DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice making device for discharging ice produced in an upper space for equipment to an ice storage space below.

[0002]

2. Description of the Related Art As shown in FIG.
In some cases, a drainage tray 2 is disposed between an upper appliance space A and a lower ice storage space B. The equipment to be arranged in the upper equipment space A includes a number of small ice making chambers 3 opening downward.
a, an ice tray 3 formed with a, a water tray set 4 openably and closably provided below the ice tray 3, an actuator 5 for opening and closing the water tray set 4, and a refrigerant for cooling the ice tray 3. There is a refrigerant piping device 6 for circulation. The water tray set 4 is provided so as to swing between an upper closed position C and an open position D that tilts downward, and stops at the upper closed position C when making ice, and the ice making chambers 3a The ice making water is supplied to the ice making chamber, and stops at the open position D that tilts downward during deicing so as not to hinder the release of ice generated in the ice making chamber 3a.

In the ice making, water is sprayed from a set of water trays 4 toward each of the ice making chambers 3a of the ice tray 3 cooled by the refrigerant piping device 6, and an ice layer is gradually formed in each of the ice making chambers 3a. Generates ice blocks. When deicing, the water tray set 4 is tilted by operating the actuator 5, and a plurality of ice blocks E separated from each ice making chamber 3a are discharged to the ice storage space B via the communication portion F without the drain tray 2. At the same time, the ice making residual water released from the tilting water tray set 4 is collected by the drain tray 2 and discharged to the outside.

[0004]

By the way, the drainage dish 2
Is designed to function as a tray for remaining ice making water and washing water from the water tray set 4, but to catch rust and water drops falling from the pipe 6a of the actuator 5 and / or the refrigerant piping device 6 or the accumulator 6a. It is not possible. Therefore, in the conventional ice making device 1, rust and water drops may fall on the ice blocks E in the ice storage space B from the actuator 5 and the refrigerant piping device 6, which may be unsanitary.

Further, in the conventional ice making device 1, since the communication portion F without the drain tray 2 is largely open, the communication between the ice tray 3 and the water tray set 4 which is tilted and opened at the time of deicing is established. It was possible to easily reach through the part F, which was very dangerous.

In order to solve the above problems, the present invention provides an ice making device that does not allow rust or water drops to fall on ice in an ice storage space, and an ice making device that does not allow a hand to reach the upper appliance space. The purpose is to provide.

[0007]

In order to prevent rust and water droplets from falling on ice in the ice storage space, the means adopted by the present invention is an actuator for opening and closing the water tray set and a coolant for the refrigerant. In an ice making device in which a drain tray is arranged between an upper appliance space provided with a piping device and a lower ice storage space, the drain tray is discharged from the appliance space to the ice storage space with deicing. An ice discharge port for allowing ice to pass through, and a receiving portion extending from the peripheral portion of the ice discharging port to the surroundings is provided, so that a falling object from the actuator or the refrigerant piping device is received by the receiving portion. An ice making device characterized in that: According to the present invention, ice is discharged through the ice discharge port of the drainage dish into the ice storage space with deicing, and rust and water droplets falling from the actuator or the refrigerant piping device are collected at the receiving portion of the drainage dish. Because it is received, it does not fall into the ice storage space.

According to a second aspect of the present invention, in order to prevent a hand from being inserted into an upper appliance space, an ice extraction door facing the ice storage space is provided, and the drain tray is provided. 2. The ice making device according to claim 1, wherein the size of the ice making device is such that a hand cannot be inserted from the ice storage space to the appliance space. In the present invention, even if an attempt is made to reach into the appliance space from the ice storage space, the hand is blocked by the drainage dish, and the hand cannot be extended into the appliance space.
