Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to wire fixing components, base components, and household appliances. Background Technology
[0002] As users' demands for product functionality diversify, small kitchen appliances such as electric kettles and rice cookers are also developing towards greater functionality and intelligence. With increased product functionality but limited internal space, each functional module needs to perform its corresponding function within a smaller volume. Safety standards for household appliances stipulate that electrical wires must withstand a certain amount of force without loosening, thus requiring wire securing. Related technologies, for example... Figure 1 A pressure plate component needs to be designed, which works with the base to secure the power cord. Because this requires an additional pressure plate component, which needs to be assembled with the base, the cost is high, the assembly process is cumbersome, and the pressure plate occupies a significant amount of space. Utility Model Content
[0003] In view of this, the present invention provides an electrical wire fixing assembly, a base assembly, and a household appliance to solve the problem that related technologies require additional pressure plates to fix the electrical wires.
[0004] In a first aspect, this utility model provides an electrical wire fixing assembly, comprising:
[0005] The first assembly component is equipped with a cable channel;
[0006] The second assembly is disposed on the first assembly;
[0007] The wire is partially disposed in the wire groove. The second fitting cooperates with the first fitting to press the wire into the wire groove. The interference of the wire caused by the pressure of the first fitting and the second fitting is Δh, where 1.05mm≤Δh≤1.95mm.
[0008] Beneficial effects: The first assembly has a wire groove; the wire portion is placed within the wire groove. The second assembly cooperates with the first assembly to press the wire firmly into the wire groove. The wire is fixed using the second and first assemblies. Compared with related technologies, no additional pressure plate is needed, reducing parts and assembly steps, and also reducing space occupation. Furthermore, because the interference fit of the wire caused by the pressure from the first and second assemblies is between 1.05mm and 1.95mm, it avoids excessive interference fit, which could lead to excessive deformation of the insulation layer and the risk of insulation failure and leakage after long-term operation. At the same time, it ensures that the wire fixing effect meets standard requirements.
[0009] In one optional embodiment, the wire groove is provided with a first pressure rib, the second assembly is provided with a second pressure rib, and the wire is clamped between the first pressure rib and the second pressure rib.
[0010] Beneficial effects: By setting the first pressure rib in the online groove and the second pressure rib in the second assembly, the wire is clamped between the first pressure rib and the second pressure rib. The first pressure rib and the second pressure rib work together to press the wire tightly. The setting of the first pressure rib and the second pressure rib can increase the contact area with the wire and increase the friction with the wire. When the wire is pulled outside the first assembly, the wire will not come loose.
[0011] In one optional embodiment, the diameter of the wire is φ, the maximum distance between the side of the first reinforcing rib that contacts the wire and the plane of the second assembly is H, the distance between the second reinforcing rib and the plane of the second assembly is h, and Δh=φ+hH.
[0012] In one alternative embodiment, the first reinforcing rib has an arc-shaped bottom surface, and the maximum distance between the arc-shaped bottom surface and the plane of the second assembly is H.
[0013] Beneficial effects: The first pressure rib has an arc-shaped bottom surface, which can increase the contact area with the power cord and increase the friction with the power cord. When the power cord is pulled outside the base, the power cord will not come loose.
[0014] In one alternative embodiment, the first reinforcing rib further has two side surfaces connected to both ends of the arc-shaped bottom surface.
[0015] Beneficial effects: The first pressure rib has an arc-shaped bottom surface and two sides connected to the two ends of the arc-shaped bottom surface, which can further increase the contact area with the power cord and increase the friction with the power cord. When the power cord is pulled outside the base, the power cord will not come loose.
[0016] In one optional embodiment, multiple first reinforcing ribs are spaced apart, and the second reinforcing ribs are one-to-one opposite to the first reinforcing ribs.
[0017] Beneficial effects: By setting multiple first pressure ribs at intervals, and having multiple second pressure ribs one-to-one with the first pressure ribs, the wires can be more firmly fixed in the wire groove, increasing the contact area with the wires and increasing the friction with the wires. When the wires are pulled from the outside of the first assembly, the wires will not come loose.
[0018] In one alternative embodiment, the second pressure rib is disposed within the opening of the groove.
[0019] Beneficial effects: Since the second pressure rib is located inside the opening of the wire groove, the distance between the second pressure rib and the first pressure rib can be further reduced, ensuring that the wire is pressed tightly and that the wire will not come loose when the wire is pulled outside the first assembly.
[0020] In one optional embodiment, the side wall of the first assembly is provided with an inlet that communicates with the wire groove, and the first assembly is provided with an outlet at the end of the wire groove away from the inlet. A wire buckle is provided at the outlet or at a position on the first assembly near the outlet.
[0021] Beneficial effect: By setting a wire clip at the outlet or near the outlet on the first assembly, the wire can be pre-secured.
[0022] In one alternative embodiment, the second assembly is provided with a groove for receiving the wire groove.
[0023] Beneficial effect: By setting a groove in the second assembly, the wire groove can be accommodated in the groove, which can make the connection between the second assembly and the first assembly tighter.
[0024] Secondly, this utility model also provides a base assembly, including the aforementioned wire fixing assembly and a fixing frame, wherein the fixing frame passes through the first assembly and is fixedly connected to the second assembly.
[0025] Beneficial effects: The first assembly has a wire groove, and the fixing bracket is located inside the first assembly. The wire portion is placed in the wire groove. The fixing bracket passes through the first assembly and is fixedly connected to the second assembly. After the second assembly is fixed to the fixing bracket, the second assembly and the first assembly are relatively fixed. The cooperation between the second assembly and the first assembly presses the wire tightly into the wire groove. The wire is fixed by the second assembly and the first assembly. Compared with related technologies, there is no need to set up an additional pressure plate, reducing the number of parts and assembly steps, and also reducing the space occupied. In addition, since the interference of the wire caused by the pressure of the first and second assemblies is between 1.05mm and 1.95mm, it can avoid the risk of insulation layer failure and leakage after long-term operation due to excessive interference of the wire. At the same time, it can ensure that the wire fixing effect meets the standard requirements.
[0026] In one alternative embodiment, the mounting bracket has one of a screw post or a screw hole, the second assembly has the other of a screw post or a screw hole, the first assembly has a through hole through which the screw post passes, and the groove surrounds the through hole.
[0027] Beneficial effects: The fixing bracket has one of the screw posts or screw holes, the second assembly has the other of the screw posts or screw holes, and the first assembly has a through hole for the screw posts to pass through. The wire groove surrounds the through hole, so the wire groove surrounds the screw posts. The entire wire groove has a large length, which increases the contact area with the wire. At the same time, the screw posts can provide support when the wire is under tension, and the structural strength of the screw posts themselves can be used to prevent the wire from being pulled out directly.
[0028] In one alternative embodiment, the screw post abuts against the outer wall of the groove.
[0029] Beneficial effects: Since the screw post abuts against the outer wall of the wire trough, it can prevent the wire trough from deforming. In particular, when the wire is under tension, the screw post can provide support for the wire trough and prevent the wire trough from deforming.
[0030] Thirdly, this utility model also provides a household appliance, including the aforementioned base assembly.
[0031] Beneficial effects: In this household appliance, the first assembly has a wire channel, and the fixing bracket is located inside the first assembly. The wire is placed inside the wire channel. The fixing bracket passes through the first assembly and is connected to the second assembly by screws. After the second assembly is fixed to the fixing bracket, the second assembly and the first assembly are relatively fixed. The cooperation between the second assembly and the first assembly presses the wire tightly into the wire channel. By using the second assembly and the first assembly to fix the wire, compared with related technologies, no additional pressure plate is required, reducing the number of parts and assembly steps, and also reducing the space occupied. In addition, since the interference of the wire caused by the pressure of the first and second assemblies is between 1.05mm and 1.95mm, it can avoid the risk of insulation layer failure and leakage after long-term operation due to excessive interference of the wire, which could lead to excessive deformation of the insulation layer. At the same time, it can ensure that the wire fixing effect meets the standard requirements.
[0032] In one alternative implementation, the household appliance is an electric kettle. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0045] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0047] 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.
[0048] As users' demands for product functionality diversify, small kitchen appliances such as electric kettles and rice cookers are also developing towards greater functionality and intelligence. With increased product functionality but limited internal space, each functional module needs to perform its corresponding function within a smaller volume. Safety standards for household appliances stipulate that electrical wires must withstand a certain amount of force without loosening, thus requiring wire securing. Related technologies, for example... Figure 1 and Figure 2 A pressure plate component needs to be designed, which works with the base plate 100' to fix the wires. Since an additional pressure plate component is required, the pressure plate needs to be assembled with the base plate 100', which is costly, complicated in assembly process, and takes up a lot of space.
[0049] Further integration Figure 1 and Figure 2 , Figure 1The base plate 100' is provided with a cable tray 1001' through which the power supply line passes. The cable tray 1001' is relatively small. The pressure plate 200' is fixedly connected to the base plate 100' by screws. When the wire passes through the cable tray 1001', the pressure plate 200' presses the wire tightly. Because the cable tray 1001' is relatively small, the contact area between the pressure plate 200' and the wire is small, resulting in poor overall fixation of the wire. Furthermore, the pressure plate 200' is close to wire contact, which can easily cause deformation and damage to the insulation layer, leading to the risk of insulation layer failure and leakage after long-term operation.
[0050] It should be noted that the household appliances in the relevant technology include a base, with the base plate 100' located at the bottom of the base.
[0051] The following is combined with Figures 3 to 7 The following describes embodiments of the present invention.
[0052] According to an embodiment of the present invention, in a first aspect, a wire fixing assembly is provided, including a first fitting 1, a wire, and a second fitting 2.
[0053] The first assembly 1 is provided with a wire groove 101; the second assembly 2 is provided in the first assembly 1; the wire part is provided in the wire groove 101, and the second assembly 2 cooperates with the first assembly 1 to press the wire into the wire groove 101. The interference of the wire caused by the pressure of the first assembly 1 and the second assembly 2 is Δh, 1.05mm≤Δh≤1.95mm.
[0054] In this embodiment, the first assembly 1 has a wire groove 101; the wire portion is disposed within the wire groove 101, and the second assembly 2 cooperates with the first assembly 1 to press the wire tightly into the wire groove 101. The wire is fixed using the second assembly 2 and the first assembly 1. Compared with related technologies, no additional pressure plate is required, reducing the number of parts and assembly steps, and also reducing the space occupied. Furthermore, since the interference fit of the wire under the pressure of the first assembly 1 and the second assembly 2 is between 1.05mm and 1.95mm, it avoids excessive interference fit, which could lead to excessive deformation of the insulation layer and the risk of insulation failure and leakage after long-term operation. Simultaneously, it ensures that the wire fixing effect meets the standard requirements.
[0055] It should be noted that the first assembly 1 and the second assembly 2 can be directly fixed, or they can be fixed by other components so that the first assembly 1 and the second assembly 2 come into contact.
[0056] In one specific embodiment, the second assembly 2 is disposed at the bottom of the first assembly 1.
[0057] Specifically in one embodiment, such as Figure 3 and Figure 4As shown, the wire trough 101 is located at the bottom of the first assembly 1, and the second assembly 2 cooperates with the first assembly 1 to press the wire into the wire trough 101.
[0058] Specifically, with the wire trough 101 facing downwards, during assembly, the first assembly 1 is first flipped over so that the wire trough 101 faces upwards, and the wire is placed inside the wire trough 101. Then, the second assembly 2 is assembled. After the second assembly 2 is assembled, the wire is pressed tightly into the wire trough 101.
[0059] In one specific embodiment, the first assembly 1 includes an annular sidewall and a bottom annular mounting plate, with a wire groove 101 disposed on the bottom annular mounting plate.
[0060] It should be noted that the second assembly 2 being located on the first assembly 1 can specifically mean that the second assembly 2 is fixedly connected to the first assembly 1, or it can mean that the second assembly 2 is fixedly connected to other structural components inside the first assembly 1. When the second assembly 2 is fixedly connected to other structural components inside the first assembly 1, the second assembly 2 is indirectly fixed to the bottom of the first assembly 1.
[0061] In one embodiment, the wire trough 101 is provided with a first pressure rib 102, the second assembly 2 is provided with a second pressure rib 201, and the wire is clamped between the first pressure rib 102 and the second pressure rib 201.
[0062] In this embodiment, a first pressure rib 102 is provided in the wire groove 101, and a second pressure rib 201 is provided in the second assembly 2. The wire is clamped between the first pressure rib 102 and the second pressure rib 201. The second pressure rib 201 cooperates with the first pressure rib 102 to press the wire tightly. The setting of the second pressure rib 201 and the first pressure rib 102 can increase the contact area with the wire and increase the friction with the wire. When the wire is pulled outside the first assembly 1, the wire will not come loose.
[0063] In one embodiment, the diameter of the wire is φ, the maximum distance between the side of the first reinforcing rib 102 that contacts the wire and the plane of the second assembly 2 is H, the distance between the second reinforcing rib 201 and the plane of the second assembly 2 is h, Δh=φ+hH, 1.05mm≤Δh≤1.95mm.
[0064] In this embodiment, the interference caused by the pressure of the first pressure rib 102 and the second pressure rib 201 on the wire is between 1.05mm and 1.95mm. This can avoid the wire being subjected to excessive interference, which would lead to excessive deformation of the insulation layer and the risk of insulation layer failure and leakage after long-term operation. At the same time, it can ensure that the wire fixing effect meets the standard requirements.
[0065] In one specific embodiment, the first pressure rib 102 has an arc-shaped bottom surface 1021, the diameter of the wire is φ, the interference of the wire caused by the pressure of the first pressure rib 102 and the second pressure rib 201 is Δh, the maximum distance between the arc-shaped bottom surface 1021 and the plane of the second assembly 2 is H, the distance between the second pressure rib 201 and the plane of the second assembly 2 is h, Δh=φ+hH, 1.05mm≤Δh≤1.95mm.
[0066] In one specific embodiment, the interference of the wire caused by the pressure of the first pressure rib 102 and the second pressure rib 201 is 1.05mm.
[0067] In one specific embodiment, the interference of the wire caused by the pressure of the first pressure rib 102 and the second pressure rib 201 is 1.55mm.
[0068] In one specific embodiment, the interference of the wire caused by the pressure of the first pressure rib 102 and the second pressure rib 201 is 1.95mm.
[0069] It should be noted that, in this embodiment, by limiting the interference caused by the pressure of the first pressure rib 102 and the second pressure rib 201 on the wire, and combining this with the diameter of the wire itself, once the maximum distance between the side of the first pressure rib 102 that contacts the wire and the plane of the second assembly 2 is determined, the distance between the second pressure rib 201 and the plane of the second assembly 2 can be derived in reverse. Therefore, when designing the dimensions of the first pressure rib 102 and the second pressure rib 201, the maximum distance between the side of the first pressure rib 102 that contacts the wire and the plane of the second assembly 2 can be designed first, and then the distance between the second pressure rib 201 and the plane of the second assembly 2 can be obtained.
[0070] In one embodiment, a plurality of first reinforcing ribs 102 are provided at intervals, and second reinforcing ribs 201 are opposite to the first reinforcing ribs 102 one by one.
[0071] In this embodiment, by setting multiple first pressure ribs 102 at intervals and having multiple second pressure ribs 201 opposite to the first pressure ribs 102, the wire can be further firmly fixed in the wire groove 101, increasing the contact area with the wire and increasing the friction with the wire, so that the wire will not come loose when the wire is pulled outside the first assembly 1.
[0072] In one embodiment, the first reinforcing rib 102 has an arc-shaped bottom surface 1021, and the maximum distance between the arc-shaped bottom surface 1021 and the plane of the second assembly 2 is H.
[0073] In this embodiment, the first pressure rib 102 has an arc-shaped bottom surface 1021, which can increase the contact area with the wire and increase the friction with the wire, so that the wire will not come loose when the wire is pulled outside the first assembly 1.
[0074] Of course, in other alternative embodiments, the first rib 102 may be horizontally arranged and have a horizontal bottom surface.
[0075] In one embodiment, the first reinforcing rib 102 also has two side surfaces 1022 connected to the two ends of the arc-shaped bottom surface 1021.
[0076] In this embodiment, the first pressure rib 102 has an arc-shaped bottom surface 1021 and two side surfaces 1022 connected to the two ends of the arc-shaped bottom surface 1021, which can further increase the contact area with the wire and increase the friction with the wire, so that the wire will not come loose when the wire is pulled outside the first assembly 1.
[0077] It should be noted that the household appliances in the related technology include a base, with a base plate located at the bottom of the base. The base plate has a wire passage groove through which the power supply wire passes. The wire passage groove is relatively small. The pressure plate is fixedly connected to the first assembly 1 by screws. When the wire passes through the groove, the pressure plate presses the wire tightly. An additional pressure plate is required. In this embodiment, the wire passage 101 is formed on the first assembly 1, and a second pressure rib 201 is provided on the second assembly 2. The second pressure rib 201 is integrally formed with the second assembly 2. Compared with the related technology, this can reduce the assembly process and parts.
[0078] In one specific embodiment, both the first assembly 1 and the second assembly 2 are plastic parts. The first assembly 1 is integrally formed with a wire groove 101, and the second assembly 2 is integrally formed with a second pressure rib 201.
[0079] In one embodiment, the second pressure rib 201 is disposed within the opening of the wire groove 101.
[0080] In this embodiment, since the second pressure rib 201 is located inside the opening of the wire groove 101, the distance between the second pressure rib 201 and the first pressure rib 102 can be further reduced, ensuring that the wire is pressed tightly and that the wire will not come loose when the wire is pulled outside the first assembly 1.
[0081] In one embodiment, the side wall of the first assembly 1 is provided with an inlet 103 communicating with the wire groove 101, and an outlet 104 is provided at the end of the wire groove 101 away from the inlet 103. A wire buckle 105 is provided at the outlet 104 or at a position on the first assembly 1 near the outlet 104.
[0082] In this embodiment, the wire can be pre-fixed by setting a wire clip 105 at the outlet 104 or at a position on the first assembly 1 near the outlet 104.
[0083] Specifically, during assembly, the wire enters the wire groove 101 through the inlet 103 and exits the wire groove 101, where it is secured by the wire clip 105 to ensure that the wire does not come out of the wire groove 101. The wire passes through the outlet 104 and connects to the electrical components inside the first assembly 1. Then, the second assembly 2 is installed. The second assembly 2 cooperates with the first assembly 1 to press the wire tightly into the wire groove 101. The wire is fixed by the second assembly 2 and the first assembly 1. Compared with related technologies, there is no need to set up an additional pressure plate, which reduces the number of parts and assembly steps, and also reduces the space occupied.
[0084] In one specific embodiment, the wire clip 105 is located on the first assembly 1 near the wire outlet 104.
[0085] Specifically in one embodiment, such as Figure 5 As shown, the first assembly 1 has a through hole 107 surrounding the screw post 301, the wire groove 101 is a semi-circular shape surrounding the through hole 107, and the wire buckle 105 extends horizontally from the top of the outer wall of the through hole 107. Therefore, when the wire is led out from the wire groove 101, the wire buckle 105 is located above the wire.
[0086] Specifically in one embodiment, such as Figure 5 As shown, a hole 106 is provided below the wire buckle 105. The function of the hole 106 is to facilitate the demolding of the wire buckle 105.
[0087] In one specific embodiment, the outer wall of the through hole 107 forms the first side wall of the wire groove 101. The wire groove 101 has a second side wall opposite to the first side wall. The wire outlet 104 is opened at the end of the second side wall. The wire buckle 105 can fix the wire at the bend from the wire groove 101 to the wire outlet 104.
[0088] In one specific embodiment, the second sidewall adjacent to the outlet 104 is an arc surface to prevent the wire from bending and causing wear.
[0089] In one specific embodiment, the first assembly 1 includes an annular sidewall and a bottom annular mounting plate. The wire groove 101 is disposed on the bottom annular mounting plate. One side of the wire outlet 104 is adjacent to the second sidewall, and the other side is located on the inner edge of the bottom annular mounting plate, which facilitates the routing of wires.
[0090] In one embodiment, the second assembly is provided with a groove 202 for receiving the wire groove 101.
[0091] In this embodiment, by providing a groove 202 in the second assembly 2, the wire groove 101 is accommodated in the groove 202, which can make the connection between the second assembly 2 and the first assembly 1 tighter.
[0092] According to an embodiment of the present invention, in a second aspect, a base assembly is also provided, including the wire fixing assembly provided in the above embodiment and a fixing frame 3, wherein the fixing frame 3 passes through the first mounting part 1 and is fixedly connected to the second mounting part 2.
[0093] In this embodiment, the first assembly 1 has a wire groove 101, and the fixing bracket 3 is located inside the first assembly 1. The wire portion is located inside the wire groove 101. The fixing bracket 3 passes through the first assembly 1 and is connected to the second assembly 2 by screws 4. After the second assembly 2 is fixed to the fixing bracket 3, the second assembly 2 and the first assembly 1 are relatively fixed. The second assembly 2 and the first assembly 1 cooperate to press the wire tightly into the wire groove 101. The wire is fixed by the second assembly 2 and the first assembly 1. Compared with related technologies, there is no need to set up an additional pressure plate, which reduces the number of parts and assembly processes, and also reduces the space occupied. In addition, since the interference of the wire caused by the pressure of the first assembly 1 and the second assembly 2 is between 1.05mm and 1.95mm, it can avoid the wire being subjected to excessive interference, which would lead to excessive deformation of the insulation layer and thus the risk of insulation layer failure and leakage after long-term operation. At the same time, it can ensure that the wire fixing effect meets the standard requirements.
[0094] In one embodiment, the mounting bracket 3 is provided with either a screw post 301 or a screw hole, the second assembly 2 is provided with either a screw post 301 or a screw hole, and the first assembly 1 is provided with a through hole 107 through which the screw post 301 passes, and a wire groove 101 surrounds the through hole 107.
[0095] In this embodiment, the fixing bracket 3 is provided with one of the screw post 301 or the screw hole, the second assembly 2 is provided with the other of the screw post 301 or the screw hole, and the first assembly 1 is provided with a through hole 107 for the screw post 301 to pass through. The wire groove 101 surrounds the through hole 107, so the wire groove 101 surrounds the screw post 301. The entire wire groove 101 has a large length, which increases the contact area with the wire. At the same time, the screw post 301 can provide support when the wire is under tension. The structural strength of the screw post 301 itself can be used to prevent the wire from being pulled out directly.
[0096] In one embodiment, the mounting bracket 3 is provided with a screw post 301 and the second assembly 2 is provided with a screw hole. During assembly, after aligning the screw hole on the second assembly 2 with the screw post 301 on the mounting bracket 3, the screw 4 is passed through the screw hole and tightened in the screw post 301.
[0097] In one embodiment, the screw post 301 abuts against the outer wall of the groove 101.
[0098] In this embodiment, since the screw post 301 abuts against the outer wall of the wire groove 101, the wire groove 101 can be prevented from deforming. In particular, when the wire is under tension, the screw post 301 can provide support for the wire groove 101 when the wire is under tension, thus preventing the wire groove 101 from deforming.
[0099] In one specific embodiment, the side wall of the first assembly 1 is provided with an inlet 103 communicating with the wire groove 101. The end of the wire groove 101 away from the inlet 103 is the outlet 104. A wire buckle 105 is provided at the outlet 104. The fixing bracket 3 is provided with a screw post 301. The second assembly 2 is provided with a screw hole. The first assembly 1 is provided with a through hole 107 for the screw post 301 to pass through. The wire groove 101 surrounds the through hole 107. The wire buckle 105 extends horizontally from the top of the outer wall of the through hole 107.
[0100] Specifically in one embodiment, such as Figure 3 As shown, the base assembly also includes a support ring assembly 5. The support ring assembly 5 and the fixing frame 3 are fixedly connected as a whole. The first mounting part 1 and the support ring assembly 5 are fixedly connected as a whole by a hook. When the second mounting part 2 is connected to the fixing frame 3, the outer edge of the second mounting part 2 presses against the first mounting part 1.
[0101] In one specific embodiment, the base assembly has a heating function, and a heating plate can be installed inside the fixing frame 3.
[0102] In one specific embodiment, the base assembly can be used for rice cookers, electric kettles, induction cookers, etc.
[0103] According to an embodiment of the present invention, in a third aspect, a household appliance is also provided, including the base assembly provided in the above embodiments.
[0104] This household appliance features a wire trough 101 in either the second assembly 2 or the first assembly 1. A fixing bracket is located inside the first assembly 1, and the wire portion is housed within the wire trough 101. The fixing bracket passes through the first assembly 1 and is connected to the second assembly 2 via screws 4. After the second assembly 2 is fixed to the fixing bracket, it is relatively fixed to the first assembly 1. The second assembly 2 and the first assembly 1 work together to press the wire tightly into the wire trough 101. By using the second assembly 2 and the first assembly 1 to fix the wire, compared with related technologies, no additional pressure plate is required, reducing the number of parts and assembly steps, and also reducing the space occupied. In addition, since the interference of the wire caused by the pressure of the first assembly 1 and the second assembly 2 is between 1.05mm and 1.95mm, it can avoid excessive interference of the wire, which could lead to excessive deformation of the insulation layer and the risk of insulation failure and leakage after long-term operation. At the same time, it can ensure that the wire fixing effect meets the standard requirements.
[0105] In one specific embodiment, the household 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.
