Description

Technical Field

[0001] This utility model relates to the field of thermal energy technology, specifically a structure for recovering and utilizing waste heat from a gas stove. Background Technology

[0002] A gas stove is a kitchen appliance that uses liquefied petroleum gas (LPG), manufactured gas, natural gas, or other gaseous fuels for direct-fire heating. Gas stoves are also called cooktops. Based on the gas source, gas stoves are mainly divided into LPG stoves, manufactured gas stoves, and natural gas stoves. Based on the number of burners, gas stoves can also be divided into single-burner, double-burner, and multi-burner stoves.

[0003] However, the existing gas stoves on the market currently have a burner core installed inside the burner, with only a pot bottom support around the burner core. When the gas stove is working, a large amount of high-temperature waste heat is lost from the area around the burner head and is not utilized, resulting in energy waste. In addition, the pot bottom support bracket is exposed to high temperatures for a long time, resulting in a large temperature rise, slow heat dissipation, and easy aging and deformation. Therefore, the existing gas stove structure is too simple, the waste heat is not effectively recovered and utilized, resulting in a large amount of heat waste, and the temperature of the gas stove bracket is difficult to drop, resulting in a short service life. Utility Model Content

[0004] The purpose of this utility model is to provide a waste heat recovery and utilization structure for gas stoves to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waste heat recovery and utilization structure for a gas stove includes a stove platform, a burner core installed inside the stove platform, a control button installed between the burner core and the stove platform, a hot water pot installed on the outside of the stove platform, a bracket groove located on the top of the stove platform around the burner core, a fixing frame installed in the bracket groove, a water guide pipe fixedly connected to the fixing frame, multiple sets of circumferentially distributed pot bottom brackets fixedly connected to the outer wall of the water guide pipe, multiple sets of heat-conducting plates fixedly connected to the outer wall of the water guide pipe between the pot bottom brackets, an installation pipe fixedly connected to the inlet and outlet ends of the water guide pipe, an installation hole provided at the bottom of the bracket groove, a sealing nut threaded through the installation hole of the installation pipe, and a connecting pipe rotatably connected to the sealing nut.

[0007] As a further embodiment of this utility model: a water pump is installed on the outer wall of the hot water pot, and the water pump is connected to a set of connecting pipes through a flexible hose.

[0008] As a further improvement of this utility model: a connector is installed at the bottom of the hot water pot, and the connector is connected to another set of connecting pipes through a flexible hose.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model replaces the traditional pot bottom support with a water pipe installed inside the pot bottom support, and controls the circulation of water between the hot water pot and the water pipe. This recovers excess heat from the stove and transfers it to the water in the hot water pot, thus realizing the recovery and utilization of waste heat from the gas stove. However, due to the heat limitation, the water level in the hot water pot will not be too high. Therefore, the warm water in the hot water pot can be used for cooking, washing pots, etc., but it cannot be drunk directly. Furthermore, this utility model only requires a simple modification to the traditional gas stove, improving the practicality of the equipment. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figures 1-4In this embodiment of the utility model, a waste heat recovery and utilization structure for a gas stove includes a stove platform 1, a furnace core 2 installed inside the stove platform 1, a control button 3 installed on one side of the stove platform 1, a hot water pot 4 installed on the outside of the stove platform 1, a bracket groove 5 located on the top of the stove platform 1 around the furnace core 2, a fixing frame 6 installed in the bracket groove 5, a water guide pipe 7 fixedly connected to the fixing frame 6, multiple sets of pot bottom brackets 8 arranged in a circular pattern fixedly connected to the outer wall of the water guide pipe 7, multiple sets of heat-conducting plates 9 fixedly connected to the outer wall of the water guide pipe 7 between the pot bottom brackets 8, an installation pipe 10 fixedly connected to the water inlet and outlet of the water guide pipe 7, an installation hole 15 provided at the bottom of the bracket groove 5, and a connecting pipe 11 connected to the installation pipe 10 through the installation hole 15. Specifically, the installation pipe 10 and the connecting pipe 11 are rotatably connected by a sealing nut 12.

[0017] During installation, this utility model only requires drilling two sets of mounting holes 15 in the bracket groove 5 of the traditional stove 1, passing the mounting pipe 10 through the mounting holes 15, and then threading the sealing nut 12 to the bottom of the mounting pipe 10. While connecting the connecting pipe 11 and the mounting pipe 10, the stove 1 is clamped and fixed by the cooperation of the sealing nut 12 and the fixing bracket 6, and then the fixing bracket 6 is fixed in the bracket groove 5. Then the connecting pipe 11 can be connected to the hot water pot 4. When the stove 1 is lit, the pot is placed on the bottom bracket 8, thus avoiding contact between the bottom of the pot and the heat-conducting plate 9. When the stove heats the pot, the excess heat is absorbed by the heat-conducting plate 9 and heats the water in the heat-conducting pipe. At the same time, through the circulation between the hot water pot 4 and the water pipe 7, the excess heat from the stove is recovered and transferred to the water in the hot water pot 4, thus realizing the recovery and utilization of the waste heat of the gas stove.

[0018] In one instance of this embodiment, please refer to Figures 1-4 A water pump 13 is installed on the outer wall of the hot water pot 4. The water pump 13 is connected to a set of connecting pipes 11 through a flexible hose. A connector 14 is installed at the bottom of the hot water pot 4. The connector 14 is connected to another set of connecting pipes 11 through a flexible hose.

[0019] This invention uses a water pump 13 to pump the water in the hot water pot 4, thereby enabling the water to circulate between the hot water pot 4 and the water pipe 7.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
