Abstract
The utility model provides a safety washing machine, which comprises a box body and a Y capacitor arranged on a control panel. The Y capacitor is connected with one end of a ground wire, and the other end of the ground wire is connected with the box body. The box body is fixedly provided with a metal strip. The bottom end of the metal strip is connected with a bottom pin at the bottom of the box body. After the connection of the conductive metal strip with the box body, the conductive metal strip and the box body are grounded. Meanwhile, a rubber pad at the bottom of the box body is connected with the ground through the conductive metal strip served as a conductor. In this way, the current flowing through the box body after being electrified due to the leaky ground wire is guided to flow into the ground through the conductive metal strip and the rubber pad. Therefore, users are free from potential safety hazards caused by electric shock.
Description
Technical field
The utility model relates to the washing machine technical field, is specifically related to a kind of ground wire grounded safe washing machine of washing machine.
Background technology
The washing machine product of China is the Electro Magnetic Compatibility that reaches national relevant regulations, is provided with the filter circuit of Y electric capacity in the washing machine control board.Wherein Y electric capacity is a kind of of safety electric capacity, and safety electric capacity can not cause electric shock after capacitor lost efficacy, do not jeopardize personal safety.Safety electric capacity comprises X electric capacity and Y electric capacity, and X electric capacity is the inhibition differential mode interference electric capacity that is connected across between power line live wire L and the zero line N; Y electric capacity is the inhibition common mode disturbances electric capacity that is connected across respectively between live wire L and ground wire E and zero line N and the ground wire E, generally is paired appearance.
Y electric capacity on the washing machine control board joins with ground wire, ground wire then directly by screw on the outer case of washing machine, the washing machine box body by its footing with contact, owing to be that the insulation non-conductor contacts between footing and the earth, if have electric charge on the washing machine box body then can't discharge, therefore can cause human body contact outer case to have electric shock may.
In the use, if washing machine when work connect is three-phase socket, and ground wire grounded good, then the outer case of human body touch washing machine is can be not feeling; If but ground wire grounded when bad, then have electric charge on the washing machine box body, when human body contact outer case, may have the numb sensation of getting an electric shock, there is certain potential safety hazard.Though the capacity of Y electric capacity meets national safety standard, this problem is still brought very bad experience and security risk to the user.
The utility model content
In order to overcome deficiency of the prior art, the invention provides a kind of safe washing machine, can effectively solve because of the ground wire grounded bad problem that causes electric leakage to make the human electric shock, guaranteed personal safety.
In order to reach above-mentioned effect, the utility model provides a kind of safe washing machine, comprises the Y electric capacity on casing and the control board, and described Y electric capacity is connected with ground wire, and the other end of ground wire is connected with described casing; Be installed with bonding jumper on the described casing, the bottom of described bonding jumper is connected with the footing of being located at bottom half.
Described bonding jumper is steel bar, copper bar or the alloy bar of conduction.
Described footing is coated with rubber blanket.
An end of conductiving metal strip is connected with the casing of washing machine in the utility model, the other end joins by the rubber blanket and the ground of footing, even the casing of washing machine is communicated with ground by conductiving metal strip, if because of the ground wire loose contact causes electric leakage, then the electric current on the casing will import the earth by the conductiving metal strip that links to each other with casing.This is because the resistance of human body is far longer than the resistance of the earthing device of conductiving metal strip and rubber blanket composition, in case ground wire electric leakage, electric current on the casing can not pass through from human body, directly import ground from the little earthing device of resistance, thereby solved the staff engagement washer casing numb hand problem of can getting an electric shock, guaranteed personal safety.Improve the security feature of washing machine simultaneously and promoted user's experience.
After will guaranteeing conductiving metal strip and casing links to each other, the utility model contacts the earth, and make the rubber blanket of casing of washing machine footing realize that with the earth conductor is connected simultaneously, thereby make ground wire import the earth from conductiving metal strip, rubber blanket, avoid bringing potential safety hazards such as electric shock to the person because of electric leakage makes the charged electric current of casing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Among the figure: 1-steel bar, 2-rubber blanket, 3-casing, 4-ground wire, 5-Y electric capacity.
Embodiment
As shown in Figure 1, a kind of safe washing machine comprises the Y electric capacity 5 on casing 3 and the control board, and described Y electric capacity 5 is connected with ground wire 4, and the other end of ground wire 4 is connected with described casing 3; Be installed with steel bar 1 on the described casing 3, the bottom of described steel bar 1 is connected with the footing of being located at casing 3 bottoms, and footing is coated with rubber blanket 2.
Above-mentioned steel bar can also be copper bar or alloy bar.
Wherein an end of steel bar is connected with the casing of washing machine, and the other end joins by the rubber blanket and the ground of footing, thereby the casing of washing machine is communicated with ground by steel bar.If leak electricity because of the ground wire loose contact, then the electric current on the casing will import the earth by steel bar.And can not pass through from the bigger human body of resistance ratio, solved the staff engagement washer casing numb hand problem of can getting an electric shock, guaranteed personal safety.Improve the security feature of washing machine simultaneously and promoted user's experience.
Above embodiment is not limited only to protection range of the present utility model, all make amendment based on basic thought of the present utility model or change all belong to protection range of the present utility model.
