Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a dishwasher with a double-air structure. Background Art

[0002] With the advancement of technology and the improvement of living standards, especially the rapid development of home appliances, specialized dishwashing equipment has emerged for cleaning dishes. Dishwashers generally have functions such as spraying, drying, and sterilizing. Users simply place dishes and other tableware into the dishwasher, which automatically completes a series of cleaning tasks according to user settings. Their ease of use and fully automated operation effectively reduce user effort, making dishwashers increasingly popular among users.

[0003] Dishwashers currently on the market undergo prolonged main wash and rinse heating, coupled with a spray-type spray arm, which continuously impacts the dishes and the dishwasher's inner tank with heated water. After washing, the inner tank of the dishwasher is exposed to high temperature and high humidity, which is very unfavorable for drying the dishes and long-term storage and preservation. Prolonged storage in a humid environment can easily breed bacteria in the dishes in the dishwasher, causing sanitation problems and reducing user satisfaction with the dishwasher. Therefore, conventional dishwashers generally have a drying function, which is primarily achieved through a drying device comprising a fan and a heater. This device heats the airflow generated by the fan to form warm air, which is then fed into the inner tank, effectively drying the dishes.

[0004] However, existing dishwashers are typically completely sealed to prevent water leaks, foreign objects from entering, and heat preservation. This results in a rudimentary steam exhaust mechanism, which can lead to high pressure inside the dishwasher. As dishes are dried, the expansion of the steam inside the dishwasher can easily push the door open, affecting the drying process and causing damage to the dishwasher, rendering it inoperable.

[0005] Therefore, a dishwasher with a dual-air structure is proposed to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the present utility model is to provide a dishwasher with a dual-wind structure, which can reduce the air pressure in the inner tank and achieve a better drying effect.

[0007] The technical solution adopted by the utility model to solve the problem is: a dishwasher with a double-wind structure, comprising a main body, wherein the main body is provided with an inner tank with a front end opening and a door body rotatably connected to the main body; an air inlet is provided on the inner side wall of the inner tank, and an air inlet device is provided on the outer side wall of the inner tank, the air inlet device is connected to the air inlet, and the air inlet device is used to transport gas into the interior of the inner tank; an air outlet is provided on the inner side wall of the door body, and an exhaust device is provided in the door body, the exhaust device is connected to the air outlet, and the exhaust device is used to discharge the gas inside the inner tank to the outside of the dishwasher.

[0008] As a further improvement of the above technical solution, the exhaust device includes a shell, a fan is arranged in the shell, a first exhaust port is arranged at the inner end of the shell, the first exhaust port is connected to the air outlet, the air outlet end of the shell is connected to a vertically arranged condensation chamber, and a second exhaust port is arranged at the bottom of the condensation chamber, and the second exhaust port is connected to the outside world.

[0009] As a further improvement of the above technical solution, there is a gap between the bottom of the door body and the main body, the gap is connected to the outside, and the second exhaust port is arranged in the gap.

[0010] As a further improvement of the above technical solution, the air inlet device includes a blower and an air outlet channel, the air outlet end of the blower is connected to the air inlet end of the air outlet channel, and the air outlet end of the air outlet channel is connected to the air inlet.

[0011] As a further improvement of the above technical solution, a heating device is provided in the blower.

[0012] The beneficial effect of the present invention is that when in use, after the dishwasher has cleaned the dishes in the inner tank, the interior of the inner tank is filled with water vapor, and the internal air pressure is relatively high. At this time, the exhaust device will be started to discharge the water vapor in the inner tank to the outside of the dishwasher, or the air intake device will be started to transport dry gas to the interior of the inner tank. The water vapor is discharged from the exhaust device through the gas, so that the internal air pressure of the inner tank is reduced, thereby achieving the effect of drying the interior of the inner tank, which can prevent the internal air pressure of the inner tank from being too high and thus pushing open the door of the dishwasher, and at the same time can reduce the drying time, have a good drying effect, and can provide users with a good usage experience.
