Description

Technical Field

[0001] The utility model relates to the technical field of washing machine parts, and particularly relates to a switch structure for a powder box of a drum washing machine. Background Art

[0002] Drum washing machines have been developed for many years. Due to their convenient and efficient washing methods, their application rate is getting higher and higher. However, putting washing powder and washing liquid into the powder box of the drum washing machine, as a necessary step in user use, needs to be manually opened and closed, which brings some inconvenience to users.

[0003] There are also some improvements made in this regard on the market. For example, the spring-loaded powder box structure can reduce the energy consumed by the user for the action of opening the powder box, but it only reduces the action and the closing action is more laborious due to the spring. Therefore, there is an urgent need for a way to liberate both hands and automatically open and close the powder box to improve the experience of the drum washing machine. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the above background art, and to propose a switch structure for a powder box of a drum washing machine.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] A switch structure for a powder box of a drum washing machine includes a spring-loaded water inlet box and a spring-loaded powder box. The spring-loaded powder box is arranged in the spring-loaded water inlet box, and the spring-loaded powder box can pop out from the spring-loaded water inlet box. The spring-loaded water inlet box is provided with a driving member at the tail end. The tail end of the spring-loaded powder box is connected with a pulling rope, and the other end of the pulling rope is tied to the output end of the driving member. The driving member can pull the spring-loaded powder box into the spring-loaded water inlet box through the pulling rope.

[0007] As a further scheme of the utility model: the driving member is a stepping motor.

[0008] As a further scheme of the utility model: the pulling rope is wound around the output end of the stepping motor.

[0009] As a further scheme of the utility model: the switch structure further includes a control board, the control board is electrically connected with the driving member, and the control board is used to control the driving member.

[0010] As a further scheme of the utility model: the switch structure further includes a voice module, and the voice module is electrically connected with the control board.

[0011] As a further solution of the present utility model: A spring is directly provided between the pop-up powder box and the pop-up water inlet box.

[0012] The beneficial effects of the present utility model: By changing the opening and closing method of the powder box of the existing drum washing machine and using a stepper motor device for transformation, a stepper motor is installed at the water inlet box, and a stepper motor with a pull rope is used to replace the manual part in the switch of the pop-up powder box. Since the stepper motor has characteristics such as a controllable rotation angle, forward and reverse rotation, and slow and uniform rotation, it can provide a slow and uniform opening and closing action for the powder box. Moreover, the stepper motor is controlled by a program and combined with a voice module, and the opening and closing action of the door is input through a password, so as to realize the control of the opening and closing action of the powder box without manual operation. Description of the Drawings

[0013] The present utility model will be further described below with reference to the accompanying drawings.

[0014] Figure 1 is a schematic structural diagram of the present utility model.

[0015] In the figure: 1. Driving member; 2. Pull rope; 3. Pop-up water inlet box; 4. Pop-up powder box; 5. Control board; 6. Voice module. Detailed Embodiment

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figure 1 As shown, the present utility model is a switch structure for a powder box of a drum washing machine, including a pop-up water inlet box 3 and a pop-up powder box 4. The pop-up powder box 4 is arranged in the pop-up water inlet box 3. A spring is directly provided between the pop-up powder box 4 and the pop-up water inlet box 3. The pop-up powder box 4 can pop out from the pop-up water inlet box 3. The driving member 1 is installed at the tail end of the pop-up water inlet box 3. The tail end of the pop-up powder box 4 is connected with a pull rope 2. The other end of the pull rope 2 is tied to the output end of the driving member 1. The driving member 1 can pull the pop-up powder box 4 to move into the pop-up water inlet box 3 through the pull rope 2. The driving member 1 is a stepper motor, and the pull rope 2 is wound around the output end of the stepper motor.

[0018] In another embodiment, the switch structure further includes a control board 5, which is electrically connected to the driving member 1 and is used to control the driving member 1.

[0019] In another embodiment, the switch structure further includes a voice module 6, which is electrically connected to the control board 5.

[0020] The stepping motor is fixed on the pop-up water inlet box 3. The pop-up powder box 4 is placed into the pop-up water inlet box 3. The pull rope 2 passes through the pop-up water inlet box 3 to connect the stepping motor and the pop-up powder box 4 together. The control board 5 and the voice module 6 are fixed at any position of the washing machine.

[0021] When a user uses the drum washing machine and gives an instruction (such as opening the powder box), the voice module 6 receives and processes it into an electrical signal, and then transmits the electrical signal to the control board 5. The control board 5 processes and converts it into a working signal for the stepping motor. After receiving the signal, the stepping motor cooperates with the spring device of the pop-up powder box 4 and the water inlet box to slowly open the powder box by simulating the way of applying force to the powder box by hand through the pull rope 2. When it is necessary to close the powder box, the user can give another instruction (such as closing the powder box). Similarly, after the stepping motor receives the closing signal, the pop-up powder box 4 is slowly and evenly closed through the pull rope 2. Thus, the full-automatic switching action of the powder box of the drum washing machine is realized.

[0022] The above has described in detail one embodiment of the present invention, but the above content is only a preferred embodiment of the present invention and cannot be considered as limiting the implementation scope of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the claims of the present invention.
