Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.

As shown in fig. 1-3, the utility model discloses an air flue structure of airing exhaust, including hollow casing, the casing forms the wind channel, the casing includes condensation zone 1 and diffusion zone 2, condensation zone 1 is the ascending U type of opening, condensation zone 1's one end is the air inlet 11 in wind channel, condensation zone 1's the other end and the transition zone 3's of bending connection, transition zone 3 is the arc structure that the opening is decurrent, transition zone 3's the other end and diffusion zone 2 intercommunication, diffusion zone 2 bottom forms the gas outlet 21 in wind channel, be provided with cooling part 4 in the condensation zone 1, improve humid hot gas's cooling efficiency, transition zone 3's middle part sets up keeps off muscle 5, keep off muscle 5 and transition zone 3's top and set up the opening, so that the gas after the condensation gets into diffusion zone 2 smoothly, and simultaneously, when opening the door body of dish washer, effectively prevent that the condition that the torrent from appearing.

The air flue is arranged from top to bottom relative to the inner container, the air inlet 11 is arranged at the upper end of the air flue, the air outlet 21 is arranged at the lower end of the air flue, a container for collecting condensate water is formed at the bottom of the U-shaped condensation area 1, a water outlet 12 is arranged at the bottom of the U-shaped condensation area 1, and the water outlet 12 is communicated with the inner container through a condensation pipe and used for discharging the condensate water collected in the U-shaped condensation area 1 and discharging the condensate water to the outside of the dishwasher through the inner container.

The condensing part 4 is located at the middle upper part of the U-shaped condensing area 1, as shown in fig. 3, the cooling part 4 is a plurality of salient points arranged on the inner wall of the condensing area 1, and the plurality of salient points are distributed on the front and rear inner walls of the condensing area 1 and are arranged in a staggered manner. The salient point can increase the contact area of fluid and casing to improve the heat transfer volume, can also have slight influence to the fluid route simultaneously, slow down fluid flow and strike, the better effect that plays condensation zone 1.

In another embodiment, the cooling component 4 is a plurality of guiding ribs arranged on the inner wall of the condensation area 1, the guiding ribs can increase the contact area of the fluid and the shell, and the condensation effect is better.

The guide ribs are linear, the guide ribs are arranged irregularly, and each guide rib is of an independent structure.

The direction muscle is the S type curve, and the straight line behind the end to end of many direction muscle is parallel with the inner wall of U type condensation zone 1, when improving condensation efficiency, can not gather the comdenstion water in the assurance direction muscle.

Along the fluid flow direction, the bore of the casing of diffusion zone 2 increases gradually, and the static pressure that reachs diffusion zone 2 through simulation analysis is great, for preventing that long-time accumulation makes the wind channel warp, guarantees the life in wind channel, improves the reliability of wind channel structure of airing exhaust, sets up a plurality of support columns 6 in the casing of diffusion zone 2.

A dish washer comprises an inner container, a door body and the exhaust air channel structure, wherein the door body comprises an inner door and an outer door, an air inlet 11 is formed in the inner door, the exhaust air channel structure is fixed between the inner door and the outer door, and an air outlet 21 is formed in the outer door and is used for discharging residual water vapor after condensation outwards.

The dish-washing machine further comprises a fan, the fan is arranged in the air duct of the air exhaust air duct structure, preferably, an air inlet of the fan is communicated with the inner container, and an air outlet of the fan is communicated with the air inlet 11 of the air duct.

The side wall of the shell of the diffusion area 2 is provided with a fixed seat 7, the fixed seat 7 is provided with a mounting hole, and the shell is fixed on the door body through a bolt.

This air exhaust duct is installed on the dishwasher door body, the vapor content is great in the inner bag after the dishwasher finishes working, the program opens exhaust system and dries the tableware this moment, the fluid that has a large amount of vapor is inhaled in the wind channel by the fan, the fluid at first passes through condensation zone 1, the runner enlarges the heat transfer area between fluid and the wind channel wall through cooling part 4, thereby improve the condensation effect of vapor, cooling part 4 can change the fluid flow path to a certain extent simultaneously, make the fluid at the turbulence degree increase of flow in-process, be favorable to the condensation effect, the wind channel of airing exhaust is vertical state in the drying stage, the comdenstion water that condensation zone 1 collected can be gathered in comdenstion water return opening department under the effect of gravity, flow back to the dishwasher inner bag through the condenser pipe, reduce vapor and discharge to the external environment. And then the fluid enters the residual steam diffusion area 2, the fluid speed is greatly reduced, residual steam in the fluid is gradually diffused and slowly discharged, and the possibility of forming condensed water is reduced, so that the use experience of a user is ensured.

When the dish washer door body is in the open mode completely, the door body is in the level and places the state, if the comdenstion water too much fails in time to flow back totally or when having remaining the comdenstion water from the condenser pipe, because the lower of the door body is turned and is done and probably leads to the comdenstion water to gush into diffusion zone 2 to flow out from gas outlet 21, keep off the emergence of the above problem of design more than can be fine stopping of muscle 5, effectively prevent surging of comdenstion water, make it flow back to the inner bag through the condenser pipe again.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof.
