Description

Technical Field

[0001] This utility model belongs to the field of rice steamer technology, specifically relating to a user-friendly kitchen rice steamer. Background Technology

[0002] A rice steamer is a commercial kitchen appliance specifically designed for the rapid cooking of large quantities of rice, noodles, and other ingredients. It is widely used in hotels, schools, factories, military units, and other places that require centralized catering.

[0003] It uses direct steam injection technology to convert water into high-temperature steam (usually 100℃-120℃) through a high-power heating element or gas burner, which quickly penetrates the food to steam rice.

[0004] Rice steamers are typically equipped with multiple rice steaming trays that slide inside the cabinet. During operation, they use either bottom heating or side heating to steam rice on multiple rice steaming trays simultaneously.

[0005] For example, in the prior art, Chinese utility model patent with authorization announcement number CN217792529U discloses "a commercial rice steamer", which includes an inner shell. The inner shell is provided with a rice steaming tray placement plate. Both ends of the rice steaming tray placement plate are installed in U-shaped grooves on a U-shaped card plate. A second connecting plate is provided on one outer wall of the U-shaped card plate. A second through hole is opened on the surface of the second connecting plate. A damping rubber sleeve is provided on the hole wall of the second through hole. A limit post is installed inside the damping rubber sleeve.

[0006] Commercial rice steamers in the prior art, including those mentioned above, can meet general rice steaming needs. However, when the rice steamer is in use, the interior is filled with high-temperature steam (usually around 100°C). The tray will continuously come into contact with the steam and absorb heat. Even after the power is turned off after steaming, the surface temperature of the tray will still be high (possibly above 60°C). Touching it directly will cause a noticeable burning sensation and poses a risk of burns. Using tools to help remove the rice steaming tray is quite troublesome and poses a risk of accidental slippage.

[0007] To address the aforementioned problems, this utility model proposes an easy-to-use kitchen rice steamer. Utility Model Content

[0039] 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.

[0040] Please see Figures 1-5 The present invention provides the following technical solution: a kitchen rice steamer that is easy to use, including a cabinet body 1 and a cabinet door 2 hinged to the front of the cabinet body 1. The bottom of the cabinet body 1 is a hot water tank with an internal electric heating coil 3. It further includes: multiple sets of C-shaped guide rails 5, a rice steaming tray 6, a toggle block 7 and a drive mechanism 8.

[0041] Furthermore, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, two C-shaped guide rails 5 in the same group are symmetrically fixed to the two opposite inner walls of the cabinet 1. The rice steaming tray 6 is slidably installed between the two C-shaped guide rails 5 in the same group. The actuating block 7 is slidably connected to the C-shaped guide rail 5. The driving mechanism 8 is used to drive the actuating block 7 to move along the length direction of the C-shaped guide rail 5. After adopting the above scheme, when using, the food to be heated is placed in the rice steaming tray 6, and then the rice steaming tray 6 is pushed horizontally along the C-shaped guide rails 5 on both sides of the cabinet 1. Multiple sets of C-shaped guide rails 5 are arranged in layers, and multiple rice steaming trays 6 can be placed at the same time.

[0042] When the rice steamer is turned on, the electric heating coil 3 is powered on and heats the water in the hot water tank, generating steam that diffuses upwards and fills the interior of the cabinet 1. The steam comes into direct contact with the surface of the food and transfers heat to the food through thermal convection, causing the food to heat up and cook.

[0043] When it is necessary to remove the rice steaming tray 6, the corresponding drive mechanism 8 is activated. The drive mechanism 8 drives the actuating block 7 to move along the length of the C-shaped guide rail 5. The actuating block 7 pushes the rice steaming tray 6 out of the cabinet 1. The user does not need to reach into the high-temperature area, avoiding burns, and can easily and safely remove the cooked food inside or remove the rice steaming tray 6.

[0044] In the initial state, the toggle block 7 is located at the innermost side of the cabinet 1. As the drive mechanism 8 drives the toggle block 7 to move along the length of the C-shaped guide rail 5, the toggle block 7 gradually moves toward the opening end of the cabinet 1.

[0045] Optionally, by Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the drive mechanism 8 includes: a moving block 81, a fixed plate 82, a threaded screw 83, and a drive motor 84. The moving block 81 is located inside the C-shaped guide rail 5, and a guide sliding hole 51 is provided at the top of the C-shaped guide rail 5. The bottom end of the actuating block 7 passes through the guide sliding hole 51 and is fixedly connected to the moving block 81. Two fixed plates 82 are symmetrically fixed inside the C-shaped guide rail 5. The threaded screw 83 is rotatably installed between the two threaded screws 82, and the threaded screw 83 is connected to the moving block 81 by threaded engagement. The drive motor 84 is fixed to... The back of cabinet 1 is used to drive the screw 83 to rotate. With the above solution, when the steaming is completed and the rice tray 6 needs to be removed, the drive motor 84 is started. The drive motor 84 starts to rotate, driving the screw 83 connected to it to rotate. Since the screw 83 and the moving block 81 are connected by a screw thread, and the moving block 81 is located in the C-shaped guide rail 5, the C-shaped guide rail 5 restricts the rotation of the moving block 81. Therefore, as the screw 83 rotates, the moving block 81 will move linearly along the length of the C-shaped guide rail 5.

[0046] The bottom end of the actuating block 7 passes through the guide sliding hole 51 at the top of the C-shaped guide rail 5 and is fixedly connected to the moving block 81. Therefore, the linear movement of the moving block 81 will drive the actuating block 7 to move synchronously along the length direction of the C-shaped guide rail 5 under the restriction of the guide sliding hole 51. During the movement, the actuating block 7 will push the rice steaming tray 6 to slide outward along the C-shaped guide rail 5 until the rice steaming tray 6 is pushed to a position that is easy for the user to pick up. The user does not need to reach into the high-temperature cabinet 1, thus avoiding the risk of burns.

[0047] Preferably, by Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in this embodiment, the driving mechanism 8 further includes: guide rods 85. Two guide rods 85 are symmetrically fixed between two fixed plates 82 and pass through the moving block 81. With the above solution, during use, when the moving block 81 moves along the threaded screw 83, the guide rods 85 can prevent the moving block 81 from shaking, tilting or deviating, so that the moving block 81 can move more smoothly and accurately along the length direction of the C-shaped guide rail 5. The actuating block 7 connected to the moving block 81 also moves smoothly along the guide sliding hole 51, and finally pushes the rice steaming tray 6 to slide outward along the C-shaped guide rail 5 to a position that is easy to pick up, ensuring the safety and smoothness of the tray picking operation.

[0048] Preferably, by Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the outer wall of the actuating block 7 is attached to the inner wall of the guide sliding hole 51, and the top surface of the moving block 81 is attached to the inner wall of the C-shaped guide rail 5. After adopting the above scheme, when in use, the outer wall of the actuating block 7 is attached to the inner wall of the guide sliding hole 51 to form a high-precision sliding pair, which restricts the radial shaking of the actuating block 7 and ensures that it can only move linearly along the length direction of the C-shaped guide rail 5.

[0049] The top surface of the movable block 81 is in contact with the inner wall of the C-shaped guide rail 5 to form a top surface limit, preventing the movable block 81 from jumping up and down due to axial force when driven by the threaded screw 83.

[0050] Preferably, by Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown in this embodiment, the drive mechanism 8 further includes: a sprocket 86 and a chain 87. Two actuating blocks 7, moving blocks 81 and threaded screws 83 are symmetrically distributed, and sprockets 86 are fixed on both threaded screws 83. The two sprockets 86 are driven by the chain 87. With the above scheme, when in use, the synchronous rotation of the two threaded screws 83 will cause the moving blocks 81 on both sides to move linearly along the guide rod 85 and the threaded screws 83. Due to the transmission of the sprockets 86 and the chain 87, the movement of the moving blocks 81 on both sides is synchronous. The actuating block 7 connected to the moving block 81 will also move synchronously along the guide slide hole 51, pushing the rice steaming tray 6 outward along the C-shaped guide rail 5 from both sides, so that the rice steaming tray 6 can be pushed smoothly and easily to a position that is easy for the user to pick up.

[0051] The sprocket 86 and chain 87 drive have high reliability and stability, can adapt to high temperature and humidity conditions in the kitchen environment, reduce the possibility of failure, and extend the service life of the drive mechanism 8.

[0052] Preferably, by Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown in this embodiment, the top of the C-shaped guide rail 5 has an inverted L-shaped bend 52 that bends outward. The actuating block 7 is located between the inverted L-shaped bend 52 and the C-shaped guide rail 5, and the end of the rice steaming tray 6 is embedded in the inner space between the inverted L-shaped bend 52 and the C-shaped guide rail 5. With the above solution, when in use, the main body of the C-shaped guide rail 5 is used to support the rice steaming tray 6, and the inverted L-shaped bend 52 is used to restrict the rice steaming tray 6 from the top to prevent the rice steaming tray 6 from jumping out of the C-shaped guide rail 5.

[0053] During the pushing process, the inverted L-shaped bend 52 and the C-shaped guide rail 5 constrain the end of the rice steaming tray 6 to ensure that the rice steaming tray 6 remains stable when it is pushed out, and there will be no tilting or excessive shaking.

[0054] Alternatively, in this embodiment, a permanent magnet is fixed at one end of the C-shaped guide rail 5 and the outer wall of the actuating block 7 to attract each other. With the above solution, when the rice steaming tray 6 is completely pushed into the cabinet 1 along the C-shaped guide rail 5, the permanent magnets attract each other, which can realize non-contact precise positioning, automatic adsorption and fixation and anti-misoperation protection, significantly improving the reliability and safety of operation.

[0055] Preferably, by Figures 1-3 As shown, this embodiment further includes: a flow guide sleeve 4, which is fixed inside the cabinet 1 and connected to the hot water tank at the bottom of the cabinet 1. The flow guide sleeve 4 has multiple air outlets 41 that are evenly distributed in the vertical direction. With the above solution, when in use, the electric heating coil 3 is energized and heats the water in the hot water tank, generating steam that diffuses upward. Some of the steam directly enters the cabinet 1, and some enters the flow guide sleeve 4. When the steam enters the flow guide sleeve 4, it will be discharged through the air outlets 41 that are evenly distributed in the vertical direction. This design allows the steam to be released evenly at different heights inside the cabinet 1.

[0056] In traditional rice steamers, steam may stratify, resulting in uneven heating of food on the upper and lower layers. Multiple evenly spaced steam vents 41 can effectively prevent this from happening. Steam diffuses evenly into the cabinet 1 from each steam vent 41, making the temperature in the entire steaming space more uniform. Food placed on the upper, middle, or lower steaming trays 6 can receive relatively consistent heat, thus ensuring that all food can be steamed evenly at the same time.

[0057] It should be noted that the drive motor 84 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated further in this article.

[0058] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0059] Components not described in detail in this article are existing technologies.

[0060] The working principle and usage process of this utility model: When using the rice steamer of this utility model, place the food to be heated in the rice steaming tray 6, and then push the rice steaming tray 6 horizontally along the C-shaped guide rails 5 on both sides of the cabinet body 1. Multiple sets of C-shaped guide rails 5 are arranged in layers, and multiple rice steaming trays 6 can be placed at the same time.

[0061] After the rice steamer is turned on, the electric heating coil 3 is powered on and heats the water in the hot water tank, generating steam that diffuses upward. Some of the steam enters the cabinet 1 directly, and some enters the guide jacket 4. When the steam enters the guide jacket 4, it will be discharged through the air outlets 41 that are evenly distributed in the vertical direction. This design allows the steam to be released evenly at different heights inside the cabinet 1, filling the interior of the cabinet 1. The steam comes into direct contact with the surface of the food and transfers heat to the food through thermal convection, causing the food to heat up and cook.

[0062] When it is necessary to remove the rice steaming tray 6, the corresponding drive mechanism 8 is activated. The drive mechanism 8 drives the actuating block 7 to move along the length of the C-shaped guide rail 5. The actuating block 7 pushes the rice steaming tray 6 out of the cabinet 1. The user does not need to reach into the high-temperature area, avoiding burns, and can easily and safely remove the cooked food inside or remove the rice steaming tray 6.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
