Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an electric rice cooker cover and the electric rice cooker. Background Art

[0002] Currently available rice cookers have steam valve assemblies, whose primary function is to reflux and break bubbles within the steam, separating the rice soup from the steam in the mixed airflow and preventing problems such as rice soup overflowing due to excessive heating power. For example, prior art CN 104510341A discloses an electric rice cooker with a steam assembly. The steam valve assembly comprises a steam valve seat, a cover, and a steam valve cover. By installing a rotating bubble-breaking cover on the steam cylinder of the steam valve seat, the airflow exiting the steam hole on the steam valve seat passes through the airflow opening of the rotating bubble-breaking cover and drives the rotating bubble-breaking cover to rotate, thereby achieving a bubble-breaking effect. Furthermore, the airflow collides during its exit from the steam cylinder, achieving a gas-liquid separation effect. However, when the steam flow rate is high, the soup splashes out of the steam cylinder before it can separate, which can easily cause overflow, especially if the user adds too much water. The steam cylinder has a complex structure, numerous components, and requires complex tooling and processes, which increases manufacturing costs and reduces yield. Furthermore, this steam valve has a complex structure and is difficult for users to clean. Utility Model Content

[0003] The utility model provides an electric rice cooker cover, which solves the problems of high cost, inconvenient assembly and disassembly, and weak anti-overflow capability caused by the existing electric rice cooker being equipped with an independent steam valve.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rice cooker cover body, comprising: an outer cover and an inner cover detachably connected to the inner side of the outer cover; the outer cover comprises a lining cover, a surface cover covering the outer side of the lining cover and a boss integrally formed on the inner side of the surface cover, the lining cover has a through hole adapted to the boss, a steam chamber is formed between the inner cover and the boss, the surface cover has an exhaust hole connected to the steam chamber, the inner cover has an air inlet connected to the steam chamber, a sealing ring is arranged between the inner cover and the outer cover to provide sealing, and the steam chamber is located in the sealing area of the sealing ring.

[0005] After adopting the above technical solution, the utility model has the following advantages: the boss and the inner side of the cover are integrally formed and form a sealed steam chamber with the inner cover, thereby replacing the steam valve assembly, thereby saving material and assembly costs. At the same time, it also reduces the space occupied by the assembly of multiple parts, so that the capacity of the steam chamber is maximized, which means that more rice soup condensate can be contained in the steam chamber, improving the overflow prevention capability. The inner cover is detachably connected to the outer cover, and the entire steam chamber can be cleaned by simply removing the inner cover from the outer cover. This design allows the user to easily separate the inner cover from the outer cover, thereby conveniently cleaning the steam chamber. Compared with the existing technology where multiple parts may need to be disassembled to clean the steam chamber, the convenience of cleaning is significantly improved.

[0006] Furthermore, the sealing ring is fitted on the lining cover around the through hole and is pressed and fixed by the surface cover.

[0007] With the aforementioned technical solution, the inner and outer covers are sealed by adding a sealing ring at the through hole. The addition of the sealing ring significantly reduces the gap between the inner and outer covers. If these gaps are not sealed, steam and heat may leak out from these places, affecting the cooking effect. The sealing effect of the sealing ring ensures that the steam and heat can be completely retained in the steam chamber. Condensation water will be generated during the cooking process, and this condensation water will remain on the upper surface of the inner cover. If the condensation water drips from the gap between the inner and outer covers onto the food, it will affect the cooking effect and taste. The sealing effect of the sealing ring can, to a certain extent, prevent steam condensation water from seeping out from the gap between the inner and outer covers.

[0008] Furthermore, the outer edge of the inner cover extends upward to form a sealing enclosure, and the upper end of the sealing enclosure abuts against the sealing ring.

[0009] By adopting the above-mentioned technical solution, the upper edge of the inner cover extends upward to form a sealing enclosure. The sealing enclosure gives the inner cover a certain height, preventing the condensed water accumulated in the accommodating gap from spilling out when the rice cooker needs to be disassembled for cleaning, and also ensuring that the accumulated condensed water will not leak from the gap between the inner cover and the sealing ring.

[0010] Furthermore, a bracket is provided on the boss, and the inner cover is detachably connected to the boss via the bracket. The air inlet holes are circumferentially spaced around the bracket, and the height of the upper end surface of the inner cover decreases from a position close to the air inlet hole to a position away from the air inlet hole.

[0011] With the aforementioned technical solution, during the steam heating process, the steam containing rice slurry will form sticky condensation water at the air inlet of the inner cover. If not drained away in time, it may accumulate near the air inlet and cause blockage. Therefore, the height of the upper end surface of the inner cover is gradually reduced from the position close to the air inlet to the position away from the bracket, so that the upper surface of the inner cover forms a guide surface, keeping the air inlet unobstructed and ensuring that the steam can be discharged smoothly through the air inlet.

[0012] Furthermore, the upper end surface of the face cover is concave downward to form an electrical cavity with an open upper end. The electrical cavity and the face cover are an integrally formed structure. The electrical cavity is isolated from the steam cavity, and a panel for closing the electrical cavity is installed above the outer cover.

[0013] With the aforementioned technical solution, the upper end of the outer cover is concave downward, forming an electrical chamber with an open top. This allows the electrical chamber to be embedded within the outer cover, creating a relatively independent space. The electrical chamber and outer cover are integrally formed, with no additional seams or interfaces, isolating the electrical chamber from the steam chamber, preventing steam from entering the chamber. This further enhances the safety of the chamber.

[0014] Furthermore, a substrate rack is installed in the electrical cavity, and a substrate is installed on the substrate rack.

[0015] Using the aforementioned technical solution, a substrate rack is installed within the electrical cavity, providing a mounting platform for the substrate, supporting and securing it. This ensures the stability of the electrical components. The substrate rack provides support for the substrate, preventing it from moving or deforming under vibration or impact, thereby protecting the components from damage. The substrate rack is typically used to increase heat dissipation efficiency, such as by increasing the heat dissipation area, to prevent damage to the components due to overheating during prolonged operation, and to secure other electrical components.

[0016] Furthermore, a heat-insulating gap is provided between the substrate frame and the bottom surface of the electrical cavity.

[0017] With the aforementioned technical solution, an insulating gap is provided between the substrate rack and the bottom surface of the electrical cavity. This gap is designed to reduce or block direct heat transfer between the substrate rack and the bottom surface of the electrical cavity. This gap helps better control the operating temperature of the substrate rack and the electrical components mounted thereon. By reducing heat transfer to the bottom surface of the electrical cavity, performance degradation or damage to the electrical components due to overheating can be avoided. The bottom surface of the electrical cavity may contain other temperature-sensitive components or materials. The provision of the insulating gap prevents heat generated by the substrate rack and the electrical components mounted thereon from adversely affecting the bottom surface of the electrical cavity during operation.

[0018] Furthermore, a lining cover is installed below the outer cover, and the lining cover is arranged around the outer side of the inner cover.

[0019] With the above technical solution, the lining cover is installed below the outer cover and surrounds the outer side of the inner cover, so that the lining cover forms an external protection surrounding the inner cover. The main function of the lining cover is to provide additional protection and structural support.

[0020] Furthermore, a downwardly protruding fixed shaft is fixed to the lower end surface of the outer cover, and the lower end of the fixed shaft has a first limiting ring convex, and a first clamping hole is provided on the bracket, and the bracket is an elastic structure, and the first clamping hole is clamped with the first limiting ring convex, and a second clamping hole is provided on the inner cover, and a second limiting ring convex is provided on the bracket, and the second clamping hole is clamped with the second limiting ring convex.

[0021] According to the above technical solution, a downwardly protruding fixed shaft is fixed to the lower end face of the outer cover, and a first limiting ring protrusion is provided on the shaft. This allows the outer cover to be precisely positioned during installation by the fixed shaft, and the first limiting ring protrusion provides a certain limiting effect. The bracket is provided with a first snap-in hole that matches the first limiting ring protrusion, and the bracket is an elastic structure. When the outer cover is inserted into the bracket through the fixed shaft, the first limiting ring protrusion can snap into the first snap-in hole. Due to the elasticity of the bracket, this interference fit is more stable and flexible. The inner cover is provided with a second snap-in hole, and the bracket is provided with a second limiting ring protrusion that matches the second snap-in hole. This allows the inner cover to be snap-fitted with the second snap-in hole on the inner cover by the second limiting ring protrusion on the bracket during installation, further enhancing the stability of the entire structure. This multiple snap-in design makes it less likely for the rice cooker to loosen or fall off during use, improves installation efficiency, and reduces installation costs.

[0022] An electric rice cooker comprises a rice cooker body and the above-mentioned cover body, wherein the rice cooker body comprises an outer shell and an inner pot arranged in the outer shell, the cover body is pivotally connected to the rice cooker body, and when the cover body covers the rice cooker body, the sealing ring seals the pot opening of the inner pot.

[0023] By adopting the above-mentioned technical solution, the pot body has two parts, an outer shell and an inner pot, so that the inner pot is placed inside the outer shell. The internal and external isolation effectively prevents heat from being directly transferred to the external environment, thereby improving energy efficiency and reducing heat loss during the cooking process. By pivotally connecting the outer cover to the pot body, the user can easily open and close the pot body, and the sealing ring abuts against the upper edge of the inner pot and seals the inner pot. When the outer cover is closed, the pot body can be effectively sealed, effectively preventing steam and heat leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] like Figure 1 and Figure 4 As shown, a rice cooker cover body, an outer cover 1 and an inner cover 3 detachably connected to the inner side of the outer cover 1; the outer cover 1 includes a lining cover 11, a surface cover 12 covering the outer side of the lining cover 11 and a boss 13 integrally formed on the inner side of the surface cover 12, and Figure 5 As shown, the lining cover 11 has a through hole 111 adapted to the boss 13, a steam chamber 2 is formed between the inner cover 3 and the boss 13, the surface cover 12 has an exhaust hole 121 connected to the steam chamber 2, the inner cover 3 has an air inlet 31 connected to the steam chamber 2, and a sealing ring 17 is arranged between the inner cover 3 and the outer cover 1 to provide sealing, and the steam chamber 2 is located in the sealing area of the sealing ring 17.

[0032] It is understandable that the boss 13 and the inner side of the face cover 12 are integrally formed, and together with the inner cover 3, form a sealed steam chamber 2, thereby replacing the steam valve assembly, thereby saving material and assembly costs, while also reducing the space occupied by the assembly of multiple components, thereby maximizing the capacity of the steam chamber 2, which means that more rice soup condensate can be accommodated in the steam chamber 2, improving the overflow prevention capability, and the inner cover 3 is detachably connected to the outer cover 1, and the entire steam chamber 2 can be cleaned by simply removing the inner cover 3 from the outer cover 1. This design allows the user to easily separate the inner cover 3 from the outer cover 1, thereby conveniently cleaning the steam chamber 2. Compared with the prior art where multiple components may need to be disassembled to clean the steam chamber 2, this significantly improves the convenience of cleaning.

[0033] Specifically, the boss 13 has a bottom surface facing the inner cover 3 and a first cavity 14 recessed from the bottom surface toward away from the inner cover 3. The first cavity 14 constitutes at least a part of the steam chamber 2. In this way, the accommodation space of the steam chamber 2 can be increased by increasing the longitudinal space, thereby reducing the splashing of rice slurry condensation water from the steam chamber 2; a second cavity 15 is provided between the bottom surface and the inner cover 3, and the second cavity 15 is connected to the first cavity 14, further increasing the accommodation space of the steam chamber 2 by increasing the lateral space.

[0034] Specifically, the upper end surface of the outer cover 1 is concave downward to form a third cavity 16 with an open upper end, which is used to form an electrical cavity for assembling electrical components. The electrical cavity and the outer cover 1 are an integrally formed structure. The electrical cavity is isolated from the steam cavity 2. A panel for closing the electrical cavity is installed above the outer cover 1. The third cavity 16 is staggered with the first cavity 14 and is not connected. The third cavity 16 is located above the second cavity 15 and is stacked to improve space utilization.

[0035] As can be understood, the upper end of the outer cover 1 is concave downward, forming an electrical chamber with an open top. This allows the electrical chamber to be embedded within the outer cover 1, creating a relatively independent space. The electrical chamber and outer cover 1 are integrally formed, with no additional seams or interfaces, isolating the electrical chamber from the steam chamber, preventing steam from entering the electrical chamber. This further enhances the safety of the electrical chamber.

[0036] Further, such as Figure 1 As shown, a substrate rack is installed in the electrical cavity, and a substrate is installed on the substrate rack.

[0037] As you can understand, the substrate rack is installed within the electrical cavity, providing a mounting platform for the substrate, used to support and secure it. This ensures the stability of the electrical components. The substrate rack provides support for the substrate, preventing it from moving or deforming under vibration or impact, thereby protecting the electrical components from damage. The substrate rack is typically used to increase heat dissipation efficiency, such as by increasing the heat dissipation area, to prevent damage to the electrical components due to overheating during prolonged operation, and to secure other electrical components.

[0038] Furthermore, a heat-insulating gap is provided between the substrate frame and the bottom surface of the electrical cavity.

[0039] It is understood that the thermal insulation gap provided between the substrate rack and the bottom surface of the electrical cavity is intended to reduce or block direct heat transfer between the substrate rack and the bottom surface of the electrical cavity. This gap helps to better control the operating temperature of the substrate rack and the electrical components thereon. By reducing heat transfer to the bottom surface of the electrical cavity, performance degradation or damage to the electrical components due to overheating can be avoided. The bottom surface of the electrical cavity may contain other temperature-sensitive components or materials. The provision of the thermal insulation gap prevents the heat generated by the substrate rack and the electrical components thereon during operation from adversely affecting the bottom surface of the electrical cavity.

[0040] Specifically, if Figure 3 As shown, a smart panel 4 for user convenience is provided above the third cavity 16. The smart panel 4 is fixed to the outer cover 1 by fixing bolts or gluing. A control button 41 and a switch button 42 are installed on the upper surface of the smart panel 4. The control button 41 and the switch button 42 are electrically connected to the main control board. A light source is provided at the lower end of the control button 41, which may be an LED indicator light, etc. The light source is also electrically connected to the main control board. When selecting a function, the light source emits light, and an aperture can be observed from the control button 41, so that the current usage status of the rice cooker can be judged according to the state of the aperture.

[0041] Specifically, the smart panel 4 may also be provided with a data display screen for displaying the cooking time and other functions.

[0042] As a preferred Figure 1 As shown, the sealing ring 17 is fitted on the lining cover 11 around the through hole 111 and is pressed and fixed by the surface cover 12 .

[0043] It is understandable that the inner cover 3 and the outer cover 1 are sealed by adding a sealing ring 17 at the through hole. The sealing ring 17 is usually made of a soft and high-temperature resistant material, such as silicone or rubber. The addition of the sealing ring 17 significantly reduces the gap between the inner and outer covers 1. If these gaps are not sealed, steam and heat may leak out from these places, affecting the cooking effect. The sealing effect of the sealing ring 17 ensures that the steam and heat can be completely retained in the steam chamber 2. Condensation water will be generated during the cooking process, and this condensation water will remain on the upper surface of the inner cover 3. If the condensation water drips from the gap between the inner cover 3 and the outer cover 1 onto the food, it will affect the cooking effect and taste. The sealing effect of the sealing ring 17 can prevent steam condensation water from seeping out from the gap between the inner and outer covers 1 to a certain extent.

[0044] Preferably, the sealing ring 17 is fitted on the lining cover 11 around the through hole 111 and is pressed and fixed by the surface cover 12 .

[0045] It can be understood that the upper edge of the inner cover 3 extends upward to form a sealing enclosure 32. The sealing enclosure 32 gives the inner cover 3 a certain height, preventing the condensed water accumulated in the accommodating gap 33 from spilling out when the rice cooker needs to be disassembled for cleaning, and also ensuring that the accumulated condensed water will not leak from the gap between the inner cover 3 and the sealing ring 17.

[0046] Further, such as Figure 1 and Figure 2 As shown, a bracket 131 is provided on the boss 13, and the inner cover 3 is detachably connected to the boss 13 through the bracket 131. The air inlet holes 31 are circumferentially spaced around the bracket 131, and the height of the upper end surface of the inner cover 3 decreases from a position close to the air inlet holes 31 to a position away from the bracket 131.

[0047] It is understandable that during the steam heating process, the steam containing rice slurry will form sticky condensation water at the air inlet 31 of the inner cover 3. If not drained away in time, it may accumulate near the air inlet 31 and cause blockage. Therefore, the height of the upper end surface of the inner cover 3 is gradually reduced from the position close to the air inlet 31 to the position away from the bracket 131, so that the upper surface of the inner cover 3 forms a guide surface, keeping the air inlet 31 unobstructed and ensuring that the steam can be discharged smoothly through the air inlet 31.

[0048] Furthermore, a lining cover 11 is installed below the outer cover 1 , and the lining cover 11 is arranged around the outer side of the inner cover 3 .

[0049] It is understandable that the lining cover 11 is installed below the outer cover 1 and is arranged around the outer side of the inner cover 3. The lining cover 11 forms an external protection surrounding the inner cover 3. The main function of the lining cover 11 is to provide additional protection and structural support.

[0050] Further, such as Figure 2 As shown, a downwardly protruding fixed shaft 18 is fixed to the lower end surface of the outer cover 1, and the lower end of the fixed shaft 18 has a first limiting ring protrusion 19, and a first clamping hole 132 is provided on the bracket 131, and the bracket 131 is an elastic structure. The first clamping hole 132 is clamped with the first limiting ring protrusion 19, and a second clamping hole 35 is provided on the inner cover 3, and a second limiting ring protrusion 133 is provided on the bracket 131. The second clamping hole 35 is clamped with the second limiting ring protrusion 133, and the fixed shaft 18 is arranged in the middle position of the outer cover 1.

[0051] It is understandable that a downwardly protruding fixed shaft 18 is fixed to the lower end face of the outer cover 1, and a first limiting ring protrusion 19 is provided on the shaft. This allows the outer cover 1 to be accurately positioned by the fixed shaft 18 during installation, and the first limiting ring protrusion 19 provides a certain limiting effect. The bracket 131 is provided with a first snap-fitting hole 132 that matches the first limiting ring protrusion 19, and the bracket 131 is an elastic structure. When the outer cover 1 is inserted into the bracket 131 through the fixed shaft 18, the first limiting ring protrusion 19 can be snapped into the first snap-fitting hole 132. Due to the elasticity of the bracket 131, this interference fit is more stable and flexible. The inner cover 3 is provided with a second snap-fitting hole 35, and the bracket 131 is provided with a second limiting ring protrusion 133 that matches the second snap-fitting hole 35. When installing, the inner cover 3 can also be clamped with the second clamping hole 35 on the inner cover 3 through the second limiting ring protrusion 133 on the bracket 131, further enhancing the stability of the entire structure. This multiple clamping design makes it difficult for the rice cooker to loosen or fall off during use, improves installation efficiency, and reduces installation costs.

[0052] Specifically, the inner cover 3 is detachably connected to the boss 13 through the bracket 131. The bracket 131 and the boss 13 can be an integrally formed structure, or they can be connected by fixing screws or welding. The bracket 131 can also be provided with a food-grade silicone gasket for installation and fixation through interference fit with the inner cover 3.

[0053] Example 2:

[0054] An electric rice cooker comprises a rice cooker body and the cover body described in Example 1. Furthermore, the rice cooker body comprises an outer shell and an inner pot arranged in the outer shell. The cover body is pivotally connected to the rice cooker body. When the cover body covers the rice cooker body, the sealing ring 17 seals the pot mouth of the inner pot.

[0055] It can be understood that the pot body has two parts, an outer shell and an inner pot, so that the inner pot is placed inside the outer shell. The internal and external isolation effectively prevents heat from being directly transferred to the external environment, thereby improving energy efficiency and reducing heat loss during the cooking process. The outer cover 1 is pivotally connected to the pot body, and the user can easily open and close the pot body. The sealing ring 17 abuts against the upper edge of the inner pot and seals the inner pot. When the outer cover 1 is closed, the pot body can be effectively sealed, effectively preventing steam and heat leakage.
