Description

Water tank with draining function and cleaning machine using same Technical Field The invention relates to the field of water tanks, in particular to a water tank with a draining function and a cleaning machine using the same. Background A draining table is generally disposed on the water tank, so that the washed tableware, food and the like can be placed on the draining table for draining, for example, chinese patent No. ZL202422664162.7 (issued to CN 223433903U) discloses a water tank, which includes a tank body, a draining table and a shelf, wherein the draining table is slidably disposed in the tank body along a first horizontal direction and detachably connected with the tank body, the draining table is smaller in size than the tank body along the first horizontal direction, the shelf is slidably disposed in the tank body along a second horizontal direction and detachably connected with the tank body, and the shelf is smaller in size than the tank body along the second horizontal direction, one of the first horizontal direction and the second horizontal direction is a longitudinal direction of the tank body, and the other is a transverse direction of the tank body. Such as chinese patent No. ZL202321200484.5 (issued notice No. CN 219671542U). However, the existing draining tables only rely on the gravity action of water to drain, so that the draining efficiency is low, and water stains are easy to remain on the draining tables after use, so that dirtying or mildewing is caused. Disclosure of Invention The invention aims to provide a water tank with a draining function, which is high in draining efficiency and good in draining effect. The second technical problem to be solved by the invention is to provide a cleaning machine applying the water tank aiming at the prior art. The third technical problem to be solved by the invention is to provide a cleaning machine which uses the water tank and can clean a draining device aiming at the prior art. The water tank with the draining function comprises a tank body with a water falling port and a draining device, and is characterized in that the draining device is detachably hung on the upper part of the tank body along the horizontal direction and comprises a draining table, a diversion channel and a centrifugal fan, wherein the draining table is used for placing objects to be drained; The draining table is arranged at the top of the draining device along the horizontal direction, and vertically penetrating draining holes are arranged on the draining table; The diversion channel is vertically arranged below the draining table, the upper port of the diversion channel is in fluid communication with each draining hole of the draining table, and the lower port of the diversion channel is in fluid communication with the air inlet of the centrifugal fan and the water outlet of the tank body. Further, the top of the draining table is provided with an object placing surface for placing objects to be drained, the height of the object placing surface is higher than that of each draining hole, An air chamber is arranged in the draining table, the air chamber is provided with an air outlet capable of outputting air along the horizontal direction, In addition, in the draining state, the object to be drained is placed on the object placing surface, and the air flow blown out from the air outlet can flow between the object to be drained and the draining hole. Under the action of negative pressure of the centrifugal fan, the objects to be drained (such as vegetable leaves and the like) can shield the draining holes to influence draining, and in order to avoid the situation, the invention prevents the draining holes from being shielded by arranging the object placing surface higher than each draining hole and blowing the objects to be drained by utilizing the air outlet of the air chamber. Further, the object placing surface comprises a first object placing surface, supporting plates are arranged on the top surface of the draining table at intervals, each supporting plate extends vertically and is staggered with each draining hole, and the top edge of each supporting plate forms the first object placing surface. Through setting up each backup pad, can realize treating the firm support of waterlogging caused by excessive rainfall thing on the one hand to make first object face higher than each waterlogging caused by excessive rainfall hole, leave the clearance between each backup pad on the other hand, and stagger each other with each waterlogging caused by excessive rainfall hole and set up, can make the hydroenergy that drips out flow into each waterlogging caused by excessive rainfall hole more fast like this. Further, each supporting plate is a square plate, the number of the supporting plates corresponding to each draining hole is four, and the four supporting plates are respectively located at each side of the corresponding draining hole and are arranged in a square array
