[0003] Based on this, it is necessary to provide a converging air duct structure, a condensing device and a dishwasher to address the problems of complex structure and low condensing efficiency of the condensing device.

[0004] A converging air duct structure comprises: an intermediate body, the intermediate body being provided with a first air inlet; a bottom cover, the bottom cover being arranged on the intermediate body, the bottom cover and part of the intermediate body being adapted to form a first channel, the first air inlet being connected to the first channel; an upper shell, the upper shell being arranged on the intermediate body, the upper shell and part of the intermediate body being adapted to form a second channel and a converging channel, the first channel and the second channel being connected to the same end of the converging channel, the upper shell being provided with an air inlet connected to the second channel, the air inlet being used to be connected to a washing chamber.

[0005] The present application discloses a converging air duct structure, in which a first channel is formed by the cooperation of a bottom cover and an intermediate body, and an upper shell and an intermediate body are adapted to form a second channel and a converging channel. The intermediate body is a part of the first channel, the second channel and the converging channel, making the converging air duct structure more compact. The first air inlet is connected to the first channel, and a fan is installed at the first air inlet so that the external air flow can be introduced from the first air inlet to the first channel, and then merged into the converging channel. There is high-temperature steam in the washing chamber, so that the air inlet and the washing chamber are circulated, and the high-temperature steam will enter the second channel from the air inlet, and finally merge into the converging channel. The dry air that merges from the first channel into the converging channel mixes with the high-temperature steam in the converging channel to form condensed water. The middle body, the bottom cover and the upper shell cooperate to form a compact air duct structure, which speeds up the speed of mixing dry air and wet air to form condensed water, making the condensation effect better.

[0006] In one embodiment, the intermediate body includes an intermediate body and an air guide, the air guide is arranged on the intermediate body and is located on a side facing the upper shell, an air guide side plate is formed on one side of the intermediate body, an air guide channel is formed between the air guide and the air guide side plate, the upper shell cover is arranged on the intermediate body and the air guide, and the upper shell, the intermediate body and the air guide cooperate to form the second channel, and the air guide is used to guide the wind flow. By forming an air guide channel between the air guide and the air guide side plate, the inner diameter of the channel through which the steam flows is relatively small, which can accelerate the flow speed of the steam. The upper shell, the intermediate body and the air guide cooperate to form the second channel, and the air guide can guide the steam input into the second channel from the air inlet, so that the steam can quickly flow from the second channel into the confluence channel and mix with the dry air in the confluence channel to form condensed water.

[0007] In one embodiment, the middle body and / or the upper shell are provided with a plurality of condensation protrusions, and the plurality of condensation protrusions are located in the confluence channel. By densely distributing the plurality of condensation protrusions on the inner side of the middle body and the upper shell, the contact area in the confluence channel is expanded, the speed at which dry and wet air mix to form condensed water in the confluence channel is accelerated, and the condensation effect is better.

[0008] In one embodiment, it also includes a first fan, the intermediate body and the bottom cover are partially adapted to form a first fan accommodating chamber, the first air inlet is connected to the first fan accommodating chamber, the first fan is arranged on the intermediate body and is located in the first fan accommodating chamber, the air inlet end of the first fan is arranged opposite to the first air inlet, and the air outlet end of the first fan, the first channel and the confluence channel are sequentially connected. By installing the first fan in the first fan accommodating chamber, the first fan can be started to pump the external dry airflow from the first air inlet into the first channel. After the dry airflow merges into the confluence channel, it mixes with the steam merged from the second channel into the confluence channel to form condensed water. The confluence air duct has a compact structure, which can quickly mix dry and wet air and form condensed water, so that the condensation effect is better.

[0009] In one of the embodiments, it also includes an anti-backflow baffle, a connecting protrusion is provided on the middle body, the connecting protrusion is located in the first channel, one end of the anti-backflow baffle is rotatably set on the connecting protrusion, and the anti-backflow baffle has at least a first state and a second state. When the anti-backflow baffle is in the first state, the end of the anti-backflow baffle away from the connecting protrusion is separated from the inner side wall of the first channel, so that the first air inlet is connected to the first channel; when the anti-backflow baffle is in the second state, the end of the anti-backflow baffle away from the connecting protrusion is fitted with the inner side wall of the first channel, and the anti-backflow baffle separates the first air inlet from the first channel. By installing an anti-backflow baffle in the first channel, the anti-backflow baffle can rotate relative to the connecting protrusion of the middle main body, and the anti-backflow baffle has at least a first state and a second state according to the start and stop of the first fan. When the first fan is started, the anti-backflow baffle is blown up and separated from the inner wall of the first channel, so that the wind output by the first fan can flow through the first channel. When the first fan is not started, the anti-backflow baffle naturally hangs down to separate the first channel and the first air inlet, thereby preventing the steam in the converging air duct structure from flowing through the first fan accommodating chamber, damaging the first fan, and shortening the service life of the first fan.

[0010] In one embodiment, the anti-backflow baffle is a long strip baffle, and an adaptation hole is provided at one end of the anti-backflow baffle, and the adaptation hole is adapted to the connecting protrusion on the intermediate body. The anti-backflow baffle can rotate relative to the connecting protrusion, thereby switching to the first state or the second state. The anti-backflow baffle is installed on the connecting protrusion on the middle body through the adapter hole on the anti-backflow baffle, and the anti-backflow baffle can rotate relative to the connecting protrusion on the middle body. The anti-backflow baffle will switch to the first state or the second state with the start and stop of the first fan. When the first fan is started, the anti-backflow baffle is blown to fit the inner wall of the first channel. At this time, the anti-backflow baffle is in the first state, so that the wind output by the first fan can enter the first channel; when the first fan stops working, the anti-backflow baffle switches from the first state to the second state, and the anti-backflow baffle naturally hangs down at this time. The end of the anti-backflow baffle away from the adapter hole abuts against the inner wall on the other side of the first channel, separating the first channel from the first fan accommodating chamber, preventing the steam in the converging air duct structure from flowing through the first fan accommodating chamber and damaging the first fan. The simple structure of the anti-backflow baffle switching state with the start and stop of the first fan makes the overall structural design of the converging air duct structure simpler, and can effectively protect the first fan and extend the service life of the device.

[0038] The present application discloses a converging air duct structure, wherein the bottom cover 2 cooperates with the middle body 1 to form the first channel 102, the upper shell 3 and the middle body 1 are adapted to form the second channel 103 and the converging channel 104, and the middle body 1 is used as a part of forming the first channel 102, the second channel 103 and the converging channel 104, so that the converging air duct structure is more compact. The first air inlet 101 is connected with the first channel 102, and a fan is installed at the first air inlet 101 so that the external air flow can be introduced from the first air inlet 101 to the first channel 102, and then merged into the converging channel 104. There is high-temperature steam in the washing chamber, so that the air inlet 301 is circulated with the washing chamber, and the high-temperature steam will enter the second channel 103 from the air inlet 301, and finally merge into the converging channel 104, and the dry air merged from the first channel 102 to the converging channel 104 is mixed with the high-temperature steam in the converging channel 104 to form condensed water.

By forming an air guide channel between the air guide 12 and the wind guide side plate, the inner diameter of the channel through which the steam flows is relatively small, which can accelerate the speed of steam flow. The upper shell 3, the middle main body 11 and the air guide 12 cooperate to form a second channel 103. The air guide 12 can guide the steam input into the second channel 103 from the air inlet 301, so that the steam can quickly flow from the second channel 103 into the confluence channel 104 and mix with the dry air in the confluence channel 104 to form condensed water.

The plurality of condensation protrusions 31 are densely distributed on the inner side of the middle body 1 and the upper shell 3, thereby expanding the contact area in the confluence channel 104, accelerating the speed at which dry and wet air are mixed in the confluence channel 104 to form condensed water, and achieving a better condensation effect.
