Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a base assembly and a cooking appliance. Background Technology

[0002] Users have increasingly higher requirements for the appearance of home appliances. When selecting materials for the control panel of some home appliances, it is necessary to consider the transparency requirements of the material, the temperature resistance requirements of the material, as well as the processability and price of the material. Therefore, after comprehensive consideration, transparent or semi-transparent PC material may be selected. During the use of PC material, stress problems may occur, which may lead to micro-cracks or cracks on the surface of the control panel, which will eventually manifest as a decrease in transparency, whitening of the surface, or even cracking. Utility Model Content

[0003] In view of this, the present invention provides a base assembly and a cooking appliance to solve the problem of the control panel turning white or even cracking due to high stress.

[0004] In a first aspect, this utility model provides a base assembly, comprising:

[0005] Support components;

[0006] A control panel is mounted on the support component, and the control panel is fixedly connected to the support component;

[0007] The base is connected to the supporting component via a limiting structure, which restricts the distance the base moves toward the control panel to not exceed a preset value.

[0008] Beneficial effects: The control panel is fixedly connected to the support component, preventing any movement of the control panel relative to the support component. The base is connected to the support component via a limiting structure, which restricts the distance the base can move towards the control panel to a preset value. Therefore, the deformation of the control panel caused by the base lifting it is limited, preventing whitening and cracking due to excessive stress from deformation. Thus, by setting a limiting structure to restrict the distance the base can move towards the control panel to a preset value, the problem of whitening and cracking caused by excessive stress on the control panel due to the base lifting it too far can be effectively prevented.

[0009] In one optional embodiment, the limiting structure is disposed on the base, and there is a gap between the limiting structure and the supporting component;

[0010] Alternatively, the limiting structure is provided on the supporting component, and there is a gap between the limiting structure and the base.

[0011] In one optional implementation, the limiting structure includes:

[0012] A first limiting part is provided on the supporting component;

[0013] A second limiting part is provided on the base. After the base and the supporting component are assembled, there is a first gap between the second limiting part and the first limiting part. The first gap is less than or equal to a preset value.

[0014] Beneficial effects: After the base and the support component are assembled, there is a first gap between the second limiting part and the first limiting part. The first gap is less than or equal to a preset value. Therefore, the first limiting part restricts the second limiting part from moving toward the control panel by a distance not exceeding the preset value. This effectively prevents the whitening and cracking problems caused by excessive stress on the control panel due to the base lifting the control panel by too much distance.

[0015] In one optional implementation, the preset value is 0.1 mm.

[0016] Beneficial effects: The preset value is 0.1mm. When the deformation of the control panel caused by being lifted by the base is 0.1mm, the stress at the lifted part of the control panel is 7.6MPa. The maximum working temperature of PC parts is 57℃, and the corresponding allowable stress requirement is less than 10MPa. Therefore, the stress at the lifted part of the control panel is less than the allowable stress, which can effectively prevent the whitening and cracking problems caused by excessive stress on the control panel due to the base lifting the control panel too far.

[0017] In one optional embodiment, a plurality of first limiting portions are provided along the circumference of the support member, and the second limiting portions are provided in a one-to-one correspondence with the first limiting portions.

[0018] Beneficial effects: Multiple first limiting parts are provided along the circumference of the supporting component, and the second limiting parts are provided one-to-one with the first limiting parts. This can effectively limit the base and prevent the whitening and cracking problems caused by excessive stress on the control panel due to the base lifting the control panel too far.

[0019] In one optional embodiment, the first limiting part is a protrusion disposed on the outer periphery of the support member, the base includes a side wall, and the second limiting part is a protrusion disposed on the side wall and extending upward.

[0020] Beneficial effects: When the protrusion and the raised part abut against each other, the raised part restricts the upward movement of the base, thereby ensuring that the base is in a fixed position on the supporting component. This effectively prevents the whitening and cracking problems caused by excessive stress on the control panel due to the base lifting the control panel too far. The first limiting part is a raised part, and the second limiting part is a raised part. The limiting structure is simple and has low processing cost.

[0021] In one optional embodiment, the support member is provided with a plurality of first engaging portions, and the base is provided with a corresponding second engaging portion. The first engaging portions engage with the second engaging portions and prevent the base from moving away from the control panel.

[0022] Beneficial effects: The first and second locking parts engage and prevent the base from moving away from the control panel, thus ensuring no gap between the base and the control panel and a more aesthetically pleasing appearance. Furthermore, the base and support components engage easily and conveniently.

[0023] In one alternative embodiment, the control panel is secured to the support member by screws and / or snap-fit ​​structures.

[0024] Beneficial effects: The control panel is fixed to the support component by screws and / or snap-fit ​​structure. The control panel is stably assembled on the support component and will not move relative to the support component.

[0025] In one optional embodiment, the base assembly further includes a fixing frame and a base cover. The fixing frame is disposed inside the base and below the supporting member. The base cover is disposed at the bottom of the base. The base cover is integrally formed or fixedly connected to the base. The supporting member and the base cover are respectively fixed to the fixing frame so that the base and the supporting member are tightly connected.

[0026] Beneficial effects: The base cover seals the lower end of the base, and the base cover is integrally formed or fixedly connected to the base. The supporting component and the base cover are fixed to the fixing frame respectively, which can assemble the entire base assembly together and achieve a tight connection between the base and the supporting component.

[0027] In one alternative embodiment, a second gap exists between the base cover and the fixing frame, the second gap being larger than the preset value.

[0028] Beneficial effects: There is a second gap between the base cover and the fixing frame. The second gap is greater than the preset value. The base can move upward by the preset value. Since there are manufacturing tolerances in the height direction of the supporting components, fixing frame, base and base cover parts, the part of the second gap that exceeds the preset value can cause the base cover and fixing frame to deform to a certain extent, thereby achieving a tight fit between the supporting components and fixing frame, fixing frame and base, and base and base cover. The deformation mainly occurs on the fixing frame and base cover, and the deformation of these parts will not cause appearance problems.

[0029] In one alternative implementation, the second gap is L, where 0.1 mm ≤ L ≤ 0.6 mm.

[0030] Secondly, this utility model also provides a cooking appliance, comprising:

[0031] The aforementioned base assembly.

[0032] Beneficial effects: In this cooking appliance, the control panel is fixedly connected to the supporting component, preventing the control panel from moving relative to the supporting component. The base and supporting component are connected by a limiting structure, which restricts the distance the base can move toward the control panel to a preset value. Therefore, the deformation of the control panel caused by the base lifting it is limited, and the control panel will not turn white or crack due to excessive stress caused by deformation. By setting the limiting structure, the distance the base can move toward the control panel is limited to a preset value, which can effectively prevent the whitening and cracking problems caused by excessive stress on the control panel due to the base lifting it too far.

[0033] In one alternative implementation, the cooking appliance is an electric kettle. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0052] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0053] Users have increasingly higher requirements for the appearance of home appliances. When selecting materials for the control panel of some home appliances, it is necessary to consider the transparency requirements of the material, the temperature resistance requirements of the material, as well as the processability and price of the material. Therefore, after comprehensive consideration, transparent or semi-transparent PC material may be selected. During the use of PC material, stress problems may occur, which may lead to micro-cracks or cracks on the surface of the control panel, which will eventually manifest as a decrease in transparency, whitening of the surface, or even cracking.

[0054] There are many reasons for stress problems in PC materials, especially those caused by assembly. The appearance of the product requires a complete and seamless fit, especially for the control panel, which requires a seamless fit between itself and the base. However, the assembly of components often has manufacturing tolerances. Therefore, after assembling the components, these components need to be connected more tightly with screws. During the screwing process, the base and the control panel will move relative to each other, which will cause the control panel to be squeezed and deformed.

[0055] The following is combined Figures 1 to 12 The following describes embodiments of the present invention.

[0056] According to an embodiment of the present invention, a base assembly is provided, including a support component 1, a control panel 2, and a base 3.

[0057] The control panel 2 is mounted on the support component 1 and is fixedly connected to the support component 1; the base 3 is connected to the support component 1 through a limiting structure, which restricts the distance the base 3 moves toward the control panel 2 to not exceed a preset value.

[0058] In this embodiment, the control panel 2 is fixedly connected to the support component 1, and the control panel 2 will not move relative to the support component 1. The base 3 is connected to the support component 1 through a limiting structure. The limiting structure restricts the distance that the base 3 moves toward the control panel 2 to not exceed a preset value. Therefore, the deformation of the control panel 2 caused by being lifted by the base 3 is limited, and the control panel 2 will not cause whitening or cracking due to excessive stress caused by deformation. By setting the limiting structure, the limiting structure restricts the distance that the base 3 moves toward the control panel 2 to not exceed a preset value, which can effectively prevent whitening and cracking caused by excessive stress on the control panel 2 due to the base 3 lifting the control panel 2 too far.

[0059] Specifically, when the base 3 moves a preset distance toward the control panel 2, the stress on the control panel 2 during deformation is less than the required stress.

[0060] When the deformation of the control panel 2 caused by the base 3 is within the preset value, the stress on the control panel 2 during deformation is less than the allowable stress, and the control panel 2 will not cause problems such as whitening or cracking due to excessive stress.

[0061] In one specific embodiment, the control panel 2 is made of PC material.

[0062] In one specific embodiment, the control panel 2 is located at the very top of the entire base assembly. The control panel 2 serves as an exterior component and has an operating area.

[0063] Specifically in one embodiment, such as Figure 1 As shown, the control panel 2 has a brim-shaped structure, the support component 1 has a ring-shaped structure, including a ring-shaped wall 101 extending in the vertical direction and a brim-shaped support part 102. The control panel 2 is connected to the support part 102 and covers the support part 102. The base 3 has a ring-shaped structure, and the top shape of the base 3 is consistent with the edge shape of the control panel 2.

[0064] Specifically in one embodiment, such as Figure 1 As shown, the support part 102 of the support component 1 has a notch, and the base assembly also includes a control plate, which is located inside the base 3 and outside the support component 1. The control plate passes through the notch and is connected to the control panel 2.

[0065] In one embodiment, the limiting structure is disposed on the base 3, and there is a gap between the limiting structure and the supporting member 1; or, the limiting structure is disposed on the supporting member 1, and there is a gap between the limiting structure and the base 3.

[0066] In one embodiment, the limiting structure includes a first limiting part 103 and a second limiting part 301. The first limiting part 103 is disposed on the support member 1; the second limiting part 301 is disposed on the base 3. After the base 3 and the support member 1 are assembled, there is a first gap between the second limiting part 301 and the first limiting part 103. The first gap is less than or equal to a preset value.

[0067] In this embodiment, after the base 3 and the support component 1 are assembled, specifically referring to the assembly of the base 3 and the support component 1 but excluding the subsequent screw tightening process, the second limiting part 301 is located below the first limiting part 103, and there is a first gap between the second limiting part 301 and the first limiting part 103. The first gap is less than or equal to a preset value. During the process of further tightening by screws, the first limiting part 103 restricts the distance that the second limiting part 301 moves toward the control panel 2 to not exceed the preset value, thereby limiting the distance that the base 3 moves toward the control panel 2 to not exceed the preset value. This can effectively prevent the whitening and cracking problems caused by excessive stress on the control panel 2 due to the base 3 lifting the control panel 2 by too large a distance.

[0068] In one specific embodiment, after the base 3 and the support component 1 are assembled, the second limiting part 301 is located below the first limiting part 103, and the first limiting part 103 restricts the upward movement of the second limiting part 301 to not exceed a preset value.

[0069] In one embodiment, the preset value is 0.1 mm.

[0070] In this embodiment, the preset value is 0.1mm. When the deformation of the control panel 2 caused by being lifted by the base 3 is 0.1mm, the stress at the point where the control panel 2 is lifted is 7.6MPa. The maximum working temperature of the PC parts is 57℃, and the corresponding allowable stress requirement is less than 10MPa. Therefore, the stress at the point where the control panel 2 is lifted is less than the allowable stress, which can effectively prevent the whitening and cracking problems caused by excessive stress on the control panel 2 due to the base 3 lifting the control panel 2 by too large a distance.

[0071] In one specific embodiment, the allowable stress of the PC material decreases as the temperature increases. At -20°C, the allowable stress of the PC material is approximately 16 MPa; at 0°C, it is approximately 15 MPa; at 20°C, it is approximately 14 MPa; at 35°C, it is approximately 12.7 MPa; at 40°C, it is approximately 12.5 MPa; at 45°C, it is approximately 11.8 MPa; at 80°C, it is approximately 6.8 MPa; and at 100°C, it is approximately 3 MPa.

[0072] This base assembly is used for electric kettles. After testing, the highest temperature of the control panel 2 is 57℃, and the corresponding allowable stress requirement is less than 10MPa. Therefore, the preset value is set to 0.1mm, which allows the base 3 to have a range of motion of no more than 0.1mm. This avoids increased assembly difficulty due to dimensional errors, facilitates the assembly of the base 3, and effectively prevents whitening and cracking problems caused by excessive stress on the control panel 2 due to the base 3 lifting the control panel 2 by too much distance.

[0073] In one embodiment, a plurality of first limiting portions 103 are provided along the circumference of the support member 1, and second limiting portions 301 are provided in a one-to-one correspondence with the first limiting portions 103.

[0074] In this embodiment, multiple first limiting parts 103 are provided along the circumference of the support member 1, and second limiting parts 301 are provided in correspondence with the first limiting parts 103. This can effectively limit the base 3 and effectively prevent the whitening and cracking of the control panel 2 caused by excessive stress due to the base 3 lifting the control panel 2 by too much distance.

[0075] In one specific embodiment, four first limiting parts 103 are provided along the circumference of the support member 1, and the second limiting parts 301 are provided in a one-to-one correspondence with the first limiting parts 103.

[0076] In one embodiment, the first limiting part 103 is a protrusion disposed on the outer periphery of the support member 1, the base 3 includes a side wall, and the second limiting part 301 is a protrusion disposed on the side wall and extending upward.

[0077] In this embodiment, when the protrusion abuts against the extended portion, the extended portion restricts the upward movement of the base 3, thereby ensuring that the base 3 remains in the fixed position of the support member 1. This effectively prevents the whitening and cracking of the control panel 2 caused by excessive stress due to the base 3 lifting the control panel 2 by too much distance. The first limiting portion 103 is a protrusion, and the second limiting portion 301 is a protrusion. The limiting structure is simple and has low processing cost.

[0078] In one embodiment not shown in the figure, the protrusion may not be provided, and the second limiting part 301 may be able to abut against the support member 1 in the vertical direction.

[0079] Specifically in one embodiment, such as Figure 7As shown, the gap between the protrusion and the protrusion is S, where S = 0.1 mm. The base 3 can move upward by 0.1 mm, and the control panel 2 is deformed by 0.1 mm by being lifted by the base 3. The stress at the lifted part of the control panel 2 is 7.6 MPa, while the maximum working temperature of PC parts is 57℃, and the corresponding allowable stress requirement is less than 10 MPa. Therefore, the stress at the lifted part of the control panel 2 is less than the allowable stress, which can effectively prevent the whitening and cracking problems caused by excessive stress on the control panel 2 due to the base 3 lifting the control panel 2 by too large a distance.

[0080] In one embodiment, the support member 1 is provided with a plurality of first engaging portions 104, and the base 3 is provided with a corresponding second engaging portion 302. The first engaging portions 104 engage with the second engaging portions 302 and prevent the base 3 from moving away from the control panel 2.

[0081] In this embodiment, the first engaging portion 104 and the second engaging portion 302 engage and prevent the base 3 from moving away from the control panel 2, thereby ensuring that there is no gap between the base 3 and the control panel 2, resulting in a more aesthetically pleasing appearance. Furthermore, the base 3 engages with the support component 1, making their assembly simple and convenient.

[0082] In one specific embodiment, the support component 1 is provided with six first engaging parts 104, and the base 3 is provided with six corresponding second engaging parts 302.

[0083] Specifically in one embodiment, such as Figure 4 As shown, the first engaging portion 104 includes a first elastic arm 1041 extending downward from the top edge of the support member 1 and a first engaging protrusion 1042 disposed at the lower end of the first elastic arm 1041. The second engaging portion 302 includes a second elastic arm 3021 extending upward from the side wall of the base 3 and a second engaging protrusion 3022 disposed at the top end of the second elastic arm 3021. The lower surface of the second engaging protrusion 3022 abuts against the upper surface of the first engaging protrusion 1042.

[0084] To facilitate the smooth engagement of the first engaging portion 104 and the second engaging portion 302, the first engaging protrusion 1042 is provided with a first guide slope 1043, and the second engaging protrusion 3022 is provided with a second guide slope 3023.

[0085] In one embodiment, the control panel 2 is fixed to the support member 1 by screws and / or snap-fit ​​structure 106.

[0086] In this embodiment, the control panel 2 is fixed to the support member 1 by screws and / or snap-fit ​​structure 106. The control panel 2 is stably assembled on the support member 1 and will not move relative to the support member 1.

[0087] In one specific embodiment, the control panel 2 is fixed to the support member 1 by both screws and snap-fit ​​structure 106.

[0088] In one specific embodiment, the control panel 2 is provided with a plurality of first screw posts 201, and the support portion 102 of the support component 1 is provided with a plurality of second screw posts 105. The screw passes through the second screw posts 105 and is tightened in the first screw posts 201.

[0089] In one specific embodiment, the control panel 2 is provided with a slot 202, and the edge of the support portion 102 of the support component 1 is provided with a plurality of fastening structures 106, which engage with the slot 202.

[0090] In one embodiment, the base assembly further includes a fixing frame 4 and a base cover 5. The fixing frame 4 is disposed inside the base 3 and below the support member 1. The base cover 5 is disposed at the bottom of the base 3. The base cover 5 is integrally formed or fixedly connected to the base 3. The support member 1 and the base cover 5 are respectively fixed to the fixing frame 4 so that the base 3 and the support member 1 are tightly connected.

[0091] In this embodiment, the base cover 5 is integrally formed or fixedly connected to the lower end of the base 3. The support component 1 and the base cover 5 are respectively fixed to the fixing frame 4, so that the entire base assembly can be assembled together and the base 3 and the support component 1 can be tightly connected.

[0092] It should be noted that the base cover 5 can be connected to the base 3 as an integral structure through a snap-fit ​​or limiting structure, or it can be molded as a single piece.

[0093] Specifically, the support component 1 is fixedly connected to one end of the fixing frame 4, and the base cover 5 is fixed to the other end of the fixing frame 4. Through the fixed connection between the base cover 5 and the fixing frame 4, the base 3 is tightly fixed to the support component 1.

[0094] Specifically, the support component 1 and the base cover 5 are both fixed to the fixing frame 4 by screws.

[0095] It should be noted that the support component 1 and the base cover 5 are both fixed to the fixing frame 4 by screws. During the screw connection process, the base 3 will deform to a certain extent. By setting a limiting structure, the limiting structure restricts the distance that the base 3 moves toward the control panel 2 to not exceed a preset value. This can effectively prevent the whitening and cracking problems caused by excessive stress on the control panel 2 due to the base 3 lifting the control panel 2 too far.

[0096] In one embodiment, there is a second gap between the base cover 5 and the fixing frame 4, and the second gap is greater than a preset value.

[0097] In this embodiment, there is a second gap between the base cover 5 and the fixing frame 4. The second gap is greater than a preset value. The base 3 can move upward by a preset value. The part of the second gap that exceeds the preset value can cause the base cover 5 and the fixing frame 4 to deform to a certain extent, thereby achieving a tight fit between the support component 1 and the fixing frame 4, the fixing frame 4 and the base 3, and the base 3 and the base cover 5. The deformation mainly occurs on the fixing frame 4 and the base cover 5. The deformation of these parts will not cause any appearance problems.

[0098] Specifically, such as Figure 9 and Figure 10 The screw passes through the base cover 5 from bottom to top and is tightened in the screw post of the fixing bracket 4. Therefore, the deformation that occurs during the tightening process is located on the base cover 5, the bottom of the base 3 and the fixing bracket 4, and will not affect the appearance of the entire base assembly.

[0099] Specifically in one embodiment, such as Figure 10 As shown, the second gap is L, 0.1mm≤L≤0.6mm.

[0100] In one specific embodiment, L is 0.6 mm.

[0101] In one specific embodiment, the base cover 5 is provided with a groove 501, the bottom of the groove 501 is provided with a screw hole 502, the fixing bracket 4 is provided with a third screw post 401, the third screw post 401 extends into the groove 501, and the gap between the lower end of the third screw post 401 and the screw hole 502 constitutes a second gap.

[0102] In one specific embodiment, the base assembly further includes a heating element disposed inside the base 3, and the heating element is disposed on the fixed base.

[0103] According to an embodiment of the present invention, another aspect also provides a cooking appliance, such as... Figure 11 and Figure 12 This includes: the base assembly provided in the above embodiments.

[0104] In this cooking appliance, the control panel 2 is fixedly connected to the support component 1, and the control panel 2 will not move relative to the support component 1. The base 3 is connected to the control panel 2 through a limiting structure. The limiting structure restricts the distance that the base 3 can move toward the control panel 2 to not exceed a preset value. Therefore, the deformation of the control panel 2 caused by being lifted by the base 3 is limited, and the control panel 2 will not suffer from excessive stress due to deformation, resulting in whitening or cracking. By setting the limiting structure, the limiting structure restricts the distance that the base 3 can move toward the control panel 2 to not exceed a preset value, which can effectively prevent the whitening or cracking of the control panel 2 caused by excessive stress due to the base 3 lifting the control panel 2 too far.

[0105] In one specific embodiment, the cooking appliance is an electric kettle.

[0106] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
