Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and specifically to a layered steam oven. Background Technology

[0002] Currently, there are only a few food processing methods worldwide: frying, stir-frying, deep-frying, steaming, boiling, stewing, and roasting. Among these basic methods, steaming and roasting account for a considerable proportion, which shows people's preference for these two methods. For example, our most common staple foods, rice and steamed buns, are mainly steamed, while barbecue, such as grilled lamb skewers, is very popular now, which is inseparable from the roasting process. With economic development and social progress, people have higher demands for food variety, which in turn increases the requirements for food processing. Some food processing requires both steaming and baking, with some requiring steaming first and then baking, and others requiring baking first and then steaming. Simply using a steamer and a layered steam oven to complete these two processes results in disjointed operation and low efficiency. Moreover, the need to transfer food from one device to another can negatively impact food quality. Especially in today's increasingly market-oriented environment, any product requires high production efficiency. To improve production efficiency, companies have considered combining steaming and baking processes into one food processing device. This led to the development of the layered steam oven, which has seen continuous development in recent years and has become a commonly used kitchen appliance in modern kitchens.

[0003] However, the internal capacity of current steam ovens with layered steam is fixed. Even when heating small or easily cooked foods, the entire internal cavity needs to be heated, which consumes a lot of energy and is not conducive to rapid heating of food. Furthermore, when heating multiple foods, flavors can easily mix. In addition, since different types of food have different heating times and temperatures, they are usually heated in batches, which takes a lot of time. Utility Model Content

[0037] like Figure 1-8 As shown, a layered steam oven includes,

[0038] The box body 10 has an installation cavity inside, and an inner liner 101 is installed inside the installation cavity. The inner liner 101 has an opening on its side that communicates with the outside.

[0039] A lid 20 is rotatably mounted at one end to the opening;

[0040] A tray 30 is disposed inside the inner liner 101 and is adapted to divide the space inside the inner liner 101 into several heating chambers. A sealing element 301 is provided on the edge of the tray 30. The sealing element 301 is made of elastic material and is adapted to seal the gap between the tray 30 and the side wall of the inner liner 101 and between the tray 30 and the lid 20 under the pressure of the lid 20.

[0041] The support unit 40 includes a plurality of adjustable brackets 401 disposed on the side wall of the inner liner 101, and the tray 30 is disposed on the adjustable brackets 401 to adjust the height of the tray 30 inside the inner liner 101.

[0042] The heating unit 50 is connected to the heating cavity to heat the heating cavity.

[0043] This invention features an adjustable bracket 401 installed inside the inner liner 101, with a tray 30 mounted on the bracket 4012. The adjustable bracket 401 allows for adjustment of the tray 30's position within the inner liner 101 to accommodate heating different sized foods. Furthermore, an elastic sealing element 301 is provided at the edge of the tray. When the lid 20 is closed on the body 10, it compresses the tray 30, causing the sealing element 301 to deform and seal the gaps between the tray 30 and the side wall of the inner liner 101, as well as between the tray 30 and the lid 20. This divides the space inside the inner liner 101 into several independent heating chambers, eliminating the need for separate inner liners 101 or partition structures for each heating chamber. This maximizes the use of the space inside the inner liner 101 and prevents cross-contamination of flavors during heating.

[0044] Preferably, in this embodiment, the adjustable bracket 401 includes a fixed base 4011, a bracket 4012, and a locking member 4014. The fixed base 4011 is fixedly installed on the side wall of the inner liner 101. The fixed base 4011 has a sliding hole for the bracket 4012 to pass through. The bracket 4012 has a plurality of locking holes 4013 evenly provided along its length. The locking member 4014 is slidably installed on the fixed base 4011 and is adapted to move toward or away from the bracket 4012 under the action of external force. The locking member 4014 is provided with a locking block 4015 that matches the locking hole 4013, so as to be suitable for embedding into the locking hole 4013 when the locking member 4014 moves toward the bracket 4012. The top end of the bracket 4012 is provided with a support rod for supporting the tray 30.

[0045] In use, the user only needs to adjust the bracket 4012 to a suitable height, and then move the locking member 4014 toward the bracket 4012 so that the locking block 4015 on the locking member 4014 is inserted into the locking hole 4013 to lock the bracket 4012. When other adjustments are needed, simply pull the locking member 4014 outward so that the locking member 4014 moves away from the bracket 4012, and the locking block 4015 separates from the locking hole 4013. At this time, the bracket 4012 can slide freely up and down along the sliding hole, thereby adjusting the position of the tray 30 in the inner liner 101.

[0046] Meanwhile, since the card block 4015 expands after heating, in this embodiment, the card block 4015 and the card hole 4013 can be connected together by a clearance fit.

[0047] In addition, to prevent the locking member 4014 from coming loose after locking, in this embodiment, the adjustable bracket 401 also includes an elastic member 4016. One end of the elastic member 4016 is fixedly connected to the fixed base 4011, and the other end is fixedly connected to the locking member 4014, so as to provide the locking member 4014 with an elastic force to move toward the bracket 4012.

[0048] Furthermore, to facilitate user adjustment, in this embodiment, a chamfer is provided at the lower edge of one end of the card block 4015 that is embedded in the card hole 4013, and a bevel is provided at the lower edge of the card hole 4013 that matches the chamfer. In use, the user can push the bracket 4012 upward, and the bevel provided at the lower edge of the card hole 4013 will fit against the chamfer on the card hole 4013. The chamfer will slide along the bevel to separate the card block 4015 from the card hole 4013, so that the position of the bracket 4012 can be adjusted.

[0049] Preferably, in this embodiment, the heating unit 50 includes a water tank 501, a steam evaporator 502, a steam-water separator 503, and a connecting pipe 504 disposed within the housing 10. The steam evaporator 502 is connected to the water tank 501. A water pump is disposed within the water tank 501. The water pump is adapted to pump water from the water tank 501 into the steam evaporator 502. The steam evaporator 502 is connected to the steam-water separator 503. The inlet of the connecting pipe 504 is connected to the steam-water separator 503. The outlet of the connecting pipe 504 is connected to several heating chambers. A heating resistance wire is wound around the surface of the connecting pipe 504.

[0050] During operation, the water pump pumps water into the steam evaporator 502 to form a water-steam mixture, which then enters the steam-water separator 503. The steam-water separator 503 separates the water and steam in the water-steam mixture. The separated water flows back into the steam evaporator 502, while the steam enters the connecting pipe 504. After being heated by the heating resistance wire wound on the surface of the connecting pipe 504, it is injected into the heating chamber for heating.

[0051] Specifically, in this embodiment, the steam-water separator 503 is provided with a water-vapor inlet, a steam outlet, and a water outlet. The water-vapor inlet is connected to the steam outlet of the steam evaporator 502, the steam outlet is connected to the connecting pipe 504, and the water outlet is connected to the water inlet of the steam evaporator 502.

[0052] The water separated by the steam-water separator 503 will flow back to the steam evaporator 502 from the outlet for re-evaporation, and the separated steam will enter the connecting pipe 504 through the steam outlet for heating and be injected into the heating chamber.

[0053] In order to facilitate the filling of water tank 501, a water inlet communicating with water tank 501 is provided at the top of the tank body 10 in this embodiment.

[0054] Meanwhile, to facilitate rapid steam circulation, in this embodiment, the heating unit 50 further includes a fan 505, a steam inlet is provided on the cavity wall of the heating chamber, the fan 505 is installed at the steam inlet, and the outlet of the connecting pipe 504 is opened on the side wall of the fan 505.

[0055] In addition, to accommodate the different heating temperatures required by different foods, this embodiment also includes a temperature regulating unit. The temperature regulating unit includes flow valves installed at the outlet positions of several of the connecting pipes 504, temperature sensors installed in several of the heating chambers, and a control terminal that is communicatively connected to the temperature regulating unit and the heating unit 50.

[0056] During operation, the temperature sensor transmits the temperature inside the heating chamber to the control terminal. At this time, the user can control the steam flow rate into the heating chamber according to the temperature requirements of the food being heated, thereby controlling the temperature inside the heating chamber.

[0057] Meanwhile, in order to avoid the temperature of adjacent heating chambers affecting each other, in this embodiment, the material of tray 30 can be made of heat-insulating material, or a hollow layer can be set inside tray 30.

[0058] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
