Problems solved by technology

However, the position away from the drying air inlet or the axis of the drum is low in temperature, and the drying air is not easy to enter and difficult to dry; the entangled clothes are also more likely to be rolled near the axis of the drum, making it difficult to dry
[0004] In order to solve the above problems, scientific and technological workers have made some improvements to the existing clothes dryers. The prior art provides a control method for clothes dryers. , the rotation speed of the single rotation direction of the drying barrel is periodically changed from the norm

Embodiment approach 1

[0036] A method of improving the drying effect of clothes by changing the speed of the drum, such as figure 1 , figure 2 As shown, the method includes the following stages:

[0037] Weighing stage 101: in the initial stage of drying, the weight of the dried clothes is determined;

[0038] Drying early stage 102: In the early drying stage, the clothes are relatively damp, and the drum rotates at a speed at which the clothes are not easy to accumulate on the wall of the drum (the speed is 40-60 r / min);

[0039] Post-drying stage 103: In the post-drying stage, according to the unit weight of the clothes measured in step A, the drum is controlled to rotate in the same direction or rotate forward and reverse at a periodically changing speed, and the periodically changing speed includes at least two different Rotating speed;

[0040] Clothes cooling stage 104: a process of cooling clothes after drying.

[0041] In the early stage of drying 102 and the clothes cooling stage 104,...

Embodiment approach 2

[0050] In this embodiment, the drying stage 202, the weighing stage 201, and the clothes cooling stage 204 are the same as the control method for the drum in the first embodiment, for example Figure 4 As shown, the difference from Embodiment 1 is that the method of changing the rotation speed of the drum in the later stage of drying 203 is different. In this embodiment, a change period of the drum's periodically changing rotation speed is: the drum first accelerates to rotate to the first rotation speed , and rotate forward at the first speed for a period of time and then accelerate to the second speed, after rotating forward at the second speed for a period of time, decelerate and rotate in reverse, after the reverse rotation first accelerate to the first speed, and then rotate at the first speed After the rotation speed is reversed for a period of time, it is accelerated to the second rotation speed and reversely rotated for a period of time at the second rotation speed. The...

Embodiment approach 3

[0052] In this embodiment, the drying stage 302, the weighing stage 301, and the clothes cooling stage 304 are the same as the control method for the drum in the first embodiment, as shown in Figure 5 As shown, the difference from Embodiment 1 is that the method of changing the rotation speed of the drum in the post-drying stage 303 is different. In this embodiment, a change cycle of the periodically changing rotation speed of the drum is: the drum first accelerates to rotate to the highest speed , and after rotating at the highest speed for a period of time, decelerate and reverse the rotation, accelerate to rotate to the highest speed after reversing, and rotate at the highest speed for a period of time. In this way of changing the rotation speed of the drum, since the drum rotates in a single way, the control of the drum is relatively simple, but the drying effect on clothes is greatly improved compared with that of the existing clothes dryer.

[0053] The change period of...

Abstract

The invention discloses a method for improving drying effect of clothes through speed change of a roller and a clothes drying machine. The method comprises the following steps of: at a primary stage of drying, detecting the weight and/or unit weight of the clothes to be dried; at an earlier stage of drying, due to the fact that the clothes are relatively moist, rotating the roller based on the speed enabling the clothes to uneasily accumulate to a roller wall; at a later stage of drying, controlling the roller to rotate towards the same direction or forwards and backwards rotate alternately according to the periodically changed rotating speed based on the corresponding relation of the weight and/or the unit weight of the clothes and the rotating speed of the roller, wherein the periodically changed rotating speed at least comprises two different kinds of rotating speed; and a process of cooling the dried clothes, according to the method, controlling the roller to rotate towards the same direction or forwards and backwards rotate alternately according to the periodically changed rotating speed by measuring the weight and/or the unit weight of the clothes, and the corresponding relation of the weight and/or the unit weight of the clothes and the rotating speed of the roller, so that the clothes can be completely extended to realize the uniform and complete drying effect of the clothes and further improve the drying effect of the clothes with large weight.

Description

technical field [0001] The invention relates to the technical field of clothes drying, in particular to a method for improving clothes drying effect by changing the speed of a drum and a clothes dryer. Background technique [0002] In the process of drying clothes in the existing clothes dryer, when the drum rotates in the same direction, the rotating speed is constant. When drying a large amount of clothes, the clothes become fluffy and bulky as the clothes dry. In this case , Clothes that are not completely dry will be crowded, and it is difficult for high-temperature and dry air to enter the inside of the clothes, which will cause slow drying speed. [0003] At the same time, during normal drying, the clothes near the drying air inlet are easy to dry due to the high temperature of the contact air, but the clothes far away from the drying air inlet or near the drum axis are not easy to dry; , the clothes in the upper part of the drum are also fluffier than the clothes in ...
