Description

Technical Field

[0001] The utility model relates to the technical field of steamers, and more specifically, to an evaporation pan structure and a steamer. Background Art

[0002] With the continuous improvement of modern families' requirements for cooking efficiency and healthy diet, as an efficient and healthy cooking device, a steamer is a kitchen appliance that heats water through an evaporation pan to convert it into high-temperature steam for 100% steam cooking of food. It has functions such as precise temperature control, locking in nutrients, reducing fat and salt, maintaining the original flavor and freshness of food, and is gradually accepted by more and more users.

[0003] As the core component of the steamer, the shape of the evaporation pan has an important impact on the generation, distribution of steam, and cooking effect. For this reason, a prior application with the application number 2023211862001 discloses an evaporation pan structure and a steamer. The evaporation pan structure includes an evaporation pan whose projection on the horizontal plane is a rounded rectangle. A heat conduction component is provided at the bottom of the evaporation pan, and a heating component is provided on the heat conduction component. The heat conduction component includes adjacent first and second heat conduction blocks, which are used to conduct the heat generated by the heating component to the evaporation pan to generate steam. This setting makes the structure of the evaporation pan consistent with the cavity, enables the uniform distribution of steam and high space utilization rate, but has deficiencies such as low heat conduction efficiency.

[0004] Therefore, the present utility model is specifically proposed. Summary of the Utility Model

[0005] The problem solved by the present utility model is that the unreasonable structure of the existing evaporation pan leads to low heat conduction efficiency, which affects the cooking effect of food.

[0006] To solve the above problems, the present utility model provides an evaporation pan structure provided on a steamer, including an evaporation pan, a heat conduction component, and a heating component. The heat conduction component is provided at the bottom of the evaporation pan. The evaporation pan includes a bottom plate in the shape of a rounded rectangle, and a disk wall is provided on the periphery of the bottom plate. The side part of the heat conduction component is attached to a part of the disk wall, and the bottom surface part of the heat conduction component protrudes away from the evaporation pan to form an avoidance space for accommodating the heating component. This setting can enable the heat conduction component to partially cover the evaporation pan, make full use of the bottom space of the evaporation pan and have good heat conduction performance. The heat generated by the heating component is not easily dispersed to the left and right sides, and at the same time, the mold opening materials are reduced.

[0007] Preferably, the disc wall includes a first wall and a second wall connected to each other. The projections of the first wall and the second wall on the horizontal plane are rounded rectangles, and a stepped structure is formed therebetween. The upper edge of the heat conduction component abuts against the stepped structure. This setting makes the heat conduction component fit closely to the bottom of the evaporation disc, and can conduct heat from both the bottom and the side of the evaporation disc, with high heat conduction efficiency.

[0008] Preferably, a water injection pipe is provided on one side of the second wall. This setting will not interfere with the assembly of the heat conduction component, has a simple structure, and is convenient for production and processing.

[0009] Preferably, the projections of both ends of the evaporation disc on the horizontal plane are semicircles, and the water outlet of the water injection pipe is horizontally arranged and faces the tangent direction of the outer edge of the evaporation disc. This setting can make full use of the internal space of the steam box, and at the same time use the principle of hydrodynamics to generate water flow vortices on the evaporation disc to efficiently remove scale.

[0010] Preferably, the heating component includes a first heating tube and a second heating tube arranged in parallel. The first heating tube and the second heating tube are respectively electrically connected to the controller. The avoidance space includes a first annular avoidance portion and a second annular avoidance portion arranged at intervals, which are respectively used to accommodate the first heating tube and the second heating tube. This setting can improve the stability and reliability when the steam box generates steam; at the same time, steam can be generated quickly according to needs, further shortening the cooking time, and providing a good user experience. The two heating components form independent components, which can be heated independently or jointly, and the heating method can be selected according to needs. Preferably, the efficiency of generating steam by heating water is higher when the two work together. Preferably, the first heating tube and the second heating tube are resistance wire heating tubes or graphene heating tubes.

[0011] Preferably, the steam box is provided with a controller, and the heat conduction component is provided with a temperature sensor and a thermal cut-off respectively. The controller is electrically connected to the temperature sensor and the thermal cut-off. The temperature sensor can quickly transmit the detected temperature signal, and different on-off control methods can be realized through different temperature data, while the thermal cut-off can realize the functions of conduction and cut-off.

[0012] Preferably, there are two temperature sensors, which are respectively located on both sides of the water injection pipe and are used to detect the real-time temperature of the heat conduction component and the evaporation disc. During the power-on heating process, the temperature of the corresponding position is monitored in real time. When the temperature sensor of the evaporation disc changes significantly, it means that the water level in the evaporation disc is close to the bottom of the disc. At this time, the controller injects a certain amount of water through the water injection pipe according to the set program, so as to avoid dry burning of the evaporation disc.

[0013] Preferably, the temperature sensor includes a sensing rod embedded inside the heat conducting component. This setting can further reduce heat loss. Due to faster heat conduction, the effect of sensing the temperature change of the heat conducting component is better, achieving the purpose of quickly and accurately transmitting temperature signals. The installation method of the temperature sensor can be surface mounting, screw mounting after opening a hole in the side wall, fixed mounting with a support frame, etc.

[0014] Compared with the prior art, the evaporation pan structure of the present utility model has the following beneficial effects: 1) The evaporation pan structure can make full use of the internal space of the steamer, making the evaporation pan more coordinated with its matching steamer cavity, and having strong selectivity to meet the cooking needs of different users; 2) By covering the bottom of the evaporation pan with a heat conducting component, heat conduction can be carried out on both the bottom surface and the side surface of the evaporation pan simultaneously, with high heat transfer efficiency, which helps to improve the cooking performance of the steamer; 3) Simple assembly, reliable structure, and good user experience.

[0015] The present utility model also provides a steamer, including the above-mentioned evaporation pan structure. The steamer has the same beneficial effects as the evaporation pan structure, which will not be elaborated here. Description of the Drawings

[0027] As Figures 1-5 shown, an evaporation pan structure is provided on a steaming box, including an evaporation pan 1, a heat conduction component 2, and a heating component 3. The heat conduction component 2 is disposed at the bottom of the evaporation pan 1. The evaporation pan 1 includes a bottom plate 11 in a rounded rectangular shape. A disk wall 12 is provided on the periphery of the bottom plate 11. The side part of the heat conduction component 2 is attached to a part of the disk wall 12. The bottom surface part of the heat conduction component 2 protrudes away from the evaporation pan 1 to form an avoidance space 21 for accommodating the heating component 3. This setting enables the heat conduction component 2 to partially cover the evaporation pan 1, making full use of the bottom space of the evaporation pan 1 and having good heat conduction performance.

[0028] Preferably, the heat conduction component 2 is made of a metal material such as aluminum, and the heat conduction component 2 is connected to the evaporation pan 1 by welding. As an example of the present invention, the pan wall 12 includes a connected first wall 121 and second wall 122. The projections of the first wall 121 and the second wall 122 on the horizontal plane are rounded rectangles and a stepped structure is formed between the two. The upper edge of the heat conduction component 2 abuts against the stepped structure. This setting makes the heat conduction component 2 fit closely to the bottom of the evaporation pan 1, and can conduct heat from both the bottom and the side of the evaporation pan 1, with high heat conduction efficiency. Preferably, the pan wall 12 further includes a connecting plate 123 arranged horizontally. The two ends of the connecting plate 123 are respectively connected to the first wall 121 and the second wall 122. The first wall 121 is connected to the bottom plate 11, and a water injection pipe 13 is arranged on one side of the second wall 122. This setting has a simple structure and is convenient for production technicians. Preferably, the pan wall 12 is integrally formed. Preferably, the evaporation pan 1 includes a flanging 14, and the flanging 14 is located at one end of the second wall 122 away from the first wall 121. This setting can enhance the mechanical strength of the evaporation pan 1 and is convenient for processing.

[0029] Preferably, the projections of both ends of the evaporation pan 1 on the horizontal plane are semi-circular, and the water outlet of the water injection pipe 13 is horizontally arranged and faces the tangential direction of the outer edge of the evaporation pan 1. This setting can make full use of the internal space of the steaming box, and at the same time generate a water flow vortex on the evaporation pan 1 by using the principle of water flow dynamics to efficiently remove scale.

[0030] Preferably, the steaming box is provided with a controller, and the heat conduction component 2 is provided with a temperature sensor 4 and a thermal cut-off 5 respectively. The controller is electrically connected to the temperature sensor 4 and the thermal cut-off 5. The temperature sensor 4 can quickly transmit the detected temperature signal, and different on-off control methods can be realized through different temperature data, while the thermal cut-off 5 can be used to realize the functions of conduction and cutting off.

[0031] As an example of the present utility model, the temperature sensor 4 includes a sensing rod embedded inside the heat conduction component 2. This setting can further reduce heat loss. Due to faster heat conduction, the effect of sensing the temperature change of the heat conduction component 2 is better, achieving the purpose of quickly and accurately transmitting the temperature signal. The installation method of the temperature sensor 4 can be surface mounting, screw mounting after opening a hole on the side wall, and fixing installation with a support frame, etc.

[0032] Preferably, there are two temperature sensors 4 and they are respectively located on both sides of the water injection pipe 13 for detecting the real-time temperature of the heat conduction component 2 and the evaporation pan 1. During the power-on heating process, the temperature of the corresponding position is monitored in real time. When the temperature in the evaporation pan 1 changes significantly, it indicates that the water level in the evaporation pan 1 is close to the bottom plate 11. At this time, the controller injects a certain amount of water through the water injection pipe 13 according to the set program, thereby avoiding dry burning of the evaporation pan 1.

[0033] As an example of the present utility model, the heating assembly 3 includes a first heating tube 31 and a second heating tube 32 which are arranged in parallel. The first heating tube 31 and the second heating tube 32 are respectively electrically connected to the controller. The avoidance space 21 includes a first annular avoidance portion 211 and a second annular avoidance portion 212 which are arranged at intervals, and are respectively used for accommodating the first heating tube 31 and the second heating tube 32. This setting can improve the stability and reliability when the steam box generates steam; at the same time, steam can be quickly generated as needed, further shortening the cooking time, and the user experience is good. The first heating tube 31 can be a resistance wire heating tube, a graphene heating tube, or an electromagnetic heating coil, a heating film, etc.

[0034] As an example of the present utility model, the first annular avoidance portion 211 and the second annular avoidance portion 212 are provided with notches 213. This setting enables the heat conduction assembly 2 to have a certain deformation space, so as to better adapt to the evaporation pan 1. At the same time, the notches 213 can reduce the heat conduction at the avoidance space 21, so that more heat is conducted to the evaporation pan 1, and the heat transfer efficiency is high.

[0035] Preferably, an installation portion 22 is formed inside the first annular avoidance portion 211 for assembling the thermal cut-off 5, and there are multiple thermal cut-offs 5. This setting makes the thermal cut-off 5 not protrude outside the heat conduction assembly 2, and the first annular avoidance portion 211 can form a shield for the thermal cut-off 5 for protection. Preferably, a support platform 23 is provided on the second annular avoidance portion 212 on the side close to the water injection pipe 13 for installing and fixing the temperature sensor 4.
