Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention relates to a gas burner fixing structure for an absorption refrigerator,
More specifically, as an absorption refrigerator cycle, a generator,
The present invention relates to a gas burner fixing structure for an absorption refrigerator that includes a rectifier, a condenser, an evaporator that cools a refrigerating chamber, an absorber, and a liquid receiving tank, and uses at least gas combustion as a heating source of a generator.

(B) Problems to be solved by the conventional technology and device The conventional gas burner fixing structure of this type of absorption refrigerator is
For example, as shown in FIG. 5, a base plate 1a attached to the main body of the absorption refrigerator, and a vertical plate 5a formed by bending the base plate 1a on the base plate substantially vertically and integrally forming the nozzle part 3a of the gas supply pipe 2a with a nut 4a. Similarly, a combustion box 6a integrally formed in a box shape on the substrate 1a so as to face the vertical plate 5a,
It has a tubular shape, one opening end of which is fitted and supported by the nut 4a of the nozzle portion 3a, the body portion penetrates the through hole 7a and is pressed downward by the burner holder 10a, and is fixed to the substrate 1a as a whole. There is. A gas burner 8a and a combustion cylinder that extends upward from the ceiling wall of the combustion box 6a and heats the generator of the absorption refrigerator.
Mainly consists of 11a and.

Thus, the gas burner 8a is a small part and requires the burner retainer 10a and the screw 9a which are not always mounted well, and the fixation thereof is not necessarily strong in the longitudinal direction (horizontal direction) of the gas burner 8a. was there. Particularly with regard to the latter problem, the horizontal position of the gas burner 8a is likely to change due to variations in the dimensions of each component, and the nozzle portion 3a, the combustion port 12a, and the combustion cylinder 1
There is a risk that the desired combustion gas cannot be sent to the generator due to the relationship of 1a being deviated.

(C) Means for Solving the Problem and Its Action The present invention is directed to a substrate attached to an absorption refrigerator body, and a vertical plate integrally formed on the substrate substantially vertically and having a nozzle portion of a gas supply pipe fixed thereto. Similarly, a combustion box integrally formed in a box shape on the substrate so as to face the vertical plate, a tubular gas burner that penetrates the opposite side wall of the combustion box from the nozzle portion and reaches the inside of the combustion box, and a combustion box And a combustion cylinder for heating the generator of the absorption refrigerator, the vertical plate having a slit, and the gas burner is an opening of a gas burner bent through the slit at the opening end on the nozzle portion side. It is a gas burner fixing structure of an absorption refrigerator having an end fixing protruding piece.

That is, the present invention forms a slit in the vertical plate, while forming a protruding piece that can be bent and fixed by the slit at the open end of the gas burner, thereby eliminating the need for a gas burner holder or separate parts such as screws. ,
You can easily assemble each part, and, of the gas burner,
It is intended to prevent the positional displacement in the horizontal direction with respect to other parts.

(D) Embodiments The present invention will be described in detail based on the embodiments shown in the drawings. The invention is not limited to this.

First, in FIGS. 1 and 2, a substrate 1 attached to an absorption refrigerator main body and a substrate 1 integrally formed substantially vertically on the substrate,
A vertical plate (frame) 5 to which the nozzle portion 3 of the gas supply pipe 2 is fixed, a combustion box 6 integrally formed on the substrate 1 so as to face the vertical plate 5 in a box shape, and cylindrical,
A gas burner 8 extending from the nozzle part 3 through the opposite side wall of the combustion box 6 to reach the inside of the combustion box 6 and a gas burner extending upward from the ceiling wall of the combustion box 6 to generate an absorption refrigerator (17, see FIG. 3). It mainly consists of a combustion cylinder 11 for heating the. Reference numeral 4 is a nut for fixing the nozzle portion 3 to the vertical plate 5, 7 is a through hole formed in the combustion box 6, 12 is a combustion port of the gas burner 8, and 16 is a screw for attaching the combustion cylinder 11.

Reference numeral 14 is a slit formed in the vertical plate, and 15 is a projecting piece (claw) for fixing the opening end of the gas burner formed at the opening end of the gas burner 8 on the nozzle portion 3 side, which is bent through the slit and thereby the gas burner is bent. 8 is fixed to the combustion box 6.

Thus, the work of fixing the gas burner 8 to the combustion box 6 is simply performed by passing the projecting piece 15 through the slit 14 and bending, and there is no work of attaching parts by screws, and the work is extremely simple. In particular, horizontal positioning of the gas burner 8 is possible by simply bringing the open end of the gas burner 8 into contact with the vertical piece 5 and bending the protruding piece 15.

The absorption type refrigerator, as shown in FIGS. 3 and 4, has an absorption refrigeration cycle as a generator 17, a rectifier 18, a condenser 19 and an evaporator (not shown) for cooling a refrigerating chamber (not shown). (Not shown), an absorber 20, and a liquid receiving tank 21.
As a heat source of the above, any one of a heater for AC 100V, a heater for DC 12V, and gas combustion of the cassette cylinder 22 can be selected and used. Here, 23 is a cabinet of an absorption refrigerator main body, 24 is a gas supply pipe 2 provided in parallel with the gas supply pipe 2, and 25 is a back cover of the cabinet 23.

(E) Effect of the device According to this device, a slit is formed in the vertical plate, while
By forming a protruding piece that can be bent and fixed with the slit at the open end of the gas burner, it is possible to easily assemble each part without the need for separate parts such as a burner presser or a screw. It is possible to prevent horizontal displacement with respect to other parts.
