Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to a microwave cooking appliance. Background Technology
[0002] Existing cooking appliances primarily use heating plates and electromagnetic induction heating (IH). Both methods involve heating the inner metal pot first through heat conduction, then transferring the heat to the water inside the pot before cooking the food. This heat conduction method generally suffers from uneven heating of the food and low cooking efficiency. Therefore, the microwave rice cooker was invented, primarily utilizing the penetrating properties of microwaves to directly heat the water inside the pot and the food, offering advantages such as even and rapid heating.
[0003] In related technologies, a metal cavity is used to house the inner pot. When the inner pot is placed inside the metal cavity, the inner pot protrudes outside the cavity, which may cause collisions when the lid is closed. Furthermore, microwave rice cookers use inner pots made of glass or ceramic that are microwave-permeable, making them more susceptible to damage. Utility Model Content
[0004] The main purpose of this utility model is to provide a microwave cooking appliance that aims to solve the problem that existing microwave rice cookers may have collisions between the lid and the inner pot during the closing process, which can easily lead to damage to the inner pot.
[0005] To achieve the above objectives, this utility model proposes a microwave cooking appliance, which includes a pot body and a lid. The pot body includes a cavity and an inner pot, the inner pot being a microwave-permeable device. The cavity has an opening, and the inner pot is detachably disposed within the cavity. When the inner pot is placed within the cavity, the opening of the inner pot is higher than the opening of the cavity. The lid covers the opening of the cavity, and the upper side of the lid facing the cavity is recessed to form a receiving groove. The opening of the inner pot is located within the receiving groove. One of the outer wall of the inner pot or the inner wall of the cavity is provided with a protruding limiting part, and the other is provided with a mating part that abuts against the limiting part.
[0006] In one embodiment, the distance between the outer wall of the inner liner near the opening and the inner wall of the corresponding cavity is D1, and the distance between the outer wall of the inner liner away from the opening and the inner wall of the corresponding cavity is D2, satisfying the relationship: D1 < D2; the range of distance D1 is: 2mm ≤ D1 ≤ 5mm.
[0007] In one embodiment, the inner liner includes a liner body and the limiting portion, the limiting portion being disposed around the outer wall of the liner body.
[0008] In one embodiment, the outer wall of the limiting part is provided with a guide slope, and the circumference of the guide slope gradually increases from the opening end of the inner liner toward the bottom wall of the inner liner.
[0009] In one embodiment, the limiting part further includes a positioning sealing ring, which is disposed around the inner wall of the cavity, and the inner ring of the positioning sealing ring is used to abut against the mating part of the inner liner.
[0010] In one embodiment, the circumference of the inner wall of the cavity gradually decreases from the opening toward the end away from the opening.
[0011] In one embodiment, the inner ring of the positioning sealing ring has a guide slope, the circumference of which gradually decreases from the opening of the cavity toward the bottom wall of the cavity.
[0012] In one embodiment, the inner liner is made of glass or ceramic.
[0013] In one embodiment, the cover includes a microwave shielding cover, which is a metal part. The microwave shielding cover forms the receiving groove, and a shielding surface is provided at the opening of the cavity. The microwave shielding cover abuts against the shielding surface.
[0014] In one embodiment, the bottom wall of the receiving groove is provided with a sealing ring for sealing against the opening end of the inner liner.
[0015] Compared with the prior art, the microwave cooking appliance provided by this utility model has the following beneficial effects:
[0016] This utility model's technical solution uses a limiting part and a mating part between the outer wall of the inner liner and the inner wall of the cavity to confine the inner liner within the cavity, ensuring it is placed in the correct position. This guarantees the inner liner remains in the correct position during the closing process and throughout use, preventing movement. Therefore, even if the volume of the metal cavity is larger than the inner liner, the limiting of the inner liner after placement improves the accuracy of its alignment, enhances the precision of the latching between the lid and the inner liner, and prevents collisions between the lid and the protruding parts of the inner liner during closing. This reduces the risk of damage to the microwave-transparent inner liner and improves the user experience. Attached Figure Description

[0029] Existing cooking appliances primarily use heating plates and electromagnetic induction heating (IH). Both methods involve heating the inner metal pot first through heat conduction, then transferring the heat to the water inside the pot before cooking the food. This heat conduction method generally suffers from uneven heating of the food and low cooking efficiency. Therefore, the microwave rice cooker was invented, primarily utilizing the penetrating properties of microwaves to directly heat the water inside the pot and the food, offering advantages such as even and rapid heating.
[0030] In related technologies, microwave rice cookers use microwave-transparent inner pots such as glass or ceramic, and employ a metal cavity to house the inner pot. The inner pot protrudes from the cavity. Generally, the volume of the metal cavity is larger than that of the inner pot. When the inner pot is placed inside the metal cavity, it may deviate from the center of the metal cavity. Therefore, when the lid is closed, there is a possibility of collision with the protruding part of the inner pot. Furthermore, since microwave rice cookers use microwave-transparent inner pots such as glass or ceramic, they are more easily damaged, affecting the user experience.
[0031] In view of this, and in response to the problem that existing microwave rice cookers are prone to collision between the lid and the inner pot during the closing process, resulting in damage to the inner pot, this utility model proposes a microwave cooking appliance 100, which aims to improve the problem of collision between the lid and the inner pot.
[0032] The specific structure of the microwave cooking appliance 100 of this utility model will be described below:
[0033] Please refer to Figures 1 to 5This utility model proposes a microwave cooking appliance 100, which includes a pot body 10 and a lid 20. The pot body 10 includes a cavity 12 and an inner pot 13. The inner pot 13 is a microwave-permeable device. The cavity 12 has an opening 121. The inner pot 13 is detachably disposed in the cavity 12. When the inner pot 13 is placed in the cavity 12, the opening end of the inner pot 13 is higher than the opening 121 of the cavity 12. The lid 20 covers the opening 121 of the cavity 12, and the upper side of the lid 20 facing the cavity 12 is recessed to form a receiving groove 21. The opening end of the inner pot 13 is located in the receiving groove 21. One of the outer wall of the inner pot 13 or the inner wall of the cavity 12 is provided with a protruding limiting part 132, and the other is provided with a mating part 24 that abuts against the limiting part 132.
[0034] Specifically, the lid 20 is connected to the pot body 10, and the connection method can be a rotatable connection or a detachable connection. The cavity 12 is used to mate with the lid 20 of the microwave cooking appliance 100 to form a closed cavity to prevent microwave leakage; the inner pot 13 is used to hold food and heat it.
[0035] In one embodiment, the lid 20 is rotatably connected to the pot body 10, and the lid 20 can be unlocked by pressing a button. During the locking process, the lid 20 will gradually approach the inner pot 13, and finally the lid 20 will close at the opening 121 of the cavity 12, at which time the opening end (protruding part) of the inner pot 13 is located in the receiving groove 21.
[0036] The surface of the cavity 12 has an opening 121, allowing the inner liner 13 to be directly placed into or removed from the cavity 12. Therefore, the opening of the inner liner 13 is positioned higher than the opening 121 of the cavity 12. When the inner liner 13 is placed inside the cavity 12, it may deviate from the center of the cavity 12. A limiting part 132 and a mating part 24 are provided between the outer wall of the inner liner 13 and the inner wall of the cavity 12 to abut against each other, thus limiting the inner liner 13 and ensuring it returns to the correct position. When the lid 20 is closed, it gradually approaches the inner liner 13, preventing collisions and damage to the inner liner 13, and improving the user experience.
[0037] The limiting part 132 can be a positioning rib, positioning protrusion, positioning ring or positioning post, etc., and the mating part 24 can be a positioning plane, inclined surface or concave surface, etc. The specific form is not limited, as long as it can limit the position of the inner liner 13 in the cavity 12.
[0038] Therefore, the inner liner 13 is confined within the cavity 12 by the engagement of the limiting part 132 and the mating part 24, ensuring that the inner liner 13 is positioned correctly. This ensures that the inner liner 13 remains in the correct position during the closing process and throughout the entire use process, and prevents the inner liner 13 from moving. Even if the volume of the metal cavity 12 is larger than that of the inner liner 13, the position of the inner liner 13 is limited after placement, ensuring that the inner liner 13 will eventually return to the correct position regardless of how it is placed. This improves the accuracy of the inner liner 13's positioning, enhances the precision of the engagement between the lid 20 and the inner liner 13, and prevents collisions between the protruding parts of the lid 20 and the inner liner 13 during the closing process. This reduces the risk of damage to the inner liner 13 due to improper placement and also prevents the seal between the lid 20 and the inner liner 13 from failing.
[0039] The microwave rice cooker uses a microwave-transparent inner pot 13 made of glass or ceramic. By preventing unnecessary collisions between the inner pot 13 and the lid 20, the lifespan of the inner pot 13 is extended. During the cooking process, especially when opening and closing the lid, the inner pot 13 can also be prevented from moving due to external forces, avoiding collisions between the inner pot 13 and the cavity 12. At the same time, the sealing ring 23 on the lid 20 can seal the inner pot 13, preventing steam from escaping from the inner pot 13.
[0040] This utility model's technical solution provides a limiting part 132 and a mating part 24 between the outer wall of the inner liner 13 and the inner wall of the cavity 12 to confine the inner liner 13 within the cavity 12, ensuring that the inner liner 13 is placed in the correct position. This ensures that the inner liner 13 remains in the correct position during the closing process and throughout use, preventing it from moving. Therefore, even if the volume of the metal cavity 12 is larger than that of the inner liner 13, limiting the inner liner 13 after placement improves the accuracy of its positioning, enhances the precision of the latching between the lid 20 and the inner liner 13, and prevents collisions between the lid 20 and the protruding parts of the inner liner 13 during closing. This reduces the risk of damage to the microwave-transparent inner liner 13 and improves the user experience.
[0041] In an embodiment of this utility model, the distance between the outer wall of the inner liner 13 near the opening 121 and the inner wall of the corresponding cavity 12 is D1, and the distance between the outer wall of the inner liner 13 away from the opening 121 and the inner wall of the corresponding cavity 12 is D2, satisfying the relationship: D1 < D2.
[0042] In detail, by setting the limiting part 132 to cooperate with the mating part 24, the distance between the outer wall of the inner pot 13 near the opening 121 and the inner wall of the cavity 12 is set to be short. After the inner pot 13 is placed into the cavity 12, the inner pot 13 can be limited here to ensure that the inner pot 13 is correctly placed, reduce the risk of collision between the inner pot 13 and the lid 20, and prevent the inner pot 13 from moving due to vibration or improper operation during use. This makes the inner pot 13 more stable during cooking and can maintain good cooking results.
[0043] The relationship D1 < D2 must be satisfied. The specific structure to achieve this can be configured by setting a positioning part on the inner liner 13, or by setting a positioning part on the inner circumferential surface of the cavity 12. The positioning part can take the form of a positioning rib, a positioning block, a guide rail, etc. The specific structure can be selected according to actual needs.
[0044] In some embodiments, the distance D1 ranges from 2mm to 5mm.
[0045] Specifically, setting a certain gap can prevent the inner liner 13 from contacting the cavity 12 too tightly, avoiding excessive friction or collision between the inner liner 13 and the cavity 12. At the same time, by setting an appropriate distance, it can be ensured that there is enough space between the inner liner 13 and the cavity 12 during the heating process, so that microwaves can be evenly transmitted to all parts of the inner liner 13, improving heating efficiency. The inner liner 13 is also easier to remove and place, reducing the difficulty of cleaning and making it easier to clean and maintain the inner liner 13.
[0046] In an embodiment of this utility model, the inner liner 13 includes a liner body 131 and a limiting part 132, wherein the limiting part 132 is arranged around the outer wall of the liner body 131.
[0047] It is worth noting that, such as Figure 3 A limiting part 132 is provided on the outer wall of the inner liner body 131, and a mating part 24 is provided on the inner wall of the cavity 12. The limiting part 132 reduces the gap between the inner liner body 131 and the cavity 12. The distance between the outer wall of the limiting part 132 and the corresponding inner wall of the cavity 12 is D1. With the limiting part 132 on the inner liner body 131, the inner liner 13 is inserted smoothly. After insertion, the limiting part 132 and the mating part 24 abut against each other to limit the placement and ensure that the inner liner 13 is correctly placed. That is, when placing the inner liner 13, it can be quickly positioned by the abutment of the limiting part 132 and the mating part 24. When closing the lid, it prevents the lid 20 from directly hitting the inner liner 13 and avoids damage to the inner liner 13.
[0048] The cross-sectional shape of the limiting part 132 can be set according to actual needs, and can be set as trapezoidal, arc-shaped, or rectangular, etc. The mating part 24 can be the inner wall of the cavity 12 directly, or a mating plane can be protruded on the inner wall of the cavity 12 to abut against the limiting part 132.
[0049] Furthermore, the limiting part 132 is arranged circumferentially around the outer wall of the inner liner body 131. By providing uniform support in the circumferential direction, the limiting part 132 better limits and fixes the inner liner 13 within the cavity 12. By limiting and abutting with the mating part 24, it can prevent the inner liner 13 from shaking or shifting during use, enhance stability, reduce improper movement or collision of the inner liner 13, and thus improve the accuracy of positioning.
[0050] Meanwhile, the protruding limiting part 132 can also serve as a handle. By gripping the limiting part 132, the inner liner 13 can be taken out and placed more easily, allowing users to easily take out the inner liner 13 during cleaning and further improving the user experience.
[0051] In an embodiment of this utility model, the outer wall of the limiting part 132 is provided with a guide slope 1321, and the circumference of the guide slope 1321 gradually increases from the opening end of the inner liner 13 toward the bottom wall of the inner liner 13.
[0052] In detail, such as Figure 1 and Figure 2 The lid 20 and the pot body 10 are rotatably connected. During the closing process, the movement trajectory of the lid 20 is arc-shaped. Therefore, a guide slope 1321 is provided on the limiting part 132 to avoid the lid 20 from colliding with it during the closing process. The design of the guide slope 1321 ensures that when the lid 20 is pressed down to close, it can smoothly pass through the limiting part 132 without colliding with it, protecting the inner pot 13 from damage, improving safety, and enhancing the user experience. At the same time, the design of the guide slope 1321 also makes the inner pot 13 look more streamlined and harmonious, enhancing the aesthetics of the product.
[0053] In addition, such as Figure 3 The side wall of the limiting part 132 forms a guide slope 1321, and the bottom surface of the limiting part 132 forms a horizontal surface, which can be used as a handle to make it more convenient to take out and put in the inner liner 13.
[0054] In an embodiment of this utility model, the limiting part 132 further includes a positioning sealing ring 14, which is arranged around the inner wall of the cavity 12, and the inner ring of the positioning sealing ring 14 is used to abut against the mating part 24 of the inner liner 13.
[0055] In detail, a positioning sealing ring 14 is also provided, which can reduce the distance between the opening 121 of the cavity 12 and the outer wall of the inner liner 13, thereby positioning the inner liner 13 and preventing the sealing failure between the cover 20 and the inner liner 13 due to misalignment of the inner liner 13, thus improving the structural reliability and process feasibility of the cavity 12. In one embodiment, the distance between the positioning sealing ring 14 and the corresponding outer wall of the inner liner 13 is smaller than the distance between the inner wall of the cavity 12 away from the opening 121 and the corresponding outer wall of the inner liner 13.
[0056] Because the positioning sealing ring 14 is made of a relatively soft material, after the inner liner 13 is placed, the positioning sealing ring 14 can support the mating part 24 of the inner liner 13, thereby preventing the inner liner 13 from colliding and being damaged with the cavity 12, and also preventing the inner liner 13 from colliding and being damaged with the cover 20, thus protecting the inner liner 13 well.
[0057] In an embodiment of this utility model, the circumference of the inner wall of the cavity 12 gradually decreases from the opening 121 toward the end away from the opening 121.
[0058] Specifically, the inner wall circumference of the end of the cavity 12 away from the opening 121 is designed to be smaller. After the inner liner 13 is placed in the cavity 12, the bottom wall of the cavity 12 limits the bottom of the inner liner 13. At the same time, the positioning sealing ring 14 limits the opening end of the inner liner 13 to better maintain the position of the inner liner 13 in the cavity 12. During the closing process, it prevents the lid 20 from colliding with the inner liner 13 and causing damage to the inner liner 13.
[0059] Meanwhile, the cavity 12 has a wide opening 121 and a shallow bottom, meaning that the inner liner 13 can be well aligned with the opening 121 of the cavity 12 when placed, and can be inserted relatively smoothly through the opening 121. The inner circumferential surface of the cavity 12 has an incline. By gradually changing the size of the cavity 12, the distance between the inner liner 13 and the cavity 12 is gradually reduced, which can guide the inner liner 13 to move continuously towards the center of the cavity 12. After the inner liner 13 is placed, it returns to the correct position.
[0060] In an embodiment of this utility model, the inner ring of the positioning sealing ring 14 has a guiding slope 141, and the circumference of the guiding slope 141 gradually decreases from the opening 121 of the cavity 12 toward the bottom wall of the cavity 12.
[0061] It is worth noting that the design of the guide slope 141 can reduce the friction between the inner liner 13 and the positioning sealing ring 14 when it is inserted or removed. As the inner liner 13 is inserted deeper, the guide slope 141 gradually narrows, which can better form a tight contact with the inner liner 13, prevent the inner liner 13 from colliding with the cavity 12, and at the same time effectively limit and fix the inner liner 13. This makes it easier and more convenient for users to use, reduces the trouble when placing the inner liner 13, and improves the overall user experience.
[0062] In embodiments of this utility model, the inner liner 13 is a glass or ceramic component.
[0063] It is worth noting that the inner pot 13 is made of microwave-permeable materials such as glass or ceramic, which allows microwaves to penetrate the inner pot 13 more evenly, thereby achieving uniform heating of food, which helps to improve the cooking effect and ensures that the inside and outside of the food are properly treated.
[0064] In an embodiment of this utility model, the cover 20 includes a microwave shielding cover 22, which is a metal part. The microwave shielding cover 22 forms the receiving groove 21. A shielding surface is provided at the opening 121 of the cavity 12, and the microwave shielding cover 22 abuts against the shielding surface.
[0065] Specifically, metal materials can effectively reflect and block microwaves. By designing the microwave shielding cover 22 as a metal part and making it in close contact with the shielding surface, it can be ensured that microwaves will not leak out from the gap between the microwave shielding cover 22 and the cavity 12, thus protecting the user's safety. Furthermore, the microwaves are confined within the cavity 12, reducing energy loss and enabling microwaves to be used more efficiently to heat food, improving cooking efficiency and saving energy.
[0066] In an embodiment of this utility model, the bottom wall of the receiving groove 21 is provided with a sealing ring 23 for sealing against the opening end of the inner liner 13.
[0067] In detail, such as Figure 4 The sealing ring 23 abuts against the opening end of the inner pot 13. The sealing ring 23 can effectively prevent the liquid generated during cooking from leaking out from the gap between the inner pot 13 and the lid 20, and helps to maintain the temperature and pressure inside the inner pot 13, so that the heat is more concentrated on the food and the heating efficiency is improved.
[0068] The sealing ring 23 can also reduce or prevent steam from escaping, which not only helps maintain the internal temperature, but also better retains the moisture in the food, making the food more delicious and protecting the user from the risk of being scalded by hot steam.
[0069] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
