Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a washing machine equipped with a boiler that is mainly used for washing civil engineering machinery and agricultural machinery, and is particularly applicable to washing machines that are used in mountains, riverbeds, farms, rice fields, etc. The present invention relates to a washing machine equipped with a boiler that can be used outdoors in places without power supply facilities.

[Conventional technology]

Washing machines equipped with boilers, which have been commonly used in the past, were developed mainly for the purpose of washing automobiles and various engines, such as turbine engines for aircraft. Those disclosed in Japanese Patent Application Laid-Open No. 57-050692 are known.

Washing machines equipped with this type of boiler can use the power supply facilities of maintenance shops, so the washing water (liquid)
The injection pump was driven by an electric motor.

The boiler is a closed type boiler, and the water supply to this boiler is directly connected to the water supply facility via a pressure reducing check valve to prevent hot water heated by the boiler from flowing back. That's what I was doing.

In addition, safety valves were used to prevent explosions in the boilers.

[Problem that the invention attempts to solve]

The above-mentioned conventional washing machine equipped with a boiler cannot wash various industrial machines used outdoors (mountains, rivers, farms, etc.) where there is no power supply facility at the work site.

Furthermore, since it was necessary to provide a pressure reducing check valve and a safety valve, there was a problem in that costs increased accordingly.

[Means for solving problems]

In order to solve the problems of the prior art described above, the washing machine equipped with a boiler of the present invention is provided with a pair of moving wheels 11 and 12 at the front and rear of the bottom surface of the square boiler 1, and a pair of moving wheels 11 and 12 are provided at the front and rear of the bottom surface of the square boiler 1. A hot water injection pump 2 is provided at the rear side, and an engine 3 with a power generation function for driving the pump 2 is provided at the rear side of the engine 3. Further, a cistern 4 having a water intake port 41 and the square boiler are installed at the rear side of the engine 3. a chimney 5 leading to the combustion chamber of the boiler 1;
It is equipped with a steam outlet 6 that leads to a water tank.

[Effect]

Since the hot water injection pump 2 is driven by the engine 3, the washing machine equipped with this boiler can be used at outdoor work sites where there is no power supply facility.

Since water is supplied from a water supply source such as tap water to the water intake port 41 of the cistern 4, and a steam outlet 6 is provided in the water tank of the boiler 1, hot water can be supplied without installing a pressure reducing check valve or a safety valve. It is possible to prevent water from flowing back into the water supply or causing the boiler 1 to explode.

〔Example〕

Hereinafter, a washing machine equipped with the boiler of the present invention will be described in detail based on the drawings.

As shown in FIGS. 1 to 4, the burner 13
The rectangular boiler 1 is equipped with flexible wheels 11 on both sides of the front end and fixed wheels 12 on both sides of the rear end of the bottom surface of the square boiler 1, so that the boiler 1 can be automatically moved freely.

A pump 2 for hot water injection is attached to the front end of the upper surface of the rectangular boiler 1, and an engine 3 equipped with a power generation function for driving the pump and for obtaining electric power is attached to the rear side, and the upper surface of the rectangular boiler 1 is attached to the rear side. A cistern 4 equipped with a water intake port 41 for introducing water from a water source such as tap water at the rear end, a chimney 5 communicating with the combustion chamber of the boiler 1, and a steam outlet 6 communicating with the water tank of the boiler are attached, While the whole body is compact in a rectangular shape, it is constructed to prevent backflow of hot water to the tap (water source) and prevent the boiler 1 from exploding.

[Effect of idea]

According to the present invention, a cleaning machine equipped with a boiler can be used to clean various industrial machines at outdoor work sites where there is no power supply facility.

And, even without installing a pressure reducing check valve or safety valve,
This simple and inexpensive structural modification has the advantage of preventing hot water from flowing back into the water supply and preventing the boiler from exploding.
