Embodiment Construction

[0049] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and the present invention is not limited to the following specific embodiments.

[0050] In the related art, the four-way valve includes a main valve and a pilot valve, and the high-pressure refrigerant and the low-pressure refrigerant on both sides of the spool of the main valve communicate with the pilot valve through refrigerant pipelines. Among them, the spool of the pilot valve moves back and forth depending on the refrigerant pressure and the pressure difference of the spring elastic force on the pilot valve, the spool of the main valve and the spool of the pilot valve both reciprocate and are easy to get stuck; The flow of refrigerant in the pipeline between the pilot valve and the main valve is prone to t...

Abstract

The invention provides a four-way valve and an air conditioner, and relates to the technical field of air conditioners. The four-way valve comprises a valve body and a communication element, wherein an empty cavity is formed in the valve body, and a first port, a second port, a third port and a fourth port which are sequentially formed in the circumferential direction of the valve body are formedin the valve body; and the communication element is arranged in the empty cavity, and capable of rotating relative to the valve body, so that the first port communicates with the second port, and thethird port communicates with the fourth port, or, the first port communicates with the fourth port, and the second port communicates with the third port. The four-way valve is not liable to be blocked, and the problem of refrigerant leakage is also not easily caused.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a four-way valve and an air conditioner. Background technique [0002] The four-way valve is often used in air conditioners to switch the cooling and heating states of the air conditioner. The four-way valve is provided with four ports, which are respectively connected to the exhaust port of the compressor, the suction port of the compressor, the condenser and the evaporator. [0003] The main valve of the four-way valve includes a valve body and a spool in the valve body. The two sides of the spool can be respectively fed with high-pressure refrigerant and low-pressure refrigerant. The pressure difference between the high-pressure refrigerant and the low-pressure refrigerant pushes the spool along the The length direction of the valve body moves back and forth to realize the connection between different ports. [0004] However, the spool is easily stuck in the valve bo...
