Technical Field

[0002] In related technologies, air conditioners are equipped with room temperature sensors to detect the indoor ambient temperature. The operating parameters of the air conditioner are adjusted based on the detected indoor ambient temperature, thereby achieving more precise temperature control. However, in these technologies, the placement of the room temperature sensor is often unreasonable, leading to a significant deviation between the temperature detected by the sensor and the actual indoor ambient temperature. This results in a large temperature control error, making it difficult to achieve a comfortable temperature setting. Therefore, improvements are needed. Utility Model Content

[0055] The embodiments of this utility model are described in detail below. 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 this utility model, and should not be construed as limiting this utility model.

[0056] The following is for reference. Figures 1-17 This invention describes an air conditioner according to an embodiment of the present invention.

[0057] refer to Figures 1-4 An air conditioner according to an embodiment of the present invention includes: a housing 10, a fan component 20, a heat exchanger component 30, and a room temperature sensor 40.

[0058] The air conditioner can be a split-type air conditioner, such as a split-type floor-standing air conditioner. When the air conditioner is a split-type air conditioner, it can include an indoor unit 100 and an outdoor unit, wherein the indoor unit 100 includes the aforementioned casing 10, fan assembly 20, heat exchanger assembly 30, and room temperature sensor 40.

[0059] The casing 10 has an air inlet structure 11 and an air outlet 12. A fan component 20 and a heat exchanger component 30 are located inside the casing 10. For example, the air inlet structure 11 can be located on the rear side of the casing 10, and the air outlet 12 can be located on the front side of the casing 10, such as at the upper end of the casing 10. The fan component 20 can be a centrifugal fan 21, with its air inlet facing rearward and its air outlet facing upward. The casing 10 serves to prevent dust and protect the internal components. Air enters the casing 10 through the air inlet structure 11, exchanges heat with the heat exchanger component 30, and is then discharged into the room through the air outlet 12, thereby regulating the indoor temperature.

[0060] For example, an air guide plate 17 for opening and closing the air outlet 12 can be provided at the air outlet 12. There can be multiple air guide plates 17 arranged at intervals. When the air conditioner is started, the air guide plates 17 are opened and the air outlet 12 can deliver air.

[0061] For example, the housing 10 may include a front housing component 101 and a rear housing component 102. The front housing component 101 is connected to the front side of the rear housing component 102. An air inlet structure 11 may be formed on the rear housing component 102. An air outlet 12 may be formed on the front housing component 101. A heat exchanger component 30 may be located inside the rear housing component 102. A portion of the fan component 20 is located inside the rear housing component 102, and a portion of the fan component 20 is located inside the front housing component 101.

[0062] The heat exchanger component 30 and the air inlet structure 11 are arranged in a front-to-back direction. The room temperature sensor 40 is installed on the housing 10 and is located at the air inlet structure 11. For example, the air inlet structure 11 is located at the rear of the housing 10, and the heat exchanger component 30 is located at the front of the air inlet structure 11 and between the air inlet structure 11 and the fan component 20.

[0063] The room temperature sensor 40 is used to detect the indoor ambient temperature and transmit the temperature data to the control module of the air conditioner. The control module can control the frequency of the air conditioner's compressor, the speed of the fan component 20, etc., based on the temperature detected by the room temperature sensor 40, so that the temperature can quickly reach the set temperature value and the temperature control can be precise.

[0064] By mounting the room temperature sensor 40 at the air inlet structure 11 of the housing 10, compared with mounting the room temperature sensor 40 on the heat exchanger bracket, the distance between the room temperature sensor 40 and the heat exchanger component 30 can be larger, which can reduce the temperature radiation effect of the heat exchanger component 30 on the room temperature sensor 40, and make the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature smaller.

[0065] Furthermore, the orthographic projection of the room temperature sensor 40 onto the reference plane is the first projection, and the orthographic projection of the heat exchanger component 30 onto the reference plane is the second projection. The first projection and the second projection are spaced apart, and the reference plane is perpendicular to the front-back direction.

[0066] For example, refer to Figure 3 and Figure 4 ( Figure 3 and Figure 4 The arrows in the diagram indicate the direction of airflow. Driven by the fan component 20, indoor air is drawn into the housing 10 from the air intake structure 11. The indoor air flowing through the air intake structure 11 comes into contact with the room temperature sensor 40, which can detect the airflow temperature at the air intake structure 11. The airflow entering the housing 10 flows through the heat exchanger component 30 and exchanges heat with it. Then, it is discharged into the room from the air outlet 12 of the air conditioner through the fan component 20.

[0067] The room temperature sensor 40 is positioned separately from the heat exchanger component 30 on the reference plane, which avoids the room temperature sensor 40 being directly opposite the heat exchanger component 30 in the air inlet direction. This further increases the distance between the room temperature sensor 40 and the heat exchanger component 30, thereby reducing the temperature radiation effect of the heat exchanger component 30 on the room temperature sensor 40. This results in a smaller deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature, leading to a smaller temperature regulation error in the air conditioner, more precise control of the indoor temperature, and easier achievement of a comfortable temperature setting.

[0068] According to the embodiment of the present invention, by installing the room temperature sensor 40 at the air inlet structure 11 of the casing 10, the distance between the room temperature sensor 40 and the heat exchanger component 30 can be increased, reducing the temperature radiation influence of the heat exchanger component 30 on the room temperature sensor 40, and making the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature smaller. Furthermore, by setting the orthographic projection of the room temperature sensor 40 on the reference plane and the orthographic projection of the heat exchanger component 30 on the reference plane separately, the room temperature sensor 40 can be avoided from being directly opposite the heat exchanger component 30 in the air inlet direction, further increasing the distance between the room temperature sensor 40 and the heat exchanger component 30, further reducing the temperature radiation influence of the heat exchanger component 30 on the room temperature sensor 40, and further reducing the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature. As a result, the temperature adjustment error of the air conditioner is smaller, the control of the indoor temperature is more accurate, and it is easier to achieve a comfortable temperature setting value.

[0069] refer to Figures 3-4 According to some embodiments of the present invention, the distance between the first projection and the second projection is in the range of 15mm to 25mm.

[0070] For example, the distance between the first projection and the second projection can be 15mm, 20mm, 25mm, etc. If the distance between the first projection and the second projection is too small, the reduction in the temperature radiation effect of the heat exchanger component 30 on the room temperature sensor 40 will be small; if the distance between the first projection and the second projection is too large, it will result in a large area in the air inlet structure 11 that is offset from the heat exchanger component 30, thus affecting the air inlet effect.

[0071] By setting the distance between the first projection and the second projection to be 15mm to 25mm, the influence of the heat exchanger component 30 on the temperature radiation of the room temperature sensor 40 can be reduced more effectively, while the influence on the air intake effect can be reduced, ensuring the air intake effect and making the air intake resistance smaller.

[0072] refer to Figures 5-7 According to some embodiments of the present invention, the air inlet structure 11 includes a main air inlet structure 111 and an auxiliary air inlet structure 112. The air inlet area of ​​the main air inlet structure 111 is larger than the air inlet area of ​​the auxiliary air inlet structure 112. The heat exchanger component 30 is arranged opposite to the main air inlet structure 111 in the front-to-back direction. The auxiliary air inlet structure 112 is located on one side of the main air inlet structure 111 in the up-down direction. The room temperature sensor 40 is located at the auxiliary air inlet structure 112.

[0073] For example, the auxiliary air intake structure 112 can be located above the main air intake structure 111, or it can be located below the main air intake structure 111.

[0074] When indoor air enters the casing 10 through the air intake structure 11, the air through the main air intake structure 111 flows directly to the heat exchanger component 30 in the front-to-back direction, while the air through the auxiliary air intake structure 112 flows into the casing 10 in the front-to-back direction and then flows upward toward the position corresponding to the heat exchanger component 30, before flowing forward through the heat exchanger component 30. For example, if the auxiliary air intake structure 112 is located below the main air intake structure 111, the air through the main air intake structure 111 flows directly to the heat exchanger component 30 in the forward direction, while the air through the auxiliary air intake structure 112 flows into the casing 10 in the forward direction and then flows upward to the position opposite to the heat exchanger component 30, before flowing forward through the heat exchanger component 30.

[0075] By positioning the auxiliary air intake structure 112 on one side of the main air intake structure 111 along the vertical direction, and placing the room temperature sensor 40 at the auxiliary air intake structure 112, the distance between the room temperature sensor 40 and the heat exchanger component 30 can be increased since the auxiliary air intake structure 112 and the heat exchanger component 30 are not arranged opposite each other. This reduces the temperature radiation effect of the heat exchanger component 30 on the room temperature sensor 40, thereby reducing the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature. Consequently, the temperature regulation error of the air conditioner is smaller, and the control of the indoor temperature is more accurate.

[0076] refer to Figures 3-4 According to some embodiments of the present invention, the fan component 20 includes a fan 21 and a duct volute 22. The fan 21 is installed in the duct volute 22, and the impeller 211 of the fan 21 is located inside the duct volute 22. In the front-back direction, the heat exchanger component 30 is located between the impeller 211 and the main air intake structure 111.

[0077] Driven by the impeller 211, indoor air is drawn into the casing 10 from the main air intake structure 111 and the auxiliary air intake structure 112, flows through the heat exchanger component 30 and enters the air duct 22 inside the fan component 20, and then is discharged into the room from the air outlet 12.

[0078] By placing the heat exchanger component 30 between the impeller 211 and the main air intake structure 111, the air flowing through the heat exchanger component 30 can quickly flow into the fan component 20. This reduces the backflow of air near the heat exchanger component 30 that is affected by the radiation from the heat exchanger component 30 and flows back to the air intake structure 11, thus affecting the room temperature sensor 40 installed at the auxiliary air intake structure 112. As a result, the influence of the heat exchanger component 30 on the room temperature sensor 40 can be better reduced, and the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature can be smaller.

[0079] refer to Figures 5-7According to some embodiments of this utility model, the housing 10 includes a shell 13 and an air inlet grille 14. The shell 13 is provided with a vent 131, and the air inlet grille 14 is installed on the vent 131. The air inlet grille 14 and the vent 131 together constitute the air inlet structure 11. By installing the air inlet grille 14 on the vent 131, debris can be prevented from entering the interior of the air conditioner housing 10 through the vent 131, thus protecting the heat exchanger component 30, the fan component 20, and the temperature sensor.

[0080] refer to Figures 3-7 According to some embodiments of this utility model, an air inlet cavity is defined between the air inlet grille 14 and the outer wall of the housing 13. The vent 131 connects the air inlet cavity and the inner cavity of the housing 10. In the front-rear direction, the heat exchanger component 30 is arranged opposite to the vent 131, and the room temperature sensor 40 is located on the outer periphery of the vent 131. When the air conditioner is working, indoor air can enter the housing 10 through the air inlet grille 14, the air inlet cavity, and the vent 131 in sequence. After the air entering the housing 10 exchanges heat with the heat exchanger component 30, it is discharged into the room through the air outlet 12 via the fan component 20.

[0081] By defining an air inlet cavity between the air inlet grille 14 and the outer wall of the housing 13, and by positioning the room temperature sensor 40 on the outer periphery of the vent 131, the air flowing through the air inlet grille 14 can come into contact with the room temperature sensor 40 to detect the indoor ambient temperature. Furthermore, the airflow coming into contact with the room temperature sensor can pass through the air inlet cavity and the vent 131 into the housing 10, achieving airflow flow. This also avoids the room temperature sensor 40 being positioned opposite the vent 131, reducing the temperature radiation effect of the heat exchanger component 30 directly on the room temperature sensor 40 through the vent 131. Additionally, it reduces the impact of airflow near the heat exchanger component 30 flowing back to the room temperature sensor 40 through the vent 131, thus minimizing the impact on the accuracy of the room temperature sensor 40's detection. Ultimately, this further reduces the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature.

[0082] refer to Figures 3-7 According to some embodiments of the present invention, the air inlet grille 14 includes a grille portion 15 and a mounting portion 16. The mounting portion 16 is connected to both sides of the grille portion 15 in the vertical direction and is connected to the housing 13. The grille portion 15 and the vent 131 are arranged opposite to each other in the front-back direction. The grille portion 15 forms a main air inlet 151, and the mounting portion 16 forms an auxiliary air inlet 161. The auxiliary air inlet 161 is connected to the vent 131 through the air inlet cavity. The heat exchanger component 30 is arranged opposite to the grille portion 15 in the front-back direction.

[0083] For example, the auxiliary air inlet 161 can be formed on the upper mounting portion 16 or on the lower mounting portion 16.

[0084] Taking the auxiliary air inlet 161 located on the mounting part 16 on the lower side as an example, when the air conditioner is working, the air entering through the main air inlet 151 of the grille part 15 flows forward through the vent 131 and flows to the heat exchanger component 30. The air entering through the auxiliary air inlet 161 on the mounting part 16 flows into the air inlet cavity and then flows upward to the vent 131, and flows to the heat exchanger component 30 through the vent 131. This allows the distance between the room temperature sensor 40 and the heat exchanger component 30 to be larger, and the airflow path between the room temperature sensor 40 and the heat exchanger component 30 is not a straight line but a broken line, a curve, or a broken line plus a curve. This can more effectively reduce the influence of the heat exchanger component 30 on the room temperature sensor 40, making the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature smaller.

[0085] By arranging the heat exchanger component 30 and the grille section 15 opposite each other in the front-to-back direction, the air entering from the main air inlet 151 can flow directly to the heat exchanger component 30 in the front-to-back direction. This results in a shorter flow path and lower flow resistance for the airflow passing through the grille section 15 and flowing to the heat exchanger component 30, ensuring both air intake and heat exchange effects. Furthermore, by positioning the auxiliary air inlet 161 at the mounting section 16 of the air intake grille 14, the impact of the heat exchanger component 30 on the temperature measurement accuracy of the room temperature sensor 40 can be better reduced.

[0086] refer to Figures 3-4 According to some embodiments of this utility model, the air inlet cavity includes a main air inlet cavity 152 and an auxiliary air inlet cavity 164. The main air inlet cavity 152 is defined between the grille portion 15 and the outer wall surface of the housing 13. The main air inlet cavity 152 is opposite to and communicates with the vent 131. The auxiliary air inlet cavity 164 is defined between the mounting portion 16 with the auxiliary air inlet 161 and the outer wall surface of the housing 13. The auxiliary air inlet cavity 164 is communicated with the main air inlet cavity 152. The room temperature sensor 40 is installed on the side wall of the auxiliary air inlet cavity 164. The air inlet structure 11 includes a main air inlet structure 111 and an auxiliary air inlet structure 112. The grille portion 15 and the main air inlet cavity 152 together constitute the main air inlet structure 111, and the auxiliary air inlet 161 and the auxiliary air inlet cavity 164 together constitute the auxiliary air inlet structure 112.

[0087] For example, driven by the impeller 211, the air flowing into the housing 10 from the main air inlet 151 flows sequentially through the main air inlet 151, the main air inlet cavity 152, and the vent 131 in a roughly front-to-back direction before entering the housing 10. The indoor air flowing into the housing 10 from the auxiliary air inlet 161 flows into the auxiliary air inlet cavity 164 through the auxiliary air inlet 161. The airflow in the auxiliary air inlet cavity 164 comes into contact with the room temperature sensor 40. The room temperature sensor 40, which is installed on the side wall of the auxiliary air inlet cavity 164, detects the temperature of the air flowing into the auxiliary air inlet cavity 164. The air in the auxiliary air inlet cavity 164 then flows into the main air inlet cavity 152. For example, when the auxiliary air inlet cavity 164 is located below the main air inlet cavity 152, the air in the auxiliary air inlet cavity 164 flows upward into the main air inlet cavity 152, and then flows into the housing 10 through the vent 131.

[0088] By defining an auxiliary air intake cavity 164 between the mounting portion 16 of the air intake grille 14 and the outer wall of the housing 13, and by mounting the room temperature sensor 40 on the side wall of the auxiliary air intake cavity 164, the room temperature sensor 40 can detect the indoor air temperature entering the auxiliary air intake cavity 164 from the auxiliary air intake port 161. Since the auxiliary air intake cavity 164 is staggered from the vent 131 and the heat exchanger component 30, the influence of the heat exchanger component 30 on the temperature measurement of the room temperature sensor 40 can be reduced. Furthermore, the auxiliary air intake cavity 164 is connected to the main air intake cavity 152, allowing the air in the auxiliary air intake cavity 164 to flow into the main air intake cavity 152, maintaining continuous air circulation in the auxiliary air intake cavity 164, and making the air temperature contacted by the room temperature sensor 40 closer to the real-time indoor air temperature. This reduces the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor ambient temperature, resulting in a smaller temperature regulation error of the air conditioner.

[0089] According to some embodiments of this utility model, the orthographic projection of the vent 131 on the reference plane is a third projection, which is located within the second projection, and the reference plane is perpendicular to the front-back direction. By making the projection of the vent 131 on the reference plane located within the projection of the heat exchanger component 30 on the reference plane, the airflow passing through the vent 131 can flow directly to the heat exchanger component 30 in the front-back direction, avoiding a longer flow path for the air entering from the portion offset between the vent 131 and the heat exchanger component 30, thereby ensuring the air intake effect and heat exchange effect. Furthermore, it allows for a larger distance between the room temperature sensor 40 and the vent 131, further reducing the influence of the heat exchanger component 30 on the temperature radiation of the room temperature sensor 40 through the vent 131 and reducing the impact of airflow within the housing 10 returning to the room temperature sensor 40 through the vent 131 on the temperature measurement results.

[0090] According to some embodiments of this utility model, the orthographic projection of the main air inlet cavity 152 onto the reference plane is the fourth projection, and the second projection is located within the fourth projection. The reference plane is perpendicular to the front-back direction. By making the projection of the heat exchange component onto the reference plane located within the projection of the main air inlet cavity 152 onto the reference plane, the influence of heat radiation from the heat exchanger component 30 on the air on both sides of the main air inlet cavity 152 can be reduced. This reduces the influence of heat radiation from the heat exchanger component 30 on the auxiliary air inlet cavity 164, resulting in a smaller deviation between the detected temperature of the room temperature sensor 40 located on the side wall of the auxiliary air inlet cavity 164 and the indoor temperature, thus reducing the temperature regulation error of the air conditioner.

[0091] Taking the auxiliary air inlet cavity 164 located below the main air inlet cavity 152 as an example, the lower edge of the second projection can be located above the lower edge of the fourth projection. This can reduce the influence of heat radiation from the heat exchanger component 30 on the air near the lower side of the main air inlet cavity 152, thereby reducing the influence of heat radiation from the heat exchanger component 30 on the auxiliary air inlet cavity 164. This makes the temperature detected by the room temperature sensor 40 located on the side wall of the auxiliary air inlet cavity 164 deviate less from the indoor temperature, thus reducing the temperature regulation error of the air conditioner.

[0092] refer to Figures 5-6 According to some embodiments of the present invention, the mounting part 16 includes a straight plate part 165 and an inclined plate part 166 arranged at an angle. The straight plate part 165 is connected between the inclined plate part 166 and the grille part 15. Both the straight plate part 165 and the grille part 15 extend in the vertical direction. The auxiliary air inlet 161 includes a first auxiliary air inlet 162 and a second auxiliary air inlet 163. The first auxiliary air inlet 162 is disposed on the straight plate part 165, and the second auxiliary air inlet 163 is disposed on the inclined plate part 166.

[0093] For example, indoor air can flow into the auxiliary air inlet 164 from the first auxiliary air inlet 162 of the straight plate 165 and pass through the room temperature sensor 40, or it can flow into the auxiliary air inlet 164 from the second auxiliary air inlet 163 of the inclined plate 166 and pass through the room temperature sensor 40. The air in the auxiliary air inlet 164 then flows into the main air inlet 152.

[0094] By setting the straight plate portion 165 and the inclined plate portion 166 at an angle, and placing the first auxiliary air inlet 162 on the straight plate portion 165 and the second auxiliary air inlet 163 on the inclined plate portion 166, indoor air can enter the auxiliary air inlet cavity 164 from different angles, thereby allowing airflow to pass through the room temperature sensor 40 from different directions, so that the room temperature sensor 40 can fully contact the indoor air, making the temperature detection of the room temperature sensor 40 more accurate.

[0095] refer to Figures 5-7According to some embodiments of the present invention, the auxiliary air inlet 161 includes a plurality of spaced-apart sub-air inlets. By including a plurality of spaced-apart sub-air inlets in the auxiliary air inlet 161, the amount of debris entering the housing 10 from the auxiliary air inlet 161 can be reduced. It also helps to increase the air intake area of ​​the auxiliary air inlet 161, thereby increasing the air intake volume of the auxiliary air inlet 161. This allows the temperature sensor at the auxiliary air inlet 161 to have sufficient contact with the indoor air, making the detected temperature of the room temperature sensor 40 closer to the actual indoor ambient temperature and reducing the detection deviation.

[0096] refer to Figure 7 According to some embodiments of the present invention, the air inlet grille 14 includes a partition rib 141, which is located between the main air inlet cavity 152 and the auxiliary air inlet cavity 164. The partition rib 141 is provided with a connecting hole 142, which is used to connect the main air inlet cavity 152 and the auxiliary air inlet cavity 164.

[0097] For example, indoor air flows into the auxiliary air intake cavity 164 from the auxiliary air intake 161, passes through the room temperature sensor 40, and then flows into the main air intake cavity 152 through the connecting hole 142.

[0098] By providing a partition rib 141 between the main air intake cavity 152 and the auxiliary air intake cavity 164, and providing a connecting hole 142 on the partition rib 141, the auxiliary air intake cavity 164 can be connected to the main air intake cavity 152, while reducing the influence of the airflow in the main air intake cavity 152 on the airflow temperature in the auxiliary air intake cavity 164, thereby making the indoor ambient temperature measured by the room temperature sensor 40 more accurate.

[0099] refer to Figure 7 According to some embodiments of this utility model, the connecting holes 142 are arranged in multiple spaces along the left-right direction. By arranging the connecting holes 142 in multiple spaces along the left-right direction, the airflow resistance of the auxiliary air inlet cavity 164 entering the main air inlet cavity 152 can be reduced, and the influence of the airflow in the main air inlet cavity 152 on the airflow temperature in the auxiliary air inlet cavity 164 can be reduced. This balances reducing airflow resistance and airflow influence, making the detected temperature of the room temperature sensor 40 closer to the actual indoor ambient temperature with a smaller deviation.

[0100] refer to Figure 7 According to some embodiments of the present invention, a notch is formed at one end of the partition rib 141 near the housing 13, and the notch forms a connecting hole 142. By forming a notch at one end of the partition rib 141 near the housing 13 and making the notch form a connecting hole 142, the processing of the partition rib 141 is facilitated.

[0101] refer to Figures 8-9According to some embodiments of this utility model, the room temperature sensor 40 is mounted on the housing 13 via a mounting bracket 50. The room temperature sensor 40 can be installed inside the mounting bracket 50, and the mounting bracket 50 can be installed inside the housing 13. By mounting the room temperature sensor 40 on the housing 13 via the mounting bracket 50, the installation and fixation of the room temperature sensor 40 is convenient.

[0102] According to some embodiments of this utility model, the mounting bracket 50 is detachably connected to the housing 13. This detachable connection facilitates the maintenance and replacement of the room temperature sensor 40.

[0103] According to some embodiments of this utility model, the room temperature sensor 40 is detachably connected to the mounting bracket 50. For example, when the room temperature sensor 40 malfunctions, it can be removed from the mounting bracket 50 and replaced with a new one. By making the room temperature sensor 40 detachably connected to the mounting bracket 50, the maintenance and replacement of the room temperature sensor 40 are facilitated, maintaining the accuracy of the temperature detected by the room temperature sensor 40.

[0104] refer to Figures 8-9 According to some embodiments of the present invention, the housing 13 is provided with a mounting port 132, which is located on the side wall of the auxiliary air inlet cavity 164. At least a portion of the room temperature sensor 40 is opposite to or located inside the mounting port 132.

[0105] For example, at least a portion of the room temperature sensor 40 may be opposite to or located within the mounting port 132. This could be a partial or complete arrangement of the room temperature sensor 40 within the mounting port 132, or the entire room temperature sensor 40 may be opposite to or entirely located within the mounting port 132. For instance, the room temperature sensor 40 may be fixed within the mounting port 132 by a mounting bracket 50.

[0106] When at least a portion of the room temperature sensor 40 is opposite to the mounting port 132, the air entering the auxiliary air intake cavity 164 from the auxiliary air intake port 161 can contact the room temperature sensor 40 through the mounting port 132; when the room temperature sensor 40 is located inside the mounting port 132, the air entering the auxiliary air intake cavity 164 from the auxiliary air intake port 161 can directly contact the room temperature sensor 40, thereby facilitating the room temperature sensor 40 to detect the temperature of the air entering the auxiliary air intake cavity 164.

[0107] By providing a mounting port 132 on the housing 13 and by positioning at least a portion of the room temperature sensor 40 opposite to or within the mounting port 132, the room temperature sensor 40 can be prevented from being exposed to the outside, thus protecting the room temperature sensor 40. It also facilitates fixing the room temperature sensor 40 to the side wall of the auxiliary air intake cavity 164, making it easier for the room temperature sensor 40 to measure the temperature of the air inside the auxiliary air intake cavity 164.

[0108] refer to Figures 10-11 According to some embodiments of the present invention, the mounting bracket 50 is formed with a receiving groove 53, the room temperature sensor 40 is received in the receiving groove 53, and a through hole 531 is formed on the groove wall of the receiving groove 53, the through hole 531 connects the receiving groove 53 and the auxiliary air inlet cavity 164.

[0109] For example, multiple through holes 531 can be formed on the wall of the receiving groove 53, and the multiple through holes 531 can be arranged at intervals in the left and right direction.

[0110] For example, after indoor air flows into the auxiliary air inlet 164 from the auxiliary air inlet 161, it can flow into the receiving groove 53 through the through hole 531 on the mounting bracket 50, so that it can come into contact with the room temperature sensor 40 located in the receiving groove 53.

[0111] By forming a receiving groove 53 on the mounting bracket 50 and accommodating the room temperature sensor 40 in the receiving groove 53, it is convenient to install and position the room temperature sensor 40, and it can also protect the room temperature sensor 40. Furthermore, by forming a through hole 531 on the groove wall of the receiving groove 53, the through hole 531 connects the receiving groove 53 and the auxiliary air inlet cavity 164, so that the room temperature sensor 40 can fully contact the indoor air entering the auxiliary air inlet cavity, making the temperature detection of the room temperature sensor 40 more accurate.

[0112] refer to Figures 10-11 According to some embodiments of this utility model, the mounting bracket 50 is provided with multiple wire clamps 54, which are arranged at intervals along the extension direction of the receiving groove 53. The wire clamps 54 are used to position the room temperature sensor 40 within the receiving groove 53. By using the wire clamps 54 to position the room temperature sensor 40 within the receiving groove 53, the room temperature sensor 40 can be prevented from falling out of the receiving groove 53, thus ensuring that the room temperature sensor 40 is stably fixed on the mounting bracket 50. This prevents the room temperature sensor 40 from falling off or deviating from its fixed position due to external forces such as pulling on the wiring, and also makes the temperature detection of the room temperature sensor 40 more accurate.

[0113] refer to Figures 10-11According to some embodiments of this utility model, the inner wall of the receiving groove 53 is provided with multiple sets of positioning ribs 532. The multiple sets of positioning ribs 532 are arranged at intervals along the extension direction of the receiving groove 53. Each set of positioning ribs 532 includes two positioning ribs 533 located on opposite sides of the room temperature sensor 40. By providing multiple sets of positioning ribs 532 arranged at intervals along the extension direction of the receiving groove 53 on the inner wall of the receiving groove 53, the room temperature sensor 40 housed in the receiving groove 53 can be further limited, making the room temperature sensor 40 more stably fixed in the receiving groove 53. This facilitates the installation of the room temperature sensor 40 and also helps to keep the room temperature sensor 40 in the same position for temperature measurement, making the detection of the actual indoor ambient temperature by the room temperature sensor 40 more accurate.

[0114] refer to Figures 10-12 According to some embodiments of the present invention, the room temperature sensor 40 includes a connected sensor harness 41 and a sensor probe 42, and the wire clamp 54 is offset from the sensor probe 42.

[0115] For example, the wire clamp 54 can be set at the sensor wire harness 41 to clamp the sensor wire harness 41.

[0116] By setting the wire clamp 54 and the sensor probe 42 out of alignment, damage to the sensor probe 42 due to force can be avoided, as well as data distortion caused by internal deformation of the sensor probe 42 under pressure. This makes the room temperature sensor 40 more accurate in detecting the actual indoor ambient temperature.

[0117] refer to Figure 12 According to some embodiments of the present invention, a protective sleeve 43 is provided on the outside of the room temperature sensor 40. The protective sleeve 43 has an opening. The room temperature sensor 40 includes a connected sensor harness 41 and a sensor probe 42. The sensor probe 42 is located inside the protective sleeve 43, and the sensor is arranged opposite to the opening.

[0118] By placing the sensor probe 42 inside the sheath 43, the sensor probe 42 can be protected from damage caused by external forces such as collisions. Furthermore, by making the sheath 43 have an opening, with the sensor positioned opposite the opening, air that enters the receiving groove 53 through the through hole 531 can enter the interior of the sheath 43 through the opening and come into contact with the sensor probe 42, making the detection of the actual indoor ambient temperature by the room temperature sensor 40 more accurate.

[0119] refer to Figures 10-11According to some embodiments of this utility model, the mounting bracket 50 includes a first bracket portion 51 and a second bracket portion 52 arranged at an angle. The room temperature sensor 40 includes a connected sensor harness 41 and a sensor probe 42. The sensor probe 42 is located in the first bracket portion 51, and at least a portion of the sensor harness 41 runs along the second bracket portion 52. The first bracket portion 51 is opposite to or located within the mounting opening 132. Both the first bracket portion 51 and the second bracket portion 52 have receiving grooves 53. Air entering the auxiliary air intake cavity from the auxiliary air inlet can enter the receiving groove 53 of the first bracket portion 51 through the mounting opening 132 and the through hole 531 on the mounting bracket 50. The air entering the receiving groove 53 of the first bracket portion 51 comes into contact with the sensor probe 42 mounted on the first bracket portion 51, thereby detecting the indoor ambient temperature.

[0120] For example, at least a portion of the sensor harness 41 may be routed along the second bracket portion 52, meaning that a portion of the sensor harness 41 may be routed along the second bracket portion 52.

[0121] For example, the sensor probe 42 is located in the first bracket portion 51, and the sensor harness 41 connected to the sensor probe 42 runs along the first bracket portion 51, then runs along the second bracket portion 52 and extends out to the mounting bracket 50.

[0122] By including a first bracket portion 51 and a second bracket portion 52 arranged at an angle in the mounting bracket 50, and by routing at least a portion of the sensor harness 41 along the second bracket portion 52, the sensor harness 41 can continue routing after turning an angle during routing, thereby making the sensor harness 41 more secure and preventing the sensor probe 42 from being dislodged from its original position when the sensor harness 41 is pulled by external force.

[0123] refer to Figures 13-14 According to some embodiments of the present invention, the mounting port 132 includes two first sidewalls 133 arranged opposite to each other in the vertical direction and two second sidewalls 134 arranged opposite to each other in the horizontal direction. The mounting bracket 50 is provided with first buckles 55 at both ends in the horizontal direction and with limiting ribs 57 on both sides in the vertical direction. The first buckles 55 are engaged with the second sidewalls 134 and the limiting ribs 57 are abutted against the first sidewalls 133.

[0124] For example, the mounting bracket 50 can be provided with a first buckle 55 at each end along the left and right directions. When the mounting bracket 50 is installed in the mounting port 132, the mounting bracket 50 is pushed towards the mounting port 132 in the front and back directions, so that the two first buckles 55 are engaged with the two second side walls 134 respectively, and the limiting rib 57 abuts against the first side wall 133 to fix the mounting bracket 50.

[0125] By engaging the first buckle 55 with the second sidewall 134, the mounting bracket 50 can be fixed to the mounting opening 132. The limiting rib 57 abuts against the first sidewall 133, which can improve the stability of the mounting bracket 50 installed in the mounting opening 132 and prevent the mounting bracket 50 from loosening or shaking under the airflow, thereby preventing the room temperature sensor 40 from deviating from the temperature measuring position and making the room temperature sensor 40 detect the actual indoor ambient temperature more accurately.

[0126] refer to Figures 15-16 According to some embodiments of the present invention, the housing 13 is provided with a card hole 135, and the mounting bracket 50 is provided with a second buckle 56 at both ends along the vertical direction. The second buckle 56 is inserted into the card hole 135 along the front-back direction.

[0127] For example, the mounting bracket 50 can be provided with a second buckle 56 at each end along the vertical direction, and the housing 13 can be provided with two locking holes 135. The two locking holes 135 are spaced apart along the vertical direction. When the mounting bracket 50 is installed in the mounting port 132, the mounting bracket 50 is pushed towards the mounting port 132 along the front-back direction, so that the two second buckles 56 are respectively locked into the two locking holes 135 to fix the mounting bracket 50.

[0128] By providing a snap hole 135 on the housing 13 and a snap fastener on the mounting bracket 50 to fix the mounting bracket 50 to the housing 13, the installation and removal of the mounting bracket 50 is made more convenient, and the room temperature sensor 40 is easier to inspect and maintain.

[0129] refer to Figure 17 According to some embodiments of the present invention, the mounting bracket 50 is provided with connecting holes 58 at both ends along the vertical direction, and the connecting holes 58 are connected to the housing 13 by fasteners.

[0130] For example, the connection hole 58 can be connected to the housing 13 by screws.

[0131] By providing connection holes 58 at both ends of the mounting bracket 50 along the vertical direction and connecting the connection holes 58 to the housing 13 with fasteners, the mounting bracket 50 and the housing 13 can be more firmly fixed, preventing the mounting bracket 50 from falling off the housing 13, thereby making the temperature sensor more stable and reducing the risk of falling off.

[0132] refer to Figures 3-4 According to some embodiments of the present invention, the auxiliary air inlet 161 is located below the grille 15, and the air conditioner also includes a water receiving tray 60, which is located below the heat exchanger component 30. The vent 131 is located on the rear side wall of the housing 13, and a sealing element 70 is provided between the water receiving tray 60 and the rear side wall of the housing 13. The sealing element 70 is located above the room temperature sensor 40.

[0133] By placing the auxiliary air inlet 161 below the grille section 15, the temperature sensor can be easily inspected and maintained. The water collection tray 60 is positioned below the heat exchanger component 30 to facilitate the collection of condensate generated during cooling, preventing it from dripping onto live components inside the air conditioner and causing a short circuit, thus improving the air conditioner's safety. Furthermore, the sealing element 70 between the water collection tray 60 and the rear wall of the housing 13 provides insulation, reducing heat radiation from the heat exchanger component 30 to the temperature sensor. This reduces the deviation between the temperature detected by the room temperature sensor 40 and the actual indoor temperature, resulting in smaller temperature regulation errors and more precise control of the indoor temperature. The sealing element 70 also provides a water-proof effect, preventing condensate generated on the outer wall of the water collection tray 60 from dripping down onto the temperature sensor through the gap between the water collection tray 60 and the housing 13.

[0134] According to some embodiments of this utility model, the sealing element 70 is a sponge. By making the sealing element 70 a sponge, and utilizing the characteristic that the interior of the sponge is filled with a large number of tiny pores, the sponge has a good heat insulation effect and can absorb water, thereby reducing the heat radiation from the heat exchanger component 30 to the temperature sensor.

[0135] refer to Figures 3-7 According to some embodiments of the present invention, the air inlet grille 14 includes a partition rib 141, which is located between the main air inlet cavity 152 and the auxiliary air inlet cavity 164. The partition rib 141 is provided with a connecting hole 142, which is used to connect the main air inlet cavity 152 and the auxiliary air inlet cavity 164. The partition rib 141 is arranged opposite to the sealing member 70 in the front-back direction.

[0136] By providing a partition rib 141 between the main air inlet cavity 152 and the auxiliary air inlet cavity 164, and providing a connecting hole 142 on the partition rib 141, the auxiliary air inlet cavity 164 can be connected to the main air inlet cavity 152, while reducing the influence of the airflow in the main air inlet cavity 152 on the airflow temperature in the auxiliary air inlet cavity 164, thereby making the temperature measurement of the room temperature sensor 40 more accurate. Furthermore, by arranging the partition rib 141 opposite to the sealing member 70 in the front-rear direction, the heat radiation from the heat exchanger component 30 to the partition rib 141 can be reduced, thereby reducing the temperature radiation influence of the heat exchanger component 30 on the temperature sensor, making the detected temperature of the room temperature sensor 40 closer to the actual indoor ambient temperature.
