Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pre-prepared food heating devices, and in particular to a pre-prepared food uniform heating device. Background Technology
[0002] Pre-prepared foods are foods that have been pre-processed, treated, or partially cooked and can be eaten after simple heating or combination. Steaming equipment is a common heating device for pre-prepared foods, which uses steam to heat the food.
[0003] A search revealed Chinese Patent Publication No. CN222722401U, which discloses a steaming device for pre-packaged food, relating to the field of food processing technology. The device includes a water tank with multiple electric heating tubes fixedly installed on its inner wall. Multiple evenly spaced insertion holes are formed on the inner wall of the tank, and placement blocks are slidably installed within each insertion hole. Each placement block has a placement groove located within the water tank at its top. This invention has a reasonable structure. Water is heated by the electric heating tubes, and the food is placed in the placement groove. The multiple placement grooves can hold foods with different steaming times. Foods requiring shorter steaming times can be placed on top, allowing them to be removed sequentially from top to bottom. When the steamed food is removed, a sealing mechanism seals the space below the placement blocks, preventing excessive steam leakage and ensuring that the food below continues to steam.
[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned steaming equipment: In the existing technology, easily steamable foods are placed on the upper layer during steaming. When removing the food from the upper layer, a baffle can be pushed into the water tank to prevent excessive steam from overflowing when the food-containing blocks are pulled out, thus avoiding affecting the heating of the food in the lower layer. However, in the use of the existing technology, the width of the baffle needs to be consistent with the width of the water tank. Furthermore, since the baffle protrudes from the side wall of the water tank during the heating process, it greatly increases the volume occupied by the device, which is not conducive to the placement of the device. Based on this, the present invention designs a pre-prepared food uniform heating device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a pre-prepared food uniform heating device to solve the problem mentioned in the background art that the existing devices are too large and inconvenient to place.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a pre-prepared food uniform heating device, comprising a heating box, wherein limit support seats are respectively installed on the inner walls of both sides of the heating box, and a support hole plate is slidably engaged on every two symmetrically installed limit support seats, and a sealing plate is installed on one side wall of the support hole plate;
[0007] A fixed base plate is installed on each pair of symmetrically installed limiting support seats. Each fixed base plate has an air inlet slot. A guide shaft is installed on the bottom outer wall of the limiting support seat via a fixing block. A guide base plate is slidably engaged on the guide shaft. An adjusting base plate is installed on the top outer wall of the guide base plate. Each adjusting base plate has an air inlet slot.
[0008] Each heating chamber is slidably secured with a pull rod, one end of which is connected to the guide base plate.
[0009] As a preferred embodiment, fasteners are installed on both sides of the sealing plate, and the sealing plate is connected to the heating box body through the fasteners.
[0010] As a preferred embodiment, a limiting base plate is installed at one end of the pull rod, a limiting strip is installed on one side wall of the heating box, the limiting base plate and the limiting strip are slidably engaged, a supporting side plate is installed on one side wall of the limiting base plate, and an adjusting bolt is connected to the supporting side plate.
[0011] As a preferred embodiment, a retaining ring for limiting the position of the adjusting base plate is installed on the side wall of the pull rod.
[0012] As a preferred embodiment, a water inlet pipe is installed on the side wall of the heating chamber, and a sealing cap is detachably installed at one end of the water inlet pipe.
[0013] As a preferred embodiment, a handle is installed on one side wall of the sealing plate.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] By pulling the lever at the bottom of the corresponding support plate, the guide plate at one end of the lever can be moved, so that the second air inlet on the adjusting plate is no longer aligned with the first air inlet on the fixed plate. This prevents steam from flowing out through the first air inlet on the fixed plate. Therefore, when the upper support plate is pulled out later, steam will not leak too much from the support plate, thus avoiding affecting the heating of the food in the lower layer. Moreover, the size of the device can be greatly reduced, making it convenient to place. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides, for example Figure 1-7The device for uniformly heating pre-prepared food, as shown, includes a heating chamber 1. A heating coil is installed inside the heating chamber 1. Limiting support seats 2 are installed on the inner walls of both sides of the heating chamber 1. A support plate 3 is slidably engaged with every two symmetrically installed limiting support seats 2. The support plate 3 has multiple through holes. A sealing plate 10 is installed on one side wall of the support plate 3. There are six limiting support seats 2, symmetrically installed in pairs on the inner walls of both sides of the heating chamber 1. A fixed base plate 7 is installed on every two symmetrically installed limiting support seats 2. Air inlets 8 are provided on plate 7. A guide shaft 4 is installed on the bottom outer wall of the limiting support 2 via a fixing block. A guide base plate 5 is slidably engaged on the guide shaft 4. An adjusting base plate 6 is installed on the top outer wall of the guide base plate 5. An air inlet 9 is provided on the adjusting base plate 6. The size and position of the air inlet 9 correspond to the air inlet 8. A pull rod 11 is slidably engaged on the heating box 1. One end of the pull rod 11 is connected to the guide base plate 5. When using this device, the pre-prepared food is placed above the support plate 3, and it can also be used to remove food that is difficult to handle. The food to be heated is placed on the lower support plate 3, and the food that is easy to heat is placed on the upper support plate 3. After placement, the support plate 3 is pushed into the heating chamber 1 along the limiting support seat 2, and the opening on the heating chamber 1 is covered by the sealing plate 10. Then, the heating coil at the bottom of the heating chamber 1 heats the water to generate steam to heat the food. After the food on the upper layer is heated, the pull rod 11 at the bottom of the corresponding support plate 3 is pulled, so that the pull rod 11 can pull the guide plate 5 at one end to move. The base plate 5 can synchronously drive the adjustment base plate 6 to move, so that the second air inlet 9 on the adjustment base plate 6 is no longer aligned with the first air inlet 8 on the fixed base plate 7. This allows the adjustment base plate 6 to cover the first air inlet 8, preventing steam from flowing out through the first air inlet 8 on the fixed base plate 7. Consequently, when the upper support plate 3 is pulled out later, steam will not leak excessively from the support plate 3, thus avoiding affecting the heating of the food in the lower layer. Furthermore, the device is relatively small in size, does not require much space, and is easy to place.
[0026] In this embodiment, as Figure 3 As shown, latches 17 are installed on both sides of the sealing plate 10. The sealing plate 10 is connected to the heating box 1 through the latches 17. The latch 17 is a common part, which is a mechanical device used for connection, fixation or closure, and plays the role of adjustment, fastening or quick opening and closing. The sealing plate 10 is connected to the heating box 1 through the latches 17, so that the support plate 3 can be quickly pulled out when it is necessary to pull out later.
[0027] In this embodiment, as Figure 7As shown, a limiting base plate 12 is installed at one end of the pull rod 11, and a limiting strip 13 is installed on one side wall of the heating box 1. The limiting base plate 12 and the limiting strip 13 are slidably engaged. A supporting side plate 14 is installed on one side wall of the limiting base plate 12, and an adjusting bolt 15 is connected to the supporting side plate 14. By turning the adjusting bolt 15, it is connected to the limiting strip 13, thereby fixing the limiting base plate 12, and thus fixing the pull rod 11.
[0028] In this embodiment, as Figure 5 As shown, a fixing ring 16 is installed on the side wall of the pull rod 11 to limit the position of the adjusting base plate 6. The fixing ring 16 restricts the position of the pull rod 11 so that the position of the adjusting base plate 6 can always be consistent when the pull rod 11 is moved.
[0029] In this embodiment, as Figure 3 As shown, a water inlet pipe 18 is installed on the side wall of the heating chamber 1. A sealing cap 19 is detachably installed at one end of the water inlet pipe 18. Water is poured into the heating chamber 1 through the water inlet pipe 18 by opening the sealing cap 19.
[0030] In this embodiment, as Figure 1 As shown, a handle 20 is installed on one side wall of the sealing plate 10, which facilitates the removal of the support plate 3 from the heating box 1.
[0031] Working principle of this utility model: This utility model is a pre-made food uniform heating device. When using this device, the food is placed above the support plate 3, and then the support plate 3 is pushed into the heating box 1 along the limiting support seat 2. At the same time, the sealing plate 10 can cover the opening on the heating box 1. Then, the water can be heated by the heating ring at the bottom of the heating box 1, and the food is heated by generating steam.
[0032] After the upper layer of food is heated, the pull rod 11 at the bottom of the corresponding support plate 3 is pulled, causing the guide plate 5 at one end to move. This causes the guide plate 5 to move the adjusting plate 6 simultaneously, so that the air inlet 9 on the adjusting plate 6 is no longer aligned with the air inlet 8 on the fixed plate 7. As a result, steam can no longer flow out through the air inlet 8 on the fixed plate 7. Therefore, when the upper support plate 3 is pulled out later, steam will not leak too much from the support plate 3, thus avoiding affecting the heating of the lower layer of food. Moreover, the size of the device can be greatly reduced, making it convenient to place.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
