ると必ずしも水平状態が確保されているとは限らない。Problems to be Solved by the Invention However, in the conventional washing machine as described above, the safety switch 30 simply has an ON-OFF operating function, and the safety switch 31 and the outer periphery of the water tray 6 are connected to each other. This position is set with the main body 1 kept in a horizontal state. However, when looking at the actual installation location of the main body 1 at home, a horizontal state is not necessarily ensured.

度の差を発生させていた。For example, when the main body 1 is not installed in a horizontal position, as shown in FIG. , the outer periphery of the water receiver 6 becomes close to the safety switch 30, the safety switch, and the 7-chile lever 31, and the safety switch 3o is immediately turned off and turned OFF at the same time as operation, making dewatering impossible. On the other hand, when tilting backwards, the situation is the opposite of the above, and even if the distance between the outer periphery of the water receiver 6 and the safety switch 31 is too far, and the starting shaking during dewatering is large, the safety switch 30 At this time, there was a problem in which the water receiver 6 and the main body 1 hit each other violently. During so-called tilting, the distances A and B between the main body 1 and the outer periphery of the water pan 6 do not satisfy A=B, and depending on the tilting condition of the main body 1, a difference between A and B occurs, resulting in a difference in the sensitivity of the safety switch 30. was occurring.

A horizontality detection means for detecting the inclination is provided in the safety switch, and a control means is provided for controlling the operating sensitivity of the safety switch means based on a signal from the detection means. This embodiment will be described below based on the accompanying drawings. Components that are the same as those in the conventional example are designated by the same reference numerals, and description thereof will be omitted.

ａ、３４ｂ、３４ｃ。34c, 34d, and 34e, and the bottom outer periphery of the case 32 forms an angle θ1. A substantially arcuate surface having an inclination of θ2 is provided. When the case 32 is in a horizontal state, the conductive steel ball 33 provided inside the case 32 is inserted into the groove 34 between the pair of electrodes 34a provided on the horizontal surface a.
The droplet bulb 33 electrically connects the electrodes 348 between the electrodes 348,
The current flow due to this electrical connection is used to determine whether the object is in a horizontal state. In other words, when the main body 1 is tilted forward to the full angle θ1, the surface at the angle θ1 changes to a horizontal surface, the steel ball 33 rolls upward and moves between the electrodes 34b, and the main body 1 is tilted forward at the angle θ1. The tilting of θ1 is determined by the current flowing between the electrodes 34b. Furthermore, main body 1
When the angle becomes approximately 02, the steel ball 33 moves to the plane C and detects the inclination angle θ2 in the same manner as described above. 36 is each electrode 34

向に移動するよう１（シている。Next, in FIG. 2, 38 is the horizontality detection sensor 32.
This is a safety switch sensor provided at the top of the main body 1 corresponding to A. A cylindrical iron core 4o is fixed above a fulcrum 39a of a substantially Z-shaped safety switch lever 39 that is provided hanging above the safety switch sensor 38.
A substantially cylindrical iron core 42 containing a coil 41 that surrounds the outer peripheral surface of the iron core 4o is disposed on the outer periphery of the iron core 4o. The outer periphery of the water receiver 6 is the safety switch lever 3.

る。FIG. 4 is a graph showing the relationship between the oscillation frequency of the coil 41 and the amount of movement of the iron core 40. When the iron core 40 is normally housed in the coil 41, the amount of movement L1 is determined when the oscillation frequency f is a constant value f1. If the iron core 40 changes to a certain extent, an oscillation frequency of 12 is used to issue a safety order, that is, an operation command to turn off the power to the motor 10. Here, this reference determination sequence is obtained by the horizontality detection sensor 32A. In other words, there is a surface aK$A sphere 33, and when it is determined that the main body 1 is in a horizontal position, Ll and fl in FIG.
It corresponds to the relationship of Next, when the steel ball 33 moves to the facing position, that is, when the horizontality detection sensor 32A determines that the main body 1 is tilted forward at an angle θ1, the position of the safety knob 39 and the outer periphery of the water receiver 9 is determined. is already approaching in the stationary state before operation, and the dimension t shown in FIG. 6 is small and the safety switch tends to operate easily. Therefore, as shown in FIG. and set
The motor 10 is stopped at a related frequency f3 when the amount of movement of the main body 1 becomes larger than the standard when the main body 1 is horizontal. Furthermore, when the angle is θ2, L4
and f4, and all these relationships are input into the microcomputer (not shown) of the control device 4a, and the safety switch sensor 38 is automatically operated in response to the degree of inclination of the main body 1. I try to control the sensitivity.

As a result, even if the horizontality of the main unit is slightly inclined, it will not affect the start-up characteristics when starting the spin-drying operation, and the transition from washing to spin-drying will not occur due to excessive turning off of the safety switch. This also eliminates complaints that the safety switch does not work during dehydration, and the main unit moves due to collision between the main unit and the driving part such as the water receiver without turning off. There will be no more trouble.
