Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a valve assembly includes: a first insulating ring 10; a second insulating ring 20; the stop valve 30 is arranged in an outdoor unit of the air conditioner, one end of the first insulating ring 10 is sleeved at the first end of the stop valve 30, and the other end of the first insulating ring 10 is sleeved at an outdoor unit pipeline, so that the stop valve 30 is in insulated connection with the outdoor unit pipeline; a conductive refrigerant pipe 40 connected to the second end of the stop valve 30; the angle valve 50 is arranged in an indoor unit of the air conditioner, one end of the second insulating ring 20 is sleeved at the first end of the angle valve 50, the other end of the second insulating ring 20 is sleeved at an indoor unit pipeline, so that the angle valve 50 is in insulated connection with the indoor unit pipeline, and the second end of the angle valve 50 is connected with the conductive refrigerant pipeline 40; an outdoor unit power line 60 disposed on the stop valve 30 for connecting an external signal source; and an indoor unit power line 70 provided to the angle valve 50 for connecting an external signal source.
Specifically, the conductive refrigerant pipe 40 is a pipe having a conductive function and used for transmitting a refrigerant. The shut-off valve 30, also called a shut-off valve, is a forced sealing type valve, so that when the valve is closed, pressure must be applied to the valve flap to force the sealing surface not to leak. The angle valve 50 is also called an angle type stop valve, and the angle valve 50 is similar to a ball valve, and the structure and characteristics thereof are modified from those of the ball type valve; the difference from a globe valve is that the outlet of the angle valve 50 is at a 90 degree right angle to the inlet. The stop valve 30 and the angle valve 50 provided in this embodiment have a certain conductive function, and when power or other signals are applied to the stop valve 30 or the angle valve 50, the power or control signals can be transmitted to the conductive refrigerant pipe 40 or the power line of the indoor unit (outdoor unit) connected thereto.
In a conventional air conditioner, a power supply signal and other control signals between an indoor unit and an outdoor unit need to be realized by designing a corresponding communication line between the indoor unit and the outdoor unit; in the solution of this embodiment, the refrigerant pipeline connecting the indoor unit and the outdoor unit is used as a transmission medium for electric energy or other control signals, and the information interaction between the indoor unit and the outdoor unit is realized by using the conductive refrigerant pipeline.
In order to avoid that the transmission of signals is interfered and the signals cannot be normally transmitted between the indoor unit and the outdoor unit when the refrigerant pipeline is used as a signal transmission medium, the scheme of the embodiment also performs insulation treatment on one end of the stop valve 30 connected with the outdoor unit pipeline in the outdoor unit, and the outdoor unit pipeline is in insulation sleeve joint with the first end of the stop valve 30 by using the first insulation ring 10; meanwhile, the end of the diagonal valve 50 connected with the indoor unit pipeline in the indoor unit is subjected to insulation treatment, and the indoor unit pipeline is in insulation sleeve joint with the first end of the diagonal valve 50 by using the second insulation ring 20. By the scheme, when a signal is input into the outdoor unit power line 60 arranged on the stop valve 30, the signal can be finally output by the indoor unit power line 70 arranged on the angle valve 50 through the conductive refrigerant pipeline 40, and when the signal is input into the indoor unit power line 70 arranged on the angle valve 50, the signal can be finally output by the outdoor unit power line 60 arranged on the stop valve 30 through the conductive refrigerant pipeline 40, so that information interaction between the indoor unit and the outdoor unit is realized.
It is understood that, in one embodiment, in order to facilitate the first insulating ring 10 to insulate and sleeve the outdoor unit pipe and the cut-off valve 30, the diameter of the first end of the cut-off valve 30 is identical to the diameter of the outdoor unit pipe. That is, the diameter difference between the two is smaller than a certain diameter threshold (the threshold should be as small as possible), so that when the stop valve 30 is sleeved with the outdoor unit pipe, the situation that the sleeve cannot be stably sleeved due to the too large diameter difference between the two is avoided, and similarly, the diameter of the first end of the angle valve 50 should be substantially the same as the diameter of the indoor unit pipe. In the embodiment, when the diameter of the outdoor unit pipeline is equivalent to the diameter of the stop valve 30, the insulating ring is adopted for sleeving, so that the outdoor unit pipeline and the stop valve have the advantage of being firmer compared with a mode of bonding the outdoor unit pipeline and the stop valve.
It should be noted that the manner of disposing the indoor unit power line 70 on the angle valve 50 and the manner of disposing the outdoor unit power line 60 on the stop valve 30 are not exclusive, as long as the electric energy or other control signals input by the indoor unit power line 70 can be transmitted to the angle valve 50, and finally output through the conductive refrigerant pipe 40, the stop valve 30, etc. and finally through the outdoor unit power line 60; or the electric energy or other control signals input by the outdoor unit power line 60 can be transmitted to the stop valve 30, and finally output through the indoor unit power line 70 via the conductive refrigerant pipe 40, the angle valve 50, and the like.
For example, referring to fig. 2-4, in one embodiment, the valve assembly further includes a first latch 32 and a second latch 51, the first latch 32 is attached to the stop valve 30, the outdoor unit power line 60 is connected to the first latch 32, the second latch 51 is attached to the angle valve 50, and the indoor unit power line 70 is connected to the second latch 51.
Specifically, in the present embodiment, the indoor unit power line 70 and the outdoor unit power line 60 are connected to corresponding positions by a snap connection. Specifically, a first buckle 32 with a power conducting function is arranged at one end, used for being in insulation sleeve joint with an outdoor unit pipeline, of the stop valve 30, a second buckle 51 with a power conducting function is arranged at one end, used for being in insulation sleeve joint with an indoor unit pipeline, of the angle valve 50, and the first buckle 32 and the second buckle 51 are respectively fixed on the stop valve 30 and the angle valve 50 in a threaded connection or rivet connection mode and are tightly attached to the stop valve 30 or the angle valve 50. Finally, the indoor unit power line 70 is connected to the angle valve 50 by means of screws, rivets, etc., and the outdoor unit power line 60 is connected to the shut-off valve 30 by means of screws, rivets, etc.
In other embodiments, the indoor unit power line 70 may be directly connected to the angle valve 50, and the outdoor unit power line 60 may be directly connected to the stop valve 30, and may be specifically implemented by means of conductive adhesive bonding or direct bonding, as long as signal interaction between the indoor unit and the outdoor unit can be implemented.
Referring to fig. 2, in one embodiment, the valve assembly further includes an insulation fixing device 31, the insulation fixing device 31 is disposed on the stop valve 30, and the stop valve 30 is fixedly and insulatively disposed on the outdoor unit through the insulation fixing device 31.
Specifically, the insulation fixing device 31 is a device for fixing the cut-off valve 30 to the outdoor unit and insulating the cut-off valve 30 from the outdoor unit. The stop valve 30 is fixed on the outdoor unit through the insulating fixing device 31, and the stop valve 30 is guaranteed to be completely isolated from the outdoor unit and not conducted after being fixed, so that when signal interaction is carried out between the indoor unit and the outdoor unit, the interaction signal cannot be transmitted to other parts of the outdoor unit, the transmission reliability of the indoor unit and the outdoor unit during signal transmission through the conductive refrigerant pipeline 40 can be effectively guaranteed, and when electric energy transmission is carried out between the indoor unit and the outdoor unit, the risk of electric leakage of the outdoor unit can be effectively reduced through the scheme.
It should be noted that the type of the insulation fixing member 31 is not exclusive, and in one embodiment, the insulation fixing member 31 may be directly made of an insulation material, and the cut-off valve 30 may be fixedly installed in the outdoor unit without direct contact between the cut-off valve 30 and the outdoor unit.
In another embodiment, the insulation fixing device 31 includes a fixing device body and an insulation gasket, the fixing device body is disposed on the stop valve 30, the fixing device body is opened with a fixing hole, the insulation gasket is disposed on the fixing hole, and the stop valve 30 is fixedly connected to the outdoor unit through the fixing hole.
Specifically, this embodiment adopts the mode of insulating gasket to keep apart between outdoor unit and the stop valve 30, specifically includes fixing device body and insulating gasket two parts, and the fixing device body sets up in the stop valve 30, has seted up the fixed orifices at this fixing device body, can carry out threaded connection or rivet connection etc. with the outdoor unit through this fixed orifices. In order to realize the insulation isolation between the stop valve 30 and the outdoor unit, an insulation gasket is arranged in the fixing hole, so that when the fixing device body is in threaded connection or rivet connection with the outdoor unit, the fixing device body is insulated from the outdoor unit, and the insulation between the stop valve 30 and the outdoor unit can be ensured. It is understood that, in one embodiment, in order to ensure a stable connection between the stop valve 30 and the outdoor unit, a plurality of fixing holes (e.g., two fixing holes, etc.) may be formed in the fixing device body, each fixing hole is provided with an insulating gasket, and the insulating connection between the fixing hole and the outdoor unit is realized through a thread or a rivet.
The insulating ring is a ring-shaped device made of non-conductive materials, and the insulating ring can be used for insulating and connecting two pipes with a conductive function and does not influence the flow of gas or liquid between the pipes. It should be noted that the specific types of the first insulating ring 10 and the second insulating ring 20 are not exclusive, and in one embodiment, the first insulating ring 10 and the second insulating ring 20 are the same type of insulating ring (i.e., insulating rings made of the same insulating material). In other embodiments, the specific types of the first insulating ring 10 and the second insulating ring 20 may be different, as long as the insulation between the stop valve 30 and the outdoor unit pipe and the insulation between the angle valve 50 and the indoor unit pipe can be ensured.
Similarly, the specific type of the conductive coolant pipe 40 is not exclusive, and a conductive metal or other conductive material may be used, as long as the transmission of electric energy or other control signals can be achieved. For example, in one embodiment, the conductive coolant line 40 is a copper line.
In the valve assembly, the refrigerant pipeline arranged between the stop valve 30 of the outdoor unit and the angle valve 50 of the indoor unit is the conductive refrigerant pipeline 40, the stop valve 30 is in insulation sleeve joint with the outdoor unit pipeline by using an insulating ring, the angle valve 50 is in insulation sleeve joint with the indoor unit pipeline by using an insulating ring, so that the stop valve 30 is insulated from the outdoor unit pipeline, and the angle valve 50 is insulated from the indoor unit pipeline. And the stop valve 30 is provided with an outdoor unit power line 60, the angle valve 50 is provided with an indoor unit power line 70, and the indoor unit power line 70 and the outdoor unit power line 60 are both connected with corresponding signal sources, so that power supply and signal transmission between the indoor unit and the outdoor unit can be realized through the conductive refrigerant pipeline 40. Through the scheme, no extra power line or signal line is needed to be designed between the indoor unit and the outdoor unit, and the transmission operation of electric energy and other control signals can be realized only through the conductive refrigerant pipeline 40, so that the installation complexity of the air conditioner is effectively reduced.
