Consequently, the detergent is wasted to a certainty degree, or the clothes can't be cleaned thoroughly because of an inadequate dose of detergent. To improve convenience and easiness of clothes washing, presently most washing machines have a detergent box assembly that can dose the detergent automatically, to solve the problem of inconvenient and inaccurate dosing of detergent.
For example, a drum-type washing machine comprises a cabinet, an outer tub and an inner tub arrange in the cabinet, and a detergent box arranged in the top part of the cabinet and configured to release detergent and softener, etc.; the detergent box comprises a fixed box body and a drawer that can be pushed in/pulled out, wherein, the box body is connected to the outer tub through a tube, so that the detergent in the detergent box can be released through the tube into the outer tub. An access hole to the drawer is arranged in a control panel on the top front of the cabinet; a drawer handle is provided on the front end of the drawer, so that the drawer can be pushed in/pulled out conveniently; the drawer handle is flush to the control panel after the drawer is closed. Based on the requirement for individualized appearance, most existing drawer handles are injection-molded separately, a decorative plate is attached to the main body of the handle by means of adhesive or a fastener structure and covers the outer side of the main body of the handle, and the decorative plate may be utilized to print a logo on it. For example, a snap-fit fixing structure is disclosed in Chinese Patent Document No. 201510936558.5 , wherein, at least two fastening hooks are provided on the decorative plate, through-holes through which the fastening hooks can pass are arranged in the main body of the handle, and fastening holes that can be fitted with the fastening hooks are provided in the handle. The fastening hook comprises two fixed pillars spaced from each other on the decorative plate, a cross column connecting the two fixed pillars, and a fastening stub extending forward on the cross column, with a protruding hook arranged on the front end of the fastening stub.

Detailed Description of the Embodiments

Hereunder some embodiments of the present invention will be detailed with reference to the accompanying drawings. It should be understood that the embodiments described here are only provided to describe and explain the present invention, but shall not be deemed as constituting any limitation to the present invention.
As shown in Figs. 1 and 2, the decorative plate 17 provided in the present invention comprises a plate body 1 provided with fasteners on its back surface opposite to its decorative surface, wherein, the fasteners comprise double-side fasteners 2, each of which includes a fastening stub 3 that projects outwardly from the back surface and has opposite protruding hooks 4 that are formed on opposite sides of the fastening stub 3 and protrude outwardly from the respective sides.
In the technical scheme described above, since the fastening stubs 3 directly project from the decorative plate and each fastening stub 3 has opposite protruding hooks 4 that are formed on two opposite sides of the fastening stub 3 and protrude outwardly from respective sides, any other supporting member is avoided between the protruding hooks 4 and the decorative plate, except the fastening stubs 3; besides, the fastening stubs 3 directly project outwardly from the decorative plate, e.g., integrally, and thereby the strength of the fastening stubs 3 is improved significantly. In that way, when the decorative plate is assembled, the fastening stubs 3 are inserted into a mounting base, e.g., into corresponding double-side fastening holes in a handle element described below, so that the protruding hooks 4 push aside two opposite fastening edges in each of the double-side fastening holes and are snap-fitted in the double-side fastening holes; in such a way, the double-side fasteners have smaller deformation, and are not easy to break, subject to smaller insertion resistance, and easy to assemble. Herein, it should be understood: in the decorative plate in the present invention, the protruding hooks 4 on the two opposite sides of the fastening stub 3 may be in different structural forms. For example, in a structural form, the protruding hooks 4 may be semi-circular or hemi-spherical; or, in a preferred structural form, as shown in Fig. 2, a front side surface 5 of the protruding hook 4 (i.e., the top part of the drawing in Fig. 2) forms a slope surface, so that two opposite front side surfaces 5 form a splayed shape, and thereby the slope front side surfaces 5 can push aside fastening edges 14 more easily when the double-side fastener is fitted with a double-side fastening hole described below.
Furthermore, as shown in Fig. 2, a rear side surface 6 of the protruding hook 4 (i.e., the bottom part of the drawing in Fig. 2) form a slope surface, so that two opposite rear side surfaces 6 form an inverted splayed shape, and thereby the slope rear side surfaces 6 contact with the fastening edges 14 in a larger area so as to improve the stability of the snap-fitting when the double-side fastener and the double-side fastening hole are fitted with each other; besides, the double-side fastener can be disengaged from the double-side fastening hole easily when the decorative plate is to be removed from the mounting base, owing to a guiding effect of the slope rear side surfaces 6.
In addition, the opposite protruding hooks 4 may be formed on the middle part or upper part of the fastening stub 3; alternatively, as shown in Fig. 2, preferably the protruding hooks 4 are formed on the front end part of the fastening stub 3 to take full advantage of the length of the fastening stub 3 and avoid excessive overall length of the double-side fastener.
Furthermore, for the convenience of snap-fitting and releasing, preferably, as shown in Fig. 2, the front side surface 5 and the rear side surface 6 of each protruding hook 4 are connected via a convex arc surface; in that way, the most producing point of the protruding hook 4 can pass by the fastening edge more easily in the snap-fitting or releasing process.
In addition, to facilitate the protruding hook 4 to wedge into the space between the two fastening edges, preferably, as shown in Fig. 2, the front end face of the fastening stub 3 forms a convex arc surface to connect the two opposite front side surfaces 5 on the two side in an arc form. Thus, the arc surface enters into the space between the two fastening edges first, and guides the slope front side surfaces 5 to push aside the two fastening edges.
Furthermore, as shown in Figs. 1 and 2, to improve the structural strength of the fastening stub 3 and improve the stability of fitting between the double-side fastener and the double-side fastening hole, preferably, a triangular reinforcing plate 8 comprising straight-edge surfaces and a slope surface 7 is connected between each of the two opposite sides of the fastening stub 3 and the back surface, wherein, the two straight-edge surfaces of the triangular reinforcing plate 8 is connected with the side and the back surface respectively. Since the slope surfaces 7 are exposed, as shown in Fig. 9, when the double-side fastener is inserted and fitted in the double-side fastening hole, the two triangular reinforcing plates 8 will be accommodated in the space between the two fastening edges 14, so that the space attains a spatial positioning effect for the two triangular reinforcing plates; more preferably, the slope surfaces 7 will abut against the slope surfaces of the fastening edges 14 arranged in a slope manner, so as to further improve positioning reliability.
Furthermore, the quantity of the double-side fasteners 2 may be selected according to the actual requirement. For example, as shown in Fig. 1, a plurality of double-side fasteners 2 are provided and arranged at an interval along the edge on one side of the back surface in the length direction of the decorative plate. Thus, the edge on the side of the decorative plate is stably and reliably fitted via the plurality of double-side fasteners 2 arranged at an interval.
Furthermore, as shown in Fig. 1, to improve assembling reliability of the decorative plate, preferably, the fasteners comprise a plurality of first single-side fasteners 9, which are arranged at an interval along the edge on the other side of the back surface in the length direction of the decorative plate. Of course, single-side fastening holes 15 that can be fitted with the first single-side fasteners 9 are formed in the mounting base, e.g., the handle element described below. In addition, the first single-side fasteners 9 may comprise stubs and fastening hooks projecting from the stubs.
Furthermore, at least one first single-side fastener 9 in the middle area of the edge on the other side of the decorative plate comprises a connecting stub that projects from the plate body and a positioning and fastening edge that projects outwardly from a front end of the connecting stub towards the edge on the other side, wherein the positioning and fastening edge extends obliquely towards the back surface of the plate body to form an included angle smaller than 90° (preferably slightly smaller than 90°, e.g., 85-88°) between the positioning and fastening edge and the connecting stub, and is configured to be fastened and positioned in a positioning space on the periphery of a positioning hole in the mounting base. Thus, when the decorative plate is assembled, the positioning and fastening edges can be inserted downwards into the mounting base, e.g., into single-side fastening holes 15 in the handle element described below, so that the periphery of each of the single-side fastening holes 15 is positioned in a positioning space to attain a pre-positioning effect, to facilitate the operator to insert the decorative plate to the correct position easily.
Furthermore, as shown in Fig. 1, the fasteners comprise positioning stubs 11 and second single-side fasteners 10, wherein, the positioning stubs 11 are formed on the edges at the two ends of the back surface in the length direction of the decorative plate, so as to achieve more stable and reliable positioning during the assembling.
In addition, at least two second single-side fasteners 10 are arranged at an interval in the length direction of the decorative plate between the positioning stubs 11 at the two ends; thus, the reliability of connection on the edges at the two ends of the decorative plate is improved by means of the fitting between the second single-side fasteners 10 and the corresponding single-side fastening holes.
In addition, at least two double-side fasteners 2 are arranged at an interval in the length direction of the decorative plate between the positioning stubs 11 at the two ends; thus, as described above, the reliability of connection in the middle area of the decorative plate is improved by means of said at least two double-side fasteners 2.
Of course, in the decorative plate in the present invention, the positional relation among the fasteners is not limited to the positional relation described above, and may be adjusted according to the actual requirement. For example, as shown in Fig. 1, at least two double-side fasteners 2 are arranged between the second single-side fasteners 10 between the positioning stubs 11 at the two ends.
In addition, the orientation of the fastening hooks of the first single-side fasteners 9 are reversed to the orientation of the fastening hooks of the second single-side fasteners 10, to realize snap-fitting in which the members abut against each other in different directions.
In addition, the present invention provides a handle element 18. As shown in Figs. 3, 4 and 5, the handle element 18 comprises a plate body, which has fastening holes that are formed on an external surface (i.e., front surface) of the plate body for mounting a decorative plate and configured to snap-fit with fasteners on the decorative plate, wherein, the fastening holes comprise double-side fastening holes 12 configured to fit with double-side fasteners on the decorative plate, and wherein the double-side fastening hole 12 comprises an insertion opening 13, which has fastening edges 14 that are formed on two opposite sides of the insertion opening 13, extend towards the interior of the plate body, and configured to fit with the protruding hooks 4 of corresponding double-side fastener. Thus, as described above, when any decorative plate 17 described above is fitted with the handle element 18, the fastening stubs 3 are inserted into corresponding double-side fastening holes 12 in the handle element 18, so that the protruding hooks 4 push aside the two opposite fastening edges 14 in each of the double-side fastening holes 12 and are snap-fitted in the double-side fastening holes 12; in that way, the double-side fasteners and the fastening edges 14 have smaller deformation and are not easy to break; besides, the double-side fasteners are subject to smaller insertion resistance and easy to assemble.
Of course, in the handle element in the present invention, the two fastening edges 14 in the double-side fastening hole may be in different structural forms. For example, they may be elastic plates extending straightly and levelly; alternatively, as shown in Fig. 5, two opposite fastening edges 14 extend obliquely to get closer to each other to form a splayed shape; as shown in Fig. 9, with such a structure, the double-side fastener can be snap-fitted more easily. Besides, as shown in Fig. 9, when the double-side fastener is inserted and fitted in the double-side fastening hole, the two triangular reinforcing plates 8 will be accommodated in the space between the two fastening edges 14, so that the space attain a spatial positioning effect for the two triangular reinforcing plates; more preferably, the slope surfaces 7 will abut against the slope surfaces of the fastening edges 14 arranged in a slope manner, so as to further improve positioning reliability.
In addition, the fastening holes further comprise single-side fastening holes 15 configured to snap-fit with single-side fasteners on the decorative plate and positioning holes 16 configured to fit with positioning stubs on the decorative plate. Of course, a single fastening edge is formed in the single-side fastening hole 15.
Furthermore, the present invention provides a handle. As shown in Figs. 6-9, the handle comprises any handle element 18 described above and any decorative plate 17 described above, wherein, the fasteners on the decorative plate 17 are fitted with the fastening holes in the handle element.
Specifically, the fastening stubs 3 of the double-side fasteners 2 on the decorative plate penetrate into the insertion openings 13 of the double-side fastening holes 12 in the handle element, so that the opposite protruding hooks 4 are snap-fitted with the opposite fastening edges 14.
In that way, the double-side fasteners and the fastening edges 14 have smaller deformation and are not easy to break; in addition, the double-side fasteners are subject to smaller insertion resistance and easy to assemble.
Furthermore, in a case that a triangular reinforcing plate 8 comprising straight-edge surfaces and an slope surface 7 is connected between the two opposite sides of the fastening stub 3 and the back surface and the two opposite fastening edges 14 extend obliquely to get closer to each other so that they form a splayed shape, as shown in Fig. 9, the two triangular reinforcing plates 8 are accommodated in a space between the two fastening edges 14. That is to say, when the double-side fastener is inserted and fitted in the double-side fastening hole, the two triangular reinforcing plates 8 will be accommodated in the space between the two fastening edges 14, so that the space attains a spatial positioning effect for the two triangular reinforcing plates; more preferably, the slope surfaces 7 will abut against the slope surfaces of the fastening edges 14 arranged in a slope manner, so as to further improve positioning reliability.
Furthermore, the present invention provides a washing product accommodation box, which comprises a box body and a drawer that are fitted with each other, wherein, a front end face of the drawer is provided with any handle described above. Thus, as described above, the service life and overall quality of the washing product accommodation box are significantly improved.
