of the existing household air conditioner indoor unit, and the purpose of adjusting indoor air in an energy-saving, efficient and comfortable manner is achieved by adopting the ceiling mode placed in the closed space.
In order to achieve the purpose of changing the air supply direction in the suspended ceiling machine 100, in one specific embodiment, the air supply device may include a first fan and a second fan, where the first fan and the second fan blow air to the first air guide opening 111 and the second air guide opening 121 in a one-to-one correspondence manner, in a first working state, the first fan blowing air to the first air guide opening 111 is turned on, and in a second working state, the second fan blowing air to the second air guide opening 121 is turned on. In another specific embodiment, only one axial flow fan 140 may be provided, and the heat exchange air flow in the air conditioning indoor unit is led out from the first air guiding port 111 when the axial flow fan 140 rotates forward, and the heat exchange air flow in the air conditioning indoor unit is led out from the second air guiding port 121 when the axial flow fan 140 rotates backward (note that the specific rotation directions of the forward rotation and the backward rotation of the axial flow fan 140 are not limited above, and the "forward rotation" and the "backward rotation" merely indicate two opposite rotation directions of the axial flow fan 140). When only one axial flow fan 140 is provided, the direction of the air flow generated after the axial flow fan 140 is turned on can be changed by turning the orientation position of the axial flow fan 140 through a mechanical structure. In one embodiment, some mechanical structure may be further provided so that the blades of the axial flow fan 140 may be rotated, and the flow direction of the air flow after the axial flow fan 140 is turned on may be changed by rotating the blades of the axial flow fan 140 by a certain angle.
When the air supply device has two fans, the first fan is preferably an axial flow fan 140 and the second fan is preferably a centrifugal fan 130. The centrifugal fan 130 is used for spraying the heat exchange air flow in the suspended ceiling machine 100 through the first air guide opening 111, and the axial flow fan 140 is used for spraying the heat exchange air flow in the suspended ceiling machine 100 through the second air guide opening 121. The axial flow fan 140 can better achieve the air supply purpose of spraying the air flow in the vertical downward direction, and the centrifugal fan 130 can better achieve the air supply purpose of spraying the air flow in the circumferential direction into the first air guide opening 111.
The ceiling fan 100 further includes a heat exchange component 150, where the heat exchange component 150 is used for exchanging heat with air entering the ceiling fan 100, when the fan injecting air flow to the outside of the first air guide port 111 is a centrifugal fan 130, in order to save the internal space of the ceiling fan 100, in one embodiment, the center of the impeller 131 of the centrifugal fan 130 has a cavity with a downward opening, the heat exchange component 150 is disposed in the cavity, and the axial fan 140 is disposed below the heat exchange component 150. Such a positional arrangement can make good use of the space inside the impeller 131 of the centrifugal fan 130. Specifically, in order to facilitate the air flow inside the suspended ceiling machine 100 to be able to exchange heat with the heat exchange member 150 sufficiently, the heat exchange member 150 may have a circular ring shape, and the central axis thereof is parallel to the central axis of the impeller 131, so that the air flow generated by the axial flow fan 140 passes through the heat exchange member 150 in a direction parallel to the central axis of the heat exchange member 150, so that the ambient air can exchange heat with the heat exchange member 150 sufficiently. In order to prevent water condensed on the heat exchange member 150 from leaking down onto the axial flow fan 140, the diameter of the heat exchange member 150 may be made larger than the diameter of the blades of the axial flow fan 140, and the blades of the axial flow fan 140 may be entirely located at the center of the heat exchange member 150. In order to remove moisture generated on the heat exchange member 150, an annular water pan 160 may be provided under the heat exchange member 150. The center of the annular water receiving tray 160 is provided with a center hole, and the center hole is arranged corresponding to the second air guide opening 121 and is used for guiding out air flow. The annular water pan 160 is provided with an annular groove extending around the central hole, and the heat exchange component 150 is embedded in the annular groove, so that moisture generated by the heat exchange component 150 falls into the annular groove, and water stored in the annular groove is pumped away by using other drainage devices, so that the moisture in the suspended ceiling machine 100 can be effectively prevented from leaking. Particularly, when the illumination lamp 123 is provided on the bottom wall 120, the water pan 160 can also effectively protect the illumination lamp 123 on the bottom wall 120.
In order to prevent dust or other foreign matters in the environment from entering the suspended ceiling machine 100, a filter screen may be disposed at the air inlet of the suspended ceiling machine 100, and since the first air guide 111 and the second air guide 121 may be both used as the air inlet of the suspended ceiling machine 100, the filter screen may be disposed at the first air guide 111 and the second air guide 121. Since the filter screen is disposed at the air outlet of the suspended ceiling machine 100, the air outlet of the suspended ceiling machine 100 is not smooth enough, when the first air guide opening 111 is the air outlet, the filter screen may be disposed at the second air guide opening 121, and no filter screen is disposed at the first air guide opening 111; when the second air guide opening 121 is an air outlet, the first air guide opening 111 is provided with a filter screen, and the second air guide opening 121 is not provided with a filter screen.
For the air conditioner indoor unit in any of the above embodiments, as shown in fig. 6 to 7, the present invention further provides an air supply control method for the air conditioner indoor unit:
s110: acquiring a working mode of an air conditioner indoor unit;
s130: determining the air supply direction in the air conditioner indoor unit according to the working mode;
s150: the air supply device is controlled to supply air in the air supply direction, so that the heat exchange air flow in the indoor unit of the air conditioner is sprayed out by the first air guide port 111 or the second air guide port 121.
That is, in different operation modes of the air conditioning indoor unit, the air supply directions in the air conditioning indoor unit are different, and the air supply directions mentioned above specifically refer to whether the heat exchange air flow in the air conditioning indoor unit is ejected toward the first air guide port 111 or the second air guide port 121. When the heat exchange air flow is sprayed out towards the first air guide opening 111, the first air guide opening 111 is an air outlet, and the second air guide opening 121 is an air inlet. When the heat exchange air flow is sprayed out towards the second air guide opening 121, the second air guide opening 121 is an air outlet, and the first air guide opening 111 is an air inlet. Specifically, the working modes of the air conditioner indoor unit may include a heating mode and a cooling mode, and after determining the working mode of the air conditioner indoor unit, controlling the air supply device to supply air in the determined air supply direction specifically includes:
s131: when the operation mode is the cooling mode, the air supply direction is a direction in which the heat exchange air flow in the air conditioning indoor unit is ejected toward the first air guide port 111.
S133: when the operation mode is the heating mode, the air supply direction is a direction in which the heat exchange air flow in the air conditioning indoor unit is ejected toward the second air guide port 121.
That is, the first air guide 111 is an air inlet of the air conditioner indoor unit in the heating mode, and the second air guide 121 is an air outlet of the air conditioner indoor unit. In the cooling mode, the first air guide opening 111 is an air outlet of the air conditioning indoor unit, and the second air guide opening 121 is an air inlet of the air conditioning indoor unit. As described above, the above air outlet mode can make the heat exchange efficiency of the indoor unit of the air conditioner higher.
In order to enable the air outlet size in the first air guide 111 and the second air guide 121 to be adjusted, in an embodiment, the size of the first air guide 111 and/or the size of the second air guide 121 may be made variable. Specifically, the first air guiding structure 112 may be disposed at the first air guiding opening 111, and the second air guiding structure 122 may be disposed at the second air guiding opening 121, where the first air guiding structure 112 and the second air guiding structure 122 are described in detail above and are not described herein.
Because the larger the air inlet of the air conditioner indoor unit is, the smoother the air inlet is, in one embodiment, the air supply control method of the air conditioner indoor unit further comprises:
s151: when the working mode of the indoor unit of the air conditioner is a heating mode, the first air guide mechanism is regulated to enable the opening of the first air guide opening 111 serving as the air inlet to be maximum;
s153: when the operation mode of the indoor unit of the air conditioner is the cooling mode, the second air guiding mechanism is adjusted to maximize the opening of the second air guiding opening 121 serving as the air inlet.
The control method can keep the air inlet of the air conditioner indoor unit smoother.
In one embodiment, the first air guide 111 and the second air guide 121 are provided with a filter for filtering dust or foreign matters in the air. The filter corresponding to the first air guide 111 may block or open the first air guide 111, and the filter corresponding to the second air guide 121 may block or open the second air guide 121. After the filter screen is arranged, the air supply control method of the air conditioner indoor unit further comprises the following steps:
s171: when the working mode is a heating mode, the filter screen corresponding to the first air guide opening 111 is made to shield the first air guide opening 111, and the filter screen corresponding to the second air guide opening 121 is made to open the second air guide opening 121;
s173: when the operation mode is the cooling mode, the filter screen corresponding to the second air guide opening 121 is made to shield the second air guide opening 121, and the filter screen corresponding to the first air guide opening 111 is made to open the first air guide opening 111.
That is, when the first air guide opening 111 is an air outlet, the filter screen at the first air guide opening 111 can be removed (i.e. the filter screen corresponding to the first air guide opening 111 is opened to open the first air guide opening 111), so that the air inlet of the indoor unit of the air conditioner is unobstructed; the filter screen at the second air guide opening 121 is reserved (i.e. the filter screen corresponding to the second air guide opening 121 covers the second air guide opening 121) so as to filter the air flow introduced into the second air guide opening 121. When the second air guide opening 121 is an air outlet, the filter screen at the second air guide opening 121 can be removed to ensure that the air inlet of the indoor unit of the air conditioner is smooth; the filter screen at the first air guide 111 is maintained to filter the air flow introduced into the first air guide 111. Specifically, the filter screen can be taken down manually or automatically. When the filter screen is automatically taken down, the filter screen can be connected with the driving device, and when the filter screen is required to be filtered, the driving device drives the filter screen to rotate to a position covering the first air guide opening 111 or the second air guide opening 121, and when the filter screen is required to be taken down, the driving device drives the filter screen to rotate to a position not shielding the first air guide opening 111 or the second air guide opening 121.
The specific air supply direction of the air supply device is as follows:
s191: when the air conditioner indoor unit is in a heating mode, the air supply device supplies air to the outside of the second air guide port 121;
s193: when the air conditioning indoor unit is in the cooling mode, the air blowing device blows air out of the first air guide port 111.
The air supply device may include two fans, which are in one-to-one correspondence to supply air to the outside of the first air guide port 111 and the second air guide port 121. The air supply device may also include only the axial flow fan 140, and the axial flow fan 140 changes the air supply direction by the positive and negative rotation of the impeller. The specific operation of providing two fans or only one axial flow fan 140 is described above, and will not be described here.
When the indoor unit of the air conditioner is the ceiling fan 100, the centrifugal fan 130 and the axial fan 140 may be provided to supply air, the centrifugal fan 130 is used for supplying air towards the outside of the first air guide opening 111, and the axial fan 140 is used for supplying air towards the outside of the second air guide opening 121. The heat exchanging element 150 in the ceiling fan 100 is provided inside the impeller of the centrifugal fan 130 so that the ambient air flow introduced into the air conditioning indoor unit can exchange heat sufficiently.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
