Embodiment Construction

[0036] An embodiment in which the present invention is applied to a refrigeration cycle of a refrigerator will be described below with reference to the accompanying drawings.

[0037] first, figure 1 The configuration of the refrigerator main body 1 and the refrigeration cycle 2 is schematically shown. in the figure 1 Among them, the inside of the refrigerator body 1 composed of the heat insulating box is partitioned into an upper refrigerating chamber 4 and a lower freezing chamber 5 by a heat insulating partition wall 3 . On the inner side of the refrigerator compartment 4, a first cooler compartment 7 is formed by a partition wall 6, and a fruit and vegetable compartment 9 is formed by a partition plate 8 at the lower part.

[0038] In the upper part and the lower part of the said partition wall 6, the blower outlet 6a and the suction inlet 6b are respectively formed. The partition plate 8 is formed with a communication port 8 a for connecting the refrigerator compartmen...

Abstract

An electric valve and a refrigerator capable of reducing the collision sound generated when the valve body position is initialized as much as possible. The control device of the electric valve applies the moving amount of the valve body (47) from the command position to the end position to the stepping motor. After the corresponding driving pulse in the forward direction, the stepper motor is applied with the driving pulse in the reverse direction corresponding to the movement amount from the terminal position to the initial position, so as to execute the position initialization action of the valve body (47). Therefore, it is possible to reduce the impact sound caused by the valve body (47) hitting the stopper (52) when the position initialization action is performed, and even if the position of the valve body (47) deviates, the valve body (47) can Reliably in the initial position.

Description

technical field [0001] The present invention relates to an electric valve for opening and closing a liquid flow passage by rotating a valve body by a motor, particularly a stepping motor, and a refrigerator for switching the refrigerant flow direction by opening and closing a refrigerant flow passage of a refrigeration cycle by using the electric valve. Background technique [0002] For example, one of the switching valves provided in the refrigerant flow passage of the refrigeration cycle of the refrigerator and used to open and close the refrigerant flow passage to switch the flow direction of the refrigerant is provided with an electric valve driven by an electric motor. The electric valve includes a valve body having a valve chamber inside, a rotatable valve body provided in the valve chamber, and an electric motor that moves the valve body along with the rotation of the rotor. In such an electric valve, the position of the valve body can be controlled by controlling the...
