Description
Technical Field
[0001] This utility model relates to the field of cooking utensils, and in particular to a gas valve assembly for an electric rice cooker and an electric rice cooker using the gas valve assembly. Background Technology
[0002] With social development and the continuous progress of science and technology, rice cookers have become a common cooking appliance in people's homes.
[0003] A typical rice cooker consists of the following structure: a main body containing an inner pot for holding food; a heating element at the bottom of the main body for heating the inner pot; and a rotating lid at the top of the main body, which opens and closes. The lid includes a gas valve assembly. When the rice cooker is used for cooking, the steam generated inside can be directly released through the gas valve assembly, preventing excessive pressure buildup inside the rice cooker.
[0004] The gas valve assembly of existing rice cookers generally adopts a straight-through design. During the cooking process, a large amount of steam is released from inside the rice cooker, which affects both the cooking effect and the taste of the food. Utility Model Content
[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, the first aspect of this invention provides a rice cooker gas valve assembly that allows the gas valve assembly to open and release gas only when the pressure inside the rice cooker reaches a set value, thus helping to solve the technical problem of excessive gas release affecting the cooking efficiency of the rice cooker; the second aspect of this invention provides a rice cooker using the above-mentioned gas valve assembly, which helps to improve the cooking efficiency of the rice cooker.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a gas valve assembly for an electric rice cooker, including a gas valve base and a gravity seal. A gas valve cover is detachably installed on the upper part of the gas valve base. The gas valve base and the gas valve cover are spliced to form a gas valve body. A receiving cavity is opened inside the gas valve body. An air inlet channel communicating with the receiving cavity is opened at the lower part of the gas valve base. An air outlet channel communicating with the receiving cavity is opened on the side wall or upper surface of the gas valve cover. The gravity seal is located inside the receiving cavity and is movably installed at the connection port communicating with the receiving cavity through the air inlet channel. The gravity seal can close the connection port under the action of gravity.
[0007] The beneficial effects of a gas valve assembly for a rice cooker according to certain embodiments of this utility model are as follows:
[0008] This embodiment of a rice cooker gas valve assembly features a gravity seal movably installed within a cavity inside the gas valve body. The gravity seal is located at the connection point between the gas valve body's inlet channel and the cavity. In its initial state, the gravity seal closes the inlet channel's connection point under gravity, keeping the gas valve assembly closed and preventing venting. When the internal pressure of the rice cooker using this embodiment's gas valve assembly exceeds a set value, the gas pushes the gravity seal upwards relative to the gas valve base, opening the connection point. At this point, the gas inlet channel is open, allowing gas to flow into the gas valve body's cavity and finally exit through the outlet channel, thus venting and releasing pressure. When the internal pressure is below the set value, the gravity seal moves downwards relative to the gas valve base under gravity, closing the connection point and shutting off the gas valve assembly. The rice cooker then stops venting and releasing pressure, maintaining stable internal pressure and achieving a pressure-holding effect. By adopting the above structure, the rice cooker gas valve assembly of this embodiment will only open to release gas when the internal pressure of the rice cooker reaches a set value, which helps to solve the technical problem that the direct and large amount of gas in the rice cooker will affect the cooking efficiency of the rice cooker.
[0009] In some embodiments of this utility model, the valve base is provided with a cover member covering the outer periphery of the communication port, the gravity seal member is located inside the cover member, and the gravity seal member can move relative to the cover member to open or close the communication port, and the side wall of the cover member is provided with at least one hollow hole.

[0017] An electric rice cooker according to certain embodiments of the present invention includes a rice cooker lid, wherein the rice cooker lid is equipped with the above-mentioned electric rice cooker gas valve assembly.
[0018] The beneficial effects of a rice cooker according to certain embodiments of this utility model:
[0019] This embodiment of the rice cooker, by configuring the rice cooker lid with the aforementioned rice cooker gas valve assembly, ensures that the gas valve assembly only opens to release pressure when the internal pressure of the rice cooker reaches a set value. When the internal pressure of the rice cooker is less than the set value, the gas valve assembly automatically closes without releasing pressure, thus maintaining a stable internal pressure and achieving a pressure-holding function. This helps to solve the technical problem of existing rice cookers where a large amount of gas is directly released, affecting the cooking efficiency of the rice cooker. Attached Figure Description

[0034] Figures 1 to 8 This is a schematic diagram of some embodiments of the gas valve assembly of an electric rice cooker according to the present invention.
[0035] Reference Figures 1 to 8 and mainly refer to Figure 3 , Figure 4 and Figure 5 According to certain embodiments of this utility model, a gas valve assembly for a rice cooker (hereinafter referred to as "gas valve assembly" for ease of explanation) includes a gas valve base 110 and a gravity seal 200. A gas valve cover 120 is detachably mounted on the upper part of the gas valve base 110. The gas valve base 110 and the gas valve cover 120 are joined to form a gas valve body 100, and a receiving cavity 130 is formed inside the gas valve body 100. In this embodiment, the gas valve cover 120 covers the upper part of the gas valve base 110, and the interior of the gas valve cover 120 and the interior of the gas valve base 110 are joined to form the aforementioned receiving cavity 130. An air inlet channel 111 communicating with the receiving cavity 130 is formed at the lower part of the gas valve base 110, allowing external gas to enter the receiving cavity 130 through the air inlet channel 111. The side wall or upper surface of the valve cover 120 is provided with an air outlet channel 121 that communicates with the receiving cavity 130. Gas inside the receiving cavity 130 can be discharged to the outside of the valve body 100 through the air outlet channel 121. A gravity seal 200 is located inside the receiving cavity 130 and is movably installed at the connection port 112 connecting the air inlet channel 111 and the receiving cavity 130. Under the action of gravity, the gravity seal 200 can close the connection port 112. In this embodiment, the gravity seal 200 is a spherical component with a certain weight. Specifically, the gravity seal 200 is a steel ball or glass ball, etc. The gravity seal 200 is movably placed inside the receiving cavity 130 and is located at the connection port 112. Under the action of gravity, the gravity seal 200 presses and seals the connection port 112.
[0036] When the rice cooker uses the gas valve assembly of this embodiment, in its initial state, the gravity seal 200 closes the connection port 112 of the air inlet channel 111 under the action of gravity. At this time, the rice cooker gas valve assembly is in a closed state and cannot exhaust gas. When the pressure inside the rice cooker using the gas valve assembly of this embodiment is greater than a set value, the thrust exerted by the gas inside the rice cooker on the gravity seal 200 is greater than the weight of the gravity seal 200 itself. The gas pushes the gravity seal 200 to move upward relative to the gas valve base 110 and open the connection port 112. At this time, the rice cooker gas valve assembly... With the air inlet channel 111 open, gas inside the rice cooker can flow into the receiving cavity 130 of the gas valve body 100 through the air inlet channel 111 and finally exit through the air outlet channel 121, achieving gas exhaust and pressure relief. When the pressure inside the rice cooker is lower than the set value, the thrust exerted by the gas inside the rice cooker on the gravity seal 200 is less than the weight of the gravity seal 200 itself. Under the action of gravity, the gravity seal 200 moves downward relative to the gas valve base 110 and closes the connecting port 112, thereby closing the rice cooker gas valve assembly. The rice cooker gas valve assembly no longer exhausts gas and relieves pressure, thus keeping the gas pressure inside the rice cooker stable and achieving the function of pressure maintenance. By adopting the above structure, the rice cooker gas valve assembly using the rice cooker gas valve assembly of this embodiment only opens to exhaust gas when the pressure inside the rice cooker reaches the set value, which helps to solve the technical problem of the direct and large-scale exhaust of gas inside the rice cooker affecting the cooking efficiency of the rice cooker.
[0037] Reference Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 To prevent the gravity seal 200 from moving away from the air intake channel 111 and failing to fall back to the connecting port 112 under the influence of gravity, in some embodiments of this utility model, a cover member 300 covering the outer periphery of the connecting port 112 is provided inside the valve base 110. The gravity seal 200 is located inside the cover member 300, and the gravity seal 200 can move relative to the cover member 300 to open or close the connecting port 112. The side wall of the cover member 300 has at least one hollow hole 310. In this embodiment, the side wall of the cover member 300 has multiple hollow holes 310 circumferentially open, allowing air to flow through. By adopting the above structure, the cover 300 restricts the gravity seal 200 to the position of the connection port 112. The gravity seal 200 can move away from and open the connection port 112 in the vertical direction, or the gravity seal 200 can move closer to and close the connection port 112 in the vertical direction. However, the gravity seal 200 will not move away from the air intake channel 111. Therefore, when the gravity seal 200 is not subjected to other external forces, the gravity seal 200 will automatically move downward under the action of gravity to press against and close the connection port 112.
[0038] In some embodiments of this utility model, a connecting seat 140 is provided on the upper part of the valve base 110. The connecting seat 140 is located inside the receiving cavity 130. The air inlet channel 111 is opened in the middle of the connecting seat 140. The connecting port 112 is located on the top of the connecting seat 140. The cover member 300 is detachably installed on the upper part of the connecting seat 140. Therefore, the cover member 300 covers the connecting port 112 inside it. When the gravity seal 200 is placed inside the cover member 300, the gravity seal 200 can open or close the connecting port 112 by moving up and down along the cover member 300. By adopting the above structure, it is convenient to install the cover member 300 on the valve base 110.
[0039] Reference Figure 3 and Figure 8 To facilitate the connection between the cover member 300 and the connecting seat 140, in some embodiments of this utility model, one or more first snap-fit structures are provided between the connecting seat 140 and the cover member 300. The first snap-fit structure includes a first snap-fit groove 410 and a first snap-fit block 420 that can engage with each other. One of the first snap-fit groove 410 and the first snap-fit block 420 is provided in the connecting seat 140, and the other is provided in the cover member 300. Specifically, when the first snap-fit groove 410 is provided in the connecting seat 140, the first snap-fit block 420 is provided in the cover member 300, or when the first snap-fit groove 410 is provided in the cover member 300, the first snap-fit block 420 is provided in the connecting seat 140. The specific arrangement can be determined according to actual needs.
[0040] In this embodiment, the first snap-fit groove 410 is formed on the lower side wall of the cover member 300, and the first snap-fit block 420 is disposed on the upper outer wall of the connecting seat 140. Therefore, when the cover member 300 is installed on the upper part of the connecting seat 140, it is only necessary to sleeve the cover member 300 on the upper part of the connecting seat 140 and make the first snap-fit block 420 correspondingly embedded in the first snap-fit groove 410 to realize the connection between the cover member 300 and the connecting seat 140. The installation is simple and convenient.
[0041] To make the connection between the cover member 300 and the connecting seat 140 more secure, in some embodiments of this utility model, two sets of first snap-fit structures are provided between the connecting seat 140 and the cover member 300. The two sets of first snap-fit structures are respectively provided on opposite sides of the cover member 300. Therefore, when the cover member 300 is installed on the upper part of the connecting seat 140, the cover member 300 can be connected to the connecting seat 140 through the two sets of first snap-fit structures, thereby making the connection between the cover member 300 and the connecting seat 140 more reliable and less prone to loosening.
[0042] It should be noted that in the above embodiments, the cover 300 and the connecting seat 140 are engaged by the first snap-fit block 420 and the first snap-fit groove 410. In some embodiments of this utility model, the cover 300 can also be installed on the connecting seat 140 using other connection structures. For example, the upper outer peripheral wall of the connecting seat 140 is provided with an external thread, and the lower inner peripheral wall of the cover 300 is provided with an internal thread that matches the external thread of the connecting seat 140. During installation, it is only necessary to align the lower part of the cover 300 with the upper part of the connecting seat 140, and then screw the cover 300 relative to the connecting seat 140 to connect it. This allows the cover 300 to be threaded onto the connecting seat 140. When it is necessary to disassemble the cover 300, it is only necessary to screw the cover 300 in the opposite direction. The operation is simple and convenient.
[0043] Reference Figure 4 , Figure 5 and Figure 6 To prevent gas entering the receiving cavity 130 from the connecting port 112 from being directly ejected from the outlet channel 121, in some embodiments of this invention, the outlet channel 121 is located on the upper surface of the valve cover 120 away from the connecting port 112. A downwardly extending partition plate 122 is provided on the inner wall of the top of the valve cover 120, located between the outlet channel 121 and the connecting port 112. A gap is left between the lower part of the partition plate 122 and the bottom wall of the inner wall of the receiving cavity 130 for airflow. With this structure, after the high-pressure, high-temperature gas flows into the receiving cavity 130 from the connecting port 112, it is blocked by the partition plate 122. The high-pressure, high-temperature gas flows downward from the inner wall of the top of the valve cover 120, then passes through the gap between the lower part of the partition plate 122 and the bottom wall of the inner wall of the receiving cavity 130, and flows below the outlet channel 121. Afterward, the high-pressure, high-temperature gas moves upward and is discharged from the outlet channel 121. By adopting the above structure, the high-pressure and high-temperature gas flows in a curved manner inside the containment cavity 130, which helps to reduce the gas speed and prevents the high-pressure and high-temperature gas from entering the containment cavity 130 from the connecting port 112 and being sprayed directly out from the gas outlet 121. This helps to avoid the high-pressure and high-temperature gas being sprayed onto the human body and accidentally injuring people.
[0044] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In order to facilitate the installation of the valve cover 120 on the upper part of the valve base 110, in some embodiments of this utility model, one or more second snap-fit structures are provided between the valve base 110 and the valve cover 120. The second snap-fit structure includes a second snap-fit groove 430 and a second snap-fit block 440 that can be snapped together. When the second snap-fit groove 430 is provided on the outer wall of the valve base 110, the second snap-fit block 440 is provided on the inner wall of the valve cover 120, or when the second snap-fit groove 430 is provided on the inner wall of the valve cover 120, the second snap-fit block 440 is provided on the outer wall of the valve base 110.
[0045] In this embodiment, the second snap-fit groove 430 is formed on the lower part of the inner wall of the valve cover 120, and the second snap-fit block 440 is disposed on the upper part of the outer wall of the valve base 110. When the valve cover 120 is installed on the upper part of the valve base 110, it is only necessary to make the second snap-fit block 440 snap into the second snap-fit groove 430 accordingly, which is simple and convenient to operate.
[0046] To make the connection between the valve cover 120 and the valve base 110 more secure, in some embodiments of this utility model, two, three, or more sets of second snap-fit structures are provided between the valve cover 120 and the valve base 110. All the second snap-fit grooves 430 are evenly spaced on the lower part of the inner wall of the valve cover 120, and all the second snap-fit blocks 440 are evenly spaced on the upper part of the outer wall of the valve base 110. Therefore, when the valve cover 120 is installed on the upper part of the valve base 110, all the second snap-fit blocks 440 and all the second snap-fit grooves 430 are snapped together one by one, thereby making the connection between the valve cover 120 and the valve base 110 more reliable.
[0047] To prevent the second snap-fit block 440 of the second snap-fit structure from accidentally dislodging from the second snap-fit groove 430, in some embodiments of this utility model, a positioning structure is provided between the second snap-fit groove 430 and the second snap-fit block 440 in one set of second snap-fit structures. The positioning structure includes a positioning groove 510 and a positioning block 520 that cooperate to position each other. The positioning groove 510 is formed in the groove wall of the second snap-fit groove 430, and the positioning block 520 is disposed in the side wall of the second snap-fit block 440. Alternatively, the positioning groove 510 is disposed in the side wall of the second snap-fit block 440, and the positioning block 520 is disposed in the groove wall of the second snap-fit groove 430. By adopting the above structure, the second snap-fit block 440 is snapped in place. When the second snap-fit block 440 is inside the second snap-fit groove 430, the positioning block 520 is correspondingly embedded inside the positioning groove 510. At this time, the positioning block 520 and the positioning groove 510 are snap-fitted and positioned, so the second snap-fit block 440 can be locked inside the second snap-fit groove 430, effectively preventing the second snap-fit block 440 from accidentally coming out of the second snap-fit groove 430, making the connection of the second snap-fit structure more secure. When it is necessary to release the snap-fit between the second snap-fit block 440 and the second snap-fit groove 430, the user needs to apply force to the valve cover 120 and the valve base 110, so that the positioning block 520 comes out of the positioning groove 510, and then the second snap-fit block 440 can come out of the second snap-fit groove 430.
[0048] It should be noted that in the above embodiments, the valve cover 120 and the valve base 110 are engaged by the second snap-fit block 440 and the second snap-fit groove 430. However, in some embodiments of this utility model, other connection structures can be used between the valve cover 120 and the valve base 110. Specifically, the upper outer peripheral wall of the valve base 110 is provided with an external thread, and the lower inner peripheral wall of the valve cover 120 is provided with an internal thread that matches the external thread of the upper part of the valve base 110. During installation, it is only necessary to align the lower part of the valve cover 120 with the upper part of the valve base 110, and then the user can rotate the valve cover 120 relative to the valve base 110 to make the valve cover 120 threadedly connected to the upper part of the valve base 110. When it is necessary to remove the valve cover 120, the user only needs to rotate the valve cover 120 in the opposite direction to remove the valve cover 120 from the valve base 110. The operation is simple and convenient.
[0049] In order to allow the liquid accumulated inside the receiving cavity 130 to flow back into the rice cooker, in some embodiments of this utility model, the lower part of the gas valve base 110 is provided with a return hole 150 that communicates with the receiving cavity 130. By adopting the above structure, after the high temperature and high pressure steam flows into the receiving cavity 130 from the connecting port 112, liquid accumulates inside the receiving cavity 130 during the flow of the steam. The liquid can be discharged through the return hole 150 at the lower part of the gas valve base 110 and flow back into the rice cooker.
[0050] Furthermore, the lower part of the valve base 110 is provided with a mounting hole 160 located on one side of the return hole 150. A connecting post 170 is movably installed inside the mounting hole 160. The connecting post 170 is connected to a sealing element 180 that can open or block the return hole 150. The sealing element 180 is located below the return hole 150. Under the action of gravity, the sealing element 180 can drive the connecting post 170 to move downward relative to the valve base 110, and cause the sealing element 180 to move downward away from and open the return hole 150.
[0051] When the gas valve assembly of this embodiment is applied to the rice cooker, the rice cooker begins cooking. Initially, the gas pressure inside the rice cooker is low. Under the influence of gravity, the sealing member 180 moves the connecting column 170 downward relative to the gas valve base 110. The sealing member 180 moves downward away from the gas valve base 110 and opens the return hole 150. During the cooking process, the gas pressure inside the rice cooker continuously increases. When the pressure applied to the lower surface of the sealing member 180 exceeds the weight of the sealing member 180 and the connecting column 170, the gas pushes the sealing member 180, causing the connecting column 170 to move upward relative to the gas valve base 110, making the sealing member 180 fit tightly against the gas valve base 110. The return hole 150 is sealed. At this time, the high temperature and high pressure gas inside the rice cooker can only flow into the receiving cavity 130 from the air inlet channel 111 and then be discharged from the air outlet channel 121. During this process, liquid will accumulate inside the receiving cavity 130. When the rice cooker stops cooking and the pressure inside the rice cooker is less than the weight of the seal 180 and the connecting column 170, the seal 180 will move the connecting column 170 downward relative to the gas valve base 110 under the action of gravity. The seal 180 moves downward away from the gas valve base 110 and opens the return hole 150. At this time, the liquid accumulated in the receiving cavity 130 can flow back into the rice cooker from the return hole 150.
[0052] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5In some embodiments of this utility model, a decorative element 123 is detachably installed on the outer peripheral wall of the valve cover 120. In this embodiment, the decorative element 123 is a decorative ring sleeved on the outer peripheral wall of the valve cover 120. The decorative element 123 is fixed to the outer peripheral wall of the valve cover 120 by snap-fit.

[0054] Reference Figures 1 to 9 An electric rice cooker according to certain embodiments of the present invention includes an electric rice cooker lid 600, the electric rice cooker lid 600 being equipped with the aforementioned electric rice cooker gas valve assembly.
[0055] In this embodiment, the rice cooker employs the aforementioned rice cooker gas valve assembly. The rice cooker lid 600 covers the rice cooker body. In the initial state, the gravity seal 200 closes the connection port 112 of the air inlet channel 111 under the action of gravity. At this time, the rice cooker gas valve assembly is in a closed state and cannot release gas. During the heating and cooking process, the internal gas pressure of the rice cooker continuously increases. When the internal pressure of the rice cooker exceeds the set value of the rice cooker gas valve assembly, the thrust exerted by the gas inside the rice cooker on the gravity seal 200 exceeds the weight of the gravity seal 200 itself. The gas pushes the gravity seal 200 upward relative to the gas valve base 110, raising it and opening the connection. At port 112, the air inlet channel 111 of the rice cooker's gas valve assembly is open. Gas inside the rice cooker can flow from the air inlet channel 111 into the receiving cavity 130 of the gas valve body 100, and finally exit from the air outlet channel 121, achieving gas exhaust and pressure relief. When the pressure inside the rice cooker is less than the set value of the rice cooker's gas valve assembly, the thrust exerted by the gas inside the rice cooker on the gravity seal 200 is less than the weight of the gravity seal 200 itself. Under the action of gravity, the gravity seal 200 moves downward relative to the gas valve base 110 and closes the connecting port 112, thereby closing the rice cooker's gas valve assembly. The rice cooker's gas valve assembly no longer exhausts gas and relieves pressure, thus keeping the gas pressure inside the rice cooker stable and achieving the function of pressure maintenance. By adopting the above structure, the rice cooker's gas valve assembly only opens to exhaust gas when the pressure inside the rice cooker reaches the set value, which helps to solve the technical problem of the direct and large-scale exhaust of gas from the rice cooker affecting the cooking efficiency of the rice cooker.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
