The controller part controls the rotation of the inner tub by the rotation of the pulsator controlled by the controller, or the rotation of the inner tub Which is a product that removes various pollutants adhered to clothes, bedding or the like by using the laundry permeation action of the water stream and the emulsifying action of the detergent.

Meanwhile, with the development of Internet technology, the need for a washing machine using the Internet is increasing day by day.

That is, it is possible to expand the functions of the laundry by further downloading various laundry functions necessary for washing through the Internet, and to continuously check the operation of the washing machine, thereby storing the amount of laundry and the type of laundry in the data bears So that it is possible to add a customized function to the washing machine. Therefore, the need for a washing machine using the Internet is increasing day by day.

In order to incorporate the above-described Internet technology into a washing machine, a technique for connecting a washing machine to a so-called PC, which is an intermediate medium between the Internet and a washing machine, is required. In general, a washing machine is a device using water, a problem may arise in that the connector part is short-circuited. Therefore, there is a need for a preferable technique for connecting the washing machine and the intermediate medium.

The present invention has been made based on the above needs, and it is an object of the present invention to improve the structure of a controller assembly of a washing machine so that a washing machine and a computer are mutually connected to diversify functions of a washing machine, The purpose is to extend the life span.

In order to achieve the above object, according to the present invention, there is provided a liquid crystal display device comprising a driver circuit board provided in a small section of a main body and having an apparatus for downloading or uploading external data, And an external connection port detachably connected to an external cable for downloading external data or uploading data to the external device, the external connection port being mounted on the driving circuit board, And an inflow preventing member for blocking the inflow of the coating liquid and the water into the external connection port.

The above description will be made in more detail with reference to the drawings.

FIG. 2 is a sectional view showing the structure of a controller assembly according to the present invention, FIG. 3 (a) is a side view of FIG. 2, and FIG. 3 (b) is a plan view of FIG.

2 to 3B, the controller assembly according to the present invention includes a driving circuit substrate 10 provided in a small portion of a main body (refer to 1 in FIG. 1) and serving as a medium for transmitting a signal, (Not shown) mounted on the driving circuit board for downloading external data or uploading data to the outside, a coating liquid 20 applied to the upper and lower surfaces of the driving circuit substrate to block the inflow of the liquid, And an inflow prevention member 40 for blocking the inflow of the coating liquid and water into the external connection port.

At this time, the external connection port 30 has a hook protrusion 33 formed at a lower end thereof to transmit a concentrated load applied to an external cable (not shown) to the driving circuit board 10, So as to be hooked to the substrate.

The inflow preventing member 40 is formed by insert injection so as to be in close contact with the exterior of the external connection port 30 and a hook protrusion 41 is formed at a lower end thereof, .

The present invention as described above performs the following functions.

The present invention can down-load external infinite data through the external connection port 30 mounted on the driving circuit board 10 or can check the check list checked in the washing machine A connecting structure in which a washing machine and a computer are connected to each other is installed in the washing machine so that the washing machine can be uploaded to the outside.

That is, a connecting structure, which is a structure capable of grasping the type of laundry and the type of laundry, can be transmitted to the outside, is established, and further development of a technology capable of transferring a program necessary for the washing machine from the outside is progressing, A variable type washing machine that provides a variable washing function to allow a consumer to select a required washing function and a customized washing machine that provides a washing function suited to a consumer.

Accordingly, all electronic parts mounted on a washing machine using water must have a waterproof structure.

That is, for the purpose of the present invention, the insert injection preventing means, such as so-called double injection, is formed in the external connection port 30 so as to closely contact the inflow preventing member 40, Thereby blocking the coating liquid 20 and water which have flowed into the external connection port.

For example, the coating liquid 20 is not fixed to the pin hole (see 31 in FIG. 3B) formed in the external connection port 30, and water is prevented from flowing into the gap formed in the periphery of the external connection port.

Accordingly, since the coating liquid 20, which is an obstacle, is not fixed in the pin hole 31 of the external connection port, the external cable can be detachably inserted, and water can be introduced into the peripheral portion of the external connection port 30 There is no possibility that the electric components that are seated in the inside of the apparatus become short-circuited, the malfunction of the apparatus can be prevented beforehand, and the life can be prolonged because there is no possibility of corrosion due to water.

Since the external connection port 30 and the external cable are detachable, the external cable is disconnected from the external connection port during non-use. The external force applied at this time is applied to the external connection port And is transferred to the drive circuit board 10 at the same time as the load, and is converted to a concentrated load.

That is, if only the pin unit 32 protruding to the lower end of the external connection port 30 and the driving circuit board are coupled to each other, the concentrated load affects only the coupling portion between the pin unit and the driving circuit board 10 , The pin portion may be short-circuited or a crack may be generated in the driving circuit substrate.

Therefore, in order to solve this problem, the inflow preventing member 40 may have a separate hook protrusion 31 formed at the lower end of the inflow preventing member when the insert is injected with the external connection port 30, So that the concentrated load is distributed to the hook protrusions.

In order to prevent water from flowing into the connection portion of the external connection port while the external connection port 30 and the external cable are not connected to each other, a cap 50 for blocking the connection portion is further included desirable.

The reason for this is that the external connection port 30 to be used in the present invention is a connector having a so-called pin hole 31 having a female structure. If water flows into the pin hole, 10), electric components are likely to be short-circuited to each other so as to prevent this in advance.

That is, the stopper 50 is detachably mounted on the upper end of the external connection port 30 to block water from flowing into the pin hole 31, which is a connecting part, when the external cable is not connected .

The external connection port 30 may have a male structure in which a pin is not formed but a female structure in which a pin hole 31 is formed, but any person skilled in the art can understand that a plug is required as described above .

At this time, the stopper 50 is preferably made of a rubber material.

The reason for this is that the rubber material is a material having excellent adhesiveness due to its nature. Therefore, when the plug is attached, the rubber material is excellent in adhesion with other members, and the sealing area is relatively increased. In addition, It is because.

It should be understood by those skilled in the art that although the present invention has been described in connection with a washing machine, it is possible to use the washing machine as well as the water washing machine and the water washing machine.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.

As described above, according to the present invention, unlimited data from outside can be downloaded through the external connection port mounted on the driving circuit board, or the washing machine and the computer are connected to each other so that the check list checked in the washing machine can be uploaded to the outside So that the connecting structure is mounted on the washing machine and the waterproof structure is formed.                     

Accordingly, in addition to establishing a connecting structure that can grasp the type of laundry, such as washing machine use information, and transmit it to the outside, development of a technology capable of transferring a program including a washing function necessary for a washing machine from the outside It is possible to further develop the development of a variable type washing machine that provides a variable washing function by which a consumer can select a required washing function and a customized washing machine that provides a washing function suited to a consumer.

In addition, since the inflow of water into the external connection port is blocked, malfunction of the device can be prevented in advance, or the service life of the device can be prolonged.

In addition, since the waterproof structure using the rubber stopper and the coating liquid is used, it is possible to prevent water from flowing into the controller, and to prevent a plurality of electric parts (resistors, transistors, etc.) mounted on the circuit board from being short- .

Accordingly, as described above, since the waterproof structure is completely provided, it is possible to prevent the malfunction of the device as a whole, and the life of the device can be prolonged because the device is not aged by water.

And includes all the effects mentioned in the description of the invention.
