Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a fully automatic steamer for processing pasta and other food products. Background Technology

[0002] Steamers for processing pasta and other food products are an indispensable key piece of equipment in the catering industry, especially in Chinese pasta kitchens. They are usually large in size and weight and are used to steam buns, steamed bread, and other foods in batches. In order to facilitate the adjustment of the kitchen layout and daily floor cleaning, these large steamers are usually equipped with wheels at the bottom to move the equipment.

[0003] However, while this wheeled design provides convenience for movement, it also brings new problems. In daily use, such as pushing and pulling heavy steaming trays or opening thick oven doors, the force applied to the steamer can easily cause the entire device to shake or shift. This not only affects the smoothness of operation but also poses a safety hazard in the slippery kitchen environment. In pursuit of stability, some steamers use fixed support legs, but this completely eliminates their mobility, making cleaning and maintenance inconvenient.

[0004] Existing technologies attempt to resolve this contradiction by using casters with brakes, but the locking force of the braking mechanism is limited, and its stability is still insufficient for heavy equipment. Furthermore, the brake pads are prone to wear and failure after prolonged use.

[0005] Therefore, this utility model proposes a fully automatic steamer for processing pasta and other food products to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems of inconvenience in movement and poor stability during operation of the existing fully automatic steamers for processing pastry foods, this utility model aims to provide a fully automatic steamer for processing pastry foods with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a fully automatic steamer for processing pasta and other food products, including a main steamer body and a telescopic mechanism connected to the bottom of the main steamer body.

[0008] The telescopic mechanism includes a base shell, an upper fixed plate, a lower fixed plate that can move up and down, and a scissor mechanism disposed between the upper fixed plate and the lower fixed plate. The bottom of the lower fixed plate is connected to a wheel. The telescopic mechanism also includes a rotating handle for driving the scissor mechanism, a slider threadedly engaged with the rotating handle, and a connecting rod connecting the slider and the scissor mechanism.

[0009] Furthermore, the crossbar of the scissor lift mechanism is provided with a slide rail groove, and pulleys are provided at both ends of the connecting rod. The pulleys are slidably disposed in the slide rail groove. By rotating the handle, the slider is driven to move linearly. The slider pushes the pulley to slide in the slide rail groove via the connecting rod, thereby driving the scissor lift mechanism to move, so that the lower fixed plate connected to the wheel can be raised and lowered. Finally, the wheel is controlled to extend out of the bottom shell to move, or to retract into the bottom shell so that the bottom shell touches the ground to achieve stable fixation.

[0010] Preferably, the fully automatic steamer for processing pasta food further includes a water replenishment mechanism. The water replenishment mechanism includes an outer water tank located above the main body of the steamer, a water pipe connecting the outer water tank to the inside of the main body of the steamer, and a float valve located inside the main body of the steamer for controlling the on / off state of the water pipe. By utilizing the principle of gravitational potential energy difference and buoyancy, the water level inside the steamer is automatically replenished, effectively preventing dry burning.

[0011] Preferably, the float valve includes a float and a lever mechanism linked to the float. This structure is simple and reliable. When the water level inside the main body of the steam oven drops, the float drops accordingly, and the valve is opened by the lever mechanism to replenish water. When the water level rises to a preset height, the float rises, and the valve is closed by the lever mechanism, thus achieving precise automatic water level control.

[0012] Preferably, the telescopic mechanism further includes a cover plate, which is disposed above the bottom shell and completely covers the internal transmission components such as the scissor mechanism, the handle, and the slider. This is to prevent moisture, oil, or dust from entering, thereby protecting the internal components from corrosion and contamination and ensuring the long-term reliability of the telescopic function.

[0013] Preferably, the side wall of the bottom shell is provided with a circular groove for the rotating handle to pass through, and the bottom surface of the bottom shell is provided with a rectangular hole for the wheel to extend or retract. These pre-set openings provide the necessary space for the movement and operation of the relevant components, while ensuring the integrity and sealing of the overall structure.

[0014] This utility model has the following beneficial effects: 1. This utility model solves the contradiction between the inconvenience of moving the steam oven and the poor stability during operation in the prior art by setting up a telescopic mechanism composed of a scissor mechanism, a rotating handle and wheels. It achieves the technical effect of both high mobility and high working stability by extending the wheels to push the oven easily when it needs to be moved and retracting the wheels to make a large area of ​​the bottom shell touch the ground when it is stationary.

[0015] 2. This utility model solves the problem of laborious lifting and lowering operations and potential safety hazards by using a rotating handle with trapezoidal threads to drive the scissor fork mechanism for extension and retraction. It achieves labor-saving operation and utilizes the self-locking property of the trapezoidal threads to prevent the wheels from accidentally retracting or extending under the heavy pressure of the equipment, thereby improving the reliability and safety of the mechanism.

[0016] 3. This utility model solves the problem of traditional steam ovens requiring frequent manual water replenishment and prone to dry burning by setting up a water replenishment mechanism consisting of an external water tank and a float valve. It achieves fully automatic replenishment of steaming water, effectively prevents dry burning of the equipment, reduces labor intensity, and improves the safety and automation of the production process.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 This utility model provides a fully automatic steamer for processing pasta and other food products, which aims to solve the contradiction between the inconvenience of moving steamers and their poor stability during operation in the prior art.

[0021] like Figure 1 As shown, the fully automatic steamer for processing pastry food includes a main steamer body 1 and a telescopic mechanism 2 connected to the bottom of the main steamer body 1. The main steamer body 1 serves as the support platform for the entire device and is used for steaming pastry food. The telescopic mechanism 2 is used to support the main steamer body 1 and enable its movement or fixation.

[0022] Specifically, refer to Figures 1 to 4 The telescopic mechanism 2 includes a bottom shell 201, a cover plate 202, an upper fixed plate 206, a lower fixed plate 207 that can move up and down, and a scissor mechanism 3 located between the upper fixed plate 206 and the lower fixed plate 207. The cover plate 202 is located above the bottom shell 201 and is connected to the bottom of the main steam oven mechanism 1, enclosing the internal components of the telescopic mechanism 2. The upper fixed plate 206 is fixed inside the bottom shell 201, and the lower fixed plate 207 is located directly below the upper fixed plate 206. The action of the scissor mechanism 3 drives the lower fixed plate 207 to move up and down relative to the upper fixed plate 206. The scissor mechanism 3 includes two cross rods 301 that are rotatably connected at the center by a round rod. The upper end of the cross rod 301 is rotatably connected to the upper fixed plate 206, and the lower end is rotatably connected to the lower fixed plate 207, thus forming a stable quadrilateral structure. The cross rod 301 has a slide rail groove 304.

[0023] The telescopic mechanism 2 also includes a rotating handle 203 for driving the scissor lift mechanism 3, a slider 306 threadedly engaged with the rotating handle 203, and a connecting rod 303 with pulleys 305 at both ends. The slider 306 is rotatably connected to the middle of the connecting rod 303, and the pulleys 305 at both ends of the connecting rod 303 are slidably disposed in the slide rail groove 304. The fixing block 302, which is bolted to the upper fixing plate 206, provides radial support and axial limit for the rotating handle 203. The rotating handle 203 passes through the fixed block 302, the slider 306 and another fixed block 302. One end of the rotating handle 203 extends out of the bottom shell 201, and the other end is a cylinder with a trapezoidal thread. The trapezoidal thread is threaded into the threaded hole inside the slider 306. The bottom of the lower fixed plate 207 is connected to a wheel 205. A circular groove 204 is opened on the side wall of the bottom shell 201 for the rotating handle 203 to pass through. A rectangular hole is opened on the bottom surface of the bottom shell 201 for the wheel 205 to extend out.

[0024] As a preferred embodiment, in order to automate the steaming process and prevent dry burning, the steamer also includes a water replenishment mechanism 4, please refer to... Figure 1 The water replenishment mechanism 4 includes an outer water tank 401 located above the main steam oven 1, a water pipe 402 connecting the outer water tank 401 to the inside of the main steam oven 1, and a float valve 403 located inside the main steam oven 1 for controlling the opening and closing of the water pipe 402. The height of the outer water tank 401 is higher than the water level inside the main steam oven 1, and it uses gravitational potential energy to provide power for water replenishment. The float valve 403 includes a float and a lever mechanism that is linked with the float to open or close the valve.

[0025] The working principle of this fully automatic steamer for processing pasta and other food products is as follows: When the steam oven needs to be moved, the operator rotates the handle 203 extending outside the bottom shell 201 in a specific direction. The rotation of the handle 203 drives the slider 306, which is threadedly engaged with it, to move linearly along the axis of the handle 203. The slider 306, through the rotating connecting rod 303, pushes the pulleys 305 at both ends to slide in the slide rail groove 304 of the cross rod 301. This action forces the included angle of the cross rod 301 to change, thereby pulling the lower fixed plate 207 upward. As the lower fixed plate 207 rises, the wheel 205 fixed at its bottom extends out from the rectangular hole on the bottom surface of the bottom shell 201 and contacts the ground, lifting the entire main body mechanism 1 of the steam oven. At this time, the bottom shell 201 is suspended in the air, and the steam oven can be easily pushed.

[0026] Once the steam oven has moved to the designated working position, the operator rotates the handle 203 in the opposite direction, causing the slider 306 to move in the opposite direction. This causes the included angle of the crossbar 301 to change in the opposite direction via the connecting rod 303 and the pulley 305, pushing the lower fixed plate 207 downward. The wheel 205 then retracts into the rectangular hole until the bottom surface of the bottom shell 201 is completely in contact with the ground. At this point, the weight of the steam oven is borne by the entire bottom shell 201. The large contact area provides good stability, and the self-locking characteristic of the trapezoidal thread ensures that the mechanism can be reliably locked in any position, preventing accidental lifting or lowering due to the weight of the equipment.

[0027] During the steaming process, the water inside the main body of the steam oven 1 is consumed due to heating, and the water level drops. The float of the float valve 403 drops accordingly, and the valve connected to the water pipe 402 is opened through the lever mechanism. The water in the outer water tank 401 located at the upper position flows into the main body of the steam oven 1 through the water pipe 402 under the action of gravity. When the water level is replenished to the preset height, the float rises, and the valve is closed again through the lever mechanism to stop water replenishment. This cycle is repeated to achieve fully automatic water level control and effectively prevent dry burning.
