Description

[Detailed Description of the Invention] (B) Background and Problems with the Background Art Conventionally, refrigerators of this type are turned on when the door is open for convenience when delivering goods, such as at night. A lighting device is installed inside the warehouse. These lighting devices inevitably generate heat when turned on, which affects the temperature inside the refrigerator and reduces cooling efficiency, and they also have drawbacks such as the need to take insulation measures to prevent electrical leakage due to defrosting. was.

(c) The purpose of the invention is to minimize the increase in the number of objects and provide a simple structure, in which a hinge cover that is covered with the hinge protrudes forward from the upper part of the opening in an eave-like manner, and the hinge cover has a A lighting device is installed to illuminate the inside of the refrigerator when the door is opened, which illuminates the inside of the refrigerator from outside.

(E) Embodiment of the Invention Fig. 1 shows a perspective view of a refrigerator (5) of the present invention, and the interior of the main body (1) of the refrigerator (5) is separated by a partition wall (not shown) into an upper and lower freezer compartment, which will be described later. Separated into a cold storage room. (2) and (3) are a freezer compartment door and a refrigerating compartment door which are pivotally attached to the negative side so as to close the front opening of each compartment.

Further, (4) is a hinge cover, which will be described in detail later, and is disposed on the upper part of the refrigerator main body (1), and also serves as a control box with the front surface serving as an operating section (4a). As shown in the cross-sectional view of Figure 2, the refrigerator body (1) has an inner box (generally made of synthetic resin) molded in a U-shaped groove (6) formed at the front opening edge of an outer box (5) made of steel plate. It is formed by engaging and assembling the front outward facing flange (8) and foaming and filling a heat insulating material (9) between both phases (5) and (7). 00) is a freezing room, α1) is the freezer compartment door (
A gasket disposed on the inner periphery of 2), and a magnet housed inside, comes into close contact with the outer box (5) when the freezer compartment door (2) is closed, thereby airtightly closing the freezer compartment 00).

As shown in the exploded perspective view of FIG. 3, the hinge cover (4) is composed of a box-shaped main body (12) and a cover plate α3) having a cross-sectional shape. 04) is a hinge plate for pivotally supporting the freezer compartment door (2), and one end is fixed to the upper front end side of the refrigerator body (1).

The main body α2 of the hinge cover (4) is provided with a fitting hole (one hole) having the same shape as the hinge plate 04), and the main body 02 is positioned by fitting the hinge plate (I4) into this fitting hole 05). Ru.

06) is a control board consisting of a switch α exposed on the operation part (4a), a resistor CI mark, etc., and is configured to control cooling operation, defrosting operation, etc.
It is stored and fixed inside. The hinge cover (4) fits the fitting hole αQ of the main body into the hinge plate α, houses the control board αe, and closes it with the cover plate αJ. are fixed together with screws (A) etc. and assembled.

The hinge cover (4) has its front side almost closed to the freezer compartment door (
The hinge cover (4) extends forward in an eave-like manner so as to be flush with A lamp chamber (21) is formed on the bottom surface of the outer side of the main body by recessing it inward. Therefore, the lamp chamber (21) is located above the freezer compartment door (2) with the door (2) closed as shown in FIG. 2, and its opening is closed by the upper side pressure of the door (2).

Two lamps are housed in the lamp chamber (21).The two lamps are controlled by a door switch (not shown), and are configured so that they are turned on when the freezer compartment door (2) is opened and turned off when the freezer door (2) is closed. A reflecting plate 023) made of a mirror-finished metal plate or the like is attached to the ceiling wall and the inner surface on the front side of the chamber Q1), so that most of the light emitted from the lamp c2 is directed toward the freezer compartment GO) side. That is, when the freezer compartment door (2) is opened, the lamp (221
lights up, the interior of the freezer compartment 00) is brightly illuminated, and when the freezer compartment door (2) is closed, the lamp compartment (21) is closed by the door and the lamp (c) is protected from the outside. Furthermore, since the hinge cover (4) is used as a control box and the operation part (4a) is provided on the front thereof, it is easier to control the opening and closing state of the freezer compartment door (2) compared to, for example, a control part provided on the freezer compartment door (2). Since it is unrelated and does not move, it is easy to operate the switch aη, etc.

(f) Example of application of the invention In the example, the invention was applied to a so-called two-temperature type refrigerator in the two-panel world, but it may also be used in a single-door storage for freezing or refrigeration.Also, the hinge cover also serves as a control box, but it is not necessary to place it on the top of the refrigerator. There is no problem as long as it is a hinge cover that extends like an eave.

(g) Effects According to the present invention, since the lighting device is located outside the refrigerator, the heat generated during lighting does not affect the interior of the refrigerator, and there is no risk of frost formation or water intrusion, so there is no need for special insulation treatment. This also reduces workability and costs to a minimum. In addition, the light when turned on does not backlight the user compared to when a lighting device is installed inside the refrigerator, and it is easier to use because the front side is brighter and the user's hand is brighter. Since it is illuminated from the inside, it is easy to identify the stored items.

Claims (1)

[Claims] 1. A hinge that is provided on one side of the front end of the upper surface of the storage main body and rotatably supports a door that closes the opening of the storage, and a hinge cover that is covered with the hinge and is formed to protrude forward like an eave. and when the hinge cover is attached to the front part and the door body is opened.
