DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of a refrigerator showing an embodiment of the present invention. FIG. 2 is a sectional view of the automatic ice making machine of the present invention housed in a freezing compartment. FIG. 3 is an exploded perspective view showing an electric pump between the water supply tank and the ice tray of the present invention.
FIG. 4 is a perspective view showing the automatic ice making machine of the present invention.

Reference numeral 1 denotes a refrigerator. This refrigerator has an outer box 2 made of a steel plate which is opened forward, an inner box 3 made of a hard synthetic resin which is forwardly opened and is incorporated in the outer box with a space therebetween. A main body 5 is composed of a polyurethane foam insulation material 4 filled between the boxes 2 and 3 by an in-situ foaming method. The inner box 3 is divided into upper and lower parts by a partition wall 6, a refrigerating chamber 7 is formed on the upper side, and a freezing chamber 8 is formed in two stages on the lower side. The front opening of the refrigerator compartment 7 is a door 9 and the front opening of the freezer compartment 8 is a drawer door 1.
At 0, it is openably closed.

A U-shaped frame 11 having one end fixed to the rear surface is fixed to the drawer door 10. This frame is the main body 5
It is slidably fitted in the front-rear direction on a fixed rail 12 with a roller provided in the lower container 13 and is internally held by a lower container 13 which is divided into two left and right parts. Above this lower container is an upper container 14
And an automatic ice machine 15 are arranged.

At the back of the freezer compartment 8, there is provided a cooler compartment 19 which is partitioned by a partition wall 16 and accommodates a cooler 17 and a blower 18 arranged above the cooler. The partition wall 16 is provided with a slit 18A in front of the blower 18 in the freezer compartment 8 for blowing out the cool air cooled by the cooler 17.

The automatic ice maker 15 has a mounting frame 20 having an opening at the bottom, and an ice tray 2 housed in this frame.
1 and a drive device 22 for rotating the ice tray. An ice tray 23 is formed on one side of the lower container 13 arranged below the ice tray 21.

Reference numeral 24 is a water supply tank fixed in the refrigerating compartment 7, and the water supply tank is connected to the piping 2 via an electric pump 25.
6 are connected. This pipe has a tip opposite to the water supply tank 24 penetrating the partition wall 6 and opening above the ice tray 21.

27 is a drive unit 22 for rotating the ice tray 21.
A control device for controlling the water supply tank 24
After confirming that the water poured into the ice tray 21 has frozen, the driving device 22 is rotated to separate the ice from the ice tray 21 and store the ice tray 21 in the ice tray 23. It is controlled to return to the position.

28 is a door switch provided in the freezer compartment 8
This door switch causes the control device 27 to stop the operation of the drive device 22 when the drawer door 10 is opened.

In the ice making device of the refrigerator thus constructed, the water in the water supply tank 24 is poured into the ice tray 21 by the pump 25 through the pipe 26. Then, the water poured into the ice tray 21 blows cold air cooled by the cooler 17 into the freezer compartment 8 by the blower 18 and is frozen. The ice frozen in the ice tray 21 is stored in the ice tray 23 after the ice tray is twisted by the drive unit 22 to separate the ice.
The ice tray 21 for which the ice removing work has been completed is returned to the original position by the drive device 22 again. After that, this operation is repeated to automatically make ice.

The control device 27 can interlock with the door switch 28 of the drawer door 10 in which the ice tray 23 is arranged, so that the operation of the drive device 22 can be stopped when the drawer door is opened, and the ice tray 21 is opened. I try not to rotate. Further, since the control device 27 stops the rotation of the ice tray 21 even if the ice tray 23 is pulled out while the ice tray 21 is being rotated by the drive device 22, the ice in the ice tray 21 is frozen in the freezer compartment 8. It can be prevented from scattering inside,
It is designed to prevent your hands or fingers from being caught.

The control device 27 stops the drawer door 10 when it is opened, and restarts the drive device 22 from the stopped state when the door 10 is closed.

[0019]

According to the first aspect of the present invention, there is provided a main body which opens a front surface to form a refrigerating chamber and a freezing chamber up and down, and a door which closes the opening of the main body. An ice tray to be iced, a water tank is installed in the refrigerator room,
In the ice making device of the refrigerator in which the water supply tank and the ice tray are connected by a pipe with a pump, and the ice tray is provided under the ice tray, the rotation of the drive mechanism is stopped when the door is opened. Since it is equipped with a control device, it is possible to prevent accidents where a hand or finger is caught.

According to the second aspect of the present invention, the ice tray to be iced by the drive mechanism is installed in the freezing compartment, the water supply tank is installed in the refrigerating compartment, and the water supply tank and the ice tray are connected by the pipe with the pump. At the same time, in the ice making device of the refrigerator in which the ice tray is provided below the ice tray in the drawer, the controller is provided to stop the rotation of the drive mechanism while the drawer is being pulled out. Even if the ice tray is pulled out while the ice tray is being operated by the drive unit, the ice in the ice tray can be prevented from being scattered into the freezing compartment.
