DETAILED DESCRIPTION

[0035] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] like Figure 1 and Figure 2 As shown, the projection adjustment mechanism provided by the utility model can be applied to, but not limited to, a dishwasher 1, and can also be applied to other kitchen appliances, such as a disinfection cabinet, a steam oven, etc., to project the status information of the appliance to the ground in real time for users to view.

[0037] like Figure 3 As shown, the projection adjustment mechanism includes: a fixing part 4, a projection mechanism and a reflector 6. The fixing part 4 is a fixed structure, such as a support frame or a housing of an electrical appliance. The projection mechanism is connected to the main controller of the electrical appliance to generate a projection pattern. The reflector 6 is used to reflect the projection pattern to a projection surface. In this embodiment, the projection surface is the ground. In other feasible solutions, the projection surface can also be a panel provided by the electrical appliance.

[0038] The reflector 6 and the projection mechanism are both connected to the fixing portion 4 .

[0039] like Figure 4 , Figure 5 and Fig. 9As shown, the reflector 6 can be fixedly connected to the fixing part 4, or can be movably connected to the fixing part 4. In this embodiment, the reflector 6 is connected by a fixed connection. A mounting recess 43 is provided on the top surface of the fixing part 4, and the area and shape of the mounting recess 43 are substantially the same as those of the reflector 6. The mounting recess 43 is used to accommodate the reflector 6. A guide foot 44 is provided around the mounting recess 43. The guide foot 44 partially extends into the mounting recess 43. The guide foot 44 can be deformed under external force. During installation, the reflector 6 can pass over the guide foot 44 and enter the mounting recess 43. After the reflector 6 enters the mounting recess 43, the guide foot 44 returns to its original state, and can support the reflector 6 to prevent it from falling from the mounting recess 43. Of course, the reflector 6 can also be connected to the fixing part 4 by other conventional mechanical connection methods, for example, directly pasted on the fixing part 4 by adhesive.

[0040] like Figure 4 and Figure 6 As shown, the reflector 6 and the projection mechanism can be located at the front and rear sides of the fixing part 4. In this case, a evacuation hole 45 for evacuating the light emitted by the projection mechanism is provided on the fixing part 4. After the light emitted by the projection mechanism passes through the evacuation hole 45, it is irradiated on the reflector 6 and finally reflected and falls on the projection surface. The projection mechanism is movably connected to the fixing part 4, for example, it can be connected by rotating or sliding, so that the incident angle of the light can be adjusted.

[0041] Before the projection mechanism is used, the relative position between the projection mechanism and the fixing part 4 can be adjusted to change the incident angle of the projection mechanism, thereby changing the position of the projection pattern of the reflector 6 on the projection surface until the projection pattern is not blocked. Figure 3 As shown, after adjusting the angle a to angle b, the projection pattern will move forward. In this solution, by changing the incident angle of the projection mechanism, the position of the projection pattern is changed, which solves the problem of incomplete projection pattern caused by assembly or transportation in the prior art.

[0042] In this embodiment, the projection mechanism includes a connecting plate 7 and a projection module 51, and the projection module 51 is connected to the connecting plate 7. The connecting plate 7 includes a first end and a second end opposite to each other, and the first end is fixedly connected to the fixing portion 4, and a hinge is formed at the connection. The second end of the connecting plate 7 and the fixing portion 4 are connected via an adjustment structure, and the adjustment structure is used to change the distance between the second end and the fixing portion 4 so that the inclination angle of the connecting plate 7 changes. When the inclination angle of the connecting plate 7 changes, the emission angle of the projection mechanism thereon changes.

[0043] Specifically, Figure 7 and Figure 8As shown, the second end is provided with an adjusting screw hole 72 ; the adjusting structure comprises an adjusting screw 8 , the adjusting screw 8 is rotatably connected to the fixing portion 4 , and the adjusting screw 8 is threadedly connected to the adjusting screw hole 72 .

[0044] The first end of the connecting plate 7 remains in a constant position. When the user rotates the adjusting screw 8, the second end moves toward or away from the fixing portion 4, thereby changing the inclination angle of the connecting plate 7. After the adjustment stops, the second end maintains the current position without the need to set a separate locking structure.

[0045] The adjusting screw 8 only rotates relative to the fixing portion 4 without generating axial movement, which facilitates adjusting the position of the second end. Fig.10 As shown, a front limit protrusion 81 and a rear limit protrusion 82 protruding outward are provided on the peripheral wall of the rod portion of the adjusting screw 8, the front limit protrusion 81 is located on one side of the fixing portion 4, and the rear limit protrusion 82 is located on the other side of the fixing portion 4, and both the front limit protrusion 81 and the rear limit protrusion 82 cannot pass through the fixing portion 4, so as to prevent the adjusting screw 8 from moving relative to the fixing portion 4 along the axial direction of the adjusting screw 8.

[0046] like Figure 7 As shown, the adjusting screw hole 72 is arranged at the edge of the connecting piece to prevent the user's hand from blocking the projection pattern during adjustment. In this embodiment, the adjusting screw 8 is close to the left edge or the right edge of the connecting piece, rather than the middle position.

[0047] In order to facilitate the assembly of the adjusting screw 8, an assembly hole 41 and a limiting hole 42 are provided on the fixing portion 4. The assembly hole 41 is connected to the limiting hole 42, and the width of the connection point between the two is smaller than the diameter of the rod of the adjusting screw 8; the diameter of the assembly hole 41 is greater than or equal to the diameter of the front limiting protrusion 81; the diameter of the limiting hole 42 is smaller than the diameters of the front limiting protrusion 81 and the rear limiting protrusion 82.

[0048] like Fig. 9 As shown, the cross-sectional shape of the assembly hole 41 and the limiting hole 42 after being connected is roughly in the shape of an "8", and the connection between the two is relatively narrow to prevent the rod of the adjusting screw 8 from passing smoothly. During assembly, the adjusting screw 8 is first passed through the assembly hole 41, and after the front limiting protrusion 81 completely passes through the assembly hole 41, the adjusting screw 8 is pressed downward to make the rod pass through the connection between the assembly hole 41 and the limiting hole 42. Under the action of external force, the connection can be deformed to make the rod enter the limiting hole 42. The subsequent adjustment of the adjusting screw 8 is completed in the limiting hole 42, and the front limiting protrusion 81 and the rear limiting protrusion 82 cannot pass through the limiting hole 42. Therefore, the adjusting screw 8 can only rotate relative to the fixing portion 4, but cannot produce axial movement.

[0049] like Figure 8 As shown, in order to further increase the elasticity of the connecting plate 7 and make the adjustable tilt angle of the connecting plate 7 larger, the first end is connected to a flange 71 that flips toward the direction of the second end, there is a gap between the flange 71 and the first end, the flange 71 is fixedly connected to the fixing portion 4, and the first end and the flange 71 form a "U"-shaped structure to form an elastic support with a larger deformation space.

[0050] The flange 71 can be connected to the fixing portion 4 by two left and right screws 9 .

[0051] The projection module 51 and the connection plate 7 may be connected by threads or by snap-fitting.

[0052] like Figure 7 As shown, in this embodiment, a mounting hole is provided at a portion between the first end and the second end of the connecting plate 7, and a clamping hole 73 is provided on the inner wall of the mounting hole. The projection mechanism also includes a fixing ring 52, and the projection module 51 and the fixing ring 52 are connected by threads, and a buckle is provided on the circumferential side wall of the fixing ring 52, and the buckle is engaged with the clamping hole 73. The connecting plate 7, the fixing ring 52 and the projection module 51 are connected as a whole, and the projection module 51 and the fixing ring 52 are connected by threads, so as to facilitate the disassembly of the projection module 51.

[0053] The number of buckles should be ≥ 2, preferably 3 evenly distributed, so that the structural strength is better, the structure is stable and not easy to shake, and the anti-drop strength is better.

[0054] The material of the connecting piece can be metal or plastic.

[0055] The reflector 6 can be made of glass or metal.

[0056] The head of the adjusting screw 8 is provided with a flat-blade shape, which is convenient for adjustment using a flat-blade screwdriver, thereby improving the convenience of adjustment.

[0057] The dishwasher 1 provided by the present invention includes the above-mentioned projection adjustment mechanism. Since the dishwasher 1 provided by the embodiment of the present invention uses the above-mentioned projection adjustment mechanism, the dishwasher 1 provided by the embodiment of the present invention also has the advantages of the projection adjustment mechanism.

[0058] The dishwasher 1 is embedded in the cabinet 2, and a skirting board 3 is installed at the bottom of the cabinet 2. The entire projection adjustment mechanism is located at the bottom of the dishwasher 1.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
