Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0020] The inventor found through research that, figure 1 The basic principle of the four-way valve to achieve reversing is to satisfy the following formula: F 高压 -F 低压 >f 摩擦 , where F 高压 Refers to the pressure of the high pressure chamber; F 低压 Refers to the pressure of the low-pressure chamber; f 摩擦 Refers to the friction between the slider and the inner wall of the four-way valve.

[0021] figure 1 During the heating reversing process of the four-way valve, when the slider 15 moves to the middle position, the evaporator inlet 12 of the four-way valve, the compressor suction pipe 13 and the condenser outlet 14 are in a connected state, and the compressor discharge The high-pressure gas in the gas pipe 11 will enter the compressor suction pipe 13 through the gap between the sli...

Abstract

The invention discloses a four-way valve and an air conditioner. The four-way valve includes a valve body, a slider and an electromagnetic actuator. The slider is movably arranged in the valve cavity of the valve body. The electromagnetic actuator is connected to the valve body. The electromagnetic actuator drives the slider to cool in the valve cavity. switch between the heating position and the heating position. The present invention adopts the method of "electro-magnetic-force" to control the commutation. Therefore, it is only necessary to ensure that the magnetic force between the electromagnetic actuation part and the slider is greater than the friction force between the slider and the inner wall of the four-way valve when the machine is turned on. After the commutation is completed, there will be no problem of commutation stuck. In addition, since the electromagnetic actuating part is energized, the reversing can be completed, and there is no problem of cooling before the reversing, which solves the problem of slow heating, and the four-way valve in the present invention has completed the reversing before the compressor is turned on. Direction, there is no problem of liquid hammer and cross-gas, and the commutation noise is also greatly reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a four-way valve and an air conditioning device. Background technique [0002] figure 1 A working principle diagram of a four-way valve in the prior art is shown. Such as figure 1 As shown, a slide block 15 and pistons 18 located at both ends are installed in the valve body of the four-way valve, wherein each piston 18 is connected to one end of the slide block 15 through a connecting rod 19 respectively. The upper end of the valve body is connected with the compressor discharge pipe 11, and the lower side is respectively connected with the evaporator inlet 12, the compressor suction pipe 13 and the condenser outlet 14. In addition, the compressor discharge pipe 11 is connected with a slide valve 20, wherein the slide valve 20 is controlled by an electromagnetic coil 21, and one valve port of the slide valve 20 is connected with the cavity on the left side of the pist...
