Summary of the invention
The present invention provides a kind of compact structure, the energy-saving four-way change-over valve of motor driving that cost of production is lower, to substitute existing four-way valve selector valve.
For realizing above-mentioned purpose, the present invention takes following technological scheme:
The motor driving four-way change-over valve comprises motor and the four-way change-over valve body that disposes the commutation rotor; Said motor carries out transmission to the commutation rotor; Especially, said motor is a synchronous machine; Also comprise a cam member that drives by synchronous machine, near cam member, be provided with first location switch and second location switch; The on off operating mode with second location switch is opposite all the time also to be provided with the on off operating mode that makes first location switch on the said cam member, just makes the on off operating mode of first location switch and second location switch change cam once simultaneously in 1/4 week whenever cam member turns over; Being in the location switch that has just switched to off state when heating the position with the commutation rotor is first location switch, is second location switch with another location switch; One terminal contacts of first location switch with heat the supply lines conducting; One terminal contacts of second location switch and the conducting of refrigeration supply lines; An electrode conduction of the common and synchronous machine in the other end contact of first location switch and the other end contact of second location switch, another electrode of synchronous machine and common wire conducting.
Working principle of the present invention is following:
Under the drive of synchronous machine, cam member is around self pivot axis, and its rotational angular is identical with the angular velocity of commutation rotor rotation.All the time the on off operating mode with second location switch is opposite because the cam on the cam member can make the on off operating mode of first location switch; And it's 1/4 week past for the cam member revolution; The on off operating mode of first location switch and second location switch will change once simultaneously; Because it's 1/4 week past for commutation rotor revolution; It will switch to position, refrigeration position/heat from heating position/refrigeration position; So can draw: when the commutation rotor is in when heating the position; First location switch is in off state, and second location switch is in on-state; When the commutation rotor was in the refrigeration position, first location switch was in on-state, and second location switch is in off state.Therefore, four-way change-over valve of the present invention can be according to following rule action:
1) the commutation rotor is in and heats the position, heats the supply lines energising, and the outage of refrigeration supply lines: synchronous machine does not rotate because of first location switch is in off state, and the rotor that commutates this moment still is in and heats the position;
2) the commutation rotor is in and heats the position; Heat the supply lines outage; The energising of refrigeration supply lines: synchronous machine gets electric the rotation through second location switch; Drive the commutation rotor rotation after 1/4 week; Second location switch becomes off state; Synchronous machine stops operating, and the rotor that commutates this moment is in the refrigeration position;
3) the commutation rotor is in the refrigeration position; Heat the supply lines energising; The outage of refrigeration supply lines: synchronous machine gets electric the rotation through first location switch; Drive the commutation rotor rotation after 1/4 week; First location switch becomes off state; Synchronous machine stops operating, and the rotor that commutates this moment is in and heats the position;
4) the commutation rotor is in the refrigeration position, heats the supply lines outage, and the energising of refrigeration supply lines: synchronous machine does not rotate because of second location switch is in off state, and the rotor that commutates this moment still is in the refrigeration position.
This shows that the rotor that no matter commutates is in and heats the position of still freezing, position, as long as to heating the supply lines energising, the commutation rotor finally will be in and heat the position; As long as to the energising of refrigeration supply lines, the commutation rotor finally will be in the refrigeration position.And the words of synchronous machine rotation; Also can only just stop automatically in 1/4 week of driven rotary valve core rotation at every turn; The rotor of guaranteeing to commutate drops on exactly and heats position or refrigeration position, and need not to realize the control to commutation rotor stop place through the mode that the supplied character of supply lines is done accurately to require.Therefore this product is very low to the requirement of power supply circuits, the corresponding raising of the versatility of product.
For realizing " making the on off operating mode of first location switch that the on off operating mode with second location switch is opposite all the time; just to make the on off operating mode of first location switch and second location switch change once simultaneously in 1/4 week " function, can adopt following technological scheme whenever cam member turns over:
