As shown in
The valve spool 2 is movably disposed in the valve cavity 4, that is, the valve spool 2 is movable in the valve cavity 4, thus, a directional function of the six-way directional valve 100 may be achieved by a movement of the valve spool 2 in the valve cavity 4, thus achieving the directional circulation of the refrigerant in the air conditioner.
Two valve chambers 3 are defined between two moving ends of the valve spool 2 and an inner circumferential wall of the valve cavity 4, so that the valve spool 2 is moved by a pressure difference between the two valve chambers 3, that is, the movement action of the valve spool 2 in the valve cavity 4 is driven by the pressure difference of the two valve chambers 3. Specifically, when a pressure in one of the two valve chambers 3 is relatively higher, the valve spool 2 is moved towards the other valve chamber 3 which has a relatively lower pressure therein, eventually a pressure balance is reached, thus achieving the movement of the valve spool 2 by this method, further achieving the directional control function of the six-way directional valve 100.
Specifically, the pilot valve assembly 5 is connected with the two valve chambers 3 respectively so as to change the pressure in the two valve chamber 3, for example, when the air conditioner needs to be switched between a refrigeration mode and a heating mode, with the pilot valve assembly 5 changing the pressure in the two valve chambers 3, the valve spool 2 is allowed to move towards the valve chamber 3 at the side of a lower pressure, thus achieving a directional control of the six-way directional valve 100, and changing the circulation direction of the refrigerant, thereby achieving the refrigeration function or the heating function of the air conditioner.
As shown in
The valve spool 2 moves so that one of the second connecting pipe 12 and the sixth connecting pipe 16 is communicated with the third chamber 23, the first chamber 21 is communicated with the second connecting pipe 12 or the fourth connecting pipe 14 and the second chamber 22 is communicated with the fourth connecting pipe 14 or the sixth connecting pipe 16, that is, when the second connecting pipe 12 is communicated with the third chamber 23, the first chamber 21 is communicated with the fourth connecting pipe 14, the second chamber 22 is communicated with the sixth connecting pipe 16. When the sixth connecting pipe 16 is communicated with the third chamber 23, the second connecting pipe 12 is communicated with the first chamber 21, and the fourth connecting pipe 14 is communicated with the second chamber 22.
Specifically, with the pilot valve assembly 5 changing the pressure in the two valve chambers 3, the valve spool 2 is allowed to move towards the valve chamber 3 at the side of a lower pressure. For example, when the valve spool 2 moves to the right, as shown in
The first connecting pipe 11 is connected with the air exhaust port 401, the second connecting pipe 12 is connected with the outdoor unit output port 200, the fourth connecting pipe 14 is connected with the air return port 402, the fifth connecting pipe 15 is connected with the outdoor unit input port 300, thus making the six-way directional valve 100 communicated in the refrigerant circulation path of the air-conditioning outdoor unit 1000, so as to facilitate the switch of the flowing direction of the refrigerant.
Two ends of the outdoor heat exchanger 500 are connected with the third connecting pipe 13 and the sixth connecting pipe 16 respectively, thus facilitating the refrigerant to flow through the outdoor heat exchanger 500 to exchange heat with the outdoor environment.
The air-conditioning outdoor unit 1000 is applied in the air conditioner in the following, so as to describe the flowing direction of the refrigerant in the air conditioner in detail.
As shown in
As shown in
With the air-conditioning outdoor unit 1000 according to embodiments of the present disclosure, by connecting the six-way directional valve 100 in series in the refrigerant circulation path of the air-conditioning outdoor unit 1000 to replace the two four-way directional valves connected in series in the ducts in the existing art, so as to reduce the parts connected in series in the ducts of the air-conditioning outdoor unit 1000, not only the cost of the air-conditioning outdoor unit 1000 may be reduced to some extent, the connection of the ducts in the air-conditioning outdoor unit 1000 is also simplified, a structure of the air-conditioning outdoor unit 1000 is optimized, and a connection reliability of the air-conditioning outdoor unit 1000 is improved.
According to some embodiments of the present disclosure, the valve spool 2 includes two barrier blocks 24 spaced from each other and a sliding block 25. In which, two valve chambers 3 are defined between the two barrier blocks 24 and the inner circumferential wall of the valve cavity 4 respectively, thereby facilitating the valve spool 2 to move in the valve cavity 4 to achieve the directional control of the six-way directional valve 100, thus changing the flowing direction of the refrigerant in the air conditioner.
The sliding block 25 is disposed between the two barrier blocks 24, the sliding block 25 is connected with the two barrier blocks 24 through a connecting rod 26 respectively, the first chamber 21 and the second chamber 22 are defined between the sliding block 25 and the same side wall of the valve cavity 4, and the third chamber 23 is defined between the sliding block 25, the two connecting rods 26, the two barrier blocks 24 and the inner circumferential wall of the valve cavity 4. Specifically, after the pilot valve assembly 5 changes the pressure in the two valve chambers 3, the pressure in the valve chamber 3 at the side of a higher pressure drives the barrier block 24 and the barrier block 24 drives the sliding block 25 to move towards the valve chamber 3 at the side of a lower pressure, so as to allow the first chamber 21, the second chamber 22 and the third chamber 23 to be connected with the corresponding first connecting pipe to the sixth connecting pipe 11-16, thereby achieving the directional control of the six-way directional valve 100, thus adjusting the flowing direction of the refrigerant in the refrigerant circulation path.
Optionally, the two barrier blocks 24, the sliding block 25 and the two connecting rods 26 may be an integrally formed member, thus not only facilitating the production, processing and manufacture of the barrier block 24, the sliding block 25 and the two connecting rods 26, but also saving the production cost of the valve spool 2, in the meanwhile the connection strength among the barrier block 24, the sliding block 25 and the two connecting rods 26 may be improved to some extent, prolonging the service life of the valve 2.
