Description

[Detailed explanation of the idea] This idea relates to improvements in freezers.

Storage type freezers have been available in the past, but since a space for opening and closing the door is required above the freezer, space is wasted in the storage section. Another problem was that the condenser had difficulty dissipating heat.

This invention was made with attention to the above-mentioned points, and is intended to provide a top-door storage freezer that does not require wasted space and can easily dissipate heat.

In this design, a storage box and a refrigerant compressor are installed on the front and back of a base that is slidable in the front and back directions when viewed from the front of the storage box, and a storage lid is fixed to the front of the storage box. A condenser pipe is installed on the front of the lid, and an evaporator pipe is installed inside the storage box.

An embodiment of this invention will be described in detail below with reference to the drawings. In the figure, the right side is referred to as the front, and the left side is referred to as the rear.

1 is the base. The base 1 consists of longitudinal members 1a on the left and right in the front-rear direction and members (not shown) that connect the longitudinal members 1a on the left and right.

2 is a wheel supported at the bottom of the base 1;
It is configured to be able to slide back and forth.

Reference numeral 3 denotes an upper door type storage box constructed in the front part of the base 1, and 3a is the upper door of the storage box 3, and although details are not shown, the left or right side is connected to the storage box 3. . 3b is a gasket provided on the lower surface of the upper door. 3c is an evaporator pipe laid around the inner surface of the box 3. 3d is the drain pipe of box 3, which is normally closed.

4 is a refrigeration system, 4a is its refrigerant compressor,
Reference numeral 4b denotes a refrigeration system control circuit, which is attached to the back of the base 1. Further, 4c is a power source for the refrigeration device 4.

Reference numeral 5 denotes a storage lid integrally fixed to the front surface of the storage box 3. The lid 5 is made slightly larger in horizontal and vertical dimensions with respect to the front surface of the box 3, if necessary. 5a is a handle of the lid 5. 5b is a condenser pipe stretched around the front surface of the lid 5. The lid 5 is also provided with an expansion valve 5c.

And compressor 4a, condenser 5b, expansion valve 5
c, the evaporator 3c and the compressor 4a are connected through piping so that refrigerant circulates therethrough.

Next, the operation of the above embodiment will be described. It is assumed that the freezer in this embodiment is stored in a storage section S.

First, the power supply 4c is connected to the refrigeration device 4.
Then, due to a well-known action, the temperature inside the storage box 3 decreases due to heat absorption by the evaporator 3c, and is cooled.

A handle 5a is used to take in and out the stored items in the storage box 3.
By pulling forward, the storage box 3 is pulled out onto the floor SF in front of the storage section S, and the upper door 3a is opened upward (as shown by the two-dot chain line in the figure). After use, open the upper door 3a
Close the storage box 3 and push it into the storage section S.

Note that when the operation of the refrigeration device 4 is stopped, the drain pipe 3d is opened to drain water.

In addition to the above embodiments, this invention can be modified in various ways as described below.

(a) Instead of attaching the wheels 2 to the base, if a roller is supported in the storage section S, and this roller can be engaged with the stringer 1a, the wheel 2 can be mounted in front of the storage section S. There is no floor SF, so box 3 is placed in storage section S.
It can be pulled out in an overhanging state.

(b) In conjunction with the drawer of the box 3, the door 3a may be flipped upward by known means. Furthermore, the door 3a may be provided with a known means for stopping at an opening angle of about 75 to 80 degrees.

(c) It is also possible to replace each component with equivalents within the scope of the technical idea of this invention.

Since this invention is as described above, it has the following unique and remarkable effects.

(a) Since the entire freezer is made slidable in the front and back direction, it can be stored in the storage section S under the counter, sink, etc. in the kitchen room, and no extra space is required.

(b) Since the condenser pipe is installed in front of the storage compartment lid that is fixed to the front of the storage box, the exhaust heat is sufficiently diffused without any problem. Also, there is no need for dew to get on this lid.

(c) Since the storage box is placed in front of the base and the refrigeration unit is placed behind it, when the base is pulled out and placed in an overhanging state, the refrigeration unit will interfere with the action of the counterweight, causing the base to topple over. do not have.

(d) A storage compartment lid is also provided on the front of the storage box, so when this freezer is stored in storage compartment S,
The front surface of the storage section S can be completely covered, resulting in less cooling and heat loss.
