The water tray cover 6 of the present application will now be described with reference to figures 3, 4 and 12.
As shown in fig. 3, 4 and 12, the water-tray upper cover 6 is made of foam material or plastic material, and comprises a second body 61 and a plurality of side edges 62 formed by downward extending edges of the second body 61, when the water-tray upper cover is installed, the second body 61 covers the top of the heat exchanger 2, and the side edges 62 at least partially cover the outer side surfaces of the heat exchanger 2. Preferably, the side 62 of the water tray upper cover 6 can extend to completely cover the outer side of the heat exchanger 2. In this way, a relatively closed space is defined between the second body 61 of the water pan upper cover 6, the side edge 62, the outer side surface of the heat exchanger 2 and the side plate 12 of the housing. Referring to fig. 12, a triangular rib 621 is respectively disposed on inner side surfaces of two adjacent side edges 62 of the water pan 3 corresponding to the first corner 13, the triangular rib 621 has three air guide inclined surfaces 6211, wherein two air guide inclined surfaces 6211 are symmetrically disposed and respectively inclined to left and right sides of the side edge 62, and another air guide inclined surface 6211 is inclined upward after the water pan upper cover 6 is mounted, so that the air guide inclined surface 6211 can guide the air flow after heat exchange to the first air guide passage 51.
Through being refined into first bight 13 and second bight 14 with four bights to set up different induced air structure and lid piece to the bight of difference, make different bights form different induced air passageways, thereby successfully guide the air current after the heat transfer to corresponding bight air outlet 122 through different induced air passageways, guarantee the air-out effect of every bight air outlet 122. Specifically, since the two free ends of the heat exchanger 2 form a duct notch at the first corner 13, the air discharged by the fan cannot exchange heat with the heat exchanger 2 at the notch, and therefore, by providing the two first induced air channels 51 of the first corner 13 as S-shaped channels extending in the longitudinal direction of the side plate 12 and setting the inlet of the first induced air channel 51 higher than the outlet, the air flow after exchanging heat with the upper portion of the peripheral side of the heat exchanger 2 near the first corner 13 can enter the first induced air channel 51 and be discharged to the corner air outlet 122 through the S-shaped channels of the first induced air channel 51. And the air flow at the rest second corner 14 can exchange heat with the heat exchanger 2, so that the inlets of the two second induced air channels 52 arranged at the second corner 14 are directly arranged in the direction facing the heat exchanger 2, and the air flow near the second corner 14 and exchanging heat with the heat exchanger 2 can be directly introduced into the second induced air channels 52 and discharged to the corner air outlets 122 through the second induced air channels 52.
Furthermore, by arranging the air guide inclined plane 4121 on an inner side surface of the upper air guide groove 412 corresponding to the inlet of the first air guide channel 51, arranging the triangular ribs 621 on two adjacent side edges 62 of the water receiving tray upper cover 6 corresponding to the first corner portion 13, and arranging the air guide inclined plane 6211 on the triangular ribs 621, the air flow can be successfully guided to the inlet of the first air guide channel 51, so as to increase the air intake of the first air guide channel 51, further improve the air output of the corner air outlet 122, and avoid the air output of the corner air outlet 122 being smaller due to the formation of a piping notch at the first corner portion 13. Similarly, the air guide inclined surface 3321 is arranged on the inner side surface of the vertical bump 332, and the air guide inclined surface 3322 is arranged on the top surface of the vertical bump 332, so that the air flow after heat exchange can be guided to the inlet of the second induced air channel 52, the air intake of the second induced air channel 52 is increased, and the air output of the corner air outlet 122 is further increased.
By providing the air guide slope 4122 on one inner surface of the upper air guide groove 412 corresponding to the outlet of the first air guide duct 51, the air flow in the first air guide duct can be guided to be blown out obliquely downward after passing through the corner air outlet 122, and the air blowing effect of the corner air outlet 122 of the first corner portion 13 can be improved. Similarly, the air guide slope 341 provided at the air guide slit 34 and the air guide slope 4221 provided on the bottom surface of the protrusion 422 guide the air flow in the second air guide passage 52 to be blown obliquely downward after passing through the corner air outlet 122, thereby improving the air blowing effect of the corner air outlet 122 of the second corner 14.
Through forming first step face 35 on first induced air structure 32, first lid closes 41 and closes first induced air structure 32 through the fixed lid of first step face 35 on for first lid closes 41 can be firm and the card is arranged in between first induced air structure 32 and curb plate 12, avoids first induced air passageway 51 circumstances such as leaking out to take place. Similarly, by forming the second stepped surface 36 on the second air inducing structure 33, the second covering member 42 is fixedly covered on the second air inducing structure 33 through the second stepped surface 36, so that the second covering member 42 can be firmly covered and clamped between the second air inducing structure 33 and the side plate 12, and air leakage of the second air inducing channel 52 is avoided. The first avoiding groove 3221 is arranged on the outer side surface of the first air inducing structure 32, and the second avoiding groove 3323 is arranged on the outer side surface of the second air inducing structure 33, so that an avoiding space can be reserved for a motor of the air deflector 15, and the air conditioner can be assembled conveniently.
Through setting up water collector upper cover 6 to the lateral surface that heat exchanger 2 was sheltered from to the side 62 part of water collector upper cover 6 at least, make water collector 3 can form the barrier in heat exchanger 2 upper portion and outside, leak with the upper portion or the side upper portion that prevent the air current after the heat transfer and directly pass through heat exchanger 2 not through induced air passageway, thereby improve the intake of each induced air passageway, guarantee the air-out effect of bight air outlet 122.

Without departing from the principles of the present invention, those skilled in the art can adjust the setting manner described above so that the present invention can be applied to more specific application scenarios.
For example, in an alternative embodiment, although the above embodiment has been described with reference to two different corner wind-inducing structures and corner covering elements, the present application is not limited thereto, and in other possible embodiments, the positions of the two free ends of the heat exchanger 2 may be changed to make the four corners have the same structure, and in this case, the four corners may be arranged according to the arrangement of the second corner 14.
As another example, in another alternative embodiment, although the above embodiment describes the specific structures of the first induced air structure 32, the first cover element 41, the second induced air structure 33 and the second cover element 42 in great detail, this is not intended to limit the protection scope of the present application, and a person skilled in the art can adjust the above structures based on the principle of the present application as long as the adjustment can effectively stroke the first induced air channel 51 and the second induced air channel 52. For example, those skilled in the art may alter the cynical orientation of first inducer passageway 51 by altering the configuration of first inducer structure 32 and first closure element 41 so that the cynical orientation is angled with respect to side panel 12 to facilitate airflow. For another example, the arrangement of the wind guide inclined surfaces 4121 and 4122 in the upper wind guide groove 412 may be omitted by those skilled in the art, which does not affect the implementation of the present application. Similarly, those skilled in the art may adjust the specific shapes, installation positions, and the like of the second air guiding structure 33 and the second closing member 42, or omit the air guiding inclined surface 4221 provided on the protrusion 422 or the air guiding inclined surface 341 provided at the air guiding slit 34.
As another example, in another alternative embodiment, although the above embodiment is described in connection with the two corner air outlets 122 provided for each side plate 12, it is understood by those skilled in the art that the number of the corner air outlets 122 provided for each side plate 12 is not limited, and the number of the corner air outlets 122 may be provided as one or more, and in the case of changing the number, only the first inducing structure 32 and the first cover element 41 forming the first inducing channel 51, and the second inducing structure 33 and the second cover element 42 forming the second inducing channel 52 need to be adjusted accordingly.
Of course, the above alternative embodiments, and the alternative embodiments and the preferred embodiments can also be used in a cross-matching manner, so that a new embodiment is combined to be suitable for a more specific application scenario.
Moreover, those skilled in the art will appreciate that although some embodiments described herein include some features included in other embodiments, not others, combinations of features of different embodiments are meant to be within the scope of the invention and form different embodiments. For example, in the claims of the present invention, any of the claimed embodiments may be used in any combination.
Referring to fig. 15, a method for controlling outlet air of the embedded air conditioner according to the present application will be described. Fig. 15 is a main flow chart of an air outlet control method of an embedded air conditioner according to the present invention.
As shown in fig. 15, in order to solve the problem that the energy is wasted because the embedded air conditioner cannot control the air supply intensity based on the number of indoor persons, on the basis of the structure of the embedded air conditioner, the present application further provides an air outlet control method of the embedded air conditioner, which includes:
s101, acquiring the number of personnel in the indoor environment in the running process of the embedded air conditioner; for example, a human body detection component, such as an infrared sensor, a camera, a radar sensor, or the like, is installed on a bottom plate of an embedded air conditioner (hereinafter, referred to as an air conditioner), and the air conditioner can obtain the number of human bodies in a current room based on the human body detection component. The principle of the human body detecting part for detecting the number of human bodies is common knowledge in the art, and is not described herein again. Of course, the human body detecting member may be provided at any possible position other than the bottom plate, such as a ceiling of an indoor space or a wall.
S103, judging whether people exist indoors or not based on the number of the people; for example, after the number of indoor human bodies is acquired, whether the number of human bodies is zero is judged, and if yes, it is judged that no human exists indoors; otherwise, if the number of the human bodies is not zero, the indoor existence of people is judged.
S105, when the judgment result is that no person is in the room and the duration time of the nobody state is greater than or equal to a preset time threshold value, controlling the embedded air conditioner to operate in an energy-saving mode; for example, the preset time threshold may be 30min, when it is determined that there is no person in the room, the duration of the nobody state in the room is counted, and when the duration of the nobody state is greater than or equal to 30min, the embedded air conditioner is controlled to operate the energy saving mode. Certainly, the preset time threshold is not a constant value, and those skilled in the art can adjust the preset time threshold, so that the air-out control method is suitable for more specific application scenarios. For example, the preset time threshold can be any value within 2min-50 min.
And S107, when the embedded air conditioner runs in the energy-saving mode, controlling the opening and closing of the air deflector and the rotating speed of the fan based on the duration of the unattended state. For example, when the embedded air conditioner operates in the energy-saving mode, if the duration time of the nobody state is less than 1 hour, part of the air deflectors are controlled to be closed, and the fan reduces the rotating speed to operate; on the basis, if the duration time of the nobody state exceeds 1 hour, all the air deflectors are further controlled to be closed, and the rotating speed of the fan is further reduced.
According to the above description, the embedded air conditioner is controlled to enter the energy-saving mode when the duration time of the indoor nobody state and the nobody state is greater than or equal to the preset time threshold value, the air outlet control method can reasonably adjust the air outlet intensity based on the number of indoor persons, reduce the energy consumption of the indoor nobody air conditioner, and avoid energy waste. Further, when the embedded air conditioner operates in the energy-saving mode, the opening and closing of the air deflector and the rotating speed of the fan are controlled based on the duration time of the unattended state, and the air outlet control method can also give consideration to the operation effect and the energy consumption of the air conditioner.
A preferred embodiment of the present application will now be described with reference to fig. 16. Fig. 16 is a flowchart illustrating an outlet air control method of an embedded air conditioner according to a preferred embodiment of the present invention.
As shown in fig. 16, in a preferred embodiment, the method for controlling outlet air of an embedded air conditioner includes the following steps:
firstly, executing step S201, and acquiring the number of personnel in the indoor environment in the running process of the embedded air conditioner; for example, the number of people in the indoor environment is acquired by a human body inspection part such as an infrared sensor, a camera, or a radar sensor provided on the floor.
Next, step S203 is executed to determine whether there is a person in the room based on the number of persons in the indoor environment; if not, executing step S205, and further determining whether the duration time of the nobody state is greater than or equal to the preset time threshold; otherwise, if yes, step S215 is executed to further determine whether the current operation mode of the air conditioner is the normal air supply mode.
When step S205 is executed, if the result of the further determination is yes, that is, the duration time of the unattended state is greater than or equal to the preset time threshold, step S207 is executed, and the air conditioner is controlled to operate the energy saving mode, that is, the opening and closing of the air deflector and the rotation speed of the fan are controlled based on the duration time of the unattended state; otherwise, if the judgment result is no, that is, the duration time of each person state is less than the preset time threshold, the air conditioner is controlled to return to the step S201, and the number of persons in the indoor environment is obtained again.
As will be understood by those skilled in the art, when the duration of the unattended state is greater than or equal to the preset time threshold, it is proved that there is a period of time when the indoor is in the unattended state, and no matter what operation mode the air conditioner is in before, if the air conditioner continues to operate in this mode, the problem of energy waste is caused. At the moment, the opening and closing of the air deflector and the rotating speed of the fan are controlled based on the duration time of the unattended state, so that not only can energy consumption be saved, but also the operation effect of the air conditioner can be considered. On the contrary, if the duration time of the unattended state is less than the preset time threshold, it is proved that the time of the unattended state in the room is too short, and at the moment, the air conditioner is controlled to operate in the energy-saving mode, so that frequent starting and stopping and mode switching of the air conditioner can be caused, and the control stability and the service life of the air conditioner are not facilitated. At this time, the air conditioner is controlled to return to step S201 to reacquire the number of persons in the room.
The preset time threshold is preferably 30min in the present application, and of course, a person skilled in the art can adjust the preset time threshold based on an actual application scenario. For example, when the indoor environment space is large, the personnel flow more frequently, and at this time, the preset time threshold value can be increased appropriately so as to avoid the frequent switching of the operation mode of the air conditioner; when the indoor environment space is small, personnel flow less, and the preset time threshold value can be properly reduced, so that the mode switching of the air conditioner is more timely.
It should be further explained that, in the present application, the operation modes of the air conditioner at least include a normal blowing mode and an energy saving mode, and the normal blowing mode is applied to the indoor situation where there is a person, and the normal blowing mode adjusts the indoor environment temperature by controlling the opening and closing of the air deflector and the rotation speed of the fan, so as to create a comfortable environment for indoor personnel. And the energy-saving mode corresponds to the indoor unmanned condition, and reduces the running energy consumption of the air conditioner by controlling the closing of part or all of the air deflectors and greatly reducing the rotating speed of the fan. Generally speaking, the operation energy consumption of the normal air supply mode is larger than that of the energy-saving mode. The present embodiment will be described by taking as an example that the operation mode of the air conditioner includes only the normal air blowing mode and the energy saving mode.
In a preferred embodiment, step S207 further includes:
s209, if the duration time of the nobody state is less than a first time threshold value, controlling part of air deflectors to be closed, and controlling the fan to operate at a first preset rotating speed.
S211, if the duration time of the no-person state is greater than or equal to the first time threshold and smaller than the second time threshold, controlling all the air deflectors to be closed, and controlling the fan to operate at a second preset rotating speed.
S213, if the duration time of the unattended state is greater than or equal to a second time threshold value, controlling the embedded air conditioner to stop; the second time threshold is greater than the first time threshold, and the second preset rotating speed is less than the first preset rotating speed.
For example, the first time threshold may be 1h, the second time threshold may be 2h, the first preset rotation speed may be 1/4n, and the second preset rotation speed may be 1/8n, where n is a rated rotation speed or a maximum rotation speed of the fan. When the duration time of the indoor environment in the unmanned state is less than 1h, part of the air deflectors are controlled to be closed, if two opposite air deflectors are controlled to be closed, the rotating speed of the fan is reduced to 1/4 of the rated rotating speed or the highest rotating speed, the air conditioner is in the weak air supply state of the double air deflectors, the air conditioner can still have certain peak intensity on the basis of reducing the running energy consumption of the air conditioner, and the stable indoor environment temperature is ensured. When the duration time of the indoor environment in the unmanned state is longer than 1h and shorter than 2h, all air deflectors are controlled to be closed, the rotating speed of the fan is reduced to 1/8 of the rated rotating speed or the highest rotating speed, the air conditioner is in the air supply state of the air outlet at the corner, the running energy consumption of the air conditioner is further reduced, and meanwhile the stable temperature change is guaranteed. When the duration time of the indoor environment without people is longer than 2h, the indoor environment is proved to be in an unmanned state for a long time, and the air conditioner is controlled to stop at the moment so as to reduce energy consumption to the maximum extent.
Generally speaking, different air deflectors and fan controls are adopted when the duration time of the indoor unmanned state is different, so that the indoor temperature can be stably and slowly changed, and the situations that the air conditioner is frequently started and stopped and the indoor environment temperature fluctuates greatly due to the fact that a direct stopping control mode is adopted in the unmanned state are avoided.
Of course, the first time threshold, the second time threshold, the first preset rotation speed and the second preset rotation speed in the above specific examples are not exclusive, and those skilled in the art may make adjustments based on practical application scenarios, and such adjustments do not depart from the principles of the present application.
Referring to fig. 3, when the determination result in step S203 is that there is a person in the room, step S215 is executed to determine whether the current operation mode of the air conditioner is the normal air supply mode, for example, the current air supply mode is obtained by obtaining the rotation speed of the fan, the rotation angle of the driving motor of the air deflector, or the like, or the current air supply mode is obtained by reading the current operation state information. If the determination result is yes, that is, the current operation mode is the normal blowing mode, step S217 is executed to continue the operation in the normal mode. And under the normal air supply mode, the air guide plate is controlled to be fully opened, and the rotating speed of the fan is controlled based on the number of the personnel.
Specifically, in a preferred embodiment, step S217 further includes:
and S219, if the number of the persons is larger than or equal to the first person number threshold value, controlling the fan to operate at a third preset rotating speed.
And S221, if the number of the people is smaller than the first number threshold and larger than or equal to the second number threshold, controlling the fan to operate at a fourth preset rotating speed.
S223, if the number of people is smaller than a second number of people threshold value, controlling the fan to operate at a fifth preset rotating speed; and the third preset rotating speed, the fourth preset rotating speed and the fifth preset rotating speed are sequentially reduced.
For example, the first people number threshold may be 5, the second people number threshold may be 2, the third preset rotation speed may be n, the fourth preset rotation speed may be 3/4n, and the fifth preset rotation speed may be 1/2n, where n may also be a rated rotation speed or a maximum rotation speed of the fan. When the number of indoor personnel is more than or equal to 5 people, the number of the personnel is proved to be more at the moment, the air conditioner is required to provide higher air outlet strength, and the fan is controlled to operate at a rated rotating speed or the maximum rotating speed on the basis of controlling the air deflector to be fully opened, so that the air conditioner is in a powerful air supply state; when the number of indoor personnel is less than 5 and more than or equal to 2, the number of the personnel is reasonably small at the moment, the air outlet intensity of the air conditioner needs to be properly reduced, and the fan is controlled to operate at the rated rotating speed or 3/4 of the maximum rotating speed on the basis of controlling the air deflector to be fully opened at the moment, so that the air conditioner is in a stable air supply state; when the number of indoor personnel is less than 2 people, the number of the personnel is very small at the moment, the air outlet intensity of the air conditioner needs to be further reduced, and on the basis of controlling the air deflector to be fully opened at the moment, the air conditioner is in a soft air supply state only by controlling the fan to run at the rated rotating speed or 1/2 of the highest rotating speed.
Through the normal air supply mode of current operation of air conditioner and judge that the result is indoor when having the people, control embedded air conditioner and continue to operate normal air supply mode to further based on the rotational speed of indoor personnel quantity control fan, make the air-out intensity of embedded air conditioner can with indoor personnel quantity phase-match, guarantee the comfort level of indoor environment.
Continuing to refer to fig. 16, when the determination result in step S215 is negative, that is, when the air conditioner is currently in the energy-saving air supply mode, it is proved that the indoor environment is changed from the unattended state to the manned state, and the indoor environment temperature needs to be rapidly adjusted to a more comfortable temperature, at this time, step S223 is directly performed, that is, the air deflector is controlled to be fully opened, and the fan is controlled to operate at the rated rotation speed or the highest rotation speed, so as to rapidly adjust the low indoor environment temperature.
Through at the current energy-conserving mode of operation of air conditioner and judged result for indoor when having the people, control all aviation baffles and open entirely to control the fan and predetermine the rotational speed operation with the third and predetermine the time of predetermineeing, make embedded air conditioner can move with higher air-out intensity, thereby with faster speed regulation indoor ambient temperature, guarantee the comfort level of indoor environment.
Of course, the first person number threshold, the second person number threshold, the third preset rotation speed, the fourth preset rotation speed, and the fifth preset rotation speed in the above specific examples are not exclusive, and those skilled in the art may make adjustments based on practical application scenarios, and such adjustments do not depart from the principles of the present application.
