Example 1

As shown in fig. 1-3, the waste heat recovery type water heater for the gas stove comprises a hot water tank 1 arranged at the top end of a back plate of a cooking bench 4 and a water injection assembly 3 for maintaining the water level of the hot water tank 1, and further comprises a waste heat recovery assembly 2, wherein the hot water tank 1 is divided into an upper area and a lower area which are communicated by a partition plate, the upper end is a hot water area 11, the lower end is a cold water area 12, the hot water area 11 is communicated with a return pipe 21, the cold water area 12 is communicated with a cold water pipe 22, a heating pipe 23 for recovering waste heat is arranged in a pot seat 5 of the cooking bench 4, the bottom end of the heating pipe 23 is communicated with the cold water pipe 22, and the top end of the heating pipe 23 is communicated with the return pipe 21.

The natural water circulation is formed through the principle of thermal expansion and cold contraction, the hot water tank 1 is arranged at a position higher than the cooking bench 4, water heated by the cooking bench 4 can rise through the return pipe 21 to enter the hot water area, cold water correspondingly enters the heating pipe 23 through the cold water pipe 22, the water rises again after heating, the water meets the principle of thermal expansion and cold contraction after the water is at a temperature higher than 4 ℃ according to the physical property of the water, the density of the hot water is lower, the density of the cold water (higher than 4 ℃) is higher, the hot water area 11 and the cold water area 12 can also prevent the convection of the hot water and the cold water, the heat conduction efficiency of the water is low under the condition that no convection occurs, and therefore, the heat neutralization of the hot water in the hot water area 11 and the cold water in the cold water area 12 is slower.

In order to facilitate the use of the hot water in the hot water zone 11, the side wall of the hot water tank 1 is extended outwards from the hot water zone 11 with a faucet 13 or a hose is externally connected, but the height of the hose cannot be higher than the water level of the hot water tank 1.

The water injection assembly 3 comprises a cylinder 31 penetrating through a partition plate, the bottom end of the cylinder 31 is communicated with the cold water area 12, the top end of the cylinder 31 is higher than the water level of the hot water tank 1, a liquid level ball float valve 33 is arranged at the top end of the cylinder 31, a running water pipe 32 extending into the cylinder 31 and connected with the liquid level ball float valve 33 is arranged at the bottom end of the hot water tank 1, the water injection assembly 3 is used for keeping the water level in the hot water tank 1 and is controlled by the liquid level ball float valve 33, but the liquid level ball float valve 33 needs to be arranged above the water surface, namely, is arranged in the hot water area 11, and injected cold water should enter the cold water area 12, so the running water pipe 32 is sheathed with the cylinder 31, and the cylinder 31 is not communicated with the hot water area 11 although extending to the hot water area 11, and the cold water in the cylinder 31 enters the cold water area 12 downwards.

The communicating position of the hot water area 11 and the cold water area 12 is positioned at one end of the hot water tank 1, and the cold water pipe 22 is far away from the communicating position, so that the water entering the cold water pipe 22 is far away from the hot water, and the temperature is prevented from being mutually neutralized.

The heating pipe 23 is spirally wound on the surface of the inner cavity of the pot seat 5, so that the waste heat utilization efficiency is improved.

The implementation mode specifically comprises the following steps: the inside residual temperature of pot seat 5 heats heating pipe 23, and hot water density reduces, enters into hot water district 11 along back flow 21, and the water of corresponding cold water district 12 passes through cold water pipe 22 and gets into heating pipe 23 to this circulation flows, and continuous heating to for pot seat 5 cooling, when hot water is discharged from tap 13 back, is supplied tap water through water injection subassembly 3, and automatic replenishment device is controlled through liquid level ball cock 33, and is led into cold water district 12 through drum 31 with the tap water that supplies, forms the hydrologic cycle through the physical property of water, and is higher to the utilization efficiency of residual heat, and heating effect is better.

The foregoing examples illustrate only a few embodiments of the utility model and are described in detail herein without thereby limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
