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 sl...

The invention discloses a four-way valve and an air conditioning device. The four-way valve comprises a valve body, a sliding block and an electromagnetic actuating part, wherein the sliding block is movably arranged in the valve cavity of the valve body; the electromagnetic actuating part is connected with the valve body; and the sliding block is driven by the electromagnetic actuating part to be switched between a refrigeration position and a heating position. According to the four-way valve disclosed by the invention, a direction change is controlled in an electric-magnetic-force manner, so that the direction change can be completed as long as the magnetic force between the electromagnetic actuating part and the sliding block is greater than the friction force between the sliding block and the inner wall of the valve body of the four-way valve during start-up of a compressor, and the problem that the four-way valve is stuck during the direction change can be solved; in addition, the direction change can be completed when the electromagnetic actuating part is powered on, and the phenomenon of refrigeration before the direction change is avoided, so that the problem about slow heating can be solved; and the direction change of the four-way valve is already completed before start-up of the compressor, so that the problems about liquid hammering and random gas flowing can be solved, and the noise of the direction change can be 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. like 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 piston ...
