Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a high-temperature steam cooking appliance. Background Art

[0002] The liquid in a saturated state is called a saturated liquid, and its corresponding steam is saturated steam, but it is only wet saturated steam at first, and it becomes dry saturated steam only after the water in the saturated water evaporates completely. The temperature of steam does not increase during the process from unsaturated to wet saturated to dry saturated (the temperature remains unchanged from wet saturated to dry saturated). If dry saturated steam continues to be heated under constant pressure, the temperature will rise and become superheated steam. Superheated steam has the characteristics of strong penetration and high baking heating efficiency when heating food, so it is increasingly used in the field of home appliances, especially in steam cooking utensils. Compared with the traditional method of using saturated steam to heat food, the cooking efficiency of superheated steam heating is higher and the cooking time is shorter.

[0003] Cooking utensils that use superheated steam for heating are equipped with a water barrier and a heating hood in the water tank. The water barrier is arranged outside the heating hood, thereby dividing the internal space of the water tank into two cavities. The liquid in the water tank is first heated in the cavity outside the water barrier to produce wet saturated steam, and then enters the water barrier through the air inlet on the water barrier, and then enters the internal space of the heating hood. The wet saturated steam is heated again inside the heating hood to form superheated steam, and then enters the cooking cavity through the exhaust port on the water barrier to heat the food.

[0004] Superheated steam components often require multiple parts to cooperate with each other to form an evaporation chamber and a superheating chamber. Not only is the structure complex and the cost high, but the user needs to install each part separately before use, which makes the preparation work before cooking extremely cumbersome and the learning cost for new users is also high. The position of each part must be accurate during the assembly process, otherwise it will affect the generation of superheated steam and affect the cooking efficiency.

[0005] In addition, after cooking, users need to disassemble the superheated steam components and clean them separately, which increases the user's cleaning burden and provides a poor user experience. Utility Model Content

[0006] The utility model provides a high-temperature steam cooking utensil to solve the problems that the existing superheated steam assembly has many parts and a complex structure, and is cumbersome for users to assemble and clean, which affects the use experience.

[0007] The technical solution adopted by the utility model is:

[0008] A high-temperature steam cooking appliance comprises a cooking cavity and a water storage cavity located below the cooking cavity, wherein a first heating element for heating water to generate steam and a second heating element located above the first heating element and used for heating steam are arranged in the water storage cavity, a juice receiving tray is arranged between the water storage cavity and the cooking cavity, the juice receiving tray is provided with an air guide, the air guide cover is arranged on the outside of the second heating element, the air guide and the second heating element cooperate to form a superheated steam channel, and the air guide is provided with a steam outlet connected to the cooking cavity.

[0009] The high temperature steam cooking appliance of the utility model also has the following additional technical features:

[0010] The air guide member has a partition protruding toward the water storage cavity, the partition includes a main body and an air guide cover protruding toward the cooking cavity, the second heating member is located in the space surrounded by the air guide cover, and the main body surrounds the outer circumference of the second heating member.

[0011] The air guide member cooperates with the side wall of the second heating member to form the superheated steam channel. A convergence space is provided between the air guide member and the top wall of the second heating member, and the steam outlet is communicated with the convergence space.

[0012] The air guide member forms an overheating chamber in the water storage chamber, and a partial area of ​​the air guide member extends obliquely from bottom to top, so that the width of the overheating chamber gradually decreases from bottom to top.

[0013] A steaming rack is arranged in the cooking cavity, and an air flow opening is opened in the steaming rack. The size of the steam outlet is smaller than the size of the air flow opening.

[0014] The bottom wall of the water storage cavity is provided with an upwardly protruding mounting boss, the first heating element is provided on the bottom wall of the water storage cavity, and the second heating element is provided on the mounting boss.

[0015] A maximum water level mark is arranged in the water storage cavity, and the height of the position where the maximum water level mark is located is not higher than the top surface of the mounting boss.

[0016] The surface of the second heating element is coated with a food-grade coating; or the surface of the second heating element is provided with a food-grade oxidation layer.

[0017] The bottom wall of the juice receiving tray is provided with a matching boss, the top surface of the matching boss is higher than the bottom wall of the juice receiving tray, and the air guide is provided on the matching boss.

[0018] The matching boss is provided with a mounting opening, the air guide and the juice receiving tray are separately formed structures, and the air guide is fixed to the mounting opening.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0020] 1. In the utility model, there is no need to arrange a large number of components with complex structures in the water storage cavity to enclose a heating cavity or a steam channel for generating superheated steam. It is only necessary to improve the structure of the juice receiving tray and arrange the air guide on the juice receiving tray. Then, when the user places the juice receiving tray above the water storage cavity, the air guide cooperates with the second heating element in the water storage cavity to form the superheated steam channel. The saturated steam generated by the water in the water storage cavity flows into the superheated steam channel, fully contacts with the second heating element and is converted into superheated steam, and is finally discharged into the cooking cavity through the steam outlet.

[0021] The utility model forms a superheated steam channel by cooperating the air guide member arranged on the juice receiving tray with the second heating member, which not only simplifies the structure of the superheated steam assembly, but also reduces the number of components in the water storage chamber, thereby saving costs. Before cooking, the user only needs to place the juice receiving tray on the water storage chamber to complete the assembly, which greatly simplifies the assembly steps, reduces the difficulty of operation, and is more user-friendly for new users. In addition, after cooking, as the juice receiving tray is removed from above the water storage chamber, the first heating member and the second heating member are exposed in the water storage chamber, so that the user can directly clean the two, thereby improving the convenience of cleaning.

[0022] 2. As a preferred embodiment of the present invention, the air guide has a partition protruding toward the water storage cavity, the partition includes a body and an air guide cover protruding toward the cooking cavity, the second heating element is located in the space surrounded by the air guide cover, and the body surrounds the outer periphery of the second heating element. The partition protrudes toward the water storage cavity and surrounds the second heating element, the partition divides the space in the water storage cavity into an evaporation cavity located outside the partition plate and an overheating cavity located inside the partition, and a local area of ​​the partition protrudes upward to form an air guide cover to cover the second heating element, thereby forming an overheated steam channel in the overheating cavity. After the water in the evaporation cavity is heated to generate steam, it passes from the bottom of the partition into the overheating cavity inside, and continues to be heated in the overheating cavity to be converted into overheated steam. At the same time, the partition first protrudes downward and then partially protrudes upward, which can reduce the overall height of the air guide, thereby saving space in the height direction and helping to achieve miniaturization of the whole machine.

[0023] 3. As a preferred embodiment of the present invention, the air guide cooperates with the side wall of the second heating element to form the superheated steam channel, and there is a gathering space between the air guide and the top wall of the second heating element, and the steam outlet is connected to the gathering space. During the upward flow of the saturated steam entering the superheated steam channel, it is heated by the second heating element and converted into superheated steam. However, the air pressure of the superheated steam is relatively low and the flow rate is relatively slow. The superheated steam is briefly gathered in the gathering space above the second heating element. As the amount of superheated steam in the gathering space increases, the air pressure increases, and the superheated steam is ejected from the steam outlet into the cooking cavity at a relatively high pressure, and quickly diffuses in the cooking cavity, so that the superheated steam distribution between the upper and lower layers in the cooking cavity and in each area is more uniform, thereby improving the uniformity of heating of food between different layers and improving the cooking taste.

[0024] 4. As a preferred embodiment of the present invention, the bottom wall of the water storage chamber is provided with an upwardly protruding mounting boss, the first heating element is provided on the bottom wall of the water storage chamber, and the second heating element is provided on the mounting boss. In this embodiment, the second heating element is raised by the mounting boss so that it is higher than the bottom wall of the water storage chamber, thereby naturally dividing the water storage chamber into two upper and lower cavities. Water is concentrated at the bottom wall of the water storage chamber under the action of gravity, and is heated by the first heating element to produce saturated steam. The steam will reach the second heating element above during the floating process, and is further heated by the second heating element and converted into superheated steam. In this way, the buoyancy characteristics of steam are utilized to further heat it during its upward floating, so that a better superheated steam generation effect can be obtained without providing a partition in the water storage chamber, which simplifies the structure and saves costs.

[0025] 5. As a preferred embodiment of the present invention, the surface of the second heating element is coated with a food-grade coating; or, the surface of the second heating element is provided with a food-grade oxide layer. The provision of the coating or oxide layer improves the safety of the high-temperature steam cooking appliance, avoids corrosion damage to the second heating element caused by steam, and increases the service life of the second heating element. At the same time, it also makes the second heating element easier to clean. The user only needs to rinse it with water or simply wipe its surface when it needs to be cleaned, which improves the user's experience. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0046] like Figures 1 to 6 As shown, a high-temperature steam cooking appliance comprises a cooking cavity 1 and a water storage cavity 2 located below the cooking cavity 1, wherein a first heating element 3 for heating water to generate steam and a second heating element 4 located above the first heating element 3 and used for heating steam are arranged in the water storage cavity 2, a juice receiving tray 5 is arranged between the water storage cavity 2 and the cooking cavity 1, the juice receiving tray 5 is provided with an air guide 6, the air guide 6 is covered on the outside of the second heating element 4, the air guide 6 cooperates with the second heating element 4 to form an overheated steam channel 23, and the air guide 6 is provided with a steam outlet 62 connected to the cooking cavity 1.

[0047] It should be noted that in the high-temperature steam cooking appliance of the present invention, "high temperature" is relative to traditional steam cooking appliances (such as steamers, etc.). The high-temperature steam cooking appliance in the present invention uses superheated steam for heating, and the heating efficiency is higher than the traditional heating using saturated steam, so it is named high-temperature steam cooking appliance.

[0048] In the prior art, at least two covers are arranged in the water storage cavity, which are stacked inside and outside to form an overheating cavity or a steam channel. Before cooking, the user needs to install the two covers in the water storage cavity respectively.

[0049] In the present invention, however, all the covers installed in the water storage chamber 2 are completely omitted, that is, there is no need to set a large number of complex components in the water storage chamber 2 to enclose a heating chamber or a steam channel for generating superheated steam. It is only necessary to improve the structure of the juice receiving tray 5 and set the air guide 6 on the juice receiving tray 5. Then, when the user places the juice receiving tray 5 above the water storage chamber 2, the air guide 6 cooperates with the second heating element 4 in the water storage chamber 2 to form the superheated steam channel 23. The saturated steam generated by the heated water in the water storage chamber 2 flows into the superheated steam channel 23, fully contacts with the second heating element 4 and is converted into superheated steam, and is finally discharged into the cooking chamber 1 through the steam outlet 62.

[0050] The utility model forms a superheated steam channel 23 by cooperating the air guide 6 arranged on the juice receiving tray 5 with the second heating element 4, which not only simplifies the structure of the superheated steam assembly, but also reduces the number of components in the water storage chamber 2, thereby saving costs. Before cooking, the user only needs to place the juice receiving tray 5 on the water storage chamber 2 to complete the assembly, which greatly simplifies the assembly steps, reduces the difficulty of operation, and is more user-friendly for new users. While saving costs, the high-temperature steam will not fail due to missing accessories. In addition, after cooking, as the juice receiving tray 5 is removed from above the water storage chamber 2, the first heating element 3 and the second heating element 4 are both exposed in the water storage chamber 2, so that the user can directly clean the two, thereby improving the convenience of cleaning.

[0051] The assembly relationship and assembly sequence of the cooking utensil of the present invention are as follows: first, the external water tank with the water storage chamber 2 is mounted and fixed on the body shell, and then the first heating element 3 is mounted and fixed on the shell; then the second heating element 4 is mounted and fixed above the first heating element 3; the air guide member 6 is fixed on the juice receiving tray 5 to form an assembly, and then the juice receiving tray assembly is placed as a whole on the shell above the water storage chamber 2.

[0052] As a preferred embodiment of the present invention, Figure 2 , Figure 4 , Figure 5As shown, the air guide member 6 has a partition 61 protruding toward the water storage chamber 2, and the partition 61 includes a main body 611 and an air guide cover 612 protruding toward the cooking chamber 1. The second heating member 4 is located in the space enclosed by the air guide cover 612, and the main body 611 surrounds the outer periphery of the second heating member 4.

[0053] like Figure 1 As shown, the partition 61 protrudes toward the water storage chamber 2 and surrounds the second heating element 4. The partition 61 divides the space in the water storage chamber 2 into an evaporation chamber 21 located on the outside of the partition plate and an overheating chamber 22 located on the inside of the partition 61. A local area of ​​the partition 61 bulges upward to form an air guide cover 612 to cover the second heating element 4, thereby forming an overheated steam channel 23 in the overheating chamber 22.

[0054] After the water in the evaporation chamber 21 is heated to generate steam, it passes under the partition 61 and enters the inner superheating chamber 22, where it continues to be heated and converted into superheated steam. At the same time, the partition 61 first bulges downward and then partially bulges upward, which can avoid the second heating element 4 while also reducing the overall height of the air guide 6, thereby saving space in the height direction and helping to achieve miniaturization of the entire machine.

[0055] Preferably, the air guide 6 is made of a heat-conducting material (such as metal), or a heat-conducting layer is provided on the side of the air guide 6 facing the second heating element 4. The heat of the second heating element 4 can be radiated to the air guide 6, so that the air guide 6 quickly rises in temperature, which plays an auxiliary heating role for the steam. The steam is heated by the second heating element 4 and the air guide 6, which accelerates the generation of superheated steam and improves cooking efficiency.

[0056] In a preferred embodiment, Figure 2 , Figure 4 As shown, the air guide 6 cooperates with the side wall of the second heating element 4 to form the superheated steam channel 23 , a convergence space 24 is defined between the air guide 6 and the top wall of the second heating element 4 , and the steam outlet 62 is connected to the convergence space 24 .

[0057] It can be understood that saturated steam enters the superheated steam channel 23 from the lower part of the second heating element 4, and the steam outlet 62 is located above the second heating element 4. In the process of flowing upward, the saturated steam entering the superheated steam channel 23 is heated by the second heating element 4 and converted into superheated steam. However, the gas pressure of the superheated steam is relatively low and the flow rate is relatively slow at this time. The superheated steam is briefly gathered in the convergence space 24 above the second heating element 4. As the superheated steam in the convergence space 24 increases, the gas pressure increases, and the superheated steam is ejected from the steam outlet 62 into the cooking cavity 1 at a relatively high pressure, and quickly diffuses in the cooking cavity 1, so that the superheated steam distribution between the upper and lower layers and in each area of ​​the cooking cavity 1 is more uniform, thereby improving the uniformity of heating of food between different layers and improving the cooking taste.

[0058] Furthermore, if Figure 2 , Figure 4 As shown, the air guide 6 forms an overheating chamber 22 in the water storage chamber 2, and a partial area of ​​the air guide 6 extends obliquely from bottom to top, so that the width of the overheating chamber 22 gradually decreases from bottom to top.

[0059] The width of the superheating chamber 22 gradually decreases along the flow direction of the steam, and the steam pressure gradually increases during the flow of the steam, and finally the steam is ejected from the steam outlet 62 with a larger pressure and kinetic energy. The width of the lower part of the superheating chamber 22 is larger, and the flow speed of the steam is slower, so the contact time between the steam and the second heating element 4 can be extended, so that the steam is fully heated and converted into superheated steam.

[0060] Preferably, a steaming rack is provided in the cooking cavity 1, the steaming rack is provided with an air flow opening, and the size of the steam outlet 62 is smaller than the size of the air flow opening.

[0061] In this embodiment, by reducing the size of the steam outlet 62, the amount of superheated steam discharged from the steam outlet 62 per unit time is reduced, thereby generating a micro-pressure environment in the superheated steam channel 23 surrounded by the air guide 6 and the second heating element 4, and further increasing the speed of the superheated steam when it is ejected. In addition, by controlling the opening size of the steam outlet 62, the contact time of the saturated steam with the second heating element 4 can be adjusted to control the steam outlet temperature.

[0062] As a preferred embodiment of the present invention, Figure 2 , Figure 4 As shown, the bottom wall of the water storage chamber 2 is provided with an upwardly protruding mounting boss 25 , the first heating element 3 is provided on the bottom wall of the water storage chamber 2 , and the second heating element 4 is provided on the mounting boss 25 .

[0063] like Figure 2, Figure 4 As shown, in this embodiment, the second heating element 4 is raised by the mounting boss 25 to be higher than the bottom wall of the water storage chamber 2, thereby naturally dividing the water storage chamber 2 into two upper and lower chambers. Water is concentrated at the bottom wall of the water storage chamber 2 under the action of gravity, and is heated by the first heating element 3 to produce saturated steam. The steam will reach the second heating element 4 above during the floating process, and is further heated by the second heating element 4 to be converted into superheated steam. In this way, the buoyancy characteristics of steam are utilized to further heat it during its upward floating, so that a better superheated steam generation effect can be obtained without setting a partition in the water storage chamber 2, simplifying the structure while also saving costs.

[0064] Furthermore, a maximum water level mark is provided in the water storage chamber 2 , and the height of the maximum water level mark is no higher than the top surface of the mounting boss 25 .

[0065] By setting the maximum water level mark, the amount of water added by the user to the water storage chamber 2 is limited, so that the liquid level is kept below the mounting boss 25, thereby limiting the purpose of the first heating element 3 and the second heating element 4. The first heating element 3 is only used to heat the water in the water storage chamber 2 to generate saturated steam, while the second heating element 4 is located above the liquid level, so it is only used to heat the rising saturated steam to generate superheated steam, and does not participate in the heating of water. This not only improves the efficiency of superheated steam generation, but also because the second heating element 4 has a higher temperature, it can avoid directly heating the water, causing the water to boil violently and generate noise.

[0066] Preferably, the surface of the second heating element 4 is coated with a food-grade coating; or, the surface of the second heating element 4 is provided with a food-grade oxidation layer.

[0067] Specifically, the second heating element 4 includes a heat transfer element and a heating element arranged inside the heat transfer element. The heat transfer element is block-shaped and covers the heating element. The surface of the heat transfer element is coated with a food-grade coating or the surface of the heat transfer element is provided with a food-grade oxidation layer. This not only improves the safety of high-temperature steam cooking utensils, but also avoids corrosion damage to the second heating element 4 caused by steam, and increases the service life of the second heating element 4. At the same time, it also makes the second heating element 4 more convenient to clean. The user only needs to rinse it with water or simply wipe the surface of the heat transfer element when it needs to be cleaned, which improves the user's experience.

[0068] Optionally, a coating or an oxidation layer is also provided on the surface of the air guide member 6 facing the second heating member 4 .

[0069] In addition, the first heating element 3 is a heating plate disposed at the bottom of the water storage chamber 2, and is used to heat the water in the water storage chamber 2. The first heating element 3 can be located in the water storage chamber 2, or it can be located at a position other than the heating element 3. Figure 2 , Figure 4 As shown, it constitutes the bottom wall of the water storage chamber 2.

[0070] As a preferred embodiment of the present invention, Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the bottom wall of the juice receiving tray 5 is provided with a matching boss 51 , the top surface of the matching boss 51 is higher than the bottom wall of the juice receiving tray 5 , and the air guide 6 is provided on the matching boss 51 .

[0071] The air guide 6 is arranged on the bottom wall of the juice receiving tray 5 by providing a matching boss 51, and the matching boss 51 is higher than the bottom wall of the juice receiving tray 5, so that liquids such as food soup and condensed water dripping from above will be concentrated on the bottom wall of the juice receiving tray 5, and the matching boss 51 forms a barrier to the liquid, so that it cannot flow to the air guide 6, thereby ensuring the cleanliness of the air guide 6 and preventing the liquid from dripping from the steam outlet 62 on the air guide 6 into the water storage chamber 2, causing the second heating element 4 or the water storage chamber 2 to be contaminated.

[0072] Furthermore, if Figure 2 , Figure 4 As shown, the air guide 6 has a partition 61 protruding toward the water storage cavity 2, the partition 61 includes a body 611 and an air guide cover 612 protruding toward the cooking cavity 1, and the steam outlet 62 is arranged at the top of the air guide cover 612, so as to further increase the difficulty of the liquid on the juice receiving tray 5 to drip from the steam outlet 62.

[0073] It should be noted that the utility model does not limit the assembly method of the air guide member 6 and the juice receiving tray 5. In an embodiment, the air guide member 6 and the juice receiving tray 5 are an integrally formed structure to simplify assembly.

[0074] In another embodiment, if Figure 6 As shown, the matching boss 51 is provided with a mounting opening 52 , the air guide 6 and the juice receiving tray 5 are separately formed structures, and the air guide 6 is fixed to the mounting opening 52 .

[0075] The separately formed air guide 6 and the juice receiving tray 5 can be processed separately using different materials. For example, the juice receiving tray 5 can be made of plastic to save costs, while the air guide 6 can be made of metal to have better thermal conductivity and better high temperature resistance.

[0076] Specifically, Figure 3 As shown, the mating boss 51 and the air guide 6 are respectively provided with fixing holes, through which the fasteners 7 (such as screws, etc.) pass to fasten the two together. Of course, the two can also be fixed in other ways, such as clamping, welding, etc., which are not limited here.

[0077] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0078] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0079] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
