[0010] A fan is disposed inside the housing and between the heat exchanger and the air inlet, causing airflow to enter the housing from the air inlet, exchange heat with the heat exchanger, and then flow out of the housing from the air outlet.

[0011] The fan is a cross-flow fan, and the indoor unit of the air conditioner also includes a volute and a volute tongue that cooperate with the cross-flow fan, with the volute tongue located on the lower side of the volute.

[0026] In the indoor unit of the air conditioner of this utility model, since the refrigerant supplied to the first heat exchange section and the second heat exchange section can be different, the temperatures of the first heat exchange section and the second heat exchange section can be different, which in turn makes the temperatures of the airflows flowing out from the upper air outlet area and the lower air outlet area different.

[0041] Figure 1 This is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figure 2 This utility model provides an indoor unit for an air conditioner. The indoor unit includes a housing 100, an air guide plate 200, and a heat exchanger 300.

[0042] An air inlet 110 is provided at the rear or lower part of the housing 100, and an air outlet 120 communicating with the air inlet 110 is provided at the front of the housing 100. The air outlet 120 faces forward or downward.

[0043] The air guide plate 200 is located at the air outlet 120 and is configured to divide the air outlet 120 into an upper air outlet area 121 and a lower air outlet area 122.

[0044] A heat exchanger 300 is disposed inside the air outlet 120. The heat exchanger 300 includes a first heat exchange section 310 and a second heat exchange section 320. The first heat exchange section 310 is located below the second heat exchange section 320, such that at least a portion of the airflow flowing through the first heat exchange section 310 exits the housing 100 via the lower air outlet section 122, and at least a portion of the airflow flowing through the second heat exchange section 320 exits the housing 100 via the upper air outlet section 121. The heat exchanger 300 is configured to controllably distribute the flow rate of refrigerant in the first heat exchange section 310 or the second heat exchange section 320.

[0045] In this embodiment, airflow enters the housing 100 through the air inlet 110 and flows through the first heat exchange section 310 and the second heat exchange section 320 of the heat exchanger 300. Since the refrigerant distributed in the first heat exchange section 310 and the second heat exchange section 320 can be different, the temperatures of the first heat exchange section 310 and the second heat exchange section 320 can be different, which in turn makes the temperatures of the airflows flowing out from the upper air outlet section 121 and the lower air outlet section 122 different. The airflows of different temperatures converge outside the air outlet 120 and flow into the room to regulate the room temperature.

[0046] The indoor unit of this air conditioner adjusts the refrigerant flow rate of the first heat exchange section 310 or the second heat exchange section 320 according to the user's needs. The airflows from the upper air outlet 121 and the lower air outlet 122 are mixed at the air outlet 120. The mixed airflow flows into the room, avoiding the discomfort caused by cold air blowing directly on the user. This solves the problem that cold air blowing directly on the user can easily cause the body to catch a cold or feel uncomfortable, and achieves the purpose of avoiding the impact of cold air blowing directly on the user's health and improving the user experience.

[0047] In some embodiments of this utility model, when the indoor unit of the air conditioner is cooling and discharging air, the refrigerant in the second heat exchange section 320 is more than that in the first heat exchange section 310, so that the temperature of the air outlet area 121 on the indoor unit of the air conditioner is lower. When it flows out from the air outlet 120, it mixes with the warm airflow below and enters the room, thus avoiding cold air blowing directly on the user.

[0048] In addition, since the first heat exchange section 310 requires less refrigerant, the design of distributing different refrigerants to the first heat exchange section 310 and the second heat exchange section 320 also helps to reduce the energy consumption of the indoor unit of the air conditioner.

[0049] In some embodiments of this utility model, when the air conditioner is cooling the air, the refrigerant distributed in the first heat exchange section 310 and the second heat exchange section 320 can be adjusted to be the same to improve the heat exchange efficiency.

[0050] In some embodiments of this utility model, such as Figure 1 As shown, the air guide plate 200 is rotatably mounted at the air outlet 120 to have a partitioned position that divides the air outlet 120 into an upper air outlet area 121 and a lower air outlet area 122.

[0051] In this embodiment, the air guide plate 200 can not only adjust the air outlet angle by rotating, but also divide the air outlet 120 into an upper air outlet area 121 and a lower air outlet area 122 when the air guide plate 200 is rotated to the partition position.

[0052] Moreover, since the air guide plate 200 is rotatable, the air guide plate 200 in the partition position can be rotated to adjust the ratio of the upper air outlet zone 121 and the lower air outlet zone 122 according to the indoor environment or user needs, so that the indoor unit of the air conditioner can meet the various needs of users or different scenarios.

[0053] In some alternative embodiments of this utility model, the air guide plate 200 is fixedly connected to the air outlet 120 to divide the air outlet 120 into an upper air outlet area 121 and a lower air outlet area 122.

[0054] In some alternative embodiments of this utility model, the air guide plate 200 has only one air distribution position and one closed position.

[0055] In this embodiment, when the indoor unit of the air conditioner is turned on, the air guide plate 200 is in the air distribution position. When the indoor unit of the air conditioner is turned off, the air guide plate 200 is in the closed position. Providing only two positions for the air guide plate 200 facilitates user operation and reduces the production cost of the indoor unit of the air conditioner.

[0056] In some embodiments of this utility model, such as Figure 1As shown, the indoor unit of the air conditioner also includes a fan 400, which is located inside the housing 100 and between the heat exchanger 300 and the air inlet 110. The fan 400 causes the airflow to enter the housing 100 from the air inlet 110, exchange heat with the heat exchanger 300, and then flow out of the housing 100 from the air outlet 120.

[0057] The fan 400 is a cross-flow fan. The indoor unit of the air conditioner also includes a volute 130 and a volute tongue 140 that cooperate with the cross-flow fan. The volute tongue 140 is located on the lower side of the volute 130.

[0058] In this embodiment, the cross-flow fan features a compact structure and uniform airflow distribution. Furthermore, compared to other fan types, the cross-flow fan operates with lower noise and energy consumption, and can generate a more stable laminar airflow. In addition, the airflow velocity is higher at the location far from the impeller center of the cross-flow fan. The structural design of the fan 400, volute 130, and volute tongue 140 allows the airflow to be concentrated at high speed at the outlet 120 while maintaining low eddy current losses.

[0059] When the fan 400 is running, the airflow enters from the air inlet 110 through the structural cooperation of the fan 400, the volute tongue 140 and the volute casing 130. After entering, the airflow is first guided by the volute casing 130 and the volute tongue 140, and then undergoes full heat exchange through the heat exchanger 300 before finally being sent out from the air outlet 120.

[0060] The structure of the lower volute tongue 140 also effectively suppresses the turbulence phenomenon at the outlet of the volute 130, improves the airflow delivery efficiency, and reduces operating noise. By improving the airflow quality, the air delivery is more gentle and comfortable, which can bring users a quieter and more energy-efficient user experience.

[0061] In some embodiments of this utility model, such as Figure 1 As shown, when the air guide plate 200 is in the partitioned position, the rear end of the air guide plate 200 is located on the upper front side of the upper end of the first heat exchange section 310.

[0062] In this embodiment, when the air guide plate 200 rotates to the partition position, the air guide plate 200 is located on the upper front side of the upper end of the first heat exchange section 310, that is, the first heat exchange section 310 is located on the lower side of the air guide plate 200, so that the air guide plate 200 can direct the airflow passing through the first heat exchange section 310 to flow out through the lower air outlet section 122. Furthermore, since the airflow temperatures passing through the first heat exchange section 310 and the second heat exchange section 320 are different, the airflow temperatures flowing out of the upper air outlet section 121 and the lower air outlet section 122 are different, thus satisfying the conditions for achieving cold air mixing.

[0063] In some alternative embodiments of this utility model, such as Figure 1As shown, when the air guide plate 200 is in the partitioned position, the rear end of the air guide plate 200 is located at the lower front side of the upper end of the first heat exchange section 310, and at the upper front side of the lower end of the first heat exchange section 310.

[0064] In some embodiments of this utility model, such as Figure 1 As shown, the upper end of the second heat exchange section 320 is located on the upper front side of the lower end of the second heat exchange section 320, and the lower end of the second heat exchange section 320 is connected to the upper end of the first heat exchange section 310.

[0065] When the air guide plate 200 is in the partition position, the rear end of the air guide plate 200 is located on the lower front side or lower side of the upper end of the second heat exchange section 320.

[0066] In this embodiment, the second heat exchange section 320 adopts a forward-tilted installation structure, and its lower end forms a continuous heat exchange surface with the first heat exchange section 310. This inclined arrangement causes the airflow to have a natural upward trend when passing through the second heat exchange section 320. On the one hand, it can play a certain guiding role for the airflow, and on the other hand, it increases the contact area between the airflow and the heat exchanger 300 to improve the heat exchange efficiency.

[0067] The air guide plate 200 rotates to different positions to control the airflow distribution ratio and flow direction of the upper air outlet zone 121 and the lower air outlet zone 122. When the air guide plate 200 is in the partitioned position, it is located on the lower front side or lower side of the upper end of the second heat exchange section 320. That is, at least a portion of the second heat exchange section 320 is located on the upper side of the air guide plate 200, allowing the air guide plate 200 to direct at least a portion of the airflow passing through the second heat exchange section 320 through the upper air outlet zone 121. Furthermore, since the airflow temperatures passing through the first heat exchange section 310 and the second heat exchange section 320 are different, the airflow temperatures exiting from the upper air outlet zone 121 and the lower air outlet zone 122 are different, thus satisfying the conditions for achieving cold air mixing.

[0068] In some embodiments of this utility model, such as Figure 1 As shown, heat exchanger 300 can be a plate heat exchanger 300.

[0069] In some alternative embodiments of this utility model, the heat exchanger 300 can be a V-type heat exchanger 300, the rear end of the first heat exchange section 310 is located above the front end of the first heat exchange section 310, and the rear end of the first heat exchange section 310 is connected to the rear end of the second heat exchange section 320.

[0070] In some embodiments of this utility model, when the air guide plate 200 is in the partition position, the distance between the rear end of the air guide plate 200 and the heat exchanger 300 is less than or equal to 400mm.

[0071] The width of the portion of the air guide plate 200 extending out of the air outlet 120 is greater than or equal to 150mm.

[0072] The width of the air guide plate 200 is greater than or equal to 300mm.

[0073] In this embodiment, the spacing between the rear end of the air guide plate 200 and the heat exchanger 300 is designed to be within 400mm, which not only avoids airflow diffusion loss caused by excessive space, but also saves space between the air guide plate 200 and the heat exchanger 300, thus providing conditions for reducing the volume of the shell 100.

[0074] The air guide plate 200, with a width of more than 150mm extending out of the air outlet 120 and an overall width of more than 300mm, provides sufficient contact area for the airflow guidance process, enabling the airflow to be separated and guided to the upper air outlet area 121 or the lower air outlet area 122.

[0075] In some embodiments of this utility model, the indoor unit of the air conditioner also includes a throttling device.

[0076] like Figure 2 As shown, the heat exchanger 300 also includes a control valve 330 configured to controllably connect one of the first heat exchange section 310 and the second heat exchange section 320 to the throttling device.

[0077] In this embodiment, the cooperation between the throttling device and the control valve 330 realizes the control of the refrigerant flow path and flow rate. The control valve 330 can selectively connect the throttling device to the first heat exchange section 310 or the second heat exchange section 320 according to the required mode, so as to achieve the purpose of dynamically adjustable refrigerant distribution, enabling the indoor unit of the air conditioner to flexibly select various operating modes such as lower heat exchange alone or upper heat exchange alone according to the indoor environment and user needs.

[0078] In some embodiments of the present invention, the control valve 330 is also configured to controllably connect the first heat exchange section 310 and the second heat exchange section 320 to the throttling device simultaneously.

[0079] In this embodiment, the control valve 330 can intelligently switch between three working states: connecting the first heat exchange section 310 alone, connecting the second heat exchange section 320 alone, or connecting the first heat exchange section 310 and the second heat exchange section 320 simultaneously, so that the indoor unit of the air conditioner can flexibly select various operating modes such as lower heat exchange alone, upper heat exchange alone, or simultaneous heat exchange according to the indoor environment and user needs.

[0080] In some embodiments of this utility model, the indoor unit of the air conditioner also includes a human sensing device, which is configured to detect the position of a human body so as to control the heat exchanger 300 according to the position of the human body, and thereby control the flow rate of the refrigerant flowing into the first heat exchange section 310 or the second heat exchange section 320.

[0081] In this embodiment, the human sensing device can detect the location of the indoor user in real time and adjust the control valve 330 according to the human position, thereby achieving the purpose of distributing the refrigerant flow into the first heat exchange section 310 and the second heat exchange section 320.

[0082] For example, when a user is detected to be at the bottom of the indoor unit of the air conditioner, the refrigerant flow rate of the first heat exchange section 310 or the second heat exchange section 320 can be adjusted to achieve a gentle airflow effect and prevent the user from being directly blasted with cold air. When the user is located at a distance from the indoor unit of the air conditioner, the refrigerant flow rate of the first heat exchange section 310 or the second heat exchange section 320 can be adjusted to improve heat exchange efficiency and achieve the purpose of rapid heat exchange in the room.

[0083] In some embodiments of this utility model, such as Figure 1 As shown, the air guide plate 200 is flat.

[0084] In this embodiment, the air guide plate 200 adopts a plate structure, which increases the air guiding area of ​​the air guide plate 200. Moreover, the flat plate structure is easy to manufacture and reduces the production cost of the air guide plate 200.

[0085] In some embodiments of this utility model, multiple blades are provided on the lower air guide surface of the air guide plate 200. When blades are provided on the lower air guide surface of the air guide plate 200, the airflow in the lower air outlet zone 122 can be further guided.

[0086] In some embodiments of this utility model, multiple blades are provided on the upper air guide surface of the air guide plate 200. The blades on the upper air guide surface can further guide the airflow in the upper air outlet area 121.

[0087] In some embodiments of this utility model, the upper edge of the air outlet 120 is located above or above the lower edge of the air outlet 120.

[0088] In this embodiment, the upper edge of the air outlet 120 structure is located above or in front of the lower edge. When the airflow flows out of the air outlet 120, the upper edge of the air outlet 120 structure further guides the airflow flowing out of the upper air outlet area 121, so as to promote the airflow flowing out of the upper air outlet area 121 to fully mix with the airflow flowing out of the lower air outlet area 122.

[0089] Therefore, those skilled in the art should recognize that although many 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 present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
