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

[0002] The patent application with application number 202110506578.4 proposes an air conditioner and related valve components powered by a refrigerant connecting pipe. The refrigerant metal connecting pipe is used to power the outdoor unit, completely eliminating the connecting wires and cables. However, the upper stop valve and the lower stop valve of the outdoor unit are no longer insulated, but are energized, and there is also a high potential difference between the two. The general air conditioner stop valve protection is designed for cable power supply. The stop valve is not energized, and only basic physical protection is required, without considering foreign object electric shock and electrical safety protection between the stop valves. Therefore, for air conditioners powered by refrigerant connecting pipes, the existing stop valve protection device cannot meet the safety requirements.

[0003] When the refrigerant pipe is used for power supply, the high and low pressure stop valves of the outdoor unit carry different electrical signals. The traditional stop valve protective cover has a large gap in the outlet direction of the refrigerant pipe, which may cause foreign matter and even small animals to enter. During refrigeration, there will generally be condensed water on the high and low pressure stop valves. If the impurities accumulated there are moistened by the condensed water, the insulation between the high and low pressure stop valves will decrease, resulting in electrical safety hazards such as sparks and short circuits.

[0027] To further illustrate the technical solution of the present invention, Figure 1-Figure 5 , the following specific embodiments are provided.

[0028] Example 1

[0029] In this embodiment, a protective cover for a stop valve of an air conditioner outdoor unit is provided. Figure 1-Figure 4 As shown, the outdoor unit is provided with a first stop valve 1 and a second stop valve 2, the protective cover 3 is an insulating cover, a accommodating space and an insulating partition 4 which divides the accommodating space into two chambers are provided inside the protective cover 3, and an opening communicating with the accommodating space is provided on one side of the protective cover 3, wherein one chamber is used to accommodate the first stop valve 1, and the other chamber is used to accommodate the second stop valve 2, and a drain outlet 31 is provided at the bottom of the two chambers.

[0030] In this embodiment, the drain outlets 31 can be formed on the surface of the protective cover 3 and communicate with the external environment, so that the condensed water generated on the surface of the stop valve during air conditioning cooling can be directly discharged to the outside. Alternatively, the drain outlets 31 can be opened on the insulating partition 4 so that the drain outlets 31 of the two chambers are communicated, and the other drain outlet 31 is directly communicated with the external environment.

[0031] Preferably, the insulating partition 4 is arranged transversely and tilted in the accommodating space to form an upper chamber 32 and a lower chamber 33, one of the two chambers is the upper chamber 32, and the other is the lower chamber 33. The drain port 31 of the upper chamber 32 is formed at the lowest position of the insulating partition 4 and communicates with the drain port 31 of the lower chamber 33. The drain ports 31 of the two chambers are located on one side of the protective cover 3. Furthermore, an inclined surface is formed at the bottom of the lower chamber 33, and the drain port 31 of the lower chamber 33 is located at the lowest position of the inclined surface. By arranging the insulating partition 4 transversely and tilting it at the same time, the drain port 31 can avoid short circuit caused by excessive water accumulation in the two chambers. At the same time, the number of openings on the outer surface of the protective cover 3 is reduced to improve safety.

[0032] In this embodiment, the first stop valve 1 is a high-pressure stop valve of the air conditioner outdoor unit, and the second stop valve 2 is a low-pressure stop valve; alternatively, the first stop valve 1 is a low-pressure stop valve, and the second stop valve 2 is a high-pressure stop valve.

[0033] Insects or reptiles are easy to enter the drain port of the protective cover 3, so a net is provided on the protective cover 3 to cover the drain port 31. The net can be a net with a smaller mesh number to prevent insects from entering, and can also block dust from entering the protective cover. The mesh number of the net can be a sieve with a mesh number greater than or equal to 10, which can block most insects from entering. At the same time, since the sieve aperture is relatively small, condensed water can flush the sieve, thereby preventing a large amount of dust from entering the protective cover 3 from the drain port to form a short-circuit bridge in dusty places.

[0034] The two chambers of the protective cover 3 are respectively provided with a refrigerant pipe introduction hole 34. The two refrigerant pipes 5 led out from the air-conditioning indoor unit are respectively connected to the first stop valve 1 and the second stop valve 2 through the refrigerant pipe introduction holes 34 of the two chambers. Each of the refrigerant pipes 5 forms a sealed connection with the refrigerant pipe introduction hole 34 to prevent small animals from crawling into the protective cover 3 through the refrigerant pipe introduction hole, while also blocking external dust from entering the protective cover 3, thereby improving the safety performance of the protective cover 3.

[0035] The refrigerant pipe 5 is provided with a heat-insulating layer on the outside, and the heat-insulating layer is embedded in the refrigerant pipe introduction hole 34 and adheres to the inner wall of the refrigerant pipe introduction hole 34 .

[0036] In one embodiment, a sealing ring may be used to seal the refrigerant pipe and the refrigerant pipe introduction hole 34 .

[0037] In a preferred embodiment, the diameter of the refrigerant pipe introduction hole 34 is larger than the diameter of the corresponding refrigerant pipe 5, and smaller than the diameter of the corresponding refrigerant pipe insulation layer. By utilizing the elasticity of the insulation layer, the insulation layer is squeezed into the refrigerant pipe introduction hole 34 to form an expansion connection, which plays a sealing role and also saves the use of materials.

[0038] Example 2

[0039] This embodiment provides an air conditioner outdoor unit, such as Figure 4 and Figure 5 As shown, it includes a protective cover for a stop valve of an air conditioner outdoor unit as described in Example 1.

[0040] Specifically, the air conditioner outdoor unit also includes: an outer shell 6, on which a side plate 7 is provided, and an opening is provided on the side plate 7; a first stop valve 1 is arranged at the opening position of the side plate 7 in the outer shell 6, and protrudes out of the outer shell 6 from the opening; a second stop valve 2 is arranged at the opening position of the side plate 7 in the outer shell 6, and protrudes out of the outer shell 6 from the opening; the protective cover 3 covers the side plate 7 at the opening, and the first stop valve 1 and the second stop valve 2 are located in two chambers.

[0041] Further, the protective cover 3 is detachably sealed and fixed on the side plate 7 to facilitate disassembly and maintenance, and also plays a role in dust prevention to avoid internal short circuit. Optionally, after the protective cover 3 is clamped on the side plate 7, it is fixedly connected to the side plate 7 by screws.

[0042] The exemplary embodiments of the present disclosure are specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
