Problems solved by technology

[0002] At present, the switches used on the freezer are mainly rocker button-type and button-type structures. The rocker or the button is in contact with the live parts. After the button and the button are removed, the whole live part will be completely exposed. The gap between the shells is directly connected to the periphery. After the switch is installed on the box through the control panel, when water flows through the switch during the water spraying test, the water will flow along the button or between the button and the switch shell. If water flows into the gap and reaches the live parts, a breakdown phenomenon will occur when doing withstand voltage, making the test unqualified; if water flows into the button or button during use, the button or button will be charged due to the conductivity of the water, and people will touch it. danger of electric shock

Embodiment 1

[0035] refer to figure 1 As shown, a key-type waterproof switch includes a housing 1, three live terminals 2 are arranged at the lower opening of the housing 1, a button 3 is arranged at the upper opening of the housing 1, and hooks 31 are provided on both sides of the button. When the switch is powered off, the hooks 31 on both sides of the button 3 can be hooked on both sides of the housing 1;

[0036] Such as figure 2 As shown, a partition 4 integrally formed with the housing 1 is provided between the button 3 and the charging terminal 2, a through hole 41 is provided on the partition 4, and a through hole 41 passing through the partition 4 is provided between the button 3 and the charging terminal 2 The force transmission sheet 5, the force transmission sheet 5 is made of plastics, and is electrically insulated. Such as Figure 5 As shown, one end of the force transmission plate 5 is a tip 51 , and the other end has two legs 52 . An indicator light 7 is arranged on th...

Embodiment 2

[0045] refer to Figure 7 As shown, a seesaw button type waterproof switch is different from Embodiment 1 in that the force transmission part only adopts the force transmission piece 5, the force transmission spring 6 is omitted, and the tip 51 of the force transmission piece 5 is connected to A seesaw 8 is provided with a button 9 on the upper part of the seesaw 8. The seesaw 8 is an arc-shaped structure with both ends tilted. one end of the connection.

[0046] Specifically, the switch on and off process: a spring 91 and a cylinder 92 are set between the button 9 and the seesaw 8, the spring 91 is set on the upper end of the cylinder 92, and the lower end of the cylinder 92 is pressed against the arc-shaped groove of the seesaw 8, when When one end of the button 9 is pressed, the lower end of the cylinder 92 will slide toward the end of the seesaw 8 connected to the force transmission piece 5, and the end of the seesaw 8 connected to the force transmission piece 5 is presse...

Abstract

The invention provides a waterproof switch and a refrigerator. The waterproof switch includes a casing. Electrified parts are arranged at an opening at the lower part in the casing. A key or a warping plate is arranged at an opening at the upper part in the casing. A partition wall which is in seal connection with the periphery in the casing is arranged between the key or the warping plate and the electrified parts. Through holes are arranged in the partition wall. A power transmission part which passes through the through holes in the partition wall is arranged between the key or the warping plate and the electrified parts. The invention also provides a refrigerator which adopts the waterproof switch. The waterproof switch prevents direct contact of the button or the key and the electrified parts and encloses the electrified parts in a relatively airtight space so that water does not flow to the electrified parts via the button or the key when flowing through the switch and thus the waterproof performance of the switch is improved significantly.

Description

technical field [0001] The invention belongs to the technical field of electric switches, and in particular relates to a waterproof switch and a refrigerator using the waterproof switch. Background technique [0002] At present, the switches used on the freezer are mainly rocker button-type and button-type structures. The rocker or the button is in contact with the live parts. After the button and the button are removed, the whole live part will be completely exposed. The gap between the shells is directly connected to the periphery. After the switch is installed on the box through the control panel, when water flows through the switch during the water spraying test, the water will flow along the button or between the button and the switch shell. If water flows into the gap and reaches the live parts, a breakdown phenomenon will occur when doing withstand voltage, making the test unqualified; if water flows into the button or button during use, the button or button will be c...
