Abstract
Description
Technical Field
[0001] The present application relates to the technical field of kitchen appliances, and in particular to a cooking appliance. Background Art
[0002] Most cooking appliances feature a control panel for human-computer interaction. This control panel typically consists of a bracket, a circuit board, and a panel. To assemble the panel to the main unit, the circuit board must first be screwed to the bracket, then the bracket to the main unit. Finally, the panel cover is placed on the outside of the bracket and secured to the main unit with adhesive, clips, or screws. While this arrangement ensures a secure fit of the control panel to the main unit, it is inconvenient to disassemble and assemble, and can easily damage the circuit board within the control panel. Utility Model Content
[0003] Based on this, it is necessary to provide a cooking appliance that is not only convenient for disassembly and assembly of the control panel assembly, but also improves the problem of poor contact and easy damage of the circuit board.
[0004] The present application provides a cooking appliance, comprising a main unit assembly and a control panel assembly; the control panel assembly comprises a panel, a sensing film, a bracket and a circuit board stacked in sequence; the panel is provided with a connecting portion on the side facing the sensing film, and at least the bracket and the circuit board are provided with through holes respectively; the control panel assembly further comprises fasteners, which pass through each of the through holes and are connected to the connecting portion, and the panel is connected to the main unit assembly.
[0005] It can be understood that the present application is connected to the connecting portion on the panel by fasteners passing through the through holes on the circuit board and the through holes on the bracket. With such a setting, on the one hand, the fasteners can be used to cooperate with the various through holes to position and assemble the circuit board and the bracket; on the other hand, the circuit board, bracket, sensing film and panel can be locked by the connection between the fasteners and the connecting portion, so that the four are connected into an integral structure, which is convenient for disassembly and assembly of the integral structure relative to the host assembly. In this process, whether it is disassembly or installation, only one connection between the fasteners and the connecting portion is required, which simplifies the disassembly and assembly process and makes the operation more convenient; and, such a setting avoids the deformation problem of the bracket caused by multiple forces as much as possible, ensures that the force on the circuit board is basically balanced, and improves the problem of easy damage to the circuit board. At the same time, such a setting reduces assembly errors, thereby improving the problem of poor contact of the circuit board due to cumulative errors, and further improves the problem of easy damage to the circuit board.
[0006] In some embodiments, the connecting portion is a connecting post protruding from the panel, and the connecting post is at least passed through the corresponding through hole of the bracket. In this way, the matching of the connecting post and the bracket can be utilized to ensure the installation and positioning of the bracket relative to the panel.
[0007] In some embodiments, the through-hole of the bracket is a first through-hole, and the connecting post does not protrude from the side of the first through-hole facing the circuit board. This arrangement, on the one hand, ensures that the bracket can be fastened between the circuit board and the panel, improving the bracket's installation stability; on the other hand, the sensing film is pressed between the bracket and the panel by the connection between the fastener and the connecting post, ensuring a tight fit with the panel.
[0008] In some embodiments, the through hole of the bracket is a first through hole, the bracket includes a base plate and a light shield disposed on the base plate, the light shield extends through the base plate along its thickness, the base plate is provided with a mounting post, and the first through hole extends through the mounting post and the base plate. This arrangement ensures that the bracket and the connecting post cooperate, while preventing the connecting post from interfering with the light beads within the light shield.
[0009] In some embodiments, one of the bracket and the circuit board has a protruding positioning post, and the other has a positioning hole, into which the positioning post is inserted. This arrangement allows the circuit board to be positioned relative to the bracket and ensures that each lamp bead on the circuit board can extend into its corresponding light shield.
[0010] In some embodiments, the main unit assembly is configured with an assembly cavity, and at least a portion of the control panel assembly is accommodated in the assembly cavity. This can prevent the control panel assembly from protruding too much relative to the main unit assembly, thereby improving installation reliability and safety in use.
[0011] In some embodiments, one of the edge of the cavity opening and the edge of the panel is provided with a recessed mounting groove, and the other is provided with a protruding mounting protrusion, which is inserted into the mounting groove. This improves the sealing and waterproof properties of the connection between the control panel assembly and the host assembly.
[0012] In some embodiments, the assembly groove is provided at the edge of the cavity opening of the assembly cavity, and a drainage hole is provided in the assembly groove, so that water is guided to be discharged from the drainage hole by the assembly groove, thereby improving the waterproof performance.
[0013] In some embodiments, the assembly cavity is tilted, and the drainage hole is located at the lowest point of the assembly groove in the vertical direction, thereby improving the diversion effect and facilitating more adequate drainage.
[0014] In some embodiments, the main unit assembly includes an enclosure shell and a partition connected to the side wall of the enclosure shell, the enclosure shell and the partition together enclose the assembly cavity, and the assembly groove and the drainage hole are both provided in the enclosure shell; the enclosure shell and the partition together enclose a bearing cavity on the side facing away from the assembly cavity, the drainage hole is connected to the bearing cavity, and the enclosure shell is constructed with a water outlet connecting the bearing cavity and the external environment.
[0015] The liquid diverted to the drain hole via the assembly groove flows into the bearing cavity through the drain hole, and then flows out along the water outlet hole, so as to minimize the impact of the liquid on the electrical structure and the control panel assembly in the bearing cavity.
[0016] In some of these embodiments, the enclosing housing is provided with a support frame in the bearing cavity. The support frame is elevated relative to the bottom wall of the enclosing housing and is used to support the electrical structure. The water outlet hole is located below the support frame. Such an arrangement can ensure as much as possible that the liquid flowing into the bearing cavity through the drain hole does not come into contact with the electrical structure.
[0017] In some of these embodiments, the main body assembly includes a control part and a cup part connected to the control part. The two are arranged horizontally. The control part is used to install the control panel assembly and the electrical structure, and the cup part is used to connect the cup body. In this way, the cup part can be separated from the electrical structure and the control panel assembly, improving the use safety. Description of the Drawings

Detailed Description of the Embodiment
[0030] In order to make the above objects, features and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.
[0031] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it can be directly on the other component or there can also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of the present application are only for the purpose of illustration and do not represent the only implementation manner.
[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0033] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first feature is in direct contact with the second feature, or the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.
[0034] Unless otherwise defined, all technical and scientific terms used in the description of this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0035] In the related art, most cooking appliances are provided with a control panel for human-machine interaction. The control panel generally includes a bracket, a circuit board and a panel. When assembling the control panel relative to the main body, it is necessary to first fix the circuit board to the bracket with screws, then fix the bracket to the main body with screws, and finally cover the panel on the outside of the bracket and fix it to the main body by adhesion, snap fit or screws.
[0036] In this process, the bracket not only needs to bear the force of screwing and fixing the circuit board, but also needs to bear the force of screwing and fixing the main body. Considering the manufacturing errors and assembly errors existing in machining, the above two forces may restrict each other, causing the bracket to be unevenly stressed and prone to problems such as deformation, which may lead to uneven stress on the circuit board and easy damage. Moreover, the assembly errors between the bracket and the circuit board, as well as the cumulative assembly errors between the bracket and the main body components, result in a relatively large overall assembly error, and there may be problems with poor contact of the circuit board. At this time, the user may need to press the panel more forcefully, which is also likely to cause damage to the circuit board. In addition, if the circuit board is damaged, it is necessary to first disassemble the panel relative to the main body, then disassemble the bracket relative to the main body, and then disassemble the circuit board relative to the bracket. Thus, the overall disassembly and assembly process is complicated and inconvenient to operate.
[0037] Based on this, please refer to Figures 1 to 5One embodiment of the present application provides a cooking appliance, comprising a main unit assembly 10 and a control panel assembly 20. The control panel assembly 20 comprises a panel 21, a sensing membrane 22, a bracket 23, and a circuit board 24, which are stacked in sequence. The panel 21 is provided with a connecting portion 211 on the side facing the sensing membrane 22, and at least the bracket 23 and the circuit board 24 are provided with corresponding through holes. The control panel assembly 20 further comprises a fastener 25, which passes through each through hole and is connected to the connecting portion 211. The panel 21 is connected to the main unit assembly 10. The bracket 23 corresponds to the first through hole 2301, and the circuit board 24 corresponds to the second through hole 2401.
[0038] It can be understood that the fastener 25 is sequentially passed through the second through hole 2401 of the circuit board 24 and the first through hole 2301 of the bracket 23 to connect with the connecting portion 211, thereby locking the circuit board 24, the bracket 23 and the sensing membrane 22 relative to the panel 21, so that the four are connected into an integral structure, which is convenient for disassembly and assembly of the integral structure relative to the host assembly 10. In this process, whether it is disassembly or installation, only a single connection between the fastener 25 and the connecting portion 211 is required to achieve the overall assembly of the aforementioned four, simplifying the disassembly and assembly process and making the operation more convenient. In addition, such a setting avoids the deformation problem of the bracket 23 caused by multiple forces as much as possible, ensures that the force on the circuit board 24 is basically balanced, and improves the problem of easy damage to the circuit board 24. At the same time, such a setting reduces assembly errors, thereby improving the problem of poor contact of the circuit board 24 due to cumulative errors, and further improves the problem of easy damage to the circuit board 24.
[0039] The panel 21 is typically made of resin, which facilitates the manufacture of the connection portion 211. The connection portion 211 and the panel 21 can be integrally formed, for example, by injection molding. Alternatively, the panel 21 can be injection molded and then the connection portion 211 can be machined and formed. This is merely an example.
[0040] See also Figures 2 to 5 Furthermore, the sensing membrane 22 also has a through hole corresponding to the third through hole 2201. The fastener 25 sequentially passes through the second through hole 2401, the first through hole 2301, and the third through hole 2201 to connect to the connecting portion 211. Of course, the sensing membrane 22 can also be smaller in size, in which case the sensing membrane 22 does not need to have the third through hole 2201. This is merely an example.
[0041] In actual use, after the fastener 25 is connected to the connecting portion 211, the sensing film 22 can be pressed between the bracket 23 and the panel 21. Under the action of the fastener 25, the sensing film 22 is tightly attached to the inner side of the panel 21 (i.e., the side of the panel 21 facing the circuit board 24), facilitating user touch operation. Alternatively, the sensing film 22 can be directly bonded to the side of the panel 21 facing the bracket 23 to facilitate human-computer interaction. Alternatively, the sensing film 22 can be bonded to the bracket 23, and the bracket 23 is pressed against the panel 21 under the action of the fastener 25.
[0042] The third through hole 2201, the first through hole 2301, and the second through hole 2401 are arranged correspondingly. When multiple fasteners 25 are used for fastening, the multiple fasteners 25 are arranged at intervals along the circumference of the panel 21. Each fastener 25 corresponds to a group of the second through hole 2401, the first through hole 2301, and the third through hole 2201, and corresponds to one connecting portion 211. The third through hole 2201, the first through hole 2301, and the second through hole 2401 can be coaxially arranged.
[0043] See also Figures 3 to 5 For example, the connecting portion 211 is a connecting post 2111 protruding from the panel 21. The connecting post 2111 is inserted through at least the corresponding first through-hole 2301 of the bracket 23. In other words, the connecting post 2111 on the panel 21 is inserted through the first through-hole 2301 on the bracket 23 to position and assemble the bracket 23 relative to the panel 21. The fastener 25 can pass through the second through-hole 2401 on the circuit board 24 to connect with the connecting post 2111. This arrangement can appropriately reduce the length of the fastener 25, that is, shorten the lever arm, and improve the connection reliability of the fastener 25.
[0044] like Figure 3 and Figure 5 As shown, in some specific embodiments, the connecting post 2111 is configured with a threaded hole 2112. The fastener 25 includes a threaded section and a nut 251. The threaded section is threadedly connected to the connecting post 2111, so that the nut 251 presses against the side of the circuit board 24 facing away from the panel 21, thereby assembling the circuit board 24, the bracket 23, the sensing film 22, and the panel 21.
[0045] Alternatively, the connection portion 211 may also be a threaded hole. That is, the panel 21 may directly have a threaded hole to be threadedly connected to the fastener 25. Alternatively, the connection portion 211 may also be a glue-dispensing protrusion, and the fastener 25 passes through the three through holes in sequence and then adheres to the glue-dispensing protrusion to achieve fixation. Another alternative is that the connection portion 211 may also be a card hole, and the fastener 25 passes through the three through holes and then snaps into engagement with the card hole. For example, the snap-in engagement can be achieved by using the engagement of the protrusion and the groove. This is just an example, and it is sufficient as long as the fastener 25 can cooperate with the connection portion 211 to connect the control panel assembly 20 into an integral structure.
[0046] The following description takes the connecting portion 211 as a connecting post 2111 as an example.
[0047] like Figure 2 and Figure 3 As shown, in actual use, the bracket 23 is used to support the circuit board 24. The circuit board 24 is provided with lamp beads 241, which are electrically connected to the sensing film 22. The lamp beads 241 can illuminate the panel 21. The bracket 23 includes a base plate 231 and a light shield 232 provided on the base plate 231. The light shield 232 extends through the thickness of the base plate 231. The light shield 232 is provided outside the lamp beads 241 to focus light. Multiple lamp beads 241 are provided and arranged in intervals, and each lamp bead 241 corresponds to a light shield 232.
[0048] Furthermore, the base plate 231 is provided with a mounting post 233, and the first through hole 2301 is provided through the mounting post 233 and the base plate 231. Such a configuration not only satisfies the cooperation between the bracket 23 and the connecting post 2111, but also prevents the connecting post 2111 from interfering with the lamp beads 241 in the light shield 232.
[0049] Please continue reading Figures 2 to 5 In some specific embodiments, the mounting post 233 protrudes from the side of the base plate 231 facing the light shield 232, allowing the side of the bracket 23 facing the sensing membrane 22 to be as flat as possible, thereby improving the pressing effect and reducing stress concentration on the sensing membrane 22. Furthermore, because the light shield 232 protrudes relative to the base plate 231, the mounting post 233 compensates for the size difference between the base plate 231 and the light shield 232. This ensures that when the nut 251 of the fastener 25 presses against the circuit board 24, the circuit board 24 and the mounting post 233 are pressed against the side facing away from the base plate 231, thereby improving installation stability and connection reliability.
[0050] The diameter of the first through hole 2301 may be slightly larger than the outer diameter of the connecting post 2111 , so as to facilitate the connection post 2111 to pass through the first through hole 2301 .
[0051] See also Figure 5, Exemplarily, the connecting post 2111 does not protrude from the side of the first through hole 2301 facing the circuit board 24, that is, the connecting post 2111 does not protrude from the side of the mounting post 233 facing the circuit board 24. At this time, the connecting post 2111 only sequentially passes through the third through hole 2201 and the first through hole 2301. Such a setting, on the one hand, ensures that the bracket 23 can be fastened between the circuit board 24 and the panel 21, improving the installation stability of the bracket 23; on the other hand, relying on the connection between the fastener 25 and the connecting post 2111, the sensing film 22 is pressed between the bracket 23 and the panel 21 to ensure close fit with the panel 21. If the connecting post 2111 protrudes from the first through hole 2301, after the fastener 25 passes through the circuit board 24 and is connected to the connecting post 2111, there is a gap between the circuit board 24 and the bracket 23, and the bracket 23 can move along the axial direction of the connecting post 2111, which not only causes the sensing film 22 and the panel 21 to not fit closely, but also easily damages the circuit board 24. Therefore, in this embodiment, the connecting post 2111 does not protrude from the first through hole 2301 to promote the compact connection between the circuit board 24, the bracket 23, the sensing film 22 and the panel 21 under the action of the fastener 25, meeting the setting requirements of stable assembly and close fit.
[0052] Further, the end of the connecting post 2111 facing away from the panel 21 may be located within the first through hole 2301 or may be flush with the end of the mounting post 233 facing the circuit board 24, as long as it is ensured that the connecting post 2111 does not protrude from the first through hole 2301.
[0053] As Figure 5 shown, in some embodiments, under the action of the fastener 25, the circuit board 24 is pressed against the end face of the bracket 23 on the side of the first through hole 2301 facing away from the panel 21, that is, the circuit board 24 is pressed against the end face of the mounting post 233 facing away from the substrate 231 to ensure that the sensing film 22 is closely attached to the panel 21. The gap between the end face of the connecting post 2111 facing away from the panel 21 and the circuit board 24 is greater than or equal to 0.1 mm. Such a setting ensures that when the circuit board 24 is pressed against the end face of the mounting post 233, it does not need to be in contact with the connecting post 2111 to be stressed, promoting the closer fit of the sensing film 22 and the panel 21.
[0054] Further, the gap between the end face of the connecting post 2111 facing away from the panel 21 and the circuit board 24 is less than or equal to 0.3 mm. Such a setting ensures that the connecting post 2111 itself has sufficient length to fully cooperate with the fastener 25 and improve the connection reliability.
[0055] During actual assembly, when the fastener 25 is tightened against the connecting post 2111, a pulling force is applied to the connecting post 2111 toward the circuit board 24. Since the panel 21 is mostly made of resin material, it is easily deformed under the action of tension. Therefore, if the connecting post 2111 is too long, when the same type of fastener 25 is tightened to press the nut 251 against the circuit board 24, the contact area between the fastener 25 and the connecting post 2111 will increase. The tension applied to the panel 21 by the connecting post 2111 will be too great, which can easily cause the panel 21 to deform. However, if the length of the connecting post 2111 is too short, the contact area with the fastener 25 will be small, which can easily lead to the problem of reduced connection tightness. Therefore, the length of the connecting post 2111 should not be too long or too short. Therefore, the above-mentioned configuration can ensure that when the connecting post 2111 and the fastener 25 are matched, not only the deformation of the panel 21 caused by the tension is reduced, but also the tight fit of the sensing film 22 to the panel 21 is ensured.
[0056] In some specific embodiments, the gap between the end surface of the connecting post 2111 facing away from the panel 21 and the circuit board 24 is 0.1 mm, 0.15 mm, 0.2 mm, 0.26 mm, 0.28 mm or 0.3 mm.
[0057] Alternatively, the connecting post 2111 may pass through the third through hole 2201 and the first through hole 2301 in sequence, and then pass through the second through hole 2401. In this case, the connecting post 2111 does not protrude from the side of the second through hole 2401 facing away from the panel 21. The fastener 25 is threadedly connected to the connecting post 2111, and the end of the fastener 25 facing away from the panel 21 is pressed against the circuit board 24 to ensure that the sensing film 22 can be pressed between the bracket 23 and the panel 21.
[0058] Please continue reading Figures 2 to 5 In an optional embodiment, one of the bracket 23 and the circuit board 24 is provided with a protruding positioning hole 262, while the other is provided with a protruding positioning hole 262, and the positioning post 261 is inserted into the positioning hole 262. This arrangement realizes the positioning and assembly of the circuit board 24 relative to the bracket 23, ensuring that each lamp bead 241 on the circuit board 24 can extend into the corresponding light shield 232. In actual use, with respect to the bracket 23, the light shield 232 is protruding from the side of the base plate 231 facing the circuit board 24, and the positioning post 261 is protruding from the side of the base plate 231 facing the circuit board 24. The positioning hole 262 is provided through the circuit board 24 along the thickness direction of the circuit board 24. The protruding length of the positioning post 261 relative to the base plate 231 is greater than the protruding length of the light shield 232 relative to the base plate 231, so that it preferentially engages with the positioning hole 262 to achieve positioning.
[0059] The diameter of the positioning post 261 can be smaller than the diameter of the mounting post 233, and can even be smaller than the diameter of the first through hole 2301. In some specific embodiments, the diameter of the first through hole 2301 can be 1.2 mm, and the diameter of the positioning post 261 can be 1 mm. This is merely an example.
[0060] In another alternative embodiment, the positioning post 261 may be protruding from the light shield 232, as long as the positioning post 261 preferentially engages with the positioning hole 262 for positioning. Furthermore, the side of the positioning post 261 facing away from the substrate 231 may extend out of the positioning hole 262, or it may be located within the positioning hole 262, for example, flush with the positioning hole 262. This is merely an example. Furthermore, the positioning hole 262 may be a blind hole recessed along the thickness of the circuit board 24, as long as the positioning post 261 preferentially engages with the positioning hole 262.
[0061] In other embodiments, the positioning hole 262 may be provided on the base plate 231 and the positioning post 261 may be provided on the circuit board 24. In this case, the side of the positioning post 261 facing away from the circuit board 24 does not protrude from the side of the positioning hole 262 facing the panel 21, thereby avoiding interference with the pressing of the circuit board 24 relative to the bracket 23 and affecting the tightness of the fit between the sensing film 22 and the panel 21.
[0062] like Figure 1 、 Figure 6 、 Figure 7 and Figure 10 As shown, in some embodiments, the host assembly 10 is configured with an assembly cavity 101, and at least a portion of the control panel assembly 20 is accommodated in the assembly cavity 101. In this way, the control panel assembly 20 does not protrude too much relative to the host assembly 10, thereby improving installation reliability and safety in use.
[0063] In actual use, the main unit assembly 10 has a control unit 1001 and a cup unit 1002 connected to the control unit 1001, and the two are arranged in a horizontal direction. The control unit 1001 is used to install the control panel assembly 20 and the electrical structure 14, that is, the assembly cavity 101 is provided in the control unit 1001. The electrical structure 14 is electrically connected to the control panel assembly 20 to enable the use of the cooking utensil. The cup unit 1002 is used to connect the cup body. The cup body can be detachably connected to the cup unit 1002, which is convenient for taking and placing food ingredients, and is also convenient for replacing different cup bodies to achieve multiple uses of one item. Such a setting can separate the electrical structure 14 and the control panel assembly 20 relative to the cup unit 1002 and the cup body, thereby improving safety in use.
[0064] See also Figure 1 and 5 、 Figure 7 、 Figure 8 and Figure 9, in some embodiments, the panel 21 in the control panel assembly 20 is snap-connected to the control part 1001 of the host component 10, facilitating the disassembly and assembly of the two. For example, one of the panel 21 and the control part 1001 is provided with a snap projection 42, and the other is provided with a snap arm 41, and the snap arm 41 is configured with a snap hole 4101, and the snap projection 42 is snap-fitted with the snap hole 4101 to achieve assembly. In some embodiments, the cavity wall of the assembly cavity 101 is provided with a snap projection 42, and the snap arm 41 is convexly provided on the side of the panel 21 facing the circuit board 24. The protruding length of the snap arm 41 is relatively large, facilitating the snap arm 41 to preferentially extend into the assembly cavity 101 and be snap-fitted with the snap projection 42. The number of snap arms 41 is multiple and is circumferentially and evenly spaced around the panel 21, and each snap arm 41 corresponds to a snap projection 42. For example, there are 8 snap arms 41 corresponding to 8 snap projections 42.
[0065] As Figure 1 and Figure 10 shown, in order to improve the assembly stability, the control part 1001 is provided with a support platform 19 at the cavity opening of the assembly cavity 101, and the support platform 19 is configured with an avoidance hole 1901 for the snap arm 41 to pass through.
[0066] Alternatively, it can also be that the snap arm 41 is provided on the cavity wall of the assembly cavity 101, the snap projection 42 is convexly provided on the panel 21, and the snap arm 41 passes through the aforementioned avoidance hole 1901 and extends out of the cavity opening of the assembly cavity 101, facilitating the snap-fitting with the snap projection 42.
[0067] Please refer to Figure 1 and Figure 6 shown, in an alternative embodiment, the distance a between the outermost contour line of the control part 1001 and the outermost contour line of the control panel assembly 20 is between 0.3 mm and 0.5 mm. The outermost contour line is the outer boundary line. Such a setting ensures that there is no particularly obvious stepped shape between the control panel assembly 20 and the control part 1001 after assembly, and visually forms an integral structure as much as possible, improving the aesthetics. In some specific embodiments, the distance a between the outermost contour line of the control part 1001 and the outermost contour line of the control panel assembly 20 can be 0.3 mm, 0.325 mm, 0.37 mm, 0.42 mm, 0.48 mm or 0.5 mm.
[0068] As Figure 6 and Figure 7As shown, further, the edge of the assembly cavity 101 and the outer peripheral surface of the control unit 1001 are transitioned through a fillet 105, and the radius of the fillet 105 is between 0.1mm and 0.5mm. This arrangement ensures a smooth and rounded transition between the control unit 1001 and the edge of the assembly cavity 101, which makes the visual connection between the two smoother after the control panel assembly 20 is assembled. For example, the radius of the fillet 105 is 0.1mm, 0.23mm, 0.28mm, 0.32mm, 0.45mm, or 0.5mm.
[0069] Furthermore, the assembly cavity 101 is arranged at an angle, and the control panel assembly 20 is also assembled at an angle, so that the user can observe the information displayed on the panel 21 more easily.
[0070] like Figure 5 、 Figure 7 、 Figure 9 and Figure 10 As shown, the panel 21 is provided with an assembly reference surface 213 on the side facing the main assembly 10, so as to be adapted to the edge of the cavity opening of the aforementioned assembly cavity 101. Figure 5 As shown, the panel 21 has a rounded corner 212 at its edge. The angle α between the tangent of the rounded corner 212 and the assembly reference surface 213 is acute. For example, the angle between the tangent of the rounded corner 212 and the assembly reference surface 213 can be 40 degrees, 46 degrees, 50 degrees, 54 degrees, or 60 degrees, etc. This arrangement facilitates a smoother transition between the control panel assembly 20 and the main unit assembly 10, visually forming a substantially continuous transitional curved surface. The aforementioned assembly reference surface 213 is a flat surface.
[0071] See also Figure 5 、 Figure 7 、 Figure 8 and Figure 9 For example, one of the edge of the cavity opening of the assembly cavity 101 and the edge of the panel 21 is provided with a recessed assembly groove 31, and the other is provided with a protrusion 32, which is inserted into the assembly groove 31. The assembly groove 31 and the assembly protrusion 32 are both arranged around the circumference of the assembly cavity 101. It can be understood that the arrangement of the assembly protrusion 32 and the assembly groove 31 mainly achieves waterproof and sealing effects, thereby preventing moisture from affecting the circuit board 24 and the sensor membrane 22 in the control panel assembly 20 as much as possible. The assembly protrusion 32 can be embedded in the assembly groove 31 to minimize the gap at the assembly point.
[0072] Further, the protruding length of the assembly protrusion 32 is between 1.5 mm and 2 mm. It can be understood that the length of the assembly protrusion 32 should not be too long or too short. If it is too long, the depth of the corresponding assembly groove 31 needs to be relatively large, which may weaken the structural strength at the mating part and the structural strength at the location where the assembly groove 31 is provided; of course, if it is too small, the sealing and waterproof effects will be weakened. In some specific embodiments, the protruding length of the assembly protrusion 32 is 1.5 mm, 1.6 mm, 1.75 mm, 1.85 mm, 1.9 mm or 2 mm. In this way, the requirements for structural strength and the requirements for sealing and waterproofing can be compatible.
[0073] In some embodiments, the assembly groove 31 is provided at the edge of the cavity opening of the assembly cavity 101, and the assembly protrusion 32 protrudes from the side of the panel 21 facing the circuit board 24. When the assembly protrusion 32 is inserted into the assembly groove 31 and the panel 21 is fastened to the host assembly 10, the assembly reference surface 213 on the panel 21 is adapted to the edge of the slot opening of the assembly groove 31. At this time, the setting of the assembly protrusion 32 also has the effect of increasing the structural strength of the edge of the panel 21; moreover, the assembly groove 31 can also play a role in drainage. Specifically, a drain hole 103 is provided in the assembly groove 31. If the water flowing onto the panel 21 can be guided along the rounded corner 212 to the assembly groove 31 and discharged through the drain hole 103.
[0074] As Figure 8 shown, further, if the assembly cavity 101 is arranged obliquely, the drain hole 103 is located at the lowest point of the assembly groove 31 in the vertical direction, which is convenient for sufficient drainage. Among them, multiple drain holes 103 arranged at intervals or one drain hole 103 can be provided at the lowest part of the assembly groove 31.
[0075] As Figure 7 、 Figure 8 and Figure 10 shown, in actual use, the host assembly 10 includes an enclosing housing 11 and a partition 12 connected to the inner side wall of the enclosing housing 11. The enclosing housing 11 and the partition 12 jointly enclose an assembly cavity 101, and both the assembly groove 31 and the drain hole 103 are provided on the enclosing housing 11. At the same time, a bearing cavity 102 is jointly enclosed on the side of the enclosing housing 11 and the partition 12 facing away from the assembly cavity 101. The drain hole 103 is communicated with the bearing cavity 102, and the enclosing housing 11 is configured with a water outlet hole (not shown in the figure) communicating the bearing cavity 102 and the external environment. Among them, an electrical structure 14 is installed in the bearing cavity 102, and the electrical structure 14 is electrically connected to the control panel assembly 20. Therefore, the liquid guided to the drain hole 103 through the assembly groove 31 flows from the drain hole 103 into the bearing cavity 102, and then flows out along the water outlet hole, minimizing the influence of the liquid on the electrical structure 14 and the control panel assembly 20 in the bearing cavity 102.
[0076] Further, a support frame 13 is provided in the bearing cavity 102 of the enclosure housing 11. The support frame 13 is elevated relative to the bottom wall of the enclosure housing 11 and is used to support the electrical structure 14. The water outlet hole is located below the support frame 13. For example, the water outlet hole is located in the bottom wall of the enclosure housing 11. Such an arrangement can ensure as much as possible that the liquid flowing into the bearing cavity 102 through the drain hole 103 does not come into contact with the electrical structure 14. Alternatively, the drain hole 103 can directly penetrate to the outside of the enclosure housing 11 to directly divert the liquid to the outside of the main machine assembly 10.
[0077] As Figure 10 shown, specifically, the electrical structure 14 includes a power supply box 141 and a power supply circuit board 142 electrically connected to the power supply box 141. The power supply circuit board 142 can be supported on the support frame 13. The support frame 13 can include a support plate and a plurality of support columns connected to the support plate. Each support column is evenly spaced along the circumferential direction of the support plate and is connected to the bottom wall of the enclosure housing 11. The power supply circuit board 142 is supported on the support plate, and the power supply box 141 is arranged above the power supply circuit board 142. The power cord 143 is connected to the power supply box 141 and can extend to the outside of the enclosure housing 11 for connecting to a power supply. The power supply circuit board 142 is electrically connected to the circuit board 24 in the control panel assembly 20. Among them, the foregoing partition 12 is configured with a through hole communicating the assembly cavity 101 and the bearing cavity 102, which can guide the connecting wire for the electrical connection between the power supply circuit board 142 and the control panel assembly 20.
[0078] Still further, the electrical structure 14 further includes a communication circuit board 144 and a communication support 145. The communication support 145 can be directly fixed to the enclosure housing 11 or fixed to the foregoing support frame 13. The communication circuit board 144 is arranged on the communication support 145 and is electrically connected to the power supply circuit board 142 and the circuit board 24 in the control panel assembly 20 to achieve signal transmission.
[0079] During actual use, the enclosure housing 11 includes an enclosure part 111, a base 112, and a cup part housing 113. The enclosure part 111 and the cup part housing 113 are connected into an integral structure. For example, they can be integrally injection-molded. The base 112 is arranged at the bottom of the enclosure part 111 and the cup part housing 113 and is detachably connected, which is convenient for the disassembly, repair, replacement, etc. of the electrical structure 14. The enclosure part 111 encloses at least part of the foregoing assembly cavity 101 and the bearing cavity 102, thereby defining the control part 1001. The foregoing support frame 13 can be connected to the base 112 and extend into the bearing cavity 102. The cup part housing 113 defines a cup part 1002. A connector 15 and a pull ring 16 connected to the connector 15 are further provided in the cup part housing 113. The base 112 is further connected with a suction cup foot pad 17 through a locking member 18, which is convenient for stable placement. The locking member 18 is a screw. A plurality of suction cup foot pads 17 are arranged at intervals, and each suction cup foot pad 17 corresponds to a locking member 18.
[0080] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
[0081] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
