Description

Technical Field

[0001] The utility model relates to the technical field of air processing equipment, in particular to a valve body component and an air conditioning unit. Background Art

[0002] Traditional air conditioning refrigerants cause the greenhouse effect. As environmental protection requirements increase, air conditioning manufacturers are vigorously promoting the switch to new refrigerants. New environmentally friendly refrigerants such as R32 and R454B are flammable refrigerants. In order to ensure safe use, safety protection devices need to be designed for extreme situations when designing such air conditioning products.

[0003] Products using flammable refrigerants must be equipped with refrigerant leak sensors. When a leak occurs, the system shuts down and power is removed, waiting for on-site repair personnel. This can take a long time, from the time the leak is detected and the system automatically shuts down until repair personnel arrive. During this time, the refrigerant continues to leak until all the refrigerant is gone. Directly discharging flammable refrigerants into the air can pose a safety hazard if there is an ignition source nearby. Furthermore, refrigerants are toxic and pose a health hazard.

[0004] Although existing technology has built-in shut-off valves for connecting indoor and outdoor units during engineering installation, they are all mechanical and require manual operation using tools such as wrenches to open and close. These operations are only performed by professionals and not by ordinary users. To address this issue, an electric ball valve is usually added to the connecting pipe between the indoor and outdoor units. In the event of a leak, the valve automatically closes, blocking the connection between the indoor and outdoor units. Refrigerant on either the indoor or outdoor unit side can leak out independently, reducing refrigerant leakage. Electric ball valves are large in size, and a large space must be reserved in the structural design of air conditioner products to accommodate them. With the trend toward miniaturization and lightweighting of air conditioners, piping space is compact, making it difficult to add more functional components within the limited housing size. Many products cannot achieve this function, and the added parts assembly process is inefficient. Utility Model Content

[0037] Although existing technology has built-in shut-off valves for connecting indoor and outdoor units during engineering installation, they are all mechanical and require manual operation using tools such as wrenches to open and close. These operations are only performed by professionals and not by ordinary users. To address this issue, an electric ball valve is usually added to the connecting pipe between the indoor and outdoor units. In the event of a leak, the valve automatically closes, blocking the connection between the indoor and outdoor units. Refrigerant on either the indoor or outdoor unit side can leak out independently, reducing refrigerant leakage. Electric ball valves are large in size, and a large space must be reserved in the structural design of air conditioner products to accommodate them. With the trend toward miniaturization and lightweighting of air conditioners, piping space is compact, making it difficult to add more functional components within the limited housing size. Many products cannot achieve this function, and the added parts assembly process is inefficient.

[0038] To this end, this application provides a Figures 1 to 7 The valve body assembly shown includes: a mounting plate 1; two stop valves, both of which are arranged on the mounting plate 1, and one stop valve is arranged on the liquid pipe of the outdoor unit, and the other stop valve is arranged on the gas pipe of the outdoor unit; the stop valve includes: a valve body, a fluid channel is arranged in the valve body; an electric valve core structure, the electric valve core structure is arranged on the valve body, and the electric valve core structure has a first state of blocking the fluid channel and a second state of opening the fluid channel; a manual valve core structure, the manual valve core structure is arranged on the valve body, and the manual valve core structure has a third state of blocking the fluid channel and a fourth state of opening the fluid channel. An electric valve core structure and a manual valve core structure are arranged on the valve body, so that the stop valve can realize automatic control and manual control at the same time, thereby overcoming the problem in the prior art that only a manual stop valve is arranged but cannot be used for operation. The stop valve can be directly disconnected and controlled by signal sensing, thereby effectively reducing the leakage of refrigerant and improving user safety. In addition, the two stop valves for the liquid pipe and the gas pipe are integrated on the mounting plate 1. During installation, it is only necessary to set the mounting plate 1 on the outdoor unit. There is no need to separately install the electric ball valve used in the prior art, thereby effectively reducing the space occupied by the valve body assembly, thereby reducing the space occupied by the air-conditioning unit, and there is no need to separately install the electric ball valve, thereby reducing the assembly difficulty of the air-conditioning unit and improving the assembly efficiency of the air-conditioning unit.

[0039] The valve body includes a first valve portion 2 and a second valve portion 3. The electric valve core structure is disposed within the first valve portion 2, and the manual valve core structure is disposed within the second valve portion 3. The first valve portion 2 is located on the first side of the mounting plate 1, and the second valve portion 3 is located on the second side of the mounting plate 1. By disposing the second valve portion 3 on the second side of the mounting plate 1, the manual valve core structure is exposed to the exterior of the outdoor unit, facilitating operation by professionals. Meanwhile, the automatic valve core structure can be concealed by the mounting plate 1 and housed within the outdoor unit, preventing user error. Furthermore, professionals can perform maintenance directly via electrical signals, ensuring the reliability of the air conditioning unit.

[0040] Specifically, the outdoor unit has a housing having a mounting opening formed therein. The mounting plate 1 is disposed at the mounting opening, and the first valve portion 2 is located within the housing, while the second valve portion 3 is located outside the housing. When the valve body assembly is used, the second side of the mounting plate 1 is directed toward the interior of the outdoor unit and the first side is directed toward the exterior of the outdoor unit. In this case, the automatic portion, formed by the electric valve core structure and the first valve portion 2, is enclosed within the outdoor unit, preventing the automatic portion from being exposed to the exterior of the outdoor unit and potentially being misoperated. A professional operator can also directly operate the automatic portion via an electrical control signal. Therefore, the automatic portion does not need to be disposed on the second side of the mounting plate 1. Since the manual portion, formed by the manual valve core structure and the second valve portion 3, requires manual operation, the second valve portion 3 remains exposed to the exterior of the outdoor unit, facilitating operation by a professional operator. Since the first valve portion 2 is disposed on the first side of the mounting plate 1, the first valve portion 2 occupies less space in the outdoor unit, thereby resolving the problem of a separate electric ball valve occupying a large space in the prior art and effectively reducing the space occupied by the air conditioning unit.

[0041] The electric valve core structure includes a first valve core 41 and an electric mechanism. The first valve core 41 is movably disposed within the first valve portion 2. The electric mechanism is connected to the first valve core 41. When the electric valve core structure is in the first state, the first valve core 41 blocks the fluid passage. When the electric valve core structure is in the second state, the first valve core 41 avoids the fluid passage. The electric mechanism can obtain refrigerant leakage parameters and drive the first valve core 41 to move based on these parameters. When a refrigerant leak is determined, the electric mechanism drives the first valve core 41 to switch to the first state, thereby blocking the liquid and gas pipes connecting the outdoor and indoor units, preventing the increase of refrigerant in the indoor unit, thereby reducing refrigerant leakage and improving user safety. Furthermore, after determining that the refrigerant is leaking, the electronic expansion valve of the indoor unit can be used to seal the liquid pipe of the indoor unit or the stop valve arranged on the liquid pipe connecting the outdoor unit and the indoor unit can be controlled. The compressor of the outdoor unit will continue to run to recover the refrigerant of the indoor unit, further reducing the residual amount of refrigerant. Then, the stop valve on the gas pipe connecting the outdoor unit and the indoor unit can be started to achieve a complete disconnection between the outdoor unit and the indoor unit, and the compressor can be stopped, thereby further reducing the amount of refrigerant leaking into the room.

[0042] The electric mechanism includes a power unit 42 and a valve core connecting rod 43. The power unit 42 is arranged on the first valve core 41, and the power unit 42 is connected to the first valve core 41 through the valve core connecting rod 43. The power unit 42 can obtain the refrigerant leakage parameters. The power unit 42 can drive the valve core connecting rod 43 to move according to the obtained refrigerant leakage parameters. The valve core connecting rod 43 can drive the first valve core 41 to move during the movement, thereby realizing automatic control of the first valve core 41.

[0043] like Figure 1 As shown, a first channel is formed in the first valve portion 2. The cross-section of the first channel is L-shaped. The first valve core 41 is arranged at the corner of the L-shape. The plane where the first channel is located is parallel to the plane where the mounting plate 1 is located. By setting the first channel in an L-shape, it is convenient for the first valve core 41 to enter or exit the first channel from one side of the L-shape, thereby facilitating the arrangement and control of the first valve core 41. The first channel constitutes part of the fluid channel.

[0044] The manual valve core structure includes a second valve core and a manual operating part 52. The manual operating part 52 is arranged on the second valve part 3, and at least part of the manual operating part 52 is exposed to the outside of the second valve part 3. The second valve core is movably arranged in the second valve part 3, and when the manual valve core structure is in the third state, the second valve core blocks the fluid channel. When the manual valve core structure is in the fourth state, the second valve core avoids the fluid channel. The second valve core can be directly manually operated by using the part of the manual operating part 52 exposed to the outside of the second valve part 3. In extreme cases (such as power outages, damage to the electric valve core structure, etc.), the manual operating part 52 can be directly used to drive the second valve core to block the fluid channel to ensure the reliability of the air-conditioning unit. Preferably, the manual operating part 52 is a hexagonal nut, and the operator can directly operate it with a hexagonal wrench.

[0045] The second valve portion 3 is further provided with a fluorine injection nozzle interface 53, which is in communication with the fluid channel. Exposing the fluorine injection nozzle interface 53 to the outside of the outdoor unit facilitates fluorine injection operations on the air conditioning unit during production and maintenance.

[0046] The valve body assembly also includes a side plate, which together with the mounting plate 1 forms a housing cavity. The first valve portion 2 is located within the housing cavity, and the second valve portion 3 is located outside the housing cavity. The side plate and mounting plate 1 together form a housing cavity that completely encloses the electric valve core structure and the first valve portion 2. The side plate also provides a neat structure for the valve body assembly, requiring only a square space on one side of the outdoor unit, avoiding the need for a separate electric ball valve, which would otherwise occupy a large space.

[0047] An air conditioning unit comprises the above-mentioned valve body assembly.

[0048] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
