Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a sink-type washing machine for washing tableware, fruits and vegetables. Background Art

[0002] The sink-type cleaning machine uses a sink to define a washing chamber and adopts an upward-flipping door structure.

[0003] For example, the applicant's prior patent ZL 202321042974.7 "A water tank cleaning machine" discloses a structure, which includes a water tank with a receiving cavity and a top opening connected to the receiving cavity; a spray arm, which is arranged in the receiving cavity of the water tank and connected to the first water supply channel; and a door body is arranged on the top of the water tank. The above structure is a common structure of a water tank cleaning machine.

[0004] A sink-type washing machine is generally small in size, and usually a layer of bowl baskets is placed near the bottom in the washing chamber. If upper and lower bowl baskets are set in the washing chamber, it is difficult to clean the upper bowl basket due to the obstruction of the lower bowl basket; if an upper spray arm structure of an existing built-in dishwasher is set between the upper bowl basket and the lower bowl basket, due to space limitations, the upper spray arm is prone to get stuck during rotation, affecting the spray range and cleaning effect. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a water tank type cleaning machine which can increase the spray range and stabilize the spray effect so as to improve the cleaning effect in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] A sink type cleaning machine comprises a sink body, a bowl basket, a lower spray arm and an upper spray arm, wherein the bowl basket is arranged in the sink body and close to the bottom of the sink body, the lower spray arm is arranged below the bowl basket, the upper spray arm is arranged above the bowl basket, an upper cover for forming a tableware placing area is arranged on the top of the bowl basket, the upper spray arm is accommodated in a semi-enclosed cavity constrained by the bottom of the upper cover, and a rotatable auxiliary nozzle is arranged on the upper spray arm.

[0008] The utility model provides an upper cover on the top of the bowl basket for placing tableware, thereby improving the utilization rate of the washing cavity and meeting the needs of washing more dishes; the upper spray arm is arranged in the semi-enclosed cavity formed at the bottom of the upper cover, which can not only make full use of the space but also protect the upper spray arm; the upper spray arm itself does not rotate and will not interfere with the bowl basket and tableware; the auxiliary nozzle on the upper spray arm that only rotates in a small area can meet the need for a larger spray range, so that the overall spray effect of the upper spray arm is stable, which is conducive to improving the cleaning effect.

[0009] Preferably, the bowl basket includes a bottom frame and a side frame extending upward from the edge of the bottom frame, and the upper cover is supported on the top of the side frame. The above structure is convenient for installing the upper cover, and an upper tableware placement area is formed above the upper cover.

With the above structure, on the one hand, the sunken area can provide space for installing the auxiliary nozzle, so that the auxiliary nozzle has more ample rotation space, ensuring that it rotates smoothly without interfering with the upper cover; on the other hand, the thinned water collection area can increase the water pressure, so that the auxiliary nozzle obtains greater rotation power, increases the impact force of the water column sprayed by the auxiliary nozzle, and thus improves the cleaning effect of the edge of the upper cover.

[0013] Preferably, the auxiliary nozzle is disc-shaped, the bottom wall of the auxiliary nozzle is provided with a water inlet sleeve rotatably connected to the water outlet, and the top wall of the auxiliary nozzle is provided with a spray hole that can change the spray direction as the auxiliary nozzle rotates. This structure is conducive to eliminating cleaning dead corners and improving cleaning effects.

A water pump assembly 6 is provided in the water return area 11.

[0026] The bowl basket 2 is arranged in the water tank body 1 and is arranged near the bottom of the water tank body 1. The lower spray arm 3 is arranged below the bowl basket 2 and above the filter plate 12. The lower spray arm 3 is connected to the first water outlet of the water pump assembly 6. The upper spray arm 4 is arranged above the bowl basket 2. The second water outlet of the water pump assembly 6 is connected to an inner water pipe 7 extending from bottom to top close to the inner wall of the water tank body 1. The upper spray arm 4 is connected to the inner water pipe 7 through a water guide pipe 8.

[0027] In this embodiment, an upper cover 5 for forming a tableware placement area is provided on the top of the bowl basket 2, and the upper spray arm 4 is accommodated in a semi-enclosed cavity 50 constrained by the bottom of the upper cover 5. A rotatable auxiliary nozzle 9 is provided on the upper spray arm 4. In this embodiment, an upper cover 5 for placing tableware is provided on the top of the bowl basket 2, thereby improving the utilization rate of the washing cavity and meeting more tableware washing needs; the upper spray arm 4 is provided by using the semi-enclosed cavity 50 formed at the bottom of the upper cover 5, which can not only make full use of the space, but also protect the upper spray arm 4. The upper spray arm 4 itself does not rotate and will not interfere with the bowl basket 2 and the tableware. The auxiliary nozzle 9 on the upper spray arm 4 that only rotates in a small area can meet the needs of a larger spray range, so that the overall spray effect of the upper spray arm 4 is stable, which is conducive to improving the cleaning effect.

[0028] Specifically, the bowl basket 2 includes a bottom frame 21 and a side frame 22 extending upward from the edge of the bottom frame 21, and the upper cover 5 is supported on the top of the side frame 22. The above structure is adopted to facilitate the installation of the upper cover 5, and an upper tableware placement area is formed above the upper cover 5. The upper cover 5 includes a top frame 51 and a side support frame 52 extending downward from the edge of the top frame 51, and the bottom of the side support frame 52 is mounted on the top of the bowl basket side frame 22, and the top frame 51 and the side support frame 52 together enclose a semi-enclosed cavity 50.
