CN2325680Y - Domestic stove for air-heating - Google Patents

Abstract

The utility model relates to a domestic stove for air heating, which is composed of a stove body, a thermal storage box, a water clamp jacket and a drawer type air door. The heating mode of the water clamping jacket is improved, a single side heating mode of the water clamping jacket is changed into a multiple side heating mode, and the utility model has the advantages of high thermal efficiency and low heat loss. The structure of the air door is improved simultaneously, and the sealing performance of the air door can be enhanced.

Description

The family expenses heating stove

The utility model relates to that family expenses are cooked, the heating stove tool.

At present, rural area or do not have the urban households of collective's heat supply condition is got dim mostly the employing its winter the water leg pipeline is installed in the burner hearth of stove, by heating cold water, utilizes the mode of water circulation heat radiation to carry out, and is commonly called as native dim gas.But in use, find that there is following defective in this stove: 1, water leg itself is heated inhomogeneously, and it is near a side draught heat of flame, and is heat radiation away from a side of flame, and the thermal efficiency is lower.2, seal burner after, heat does not stop in burner hearth, thermal current is because straight-through flue, and it is too fast to cause dispelling the heat, and has wasted heat energy.3, the structure of air inlet also makes its phenomenon that is not closed completely easily in use for some time.

The purpose of this utility model provides the family expenses heating stove after a kind of the improvement, and it can effectively overcome above-mentioned defective.

The purpose of this utility model is achieved in that

On the boiler face of traditional type stove, the one no end of back-off heat storage tank opens crater and outlet flue at the casing upper surface, water leg is installed in the case, water leg is a garden shape or square, and middle hole faces burner hearth, and the water inlet of water leg and delivery port pass box body wall respectively and stretch out.Certain space is arranged between the outside of water leg and the casing, have one to cross quirk on the water leg, after sealing burner, heat in the burner hearth need pass through quirk and enter into space between water leg and the casing, being pooled to outlet flue then could flow out, and crosses the cross section of the cross section of quirk and outlet flue less than the space between water leg and the casing.Air door of the present utility model is designed to the drawer type air door, the drawer is used for connecing slag, and drawer and air door lid are vertical fixing, and the air inlet bottom exceeds one section of drawer chamber, as posting, the air door lid has an angle with below, drawer junction, and when the drawer pushed in the drawer chamber, the posting of air inlet bottom just in time snapped in angle, like this, the drawer makes fulcrum with the posting of air inlet bottom, because deadweight is sagging, makes the air door lid close air door.

Described in detail below in conjunction with accompanying drawing.

Fig. 1 is a structure diagram of the present utility model.

As shown in the figure, heat storage tank 1 is fixed on the shaft 6, and water leg 5 is installed in the case, and the water inlet 9 of water leg 5 and delivery port 8 pass casing and stretch out, and the casing upper surface has crater 2 and outlet flue 4.

Heat in the burner hearth is pressed among the figure direction shown in the arrow and is flowed in heat storage tank 1, when it passed through quirk 7 and entered the outside of water leg 5 and the space between the heat storage tank inwall, because the outside of water leg 5 and the cross section between the casing are greater than the cross section of crossing quirk 7, this moment, heat flow was slow; Again because heat will just can come together in the outflow of outlet flue 4 places, so heat has adequate time and stroke that the water in the water leg is heated through behind this space, thereby improved the thermal efficiency, secondly, because water leg does not directly contact with extraneous, so heat energy loss is little.

The drawer type air door is by air door lid 11 and meet slag drawer 10 and be formed by fixedly connecting, there is an angle its below, junction, posting 12 is arranged at the bottom of air door 13, posting exceeds drawer chamber 14 certain altitudes, after drawer 10 pushes in the drawer chamber 14, because drawer 10 deadweight, can be with posting 12 as fulcrum, make the air door lid closely close air door, play sealing function.

Owing to adopt above-mentioned measure, improved water temperature greatly, reduced thermal losses, do not increase cost again.

Claims (2)

1, a kind of family expenses heating stove, form by shaft, heat storage tank, water leg, drawer type air door, it is characterized in that: heat storage tank tips upside down on the boiler face, crater and outlet flue are opened at the casing upper surface, water leg is installed in the case, hole in the middle of the water leg faces burner hearth, and certain space is arranged between the outside of water leg and the cabinet wall, has one to cross quirk on the water leg; Air door is the drawer type air door, drawer and air door lid vertical fixing, and the air inlet bottom exceeds one section of drawer chamber, and the air door lid has an angle with below, drawer junction.

2, family expenses heating stove according to claim 1 is characterized in that: cross the cross section of the cross section of quirk and outlet flue less than the space between water leg and the cabinet wall
