Abstract
Description
Technical Field
[0001] The utility model relates to the field of switches, in particular to a washing machine switch. Background Art
[0002] A washing machine is a common small household appliance. During operation, in order to ensure safety and normal operation, a variety of switches need to work together. For example, a washing machine door switch can avoid safety hazards caused by opening the lid in the middle of operation, and a drum bumping switch can prevent damage to the washing machine due to drum bumping. The washing machine door switch usually includes a shell for installation on the washing machine body, and a moving contact and a static contact are provided on the shell. When the washing machine door is closed, the moving contact will be driven by the corresponding rocker arm to abut against the static contact, forming a circuit connection. Then the electrical signal is transmitted to the control system of the washing machine to operate normally, otherwise it will stop running. The main difference of the drum bumping switch is that the rocker arm that cooperates with its moving contact is coordinated with the drum bumping. When there is a problem with the placement of clothes in the drum bumping, the rocker arm will swing, allowing the rocker arm to drive the moving contact to frequently open and close the circuit. Then the electrical signal is transmitted to the control system of the washing machine to stop running. At present, the lid opening switch and drum bumping switch of the washing machine are usually set independently, which increases the complexity of the washing machine switch installation structure and increases the switch cost. Utility Model Content
[0003] In view of the deficiencies in the prior art, the present invention provides a washing machine switch that can integrate more functions, help optimize the overall structure and effectively reduce costs.
[0004] To achieve the above-mentioned purpose, the utility model provides a washing machine switch, comprising a shell, in which a first contact and a second contact are arranged, the first contact and the second contact abut each other to form conductivity, and further comprising a first swinging member and a second swinging member which are swingably arranged, one end of the first swinging member extending to form a hook portion for cooperating with the washing machine door, the other end of the first swinging member extending into the shell and provided with a first abutting portion, the first abutting portion can cause the first contact to deform and press tightly against the second contact under the drive of the first swinging member, one end of the second swinging member extends toward the direction of the collision barrel and is provided with a card slot, and a second abutting portion is provided at the other end of the second swinging member, the second abutting portion abuts against the second contact, and the second abutting portion can be pressed against the second contact under the drive of the second swinging member, causing the second contact to deform and swing in a direction away from the first contact.
[0005] The advantages of adopting the above technical solution are: by setting a first swinging member and a second swinging member that cooperate with the first contact piece and the second contact piece respectively, and allowing the first swinging member and the second swinging member to cooperate with the washing machine door and the bumper barrel respectively, the positional relationship between the first swinging member and the second swinging member changes, and the two key functions of washing machine door switch status detection and bumper barrel detection are integrated into the same switch structure, wherein the first swinging member is linked to the washing machine door through a hook to control the contact between the first contact piece and the second contact piece to realize the door switch signal transmission; and the slot of the second swinging member responds to the bumper barrel situation, driving the second abutment part to make the second contact piece swing to change the circuit state, simplifying the overall structure, integrating functions and simplifying the structure, reducing the number of parts, reducing space occupancy, reducing material procurement costs, assembly complexity and assembly hours, reducing manpower and time investment in the production process, and achieving efficient unification of function, structure and cost while improving product reliability.
[0006] The present invention can be further configured as follows: a slider is provided in the shell, one end of the slider elastically abuts against the inner wall of the shell, the first abutting portion abuts and cooperates with the other end of the slider, and the slider is provided with a raised portion for abutting against the first contact piece. The slider can slide laterally under the push of the first abutting portion, and the first contact piece can be pressed against the second contact piece under the push of the raised portion on the slider.
[0007] Through further configuration, one end of the slider is elastically abutted against the inner wall of the shell, so that it can slide laterally under the push of the first abutting part, forming elastic buffering and mechanical conduction. The elastic abutment can not only ensure the stability of the slider's reset, but also accurately transmit the thrust through sliding when under force. The way in which the raised part on the slider abuts against the first contact piece can allow the swinging first abutting part to be converted into deformation force on the first contact piece through the lateral displacement of the slider, which makes the cooperation more stable and improves the contact reliability.
[0008] The present invention can be further configured as follows: a guiding inclined surface is provided on the raised portion, a first arc block is provided below the first contact piece, and the first arc block abuts against the guiding inclined surface.
[0009] Through further configuration, the guiding slope of the raised portion cooperates with the first arc block under the first contact piece to form a smooth sliding contact structure. When the slider moves laterally, the guiding slope converts the horizontal thrust into pressure perpendicular to the first contact piece through the first arc block, thereby realizing force transmission.
[0010] The present invention can be further configured as follows: an arc-shaped recess is provided on the second abutting portion, a second arc block is provided below the second contact piece, and the second arc block is elastically reset to the arc-shaped recess along with the second contact piece.
[0011] Through further configuration, the arc-shaped recess of the second abutting portion cooperates with the second arc block under the second contact piece. When the second swinging member drives the second abutting portion to move, the arc-shaped recess applies controllable pressure to the second contact piece through the second arc block to drive the elastic deformation of the second contact piece. When elastically resetting, the second arc block automatically snaps into the arc-shaped recess to ensure the accuracy of the contact piece returning to its initial position.
[0012] The present invention can be further configured as follows: an ear and a reset spring are provided on the second swinging member, one end of the reset spring abuts against the ear, a slot is provided at a position of the shell opposite to the ear, and the other end of the reset spring is inserted into the slot.
[0013] Through further settings, ears are provided on the second swinging member to cooperate with the reset spring, and a slot is provided on the shell. When the impact barrel triggers the second swinging member to swing, the spring produces elastic deformation to store energy. After the external force disappears, the spring drives the second swinging member to accurately reset through the ears, providing a stable elastic reset mechanism for the impact barrel detection function.
[0014] The present invention may be further configured as follows: the first contact piece includes a first bending portion, and the first abutting portion abuts against an upper portion of the first bending portion.
[0015] Through further configuration, since the motion trajectory of the first abutting portion is a circular motion, the first contact piece is bent to form a first bent portion to cooperate with the first abutting portion, so that the first abutting portion can better push the first contact piece to deform and swing.
[0016] The present invention can be further configured as follows: a third arc block is provided above the second contact piece, and the second abutting portion is bent and extended to the top of the second contact piece and abuts and cooperates with the third arc block.
[0017] Through further configuration, a third arc block is provided above the second contact piece, so that the third arc block is in abutment with the second abutting portion that is bent and extended. When the second swinging member drives the second abutting portion to move, the bending structure applies pressure to the second contact piece through the third arc block, prompting the second contact piece and the first contact piece to separate, thereby realizing the switching of the circuit state and ensuring the controllability of the contact piece deformation.
[0018] The present invention can be further configured as follows: an ear and a reset spring are provided on the second swinging member, one end of the reset spring abuts against the ear, a slot is provided at a position of the shell opposite to the ear, and the other end of the reset spring is inserted into the slot.
[0019] Through further settings, ears are provided on the second swinging member to cooperate with the reset spring, and a slot is provided on the shell. When the impact barrel triggers the second swinging member to swing, the spring produces elastic deformation to store energy. After the external force disappears, the spring drives the second swinging member to accurately reset through the ears, providing a stable elastic reset mechanism for the impact barrel detection function.
[0020] The present invention can be further configured as follows: a sealing sleeve corresponding to the first swinging member is provided on the shell, the sealing sleeve is made of elastic material, one end of the sealing sleeve is engaged with the shell and limited, and a sealing groove is formed on the first swinging member for the other end of the sealing sleeve to be embedded.
[0021] Through further configuration, a sealing sleeve made of elastic material is provided between the shell and the first swinging member. Since the first swinging member is to form a transmission cooperation with the washing machine door, the sealing sleeve provides protection without affecting the movement of the first swinging member, preventing water vapor and impurities from entering the switch through the gap between the first swinging member and the shell, thereby ensuring stable operation of the product.
