Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and more specifically, to a handle-type water-adding structure and a cooking utensil. Background Technology

[0002] With the rapid development of modern kitchen appliance technology, the functional design of cooking appliances (such as rice cookers, electric pressure cookers, steamers, etc.) increasingly emphasizes convenience and user experience. During the cooking process, some appliances need to replenish water in their internal liquid storage chambers to maintain cooking humidity, generate steam, or achieve specific functions (such as steam heating).

[0003] Traditional cooking appliances typically have a liquid reservoir fixedly connected to the main structure, with a tray on top. This tray often needs to be moved, for example, to empty the backflow water or to add water to the reservoir. For larger trays or cooking containers, frequent moving or disassembling to add water is not only laborious but may also pose safety hazards due to high-temperature operation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a handle-type water-adding structure and cooking utensil, which solves the problems of large trays being inconvenient to move and difficult to add water to the liquid storage chamber.

[0005] To achieve the above objectives, in a first aspect, this application provides a handle-filled water structure for use in cooking appliances, including a liquid storage chamber, a tray disposed on the liquid storage chamber, and a handle fixedly connected to the tray. The tray is provided with a steam reflux storage area, and the handle is provided with a water inlet channel. The inlet and outlet of the water inlet channel have a height difference. The water inlet channel is connected to the liquid storage chamber through the outlet, and the water inlet channel is connected to the outside through the inlet.

[0006] The above technical solution integrates the water filling path and handle structure, resulting in a simple and reasonable design. The fixed connection between the handle and the tray facilitates tray movement and allows for direct water filling via the handle without moving the tray, significantly improving the convenience of water filling and operation. This effectively solves the problems of large trays being difficult to move and adding water to the storage chamber, while also simplifying the operation process and reducing the risk of burns from moving the tray.

[0007] Compared to a handle located on the outer shell of the liquid reservoir, a handle on the tray is safer and more reliable. This is because the handle has a hollow water inlet channel, making its structural strength insufficient to support the weight of the entire cooking appliance, especially larger ones. The tray, on the other hand, is relatively lightweight, and the handle can accommodate both tray movement and water filling, resulting in a more rational structure and more reliable performance.

[0008] In conjunction with the first aspect, a further technical solution is provided whereby the entrance is equipped with a cover, which is connected to the handle, thereby enabling the entrance to be in an open or closed state.

[0009] The above technical solution prevents external impurities and dust from entering the water inlet channel and storage chamber, ensuring the cleanliness of the added water. Furthermore, the inlet can be sealed after water addition, effectively preventing accidental leakage of steam or liquid, thus improving safety and reliability.

[0010] In conjunction with the first aspect, a further technical solution is that the cover is hinged to the handle on the side near the tray, and a handle is provided on the side opposite to the hinge end of the cover, which facilitates the application of force to rotate the cover.

[0011] The above technical solution allows users to easily open or close the lid using the handle, making operation simple and convenient, and improving the user experience. Furthermore, users can quickly open and close the lid without contacting high-temperature areas, further enhancing ease of use and safety.

[0012] In conjunction with the first aspect, a further technical solution is that the tray is positioned above the liquid storage chamber, and the inlet is higher than the outlet.

[0013] The above technical solution utilizes gravity to ensure that the liquid flows smoothly from the inlet into the water inlet channel and into the storage chamber through the outlet. This ensures a smooth water filling process, improves water filling efficiency, and also prevents the liquid from accumulating or flowing back in the water inlet channel, thus guaranteeing the rationality and functionality of the structure.

[0014] In conjunction with the first aspect, a further technical solution is provided, wherein the tray is provided with a steam outlet and a closed bottom surface, the steam outlet being higher than the bottom surface, and the area between the steam outlet and the bottom surface of the tray is a steam reflux storage area.

[0015] The above technical solution can effectively collect and store the refluxed condensate, preventing steam from flowing directly into the liquid storage chamber, which would cause cross-contamination of flavors during cooking and affect the taste of the food.

[0016] In conjunction with the first aspect, a further technical solution is provided whereby the tray has a protrusion that extends above the bottom surface, and the steam outlet is located on the protrusion.

[0017] The above technical solution facilitates the discharge and circulation of steam. At the same time, the protrusion can provide a certain degree of protection for the steam outlet, preventing it from being blocked or damaged by condensed steam or foreign objects, thus further improving the stability and reliability of the product.

[0018] In conjunction with the first aspect, a further technical solution is provided in which the boss is provided with a groove surrounding the steam outlet.

[0019] The above technical solution can collect a small amount of condensate or other impurities in the groove, preventing these substances from directly entering the steam return storage area or affecting the normal discharge of steam, thus further ensuring the normal operation of the steam system and improving the quality and performance of the product.

[0020] In conjunction with the first aspect, a further technical solution is that the liquid storage chamber is connected to the steam return storage area through a steam generator and the steam outlet.

[0021] The above technical solution enables the liquid in the storage chamber to be heated by a steam generator to produce steam for cooking. After the steam is condensed, it enters the steam return storage area to prevent the condensed steam from mixing with the water in the storage chamber and improve the cooking effect.

[0022] Secondly, this application provides a handle water filling structure assembly, including the handle water filling structure of the first aspect.

[0023] By using the above technical solution, the handle water filling structure is made into an independent component, which facilitates its installation and application on different cooking utensils, improves the product's versatility and scalability, and also facilitates the production and manufacturing process, reduces production costs, and improves production efficiency.

[0024] In conjunction with the second aspect, a further technical solution is provided in which an assembly area is provided on the side of the liquid storage chamber away from the tray, and a steam generator is provided in the assembly area. One end of the steam generator is connected to the liquid storage chamber and the other end is connected to the steam return storage area.

[0025] By centrally locating the steam generator in the assembly area using the above technical solution, it is easier to install, maintain, and replace the steam generator. At the same time, it makes the layout of the entire handle water filling structure component more reasonable and compact, improving the overall performance and stability of the product, and further enhancing the product's practicality and reliability.

[0026] In summary, this application has at least one of the following beneficial technical effects:

[0027] 1. Improved the convenience of adding water and the ease of operation, solving the problems of large trays being inconvenient to move and add water.

[0028] 2. Reduces the chance of being scalded by steam during the water filling process, improving the safety and reliability of use.

[0029] 3. Reduce the backflow of condensed steam into the liquid storage chamber, which can cause the steam to be mixed with the odors of different ingredients, affecting the cooking effect. Attached Figure Description

[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] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] The inventors of this application discovered that while existing steam cookers are highly efficient, they consume steam rapidly during cooking, requiring frequent refills. However, during cooking, the tray holds the steamer basket containing the food, necessitating the removal of the tray and basket to add water to the reservoir beneath. This operation is inconvenient and increases the risk of burns. If the water-adding handle is placed on the base, its hollow water-adding channel makes it insufficient to support the weight of the entire cooking product, leading to a high failure rate and safety hazards.

[0043] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0044] Example 1

[0045] Please see Figures 1-6 The water-filling handle structure of this utility model mainly consists of a base 1, a liquid storage chamber 13, a tray 2, a handle 3, a steam generator 6, and related auxiliary components. The handle 3 is equipped with an openable and closable cap 4. All components are tightly connected to achieve the functions of convenient water filling and steam reflux.

[0046] Please see Figure 1 and Figure 2 The base 1 serves as the foundation of the entire structure, and it is equipped with a panel 11 and a liquid storage chamber 13. The panel 11 has a function adjustment knob for setting different cooking programs. The base 1 has a recess 12 to allow the handle 2 to pass over the tray 2 when it is placed on top of the liquid storage chamber 13. The liquid storage chamber 13 is located inside the base 1 and is used to store liquids (such as water).

[0047] The tray 2 is positioned above the liquid storage chamber 13, forming a vertical relationship with it. The bottom surface 25 of the tray 2 is closed, and a protrusion 22 protruding above the bottom surface 25 is provided on it. A steam outlet 5 is located on the protrusion 22. A groove 23 surrounds the steam outlet 5 around the protrusion 22 to collect condensate or other impurities, preventing these substances from directly entering the steam return storage area 21 or affecting the normal discharge of steam. The area between the steam outlet 5 and the bottom surface 25 of the tray 2 is the steam return storage area 21, used to collect and store the returned condensed steam. This prevents condensed steam carrying different food odors from directly entering the liquid storage chamber and becoming steam for secondary heating, thus affecting the cooking taste. Because the steam outlet 5 is located on the protrusion 22, and the returned condensed steam is located in the steam return storage area 21 below the steam outlet 5, the steam from the steam outlet 5 will not heat the condensate in the steam return storage area 21, effectively preventing food odor transfer. The boss 22 has a height of 15-20mm and the steam outlet 5 has a diameter of 8-10mm to ensure smooth steam flow. A 2mm gap is reserved between the groove 23 and the side wall of the boss 22 to prevent condensate from blocking the steam outlet 5 and to provide physical protection for the steam outlet 5 to avoid damage from external impacts.

[0048] Please see Figures 2-4 The handle 3 is bolted to the edge of the tray 2. A hollow water inlet channel 31 is provided inside the handle 3. The inlet 311 of the water inlet channel 31 is located on the outside of the handle 3, and the outlet 312 communicates with the liquid storage chamber 13. There is a height difference between the inlet 311 and the outlet 312, allowing the liquid to flow smoothly from the inlet 311 into the water inlet channel 31 and through the outlet 312 into the liquid storage chamber 13 using gravity. A cover 4 is installed at the inlet 311. The cover 4 is hinged to the side of the handle 3 closest to the tray 2, and a handle 41 is provided on the other side, allowing the user to easily open or close the cover 4. A rotating shaft 42 is provided inside the cover 4 for rotating the cover to open and close.

[0049] Please see Figure 3 An assembly area is located on the side of the liquid storage chamber 13 away from the tray 2, and a steam generator 6 is installed in the assembly area. One end of the steam generator 6 is connected to the liquid storage chamber 13 through a pipe, and the other end is connected to the steam return storage area 21 of the tray 2 through a steam outlet 5. The liquid in the liquid storage chamber 13 is pumped into the steam generator 6 through a water pipe and heated to generate steam. The steam enters the steam return storage area 21 through the steam outlet 5 to heat the food in the steamer above the tray 2. The condensed steam is stored at the bottom of the tray 2 to prevent it from mixing with the liquid in the liquid storage chamber 13.

[0050] In practical use, users do not need to move the tray 2. They only need to open the cover 4 on the handle 3 and inject water into the water inlet channel 31 through the inlet 311. The water will then flow into the liquid storage chamber 13 through the water inlet channel 31. After adding water, the cover 4 can be closed. The whole process is simple to operate, reduces the risk of being scalded by steam during the water adding process, and improves the safety and reliability of use.

[0051] Please see Figures 4-6 The diagram shows the open state of the cover 4. The cover 4 is rotatably connected to the handle 3 via the pivot 42. The cover 4 can be rotated open to facilitate the addition of water from the inlet 311. When cooking is underway, the cover 4 rotates to close the inlet 311 to prevent foreign objects from entering through the inlet 311 and to prevent steam from escaping through the inlet 311.

[0052] Please see Figure 6 Rotate the cap 4 to open the inlet 311, and inject clean water through the inlet 311. The liquid flows into the storage chamber 13 through the outlet 312 along the water inlet channel 31 without moving the tray 2. After adding water, press the cap 4, and the handle 3 will lock the inlet 311 to prevent steam leakage.

[0053] This utility model integrates the water inlet channel 31 into the handle 3 of the tray 2, combining the functions of "moving the tray" and "directly adding water". Utilizing the gravity-fed design where the inlet 311 is higher than the outlet 312, water can be added conveniently without disassembling the tray. The steam return storage area 21, with its structure of protrusion 22 and groove 23, effectively separates condensate from the water in the liquid storage chamber 13, improving the taste of the cooked food. The hinged handle design and diverse sealing structures of the cover 4 balance operational convenience and safety, making it suitable for modular assembly of various cooking utensils.

[0054] Example 2

[0055] The difference from Example 1 lies in our optimization of condensate treatment. A filter screen is added to the groove 23 of tray 2 to filter impurities in the condensate, ensuring its cleanliness. Furthermore, a drain outlet is located at the bottom of groove 23, connected to the storage chamber 13 via a pipe, enabling automatic backflow of condensate uncontaminated by food, thereby improving water resource utilization. This design not only enhances the product's environmental performance but also reduces the hassle of manually cleaning condensate, further improving the user experience.

[0056] Example 3

[0057] Unlike the embodiments described above, this invention also includes a visible water level window, allowing users to observe the water level in the storage chamber 13 in real time. The window is made of a high-temperature resistant transparent material, ensuring a clear display of the water level even in high-temperature environments. This design avoids insufficient steam due to insufficient water level, thus improving the user experience.

[0058] Alternatively, the water level monitoring device uses a liquid level sensor built into the water inlet channel 31 to provide real-time feedback on the water level in the storage chamber 13. When the water level is below the threshold, the panel 11 will issue a water replenishment reminder.

[0059] Example 4

[0060] Unlike the embodiments described above, to further enhance safety, a locking mechanism has been added to the connection between the lid 4 and the handle 3 to prevent the lid 4 from accidentally opening during cooking. The locking mechanism can be unlocked by pressing or rotating, ensuring that the lid 4 remains closed after water is added.

[0061] The connection between the cap 4 and the handle 3 can be either magnetic or snap-on.

[0062] Magnetic type: The inner side of the cover 4 is embedded with a ring magnet, and the handle 3 and the inlet 311 are surrounded by a metal magnetic ring. When closed, it is sealed by magnetic attraction, and when opened, it can be separated by applying lateral force, making operation easier.

[0063] Spring-loaded type: The top of the handle 3 is equipped with an elastic buckle, and the corresponding position of the cover 4 is equipped with a slot. When the cover 4 is pressed, the buckle and the slot engage. The handle part 41 has a built-in spring, which automatically springs open after being pressed, realizing quick opening and closing with one hand.

[0064] The inner wall of the water inlet channel 31 is equipped with a food-grade silicone sealing ring (not shown in the figure), and the connection between the outlet 312 and the liquid storage chamber 13 adopts a conical sealing surface to ensure no leakage during the water addition process; a high-temperature resistant rubber gasket is provided between the tray 2 and the liquid storage chamber 13 to prevent steam from overflowing from the gap between them.

[0065] Example 5

[0066] Unlike the embodiments described above, we have added an electric heating element and a temperature sensor inside the steam generator 6 for precise control of steam generation and temperature. The electric heating element is connected to an external power source via a circuit, and the temperature sensor monitors the steam temperature in real time and feeds the data back to the control system, enabling precise adjustment of the steam temperature. This design can further improve cooking results and meet the cooking needs of different ingredients.

[0067] Example 6

[0068] The difference from the above embodiments lies in the optimization of the structure of the handle 3. An anti-slip texture has been added to the outer side of the handle 3 to improve grip stability when hands are wet or in high-temperature environments. Furthermore, a filter screen has been added to the inlet 311 of the handle 3 to prevent impurities from entering the water inlet channel 31, ensuring the cleanliness of the water being added.

[0069] In addition, the handle 3 can be integrated with a temperature sensor or a water level monitoring device (not shown in the figure). The temperature sensor detects the surface temperature of the tray 2 in real time and prompts the user to avoid burns through the display screen of the panel 11 on the base 1.

[0070] Example 7

[0071] This embodiment provides a cooking appliance, including the handle-filled water structure of any of the above embodiments. A steamer is placed above the tray, and a lid is provided on the steamer. A food placement area is provided between the steamer and the lid. The steam generator can quickly generate steam, which can heat the food in the steamer. When the water is insufficient, water can be added to the liquid storage chamber through the handle, achieving a fast, safe, and convenient cooking effect.

[0072] The above provides a detailed description of the handle-type water-filling structure provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model.
