Description

Technical Field

[0001] This invention relates to an electric cooking machine capable of separating the inner pot lid. Background Technology

[0002] An electric cooking appliance includes a main body with an inner pot for holding food and a lid covering the main body.

[0003] The lid is equipped with an inner pot lid to cover the upper part of the inner pot. Food is cooked with the inner pot lid covering the upper part of the inner pot; therefore, for hygiene and cleaning, the inner pot lid is designed to be detachable from the lid for separation and cleaning.

[0004] As a prior art presenting the disassembly and assembly structure of the inner pot lid, Korean Patent No. 10-1693341 is disclosed.

[0005] In the prior art, a single-contact support device is presented, which includes: a support bracket attached to one side of a control panel; a stop that ejects along the radial direction of the support bracket to restrict the edge of the through hole of the inner pot lid; and a housing attached to the support bracket and retracting the stop therein to release the restriction of the through hole when pressurized.

[0006] However, existing single-contact support devices are integrated with the lid, making them difficult to separate and clean. Furthermore, the stop only secures the inner lid in a straight line, resulting in reduced stability and potential for the inner lid to shift or become misaligned. Additionally, the operating direction (horizontal) of the stop differs from the pressure direction (vertical) of the outer casing used to house it, potentially causing wear due to friction between the two components and preventing the inner lid from separating properly due to the constraint between them. Summary of the Invention

[0007] The present invention is proposed to solve the above-mentioned problems, and its purpose is to provide an electric cooking machine that can easily separate and clean the single-contact support device.

[0008] The electric cooking appliance of the present invention for achieving the above-mentioned objectives includes: a main body having an inner pot for containing food inside; a lid attached to the upper part of the main body for opening and closing; a fixing plate disposed on the lower surface of the lid and having a through hole for steam flow of the inner pot; an inner pot lid disposed on the lower part of the fixing plate and covering the upper part of the inner pot, and having a through hole; and a single-contact support device for detachably attaching the inner pot lid to the lid, wherein the single-contact support device includes: a fixed... A fixing component is attached to the lower part of the fixing plate; a snap-fit ​​component is inserted into the through hole and snaps into the fixing component; an elastic component applies an elastic force to the snap-fit ​​component to maintain the snap-fit ​​state between the fixing component and the snap-fit ​​component; and a bracket cover is integrally and rotatably equipped with the snap-fit ​​component while attached to it, and the snap-fit ​​state between the fixing component and the snap-fit ​​component is released by a rotational force resisting the elastic force of the elastic component, so that the inner pot lid can be separated from the lid.

[0009] According to the present invention, the single-contact support device can be easily separated and cleaned.

[0010] Furthermore, the inner pot lid can be easily separated from the main lid simply by rotating the support cover.

[0011] Furthermore, the locking parts of the fixing components and the locking components are arranged radially around the circumference, which can improve the stability of the fixing and prevent the inner pot lid from flowing or becoming eccentric.

[0012] Furthermore, the engagement between the fixing component and the snap-fit ​​component is achieved by rotation, which minimizes wear caused by friction between the two components and significantly reduces the possibility of the inner lid not separating due to the constraint between the two components.

[0036] Explanation of reference numerals in the attached figures Detailed Implementation

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] <First Embodiment>

[0039] Reference Figures 1 to 8 The configuration of the electric cooking machine according to the first embodiment of the present invention will be described below. Hereinafter, when indicating direction, ... Figure 4 Based on this, the side where the reference numeral "10" is located is defined as the upper part, and the side where the reference numeral "140" is located is defined as the lower part.

[0040] The electric cooking appliance according to the first embodiment includes a main body (not shown), a lid 10, a fixing plate 30, an inner pot lid 50, and a single-contact support device composed of a fixing member 110, a snap-fit ​​member 130, an elastic member 140, and a support cover 150.

[0041] The main body is equipped with an inner pot (not shown) for holding food.

[0042] The cover 10 is attached to the upper part of the main body and rotates around the hinge part 11 on one side to open and close the main body.

[0043] The fixing plate 30 is provided on the lower surface of the cover 10 and has a connecting hole 32 for the flow of steam into the inner pot. The connecting hole 32 is equipped with a pressure balancing valve, a solenoid valve, and other pressure-responsive operation units that operate to discharge steam according to the pressure level inside the inner pot.

[0044] In the fixing plate 30, the fixing plate fixing part 31 for fixing the fixing component 110 is provided on one side of the communicating hole 32.

[0045] A fixing member insertion space 31a with a concave shape is formed on the lower surface of the fixing plate fixing part 31, and a fastening hole 31b communicating with the fixing member insertion space 31a and penetrating the fixing plate fixing part 31 vertically with a smaller diameter is formed on the upper part of the fixing member insertion space 31a. The fixing member insertion space 31a is for the upper part of the fixing member 110 to be inserted.

[0046] A guide plate 20 made of a corrosion-resistant material such as stainless steel is provided at the lower part of the fixing plate 30. The guide plate 20 is configured to cover the lower surface of the fixing plate 30 and is disposed between the fixing part 31 and the fixing member 110.

[0047] A steam discharge hole 21 is formed in the portion of the guide plate 20 corresponding to the connecting hole 32, and the steam inside the inner pot flows to the pressure corresponding operation unit through the steam discharge hole 21 and the connecting hole 32.

[0048] The inner pot lid 50 is detachably attached to the lower part of the fixing plate 30 and is configured to cover the upper part of the inner pot. A through hole 51 is formed on one side of the inner pot lid 50, and a plurality of flow holes 52 are formed around the outer side of the through hole 51 to allow steam to flow through the inner pot.

[0049] An inner pot lid fixing end 53 is formed around the through hole 51, protruding downward from the edge of the through hole 51.

[0050] The inner pot lid fixing end 53 protrudes downward from the edge of the through hole 51 in a generally quadrilateral plate shape, and a recessed groove-shaped fixing end groove 53b is formed on the upper side, and a protruding fixing end snap-fit ​​part 53a is formed at the lower part of the fixing end groove 53b.

[0051] The inner pot lid fixing end 53 may have multiple portions formed around the edge of the through hole 51. More preferably, the inner pot lid fixing end 53 may be composed of multiple portions (i.e., at least three) arranged radially.

[0052] The first end 143, which is one end of the elastic member 140, is elastically supported by the fixing end snap-fit ​​portion 53a of one of the plurality of inner pot lid fixing ends 53.

[0053] The single-contact support device is as follows: the inner pot lid 50 is joined to the lid 10 by pushing the inner pot lid 50 in the direction of the lid 10, and the inner pot lid 50 is disengaged from the lid 10 by rotating the support cover 150, thereby enabling the inner pot lid 50 to be separated from the lid 10.

[0054] The fixing component 110 is attached to the lower part of the fixing plate 30, and by engaging with the snap-fit ​​component 130, the inner pot lid 50, which is attached to the snap-fit ​​component 130, the elastic component 140 and the bracket cover 150, can remain attached to the lower surface of the lid 10.

[0055] The fixing component 110 is composed of a cylindrical fixing component body 111, a fixing component snap-fit ​​portion 112 protruding outward from the side of the fixing component body 111, and a fixing component fastening portion 113 protruding upward in a cylindrical shape from the upper surface of the fixing component body 111.

[0056] The fixing component snap-fit ​​portion 112 can be formed into a trapezoidal shape with a wider upper part and a narrower lower part, and one side can be formed with an inclined surface (first inclined surface) 112a in a manner that is inclined along the outer periphery.

[0057] The fixing component snap-fit ​​portion 112 may be formed in multiple portions around the outer side of the fixing component body 111. More preferably, the fixing component snap-fit ​​portion 112 may be composed of multiple portions arranged radially (i.e., at least three).

[0058] A downwardly recessed fastening groove 113a is formed at the center of the upper surface of the fastening part 113 of the fixing member. The fastening part 113 of the fixing member is configured in a shape that allows it to be inserted into the fastening insertion space 31a of the fixing member. When the fastening part 113 of the fixing member is inserted into the fastening insertion space 31a of the fixing member, the fastening member (not shown) passes through the fastening hole 31b and is fastened to the fastening groove 113a, thereby fixing the fixing member 110 to the fixing plate 30.

[0059] The fastening part 113 of the fixing component is coaxially formed with a diameter smaller than that of the main body 111 of the fixing component. The upper edge 111a of the main body 111 of the fixing component is formed with a shape that protrudes upwards from the upper surface of the central part of the main body 111. A sealing insertion groove 114 is formed between the outer side of the fastening part 113 of the fixing component and the inner side of the upper end of the main body 111 of the fixing component.

[0060] The sealing insertion groove 114 is for the insertion of the ring-shaped upper sealing member 120. The upper sealing member 120 is used to maintain an airtight seal between the fixing member 110 and the bottom surface of the guide plate 20 at the lower part of the covering fixing plate fixing part 31.

[0061] When the inner pot lid 50 is attached to the lid 10, the snap-fit ​​component 130 holds the inner pot lid 50 attached to the lid 10 by snapping with the fixing component 110 attached to the lid 10.

[0062] The snap-fit ​​component 130 includes: a snap-fit ​​component body 131, which is a cylindrical shape with open upper and lower parts so that the fixing component 110 can be housed inside; a snap-fit ​​component snap-fit ​​portion 133, which protrudes inward from the inner side of the snap-fit ​​component body 131 and has an inclined surface (second inclined surface) 133c that is inclined around the circumference in a manner opposite to the first inclined surface 112a; a snap-fit ​​component flange 132, which extends outward in a flat plate shape from the upper end of one side of the snap-fit ​​component body 131 and is formed into an annular shape; and a snap-fit ​​component fixing end 134, which protrudes downward from the bottom surface of the snap-fit ​​component flange 132.

[0063] The latching member latching portion 133 is formed in a plurality of portions spaced at predetermined intervals around the inner side surface of the latching member body 131. The latching member latching portion 133 may also be composed of a plurality of portions (i.e., at least 3) arranged radially in a manner corresponding to the fixing member latching portion 112.

[0064] The snap-fit ​​component snap-fit ​​portion 133 is formed into a generally quadrilateral block shape with a length around its circumference in the circumferential direction, and a second inclined surface 133c is formed on the upper side. The circumferential length of the upper end surface 133b is formed to be smaller than the circumferential length of the lower end surface 133a.

[0065] When the locking component 130 rotates, the second inclined surface 133c contacts the first inclined surface 112a and is guided along the rotation direction, and the contact position with the first inclined surface 112a changes. If the locking part 112 of the fixing component is located on the lower end surface 133a of the position overlapping with the locking part 133 of the locking component, the locking with the locking part 133 of the locking component is realized.

[0066] The locking end 134 of the snap-fit ​​component can be equipped as a second end 142 that serves as the other end of the elastic component 140, and in the state where the bracket cover 150 is detachably engaged, the locking end 134 of the snap-fit ​​component rotates integrally with the bracket cover 150 as the bracket cover 150 rotates.

[0067] The locking end 134 of the snap-fit ​​component includes: a main body connecting portion 134a, which is formed as a generally quadrilateral plate with a portion of the area between it and the snap-fit ​​component flange 132 cut off, and protrudes downward from the snap-fit ​​component flange 132; and a locking end extension 134b, which extends circumferentially from the lower end of the main body connecting portion 134a in the shape of a quadrilateral plate. The locking end extension 134b is spaced apart from the bottom surface of the snap-fit ​​component flange 132 to form the cut-off area. The upper end of the locking end extension 134b facing the bottom surface of the snap-fit ​​component flange 132 includes: a straight section placement portion 134d, formed on the side near the main body connecting portion 134a; a snap-fit ​​platform 134c, which protrudes upward from the end of the placement portion 134d; and a snap-fit ​​component inclined surface 134e, which extends downwardly inclined from the snap-fit ​​platform 134c.

[0068] The outer surfaces of the fixed end extension 134b and the main body connection 134a are integrally formed to form a continuous curved surface, and the radial thickness of the fixed end extension 134b is greater than the radial thickness of the main body connection 134a.

[0069] After the fixing protrusion 152 of the bracket cover 150 is inserted into the cut area of ​​the fixing end 134 of the snap-fit ​​component, if the fixing protrusion 152 is placed in the placement part 134d, the position of the fixing protrusion 152 is fixed between the main body connecting part 134a and the snap-fit ​​platform 134c, and when the bracket cover 150 rotates in the direction of the main body connecting part 134a, the bracket cover 150 and the snap-fit ​​component 130 can rotate as a whole.

[0070] The locking end 134 of the snap-fit ​​component is formed in a plurality of such portions around the bottom surface of the snap-fit ​​component flange 132. Preferably, the locking end 134 of the snap-fit ​​component can be formed by a plurality of such portions (i.e., at least 3) arranged radially.

[0071] The elastic member 140 is used to apply an elastic force to the snap-fit ​​member 130 to maintain the snap-fit ​​state between the fixing member 110 and the snap-fit ​​member 130.

[0072] The elastic component 140 is constructed using a torsion spring, which includes: a coil portion 141, which is wound in multiple segments to form a cylindrical coil shape; and a first end portion 143 and a second end portion 142, which are bent and extended from both ends of the coil portion 141, so that the first end portion 143 and the second end portion 142 are respectively snapped into the inner pot lid 50 and the snap-fit ​​component 130 and are elastically supported.

[0073] The first end portion 143 is formed into a curved shape that protrudes outward in a radial direction from one end of the coil portion 141, thereby being inserted into the fixing end groove 53b of one of the multiple inner pot lid fixing ends 53 of the inner pot lid 50 and being engaged by the fixing end engaging portion 53a.

[0074] The second end portion 142 is formed in a shape that bends from the other end of the coil portion 141 toward the length direction of the coil portion 141. The fixing end extension 134b of one of the plurality of fixing ends 134 of the locking member 130 is locked to the side end adjacent to the main body connecting portion 134a.

[0075] The coil portion 141 is configured to surround the outer side of the snap-fit ​​member body 131. The upper end of the coil portion 141 is supported by the bottom surface of the snap-fit ​​member flange 132, and the lower end of the coil portion 141 is supported by the bracket cover 150.

[0076] The bracket cover 150 is configured to rotate integrally with the snap-fit ​​member 130 when engaged with it, so as to release the snap-fit ​​state between the fixing member 110 and the snap-fit ​​member 130, thereby allowing the inner pot cover 50 to be separated from the cover 10.

[0077] The bracket cover 150 includes: a bracket cover body 151 covering the lower part of the through hole 51, the elastic member 140 and the snap-fit ​​member 130; and a fixing protrusion 152 protruding from the edge of the bracket cover body 151.

[0078] The bracket cover body 151 is formed into a flat cylindrical shape that is open at the top and closed at the bottom, including: a bracket cover flat plate portion 151a having a disc shape; and a bracket cover flange portion 151b extending upward from the edge of the bracket cover flat plate portion 151a.

[0079] A drain hole 151c extending vertically is formed in the center of the support cover plate portion 151a to allow steam to fall into the inner pot.

[0080] The outer side of the flange portion 151b of the bracket cover has a plurality of handle grooves 151d that are recessed inward. The user can easily grasp the bracket cover 150 with the handles and rotate the bracket cover 150 by means of the handle grooves 151d.

[0081] The fixing protrusion 152 is formed by cutting off a portion from the upper end of the flange portion 151b of the bracket cover and bending it inward. It is located on the upper part of the placement portion 134d between the main body connecting portion 134a and the locking platform 134c of the locking member 130, and is thus locked by the locking member 130. When the bracket cover 150 rotates, the locking member 130 rotates as a whole.

[0082] The fixing protrusions 152 can be formed in multiple ways around the bracket cover body 151, and can be composed of multiple (i.e., at least three) arranged radially in a manner corresponding to the fixing end 134 of the snap-fit ​​component.

[0083] Reference Figures 9 to 14 The assembly structure of the inner pot lid 50, the snap-fit ​​component 130, the elastic component 140, and the support cover 150 is described.

[0084] Figure 9 The process of inserting the snap-fit ​​component 130 into the through hole 51 of the inner pot lid 50 is shown. The snap-fit ​​component body 131 is inserted through the through hole 51 from top to bottom, such that the multiple snap-fit ​​component fixing ends 134 are respectively located between adjacent inner pot lid fixing ends 53.

[0085] Figure 10 Shown in Figure 9 The state before assembling the elastic component 140. Figure 11 The diagram shows the state after assembling the elastic component 140. The coil portion 141 of the elastic component 140 is configured to surround the outer side of the snap-fit ​​component body 131. The first end portion 143 is snapped into the snap-fit ​​portion 53a of the inner pot lid fixing end 53, and the second end portion 142 is snapped into the side of the snap-fit ​​component fixing end 134's fixing end extension 134b. In this case, the second end portion 142 contacts the fixing end extension 134b in the circumferential direction and is supported on the clockwise side of the fixing end extension 134b, whose thickness in the radial direction is greater than that of the main body connecting portion 134a, on the outer side in the radial direction (with...). Figure 11The second end 142 is prevented from detaching from the first end 143 (as a reference point). The length of the coil portion 141 can be stretched to engage the first end 143 and the second end 142 respectively.

[0086] Figure 12 Shown in Figure 11 The state before assembling the bracket cover 150, and Figure 13 This shows the state before the fixing protrusion 152 of the bracket cover 150 is placed in the mounting portion 134d. Figure 14 The bracket cover 150 is shown rotating so that the fixing protrusion 152 is positioned in the mounting portion 134d. The bracket cover 150 remains fixed at the plurality of fixing protrusions 152 arranged radially, thus achieving stable rotation of the bracket cover 150.

[0087] The support cover body 151 of the support cover 150 is located on the bottom part of the inner pot cover 50, surrounding the outer side of the snap-fit ​​member 130 and the elastic member 140, and as... Figure 13 As shown, the fixing protrusion 152 of the bracket cover 150 is located on the side of the inclined surface 134e of the snap-fit ​​component.

[0088] Subsequently, if the bracket cover is 150... Figure 13 Rotating clockwise around the reference point, then as follows Figure 14 As shown, the fixing protrusion 152 of the bracket cover 150 extends over the inclined surface 134e of the snap-fit ​​component and the snap-fit ​​platform 134c and is placed in the placement portion 134d.

[0089] As described above, with the bracket cover 150 engaged with the snap-fit ​​member 130, when the bracket cover 150 moves in one direction (towards...) Figure 14 When rotating clockwise (based on (b)), the fixing protrusion 152 transmits the rotational force to the main body connection 134a side, causing the bracket cover 150 and the snap-fit ​​member 130 to rotate as a unit. In this case, the elastic member 140 is in a position to apply force to the snap-fit ​​member 130 in another direction (towards... Figure 14 The elastic force rotates in a counterclockwise direction (based on (b)). Furthermore, the elastic member 140 is in a state where it receives compressive elastic force in the vertical direction (i.e., the elastic member 140 presses the bracket cover 150 downwards). Therefore, the adhesion force between the fixing protrusion 152 and the mounting portion 134d increases, allowing the fixing protrusion 152 to be stably maintained in the mounting portion 134d, and making it difficult to separate even if the bracket cover 150 rotates in the other direction.

[0090] exist Figure 14 In state (b), if Figure 14If the bracket cover 150 is pushed downwards based on (b) to counteract the pressure of the elastic member 140, and then the bracket cover 150 is rotated in the other direction, the bracket cover 150 will separate from the snap-fit ​​member 130 when the fixing protrusion 152 passes over the snap-fit ​​table 134c and rotates towards the snap-fit ​​member inclined surface 134e.

[0091] As described above, the elastic force of the elastic member 140 acts not only in the direction of the torque that applies rotational force to the snap-fit ​​member 130, but also in the direction of vertical compression, so as to maintain the stable snap-fit ​​state of the snap-fit ​​member 130 and thus prevent the user from arbitrarily disassembling it.

[0092] Reference Figures 15 to 17 The operation status of each component when assembling the inner pot lid 50, which is combined with the snap-fit ​​component 130, the elastic component 140 and the bracket cover 150, to the lid 10, which is combined with the fixing component 110, is described.

[0093] With the fixing plate fixing part 31 of the fixing plate 30 provided on the cover 10 engaged with the fixing member 110, in order to engage the inner pot lid 50, which is equipped with the snap-fit ​​member 130, the elastic member 140 and the bracket cover 150, with the inner pot lid 50, which is attached to the cover 10, it is positioned on the upper side of the cover 10 (to... Figure 15 (Based on the standard). In this case, multiple fixing component latching portions 112 and multiple latching component latching portions 133 are alternately arranged around the periphery in the circumferential direction, such as... Figure 15 As shown, the second inclined surface 133c of the snap-fit ​​component 130 is configured to contact the first inclined surface 112a of the snap-fit ​​component 112.

[0094] In this state, if the inner pot lid 50 is pushed further toward the lid 10 and moves relative to each other in a direction of approach, the locking member 130 overcomes the elastic force of the elastic member 140, and through the contact of the first inclined surface 112a and the second inclined surface 133c, the second inclined surface 133c moves along the first inclined surface 112a while the locking member 130 moves along the first direction (towards...). Figure 16 Rotate clockwise (based on the reference direction).

[0095] Subsequently, if the inner pot lid 50 is pushed further towards the lid 10, it will disengage from the contact area between the first inclined surface 112a and the second inclined surface 133c, as... Figure 17 As shown, by means of the elastic restoring force of the elastic member 140, the snap-fit ​​portion 133 of the snap-fit ​​member 130 moves in a second direction (which is opposite to the first direction) along a second direction. Figure 16 Rotating counterclockwise (based on the reference direction), the locking part 133 and the fixing part 112 are in a position of overlapping in the vertical direction, thus being in a locking state.

[0096] The snap-fit ​​component 133 and the fixing component 112 are formed in a radial pattern around the periphery. Therefore, if the snap-fit ​​component 130 and the fixing component 110 are snapped together, the fixing stability of the inner pot lid 50 can be improved, and the flow and eccentricity of the inner pot lid 50 can be prevented.

[0097] exist Figure 17 In the state where the support cover 150 rotates clockwise in the opposite direction to the elastic force of the elastic member 140, the support cover 150 and the locking member 130 rotate together, thereby releasing the locking state between the locking part 133 of the locking member and the locking part 112 of the fixing member, so that the inner pot cover 50 can be separated from the cover 10.

[0098] According to the structure described above, in the single-contact support device, the snap-fit ​​member 130, the elastic member 140, and the support cover 150 are combined with the inner pot lid 50, thereby allowing easy separation and cleaning of the inner pot lid 50. Furthermore, the user can easily separate the inner pot lid 50 from the lid 10 simply by rotating the support cover 150. Moreover, the snap-fit ​​between the fixing member 110 and the snap-fit ​​member 130 is achieved by rotation, thus minimizing wear caused by friction between the two parts and significantly reducing the possibility that the inner pot lid 50 may not separate due to constraint between the two parts.

[0099] <Second Embodiment>

[0100] Reference Figures 18 to 23 The electric cooking machine according to the second embodiment of the present invention will be described.

[0101] The electric cooking machine according to the second embodiment differs from the first embodiment in the composition of the snap-fit ​​component 130-1, the elastic component 140-1, and the support cover 150-1, and the electric cooking machine also includes a lower sealing component 160-1, while the rest of the composition is the same.

[0102] In the first and second embodiments, the configurations that are given the same reference numerals are the same, so detailed descriptions are omitted.

[0103] The snap-fit ​​component 130-1 is composed of a snap-fit ​​component body 131, a snap-fit ​​component flange 132, a snap-fit ​​component snap-fit ​​part 133, and a snap-fit ​​component fixing end 134-1.

[0104] When viewed from the side, the retaining end 134-1 of the snap-fit ​​component is a rectangular plate shape, and forms an arc shape around the body 131 of the snap-fit ​​component. Threads are formed on the outer surface of the retaining end 134-1 of the snap-fit ​​component.

[0105] The bracket cover 150-1 includes a bracket cover body 151-1 covering the lower part of the through hole 51, the snap-fit ​​member 130, and the elastic member 140. The bracket cover body 151-1 includes a bracket cover plate portion 151a with a disc shape and a bracket cover flange portion 151-1b extending upward from the edge of the bracket cover plate portion 151a. Threads are formed on the inner surface of the bracket cover flange portion 151-1b.

[0106] The threads of the flange portion 151-1b of the bracket cover and the threads of the fixing end 134-1 of the snap-fit ​​component are threaded together, thereby realizing the connection between the bracket cover 150-1 and the snap-fit ​​component 130-1.

[0107] If the bracket cover 150-1 is rotated in the opposite direction of the threaded connection, the connection between the bracket cover 150-1 and the snap-fit ​​member 130-1 is released, so that the bracket cover 150-1 can be separated from the snap-fit ​​member 130-1.

[0108] The elastic member 140-1 includes: a coil portion 141 having a cylindrical coil shape; and a first end portion 143 and a second end portion 142-1, which are bent outward in a radial direction from the two ends of the coil portion 141 respectively.

[0109] The first end 143 is engaged by the fixing end snap-fit ​​part 53a of one of the multiple inner pot lid fixing ends 53, and the second end 142-1 is engaged by one side end of the snap-fit ​​fixing end 134-1.

[0110] Both the first end 143 and the second end 142-1 protrude outward in the radial direction from both ends of the coil portion 141, thereby enabling stable engagement with the fixed end engagement portion 53a and the fixed end 134-1 of the engagement component.

[0111] The lower seal 160-1 is used to prevent the bracket cover 150-1 and the snap-fit ​​component 130-1 from being loosened in the threaded engagement state.

[0112] The lower seal 160-1 is annular in shape, and a recessed seal groove 161-1 is formed around the periphery of its upper surface. The lower end of the snap-fit ​​component body 131 is inserted into the seal groove 161-1.

[0113] As described above, if the bracket cover 150-1 and the snap-fit ​​member 130-1 are threaded together, the bracket cover 150-1 and the snap-fit ​​member 130-1 can be easily separated and joined. Furthermore, if the two ends of the elastic member 140-1 protrude outward in the radial direction and are snapped together, the assembly process of the elastic member 140-1 becomes easier, and a stable snap-fit ​​state of the elastic member 140-1 can be maintained.

[0114] As described above, the present invention has been described in detail through preferred embodiments, but the present invention is not limited to the above embodiments. Within the scope of the claims, the detailed description of the invention and the drawings, it can be implemented in various ways, and this also falls within the scope of the present invention.
