Description

Technical Field

[0001] This utility model relates to the field of clothing processing technology, and in particular to a clothing drying device. Background Technology

[0002] In existing technologies, clothes drying equipment such as dryers or washer-dryer combos usually have lifting ribs on the inner wall of the inner drum. As the inner drum rotates, the clothes are pulled up and thrown down with the rotation of the inner drum. This cycle is repeated to keep the clothes moving and to exchange heat with the hot air, ultimately achieving the effect of drying the clothes.

[0003] However, since the height of the lifting ribs in existing clothes drying equipment is usually fixed and cannot be changed according to the actual drying process, if the height of the lifting ribs is too low, it may not be able to lift all the clothes to the highest point inside the drum, resulting in the clothes not being able to fully unfold, reducing the drying rate and increasing the wrinkles of the clothes; when the height of the lifting ribs is too high, in the early stage of drying, it will cause the clothes to be lifted to the highest point inside the drum and fall down, increasing the vibration of the inner drum, drying noise and wear and tear on the clothes.

[0004] To solve the above-mentioned technical problems, Chinese utility model patent with patent number ZL202323412771.5 (authorization announcement number CN222349333U) discloses a lifting rib and clothing processing device. The lifting rib includes a lifting rib body, which includes a first lifting part and a second lifting part arranged side by side, and a connecting part connecting the first lifting part and the second lifting part. Along the direction from the first end to the second end of the lifting rib body, the top height of the first lifting part gradually decreases, and the top height of the second lifting part gradually increases.

[0005] Although the aforementioned garment handling equipment can improve the lifting effect and facilitate the shaking of garments by modifying the structure of the lifting ribs, making it easier for the ribs to catch the garments and lift them to a higher position, it has the following limitations: Since the garment handling process is uncontrollable, it is impossible to predict whether the garments will come into contact with the first or second lifting part of the lifting ribs, thus limiting the lifting effect. Therefore, further improvements to the existing technology are needed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a clothes drying device that can control the height of the lifting ribs to improve the clothes processing effect, in contrast to the above-mentioned prior art.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a clothes drying device, comprising:

[0008] Inner cylinder;

[0009] The lifting ribs are constrained to the inner wall surface of the inner cylinder;

[0010] Its features also include:

[0011] The drive mechanism, connected to the lifting rib drive, is used to drive the lifting rib to move radially along the inner cylinder;

[0012] The pressure detection module is used to detect the pressure of the clothing on the inner drum;

[0013] The controller is electrically connected to the pressure detection module and the drive mechanism, and is configured to control the drive mechanism to perform corresponding actions based on the detection results of the pressure detection module.

[0014] To accelerate the drying rate of clothes and reduce the formation of wrinkles, the controller is also electrically connected to a temperature detection module, which is used to detect the temperature value in the return air duct of the inner drum.

[0015] To facilitate the installation of the pressure detection module, the inner cylinder is connected to a front frame, the pressure detection module is fixed on the front frame, and the pressure detection module is located below the inner cylinder and in contact with the inner cylinder.

[0016] To enable the installation of the temperature detection module, the temperature detection module is fixed to the front frame and extends at least partially into the return air duct of the inner cylinder.

[0017] There are many types of drive mechanisms. Preferably, the drive mechanism includes an electric push rod, and the power output shaft of the electric push rod is connected to the lifting rib.

[0018] In order to achieve stable movement of the lifting rib, the inner wall of the inner cylinder is provided with a boss that protrudes from the outside to the inside, and the wall of the boss is provided with a limiting groove that extends radially along the inner cylinder. The lifting rib is provided with a guide rib that can cooperate with the limiting groove.

[0019] Preferably, the electric push rod is disposed on the boss, the power output shaft of the electric push rod extends radially along the inner cylinder, and the power output shaft of the electric push rod abuts against the lifting rib.

[0020] Furthermore, the electric push rod is located in the center of the boss, and there are two limiting grooves on the boss, respectively located on both sides of the electric push rod of the boss.

[0021] Preferably, there are multiple lifting ribs, which are arranged at intervals along the inner wall surface of the inner cylinder.

[0022] Preferably, the clothes drying equipment is a dryer or a washer-dryer combo.

[0023] Compared with existing technologies, the advantages of this invention are as follows: At the initial stage of drying, the clothes have a high moisture content and are heavy, resulting in significant pressure on the inner drum as they fall, and causing more severe wear and tear on the clothes. Therefore, a pressure detection module detects the pressure of the clothes on the inner drum, allowing the controller to adjust the drive mechanism accordingly based on the detection results. This causes the drive mechanism to move the lifting ribs radially along the inner drum. Thus, this clothes drying equipment reduces the height of the lifting ribs in the early stages of drying, preventing the clothes from falling at the highest point of the inner drum, thereby significantly reducing drum vibration, drying noise, and wear and tear on the clothes.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-6 The image shows the preferred embodiment of the clothes drying equipment in this example. The clothes drying equipment in this example is a dryer or a washer-dryer combo.

[0032] The clothes drying device in this embodiment includes an inner drum 1 and lifting ribs 2 constrained on the inner wall surface of the inner drum 1. The inner drum 1 is rotatably constrained within the housing of the clothes drying device; its structure is prior art and will not be described in detail here. There are multiple lifting ribs 2, arranged circumferentially along the inner wall surface of the inner drum 1. Figure 4 As shown, there are 3 lifting ribs 2 in this embodiment.

[0033] The clothes drying equipment in this embodiment also includes a drive mechanism 3, a pressure detection module 4, a temperature detection module 5, and a controller. The drive mechanism 3 is driven and connected to the lifting rib 2, and is used to drive the lifting rib 2 to move radially along the inner drum 1. The pressure detection module 4 is used to detect the pressure of the clothes on the inner drum 1. The temperature detection module 5 is used to detect the temperature value in the return air duct 10 of the inner drum 1. The controller is electrically connected to the pressure detection module 4, the temperature detection module 5, and the drive mechanism 3. The controller is configured to control the drive mechanism 3 to perform corresponding actions according to the detection results of the pressure detection module 4. In addition, the controller can also control the drive mechanism 3 to perform corresponding actions according to the detection results of the temperature detection module 5.

[0034] like Figure 1 As shown, the inner cylinder 1 is connected to the front frame 6, and the pressure detection module 4 is fixed on the front frame 6. The pressure detection module 4 is located below the inner cylinder 1 and in contact with the inner cylinder 1. Figure 2 As shown, the temperature detection module 5 is fixed to the front frame 6 and extends at least partially into the return air duct 10 of the inner cylinder 1. In this embodiment, the pressure detection module 4 is a pressure sensor, and the temperature detection module 5 is a temperature sensor.

[0035] like Figure 4 and Figure 6 As shown, the inner wall of the inner cylinder 1 has a boss 7 protruding from the outside to the inside, and the lifting rib 2 is sleeved on the boss 7. The wall of the boss 7 has a limiting groove 71 extending radially along the inner cylinder 1, and the lifting rib 2 has a guide rib 21 that can cooperate with the limiting groove 71; Figure 4 and Figure 5 As shown, the drive mechanism 3 in this embodiment includes an electric push rod 31, and the power output shaft of the electric push rod 31 is connected to the lifting rib 2. Figure 4 As shown, in this embodiment, the electric push rod 31 is mounted on the boss 7. The power output shaft of the electric push rod 31 extends radially along the inner cylinder 1, and the power output shaft of the electric push rod 31 abuts against the lifting rib 2. Furthermore, the electric push rod 31 is located in the center of the boss 7, and there are two limiting grooves 71 on the boss 7, respectively located on both sides of the electric push rod 31 on the boss 7.

[0036] The working process of the clothes drying equipment in this embodiment is as follows:

[0037] In the initial stage of clothes drying, if the height of the lifting ribs is too high, the clothes will be carried to the highest point of the inner drum during rotation and then fall under gravity. At this time, the clothes have a high moisture content and are heavy, resulting in greater pressure on the inner drum when falling and more severe wear and tear on the clothes themselves. Therefore, in the early stage of drying, the height of the lifting ribs needs to be reduced to prevent the clothes from falling to the highest point inside the drum. Specifically, the control is as follows: the pressure detection module 4 detects the pressure P1 exerted on the inner drum by the clothes falling after rotation, and compares P1 with a preset threshold P0; if P1≤P0, the stroke of the electric push rod remains unchanged; if P1>P0, the stroke of the electric push rod is controlled to be L0-△L, where L0 is the initial stroke of the electric push rod (in this embodiment, L0 is half of the total stroke of the electric push rod), and △L is the retraction stroke of the electric push rod.

[0038] During the later stages of drying clothes, the temperature inside the inner drum rises sharply. At this point, the moisture content of the clothes has been greatly reduced. Ideally, the clothes should be spread out as much as possible in the inner drum to speed up the drying process and reduce wrinkles. Therefore, the lifting ribs need to be high enough to lift the clothes to the highest point inside the drum before they fall. The specific control is as follows: the temperature value inside the return air duct 10 of the inner drum 1 is detected by the temperature detection module, and the temperature growth rate T1 is recorded at regular intervals. T1 is compared with the preset threshold T0. If T1 ≥ T0, the stroke of the electric push rod is controlled to the maximum value; if T1 < T0, the push rod stroke remains unchanged.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
