Description

Technical Field

[0001] The utility model relates to the field of microwave ovens, and more specifically, to a vehicle-mounted microwave oven. Background Art

[0002] In modern travel, vehicle-mounted microwave ovens have brought great convenience to us, allowing us to enjoy hot food at any time during the journey. However, for current vehicle-mounted microwave ovens, there are still some drawbacks that cannot be ignored.

[0003] Firstly, there is the problem of occupying space. Existing vehicle-mounted microwave ovens generally have a relatively large volume and appear rather obtrusive in the already limited vehicle interior space. This poses a significant burden on the storage space of some small vehicles.

[0004] Secondly, existing vehicle-mounted microwave ovens cannot effectively cool the water vapor generated during food heating. When we use a microwave oven to heat food, a large amount of water vapor is inevitably generated. However, due to the lack of corresponding cooling devices in current vehicle-mounted microwave ovens, this water vapor will fill the interior of the microwave oven, which may not only affect the normal operation of the microwave oven and shorten its service life, but also may gush out in large quantities the moment the oven door is opened, increasing the humidity inside the vehicle and even condensing into water droplets on the car window, affecting the driver's line of sight and posing a potential hazard to driving safety. Content of the Utility Model

[0005] To solve the above problems, the utility model provides a vehicle-mounted microwave oven, which includes a microwave heating device and a furnace body. The microwave heating device is arranged at the bottom of the furnace body. The furnace body includes a furnace cavity and a furnace cover. One end of the furnace cavity is in contact with the microwave heating device, and the furnace cover covers the other end of the furnace cavity. An air vent pipe is spirally arranged from high to low inside the furnace cover. One end of the air vent pipe is arranged at the bottom of the furnace cover and communicates with the furnace cavity, and the other end is arranged at the top of the furnace cover and communicates with the outside.

[0006] Furthermore, the air vent pipe includes a rising part and a spiral part that are interconnected. The rising part is arranged between the bottom of the furnace cover and the highest point of the furnace cover, and the spiral part is arranged around the rising part in a downward spiral from the highest point of the furnace cover.

[0007] Furthermore, the inner diameter of the spiral part of the air vent pipe gradually decreases from high to low.

[0008] Furthermore, the air vent pipe forms an air inlet at the bottom of the furnace cover. The air inlet is arranged in the middle of the bottom of the furnace cover and is connected to the rising part. The air vent pipe forms an air outlet at the edge of the top of the furnace cover, and the air outlet is connected to the spiral part.

[0009] Furthermore, a partition is provided at the bottom of the furnace cover, and a plurality of ventilation openings are provided on the partition.

[0010] Furthermore, the furnace cavity includes a metal outer shell layer disposed on the outermost layer, a heat insulation layer sleeved inside the metal outer shell layer, and an inner liner sleeved inside the heat insulation layer.

[0011] Furthermore, the material of the heat insulation layer is asbestos or fiberglass, and the material of the inner liner is aluminum or stainless steel.

[0012] Furthermore, a container for holding food is provided inside the furnace cavity.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In this application, the microwave heating device is first disposed at the bottom of the furnace body. In a relatively small space such as inside a vehicle, the space utilization rate can be maximized. At the same time, the bottom is flat without sanitary dead corners, and it is relatively simple to clean, and there are no difficult-to-clean parts such as the gap between the turntable and the bottom.

[0029] 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 this utility model belongs. The terms used in this specification in the description of the utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0030] 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.

[0031] Now, with reference to the accompanying drawings, a preferred embodiment of the present utility model will be further described. An in-vehicle microwave oven, as shown in Figure 1 and Figure 2 includes a microwave heating device 10 and a furnace body 20. The microwave heating device 10 is disposed 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. The furnace cover 200 covers the other end of the furnace cavity 100. An air vent pipe 210 is spirally disposed in the furnace cover 200 from high to low. One end of the air vent pipe 210 is disposed at the bottom of the furnace cover 200 and communicates with the furnace cavity 100, and the other end is disposed at the top of the furnace cover 200 and communicates with the outside.

[0032] During the process of gradually heating the food in the furnace body 20 by the microwave heating device 10, steam is gradually generated as the food in the furnace body 20 is heated. The steam enters the air vent pipe 210 through the bottom of the furnace cover 200. Since the air vent pipe 210 in the furnace cover 200 is spirally disposed from high to low, the total travel of the air vent pipe 210 is elongated inside the furnace cover 200. Therefore, the steam will be cooled for a long time in the air vent pipe 210, and finally the steam flowing out from the top of the furnace cover 200 is usually at a low temperature. Compared with the prior art, in the present application, the microwave heating device 10 is disposed at the bottom of the furnace body 20. In this way, in a relatively small space inside the vehicle, the space utilization rate can be maximally improved. At the same time, the bottom is flat and there are no sanitary dead corners, and it is relatively simple to clean, and there are no difficult-to-clean parts such as the gap between the turntable and the bottom. Secondly, in the present application, the spiral air vent pipe 210 is disposed in the cover body to cool the steam. In this way, in a closed space inside the vehicle, the impact on the vehicle occupants, such as scalding, can be maximally avoided.

[0033] Furthermore, in the above-mentioned embodiment, as shown in Figure 3As shown, the ventilation duct 210 includes a rising portion 211 and a spiral portion 212 that are interconnected. The rising portion 211 is disposed between the bottom of the furnace cover 200 and the highest point of the furnace cover 200. The spiral portion 212 is disposed around the rising portion 211 in a downwardly surrounding manner from the highest point of the furnace cover 200. In this way, when steam enters the ventilation duct 210 from the furnace chamber 100, it will first pass through the rising portion 211 to reach the highest point of the furnace cover 200, and then pass through the spiral portion 212 from the highest point of the furnace cover 200 for long-term cooling, and finally flow out from the top of the furnace cover 200. In this way, the space and structure inside the furnace cover 200 can be fully utilized to play a role in cooling the steam.

[0034] Furthermore, in the above-described embodiment, in combination with Figure 2 and Figure 3 As shown, the inner diameter of the spiral portion 212 of the ventilation duct 210 gradually decreases from high to low. In this way, the diameter of the spiral portion 212 of the ventilation duct 210 gradually becomes thinner from high to low. Since the flow rate of the gas is equal to the flow velocity multiplied by the cross-sectional area, that is, Q = U * A (Q is the flow rate, U is the flow velocity, and A is the cross-sectional area). In an incompressible and steady fluid, the mass of the fluid flowing through each cross-section of the duct is equal. When the cross-sectional area of the duct becomes smaller (the duct becomes thinner), in order to keep the volume of the fluid flowing through per unit time unchanged, the flow velocity will increase accordingly. Therefore, the flow velocity of the steam in the ventilation duct 210 will increase, thereby further enhancing the cooling effect of the steam in the ventilation duct 210.

[0035] Furthermore, in the above-described embodiment, as Figure 4 shown, the ventilation duct 210 forms an air inlet 220 at the bottom of the furnace cover 200. The air inlet 220 is disposed in the middle of the bottom of the furnace cover 200 and is connected to the rising portion 211 of the air inlet 220. Since the distance between the middle of the bottom of the furnace cover 200 and the highest point of the furnace cover 200 is the shortest, in this way, the steam can reach the highest point of the furnace cover 200 more quickly after passing through the air inlet 220 from the furnace chamber 100. The ventilation duct 210 forms an air outlet 230 at the edge of the top of the furnace cover 200. The air outlet 230 is connected to the spiral portion 212. In this way, the steam finally flows out to the outside from the air outlet 230 during the continuous cooling process in the spiral portion 212.

[0036] Furthermore, in the above-described embodiment, as Figure 2 shown, a partition plate 240 is further disposed at the bottom of the furnace cover 200, and a plurality of ventilation openings 241 are disposed on the partition plate 240, which can avoid microwave leakage and achieve preliminary temperature reduction.

[0037] Furthermore, in the above-described embodiment, as Figure 5As shown, the oven cavity 100 includes a metal outer shell layer 110 disposed at the outermost layer. The metal outer shell layer 110 mainly plays the role of protecting the internal structure, supporting and aesthetically pleasing. Since it is made of aluminum or stainless steel, it reflects the microwave rays emitted from the bottom, so that the food in the oven cavity 100 can be heated more evenly. A heat insulation layer 120 is sleeved inside the metal outer shell layer 110, and the heat insulation layer 120 is connected to the metal outer shell layer 110. Figure 5 and Figure 6 As shown, the function of the heat insulation layer 120 is to reduce the heat loss from the furnace to the outside, improve the heating efficiency, and also prevent the temperature outside the furnace from being too high to avoid scalding the user. An inner liner 130 is sleeved in the heat insulation layer 120 as a container for the overflowing soup after boiling. Preferably, the material of the metal outer shell layer 110 can be aluminum or stainless steel, the material of the heat insulation layer 120 can be asbestos, glass fiber or mica board, and the material of the inner liner 130 can be glass.

[0038] In the above embodiment, a container 140 for holding food is provided in the oven cavity 100. Since the inner pot 130 is usually not suitable for direct contact with food, the container 140 is provided in the oven cavity 100. It can be used to place food. Preferably, the material of the container 140 can be ceramic, and the characteristics of the material can be utilized to make it have excellent heat preservation properties, which is suitable for stewing and braising.

[0039] The above exemplary embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
