Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a multi-layer steaming and cooking device for food. Background Technology

[0002] In the food processing industry, steaming is a very common and important processing method, widely used in the processing of various grains, beans, meats and vegetables. In traditional home or small-scale food processing scenarios, steaming is usually done using a single-layer steamer or an ordinary steamer.

[0003] In traditional single-layer steaming methods, the number of steaming layers is limited, and the amount of food that can be processed at one time is relatively small. For large-scale food production enterprises, in order to meet the market demand for a large number of finished products, it is necessary to equip multiple single-layer steaming devices to operate simultaneously. This not only occupies a lot of production space, but also increases the costs of equipment purchase, maintenance and energy consumption.

[0004] Existing multi-layer steaming equipment (such as traditional multi-layer steamers, steam ovens, and steam-grill combos) relies on steam flowing from bottom to top, resulting in uneven heating of food in the upper and lower layers. For example, food in the upper layer may become soft due to condensation dripping from the steam, while food in the lower layer may not be fully cooked due to insufficient steam. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer food cooking device that solves the problem of uneven heating in traditional cooking equipment.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A multi-layer steaming and cooking device for food includes a heating box, a steaming box on the top of the heating box, a rectangular array of exhaust ports on the top of the heating box, multiple steaming trays equidistantly slidably inserted on one side of the steaming box, slide rails equidistantly and symmetrically fixed inside the steaming box, the bottom sides of the steaming trays being slidably connected to corresponding slide rails, short rods equidistantly fixed on one side of the steaming box, a stop block rotatably connected to one end of the short rods, the stop blocks being respectively set on one side of the corresponding steaming trays, a retaining ring on the side of the stop block near the steaming box, a movable ring slidably connected to the outside of the short rods, the side opposite to the retaining ring and the movable ring being arranged in a ring-shaped wave shape, and the retaining ring and the corresponding movable ring being mutually fitted, a spring being sleeved on the outside of the short rods, and the movable ring being elastically connected to the steaming box through the spring.

[0007] Preferably, a water inlet is provided on the top edge of the heating box, and a sealing cap is provided on the water inlet to seal the water inlet after water filling is completed, so as to prevent steam leakage and external impurities from entering the heating box. A drain pipe is provided at the bottom of the heating box, and a hand valve is installed on the drain pipe. The opening and closing of the drain pipe can be controlled by operating the hand valve so as to drain the water remaining in the heating box when needed.

[0008] Preferably, a transparent observation window is provided on the side of the steamer away from the short rod. Through this transparent observation window, the steaming status of the food on the steaming tray inside the steamer can be directly observed without opening the steamer door, thereby reducing steam loss and maintaining a stable steaming environment inside the steamer.

[0009] Preferably, a handle is provided on one side of the steaming tray to facilitate the operator to pull the steaming tray out. Several small holes are evenly spaced on the bottom of the steaming tray, so that steam can penetrate the food placed on the steaming tray evenly through the small holes, ensuring that all parts of the food are heated evenly.

[0010] Preferably, there are ear boxes on both sides of the steamer, and the inner wall of the ear box is connected to the inside of the steamer at the corresponding point of the steaming tray, so that steam can circulate freely in the ear box and inside the steamer. While increasing the steam capacity, it can also play an auxiliary heating role for food placed at the edge of the steaming tray.

[0011] Preferably, the top of the steamer has several vent holes at equal intervals to ensure that excess steam generated during food cooking is discharged in a timely manner, thus avoiding excessive pressure inside the steamer that could affect the normal operation of the device and the quality of food cooking.

[0012] Preferably, the two corners of the steaming tray along the pushing direction are rounded, so that the steaming tray can slide smoothly along the slide rail during the process of pushing the steaming box, reducing friction and collision with the inner wall of the steaming box or other parts, reducing the difficulty of operation and the wear of the steaming tray.

[0013] Compared with the prior art, the advantages of this utility model are as follows: This invention utilizes symmetrically arranged sliding rails within the steamer, allowing for multi-layer food placement. By leveraging the vertical space of the steamer, a large quantity of food can be steamed simultaneously within a limited area, improving steaming efficiency. The side panels of the steamer are connected to the interior, and equidistant vents are located on the top. The side panels increase the steam capacity, enabling more thorough steam diffusion and circulation, while the vents expel excess steam. This synergistic effect ensures uniform steam distribution throughout the steamer, preventing uneven cooking and ensuring that all food on the steamers is heated evenly, achieving optimal steaming results and improving food quality stability.

[0014] This invention utilizes a short rod, a stop block, a retaining ring, a movable ring, and a spring on one side of the steamer to form a reliable locking mechanism. The stop block effectively blocks the steaming tray, preventing it from being pulled out unexpectedly and ensuring safety during the steaming process. When it is necessary to pull out the steaming tray, simply rotate the stop block to separate it from the tray. During rotation, the wave-shaped structure of the retaining ring and the movable ring, in conjunction with the spring, ensures both the flexibility of the stop block's rotation and prevents it from shifting without external force, thus ensuring the stability and reliability of the locking mechanism.

[0021] 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.

[0022] Please see Figures 1 to 5 This embodiment provides a multi-layer steaming and cooking device for food, including a heating box 1, a steaming box 2 on the top of the heating box 1, a plurality of exhaust ports 3 in a rectangular array on the top of the heating box 1, a plurality of steaming trays 4 equidistantly slidably inserted on one side of the steaming box 2, slide rails 5 equidistantly and symmetrically fixed inside the steaming box 2, the bottom sides of the steaming trays 4 respectively slidably connected to the corresponding slide rails 5, a short rod 6 equidistantly fixed on one side of the steaming box 2, a stop block 7 rotatably connected to one end of the short rod 6, the stop blocks 7 are respectively set on one side of the corresponding steaming trays 4, a retaining ring 8 is provided on the side of the stop block 7 near the steaming box 2, a movable ring 9 is slidably connected to the outside of the short rod 6, the side opposite to the retaining ring 8 and the movable ring 9 are both arranged in a ring-shaped wave shape, and the retaining ring 8 and the corresponding movable ring 9 are closely fitted to each other, a spring 10 is sleeved on the outside of the short rod 6, and the movable ring 9 is elastically connected to the steaming box 2 through the spring 10.

[0023] When this multi-layer food steaming and cooking device is working, the heating tube inside the heating chamber 1 heats the water to generate steam. The steam enters the steaming chamber 2 through the exhaust port 3 and steams the food placed on the steaming tray 4. The steaming tray 4 is installed in the steaming chamber 2 in a pull-out manner through a sliding connection with the slide rail 5. It can be pulled out from one side of the steaming chamber 2 for easy food handling. The stop block 7 is used to restrict the pulling out of the steaming tray 4. Under normal circumstances, the stop block 7 blocks the steaming tray 4, preventing it from being pulled out. When it is necessary to pull out the steaming tray 4, the stop block 7 is rotated to offset its position from the steaming tray 4. During the rotation of the stop block 7, the retaining ring 8 will squeeze the movable ring 9, causing the spring 10 to contract. When the wavy arc on the movable ring 9 and the retaining ring 8 are aligned, the spring 10 rebounds, making the movable ring 9 and the retaining ring 8 fit tightly together. This structural feature prevents the stop block 7 from rotating or shifting when there is no external force, ensuring the stability and reliability of the device.

[0024] A water inlet 11 is provided on the top edge of the heating box 1, and a sealing cap 12 is provided on the water inlet 11. A drain pipe 13 is provided at the bottom of the heating box 1, and a hand valve 14 is installed on the drain pipe 13. When water needs to be added to the heating box 1, the sealing cap 12 is opened and water is injected into the heating box 1 through the water inlet 11. After the water is added, the sealing cap 12 is closed to ensure that a relatively sealed space is formed inside the heating box 1, which is conducive to the generation of steam and the cooking process. After the cooking process is completed or when the heating box 1 needs to be cleaned and maintained, the hand valve 14 is operated to open the drain pipe 13, and the water remaining in the heating box 1 is discharged through the drain pipe 13. After the operation is completed, the hand valve 14 is operated again to close the drain pipe 13.

[0025] A transparent observation window 15 is provided on the side of the steamer 2 away from the short rod 6. During the food steaming process, the operator can observe the color change, expansion degree and other steaming status information of the food on the steaming tray 4 in the steamer 2 in real time through the transparent observation window 15. Based on the observation results, the operator can adjust the steaming time or temperature and other parameters in a timely manner, avoiding the loss of a large amount of steam caused by frequent opening of the door, effectively maintaining the stability of temperature and humidity in the steamer 2, and ensuring the quality and efficiency of food steaming.

[0026] A handle 16 is provided on one side of the steaming tray 4, and several small holes 17 are evenly spaced on the bottom of the steaming tray 4. When operating this multi-layer food steaming and cooking device, the operator can hold the handle 16 on one side of the steaming tray 4 to pull the steaming tray 4 stably and effortlessly, so as to place and remove the food. During the steaming process, the steam generated by the heating box 1 enters the steaming box 2, and the steam can penetrate the food placed on the steaming tray 4 evenly through these small holes 17. The setting of the small holes 17 avoids the problem of steam accumulating in some parts of the food or poor circulation, so that the upper and lower surfaces and all parts of the food can be fully contacted by the steam, thereby achieving uniform heating and ensuring consistent taste and quality of the food after steaming and cooking.

[0027] The steamer 2 is equipped with ear boxes 18 on both sides. The inner walls of the ear boxes 18 are connected to the interior of the steamer 2 at the corresponding points of the steaming tray 4. During the operation of this multi-layer food steaming and cooking device, the steam generated by the heating box 1 enters the steamer 2 and naturally flows from the interior of the steamer 2 to the ear boxes 18. The presence of the ear boxes 18 increases the overall steam capacity, allowing the steam to diffuse and circulate more fully. For food placed at the edge of the steaming tray 4, which may have been insufficiently heated due to its distance from the main steam generation area, the steam in the ear boxes 18 can now provide auxiliary heating, ensuring the uniformity of steam distribution in all parts of the steamer 2. This allows all food on the steaming tray 4 to achieve good steaming results, improving the quality and consistency of food steaming and cooking.

[0028] The top of the steamer 2 is provided with several vent holes 19 at equal intervals. During the operation of the multi-layer food steaming and cooking device, the steam generated by the heating box 1 continuously enters the steamer 2 to steam the food. As the amount of steam gradually increases, the pressure inside the steamer 2 will increase accordingly. At this time, the vent holes 19 at equal intervals on the top of the steamer 2 begin to play their role. When the pressure inside the steamer 2 reaches a certain level, the excess steam will be discharged in an orderly manner through the vent holes 19, thereby effectively preventing the pressure inside the steamer 2 from being too high. This avoids damage to the device structure due to excessive pressure, or affecting the normal steaming process of the food, such as causing the food surface to crack or uneven steaming. At the same time, the aperture of the vent holes 19 can also control the steam discharge speed, preventing a large amount of heat loss inside the steamer 2 due to excessive discharge. This maintains a relatively stable temperature and humidity environment inside the steamer 2, ensuring that the food can be steamed and cooked under suitable conditions, thus guaranteeing the taste and quality of the food.

[0029] The two corners of the steaming tray 4 along the pushing direction are rounded. During the operation of pushing the steaming tray 4 into the steaming oven 2 to place food, the rounded corners of the steaming tray 4 can guide the tray 4 as it slides along the slide rail 5, so that the steaming tray 4 can enter the steaming oven 2 more smoothly. This avoids the jamming and collision problems that may be caused by the right angle design with the inner wall or other parts of the steaming oven 2, reduces the difficulty for the operator to push the steaming tray 4 in, and also reduces the wear and tear of the steaming tray 4 caused by friction and collision, thus extending the service life of the steaming tray 4.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
