Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning outdoor unit and an air conditioner. Background Art

[0002] Air conditioners are an indispensable electrical appliance in people's daily life, with a variety of structural forms. With the continuous improvement of industrial design level and the application of new technology, new materials and new shapes in air conditioners, various air conditioners have been developed.

[0003] Taking a heat pump air conditioner capable of producing hot water as an example, in the prior art, a water module is often arranged near a compressor assembly inside a heat pump air conditioner outdoor unit, so as to provide air conditioning refrigeration for users by using refrigerant, and to produce hot water through the water module by using the high-temperature refrigerant formed after air conditioning refrigeration. However, in the existing heat pump air conditioner outdoor unit, the various components of the water module and the various components of the compressor assembly are often arranged in a rather messy manner, which is not convenient for disassembly and maintenance of the water module or the compressor assembly, and is not conducive to improving the space utilization rate inside the outdoor unit, making it difficult to further reduce the overall volume of the outdoor unit. Summary of the invention

[0004] In view of this, the present invention aims to propose an air-conditioning outdoor unit and an air conditioner to solve the problem that the water module and compressor assembly inside the existing heat pump air-conditioning outdoor unit are arranged in a relatively messy manner, are not convenient for disassembly and maintenance, and are not conducive to improving the space utilization inside the outdoor unit.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] An air-conditioning outdoor unit comprises a fan, a compressor assembly, and a water module assembly, wherein a wind-blocking vertical plate is arranged between the fan and the compressor assembly, the water module assembly is connected to a water module assembly plate, and at least a portion of the plate structure of the water module assembly plate is arranged between the compressor assembly and the water module assembly. The inner cavity of the outdoor unit is divided into a first chamber, a second chamber, and a third chamber, the fan is arranged in the first chamber, the compressor assembly is arranged in the second chamber, and the water module assembly is arranged in the third chamber, the lower end of the wind-blocking vertical plate and the lower end of the water module assembly plate are connected to the chassis of the outdoor unit, and the top of the second chamber is connected to the top of the third chamber. Therefore, the present application divides the inner cavity of the outdoor unit into three independent chambers by setting up wind-blocking vertical plates and water module assembly plates, so that the fan, compressor assembly and water module assembly can be installed in the corresponding chambers respectively, which reduces the clutter of the various components inside the outdoor unit to a certain extent. On the one hand, the fan, compressor assembly and water module assembly all have independent assembly space and operation space, and there is no spatial obstruction between them. During the disassembly and maintenance process, it is only necessary to operate the components in a specific chamber without changing the setting of the components in other chambers, which facilitates the disassembly and maintenance of components such as the water module and compressor assembly. On the other hand, it is beneficial for the compressor assembly and the water module assembly to be arranged in the corresponding chamber in a more concentrated manner, which is beneficial to improve the space utilization inside the outdoor unit, and accordingly, it is also beneficial to reduce the overall volume of the outdoor unit. In addition, by setting up the water module assembly plate, the compressor assembly and the water module assembly can be separated to a certain extent. At the same time, since the compressor assembly is centrally arranged in the second chamber, when a refrigerant leaks from the compressor assembly, the leaked refrigerant tends to be concentrated in the middle and lower part of the second chamber under the action of gravity. The water module assembly plate can effectively block the refrigerant, preventing the refrigerant from flowing directly to the water module assembly more easily, thereby reducing the safety hazards at the water module assembly.

[0007] Furthermore, the compressor assembly includes a compressor, a first liquid storage tank, a second liquid storage tank, and a four-way valve. The compressor is connected to the chassis of the outdoor unit. The first liquid storage tank, the second liquid storage tank, and the four-way valve are all arranged above the compressor. The first liquid storage tank is connected to the wind shielding plate, and the second liquid storage tank is connected to the water module assembly plate. In the projection direction from top to bottom, the projection of the first liquid storage tank, the projection of the second liquid storage tank, and the projection of the four-way valve interface are all located within the projection area of ​​the second chamber. Therefore, compared with the traditional outdoor unit in which the liquid storage tank is fixed on the chassis, arranging the first liquid storage tank and the second liquid storage tank above the compressor can make full use of the space in the vertical direction of the second chamber, which is conducive to fully improving the space utilization rate; in addition, the compressor is arranged in the second chamber, and the projection of the first liquid storage tank, the projection of the second liquid storage tank, and the projection of the four-way valve interface are all located in the projection area of ​​the second chamber, so that all components of the compressor assembly and most of the refrigerant pipelines are located in the second chamber (or the projection of the second chamber). If a refrigerant leaks in the compressor assembly, the refrigerant can gather in the middle and lower part of the second chamber under the action of its own weight.

[0008] Furthermore, the length direction of the four-way valve is parallel to the horizontal plane, and the four-way valve is arranged between the first liquid storage tank and the second liquid storage tank. In the vertical direction, the top of the first liquid storage tank and the second liquid storage tank, whichever has the smallest top height, is higher than the height of the four-way valve, and the bottom of the first liquid storage tank and the second liquid storage tank, whichever has the largest bottom height, is lower than the height of the four-way valve. That is, the four-way valve is not higher than the top of any liquid storage tank, nor lower than the bottom of any liquid storage tank. Therefore, the distance difference between the components of the compressor assembly will not be too large, which is convenient for optimizing the layout of the refrigerant pipeline, avoiding the situation where individual pipelines are too long, and can effectively reduce the risk of transportation damage to related pipelines and components.

[0009] Furthermore, the line connecting the axis of the first liquid storage tank and the axis of the second liquid storage tank is denoted as M. In the projection direction from top to bottom, the angle between M and the straight line in the front-back direction is 35°-55°. Thus, in the present application, one of the two liquid storage tanks is relatively forward and the other is relatively backward, which fully utilizes the space of the second chamber in the front-back direction, and is also beneficial to reduce the length of the second chamber in the left-right direction to a certain extent. At the same time, a certain space can be reserved for the setting of the four-way valve, which can effectively improve the compactness of the compressor assembly layout, improve the space utilization rate, and also help to reduce the space size of the second chamber and the volume of the whole machine.

[0010] Furthermore, the straight line where the length direction of the four-way valve is located is recorded as N, and in the projection direction from top to bottom, M intersects with N, and the angle between M and N is 75°-90°. Therefore, in the middle and upper part of the second chamber, M and N intersect to form a shape similar to "X", which not only fully utilizes the space of the second chamber in the vertical direction and the front-to-back direction, but also minimizes the interference of the length of the four-way valve itself on the size of the second chamber in the left-right direction, which can further improve the compactness of the compressor assembly layout and improve the space utilization rate.

[0011] Furthermore, in the projection direction from top to bottom, the ratio of the minimum distance of the axis center distance N of the first liquid storage tank to the minimum distance of the axis center distance N of the second liquid storage tank is 0.33-3.00. Therefore, the setting position of the four-way valve between the first liquid storage tank and the second liquid storage tank has a certain adjustable space, which reserves a certain adjustable margin for the actual design and actual assembly of the air-conditioning related components, and at the same time, it will not cause the components to interfere with each other due to being too close to each other.

[0012] Furthermore, the water module assembly plate includes a first plate body and a second plate body, the first plate body is connected to the second plate body, at least the first plate body is arranged between the compressor assembly and the water module assembly, a clearance plate is arranged on the side of the first plate body away from the second plate body, the distance between the clearance plate and the wind-blocking vertical plate is greater than the distance between the first plate body and the wind-blocking vertical plate, and the upper part of the clearance plate is connected to the second liquid storage tank. Thus, by arranging the clearance plate, the front plate structure of the water module assembly plate forms a depression toward the third chamber, and a part of the front space of the third chamber is given to the second chamber. On the premise of meeting the assembly of the electric heater, water pump and other components in the front of the third chamber, the space size of the second chamber is increased, providing more space margin for the arrangement of the compressor assembly, which is conducive to optimizing the space allocation of each chamber and improving the space utilization rate inside the outdoor unit.

[0013] Furthermore, a mounting plate is provided on the upper part of the said clearance plate, and the second liquid storage tank is connected to the mounting plate. Since the height of the water module assembly plate is less than the height of the windproof vertical plate, by further providing the mounting plate, the installation height between the second liquid storage tanks is made as close as possible to the first liquid storage tank, especially ensuring that the bottom ends of the first liquid storage tank and the second liquid storage tank are both higher than the top end of the compressor, so that the height space of the second chamber is fully utilized, and at the same time, the second liquid storage tank is prevented from interfering with the compressor due to the lower height of the water module assembly plate (lower installation position).

[0014] Furthermore, the outdoor unit includes an external discharge piece, the air inlet side of the external discharge piece is connected to the second chamber, the air outlet side of the external discharge piece can be connected to the external environment, and the water module assembly plate is provided with a refrigerant sensor. Thus, by providing an external discharge piece and using the refrigerant sensor to detect the refrigerant concentration, when the refrigerant concentration reaches a certain threshold, the external discharge piece is opened to extract the refrigerant leaked from the compressor assembly and discharge it into the external environment, so as to avoid safety risks to the water module assembly, the electric control box and other components due to the excessive refrigerant concentration inside the outdoor unit. At the same time, due to the separation effect of the wind-proof plate and the water module assembly plate, the refrigerant leaked from the compressor assembly will be concentrated in the middle and lower part of the second chamber, so as to prevent the refrigerant from flowing directly to the water module assembly more easily, thereby reducing the safety hazards at the water module assembly.

[0015] An air conditioner comprises an indoor unit and an outdoor unit of the air conditioner, wherein the indoor unit is connected to the outdoor unit.

[0016] Compared with the prior art, the air conditioner outdoor unit and the air conditioner described in the present invention have the following advantages:

[0017] The air-conditioning outdoor unit and air-conditioning described in the present invention divide the inner cavity of the outdoor unit into three independent chambers by arranging a wind-blocking vertical plate and a water module assembly plate, so that the fan, compressor assembly and water module assembly can be installed in the corresponding chambers respectively, which reduces the clutter of the various components inside the outdoor unit to a certain extent. On the one hand, the fan, compressor assembly and water module assembly all have independent assembly space and operation space, and there is no spatial obstruction to each other. During the disassembly and maintenance process, it is only necessary to operate the components in a specific chamber without changing the arrangement of the components in other chambers, which facilitates the disassembly and maintenance of the water module, compressor assembly and other components. On the other hand, it is beneficial for the compressor assembly and the water module assembly to be arranged in the corresponding chamber in a more concentrated manner, which is beneficial to improve the space utilization inside the outdoor unit, and accordingly, it is also beneficial to reduce the overall volume of the outdoor unit.

[0018] In addition, by setting up the water module assembly plate, the compressor assembly and the water module assembly can be separated to a certain extent. At the same time, since the compressor assembly is centrally arranged in the second chamber, when a refrigerant leaks from the compressor assembly, the leaked refrigerant tends to be concentrated in the middle and lower part of the second chamber under the action of gravity. The water module assembly plate can effectively block the refrigerant, preventing the refrigerant from flowing directly to the water module assembly more easily, thereby reducing the safety hazards at the water module assembly.

DETAILED DESCRIPTION

[0038] The inventive concepts of the present disclosure will be described below using terms commonly used by those skilled in the art to convey the essence of their work to other persons skilled in the art. However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.

[0039] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The directional terms used in this application are based on the directional position of the air conditioner outdoor unit in a conventional assembly and conventional placement state. Figure 1 , 2 The coordinates in .

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0041] Example 1

[0042] In the existing heat pump air-conditioning outdoor unit, the various components of the water module and the various components of the compressor assembly are often arranged in a rather messy manner. Firstly, it is not convenient to disassemble and maintain the water module or the compressor assembly. Secondly, it is not conducive to improving the space utilization inside the outdoor unit, making it difficult to further reduce the overall volume of the outdoor unit.

[0043] In order to solve the problem that the water module and compressor assembly in the existing heat pump air conditioner outdoor unit are arranged in a messy manner, which is not convenient for disassembly and maintenance, and is not conducive to improving the space utilization rate inside the outdoor unit, this embodiment proposes an air conditioner outdoor unit, as shown in the attached Figure 1-4 As shown, the outdoor unit includes a fan 1, a compressor assembly 2, and a water module assembly 3. A wind-blocking vertical plate 4 is arranged between the fan 1 and the compressor assembly 2. The water module assembly 3 is connected to a water module assembly plate 5. At least part of the plate structure of the water module assembly plate 5 is arranged between the compressor assembly 2 and the water module assembly 3.

[0044] By arranging a wind-blocking vertical plate 4 and a water module assembly plate 5 inside the outdoor unit, the inner cavity of the outdoor unit is divided into a first chamber 7, a second chamber 8, and a third chamber 9 in sequence, the fan 1 is arranged in the first chamber 7, the compressor assembly 2 is arranged in the second chamber 8, and the water module assembly 3 is arranged in the third chamber 9. The first chamber 7, the second chamber 8, and the third chamber 9 can be independent chambers isolated from each other, or chambers with a certain connection relationship. Since a refrigerant pipeline needs to be arranged between the compressor assembly 2 and the water module assembly 3 so that the refrigerant can exchange heat with water in the water module assembly 3, in the present application, it is preferred to connect the top of the second chamber 8 with the top of the third chamber 9, so as to facilitate the arrangement of the refrigerant pipeline between the compressor assembly 2 and the water module assembly 3, and avoid spatial interference between the water module assembly plate 5 and the rigid refrigerant pipeline. Specifically, the lower end of the wind-blocking plate 4 and the lower end of the water module assembly plate 5 are connected to the chassis 11 of the outdoor unit, and in the vertical direction, the height of the water module assembly plate 5 is smaller than the height of the wind-blocking plate 4. As the density of the refrigerant is often greater than the density of the air, the leaked refrigerant tends to be concentrated in the middle and lower part of the second chamber 8. The water module assembly plate 5 isolates the middle and lower part of the second chamber 8 and the middle and lower part of the third chamber 9, thereby preventing the refrigerant from flowing into the third chamber 9 and causing safety hazards.

[0045] Therefore, the present application divides the inner cavity of the outdoor unit into three independent chambers by setting up wind-blocking vertical plates 4 and water module assembly plates 5, so that the fan 1, compressor assembly 2, and water module assembly 3 can be installed in corresponding chambers respectively, which reduces the clutter of various components inside the outdoor unit to a certain extent. On the one hand, the fan 1, compressor assembly 2, and water module assembly 3 all have independent assembly space and operation space, and there is no spatial obstruction to each other. During the disassembly and maintenance process, it is only necessary to operate the components in a specific chamber without changing the setting of the components in other chambers, which facilitates the disassembly and maintenance of components such as the water module and compressor assembly. On the other hand, it is beneficial for the compressor assembly 2 and the water module assembly 3 to be arranged in the corresponding chamber in a more concentrated manner, which is beneficial to improve the space utilization inside the outdoor unit, and accordingly, it is also beneficial to reduce the overall volume of the outdoor unit.

[0046] In addition, by setting the water module assembly plate 5, the compressor assembly 2 and the water module assembly 3 can be separated to a certain extent. At the same time, since the compressor assembly 2 is centrally arranged in the second chamber 8, when a refrigerant leaks from the compressor assembly 2, the leaked refrigerant will often be concentrated in the middle and lower parts of the second chamber 8 under the action of gravity. The water module assembly plate 5 can effectively block the refrigerant, preventing the refrigerant from flowing directly to the water module assembly 3 more easily, thereby reducing the safety hazards at the water module assembly 3.

[0047] Regarding the arrangement of the compressor assembly 2 in the second chamber 8, the compressor assembly 2 includes a compressor 21, a first liquid storage tank 22, a second liquid storage tank 23, and a four-way valve 24. The compressor 21 is connected to the chassis 11 of the outdoor unit. The first liquid storage tank 22, the second liquid storage tank 23, and the four-way valve 24 are all arranged above the compressor 21. The first liquid storage tank 22 is connected to the wind shielding plate 4, and the second liquid storage tank 23 is connected to the water module assembly plate 5. In the projection direction of the outdoor unit from top to bottom, the projection of the first liquid storage tank 22, the projection of the second liquid storage tank 23, and the projection of the interface of the four-way valve 24 are all located within the projection area of ​​the second chamber 8. Therefore, compared with the traditional outdoor unit in which the liquid storage tank is fixed on the chassis, the first liquid storage tank 22 and the second liquid storage tank 23 are arranged above the compressor 21, which can make full use of the space of the second chamber 8 in the vertical direction, which is conducive to fully improving the space utilization rate; in addition, the compressor 21 is arranged in the second chamber 8, and the projection of the first liquid storage tank 22, the projection of the second liquid storage tank 23, and the projection of the four-way valve 24 interface are all located in the projection area of ​​the second chamber 8, so that all components of the compressor assembly 2 and most of the refrigerant pipelines are located in the second chamber 8 (or the projection of the second chamber 8). If a refrigerant leak occurs in the compressor assembly 2, the refrigerant can gather in the middle and lower part of the second chamber 8 under the action of its own weight.

[0048] The length direction of the four-way valve 24 is parallel to the horizontal plane, and is arranged between the first liquid storage tank 22 and the second liquid storage tank 23. In the vertical direction, the top of the first liquid storage tank 22 and the second liquid storage tank 23, whichever has the smallest top height, is higher than the height of the four-way valve 24, and the bottom of the first liquid storage tank 22 and the second liquid storage tank 23, whichever has the largest bottom height, is lower than the height of the four-way valve 24; that is, the four-way valve 24 is not higher than the top of any liquid storage tank, nor lower than the bottom of any liquid storage tank. Thus, the distance difference between the components of the compressor assembly 2 will not be too large, which is convenient for optimizing the layout of the refrigerant pipeline, avoiding the occurrence of excessive length of individual pipelines, and can effectively reduce the risk of transportation damage to related pipelines and components. Preferably, the first liquid storage tank 22 and the second liquid storage tank 23 are at the same or similar heights, and the four-way valve 24 is located between the first liquid storage tank 22 and the second liquid storage tank 23 in the horizontal direction and the height direction.

[0049] For the liquid storage tank, it is often cylindrical and has a corresponding central axis. The line between the axis of the first liquid storage tank 22 and the axis of the second liquid storage tank 23 is denoted as M. In the projection direction from top to bottom, the angle between M and the straight line in the front-to-back direction is 35°-55°. Therefore, in the present application, the first liquid storage tank 22 is relatively close to the first chamber 7, the second liquid storage tank 23 is relatively close to the third chamber 9, and one of the two liquid storage tanks is relatively forward and the other is relatively backward, which makes full use of the space of the second chamber 8 in the front-to-back direction. To a certain extent, it is also beneficial to reduce the length of the second chamber 8 in the left-right direction. At the same time, it can also reserve a certain space for the setting of the four-way valve 24, which can effectively improve the compactness of the compressor assembly 2, improve the space utilization rate, and also help to reduce the space size of the second chamber 8 and the volume of the whole machine.

[0050] It should be noted that the term "angle" in this application refers to the minimum angle between two lines in a mathematical sense, and the angle range is 0°-90°.

[0051] The straight line of the length direction of the four-way valve 24 is recorded as N. In the projection direction from top to bottom, M intersects with N, and the angle between M and N is 75°-90°. Preferably, in the projection direction from top to bottom, M intersects with the four-way valve 24 (length direction), and the angle formed by the intersection is the angle between M and N.

[0052] Specifically, from the perspective of three-dimensional space, since the length direction of the four-way valve 24 is parallel to the horizontal plane, and the liquid storage tanks are often arranged in the vertical direction, the central axis of the first liquid storage tank 22 and the central axis of the second liquid storage tank 23 are coplanar, recorded as a virtual plane, and the four-way valve 24 can pass through the virtual plane. The angle between the four-way valve 24 (length direction) and the virtual plane is the angle between M and N.

[0053] Thus, in the upper and middle part of the second chamber 8, M and N intersect to form a shape approximating to an "X", which not only fully utilizes the space of the second chamber 8 in the vertical direction and the front-to-back direction, but also minimizes the interference of the length of the four-way valve 24 itself on the size of the second chamber 8 in the left-right direction, thereby further improving the compactness of the layout of the compressor assembly 2 and improving space utilization.

[0054] Preferably, in the projection direction from top to bottom, the ratio of the minimum distance of the axis center distance N of the first liquid storage tank 22 to the minimum distance of the axis center distance N of the second liquid storage tank 23 is 0.33-3.00. Therefore, between the first liquid storage tank 22 and the second liquid storage tank 23, the setting position of the four-way valve 24 has a certain adjustable space, and a certain adjustable margin is reserved for the actual design and actual assembly of the air-conditioning related components. At the same time, the situation of component interference caused by the components being too close to each other will not occur.

[0055] As for the assembly of the water module assembly 3, the water module assembly 3 includes an expansion tank 31, an electric heater 32, a plate heat exchanger 33, and a water pump 34. The water module assembly plate 5 includes a first plate body 51 and a second plate body 52. ​​The first plate body 51 is connected to the second plate body 52 to form a plate body structure approximately in an L shape. At least the first plate body 51 is arranged between the compressor assembly 2 and the water module assembly 3. The expansion tank 31 is located at the connection between the first plate body 51 and the second plate body 52. ​​The expansion tank 31 can be connected to the first plate body 51, or to the second plate body 52, or to the first plate body 51 and the second plate body 52 at the same time; the electric heater 32 is connected to the first plate body 51 and is arranged in front of the expansion tank 31; the plate heat exchanger 33 is connected to the second plate body 52 and is arranged on the right side of the expansion tank 31. Specifically, due to the plate heat exchanger 33 is heavy and inconvenient to punch holes, a support seat 53 is set at the bottom of the plate heat exchanger 33, the support seat 53 is connected to the chassis 11, and the second plate body 52 is provided with a limit plate 54, the limit plate 54 is located above the support seat 53 and fits with the outer wall surface of the plate heat exchanger 33, and makes the plate heat exchanger 33 abut against the second plate body 52, which is used to limit and fix the plate heat exchanger 33; the water pump 34 is connected with the electric heater 32 and the plate heat exchanger 33 through pipelines respectively.

[0056] Since the front part of the entire water module assembly 3 is composed of components such as the electric heater 32 and the water pump 34, which are relatively small in size, in order to further reasonably allocate the space of each chamber inside the outdoor unit, a clearance plate 511 is provided on the side of the first plate body 51 away from the second plate body 52, and the distance between the clearance plate 511 and the wind-blocking upright plate 4 is greater than the distance between the first plate body 51 and the wind-blocking upright plate 4, and the upper part of the clearance plate 511 is connected to the second liquid storage tank 23, so that by providing the clearance plate 511, the front plate structure of the water module assembly plate 5 is recessed toward the third chamber 9, and a part of the front space of the third chamber 9 is given to the second chamber 8. On the premise of meeting the assembly of components such as the electric heater 32 and the water pump 34 in the front of the third chamber 9, the space size of the second chamber 8 is increased, providing more space margin for the arrangement of the compressor assembly 2, which is beneficial to optimizing the space allocation of each chamber and improving the space utilization rate inside the outdoor unit.

[0057] The upper part of the said clearance plate 511 is provided with a mounting plate 6, and the second liquid storage tank 23 is connected with the mounting plate 6. Since the height of the water module assembly plate 5 is less than the height of the windproof vertical plate 4, by further providing the mounting plate 6, the installation height between the second liquid storage tanks 23 is made as close as possible to the first liquid storage tank 22, especially ensuring that the bottom ends of the first liquid storage tank 22 and the second liquid storage tank 23 are both higher than the top end of the compressor 21, so that the height space of the second chamber 8 is fully utilized, and at the same time, the second liquid storage tank 23 is prevented from interfering with the compressor 21 due to the lower height of the water module assembly plate 5 (lower installation position).

[0058] In addition, as the shell structure of the outdoor unit, the outdoor unit is provided with a front panel 13, a back panel 15, and a side panel 12. The front panel 13 is located in the front side of the compressor assembly 2 and the water module assembly 3, the back panel 15 is located in the rear side of the compressor assembly 2 and the water module assembly 3, and the side panel 12 is located on the side of the water module assembly 3 away from the compressor assembly 2, so that the corresponding chamber structure is enclosed by the corresponding shell structure, wind shielding vertical plate 4, water module assembly plate 5 and other components.

[0059] Example 2

[0060] Based on Example 1, this example further introduces the possible refrigerant leakage at the compressor assembly and the corresponding structural improvements.

[0061] In the outdoor unit of a conventional heat pump air conditioner, the water module is often placed adjacent to the compressor assembly. If a refrigerant leaks from the compressor assembly, the refrigerant will flow directly to the water module. Since an electric heating device is often installed in the water module, as the concentration of the refrigerant in the water module increases, there are often safety hazards such as explosion and combustion. In fact, as the refrigerant continues to leak, part of the refrigerant will spread to the electric control box of the outdoor unit. Since a large number of electrical components are concentrated in the electric control box, the risk of combustion and explosion inside the air conditioner outdoor unit will be further increased on the basis of the safety hazard at the water module.

[0062] As attached Figure 5-6 As shown, the outdoor unit includes an external discharge member 14, the air inlet side of the external discharge member 14 is connected to the second chamber 8, the air outlet side of the external discharge member 14 can be connected to the external environment, and the water module assembly plate 5 is provided with a refrigerant sensor 61, which is at least used to detect the refrigerant concentration in the second chamber 8. Thus, by providing the external discharge member 14 and using the refrigerant sensor 61 to detect the refrigerant concentration, when the refrigerant concentration reaches a certain threshold, the external discharge member 14 is opened to extract the refrigerant leaked from the compressor assembly 2 and discharge it into the external environment, so as to avoid the water module assembly 3, the electric control box 10 and other components being exposed to safety risks due to the excessive refrigerant concentration inside the outdoor unit. At the same time, due to the separation effect of the wind-proof vertical plate 4 and the water module assembly plate 5, the refrigerant leaked from the compressor assembly 2 will be concentrated in the middle and lower part of the second chamber 8, so as to prevent the refrigerant from flowing directly to the water module assembly 3 relatively easily, thereby reducing the safety hazard at the water module assembly 3.

[0063] A refrigerant sensor 61 is arranged on the upper part of the water module assembly plate 5, and specifically, the refrigerant sensor 61 is connected to the clearance plate 511. Due to the separation of the windproof plate 4 and the water module assembly plate 5, the leaked refrigerant tends to be concentrated in the middle and lower part of the second chamber 8. By arranging the refrigerant sensor 61 on the upper part of the water module assembly plate 5, when the refrigerant in the second chamber 8 reaches a certain amount and overflows from the second chamber 8 to the third chamber 9, the refrigerant sensor 61 can detect in time that the refrigerant may flow to the water module assembly 3, so that the air conditioner can open the external exhaust part 14 in time; at the same time, it can also avoid the improper position setting of the refrigerant sensor 61, which causes the external exhaust part 14 to be opened too frequently.

[0064] The outer row member 14 in the present application can be regarded as an outer row device alone, or it can be combined with other components to form an outer row device. Specifically, the present application proposes two configuration forms of the outer row member 14 for reference.

[0065] Form 1

[0066] As attached Figure 5 As shown, the external discharge member 14 is a fan structure, and the refrigerant can be discharged directly to the external environment through the fan.

[0067] Regarding the assembly of the external discharge member 14, the outdoor unit includes a front panel 13, the front panel 13 is provided with an installation opening, the installation opening is directly connected to at least the second chamber 8, and the external discharge member 14 is arranged in the installation opening and connected to the front panel 13. Therefore, since the front of the air-conditioning outdoor unit is often relatively open, when the external discharge member 14 discharges the refrigerant, the external discharge member 14 can discharge the refrigerant directly toward the front of the outdoor unit, which is convenient for the timely diffusion of the refrigerant and avoids the stagnation of the refrigerant at the outdoor unit. At this time, the external discharge member 14 can be regarded as an external discharge device alone.

[0068] It should be noted that, for different designs of outdoor units, the front panel 13 can be a whole front panel of a conventional outdoor unit, or it can be composed of multiple panels. For example, the front panel 13 shown in the drawings of the present application can be regarded as one of the multiple panels, which can be called a small panel, mainly serving as the front panel structure at the second chamber 8 and the third chamber 9. Correspondingly, another large panel is also provided at the first chamber 7. The small panel and the large panel can together constitute the front panel structure of the entire outdoor unit.

[0069] In the vertical direction, the lower edge of the installation opening is higher than the upper end of the water module assembly plate 5, so that the external discharge member 14 can not only communicate with the second chamber 8, but also communicate with the upper part of the third chamber 9 and the connecting space of the upper part of the second chamber 8, and even communicate with the third chamber 9, so that the external discharge member 14 can simultaneously discharge the gas in the second chamber 8 and the third chamber 9, reduce the refrigerant concentration at the water module assembly 3 and other parts of the air conditioner (such as the electric control box 10 at the top of the outdoor unit), and avoid the occurrence of safety accidents. In addition, considering the spatial interference, the upper edge of the installation opening is lower than the bottom wall of the electric control box 10 to avoid the electric control box 10 from hindering the refrigerant discharge process of the external discharge member 14, and ensure the normal operation of the external discharge member 14.

[0070] Form 2

[0071] As attached Figure 6 As shown, the external discharge member 14 is a wind valve structure, and the external discharge member 14 is arranged on the wind-blocking vertical plate 4. The external discharge member 14 and the fan 1 work together to form an external discharge device. In the process of discharging the refrigerant, by opening the wind valve structure, the second chamber 8 is connected with the first chamber 7 through the valve port of the wind valve structure. With the rotation of the fan 1 in the first chamber 7, the leaked refrigerant can be drawn into the first chamber 7 and discharged into the external environment.

[0072] For the assembly of the outer row member 14, the wind-blocking vertical plate 4 is provided with a connecting port (not shown), and the outer row member 14 is connected to the connecting port. Accordingly, the opening size of the connecting port is adapted to the outer row member 14 as much as possible to ensure the normal and secure assembly of the outer row member 14. For the outer row member 14 (i.e., the air valve structure), it can be a damper structure, and the damper is driven by a motor to move to realize the opening and closing of the outer row member 14. It can also be in the form of a blind or a roller curtain, which is provided at the connecting port to block or open the connecting port. At this time, the connecting port can be regarded as the valve port of the outer row member 14. In view of the specific structure and opening and closing method of the air valve form, reference can be made to the prior art, and no further description is given here.

[0073] The lower edge of the valve port of the external discharge member 14 is lower than the upper end of the water module assembly plate 5, and the upper edge of the valve port of the external discharge member 14 is higher than the upper end of the water module assembly plate 5. Therefore, after the external discharge member 14 is opened, on the one hand, the leaked refrigerant in the second chamber 8 can be discharged, and on the other hand, the valve port of the external discharge member 14 can also discharge the gas in the connecting space between the upper part of the third chamber 9 and the upper part of the second chamber 8, and even to a certain extent, the gas in the third chamber 9 can be discharged, thereby reducing the refrigerant concentration at the water module assembly 3 and other parts of the air conditioner (such as the electric control box 10 at the top of the outdoor unit), and avoiding the occurrence of safety accidents.

[0074] The outdoor unit includes an electric control box 10, and an assembly port is provided at the top of the wind-blocking plate 4, and the electric control box 10 is arranged in the assembly port and connected to the wind-blocking plate 4. Therefore, on the one hand, the wind-blocking plate 4 is used as a support assembly point of the electric control box 10, which is conducive to improving the assembly reliability of the electric control box 10 inside the outdoor unit. On the other hand, the electric control box 10 is located at the upper part of the outdoor unit, as far away as possible from the leaked refrigerant collected in the middle and lower part of the second chamber 8. At the same time, through the action of the refrigerant sensor 61 and the external discharge member 14, when the refrigerant overflows the upper part of the water module assembly plate 5, it can be discharged from the inside of the outdoor unit in time, so that the leaked refrigerant will not easily flow to the electric control box 10, and will not be enriched in the electric control box 10, which is conducive to eliminating the safety hazard of explosion and combustion of the electric control box 10 caused by refrigerant leakage. In this embodiment, the inner cavity of the electric control box 10 is preferably not connected to the second chamber 8 and the third chamber 9, so as to avoid the leaked refrigerant from entering the electric control box 10 as much as possible.

[0075] The electric control box 10 often needs to dissipate heat from the electric control components inside it. This embodiment further improves the corresponding heat dissipation structure. Figure 7-8As shown, the electric control box 10 includes a box body 101, a box cover 102, an air inlet pipe 103, and an air outlet pipe 104. A receiving cavity is formed between the box body 101 and the box cover 102 for receiving and installing the electric control components. The box body 101 is provided with a first opening 1011 and a second opening 1012. The air inlet end of the air inlet pipe 103 is communicated with the external environment, and the air outlet end of the air inlet pipe 103 is communicated with the first opening 1011 for conveying fresh air into the receiving cavity. The air inlet end of the air outlet pipe 104 is communicated with the second opening 1012, and the air outlet end of the air outlet pipe 104 is communicated with the first chamber 7, so that a negative pressure is formed as the fan 1 in the first chamber 7 is operated, so that a part of the air in the external environment is blown along the surrounding Figure 7 The direction of the arrow in the figure flows through the inside of the electric control box 10. On the one hand, the air flowing through the inside of the electric control box 10 will exchange heat with the electric control components, take away part of the heat, and improve the heat dissipation performance of the electric control box. On the other hand, even if refrigerant enters the inside of the electric control box 10, as the fresh air from the outside continuously flows through the inside of the electric control box 10, the concentration of the refrigerant that may exist inside the electric control box will be reduced, avoiding electric ignition, combustion or explosion, and improving the safety performance of the use of the electric control box. At the same time, the original fan 1 is used to introduce and discharge fresh air inside the electric control box, and there is no need to set up an additional air inlet or air outlet fan for the electric control box 10, which reduces the setting of air conditioning components. As for the air inlet duct 103, the air outlet duct 104, and the box cover 102, they can all be connected to the box body 101 through fasteners.

[0076] The outdoor unit includes a back plate 15, and the back plate 15 is provided with an air inlet window 151. The air inlet end of the air inlet pipe 103 is connected to the air inlet window 151, and is communicated with the outdoor environment through the air inlet window 151. In addition, in the vertical direction, the height of the air inlet window 151 is lower than the height of the first opening 1011. Correspondingly, in the direction from the first opening 1011 to the air inlet window 151, the air inlet pipe 103 extends downwardly at an angle; similarly, in the vertical direction, the height of the second opening 1012 is higher than the air outlet end of the air outlet pipe 104. This can prevent external rainwater or condensed water from entering the electric control box, ensuring the safe operation of the electric control components inside the electric control box.

[0077] For the outdoor unit, a terminal box 17 is often provided, and the terminal inside the box is connected to the external circuit. Similarly, in order to prevent the refrigerant leaking from the compressor assembly 2 from flowing into the terminal box 17, the terminal box 17 is not connected to the second chamber 8 and the third chamber 9.

[0078] In this application, if attached Figure 9-11As shown, the terminal box 17 is located at the upper part of the third chamber 9 and is connected to the bottom end of the electric control box 10. The terminal box 17 is also connected to the side panel 12. The side of the terminal box 17 facing the side panel 12 is a wiring opening. Correspondingly, the side panel 12 is provided with a wiring window 122. The wiring window 122 is opposite to the wiring opening, so that the operator can operate the wiring terminal outside the outdoor unit. The side plate 12 is provided with an electrical cover plate 124 to shield the wiring window 122 and the wiring opening. Specifically, the side plate 12 is provided with a mounting groove 121, and the mounting groove 121 extends to the top of the side plate 12. The wiring window 122 is arranged in the mounting groove 121. A limiting groove is formed between the top plate 16 of the outdoor unit and the mounting groove 121. The electrical cover plate 124 is installed in the mounting groove 121 in a detachable manner. The top of the electrical cover plate 124 can extend into the limiting groove. At the same time, the electrical cover plate 124 can completely cover and shield the wiring window 122, thereby improving the assembly reliability of the electrical cover plate 124 on the one hand, and preventing rainwater from entering the interior of the outdoor unit (such as the interior of the wiring terminal box 17) from the wiring window 122 of the side plate 12 on the other hand, thereby improving the waterproof performance of the outdoor unit, and further improving the safety performance of the outdoor unit. For the electrical cover plate 124, it is preferably connected to the mounting groove 121 of the side plate 12 by fasteners.

[0079] Waterproof bosses 123 are arranged around the wiring window 122 to further improve the waterproof performance of the wiring window 122 of the side plate 12. The electrical cover 124 is provided with a buckle 125 and a wiring portion 126, the wiring portion 126 protrudes toward the outside of the outdoor unit, and a wiring channel with an opening downward is formed between the wiring portion 126 and the side plate 12, thereby facilitating the connection between the wiring terminal and the external circuit and preventing rainwater from entering the interior of the outdoor unit.

[0080] Example 3

[0081] This embodiment further improves the overall external structure of the outdoor unit based on Embodiment 1 or Embodiment 2.

[0082] As attached Figure 10-16As shown, the outdoor unit includes a front panel 13 and a decorative panel 18, and the decorative panel 18 is connected to the front panel 13 at least in a snap-on manner; specifically, the front panel 13 is provided with a snap-on interface 133, and the decorative panel 18 is provided with a claw 183 on the side facing the front panel 13, and the claw 183 can penetrate the snap-on interface 133 and snap-on with the snap-on interface 133. Thus, by providing the decorative panel 18, it is beneficial to improve the aesthetics of the outdoor unit, and at the same time, the decorative panel 18 can be disassembled and assembled, which is convenient for daily disassembly and maintenance, or replacement of the decorative panel 18. Accordingly, the decorative panel 18 can be connected to the housing structure of the outdoor unit by fasteners on the basis of snap-on connection with the front panel 13, such as: the decorative panel 18 and the front panel 13 are further connected and fixed by screws.

[0083] The inner wall of the front panel 13 is provided with a groove 134, the groove 134 is located below the card interface 133, the groove 134 is recessed toward the decorative plate 18, and the end of the claw 183 (i.e., the end away from the decorative plate body) is engaged with the groove 134, thereby facilitating the reliability of the engagement between the decorative plate 18 and the front panel 13. For the installation and fixation between the front panel 13 and other housing structures (such as the chassis 11, the side panel 12, and the top panel 16), reference can be made to the prior art, and this application will not elaborate on it.

[0084] The decorative plate 18 is provided with an abutment column 184 on one side facing the front panel 13 . When the decorative plate 18 is engaged with the front panel 13 , the end of the abutment column 184 away from the decorative plate 18 abuts against the front panel 13 , thereby further improving the assembly reliability between the decorative plate 18 and the front panel 13 .

[0085] Since three chambers are arranged inside the outdoor unit of the present application, in order to facilitate the separate disassembly and maintenance of the interior of each chamber, the front panel 13 in the present application can be provided as only one whole piece, or at least two pieces, for example, two or three pieces, and accordingly, the number of decorative panels 18 can also be provided as at least two pieces, or can correspond one to one with the number of front panels 13. Of course, at least two front panels 13 can also be provided, but only one whole decorative panel 18 can be provided. Regardless of the number of front panels 13 and decorative panels 18, the clamping structure between the front panels 13 and decorative panels 18 proposed in the present embodiment can be adopted.

[0086] As a preferred solution of this embodiment, the front panel 13 is provided with two pieces, which are respectively denoted as a first front panel 131 and a second front panel 132. The first front panel 131 serves as a separate front panel of the first chamber 7, and the second front panel 132 serves as a common front panel for the second chamber 8 and the third chamber 9. Correspondingly, the decorative panel 18 is also provided with two pieces, which are respectively denoted as a first decorative panel 181 and a second decorative panel 182. The first decorative panel 181 is snap-fitted to the first front panel 131, and the second decorative panel 182 is snap-fitted to the second front panel 132.

[0087] However, for the split decorative panel structure, there is often a large gap between two adjacent decorative panels, and the decorative panel installation reliability is poor. For any two adjacent decorative panels, this embodiment is described by taking the first decorative panel 181 and the second decorative panel 182 as examples for the convenience of description. The first decorative panel 181 is provided with an assembly flange 1811 on the side close to the second decorative panel 182, and the assembly flange 1811 is provided with a clamping hole 1812. The second decorative panel 182 is provided with a buckle 1821 on the side close to the first decorative panel 181, and the buckle 1821 is clamped with the clamping hole 1812. Thus, the closeness between the two adjacent decorative panels can be effectively improved, and the gap between the two after being assembled with the front panel structure can be reduced, ensuring the overall aesthetics of the decorative panel structure. At the same time, when the decorative panel structure is connected to the front panel structure, the two adjacent decorative panels are additionally clamped, which is conducive to further improving the assembly reliability of the decorative panel structure.
