Technical Field

The utility model relates to a dish washer technical field especially involves drawer type dish washer.

Background

As a novel dishwasher form, the drawer-type dishwasher has the characteristics of being embedded into a cabinet, compact in structure and free of squatting or stooping operation compared with a pull-down door type dishwasher, so that a user can obtain better use experience.

At present, drawer type dish washers usually have only one spray arm, and all are in the form of lower spray arms positioned at the bottom of a washing cavity, and the lower spray arms spray water upwards while rotating when working, so as to clean dishes. However, compared with the multi-layer spray arm mode of the pull-down door type dishwasher, the drawer type dishwasher has poor spraying effect, only because the direction of the water jet mainly upwards is single, and the bowl basket and the tableware have blocking effect, the lower spray arm is difficult to achieve sufficient spraying coverage, thereby causing the problems of insufficient washing or even unavailable washing in the washing cavity of the dishwasher, especially in the upper area.

If the arrangement of the top spray arm is added in the drawer type dish washing machine, the spraying effect is obviously improved, but the structural characteristics of the drawer type dish washing machine also provide great difficulties for designers, so that the addition of the top spray arm can be realized by a scheme which is innovative enough. Therefore, the current design of the spraying mode and the spraying system of the drawer dishwasher still needs to be broken through.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a drawer type dish washer which is different from the existing bottom spray washing so as to improve the dish washing effect of the dish washer.

A drawer type dish washing machine with a built-in water pipe comprises a shell, wherein a cover plate is arranged on the shell, a movable drawer is arranged on the shell, the cover plate can move up and down relative to the shell, a top spray arm with a water spray hole is arranged on the cover plate, a circulating water pump is arranged on the bottom surface of the drawer, and the circulating water pump is communicated with the top spray arm through a water inlet pipe. Drawer type dish washer still possesses the necessary structure of function of realizing washing dishes among this technical scheme, like filter equipment, drainage system etc. nevertheless this is not the improvement point of the utility model, and regarding these structures, technical personnel in the field can refer to prior art. Set up the top spray arm and supply water to the top spray arm through circulating water pump among this technical scheme, the top spray arm is from last down spraying water, combines the up spray rinsing of following of bottom spray arm, and the replenishment of mutually supporting can improve clean effect and cleaning efficiency. In addition, the inner container in the technical scheme is sealed by the cover plate, and particularly, when the dishwasher works, the cover plate is pressed on the inner container to seal the inner container. When the dishwasher stops working, the cover plate moves upwards to leave the inner container, and the inner container can be drawn out of the shell at the moment. When the dishwasher works again, the cover plate moves downwards until the cover plate is abutted against the inner container, and the inner container is sealed.

Further, the inlet pipe comprises a top spray inlet pipe and a top water pipe, and the top spray inlet pipe for supplying water to the top spray arm can move along with the movement of the drawer, namely, the top spray inlet pipe cannot influence the movement of the drawer. The top-spraying water inlet pipe is arranged inside the drawer, so that the structure of the dishwasher is compact, and the whole volume of the dishwasher is reduced. The top water pipe is arranged on the cover plate and can move along with the movement of the cover plate. When the cover plate is sealed with the inner container, the top water pipe is communicated with the water inlet pipe, the circulating water pump supplies water to the top spray arm, and the dish washing machine starts to clean. When the cover plate is separated from the inner container, the water jacking pipe is disconnected with the water inlet pipe, the water circulation pump stops supplying water, and the dish washing machine stops cleaning.

Further, the top water pipe extends from the center of the cover plate to the edge of the cover plate, the top spray water inlet pipe extends along the bottom surface and the side surface of the drawer, the top water pipe is communicated with the top spray water inlet pipe at the edge of the cover plate, and the top water pipe is communicated with the top spray arm at the center of the cover plate. The top spout inlet tube in this technical scheme can be the water pipe of plastics preparation, fixes the bottom surface at the drawer, moves along with the drawer motion. It will be appreciated by those skilled in the art that the top nozzle and the top spray arm have water inlet passages therein.

Furthermore, the water jacking pipe comprises a spray arm mounting seat, and the top spray arm is connected with the spray arm mounting seat through the clamping seat.

When the water inlet of the top water pipe is inserted into the water outlet of the top spraying water inlet pipe, the sealing ring is extruded to realize sealing.

Furthermore, a check valve is arranged in a water inlet of the top water pipe, and a top opening device matched with the check valve is arranged in a water outlet of the top spraying water inlet pipe. The check valve is a sphere, and the jacking device is a jacking column. When the drawer is pushed, the cover plate covers the opening above the drawer, meanwhile, the water inlet of the top water pipe is inserted into the water outlet of the top spraying water inlet pipe, the top column jacks up the ball to form a gap, and at the moment, the top spraying water inlet pipe is initially communicated with the top water pipe. And then the dishwasher starts to work, and water conveyed by the circulating water pump can further flush the ball body after passing through the top water pipe, so that the top water pipe and the top spraying water inlet pipe are communicated to the maximum extent. When the drawer is about to be pulled out, the cover plate is separated from the drawer, meanwhile, the water inlet of the top water pipe is disconnected with the water outlet of the top spraying water inlet pipe, and at the moment, the ball body can sink and block the water inlet of the top water pipe under the combined action of the self gravity and the residual water of the top water pipe, so that the non-return effect is formed.

On the basis, the utility model also provides a drawer dish washer that specifically has upper and lower spray arm the drawer bottom surface still is equipped with the lower spray arm that has the hole for water spraying, water diversion structure is connected to circulating water pump's delivery port, the top spout inlet tube with spray arm down the inlet tube respectively with water diversion structure intercommunication. The lower spray arm and the top spray arm respectively form water columns sprayed upwards from the bottom and sprayed and washed downwards from the top, and the two spray arms are opposite in rotation direction, so that the water spraying direction is more diversified, the problem of blocking of tableware is better solved, the washing coverage is more comprehensive, and the condition that the washing in the washing cavity of the drawer type dish washing machine, particularly the washing in the upper area is insufficient is effectively improved. Furthermore, the top water outlet of the top water pipe is higher than the water inlet of the top water pipe. When the dishwasher stops spraying, namely when water supply is stopped, the water outlet of the top water pipe is higher than the water inlet of the top water pipe, water accumulated in the inner cavity of the top water pipe gradually flows back to the water inlet under the action of self weight and then flows away from the water inlet, so that water accumulated in the top water pipe can be prevented from dripping into the drawer or out of the drawer.

Furthermore, the top water pipe is fixed on the cover plate through a support, and the top water pipe is connected with the support in a clamping manner. The header pipe may of course be connected to the cover plate by prior art connection means, such as by welding or gluing to the cover plate.
