Referring to fig. 1 and 2, the dishwasher includes a dishwasher body 2, a pedestal 3, and a breather 4.

The dishwasher body 2 may be a table dishwasher, a cabinet dishwasher, an embedded dishwasher, etc., and is not limited herein. The dishwasher body 2 comprises a washing chamber 21 bounded by inner walls, and when in use, dishes to be washed are placed in the washing chamber 21 for washing.

The base 3 is arranged at the bottom of the dishwasher main body 2, the base 3 comprises a base 3 cavity with built-in electric components (such as a heater, a motor and the like), the structure of the base 3 is different for different types of dishwasher main bodies 2, and the structure is not limited, for example, for a table type dishwasher, a raised pillar is formed below the base 3 cavity, so that the table type dishwasher is convenient to be placed on other planes; for an embedded dishwasher, the chamber wall of the base 3 may also be enclosed by the mounting plane of the embedded dishwasher.

The breather 4 is disposed outside the washing chamber 21, and fig. 1 shows the breather 4 disposed on the outer surface of the left side of the washing chamber 21 by way of example, but the present invention is not limited thereto, and the breather 4 disposed on the outer surface of any side of the washing chamber 21 is applicable to the present invention. The breather 4 includes at least a communication port 411 and an exhaust port 412, and a steam flow path (air duct) between the communication port 411 and the exhaust port 412. Wherein, the communication port 411 is communicated with the washing chamber 21, and the exhaust port 412 is communicated with the exhaust air duct 31 of the base 3, so that the washing chamber 21 and the base 3 are in gas communication via the breather 4, and the pressure inside and outside the washing chamber 21 of the dishwasher is balanced.

It is worth mentioning that, compared to the prior art, the base 3 of the dishwasher provided in the present embodiment includes the exhaust air duct 31 and the branch passage 32 disposed at the downstream side of the exhaust air duct 31, wherein the exhaust air duct 31 is formed as an air duct space independent from the chamber of the base 3, wherein the positional relationship of the exhaust port 412 and the flow dividing passage 32 in the exhaust air duct 31, and the diversion manner of the diversion channel 32 is not limited herein, it will be understood by those skilled in the art that the exhaust duct 31 serves as an independent duct space, and the condensed gas and the condensed water are discharged by shunting through the shunting channel 32, so that the effects of exhausting gas to the base 3 and preventing the condensed gas from being directly discharged into the base 3 can be realized, technicians can select different use scenes, the positional relationship between the exhaust port 412 and the flow dividing passage 32 in the exhaust air duct 31 and the flow dividing manner of the flow dividing passage 32 are selectively changed. For example, in some preferred embodiments, the exhaust port 412 and the diversion channel 32 may be arranged along the gravity direction, so that the condensed gas and the condensed water flowing out of the exhaust port 412 flow into the diversion channel 32 for separation under the action of gravity, and in other preferred embodiments, the diversion channel 32 may be arranged along the gravity direction in a layered manner by utilizing the characteristic that the gas and the liquid have different densities and the layering phenomenon occurs in the gravity direction for diversion.
