Abstract

The utility model relates to a water heater using the waste heat of a domestic gas range, which is mainly composed of a water storing tank, an upper and a lower circulating pipes and a heat absorbing coil pipe. The heat absorbing coil pipe is used for replacing a pan supporting frame of the original gas range. The upper parts of the upper and the lower circulating pipes are connected with the water storing tank, the lower parts of the upper and the lower circulating pipes are connected with the heat absorbing coil pipe, and then an integral water heater is formed. When a meal is cooked, the heat absorbing coil pipe can effectively collect the radiant heat of high-temperature flame and the heat in flue gas diffused to environment so that the water temperature in the water heater is raised without affecting the heating effect on a main pot, therefore the utility model has the advantages of heat efficiency enhancement, temperature reduction to kitchen environment, simple structure and convenient use.

Description

A kind of water heater that utilizes civilian right gas stove waste heat

The utility model relates to a kind of residual heat using device, especially a kind of water heater that utilizes domestic gas kitchen range waste heat.

Along with popularizing of combustion gas, people more and more pay close attention to the raising of the gas kitchen ranges thermal efficiency.When improving combustion efficiency by every possible means and selecting reasonable cooker for use, also considered UTILIZATION OF VESIDUAL HEAT IN.As popular in the market garden dish type water heater is exactly one of them.But this water heater exists obviously not enough, mainly be that it will obviously reduce chamber of a kitchen range temperature, the burning of main pot of having slowed down is fried speed, this is that the user least is ready the result that sees, next is that the waste heat of flame carries out from top to bottom to the heating of water heater, the heat exchange effect is bad, if do not fill water, effect is poorer; And filling under the situation of water, if the quantity of cooking is few, the time of hotting plate is short, it is few that possible water temperature improves, and lost the value as hot water, becomes a kind of waste on the contrary; Because the filler is very little, need to add water simultaneously with funnel, very inconvenient.

The purpose of this utility model is exactly that a kind of hot water apparatus that utilizes domestic gas kitchen range waste heat will be provided, and is not reducing under the prerequisite that adds thermal effect of former kitchen range to main pot, utilizes waste heat behind the fuel gas buring to come water in the heating water heater more fully; And the hot water or the boiling water that can have actual utility by the control fork-like farm tool used in ancient China acquisition as one wishes to the water yield, to eliminate unnecessary waste.

The purpose of this utility model is achieved in that whole device mainly is made up of heat absorption coil pipe, circulation line and water storage tank three parts.The curved garden of the pipe of the effective excellent heat conductivity material of absorbing heat disk forms, and the movable chassis of its diameter and former kitchen range is approaching, and the coil pipe number of turns is looked factors such as the size and dimension decision of caliber size, pot, and the heat absorption coil pipe is placed in the position of former kitchen range pot supporter, replaces pot supporter.Water storage tank generally is installed in the back upper place of kitchen range, is operating as prerequisite not influence cooking, as far as possible near the heat absorption coil pipe, tank top has the filler and adds a cover, in order to dustproof and insulation, at the bottom of the water tank and sidewall respectively open a hole, as the interface of circulating water pipe, water storage tank should be incubated; Circulation pipe is the parts that connect heat absorption coil pipe and water storage tank, the wherein tube head of a connection coil pipe foundation ring and the interface of water tank bottom, form circulation pipe down, another root then connects the tube head that encloses on the coil pipe and the interface of water storage tank sidewall, form upper circular tube (also can not be arranged in the bottom if sidewall is not opened interface, but this mouth of pipe must add one section pipe at the bottom of the high outlet); So in water storage tank, cause the difference in height of two mouths of pipe, created the condition of carrying out Natural Circulation, to improve the heat exchange effect.Connect a threeway at the lowest part of following circulation pipe or the suitable position of heat absorption coil pipe foundation ring in addition,, emit hot water with fork-like farm tool used in ancient China by adorning a valve.In the periphery of heat absorption coil pipe one circle is set again and makes and the wide clip of coil pipe of metallic plate, on establish a pot leg rest, connect movable chassis down, this clip also has attractive in appearance and insulation effect.Begin when lighting kitchen range cooking, when flame is discharged with the gap of form between the bottom of a pan and coil pipe of waste gas heating back, the bottom of a pan, must heat the circle of going up of heat absorption coil pipe, the coil pipe around flame also is trapped among with the forms of radiation heating simultaneously, water temperature raises in the pipe, proportion reduces thereby make, flow into water storage tank by upper circular tube, cold water at the bottom of the case then enters coil pipe by following circulation pipe and replenishes the room, accepts heating, and so forth circulation, the water temperature of water storage tank is progressively raise, until boiling.

Adopt the water heater of such scheme,, can not reduce chamber of a kitchen range temperature, influence the thermal effect that adds hardly, and windproof insulation effect is arranged main pot owing to be arranged at the periphery of flame high-temperature region.The heat that water in the coil pipe obtains, only be tidied up flame to around the radiations heat energy that distributes and as the part of the air-flow heat of waste gas discharge, belong to UTILIZATION OF VESIDUAL HEAT IN truly.When obtaining hot water, also reduced the temperature of cooking environment.Because the opening of upper and lower circulation pipe in water tank has difference in height, Natural Circulation is smooth, and heat exchange effect is good.Always be full of water in the coil pipe, pipe can superheating phenomenon not occur and burn, and has guaranteed that water heater has long service life.Because the water yield of heat absorption in the coil pipe is seldom and the amount of water in the water storage tank can arbitrarily be set according to the length of cooking time, for the control water temperature provide may, this just can eliminate because of the too little wasting phenomenon that loses actual utility that heats up.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the water heater first embodiment schematic diagram

Fig. 2 is the water heater second embodiment schematic diagram

Among the figure: 3 times circulation pipes of 1 water storage tank, 2 upper circular tubes, 4 threeways, 5 heat absorption coil pipes, 6 valves, 7 clips

In figure one, the sidewall interface that tube head extends to water storage tank (1) is enclosed in going up of heat absorption coil pipe (5), through being connected to form upper circular tube (2); The following circle tube head of coil pipe (5) is connected with the bottom outlet of following circulation pipe (3) with water storage tank (1) by threeway (4), the other end of threeway (4) is loaded onto Draw off valve (6), the position of valve (6) should be in the minimum point of whole device, so that water is drained, clip (7) is installed in the periphery of coil pipe (5)

In the embodiment shown in the figure two, the upward circle tube head of coil pipe (5) extends into upper circular tube (2) and is connected with a hole of water storage tank (1) bottom, and exceeds the bottom surface certain altitude; The following circle tube head of coil pipe (5) also extends to another hole of water storage tank (1) bottom, connects the back and forms circulation pipe (3) down, opens the intercommunicating pore valve (6) of burn-oning in the appropriate location in the following circle outside of coil pipe (1); The periphery of coil pipe (5) is provided with clip (7).
