Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 6 , in the embodiments of the present invention, an energy-saving integrated stove includes an integrated stove body 10, an insulation box 20, a bottom pot support 60 and a circulation assembly 80. The top of the integrated stove body 10 is connected to a stove top body 30 through an insulation box 20 filled with water inside. Two groups of storage cabinets 40 are symmetrically installed inside the insulation box 20. Pull-out assemblies 50 are slidably installed inside both groups of storage cabinets 40. Two groups of bottom pot supports 60 are symmetrically installed on the top of the stove top body 30. The inside of the stove top body 30 is connected to two burner heads 11 extending to the center of the bottom pot support 60 through an air supply assembly 70. The circulation assembly 80 fixedly installed inside the stove top body 30 winds around the inner circles of the two bottom pot supports 60, and both ends of the circulation assembly 80 extend into the inner cavity of the insulation box 20.

[0027] The stove body 30 includes the necessary structures such as the igniter, control valve, battery, etc. in the prior art. The air supply assembly 70 also includes the necessary structures such as the air intake pipe, air distribution pipe and ejection pipe in the prior art. The structure and connection method are all prior art and will not be repeated here. When the food insulation function of the energy-saving integrated stove is needed, the stove body 30 ignites the flame at the center of the pot bottom bracket 60 to heat the pot body and other components. The pot bottom bracket 60 can effectively reduce the external natural wind or range hood wind on the fire The circulation component 80 is started when the stove body 30 is in use to avoid the influence of the flame. The stove body 30 can heat the circulation component 80 part of the center of the pot bottom bracket 60 simultaneously. The circulation component 80 circulates and pumps the liquid inside the heat preservation box 20 to steadily heat the heat preservation box 20. The user can place the prepared dishes on the pull-out component 50 inside the storage cabinet 40 for storage. The heat preservation box 20 heated by the flame of the gas stove can effectively keep the dishes warm and is not easy to evaporate the moisture of the dishes.

[0028] When the integrated stove does not need the insulation function in daily use, the internal components of the circulation component 80 can also block the heat generated by the stove body 30 from being transmitted to the insulation box 20. The pull-out component 50 inside the storage cabinet 40 can be used to store components such as kitchen utensils. When the circulation component 80 is needed to quickly cool down the stove body 30, the insulation function of the device is idle. The liquid inside the insulation box 20 is at room temperature. The circulation component 80 is started to circulate and pump the liquid inside the insulation box 20. The circulation component 80 drives the room temperature liquid to circulate inside the stove body 30 and the pot bottom bracket 60, which can quickly take away the heat around the components to achieve rapid heat dissipation of the device. A commonly used oven can be assembled under the integrated stove body 10. When the oven is in use, the insulation box 20 with water inside can prevent the heat of the oven from being transmitted to the upper stove body 30 and other firmware, which is beneficial to improving the actual service life of the stove body 30.

[0029] See also Figures 1 to 4 Furthermore, a partition box 12 is sandwiched between the insulation box 20 and the stove body 30, and a heat insulation box 13 is installed on the front of the insulation box 20. The partition box 12 and the heat insulation box 13 can effectively prevent the front of the device or the stove body 30 from overheating when the integrated stove insulation function is used.

[0030] In one embodiment, see Figures 2 to 6, Specifically, the circulation component 80 includes a circulation pump body 801 fixedly installed inside the partition box 12. One end of the circulation pump body 801 is communicated with a water suction pipe 802 extending to the bottom of the inner cavity of the heat preservation box 20. The other end of the circulation pump body 801 is communicated with a first branch pipe 803. Both ends of the first branch pipe 803 are communicated with spiral heat collecting pipes 804 coiled around the inner circle of the pot bottom bracket 60. The ends of the two groups of heat collecting pipes 804 are communicated with a second branch pipe 805. The bottom end of the second branch pipe 805 is communicated with a water outlet pipe 806 extending to the top of the inner cavity of the heat preservation box 20.

[0031] Start the circulation pump body 801. The circulation pump body 801 uses the water suction pipe 802 to extract the liquid at the bottom of the inner cavity of the heat preservation box 20. The circulation pump body 801 pumps the liquid into the interiors of the two groups of spiral heat collecting pipes 804 through the first branch pipe 803 for heating and circulating flow. After one cycle of heating, the liquid is transported to the second branch pipe 805. The liquid inside the second branch pipe 805 flows back into the interior of the heat preservation box 20 through the water outlet pipe 806, which can stably increase the temperature of the heat preservation box 20. While improving the use function of the integrated stove, it is also conducive to efficiently utilizing the heat generated during the use of the gas stove, and is more conducive to the energy conservation and environmental protection of the device.

[0032] Furthermore, first solenoid valves 14 are installed near the two groups of pot bottom brackets 60 on the first branch pipe 803, and second solenoid valves 15 are installed near the two groups of pot bottom brackets 60 on the second branch pipe 805. When the circulation pump body 801 is running, both the first solenoid valve 14 and the second solenoid valve 15 are opened to make the liquid inside the circulation component 80 circulate. When the circulation pump body 801 is closed, both the first solenoid valve 14 and the second solenoid valve 15 are closed, which can prevent the heat generated during the daily use of the gas stove from quickly conducting to the inside of the stove body 30 and the heat preservation box 20, improving the flexibility of the actual use of the device. The circuit connections of the solenoid valves and the pump body to the total controller and the control panel of the device are all prior arts and will not be elaborated here.

[0033] Based on the above embodiments, refer to Figures 1 to 6 , Specifically, the pot bottom bracket 60 includes a support ring 601 fixedly connected to the stove body 30. A shielding ring 602 for supporting the heat collecting pipe 804 inside the inner circle is welded on the top of the support ring 601. The ends of the first branch pipe 803 and the second branch pipe 805 both pass through the support ring 601 and the shielding ring 602 and are communicated with the ends of the heat collecting pipe 804. A plurality of first ventilation holes 603 are opened in the inner circle of the shielding ring 602, and a plurality of second ventilation holes 604 are opened in the outer circle of the shielding ring 602.

[0034] Correspondingly, multiple groups of bent support rods 16 for supporting the bottom of the pot are welded on the heat collecting pipe 804, and the multiple groups of bent support rods 16 are arranged at equal circumferential intervals around the central axis of the shielding ring 602. The inner ring of the shielding ring 602 is communicated with the outside through the first ventilation holes 603 and the second ventilation holes 604. When the burner 11 is ignited and used, the shielding ring 602 can effectively prevent the gas stove flame from being affected by the external environment during use. The flame on the burner 11 is concentrated at the bottom of the pot, which can efficiently utilize the heat generated by the combustion of the gas. The provided first ventilation holes 603 and second ventilation holes 604 can transport external oxygen to the shielding ring 602 to ensure the full combustion and utilization of natural gas. The multiple groups of bent support rods 16 can cause the flame to spread to the outer ring at the top of the shielding ring 602, which is beneficial to ensuring the actual contact area between the flame and the bottom of the pot.

[0035] Among them, the inner ring of the shielding ring 602 is funnel-shaped, and multiple groups of first ventilation holes 603 opened on the inner ring of the shielding ring 602 are evenly distributed between the spiral heat collecting pipes 804. The outer ring of the shielding ring 602 is cylindrical, and multiple groups of second ventilation holes 604 inclined in the direction of the first ventilation holes 603 are opened on the outer ring of the shielding ring 602. The spiral heat collecting pipe 804 coiled around the inner ring of the funnel-shaped shielding ring 602 can enable the flame to fully heat the spiral heat collecting pipe 804 and the liquid inside it, ensuring the efficient use of the heat preservation function of the integrated stove. At the same time, the correspondingly arranged first ventilation holes 603 and second ventilation holes 604 can prevent the flame from diffusing from the side to the outside of the shielding ring 602, and can also enable the external air to efficiently rush into the inside of the shielding ring 602 to fully combust the natural gas.

[0036] In one embodiment, referring to Figures 1 to 3 , specifically, the pulling component 50 includes a placement box 501 slidably installed inside the storage cabinet 40. A push-pull plate 502 is connected to the front end of the placement box 501. Multiple groups of equally spaced card slots 503 are opened on both sides of the inner ring of the placement box 501. A partition plate 504 is snap-fitted inside two of the card slots 503. The provided multiple groups of card slots 503 and the partition plate 504 facilitate adjusting the accommodation space inside the placement box 501, and facilitate the staff to flexibly place cooking utensils, tableware, etc. of different sizes inside the placement box 501. The water temperature rise inside the incubator 20 can heat the storage cabinet 40, and the heated storage cabinet 40 can keep warm the dishes and the like placed inside it.

[0037] Two groups of front-rear corresponding liquid level observation windows 17 are provided on the front of both the incubator 20 and the heat insulation box 13, which is convenient for observing the changes in the liquid inside the incubator 20 and facilitating the operator to discover in time when the incubator 20 leaks. A vertical pipe 18 communicating with the inner cavity of the incubator 20 is fixedly installed at a corner of the partition box 12 and the stove body 30. The top of the vertical pipe 18 is detachably connected with a sealing cover 19 by threads, which is convenient for replenishing liquid or changing liquid inside the incubator 20.
