Description

Air inlet pipe and washing equipment using the air inlet pipe

【Technical field】

The utility model relates to an air inlet pipe for leading air into a condensing device and washing equipment using the air inlet pipe.

【Background technique】

Existing washing equipment with a drying function includes a clothes dryer and a washer-dryer integrating washing and drying functions. The drying process is generally as follows: under the action of the heating device, the dry air is heated into dry hot air in the heating pipe, and then enters the washing tub to exchange heat with the wet clothes in the washing tub, and the moisture in the clothes Take it away to form relatively humid hot air, and then enter the condensing device through the outlet set on the washing bucket. After the condensation of the condensing device, the moisture in the relatively humid hot air is condensed into water, and then discharged through the drain pipe. The condensed air becomes relatively dry cold air, which is reintroduced into the heating tube under the action of the fan, and becomes dry hot air after heating, which enters the next cycle, and so on, until the drying process ends.

Common condensation methods include condensate condensation and air condensation. Regardless of whether it is a condensing device that uses condensed water or air condensation, the condensing device is generally directly connected to the exhaust port of the washing tub through a bellows, although the bellows can largely slow down the washing tub assembly during operation. Vibration and impact caused by high-speed rotation, but the air it introduces is very uneven, which affects the condensation effect of the condensing device to a certain extent. In addition, because the clothes will inevitably produce many lint or other Impurities (hereinafter referred to as lint), the lint will be directly brought into the condensing device with the humid hot air and adhere to the surface of the condensing device to affect the condensation effect or block the entire air circulation channel. What's more, the lint Under the action of the fan, it will be brought into the fan or even the heating pipe and attached to the surface of the fan or heating pipe, thereby causing greater danger. Although a filter device can be set before the hot humid air enters the condensing device to filter out the lint mixed in the air, because the exhaust port of the washing tub is usually arranged at the bottom near the rear of the washing tub, the limitation of its location makes Cleaning and replacement of the filter unit is extremely difficult.

【Content of invention】

In view of the above problems, the purpose of this utility model is to provide an air inlet pipe, which can lead the air into the condensing device relatively uniformly.

The above purpose is achieved by the following means: an air inlet pipe, which communicates with a condensing assembly, includes an air inlet, a pipe body and an air outlet, and air is introduced into the pipe body through the air inlet and then circulates through the air outlet In the condensing assembly, the air inlet is arranged at one end of the pipe body, the other end of the pipe body is closed, and the air outlet is arranged at the top of the pipe body along the longitudinal direction of the pipe body . By designing the air outlet as an opening in the longitudinal direction to match the condensing assembly, the air introduced by the air inlet flows relatively evenly to the condensing assembly, thereby ensuring the condensation effect of the condensing assembly .

Preferably, the bottom of the pipe body is inclined upward at a certain angle from one end provided with the air inlet to the other end. In this way, through the condensation effect of the condensing component, the moisture contained in the humid hot air is condensed and a small amount of water flowing in from the air inlet will accumulate in the relatively low position of the pipe body, and the airflow will Under the action, the accumulated water is blown up and rolled, thereby filtering the lint contained in the air, thereby effectively preventing the lint from entering the condensation assembly.

Preferably, an outlet extends downwards from a proper position of the bottom, and when the water accumulated inside the pipe body is too much, it will be discharged through the outlet.

Preferably, the outlet is set in the middle of the pipe body, so as to ensure a certain distance between the outlet and the air inlet, so that the water accumulated inside the pipe body is as close as possible to the air inlet. position, thereby improving the filtering effect on fluff contained in the air.

Another object of the present utility model is to provide a washing device with a drying function, so as to effectively ensure its drying efficiency.

The above object is achieved in the following way: a washing device with a drying function, comprising an air circulation loop composed of a heating assembly, a washing tub assembly, a condensation assembly and a fan assembly, characterized in that: the washing tub assembly is connected to the The air inlet pipe according to the utility model is connected between the condensing components, thus, the dry air is heated in the heating component to become dry hot air and then is introduced into the washing tub assembly and placed in the washing tub assembly The clothes in the interior undergo heat exchange, so that the moisture contained in the clothes is taken away, forming hot humid air, which is then introduced into the condensing component through the air inlet pipe, and the humid hot air is The moisture contained in it is condensed into water and accumulates at the bottom of the air inlet pipe together with the condensed water used for condensation or the water used to wash the condensing components. After the condensation of the condensing components, the heat of the damp The air becomes dry air with a relatively low temperature, then is sucked into the heating assembly by the blower assembly to be reheated, and then introduced into the washing tub assembly to enter the next cycle. When the humid hot air passes through the air inlet pipe, the airflow will blow and roll the water accumulated at the bottom of the air inlet pipe, thereby filtering the lint contained in the air. When the accumulated water exceeds the outlet where the When the height is high, the water filtered with lint flows into the washing bucket through the outlet, and then is discharged through the drainage system of the washing equipment. Of course, excess water can also flow back into the washing tub through the air inlet, and then be discharged through the drainage system of the washing equipment, so that the humid hot air can be effectively filtered by water before being introduced into the condensing assembly, wherein The mixed lint is filtered, which effectively prevents the lint from being brought into the condensing assembly, fan assembly, heating assembly and the entire air circulation circuit by the air, thus ensuring the condensation effect of the condensing assembly and the entire air circulation The smoothness of the circuit further effectively guarantees the overall drying efficiency of the washing equipment.

Preferably, the condensing component adopts air condensing to save the water used by the washing equipment in the washing or drying process.
