Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an indoor unit of a vertical air conditioner. Background Technology

[0002] In related technologies, the indoor units of vertical air conditioners typically reduce the feeling of airflow blowing on people by detecting the user's location and setting up windless zones. Some technologies use vertical air guide vanes fixed at a preset angle to direct the airflow to unoccupied areas, preventing the airflow from blowing directly on the user. However, the airflow will never reach the user, resulting in a poor user experience. In other technologies, the rotation of the vertical air guide vanes in the indoor units of vertical air conditioners does not take into account the user's movement. If the vertical air guide vanes rotate while the user moves, the airflow may still blow more towards the user, resulting in a still poor user experience. Summary of the Invention

The controller is configured to: when the controller receives a first control signal, the controller acquires the user's position fed back by the sensor and compares the user's position with the at least three boundary positions. If the user's position is located between two adjacent boundary positions in the rotation direction of the longitudinal air guide plate, the controller controls the longitudinal air guide plate to rotate randomly in multiple air guide areas, so that the air volume in the air guide area corresponding to the user's position is not greater than the air volume in any of the other air guide areas, and is less than the air volume in at least one of the other air guide areas.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this invention.

[0032] In the description of this invention, "a plurality of" means two or more, and "several" means one or more.

[0033] In the description of this invention, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or it may include the first and second features not being in direct contact but being in contact through another feature between them.

[0034] In the description of this invention, the terms "above," "over," and "on top" for the first feature and the second feature include the first feature being directly above or diagonally above the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature.

[0035] The indoor unit 1 of a vertical air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] like Figures 1-10 As shown, the indoor unit 1 of the vertical air conditioner according to an embodiment of the present invention includes a housing 100, a heat exchanger, a fan, a longitudinal air guide plate 400, a sensor 200, and a controller 300.

[0037] The housing 100 has an air inlet and an air outlet. A heat exchanger is installed inside the housing 100, and a fan is also installed inside the housing 100 to guide gas from the air inlet into the housing 100, where it exchanges heat with the heat exchanger, and then exits from the air outlet. A longitudinal air guide plate 400 is rotatably mounted on the housing 100 and located at the air outlet. The rotation axis of the longitudinal air guide plate extends along the axial direction of the housing 100. By rotating the longitudinal air guide plate 400, the flow direction of the gas exiting from the air outlet is adjusted. The longitudinal air guide plate 400 has at least three boundary positions 410 within its rotation range. Two adjacent boundary positions 410 define an air guiding area. A sensor 200 is installed on the housing 100 to detect the user's position. The controller 300 is installed inside the housing 100 and is connected to the longitudinal air guide plate 400 and the sensor 200 respectively. The controller 300 is configured such that when the controller 300 receives the first control signal, the controller 300 obtains the user position fed back by the sensor 200 and compares the user position with at least three boundary positions 410. If the user position is located between two adjacent boundary positions 410 in the rotation direction of the longitudinal air guide plate 400, the controller 300 controls the longitudinal air guide plate 400 to rotate randomly in multiple air guide areas, so that the air volume in the air guide area corresponding to the user position is not greater than the air volume in any of the other air guide areas, and is less than the air volume in at least one of the other air guide areas.

[0038] The first control signal enables the vertical air conditioner 1 to enter the natural wind mode.

[0039] When the user's position is at the dividing position 410 in the rotation direction of the longitudinal air guide plate 400, the user's position can be assigned to the adjacent right-hand air guide area according to the left-to-right direction of the vertical air conditioner indoor unit 1, or it can be assigned to the adjacent left-hand air guide area according to the right-to-left direction of the vertical air conditioner indoor unit 1. Alternatively, it can be adjusted according to the actual situation. For example, part of the dividing position 410 can belong to the left-hand air guide area, and another part of the dividing position 410 can belong to the right-hand air guide area. Of course, it is understood that both the leftmost dividing position 410 and the rightmost dividing position 410 have an air guide area on only one side. The leftmost dividing position 410 can be assigned to the adjacent air guide area, and the rightmost dividing position 410 can be assigned to the adjacent air guide area.

[0040] For example, when the longitudinal air guide plate 400 of the indoor unit 1 of the vertical air conditioner turns between two adjacent dividing positions 410, the longitudinal air guide plate 400 directs the air conditioning air to that air guiding area. The extension direction of the air outlet of the indoor unit 1 of the vertical air conditioner is the circumferential extension direction of the vertical air conditioner, that is, the horizontal extension direction.

[0041] According to an embodiment of the present invention, the indoor unit 1 of the vertical air conditioner uses a sensor 200 installed on the housing 100 to detect the user's position. For example, the sensor 200 can be an infrared sensor, which can detect the user's position and transmit the user's position signal to the controller 300. The controller 300 compares the user's position with the boundary position 410 to determine the air guiding area corresponding to the user's position.

[0042] In addition, when the air conditioner receives the first control signal, the controller 300 obtains the user's position fed back by the sensor 200 and compares the user's position with at least three dividing positions 410. If the user's position is located between two adjacent dividing positions 410 in the rotation direction of the longitudinal air guide plate 400, the controller 300 controls the longitudinal air guide plate 400 to rotate randomly according to the user's position. In this way, on the one hand, by controlling the longitudinal air guide plate 400 to rotate randomly, the air conditioning air is made closer to the natural wind, and the air outlet is more comfortable. On the other hand, by controlling the longitudinal air guide plate 400 to blow less air conditioning air towards the air guide area where the current user is located in the state of random blowing, more air conditioning air is avoided to blow onto the user's body, thus ensuring a better air conditioning air blowing feeling and a better user experience.

[0043] Furthermore, the airflow within the air guide area corresponding to the user's location is no greater than the airflow within any of the other air guide areas and less than the airflow within at least one of the other air guide areas. In other words, the airflow within the air guide area corresponding to the user's location can be the minimum, and at least one air guide area has an airflow greater than the airflow within the air guide area corresponding to the user's location. In this way, the vertical air guide plate 400 can direct more airflow into the air guide area with the largest airflow, thereby ensuring sufficient airflow from the air conditioner to achieve the purpose of cooling or heating the room more quickly. At the same time, it avoids a large amount of airflow blowing directly into the user's area, preventing the air conditioner from blowing directly on the user and improving the user's comfort.

[0044] Furthermore, the airflow within the air guide area corresponding to the user's location is no greater than the airflow within any of the other air guide areas. In other words, the airflow within the air guide area corresponding to the user's location is less than the airflow within the other air guide areas, not that there is no airflow within the air guide area corresponding to the user's location. While ensuring that the airflow within the air guide area corresponding to the user's location is less, it is also necessary to ensure that there is air conditioning air blowing through this air guide area, so that the air outlet of the vertical air conditioner indoor unit 1 is closer to the blowing method of natural wind. Moreover, compared with the traditional anti-direct-blow mode, the airflow of the vertical air conditioner indoor unit 1 in this embodiment of the invention will not always avoid the user. In this way, while avoiding a large amount of air conditioning air blowing directly on the user, a small amount of air conditioning air can be used to blow towards the user. This avoids a large amount of air conditioning air blowing directly on the user's body, and a small amount of air conditioning air can be used to blow towards the user to quickly provide the user with cooling or heating effects, thereby improving the user's air blowing experience.

[0045] Furthermore, the controller 300 can continuously acquire user position information detected by the sensor 200 to adjust the rotation mode of the longitudinal air guide plate 400, so that the rotation of the longitudinal air guide plate 400 can take into account the user's movement information, and prevent the longitudinal air guide plate 400 from rotating in the previous mode after the user's position changes. This ensures that less air conditioning air is blown to the user, thereby improving the user's air conditioning experience.

[0046] Thus, the air outlet of the indoor unit 1 of the vertical air conditioner according to the embodiment of the present invention can mimic natural wind, so that less air conditioning air blows towards the user, which has the advantages of strong disorder and comfortable air blowing.

[0047] In some specific embodiments of the present invention, such as Figures 1-6 As shown, the controller 300 is configured such that when the controller 300 receives the first control signal, if the user's position is not located between any two dividing positions 410 in the rotation direction of the longitudinal air guide plate 400, the controller 300 controls the longitudinal air guide plate 400 to rotate randomly in multiple air guide areas, so that the air volume in multiple air guide areas is different.

[0048] Understandably, the air outlet can only extend a portion of the circumference of the indoor unit 1 of the vertical air conditioner, rather than completely surrounding it. In other words, the air guiding range of the indoor unit 1 can only correspond to a part of the indoor area in the circumferential or longitudinal direction, while other areas are considered blind spots where no air conditioning air will blow directly into them. If a user is in this blind spot, the air conditioning air will not blow directly onto the user. However, although the air conditioning air will not blow directly onto the user, it may still cause airflow and affect the user's comfort. In this case, by controlling the vertical air guide plate 400 to continue rotating randomly, the air conditioning air can still be close to natural wind, thus simulating natural wind and further avoiding discomfort caused by the air conditioning air, resulting in a better user experience.

[0049] Furthermore, if a first control signal is received during the normal operation of the indoor unit 1 of the vertical air conditioner to activate the natural wind mode, that is, when the indoor unit 1 of the vertical air conditioner is normally cooling, heating or blowing air, and the user switches the operating mode of the indoor unit 1 of the vertical air conditioner to the natural wind mode, the vertical air guide plate 400 is reset (for example, the vertical air guide plate 400 is rotated to a direction perpendicular to the air outlet). Then the indoor unit 1 of the vertical air conditioner detects the air guide area where the user is located and controls the vertical air guide plate 400 to rotate randomly.

[0050] If the first control signal is received immediately when the indoor unit 1 of the vertical air conditioner is turned on, the natural wind mode is turned on. If the indoor unit 1 of the vertical air conditioner is in cooling or ventilation mode, the vertical air guide plate 400 is reset (for example, the vertical air guide plate 400 is rotated to a direction perpendicular to the air outlet). Then the indoor unit 1 of the vertical air conditioner detects the air guide area where the user is located and controls the vertical air guide plate 400 to rotate randomly.

[0051] If the indoor unit 1 of the vertical air conditioner is turned on for heating, it immediately receives the first control signal, indicating that the user immediately switches the operating mode of the indoor unit 1 to natural wind mode. The indoor unit 1 then first performs anti-cold air operation to prevent cold air from blowing directly on the user's body before heating. After the anti-cold air operation ends, the vertical air guide plate 400 is reset (for example, the vertical air guide plate 400 is rotated to a direction perpendicular to the air outlet). Then, the indoor unit 1 detects the air guide area where the user is located and controls the vertical air guide plate 400 to rotate randomly.

[0052] Understandably, when the indoor unit 1 of the vertical air conditioner is first turned on in heating mode, it cannot immediately blow out hot air. The indoor unit 1 will blow out some cold air or air conditioning air that is close to the indoor temperature. At this time, the anti-cold air refers to rotating the vertical air guide plate 400 and the horizontal air guide plate to a position tilted relative to the air outlet to expel this part of the air conditioning air and prevent it from blowing onto the user's body. When the indoor unit 1 of the vertical air conditioner starts heating and can blow out hot air, the anti-cold air is turned off, and the vertical air guide plate 400 is controlled to return to its original position and rotate randomly according to the air guide area where the user is located, which further improves the user's air blowing experience and makes the air blowing more comfortable.

[0053] Of course, the above-mentioned method of controlling the rotation of the vertical air guide plate is not only applicable to the indoor unit 1 of the vertical air conditioner receiving the first control signal immediately when it is turned on to heat. If the indoor unit 1 of the vertical air conditioner switches from the air supply mode to the heating mode and receives the first control signal, it can also control the indoor unit 1 of the vertical air conditioner to first prevent cold air. After the cold air prevention ends, the vertical air guide plate 400 is controlled to reset and then rotate randomly according to the air guide area where the user is located, which better improves the user's air blowing experience.

[0054] In some specific embodiments of the present invention, such as Figures 2-5 As shown, the multiple air guiding zones include at least a first zone 700, a second zone 800, and a third zone 900 arranged sequentially in the horizontal direction;

[0055] The controller 300 is configured such that when the controller 300 receives the first control signal, it compares the current user position in the rotation direction of the longitudinal air guide plate 400 with the boundary positions 410 on both sides of the first region 700, the boundary positions 410 on both sides of the second region 800, and the boundary positions 410 on both sides of the third region 900.

[0056] If the user's position is located between the boundary positions 410 on both sides of the first region 700 in the rotation direction of the longitudinal air guide plate 400, that is, the user's position is within the first region 700, then the longitudinal air guide plate 400 is controlled to rotate cyclically in the third region 900 for a first preset number of times, and then rotate cyclically in the first region 700 and the second region 800 as a whole for a second preset number of times, and repeat the first preset cycle.

[0057] If the user's position is located between the boundary positions 410 on both sides of the second region 800 in the rotation direction of the longitudinal air guide plate 400, that is, the user's position is within the second region 800, then the longitudinal air guide plate 400 is controlled to rotate cyclically a third preset number of times within one of the first region 700 and the third region 900, and then rotate cyclically a fourth preset number of times within the other of the first region 700 and the third region 900 and the second region 800 as a whole, and the second preset cycle is repeated.

[0058] If the user's position is located between the boundary positions 410 on both sides of the third region 900 in the rotation direction of the longitudinal air guide plate 400, that is, the user's position is within the third region 900, then the longitudinal air guide plate 400 is controlled to rotate cyclically for the fifth preset number of times in the first region 700, and then rotate cyclically for the sixth preset number of times in the entire second region 800 and the third region 900, and repeat the third preset cycle.

[0059] Specifically, after the vertical air guide plate 400 repeats the first preset cycle, the second cycle, or the third cycle, the indoor unit 1 of the vertical air conditioner detects the user's location again and adjusts the rotation mode of the vertical air guide plate 400 according to the air guide area where the user is located, so that the air supply of the indoor unit 1 of the vertical air conditioner can take into account the user's movement. This allows for timely adjustment of the rotation mode of the vertical air guide plate 400, further improving the user's air blowing experience.

[0060] For example, the first preset number of times, the second preset number of times, the third preset number of times, the fourth preset number of times, the fifth preset number of times, and the sixth preset number of times can be the same or different. For example, the first preset number of times, the second preset number of times, the third preset number of times, the fourth preset number of times, the fifth preset number of times, and the sixth preset number of times can all be 3 times.

[0061] The first preset cycle refers to repeating the vertical air guide plate 400 in the third region 900 for a first preset number of times, and then in the first region 700 and the second region 800 for a second preset number of times; the second preset cycle refers to repeating the vertical air guide plate 400 in one of the first region 700 and the third region 900 for a third preset number of times, and then in the other of the first region 700 and the third region 900 and the second region 800 as a whole for a fourth preset number of times; the third preset cycle refers to repeating the vertical air guide plate 400 in the first region 700 for a fifth preset number of times, and then in the second region 800 and the third region 900 as a whole for a sixth preset number of times.

[0062] Furthermore, the overall circulation rotation within the first region 700 and the second region 800 means that the longitudinal air guide plate 400 passes through the first region 700 and the second region 800 and rotates back and forth within the first region 700 and the second region 800; the overall circulation rotation within the second region 800 and the third region 900 means that the longitudinal air guide plate 400 passes through the second region 800 and the third region 900 and rotates back and forth within the second region 800 and the third region 900.

[0063] With this configuration, the vertical air guide plate 400 first circulates within the air guide area outside the user's location, and then circulates within the air guide area where the user is located and another adjacent air guide area. As a result, the air volume in the air guide area outside the user's location is larger per unit time. Furthermore, because the vertical air guide plate 400 circulates within the air guide area where the user is located and another adjacent air guide area, air conditioning air will be blown into the air guide area where the user is located intermittently, rather than continuously. This reduces the air volume in that air guide area, thereby reducing the direct air conditioning air blowing on the user's body. Moreover, the more disordered the rotation of the air conditioning air in multiple air guide areas, the more it simulates real natural wind, which is beneficial to improving the user's air conditioning experience.

[0064] Furthermore, by setting a preset number of times, the number of times the longitudinal air guide plate 400 continuously rotates in a single air guide area can be controlled, so that the longitudinal air guide plate 400 can rotate fully in a single air guide area. This allows the air conditioning air of the indoor unit 1 of the vertical air conditioner to be directed to the designated air guide area, and the air conditioning air can be controlled to change direction in a single air guide area. This results in greater disorder and a blowing method that is closer to natural wind.

[0065] In addition, by setting a preset cycle, the number of rotation cycles of the longitudinal air guide plate 400 can be controlled. When the number of rotation cycles of the longitudinal air guide plate 400 reaches the set number of cycles, the indoor unit 1 of the vertical air conditioner can detect the user's position again. When the user moves and causes a change in the current user's position, for example, the user moves from the first zone 700 to the second zone 800 or the third zone 900, or the user moves from the second zone 800 to the first zone 700 or the third zone 900, or the user moves from the third zone 900 to the first zone 700 or the second zone 800, or the user moves from the air guide area to outside of multiple air guide areas, or the user moves from outside of multiple air guide areas to within the air guide area, the indoor unit 1 of the vertical air conditioner can detect the change in the user's position in real time, thereby switching the rotation mode of the longitudinal air guide plate 400 to adapt to the user's position movement, further improving the user's air blowing experience, avoiding the air conditioner air blowing directly on the user due to the user's movement, and making the air blowing more comfortable.

[0066] In some specific embodiments of the present invention, such as Figure 2 and Figure 6As shown, the controller 300 is configured such that when the controller 300 receives the first control signal, if the user's position is not located between any two adjacent boundary positions 410 in the rotation direction of the longitudinal air guide plate 400, that is, the user's position is not located in multiple air guide areas, then the controller 300 controls the longitudinal air guide plate 400 to rotate cyclically for a seventh preset number of times in one of the first area 700 and the third area 900, and controls the longitudinal air guide plate 400 to rotate cyclically for an eighth preset number of times in the other of the first area 700 and the third area 900 and the second area 800 as a whole, and repeats the fourth preset cycle.

[0067] Specifically, after the longitudinal air guide plate 400 repeats the fourth cycle, the indoor unit 1 of the vertical air conditioner detects the user's position again through the sensor 200, and compares the user's position in the rotation direction of the longitudinal air guide plate 400 with the boundary positions 410 on both sides of the first area 700, the second area 800, and the third area 900. In order to adjust the rotation mode of the longitudinal air guide plate 400 in real time according to the air guide area where the user is located, the air supply of the indoor unit 1 of the vertical air conditioner can take into account the factors of user movement, so that the rotation mode of the longitudinal air guide plate 400 can be adjusted in time, further improving the user's air blowing experience.

[0068] For example, the seventh preset number of times and the eighth preset number of times can be the same or different. For example, both the seventh preset number of times and the eighth preset number of times can be 3 times.

[0069] Specifically, repeating the fourth preset cycle refers to repeating the longitudinal air guide plate 400's rotation within one of the first region 700 and the third region 900 a seventh preset number of times, and then repeating it within the other of the first region 700 and the third region 900 and the entire second region 800 an eighth preset number of times. Furthermore, the rotation within the other of the first region 700 and the third region 900 and the entire second region 800 means that the longitudinal air guide plate 400 passes through the other of the first region 700 and the third region 900 and the second region 800, rotating back and forth within each of these areas.

[0070] In other words, when the user is in the second zone 800 or outside the multiple air-guiding zones, the longitudinal air guide plate 400 can first circulate within the first zone 700 or circulate within the third zone 900.

[0071] In this way, even if the user is not in the airflow area, the vertical air guide plate 400 can control the air conditioning air to simulate the blowing mode of natural wind, so as to reduce the impact of air conditioning air on indoor airflow, thereby further avoiding discomfort caused by air conditioning airflow and providing a better user experience.

[0072] In some specific embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the included angles of the boundary positions 410 on both sides of the first region 700, the second region 800, and the third region 900 are equal. This ensures that the first region 700, the second region 800, and the third region 900 are the same size. By controlling the rotation speed of the longitudinal air guide plate 400 to be the same, the time taken for the longitudinal air guide plate 400 to pass through each air guide region in a single rotation can be controlled to be the same, thus ensuring that the airflow volume is the same when the longitudinal air guide plate 400 passes through each air guide region in a single rotation, facilitating control.

[0073] In some specific embodiments of the present invention, the first preset number of times is not less than the second preset number of times, the third preset number of times is not less than the fourth preset number of times, the fifth preset number of times is not less than the sixth preset number of times, and the seventh preset number of times is not less than the eighth preset number of times.

[0074] In other words, the first preset number of times can be greater than the second preset number of times, the third preset number of times can be greater than the fourth preset number of times, the fifth preset number of times can be greater than the sixth preset number of times, and the seventh preset number of times can be greater than the eighth preset number of times. In this way, the vertical air guide plate 400 can rotate more times in the air guide area outside the air guide area where the user is located, so that the air conditioning air can blow more towards the air guide area outside the air guide area where the user is located, further reducing the air conditioning air blowing directly on the user, and making the air blowing more comfortable.

[0075] Of course, the first and second preset counts can be the same, the third and fourth preset counts can be the same, the fifth and sixth preset counts can be the same, and the seventh and eighth preset counts can be the same; or, the first, second, third, fourth, fifth, sixth, seventh, and eighth preset counts can all be the same.

[0076] In some specific embodiments of the present invention, the first preset period, the second preset period, the third preset period, and the fourth preset period are equal to and greater than 1.

[0077] For example, the first, second, third, and fourth preset cycles are equal and can all be 2, 3, 4, or 5. In this way, regardless of whether the current user is in any airflow zone or outside of an airflow zone, the number of rotation cycles of the longitudinal airflow guide 400 can be the same, so that the rotation time of the longitudinal airflow guide 400 is the same under different rotation modes, and the amount of airflow into the room after a single detection of the user's position is the same.

[0078] Furthermore, after detecting the current user's location, the longitudinal air guide plate 400 is controlled to rotate for at least two cycles to avoid frequently detecting the current user's location, thereby avoiding frequent switching of the rotation state of the longitudinal air guide plate 400, which helps to simplify the rotation of the longitudinal air guide plate 400.

[0079] In some specific embodiments of the present invention, the longitudinal air guide plate 400 is provided with a first limit position 420 and a first limit position 430 in its rotation direction. The first limit position 420 and the first limit position 430 are both boundary positions 410. The area corresponding to the included angle between the first limit position 420 and the first limit position 430 is adapted to the air outlet in the rotation direction of the longitudinal air guide plate 400. In this way, the air guiding coverage of the longitudinal air guide plate 400 can be adapted to the coverage of the air outlet, the length of the air outlet will not be set too large, the structure is more reasonable, and the longitudinal air guide plate 400 can guide the air conditioning air along the horizontal extension direction of the air outlet to multiple positions in the room. In addition, it can avoid positional interference between the longitudinal air guide plate 400 and the side wall of the air outlet when rotating, and the air outlet will not block the air conditioning air guided by the longitudinal air guide plate 400, so that the air outlet of the indoor unit 1 of the vertical air conditioner is more unobstructed.

[0080] In some other specific embodiments of the present invention, the controller 300 is configured such that when the controller 300 receives the first control signal, if the user's position is located between two adjacent boundary positions 410 in the rotation direction of the longitudinal air guide plate 400, the controller 300 controls the longitudinal air guide plate 400 to rotate randomly in multiple air guide areas, and the number of times the longitudinal air guide plate 400 rotates in the air guide area corresponding to the user's position is less than the number of times the longitudinal air guide plate 400 rotates in any one of the other air guide areas.

[0081] In other words, the longitudinal air guide plate 400 rotates the fewest times within the air guide area corresponding to the user's position. As a result, the amount of air guided by the longitudinal air guide plate 400 into the air guide area corresponding to the current user's position is minimized in a single cycle, further reducing the amount of air conditioning air blowing directly onto the user's body and providing a better user experience.

[0082] In some specific embodiments of the present invention, such as Figure 10 As shown, the indoor unit 1 of the vertical air conditioner also includes at least one of a remote control device 500 and a control switch 600. The remote control device 500 is configured to send a first control signal to the controller 300 to turn the natural wind mode on or off. The control switch 600 is mounted on the housing 100 and is configured to send a first control signal to turn the natural wind mode on or off.

[0083] Thus, in some embodiments, the user can control and adjust the operating mode of the indoor unit 1 of the vertical air conditioner via buttons on the remote control device 500. In other embodiments, the user can also control and adjust the operating mode of the indoor unit 1 of the vertical air conditioner by directly touching the control switch 600 on the housing 100 of the indoor unit 1, making it more convenient for the user.

[0084] The other configurations and operations of the vertical air conditioner indoor unit 1 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0085] In this application, the indoor unit 1 of a vertical air conditioner performs a refrigeration cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0086] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0087] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the indoor unit 1 of the vertical air conditioner regulates the temperature and humidity of the indoor space.
