Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to a vacuum microwave oven. Background Technology

[0002] A microwave-steam oven is a device that integrates microwave heating, heating element baking, and steaming functions. It is primarily used in household appliances and can also be used in industrial settings under certain conditions. Currently, it is favored by consumers due to its ability to achieve more diverse cooking methods. However, with the increase in functions, operation has become more complex. Numerous function buttons require setting specific parameters for each function and each type of food, making it inconvenient to use. Furthermore, practical experience has shown that existing microwave-steam ovens are less effective with dough products that haven't fermented properly (such as bread). Additionally, if roasted meat is stored and then reheated, it loses significant moisture, resulting in a very dry texture, making it impossible to consistently produce delicious roasted meat. Utility Model Content

[0003] This invention provides a vacuum microwave oven to solve the technical problems of existing microwave ovens, such as poor proofing, excessive moisture loss during baking, and inconvenient operation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A vacuum microwave oven is designed, comprising a cabinet and an inner liner. A microwave mechanism, a steaming mechanism, and a baking mechanism are disposed between the cabinet and the inner liner, and a vacuum mechanism is also included. A receiving cavity is provided on one side of the cabinet, and the vacuum mechanism is disposed in the receiving cavity. The vacuum mechanism includes a vacuum pump. An air vent communicating with the vacuum pump is provided on the inner liner. A control panel is provided on the cabinet, and the control panel is electrically connected to the microwave mechanism, the steaming mechanism, the baking mechanism, and the vacuum mechanism.

[0006] Furthermore, a vacuum tube is connected to the vacuum pump, and a vacuum cover is connected to the end of the vacuum tube. The vacuum cover is connected to the outside of the inner liner, and the inner liner has an array of air holes located at the position covered by the vacuum cover.

[0007] Furthermore, the microwave mechanism includes a magnetron disposed in the receiving cavity, and the magnetron is fixedly installed on the inner liner.

[0008] Furthermore, the steaming mechanism includes a correspondingly connected steam generator and a secondary heating pipe. The end of the secondary heating pipe is connected to a steam hood, and the inner liner is provided with an array of steam holes located at the position covered by the steam hood.

[0009] Furthermore, the secondary heating tube is a dry-burning heating tube and / or an electromagnetic heating tube, used to reheat the steam generated by the steam generator to produce superheated steam. The steam in the pipeline is reheated by the dry-burning heating tube or the electromagnetic heating tube to produce superheated steam. The magnetic induction coil and the dry-burning heating tube can be used alone or in combination to reheat the steam twice, producing higher temperatures to meet the needs of different scenarios.

[0010] Furthermore, the baking mechanism includes disc-shaped electric heating tubes disposed above and below the inner liner.

[0011] Furthermore, it also includes a rotating grill, which includes a first support plate at the first end, a second support plate at the second end, and a drive assembly connected to the first support plate. The drive assembly includes a clamping component and a power component for driving the clamping component to rotate.

[0012] Furthermore, the clamping component includes multiple columnar connecting parts, each connected part being provided with a clamping block, and the second support plate being provided with toothed grooves, the grooves being positioned corresponding to the connecting parts.

[0013] Furthermore, the power component includes meshing gears disposed on the connecting part and a motor that drives the gears to rotate.

[0014] Furthermore, the control panel is equipped with a barcode / QR code scanning module, a Bluetooth module, an NFC module, and a WIFI module.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] 1. In addition to having microwave steaming and baking functions, this utility model is also equipped with a vacuum system. When the vacuum system is working, it can evacuate the inside of the chamber, allowing the food to rise and expand at a lower temperature, thereby improving the problem that some foods (such as toast) do not expand or expand poorly when heated.

[0017] 2. This utility model can identify products by scanning QR codes or barcodes, or wirelessly connect to a mobile phone via Bluetooth / WIFI / NFC. The type of product to be processed can be set through the mobile phone, and the microwave / steaming / baking method and temperature / time parameters can be automatically matched to intelligently process the product, eliminating tedious manual operation steps and avoiding manual operation errors, thereby ensuring the quality of food processing.

[0018] 3. This utility model adds a superheated steam structure, which, together with a rotating grill, can treat the surface of the meat skewers with superheated steam to lock in moisture and nutrients, making them easy to store. After storage, reheating can produce grilled meat that is crispy on the outside and tender on the inside. Attached Figure Description

The power component includes meshing gears 904 on the connecting parts and a motor 905 that drives the gears to rotate. The motor 905 can be directly connected to the innermost gear 904, or it can be positioned below the gear 904 and connected via a transmission gear. The rotating grill 9 can also serve as a support component for steamers, baking trays, etc.

[0031] This utility model vacuum microwave oven can achieve the following cooking methods: (1) Microwave proofing: The magnetron generates microwaves to proof the surface, which is highly efficient. During the proofing process, the interior is vacuumed so that the food expands at a lower temperature, thereby improving the problem that some foods (such as bread) do not expand or expand poorly when heated. Steam can also be introduced to replenish moisture during the proofing process; (2) Microwave heating: Increasing the power of the microwave can realize the function of microwave heating food. At this time, vacuuming is not required; (3) Conventional steaming: Place the food in a steamer and introduce hot steam for steaming; (4) Conventional baking: Use two electric heating plates on the top and bottom to bake the food; (5) Superheated steam baking: Place the meat skewers on a rotating rack and introduce superheated steam to make the surface quickly brown, which helps to lock in moisture and nutrients. The taste will not be affected after storage and further processing.

[0032] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, those skilled in the art will understand that, without departing from the spirit of the present invention, various specific parameters in the above embodiments can be changed to form multiple specific embodiments, all of which are common variations of the present invention, and will not be described in detail here.
