Description

A lint filter device of a clothes dryer and the clothes dryer

technical field

The present invention relates to the technical field of clothes dryers, in particular to a lint filtering device for clothes dryers and the clothes dryer.

Background technique

Clothes dryers are divided into two types: inline dryers and condensation dryers, according to their exhaust methods. The drying air of the inline dryer is directly discharged into the air after passing through the drum. The drying air of the condensing dryer circulates through the entire air circulation system. No matter what kind of clothes dryer, the drying wind of the clothes dryer will always bring out some fine lint after passing through the clothes in the drum. In order to prevent the lint from being discharged into the air to pollute the air when the dryer exhausts the air, or that the lint circulates in the air circulation system with the drying air and cause more fine lint to be attached to the clothes, the existing clothes dryer needs to Configure a lint filter.

The current lint filter devices are mainly divided into the following two types:

A lint filtering device as shown in Figure 1, including a filter screen installation frame 1, the overall structure is a drawer, one side is completely open, and this side is used as an air inlet for air intake, and a filter is installed on the opposite side of the air inlet. net2. As shown in Figure 2, the air inlet and outlet of the lint filter device, the wind entering from the air inlet is filtered by the filter and then enters the air duct. However, the lint filtering device is installed in a straight or oblique manner. When it needs to be pulled out for lint cleaning, in the process of extracting the lint filtering device, since one side of the lint filtering device is Fully open, lint is easy to fall into the air duct. Therefore, this kind of lint filtering device has poor ability to collect lint, and the lint is very easy to fall into the air duct. The falling lint entering the air duct will not only affect or even damage the drying equipment, but also pollute the external environment or cause secondary pollution to the clothes.

Another lint filtering device as shown in Figures 3, 4 and 5, this kind of lint filtering device is that the lint filter box 3 and the lint filter cover 4 are interlocked with two parts to form a complete line The debris filtering device is box-shaped, with complete filter screens 2 on both sides. The box-shaped filter device solves the problem that the lint dust falls into the air duct during the extraction process of the lint dust filter device. This kind of lint filtering device is placed in the air duct, as shown in Figure 6, the wind with moisture and lint from the drum can only go in from the grid-like air inlet 5 on the top of the lint filtering device, and then from The filter screen 2 goes out, so the air intake can only be limited to the grid-shaped air inlet 5 on the top of the filter device. Relatively speaking, the air intake area is too small, which has an impact on energy consumption or drying effect.

In view of this, the present invention is proposed.

detailed description

A lint filtering device for a clothes dryer and a clothes dryer according to the present invention will be described in detail below in conjunction with the accompanying drawings:

As shown in Figures 7 and 8, a lint filtering device for a clothes dryer includes a filter frame and a filter screen 2, which is in a box-like structure as a whole. The top of the filter frame is provided with a first air inlet 8, and the upper side of the filter frame The second air inlet 9 is set, and the bottom of the filter frame cooperates with the filter screen 2 to form a lint collection bin.

In the present invention, the first air inlet 8 is arranged on the top of the filter frame, and the second air inlet 9 is arranged on the upper side of the filter frame, so that the drying air enters from the top and the side of the filter frame at the same time, which increases the air intake per unit time and improves Improve filtration efficiency, reduce energy consumption, and improve drying efficiency.

The lower part of the lint filter of the present invention has a lint collection bin, and the filtered lint is collected in the lint collection bin, thereby avoiding the occurrence of the lint falling when the lint filter is drawn out.

The filter frame of the present invention includes a first filter frame 6 and a second filter frame 7 that are connected together in relative rotation, so that when the first filter frame 6 and the second filter frame 7 are closed, a box-like structure is formed, and when required When cleaning the filter net 2 in the lint filter device, the first filter frame 6 and the second filter frame 7 can be opened. Therefore, the lint filtering device of the present invention has a better lint collection effect, and is more convenient for users to clean the lint by themselves to ensure the filtering effect.

The first air inlet 8 of the present invention is arranged on the top of the first filter frame 6 and/or the second filter frame 7, and the second air inlet 9 is arranged on the side upper part of the first filter frame 6 or the second filter frame 7, The side lower parts of the first filter frame 6 and the second filter frame 7 cooperate with the filter screen 2 to form a lint collection bin.

Specifically, the second air inlet 9 is arranged on the upper side of the second filter frame 7, the lower side of the second filter frame 7 is provided with a filter screen 2, and the entire side of the first filter frame 6 is provided with a filter screen 2.

The second air inlet 9 on the top of the second filter frame 7 of the present invention can increase the air intake per unit time, therefore, the area of the second air inlet 9 can be set as large as possible. The filter screen 2 is arranged on the second filter frame 7 at the lower part of the second air inlet 9 of the present invention, so as to realize the filtering effect on the wind, increase the air output of the lint filtering device, and improve the filtering efficiency.

Simultaneously, between the second filter frame 7 of the second air inlet 9 bottom, the bottom of the first filter frame, and the filter screen 2, a lint collection bin is formed, and if the area of the second air inlet 9 is too large, it will cause lint collection. The volume of the bin is too small, which requires frequent cleaning of lint. Therefore, the area of the second air inlet 9 of the present invention should occupy less than 2/3 of the entire area of the second filter frame 7, so that the air intake of the lint filter device can be guaranteed, and the lint dust in the lint dust collection bin can be guaranteed. collection volume.

Therefore, the middle part of the side of the second filter frame 7 according to the present invention is provided with a transverse rib 10, and the second air inlet 9 is formed between the transverse rib 10 and the upper frame of the second filter frame 7, and the transverse rib 10 and the upper frame of the second filter frame 7 An installation frame for installing the filter screen 2 is formed between the lower frames of the second filter frame 7 .
