Technical Field

[0001] This utility model relates to the field of dryer door lock technology, and in particular to a dryer door lock structure. Background Technology

[0002] Dryers use electric heating to evaporate the moisture in clothes, thus achieving the effect of drying them. They are usually used on rainy or cold days and can effectively prevent clothes from getting moldy or smelly due to prolonged drying. The door lock structure is used to fix the position of the door. If the door is opened during the drying process, the drying will stop immediately.

[0003] Existing dryer door locks mainly consist of two types: strong magnetic adsorption structure and ball-operated door catch structure. Both lack the necessary locking mechanism. Damp clothes gradually become fluffy during the drying process, causing them to expand in size and easily push open the dryer door lock, thus causing the equipment to stop and malfunction.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Existing dryer door locks mainly consist of two types: strong magnetic adsorption structure and ball-operated door catch structure. Both lack a necessary locking mechanism. During the drying process, damp clothes gradually become fluffy and increase in volume, easily pushing open the dryer door lock, causing the equipment to stop and malfunction. To address this technical deficiency in existing technologies, such as... Figures 1-4 As shown, this embodiment provides a dryer door lock structure that can effectively prevent damp clothes from opening the door as they gradually dry and fluff up. The door lock structure includes an outer handle mechanism 1, an inner handle mechanism 2 on the outer handle mechanism 1, and the inner handle mechanism 2 and the outer handle mechanism 1 are slidably connected.

[0023] The outer handle mechanism 1 includes an outer pull plate 101, an elliptical groove 102 is provided on the outer pull plate 101, an installation screw 103 is fixedly installed on the outer pull plate 101, a limiting plate 104 is fixedly installed between the elliptical groove 102 and the installation screw 103, a pushing component 105 is provided on the side of the limiting plate 104 away from the elliptical groove 102, the pushing component 105 includes a spring guide post fixedly installed on the limiting plate 104, a spring body is sleeved on the outside of the spring guide post, two sets of spring guide posts and spring bodies are symmetrically arranged, and a limiting pressure plate 106 is fixedly installed on the outer pull plate 101.

[0024] The inner pull mechanism 2 includes an inner pull plate 201 movably mounted on the outer pull plate 101. The inner pull plate 201 is slidably connected to the limiting pressure plate 106. When the user pulls the inner pull plate 201, the rectangular plate 202 and the locking tongue body 203 will move synchronously. A rectangular cavity 204 is provided on the inner pull plate 201. The limiting plate 104 extends upward through the rectangular cavity 204. The rectangular plate 202 is provided on the inner pull plate 201. The end of the spring body away from the limiting plate 104 abuts against the rectangular plate 202. Initially, the outer pull plate 101 is in the maximum stroke state under the action of the spring body. The locking tongue body 203 is fixedly installed on the rectangular plate 202. When the inner pull plate 201 moves horizontally, the locking tongue body 203 will move out of the locking hole on the drying equipment.

[0025] As can be seen from the above, during installation, the staff will use the installation screws 103 to fix the outer pull plate 101 to the door of the drying equipment. During the drying process, the user will first put the clothes into the dryer and then close the door.

[0026] During the closing process, simply push the door gently to bring the latch body 203 into contact with the drying equipment. At this time, the spring body will be compressed. When the latch body 203 is aligned with the locking hole on the drying equipment, the latch body 203 will immediately extend into the locking hole under the elastic force of the spring body, thereby locking the dryer door.

[0027] After drying, the user will insert their hand through the elliptical groove 102 into the inside of the outer pull plate 101, and then pull the inner pull plate 201 to move the rectangular plate 202 synchronously, thereby moving the latch body 203 out of the locking hole.

[0028] This embodiment, by setting an outer handle mechanism 1 and an inner handle mechanism 2, utilizes the cooperation between the inner pull plate 201 and the pushing component 105 to automatically lock and limit the door during the closing process of the dryer door, which can effectively prevent damp clothes from pushing the door open and causing the equipment to stop as they gradually dry and fluff up. In addition, by setting an outer handle mechanism 1 and an inner handle mechanism 2, and utilizing the cooperation between the limiting pressure plate 106 and the rectangular cavity 204, this embodiment can limit the movement stroke of the inner pull plate 201, preventing the inner pull plate 201 from falling off the outer pull plate 101. The structure is compact and easy to use.
