Detailed description of the invention

As shown in Figures 1 to 5, kitchen range top waste-heat recovery device of the present utility model, comprises burner 1, heat pipe 2, heat pipe sleeve pipe 3 and jacket pipe 4.

Heat pipe 2, except two end portions, is all placed in the heat pipe sleeve pipe 3 communicated with cold water pipe 31, and the inner side of heat pipe sleeve pipe 3 and the outside of heat pipe 2 form toroidal cavity 32, and the lower end of heat pipe sleeve pipe 3 is connected with the outer side seal of heat pipe 2.

Heat pipe sleeve pipe 3 is placed in jacket pipe 4, and jacket pipe 4 lower end is connected with the outer side seal of heat pipe sleeve pipe 3, and forms annular opening 321 with the outside of heat pipe 2 inside the upper end of heat pipe sleeve pipe 3, and toroidal cavity 32 is communicated with jacket pipe 4 by annular opening 321.

The lower end of heat pipe 2 is provided with the heat absorption circle 21 be nested with outside burner 1, and heat absorption circle 21 is for absorbing burner exhaust heat, and its upper end is straight pipe shape, is arranged in jacket pipe 4, for the heating of cold water.

Jacket pipe 4 is connected with hot water conduit 411, and hot water conduit 411 is connected with hot-water line 4111, and hot-water line 4111 outwards provides hot water.

Below in conjunction with the drawings and specific embodiments, concrete structure of the present utility model is described in detail.

In specific embodiment, as shown in Figure 5, the bore of heat pipe sleeve pipe 3 is greater than the pipe external diameter of heat pipe 2, heat pipe 2 is inserted in heat pipe sleeve pipe 3, and the outside of the lower end of heat pipe sleeve pipe 3 and heat pipe 2 is connected and sealed by welding manner, thus the inner side of heat pipe sleeve pipe 3 and the outside of heat pipe 2 form toroidal cavity 32.

Cold water pipe 31 is connected with the side of heat pipe sleeve pipe 3, when passing into cold water in cold water pipe 31, cold water enters in toroidal cavity 32, cold water is started heating by heat pipe 2 in toroidal cavity 32, because toroidal cavity is narrow and small, so contact area is large when cold water flows in this space, can be heated rapidly.

As shown in Figure 4, heat pipe sleeve pipe 3 inserts in the opening arranged bottom jacket pipe 4, and is connected and sealed by welding manner by the outer wall of the opening bottom jacket pipe 4 and heat pipe sleeve pipe 3; Now, the water be in toroidal cavity 32 enters into jacket pipe 4 through annular opening 321, utilizes the upper end of heat pipe 2 to continue heating.Meanwhile, the dischargeable capacity of jacket pipe 4 is far longer than the dischargeable capacity of toroidal cavity 32, forms a hot water stores location, due to enlarged volume herein, as shown in Figure 3, temporarily can store hot water.

As shown in Figure 3, the lower end of heat pipe 2 is provided with the heat absorption circle 21 be nested with outside burner 1, and heat absorption circle 21 is for absorbing burner exhaust heat, and certainly, the lower end of heat pipe 2 also can be the straight tube stretching into flame.Preferably, the lower end of heat pipe 2 arranges heat absorption circle 21 is for obtaining better heat transfer and heating effect.In specific embodiment, heat pipe 2 is canal formula Super-conductive conduit preferably, canal formula Super-conductive conduit is by inventor's Qu Yuzhi teaching inventive residing in American, it has excellent heat transfer efficiency, and there is the characteristic of stow away from heat end temperature higher than heat source end, therefore, the utilizing status of waste heat effectively can be improved in the utility model.

At present, because canal formula Super-conductive conduit has application in many industries, person of ordinary skill in the field can easily obtain, and therefore, is not described in detail.

As shown in Figure 3, the airtight barrel shaped structure that jacket pipe 4 is made for stainless steel material, be mainly used in stored hot water, jacket pipe 4 is connected with hot water conduit 411, and hot water conduit 411 is connected with hot-water line 4111.In concrete use, the hot water in jacket pipe 4 drains in hot-water line 4111 through hot water conduit 411, outwards provides hot water.

In the utility model, water circulation adopts the pressure-bearing type method of operation, and namely jacket pipe 4 is connected with cold water pipe 31 and hot-water line 4111, and when there being hot water to be consumed, cold water fills into automatically, thus reaches a dynamic circulation.

Improve as one, one end of hot-water line 4111 is connected with tap 5 and water tap 51, and now, tap 5, in concrete use, directly can arrange with kitchen, thus conveniently take hot water.

Improve as one, the upper end cover of jacket pipe 4 can be opened, so that the incrustation scale in cleaning jacket pipe 4, in a particular embodiment, the upper end cover of jacket pipe 4 can be arranged to the shape of similar water cup/lid, and both are threaded connection, because this kind of mode is easy to implement for person of ordinary skill in the field, at this, be not described in detail.

Improve as one, heater is provided with in jacket pipe 4, and outside is provided with temperature indicator, when gas-cooker is shorter for service time, in jacket pipe 4, water temperature is too low when not reaching instructions for use, heat the water at low temperature in jacket pipe 4 by water heater, to obtain temperature required hot water, the actual temp of water shows by temperature indicator.

Because heater and temperature indicator are very common in the prior art, person of ordinary skill in the field is easy to obtain, and at this, is not described in detail.

Because the gas-cooker used in life is generally two stove version, therefore, in a particular application, the kitchen range top waste-heat recovery device that the utility model describes in technique scheme, will arrange two usually, i.e. corresponding one of each stove mouth, in such cases, as shown in Figures 1 to 3, two jacket pipes 4 are connected by tube connector 41, and now hot water conduit 411 is directly connected with tube connector 41.

In addition, heat pipe sleeve pipe 3 in technique scheme, cold water pipe 31, tube connector 41, hot water conduit 411 and hot-water line 4111 are stainless steel material and make, and its curved shape is shown in shown in Fig. 1 to Fig. 3, certainly, can need to arrange its curved course according to concrete installation, be not described in detail at this.In concrete installation process, heat pipe sleeve pipe 3 and cold water pipe 31 etc. all can be embedded in kitchen wall, thus effectively saving takes up room.

Except the technical characteristic described in description, be the known technology of those skilled in the art.

The above has made detailed description to preferred embodiment of the present utility model and embodiment by reference to the accompanying drawings; but the utility model is not limited to the above-described embodiment and examples; for those skilled in the art; without departing from the concept of the premise utility; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
