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.
[0024] Please see Figure 1-5 The present invention provides the following technical solution:
[0025] An easy-to-clean antibacterial groove structure for a tofu box includes an easy-to-clean box body component 1, a cooling component 2 is provided at the bottom of the easy-to-clean box body component 1, and the cooling component 2 includes a mounting frame 201.
[0026] The easy-to-clean box assembly 1 includes a tofu box body 101. Vertical grooves 102 are provided around the inner wall of the tofu box body 101, and horizontal grooves 103 are provided at the bottom of the inner wall of the tofu box body 101. The number of horizontal grooves 103 and vertical grooves 102 is set to multiple, and the multiple horizontal grooves 103 are staggered. The inner walls of the horizontal grooves 103 and vertical grooves 102, as well as the four corners of the inner wall of the tofu box body 101, are all arc-shaped and coated with a nano silver ion antibacterial coating.
[0027] In this embodiment: by setting the easy-to-clean box assembly 1, the tofu box body 101 can be used to hold tofu and provide storage space for tofu. The inner walls of the horizontal groove 103 and the vertical groove 102, as well as the four corners of the inner wall of the tofu box body 101, are all set as arc-shaped. This design can reduce hygiene dead corners, prevent dirt from accumulating in right-angle corners, make cleaning easier, and at the same time make it easier for cleaning tools to reach deeper into all corners inside the tofu box body 101, reducing cleaning dead corners and facilitating comprehensive cleaning of the box. The nano silver ion antibacterial coating can effectively inhibit the growth and reproduction of bacteria, mold and other microorganisms, maintain the hygienic environment inside the tofu box body 101, prevent tofu from being contaminated by bacteria, extend the shelf life of tofu, and ensure the quality and safety of tofu.
[0028] Specifically, such as Figure 4As shown, the mounting frame 201 is fixedly connected to the bottom of the tofu box body 101, and ice blocks are placed inside the mounting frame 201. A pull-out box 202 is movably connected inside the mounting frame 201.
[0029] Specifically, such as Figure 3 , Figure 4 As shown, limit strips 203 are fixedly connected to both sides of the pull-out box 202, and limit grooves 3 that cooperate with the limit strips 203 are provided on both sides of the inner wall of the mounting frame 201.
[0030] Specifically, such as Figure 3 , Figure 4 As shown, a positioning plate 204 is fixedly connected to the outside of the pull-out box 202. A metal block 205 is fixedly connected to the side of the positioning plate 204 near the mounting frame 201. A magnetic block 4 is fixedly connected to the side of the mounting frame 201 near the positioning plate 204, and the magnetic block 4 and the metal block 205 cooperate with each other.
[0031] In this embodiment: Through the above settings, the mounting frame 201 can provide an installation position and support for the pull-out box 202, ensuring the normal operation of the cooling function. The pull-out box 202 serves as a direct container for ice, facilitating the placement or removal of ice from the mounting frame 201, making ice replacement easier and the cooling operation more convenient. During the melting process, the ice absorbs heat from the surrounding environment, lowering the temperature of the mounting frame 201 and its surrounding area. Due to heat transfer, the low temperature around the mounting frame 201 gradually transfers to the bottom of the tofu box body 101, further lowering the internal temperature of the tofu box body 101, creating a low-temperature storage environment for the tofu, and slowing down its spoilage. Simultaneously, the water from the melting ice can be collected in the pull-out box 202, preventing water accumulation from adversely affecting the tofu. Positioning strip 203 can cooperate with limiting groove 3 to guide the pull-out box 202 during insertion or removal from mounting frame 201, ensuring that the pull-out box 202 moves linearly in a fixed direction without shaking or shifting. This ensures that the pull-out box 202 can be accurately installed in mounting frame 201 and maintain a stable position during use. Positioning plate 204 is used to fix metal block 205. When pull-out box 202 is inserted into mounting frame 201, the mutual attraction between metal block 205 and magnetic block 4 can accurately position pull-out box 202 in a suitable position in mounting frame 201, ensuring the fitting accuracy between pull-out box 202 and mounting frame 201. This makes the installation of cooling component 2 more stable, further improving the stability and reliability of cooling component 2 and ensuring the continuous effectiveness of cooling function.
[0032] Specifically, such as Figure 1 As shown, the top of the tofu box body 101 is provided with a box cover 5, and a handle 6 is fixedly connected to the top of the box cover 5.
[0033] Specifically, such as Figure 2 As shown, a sealing ring 7 is glued to the bottom of the lid 5, and a slot 8 for use with the sealing ring 7 is opened on the top of the tofu box body 101.
[0034] In this embodiment: Through the above settings, the lid 5 can prevent external dust and debris from entering the tofu box body 101, avoiding these contaminants from contacting the tofu, thereby ensuring the hygiene and quality of the tofu. It can also block the influence of external temperature to a certain extent. In conjunction with the cooling component 2, it can better maintain the low temperature environment inside the tofu box body 101, extending the shelf life of the tofu. The slot 8 can match the sealing ring 7 at the bottom of the lid 5 to fix the position of the sealing ring 7, so that the sealing ring 7 can accurately fit with the lid 5 and the tofu box body 101, ensuring the sealing effect. This can prevent moisture from entering the tofu box body 101, avoiding the impact of external moisture or liquid splashes on the quality of the tofu. At the same time, it can also maintain the stability of the humidity inside the tofu box body 101, which helps to extend the freshness of the tofu.
[0035] Specifically, such as Figure 5 As shown, an annular groove 9 is provided at the bottom of the inner wall of the tofu box body 101, and a drain hole 10 is provided inside the annular groove 9, and the drain hole 10 is connected to the pull-out box 202.
[0036] In this embodiment: Through the above-mentioned design, the annular groove 9 can effectively collect the water accumulated inside the tofu box body 101, concentrating the water within the annular area to prevent it from flowing freely and wetting the tofu, thus ensuring the quality and taste of the tofu. Simultaneously, its annular structural design helps guide the water towards the drain hole 10, allowing it to smoothly drain from the tofu box body 101, improving drainage efficiency and effectiveness. The drain hole 10 can promptly discharge the water collected in the annular groove 9 into the pull-out box 202, achieving water drainage... Automatic drainage avoids the hassle of frequent manual cleaning of water inside the tofu box body 101, reducing the possibility of bacterial growth. The drain hole 10 is connected to the pull-out box 202, allowing water to flow smoothly into the pull-out box 202 for centralized storage. When the water in the pull-out box 202 reaches a certain amount, the user can easily pull out the pull-out box 202 for cleaning. This design not only facilitates water management but also effectively prevents water from adversely affecting the tofu box body 101 and the tofu. It also helps maintain the normal working environment of the cooling component 2.
[0037] Working principle: First, open the lid 5 and place the tofu into the tofu box body 101. Then, close the lid 5 tightly. The sealing ring 7 will engage with the slot 8, ensuring a tight seal between the lid 5 and the tofu box body 101, creating a sealed environment. Next, place ice cubes into the pull-out box 202 inside the mounting frame 201. Through the interaction of the limiting strip 203 and the limiting groove 3, the pull-out box 202 is inserted into the mounting frame 201. When the pull-out box 202 moves to the appropriate position, the metal block 205 will attract the magnetic block 4, thus fixing the position of the pull-out box 202. As the ice melts, it absorbs heat from the surrounding environment, causing... As the temperature of the mounting frame 201 and its surrounding area decreases, the low temperature around the mounting frame 201 will gradually transfer to the bottom of the tofu box body 101 due to heat transfer, thereby lowering the internal temperature of the tofu box body 101 and creating a low-temperature storage environment for the tofu. During storage, the tofu will seep out water, which will flow into the annular groove 9. The annular groove 9 will collect the water and guide it through the drain hole 10 to the pull-out box 202. When the water in the pull-out box 202 reaches a certain level, the pull-out box 202 can be pulled out for cleaning. After cleaning, the pull-out box 202 can be inserted back into the mounting frame 201.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
