Description

Technical Field

By setting a drain area covered with a drain plate and setting the water pump in the drain area, the water pump is isolated from the washing area, so that the water flowing back into the water pump is first filtered by the drain plate.

[0004] The sink of a sink-type washing machine is generally made of stainless steel, and the main processing methods are welding and deep drawing. Among them, for the welding process, due to the large welding deformation of stainless steel materials, it is difficult to control the dimensional accuracy of the sink, which limits the overall shape of the sink body, resulting in a single structure of the sink body, and thus restricting the development of more functional structures of the sink-type washing machine. Subject to such constraints, the structure used to dry dishes in the above-mentioned dishwasher mainly uses a fan to directly blow air into the tank body and then blow it out, relying on the wind speed to achieve convection diffusion under natural conditions, which results in uneven distribution of airflow in the tank body and poor drying effect.

The baffle can be used to set the blowing direction and the reflection direction of the ultraviolet light as needed, thereby improving the efficiency and effect of drying and sterilizing the dishes.

[0047] The driving assembly 3 includes a push rod motor 31, which is arranged outside the plastic vertical barrel 12 and below the receiving groove 120.

[0052] A drainage hole 217 is provided at the bottom of the air collecting box 21 for draining the accumulated water therein, so as to keep the air collecting box 21 dry and free of residual water.

[0053] The air outlet 123 is located on the second side wall 122 of the plastic tub 12 and is arranged opposite to the blowing assembly 2 located on the first side wall 121. The second side wall 122 of the plastic tub 12 gradually arches outward from the edge to the air outlet 123 to form a guide surface 125 for guiding the incoming wind slowly. The above structure can effectively reduce the air flow turbulence caused by the vertical collision between the external exhaust airflow and the side wall of the tank body, so that the external exhaust airflow can flow smoothly along the side wall.

[0054] The air outlet 123 is arranged near the upper part of the second side wall 122 of the plastic barrel 12, and the slope of the guide surface above the air outlet 123 is greater than the slope of the guide surface below the air outlet. This structure cooperates with the lifting and lowering of the air collecting box 21 and the rotation of the baffle 23 as required, which is conducive to improving the drying efficiency and drying effect.

[0055] The air supply assembly 4 includes an air duct 41 and a fan 42. The first end of the air duct 41 is connected to the air outlet 123. The air duct 41 bypasses the second side wall 122 of the plastic tub 12, the bottom of the box, and extends upward along the first side wall 121 of the plastic tub 12. The second end passes through the bottom of the accommodating groove 120 and is connected to the blowing assembly 2. The fan 42 is arranged in the air duct 21 and is used to provide power for forming an internal circulation of wind. The above structure is adopted to form an internal circulation of wind in the washing chamber, and fully utilize air preheating to achieve drying.

[0056] The air duct 41 includes a first section 411 extending upward from its first end, a second section 412 arranged horizontally above the first section 411, a third section 413 connected to the downstream of the second section 412 and extending vertically outside the second side wall 122 of the plastic tub 12, a fourth section 414 extending horizontally close to the bottom wall of the box, and a fifth section 415 connected to the downstream of the fourth section 414 and extending vertically outside the first side wall 121 of the plastic tub 12. The above-mentioned multi-section air duct structure can fully condense the humid hot air and convert it into dry hot air, thereby improving the drying efficiency.

[0057] The fan 42 is disposed in the third section 413 and is arranged near the bottom of the box. A heating element 43 for heating the air is also disposed in the third section 413, and the heating element 43 is disposed below the fan 42. Further heating of the residual hot air after the condensed water is removed is beneficial to improving the drying efficiency and effect.

[0058] The local width of the second section 412 is increased to form a condensation chamber 410, in which a plurality of staggered condensation baffles 416 are arranged. Each condensation baffle 416 is tilted and arranged at intervals in the condensation chamber 410 to form a condensation channel with a louver structure. This structure is conducive to improving the removal effect of water vapor in the humid hot air.

[0059] The bottom wall of the fourth section 414 is provided with an overflow hole 417 for draining condensed water, and at least the bottom of the fourth section 414 located on both sides of the overflow hole 417 gradually slopes downward toward the overflow hole 417 to form a water guide surface 418.

[0060] In this embodiment, a concave water return area 14 is provided at the bottom of the box body 1, and the top of the water return area 14 is covered with a filter plate 15. A spray arm 16 arranged near the top of the water return area 14 is provided in the washing chamber, and a water pumping mechanism 17 for pumping water in the water return area 14 to the spray arm 16 is provided below the water return area 14.

[0061] After washing is completed, the telescopic motor 33 drives the baffle 23 outside the air collecting box 21 to open. If the number of dishes placed in the washing chamber is less than M sets, the telescopic motor 33 drives the baffle 23 to open 30 to 70 degrees relative to the outer wall of the air collecting box 21. If the number of dishes placed in the washing chamber is greater than or equal to M sets, the telescopic motor 33 drives the baffle 23 to open 70 to 90 degrees relative to the outer wall of the air collecting box 21.

[0062] The air supply component 4 is operated. The air supply component 4 extracts the air in the washing chamber through the air outlet 123, and sends the air to the air collecting box 21 after the air supply component 4 removes condensed water and heats the air. The air collecting box 21 moves up and down under the push of the push rod motor 31, and while blowing dry hot air to the tableware, it increases the convection of the air in the washing chamber, and dries the tableware and various parts of the washing chamber;

[0063] While drying the dishes and the washing chamber, the ultraviolet light that moves up and down with the air collecting box 21 and is reflected by the baffle 23 sterilizes and disinfects the washing chamber, especially the dishes;

[0064] The driving component 3 can also control the height of the blowing component 2 and the residence time at the height according to the actual number and position of the tableware, so as to improve the drying effect and drying efficiency.
