Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-3, the present embodiment provides a preferred dishwasher spray device by taking a liner 1 with a square structure as an example, a spray seat 2 is fixed at the bottom center of the liner 1 of the spray device, an eccentric shaft 3 is rotatably sleeved on the spray seat 2, and a sprayer 4 is movably connected to the upper end of the eccentric shaft 3; the center of the sprayer 4 is provided with a first limiting groove 41 with a shape similar to that of the sprayer, the periphery of the spraying seat 2 is provided with a second limiting groove 5 similar to a square, the eccentric shaft 3 rotates under the common limitation of the first limiting groove 41 and the second limiting groove 5, so that the running track of the sprayer 4 is close to a rectangle, and the area of the running track is larger than that of an inscribed circle of the liner 1.
The eccentric shaft 3 of the invention rotates under the common limitation of the first limiting groove 41 and the second limiting groove 5, when one spray arm 42 of the sprayer 4 is consistent with the diagonal line of the inner container 1 (as shown in figure 2), the eccentric distance is positively contributed, the spray arm 42 fully extends to the corner of the inner container 1, which is beneficial to the cleaning of tableware at the corner; when a spray arm 42 of the sprayer 4 is aligned with the center line of the liner 1 (see fig. 3), the eccentric distance negatively contributes, and the sprayer 4 moves backward so that the spray arm 42 smoothly passes through the position. By moving in this way, the circular track of the existing sprayer is converted into a similar rectangular motion track (as shown by dotted lines in fig. 2 and fig. 3), so that the spraying water column is easier to spray to the corner of the inner container 1, and the occurrence of washing dead angles is effectively prevented.
Further, the eccentric shaft 3 of the present invention comprises a main shaft and a side shaft disposed above the main shaft, wherein the main shaft is used for movably connecting with the spray seat 2, and the side shaft is used for movably connecting with the sprayer 4. Specifically, the main shaft is movably sleeved on the spraying seat 2 in the radial direction and can rotate along the track of the second limiting groove 5; the side shaft penetrates into the first limiting groove 41 in the axial direction and is driven by the first limiting groove 41 to rotate. The invention limits the running track of the sprayer 4 to be square by the matching of the eccentric shaft 3 and the first limiting groove 41 and the second limiting groove 5, thereby greatly improving the spraying effect of the dish-washing machine.
Preferably, the shower 4 of the present embodiment includes three shower arms 42 arranged uniformly in the circumferential direction; accordingly, the first restriction groove 41 has a triangular shape, and the directions of the three corners of the first restriction groove coincide with the directions of the three shower arms 42. Specifically, the first limiting groove 41 is formed by sequentially connecting three concave circular arcs, and a chamfer is arranged at the joint of two adjacent circular arcs to ensure the motion stability of the eccentric shaft 3. Similarly, the second limiting groove 5 is formed by sequentially connecting four concave circular arcs, a chamfer is arranged at the joint of two adjacent circular arcs, and four corners of the second limiting groove 5 correspond to four corners of the inner container 1 respectively. Here, it should be noted that the shower 4 may be provided with not only three shower arms 42 but also four or more shower arms 42 as needed as long as the shape of the first regulating groove 41 is ensured to be similar to that of the shower 4.
Furthermore, the length of each spray arm 42 of the invention is larger than the half length of the central line of the liner 1, because the running track of the existing dishwasher sprayer is generally the inscribed circle of the liner 1, and the design can ensure that the track of the sprayer 4 is larger than the track of the inscribed circle of the liner 1, thereby effectively expanding the spray range of the sprayer. In addition, the length of each spray arm 42 should be less than half of the diagonal of the liner 1 to ensure that the spray arms 42 rotate smoothly in the liner 1.
Preferably, a plurality of water spray holes with upward openings are uniformly and densely distributed above the spray arm 42 of the present embodiment, and are used for spraying water columns upward to clean dishes. The invention enlarges the spraying range because the area of the running track of the sprayer 4 is larger than the area of the inscribed circle of the liner 1, can ensure that the water column is directly sprayed to a high place without being sprayed to the side wall of the liner 1 in an inclined way, greatly reduces the noise of the dish-washing machine, and improves the working efficiency of equipment and the utilization rate of water resources. In addition, the side of the spray arm 42 according to the invention is also provided with lateral water spray holes, which are not intended for cleaning, but for rotating the spray thrower 4 by means of a lateral spray water jet. The water column is used for driving, so that the structure of the dish washing machine is simplified, the volume of the dish washing machine is reduced, and the electric energy consumption is saved. Of course, the sprayer 4 can also be connected with the motor and driven by the motor to rotate along the side shaft.
Further, the eccentric shaft 3 and the spray seat 2 are both hollow, so that a water supply pipe can conveniently penetrate through the hollow; here, one end of the water supply pipe is communicated with the inner cavity of the shower 4, and the other end is communicated with the water distribution device. When the dish washer works, the water distribution device presses clean water into the water supply pipe, and the clean water is conveyed to the inner cavity of the sprayer 4 through the water supply pipe and finally is sprayed out from the water spraying holes on the sprayer 4 to wash the tableware.
Meanwhile, the embodiment also provides the dish washing machine comprising the spraying device of the dish washing machine, the dish washing machine is large in cleaning range and low in noise, and the problems that washing dead corners are easily generated in the washing process of the existing dish washing machine, the washing effect is poor, the cleaning is not thorough and the like are effectively solved.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
