[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0027] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] Now, with reference to the drawings, a further description of the preferred embodiments of the present utility model will be given. In combination with Figure 1 and Figure 2As shown in the figure, a microwave oven for vehicle use includes a microwave heating device 10 and a furnace body 20. The microwave heating device 10 is arranged at the bottom of the furnace body 20. The furnace body 20 includes a furnace cavity 100 and a furnace cover 200. The furnace cavity 100 is used for placing food to be heated. One end of the furnace cavity 100 is in contact with the microwave heating device 10, and the furnace cover 200 covers the other end of the furnace cavity 100. The furnace cavity 100 includes a metal outer shell layer 110, a heat insulation layer 120, and an inner container 130 which are arranged in sequence from outside to inside. Compared with the prior art in this application, during the process of the microwave heating device 10 heating the bottom of the furnace body 20, the overall volume can be controlled to be very small. By setting the metal outer shell layer 110, it mainly plays the roles of protecting the internal structure, providing support and appearance. At the same time, since the microwave heating device 10 is arranged at the bottom of the furnace cavity 100, setting the metal outer shell layer 110 can reflect the microwave rays emitted from the bottom, so that the food in the furnace cavity 100 can be heated more evenly. Meanwhile, setting the heat insulation layer 120 can reduce the heat dissipation from the furnace to the outside, improve the heating efficiency, prevent the temperature outside the furnace from being too high, and avoid scalding the user. And setting the inner container 130 can be used as a container to hold the soup overflowing after boiling.

[0029] Furthermore, on the basis of the above-mentioned embodiment, as Figure 3 shown, a bending part 131 is arranged at the top of the inner container 130. The bending part 131 bends towards the metal outer shell layer 110 at the top of the inner container 130 and closes the top of the heat insulation layer 120. In this way, when the liquid food in the furnace cavity 100 overflows in the boiling state, since the bending part 131 closes the top of the heat insulation layer 120 at the top of the inner container 130, it can prevent the overflowing food from flowing into the heat insulation layer 120, thereby causing damage to the heat insulation layer 120.

[0030] Furthermore, on the basis of the above-mentioned embodiment, as Figure 5 shown, the furnace cover 200 is of a hollow structure. An air inlet 210 is formed at the bottom of the furnace cover 200. The air inlet 210 is arranged in the middle of the bottom of the furnace cover 200. An air outlet 220 is formed at the edge of the top of the furnace cover 200. In this way, the steam in the furnace cavity 100 can enter the inside of the furnace cover 200 through the air inlet 210 at the bottom of the furnace cover 200, be cooled inside the furnace cover 200, and then flow out to the outside through the air outlet 220.

[0031] Furthermore, on the basis of the above-mentioned embodiment, in combination with Figure 2 and Figure 4 shown, a partition plate 300 is further arranged at the bottom of the furnace cover 200. A plurality of air vents 310 are arranged on the partition plate 300. The partition plate 300 is used to prevent microwave leakage and achieve preliminary cooling.

[0032] In some embodiments, the material of the heat insulation layer 120 is asbestos, fiberglass or mica plate. Asbestos is a mineral fiber material with a high melting point and low thermal conductivity. Its heat insulation effect mainly stems from the fact that its fiber structure can hinder the conduction of heat. There are a large number of tiny voids between asbestos fibers, and these voids are filled with air. Air is a poor heat conductor and can effectively prevent the transfer of heat. Fiberglass and mica plate are also fibrous materials, and their heat insulation principle is similar to that of asbestos. There are also a large number of tiny voids between fiberglass fibers, and the air in these voids can hinder the conduction of heat.

[0033] In some embodiments, the material of the metal outer shell layer 110 is aluminum or stainless steel. There are a large number of freely movable electrons inside aluminum and stainless steel. Under the action of the microwave electric field, these free electrons will oscillate violently. This oscillation will generate an electromagnetic field opposite to the incident microwave, thus causing the microwave to be reflected back.

[0034] In some embodiments, the material of the inner container 130 is glass, and it can be used as a container for holding the soup overflowing after boiling.

[0035] In some embodiments, as Figure 2 shown, a ring-shaped groove 132 is provided at the bottom of the inner container 130, and the soup and grease overflowing from the inner container 130 can be concentrated in the groove 132, so as to avoid affecting the transmission of microwaves.

[0036] Furthermore, in the above-mentioned embodiments, as Figure 4 shown, a utensil 400 for holding food is provided in the furnace cavity 100. Therefore, the utensil 400 is provided in the furnace cavity 100. It can be used to place food. Preferably, the material of the utensil 400 can be ceramic, and its excellent heat preservation property can be utilized, which is suitable for stewing, simmering and braising.

[0037] Details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
