Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to a cooking utensil capable of quickly generating steam. Background Art

[0002] The usual heating method of cooking appliances such as electric steamers is to heat all the water in the water tank. The water temperature rises slowly and the preheating time is very long, which affects the efficiency of the electric steamer.

[0004] The disadvantage of the prior art is that the insulation zone formed between the partition cover and the insulation ring is an air cavity with an upper opening. When the heating zone is heated, convection between the air inside the insulation zone and the outside air will cause poor heat accumulation in the heating zone and affect the steam generation rate. Summary of the invention

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] In the above-mentioned cooking appliance, the heat-insulating cavity is arranged around the outside of the first heating device.

[0009] In the above-mentioned cooking utensil, the heat-insulating chamber is a vacuum chamber.

[0010] In the above-mentioned cooking utensil, the insulation cavity is filled with insulation medium; and / or the energy focusing ring is made of insulation material; and / or the cavity wall of the insulation cavity is coated with insulation coating; and / or the cavity wall of the insulation cavity is inlaid with insulation layer.

[0011] In the above-mentioned cooking utensil, the bottom of the energy gathering ring is arranged to fit the bottom of the water tank, and the water inlet recess is located at the bottom of the water tank.

[0012] In the above-mentioned cooking utensil, a positioning groove for positioning the energy focusing ring is provided at the bottom of the water tank.

[0013] In the above-mentioned cooking utensil, the water inlet recess is located inside the positioning groove, and the water inlet recess is arranged adjacent to the groove wall of the positioning groove.

[0014] In the above-mentioned cooking utensil, the upper and lower ends of the energy focusing ring are arranged in mirror symmetry.

[0015] In the above-mentioned cooking utensil, a plurality of water inlet recesses are provided, and the plurality of water inlet recesses are arranged in an array around the axis of the energy focusing ring.

[0016] In the above-mentioned cooking utensil, the first heating device includes an inner heating tube and a middle heating tube located at the bottom of the water tank, the middle heating tube is an annular structure, and the inner heating tube is located on the inner side of the middle heating tube.

[0017] Beneficial effects of the utility model:

[0018] The utility model discloses a cooking utensil, in which the water in the water tank is heated by a first heating device in the heating base, and steam is generated to cook the food in the pot on the upper side of the heating base. The utility model provides an energy-gathering ring in the water tank capable of being heated, and the heat insulation of the inside and outside of the energy-gathering ring is achieved by the heat insulation cavity of the energy-gathering ring. When it is necessary to quickly generate steam for cooking, the water inside the energy-gathering ring is quickly heated by the first heating device to ensure cooking efficiency. Since the heat insulation cavity is sealed, the heat insulation cavity will not form air convection heat exchange with the outside world, thereby improving the heat insulation effect of the energy-gathering ring, thereby improving the steam generation efficiency of the cooking utensil and reducing the preheating time. The water inside the energy-gathering ring can be replenished by the provision of the water inlet recess, and the water outside the energy-gathering ring in the water tank can enter the energy-gathering ring from the water inlet recess, thereby avoiding the situation where the inside of the energy-gathering ring is dry-burned.

[0019] Furthermore, the heat-insulating cavity is arranged around the outside of the first heating device. The heat-insulating cavity arranged around the outside of the first heating device is used to achieve continuous heat-insulating effect on the outside of the first heating device, ensuring the heat-insulating effect of the heat-insulating cavity on the inside and outside of the energy-gathering ring.

[0020] Furthermore, the heat insulation cavity is a vacuum cavity. The provision of the vacuum cavity can reduce heat conduction media such as air, reduce heat convection inside the heat insulation cavity, and thus improve the heat insulation effect of the heat insulation cavity.

[0021] Furthermore, the heat-insulating cavity is filled with a heat-insulating medium; and / or the energy-gathering ring is made of a heat-insulating material; and / or the cavity wall of the heat-insulating cavity is coated with a heat-insulating coating; and / or the cavity wall of the heat-insulating cavity is inlaid with a heat-insulating layer. The above schemes are all methods for enhancing the heat-insulating capacity of the heat-insulating cavity, which can be used in combination or alone. The configuration of the above schemes can further improve the heat-insulating effect of the heat-insulating cavity.

[0022] Furthermore, the bottom of the energy focusing ring is arranged in contact with the bottom of the water tank, and the water inlet recess is located at the bottom of the water tank. The bottom of the energy focusing ring is arranged in contact with the bottom of the water tank to ensure the spatial separation effect of the energy focusing ring on the water tank and reduce the water convection on both sides of the energy focusing ring. The water inlet recess is located at the bottom of the water tank, which is a further recess on the bottom surface of the water tank. The water inlet recess corresponds to the bottom position of the energy focusing ring. The first heating position is located at the inner side of the bottom of the energy focusing ring. Since the height of the water inlet recess is lower than the bottom of the energy focusing ring, the water inlet recess is subjected to a small force from hot water. Compared with the method of setting the water inlet recess on the energy focusing ring, the impact force of boiling water on the bottom of the energy focusing ring during heating can be reduced.

[0023] Furthermore, a positioning groove for positioning the energy-gathering ring is provided at the bottom of the water tank, so as to facilitate the installation of the energy-gathering ring.

[0024] Furthermore, the water inlet recess is located inside the positioning groove, and the water inlet recess is arranged adjacent to the groove wall of the positioning groove. Due to the arrangement of the positioning groove, the bottom of the energy focusing ring is lower than the bottom of the water tank outside the energy focusing ring, so that the water in the water tank outside the energy focusing ring can reliably flow into the inside of the energy focusing ring, and then be evaporated outside the energy focusing ring, thereby extending the life of the corresponding water tank part inside the energy focusing ring.

[0025] Furthermore, the two axial ends of the energy-gathering ring are arranged in mirror symmetry, and the axial installation position of the energy-gathering ring can be swapped, which is convenient for customers to take and put.

[0026] Furthermore, there are a plurality of water inlet recesses, which are arranged in an array around the axis of the energy focusing ring, so as to achieve water inlet at multiple positions and improve the uniformity of water inlet inside the energy focusing ring.

[0027] Furthermore, the first heating device includes an inner heating tube and a middle heating tube located at the bottom of the water tank, the middle heating tube is an annular structure, and the inner heating tube is located inside the middle heating tube. The inner heating tube and the middle heating tube are combined to form multi-area common heating to ensure the heating efficiency of the water body inside the energy focusing ring. The middle heating tube is arranged in an annular shape to provide a relatively uniform heating effect inside the energy focusing ring, avoiding uneven heating that causes large differences in the boiling state of the water flow inside the energy focusing ring in the lateral direction, thereby causing a large lateral force on the energy focusing ring and affecting the reliability of the energy focusing ring.

[0028] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0037] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore, cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] Reference Figures 1 to 5 A cooking utensil proposed in one of the embodiments of the utility model comprises a heating base 1, a pot body 7 and a pot cover 8. The pot body 7 is placed on the heating base 1, and the pot cover 8 is covered on the pot body 7. A water tank 2 is provided in the heating base 1, and an energy focusing ring 3 is provided in the water tank 2. A first heating device 4 is provided below the water tank 2 at a position corresponding to the inner side of the energy focusing ring 3. The ring wall of the energy focusing ring 3 is provided with a closed insulation cavity 31. The water tank 2 and the energy focusing ring 3 are spaced apart, and a water inlet recess 21 for connecting the inner and outer sides of the energy focusing ring 3 is provided at the bottom of the water tank 2 and / or the bottom of the energy focusing ring 3.

[0039] In this embodiment, the heating base 1 can heat the internal water tank 2, so that the water in the water tank 2 is converted into steam, and the food in the pot body 7 is cooked by the heat of the steam. In order to increase the speed of steam generation and shorten the preheating time of the cooking utensil, this embodiment is provided with an energy-gathering ring 3 in the water tank 2, and the first heating device 4 corresponds to the inner side of the energy-gathering ring 3, so that the heating effect of the first heating device 4 is mainly concentrated on the inner side of the energy-gathering ring 3, and the amount of water inside the energy-gathering ring 3 is smaller than the overall amount of water in the water tank 2, so that steam can be generated more quickly and the preheating time of the cooking utensil can be reduced. In this embodiment, a heat-insulating chamber 31 is provided in the energy-gathering ring 3, and heat insulation of the inside and outside of the energy-gathering ring 3 is achieved through the heat-insulating chamber 31. The heat-insulating chamber 31 is a closed chamber, which reduces the air in the heat-insulating chamber 31 as a heat-conducting medium to exchange heat with the outside, thereby improving the energy-gathering effect of the energy-gathering ring 3. The setting of the water inlet recess 21 allows the water inside and outside the energy-gathering ring 3 to circulate. During the evaporation of steam inside the energy-gathering ring 3, the water outside the energy-gathering ring 3 can be replenished inward, thereby avoiding dry burning inside the energy-gathering ring 3.

[0040] The water inlet recess 21 serves as a communicating portion between the inner and outer sides of the energy focusing ring 3 and adopts a groove or through-hole structure.

[0041] The energy focusing ring 3 is a double-layer structure with a closed heat-insulating cavity 31 in the middle, so as to achieve reliable energy focusing of the first heating device 4 .

[0042] like Figure 1 This is an example solution when the cooking utensil of the present application is an electric steamer, wherein the pot body 7 is two detachable steamers stacked together, and a juice receiving tray 6 is provided at the bottom of the pot body 7. The central part of the juice receiving tray 6 is a perforated plate structure 61 corresponding to the energy focusing ring 3. The height of the perforated plate structure 61 is higher than the bottom surface of the juice receiving tray 6. The steam in the energy focusing ring 3 overflows from the perforated plate structure 61 into the steamer to complete the cooking of the ingredients. The pot cover 8 covers the upper end of the upper steamer. Afterwards, because the bottom surface of the juice receiving tray 6 is lower than the perforated plate structure 61, the water condenses and accumulates on the juice receiving tray 6.

[0043] Those skilled in the art will appreciate that, in addition to the electric steamer, the cooking utensil may be other types of utensil that utilizes steam to cook food.

[0044] As one of the embodiments of the present invention, a cooking utensil is provided. Figure 1 and Figure 2 As shown, the heat-insulating cavity 31 is arranged around the outside of the first heating device 4. That is, the heat-insulating cavity 31 is arranged inside the energy focusing ring 3 along the circumference of the energy focusing ring 3. The heat-insulating cavity 31 can continuously block the inside of the heating area inside the energy focusing ring 3 to ensure the heat insulation effect. Furthermore, in this embodiment, the heat-insulating cavity 31 is a vacuum cavity. The "vacuum cavity" here means that the air pressure inside the heat-insulating cavity 31 is less than the standard atmospheric pressure, and the heat-conducting medium is less, and it is not limited to a completely vacuum situation.

[0045] Furthermore, in order to improve the thermal insulation performance of the thermal insulation cavity 31, optionally, the thermal insulation cavity 31 is filled with a thermal insulation medium; or, the energy focusing ring 3 is made of a thermal insulation material; or, the cavity wall of the thermal insulation cavity 31 is coated with a thermal insulation coating; or, the cavity wall of the thermal insulation cavity 31 is inlaid with an insulation layer.

[0046] It is obvious that those skilled in the art can understand that the above schemes for improving the thermal insulation performance of the thermal insulation cavity 31 can be used alone or in combination, or in combination of two or three. Obviously, it can also be used in combination with the thermal insulation cavity 31 being set as a vacuum cavity. In the above schemes, the thermal insulation medium can be a solid thermal insulation material such as sponge, or a heat-resistant gas. The thermal insulation material includes porous materials and heat-reflecting materials.

[0047] As a cooking utensil proposed in one of the embodiments of the utility model, the first heating device 4 includes an inner heating tube 41 and a middle heating tube 42 located at the bottom of the water tank 2. The middle heating tube 42 is annular, and the inner heating tube 41 is located on the inner side of the middle heating tube 42. The first heating device 4 corresponding to the inner side of the energy focusing ring 3 can reliably heat the water inside the energy focusing ring 3. The inner heating tube 41 and the middle heating tube 42 form a multi-point common heating structure, which cooperates with the annular middle heating tube 42 to improve the uniformity of heating. During rapid steaming, the inner heating tube 41900 watts and the middle heating tube 421200 watts heat the water inside the energy focusing ring 3 at the same time. The closed heat-insulating cavity 31 formed by the double-layer energy focusing ring 3 reduces heat loss, improves the utilization rate of heat, and makes the water inside the energy focusing ring 3 boil faster.

[0048] In one of the embodiments of the utility model, on the basis of the above-mentioned scheme, a second heating device 5 is further provided at the bottom of the water tank 2, and the second heating device 5 corresponds to the outer side of the energy focusing ring 3. The first heating device 4 and the second heating device 5 are controlled by independent circuits. When the first heating device 4 heats the water inside the energy focusing ring 3, the second heating device 5 can be opened to heat the water outside the energy focusing ring 3.

[0049] As one of the embodiments of the present invention, a cooking utensil is provided. Figure 2 , Figure 4 and Figure 5 As shown, the bottom of the energy focusing ring 3 is arranged in contact with the bottom of the water tank 2, and the water inlet recess 21 is located at the bottom of the water tank 2. The water inlet recess 21 is a groove structure, and the width of the water inlet recess 21 in the radial direction of the energy focusing ring 3 is greater than the thickness of the energy focusing ring 3 in the radial direction, so that the water inlet recess 21 can reliably connect the inner and outer sides of the energy focusing ring 3. There are four water inlet recesses 21, and the four water inlet recesses 21 are arranged in an array around the axis of the energy focusing ring 3. A relatively uniform water replenishment of the inner side of the energy focusing ring 3 is achieved.

[0050] As a simple replacement of the above solution, the number of water inlet recesses 21 may be three, five, six, etc.

[0051] In this embodiment, the upper and lower ends of the energy focusing ring 3 are arranged in mirror symmetry. Figure 4 and Figure 5 As shown, the shape of the energy-gathering ring 3 is annular, which is convenient for the installation of the energy-gathering ring 3 in the water tank 2, and there is no need to find a special assembly position. A positioning groove 22 for positioning the energy-gathering ring 3 is provided at the bottom of the water tank 2. The lower end of the energy-gathering ring 3 extends into the positioning groove 22. The positioning groove 22 is a cylindrical groove, which can also be understood as a circular blind hole. When the energy-gathering ring 3 is placed in the positioning groove 22, the groove side wall of the positioning groove 22 is opposite to the side wall of the lower end of the energy-gathering ring 3, and the groove bottom wall of the positioning groove 22 is in contact with the end face of the lower end of the energy-gathering ring 3. The energy-gathering ring 3 is reliably positioned by the setting of the positioning groove 22, and the upper end of the energy-gathering ring 3 is limited by the orifice plate structure 61 of the juice receiving plate 6, so as to ensure the reliability of the setting of the energy-gathering ring 3 in the water tank 2.

[0052] Furthermore, in this embodiment, the water inlet recess 21 is located inside the positioning groove 22, and the water inlet recess 21 is arranged adjacent to the groove wall of the positioning groove 22. The water inlet recess 21 and the positioning groove 22 share a part of the groove side wall, and the water inlet recess 21 and the groove bottom wall of the positioning groove 22 are smoothly transitioned, and the edges of the water inlet recess 21 are all provided with rounded transition to avoid stress concentration. Since the energy focusing ring 3 is arranged inside the positioning groove 22, the height of the water tank 2 inside the energy focusing ring 3 is lower than the height of the water tank 2 outside the energy focusing ring 3. The water outside the energy focusing ring 3 can reliably flow to the inside of the energy focusing ring 3 under the action of gravity, which is convenient for water replenishment inside the energy focusing ring 3. Since the positioning and installation of the energy focusing ring 3 depends on the positioning groove 22, when the energy focusing ring 3 is installed in the positioning groove 22, the water inlet recess 21 arranged adjacent to the positioning groove 22 automatically corresponds to the lower end of the energy focusing ring 3, ensuring the water inlet effect of the water inlet recess 21 on the inside of the energy focusing ring 3.

[0053] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
