Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooking utensils, in particular to a cooking utensil. BACKGROUND

[0002] In modern families and office places, microwave ovens become common cooking utensils because of their convenience, high efficiency and low price. The mainstream microwave system of microwave ovens on the market generally contains a waveguide structure. Its working principle is that a microwave generator generates microwaves, and then the microwaves are transmitted to a cooking cavity by a waveguide to heat food. For example, as shown in Figures 10 to 13 , one kind of structure is to guide the microwaves generated by a side-mounted magnetron 3' into the bottom of the cavity and feed them into a cooking cavity 1' (as shown in Figure 10 and Figure 11 ) through a waveguide 2'. This kind of scheme causes the waveguide 2' to absorb more microwaves due to the long waveguide 2', resulting in reduced heating efficiency. In order to ensure the uniformity of food heating, a rotating device (stirring blade 4') is often provided to disperse the microwaves. Another kind of structure is to guide the microwaves from a bottom-mounted magnetron 3' into the bottom of the cavity through an L-shaped waveguide 2' (as shown in Figure 12 and Figure 13 ). However, this structure is complex, resulting in high manufacturing cost. The above-mentioned related technologies have many disadvantages. The existence of the waveguide structure not only causes the main body of the microwave oven to vibrate and produce noise due to electromagnetic excitation, but also increases the number of parts of the microwave oven, resulting in increased production cost and reduced assembly efficiency, and also reduces the heating efficiency.

[0003] Therefore, how to design a cooking utensil without a waveguide structure to enable the microwave source to directly heat in the cooking cavity to improve the heating efficiency and reduce the production cost has become a problem to be solved at present. SUMMARY

[0004] The utility model aims at least solve the problem of low heating efficiency and high production cost of microwave ovens.

[0005] Therefore, the first aspect of the utility model provides a cooking utensil.

[0006] Therefore, the first aspect of the utility model provides a cooking utensil.

[0007] The cooking utensil provided by the utility model, which comprises a box body, a microwave feeding inlet and a microwave generator. The box body is provided with a cooking cavity and a microwave feeding cavity. The cooking cavity and the microwave feeding cavity are correspondingly arranged. The microwave in the microwave feeding cavity can act on the cooking cavity to cook the food in the cooking cavity. The microwave feeding inlet is arranged on the box body and can communicate the microwave feeding cavity of the box body with the outside of the box body. In this way, the microwave output end of the microwave generator can be communicated with the microwave feeding cavity through the microwave feeding inlet to transmit the microwave to the microwave feeding cavity, thereby realizing the cooking of the food in the cooking cavity. It can be understood that the microwave output end is directly communicated with the microwave feeding cavity in the present application, and no waveguide pipe or other structure is needed, thereby reducing the microwave transmission path and the energy loss in the microwave transmission process, thereby effectively improving the heating efficiency of the cooking utensil and enabling the food to be cooked to the ideal state in a shorter time. Secondly, due to the absence of a complex waveguide structure, the vibration of the box body caused by electromagnetic excitation is greatly reduced, and the noise generated in the cooking process is significantly reduced, thereby creating a more quiet and comfortable cooking environment for the user. Furthermore, the number of parts is reduced, which not only reduces the production cost but also improves the assembly efficiency in the production and assembly process, is conducive to large-scale production and manufacturing, and can improve the market competitiveness of the product while ensuring the performance of the product.

[0008] According to the cooking utensil provided by the utility model, the following additional technical features can also be provided.

[0009] In some embodiments, optionally, the box body comprises: a cooking part, the cooking cavity being arranged in the cooking part; a microwave feeding part, connected with the cooking part, the microwave feeding cavity being arranged in the microwave feeding part, the microwave feeding inlet being arranged in the microwave feeding part, the microwave feeding part being recessed inwardly of the cooking cavity or protruding outwardly of the cooking cavity; and wherein the cooking part and the microwave feeding part are of an integrated structure or a split structure.

The microwave feeding inlet is arranged in the microwave feeding part, and the microwave feeding part can be recessed inwardly of the cooking cavity or protrude outwardly of the cooking cavity, that is, the microwave feeding part can protrude the cooking part in the direction close to or away from the cooking cavity. Such a design makes the microwave transmission between the microwave feeding cavity and the cooking cavity more direct and efficient, further improving the cooking efficiency. The cooking part and the microwave feeding part can be of an integrated structure, facilitating overall manufacturing and installation, or can be of a split structure, facilitating assembly and adjustment according to actual needs, increasing the flexibility and adaptability of the product.

[0011] In some embodiments, optionally, the microwave feeding cavity is a recessed part formed by recessing part of the wall surface of the box body outwardly of the cooking cavity or inwardly of the cooking cavity.

[0012] In the embodiments, the microwave feeding cavity can be arranged as a part of the wall of the box, and the microwave feeding cavity is recessed outward of the cooking cavity or recessed inward of the cooking cavity, and the microwave feeding port is arranged in the recessed portion. In this way, the microwave feeding cavity of the box is in communication with the outside of the box, so that the microwave output end of the microwave generator is in communication with the microwave feeding cavity through the microwave feeding port, so as to cook the food in the cooking cavity. This design enables the microwave output end of the microwave generator to be more directly in communication with the microwave feeding cavity, further shortens the microwave transmission path, reduces the energy loss of the microwave in the transmission process, and effectively improves the heating efficiency of the cooking appliance, so that the food can be cooked to the desired state in a shorter time.

Such an arrangement can effectively change the incident angle and direction of the microwave entering the cooking cavity, so that the reflection and distribution of the microwave in the cooking cavity are more uniform, and the situation of local overheating or uneven heating is avoided, which significantly improves the consistency and stability of the cooking effect, so that the food in the cooking cavity can be supplied with appropriate microwave energy at each position, thereby cooking food with higher quality and better taste. At the same time, since the top wall of the recessed portion has an angle with the axis of the microwave feeding port, that is, the top wall is arranged obliquely, when other parts are arranged outside the recessed portion, the connection between the other parts and the recessed portion is facilitated.

[0015] In some embodiments, optionally, the inclination angle of the top wall of the recessed portion is less than or equal to 5°.

[0016] In some embodiments, optionally, the inclination angle of the bottom wall of the recessed portion is greater than or equal to 30°.

[0026] In the embodiments, the U-shaped plate comprises oppositely arranged first and second sub-plates, and the recesses can be arranged on the first and / or second sub-plates, so that structures corresponding to the recesses can be arranged on the first or second sub-plate without the recesses to improve the microwave diffusion effect.

[0027] In some embodiments, optionally, the U-shaped plate is a stamping part.

[0028] In the embodiments, the stamping process has high forming precision of the U-shaped plate and the recesses, and can ensure the position accuracy and size consistency of the microwave feed inlet and related structures on the cabinet, thereby ensuring the precision and stability of the microwave transmission path, effectively improving the microwave energy transmission efficiency, and making the heating performance of the cooking appliance more reliable.

[0034] In the embodiments, the microwave generator comprises a magnetron, and a microwave output end of the magnetron extends into the microwave feeding cavity through the microwave feeding port. By limiting the microwave generator to only include the magnetron, the microwave generated by the magnetron can be directly fed into the microwave feeding cavity without passing through a waveguide or the like, so that the loss of microwave can be avoided, and the heating efficiency can be improved.

When the microwave feeding cavity is in communication with the cooking cavity, the cover plate can be arranged to seal the microwave feeding cavity, so as to prevent food in the cooking cavity from splashing into the microwave feeding cavity, or prevent the microwave in the microwave feeding cavity from diffusing out of the cooking cavity. It can be understood that the cover plate is made of a material capable of conducting microwave, so as to ensure that the microwave can be normally introduced into the cooking cavity. When the recess is recessed from the wall surface of the box towards the cooking cavity, the cover plate is arranged outside the cooking cavity to seal the opening of the recess. At this time, the cover plate needs to be made of a material incapable of conducting microwave, so as to ensure that the microwave does not leak out of the cooking cavity.
