Description

[0002] There are a large number of refrigerant pipelines and valves in air conditioners, especially in outdoor units, including various valve bodies such as four-way valves, one-way valves, and electronic expansion valves. The four-way valve assembly includes the valve body, S tube, C tube, E tube, and D tube, which is a relatively heavy component in the entire pipeline. Especially for outdoor units with larger air conditioner capacities, the four-way valve selection and pipe diameter are also correspondingly larger, resulting in a heavier weight for the four-way valve assembly. At present, due to the limited internal space of the air conditioner outdoor unit, the connecting pipeline of the four-way valve assembly cannot be fixed on the bottom plate or frame. The connecting pipeline of the four-way valve assembly lacks constraints. During transportation, the connecting pipeline of the four-way valve assembly is prone to shaking, and the pipeline is prone to vibration and breakage, causing refrigerant leakage and affecting the normal use of the air conditioner.

[0003] In view of this, this application is filed. Utility Model Content

[0072] 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.

[0073] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0074] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0075] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0076] The air-conditioning outdoor unit provided in the embodiments of the present application may have various implementation forms, for example, it may be an outdoor unit of an air source heat pump unit, an outdoor unit of a wall-mounted air conditioner, an outdoor unit of a vertical air conditioner, etc. Figure 1 and Figure 2 This is a specific implementation of the air conditioner outdoor unit of the present application.

[0077] The outdoor unit of the air conditioner usually works in conjunction with the indoor unit of the air conditioner to achieve cooling or heating of the indoor environment.

[0078] Among them, the air conditioner outdoor unit is usually installed outdoors, and the air conditioner indoor unit is usually installed indoors. The air conditioner outdoor unit and the air conditioner indoor unit cooperate with each other and form a refrigerant circulation loop, so that the refrigerant circulates between the air conditioner indoor unit and the air conditioner outdoor unit through the refrigerant circulation loop, thereby cooling or heating the indoor environment.

[0079] like Figure 1 As shown, the air-conditioning outdoor unit provided in the present application includes at least a housing 100 , an outdoor heat exchanger 200 , an outdoor fan 300 , a compressor 600 , a gas-liquid separator 500 , an electrical box 400 and a four-way valve assembly 800 .

[0080] like Figure 1 , Figure 3 and Figure 4 As shown, the shell 100 is used to form the overall appearance of the air-conditioning outdoor unit. The shell 100 has a top and a bottom. The top of the shell 100 and the bottom of the shell 100 are opposite ends, and the direction from the top of the shell 100 to the bottom of the shell 100 is the height direction of the shell 100; the left side of the shell 100 and the right side of the shell 100 are opposite sides, and the direction from the left side of the shell 100 to the right side of the shell 100 is the length direction of the shell 100; the front side of the shell 100 and the rear side of the shell 100 are opposite sides, and the direction from the front side of the shell 100 to the rear side of the shell 100 is the thickness direction of the shell 100.

[0081] In practical applications, the housing 100 is usually disposed outdoors, wherein the rear side of the housing 100 is disposed toward a wall.

[0082] The housing 100 includes a bottom plate 120 , which is located at the bottom of the housing 100 , and the outdoor heat exchanger 200 , the compressor 600 , the gas-liquid separator 500 and the four-way valve assembly 800 are respectively placed on the bottom plate 120 .

[0083] The housing 100 includes a frame 110 , which is disposed around the housing 100 . The frame 110 is connected to and located on a bottom plate 120 . The frame 110 and the bottom plate 120 together define a space inside the housing 100 .

[0084] In some embodiments, the housing 100 further includes a foot 130 , which is disposed at the bottom of the base plate 120 to support the base plate 120 .

[0085] The outdoor heat exchanger 200 is used to exchange heat with the air passing therethrough, and the outdoor heat exchanger 200 is disposed inside the housing 100 .

[0086] In some embodiments, the outdoor heat exchanger 200 extends around the shell 100 to increase the contact area between the outdoor heat exchanger 200 and the air, thereby enhancing the heat exchange effect.

[0087] In some embodiments, the outdoor heat exchanger 200 extends from the front side of the shell 100, the left side of the shell 100, the rear side of the shell 100, and the right side of the shell 100 to the front side of the shell 100, and there is a gap between the two ends of the outdoor heat exchanger 200 extending around the shell 100, so that the outdoor heat exchanger 200 is C-shaped.

[0088] The refrigerant flows inside the outdoor heat exchanger 200 so that the outdoor heat exchanger 200 exchanges heat with the outdoor air.

[0089] It should be noted that the indoor unit of the air conditioner includes an indoor heat exchanger, and the refrigerant flows inside the indoor heat exchanger so that the indoor heat exchanger exchanges heat with the indoor air.

[0090] When the air conditioner cools or heats the indoor environment, the refrigerant flow direction is different. When cooling, the refrigerant first flows through the air conditioner outdoor heat exchanger. At this time, the outdoor heat exchanger 200 is the condenser and the indoor heat exchanger is the evaporator; when heating, the refrigerant first flows through the air conditioner indoor heat exchanger. At this time, the indoor heat exchanger is the condenser and the outdoor heat exchanger 200 is the evaporator.

[0091] It should also be noted that, in some embodiments, the frame 110 is a hollow structure, so that outdoor air can pass through the hollow portion of the frame 110 to exchange heat with the outdoor heat exchanger 200 .

[0092] In some embodiments, the outdoor heat exchanger 200 and the housing 100 together define an installation space, and the installation space is located inside the housing 100 .

[0093] like Figure 1 , Figure 3 and Figure 4 As shown, the outdoor fan 300 is used to drive air to contact the outdoor heat exchanger 200 ; the outdoor fan 300 is arranged on the top of the housing 100 .

[0094] In some embodiments, the outdoor fans 300 are designed to be two, and the two outdoor fans 300 are arranged side by side along the length direction of the shell 100 to increase the driving force on the air, so that more air contacts the outdoor heat exchanger 200, or the air contacts the outdoor heat exchanger 200 faster, thereby increasing the heat exchange efficiency of the outdoor heat exchanger 200.

[0095] like Figure 2 and Figure 5 As shown, the compressor 600 is disposed in the installation space and connected to the housing 100 .

[0096] The compressor 600, the outdoor heat exchanger 200 and the indoor heat exchanger form a refrigerant circulation loop through pipelines, so that the refrigerant circulates in the loop formed by the compressor 600, the outdoor heat exchanger 200 and the indoor heat exchanger.

[0097] The compressor 600 is used to compress low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure refrigerant gas, and provide power for the circulation of the refrigerant in the refrigerant circulation loop.

[0098] like Figure 2 and Figure 5 As shown, the gas-liquid separator 500 is disposed in the refrigerant circulation loop for separating the gaseous and liquid refrigerants; the gas-liquid separator 500 is located in the installation space and connected to the shell 100.

[0099] In some embodiments, one end of the gas-liquid separator 500 is connected to the compressor 600 , and the other end is connected to the outdoor heat exchanger 200 via a four-way valve assembly 800 .

[0100] In the gas-liquid separator 500 , the refrigerant flowing from the outdoor heat exchanger 200 to the compressor 600 via the four-way valve assembly 800 is separated into gas refrigerant and liquid refrigerant.

[0101] like Figure 2 and Figure 5 As shown, the four-way valve assembly 800 is arranged in the refrigerant circulation loop to change the flow direction of the refrigerant. Since the flow direction of the refrigerant is different in different states of cooling and heating of the air conditioner, if there is no four-way valve assembly 800, the air conditioner can only realize single cooling or heating, and cannot switch between cooling and heating.

[0102] The four-way valve assembly 800 includes a valve body having four ports, namely, an S port, a C port, a D port, and an E port.

[0103] The four-way valve assembly 800 also includes a connecting pipeline, which includes an S pipe 810, one end of the S pipe 810 is connected to the valve body, specifically to the S port of the valve body, and the other end is connected to the air inlet pipe of the gas-liquid separator 500;

[0104] The connecting pipeline further includes a C-tube 830 , one end of the C-tube 830 is connected to the valve body, specifically to the C port of the valve body, and the other end is connected to the outdoor heat exchanger 200 .

[0105] The connecting pipeline also includes an E-tube 840, one end of the E-tube 840 is connected to the valve body, specifically to the E port of the valve body, and the other end is connected to the indoor heat exchanger;

[0106] The connecting pipeline also includes a D-tube 820 , one end of which is connected to the valve body, specifically to the D port of the valve body, and the other end is connected to the exhaust port of the compressor 600 .

[0107] The S port, C port, D port and E port of the valve body of the four-way valve are connected to the S tube 810 , the C tube 830 , the E tube 840 and the D tube 820 respectively.

[0108] The refrigerant circulation loop is also provided with an expansion valve, which is used to convert the high-pressure liquid flowing through the indoor heat exchanger into a low-pressure liquid and transmit it to the outdoor heat exchanger 200.

[0109] It should be noted that the expansion valve can be arranged in the indoor unit of the air conditioner, and can also be arranged in the outdoor unit of the air conditioner.

[0110] It should also be noted that the expansion valve is usually an electronic expansion valve.

[0111] When the air conditioner is cooling, the refrigerant first passes through the compressor 600 to become a high-pressure gas, and then passes through the outdoor heat exchanger 200 (condenser) to condense and release heat to become a high-pressure liquid. The high-pressure liquid passes through the expansion valve and becomes a low-temperature and low-pressure liquid. It evaporates and absorbs heat through the indoor heat exchanger (evaporator) to become a low-temperature and low-pressure gas, and finally returns to the compressor 600.

[0112] When the air conditioner is heating, the refrigerant first passes through the compressor 600 to become a high-pressure gas, and then passes through the indoor heat exchanger (condenser) to condense and release heat to become a high-pressure liquid. The high-pressure liquid passes through the expansion valve to become a low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid passes through the outdoor heat exchanger 200 (evaporator) to evaporate and absorb heat to become a low-temperature and low-pressure gas, and finally returns to the compressor 600.

[0113] like Figure 1 As shown, the electrical box 400 is arranged in the installation space and connected to the housing 100; the electrical box 400 is provided with electrical components, which are connected to the outdoor fan 300 and the compressor 600 for controlling the operation of the outdoor fan 300 and the compressor 600.

[0114] like Figure 1 As shown, the air conditioner outdoor unit further includes a bracket 700 , which is connected to the housing 100 and is used to fix the electrical box 400 .

[0115] In some embodiments, the shell 100 is provided with a through portion, which is provided on the side wall of one side of the shell 100 , and both ends of the bracket 700 in the length direction are correspondingly connected to the two side edges of the through portion extending along the height direction of the shell 100 .

[0116] In another embodiment, a plurality of frames 110 are provided, and a certain distance is provided between two adjacent frames 110 close to or located at the front side of the shell 100 along the length direction of the shell 100 to form a passing portion.

[0117] Both ends of the bracket 700 in the length direction are correspondingly connected to two adjacent frames 110 for forming the passing portion.

[0118] like Figure 8 As shown, in some embodiments, bending portions 710 are provided at both ends of the bracket 700 in the length direction, and the bending portions 710 are connected to the frame 110 .

[0119] In other embodiments, the bending portion 710 is bent toward the inside of the installation space, and when the bending portion 710 is connected to the frame 110, the bracket 700 body protrudes in a direction away from the inside of the installation space.

[0120] It should be noted that protruding the bracket 700 body in a direction away from the interior of the installation space can reduce the installation space occupied by the bracket 700 to a certain extent.

[0121] like Figure 6 As shown, the air conditioner outdoor unit also includes a fixing component 900, which is used to constrain the connecting pipeline to prevent the connecting pipeline from breaking during transportation and causing refrigerant leakage.

[0122] In some embodiments, the fixation assembly 900 is used to constrain the C-tube 830 .

[0123] like Figure 9-11 As shown, the fixing assembly 900 includes a fixing member 940 , and the fixing member 940 is connected to the bracket 700 .

[0124] In some embodiments, the fixing member 940 is located on a side of the bracket 700 facing the mounting member.

[0125] like Figure 8 As shown, in some embodiments, a first rib 720 is provided on a side of the bracket 700 facing the fixing member 940 to increase the strength of the bracket 700 .

[0126] In other embodiments, the first rib 720 is formed by a protrusion on the surface of the bracket 700 toward the side where the bracket 700 is connected to the fixing member 940 , and a first recess corresponding to the first rib 720 is provided on the side of the bracket 700 away from the fixing member 940 .

[0127] In some embodiments, a second rib 944 is also provided on the side of the fixing member 940 facing away from the bracket 700 to increase the strength of the fixing member 940 .

[0128] In other embodiments, the second convex rib 944 is formed by a surface of the fixing member 940 protruding toward a side away from the bracket 700 , and a second recess 945 corresponding to the second convex rib 944 is provided on a side of the fixing member 940 facing the bracket 700 .

[0129] In some embodiments, the second recess 945 is matched with the first convex rib 720 , and when the fixing member 940 is connected to the bracket 700 , the first convex rib 720 is disposed in the second recess 945 .

[0130] The first rib 720 disposed in the second recess 945 can also locate the connection position between the fixing member 940 and the bracket 700 , and can also increase the overall strength after the bracket 700 and the fixing member 940 are connected, which is more conducive to the stability of the four-way valve assembly 800 .

[0131] In some embodiments, the fixing member 940 is U-shaped and includes an open end and a closed end, wherein the open end is connected to the bracket 700 and the closed end is connected to the second mounting member 930 .

[0132] The third mounting portion 942 is disposed at the closed end of the fixing member 940 .

[0133] In other embodiments, a reinforcement portion 941 is provided at the open end of the fixing member 940 , and the reinforcement portion 941 is used to increase the contact area between the fixing member 940 and the bracket 700 .

[0134] It should be noted that the bracket 700 and the fixing member 940 can be connected by welding, screws and nuts, etc.

[0135] like Fig. 9 , Fig.10 and Fig.12 As shown, the fixing assembly 900 further includes a mounting member, which is detachably connected to the fixing member 940 , and the mounting member is connected to the C-tube 830 to constrain the C-tube 830 .
