[0002] Dish washer is the kitchen helper of family and enterprise, and is used for the equipment of automatic washing dish, chopstick, plate, dish, knife, fork and other tableware to help people reduce housework burden.
[0003] With the gradual popularization of dish washer, dish washer is more and more loved by consumers, and the demand of consumers for dish washer with washing, drying and sterilizing functions is more and more outstanding. But the traditional dish washer mainly makes the heated water impact tableware and dish washer inner container through spraying arm by long time washing and heating. After washing, the dish washer inner container is in high temperature and high humidity environment, which is not conducive to the drying of tableware and the long time storage of tableware. And in the humid environment, long time placement makes the tableware in the dish washer easy to breed bacteria and virus, which easily leads to the spread of disease.
[0004] At present, the dish washer with air draft function on the market is embedded dish washer, sink dish washer and table type dish washer, and the air inlet and outlet parts of air draft are generally installed on the two side walls of the dish washer cavity. In order to ensure the capacity of the internal cavity, the overall size of the machine can only be increased, especially for small dish washers. Increasing the overall size makes the whole machine look very bloated and not beautiful. And the high temperature and high humidity gas extracted by the air draft machine is discharged to the rear of the cabinet, which is easy to cause the cabinet to be damp and mildew. Some are set at the lower outlet, which is also easy to cause the floor to be damp, so further improvement is needed.
[0005] In summary, at present, a door body air draft drying assembly of dish washer with compact structure and dry surrounding environment is needed. UTILITY MODEL CONTENTS

[0007] In order to realize the above purpose, the utility model adopts the following technical scheme:
[0008] The door body air-drying assembly of the dishwasher comprises a machine door, an air fan shell is fixed inside the machine door, an air inlet channel, an air extraction channel and an air outlet channel are arranged inside the air fan shell, one end of the air inlet channel is arranged on the inner wall of the machine door, a partition plate is further fixed inside the air fan shell, the air inlet channel and the air extraction channel are both arranged on one side of the partition plate and are both arranged close to the inner wall of the machine door, the air outlet channel is arranged on the other side of the partition plate and is arranged close to the outer wall of the machine door, a partition rib is fixed on the partition plate, the air inlet channel and the air extraction channel are arranged on the two sides of the partition rib respectively, a ventilation opening is arranged on the partition rib, the other end of the air inlet channel and one end of the air extraction channel are connected through the ventilation opening, a blower fan is further arranged on the partition plate, the other end of the air extraction channel and one end of the air outlet channel are connected through the blower fan, and the other end of the air outlet channel is arranged on the outer wall of the machine door.
[0009] The air inlet channel, the air extraction channel and the air outlet channel are all integrated in the same air fan shell in a staggered distribution manner, so that the compactness is greatly improved. When the blower fan works, the hot and humid air inside the machine body liner is directly extracted to the outside of the dishwasher through the air inlet channel, the ventilation opening, the air extraction channel and the air outlet channel in sequence, so that the drying speed of the tableware is improved. The air fan shell is arranged on the machine door to discharge steam, so that the furniture around the dishwasher is not dampened by the hot and humid air, and the dryness of the environment around the dishwasher is well maintained. The air extraction channel and the air inlet channel are arranged in a staggered and isolated manner, so that the washing water is prevented from being directly sprayed into the blower fan through the air inlet channel, thereby protecting the blower fan.
[0010] Preferably, an air inlet is arranged on the inner wall of the machine door, one end of the air inlet channel is arranged at the air inlet, an air exhaust window is arranged on the outer wall of the machine door, the other end of the air outlet channel is arranged at the air exhaust window, the air inlet is arranged at the bottom of the air inlet channel and below the blower fan, and one end of the air inlet channel is provided with a backflow inclined surface corresponding to the air inlet. When the blower fan works, the hot and humid air inside the machine body liner is extracted into the air fan shell through the air inlet on the inner wall of the machine door, and is sequentially conveyed to the air exhaust window on the outer wall of the machine door through the air inlet channel, the ventilation opening, the air extraction channel and the air outlet channel, and is finally discharged through the air exhaust window. The air inlet is arranged below the blower fan, so that the water flowing into the bottom of the air inlet channel after the machine door is opened is prevented from flowing onto the blower fan, and the water can be directly backflowed into the machine body liner after the machine door is closed, thereby protecting the blower fan; the backflow inclined surface corresponding to the air inlet is arranged at the bottom of the air inlet channel, so that the washing water can be quickly backflowed into the machine body liner.
[0011] As preferred, one end of the air inlet channel is fixed at the air inlet by a fan nut, and the other end of the air outlet channel is fixed at the air exhaust window by a screw.
[0012] As preferred, the air vent is located at the top of the isolation rib, the bottom of the isolation rib is further provided with a backflow port, the air blower is located above the backflow port, and the bottom of the air suction channel and the bottom of the air inlet channel are connected through the backflow port. Through the design of the bottom backflow port, the condensed water in the air suction channel of the air blower can be directly returned to the machine body inner container.
[0013] As preferred, the air inlet channel is internally fixed with a convex rib between one end of the air inlet channel and the other end of the air inlet channel. Through the design of the convex rib, the rising humid hot air can be condensed to form liquid water flowing downward and quickly returning to the machine body inner container under the guidance of the backflow slope at the bottom of the air inlet channel.
[0014] As preferred, the partition plate is further provided with a side air port, and the other end of the air inlet channel and the other end of the air outlet channel are connected through the side air port. Through the design of the side air port, when the air blower is not working, the humid hot gas can directly run out of the air exhaust window, preventing direct impact on the air blower.
[0015] The utility model discloses the beneficial effect is: improve the compactness of structure;Improve the drying speed of tableware;Maintain the dryness of the environment around the dish-washing machine;With the effect of protecting the air blower. BRIEF DESCRIPTION OF DRAWINGS
