Abstract

The utility model discloses an enclosed gas water heater casing which is matched with a gas water heater. The utility model is characterized in that an air inlet hole is arranged on the casing; mounting holes by which a gas supply pipe, a water inlet pipe, a water outlet pipe and an ignition switch button can be arranged; the upper part of the casing is provided with a gas collecting hood which is connected with an exhaust pipe led out from the casing; an air inlet pipe is installed on the casing whose air inlet is arranged on the air inlet pipe. When the casing is installed, the air inlet pipe and the exhaust pipe can be led out of a bathroom through the holes in the bathroom; the fresh air outside the bathroom can go into the gas water heater; the waste gas after combustion can be exhausted out of the bathroom. The utility model has the advantages that the use is convenient and safe; the gas water heater can be used in the bathroom.

Description

Enclosed gas water heater casing

The utility model relates to a kind of gas heater.

Along with the raising of living standards of the people, gas heater has entered huge numbers of families.People utilize natural gas, coal gas, liquefied gas to act as a fuel, and use gas heater to add the warm water and have a bath very convenient.The general gas water heater is that gas ignition mouth, water heater are housed in housing, and the gas ignition mouth is connected to Gas Pipe, and the import and export of water heater is connected to inlet tube and outlet tube respectively, and lower part of frame has air inlet, and the top of housing is worn-out mouthful and is exhaust outlet.During use, the combustion gas of coming out in the gas ignition mouth is lighted, and adds hot-water heater, and hot water comes out just can have a bath from outlet pipe endlessly, and air enters from the air inlet of housing, and drain from the exhaust outlet of housing combustion-supporting reaction back.If water heater is installed in the bathroom, general bathroom is all airtight, will cause the bathroom anoxic after using a period of time, because generation in China's accident of causing death that had that when using water heater to have a bath human body anoxia suffocates and carbonic oxide is poisoned, therefore national departments concerned is produced the structure of various water heaters at present according to China, make the regulation of forbidding with chamber installation water heater, promptly require the combustion chamber of water heater and shower nozzle will be contained in two Room respectively.Divide two Room that the danger that can remove because of anoxic causes human body to suffocate and carbonic oxide is poisoned is installed, but very inconvenient in the use, because ignition switch is outside away from the bathroom, the person of having a bath can't operate, can not regulate water temperature and open fire in the pass, not only inconvenient but also cause the significant wastage of the energy.

The purpose of this utility model provides a kind of closed gas heater housing, this housing can mate with the core body of general gas water heater, can break through gas heater can not be with the forbidden zone of chamber installation, both do not had the danger that human body anoxia asphyxia and carbonic oxide are poisoned, and can operate the ignition switch and the adjustment turn-button of water heater again easily.Advantage with convenience, safety.

Main points of the present utility model are, change the gas heater housing of common worn-out mouthful formula into closed, and promptly exhaust outlet is drawn outside the housing by pipeline.When installing and using, gas heater can directly be installed in the bathroom like this, and the exhaust outlet of gas heater is drawn outside the bathroom by pipeline, and is directly to discharge waste gas after burning outside the bathroom, safe and convenient.

Be elaborated below in conjunction with accompanying drawing.

Fig. 1 is closed gas heater housing and core body combination scheme of installation

Fig. 2 is row, the air inlet pipe schematic diagram of closed gas heater housing

As shown in Figure 1 and Figure 2, on the closed gas heater housing 1 air inlet 12 is arranged, and be provided with the installing hole that can supply Gas Pipe 2, water inlet pipe 3, outlet pipe 4 and ignition switch button 5 to install, and a gather qi together cover 8 is equipped with on the top in this housing 1, and this gather qi together cover 8 is connected to blast pipe 7 and draws outside the housing.Can directly outside the bathroom, discharge waste gas after burning by blast pipe 7 like this.

Consider from another angle of problem, can in the gas heater housing, draw fresh air, help burning by air inlet pipe.As shown in Figure 1 and Figure 2, on the described housing 1 air inlet pipe 6 is housed, the air inlet 12 of described housing 1 is located on this air inlet pipe 6.Closed gas heater housing 1 is cooperating with the gas heater core body when installing, and is that the water heater 9 with core body places the gather qi together cover 8 times, and gas ignition mouth 10 places again under the water heater 9.The water inlet pipe 3 of water heater 9, water outlet device 4, the Gas Pipe 2 that is connected with gas ignition mouth 10 and some shift knob 5 thereof are drawn outside the housing 1 by installing hole separately respectively.Housing 1 is a closed, can be formed by two half housing butt joints, and except that air inlet pipe 6, blast pipe 7 were connected with outside air, whole housing all was airtight.During installation air inlet pipe 6, blast pipe 7 are drawn outside the bathroom.Like this can be in the bathroom switch fire and to regulate water temperature very convenient, very safe again.

As shown in Figure 1 and Figure 2, described air inlet pipe 6 is positioned at the top of described housing 1, described blast pipe 7 parallel passing and drawing outside the described housing 1 among the described air inlet pipe 6.Make two pipes become a pipe like this, it is just much of that only to need to make a call to a hole on shower wall, more helps installing.

As shown in Figure 1 and Figure 2, described blast pipe 7 is a nail-shaped, and its big end exposes outside described air inlet pipe 6, and the exhaust outlet 14 of this blast pipe 7 is located on the sidewall of its big end, and the air inlet 12 of described air inlet pipe 6 is located on its sidewall.Air inlet 12, exhaust outlet 14 all are the Tiaokou porous type, and evenly distributed week on sidewall separately respectively.

As shown in Figure 1 and Figure 2, during installation, the bathroom wall is made a call to a hole, air inlet pipe 6 is passed from hole, and air inlet 12, exhaust outlet 14 are exposed outside the bathroom.In use, after opening combustion gas gas ignition mouth 10 is lighted, make heater 9 heating, produce hot water endlessly, simultaneously, fresh air enters by air inlet pipe 6 from air inlet 12 and enters in the housing 1, and burning back hot waste gas rises and assembles the back at gather qi together cover 7 and discharge outside the bathroom from exhaust outlet 14 by blast pipe 7.Fresh air constantly enters in the gas heater outside the bathroom, the waste gas of gas heater is constantly discharged outside the bathroom again, therefore can remove the danger of human body because of anoxia asphyxia and carbonic oxide poisoning, can optionally open fire when having a bath simultaneously and regulate water temperature, if gas heater breaks down, also can in time find, get rid of rapidly.This housing cooperates with the gas heater core body to install and breaks through the forbidden zone that water heater can not be installed with the chamber, not only convenient but also safety.
