Description

Technical Field

[0001] This utility model relates to the field of food machinery technology, specifically to an intelligent wok. Background Technology

[0002] Woks, as a common cooking device, are widely used in food processing, catering, and pharmaceutical and chemical industries, playing a particularly important role in the stir-frying of sauces, seasonings, and medicinal herbs. Traditional woks typically use open flame heating, with the wok body heated by burners inside the furnace to achieve uniform stir-frying and high-temperature processing of materials.

[0003] However, most existing woks do not have a fully enclosed furnace design. For example, one type of wok used by our company in the early stages had a semi-circular arc-shaped furnace shell 31 at the bottom. Figure 1 As shown, the bottom of the furnace shell 31 is provided with an opening 300, which is used to install the stove 4; however, the heat of this type of wok is easily lost during use, resulting in low thermal efficiency and poor energy saving, which increases the gas cost of enterprises.

[0004] Based on this, our company has improved the existing bottom of the wok and the structure of the furnace body, and designed a fully enclosed furnace body structure, which effectively reduces heat loss, improves energy utilization efficiency, and reduces the gas cost for enterprises. Utility Model Content

[0005] This invention provides an intelligent wok that can solve the technical problem of heat loss and poor energy efficiency caused by the non-enclosed furnace structure at the bottom of the wok during use.

[0006] This application provides the following technical solution:

[0007] A smart wok includes a frame, a wok body mounted on the frame, and a stove body located at the bottom of the wok body. The stove body includes a semi-circular arc-shaped furnace shell and a semi-circular arc-shaped support platform inside the furnace shell, with a stove located at the center of the support platform. The bottom of the wok body has an annular ring for sealing with the support platform, and several smoke vents are provided between the annular ring and the wok body wall. The support platform and the bottom of the wok body form a closed furnace chamber, and the outer walls of the furnace shell and the wok body form a heat preservation cavity. The smoke vents communicate with the heat preservation cavity, and the furnace shell is also provided with a smoke exhaust pipe communicating with the heat preservation cavity.

[0008] Beneficial effects:

[0009] 1. High efficiency and energy saving, reducing heat loss: By setting the furnace body as a double-layer structure, the support platform and the annular ring at the bottom of the pot body are closely matched to form a closed combustion space (first layer), which can effectively prevent heat loss to the outside; at the same time, the heat insulation cavity formed between the furnace shell and the outer wall of the pot body (second layer) further blocks heat radiation and improves the thermal energy utilization rate. Compared with the traditional single-layer, open furnace body structure, this application can significantly reduce energy consumption and reduce enterprise production costs.

[0010] 2. Optimize the exhaust path and improve heat exchange efficiency: The exhaust holes at the bottom of the pot are connected to the insulation cavity, so that the high-temperature flue gas after combustion forms a circulation in the insulation cavity, prolongs the residence time of the flue gas, enhances the heat exchange effect on the pot, and finally the flue gas is discharged through the exhaust pipe, avoiding heat waste. This structure not only improves heating efficiency, but also reduces heat loss caused by direct emission of flue gas.

[0011] 3. Stable structure and reliable safety: The support platform and the bottom of the pot are sealed together by a ring, ensuring the airtightness of the furnace, preventing flame leakage, making combustion more stable, and reducing the possibility of accidental flameout or backfire; in addition, the closed design can reduce the influence of the external environment on the combustion process, which is conducive to improving the precise control of the frying temperature.

[0012] Furthermore, the support platform and the annular ring are sealed with fire-resistant cotton, and the bottom of the support platform is provided with an opening, with the stove installed at the opening and sealed with fire-resistant cotton.

[0013] Beneficial effects: Traditional woks have many gaps between the furnace and the outside, causing a large amount of heat to be lost through radiation and convection; while the double fire-resistant cotton seal of this application (support platform-ring ring, stove-opening) can significantly reduce ineffective heat loss, allowing more heat to be concentrated on heating the wok body and reducing gas consumption.

[0014] Furthermore, a fire observation channel is also provided on the support platform. The inner side of the fire observation channel is connected to the furnace, and the outer side of the fire observation channel is connected to the outside world. A transparent cover is provided at its outer end.

[0015] Beneficial effects: The observation passage connects the furnace to the outside, allowing operators to directly observe the flame combustion in the enclosed furnace and avoid safety hazards caused by abnormal flames; the transparent cover on the outside of the passage can also reduce heat loss from the furnace.

[0016] Furthermore, the stove includes a ring-shaped furnace core, an air inlet pipe, and an igniter. The air inlet pipe is located at the bottom of the stove to supply a mixture of gas and air to the furnace core. The stove also has a cover plate at its center for sealing the furnace chamber.

[0017] Beneficial effects: The cover plate set in the center of the stove can effectively seal the furnace chamber and prevent high-temperature flue gas from escaping from the center of the furnace core, further reducing heat loss; and by setting the cover plate in the center of the stove, compared with setting the furnace core structure directly in the center of the stove, this application can also reduce the problem of the pot burning due to local overheating at the bottom of the pot.

[0018] Furthermore, the furnace core is composed of several corrugated furnace core units arranged at intervals.

[0019] Beneficial effects: The corrugated furnace core unit can generate stronger turbulent combustion, making the flame distribution more uniform, the combustion more complete, reducing gas consumption, and achieving the goal of energy saving.

[0020] Furthermore, several baffles are installed between adjacent furnace core units. The baffles are in an inverted "L" shape, and all the baffles face the center of the stove.

[0021] Beneficial effects: The fire baffle can prevent the flame from spreading laterally, making the combustion more stable and the pot body heated more evenly.

[0022] Furthermore, a flame detector is installed on the stove, and the flame detector is connected to a controller.

[0023] Beneficial effects: Flame detectors can detect whether the gas is burning after ignition, preventing danger caused by the continuous release of unburned gas.

[0024] Furthermore, a safety valve is connected to the intake pipe, and the safety valve is electrically connected to a controller.

[0025] Beneficial effect: When the flame detector does not detect a flame after ignition, it sends a signal to the controller. Upon receiving the signal, the controller controls the safety valve to close, cutting off the continued supply of the gas and air mixture. Attached Figure Description

[0032] The markings in the accompanying drawings of the instruction manual include: frame 1, pot body 2, annular ring 21, smoke vent 210, furnace body 3, furnace shell 31, opening 300, insulation cavity 310, smoke vent pipe 311, support platform 32, furnace chamber 320, observation channel 321, stove 4, furnace core 41, fire baffle 42, igniter 43, flame detector 44, cover plate 45, air inlet pipe 40, safety valve 401, and refractory cotton 5.

[0033] Example

[0034] like Figure 2-4 As shown, a smart wok includes a frame 1, a wok body 2 mounted on the frame 1, and a stove body 3 located at the bottom of the wok body 2. The stove body 3 includes a semi-circular arc-shaped stove shell 31 and a semi-circular arc-shaped support platform 32 disposed within the stove shell 31. A stove 4 is disposed at the center of the support platform 32. Figure 3 As shown, in this embodiment, the bottom of the pot body 2 is provided with an annular ring 21 for sealing with the support platform 32, and a plurality of smoke exhaust holes 210 are provided between the inner side of the annular ring 21 and the pot body wall. Figure 2 As shown, in this embodiment, the support platform 32 and the bottom of the pot body 2 form a closed furnace 320, the furnace shell 31 and the outer wall of the pot body 2 form a heat preservation cavity 310, the smoke exhaust hole 210 is connected to the heat preservation cavity 310, and the furnace shell 31 is provided with a smoke exhaust pipe 311 that is connected to the heat preservation cavity 310.

[0035] Specific examples Figure 4 As shown, the support platform 32 and the annular ring 21 are sealed with refractory cotton 5. The bottom of the support platform 32 and the furnace shell 31 is provided with an opening 300. The stove 4 is located at the opening 300, and the gap between the stove 4 and the opening 300 is also sealed with refractory cotton 5 to reduce heat loss.

[0036] In this embodiment, the furnace body 3 is configured as a double-layer structure. The support platform 32 is tightly fitted with the annular ring 21 at the bottom of the pot body 2 to form a closed combustion space (first layer), which can effectively prevent heat loss. At the same time, the heat insulation cavity 310 (second layer) formed between the furnace shell 31 and the outer wall of the pot body 2 further blocks heat radiation and improves the thermal energy utilization rate. Compared with the traditional single-layer, open furnace body 3 structure, this application can significantly reduce energy consumption and reduce the gas cost of enterprises.

[0037] In addition, by connecting the exhaust port 210 at the bottom of the pot body 2 with the heat preservation cavity 310, the high-temperature flue gas after combustion forms a circulation in the heat preservation cavity 310, prolonging the residence time of the flue gas and enhancing the heat exchange effect on the pot body 2. Finally, the flue gas is discharged through the exhaust pipe 311, avoiding heat waste. This structure not only improves the heating efficiency, but also reduces the heat loss caused by the direct emission of flue gas.

[0038] like Figure 4As shown, a fire observation channel 321 is also provided on the support platform 32. An observation tube extending outward is provided on the fire observation channel 321, so that the inner side of the fire observation channel 321 is connected to the furnace 320 and the outer side of the fire observation channel 321 is connected to the outside. A transparent cover (not shown in the figure) is provided at the outer end of the observation tube. The fire observation channel 321 connects the furnace 320 with the outside, so that the operator can directly observe the flame combustion of the closed furnace 320 and avoid safety hazards caused by abnormal flame. The transparent cover on the outside of the channel can also reduce the heat leakage of the furnace 320.

[0039] like Figure 5 As shown, the stove 4 includes a ring-shaped furnace core 41, an air inlet pipe 40, and an igniter 43. The air inlet pipe 40 is located at the bottom of the stove 4 to supply a mixture of gas and air to the furnace core 41. In this embodiment, a cover plate 45 for sealing the furnace chamber 320 is also provided at the center of the stove 4. The cover plate 45 can effectively seal the furnace chamber 320, prevent high-temperature flue gas from escaping from the center of the furnace core 41, and further reduce heat loss. Moreover, by setting the cover plate 45 at the center of the stove 4, compared with setting the furnace core 41 structure directly at the center of the stove 4, this application can also reduce the problem of scorching caused by local overheating at the bottom of the pot 2.

[0040] The furnace core 41 is composed of several corrugated furnace core units arranged at intervals. The corrugated furnace core units can form a stronger turbulent combustion, making the flame distribution more uniform and the combustion more complete, which can effectively reduce gas consumption and achieve the purpose of energy saving. More preferably, several baffle plates 42 are also provided between adjacent furnace core units. The baffle plates 42 are in the shape of an inverted "L" and are located on the outside of the furnace core 41. The horizontal plate of the inverted "L" is higher than the furnace core 41 unit and is set towards the center of the stove 4.

[0041] More preferably, in this embodiment, the stove 4 is also equipped with a flame detector 44, which is connected to a controller; a safety valve 401 is connected to the air inlet pipe 40, and the safety valve 401 is also electrically connected to the controller; the flame detector 44 is used to detect whether the gas is in a combustion state after ignition. When the flame detector 44 does not detect a flame after ignition, it sends a signal to the controller. After receiving the signal, the controller controls the safety valve 401 to close, thereby cutting off the continued delivery of the gas and air mixture, so as to realize intelligent control and improve the safety of use.

[0042] It is worth noting that the double-layer furnace body 3 structure provided in this application can be set at the bottom of any existing wok, including but not limited to existing smart woks, such as the self-tilting stirring wok provided by CN207996146U, which has an automatic stirring mechanism. This embodiment mainly improves the furnace body 3 structure at the bottom of various existing woks. The structure of different types of woks will not be described in detail here.

Commonly known structures and characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
