Description

[Detailed description of the invention] The present invention relates to a portable water heater that uses gas as a heat source.Furthermore, the present invention has a vertical overall structure to reduce the bottom area of the vessel, and the overall structure is A portable water heater that is compact, can boil a certain amount of water anywhere, indoors or outdoors, and can easily transfer the boiled water to another hot water receiver such as a pot. The purpose is to provide the following.

Hereinafter, the water heater of the present invention will be explained based on the illustrated embodiment. In FIGS. 1 and 2, reference numeral 1 is the main body of the gas water heater, 2 is a liquid tank, 3 is an annular gas burner, and 6 is a cassette. In the type gas cylinder, 10 indicates a main body casing consisting of a lower case 11 and an upper case (protective case that also serves as a windshield) 12.

This water heater has a protective case 1 having an upper exhaust port 12b.
An annular gas burner 3 is installed inside the gas burner 2, and the liquid tank 2 is suspended above it.
A hot water outlet pipe 24 extending downward is attached to the outlet 24.
a is opened at a position below the gas burner 3.

Inside the lower case 11 of the main body casing 10 is a partition wall 11
A space 15 for accommodating a cylinder chamber 13 and a hot water receiver 7 is formed by partitioning by a.

A cassette type gas cylinder 6 is housed in the cylinder chamber 13 in the vertical direction.

An adapter 8 is fitted into the nozzle 6a of the gas cylinder 6, and gas is sent to the gas burner 3 by operating a gas adjustment knob 18.

The gas cylinder 6 is fitted into or removed from the adapter 8 by operating the cassette attachment/detachment lever 20.

An outward flange 2b is formed at the upper end of the liquid tank 2, and the liquid tank 2 is suspended within the protective case 12 by hooking the flange 2b to the upper opening 12H of the protective case 12. .

Gas burner 3 is attached to bottom plate 12b of protective case 12 with screw 1.
It is installed by 9.

The gas burner 3 has a gas outlet 33 arranged radially outward and a gas outlet 34 formed on the inner surface of a circular hole 32 in the center.

The outlet 24 a of the hot water outlet pipe 24 is located above the hot water receiver 7 accommodated in the cavity 15 .

The hot water outlet pipe 24 extends downward through the center of a circular hole 32 formed in the center of the gas burner 3, and a cock 25 that is opened and closed by a knob 26 is attached to the middle part thereof.

A cover 27 is attached to the lower end of the hot water outlet pipe 24 to prevent hot water droplets from scattering.

The upper opening of the liquid tank 2 is hermetically closed with a lid 21.

An O-ring 23 is attached to the lower surface of the lid 21, and this O-ring 23 contacts the outward flange 2b of the liquid tank 2 to keep it airtight within the liquid tank 2.

The outer circumference 2C of the liquid tank flange 2b and the outer circumference 21 of the lid 21
A and A can be removably connected to each other by a method such as a helicoid connection or a screw connection.

A pressure regulating valve 22 (also serving as a safety valve) for regulating the pressure inside the liquid tank 2 is attached to the lid 21 .

When using the illustrated water heater, water is first poured into the liquid tank 2, the liquid tank 2 is sealed with the lid 21, and then the gas burner 3 is ignited.

Since the liquid tank 2 is surrounded by a protective case 12 that also serves as a windshield, hot air also fills the side space 14 of the liquid tank 2, heating the water in the liquid tank 2 from the bottom and side periphery. It is possible to improve heating efficiency and shorten heating time.

The flame ejected from the gas outlet 34 at the center of the gas burner heats the hot water outlet pipe 24 and also heats the water within the pipe.

In addition, since the inside of the liquid tank 2 is sealed and the pressure can be raised to above atmospheric pressure using the pressure regulating valve 22, the water inside the liquid tank 2 quickly reaches a high temperature (100°C or more is possible). Can be heated.

When the water in the liquid tank 2 boils, the hot water can be taken out into the hot water receiver 7 by operating the knob 26 and opening the cock 25.

Note that reference numerals 16 and 17 in the figure indicate air windows.

Next, to explain the effects of the present invention, the portable water heater of the present invention has the following effects.

(1) Since the liquid tank 2, gas burner 3, and space 15 for housing the hot water receiver are arranged vertically, the bottom area of the water heater can be reduced, and the entire water heater can be made compact. Can be configured.

(2) Since gas is used as the heat source, it has strong firepower and can boil a certain amount of water quickly and easily. Furthermore, since it uses a cassette-type gas cylinder, it is convenient to carry and can be used indoors or outdoors. You can boil a certain amount of water anywhere.

(3) A hot water outlet pipe 24 with a cock 25 is provided at the bottom 2a of the liquid tank 2, and the outlet 24a of the hot water outlet pipe 24 is located below the gas burner 3, and an appropriate hot water receiver 7 is provided. Since the opening is made in the cavity 15 for accommodating, boiled water can be easily transferred to another hot water receiver such as a pot.

In addition, as in the illustrated embodiment, the gas burner 3 and the liquid tank 2
When it is stored in the protective case 12 that also serves as a windshield, the firepower is less likely to be weakened by the wind even when used outdoors, and the heating efficiency is good and the water can be boiled quickly.

Further, if a pressure regulating valve 22 is provided on the lid 21 to maintain the inside of the liquid tank 2 at a pressure higher than atmospheric pressure, hot water at a high temperature can be quickly obtained.

Furthermore, if the hot water outlet pipe 24 extends downward through the center of the gas burner 3, the water within the hot water outlet pipe 24 can also be heated.

Furthermore, if a cassette-type gas cylinder is used as a heat source and is set vertically as in the illustrated embodiment, it is easy to replace the gas cylinder, and the water heater can be made more compact in plan view. This further enhances the effect of
