Description

[Detailed description of the invention] Industrial application field This invention combines a water heater with a gas stove, and is particularly effective in applying exhaust gas to the kitchen of a high-rise apartment complex. Regarding structure.

BACKGROUND TECHNOLOGY In conventional kitchens, water heaters are independent from other gas appliances, and are generally installed near the sink, for example, at the top of the front of the sink. The container and the gas stove were located vertically apart, so there was no need to consider the possibility that boiling liquid would leak into the combustion part of the water heater.

Problems that the invention aims to solve However, when a water heater is integrated with a gas stove, the water heater is installed at a low location such as above the gas stove in a kitchen set, and the boiling liquid etc. There is a risk that it may enter the combustion part of the device. Therefore, this idea was developed to improve safety, durability, etc. of a gas table combined water heater by cooling the combustion exhaust from the water heater to a safe temperature and discharging it, and by guiding all boiled water etc. to the outside of the water heater. The purpose is to provide an exhaust structure.

Means to solve the problem In this invention, the water heater B is placed on the back of the gas stove A.
In a gas table composite water heater integrally provided with a combustion section C, an exhaust box 3 that covers the heat exchanger 2 of the combustion section C is provided on the upper part of an outer shell 1 that surrounds the combustion section C of the water heater B. A convex portion 4 is provided on the rear surface of the exhaust box 3 so as to protrude rearward from above the heat exchanger 2. An exhaust port 5 is provided at the top of the convex portion 4, and an intake port 6 is provided at the bottom of the convex portion 4.
The aim is to solve the above-mentioned problems by adopting essential technical means.

Function Since this device has the above configuration, the combustion exhaust discharged from the heat exchanger 2 of the combustion section C of the water heater B mixes with the air rising between the combustion section C and the outer shell 1 in the exhaust box 3. At the same time, the convex part 4 mixes with the air outside the device from the intake port 6 and is further cooled, and the exhaust gas cooled to a safe temperature flows into the convex part 4.
is discharged outside the device from the exhaust port 5. In addition, if the boiling liquid etc. caused by boiling over the boiling food on the gas table A spills onto the exhaust box 3 and enters the convex part 4 from the exhaust port 5, the boiling liquid etc. is discharged to the outside from the intake port 6 directly below and goes to the combustion part C. can prevent the infiltration of The boiling liquid and the like spilled onto the top plate 3a of the exhaust box 3 flows forward and toward the top plate side of the gas stove A. In addition, in this operation of preventing the infiltration of boiling liquid, etc., the effect becomes more pronounced if the top plate 3a of the exhaust box 3 is tilted forward and a damming protrusion 7 is provided at the lower inner end of the convex portion 4.

Embodiment An embodiment of this invention will be described below based on the drawings.

In the drawing, A is a gas stove, which is equipped with a grill 10 between two stoves 8 and 9, and has push buttons 12 and 1 for flashing operation on its front operation panel 11.
3, 14 and capacity adjustment slide knobs 15, 1
6 and 17 are provided. B is a gas water heater, and its combustion part C is integrally provided on the rear surface of the gas table A to constitute a gas table composite water heater. The combustion section C is equipped with a heat exchanger 2 at the upper end of the inner shell 18, a main gas burner 19 is installed at the lower part of the inner shell 18, and the heat exchanger 2 is heated by the main gas burner 19. The structure is such that the water flowing through 2 is heated to raise its temperature and hot water is released. Also, 1
is an outer shell that surrounds the combustion section C of the gas water heater B, and an exhaust box 3 is integrally provided on the upper part of the shell so as to cover the heat exchanger 2 of the combustion section C, and the top plate 3a of the exhaust box 3 is is tilted forward, that is, toward the gas table A side. Reference numeral 4 denotes a convex portion provided on the rear surface of the exhaust box 3, which projects rearward from above the heat exchanger 2 and is provided integrally with the exhaust box 3. Reference numeral 5 indicates an exhaust port formed in the upper part of the convex part 4, and numeral 6 indicates an intake port formed in the lower part of the protrusion 4, which are vertically aligned with the exhaust port 5.
Reference numeral 7 denotes a damming projection protruding from the lower inner end of the convex portion 4.

In addition, in the figure, 20 is a push button for blinking operation of the gas water heater B, which is provided on the front operation panel 11 of the gas table A. 21 is the combustion section C of the gas water heater B
The secondary air intake port 22 is a ventilation gap formed between the combustion section C of the gas water heater B and the outer shell 1.
Reference numeral 23 denotes a rectifying guide plate provided on the convex portion 4 side of the exhaust box 3 so as to be oriented toward the exhaust port 5 . moreover,
D is the gas stove in the kitchen set.

In the above configuration, the high temperature combustion exhaust b discharged upward from the heat exchanger 2 in the combustion section C of the gas water heater B flows from the secondary air intake port 21 to the ventilation gap 2.
The air a rising through the exhaust box 3 is mixed with the air a rising through the exhaust box 3, and is cooled.
Coupled with the fact that the air is tilted forward, the cold air from outside the device flows smoothly toward the exhaust port 5 of the convex portion 4, and when it reaches the inside of the convex portion 4, the cold air from outside the device flows in from the intake port 6.
a' and the ventilation gap 2 guided by the rectifying guide plate 23
The exhaust air b' cooled to a safe temperature and further mixed with the air a from 2 is smoothly discharged from the exhaust port 5 of the convex part 4 to the outside of the vessel through the rectification and guiding action of the rectification guide plate 23. It is.

In addition, when boiling liquid etc. due to boiling over on the gas table A spills onto the exhaust box 3 and enters into the protrusion 4 from the exhaust port 5, the protrusion 4 protrudes backward from the top of the heat exchanger 2. At the same time, all of the boiling liquid and the like are smoothly flowed out of the vessel from the intake port 6 directly below, and are prevented from entering the combustion section C. At this time, since a dam stop projection 7 is provided at the inner end of the lower part of the convex part 4, intrusion of boiling liquid etc. into the combustion part C is completely prevented. Since the top plate 3a of the exhaust box 3 is tilted forward, all of the boiling liquid c spilled onto the top plate 3a of the exhaust box 3 flows forward through the front surface of the outer shell 1 to the top plate installed on the stoves 8 and 9 of the gas table A. It does not flow into the combustion section C.

Effects of the invention As explained above, in this invention, the high-temperature combustion exhaust discharged from the heat exchanger 2 in the combustion section C of the water heater B is discharged from the ventilation gap 22 in the exhaust box 3 that covers the heat exchanger 2. The exhaust gas mixes with air, and when it reaches the convex portion 4 projecting rearward from the top of the heat exchanger 2, it mixes with air outside the device from the intake port 6, and the exhaust gas cooled to a safe temperature by this double cooling is Since the water is smoothly discharged from the exhaust port 5 to the outside of the container, even if the water heater B is installed at a low position such as on top of the gas stove D in a kitchen set, it can be used safely without the danger of getting burned by the exhaust heat. In addition, even if the boiling liquid caused by boiling over the boiling water on the gas stove A spills onto the exhaust box 3, it will all be directed out of the vessel, so the boiling liquid will not infiltrate into the combustion part C of the water heater B, etc. When gas stove A and water heater B are used at the same time, there is no risk of the combustion part C of water heater B being extinguished due to boiling over, and it is extremely safe to use, and there is no risk of rust due to the infiltration of boiling liquid, etc. Since there is no carbon dioxide, there are effects such as significantly improved durability.
