Description

Heat insulation valve and refrigerator thereof Technical Field The utility model relates to the technical field of refrigerators, in particular to a heat insulation valve and a refrigerator with the heat insulation valve. Background A drain pipe is generally provided in the refrigerator, and has a function of discharging defrost water. In addition, the refrigerator needs to be frequently opened and closed in the using process, and external damp and hot air enters the refrigerator, so that the air pressure in the refrigerator is reduced due to expansion caused by heat and contraction caused by cold, and the refrigerator door is sucked by the refrigerator door and is difficult to open, so that the refrigerator drain pipe also needs to have the function of balancing the air pressure inside and outside the refrigerator. At present, in order to realize the functions, some refrigerators are not provided with valves at the drain pipes, and defrosting water and air can freely enter and exit, but if the valves are not provided, when the refrigerator normally operates, the cold air density inside the refrigerator is greater than the external hot air density, and the cold air inside the refrigerator can escape outside the refrigerator along the drain pipes. Leading to a loss of cool air of the refrigerator and increasing power consumption. In addition, the outside hot and humid air can enter the refrigerator along the drain pipe and frost at the defrosting water drain inlet to block the drain outlet. Some refrigerators are provided with two one-way valves at the drain pipe, wherein one-way valve can be automatically opened when defrosting water is discharged, and the other one-way valve is automatically opened when the air pressure in the refrigerator is smaller than the outside. However, the scheme has a complex structure and high manufacturing and assembly costs. Disclosure of utility model In view of the above technical problems, the present utility model provides an insulating valve. The heat insulation valve is arranged in a refrigerator drain pipe and comprises a valve body, a valve core and a valve body, wherein the valve body is internally provided with a valve cavity, the valve body is further provided with a first communication port and a second communication port which are communicated with the valve cavity, the first communication port is used for being communicated with a water inlet of the refrigerator drain pipe, the second communication port is used for being communicated with a water outlet of the refrigerator drain pipe, the valve core is arranged in the valve cavity and is rotationally connected with the valve body, the first communication port and the second communication port can be communicated through rotation, the first communication port and the second communication port are blocked when rotation is stopped, the valve core rotates around a first axis, and the first axis is not intersected with the axis of the first communication port. With this arrangement, the defrost water is discharged through the refrigerator drain pipe, and the heat insulation valve is installed in the refrigerator drain pipe, which becomes a necessary path for the defrost water to flow. The defrosting water enters the valve cavity through the first communication port, flows out through the second communication port and flows to the outlet of the refrigerator drain pipe. Because the first axis around which the valve core rotates is not intersected with the axis of the first communication port, that is to say, the installation position of the valve core is eccentrically arranged compared with the axis of the valve body, and the defrosting water assembly flows towards the second communication port along the axis of the first communication port, when defrosting water is integrally dripped on the valve core eccentrically arranged, the valve core is integrally stressed to be biased, so that the defrosting water smoothly flows towards the second communication port along with the rotation of the valve core. When the valve core is not stressed, that is, no defrosting water drops, the valve core keeps the first communication opening and the second communication opening to be separated, so that external hot and humid air is prevented from flowing from the second communication opening to the first communication opening, and frosting is avoided. In one embodiment, the valve core comprises a main body and a plurality of stop bodies, wherein the stop bodies are respectively connected to the outer peripheral side of the main body at intervals, and the main body and the first axis are coaxially arranged. In one embodiment, the plurality of stop bodies are arranged at intervals along the circumferential direction of the main body, the stop bodies are correspondingly arranged on two radial side surfaces of the main body in pairs, the stop bodies correspondingly arranged in pairs are located on the same plane, and the planes defined by the
