Description
Technical Field
[0001] This utility model relates to the field of kitchen equipment, and in particular to a door sealing structure for a rice steamer. Background Technology
[0002] With the continuous development of the catering industry and the increasing demand for group dining, steam rice cookers, as an important rice cooking equipment, have been widely used in various canteens, restaurants, hotels, and other places. Their basic working principle is to generate high-temperature steam, which evenly heats and cooks the rice in the steaming trays inside the cooker, thus meeting the dining needs of a large number of people. The airtightness of the cooker door is one of the key factors in ensuring the normal operation of the equipment and improving steaming efficiency. Good sealing can prevent steam leakage, reduce heat loss, and ensure the uniformity and safety of the steaming process.
[0003] However, most common rice steamer door sealing structures currently use adhesive bonding. This adhesive bonding sealing structure has several drawbacks. First, adhesive bonding sealing strips are prone to aging and deformation due to the erosion of high-temperature steam over long-term use, leading to a decline in sealing performance. Second, once the adhesive bonding sealing strip is damaged, the replacement process is cumbersome, requiring complete cleaning of the old sealing strip before re-attaching. This is not only time-consuming and labor-intensive but may also result in the sealing strip not adhering firmly, further affecting the sealing effect. In addition, adhesive bonding sealing strips are prone to loosening due to frequent opening and closing of the cabinet door during use, which also affects the sealing performance, allowing steam to leak easily. This not only wastes energy but may also affect the cooking effect and efficiency. Therefore, the traditional adhesive bonding sealing structure can no longer meet the high sealing performance requirements of modern steam rice steamers, and a more reliable, durable, and easily replaceable sealing structure is urgently needed to solve the above problems.

[0027] refer to Figures 1-6 This embodiment provides a sealing structure for the cabinet door 2 of a rice steamer 1, including a transparent cabinet door 2 and an elastic sealing strip 3 with a U-shaped cross-section (such as...). Figure 4The cabinet door 2 is movably connected to the cabinet body of the rice steamer 1; a U-shaped groove 21 is provided on the inner side of the cabinet door 2 near the edge of the cabinet door 2 (e.g., Figure 3 The elastic sealing strip 3 is engaged with the U-shaped groove 21 through its U-shaped structure 31, and the engagement between the U-shaped structure 31 and the U-shaped groove 21 is an interference fit; the elastic sealing strip 3 is distributed on the four sides of the inner side of the cabinet door 2; when the cabinet door 2 is closed, the elastic sealing strip 3 is tightly fitted with the opening edge of the cabinet body.
[0028] In this embodiment, a U-shaped groove 21 is machined on the inner side of the cabinet door 2 near the edge. Its size and shape match the U-shaped structure 31 of the elastic sealing strip 3. The U-shaped structure 31 of the elastic sealing strip 3 is aligned with the U-shaped groove 21 on the inner side of the cabinet door 2, and the sealing strip is pressed into the groove, creating an interference fit between the sealing strip and the groove (e.g., ...). Figure 6 This ensures a secure connection between the sealing strip and cabinet door 2. During operation, attention must be paid to the installation direction and position of the sealing strip to ensure it is evenly distributed on the four sides of the inside of cabinet door 2, and that it fits tightly against the edge of the cabinet opening when cabinet door 2 is closed.
[0029] A further optimized design of the U-shaped groove 21 is that U-shaped grooves 21 are provided on the four sides of the inner side of the cabinet door 2; the U-shaped grooves 21 are laid along the side length of the four sides to form a continuous U-shaped groove 21, so that the elastic sealing strip 3 can be evenly distributed and installed along the entire edge of the cabinet door 2 to form a complete sealing ring, which further enhances the sealing effect between the cabinet door 2 and the cabinet body, avoids the problem of steam leakage caused by the absence or improper installation of the local sealing strip, and ensures the sealing integrity of the entire rice steaming process.
[0030] Align the U-shaped structures 31 of the elastic sealing strip 3 sequentially and insert them into the continuous U-shaped grooves 21, ensuring that the sealing strip fits tightly against the grooves along the edge of the cabinet door 2, thus completing the installation of the sealing strip on the cabinet door 2. The continuous U-shaped grooves 21 provide a uniform installation reference for the elastic sealing strip 3, which helps to ensure the flatness and consistency of the sealing strip installation, reduces local sealing defects caused by uneven installation of the sealing strip, and improves the overall performance and reliability of the sealing structure.
[0031] The sealing strip is a single piece, and its length is adapted to the perimeter of the cabinet door 2. For example... Figure 5 The U-shaped structure 31 of the sealing strip is snapped into the continuous U-shaped groove 21 on the inner side of the cabinet door 2. Starting from one corner of the cabinet door 2, the sealing strip is snapped into the groove one by one until the sealing strip surrounds the entire edge of the cabinet door 2 and the ends are connected to complete the installation of a whole sealing strip.
[0032] Using a single sealing strip of the same length as the perimeter of the cabinet door 2 ensures that the sealing strip is evenly distributed along the edge of the cabinet door 2, avoiding uneven sealing that may be caused by splicing multiple sealing strips. This makes the sealing effect between the cabinet door 2 and the cabinet body more uniform and consistent, ensuring that steam is evenly distributed inside the rice steamer 1, and improving the uniformity and quality of rice steaming.
[0033] The elastic sealing strip 3 is a rubber sealing strip, a silicone sealing strip, or a polyurethane sealing strip. Materials such as rubber, silicone, and polyurethane all possess excellent elasticity, flexibility, and high-temperature resistance, enabling them to adapt to the high-temperature and high-humidity working environment inside the rice steamer 1. This ensures that the sealing strip is not prone to aging or deformation during long-term use, thereby maintaining stable sealing performance, effectively preventing steam leakage, and improving rice steaming efficiency and safety.
[0034] The elastic sealing strip 3 is a snap-fit sealing strip. Snap-fit sealing strips are a common type of sealing strip that is fixed to the installation position via a slot or snap-fit structure. In this embodiment, the snap-fit sealing strip is installed using a slot-type installation method. The sealing strip is fixed to the installation position via a slot structure, and installation simply requires inserting the sealing strip into the corresponding slot.
[0035] like Figure 2 The transparent portion of the cabinet door 2 is made of tempered glass. Using tempered glass for the transparent portion of the cabinet door 2 provides excellent transparency and high strength, allowing users to clearly observe the cooking process of the rice inside the rice steamer 1 without opening the door 2. This facilitates timely monitoring of the cooking progress, preventing overcooking or undercooking, and improving the convenience and accuracy of rice steaming.
[0036] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
