Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.

The embodiment provides a dishwasher, which comprises a base 1 and an inner container (not shown in the figure) arranged on the base 1, wherein as shown in fig. 2, a bottom surface of one end, away from a dishwasher door, of the base 1 is provided with at least one first accommodating cavity 11, a footing is arranged in the first accommodating cavity 11 in a penetrating manner, the footing comprises an adjusting rod 2 and a gear nut 3, and the gear nut 3 is screwed on the adjusting rod 2 through threads. The adjusting rod is matched with the gear nut and can be used for adjusting the height of the dishwasher. When the base 1 is produced, the independent dish washer and the embedded dish washer can be produced simultaneously only by using the same die, and the adjusting feet of the two dish washer bases can be jointly applied to one accommodating cavity, so that the space in the base is saved. The base 1 comprises a front wall 12, a rear wall 13, a bottom wall 14 and two side walls 15, wherein each side wall 15 is respectively connected with the front wall 12 and the rear wall 13, and a second accommodating cavity 151 is arranged at the lower end of each side wall 15. Wherein the first accommodating chamber 11 and the second accommodating chamber 151 are arranged in communication through a communication hole, and the center lines of the two chambers are perpendicular.

The first accommodating cavities 11 are specifically arranged at two corners of the bottom surface of the base in this embodiment, but the first accommodating cavities 11 may be arranged in the middle of the bottom surface of the base in other embodiments. I.e. the middle of the underside of the end of the base 1 remote from the dishwasher door.

As shown in fig. 3, one end of the gear nut 3 is provided with at least two first limiting grooves 31, and the first limiting grooves 31 are circumferentially and uniformly distributed on the periphery of the gear nut 3; the adjusting rod 2 is a screw rod, and a second limiting groove 21 is arranged along the axial direction of the adjusting rod 2. By providing the gear nut 3 and the adjustment lever 2 in this manner, the gear nut 3 and the adjustment lever 2 can be rotationally moved, and the adjustment lever 2 can also be rotationally moved relative to the gear nut. The height adjustment of the base 1 can be achieved for different types of dishwashers.

As shown in fig. 4 and 5, when the base is applied to a stand-alone dishwasher, the top of the first accommodating cavity 11 is provided with a limiting protrusion 111, the two limiting protrusions 111 are symmetrically arranged, and the limiting protrusion 111 extends into the first limiting groove 31 and clamps the gear nut 3, i.e. the limiting protrusion 111 is used for limiting the rotation of the gear nut, and when the height needs to be adjusted, the height adjustment can be realized only by screwing the adjusting rod 2. This spacing arch 111 need add the lug of two symmetry settings in the position department that the first chamber 11 that holds is made to the mould in manufacturing process, and then can realize spacing arch 111 and the first chamber 11 integrated into one piece that holds.

As shown in fig. 7, when the base is applied to the built-in dishwasher, the dishwasher further includes a driving rod 4, one end of the driving rod 4 passes through the second receiving cavity 151 and extends into the first receiving cavity 11, and a driving gear 5 engaged with the gear nut 3 is disposed at one end of the driving rod 4 extending into the first receiving cavity 11. Wherein, drive gear 5 is bevel gear, adjusts pole 2 and rotates along with gear nut 3 together in order to prevent to rotate the in-process of drive gear 5, leads to the altitude mixture control to be obstructed, and the one end of keeping away from actuating lever 4 of drive gear 5 is provided with for this reason and prevents rotating protruding 51, prevents rotating protruding 51 and stretches into in the spacing recess 21 of second. Of course, the anti-rotation protrusion 51 may also be the end of the driving rod 4 protruding out of the driving gear 5, i.e. the driving rod 4 passes through the driving gear 5 and penetrates into the second limiting recess 21. However, the rotation preventing protrusions 51 are provided to restrict the rotation of the adjustment lever 2. The length of the driving rod 4 should be greater than the length of the side wall 15 of the base 1 or slightly less than the length of the side wall 15. Generally, in order to make the overall appearance of the dishwasher attractive, the length of the driving lever 4 is slightly smaller than that of the side wall 15, while the front wall 12 is provided with a third accommodating cavity 121 (refer to fig. 8), and the other end of the driving lever 4 (i.e. the end not provided with the driving gear 5) is positioned in the third accommodating cavity 121. The other end of the driving rod 4 is provided with an adjusting head 41, and the adjusting head 41 extends into the third accommodating cavity 121 and is hidden, so that the overall aesthetic property of the dishwasher is improved.

As shown in fig. 6 and 9, since the driving rod 4 has a large length and is bent in a long-term working process, in order to solve the problem, a plurality of support ribs 1511 arranged in parallel are further disposed in the second accommodating chamber 151, and each support rib 1511 is provided with a support groove 15111. The driving lever 4 is positioned in the supporting groove 15111, so that the driving lever 4 can be supported to prevent the driving lever 4 from being bent.

As shown in fig. 8, the bottom surface of the adjusting lever 2 may be higher than the bottom surface of the bottom wall 14 of the base 1 during the rotation of the adjusting lever 2, so that the adjusting lever 2 cannot function as a support, and for this reason, a partition 112 is further disposed in the first accommodating cavity 11 to prevent the adjusting lever 2 from being over-screwed.

The dish washer base that provides in this embodiment can use on independent type dish washer, also can use on embedded dish washer, and this kind of base need not set up the chamber that holds to different grade type dish washer, just can realize the altitude mixture control to different grade type dish washer, and then has saved the inner space of dish washer base greatly, makes things convenient for designer's increase to set up the spare part size in the base or increase spare part as required. Since the gear nut 3 is in threaded fit with the adjusting rod 2, the connecting mode can be suitable for different types of dishwashers.

It is noted that the foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
