Description

Technical Field

[0001] The present invention relates to the technical field of household appliance parts, and in particular to an anti-condensation valve gasket, a valve assembly having the same, and an air-conditioner outdoor unit. Background Art

[0002] The large and small stop valves of the air conditioner outdoor unit will produce a lot of condensation water under condensation conditions. The reason is that the coldness of the large and small valves is transferred to the valve mounting frame, and condensation water is generated on the surface of the valve mounting frame and flows down to the outside of the machine. The indoor / outdoor dry-bulb / wet-bulb temperature is 27 degrees Celsius / 24 degrees Celsius. The large and small valves are cold inside and hot outside, and condensation water condenses on the outside. Some areas where the air conditioner outdoor unit is exported, such as Thailand, require that the outdoor unit cannot drip, so a valve cover is added to drain the condensation into the chassis. However, there is still a hidden danger that the large and small stop valves and valves directly produce condensation water and drip. Therefore, it is urgent to provide a technical solution to solve the problem of large and small stop valves and valves directly producing condensation water and dripping. Summary of the invention

[0003] In view of this, the present invention provides an anti-condensation valve gasket, a valve assembly and an air-conditioning outdoor unit having the same. The structure of the anti-condensation valve gasket is designed to achieve the function of isolating cold transfer and drainage of the valve assembly. The air-conditioning outdoor unit having the valve assembly does not have the technical problem of dripping from the outdoor unit, and has a high degree of commonality, reducing the cost of rectification.

[0004] Specifically: the present invention provides an anti-condensation valve gasket, the gasket forms a flared shell with a preset thickness; the flared shell includes a top surface formed in a vertical direction in the thickness direction, a first drainage edge arranged around the outer periphery of the top surface, and a second drainage edge arranged around the outer periphery of the first drainage edge; the first drainage edge is an inclined edge, and the second drainage edge forms the lowest position point of the shell structure;

[0005] The shell is also provided with a notch, which starts from the outer edge of the first guide edge and extends to the position where the valve is installed on the top surface of the shell. The notch forms a downwardly inclined first guide surface on the lower section of the shell.

[0006] Further optionally, the angle between the first drainage edge and the second drainage edge is greater than 90 degrees and less than 180 degrees; the two cooperate to form a V-shape to play a drainage role.

[0007] Further optionally, the second drainage edge is an inclined surface.

[0008] Further optionally, the notch forms an inner arc section at the position where the valve of the housing is installed, and the diameter of the inner arc section is larger than the valve installation diameter.

[0009] Further optionally, the notch forms a second flow guiding surface on the upper section of the shell, which is inclined downward and extends to the second flow guiding edge.

[0010] Further optionally, a protrusion protruding outward is formed on the top surface to reduce contact and avoid the generation of condensation.

[0011] The present invention also provides a valve assembly, which includes a valve, a valve mounting frame, and a valve cover. The valve is mounted on the valve mounting frame, the valve cover covers the outside of the valve, and a water accumulation trough is formed below the valve. The anti-condensation valve gasket described in any one of the above items is arranged between the valve and the valve mounting frame.

[0012] Further optionally, the projection of the lowest point of the shell structure formed by the second drainage edge falls within the water collection groove, ensuring that condensation generated on the side of the gasket in contact with the valve flows into the water collection groove of the valve cover.

[0013] Further optionally, the valve includes a large valve and a small valve, and the anti-condensation valve gasket is provided on both the large and small valves, and the large valve is installed below the small valve, and the gasket thickness of the small valve is greater than the gasket thickness of the small valve, ensuring that condensation flows into the anti-condensation valve gaskets on the large and small valves.

[0014] The present invention also provides an air-conditioning outdoor unit, which adopts the anti-condensation valve gasket or valve assembly described in any one of the above items.

[0015] Beneficial effect: The anti-condensation valve gasket provided by the present invention can play the role of heat insulation and drainage. The valve assembly thereof can contain condensation water in the water storage groove of the valve cover. Applying it to the outdoor unit of the air conditioner can not only effectively solve the problem of dripping of the outdoor unit, but also has strong versatility, avoids modification of the outdoor unit and reduces costs.

[0026] The following is combined with Figure 1-3 The contents of the specific implementation modes of the present invention are described in detail:

[0027] Example 1

[0028] like Figure 1As shown, this embodiment provides an anti-condensation valve gasket 4, the gasket forms a flared shell with a preset thickness; the flared shell includes a top surface 45 formed in the vertical direction in its thickness direction, a first drainage edge 42 arranged around the outer periphery of the top surface 45, and a second drainage edge 43 arranged around the outer periphery of the first drainage edge 42; the first drainage edge 42 is an inclined edge, and the second drainage edge 43 forms the lowest position point of the shell structure; the shell also has a notch 44, which starts from the outer edge of the first drainage edge 42 and extends to the position where the valve is installed on the top surface 45 of the shell, and the notch 44 forms a downwardly inclined first guide surface 46 on the lower section of the shell. The anti-condensation valve gasket 4 mainly plays the role of drainage, and the condensation on the side of the gasket that contacts the valve flows along the drainage edge to the lowest position point of the shell structure by designing the angles of the first drainage edge and the second drainage edge.

[0029] In order to enhance the drainage effect of the gasket, preferably, the angle between the first drainage edge 42 and the second drainage edge 43 is greater than 90 degrees and less than 180 degrees; further preferably, the angle between the first drainage edge 42 and the second drainage edge 43 is 150 degrees. Preferably, the second drainage edge 43 is an inclined surface, and the second drainage edge 43 is inclined outward relative to the shell as a whole. Preferably, the notch 44 forms an inner arc section at the position where the valve of the shell is installed, and the diameter of the inner arc section is greater than the valve installation diameter; it is ensured that the valve can be fixedly installed in cooperation with the valve. In order to ensure that the condensation generated by the notch 44 will not fall, preferably, the notch 44 forms a second guide surface 47 on the upper section of the shell that is inclined downward and extends to the second drainage edge 43. In order to reduce the generation of condensation, preferably, a protrusion 41 protruding outward is formed on the top surface 45 to prevent the top surface 45 from contacting the valve installation position to generate condensation. Further preferably, at least two protrusions 41 are provided.

[0030] The anti-condensation valve gasket 4 provided in this embodiment can play the role of heat insulation and drainage.

[0031] Example 2

[0032] like Figure 2-3 As shown, the present embodiment provides an air-conditioning outdoor unit, whose stop valve assembly includes a large valve 3 and a small valve 2, a valve mounting frame 1, and a valve cover 5. The valve is mounted on the valve mounting frame 1, and the valve mounting frame 1 is mounted on the chassis of the air-conditioning outdoor unit. The valve cover 5 covers the outside of the valve, and a water collection tank 51 is formed below the valve. The anti-condensation valve gasket 4 in Example 1 is provided between the valve and the valve mounting frame 1. In order to prevent condensation from falling into the outdoor unit, preferably, the second drainage edge 43 forms the lowest position point of the shell structure and the projection falls into the water collection tank 51; to ensure that the condensation generated on the side of the gasket in contact with the valve flows into the water collection tank 51 of the valve cover 5. In order to ensure that the condensation on the anti-condensation valve gasket 4 on the large and small valves 2 flows into the water collection tank 51 of the valve cover 5, as shown Figure 3As shown in the preferred embodiment, the large valve 3 is installed below the small valve 2, and the thickness of the gasket of the small valve 2 is greater than the thickness of the gasket of the large valve 3, that is, there is a difference H; it is ensured that the condensation on the anti-condensation valve gasket 4 on the large and small valves 2 flows into. The definition of large and small valves 2 is relative, not absolute, and the valve of a specific size can be selected according to the actual situation. Further preferably, the thickness difference H is not less than 3mm.

[0033] When the outdoor unit of the air conditioner is operating in condensation mode, the top surface 45 of the gasket is separated from the valve mounting frame 1 by the protrusion 41, so the valve mounting frame 1 will not produce condensation water. If condensation water is produced on the side of the gasket in contact with the valve, it can also be introduced into the water storage groove 51 of the valve cover 5 along the first drainage edge 42 and the second drainage edge.

[0034] Specifically, the side of the anti-condensation valve gasket 4 that contacts the valve, this part drains water due to the design angles of the first drainage edge 42 and the second drainage edge 43. Based on this design, the second drainage edge 43 is the lowest point, and the anti-condensation valve gasket 4 of the small valve 2 is thicker than the anti-condensation valve gasket 4 of the large valve 3, and the lowest position of the shell structure formed by the second drainage edge 43 is within the vertical range of the water accumulation groove 51 of the valve cover 5, which can reliably ensure that condensation water flows into the valve cover 5.

[0035] The air-conditioning outdoor unit provided in this embodiment has a valve assembly that ensures that when it is operating in condensing conditions, condensation flows into the water collection groove of the valve cover through the anti-condensation valve gasket, which not only effectively solves the problem of dripping water from the outdoor unit, but also has strong versatility in structure, avoids modification of the outdoor unit and reduces costs.

[0036] In summary, the present invention provides an anti-condensation valve gasket, which forms a flared shell with a preset thickness; the flared shell includes a top surface formed in the vertical direction in the thickness direction, a first drainage edge arranged around the outer periphery of the top surface, and a second drainage edge arranged around the outer periphery of the first drainage edge; the first drainage edge is an inclined edge, and the second drainage edge forms the lowest position point of the shell structure; the shell is also provided with a notch, which starts from the outer edge of the first drainage edge and extends to the position where the valve is installed on the top surface of the shell, and the notch forms a downwardly inclined first guide surface on the lower section of the shell. The valve assembly with the gasket can flow the generated condensation into the water storage tank of the valve cover, and the air conditioner outdoor unit with the gasket will not have the problem of dripping of the outdoor unit, thereby improving the user experience, and the cost is low and the versatility is strong.

[0037] 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.
