Detailed Implementation

[0021] In the description of the embodiments of this application, it should be noted that the terms "height direction", "up", "down", "top", "bottom", "left", "right", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0022] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "support" should be interpreted broadly. For example, they can refer to fixed supports, detachable supports, or integral supports; they can refer to mechanical supports or electrical supports; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Please see Figures 1 to 12 This application provides an indoor unit 10. The indoor unit 10 includes an indoor air duct assembly 11, a temperature sensing bulb 13, and a mounting structure 14.

[0024] It is understandable that the indoor unit 10 can be a separate air conditioning indoor unit or integrated into a single air conditioning unit; there are no restrictions on this.

[0025] This application provides an air conditioner 100, including an outdoor unit 20 and an indoor unit 10 in any embodiment of this application. The indoor unit 10 includes an indoor heat exchanger 12, which is located on the front side of the volute 111. The outdoor unit 20 includes an outdoor heat exchanger 21, which is in heat exchange communication with the indoor heat exchanger 12.

[0026] It is understood that the type of air conditioner 100 in this application is not limited. For example, it can be a window air conditioner. The window air conditioner is an integrated air conditioner, that is, the outdoor unit 20 and the indoor unit 10 are integrated into one box, so that the structure is compact and the space occupied is reduced.

[0027] For example, a mounting opening is formed in the wall, a window can be disposed in the mounting opening, and the air conditioner 100 can be installed in the mounting opening. The two sides of the window are the indoor side and the outdoor side, respectively. The indoor unit 10 is located on the indoor side of the window, and the outdoor unit 20 is located on the outdoor side of the window. Of course, the air conditioner 100 can also be installed in other locations that are substantially similar to the window. For example, the air conditioner 100 can be installed on the wall through a housing 40. The housing 40 may include an indoor housing and an outdoor housing. The outdoor housing is disposed outside the outdoor unit 20 and is mounted to the wall, while the indoor housing is disposed outside the indoor unit 10 and exposed to the indoor environment.

[0028] For example, the air conditioner 100 can be a PTAC (Packaged Terminal Air Conditioner) window unit, that is, the air conditioner 100 has a fresh air function while cooling and heating, thus improving air quality.

[0029] In some embodiments, please refer to Figure 1 and Figure 2 The air conditioner 100 includes a chassis 30, an outer casing 40, and a partition 50. The outer casing 40 covers the chassis 30. The outdoor unit 20 and the indoor unit 10 are disposed within the space defined by the chassis 30 and the outer casing 40. The partition 50 separates the indoor unit 10 and the outdoor unit 20.

[0030] The chassis 30 is positioned at the bottom of the outdoor unit 20 and the indoor unit 10 to support them. The outer casing 40 covers the chassis 30. Thus, the outdoor unit 20 and the indoor unit 10 are located within the space defined by the chassis 30 and the outer casing 40, providing protection for them and ensuring the overall structural stability of the air conditioner 100, facilitating its installation. The partition 50 separates the indoor unit 10 and the outdoor unit 20; that is, the indoor unit 10 is located on the side of the partition 50 facing inwards, and the outdoor unit 20 is located on the side of the partition 50 facing outwards.

[0031] Understandably, without a partition, the cold air drawn in by the indoor fan may leak directly from the casing to the outdoor side, or the hot air drawn in by the outdoor fan may directly enter the indoor side, causing a decrease in the cooling and heating efficiency of the air conditioner and affecting its performance.

[0032] Therefore, the partition 50 is used to isolate indoor air from outdoor air. The partition 50 can physically block the direct connection between the indoor air duct 10a and the outdoor air duct, so that on the indoor side, indoor air can only be drawn in by the indoor fan 17, exchange heat through the indoor heat exchanger 12, and then blown back into the room; outdoor air can only be drawn in by the outdoor fan, exchange heat through the outdoor heat exchanger 21, and then discharged to the outside. This allows the air conditioner 100 to efficiently complete the heat exchange process of indoor heat absorption and outdoor heat release (cooling) or outdoor heat absorption and indoor heat release (heating). Of course, the partition 50 also provides a certain structural support and dust and water protection, reducing the chance of rainwater and dust directly entering the indoor side.

[0033] The partition 50 can be made of sheet metal, which is lightweight and easy to mass-produce, thus ensuring the structural strength of the partition 50.

[0034] The indoor heat exchanger 12 and the outdoor heat exchanger 21 are used as evaporators or condensers. The working principle of the air conditioner 100 is briefly described below.

[0035] In cooling mode, the outdoor heat exchanger 21 acts as a condenser, and the indoor heat exchanger 12 acts as an evaporator. The compressor draws in low-temperature, low-pressure gaseous refrigerant and compresses it into high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant enters the outdoor heat exchanger 21, and the outdoor fan draws in outdoor air. The high-temperature, high-pressure refrigerant exchanges heat with the outdoor air, causing its temperature to drop, thus condensing from a gaseous state into a liquid state. At the same time, it releases a large amount of heat to the outdoor air. The high-temperature liquid refrigerant passes through a throttling device and becomes a low-temperature, low-pressure liquid refrigerant, which then enters the indoor heat exchanger 12. The indoor fan 17 draws in indoor air, and the low-temperature, low-pressure liquid refrigerant exchanges heat with the indoor air, absorbing heat from the indoor air and evaporating from a liquid state into a gaseous state. At the same time, it lowers the indoor air temperature, and the cooled air is blown back into the room, achieving cooling.

[0036] In heating mode, the outdoor heat exchanger 21 is used as an evaporator, and the indoor heat exchanger 12 is used as a condenser. The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas. The high-temperature, high-pressure gas first enters the room and exchanges heat with the indoor heat exchanger 12. The indoor fan 17 blows through the indoor heat exchanger 12, and the refrigerant releases heat to the indoor air and condenses into a liquid, thus raising the temperature of the indoor air. The high-temperature liquid refrigerant passes through a throttling device and becomes a low-temperature liquid. The low-temperature liquid refrigerant enters the outdoor heat exchanger 21, where it absorbs heat from the outdoor air and evaporates into a gas. In this way, heating is achieved.

[0037] The indoor air duct assembly 11 has an indoor air duct 10a for introducing heat exchange airflow into the room, and the indoor air duct assembly 11 includes a volute 111.

[0038] The indoor air duct assembly 11 is the structure used to form the indoor air duct 10a, and the volute 111 is part of the indoor air duct assembly 11, and the volute 111 participates in forming at least a part of the indoor air duct 10a.

[0039] For example, please refer to Figure 2 and Figure 3 The volute 111 is located behind the indoor heat exchanger 12, and the volute 111 and the indoor heat exchanger 12 are arranged at intervals in the front-to-back direction. The indoor fan 17 is located in the indoor air duct 10a, between the indoor heat exchanger 12 and the volute 111. The airflow exchanges heat with the indoor heat exchanger 12 before entering the indoor air duct 10a. The volute 111 can guide the airflow, so that the airflow can leave the indoor air duct 10a correctly and smoothly according to a predetermined path and flow into the indoor environment.

[0040] Please see Figures 3 to 8 The temperature sensor 13 is located on the side of the volute 111 away from the indoor air duct 10a. The temperature sensor 13 includes a temperature sensing part 131, which is connected to the indoor air duct 10a.

[0041] In other words, the temperature sensor 13 is located outside the indoor air duct assembly 11, and is not located inside the indoor air duct 10a. For example, the temperature sensor 13 is located on the rear side of the volute 111, that is, on the side of the volute 111 away from the indoor heat exchanger 12, to reduce interference between the temperature sensor 13 and the indoor heat exchanger 12.

[0042] The temperature sensing part 131 refers to the part on the temperature sensing bulb 13 used to sense temperature. The temperature sensing bulb 13 senses the temperature through the temperature sensing part 131. The temperature sensing part 131 is connected to the indoor air duct 10a, that is, the temperature sensing part 131 can directly contact the airflow in the air duct, thereby sensing the temperature of the airflow in the indoor air duct 10a, detecting and providing feedback on the temperature of the heat exchange airflow. The temperature sensing bulb 13 can be electrically connected to the electronic control module 16 to transmit the temperature detection signal to the electronic control module 16, thereby facilitating the determination of the current operating status of the air conditioner 100, so that the electronic control module 16 can adjust the air conditioner 100 in a timely manner.

[0043] For example, in heating mode, the temperature sensor 13 can detect and provide real-time feedback on the airflow temperature of the indoor air duct 10a to control the operating speed of the indoor fan 17. When the airflow temperature in the indoor air duct 10a reaches the set temperature, the operating speed of the indoor fan 17 is increased to reduce the likelihood of blowing cold air into the indoor environment. In cooling mode, the temperature sensor 13 can also detect the temperature of the indoor air duct 10a. If the airflow is too cold, the speed of the indoor fan 17 can be reduced; if the airflow temperature is insufficient, the speed of the indoor fan 17 can be increased.

[0044] For example, the temperature sensing bulb 13 is positioned near the air outlet 10b of the indoor air duct 10a.

[0045] The specific structure of the temperature sensing bulb 13 is not limited. For example, it can be a temperature-pressure converter that converts the temperature signal into a pressure signal.

[0046] The temperature sensing part 131 can be cylindrical and filled with a temperature sensing working fluid.

[0047] At least a portion of the mounting structure 14 and the volute 111 are integrally formed. That is, the mounting structure 14 is integrally formed on the volute 111. The mounting structure 14 can be integrally formed with a part of the structure of the volute 111. In this case, the volute 111 can be assembled from multiple parts, with the mounting structure 14 integrally formed with one of the parts. Alternatively, the mounting structure 14 can be integrally formed with all the structures of the volute 111. In this case, the volute 111 is an integral structure, and the mounting structure 14 is formed simultaneously on the volute 111 during its forming.

[0048] For example, at least a portion of the mounting structure 14 and the volute 111 are integrally formed by stamping.

[0049] The mounting structure 14 is formed on the side of the volute 111 away from the indoor air duct 10a to facilitate the installation of the temperature sensor 13.

[0050] The mounting structure 14 forms a limiting space 14a, through which at least a portion of the temperature sensing part 131 is inserted and constrained.

[0051] The mounting structure 14 is used to install the temperature sensing part 131 through the limiting space 14a. The mounting structure 14 defines the limiting space 14a by its own structure. At least a part of the temperature sensing part 131 passes through and is constrained by the limiting space 14a. This means that the limiting space 14a is adapted to the size and shape of the temperature sensing part 131. When the temperature sensing part 131 passes through the limiting space 14a for installation, it can be restricted by the limiting space 14a and cannot move, rotate or fall off at will. In this way, the risk of displacement of the temperature sensing part 131 is reduced, the positional consistency of the temperature sensing part 131 is ensured, and it is convenient to provide a continuous and accurate temperature signal. Of course, it also protects the temperature sensing bulb 13 and reduces the probability of damage to the temperature sensing bulb 13.

[0052] Understandably, in related technologies, the temperature sensor is fixed to the volute by adding extra parts and screws, which increases the number of parts, the number of installation steps, and the installation cost.

[0053] The indoor unit 10 provided in the application embodiment has its mounting structure 14 integrally formed on the volute 111, eliminating the need for separate manufacturing, reducing the number of parts and installation steps. During assembly, only the temperature sensing part 131 needs to be fitted with the mounting structure 14, which improves manufacturing and assembly efficiency and reduces costs. Furthermore, the limiting space 14a of the mounting structure 14 allows the temperature sensing part 131 to be installed simply by passing it through, which is simple and convenient. The limiting space 14a also constrains and protects the temperature sensing part 131, ensuring close contact between the temperature sensing part 131 and the airflow in the indoor air duct 10a, reducing the likelihood of displacement, loosening, or damage from external forces, and facilitating accurate detection by the temperature sensor 13.

[0054] The number of mounting structures 14 can be one or more; for example, please refer to [link to example]. Figure 6 There are two mounting structures 14, and the two mounting structures 14 are spaced apart along the first direction.

[0055] In some embodiments, the volute 111 is a one-piece structure. Exemplarily, the volute 111 is a one-piece stamped part.

[0056] In this embodiment, the volute 111 and the mounting structure 14 are manufactured as a single piece, which is simple and convenient to manufacture, and has high production and assembly efficiency, further reducing the assembly process of the indoor unit 10.

[0057] In some embodiments, please refer to Figure 4 The indoor unit 10 includes a sealing element 15, which is sealed to the volute 111 to form an insulation cavity. The temperature sensing element 131 and the mounting structure 14 are located inside the insulation cavity.

[0058] In this embodiment, the heat insulation cavity defined by the sealing element 15 and the volute 111 can isolate the temperature sensing element 131 from the external environment, so that the temperature sensing element 13 remains in contact with the airflow of the indoor air duct 10a and is not affected by the external environment, thereby improving the reliability of detection. At the same time, it reduces the probability of air leakage in the indoor air duct 10a and ensures the stability of the air outlet of the indoor air duct 10a.

[0059] The specific structure of the seal 15 is not limited; it can be sponge, felt, etc., and there are no restrictions here.

[0060] In some embodiments, please refer to Figure 7 and Figure 8 The volute 111 includes a first mounting surface 111a, which is disposed away from the indoor air duct 10a. The first mounting surface 111a is provided with a through mounting port. The mounting structure 14 is connected to the mounting port. The part of the mounting port that is not closed by the mounting structure 14 forms a connecting port 111b. The temperature sensing part 131 is exposed to the indoor air duct 10a through the connecting port 111b.

[0061] It is understandable that the mounting port is a virtual structure used to represent the mounting position of the mounting structure 14. The mounting structure 14 and the mounting port are integrally formed.

[0062] The temperature sensing part 131 is exposed in the indoor air duct 10a through the connecting port 111b, which means that part of the outer surface of the temperature sensing part 131 can be exposed in the indoor air duct 10a.

[0063] In this embodiment, the mounting structure 14 is connected to the mounting port and closes part of the mounting port to provide mounting support for the temperature sensing unit 131 and facilitate sufficient limiting. The mounting structure 14 does not completely cover the mounting port. The part of the mounting port that is not closed by the mounting structure 14 forms a connecting port 111b so that the temperature sensing unit 131 can directly contact the airflow of the indoor air duct 10a, thereby improving the detection reliability while ensuring stable installation.

[0064] In some embodiments, please refer to Figure 7 and Figure 8 The mounting structure 14 includes a first protrusion 141, which protrudes along the first mounting surface 111a in a direction away from the indoor air duct 10a to define at least a portion of the limiting space 14a. The temperature sensing part 131 is inserted into the first protrusion 141 along a first direction, wherein the first direction is perpendicular to the height direction of the indoor unit 10.

[0065] For example, the first direction can be perpendicular to the front-back direction, or the first direction can be the left-right direction.

[0066] The first convex 141 is a structure that protrudes outward from the outdoor air duct. For example, the first convex 141 is generally formed in an arch shape to accommodate the size and shape of the temperature sensing part 131.

[0067] In this embodiment, the first convex 141 facilitates the formation of a limiting space 14a, allowing the temperature sensing part 131 to pass through and constraining the temperature sensing part 131, reducing the probability of the temperature sensing part 131 shifting. At the same time, the first convex 141 can also support the temperature sensing part 131, improving the installation strength of the temperature sensing part 131 and increasing the stability of the temperature sensing part 131 under the action of airflow.

[0068] In some embodiments, please refer to Figure 7 and Figure 8 The mounting structure 14 includes a second protrusion 142, which is connected to the end of the mounting opening along the first direction and protrudes in a direction away from the indoor air duct 10a. The temperature sensing part 131 passes through the first protrusion 141 along the first direction and is limited and abutted against the second protrusion 142.

[0069] In other words, the temperature sensing part 131 first passes through the space inside the first convex 141 and then contacts the second convex 142. When the temperature sensing part 131 contacts the second convex 142, it indicates that the temperature sensing part 131 is installed in place.

[0070] In this embodiment, the second protrusion 142 abuts against the temperature sensing part 131 along the first direction. On the one hand, it can provide a prompt for the installation of the temperature sensing part 131. When the temperature sensing part 131 abuts against the second protrusion 142, it indicates that the temperature sensing part 131 is installed in place, thus improving the reliability of installation. On the other hand, the second protrusion 142 limits the temperature sensing part 131, making the position of the temperature sensing part 131 stable, ensuring the consistency of the position of the temperature sensing part 131, and reducing the probability of the temperature sensing part 131 shifting along the first direction.

[0071] For example, the temperature sensing part 131 extends along a first direction.

[0072] It is understandable that the first convex hull 141 and the second convex hull 142 can be connected, that is, the mounting structure 14 is continuous at the first convex hull 141 and the second convex hull 142. Alternatively, the first convex hull 141 and the second convex hull 142 can be disconnected, that is, the mounting structure 14 is disconnected at the first convex hull 141 and the second convex hull 142.

[0073] In some embodiments, please refer to Figure 7 and Figure 8 The first convex hull 141 and the second convex hull 142 are spaced apart along the first direction.

[0074] In this embodiment, the first convex 141 and the second convex 142 are disconnected and there is no connection between them. The gap between the first convex 141 and the second convex 142 facilitates intuitive perception of the insertion of the temperature sensing part 131 and accurate installation. On the other hand, it also facilitates the formation of a partial structure of the communication port 111b between the first convex 141 and the second convex 142, so as to increase the contact area between the temperature sensing part 131 and the indoor air duct 10a.

[0075] In some embodiments, please refer to Figure 7 and Figure 8 The mounting opening has notches formed on opposite sides of the first protrusion 141 along the first direction, the two notches are interconnected and constitute at least a part of the connecting opening 111b.

[0076] In this embodiment, the two notches are interconnected, that is, the first convex 141 will not disconnect the two notches and the first convex 141 will not close the installation port. In this way, the connecting port 111b has sufficient size along the first direction, which is convenient to increase the area of ​​the temperature sensor 13 exposed in the indoor air duct 10a and improve the detection efficiency of the temperature sensor 13.

[0077] In some embodiments, please refer to Figure 7 and Figure 8 The mounting structure 14 includes a first guide portion 143, which is connected to the side of the first protrusion 141 away from the second protrusion 142. Along the direction from the first protrusion 141 to the second protrusion 142, the first guide portion 143 extends toward the direction close to the indoor air duct 10a.

[0078] During the installation of the temperature sensing part 131, the temperature sensing part 131 first contacts the first guide part 143, then passes through the first protrusion 141, and then abuts against the second protrusion 142 to complete the installation.

[0079] In this embodiment, when the temperature sensing part 131 contacts the first guide part 143, the first guide part 143 can guide the temperature sensing part 131 to move towards the direction close to the indoor air duct 10a, that is, guide the temperature sensing part 131 to move into the space inside the first protrusion 141. By guiding the movement of the temperature sensing part 131 through the first guide part 143, the installation reliability of the temperature sensing part 131 is improved.

[0080] In some embodiments, please refer to Figure 7 and Figure 8 The mounting structure 14 includes a second guide portion 144, which is disposed between the first convex 141 and the second convex 142. The second guide portion 144 is recessed toward the indoor air duct 10a and extends away from the indoor air duct 10a along the direction from the first convex 141 to the second convex 142.

[0081] After passing through the first protrusion 141, the temperature sensing part 131 moves towards the second protrusion 142 via the second guide part 144. It is understood that in embodiments where notches are provided on opposite sides of the first protrusion 141, the second guide part 144 effectively guides the temperature sensing part 131 to the second protrusion 142, reducing the likelihood of the temperature sensing part 131 directly penetrating into the indoor air duct 10a.

[0082] In this embodiment, after the temperature sensing part 131 passes through the first protrusion 141, it contacts the second guide part 144. The second guide part 144 guides the temperature sensing part 131 to move away from the indoor air duct 10a, that is, guides the temperature sensing part 131 not to enter the indoor air duct 10a, but to move towards the second protrusion 142. By guiding the temperature sensing part 131 through the second guide part 144, the installation reliability of the temperature sensing part 131 between the first guide part 143 and the second guide part 144 is improved.

[0083] In some embodiments, please refer to Figure 7 and Figure 8The mounting structure 14 includes a first support portion 145, which is recessed along the first mounting surface 111a toward the direction of the indoor air duct 10a. The first support portion 145 is disposed on the side of the first protrusion 141 away from the second protrusion 142 and is spaced apart from the first protrusion 141. The temperature sensing portion 131 is supported on the first support portion 145.

[0084] In this embodiment, the first support portion 145 is provided so that, on the one hand, it will not obstruct the passage of the temperature sensing portion 131 along the first direction, and on the other hand, it can provide support for the temperature sensing portion 131, increase the installation stability of the temperature sensing portion 131, improve the installation strength of the temperature sensing portion 131, and reduce the probability of the temperature sensing portion 131 shifting due to airflow.

[0085] The portion of the temperature sensing part 131 that is away from the second protrusion 142 is supported by the first support part 145, and the aforementioned gap is formed between the first support part 145 and the first protrusion 141.

[0086] In some embodiments, please refer to Figure 7 and Figure 8 The mounting structure 14 includes a second support portion 146, which is recessed along the first mounting surface 111a toward the indoor air duct 10a. The second support portion 146 is disposed between the first protrusion 141 and the second protrusion 142, and is spaced apart from the first protrusion 141 and the second protrusion 142 respectively. The temperature sensing portion 131 is supported on the second support portion 146.

[0087] In this embodiment, the second support 146 not only prevents the temperature sensing part 131 from being obstructed from passing through in the first direction, but also provides support for the temperature sensing part 131, increasing its installation stability, enhancing its installation strength, and reducing the likelihood of it shifting due to airflow.

[0088] For example, please refer to Figure 7 and Figure 8 The second support portion 146 is connected to the side of the second guide portion 144 away from the first protrusion 141. The mounting port is also formed with a notch between the second support portion 146 and the second protrusion 142 so that the temperature sensing portion 131 can contact the indoor air duct 10a.

[0089] In some embodiments, please refer to Figures 2 to 3 , Figures 6 to 7 The temperature sensing element 13 includes a connecting part 132, and the indoor unit 10 includes an electronic control module 16. The electronic control module 16 is disposed on one side of the indoor air duct assembly 11 along the first direction. One end of the connecting part 132 is connected to the temperature sensing element 131, and the other end is connected to the electronic control module 16.

[0090] For example, the electronic control module 16 is disposed on one side of the indoor air duct assembly 11 and the indoor heat exchanger 12 along the first direction.

[0091] The electronic control module 16 is located on the indoor side, making full use of the indoor space. On the one hand, the indoor location of the electronic control module 16 can effectively protect the electronic control module 16, reducing the impact of rain, snow, dust and other factors on the outdoor side. Moreover, the indoor temperature is more stable and milder than the outdoor temperature, which also helps to reduce the impact of low or high temperatures on the electronic control module 16. Of course, it also facilitates the maintenance of the electronic control module 16, increasing maintenance convenience. On the other hand, the high negative pressure at the indoor heat exchanger 12 facilitates air intake and heat exchange in the indoor heat exchanger 12. Thus, it is convenient to use the negative pressure air intake to dissipate heat from the electronic control module 16.

[0092] The connection part 132 is used to transmit the signal detected by the temperature sensing part 131 to the electronic control module 16 so that the electronic control module 16 can know the current temperature of the indoor air duct 10a and adaptively adjust the operating status of the air conditioner 100.

[0093] One end of the temperature sensing part 131 is installed along the first direction to abut against the first protrusion 141, and the other end is supported on the first support part 145 and connected to the connecting part 132.

[0094] In some embodiments, please refer to Figure 7 The connecting part 132 includes a bent pipe section 1321 and a straight pipe section 1322. The bent pipe section 1321 connects the straight pipe section 1322 and the temperature sensing part 131. The straight pipe section 1322 extends along a first direction and toward the end of the temperature sensing part 131 away from the bent pipe section 1321 to connect with the electronic control module 16.

[0095] For example, the bend section 1321 may be U-shaped.

[0096] One end of the straight pipe section 1322 is connected to the bent pipe section 1321, and the other end extends towards the end that abuts against the temperature sensing part 131 and the first convex 141. That is, in the overall extension of the temperature sensing bulb 13, the straight pipe section 1322 and the temperature sensing part 131 have overlapping dimensions in the first direction, and the temperature sensing bulb 13 is designed with a reverse fold.

[0097] In this embodiment, the design of the straight pipe section 1322 and the bent pipe section 1321 makes the installation and fixation of the temperature sensing bulb 13 more secure and reduces the chance of it falling off. At the same time, the straight pipe section 1322 extends along the first direction, which facilitates connection with the electronic control module 16 without the need for additional reversal.

[0098] In some embodiments, please refer to Figure 2 and Figure 3The indoor air duct assembly 11 includes a volute tongue 112, a first air duct plate 113 and a second air duct plate 114. The first air duct plate 113 and the second air duct plate 114 are respectively connected to the volute housing 111 and the volute tongue 112 on opposite sides along the first direction to jointly define the indoor air duct 10a. The volute tongue 112 and the volute housing 111 are spaced apart to define the air outlet 10b of the indoor air duct 10a.

[0099] For example, the indoor fan 17 is rotatably connected to the first air duct plate 113 and the second air duct plate 114 at both ends along its axial direction, respectively. The volute tongue 112 and the volute casing 111 are connected to the first air duct plate 113 and the second air duct plate 114, respectively. The indoor heat exchanger 12 is disposed in front of the first air duct plate 113 and the second air duct plate 114, with at least a portion of the volute tongue 112 located above the indoor heat exchanger 12. The volute tongue 112 and the volute casing 111 together rectify and guide the airflow, reducing airflow resistance and backflow, and suppressing eddies and aerodynamic noise.

[0100] For example, along the airflow direction, the gap between the volute tongue 112 and the volute shell 111 gradually increases, forming a gradually expanding air outlet, which converts dynamic pressure into static pressure and increases the air delivery distance.

[0101] The volute tongue 112 can be detachably connected to the first air duct plate 113 and the second air duct plate 114, and the volute housing 111 can also be detachably connected to the first air duct plate 113 and the second air duct plate 114.

[0102] Please see Figure 3 , Figure 10 and Figure 12 The indoor air duct assembly 11 includes a first air guide 115, which is disposed on the volute 111. The first air guide 115 and at least a portion thereof are integrally formed. The first air guide 115 is located below the top end of the volute 111. The first air guide 115 protrudes toward the volute tongue 112 and abuts against the first air duct plate 113 and / or the second air duct plate 114.

[0103] At least a portion of the first flow guide 115 and the volute 111 are integral structures, that is, the first flow guide 115 is integrally formed on the volute 111.

[0104] The first air guide 115 is located below the top of the volute 111, that is, the first air guide 115 is located downstream of the air outlet 10b.

[0105] The first flow guide 115 protrudes towards the volute tongue 112, that is, the first flow guide 115 protrudes towards the front side.

[0106] The first airflow guide 115 abuts against the first air duct plate 113 and / or the second air duct plate 114. There may be one first airflow guide 115 connected to the first air duct plate 113 or the second air duct plate 114. Alternatively, there may be two first airflow guide 115, with one first airflow guide 115 abutting against the first air duct plate 113 and the other first airflow guide 115 abutting against the second air duct plate 114.

[0107] In this embodiment, the first airflow guide 115 can guide the airflow when the heat exchange airflow near the first air duct plate 113 and / or the second air duct plate 114 flows towards the air outlet 10b along the first direction, thereby reducing the probability of airflow leakage at the junction of the volute 111 and the first air duct plate 113 and / or the second air duct plate 114, which would otherwise generate vibration and abnormal noise, and improving the stability of the wind field.

[0108] The first airflow guide 115 is integrally formed on the volute 111, with a simple structure and no splicing gaps, which facilitates effective airflow guidance and improves the airflow stability at the first air duct plate 113 and the second air duct plate 114.

[0109] In some embodiments, please refer to Figure 3 and Figure 10 The indoor air duct assembly 11 includes a second air guide 116, which protrudes from the side of the first air duct plate 113 and / or the second air duct plate 114 facing the volute 111.

[0110] The second air guide package 116 is located below the first air guide package 115, and an air guide space is formed between the two. Part of the airflow in the indoor air duct 10a flows to the air outlet 10b through the air guide space. The second air guide package 116 is integrally formed with the first air duct plate 113 and / or the second air duct plate 114.

[0111] The number of second airflow guide packages 116 can be one, which is disposed on the first air duct plate 113 or the second air duct plate 114 and integrally formed with the first air duct plate 113 or the second air duct plate 114; the number of second airflow guide packages 116 can be two, one of which is disposed on the first air duct plate 113 and integrally formed with the first air duct plate 113, and the other is disposed on the second air duct plate 114 and integrally formed with the second air duct plate 114.

[0112] In this embodiment, the heat exchange airflow near the first air duct plate 113 and / or the second air duct plate 114 along both sides of the first direction moves downward toward the direction of the volute tongue 112 under the action of the first guide package 115. Then, guided by the second guide package 116, it moves in the guide space formed by the first guide package 115 and the second guide package 116, and flows out along the volute tongue 112. Thus, the setting of the second guide package 116 can further guide the airflow, improve the stability of the wind field, and reduce abnormal noise.
