Description

Refrigerator deicing device {THE ICING APPARATUS OF A REFRIGERATOR}

The present invention relates to a deicing device of a refrigerator, and in particular, when water is contained in the ice making container, the cold air generated by the evaporator flows into the inside of the ice making container container so that the water can be rapidly defrosted. The present invention relates to an ice making apparatus of a refrigerator having a structure in which a blowing direction is changed to cool an article stored in a freezer compartment with cold air.

Generally, a refrigerator is provided with a freezer compartment for maintaining a temperature below zero and a refrigerating compartment for maintaining a temperature of approximately 0 ° C to 10 ° C. The cooling operation of the refrigerator is performed by releasing heat inside the refrigerator while the refrigerant rotates sequentially, that is, the compressor, the condenser, the expansion valve, and the evaporator connected to each other by the refrigerant pipe. At this time, a refrigerator equipped with the above-mentioned cooling apparatus is recently supplied so that the freezer compartment and the refrigerating compartment of the refrigerator are cooled by separate cooling systems, but most refrigerators are cooled by one cooling system.

However, in the case of the refrigerator provided with the one cooling system described above, the refrigerator compartment is cooled by allowing cold air to flow into the refrigerator compartment side through a cold passage for communicating the freezer compartment and the refrigerator compartment with each other in a state in which an evaporator is installed on the inside of the freezer compartment.

The refrigerator is provided with a freezer compartment 3 and a refrigerating compartment 4 as a storage space for storing articles in the refrigerator cabinet 1, and the refrigerator cabinet 1 incorporates insulation to insulate the freezer compartment and the refrigerating compartment from the outside. In addition, the front doors of the freezer compartment and the refrigerator compartment are respectively equipped with a refrigerator door 2, and an evaporator 5 is installed inside the freezer compartment. The evaporator 5 is compressed by the compressor 2 installed at the lower end of the refrigerator, and the refrigerant expanded through the expansion valve absorbs heat in the freezer compartment to evaporate, thereby cooling the freezer compartment. In addition, a cold air passage 7 is formed so that air is in fluid communication between the freezer compartment and the refrigerating compartment, and a cooling fan 8 is installed in front of the evaporator for circulation of cold air in the freezer compartment. Moreover, the cold air circulated by the cooling fan by the cooling fan 8 flows into the refrigerating chamber side, so that the air in the refrigerating chamber and the refrigerating chamber is circulated in the direction of the arrow A. FIG. In addition, one side of the refrigerator compartment is provided with a temperature controller for setting the refrigerator compartment temperature to a predetermined temperature, and a temperature sensor for measuring the refrigerator compartment temperature.

On the other hand, the freezing chamber (3) is provided with an ice making container (9) to make ice by the cold air generated by the evaporator (5), the ice making container has a plurality of grooves are formed to accommodate the water is the bottom surface of the freezer shelf (3a) Mounted on the floor or placed on the bottom of the freezer compartment, whereby the received water is cooled and iced.

However, when the ice is made as described above, there is a problem that the ice making time takes a long time by constantly circulating the inside of the freezer compartment regardless of whether water is accommodated in the ice making container.

Therefore, the present invention is devised to solve the problems as described above, when water is contained in the ice making container, the cold air of the freezer compartment is concentrated on the ice making container side to shorten the ice making time, and after the ice making is completed, the cold air is stored in the freezing compartment. It is an object of the present invention to provide an ice making apparatus for a refrigerator having a configuration for dispensing into another article.

In order to achieve the object as described above, the ice making apparatus of the refrigerator according to the present invention is formed by receiving an ice making container in communication with at least one cold air outlet of the plurality of cold air outlets formed left and right spaced apart from the rear upper inner wall of the freezer compartment. Cold air blocking plate mounted on the cold air discharge port to block the inflow, expands when air is injected inside, shrinks by elastic force when air leaks, bellows equipped with the cold air blocking plate on one side, the bellows to inject air into the bellows And an air injector connected in fluid communication with a temperature sensor, and a temperature sensor embedded in the ice-making container container to contact a metal piece embedded in the ice-making container to measure the temperature of the ice-making container.

Hereinafter, with reference to the drawings will be described in more detail.

Figure 2 schematically shows an ice making apparatus installed in the freezer compartment of the refrigerator according to the present invention, the freezer compartment is installed so that the evaporator 50 is installed behind the inner upper wall 40 and the cold air generated by the evaporator is discharged into the freezer compartment. The cooling fan 60 is mounted to the front of the evaporator. In addition, a pair of cold air discharge ports 41 are formed on the inner wall so as to be spaced apart from side to side so that the cold air discharged by the cooling fan is not blocked by the inner wall, and the ice making container 10 is accommodated in front of the discharge port. An ice making container holder 20 is mounted. In addition, a plurality of cold air vents 42 wrapped with a wire mesh in consideration of aesthetics are provided at an upper portion of the cold air discharge ports so that cold air flows smoothly into the article placed on the upper surface of the freezer compartment 30.

The ice tray 20 is formed inside the guide piece 21 to face each other so that the ice tray 10 is slidably mounted forward and backward, and is preferably installed on the bottom surface of the freezer shelf 30. In addition, the ice making container 20 is in communication with at least one cold air discharge port 41 is introduced into the cold air discharged by the cooling fan, the cold air discharge port 41 is a discharge opening and closing device to be described later It is selectively opened and closed by the provided cold air blocking plate 80 (FIG. 3A). Furthermore, a groove 22 is formed at the bottom of the ice making container container and is equipped with a temperature sensor for measuring the temperature of the water contained in the ice making container.

3A and 3B illustrate an operation of selectively opening and closing the cold air discharge port by the discharge opening and closing device. Referring to FIGS. 2 and 3A and 3B, the outlet opening / closing device including the cold air blocking plate is mounted, and the cold air blocking plate 30 is mounted on the rear side of the inner upper wall 40, and the cold air blocking plate selectively selects the cold air discharge port. The cold air blocking plate 80 is operated left and right by the corrugated pipe or the bellows 100 to open and close the air. The bellows is connected to the air injector 110, and is expanded by the air injected by the air injector, thereby preventing the cold air blocking plate. 80 will be pushed to one side.

At this time, the air injector is electrically connected to the temperature sensor 70 mounted in the ice making container holder, injecting air into the bellows if the water temperature of the ice making vessel sensed by the temperature sensor is above the first set temperature. If the temperature is lower than the second set temperature, the air injected into the bellows is leaked to shrink the bellows. In addition, the bellows is usually contracted by its elastic force when air is not injected, so that the cold air blocking plate 80 returns to its original position.

On the other hand, the first set temperature is preferably determined by the freezing point of water, the second set temperature is set to be the same as the freezer compartment internal temperature, preferably from minus 5 ℃ to minus 15 ℃. Furthermore, the ice making vessel is formed of plastic material to facilitate the extraction of the ice after the contained water has been defrosted, so that the metal piece having a better thermal conductivity in the ice making vessel is prevented from deteriorating the temperature sensing of the water by the temperature sensor, most preferably. It is preferable that the metal piece of stainless steel is inserted.
