Due to this, there was a problem that the ice production completion control device no longer controls the ice production stop during the operation of the ice making machine, and the ice overflows from the ice storage. The present invention has been made to address the above-mentioned problems, and its purpose is to keep the ice storage completion detecting device from entering the ice storage during the assembly of the ice making machine so that the ice making operation can be performed during operation of the ice making machine. It is to provide an automatic ice maker that prevents ice from overflowing from the ice storage.

[0004]

[Means for Solving the Problems] In order to achieve the above-mentioned object, a structural feature of the present invention is that an ice-making unit unit including an ice-making device and an electric control device is loaded on an ice storage. The electric control device controls the operation of the ice making device to automatically and successively produce ice, and the ice making device drops the produced ice and stores it in the ice storage unit. Before being combined with the ice storage, it is housed in the ice-making unit, and after the combination, it is assembled so as to enter the ice storage, and it is detected that the ice storage is filled with ice, and the electric control device is activated. In an automatic ice machine equipped with an ice storage completion detecting device to be stopped, the ice storage completion detecting device is in the first state in a state where the ice storage completion detecting device is not assembled and is connected to the electric control device.

 An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 schematically show a stack-on type automatic ice making machine according to the present invention in a sectional view.

This automatic ice making machine is provided with a rectangular parallelepiped ice storage 10 that is open at the top, and an ice making unit 20 that is loaded on the ice storage 10. The ice making unit 20 is formed in a box shape by a top plate 20a, side plates 20b and 20c, a bottom plate 20d, and a back plate and a front panel (not shown), and the inside thereof is divided into an ice making chamber R1 and a control chamber R2 by a partition plate 20e. It is partitioned. An ice making device 21 including an ice making mechanism and a freezing circuit is housed in the ice making chamber R1, and the ice produced by the ice making device 21 is guided downward along the guide plate 22 and is provided on the bottom plate 20d. It is designed to drop into the ice storage 10 through the open hole 20f. In the control room R2, an electric control device 23 for controlling operations such as a water supply process, an ice making process, a deicing process and a drainage process of the ice making device 21 and an ice storage completion detecting device are provided.

The ice storage completion detecting device includes a hook member 31 and an ice storage completion sensor 32. As shown in FIGS. 1 to 4, the hook member 31 has a vertical plate 31a and a horizontal plate 31b integrally formed in a substantially L shape, and a protruding piece 31c protruding downward from the horizontal plate 31b. A long hole 31a1 is formed in the upper center of the vertical plate 31a, and a hook 33 is fixed to the control chamber R2 side of the partition plate 20e. The hook 31 is attached to the ice making machine before assembly. It is adapted to be hooked on the hook 33 through the long hole 31a1. The mounting height of the latch 33 from the bottom plate 20d is set to be larger than the entire length of the latch member 31 in the up-down direction, and the entire latch member 31 is completely housed in the control chamber R2 by the latch. It is supposed to be done. A long hole 20d1 is formed in the bottom plate 20d so that the protruding piece 31c can enter the ice storage box 10. In the intruding state, the horizontal plate 31b functions as a stopper by contacting the bottom plate 20d.

The ice storage completion sensor 32 is composed of a temperature sensing portion 32 a fixed to the lower end portion of the protruding piece 31 c of the locking member 31 and a pressure switch 32 b provided in the electric control device 23. The temperature sensing part 32a is composed of a copper tube filled with gas, and the pressure inside the copper tube is guided to the outside via a flexible thin tube 32c. The thin tube 32c is guided upward in a state of being loosened through a small hole 31b1 provided in the horizontal plate 31b of the hooking member 31 and penetrates into the electric control device 23, and a pressure switch 32b is connected to the end thereof. Has been done. The pressure switch 32b is normally on, and when the temperature of the temperature sensing part 32a drops, the gas pressure in the copper tube drops and turns off.

A holding plate 31d is integrally provided on a side portion of the latch member 31 at a position slightly higher than the horizontal plate 31b. On the other hand, the microswitch 41 is fixed on the bottom plate 20d in the lateral direction of the long hole 20d1. A lever 42 is attached to the micro switch 41. The switch 41 is normally in an off state, and is turned on when the latch member 31 is moved downward and the lever 42 is pressed by the pressing plate 31d. It is a thing. The micro switch 41 is connected to the electric control device 23 via conductors 43a and 43b.

The wiring relationship between the pressure switch 32b and the micro switch 41 of the ice storage completion sensor 32 arranged as described above will be described. As shown in FIG. 5, the pressure switch 32b and the micro switch 41 are connected in series between an electric control device 23 that controls the ice making device 21 and a power supply 44 that supplies electric power to the electric control device 23. There is. Therefore, only when both the pressure switch 32b and the micro switch 41 are in the ON state, electric power is supplied from the power source 44 to the electric control device 23, and the device 23 becomes operable for the first time to control the operation of the ice making device 21. To do.

Next, the operation of the embodiment configured as described above will be described. First, during transportation of the ice making machine, the ice storage 10 and the ice making unit 20 are separately packaged and shipped, and at the same time, the hooking member 31 is hooked by using the long hole 31a1 provided in the vertical plate 31a. It is shipped in a state of being hooked on the stopper 33, that is, in a state where the ice storage completion detecting device is accommodated in the ice making unit section 20. Then, the packaging is unpacked at the place where the ice making machine is installed, the ice making unit 20 is loaded on the ice storage 10, and the ice storage 10 and the ice making unit 20 are united. In this state, the front panel is opened, the hooking member 31 is removed from the hooking tool 33, and the protruding piece 31c is made to enter the ice storage compartment 10 through the long hole 20d1, and the horizontal plate 31b thereof is fixed to the ice making unit. The ice storage completion detecting device is attached to the ice storage 10 by bringing it into contact with the bottom plate 20d of the portion 20 and adhering the both plates 31b, 20d with an adhesive or a screw. If the hook member 31 does not rattle due to its own weight, it is not necessary to connect the plates 31b and 20d with an adhesive or a screw. With the assembling of the ice storage completion detecting device, the pressing plate 31d presses the lever 42, so that the micro switch 41 is turned on.

When the power source 44 is connected to the electric control device 23 in such a state, the pressure switch 32b is initially set to the ON state and the micro switch 41 is also set to the ON state. Electric power from the power supply 45 is supplied to the electric control device 23. As a result, the electric control device 23 starts its operation and controls the operations of the ice making device 21, such as the water supply operation, the ice making operation, the deicing operation, and the drainage operation, so that the ice making device 21 automatically creates ice one after another. To manufacture. Then, the manufactured ice moves downward along the guide plate 22 and falls into the ice storage 10 through the opening hole 20f. When the ice storage 10 is filled with ice due to this drop, the temperature sensing part 32a of the ice storage completion sensor 32 becomes buried in the ice, and the gas in the copper pipe forming the temperature sensing part 32a is filled. Is cooled and the pressure drops. This pressure sets the pressure switch 32b to the off state via the thin tube 32c, so that the electric power from the power source 45 is not supplied to the electric control device 23 and the operation of the device 23 is stopped, and the ice making device 21 makes ice. Since the operation is also stopped, it is possible to avoid the situation where the produced ice overflows from the ice storage 10. In this state, when the ice in the ice storage 10 is removed and the pressure switch 32b is turned on again, the electric control device 23 controls the ice making device 21 to restart the ice making by the device 21. ..

On the other hand, at the time of assembling the ice making machine, the protruding piece 31c of the hooking member 31 and the temperature sensing portion 32a of the ice storage completion sensor 32 are kept in the ice storage until the hooking member 31 is hooked on the hooking member 33. If the user forgets to put the ice storage completion detecting device into the refrigerator 10 and assembles the ice storage completion detecting device, the micro switch 41 is kept in the off state, so that the lead wires 43a and 43b are released and the electric power from the power supply 44 is supplied to the electric control device 23. Not supplied to. As a result, if the ice maker is assembled in an imperfect state, the electric control device 23 will not operate and the operation of the ice maker 21 will also be held in a stopped state, so that the installer will move the ice storage completion detecting device to the normal position. You can easily check that the installation of the ice machine is not completed, and the ice machine will always operate in normal condition.
