Rice cooker cover and steaming equipment

Abstract

The present invention provides a rice cooker lid and steaming device. Condensed water is generated within the steam valve mounting portion. Liquid condensed water flows along the steam valve mounting portion to the water receiving portion of the heat-insulating cover. Heat generated by the heating device acts on the water receiving portion, converting the condensed water within the water receiving portion into water vapor, which is then discharged to the outside. This arrangement effectively reduces the amount of water that flows back from the steam valve into the food, thereby improving the taste of the resulting food and enhancing the user experience.

Description

Technical Field

[0001] The invention relates to the technical field of steaming equipment, in particular to an electric rice cooker. Background Art

[0002] In daily cooking processes, steaming equipment is usually used to steam or boil food. In order to achieve the steaming or boiling operation, steam usually needs to be generated in the steaming equipment during the cooking process.

[0003] In order to draw out excess steam from the steaming device and avoid excessive steam or excessive air pressure inside the steaming device, the steaming device in the prior art usually needs to be equipped with a steam valve inside the steaming device to draw out the excess steam through the steam valve.

[0004] However, steam condenses inside the steam valve, and the resulting condensed water will flow back through the steam valve into the steaming device, adversely affecting the ingredients inside. Specifically, when steaming rice, if the condensed water flows back into the steaming device, it will cause excessive water in the rice, affecting the final taste of the rice. At the same time, when the user opens the lid of the steaming device, the excessive condensed water will flow, affecting the user experience. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the steaming equipment in the prior art easily generates condensed water during the steaming process, which has adverse effects on food ingredients and users.

[0006] To this end, the present invention provides a rice cooker lid, comprising: a main body, on which is disposed a steam valve mounting portion adapted to receive a steam valve cover; a heat-insulating cover disposed on a side of the main body away from the steam valve cover; and a water-receiving portion disposed on the heat-insulating cover, corresponding to the steam valve mounting portion and located downstream of the steam valve mounting portion in the direction of condensed water flow.

[0007] The rice cooker cover provided by the present invention further comprises a heating device, which is arranged inside the main body and is suitable for heating the water containing part.

[0008] In the rice cooker cover provided by the present invention, the water holding portion is a groove arranged on the heat-insulating cover plate.

[0009] The rice cooker cover provided by the present invention further comprises a steam valve sealing ring, one side of which rests on the heat-insulating cover plate.

[0010] In the present invention, one side of the steam valve sealing ring rests against the groove.

[0011] The rice cooker cover provided by the present invention further comprises a steam valve fixing seat, which is arranged inside the steam valve mounting portion, and one end of the steam valve fixing seat is pressed against the other side of the steam valve sealing ring.

[0012] In the rice cooker lid provided by the present invention, a step is provided on the inner wall of the steam valve sealing ring, and the step supports the steam valve fixing seat.

[0013] The rice cooker cover provided by the present invention further comprises an inner cover, wherein the steam valve sealing ring is arranged between the inner cover and the heat-insulating cover plate.

[0014] In the rice cooker cover provided by the present invention, an annular embedded portion is provided on the steam valve sealing ring, and the inner cover is suitable for being installed inside the annular embedded portion.

[0015] The rice cooker cover provided by the present invention further comprises: a heat-insulating bottom plate, and the heating device is arranged between the heat-insulating bottom plate and the inner cover.

[0016] The rice cooker cover provided by the present invention has a heating device which is a resistance wire arranged in a ring shape.

[0017] The invention provides a steaming device comprising the rice cooker cover provided by the invention.

[0018] The steaming equipment is an electric rice cooker.

[0019] The technical solution of the present invention has the following advantages:

[0020] 1. The rice cooker cover provided by the present invention includes: a main body, on which a steam valve mounting portion is provided, and the steam valve mounting portion is suitable for mounting a steam valve cover; a heat-insulating cover plate, which is arranged on a side of the main body away from the steam valve cover; a water holding portion, which is arranged on the heat-insulating cover plate, corresponds to the steam valve mounting portion, and is located downstream of the flow direction of condensed water inside the steam valve mounting portion.

[0021] In the present invention, condensed water will be generated inside the steam valve installation part, and the liquid condensed water will flow along the steam valve installation part to the water receiving part of the thermal insulation cover plate. The condensed water can be stored through the water receiving part, thereby preventing the condensed water from directly entering the rice and affecting the taste of the rice.

[0022] 2. The rice cooker cover provided by the present invention further includes: a heating device, which is arranged inside the main body and is suitable for heating the water containing part.

[0023] The heat generated by the heating device acts on the water container, turning the condensed water inside into steam and discharging it to the outside. This prevents the condensed water in the water container from being shaken and falling into the rice in the inner pot, which would adversely affect the taste of the rice.

[0024] 3. In the rice cooker lid provided by the present invention, the water-receiving portion is a groove provided on the heat-insulating cover. The groove can better collect condensed water, thereby helping to improve the subsequent heating and evaporation of the condensed water itself, and ultimately helping to improve the taste of the food.

[0025] 4. The rice cooker cover provided by the present invention further comprises: a steam valve sealing ring, one side of which rests against the heat-insulating cover plate.

[0026] By providing a steam valve sealing ring, one side of which acts on the heat-insulating cover plate, water vapor can be prevented from entering the interior of the rice cooker cover through the area between the heat-insulating cover plate and the steam valve fixing seat, thereby preventing the water vapor from damaging the electrical components inside the rice cooker cover plate. The steam valve sealing ring can effectively prevent water vapor from entering the interior of the rice cooker cover plate through the area between the heat-insulating cover plate and the steam valve fixing seat.

[0027] 5. In the rice cooker lid provided by the present invention, one side of the steam valve sealing ring acts in the groove, thereby blocking condensed water from entering the groove and confining the condensed water to the area where the steam valve sealing ring is located, thereby preventing excessive movement of the condensed water. This arrangement allows the condensed water to be collected in a small area, thereby facilitating subsequent heating operations. Furthermore, this small area of ​​collection prevents the condensed water from spreading too widely and causing adverse effects on the rice cooker lid.

[0028] 6. The rice cooker lid provided by the present invention further includes a steam valve fixing seat, which is arranged inside the steam valve installation portion, and one end of the steam valve fixing seat is pressed against the other side of the steam valve sealing ring.

[0029] By setting up a steam valve fixing seat, the stability of the steam valve sealing ring itself can be effectively improved, preventing it from deforming during use and eventually losing contact with the groove, thereby affecting the normal collection operation of the steam valve sealing ring on condensed water.

[0030] 7. In the rice cooker lid provided by the present invention, the steam valve sealing ring is provided with an annular embedded portion, and the inner cover is suitable for being installed inside the annular embedded portion.

[0031] By providing the annular embedded portion, the structure of the inner cover can be effectively utilized, thereby achieving the fixing operation of the steam valve sealing ring with the help of the inner cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Example 1

[0044] This embodiment provides a rice cooker cover, such as Figures 1-4 As shown, including:

[0045] A main body 8, on which a steam valve mounting portion is provided, wherein the steam valve mounting portion is suitable for mounting a steam valve cover 7;

[0046] Specifically, the steam valve mounting portion itself can be a through hole set along the thickness direction of the rice cooker cover body, and a steam valve cover 7 is set on the side of the steam valve mounting portion in contact with the outside world. The steam valve cover 7 refers to a structure that can discharge water vapor from the rice cooker cover body.

[0047] The heat-insulating cover plate 1 is arranged on a side of the main body 8 away from the steam valve cover 7;

[0048] Specifically, the heat-insulating cover plate 1 itself is arranged on a side away from the steam valve cover 7 and is in direct contact with the water vapor.

[0049] The water container 11 is provided on the heat-insulating cover plate 1, corresponds to the steam valve installation portion, and is located downstream of the condensed water flow direction inside the steam valve installation portion;

[0050] The structure of the water receiving portion 11 itself is not limited, as long as it can accommodate the condensed water. Specifically, it can be a pit itself, or a water receiving portion provided on the inner wall of the steam valve mounting portion, as long as it can accommodate the condensed water itself.

[0051] There is no limitation on the position of the water container 11 on the heat-insulating cover plate 1. The water container 11 can be located at the center of the heat-insulating cover plate 1 or at an eccentric position of the heat-insulating cover plate 1. Figure 3 As shown, the water containing portion 11 is arranged at an eccentric position of the thermal insulation cover plate 1 .

[0052] The water storage part can be used to store condensed water, thereby preventing the condensed water from directly entering the rice and affecting the taste of the rice.

[0053] Furthermore, this embodiment includes a heating device disposed within the main body 8 and adapted to heat the water container 11. The heat generated by the heating device acts on the water container, converting condensed water within the container into steam and discharging it to the outside. This prevents condensed water in the container from being shaken and falling into the rice in the inner pot, negatively affecting the rice's taste.

[0054] In this embodiment, there are no excessive restrictions on the structure and specific location of the heating device itself, as long as the heating operation of the water containing portion 11 itself can be achieved.

[0055] As a preferred embodiment, the heating device is a resistance wire 2 arranged in a ring shape.

[0056] As a preferred embodiment, in the rice cooker cover provided in this embodiment, the water holding portion 11 is a groove provided on the heat-insulating cover plate 1 .

[0057] Specifically, the groove itself can be a continuous structure or a discontinuous structure. There is no limitation on the shape of the groove itself, and it can be circular, elliptical, rectangular, etc.

[0058] As a preferred embodiment, in this embodiment, Figure 3 and Figure 4 As shown, the groove itself is arranged in an annular shape and is arranged continuously on the entire thermal insulation cover plate 1. At the same time, the groove itself is a circular structure.

[0059] The rice cooker lid provided in this embodiment further includes: a steam valve sealing ring 4, one side of which abuts against the thermal insulation cover plate 1. By providing the steam valve sealing ring 4, with one side acting on the thermal insulation cover plate 1, water vapor is prevented from entering the rice cooker lid through the area between the thermal insulation cover plate 1 and the steam valve fixing seat 6, thereby preventing damage to the electrical components within the rice cooker lid. The steam valve sealing ring 4 effectively provides a barrier.

[0060] In this embodiment, the position where the steam valve sealing ring 4 rests on the heat-insulating cover plate 1 is not limited, as long as it can play a blocking role. As a preferred embodiment, one side of the steam valve sealing ring 4 acts in the groove, thereby blocking the condensed water entering the interior of the groove, and limiting the condensed water to the area where the steam valve sealing ring 4 is located, thereby preventing the condensed water from moving too much. The above-mentioned setting method allows the condensed water itself to be collected in a small range, thereby facilitating subsequent heating operations. At the same time, gathering in a small range can prevent the condensed water from covering too large a range and causing adverse effects on the rice cooker cover. Specifically, the steam valve sealing ring 4 can rest against the center of the width of the groove, and can also rest against the part of the groove that deviates from the center of the width. In this embodiment, no excessive restrictions are imposed.

[0061] Specifically, the steam valve sealing ring 4 itself is made of a flexible material, such as rubber. During the assembly process, the steam valve sealing ring 4 itself will be deformed, specifically, Figure 4 As shown, the steam valve sealing ring 4 itself will form an opening toward the center of the rice cooker cover, and the condensed water formed inside the rice cooker cover will enter the area formed between the steam valve sealing ring 4 and the insulation cover plate 1.

[0062] In this embodiment, Figure 3 As shown, it also includes a steam valve fixing seat 6, which is arranged inside the steam valve installation portion, and one end of the steam valve fixing seat 6 is pressed against the other side of the steam valve sealing ring 4.

[0063] The steam valve holder 6 is cylindrical in shape, with its bottom end pressed against the top of the steam valve seal 4. This helps stabilize the top of the steam valve seal 4. During cooking, the inner wall of the steam valve holder 6 comes into contact with high-temperature steam. This steam cools on the inner wall and forms condensate, which then flows downward along the inner wall and eventually enters the steam valve seal 4.

[0064] In this embodiment, the assembly method between the steam valve fixing seat 6 and the steam valve sealing ring 4 is not limited. As a preferred embodiment, a step is provided on the inner wall of the steam valve sealing ring 4. The step protrudes from the inner wall of the steam valve sealing ring 4 and is annular in shape, supporting the bottom of the steam valve fixing seat 6.

[0065] In this embodiment, it further includes: an inner cover 5 , and the steam valve sealing ring 4 is arranged between the inner cover 5 and the thermal insulation cover plate 1 .

[0066] Furthermore, in order to achieve stability between the inner cover 5 and the steam valve sealing ring 4, an annular embedded portion is provided on the steam valve sealing ring 4, and the inner cover 5 is suitable for being installed inside the annular embedded portion.

[0067] Specifically, the annular embedded portion itself is arranged at the top outer edge of the steam valve sealing ring 4, and is arranged in an annular shape. The annular embedded portion itself is arranged in a concave shape, and a protrusion is correspondingly arranged on the inner cover 5. The protrusion enters the annular embedded portion to realize the connection action.

[0068] The rice cooker cover provided in this embodiment further includes: a heat-insulating bottom plate 3 , and the heating device is arranged between the heat-insulating bottom plate 3 and the inner cover 5 .

[0069] The insulating base plate 3 secures the heating device. Heat generated by the heating device is transferred to the insulating cover plate 1 through the insulating base plate, further heating the condensed water on the cover plate 1. Specifically, the insulating base plate is made of a material with a high thermal conductivity, such as iron or copper. Furthermore, the insulating base plate 3 is annular in shape, providing maximum coverage of the heating device.

[0070] Furthermore, the heating device itself is made of a resistance wire 2 , which can be connected to the thermal insulation cover plate 1 by means of double-sided tape.

[0071] Example 2

[0072] This embodiment provides a steaming device, comprising the rice cooker cover provided in embodiment 1. The steaming device is an electric rice cooker, and may also be a steamer, a boiling pot, or the like.

[0073] Specifically, the steaming device includes a steaming part, and the rice cooker cover itself is rotatably arranged above the steaming part. The steaming part itself is provided with an inner pot, and the steaming operation is performed in the inner pot. Figure 4 As shown by the middle arrow A, when water vapor is generated inside the steaming part, the water vapor generated will enter the steam valve mounting part upward, then condense on the inner wall of the steam valve mounting part and flow downward along the steam valve mounting part. At this time, the water holding part located on the rice cooker lid will itself collect the condensed water. Furthermore, the heating device will heat the condensed water, so that the condensed water will fly out of the steaming equipment to the outside again in the form of vapor.

[0074] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
