Description

Technical Field

[0001] This invention relates to the field of steam oven technology, and more specifically, to a dual-energy, movable, double-layer stainless steel steam oven specifically for tofu pudding. Background Technology

[0002] This dual-energy portable double-layer stainless steel steamer for tofu pudding is made entirely of food-grade stainless steel and features a dual-energy switching system for electricity and gas. It is suitable for both fixed store operations and mobile stalls. The bottom is equipped with casters for easy relocation and transport. The double-layer independent steaming chambers ensure even steam circulation and stable temperature control, allowing for the simultaneous steaming of multiple portions of tofu pudding. The thickened insulation layer of the chamber locks in heat and saves energy. The sealed, drip-proof design ensures the tofu pudding has a smooth texture and does not become watery. It also features water shortage protection and constant temperature insulation functions. It is specifically designed for breakfast shops and mobile food stalls to steam and keep tofu pudding warm in batches. It is easy to clean and maintain, and is highly practical and adaptable.

[0003] When existing steam ovens are in use, their inner walls are filled with a large amount of high-temperature water vapor. Since it is not convenient to deal with the overflowing high-temperature water vapor when the lid of the steam oven is opened, the operator is easily burned by the overflowing hot steam, which poses a certain safety hazard.

[0004] Therefore, we have made improvements and proposed a dual-energy, portable, double-layer stainless steel steamer specifically for tofu pudding. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the purpose of the present invention is to provide a dual-energy movable double-layer stainless steel steamer for tofu pudding.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: A dual-energy, portable, double-layer stainless steel steamer for tofu pudding includes a main body, a lid at the opening of the main body, a water-collecting component slidably fitted on the inner wall of the bottom of the lid, a rotating end fixedly connected to one end of the lid, a transmission component rotatably connected to the inner wall of the main body, an air-inflating base below the transmission component, and an air-blowing anti-scalding component slidably fitted on the lower inner wall of the opening of the main body.

[0021] This steamer is made entirely of double-layered 304 stainless steel, making it resistant to high temperatures, corrosion, and rust, and suitable for long-term constant-temperature steaming of tofu pudding. The bottom of the equipment is equipped with casters for easy mobility, facilitating flexible placement and transport in the kitchen. The equipment supports dual-energy independent heating modes: it can be connected to mains power for electric heating or to liquefied petroleum gas for gas heating, adapting to different usage scenarios in kitchens with or without mains power, making it highly versatile. A precise thermometer is embedded in the side wall of the steamer to monitor the steaming temperature in real time, allowing staff to easily control the steaming time and temperature of the tofu pudding, preventing undercooking, excessive honeycomb texture, and a hard consistency.

[0022] Spring 702 drives the sliding frame 701 to move outward automatically.

[0023] Furthermore, by setting up the air-blowing anti-scalding component 7, when the lid 2 is opened, the rotating end 4 connected to the lid 2 can drive the piston plate 603 inside the air-filling seat 6 to move back and forth quickly through the transmission component 5, thereby causing the air-blowing anti-scalding component 7 to spray high-pressure air upwards and blow the overflowing high-temperature water vapor upwards, greatly reducing the safety risk of operators being burned by direct contact with high-temperature steam and improving the safety of the steamer.

[0024] In the preferred embodiment of this technical solution, please refer to Figure 3 As shown, a storage groove 201 is provided at the bottom of the box cover 2, and a drainage groove 202 is provided through the bottom of the storage groove 201.

[0027] Furthermore, when the lid 2 is closed and under pressure, the end face of the steamer body 1 presses against the water receiving trough 301, compressing the second spring 302, causing the water receiving trough 301 to completely retract into the storage trough 201; when the lid 2 is flipped upwards to open, after the pressure disappears, the second spring 302 elastically rebounds, automatically pushing the water receiving trough 301 to slide outwards, realizing automatic water collection when the lid is opened. When the water guide hole 303 is aligned with the drain trough 202, the water in the water receiving trough 301 is automatically discharged.

[0028] In the preferred embodiment of this technical solution, please refer to Figure 4 As shown, one end of the rotating end 4 is rotatably connected to the outer wall of the steam oven body 1 at both ends.

[0029] Furthermore, the drive wheel 402 can increase the rotational speed of the transmission wheel 502.

[0030] In the preferred embodiment of this technical solution, please refer to Figure 4 As shown, the transmission assembly 5 includes a rotating shaft 501, which is rotatably connected to the inner wall of the steamer body 1. A transmission wheel 502 is fixedly connected to the outer wall of one end of the rotating shaft 501. The transmission wheel 502 is meshed with the drive wheel 402 for transmission. A transmission wheel 503 is fixedly connected to the other end of the rotating shaft 501.

[0031] Furthermore, the second transmission wheel 503 can increase the rotational speed of the driven wheel 504.

[0032] In the preferred embodiment of this technical solution, please refer to Figure 4 As shown, a driven wheel 504 is meshed and driven below the transmission wheel 503. The driven wheel 504 is rotatably connected to the inner wall of the steamer body 1 via a pin. An L-shaped rod 505 is fixedly connected to one end of the driven wheel 504.

[0033] Furthermore, the L-shaped rod 505 drives the piston rod 601 to reciprocate.

[0034] In the preferred embodiment of this technical solution, please refer to Figure 5As shown, a piston rod 601 is slidably fitted through the top of the inflatable base 6, and a movable frame 602 is fixedly connected to the top of the piston rod 601. The inner wall of the movable frame 602 is slidably fitted with the outer end of the L-shaped rod 505.

[0035] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, a piston plate 603 is fixedly connected to one end of the piston rod 601 located inside the inflation seat 6, and the outer wall of the piston plate 603 is slidably fitted with the inner wall of the inflation seat 6.

[0036] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, an air inlet pipe 604 is fixedly connected to one side of the top of the air inlet seat 6, and the other end of the air inlet pipe 604 is fixedly connected to the inner wall of the steam oven body 1. A filter element is installed on the inner wall of the air inlet pipe 604.

[0037] Furthermore, a one-way valve is installed inside the intake pipe 604.

[0038] In the preferred embodiment of this technical solution, please refer to Figure 6 As shown, an air guide pipe 704 is slidably fitted on the inner wall of the outer end of the jet pipe 703, and the other end of the air guide pipe 704 is fixedly connected to the inner wall of the inflation seat 6.

[0039] Furthermore, a one-way valve is installed inside the air duct 704.

[0040] Working Principle: This steamer uses a double-layer stainless steel cavity, providing excellent heat insulation and reducing heat loss. Operators can freely choose the heating mode based on the available power supply. Electric heating mode is available when electricity is available, while liquefied petroleum gas (LPG) heating mode is available when no mains power is available, allowing for flexible dual-energy adaptation. The equipment is equipped with casters at the bottom for easy movement and placement. A side-wall thermometer displays the steaming temperature in real time, ensuring precise control of the tofu pudding steaming process. When the lid 2 is closed, the bottom of the lid 2 presses against the sliding frame 701, compressing the first spring 702, causing the anti-scalding air blowing component 7 to retract and hide. Simultaneously, the end face of the steamer body 1 presses against the water receiving tank 301, compressing the second spring 302, completely retracting the water receiving component 3 into the storage slot 201.

[0041] After steaming is completed, the lid 2 is flipped open. The lid 2 drives the end rotating end 4 to rotate synchronously. The rotating end 4 drives the internal drive wheel 402 to rotate through the universal joint 401. The drive wheel 402 engages and drives the transmission wheel 502 to rotate rapidly. The power is transmitted synchronously to the transmission wheel 503 through the rotating shaft 501. The transmission wheel 503 engages again and drives the driven wheel 504 to further increase the speed.

[0042] Then, driven wheel 504 drives L-shaped rod 505 to perform eccentric circular motion, continuously pushing and pulling piston rod 601 and piston plate 603 up and down through movable frame 602; when piston plate 603 moves upward, air seat 6 generates negative pressure, and outside air is drawn into the cavity through air inlet pipe 604, filter element and air inlet one-way valve; when piston plate 603 moves downward, compressed air in the cavity forms high-pressure airflow, airflow pushes open air outlet one-way valve inside air guide pipe 704 and delivers it to jet pipe 703; at the same time, the squeezing pressure of lid 2 disappears when it is opened, spring 702 rebounds and pushes sliding frame 701 outward, jet pipe 703 moves outward in sync with the steamer opening, spraying high-pressure air curtain upward, guiding all the high-temperature steam rushing forward upward, avoiding steam directly facing the operator, realizing automatic anti-scalding blowing when opening the lid.

[0043] After the lid 2 is opened, the spring 2 302 rebounds and pushes the water receiving trough 301 to slide out automatically, catching all the high-temperature condensed water droplets that slide down the inner wall of the lid 2; after the water receiving trough 301 is reset, the bottom water guide hole 303 automatically aligns with the bottom drain groove 202 of the lid 2, and the collected hot water is automatically discharged downward by gravity, without the need for manual pouring, thus avoiding hot water dripping and scalding hands.
