Abstract
Description
Technical field:
[0001] The invention relates to a door lock structure of a clothes dryer, belonging to the technical field of household appliances. Background technology:
[0002] In order to prevent the door of a dryer from opening automatically during operation, a door lock structure is usually required. The door lock structure generally includes a lock body arranged on the main body of the appliance and a door hook arranged on the door body. The lock body and the door hook cooperate with each other to fasten the door body to the box body, so that the door will not open automatically during normal operation, causing safety hazards and affecting normal operation.
[0003] In the prior art, the structure of the door lock and the electric switch are separate, and the structure is relatively complicated.
[0004] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention:
[0005] The present invention aims to solve the above problems in the prior art and provides a door lock structure for a clothes dryer, which can realize the opening and closing of the door of the clothes dryer and can sense whether the door is open or closed.
[0006] The technical solutions adopted in the present invention include: a door lock structure of a dryer, comprising a front door panel and a door assembly installed on the front door panel, a door lock assembly installed on the back of the front door panel, the door assembly installed on the front of the front door panel, a door hook installed on the right part of the back of the door assembly, the left end of the door assembly is pivotally connected to the front door panel, the door lock assembly includes a door lock housing, a switch lever, a micro switch and a lever shaft, a door hook socket is formed on the door lock housing, the switch lever is fixed to the door lock housing through the lever shaft, the door hook is inserted into the door hook socket and is located in front of the switch lever, and the micro switch is located on one side of the door lock housing and is located in front of the switch lever.
[0007] Furthermore, two sets of springs and clamping blocks are installed in the door lock housing, one set of springs and clamping blocks is located in the upper half of the door lock housing, and the other set of springs and clamping blocks is located in the lower half of the door lock housing, and the door hook socket is located between the two sets of springs and clamping blocks.
[0008] Furthermore, the door hook includes a plate portion installed on the back of the door assembly and a hook portion extending from the back of the plate portion.
[0009] Furthermore, when the door is closed, the hook portion is located between the upper and lower sets of springs and the clamping block.
[0010] Furthermore, the rear end of the hook portion is a tapered barb structure.
[0011] Furthermore, the micro switch is provided with contacts.
[0012] The present invention has the following beneficial effects: The door lock structure of the clothes dryer of the present invention is provided with an electric switch on the door lock, so that even if the door is open during normal operation, it can quickly sense the door opening and stop the operation of the clothes dryer. The door latch of the present invention can directly trigger the door lock electric switch signal, resulting in a simple structure and reducing the cost of the door lock. Description of the drawings:

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] The door lock structure of the clothes dryer of the present invention comprises a front door panel 1 and a door assembly 2 mounted on the front door panel 1. A door lock assembly 3 is mounted on the back of the front door panel 1, and the door assembly 2 is mounted on the front of the front door panel. A door hook 2-1 is mounted on the right side of the back of the door assembly 2, and the left end of the door assembly 2 is pivotally connected to the front door panel 1.
[0022] The door lock assembly 3 includes a door lock housing 3-1, a spring 3-2, a clamping block 3-3, a switch lever 3-4, a micro switch 3-5 and a lever shaft 3-6. A door hook socket 3-1-1 is formed on the door lock housing 3-1. Two groups of springs 3-2 and clamping blocks 3-3 are installed in the door lock housing 3-1, one group of springs 3-2 and clamping blocks 3-3 are located in the upper half of the door lock housing 3-1, and the other group of springs 3-2 and clamping blocks 3-3 are located in the lower half of the door lock housing 3-1. The door hook socket 3-1-1 is located between the two groups of springs 3-2 and clamping blocks 3-3, and the springs 3-2 and clamping blocks 3-3 provide clamping force when closing and opening the door.
[0023] The micro switch 3-5 is located on one side of the door lock housing 3-1 and in front of the switch lever 3-4.
[0024] When the door is closed, the door hook 2-1 is inserted into the door hook socket 3-1-1. At this time, the hook 2-1 is located between the upper and lower springs 3-2 and the clamping block 3-3. The switch lever 3-4 is mounted on the door lock housing 3-1 via the lever shaft 3-6 and is located at the rear end of the door lock housing 3-1.
[0025] The door hook 2-1 includes a plate body 2-2 installed on the back of the door assembly 2 and a hook portion 2-3 extending from the back of the plate body 2-2. The rear end of the hook portion 2-3 is a conical hook structure. When the door hook 2-1 is inserted into the door hook socket 3-1-1, the clamping block 3-3 will be stretched open. After the maximum position of the door hook 2-1 (that is, the entire conical hook structure) passes the position of the clamping block 3-3, the clamping block 3-3 will clamp the door hook 2-1 under the action of the spring 3-2, thereby locking the door.
[0026] When closing the door, the door hook 2-1 will hit one side of the switch lever 3-4 after it is in place. The switch lever 3-4 is fixed to the door lock housing 3-1 through the lever shaft 3-6. When the door hook 2-1 hits one side of the switch lever 3-4, the other side of the switch lever 3-4 will rotate and hit the contact 3-5-1 of the micro switch 3-5, then triggering the micro switch 3-5 to close and provide a door closing signal.
[0027] When the door is opened, the door hook 2-1 is pulled out, the top force of the switch lever is released, the micro-switch contact pops open, and the door is sensed to be opened.
[0028] The door lock structure of the clothes dryer of the present invention can realize the opening and closing of the door of the clothes dryer, and senses whether the door is in an open or closed state through a micro switch.
[0029] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
