Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator which can be electrically connected to an operation unit provided on a refrigerator door and a control unit provided on the refrigerator body side without using electric wires. .

[0002]

2. Description of the Related Art In recent years, it has become common practice to operate the refrigerator without opening the refrigerator by providing an operating portion for setting the temperature of the refrigerator on a part of the door. Regarding the connection between these operation parts and the control board provided on the refrigerator main body side, the fulcrum part for opening and closing the door is hollow, and the electric wire is pierced through the fulcrum part for electrical connection. Came.

An example of a refrigerator disclosed by Japanese Utility Model Publication No. 52-18769 equipped with a hollow hinge pin for supporting a door will be described below with reference to the drawings.

Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 2, an inner box 3, and a foamed heat insulating material 4 filled between the two boxes 2. Reference numeral 5 is a door, and 6 is a lower hinge pin located below the door 5, which is fixed to the outer box 2 with a screw 6a. A hollow hinge pin 7 is formed integrally with the upper end of the door 5. Reference numeral 8 is a door support plate that rotatably supports the hollow hinge pin, and is fixed to the outer box 2 by screws 8a. 9
Is attached to the door 5 integrally with the operating portion.

Reference numeral 10 is a control board for controlling the refrigerator, 11 is a refrigerator main body side electric wire, 12 is a door side electric wire, 13 is a relay electric connector, and the electric wires 11 and 12 are electrically the relay electric connector. It is connected. Reference numeral 14 is a decorative cover that protects the relay electrical connector portion, and is fixed to the door support plate 8 with a nail or the like. In the refrigerator configured as described above, the signal operated by the operation unit 9 is sent to the control board 10 through the electric wires 11 and 12 to control the refrigerator.

[0006]

However, in the above-mentioned configuration, in order to transmit and receive the electric signal from the control board 10, it is necessary to wire the electric wires 11 and 12 to the operation section 9, and the door side electric wire 12 is required. After assembling the refrigerator body 1 and the door 5, the electric wire 11 on the refrigerator body side is connected to the electric connector 13 for relay.
Must be connected by.

Furthermore, since the door-side electric wire 12 is wired so as to penetrate through the inside of the hollow hinge pin 7, the upper end surface of the hollow hinge pin 7 is always in contact with the door 5 when the door 5 is opened and closed to cover the electric wire. There was a problem of damaging the wire and breaking the wire.

Further, since the electric wires 11 and 12 are embedded in the foamed heat insulating material and pass therethrough, there is a problem that the flowability of the foamed heat insulating material at the time of foaming is alienated to form a cavity, and the heat insulating performance is significantly deteriorated.

In view of the above-mentioned drawbacks of the prior art, the present invention provides a door support plate that supports one end of an openable door with a signal transmitting / receiving unit, and an operating unit of the openable door with a signal transmitting / receiving unit. The electric wire built in the side is abolished and the above-mentioned subject is solved.

[0010]

A refrigerator of the present invention includes a main body, a door attached to the main body by a door support, a control unit attached to the main body side, and the support connected to the control unit. A first signal transmitting / receiving unit attached to the body,
The second signal transmission / reception unit is attached to the door and exchanges signals with the first signal transmission / reception unit in a contactless manner, and an operation unit connected to the second signal transmission / reception unit.

Further, the main body, the door attached to the main body by a door support, the control section attached to the main body side, and the first signal transmitting / receiving section connected to the control section and attached to the inner surface of the main body. And a second signal transmission / reception unit attached to the door for exchanging signals via a reflector attached to the door support, and an operation unit connected to the second signal transmission / reception unit. is there.

[0012]

Therefore, the door supporting plate attached to the upper surface of the main body, the first signal transmitting / receiving unit attached to one end of the door supporting plate, and the second signal transmitting / receiving unit facing the first signal transmitting / receiving unit are connected to the door. Signals are transmitted and received to and from the side operation unit.

Further, transmission / reception is performed by changing the route of the signal between the first signal transmitting / receiving section located at the rear of the upper surface of the main body and the second signal transmitting / receiving section formed integrally with the door side operation section. Be seen.

Reference numeral 24 denotes a reflector, which is opposed to the second signal transmitting / receiving unit 17 and forms an angle with the decorative cover 14. Reference numeral 14a is a notch portion for preventing the first signal transmitting / receiving portion opened to the rear of the decorative cover from being obstructed.

[0019]

As described above, according to the present invention, in a refrigerator having a main body and a door that can be opened and closed from the main body, a door support plate attached to the upper surface of the main body is provided so that the control unit and the operation unit can be operated in a non-contact manner. Since the first signal transmitting / receiving unit attached to one end and the second signal transmitting / receiving unit facing the first signal transmitting / receiving unit are provided in the door-side operation unit, the refrigerator main body and the openable / closable door are provided. Electricity makes it possible to abolish the latitude line itself, and troubles such as disconnection of the wiring cord due to opening and closing of the door can be eliminated, and an inexpensive and highly reliable signal transmission means can be obtained.

In addition, the first signal transmitting / receiving unit is provided in the control unit located on the rear of the upper surface of the main body of the refrigerator, and the angle facing the operating unit is set so that the signal transmission with the second transmitting / receiving unit is performed efficiently and reliably. Since the front end part of the door support plate is integrally formed with the opposing reflectors, the control board on the refrigerator body side and the wiring cord connecting the first signal transmitting / receiving part can be eliminated, and the number of parts can be further reduced. Since it can be reduced, there is an effect of obtaining an inexpensive signal transmission means.

Furthermore, since the door side wiring cord and the main body side wiring cord do not exist, the flowability of the foamed heat insulating material, which is a heat insulating material, is not hindered during the foaming process, and the heat insulating performance can always be obtained.
