Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen utensils, and in particular relates to a cooking utensil with rapid heat dissipation. Background Art

[0002] Existing cooking utensils, such as electric rice cookers and pressure cookers, generally include a pot body and a pot cover. The pot body is provided with an inner pot and a heating device for heating the inner pot. The inner pot is generally made of metal. When the heating device is powered on, it can transfer heat to the inner pot to cook the rice in the inner pot. However, such cooking utensils may stick to the pot during the cooking process, making it difficult to clean the inner pot after the meal, which deteriorates the user experience.

[0003] In order to solve this technical problem, the applicant has previously applied for a water-moisturizing film coating technology. By setting a cooling fan on the pot body, the cooling fan operates to form a flowing airflow to cool the inner pot, so that when the high-temperature steam inside the inner pot contacts the inner pot, it will quickly condense and liquefy into condensed water to form a layer of water film between the food and the inner wall of the inner pot, preventing the food from sticking to the inner wall of the inner pot, and achieving a non-stick effect. When the heating device uses a heating plate, since the heating plate will accumulate a large amount of heat, it will continuously transfer heat to the inner pot, resulting in the inner pot being unable to cool down quickly, causing the final non-stick effect to be slightly worse than the solution using an IH coil plate as the heating device. Therefore, the applicant continued to study and produced the technical solution of the utility model, which further improved the effect of the cooking utensils producing a water-moistening film and achieving a non-stick effect when the heating device is a heating plate.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0031] refer to Figure 1 , Figure 6 and Figure 7The present embodiment provides a cooking utensil for rapid heat dissipation, comprising a pot body assembly and a pot cover (not shown in the figure) disposed on the pot body assembly, wherein the pot body assembly comprises a heat preservation cover 100, an inner pot 200 disposed in the heat preservation cover 100, and a heating plate 300 disposed between the heat preservation cover 100 and the inner pot 200, wherein the pot body assembly further comprises a wind shielding plate 400 and a heat dissipation fan 500, wherein the wind shielding plate 400 is disposed in the heat preservation cover 100 and encloses a heat dissipation cavity 900 between the heat preservation cover 100 and the inner pot 200, wherein the heat dissipation plate 300 is at least partially disposed in the heat dissipation cavity 900, and an air inlet end or an air outlet end of the heat dissipation fan 500 is connected to the heat dissipation cavity 900 to promote the circulation of airflow inside and outside the heat dissipation cavity 900. The term "at least partially disposed in the heat dissipation cavity" may refer to the heat dissipation plate being partially disposed in the heat dissipation cavity, such as a heat pipe on the bottom surface or thereon, or the heat dissipation plate being entirely disposed in the heat dissipation cavity, which is not limited here.

[0032] Specifically, the heat preservation cover 100 has an open top and a cylindrical accommodation space, a heating plate 300 is provided at the bottom of the accommodation space, and the inner pot 200 is placed on the heating plate 300, and there is a gap between the inner pot and the inner wall of the heat preservation cover 100, so that the inner pot can be freely placed in or taken out of the accommodation space. The inner pot 200 is used to hold materials to be heated, such as rice, soup and other ingredients. When cooking, the heating plate 300 converts electrical energy into thermal energy and transfers the heat to the inner pot, thereby heating the ingredients in the inner pot 200.

[0033] In this embodiment, a windshield panel 400 is provided to enclose and separate a heat dissipation cavity 900 in the gap between the heat-insulating cover 100 and the inner liner 200, and the heating plate 300 is at least partially located in the heat dissipation cavity 900, so that the airflow formed by the operation of the heat dissipation fan 500 can be concentrated in the heat dissipation cavity 900, and the heating plate 300 can be centrally cooled, so that the temperature of the heating plate 300 can be quickly reduced, and the heating plate 300 can be quickly dissipated, thereby eliminating the heat storage source, avoiding continuous transfer of heat to the inner liner 200, resulting in continuous high temperature in the lower part of the inner liner and making the rice sticky, and at the same time, the lower part of the inner liner can be quickly cooled down, so that a temperature difference is generated between the inner and outer walls of the inner liner above the heating plate 300, which is conducive to the liquefaction of water vapor in the gap of the rice and adheres to the inner wall of the inner liner to form a water film, thereby reducing the adhesion between the rice and the inner liner, and thus improving the non-stick performance of the inner liner.

[0034] It should be noted that the cooling fan 500 can be an air suction fan, that is, the air outlet end of the cooling fan 500 is connected to the cooling chamber 900, and the cooling fan 500 draws cold air from the outside and blows it to the cooling chamber 900; the cooling fan 500 can also be an exhaust fan, that is, the air intake end of the cooling fan 500 is connected to the cooling chamber 900, and the cooling fan 500 extracts the air in the cooling chamber 900 and discharges it to the outside. The utility model does not make specific limitations on this.

[0035] In some embodiments of the present invention, reference Figure 2 and Figure 6 The wind shield plate 400 is disposed between the heating plate 300 and the heat preservation cover 100 , and the wind shield plate 400 , the heating plate 300 , and the heat preservation cover 100 together form the heat dissipation cavity 900 , or the wind shield plate 400 and the heating plate 300 together form the heat dissipation cavity 900 .

[0036] In a specific embodiment, referring to Figure 2 The heating plate 300 includes a plate body 310 and a heating tube 320 fixed on the plate body 310 , and the windshield enclosure 400 includes an outer plate 410 arranged on the outer periphery of the heating tube 320 , and the upper end of the outer plate 410 extends toward the plate body 310 , and the upper end of the outer plate 310 abuts against the plate body 310 .

[0037] Such an arrangement can ensure that the portion of the heating tube with the highest heat is located in the formed heat dissipation cavity, and by abutting the upper end of the outer plate 410 against the disk body 310, the formed heat dissipation cavity can be made relatively closed, and the airflow in the heat dissipation cavity can be made more concentrated, so that the disk body 310 and the heating tube 320 of the heating disk can be fully contact-cooled, thereby more efficiently taking away the heat of the heating disk and improving the heat dissipation effect of the heating disk.

[0038] The disk body 310 may be in the shape of a flat plate, or may be in the shape of a shallow concave with the edge extending outward and upward (see Figure 2 ), thereby having a larger heat transfer area with the inner tank 200; the heating pipe 320 can be fixed to the bottom of the disk body 310 and partially exposed to facilitate heat dissipation, or it can be fully embedded in the disk body 310. Those skilled in the art can make a choice based on actual conditions.

[0039] Better, reference Figure 2 The edge of the plate 310 is provided with a downwardly bent flange, and there is a certain gap between the flange and the arc-shaped plate, and the upper end of the outer plate 410 is inserted into the gap. In this way, on the one hand, the outer plate 410 can be positioned, and on the other hand, the windshield 400 can be hidden through the plate 310, so that the user cannot touch the windshield when taking the inner tank, thereby improving the user experience. It is understandable that the upper end of the outer plate 410 can also abut against other positions of the plate 310, as long as it is located at the periphery of the heating tube 320.

[0040] Of course, the upper end of the outer plate 410 may not completely abut against the disk body 310, but form a flow opening between the disk body 310. The flow opening may be a gap between the wind shielding plate 400 and the heating disk 300, or may be a notch provided on the wind shielding plate 400. In this way, the formed flow opening is closer to the heating disk, so that the airflow can not only cool the heating disk 300 in the heat dissipation cavity, but also cool the heating disk when flowing into or out of the heat dissipation cavity, thereby ensuring the heat dissipation effect.

[0041] In a specific embodiment, referring to Figure 2 and Figure 3 A temperature measuring hole 330 is provided in the middle of the heating plate 300, and the windshield plate 400 includes an inner plate 420 arranged on the outer periphery of the temperature measuring hole 330, and the upper end of the inner plate 420 extends toward the temperature measuring hole 330, and the upper end of the inner plate 420 abuts against the heating plate 300.

[0042] There is generally a gap between the temperature measuring hole 330 and the temperature measuring element inserted therein. By setting an inner enclosure plate 420 and making the upper end of the inner enclosure plate 420 abut against the heating plate 300, the heat dissipation cavity formed can be made relatively closed, and the airflow in the heat dissipation cavity can be made more concentrated, thereby preventing the airflow from flowing directly to the temperature measuring hole and out of the gap without fully contacting the heating plate. At the same time, the temperature measuring hole 330 is generally located on the inner side of the heating tube 320. Such a setting can make the heating tube located in the formed heat dissipation cavity, thereby improving the heat dissipation effect.

[0043] Optional, reference Figure 4 The upper end of the inner panel 420 is provided with a flange, and the inner panel 420 abuts against the plate body 310 of the heating plate through the flange.

[0044] Of course, in some alternative embodiments, the upper end of the inner panel 420 may also form a flow opening with the heating plate 300, which is not limited here, and those skilled in the art may make a selection according to actual conditions.

[0045] In a specific embodiment, referring to Figure 4 The windshield panel 400 includes an outer panel 410, an inner panel 420, and a main body 401 connecting the outer panel 410, the inner panel 420, the main body 401, and the space between the outer panel 410, the inner panel 420, the main body 401, and the heating plate 300 is a heat dissipation cavity 900, that is, the heat dissipation cavity 900 is enclosed by the windshield panel 400 and the heating plate 300. In this way, the outer panel 410, the inner panel 420, and the main body 401 form a whole, and there is no need to assemble the outer panel 410 and the inner panel 420 separately, so that the assembly of the windshield panel 400 is more convenient, thereby improving production efficiency.

[0046] Furthermore, the windshield panel 400 is made of metal such as stainless steel, which is convenient for processing and molding, and also has high temperature resistance, so that the windshield panel 400 can be placed close to a high-temperature heating plate.

[0047] It is understandable that the main body 401 may not be provided, and one end of the windshield plate 400 (for example, the outer plate 410 and / or the inner plate 420) is fixed to one of the heating plate and the thermal insulation cover, and the other end abuts against the other of the two or forms a flow opening between the other of the two, and the space between the outer plate 410, the thermal insulation cover 100, the inner plate 420 and the heating plate 300 is the heat dissipation cavity 900, that is, the windshield plate 400, the heating plate 300 and the thermal insulation cover 100 enclose the heat dissipation cavity 900, which is not limited here.

[0048] In a specific embodiment, referring to Figure 6 The windshield 400 includes a flange 430 arranged around the heating plate 300, one end of the flange 430 is fixed to one of the heating plate 300 and the heat preservation cover 100, and the other end is in contact with the other of the two or forms a flow opening between the other of the two. In this way, the space between the heat preservation cover 100, the flange 430 and the heating plate 300 is a heat dissipation cavity 900, that is, the windshield 400, the heating plate 300 and the heat preservation cover 100 enclose the heat dissipation cavity 900.

[0049] Optionally, the flange is a frill protruding inwardly on the side of the heat preservation cover 100, which extends horizontally or obliquely toward the heating plate 300. Of course, the flange can also be a horizontal plate welded or clamped on the heat preservation cover 100 or the heating plate 300, which is not limited here.

[0050] Optionally, in this embodiment, on the basis of setting the flange 430, an inner panel 420 can also be set, and the space between the flange 430, the heat preservation cover 100, the inner panel 420 and the heating plate 300 is the heat dissipation cavity 900, making the heat dissipation cavity more closed.

[0051] In some embodiments of the present invention, one end of the windshield panel 400 is fixed to one of the heat preservation cover 100 and the inner liner 200, and the other end abuts against the other one or forms a flow opening with the other one.

[0052] This arrangement ensures that the heat dissipation cavity includes the heating plate, and also allows part of the inner pot to be located in the heat dissipation cavity, so that the heat dissipation fan 500 can cool the inner pot while cooling the heating plate 300, so that the temperature at the bottom of the inner pot can be reduced more quickly, thereby further reducing the probability of rice sticking and improving the non-stick performance of the inner pot.

[0053] In a specific embodiment, referring to Figure 7 The windshield panel 400 is a horizontal panel disposed between the inner liner 200 and the heat preservation cover 300, and a heat dissipation cavity 900 is formed between the lower surface of the horizontal panel, the outer surface of the inner liner, and the inner surface of the heat preservation cover. The horizontal panel can be integrally formed with the heat preservation cover 100 or the inner liner 200, or can be fixed to one of the heat preservation cover 100 or the heating plate 300 by connection or clamping, etc., which is not limited here.

[0054] In another specific embodiment, similar to Figure 2 The windshield panel 400 includes an outer panel 410, an inner panel 420 and a main body 401 connecting the two. The main body 401 is located between the heat preservation cover 100 and the heating plate 300. The outer panel 410 extends upward to the outer surface of the inner liner 200. In this way, a heat dissipation cavity 900 is formed between the windshield panel and the outer surface of the inner liner.

[0055] In some embodiments of the present invention, reference Figure 2 and Figure 3 The side of the heat preservation cover 100 is provided with a flow hole 110, and the pot body assembly also includes a second heat dissipation fan 600 arranged corresponding to the flow hole 110. The second heat dissipation fan 600 is operated to form a flow airflow in the heat preservation cover 100 to cool the inner pot 200 and / or the heating plate 300.

[0056] In this way, by providing a flow hole 110 on the side of the heat preservation cover 100 and correspondingly setting a second heat dissipation fan 600, a larger range of cooling and heat dissipation can be achieved, thereby taking away the heat of the inner pot and / or the heating plate more quickly, allowing the water film to form faster, and further improving the non-stick performance of the inner pot.

[0057] In a specific embodiment, the heat dissipation cavity 900 has a flow port communicating with the flow hole 110, and one of the heat dissipation fan 500 and the second heat dissipation fan 600 is an air suction fan, and the other is an air exhaust fan. For example, the heat dissipation fan 500 is an air suction fan, and the second heat dissipation fan 600 is an air exhaust fan. The heat dissipation fan 500 draws cold air from the outside to cool the heating plate 300 in the heat dissipation cavity, and the second heat dissipation fan 600 draws the airflow in the heat dissipation cavity to the outside of the heat dissipation cavity through the flow port, cools the inner liner 200 and / or the heating plate 300 outside the heat dissipation cavity, and then exhausts it to the outside through the second heat dissipation fan 600.

[0058] Of course, the cooling fan 500 can also be independent of the second cooling fan 600, that is, the cooling fan 500 alone cools the heating plate 300 located in the cooling cavity, and the second cooling fan 600 alone cools the inner tank 200 and / or the heating plate 300 outside the cooling cavity, which is not limited here.

[0059] In some embodiments of the present invention, reference Figure 2 , Figure 3 and Figure 4 The heating plate 300 has a pin 340, the heat preservation cover 100 is provided with a pin hole 120 for the pin 340 to pass through, and the heat dissipation cavity 900 is communicated with the pin hole 120, so that the airflow of the heat dissipation cavity 900 flows out from the pin hole 120 or the airflow flows into the heat dissipation cavity from the pin hole 120. Such a configuration can use the existing pin hole to achieve the inflow or outflow of airflow, without opening another hole on the heat preservation cover, thereby reducing the production cost.

[0060] Optional, reference Figure 2 and Figure 4 The heat dissipation fan 500 is an air suction fan. The main body 401 is provided with a docking hole 402 corresponding to the air outlet end of the heat dissipation fan 500, and a through hole 404 corresponding to the pin hole 120. The docking hole 402 and the through hole 404 are located on two opposite sides of the main body 401, so that the cold air absorbed from the outside by the heat dissipation fan 500 flows along the heat dissipation cavity for a circle and then flows out from the pin hole 120, thereby making the cold air fully contact with the high temperature area of ​​the heating plate, which is conducive to the rapid reduction of the temperature of the heating plate.

[0061] In some embodiments of the present invention, reference Figure 2 , Figure 3 and Figure 5 The pot assembly further includes an air guide 700, one end of which is connected to the heat dissipation cavity 900, and the other end of which is provided with the heat dissipation fan 500. The provision of the air guide 700 can reduce the probability of the airflow colliding with the structure inside the pot assembly and generating turbulence during the flow process, so that the airflow can flow into or out of the heat dissipation cavity in a concentrated and orderly manner, thereby ensuring the cooling efficiency.

[0062] Optional, reference Figure 5 The cooling fan 500 is a suction fan, and the air guide 700 is provided with a reducing section 720, so that the cross-sectional area of ​​the connecting end of the air guide 700 and the cooling cavity 900 is smaller than the cross-sectional area of ​​the other end, thereby increasing the wind speed of the cooling fan 500 blowing the cold air into the cooling cavity, and further improving the cooling efficiency.

[0063] The present invention does not limit the position of the cooling fan 500. In a specific embodiment, Figure 1 and Figure 2The air guide 700 and the heat dissipation fan 500 are located below the heat preservation cover 100 and between the heat preservation cover 100 and the base 800 of the pot body assembly. The base 800 is provided with an air outlet 810 corresponding to the heat dissipation fan 500, so that the heat dissipation fan 500 can extract cold air from the air outlet 810 or discharge the air flow to the outside through the air outlet 810. Of course, the heat dissipation fan 500 can also be located at the side of the pot body assembly, and convey cold air to the heat dissipation cavity or discharge the gas in the heat dissipation cavity from one side of the heat dissipation cavity. Those skilled in the art can make a choice according to actual conditions.

[0064] For further reference, Figure 1 A flow channel is provided on the base 800, and an air outlet 810 is formed in the flow channel. One end portion of the air guide member 700 of the heat dissipation fan 500 extends into the flow channel (for example, the extending distance is not less than 2 mm), and the portion extending into the flow channel is in contact with the inner wall of the flow channel, or the gap between the portion and the inner wall of the flow channel is less than 0.5 mm, so as to avoid a large amount of airflow entering and exiting the gap between the heat dissipation fan and the flow channel and affecting the heat dissipation efficiency.

[0065] Optional, reference Figure 4 and Figure 5 The end of the air guide 700 that is connected to the heat dissipation cavity 900 is provided with a snap-on convex rib 710, the heat preservation cover 100 is provided with a through hole for the air guide 700 to pass through, and the main body 401 is provided with a docking hole 402 and a plug hole 403 for the snap-on convex rib 710 to pass through corresponding to the air guide 700. During assembly, the air guide 700 is aligned with the docking hole 402 and passes through the through hole on the heat preservation cover 100, and the snap-on convex rib 710 is correspondingly inserted into the plug hole 403, and then the snap-on convex rib 710 is bent to make it rest on the main body 401. In this way, while the air guide 700 is assembled, the wind shield panel 400 can also be positioned without setting additional positioning members, the structure is simple, and the cost is low.
