Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to forced combustion type gas instantaneous water heaters, gas hot air heaters, and other gas appliances.

(Prior Art) Conventionally, gas appliances of this type are known in which a forced combustion type burner unit comprising a gas burner and a combustion fan that forcibly guides combustion air to the gas burner is provided within the gas appliance body.

(Problems to be Solved by the Invention) However, in such a gas appliance, the sides of the gas appliance tend to be heated to some extent due to the operation of the burner unit inside the appliance, and thus If the device is attached to a room wall or other wall surface, there is a problem in that the wall surface is likely to overheat. In other words, it is difficult to attach the main body directly to a room wall or other wall surface on its side, and therefore it is necessary to install it on the floor, for example, away from the wall surface, making it difficult to install easily. No inconvenience involved.

(Means for Solving the Problems) The purpose of the present invention is to provide a device that does not have such inconveniences, that is, a device that can be easily installed on the ceiling or other parts of a room.
In a type in which a forced combustion type burner unit consisting of a gas burner and a combustion fan that forcibly guides combustion air to the burner unit is installed horizontally, an inner chamber and an outer chamber are separated by an intermediate partition wall inside the main body. The unit is installed in the inner chamber, and the outer chamber is connected to outside air through an air supply hole at one end and to the unit through a communication passage at the other end. The main body is provided on the outer surface of the outer chamber so as to be freely attachable to a chamber wall or other wall surface, and the outer surface is formed by a flat surface in the center and an inclined surface on the outer side. and the air supply hole is provided on the inclined surface.

(Example) Embodiments of the present invention will be explained with reference to attached drawings.

1 to 4 show an example of a gas instantaneous water heater as a gas appliance. 1 indicates the gas appliance main body, and inside the main body 1, for example, as shown in FIG. A forced combustion type burner unit 4 consisting of a gas burner 2 and a combustion fan 3 that forcibly guides combustion air to the burner unit 4 is installed horizontally, and a heat exchanger 5 is provided in front of the burner unit 4 connected to the burner unit 4. As clearly shown in Figure 3, the gas burner 2 is placed on the side thereof.
It includes a gas passage 6 connected to the gas passage 6, a gas governor 7 and an electromagnetic safety valve 8 interposed in the gas passage 6, a water passage 9 connected to the heat exchanger 5, and a water governor 10 interposed therein.

Although the above is not particularly different from the conventional one, according to the present invention, as clearly shown in FIG. and an upper outer chamber 13 in the drawing, and the burner unit 4 is placed in the inner chamber 12.
A heat exchanger unit consisting of a heat exchanger 5 and a partition wall 11a is provided on the side of the inner chamber 12.
A chamber 12a partitioned from the inner chamber 12 is provided, and each member 6, 7, 8, 9, 10, etc. is housed in the chamber 12a, and an air supply hole 14 is provided at one end of the outer chamber 13. and the air supply side 4 of the unit 4 through a communication passage 15 at the other end.
The main body 1 can be attached to the chamber wall or other wall surface a at the outer surface 16 of the outer chamber 13.

More specifically, for example, as clearly shown in FIG.
7, and a pair of mounting holes 19, 1 formed on the mounting seat plate 18, which is fixed in advance to the wall a side.
9 so that it can be attached and detached.

To be more specific, in the illustrated example, the wall surface a is the lower surface of the hanging cabinet c on the ceiling of the kitchen b, as shown in FIG. However, the present invention is not limited to this, and the main body 1 is laid down from the upward position of the outer surface 16 to the outward position as shown by the chain line in the figure, and the lower sink d in the kitchen b is placed sideways. It is also possible to attach the upper front wall to the wall surface a. In the figure, e shows a range hood on the ceiling with the exhaust pipe 23 extending from the heat exchanger 5 inside the main body 1 facing downward.

As clearly shown in FIG. 1, the above-mentioned outer surface 16 consists of a central flat surface 16a and sloped surfaces 16b on both sides thereof. 17, and a series of plural air supply holes 14 are arranged in parallel on each inclined surface 16b as an air supply surface, so that the introduction of outside air can be carried out well even in the installed state. .

Figures 5 to 7 show an example in which the gas appliance is a hot-air heater. However, the location in front of the heat exchanger 5 was made into a warm air chamber 20, and the hot air in the chamber 20 was freely blown out from the hot air outlet 22 by a hot air fan 21, but the remaining points were the same as in the previous implementation. Not particularly different from the example. The mounting condition is, for example, as shown in FIG. 6, with the outer surface 16 facing upward and the upper wall surface a.
For example, as shown in FIG. 7, it is attached to a wall a made of the outer chamber wall with the outer surface 16 facing sideways, so that warm air can be blown sideways along the wall a. It is also possible.

Figures 8 and 9 show variations thereof,
In this case, the hot air fan 2 in the above embodiment
1 and the opening direction of the hot air outlet 22 are slightly different, but the remaining points are not particularly different. For example, the mounting condition is as shown in FIG. In addition to being attached to the wall a, for example, as shown in Figure 9, it is also possible to attach it in the horizontal direction to the wall a consisting of the outer chamber wall with the outer surface 16 facing upward, so as to obtain hot air laterally. It is.

(Function) The function will be explained with reference to the embodiment shown in FIGS. 1 to 4, for example. According to the operation of the burner unit 4, water is heated in the heat exchanger 5 and the hot water is discharged. This point is not particularly different from the conventional one, but looking at the installation state, the main body 1 is equipped with the burner unit 4 in the inner chamber 12,
It is mounted on the outer surface 16 of the outer chamber 13 facing the wall surface a, and when the unit 4 is in operation, there is always a forced flow of outside air inside the outer chamber 13, which reduces the heat of the unit 4. is blocked on the outside, and furthermore, instead of an air supply hole provided on a surface perpendicular to wall surface a,
It is easy to take in air from between the wall a and the outer surface through the air supply holes 14 formed in the inclined surfaces 16b on both sides of the outer surface, and an air flow is also generated between the wall a and the outer surface. is protected from the heat generated by the unit 4 and is not damaged. In other words, the main body 1 can be attached to a room wall or other wall surface a with the outer surface 16, which is a side surface thereof, and the wall surface a remains protected from the heat of the unit 4 without causing any inconvenience. .

(Effect of the invention) According to the invention, the main body of the gas appliance can be directly attached to the chamber wall or other wall surface on the outside of the chamber, for example, without leaving a space between it and the chamber wall. Compared to the type that is placed on the floor,
For example, the space can be freely obtained in the kitchen, etc., and furthermore, when the burner unit in the inner room is operated, the outside room is always kept under a forced flow of outside air and kept at a good low temperature. The outer surface to be attached to a room wall or other wall surface is composed of a central flat surface and an inclined surface on the outside thereof, and the air supply hole is provided on the inclined surface. It is easy to take in air from between the wall and the wall, and air flows between the wall and the wall, and even if the gas appliance body is installed close to the wall, air cannot flow in from the air supply hole. It eliminates the possibility of interference, does not require any means such as making the wall surface particularly heat resistant, has a relatively simple and inexpensive structure, and makes its installation simple and easy. It has the effect of
