Abstract

The utility model relates to a water heater for stoves or ranges. A heat exchange system is composed of an upper water chamber, a lower water chamber, a double-layer pipe, a single layer pipe, and a cavity arranged in a casing. The utility model is characterized in that the upper water chamber, the lower water chamber, the double-layer pipe and the single layer pipe are arranged in the cavity formed by the casing and a heat collecting base. At least one double-layer pipe is used and an external layer pipe and an interlayer of the double-layer pipe are communicated with the upper water chamber and the lower water chamber. An inner layer pipe passes through the upper water chamber and the lower water chamber, an upper port is communicated with the cavity, a lower port is communicated with the heat collecting base, the upper end of the single layer pipe is communicated with a water outlet pipe, the lower end of the single layer pipe is communicated with the lower water chamber, and the water inlet pipe is communicated with the upper water chamber. The utility model can be matched with a plurality of stoves using coal, gas, oil, etc. The utility model has the advantages of special design, strong heat exchange ability, fast speed of temperature rising, and low temperature of the external surface of the casing.

Description

Water heater for stove or range

The utility model belongs to heat-exchange device, particularly a kind of cooking stove water heater.

At present, the water heater of selling on the market has gas heater, electric heater and solar water heater etc., provides convenience to daily life.But the energy that above-mentioned water heater uses is single, is subjected to region restriction and other as factor affecting such as having a power failure, stop the supple of gas or steam, brings a lot of inconvenience again for the user.

It is the gas range water heater of CN2041785U and the honeycomb briquette coiled water heater of CN2085506U that China's utility model patent communique discloses notification number.These two kinds of water heaters can both be used with cooking stove, but the structure slightly complicated, it is also convenient inadequately to move.

The purpose of this utility model is to form heat-exchange system by the last lower header, bimetallic tube, mono-layer tube and the cavity that are provided with in the housing, and its thermal-arrest base can match with various cooking stoves, and is rational in infrastructure, ingenious, overcome the deficiency of prior art.

The technical solution of the utility model is: housing is provided with water inlet pipe, outlet pipe, exhanst gas outlet.In the cavity that housing and thermal-arrest base are constituted, upper tank, lower header, bimetallic tube and mono-layer tube are housed.The outer tube of bimetallic tube and interlayer are communicated with last lower header, and inner tube is passed lower header, and its upper port is communicated with cavity, lower port is communicated with the thermal-arrest base.The upper end of mono-layer tube is communicated with outlet pipe, the lower end is communicated with lower header.Water inlet pipe is communicated with last chamber.

Housing is by outer wall, inwall and place the adiabator layer between two walls to constitute, and on the housing outer wall handle is housed.

Being communicated with the mono-layer tube of outlet pipe and lower header, is the outside that is coiled in one group of bimetallic tube, prolongs its length, increases the flow process of water.A dividing plate vertical with bimetallic tube is housed at least, in order to increase the flow process of hot flue gas on the inwall in cavity.

The utility model compared with prior art has following advantage:

1. adopt bimetallic tube to be communicated with and go up lower header, design is unique, ingenious, and bimetallic tube interlayer volume is little, water by the time two sides be heated, heating surface area is big, exchange capability of heat is strong, quick heating.

2. housing divides inside and outside wall, heat-insulation layer between Liang Bi, appearance looks elegant, and hull-skin temperature is low.

3. applied widely to thermal source, available coal, gas, the multiple cooking stove of wet goods are made thermal source.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1: the utility model is along the housing longitudinal sectional view.

The utility model is described in further detail below in conjunction with embodiment:

As shown in Figure 1, housing is made of the adiabator layer 3 between outer wall 1, inwall 2 and two walls thereof.Housing is provided with water inlet pipe 4, outlet pipe 5, exhanst gas outlet 6 and is contained in handle 7 on the outer wall 1.Be equipped with in the cavity 9 that housing and thermal-arrest base 8 formed upper tank 10, lower header 11, by inner tube 12 and outer tube 13 and between interlayer 14 bimetallic tube and the mono-layer tube 15 that constitute.The outer tube 13 of bimetallic tube and interlayer 14 are communicated with upper tank 10, lower header 11, and the upper port of its inner tube 12 is communicated with cavity 9, lower port is communicated with lower header 11.A dividing plate vertical with bimetallic tube 16 also is housed on the inwall 12 in the cavity 9.

Workflow of the present utility model is: hot flue gas, is flowed out from exhanst gas outlet 6 through inner tube 12, cavity 9, pile warp thermal insulation board 16 by thermal-arrest base 8.Cold water enters upper tank 10 from water inlet pipe 4, and via interlayer 14, lower header 11 and mono-layer tube 15 become hot water, is flowed out by outlet pipe 5.

Claims

1, a kind of cooking stove water heater, include housing, thermal-arrest base, be arranged on water inlet pipe, outlet pipe and exhanst gas outlet on the housing, it is characterized in that in the cavity of housing and thermal-arrest base composition, upper tank, lower header, bimetallic tube and mono-layer tube being housed, bimetallic tube is at least one, its outer tube and interlayer are communicated with upper tank and lower header, and inner tube is passed lower header, upper port and is communicated with cavity, lower port is communicated with the thermal-arrest base, the upper end of mono-layer tube is communicated with outlet pipe, the lower end is communicated with lower header, and water inlet pipe is communicated with upper tank.

2, cooking stove water heater according to claim 1 is characterized in that described housing is made of the insulation material layer between outer wall, inwall and two walls, and on the housing outer wall handle is housed.
