Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a cooking utensil with a pot cover assembly. Background Art

[0002] The float valve is a component used for exhaust on cooking appliances (such as rice cookers, electric pressure cookers, etc.). The float valve includes a valve seat and a float. The float is installed in the installation channel of the valve seat and can float up and down relative to the valve seat. A sealing member is provided at the lower end of the float. When the float floats up, the sealing member abuts against the valve seat to block the exhaust channel, and exhaust cannot be performed at this time. When the float falls, the sealing member and the valve seat are separated from the seal, and the exhaust channel is opened.

[0003] The lower section of the float has a smaller diameter, extends into the installation channel, and can float up and down. The middle section of the float has a larger diameter, and forms a stopper with the valve seat, which limits the float downward and prevents it from sliding into the pot. At the same time, the seal is set at the lower end of the float, which can cooperate with the valve seat to limit the float upward. When installing the float, first pass the lower end of the float through the valve seat from top to bottom, and then fix the seal at the lower end of the float.

[0004] However, during use, the seal at the bottom of the float is prone to fall off, so that the float loses its upward limit. When the air pressure in the pot increases, the float will float upward under the action of the air pressure and fall off the valve seat. In addition, after the seal falls off, when the user removes or cleans the pot cover, for example, after turning the pot cover over, the float will also fall off under its own gravity, which not only causes inconvenience in use and requires frequent float installation, but also causes the original function of the float valve to be lost, affecting the normal use of the cooking appliance. Utility Model Content

[0005] The utility model provides a pot cover assembly and a cooking utensil, so as to solve the problem that after the sealing piece of the float falls off, the float is easy to fall off from the valve seat, thus affecting the use experience and the use function of the cooking utensil.

[0006] The technical solution adopted by the utility model is:

[0007] A pot cover assembly comprises a cover body and a float valve assembly arranged on the cover body, wherein the cover body is provided with an installation opening, the float valve assembly comprises a float seat, a float and a sealing member, the float seat has an installation channel, the sealing member is fixed to the lower end of the float, a limiting portion is arranged on the inner wall of the installation channel, a matching portion is arranged on the outer wall of the lower end of the float, the float can rotate relative to the float seat so that the matching portion and the limiting portion match to assemble the float in the installation channel, the float also comprises a guide section located above the matching portion, and the guide section can float up and down in the installation channel.

[0008] The pot cover assembly of the utility model also has the following additional technical features:

[0009] The limiting portion includes a first thread segment arranged along the axial direction of the installation channel, and the matching portion includes a second thread segment matched with the first thread segment.

[0010] The first thread segments are arranged at intervals along the circumference of the installation channel, and an avoidance groove is formed between two adjacent first thread segments.

[0011] The minor diameter of the first thread segment is D1, and the major diameter of the second thread segment is d, wherein D1<d.

[0012] The matching part includes a limiting protrusion arranged on the periphery of the float, and the limiting part includes a passing groove arranged corresponding to the limiting protrusion. The float can rotate relative to the float seat so that the limiting protrusion and the passing groove are aligned or misaligned.

[0013] The sealing element is sleeved on the outer periphery of the float to cover the matching portion.

[0014] The float also includes a matching section located below the guide section and a stop section located above the guide section. The matching portion is arranged on the matching section. The limiting portion forms a guide channel for the guide section to pass through. The outer diameter of the stop section and the maximum outer diameter of the matching section are both greater than the minimum diameter of the guide channel.

[0015] A limiting groove is arranged on the peripheral side of the float, and at least a partial area of ​​the sealing element is fixed in the limiting groove.

[0016] The float seat has a retaining rib extending downward, the retaining rib forms an accommodating space below the cover body, and the float is located in the accommodating space.

[0017] The utility model also discloses a cooking utensil, comprising a pot body with a cooking cavity and the pot cover assembly. The pot cover assembly can move relative to the pot body to open or cover the cooking cavity, and the lower end of the float extends into the cooking cavity.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the utility model, the installation channel inside the float seat is provided with a limiting portion, and the outer wall of the float is correspondingly provided with a matching portion. Only when the float rotates relative to the float seat and the limiting portion and the matching portion cooperate, can the float be installed and removed. That is to say, after the float is installed in place, the float cannot be removed from the float seat only by moving up and down (for example, only under the upward driving force of the airflow in the pot or the gravity of the float itself after the pot cover assembly is turned over), and the float remains in the installation channel. The float can only be removed by applying a rotating force to the float to rotate it relative to the float seat. In this way, the user can easily and quickly remove or install the float by himself, and only needs to rotate the float. It also reduces the risk of the float falling off the float seat due to accidental touch, saves the user the trouble of frequently installing the float, and ensures the normal operation of the float valve assembly.

[0020] 2. As a preferred embodiment of the utility model, the limiting portion includes a first thread segment arranged along the axial direction of the installation channel, and the matching portion includes a second thread segment matched with the first thread segment. By setting an internal thread segment in the installation channel of the float seat, and setting an external thread segment matched with the first thread segment on the outer wall of the float, the float and the float seat can be locked and unlocked by screwing. When installing the float, the second thread segment is rotated to pass through the first thread segment and is located below the first thread segment. When the float does not rotate and floats upward for a certain distance, the second thread segment is stopped by the inner thread of the first thread segment, so that the float cannot continue to float upward, forming an upward limit on the float to prevent the float from falling off. When disassembling the float, it is only necessary to rotate the float in the opposite direction of the installation screwing direction, so that the second thread segment can pass through the first thread segment upward to complete the unlocking of the float and the float seat. The thread matching method is simple and clear to operate, the user's learning cost is low, it is more convenient to use, and the user experience is better.

[0021] 3. As a preferred embodiment of the present invention, the matching portion includes a limiting protrusion arranged on the periphery of the float, and the limiting portion includes a passing groove arranged corresponding to the limiting protrusion, and the float can rotate relative to the float seat so that the limiting protrusion and the passing groove are aligned or misaligned. In this embodiment, the limiting protrusion is arranged on the periphery of the float so that a part of the lower end of the float is a non-circular structure, and the passing groove is correspondingly arranged inside the installation channel. Therefore, when the limiting protrusion and the passing groove are in a misaligned state, the float cannot slide upward from the installation channel. Only when the limiting protrusion and the passing groove are aligned up and down by rotating the float, the limiting protrusion can be smoothly passed through the passing groove to remove the float from the installation channel. When assembling and disassembling the float in this way, the float only needs to be rotated by a small angle to install and disassemble the float, which takes less time and has higher efficiency.

[0022] 4. As a preferred embodiment of the present invention, the seal is sleeved on the outer periphery of the float to cover the fitting part. When the seal has not fallen off, there is no need to use the limiting part and the fitting part to limit the float. Therefore, when the seal is assembled on the lower end of the float, the fitting part is covered. The shape of the fitting part is irregular, which can improve the installation stability of the seal, increase the friction between the seal and the fitting part, and reduce the probability of the seal falling off. In addition, the seal covers the fitting part, which can ensure the cleanliness of the fitting part and prevent the steam, food residues, etc. in the pot from adhering to the fitting part, affecting the coordination between the fitting part and the limiting part, and causing the problem of difficulty in disassembling the float.

[0023] 5. As a preferred embodiment of the present invention, the float seat has a retaining rib extending downward, and the retaining rib forms a containing space below the cover body, and the float is located in the containing space. The retaining rib forms a circumferential shielding for the portion of the lower end of the float extending into the pot body, so that the airflow in the pot can only enter the containing space from bottom to top to act on the float, thereby forming an upward thrust on the float, reducing the airflow blowing from one side of the float to the float, avoiding the lateral airflow from causing the float to rotate, and ensuring the stability of the float.

[0040] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0045] like Figure 1 , Figure 2 As shown, a pot cover assembly includes a cover body 1 and a float valve assembly 2 arranged on the cover body 1, the cover body 1 is provided with a mounting opening, the float valve assembly 2 includes a float seat 21, a float 22 and a sealing member 23, the float seat 21 has a mounting channel 211, the sealing member 23 is fixed to the lower end of the float 22, the inner wall of the mounting channel 211 is provided with a limiting portion, the outer wall of the lower end of the float 22 is provided with a matching portion, the float 22 can rotate relative to the float seat 21 so that the matching portion and the limiting portion match to assemble the float 22 in the mounting channel 211, the float 22 also includes a guide section 222 located above the matching portion, and the guide section 222 can float up and down in the mounting channel 211.

[0046] In the utility model, the installation channel 211 inside the float seat 21 is provided with a limiting portion, and the outer wall of the float 22 is correspondingly provided with a matching portion. Only when the float 22 rotates relative to the float seat 21 and the limiting portion and the matching portion cooperate, can the float 22 be installed and removed. That is to say, after the float 22 is installed in place, the float 22 cannot be removed from the float seat 21 only by moving up and down (for example, only under the upward driving force of the airflow in the pot or the gravity of the float 22 itself after the pot cover assembly is turned over), and the float 22 remains in the installation channel 211. Only by applying a rotating force to the float 22 to make it rotate relative to the float seat 21 can the float 22 be removed. In this way, it is relatively simple and quick for the user to actively remove or install the float 22, and only the float 22 needs to be rotated. The risk of the float 22 being accidentally touched and falling off the float seat 21 is also reduced, eliminating the trouble of the user needing to frequently install the float 22 , and ensuring the normal operation of the float valve assembly 2 .

[0047] In addition, after the float 22 is installed in place, the up and down floating of the float 22 can also realize the connection or sealing between the inside of the pot and the outside world. When the float 22 floats up to the lower end where the sealing member 23 abuts against the float seat 21, the environment inside the pot is sealed and isolated from the outside world. When the float 22 falls down to the point where the sealing member 23 is out of abutment with the float seat 21, the environment inside the pot is connected to the outside world.

[0048] It should be noted that the present invention does not limit the structure of the limiting portion and the matching portion, which includes but is not limited to the situations listed in the following embodiments:

[0049] Implementation method 1: In this implementation method, Figures 2 to 5 As shown, the limiting portion includes a first thread segment 212 arranged along the axial direction of the installation channel 211 , and the matching portion includes a second thread segment 221 matched with the first thread segment 212 .

[0050] By setting an internal thread section in the installation channel 211 of the float seat 21, and setting an external thread section that cooperates with the first thread section 212 on the outer wall of the float 22, the float 22 and the float seat 21 can be locked and unlocked by screwing. When installing the float 22, the float 22 is rotated to make the second thread section 221 rotate through the first thread section 212 and be located below the first thread section 212. When the float 22 floats upward for a certain distance without rotating, the second thread section 221 is stopped by the inner thread of the first thread section 212, so that the float 22 cannot continue to float upward, forming an upward limit for the float 22 to prevent the float 22 from falling off. When disassembling the float 22, it is only necessary to rotate the float 22 in the direction opposite to the installation screwing direction, so that the second thread section 221 can pass through the first thread section 212 upward, and the float 22 and the float seat 21 are unlocked. The threaded matching method is simple and clear to operate, the user's learning cost is low, the use is more convenient, and the use experience is better.

[0051] It should be noted that the present embodiment does not limit the lengths of the first thread segment 212 and the second thread segment 221. The lengths of the first thread segment 212 and the second thread segment 221 along the axial direction of the float 22 may be the same or different. Figure 2 As shown, the length of the second thread segment 221 is smaller than the length of the first thread segment 212 .

[0052] In a preferred embodiment of this embodiment, Figure 5 , Figure 6 As shown, the first thread segments 212 are arranged at intervals along the circumference of the installation channel 211 , and an avoidance groove 214 is formed between two adjacent first thread segments 212 .

[0053] When assembling the float 22, the second thread segment 221 of the float 22 first rotates through the first thread segment 212 of the float seat 21. After the second thread segment 221 passes through, a portion of the area above the second thread segment 221 can move up and down in the cavity at the avoidance groove 214 of the float seat 21. After assembly, the upper and lower ends of the float 22 are larger than the size of the cavity at the avoidance groove 214, so that the float 22 will not fall off from the top and bottom.

[0054] In addition, the avoidance groove 214 can also avoid the float 22, so that when the float 22 falls, the gas in the pot can not only be discharged from the inside of the float 22, but also can be exhausted through the gap between the float 22 and the avoidance groove 214, thereby improving the exhaust efficiency. The second thread segment 221 cooperates with the first thread segment 212 in a part of the circumferential area, and has a gap with the inner wall of the float seat 21 in a part of the area, which ensures the stability of the thread fit and reduces the resistance and sticking feeling of the float 22 during the rotation process, making the user's operation more labor-saving and convenient.

[0055] Specifically, when the float 22 is in the falling state, the environment in the pot is connected to the outside through the hole on the float 22 and the avoidance groove 214, and the gas in the pot can flow out from the hole of the float 22 and the avoidance groove 214. When the pressure in the pot is greater than the weight of the float 22, the float 22 floats up, and the sealing member 23 abuts against the bottom of the float seat 21 to play a sealing role.

[0056] When the pressure in the pot is normally increased, the part of the float 22 above the second thread segment 221 moves in the first thread segment 212. When the seal 23 abuts against the bottom surface of the float seat 21, the float 22 is sealed and stops moving. When the float 22 needs to be cleaned, the seal 23 is removed, and then the float 22 can be removed by rotating it in the opposite direction. If the seal 23 falls off during use, the float 22 will not fall off from the float seat 21 because of the second thread segment 221 at the lower end of the float 22. The float 22 can only be removed by rotating it.

[0057] Furthermore, if Figure 2 As shown, the minor diameter of the first thread segment 212 is D1, and the major diameter of the second thread segment 221 is d, wherein D1<d. That is, the minimum inner diameter of the first thread segment 212 in the float seat 21 is smaller than the maximum outer diameter of the second thread segment 221 at the lower end of the float 22. When the float 22 does not rotate, the thread of the second thread segment 221 can cooperate with the upper and lower stoppers of the thread of the first thread segment 212 to limit the float 22 upward.

[0058] Implementation method 2: In this implementation method, Figures 9 to 11 As shown, the matching portion includes a limiting protrusion 226 arranged on the peripheral side of the float 22, and the limiting portion includes a through groove 215 arranged corresponding to the limiting protrusion 226. The float 22 can rotate relative to the float seat 21 to make the limiting protrusion 226 and the through groove 215 aligned or misaligned.

[0059] In this embodiment, the limiting protrusion 226 is arranged around the float 22 so that the partial area of ​​the lower end of the float 22 is a non-circular structure, and the through groove 215 is correspondingly arranged inside the installation channel 211. Therefore, when the limiting protrusion 226 and the through groove 215 are in a misaligned state, the float 22 cannot slide upward from the installation channel 211. Only when the limiting protrusion 226 and the through groove 215 are rotated by the float 22 so that the limiting protrusion 226 and the through groove 215 correspond to each other up and down, the limiting protrusion 226 can smoothly pass through the through groove 215 and the float 22 can be taken out of the installation channel 211. When installing and removing the float 22 in this way, the float 22 can be installed and removed by rotating the float 22 at a small angle, which shortens the installation and removal time and improves the installation and removal efficiency.

[0060] like Fig.10 , Fig.11As shown, in one embodiment, four limiting protrusions 226 are arranged at intervals around the circumference of the float 22, and the float seat 21 is correspondingly provided with four passing grooves 215. When the four limiting protrusions 226 correspond to the passing grooves 215 one by one, the float 22 is unlocked and can be taken out from the float seat 21 from above. When the limiting protrusions 226 and the passing grooves 215 are misaligned up and down, the float 22 cannot be taken out from above. Of course, the number and shape of the limiting protrusions 226 and the limiting grooves can also be other styles, which are not limited here.

[0061] In a preferred embodiment, Figure 7 , Figure 8 As shown, the sealing member 23 is sleeved on the outer periphery of the float 22 to cover the matching portion.

[0062] When the seal 23 has not fallen off, when the float 22 floats to a certain height, the seal 23 can abut against the bottom of the float seat 21 to limit the float 22 upward, so there is no need to use the limiting part and the matching part to limit the float 22. Therefore, when the seal 23 is assembled on the lower end of the float 22, the matching part is covered. The shape of the matching part is irregular, which can improve the installation stability of the seal 23, increase the friction between the seal 23 and the matching part, and reduce the probability of the seal 23 falling off. In addition, the seal 23 covers the matching part, which can ensure the cleanliness of the matching part, avoid the steam, food residues, etc. in the pot from adhering to the matching part, affecting the matching between the matching part and the limiting part, and causing the problem of difficulty in disassembling the float 22. When the seal 23 falls off, the matching part is exposed, and forms a limit to the float 22 with the limiting part.

[0063] Preferably, if Figure 2 As shown, the float 22 has a matching section 224 located at the lower part of the guide section 222, and a stop section 223 located at the upper part of the guide section 222. The matching portion is arranged on the matching section 224, and the limiting portion encloses a guide channel 213 for the guide section 222 to pass through. The outer diameter of the stop section 223 and the maximum outer diameter of the matching section 224 are both larger than the minimum diameter of the guide channel 213.

[0064] The guide section 222 of the float 22 is located in the guide channel 213 surrounded by the limiting portion, so that the float 22 can float up and down. The maximum outer diameters of the stop section 223 above the guide section 222 and the matching section 224 below are both larger than the minimum diameter of the guide channel 213, so that the stop section 223 and the matching section 224 can stop the float seat 21 up and down, forming upper and lower limits for the float 22. Even if the seal 23 falls off, the float 22 cannot fall off up and down.

[0065] Specifically, the maximum outer diameter of the stop section 223 of the float 22>the minimum inner diameter of the guide channel 213>the maximum outer diameter of the guide section 222 of the float 22; the maximum outer diameter of the matching section 224 of the float 22>the minimum inner diameter of the guide channel 213>the maximum outer diameter of the guide section 222 of the float 22.

[0066] Preferably, the seal 23 is sleeved on the lower end of the float 22 to reduce the difficulty of installing the seal 23 and improve the assembly efficiency. Figure 7 , Figure 8 As shown, a limiting groove 225 is provided on the circumference of the float 22, and at least a part of the seal 23 is fixed in the limiting groove 225. The limiting groove 225 can form upper and lower stops for the seal 23, improve the stability of the installation of the seal 23, and reduce the probability of the seal 23 falling off from the float 22.

[0067] In a preferred embodiment, Fig.12 As shown, the float seat 21 has a retaining rib 216 extending downward, and the retaining rib 216 forms an accommodating space 217 below the cover body 1 , and the float 22 is located in the accommodating space 217 .

[0068] The retaining rib 216 forms a circumferential shielding for the portion of the lower end of the float 22 extending into the pot body, so that the airflow in the pot can only enter the accommodating space 217 from bottom to top to act on the float 22, thereby forming an upward thrust on the float 22, reducing the airflow blowing toward the float 22 from one side of the float 22, avoiding the lateral airflow from causing the float 22 to rotate, and ensuring the stability of the float 22.

[0069] The utility model also discloses a cooking utensil, comprising a pot body with a cooking cavity and the pot cover assembly. The pot cover assembly can move relative to the pot body to open or cover the cooking cavity, and the lower end of the float 22 extends into the cooking cavity.

[0070] It should be noted that the present invention does not limit the manner in which the pot cover assembly opens or closes the cooking cavity. In one embodiment, one end of the pot cover assembly is rotatably connected to the pot body, so that the pot cover assembly can be flipped around the connection to open or close the cooking cavity.

[0071] In another embodiment, the pot cover assembly is removably disposed on the pot body, so that the pot cover assembly can be removed from the pot body to open the cooker.

[0072] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0073] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0074] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
