[0041] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.
[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0043] Combination Figure 1-6 As shown, this disclosure provides an indoor unit, including a housing 10 and a sensor assembly.
[0044] The housing 10 defines an air outlet duct and is provided with an air inlet 101 and an air outlet 102 that are connected to the air outlet duct.
[0045] The sensor assembly includes at least one of a refrigerant leak sensor, a humidity sensor, and an ambient temperature sensor.
[0046] Among them, such as Figure 1 As shown, the sensor assembly is located at the air inlet 101.
[0047] On the one hand, there is airflow at the air inlet 101. Therefore, after multiple tests, placing the sensor assembly at the air inlet 101 has a good detection effect, and the sensor assembly does not occupy the internal space of the indoor unit. On the other hand, placing the sensor assembly at the air inlet 101 makes it convenient to maintain the sensor assembly.
[0048] Optionally, the sensor assembly is located along the length of the air inlet 101 (e.g., Figure 1 The middle part (in the left and right directions).
[0049] The sensor assembly is located in the middle of the length of the air inlet 101, for example, at the center of the length. This allows the sensor assembly to detect the surrounding air conditions more evenly, improving detection accuracy and stability.
[0050] Optionally, such as Figure 1 As shown, the sensor assembly is offset from the width direction of the air inlet 101 (e.g.) Figure 1 The middle setting (in the top and bottom directions).
[0051] Optionally, such as Figure 1 As shown, the air inlet 101 includes a first end 106 and a second end 107 along the width direction. The distance between the first end and the air outlet 102 is greater than the distance between the second end and the air outlet 102. The sensor assembly is located at the first end.
[0052] The sensor assembly is located at the first end of the air inlet 101, which is far from the air outlet 102. This avoids the airflow from the air outlet 102 mixing with the airflow at the second end, which would affect the detection results of the sensor assembly.
[0053] Optionally, the indoor unit also includes an air intake grille, which is located at the air inlet 101, and the sensor assembly is located inside the air intake grille.
[0054] The air inlet grille and sensor assembly are arranged sequentially along the airflow direction. The air inlet grille not only protects the sensor assembly but also does not obstruct the sensor assembly from detecting data.
[0055] The air intake grille is detachable. When it is necessary to repair or replace the sensor assembly, the air intake grille can be removed and the sensor assembly can be taken out.
[0056] Optionally, such as Figure 1 As shown, the indoor unit also includes a water tray 103, which is disposed in the air inlet 101 and extends along the length of the air inlet 101 to divide the air inlet 101 into a first sub-air inlet 104 and a second sub-air inlet 105. The sensor assembly is disposed in the first sub-air inlet 104 or the second sub-air inlet 105.
[0057] The first sub-air inlet 101 and the second sub-air inlet 105 are arranged sequentially along the width direction of the air inlet 101. The sensor assembly is located in one of the first sub-air inlets 104 and the second sub-air inlet 105, so that the sensor assembly is located within a local area of the air inlet 101, the airflow at the location of the sensor assembly is more stable, and the detection results are more accurate.
[0058] Along the direction from the air inlet 101 to the air outlet 102, the first sub-air outlet 104 and the second sub-air outlet 105 are arranged in sequence. The sensor assembly is located in the first sub-air outlet 104 to avoid the airflow at the air outlet 102 affecting the detection results of the sensor assembly.
[0059] Optionally, the indoor unit also includes an indoor heat exchanger, which is located inside the air duct, and the air inlet 101 is located below the indoor heat exchanger.
[0060] Optionally, the air conditioner is a recessed air conditioner, with the air outlet 102 also located below the indoor heat exchanger. The air inlet 101 and air outlet 102 are located on the bottom wall of the indoor unit, both extending along the length of the bottom wall. When the indoor unit is installed, air enters the duct from the bottom air inlet, flows upward to the indoor heat exchanger, exchanges heat with the heat exchanger, and then flows downward to the air outlet, exiting from the outlet. The air flows along the width of the bottom wall of the indoor unit (e.g., along the width of the bottom wall). Figure 1 (In the vertical direction), the air inlet 101 and the air outlet 102 are set in sequence.
[0061] The most common location for refrigerant leaks in the indoor unit is at the pipe joints of the indoor heat exchanger. When a refrigerant leak occurs, because the density of the refrigerant is greater than that of air, it will sink under its own gravity. The air inlet 101 is located below the indoor heat exchanger, allowing the leaked refrigerant to settle at the air inlet 101. When the sensor assembly includes a refrigerant leak sensor, it can detect the leaking refrigerant in a timely manner.
[0062] Optionally, such as Figure 5 and Figure 6 As shown, the indoor unit also includes a water tray 103 and a bracket 20. The water tray 103 is located below the indoor heat exchanger and is used to collect the condensate produced by the indoor heat exchanger.
[0063] The support 20 includes a support body 201, which is connected to the water receiving tray 103, and the sensor assembly is located on the support body 201.
[0064] The sensor assembly is located on the frame body 201, and the frame body 201 is located on the water receiving tray 103, thereby realizing the installation and fixation of the sensor assembly in the indoor unit.
[0065] When the sensor assembly includes a refrigerant leak sensor, the refrigerant leaking from the indoor heat exchanger can fall into the drip tray 103 under its own gravity. The sensor assembly is positioned close to the drip tray 103, thereby being able to detect the refrigerant in the drip tray 103, so that the refrigerant leak sensor can detect the leaked refrigerant in a timely manner.
[0066] The sensor assembly includes multiple sensors, and the bracket 20 includes a bracket body 201 with multiple mounting positions, one sensor being mounted at one mounting position. At least two of the multiple mounting positions are not located in the same plane.
[0067] like Figure 6 As shown, the frame body 201 has multiple mounting positions, each for mounting one sensor. This design allows the sensors to be centrally mounted on the frame body 201, simplifying the installation and maintenance process for each sensor.
[0068] At least two of the multiple mounting positions are not located in the same plane. This avoids the problem of the frame body 201 being too large along the plane direction due to two mounting positions being in the same plane. This allows the multiple mounting positions to make full use of the space in each direction of the frame body 201, making the structure of the bracket 20 more compact.
[0069] Optionally, such as Figure 6 As shown, the multiple mounting positions include a first mounting position 202 and a second mounting position 203, with the second mounting position 203 and the first mounting position 202 respectively located on opposite sides of the frame body 201.
[0070] The sensor located at the first mounting position 202 is named the first sensor 301, and the sensor located at the second mounting position 203 is named the second sensor 302.
[0071] like Figure 4As shown, the first sensor 301 and the second sensor 302 are respectively located on opposite sides of the frame body 201. This design optimizes the layout of the first sensor 301 and the second sensor 302, ensuring that the first sensor 301 and the second sensor 302 do not interfere with each other, while improving the comprehensiveness and accuracy of the detection by the first sensor 301 and the second sensor 302.
[0072] Optionally, such as Figure 6 As shown, the face where the first mounting position 202 is located is not parallel to the face where the second mounting position 203 is located.
[0073] This design increases the distance between the first sensor 301 and the second sensor 302, ensuring that the first sensor 301 and the second sensor 302 do not interfere with each other and improving the detection effect.
[0074] Optionally, the surface where the first mounting position 202 is located is perpendicular to the surface where the second mounting position 203 is located.
[0075] The orientation difference between the plane where the first mounting position 202 is located and the plane where the second mounting position 203 is located is significant. Therefore, after the first sensor 301 and the second sensor 302 are installed on the frame body 201, the orientation difference between the planes where the first sensor 301 and the second sensor 302 are located is also significant. Since the first sensor 301 and the second sensor 302 are different types of sensors, the first mounting position 202 can fully consider the detection parameters of the first sensor 301, and the second mounting position 203 can fully consider the detection parameters of the second sensor 302. This ensures that even with a significant difference in the detection parameters of the first sensor 301 and the second sensor 302, both sensors can achieve relatively accurate detection results. In other words, the significant orientation difference between the planes where the first mounting position 202 and the second mounting position 203 are located allows for the installation of sensors with significantly different detection parameters (the first sensor 301 and the second sensor 302, respectively) at the first mounting position 202 and the second mounting position 203, enabling the sensor assembly to detect various parameters.
[0076] Optionally, one of the refrigerant leak sensor, humidity sensor, and ambient temperature sensor is located at the first mounting position 202, and the other of the refrigerant leak sensor, humidity sensor, and ambient temperature sensor is located at the second mounting position 203.
[0077] For example, the first sensor 301 is a humidity sensor used to detect the air humidity at its location, and the second sensor 302 is a refrigerant leak sensor used to detect whether the indoor unit is leaking refrigerant.
[0078] like Figure 1 and Figure 6As shown, the first mounting position 202 extends along the surface where the air inlet 101 is located, so that the first mounting position 202 occupies a large area on the surface where the air inlet 101 is located, thereby accurately obtaining the humidity of the air at the air inlet 101; the second mounting position 203 extends in a direction perpendicular to the surface where the air inlet 101 is located, so that the second mounting position 203 can be as close as possible to the indoor heat exchanger, so that the refrigerant leakage sensor can quickly obtain the refrigerant leakage situation of the indoor heat exchanger.
[0079] Optionally, such as Figure 6 As shown, the multiple mounting positions also include a third mounting position 204, which is located between the first mounting position 202 and the second mounting position 203.
[0080] The sensor located at the third mounting position 204 is named the third sensor 303.
[0081] The third mounting position 204 allows for the addition of a third sensor 303 to the frame body 201, increasing the types of detection information.
[0082] like Figure 6 As shown, the third mounting position 204 is located between the first mounting position 202 and the second mounting position 203, making the structure of the frame body 201 more compact and increasing the number of sensors that can be installed within the limited space of the frame body 201.
[0083] Optionally, the frame body 201 also has a third mounting position 204, where another one of the refrigerant leak sensor, humidity sensor, and ambient temperature sensor is located. For example, the third sensor 303 is an ambient temperature sensor used to detect the ambient temperature.
[0084] The third mounting position 204 is located on the side of the frame body 201 facing the air inlet 101. In this way, after the third sensor 303 is installed in the third mounting position 204, it can accurately obtain the ambient temperature.
[0085] Optionally, such as Figure 6 As shown, the bracket 20 also includes a limiting rib 205, which is provided on the bracket body 201 and surrounds the edge of the mounting position, and the sensor is limited within the limiting rib 205.
[0086] The limiting rib 205 is set around the edge of the mounting position, and the space formed by the limiting rib 205 is adapted to the sensor located in the mounting position, ensuring that the sensor is firmly installed in the mounting position.
[0087] For example, Figure 4As shown, the limiting rib 205 is arranged around the edge of the first mounting position 202. The limiting rib 205 is in the shape of a ring and extends along the circumference of the first mounting position 202. The limiting rib 205 may not be in the shape of a ring. In this case, there may be multiple limiting ribs 205, and multiple limiting ribs 205 are arranged sequentially along the circumference of the first mounting position 202.
[0088] The sensor is snapped into the frame body 201.
[0089] The sensor is connected to the frame body by screws 201 and 50.
[0090] Both snap-fit and / or screw 50 connections are detachable, facilitating sensor disassembly and maintenance.
[0091] like Figure 4 As shown, the limiting rib 205 is provided with a first buckle 206 at one end away from the frame body 201. The first buckle 206 abuts against the surface of the first sensor 301 away from the first mounting position 202 to achieve the snap-fit positioning of the first sensor 301.
[0092] like Figure 4 As shown, the second sensor 302 is connected to the frame body 201 by screws 50.
[0093] like Figure 6 As shown, the surface of the third mounting position 204 is provided with a second buckle 207. The second buckle 207 includes a first sub-buckle 208 and a second sub-buckle 209. The first sub-buckle 208 and the second sub-buckle 209 are arranged opposite to each other and together enclose a snap-fit space 210. The third sensor 303 passes through the limiting space to realize the snap-fit limiting of the third sensor 303 by the second buckle 207.
[0094] Optionally, such as Figure 4 As shown, the frame body 201 is provided with a storage part 211 for storing the wiring terminal 214, wherein the wiring terminal 214 is used to connect to the sensor.
[0095] When the sensor needs to be installed or is in place, connect the terminal block 214 to the sensor to connect the sensor to the air conditioner's computer board, thereby enabling communication between the sensor and the computer board. When the sensor is not needed or is removed from the frame body 201, the terminal block 214 can be stored in the storage part 211 to protect the terminal block 214 and prevent water or dust from entering it.
[0096] The computer board is located inside the electrical control box 40, which is located on the outer side of the end of the air inlet 101 along its length. The sensor assembly is located at the air inlet 101, which also facilitates the wiring between the sensor assembly and the computer board.
[0097] For example, refrigerant leak sensors are expensive and can be selected by users. If users do not need to install refrigerant leak sensors, the terminal 214 connected to the refrigerant leak sensor can be stored in the storage part 211 to prevent the terminal 214 from being exposed for a long time and easily getting water and dust in.
[0098] Optionally, such as Figure 4 As shown, the storage section 211 includes a storage hole 212 for mounting the wiring terminal 214.
[0099] The storage hole 212 is compatible with the terminal block 214. Inserting the terminal block 214 into the storage hole 212 can fix the terminal block 214 and prevent it from becoming loose or falling off.
[0100] Optionally, the storage part 211 includes a storage protrusion 213, which is disposed on the frame body 201, and a storage hole 212 is disposed on the storage protrusion 213.
[0101] The storage protrusion 213 protrudes from the frame body 201. The storage protrusion 213 is designed as a storage part 211, which can affect the setting of the first to third mounting positions 204 on the frame body 201.
[0102] The frame body 201 is provided with a wiring harness 215, which is used to fix the sensor wiring. The wiring harness 215 is located on the surface of the frame body 201 facing the air inlet 101, that is, on the surface of the wiring harness 215 away from the water receiving tray 103. In this way, after the sensor wiring passes through the wiring harness 215, it can extend along the side wall of the air inlet 101 to the computer board and connect to the computer board.
[0103] like Figure 6 As shown, the wiring section 215 includes a wiring groove 216 through which the sensor wiring passes.
