There is no obstacle when the lid is opened and closed by the convex portion 3a.

Next, the signal transmission / reception unit in the case of transmitting / receiving a signal by an infrared signal will be described with reference to FIGS.

8 to 9, the operation side transmitter / receiver 11 mounted on the front cover 6 is, as shown in FIG. 10, arranged inside a transmitter / receiver case 33 made of a material through which an infrared signal can pass, and a substrate 34. And the infrared transmitting element 35 and the infrared receiving element 36 attached to the board 34, and the signal reflecting section 3
It consists of having 7. Since the surface of the signal reflection portion 37 has a fine uneven hemispherical shape, it is possible to irregularly reflect the transmission and reception of infrared rays. still,
The main body side transmitter / receiver 13 mounted on the top cover 3 is the same as the operation side transmitter / receiver 11.

As a result of the above, the signal of the infrared transmitting element 35 is reflected and diffused to the outside and the signal transmitted from the other is received by the infrared receiving element in any state when the lid 5 is opened or closed in FIGS. 8 and 9. Can be reflected to 36.

Next, the hinge portion of the lid will be described with reference to FIGS.

11 to 12, a front lid 6 and a rear lid 7 are shown.
A coil spring 38 is attached to each of a hinge 8 which is connected so as to be bendable, and a hinge 9 which is connected to the top cover 3 so that the rear lid 7 is rotatable. This coil spring 38 is adapted to apply a braking force to the weight of the lid 5, and
From the closed state of the lid 5 of No. 1 to the opened state of the lid 5 of FIG. 12, it is possible to open the lid 5 while controlling a sudden rearward fall due to its own weight. On the contrary, when the lid 5 shown in FIG. 12 is opened and the lid 5 shown in FIG. 11 is closed, the lid 5 can be closed while controlling a sudden downward fall due to its own weight.

As described above, according to the present embodiment, when operating the operating portion 10 arranged on the front lid 6, the front lid 6 faces forward when the lid 5 is open as shown in FIG. Since it is in the upright position, the operation of the operation unit 10 is not hindered. Further, even in the closed state as shown in FIG. 2, since the operation portion 10 is located on the front portion of the upper surface of the main body 1, the operation is not hindered.

Further, since the front part of the laundry entrance / exit 4 of the main body 1 is not hidden by the operation part 10, a wide laundry entrance / exit can be secured without hindering the operation, and the entrance / exit of the laundry is facilitated. .

Further, since the entire upper surface of the front lid 6 can be used as the operation section, the display section and the operation buttons can be made as large as necessary within the area of the entire upper surface of the front lid 6. Therefore, it is possible to form an operation portion that is easier to see and press.

Signal transmission / reception between the operation unit 10 in the front cover 6 and the control unit 17 in the outer box 2 is performed by an infrared signal or a wireless signal, and power is supplied to the operation unit 10. For, the electromagnetic induction technology is used, so wiring for each part is not required. Therefore, since the wiring does not pass through the inside of the lid 5, the possibility of increasing the weight of the lid 5 itself and cutting the wiring at the hinges 8 and 9 of the lid 5 is low.
It is possible to improve the assemblability and to improve the environmental responsiveness such as easy separation and disposal of each component.

Further, since the transmission / reception angle of the infrared transmission element 35 and the infrared reception element 36 is generally 60 degrees, transmission / reception is possible in any state when the lid 5 is opened / closed in FIGS. 8 and 9. In order to do so, it is necessary to mount the infrared transmitting element 35 and the infrared receiving element 36 at an angle at which transmission / reception is possible in each open / closed state of the lid 5. Therefore, two infrared transmitting elements 35 and two infrared receiving elements 36 are required, respectively, and the main body side transmitting / receiving section 13 and the operating side transmitting / receiving section 11 are separate parts, which causes an increase in the number of parts. However, according to the present invention, since the surface of the signal reflection portion 37 of the operation side transmission / reception unit 11 is made into a fine uneven hemispherical shape, infrared transmission / reception can be diffusely reflected. Therefore, the main body side transmitter / receiver 13 and the operation side transmitter / receiver 11 can be used as a common component, and further, even if they are mounted in the same state, signal transmission / reception can be reflected and diffused. It is possible to perform transmission / reception in any state when the lid 5 is opened / closed.

Since the coil spring 38 is adapted to control the own weight of the lid 5, there is no sudden fall when the lid 5 is opened or closed. Therefore, the display of the operation unit 10 arranged on the lid 5, the board, etc. Is less likely to be impacted. Therefore, there is an effect that the display of the operation unit 10 and the substrate are less likely to be damaged.

[Second Embodiment] FIGS. 13 to 14 show a second embodiment of the present invention.

13 to 14, the operation unit 10 is composed of the display unit 18, the operation cover 23, and the operation switch 23a. However, only the display unit 18 is arranged on the front cover 6, and the operation cover 23 and the operation are performed. The switch 23a is arranged in a strip shape on the front portion of the top cover 3 and is exposed when the lid 5 is opened or closed.

The other arrangement is the same as that of the first embodiment.

According to the present embodiment, when the display section 18 arranged on the front lid 6 is made to be a liquid crystal display, a button (not shown) for turning on / off the display is equipped and this button is operated. As a result, when the display is on, the operation status is displayed on the display surface, and when the display is off, the display surface is transparent. As a result, the laundry in the main body 1 can be seen from the display surface when the display is turned off, so that the display unit 18 can be a display unit that also serves as a window for confirming the laundry state. From the above,
Since it is not necessary to dispose both the window and the display section in one area, the space can be effectively utilized, and the display section can be enlarged, and the visibility can be improved accordingly.

Further, the operation cover 23 and the operation switch 23a are arranged on the front portion of the top cover 3 in a belt shape, and since the display portion is not arranged, the range for closing the laundry entrance / exit 4 is narrow. Therefore, although the operation switch and the like are arranged on the top cover 3, it is less likely to interfere with the loading and unloading of the laundry, and the possibility of impairing the handleability is low.

Further, since the operation switches arranged in strips are exposed even when the lid 5 is closed, there is no problem in the operation when the lid 5 is opened or closed. Furthermore, since the display unit 18 is arranged on the front cover 6,
Even when the lid is open, the display is in a standing position and faces the front so that visibility is not impaired.

[Third Embodiment] FIGS. 15 to 17 show an electric washing machine according to a third embodiment of the present invention.

In FIGS. 15 to 16, the operating portion 10 arranged on the front lid 6 has a raised portion protruding upward from the upper surface of the front lid 6 as shown in FIG. The raised portion is inclined forward and a handle for opening and closing the lid is formed on the rear side. Then, the operation board and the like are arranged in this raised portion.

The other arrangement is the same as that of the first embodiment.

According to the present embodiment, since the convex raised portion of the operating portion 10 also serves as the handle for opening and closing the lid 5, the space can be effectively utilized, and the operating portion can be enlarged accordingly. Operability and visibility can be improved.

Further, since the convex raised portion of the operating portion 10 is inclined forward, the operability and the visibility are good.

Further, since the raised portion of the operating portion 10 is formed to be convex above the front lid 6, the thickness of the lid itself can be reduced. As a result, the weight of the lid itself becomes light and the lid can be easily opened and closed.

[0046]

According to the present invention, since the operating portion does not block the opening portion while maintaining the operability, a wide opening portion can be obtained, and clothes can be taken in and out easily. Also, since the wiring does not pass through the lid, there is no increase in the weight of the lid, there is no need to cut the wiring at the lid hinge, and wiring is not required for each part, improving disassembly and assembly, and It is possible to improve environmental responsiveness such as easy separation and disposal.
