Description

Technical Field

[0001] The present invention relates to a cooking appliance. Background Art

[0002] In existing cooking appliances, for example, in bottom-air intake gas cooking appliances, a liquid receiving tray is usually provided to hold overflowed liquid or dirt. A common liquid receiving tray usually has a part extending below the mixing chamber seat to prevent the liquid from directly falling through the pores in the middle of the liquid receiving tray. The mixing chamber seat is supported and installed on the sealed end table of the underlying base. There is usually a certain gap between the liquid receiving tray below the mixing chamber seat and the mixing chamber seat. For example, the cooking appliance disclosed in the published text of Chinese Patent Application CN215597268U includes a base (i.e., the mixing chamber seat), a base, and a liquid receiving tray.

[0003] It is difficult to control the distance between the existing mixing chamber seat and the liquid receiving tray. Even if the gap distance is set during design, due to the deformation of the liquid receiving tray during installation and other influences, the distance between the liquid receiving tray and the mixing chamber seat is likely to become too small or too large. When it is too small, interference will occur between the liquid receiving tray and the mixing chamber seat, directly supporting the mixing chamber seat. At this time, due to the lever effect, the contact surface between the mixing chamber seat and the sealed end table of the base is likely to be pried open, resulting in gas leakage. In some other cases, the gap distance between the liquid receiving tray and the mixing chamber seat is too large, which is not only unsightly but also prone to dirt accumulation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the gap distance between the liquid receiving tray and the mixing chamber seat after installation deviates greatly from the predetermined distance in the prior art, and to provide a cooking appliance.

[0005] The present invention solves the above technical problem through the following technical solutions:

[0006] A cooking appliance includes a base, a mixing chamber seat, and a liquid receiving tray. The inner edge of the liquid receiving tray extends below the mixing chamber seat. The base has a seat body and a sealed end table that is higher than the seat body. The bottom of the mixing chamber seat cooperates with the sealed end table. A flexible gasket is provided on the seat body. The radial outer side of the gasket has a contact end face and surrounds the outside of the sealed end table. The liquid receiving tray is fixed on the seat body. The inside of the liquid receiving tray is hollowed out to accommodate the sealed end table. The inner edge of the liquid receiving tray extends towards the sealed end table and presses against the contact end face to generate a pressing force.

[0007] In this solution, the inner edge of the liquid receiving tray contacts the contact end face of the gasket, so that the inner edge of the liquid receiving tray is pressed against the gasket to form a seal, preventing overflow liquid from entering the interior of the gas stove. At this time, the inner edge of the liquid receiving tray is closest to the center, so the lever arm of the moment generated at the inner edge of the liquid receiving tray is the smallest. Therefore, by reducing the lever arm, the deformation effect of the moment generated by the reaction force during installation on the liquid receiving tray can be significantly reduced. Compared with existing stoves, it can reduce more deformation effects caused by installation, ensuring that the gap between the liquid receiving tray and the mixing chamber seat after installation can be maintained within a predetermined appropriate gap range. In addition, after the liquid receiving tray and the base are fixed with screws, they are subjected to a certain extrusion force. After high-temperature cooking ends, abnormal noises are likely to occur during the cooling process, bringing a certain psychological burden to the user and affecting the cooking experience. Separating the liquid receiving tray and the base with a gasket can also eliminate the abnormal noises.

[0008] Preferably, the liquid receiving tray and the seat body are fixed through fasteners. The seat body is provided with first mounting holes for connecting the seat body and the fasteners of the liquid receiving tray; and / or the mixing chamber seat and the sealing end table are fixed through fasteners, and the sealing end table is provided with second mounting holes for connecting the mixing chamber seat and the fasteners of the sealing end table. Using fasteners can facilitate installation and replacement.

[0009] Preferably, the periphery of the first mounting hole has an upwardly protruding mounting plane, and the bottom of the liquid receiving tray contacts the mounting plane. The mounting plane is higher than the surface of the seat body. When the liquid receiving tray is pressed and fixed by the fasteners, there is space for the deformation and downward movement of the liquid receiving tray, which can reduce the contact between the liquid receiving tray and the surface of the seat body, reduce the reverse moment, thereby reducing the deformation of the liquid receiving tray and the influence on the gap between the mixing chamber seat and the liquid receiving tray.

[0010] Preferably, several of the first mounting holes and / or several of the second mounting holes are arranged on the same circumference. The co-centered arrangement of the first mounting holes can make the force on the circumference of the liquid receiving tray uniform, and the deformation amount of the entire circumference of the liquid receiving tray after being subjected to the downward pressure is uniform, so that the gap between the entire circumference of the liquid receiving tray and the mixing chamber seat is more uniform. The co-centered arrangement of the second mounting holes can make the axial force optimal when the end face of the mixing chamber seat and the sealing end table of the base are sealed, thereby improving the sealing performance between the mixing chamber seat and the base and reducing the risk of air leakage.

[0011] Preferably, the liquid holding tray has a sunken portion and a shoulder portion surrounding the sunken portion. The inner edge of the liquid holding tray extends along the sealing end platform, and the sunken portion is divided into several installation sub-regions arranged in the circumferential direction. Each installation sub-region is provided with a third installation hole, and the third installation hole cooperates with the first installation hole to fix the fastener. The installation sub-regions can make the third installation holes more dispersed and uniform, so that the force on the circumference of the liquid holding tray is uniform, avoiding serious local deformation caused by the concentrated fasteners. Thus, the gap between the entire circumference of the liquid holding tray and the mixing chamber seat is more uniform. At the same time, the installation sub-regions can be engaged with the sealing end platform before installation to avoid circumferential rotation, so as to align the third installation hole and the first installation hole at the edge, facilitating the installation of the fastener. In addition, the fastener located in the sunken portion is closer to the inner edge of the liquid holding tray, which can inhibit the radial outward transmission of the deformation caused by the moment at the inner edge. Combining with the concave-convex shape between the sunken portion and the shoulder portion, the influence of the deformation on the shoulder portion can be further inhibited.

[0012] Preferably, the liquid holding tray has a sunken portion and a shoulder portion surrounding the sunken portion. A part of the shoulder portion is located in the lower region of the mixing chamber seat and is arranged with a gap from the mixing chamber seat. The sunken portion is located in the lower region of the mixing chamber seat. Among them, the height of the sealing end platform is higher than the height of the shoulder portion, and the height of the gasket is higher than the height of the shoulder portion. The sunken portion can form a curved cross-sectional shape with the shoulder portion. On the one hand, it improves the strength of the liquid holding tray, and on the other hand, it can also maintain a proper distance from the mixing chamber seat while ensuring fit with the seat body. The sealing end platform higher than the shoulder portion of the sunken portion and the shoulder portion can prevent liquid from entering when the seal fails. The height setting of the gasket ensures that even when it is located in the sunken portion, it can seal and block the liquid flowing in at the shoulder portion, thus ensuring the seal.

[0013] Preferably, the outer contour of the sealing end platform has a concave-convex shape in the radial direction. The convex portion of the sealing end platform extends to the junction of the sunken portion and the shoulder portion, and the concave portion of the sealing end platform contracts radially inward to accommodate the sunken portion. The irregular-shaped sealing end platform can limit the liquid holding tray, facilitating alignment and installation.

[0014] Preferably, the gasket extends along the outside of the sealing end platform and surrounds the sealing end platform. Among them, an interval region for accommodating the ignition needle and / or thermocouple is formed between the gasket and the concave portion. The ignition needle and / or thermocouple in the interval region can be sealed and protected to avoid being affected by the liquid.

[0015] Preferably, a sealing rib that protrudes upward is formed on the liquid storage tray or the gasket. The sealing rib is disposed on the radially outer side of the contact end surface near the position of the spacing area, and a closed sealing area is formed between the sealing rib and the contact end surface. The sealing rib can achieve an additional layer of sealing to ensure the safety of the ignition needle and / or the thermocouple.

[0016] Preferably, the edge of the shoulder portion is provided with an arc surface, and the projection of the outer diameter of the mixing chamber seat is located above the midpoint of the arc surface. Thus, when visually observing the gap between the mixing chamber seat and the shoulder portion of the liquid storage tray in the horizontal direction, the gap will be relatively small and the appearance will be more beautiful. At this time, the maximum gap between the lowermost end of the mixing chamber seat and the liquid storage tray in the vertical direction increases significantly compared to the gap observed horizontally, thereby ensuring a certain gap distance to prevent interference while maintaining the beauty.

[0017] Preferably, the gasket includes a cover body portion connected to the contact end surface, and the cover body portion covers the seat body; and / or the inner side of the contact end surface fits against the side surface of the sealing end platform to achieve the positioning of the gasket.

[0018] Preferably, the liquid storage tray and the base are made of metal materials.

[0019] Preferably, the cross-sectional shape of the contact end surface is an overall inclined straight line, curve, or a combination of a straight line and a curve.

[0020] The positive and progressive effects of the present invention are as follows: The present invention can significantly reduce the deformation influence of the torque generated by the reaction force during installation on the liquid storage tray. It ensures that the gap between the liquid storage tray and the mixing chamber seat after installation can be maintained within a predetermined appropriate gap range.

[0059] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments accordingly.

[0060] As Figures 1 - 11 shown, this embodiment discloses a cooking appliance. As Figures 2 - 5 shown, the cooking appliance of this embodiment includes a base 300, a gas mixing chamber base 200, and a liquid receiving tray 100. The inner edge 130 of the liquid receiving tray 100 extends below the gas mixing chamber base 200. The base 300 has a base body 320 and a sealing end platform 310 that is higher than the base body 320. The bottom of the gas mixing chamber base 200 is fitted with the sealing end platform 310. A flexible gasket 400 is arranged on the base body 320. The gasket 400 has a contact end face 410 radially outward and surrounds the outside of the sealing end platform 310. The liquid receiving tray 100 is fixed on the base body 320. The inside of the liquid receiving tray 100 is hollowed out to accommodate the sealing end platform 310. The inner edge 130 of the liquid receiving tray 100 extends towards the sealing end platform 310 and is pressed against the contact end face 410 to generate a pressing force.

[0061] The material of the gasket 400 in this embodiment can be various known flexible materials suitable for sealing, such as rubber materials, etc. The material and shape of the liquid receiving tray 100 in this embodiment can be known available materials and shapes. The shape can be, for example, circular or square, and the material can be, for example, a metal material, etc. The gas mixing chamber base 200 and the base 300 can be known adapted shapes and structures.

[0062] In this embodiment, the inner edge 130 of the liquid holding tray 100 contacts the contact end face 410 of the gasket 400, so that the inner edge 130 of the liquid holding tray 100 and the gasket 400 are squeezed to form a seal, preventing overflow liquid from entering the interior of the gas stove. At this time, the inner edge 130 of the liquid holding tray 100 is closest to the center, so the lever arm of the moment generated at the inner edge 130 of the liquid holding tray 100 is the smallest. Therefore, by reducing the lever arm, the deformation effect of the moment generated by the reaction force during installation on the liquid holding tray 100 can be significantly reduced. Compared with the existing stoves, it can reduce more deformation effects caused by installation, ensuring that the gap between the liquid holding tray 100 and the mixing chamber seat 200 after installation can be maintained within a predetermined appropriate gap range. In addition, after the liquid holding tray 100 and the base 300 are fixed with screws, they are subjected to a certain extrusion force. After high-temperature cooking ends, abnormal noises are likely to occur during the cooling process, bringing a certain psychological burden to the user and affecting the cooking experience. Separating the liquid holding tray 100 and the base 300 with the gasket 400 can also eliminate the abnormal noises.

[0063] As Figures 1 - 3 shown, the sealing end table 310 in this embodiment is butted against the bottom of the mixing chamber seat 200. After the mixing chamber seat 200 and the base 300 are fitted, the space inside the mixing chamber seat 200 and the space inside the base 300 are joined together to form an internal mixing space. The outer ring burner cap 510 and the inner ring burner cap 520 are connected to the mixing chamber seat 200.

[0064] As Figures 3 - 5 shown, in a preferred embodiment, the liquid holding tray 100 and the seat body 320 are fixed by fasteners (not shown in the figure). The seat body 320 is provided with a first mounting hole 340 for connecting the fasteners of the seat body 320 and the liquid holding tray 100. As Figures 3 - 5 shown, in a preferred embodiment, the mixing chamber seat 200 and the sealing end table 310 are fixed by fasteners. The sealing end table 310 is provided with a second mounting hole 330 for connecting the fasteners of the mixing chamber seat 200 and the sealing end table 310. The use of fasteners facilitates installation and replacement.

[0065] In other embodiments, other fixing methods can also be used to fix the liquid holding tray 100 and the seat body 320, and other fixing methods can also be used to fix the mixing chamber seat 200 and the sealing end table 310. The fasteners can be known fasteners such as bolts and screws that are convenient for disassembly and replacement. Of course, they can also be structures such as rivets. In some embodiments, the second mounting hole 330 can also be provided on the seat body 320, and the cooperation between the sealing end table 310 and the mixing chamber seat 200 is realized through the connection between the seat body 320 and the mixing chamber seat 200.

[0066] As Figure 7As shown, in a further preferred embodiment, the periphery of the first mounting hole 340 has an upwardly protruding mounting plane 341, and the bottom of the liquid receiving tray 100 contacts the mounting plane 341. The mounting plane 341 is higher than the surface of the seat body 320. When the liquid receiving tray 100 is pressed and fixed by the fastener, there is space for the downward deformation of the liquid receiving tray 100, which can reduce the contact between the liquid receiving tray 100 and the surface of the seat body 320, reduce the reverse torque, thereby reducing the deformation of the liquid receiving tray 100 and the influence on the gap between the gas mixing chamber seat 200 and the liquid receiving tray 100. The mounting plane 341 can further be set to a circular shape or other shapes. In other embodiments, the mounting plane 341 can also be flush with the seat body 320. This setting will reduce the downward deformation space of the liquid receiving tray 100, but with the setting of the gasket 400, it still has less deformation compared to other existing cooktops. In some other embodiments, the mounting plane 341 can also be not provided, but a protruding plane can be provided in the corresponding area below the liquid receiving tray 100, thereby allowing space below other parts of the liquid receiving tray 100 to reduce the reverse torque. The mounting plane 341 can also be set to other shapes, such as feet, bump shapes, etc.

[0067] As Figure 7 shown, in a further preferred embodiment, several first mounting holes 340 and several second mounting holes 330 of this embodiment are arranged on the same circumference. The co - concentric setting of the first mounting holes 340 can make the force on the circumference of the liquid receiving tray 100 uniform, and the deformation amount of the entire circumference of the liquid receiving tray 100 after being subjected to the downward pressure is uniform, so that the gap between the entire circumference of the liquid receiving tray 100 and the gas mixing chamber seat 200 is more uniform. The co - concentric setting of the second mounting holes 330 can optimize the axial force when the end face of the sealing end table 310 of the gas mixing chamber seat 200 and the base 300 are sealed, thereby improving the sealing performance between the gas mixing chamber seat 200 and the base 300 and reducing the risk of air leakage. In some other embodiments, several first mounting holes 340 can be on the same circumference, while one or more of the several second mounting holes 330 are not on the same circumference. It can also be that several second mounting holes 330 are on the same circumference, while one or more of the several first mounting holes 340 are not on the same circumference. It can also be that one or more of the several first mounting holes 340 and the second mounting holes 330 are on the same circumference, and some others are not on the same circumference. In some other embodiments, the first mounting holes 340 and the second mounting holes 330 can also be arranged in various suitable arrangements.

[0068] As Figure 5 and Figure 6As shown, in a preferred embodiment, the liquid storage tray 100 has a sunken portion 110 and a shoulder portion 120 surrounding the sunken portion 110. The inner edge 130 of the liquid storage tray 100 extends along the sealing end platform 310, and the sunken portion 110 is divided into several installation sub-regions 111 arranged in the circumferential direction. Each installation sub-region 111 is provided with a third installation hole 140, and the third installation hole 140 cooperates with the first installation hole 340 to fix the fastener. The installation sub-regions 111 can make the third installation holes 140 more dispersed and uniform, so that the force on the circumference of the liquid storage tray 100 is uniform, avoiding serious local deformation caused by the concentrated fasteners. Thus, the gap between the entire circumference of the liquid storage tray 100 and the gas mixing chamber seat 200 is more uniform. At the same time, the installation sub-regions 111 can be engaged with the sealing end platform 310 before installation to avoid circumferential rotation, so as to align the third installation hole 140 and the first installation hole 340 at the edge, facilitating the installation of the fastener. In addition, the fasteners located in the sunken portion 110 are closer to the inner edge 130 of the liquid storage tray 100, which can suppress the radial outward transmission of the deformation caused by the moment of the inner edge 130. Combining the concave-convex shape between the sunken portion 110 and the shoulder portion 120 can further suppress the influence of the deformation on the shoulder portion 120. In other embodiments, the cross-sectional shape of the liquid storage tray 100 can also be other suitable cross-sectional shapes, such as a cross-sectional shape with multiple concavities and convexities in different regions. The third installation hole 140 is arranged to match the distribution of the first installation hole 340.

[0069] In the embodiments as Figure 5 and Figure 6 shown, the installation sub-regions 111 are divided into multiple non-connected regions. In other embodiments, the installation sub-regions 111 can also be connected to each other. The distribution of the installation sub-regions 111 can be avoided and evenly distributed according to the shape of the sealing end platform 310, and the connection relationship between the installation sub-regions 111 can also depend on the shape of the sealing end platform 310.

[0070] As Figure 5 and Figure 6As shown, in a preferred embodiment, the liquid holding tray 100 has a sunken portion 110 and a shoulder portion 120 surrounding the sunken portion 110. A part of the shoulder portion 120 is located in the lower region of the air mixing chamber seat 200 and is provided with a gap from the air mixing chamber seat 200. The sunken portion 110 is located in the lower region of the air mixing chamber seat 200. Among them, the height of the sealing end platform 310 is higher than that of the shoulder portion 120, and the height of the gasket 400 is higher than that of the shoulder portion 120. The sunken sunken portion 110 and the shoulder portion 120 can form a curved cross-sectional shape, which can improve the strength of the liquid holding tray 100 on the one hand and maintain an appropriate distance from the air mixing chamber seat 200 while ensuring the fitting of the seat body 320 on the other hand. The sealing end platform 310, which is higher than the shoulder portion 120 of the sunken portion 110 and the shoulder portion 120, can prevent liquid from entering when the seal fails. The height setting of the gasket 400 ensures that even if it is located in the sunken portion 110, it can seal and block the liquid flowing in at the shoulder portion 120, thereby ensuring the seal.

[0071] As Figure 5 and Figure 6 shown, in a preferred embodiment, the outer contour of the sealing end platform 310 has a concave-convex shape in the radial direction. The outer convex portion 311 of the sealing end platform 310 extends to the junction of the sunken portion 110 and the shoulder portion 120, and the inner concave portion 312 of the sealing end platform 310 contracts radially inward to accommodate the sunken portion 110. The irregular-shaped sealing end platform 310 can limit the liquid holding tray 100, facilitating alignment and installation. In other embodiments, the sealing end platform 310 can also be various other suitable outer contour shapes, and the inside of the liquid holding tray 100 is adapted to be hollowed out to accommodate the shape of the sealing end platform 310. The shape of the sunken portion 110 is matched according to the shape of the sealing end platform 310. In some other embodiments, the sealing end platform 310 can also be a regular shape, such as a circular shape. Some protrusions or grooves can be provided on the outer wall surface of the sealing end platform with these regular shapes to be adapted to the corresponding grooves or protrusions provided on the inner side edge 130 of the liquid holding tray 100, forming a restriction on the circumferential rotation of the liquid holding tray 100. In still other embodiments, the shape of the hollowed-out area in the middle of the liquid holding tray 100 may not be adapted to the shape of the sealing end platform 310, that is, the inner side edge 130 is a regular shape and the outer contour of the sealing end platform 310 is an irregular shape.

[0072] As Figures 5 - 8As shown, in a preferred embodiment, the gasket 400 extends along the outer side of the sealing end platform 310 and surrounds the sealing end platform 310. An interval region 350 for accommodating the ignition pin 610 and / or the thermocouple 620 is formed between the gasket 400 and the concave portion 312. The ignition pin 610 and / or the thermocouple 620 in the interval region 350 can be hermetically protected from the influence of liquid. In the present embodiment, the portion of the gasket 400 near the interval region 350 does not closely adhere to the contour of the sealing end platform 310, while other portions of the gasket 400 closely adhere to the outer contour of the sealing end platform 310. In some other embodiments, the gasket 400 may also not closely adhere to the outer contour of the sealing end platform 310 at other positions.

[0073] As Figures 5 - 8 shown, in a preferred embodiment, a sealing rib 430 protruding upward is formed on the liquid holding tray 100 or the gasket 400. The sealing rib 430 is disposed radially outward of the contact end face 410 near the interval region 350, and a closed sealing region 440 is formed between the sealing rib 430 and the contact end face 410. The sealing rib 430 can achieve an additional level of sealing to ensure the safety of the ignition pin 610 and / or the thermocouple 620. In Figure 8 the embodiment shown, due to the presence of the cover body portion 420, the sealing rib 430 is disposed on the gasket 400. In other embodiments, the gasket 400 may not be provided with the cover body portion 420, thereby exposing the surface of the liquid holding tray 100, and the sealing rib 430 can directly protrude on the surface of the liquid holding tray 100 to form a second layer of sealing.

[0074] As Figures 5 - 10 shown, in a preferred embodiment, an arc surface 150 is provided at the edge of the shoulder portion 120. The projection of the outer diameter of the mixing chamber seat 200 is located above the midpoint of the arc surface 150. Thus, when visually observing the gap between the mixing chamber seat 200 and the shoulder portion 120 of the liquid holding tray 100 in the horizontal direction, the gap will be relatively small and the appearance will be more beautiful. At this time, the maximum gap between the lowermost end of the mixing chamber seat 200 and the liquid holding tray 100 in the vertical direction increases significantly compared to the gap observed horizontally, thereby ensuring a certain gap distance to prevent interference while maintaining the beauty.

[0075] As Figure 8 and Figure 10 shown, in a preferred embodiment, the gasket 400 includes a cover body portion 420 connected to the contact end face 410, and the cover body portion 420 covers the seat body 320. In as Figure 11 shown in other embodiments, the inner side of the contact end face 410 is attached to the side surface of the sealing end platform 310 to position the gasket 400. Specifically, in Figure 11In the illustrated embodiment, the inner side of the contact end face 410 is fitted by the sealing end platform 310, and the contact end face 410 is pressed by the liquid holding tray 100. Thus, under the limit on both sides, the initial limit of the gasket 400 relative to the base 300 can be achieved without setting the cover portion 420.

[0076] In a preferred embodiment, the materials of the liquid holding tray 100 and the base 300 are metal materials. In other embodiments, the materials of the liquid holding tray 100 and the base 300 can be other materials. After using metal liquid holding tray 100 and base 300, the abnormal noise generated by the thermal expansion and contraction deformation between metals during the heating and cooling process of the stove is eliminated. After the metal liquid holding tray 100 and the metal base 300 are fixed, they are subjected to a certain extrusion force. After the high-temperature cooking ends, abnormal noise is likely to occur during the cooling process, bringing a certain psychological burden to the user and affecting the cooking experience. By separating the inner edge 130 of the liquid holding tray 100 from the base 300 through the gasket 400, the deformation can be absorbed, thereby eliminating the abnormal noise.

[0077] As Figures 1 - 11 shown, in a preferred embodiment, the cross-sectional shape of the contact end face 410 is a straight line that is overall inclined. In other embodiments, the shape of the contact end face 410 can also be a curve or a combination of a straight line and a curve.

[0078] The present invention can significantly reduce the influence of the moment generated by the reaction force during installation on the deformation of the liquid holding tray 100. It ensures that the gap between the liquid holding tray 100 and the mixing chamber seat 200 after installation can be maintained within a predetermined and appropriate gap range.
