Description

Technical Field

[0002] An air conditioner is a device that uses a refrigeration cycle to control the temperature, humidity, and air supply of the indoor environment. The main components that form the refrigeration cycle include a compressor, a heat exchanger (condenser, evaporator), and a fan.

[0003] An outdoor ambient temperature sensor is usually installed on the air inlet side of the air conditioner outdoor unit, and the air conditioner controls its operation according to the detection value of the outdoor ambient temperature sensor. In view of the current limitations of refrigeration and heat exchange technology, when the outdoor ambient temperature reaches 55 degrees Celsius or above, the air conditioner can only maintain low-frequency operation or directly shut down for protection, which cannot meet the user's cooling needs. Therefore, a spray device is installed on the outdoor unit of some air conditioners to spray water on the outdoor heat exchanger, and use the evaporative cooling of water to reduce the temperature of the outdoor heat exchanger, thereby ensuring that the air conditioner can still operate normally when the outdoor ambient temperature is high.

[0004] When the sprinkler sprays water onto the outdoor heat exchanger, the water mist is likely to splash onto the outdoor ambient temperature sensor, causing the temperature collected by the sensor to be inaccurate. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0029] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0030] The terms "first", "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0033] The compressor compresses the refrigerant gas in a low temperature and low pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0034] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0035] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0036] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0037] Reference Figure 1 and Figure 2 According to some embodiments of the present application, the air conditioner outdoor unit includes a housing 10, in which a plurality of components constituting a refrigeration cycle are installed. The housing 10 includes a top cover 11 defining a top structure, a bottom plate defining a bottom structure, and four side plates connected between the top cover 11 and the bottom plate. Among them, the side plate located at the rear side of the four side plates is called a first side plate 13.

[0038] The top cover 11 includes a top wall and side walls connected around the top wall. The top cover 11 is arranged on the top ends of the four side walls.

[0039] An air inlet 131 is disposed on the first side plate 13 , and the air inlet 131 can expose most of the outdoor heat exchanger 20 .

[0040] An outdoor heat exchanger 20 is installed in the casing 10 . The outdoor heat exchanger 20 is disposed corresponding to the air inlet 131 . The outdoor heat exchanger 20 performs heat exchange with the air sucked in through the air inlet 131 .

[0041] The outdoor heat exchanger 20 can be a fin-type heat exchanger, which specifically includes a refrigerant pipe arranged in an S-shape and fins inserted into the refrigerant pipe. The refrigerant pipe is connected to the refrigerant pipe of the indoor heat exchanger through a pipeline, and is mainly used to circulate the refrigerant. The heat on the refrigerant pipe will be transferred to the fins, and the fins are mainly used to exchange heat with the air passing through it.

[0042] Reference Figure 4 and Figure 5The outdoor heat exchanger 20 is provided with an end plate 21 at the transverse end thereof for fixing the fins. The edge of the end plate 21 may be provided with a folded edge 211. The folded edge 211 abuts against the first side plate 13, and then the folded edge 211 may be fixed to the first side plate 13 by screws, thereby achieving a fastened connection of the outdoor heat exchanger 20 in the housing 10.

[0043] The end plate 21 may be a sheet metal part, and the folded edge 211 is formed by bending the edge of the end plate 21 .

[0044] Continue to refer to Figure 1 The air conditioner outdoor unit includes a spray device 30, which can be installed on the top cover 11 or the outer wall, and is used to spray water from the air inlet 131 onto the outdoor heat exchanger 20 to cool the outdoor heat exchanger 20 by evaporative cooling of water.

[0045] The pipeline of the spray device 30 is connected to an external water source, and the nozzle 31 of the spray device 30 is directed toward the outdoor heat exchanger 20. When the pipeline is flowing, water is sprayed onto the windward surface of the outdoor heat exchanger 20 through the nozzle 31.

[0046] Reference Figure 2 , Figure 3 The air conditioner outdoor unit includes an outdoor ambient temperature sensor 40. The outdoor ambient temperature sensor 40 is connected to the edge of the air inlet 131 and is located on the windward side of the outdoor heat exchanger 20 to detect the temperature of the outdoor environment.

[0047] An outwardly protruding portion is provided on the edge of the first side plate 13 close to the air inlet 131 , and an accommodating cavity 132 is formed inside the protruding portion. Part of the outdoor ambient temperature sensor 40 is located in the accommodating cavity 132 .

[0048] The outdoor ambient temperature sensor 40 can be divided into a mounting portion 46 installed in the accommodating cavity 132 and a sensing portion 47 exposed outside the accommodating cavity 132. The sensing portion 47 of the outdoor ambient temperature sensor 40 corresponds to the air inlet 131.

[0049] In some embodiments, reference Figure 5 The mounting portion 46 of the outdoor ambient temperature sensor 40 is connected to the folded edge 211. The bottom surface 44 of the mounting portion 46 is provided with a claw 45 extending outward, and the folded edge 211 is provided with a slot 212, and the claw 45 is engaged in the slot 212, so as to realize the connection between the outdoor ambient temperature sensor 40 and the outdoor heat exchanger 20.

[0050] In other embodiments, a mounting hole may be provided on the mounting portion 46 of the outdoor ambient temperature sensor 40 , and fasteners such as screws may be passed through the mounting hole and the folded edge 211 , thereby achieving screw connection between the outdoor ambient temperature sensor 40 and the outdoor heat exchanger 20 .

[0051] In other embodiments, the outdoor ambient temperature sensor 40 may also be connected to the housing 10. The outdoor ambient temperature sensor 40 may be connected to the first side plate 13 by fasteners such as screws.

[0052] When the air conditioner outdoor unit is working, the outdoor air can be detected by the outdoor ambient temperature sensor 40 when it flows through the air inlet 131. When the outdoor ambient temperature sensor 40 detects that the outdoor temperature is high, the spray device 30 is turned on to spray water onto the outdoor heat exchanger 20.

[0053] When the spray device 30 sprays water outward, the water is likely to splash onto the outdoor ambient temperature sensor 40 , which may affect the detection accuracy of the outdoor ambient temperature sensor 40 .

[0054] Therefore, in order to prevent water from directly dripping onto the sensor and affecting the temperature sensing accuracy, the present application provides a sheath 50 for the outdoor ambient temperature sensor 40 .

[0055] According to the embodiments of the present application, referring to Figure 6 and Figure 7 The sensing portion 47 of the outdoor ambient temperature sensor 40 may be substantially in the shape of a rectangular parallelepiped. The sensing portion 47 has a first side surface 41 facing the outdoor heat exchanger 20, a second side surface 42 facing away from the outdoor heat exchanger 20 (opposite to the first side surface 41), a top surface 43 connected to the top ends of the first side surface 41 and the second side surface 42, and a bottom surface 44 connected to the bottom ends of the first side surface 41 and the second side surface 42. The detection portion of the outdoor ambient temperature sensor 40 may be located on the second side surface 42.

[0056] Reference Figures 8 to 11 The sheath 50 is sleeved on the outside of the outdoor ambient temperature sensor 40 to prevent water from spraying onto the outdoor ambient temperature sensor 40 .

[0057] The sheath 50 surrounds the outside of the sensing portion 47, and has a top wall 51, a bottom wall 52, a first side wall 53 facing the outdoor heat exchanger 20, and a second side wall 54 facing away from the outdoor heat exchanger 20. The top wall 51 blocks the top surface 43 of the outdoor ambient temperature sensor 40 from above, the bottom wall 52 blocks the bottom surface 44 of the outdoor ambient temperature sensor 40 from below, the first side wall 53 blocks the first side surface 41 of the outdoor ambient temperature sensor 40, and the second side wall 54 blocks the second side surface 42 of the outdoor ambient temperature sensor 40.

[0058] In some embodiments, a notch 55 is disposed on the sheath 50 , and the notch 55 passes through the first side wall 53 , so that the sheath 50 is not closed in a direction surrounding the outdoor ambient temperature sensor 40 .

[0059] When the sheath 50 is sleeved on the outdoor ambient temperature sensor 40 , the notch 55 is expanded. After assembly, the sheath 50 forms a tightening force on the outdoor ambient temperature sensor 40 , so that the sheath 50 will not fall off the outdoor ambient temperature sensor 40 easily.

[0060] In other embodiments, the notch portion 55 may also be selectively disposed on the bottom wall 52 of the sheath 50 .

[0061] Since the detection part of the outdoor ambient temperature sensor 40 is mainly located on the second side surface 42 away from the outdoor heat exchanger 20, the notch 55 cannot be set on the second side wall 54 of the sheath 50, otherwise, moisture will enter the sheath 50 through the notch 55 on the second side wall 54 and contact the detection part of the outdoor ambient temperature sensor 40.

[0062] The notch 55 cannot be provided on the top wall 51 of the sheath 50 , otherwise moisture will enter the sheath 50 from the notch 55 at the top and flow downwards, possibly contacting the detection part of the outdoor ambient temperature sensor 40 .

[0063] The present application can prevent the water sprayed by the spray device 30 from contacting the detection part of the outdoor ambient temperature sensor 40 and affecting the detection accuracy of the sensor by providing a sheath 50 that is sleeved on the outdoor ambient temperature sensor 40. A notch 55 is provided on the sheath 50, so that the sheath 50 is not closed in the circumferential direction, so that the sheath 50 can be expanded when sleeved on the outdoor ambient temperature sensor 40, and the sheath 50 is ensured not to fall off easily by the tightening force.

[0064] The present application only requires the sheath 50 to be put on the outdoor ambient temperature sensor 40 , which is simple to operate, has a simple structure and is relatively low in cost.

[0065] According to an embodiment of the present application, an end portion of the sheath 50 perpendicular to the sheathing direction is open, for example, the right end of the sheath 50 is open, to form an inlet portion 56 .

[0066] The inner wall surface of the first side wall 53 is a smooth plane and has an installation guide function, and the first side wall 53 is also called a guide portion. During assembly, the outdoor ambient temperature sensor 40 enters from the inlet portion 56 side and is installed into the sheath 50 along the guide portion.

[0067] The guide portion may include a first guide portion 531 and a second guide portion 532. The top end of the first guide portion 531 is connected to the top wall 51, and the bottom end of the second guide portion 532 is connected to the bottom wall 52. The gap 55 is formed between the bottom end of the first guide portion 531 and the top end of the second guide portion 532.

[0068] The end of the guide portion near the entrance portion 56 is rounded, which can effectively avoid jamming and scratching during assembly, so that the sheath 50 can be smoothly put on the outdoor ambient temperature sensor 40. The edge of the guide portion can be bent outward to form a rounded corner.

[0069] In some embodiments, the edge of the inlet portion 56 is provided with an inwardly protruding anti-slip portion 57. For example, the sheath 50 can be made of sheet metal, and the inlet end (right end) of the top wall 51 and / or the bottom wall 52 of the sheath 50 is bent inwardly by 180° to form the anti-slip portion 57.

[0070] In the assembled state, the anti-detachment portion 57 abuts against the right side surface of the temperature sensing portion 47 . Due to the provision of the anti-detachment portion 57 , the sheath 50 can be prevented from detaching from the outdoor ambient temperature sensor 40 .

[0071] In some embodiments, a stopper 58 is provided at one end of the sheath 50 opposite to the inlet 56 , and the stopper 58 abuts against the left end surface of the outdoor ambient temperature sensor 40 .

[0072] The sensing portion 47 of the outdoor ambient temperature sensor 40 is limited between the anti-detachment portion 57 and the stopper portion 58 .

[0073] The stopper 58 may be cantilevered so that the stopper 58 has a certain deformation space to meet the installation requirements of the outdoor ambient temperature sensor 40 of different lengths in the left and right directions.

[0074] The stopper 58 can be connected to the left end of the guide portion. Specifically, the left end edge of the guide portion is bent to form the stopper 58.

[0075] The stopper 58 may include a first extension arm 581 having opposite first and second ends. The first end of the first extension arm 581 is connected to the guide portion. In the direction from the first end to the second end, the first extension arm 581 extends obliquely toward the inner side of the sheath.

[0076] The stopper 58 may include a second extension arm 582 connected to a second end of the first extension arm 581, and the first extension arm 581 extends away from the first extension arm 581 toward the outside of the sheath 50. The first extension arm 581 and the second extension arm 582 form a "V" shape.

[0077] Reference Fig.12 For one type of outdoor ambient temperature sensor 40 , there is a distance between the left end portion of the sensing portion 47 and the guide portion, and the end surface of the outdoor ambient temperature sensor 40 abuts against the second extension arm 582 .

[0078] Reference Fig.13For another type of outdoor ambient temperature sensor 40 , the left end of the sensing portion 47 abuts against the guide portion, and the connection portion between the first extension arm 581 and the second extension arm 582 abuts against the end face of the outdoor ambient temperature sensor 40 .

[0079] Therefore, the structure of the stopper 58 of the present application can adapt to outdoor ambient temperature sensors 40 of different structural types, and has the advantage of wide versatility.

[0080] In some embodiments, the second side wall 54 of the sheath 50 includes a first wall portion 541 , and the first wall portion 541 is inclined from top to bottom in a direction away from the outdoor ambient temperature sensor 40 .

[0081] The inclined setting of the first wall portion 541 can form a space between the first wall portion 541 and the outdoor ambient temperature sensor 40. The space can be used to circulate air, so that the air around the sensor can circulate effectively and the ambient temperature can be accurately collected. In addition, the inclined setting of the first wall portion 541 is conducive to drainage while blocking water.

[0082] The second side wall 54 of the sheath 50 includes a second wall portion 542, and the second wall portion 542 is connected to the bottom end of the first wall portion 541. From top to bottom, the second wall portion 542 is inclined toward the direction close to the outdoor ambient temperature sensor 40.

[0083] A triangular ventilation area is formed between the second wall portion 542 and the first wall portion 541 , which is beneficial to the circulation of air on the one hand, and on the other hand, moisture can flow downward smoothly under the guidance of the first wall portion 541 and the second wall portion 542 to avoid moisture accumulation on the sheath 50 .

[0084] In the present application, by putting the sheath 50 on the outside of the outdoor ambient temperature sensor 40, water can be blocked from spraying onto the outdoor ambient temperature sensor 40, thereby ensuring the detection accuracy of the outdoor ambient temperature sensor.

[0085] In the present application, a notch 55 is provided on the sheath 50 so that the sheath 50 is not closed in the circumferential direction, so that the sheath 50 can be expanded when it is sleeved on the outdoor ambient temperature sensor 40, and the tightening force is relied upon to ensure that the sheath 50 will not fall off easily.

[0086] In the present application, it is only necessary to put the sheath 50 on the outdoor ambient temperature sensor 40, which is simple to operate, has a simple structure, and is relatively low in cost.

[0087] In the present application, by providing an anti-detachment portion 57 that abuts against the end surface of the outdoor ambient temperature sensor 40 on the inlet portion 56 side of the sheath 50 , the sheath 50 can be effectively prevented from detaching from the outdoor ambient temperature sensor 40 .

[0088] In the present application, a stopper 58 is provided at one end of the sheath 50 opposite to the entrance 56 , and the outdoor ambient temperature sensor 40 is clamped by the anti-detachment part 57 and the stopper 58 , so that the firmness of the sheath 50 on the sensor 40 can be ensured.

[0089] In the present application, the stopper 58 is configured to be cantilevered so that the stopper 58 has a certain deformation space to meet the installation requirements of outdoor ambient temperature sensors 40 of different lengths.

[0090] In the present application, the stopper 58 includes a first extension arm 581 and a second extension arm 582 connected in a “V” shape, so that the stopper 58 can limit the position of sensors of two different structural forms, thereby increasing the use range of the sheath 50.

[0091] In the present application, the second side wall 54 of the sheath 50 is arranged at an inclination, so that a space can be formed between the second side wall 54 and the outdoor ambient temperature sensor 40. The space can be used to circulate air, so that the air around the sensor can circulate effectively and the ambient temperature can be accurately collected. In addition, the inclination of the first wall part 541 is not only conducive to water retention, but also to drainage.
