Detailed ways

In order for those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments.

This embodiment provides a knob assembly, which can be installed quickly and save installation time.

As shown in FIGS. 1-4 , the knob assembly includes a knob 1 and a dial switch 2 , wherein a plurality of elastic buckles 111 are provided on the inner side wall of the knob 1 , and a plurality of elastic buckles 111 are provided on the outer side wall of the dial switch 2 . Each of the latching slots 21 is matched with the elastic buckle 111 , and more than one reference portion 123 is provided on the outer side wall of the knob 1 , and each reference portion 123 is disposed opposite to an elastic buckle 111 . The DIP switch 2 is arranged on the PCB board 5 . When installing the elastic buckle 111 and the card slot 21, it is only necessary to align the reference part 123 with the card slot 21 before installation, and directly press the knob 1 to complete the installation task of the knob assembly. Then, the user needs to turn the knob 1 over to observe the specific position of the elastic buckle, and then align the elastic buckle with the card slot 21 . Thus, the time required for the user to install the knob assembly is saved.

It should be noted that the inner sidewall of the knob 1 has a plurality of elastic buckles 111 uniformly distributed in the circumferential direction, and the outer sidewall of the dial switch 2 has a plurality of card slots 21 uniformly distributed in the circumferential direction (refer to FIG. 5 ). The number of elastic buckles 111 is three in this embodiment, correspondingly, the number of card slots 21 is also three, and the number of reference portions 123 is preferably three in this embodiment, that is, each reference The portion 123 is facing an elastic buckle, and the reference portion 123 is also circumferentially disposed on the outer side wall of the knob 1 . The reference portion 123 may be a groove or a protrusion, as long as the reference portion 123 can be directly opposite to the elastic buckle 111 to achieve the purpose of quickly installing the knob assembly.

As shown in FIGS. 1 and 2 , in this embodiment, the knob 1 includes a working part 11 and a water receiving tray 12 connected to the working part 11 . Since the knob 1 is arranged on the inclined side wall of the household appliance, when the household appliance is a cleaning appliance, water will often flow into the knob assembly and affect the operation of the knob assembly. The water at the bottom of the knob 1 flows into the working part 11 to prevent the water from flowing onto the PCB board 5 .

Specifically, as shown in FIG. 2 , the water receiving tray 12 includes a first water blocking wall 121 and a second water blocking wall 122 , and the first water blocking wall 121 is respectively connected with the second water blocking wall 122 and the working part 11 . The included angle between the second water blocking wall 122 and the first water blocking wall 121 is greater than or equal to 90°. That is, the free end of the second water blocking wall 122 extends in a direction away from the working part 11 . This arrangement can greatly increase the water receiving area of the water receiving tray 12 and improve the waterproofness of the knob 1 . It should be noted that the water-receiving pan 12 and the working part 11 are integrally formed, and this arrangement can ensure that the connection between the water-receiving pan 12 and the working part 11 does not leak water, and there is no need to add a waterproof structure to the connection. The reference portion 123 is disposed on the outer side wall of the second water blocking wall 122 .

As shown in FIG. 2 , the knob assembly further includes a water blocking ring 3 , wherein the water blocking ring 3 is arranged on the housing 4 of the household appliance, and the free end of the water blocking ring 3 extends into the blocking formed by the water receiving tray 12 of the knob 1 . The water tank is suspended in the air, that is, the free end of the water retaining ring 3 is not in contact with the inner side wall of the water retaining tank. The cooperation of the water blocking ring 3 and the water receiving tray 12 can block the water flowing in from the installation hole 41 , so as to prevent the water from flowing out of the water receiving tray 12 or splashing out of the water receiving tray 12 .

This embodiment also provides a household appliance, as shown in FIG. 5 and FIG. 6 , the household appliance includes the knob assembly described above. The household appliance can be a washing machine or a kitchen water heater (ie, kitchen treasure). The household appliance further includes a housing 4, the housing 4 is provided with a mounting hole 41 that can pass through the knob 1, the mounting hole 41 is extended to the inside of the housing 4 with the above-mentioned water retaining ring 3, the knob 1 is perpendicular to the housing 4, but the housing 4 The part of the setting knob 1 is set inclined with respect to the horizontal plane.

Since the part of the housing 4 where the knob 1 is arranged is inclined relative to the horizontal plane, the knob 1 will be in close contact with part of the side wall of the installation hole 41 under the influence of gravity, resulting in a larger gap in other positions, making it easier for water to flow into the installation hole In 41, in order to solve the above problem, as shown in FIG. 5, the housing 4 also includes a plurality of stable protrusions 411 for preventing the knob 1 from shaking; the plurality of stable protrusions 411 are evenly distributed in the installation hole 41 or the water retaining ring 3 in the circumferential direction. on the inner side wall.

A plurality of stabilizing protrusions 411 are evenly arranged on the installation hole 41 or the inner side wall of the water retaining ring 3 in the circumferential direction, so that the knob 1 can be supported by the stabilizing protrusions 411 in the circumferential direction, so that the knob 1 can be kept in the circumferential direction with the installation hole 41. The gap is uniform. Compared with the prior art, the stabilizing protrusion 411 will not cause the gap to be too large to allow external water to enter the mounting hole 41 easily, nor will it affect the rotation of the knob 1 because the gap is too small. It should be noted that the shape of the stabilizing protrusion 411 is not particularly limited in this embodiment, but it should not affect the rotation of the knob 1 .

As shown in FIG. 5 , the household appliance further includes a display screen 7 and a fixed rear shell 6 connected with the outer shell 4, wherein the display screen 7 is pasted or clamped on the end of the knob 1 that does not extend into the outer shell 4, specifically through the double-sided It can be fixed by adhesive or fixed by connecting clips. The display screen 7 mainly displays the brightness, and is used to remind the user that the household appliance is in a power-on state. The fixed rear shell 6 is fixed on the outer shell 4 by screws 8, and the fixed rear shell 6 and the outer shell 4 form a receiving cavity that can place the knob assembly, and the PCB board 5 is fixed on the fixed rear shell 6 through the screws 8. It is fixed on the inner side wall of the casing 4 .

The household appliance provided in this embodiment includes the knob assembly described above. Since the knob assembly can achieve rapid assembly, the household appliance can also achieve the purpose of rapid assembly.
