Description

[Detailed explanation of the idea] (b) Industrial application fields This proposal concerns the structure of the mechanical room of a refrigerator.

(b) Prior art Utility Model Application No. 13492 (IPC, F25D23/06),
The storage in Utility Model Application Publication No. 58-13493 (IPC, F25D23/06) has a compressor,
A front-opening machine room houses a display board equipped with a condenser, a thermometer, and a defroster indicator light, a window is formed in the part facing the display board, and a ventilation hole is formed below the window. A configuration is shown that includes a cover that covers the opening, and supports such as an engaging piece, an elastic pressing piece, a receiving member, and an overhanging piece that support the cover.

According to such a configuration, since the display board is installed inside the machine room, it is long enough to read the temperature inside the refrigerator and check the presence or absence of defrost only through the window from directly in front of the machine room, which is extremely inconvenient. Not only that, the installation work and maintenance and inspection work is complicated because it involves attaching and detaching the metal plates that will become the side and back plates of the machine room, and the installation location is not the same as the upper part of the machine room. The disadvantage is that warm air stays in the upper part of the machine room, which prevents the discharge of warm air, which reduces the amount of loose air discharged from the window, reduces the air cooling effect of the compressor and condenser, and makes the inside of the refrigerator less cool. occured.

(c) Purpose of the invention The purpose of this invention is to improve the drawbacks of the above-mentioned prior art.

(d) Structure of the device It is equipped with a machine room with a front opening to house the compressor and condenser, and a knob for setting the temperature inside the refrigerator. An operation plate that traverses the front opening and divides the front opening into upper and lower halves by being fixed to both left and right end faces, and an operation plate that is fitted into a portion facing the operation plate and exposed to the outside. a window, an intake path is formed in a portion facing one of the two halves of the front opening, and an exhaust path is formed in a portion facing the other side,
A refrigerator comprising: a cover that covers the front opening; and a support that projects forward beyond the stopper to support the cover and forms a gap between the cover and the end face of the bisected front opening. .

(e) Embodiment of the invention An embodiment of the invention will be described below based on the drawings. 1 is an oblong under-counter type refrigerator used in cooking areas such as restaurants, and has two heat-insulating doors 2A on the front opening. , 2B
, a machine room 5 which is arranged on the left side of this insulation box and has a metal cover 4 on the front opening A, and a metal top table 6 which covers the top surface of this insulation box and the machine room and serves as a cooking table. It is made up of. The machine room includes the left wall 3A of the heat insulating wall, the cover,
A refrigerant compressor that is defined by the top table, a metal L-shaped side wall 7 and a metal bottom wall 8 disposed on the left side and rear side, and constitutes a refrigeration cycle together with a cooler (not shown) that cools the inside of the refrigerator. 9. A wire fin type condenser 10 is housed and installed.
Reference numeral 11 denotes an operation panel equipped with a knob 12 for setting the temperature inside the refrigerator, a thermometer 13 for displaying the temperature inside the refrigerator, and a defrost indicator light 14, and a pair of flanges 1 formed on both left and right edges thereof.
5A, 15B are superimposed on both left and right end surfaces 16A, 16B parallel to each other that define the front opening A, and are fastened with fasteners 17A, 17B such as screws, so that the front opening A can be crossed and the front The opening is divided into upper and lower halves to form upper and lower compartments A ₁ and A ₂ . An electrical equipment box 18 is fixed to the back side of the operation panel, and is arranged in the machine room 5 along with the arrangement of the operation panel 11. The cover includes a front wall 4A and an annular peripheral wall 4B.
and an annular inner wall 4C, a window 19 into which the operation plate is fitted and exposed to the outside is provided in the part of the front wall 4A facing the operation plate 11, and a window ₁₉ is provided in the part facing the upper section A1. An exhaust path 20 for discharging warm air in the machine room 5 to the outside, and an intake path 21 for sucking outside air into the machine room 5 are formed in a portion facing the lower section _A2 . Incidentally, an exhaust passage 22 is also formed in the side wall. Reference numerals 23 and 24 designate a pair of upper and lower hinges that rotatably support the cover. The upper hinge 23 is pivoted to the top table 6 so as to be spaced from the left end surface 16A, and the lower hinge 24 is spaced from the right end surface 16B. It is pivotally connected to a receiver 25 attached to this right end surface. Reference numerals 26 and 27 denote a pair of supports consisting of a strike and a catcher, and the strike support 26 is fixed at two locations above and below the right end surface 16B so as to protrude further forward than the stopper 17B to which the operation plate is fixed. Further, the catcher support 27 is fixed at two locations, upper and lower, on the left side of the inner wall 4C of the cover. 28 is a cover 4 with upper and lower hinges 23 and 24 and strike and catcher supports 26 and 27.
This is a gap formed between the inner wall 4C of the cover 4 and both left and right end surfaces 16A and 16B by supporting the cover 4 in a closed state. In addition, the upper and lower hinges 23, 2
4 also acts as a support.

According to such a configuration, the operation plate 11 has a front opening A.
Since the knob 12 for setting the internal temperature can be easily operated through the window 19 of the cover 4, the thermometer 13 and the defrost indicator light 14 can also be visually checked from an oblique direction. Also, since the flanges 15A and 15B of the operation panel 11 are attached to both the left and right end surfaces 16A and 16B of the front opening A,
The opening length of the cover 4 makes not only the installation work but also the removal work easy, and this operation panel divides the front opening A into two, creating both upper and lower compartments A ₁ and A _{2 .}
Since the exhaust passage 20 and the intake passage 21 of the cover 4 are opposed to each other, the operation plate 11 itself functions as a partition plate, thereby allowing good air intake and exhaust from the machine room 5. 27 between the left and right end surfaces 16A, 16B and the cover 4, the air intake and exhaust from the machine room 5 can be promoted, so that it is possible to prevent warm air from accumulating in the machine room 5. This gap allows the cover 4 and the stopper 17 to
Since the stoppers 17A and 17B are separated from each other, it is possible to prevent the stoppers 17A and 17B from hitting the cover 4 due to the vibration of the compressor 9, and from causing the cover 4 to resonate due to this contact.

(f) Effects of the device Since the main proposal is structured as described above, it produces the effects listed below.

Since the operation panel attached to the front opening of the machine room and the window of the cover are opposed to each other, the knob for setting the temperature inside the refrigerator can be easily operated.

Since both flanges of the operation plate are attached to the opening end face with fasteners, the operation plate can be easily attached and removed at the length at which the cover is opened.

The front opening is divided into two by the operating panel, with one side facing the exhaust path of the cover and the other facing the air intake path, so the operating panel itself acts as a partition plate, allowing good air intake and exhaust from the machine room. This prevents warm air from accumulating in the machine room.

The gap formed by the support between both end faces of the front opening and the cover can facilitate air intake and exhaust from the machine room, and it also prevents contact between the stopper and the cover and prevents vibrations of the compressor from passing through the stopper. It is possible to avoid this vibration from being transmitted to the cover and from causing the cover to resonate due to this vibration.
