Problems solved by technology

The reliability and component utilization of the refrigeration system of this conventional ice maker is reduced due to the introduction of more components and lines, such as solenoid valves W1, W2, reservoir O, etc.
In addition, since the ice machine needs to switch from the cooling mode to the heating mode after the ice making process is over, so that the ice will fall off from the ice making part (that is, the evaporator T), so if there are more parts and pipelines, the The greater the power loss and flow loss caused by switching the refrigerant fluid between high pressure and low pressure during the switching process, further reducing the efficiency of the refrigeration system

Embodiment Construction

[0025] As shown in Figures 3a, 3b, 7a, and 7b, the four-way valve M of the present invention includes a pilot valve X, a main valve Y, and an electromagnetic coil Z. The main valve Y has a valve body 20 and a valve cavity formed by the valve body 20 . Inside the valve chamber, the slide seat 25 is integrally formed with the valve body 20 . The slider 103 can reciprocally slide on the slider 25 , wherein a concave cavity 30 is provided on the sliding contact surface 31 of the slider 103 facing the slider 25 .

[0026] Two piston elements 26 are respectively connected to the slider 25 on both sides of the slider 25 . The two piston elements 26 are assembled in the valve cavity to cooperate with the wall of the valve cavity, and the two piston elements 26 can be integrated with the slide block 103 to reciprocate in the valve cavity, that is, they can be positioned at the valve cavity. The body 20 moves between a first position at the left end and a second position at the right ...

Abstract

A 4-way valve and an ice maker using the 4-way valve are disclosed. Said 4-way valve has a valve body, a slide track integrated with said valve body, and a valve core which can move between the first position and the second position and has a slide block which can slide on said slide track and has a concave cavity on the sliding surface. The first port is on the valve body and the second, third and forth ports are on the slide track. Said ports on the slide track have the radial flanges to ensure that only two of them are communicated to each other when the slide block is positioned at the first or second position.

Description

technical field [0001] The invention relates to a four-way valve used in a refrigerant circulation system, in particular to a main valve used for the four-way valve. The invention also relates to an ice maker using the four-way valve. Background technique [0002] A conventional four-way valve is widely used in a refrigerant circulation system such as a refrigeration system in order to change a flow path of refrigerant. Fig. 9a shows a main valve in a four-way valve used in a refrigerant cycle system in the prior art. Wherein, the slide block 103a slides between the first position and the second position on the slide seat 25a, when in the first position, the slide block 103a slides to the left, the first port 93 communicates with the fourth port 97, and the third port 96 is in communication with the second port 95; in the second position, the slider 103a slides to the right, the first port 93 is in communication with the second port 95, and the third port 96 is in communic...
