[0023] The following is combined with Figure 1 To Attachment Figure 3 The utility model is further described in detail with reference to specific embodiments.

[0024] One embodiment discloses a water-cooled anti-scalding cooking stove, which is used to solve the problem that the cooking environment is unbearable or even scalds the human body due to the increase in temperature of the stove top 12 and the stove body.

[0025] In the present embodiment, the water-cooled anti-scalding cooking stove includes a stove body 10, a stove top 12 installed on the stove body 10, a furnace 11 arranged in the stove body 10, and a water-cooled insulation component 20. A convex edge extending upward is provided at the connection between the stove body 10 and the stove top 12, and the convex edge and the upper surface of the stove top 12 form a groove body; the water-cooled insulation component 20 includes a water tank 21 arranged on one side of the upper part of the stove top 12, and a cooling water bladder 23 arranged around the outer side of the furnace 11 and between the furnace 11 and the stove body 10. The water tank 21 and the cooling water bladder 23 are connected by a water supply pipeline, and the water supply pipeline is provided with a water replenishment valve 211 for replenishing cooling water into the cooling water bladder 23 in real time.

[0026] When using the above-mentioned water-cooled anti-scalding cooking stove, first ensure that sufficient cooling water is filled in the water tank 21. After the furnace 11 is ignited, as the external temperature of the stove body 10 increases, the water supply valve 211 is opened to allow cooling water to flow into the cooling water tank 23, and a certain amount of cooling water is poured into the groove formed by the convex edge and the surface of the stove 12, and the cooling water liquid level is not higher than the convex edge height.

[0027] The cooling water tank 23 is connected to a return water pipeline, and a second return water pump 33 is provided in the return water pipeline for recycling the water in the cooling water tank 23 .

[0028] When using the above-mentioned water-cooled anti-scalding cooking stove with water-cooled insulation component 20, at least the following effects are achieved: when the furnace 11 is ignited, the heat radiated to the outside of the furnace 11 can be absorbed by the cooling water in the cooling water tank 23, which can prevent the stove body 10 from conducting a large amount of heat to the cooking space; the cooling water in the groove formed by the stove top 12 and the convex edge can absorb the heat transferred from the furnace 11 to the stove top 12, preventing the stove top 12 from being too hot and scalding the human body.

[0029] As some preferred implementations of this embodiment, the structure or function of the above-mentioned water-cooled anti-scalding cooking stove is further explained. Embodiment 1

[0030] Furthermore, the water-cooled insulation component 20 also includes an insulation interlayer 22 , which surrounds the outer side of the furnace 11 and is arranged between the furnace 11 and the cooling water tank 23 , and the insulation interlayer 22 is used to be filled with insulation medium.

[0031] Specifically, the insulating interlayer 22 can be the gap between the outer side of the furnace 11 and the inner side of the cooling water tank 23, and the gap is used to fill the insulating medium; it can also be a sleeve-shaped component made of solid material with a certain filling space, the sleeve-shaped component is sleeved between the furnace 11, and the filling space of the sleeve-shaped component is filled with the insulating medium; the above-mentioned insulating media are all materials with insulating properties other than water, such as ceramic fiber, graphite, refractory clay, refractory bricks, etc.

[0032] The heat-insulating interlayer 22 can be used to keep the temperature in the middle and upper parts of the furnace 11 within the temperature range required for cooking food, so as to ensure that the bottom and sides of the pot placed above the furnace 11 can be evenly heated, thereby improving the cooking efficiency; and because the heat-insulating medium and the heat-insulating interlayer 22 have a certain heat-insulating effect on the furnace 11, the cooling water in the cooling water tank 23 can be prevented from boiling quickly, so that the temperature of the outer surface of the stove body 10 is not easy to reach a value that can scald the human body.

[0033] Furthermore, in the vertical direction, the thickness of the thermal insulation interlayer 22 gradually decreases from top to bottom.

[0034] Specifically, since the temperature from the middle to the upper part of the furnace 11 is different, and the temperature in the middle mainly heats the bottom of the pot, and the temperature in the upper part heats the side of the pot, the thick upper and thin lower insulating interlayer 22 can make the efficiency of transferring temperature from the furnace 11 to the cooling water tank 23 gradually decrease from bottom to top, thereby reducing the temperature difference between the side and bottom of the pot, making the pot heated evenly and ensuring cooking efficiency.

[0035] Furthermore, any longitudinal cross section of the heat insulating interlayer 22 from top to bottom is in the shape of an inverted truncated cone.

[0036] Specifically, the inverted truncated cone-shaped heat insulating interlayer 22 can ensure that the sides of the pot and the ground are heated evenly, while evenly transferring the excess heat in the furnace 11 to the cooling water tank 23 to prevent the furnace 11 from being overheated and damaged.

[0037] The difference between the second embodiment and the first embodiment is that:

[0038] The side of the heat insulating interlayer 22 facing away from the furnace 11 is stepped from top to bottom.

[0039] Specifically, the heat-insulating interlayer 22 is in the shape of three steps from top to bottom, and each step corresponds to the upper, middle and lower parts of the furnace 11 and performs segmented insulation on the upper, middle and lower parts of the furnace 11. Since the thickness change rate of the heat-insulating interlayer 22 from top to bottom is greater in Example 2, the upper, middle and lower layers of the heat-insulating interlayer 22 can be filled with heat-insulating media of different thicknesses respectively. Therefore, the upper part of the heat-insulating interlayer 22 has a larger sensible heat storage capacity, which can further improve the degree of obstruction to the radiation of the upper temperature of the furnace 11 to the cooling water tank 23, thereby ensuring that the sides and bottom of the pot are heated evenly.

[0040] Further improvement based on any of the above embodiments:

[0041] A plurality of vents 13 are disposed on the outside of the stove body 10 , and a heat dissipation cavity 14 is formed between the inside of the stove body 10 and the cooling water tank 23 , and the heat dissipation cavity 14 is communicated with the vents 13 .

[0042] As the temperature of the furnace 11 continues to rise, part of the heat that exceeds the heat storage capacity of the insulation interlayer 22 will be absorbed by the cooling water in the cooling water tank 23. In order to prevent the temperature of the cooling water tank 23 from rising and causing the water to boil, the vents 13 and the heat dissipation cavity 14 can play a certain cooling role on the cooling water tank 23.

[0043] Furthermore, there are two ventilation holes 13, which are respectively arranged on opposite sides of the stove body 10. A fan 131 is installed in one of the ventilation holes 13, and the fan 131 is used to blow air into the heat dissipation cavity 14; the other ventilation hole 13 is connected to a ventilation duct 132, which is used to guide the hot air in the heat dissipation cavity 14 to the outside.

[0044] Specifically, one end of the ventilation duct 132 can be connected to the outdoors to guide the hot air flow in the heat dissipation cavity 14 to the outdoors, making the indoor cooking environment more comfortable.

[0045] Furthermore, a plurality of guide fins 141 are provided at intervals on the side wall of the heat dissipation cavity 14 along the ventilation direction.

[0046] Specifically, guide heat sinks 141 are arranged at intervals on the outer wall of the cooling water tank 23 or the inner wall of the stove body 10, or the guide heat sinks 141 are arranged at intervals and interspersed on the outer wall of the cooling water tank 23 and the inner wall of the stove body 10, with the purpose of increasing the contact area between the heat dissipation cavity 14 and the cooling air, extending the flow time of the cooling air in the heat dissipation cavity 14, and improving the cooling efficiency of the cooling water tank 23.

[0047] When the water-cooled anti-scalding cooking stove is used continuously, the speed of the water temperature increase in the cooling water tank 23 is first slowed down by the air cooling effect. Even if the water temperature rises to a critical value under the air cooling effect, it is only necessary to start the second return water pump 33 to make the spare cooling water in the water tank 21 and the water in the cooling water tank 23 to perform convection circulation, which can further reduce the water temperature and reduce the consumption of cooling water.

[0048] Furthermore, a water outlet valve 212 is installed on one side of the water tank 21, and the water outlet valve 212 is used to release the cooling water in the water tank 21 into the groove formed by the surface of the stove top 12 and the convex edge of the stove body 10; a confluence groove 15 is provided on the side of the stove top 12 away from the water outlet valve 212, and a drain outlet 151 is provided at the bottom of the confluence groove 15.

[0049] When using the water-cooled anti-scalding cooking stove, the water outlet valve 212 is opened to pour water on the stove top 12 to cool and rinse the stove top 12. The confluence groove 15 is used to collect the rinsing water on the surface of the stove top 12. When the rinsing water is contaminated by oil, it can flow away through the drain port 151 to ensure that the stove top 12 is clean.

[0050] Furthermore, the water-cooled anti-scalding cooking stove also includes a cooling water recovery component 30, which includes an oil-water separator 31 and a first return water pump 32. The oil-water separator 31 includes a box body, and a water inlet and a clean water outlet are arranged on opposite sides of the box body. Filter residue grooves and multiple partitions are arranged in sequence in the box body along the direction of water flow in and out, and the partitions are respectively connected to the bottom or top of the box body. An overflow gap is arranged between the partitions and the box body, and a space for separating oil and water is formed between the partitions. The water inlet of the oil-water separator 31 is connected to the drain 151 through a pipeline, the clean water outlet of the oil-water separator 31 is connected to the water inlet of the first return water pump 32, and the water outlet of the first return water pump 32 is connected to the water tank 21 through a pipeline.

[0051] Specifically, the oil-water separator 31 suppresses the flow rate of water through the space formed by multiple partitions, and uses the density difference between water and oil and the potential energy of water to make the water in the lower layer of the space on the front side of the box flow to the rear side of the box. The oil on the water surface is adsorbed and blocked by the partitions at each level, so that the oil content of the water finally flowing out from the clean water outlet is lower than that of the water before flowing into the oil-water separator 31.

[0052] When the water-cooled anti-scalding cooking stove is used, the first water return pump 32 is started to return the cooling water after oil removal by the oil-water separator 31 to the water tank 21 for recycling, thereby reducing the loss of cooling water.

[0053] Furthermore, the cooling water recovery component 30 further includes a second return water pump 33 , a water inlet of the second return water pump 33 is connected to the cooling water tank 23 , and a water outlet of the second return water pump 33 is connected to the water tank 21 .

[0054] Specifically, the water tank 21 is connected to the cooling water tank 23 through a return water pipeline, and a second return water pump 33 is connected to the return water pipeline, so that the water in the cooling water tank 23 can circulate with the water tank 21. A steam escape port 213 is also provided on the top of the water tank 21 to volatilize the hot water returning into the water tank 21 to prevent the water tank 21 from having too high a pressure.

[0055] Through the above implementation, at least the following technical effects are achieved:

[0056] When the furnace 11 is ignited, the heat radiated to the outside of the furnace 11 can be absorbed by the cooling water in the cooling water tank 23, which can prevent the stove body 10 from transferring a large amount of heat to the cooking space; the cooling water on the stove top 12 can absorb the heat transferred from the furnace 11 to the stove top 12, preventing the stove top 12 from being overheated and scalding the human body; the heat insulating interlayer 22 and the heat insulating medium located on the outside of the furnace 11 can prevent the heat in the furnace 11 from being quickly absorbed by the cooling water tank 23, so that the temperature of the middle and upper parts of the furnace 11 can be maintained within the temperature range required for cooking food, so as to ensure that the bottom and sides of the pot placed above the furnace 11 can be evenly heated, thereby improving the cooking efficiency; when the water-cooled anti-scalding cooking stove is used for a long time, the speed of the water temperature increase in the cooling water tank 23 is first slowed down by the air cooling effect. Even if the water temperature rises to the critical value under the air cooling effect, it is only necessary to start the second return water pump 33 to make the standby cooling water in the water tank 21 and the water in the cooling water tank 23 circulate by convection, which can further reduce the water temperature and reduce the consumption of cooling water.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
