Description

Technical Field

[0001] The utility model relates to the technical field of tableware washing equipment, in particular to a dishwasher. Background Art

[0002] Dishwashers clean dishes by flushing with water. Although special dishwashing powder or cleaning liquid is usually added to the water flow to improve the cleaning ability to remove stubborn stains on the dishes, due to the positional relationship between the bowl basket and the spray device, there are often cleaning dead corners in some positions of the bowl basket, resulting in the inability to thoroughly clean the dishes placed in it, affecting the cleaning performance.

[0003] There are improved technical solutions in the prior art. One of the bowl basket or the spray arm can be set to be movable, so as to achieve the largest possible coverage of the washing area. For example, the invention patent application with the publication number CN111728552A, entitled "Dishwasher with rotating spray arm", discloses a dishwasher with rotating spray arm; in addition, the invention patent application with the publication number CN109528128A, entitled "A rotating bowl basket integrated dishwasher", discloses a dishwasher with rotating bowl basket. By setting one of them to rotate, the cleaning problem can be solved to a certain extent, but it is still not thorough. In these technical solutions, whether the bowl basket rotates or the spray arm rotates, due to the setting of the spray arm and the shape of the bowl basket, the cleaning liquid sprayed during the movement generally cannot effectively cover the bowl basket area, so there are still some cleaning dead corners at individual positions. In addition, due to the limited number of spray arms, the relative position of the bowl basket rotates one circle, and the tableware at the fixed position is only rinsed for a short time. In order to ensure the effective cleaning time and cleaning effect, it can only be compensated by extending the working time of the dishwasher, which often leads to a relatively long single working time of the dishwasher. Utility Model Content

[0004] Aiming at the problem that the existing dishwashers are difficult to clean tableware effectively and completely, the utility model provides a dishwasher.

[0005] The technical solution of the utility model provides a dishwasher, comprising a washing chamber for washing tableware, wherein a central axis is arranged in the washing chamber, and a plurality of bowl baskets are arranged at intervals on the central axis, and the plurality of bowl baskets are all arranged to rotate around the central axis;

[0006] The bottoms of the multiple bowl baskets are all provided with spray holes, which are connected to the central axis water pipe in the central axis through the channel inside the bowl basket; the cleaning liquid flows into the internal channel of the bowl basket through the central axis water pipe and then sprayed out from the spray holes to clean the dishes.

[0007] Preferably, each of the bowl baskets is provided with a plurality of spray hole groups radiating outward from the center, and each spray hole group includes a plurality of the spray holes.

[0008] Preferably, the rotation directions of each two adjacent layers of bowl baskets on the central axis are opposite.

[0009] Preferably, the bowl basket is freely rotatable on the central axis, and the spray holes at the bottom of the bowl basket are deflected at a certain angle along the circumference of the bowl basket.

[0010] Preferably, the circumferential deflection angles of the spray holes of adjacent bowl baskets are opposite.

[0011] Preferably, the spray hole is a circular hole, a strip hole or a special-shaped hole.

[0012] Preferably, an upper spray hole is provided on the top of the cleaning chamber, and the cleaning liquid sprayed from the upper spray hole is used to clean the tableware in the bowl basket at the uppermost layer.

[0013] Preferably, the outer diameters of the plurality of bowl baskets gradually shrink from bottom to top in a pagoda shape as a whole.

[0014] Preferably, the cleaning chamber has a substantially revolution-shaped housing.

[0015] Preferably, the housing is provided with a side door for substantially exposing all of the bowl basket.

[0016] The dishwasher of the utility model realizes layered washing of tableware by using a bowl basket arranged in multiple layers in a washing chamber. At the same time, a spray hole is provided at the bottom of the bowl basket for spraying washing liquid. Since the bowl basket is provided with the spray hole and can rotate, when washing tableware, not only the position of the tableware changes with the rotation of the bowl basket, but also the position of the spray hole on the upper layer thereof changes. The two are staggered, so that the tableware can be impacted at different angles during the movement, thereby avoiding the occurrence of a dead corner for washing and ensuring the washing effect of the tableware.

[0022] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. In this specification, the size ratios in the drawings do not represent the actual size ratios, but are only used to reflect the relative position relationship and connection relationship between the components. Components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0023] Figure 1 Schematic diagram of the structure of the dishwasher of the present invention, which includes a washing chamber C for washing dishes, a central axis 1 is set in the washing chamber C, and a plurality of bowl baskets 2 are arranged at intervals on the central axis 1, and the plurality of bowl baskets 2 are all rotatably arranged around the central axis 1. Figure 2 and Figure 3 All of them are schematic diagrams of the bowl basket 2 in different directions. Several of the bowl baskets 2 are provided with spray holes 21 at the bottom, and the spray holes 21 are connected to the central axis water pipe in the central axis 1 through the channel inside the bowl basket 2. The cleaning liquid flows into the internal channel of the bowl basket 2 through the central axis water pipe and then sprays out from the spray holes 21, thereby spraying onto the tableware on the lower bowl basket 2 to clean the tableware on the lower bowl basket 2. During the spray flushing process, the bowl basket 2 can rotate on the central axis 1, so that the tableware can be rinsed at different angles during the rotation of the bowl basket 2 to ensure that the tableware can be fully cleaned. Preferably, the spray holes 21 are distributed circumferentially at the bottom of the bowl basket 2 to ensure that the lower bowl basket is continuously rinsed during the rotation of the bowl basket 2, so that during the rotation flushing process, the tableware on the lower bowl basket 2 is always in an uninterrupted flushing operation, thereby improving the cleaning efficiency. In order to ensure the continuity of the internal channel from the central axis water pipe to the basket 2 during the relative rotation of the basket 2 and the central axis 1, an optional solution is to open a hole on the central axis 1 at the junction of the two, and to provide a corresponding annular groove matching the hole on the basket 2. Since the spray hole 21 is arranged at the bottom of the basket 2, it is equivalent to only needing one set of motion mechanism to realize the rotation of the basket and the spray device, thereby simplifying the equipment structure on the basis of realizing the basket and the spray device.

[0024] The multiple baskets 2 can be driven by a driving device to rotate on the central axis 1 in a controlled manner, and preferably the rotation directions of each two adjacent layers of baskets are opposite. That is, if the first layer of baskets 2 rotates clockwise, the second layer of baskets 2 rotates in the opposite direction (counterclockwise), and then the third layer of baskets 2 continues to rotate in the opposite direction (clockwise) relative to the second layer, and so on. In this way, the rotation directions of each two adjacent layers of baskets are opposite, considering that the bottom spray holes 21 of the upper layer of baskets 2 spray downward to act on the tableware on the lower layer of baskets 2 to clean. Reverse rotation is conducive to staggering the movement between the two layers, ensuring that the sprayed water column acts on the tableware at different angles and speeds, so that the tableware can be cleaned.

[0025] A more preferred technical solution for the bowl basket 2 is to use hydraulic drive to rotate without using a power drive device. Specifically, the bowl basket 2 can be freely rotated on the central axis 1, and the holes at the bottom of the spray holes 21 are specifically set to deflect at a certain angle along the circumference of the bowl basket 2. When water is passed, the water for cleaning is sprayed out from the spray holes 21, and at the same time reacts to the bowl basket 2, and the bowl basket 2 rotates in the opposite direction of the spraying direction. On this basis, the circumferential deflection angles of the spray holes 21 on adjacent bowl baskets 2 should be opposite, so that the adjacent bowl baskets 2 rotate in opposite directions under the power of the sprayed water, thereby, as mentioned above, helping to improve the cleaning effect. At this time, the water flow impacting the tableware will also promote the rotation of each layer of the bowl basket 2. The spray holes 21 are distributed circumferentially on the bowl basket 2 to cover the circumferential area at the bottom of the bowl basket 2. In practice, the bowl basket 2 will be provided with a drain hole to ensure that the sewage from washing the dishes thereon can flow out from the drain hole. Therefore, in order to avoid the drain hole, a plurality of spray hole groups are radially arranged from the center to the outside on the bowl basket 2, and each spray hole group includes a plurality of spray holes 21 distributed radially. Therefore, during the entire washing process, the rotation of the bowl basket 2 can be achieved without relying on external force. Based on the above technical solution, if Figure 1 As shown, for the bottommost basket 2 placed on the central axis 1, although it is preferred to open the basket 2 at the bottom to drive its rotation, since there is actually no basket 2 below it, the spray hole 21 opened at the bottom is not necessary. In addition, for the topmost basket 2, in order to achieve the cleaning of the tableware on it, an upper spray hole C1 can be opened at the top of the washing chamber C, that is, above the topmost basket 2. The cleaning water sprayed by the upper spray hole C1 acts on the topmost basket 2 to achieve the cleaning of the tableware on it. The distribution area of ​​the upper spray hole C1 generally covers the area of ​​the topmost basket 2 so that the tableware on the basket 2 can be evenly and continuously rinsed during the rotation of the basket 2. There is no special requirement for the specific cross-sectional shape of the spray hole 21. It can be a circular hole or a strip hole. When the spray hole 21 is a strip hole, it is generally opened along the circumference or radial direction of the basket 2, avoiding the drain hole opened on the basket 2.

[0026] like Figure 2 and Figure 3As shown, the outer diameters of different baskets 2 are preferably contracted from bottom to top so that the baskets 2 gradually contract in a pagoda shape as a whole. On the one hand, the load capacity of each layer of baskets 2 is gradually reduced, which is conducive to optimizing the force of the local structure composed of the baskets 2 and the central axis 1, and ensuring the stability of the structure. On the other hand, more importantly, a certain difference is made between the outer diameters of each adjacent layer of baskets 2, leaving a certain space where the outer circumference of the lower layer basket is larger than that of the upper layer basket, so that it is convenient for users to take out tableware W from the lower layer basket 2. The washing chamber preferably has a substantially revolving shell C2, which satisfies the rotation space of the baskets 2 while making the dishwasher have a lower space occupancy. On this basis, the spray holes 21 arranged on each layer of baskets 2 have a circumferential deflection angle and can also be optionally deflected radially outward to ensure that the cleaning liquid sprayed from the spray holes 21 can act on the protruding edge portion of the lower layer basket to ensure the coverage of the lower layer basket. The shell C2 preferably has a side door C3 that substantially exposes all the baskets 2. After cleaning is completed, the side door C3 is opened, and all the bowl baskets 2 are partially exposed at the opening. The user can flexibly take out the tableware at any position on the bowl basket 2 by rotating any bowl basket 2.

[0027] The above content is only a description of the preferred implementation mode of the utility model, and does not limit the scope of the utility model. Without departing from the design spirit of the utility model, various modifications and improvements made to the technical solution of the utility model by ordinary technicians in this field should fall within the protection scope determined by the claims of the utility model.
