Abstract

The utility model relates to a chimney used for a commercial furnace. An inner-layer pipe is bushed with an outer-layer to form the utility model and a circulation-water cavity is arranged between the two pipes. The upper end and the lower end of the circulation water chamber are sealed. A plurality of heated pipes which are communicated with the circulation water chamber is pre-arranged in the inner-layer pipe. A circulation water outlet is pre-kept on the lower part of the outer-layer pipe and a circulation water inlet is pre-kept on the upper part of the outer-layer. The protruding stages are arranged on the upper-end face and the lower-end face between the inner-layer pipe and the outer-layer pipe, and the upper end-face of the protruding stage is connected with an outer-connecting chimney and the lower end face of the protruding stage is connected with the furnace body. With the structure, the heat energy lost by the furnace can be effectively used to heat water, thus saving the energy.

Description

A kind of chimney of commercial stove and accessory

Technical field:

The utility model relates to a kind of chimney that is exclusively used in commercial stove and accessory.

Background technology:

Today that the energy is more and more nervous, energy saving and environment friendly product more and more obtains people's approval, for example electricity-saving lamp, energy-saving refrigerator etc., but still have a lot of product energy consumptions big, energy waste is serious, as commercial stove and accessory, in its process of preparing food, produce the waste gas that has heat energy in a large number and be discharged from, and the ratio that this part heat energy accounts for is quite big by chimney, if insufficient this part heat energy that utilizes is wasted very serious.

Summary of the invention:

The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, to provide a kind of heat energy that makes full use of in the chimney, the commercial stove and accessory chimney of energy savings.

For achieving the above object, the technical scheme that the utility model provides is: a kind of chimney of commercial stove and accessory, it is formed by inner tube and outer tube suit, be provided with circulating water cavity between two pipes, the upper and lower end sealing of circulating water cavity, preset many heat pipes that communicate with circulating water cavity in the inner tube, be reserved with circulating water outlet in the outer tube bottom, and top is reserved with the recirculated water inlet, upper and lower end face between inner tube and the outer tube all is provided with boss, the boss of upper surface is connected with external chimney, and the boss and the body of heater of lower surface join.

When this chimney water heater uses, cold water pipeline from the outside enters circulating water cavity through the recirculated water inlet, cold water reaches the heat pipe that communicates with it at circulating water cavity and is heated, heated hot water flows in the heat-preserving container from circulating water outlet and preserves, at any time use for people, prevent that effectively the heat energy of stove and accessory runs off from chimney.

Description of drawings:

Fig. 1 is the cutaway view of the utility model preferred embodiment;

Fig. 2 is the vertical view of the utility model preferred embodiment;

Fig. 3 is the stereogram of the utility model preferred embodiment.

The specific embodiment:

Elaborate the utility model below in conjunction with a preferred embodiment:

Shown in accompanying drawing 1～accompanying drawing 3, the chimney water heater of this preferred embodiment, it is formed by two tubing suits not of uniform size, be provided with circulating water cavity 1 between two pipes, on the circulating water cavity 1, lower end closed, preset many heat pipes 3 that communicate with circulating water cavity 1 in the inner tube 2, because the existence of heat pipe 3, more can absorb heat energy fully, in be reserved with recirculated water inlet 5 on outer tube 4 tops, this recirculated water inlet 5 joins with the water pipe of outside, and outer tube 4 bottoms are reserved with circulating water outlet 6, and this circulating water outlet 6 joins with heat-preserving container, between inner tube 2 and the outer tube 4 on, the lower surface all is provided with boss 7, the boss of upper surface is connected with external chimney, and the boss and the body of heater of lower surface join.

Claims

1, a kind of chimney of commercial stove and accessory, it is characterized in that: it is formed by inner tube and outer tube suit, be provided with circulating water cavity between two pipes, many the heat pipes that communicate with circulating water cavity are preset in the upper and lower end sealing of circulating water cavity in the inner tube, be reserved with circulating water outlet in the outer tube bottom, and top is reserved with the recirculated water inlet, upper and lower end face between inner tube and the outer tube all is provided with boss, and the boss of upper surface is connected with external chimney, and the boss and the body of heater of lower surface join.
