Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner and its control method. Background Technology

[0002] Currently, the air outlets of most vertical air conditioners on the market are less than two meters above the ground. Due to the sinking nature of cold air, this results in uneven air temperature vertically during cooling. If a higher temperature is set, the upper body feels warm, while a lower temperature makes the legs feel too cold. Existing vertical air conditioner indoor units are categorized by their airflow pattern into center-discharge and top-and-bottom-discharge types. Center-discharge units offer a better cooling experience in the middle, but the top doesn't circulate properly, resulting in higher air temperatures there. While top-and-bottom-discharge units improve the cooling experience in the upper and middle areas, their cooling effect is worse, leading to a less pleasant user experience when turned on. Therefore, existing vertical air conditioner indoor units fail to adequately meet user expectations. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide an air conditioner and its control method that overcome or at least partially solve the above problems. It can solve the problems of uneven air temperature in the vertical direction during the air conditioning cooling process in existing air conditioners, the user's experience of low temperature at the bottom and high temperature at the top, and the direct blowing of heat exchange air on the user, so as to make the air in the space more uniform and ultimately improve the user experience.

[0004] Specifically, the present invention provides a control method for an air conditioner. The air conditioner includes a vertical indoor unit, which includes a heat exchange section having a first air inlet for indoor air to flow in and a first air outlet for heat exchanged air to flow out.

[0005] A circulation section is provided for absorbing indoor air from above the heat exchange section and blowing the indoor air out.

[0006] The control method includes:

[0007] Get the temperature at the top and bottom of the air conditioner;

[0008] The airflow direction of the circulation section is adjusted according to the temperature difference between the upper temperature and the lower temperature of the air conditioner, and / or the airflow speed of the circulation section is adjusted according to the temperature difference between the upper temperature and the lower temperature of the air conditioner.

[0009] The air outlet direction includes at least a first air supply mode that supplies air to the first air inlet.

[0010] Optionally, the air outlet direction may also include a second air supply mode that supplies air to the first air outlet.

[0011] Optionally, adjusting the airflow direction of the circulation section based on the temperature difference between the upper and lower parts of the air conditioner includes:

[0012] When the temperature at the top of the air conditioner is greater than the temperature at the bottom of the air conditioner, the circulation unit executes the first air supply mode.

[0013] When the temperature at the top of the air conditioner is not greater than the temperature at the bottom of the air conditioner, the circulation unit executes the second air supply mode.

[0014] Optionally, adjusting the airflow speed of the circulation section based on the temperature difference between the upper and lower parts of the air conditioner includes:

[0015] When the temperature difference is greater than a first preset difference but not greater than a second preset difference, the air outlet velocity of the circulation section is a first wind speed; or

[0016] When the temperature difference is greater than a second preset difference but not greater than a third preset difference, the air outlet speed of the circulation section is the second air speed; or

[0017] When the temperature difference is greater than a third preset difference, the air outlet speed of the circulation section is the third wind speed;

[0018] The first preset difference is less than the second preset difference, and the second preset difference is less than the third preset difference;

[0019] The third wind speed is greater than the second wind speed, and the second wind speed is greater than the first wind speed.

[0020] Optionally, obtaining the upper temperature and lower temperature of the air conditioner includes:

[0021] The upper temperature and lower temperature of the air conditioner are obtained by using at least one of a temperature sensor and a temperature and humidity sensor.

[0022] Optionally, the control method for the air conditioner further includes:

[0023] Obtain user location;

[0024] The airflow direction of the first air outlet is controlled according to the user's location.

[0025] Optionally, the control method for the air conditioner further includes:

[0026] Obtain user location;

[0027] The air outlet direction of the circulation section when it executes the second air supply mode is controlled according to the user's location, so that the circulation section outlets air forward or outlets air downward.

[0028] Optionally, the circulation section is an air supply device.

[0029] Optionally, the circulation unit includes a housing and an air supply device.

[0030] Furthermore, the present invention also provides an air conditioner, comprising: a controller, the controller including a memory, a processor and an air conditioner executable program stored in the memory and running on the processor, and the processor implementing the control method described above when executing the air conditioner executable program.

[0031] In this invention, the air conditioner acquires the temperatures of its upper and lower sections. Based on the temperature difference between these two temperatures, the airflow direction of the circulation section is adjusted, and / or the airflow speed is adjusted based on the cooling rate. The circulation section has at least one airflow mode with an airflow direction, namely a first airflow mode that supplies air to the first air inlet. When the circulation section operates in the first airflow mode based on the temperature difference, some or all of the indoor air above the circulation section flows through the circulation section to the first air inlet and then into the heat exchange section. During this process, the indoor air entering the circulation section reduces the air density around the circulation section, causing the indoor air to accelerate its flow towards the circulation section and enter the heat exchange section through the air inlet for heat exchange. The circulation section operating in the first airflow mode not only allows the upper non-heat exchange air to participate in the heat exchange cycle but also allows the lower cold air to flow towards the upper part of the room, reducing the vertical temperature difference and significantly improving the air uniformity of the entire room, avoiding a "hot top, cold bottom" situation, and thus enhancing the user experience.

[0047] Figure 1 This is a flowchart of a control method for an air conditioner 10 according to an embodiment of the present invention, as follows: Figure 1 As shown, and refer to Figures 2 to 8 This invention provides a control method for an air conditioner 10. The air conditioner 10 includes a vertical indoor unit 100, which includes a heat exchange section 120 and a circulation section 110. The heat exchange section 120 has a first air inlet 122 for indoor air to flow in and a first air outlet 121 for heat exchanged air to flow out. The circulation section 110 is used to absorb indoor air from above the heat exchange section and blow the indoor air out.

[0048] Control methods include:

[0049] Step S11: Obtain the temperature of the upper part of the air conditioner and the temperature of the lower part of the air conditioner.

[0050] Step S12: Adjust the air outlet direction of the circulation section 110 and the air outlet speed of the circulation section 110 according to the temperature difference between the upper and lower temperatures of the air conditioner. The air outlet direction includes at least a first air supply mode that supplies air to the first air inlet 122.

[0051] like Figure 2 As shown, in some other embodiments of the present invention, the control method includes the following steps:

[0052] Step S21: Obtain the temperature of the upper part of the air conditioner and the temperature of the lower part of the air conditioner.

[0053] Step S22: Adjust the airflow speed of the circulation unit 110 based on the temperature difference between the upper and lower parts of the air conditioner.

[0054] like Figure 3 As shown, in some other embodiments of the present invention, the control method includes:

[0055] Step S31: Obtain the temperature of the upper part of the air conditioner and the temperature of the lower part of the air conditioner.

[0056] Step S32: Adjust the air outlet direction of the circulation section 110 according to the temperature difference between the upper temperature and the lower temperature of the air conditioner.

[0057] In these embodiments, the specific working process includes: the air conditioner 10 acquires the upper temperature and the lower temperature of the air conditioner, calculates the temperature difference between the upper and lower temperatures, adjusts the air outlet direction of the circulation section 110 according to the temperature difference, and / or adjusts the air outlet speed of the circulation section 110 according to the temperature difference. The circulation section 110 has at least one air supply mode with an air outlet direction, namely a first air supply mode that supplies air to the first air inlet 122. When the circulation section 110 operates in the first air supply mode according to the air conditioner temperature difference, the indoor air above the circulation section 110 flows part or all of its air through the circulation section 110 to the first air inlet 122, and then flows into the heat exchange section 120 through the first air inlet 122. After the indoor air flows into the heat exchange section 120 and undergoes heat exchange, it is blown into the room through the first air outlet 121. During this operation, indoor air enters the circulation section 110, causing the air density around the circulation section 110 to decrease. The indoor air accelerates its flow towards the circulation section 110 and enters the heat exchange section 120 through the first air inlet 122 for heat exchange.

[0058] In this embodiment, the circulation unit 110 increases the indoor airflow speed, thereby improving heat exchange efficiency. Furthermore, when the circulation unit 110 operates in the first air supply mode, it not only allows the upper non-heat exchange air to participate in the heat exchange cycle, but also allows the lower cool air to flow towards the upper part of the room, reducing the vertical temperature difference. This significantly improves the air uniformity of the entire room, preventing a "hot top, cold bottom" situation and thus enhancing the user experience.

[0059] like Figure 6 As shown, in some embodiments of the present invention, the air outlet direction further includes a second air supply mode that supplies air to the first air outlet.

[0060] In this embodiment, after the temperature difference between the upper part of the air conditioner and the lower part of the air conditioner reaches a set value, the air supply mode of the circulation section 110 is adjusted: the air supply direction changes from towards the first air inlet 122 during the cooling process to towards the front of the heat exchange section 120.

[0061] In this embodiment, because the temperature at the bottom of the air conditioner is close to that at the top, the indoor temperature tends to be uniform in the vertical direction. At this time, the indoor air that has reached the set temperature is blown through the circulation section 110 towards the front of the heat exchange section 120, achieving uniform airflow. Specifically, the cooled room temperature air (23°-26°) is blown onto the user, providing a comfortable and cool experience; furthermore, the airflow is further agitated by the upper circulating fan, making the indoor air more even and improving comfort.

[0062] like Figure 4 As shown, in some other embodiments of the present invention, the first air supply mode can be downward and rearward air supply, and the tilt angle can be any angle, preferably with the air outlet direction forming an angle of 45° with the horizontal line. Figure 6 As shown, the second air supply mode can be forward and downward air supply, and the tilt angle can be any angle, preferably the air outlet direction is at an angle of 45° with the horizontal line.

[0063] In some embodiments of the present invention, adjusting the airflow direction of the circulation unit 110 based on the temperature difference between the upper and lower temperatures of the air conditioner includes: when the upper temperature of the air conditioner is greater than the lower temperature, the circulation unit 110 executes a first airflow mode; when the upper temperature of the air conditioner is not greater than the lower temperature, the circulation unit 110 executes a second airflow mode.

[0064] In this embodiment, the temperature at the top of the air conditioner is greater than the temperature at the bottom, meaning there is a vertical temperature difference in the indoor air, causing people to feel "hot above and cold below." In this case, the indoor air at the top of the heat exchanger 120 needs to participate in the circulation and enter the heat exchanger 120 for heat exchange, thereby improving heat exchange efficiency and lowering the top temperature. Conversely, if the temperature at the top of the air conditioner is not greater than the temperature at the bottom, meaning the temperatures at the top and bottom are close, there is no vertical temperature difference in the indoor air, and people will not feel "cold above and hot below." In this case, the circulation unit 110 executes a second air supply mode to even out the airflow from the first air outlet 121 and change the direction of the airflow from the first air outlet 121 to avoid direct airflow onto the user.

[0065] In some embodiments of the present invention, adjusting the air outlet speed of the circulation section 110 according to the temperature difference between the upper temperature and the lower temperature of the air conditioner includes: the temperature difference includes at least a first difference and a second difference, the value of the first difference is less than the value of the second difference, and the air outlet speed of the circulation section determined according to the first difference is less than the air outlet speed of the circulation section determined according to the second difference.

[0066] The air velocity of the circulation section 110 affects the indoor airflow entering the heat exchange section 120 per unit time, thus affecting the heat exchange efficiency of the air conditioner 10. In this embodiment, when the temperature difference is large, the air velocity of the circulation section 110 is high, increasing the indoor airflow entering the heat exchange section 120 per unit time, thereby improving heat exchange efficiency and enhancing the heat exchange effect. Conversely, the opposite is also true. By determining the air velocity of the circulation section 110 based on the temperature difference, energy conservation is achieved while ensuring the heat exchange effect.

[0067] Furthermore, in some embodiments of the present invention, when the temperature difference is greater than a first preset difference but not greater than a second preset difference, the air outlet speed of the circulation section is a first wind speed. When the temperature difference is greater than a second preset difference but not greater than a third preset difference, the air outlet speed of the circulation section is a second wind speed. When the temperature difference is greater than a third preset difference, the air outlet speed of the circulation section is a third wind speed. The first preset difference is less than the second preset difference, and the second preset difference is less than the third preset difference. The third wind speed is greater than the second wind speed, and the second wind speed is greater than the first wind speed.

[0068] In this embodiment, the large temperature difference between the upper and lower parts of the air conditioner indicates a significant vertical temperature difference within the space. This means the airflow above the heat exchange section 120 is not fully participating in the overall indoor air circulation. In this case, increasing the airflow velocity of the circulation section 110 can improve the efficiency of the airflow above the heat exchange section 120 in participating in the overall indoor air circulation. Conversely, the airflow velocity of the circulation section 110 can be appropriately reduced. By adjusting the airflow velocity of the circulation section 110 based on the temperature difference between the lower part of the air conditioner and the set temperature, the working efficiency of the circulation section 110 is improved, saving energy. Further subdivision of the temperature difference allows for more precise adjustment.

[0069] In this embodiment, provided that the first preset value is less than the second preset value, and the second preset value is less than the third preset value, the first, second, and third preset values ​​can all be any values. Preferably, the first preset value is 1°C, the second preset value is 2°C, and the third preset value is 3°C. The first wind speed is the low wind speed of the circulating fan, the second wind speed is the medium wind speed of the circulating fan, and the third wind speed is the high wind speed of the circulating fan.

[0070] In some embodiments of the present invention, the control method of the air conditioner 10 further includes: obtaining the user's location; and controlling the air outlet direction of the first air outlet 121 according to the user's location.

[0071] In this embodiment, the air conditioner 10 obtains the user's location and adjusts the airflow direction of the first air outlet 121 according to the user's location, so that the airflow direction of the first air outlet 121 is directed towards the user, thereby quickly cooling the user and the surrounding area. Alternatively, the airflow direction of the first air outlet 121 is directed away from the user to avoid direct airflow causing discomfort to the user.

[0072] In some embodiments of the present invention, the control method of the air conditioner 10 further includes: obtaining the user's location; and controlling the air outlet direction of the circulation unit 110 when executing the second air supply mode according to the user's location, so that the circulation unit 110 outlets air forward.

[0073] In this embodiment, when the temperature at the top of the air conditioner is close to the temperature at the bottom, the airflow direction of the first air outlet is controlled to prevent it from blowing directly on the user. At this time, the circulation unit 110 executes the second air supply mode, blowing indoor air towards the user. This improves the temperature uniformity of the air blown towards the user, further enhancing the user experience. Of course, the circulation unit 110 can also be configured to blow air forward and downward.

[0074] In some embodiments of the present invention, when the circulation unit 110 executes the second air supply mode, it can move with people, avoid people, or swing freely.

[0075] In this embodiment, the airflow from the heat exchange section 120 is reduced to a very low speed when it avoids or faces a person, so as to achieve the effect of not blowing cold air directly on people and avoid discomfort caused to users by direct cold airflow. At the same time, the airflow from the circulation section 110 can follow people, avoid people, or oscillate freely. In particular, when oscillating freely, it can disperse the cold airflow, which helps to make the temperature of the user space drop evenly and provide users with a better air supply experience.

[0076] In some embodiments of the present invention, obtaining the upper temperature and the lower temperature of the air conditioner includes: obtaining the upper temperature and the lower temperature of the air conditioner by means of at least one of a temperature sensor and a temperature and humidity sensor.

[0077] In this embodiment, a temperature sensor and a humidity sensor are used to obtain the temperature at the top and bottom of the air conditioner, which is a simple and quick method.

[0078] In some embodiments of the present invention, the circulation section 110 is an air supply device 113. In this embodiment, the circulation section 110 does not have a housing, which simplifies the structure and saves costs.

[0079] In some embodiments of the present invention, the air supply device 113 is an axial flow fan. In this embodiment, using an axial flow fan as the air supply device 113 can reduce disturbance to the surrounding environment and reduce noise.

[0080] like Figure 8 As shown, the present invention also provides an air conditioner 10, including a heat exchange section 120, a circulation section 110, and a controller 130. The heat exchange section 120 has a first air inlet 122 for indoor air to flow in and a first air outlet 121 for heat exchanged air to flow out. The circulation section 110 is used to absorb indoor air from above the heat exchange section and blow the indoor air out. The controller 130 includes a memory 131, a processor 132, and an air conditioner 10 executable program stored in the memory 131 and running on the processor 132. When the processor 132 executes the air conditioner 10 executable program, it can implement the control method of any of the above embodiments.

[0081] In this embodiment, the vertical air conditioner indoor unit 100 has the advantages of improving indoor heat exchange efficiency and avoiding direct blowing of heat exchange air onto users. At the same time, the upper indoor air participates in the heat exchange cycle, which improves the problems of large vertical temperature difference and discomfort caused by direct blowing on users in existing air conditioners, thereby improving user comfort and experience.

[0082] In other embodiments of the present invention, the second air supply mode is to supply indoor air to the first air outlet 121. In this embodiment, the circulation unit 110 blows indoor air that has reached the set temperature into the first air outlet, which can also achieve the effect of uniform airflow.

[0083] Of course, in order to achieve a uniform airflow effect, in some other embodiments of the present invention, the second air supply mode is to supply indoor air to the front side of the first air outlet 121.

[0084] like Figure 4 and Figure 6 As shown, in some embodiments of the present invention, the circulation section 110 is movably provided such that the circulation section 110 has at least a first position and a second position. The circulation section 110 operates in a first air supply mode in the first position; the circulation section 110 operates in a second air supply mode in the second position.

[0085] In this embodiment, the circulation unit 110 is movable, and different air supply modes can be achieved by adjusting the circulation unit 110. When the circulation unit 110 is in the first position, the circulation unit 110 operates in the first air supply mode. When the circulation unit 110 is in the second position, the circulation unit 110 operates in the second air supply mode. Different air supply modes are adjusted by changing the position of the circulation unit 110.

[0086] In some embodiments of the present invention, the circulation section 110 is an air supply device 113. During the cooling process of the air conditioner, the air outlet of the air supply device 113 supplies air to the first air inlet 122. When the temperature difference between the upper part and the lower part of the air conditioner is less than a first preset value, the first air outlet of the air supply device 113 supplies air to the first air outlet 121. The air outlet direction of the air supply device 113 can be horizontal or inclined downward at any angle. When the air outlet direction of the air supply device 113 is inclined downward, it is preferable that the angle between the air outlet direction and the horizontal line is 45°.

[0087] In this embodiment, the circulation section 110 is simply the air supply device 113, which is simple in design and saves costs.

[0088] like Figures 4 to 7 As shown, in some embodiments of the present invention, the circulation section 110 includes a housing and an air supply device 113. The housing and the air supply device are integrally and movably disposed above the heat exchange section 120. The housing has a second air outlet 111 and a second air inlet 112. The second air inlet 112 is used to draw indoor air into the circulation section 110, and the second air outlet 111 is used to blow indoor air out of the circulation section 110. The air outlet area of ​​the air supply device 113 faces the second air outlet 111, and the air inlet area of ​​the air supply device 113 faces the second air inlet 112.

[0089] In the specific operation of this embodiment, the circulation section 110 rotates to change the orientation of the second air outlet 111 and the second air inlet 112. During the cooling process of the vertical air conditioner indoor unit 100, indoor air above the heat exchange section 120 that has not reached the set temperature enters the circulation section 110 through the second air inlet 112 and flows out of the circulation section 110 through the second air outlet 111, partially or entirely entering the heat exchange section 120 through the first air inlet 122 for heat exchange. After the vertical air conditioner indoor unit 100 reaches the set temperature, the circulation section 110 rotates, with the second air outlet 111 facing the first air outlet 121 and the second air inlet 112 facing the first air inlet 122. The second air outlet 111 blows the heated indoor air that has entered the circulation section 110 towards the first air outlet 121.

[0090] In this embodiment, the circulation section 110 is provided with a housing, which enhances the aesthetics of the design and also protects the air supply device 113.

[0091] Furthermore, in some embodiments of the present invention, the circulation section 110 is rotatably configured. In this embodiment, the rotatable configuration of the circulation section 110 allows for position adjustment by rotating it around an axis, thereby adjusting the air supply mode. This rotatable configuration makes position adjustment simple and controllable.

[0092] In some embodiments of the present invention, the circulation section 110 is rotatably arranged about a horizontal axis. In this embodiment, by rotating the circulation section 110, the air outlet area can be positioned in different directions, such as horizontally forward, horizontally backward, downward-forward, or downward-backward. This ultimately achieves airflow in different directions. In this embodiment, the horizontal arrangement of the rotation axis reduces space occupancy.

[0093] Of course, in some embodiments of the present invention, the circulation section 110 is rotatably arranged about a vertical axis.

[0094] In other embodiments of the invention, the circulation unit 110 includes a housing and an air supply device 113. The housing is fixedly disposed above the heat exchange unit 120, and the housing has a second air outlet 111 and a second air inlet 112. The air supply device 113 is movably disposed within the housing. The air supply device 113 operates in a first air supply mode when facing the second air outlet 111. The air supply device 113 operates in a second air supply mode when facing the second air inlet 112.

[0095] In this embodiment, during the cooling process of the indoor unit 100 of the vertical air conditioner, air enters through the second air inlet 112 and exits through the second air outlet 111. The air outlet area of ​​the air supply device 113 faces the second air inlet 112, blowing indoor air through the second air inlet 112 towards the first air inlet 122. When the temperature difference between the upper and lower parts of the air conditioner is less than a first preset value, air enters through the second air outlet 111 and exits through the second air inlet 112. The air outlet area of ​​the air supply device 113 faces the second air outlet 111, blowing indoor air through the second air outlet 111 towards the front of the heat exchange section 120. The circulation section 110 is equipped with a casing, which enhances the aesthetic design and also protects the air supply device 113.

[0096] Furthermore, in some embodiments of the present invention, the air supply device 113 is rotatably disposed within the housing. In this embodiment, the air supply device 113 is rotatably disposed, and the air supply mode is adjusted by rotating the air supply device 113 around an axis.

[0097] In some embodiments of the present invention, the air supply device 113 is rotatably arranged about a horizontal axis. In this embodiment, by rotating the air supply device 113, the air outlet area can be positioned horizontally forward, horizontally backward, downward-forward, or downward-backward, thus achieving air supply in different directions. In this embodiment, the horizontal arrangement of the rotation axis reduces space occupation.

[0098] Of course, in some embodiments of the present invention, the air supply device 113 is rotatably arranged about a vertical axis.

[0099] In some embodiments of the present invention, the air supply device 113 is an axial flow fan. In this embodiment, using an axial flow fan as the air supply device 113 can reduce noise.

[0100] In some embodiments of the present invention, a first air outlet 121 is disposed on the front side of the heat exchange section 120, the first air outlet 121 is elongated and extends in a vertical direction.

[0101] In this embodiment, the heat exchange air flows out from the first air outlet 121, which extends vertically, making the air outlet range of the vertical air conditioner indoor unit 100 larger and facilitating airflow diffusion. It also helps to reduce the temperature difference in the vertical direction.

[0102] In some embodiments of the present invention, an air guide device is provided at the first air outlet 121 for guiding air vertically.

[0103] In this embodiment, the air guide device guides the air upwards and downwards, and the air outlet direction is forward, forward and downward or diagonally upward, reducing upward air outlet and preventing the heat exchange air flowing out of the first air outlet 121 from directly entering the circulation section 110.

[0104] Of course, in some embodiments of the present invention, an air guiding device is provided at the first air outlet 121 for lateral air guiding. Lateral air sweeping expands the outlet angle of the heat exchange air and improves heat exchange efficiency.

[0105] In some embodiments of the present invention, the vertical air conditioner indoor unit 100 further includes at least two temperature detection devices. The circulation section 110 is provided with at least one temperature detection device to detect the temperature at the top of the air conditioner, and the lower end of the heat exchange section is provided with at least one temperature detection device to detect the temperature at the bottom of the air conditioner. Finally, the airflow mode of the air conditioner is controlled based on the temperature detected by the temperature detection devices at the top and bottom of the air conditioner.

[0106] In this embodiment, a temperature detection device is installed on the indoor unit 100 of the vertical air conditioner, and the temperature detected by the temperature detection device is fed back to the processor 132. The processor 132 processes the received information and executes different air supply modes according to a preset program. The temperature is easy to detect, and the air supply mode is controlled by the temperature, making the operation simple.

[0107] In some embodiments of the present invention, the temperature detection device is disposed above the circulation section 110. In this embodiment, the temperature detection device is disposed above the circulation section 110, which can measure the ambient temperature of the space above the circulation section 110, and the feedback data is more accurate.

[0108] In some embodiments of the present invention, in the first air supply mode, the opening direction of the second air outlet 111 faces rearward, and the first air inlet 122 is disposed below the second air outlet 111. Airflow around the first air inlet 122 flows into the heat exchange section 120 of the indoor unit of the air conditioner through the first air inlet 122. At this time, the gas density around the first air inlet 122 decreases, and the surrounding gas converges towards the first air inlet 122 and its surroundings. The indoor air flowing out of the second air outlet 111 flows towards the low-density area and enters the heat exchange section 120 through the first air inlet 122 for heat exchange. This facilitates the flow of indoor air from the second air outlet 111 into the heat exchange section 120 through the first air inlet 122.

[0109] In some embodiments of the present invention, the opening direction of the second air outlet 111 is downward and rearward, and the first air inlet 122 is disposed below the second air outlet 111.

[0110] In this embodiment, the second air outlet 111 is arranged facing downward and rearward. The indoor air flowing out of the second air outlet 111 has a downward movement trend, making it easier to flow into the heat exchange section 120 through the first air inlet 122.

[0111] Of course, in other embodiments of the present invention, the opening direction of the second air outlet 111 is downward, and the first air inlet 122 is disposed below the second air outlet 111.

[0112] In this embodiment, the indoor air flowing out from the second air outlet 111 moves vertically downwards and enters the heat exchange section 120 directly through the first air inlet 122. This further increases the airflow into the heat exchange section 120 and improves the heat exchange efficiency.

[0113] In some embodiments of the present invention, the opening direction of the second air inlet 112 is forward. In this embodiment, the second air inlet 112 is disposed on the upper side of the heat exchange section 120, and the opening direction is forward, which facilitates the flow of indoor air above the heat exchange section 120 into the circulation section 110 through the second air inlet 112.

[0114] In other embodiments of the present invention, the opening direction of the second air inlet 112 may also be upward. In this embodiment, the opening direction is upward to prevent the heat exchange air flowing out of the first air outlet 121 from directly entering the second air inlet 112 during its upward movement.

[0115] Of course, in some embodiments of the present invention, the opening direction of the second air inlet 112 may also be facing forward and upward.

[0116] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
