1. Field of the Invention
The present invention relates to a laundry device, more particularly, to a laundry device which has a coating guide of an improved structure to prevent misassembly between a control panel and a coating guide provided in a control assembly controlling an operation of a laundry machine.
2. Discussion of the Related Art
In general, a laundry device stands for a washer which performs washing and spinning, a dryer which performs drying and a washer combined with a drying function which performs washing and drying simultaneously.
Among them, the washer is classified into a drum type washer and a pulsator type washer.
The dryer is an electric home appliance which generates and supplies hot air to the washed laundry to dry the laundry. The dryer may be usable when the laundry is not naturally dried well such as in a rainy season. Recently, the dryer has been increasingly popular to busy modern people.
Referring to FIG. 1, a conventional dryer will be described.
The conventional dryer includes a top plate 1, a cabinet 2, a front panel 4 and a control assembly 3.
The top plate 1 defines an upper portion of the dryer.
The cabinet 2 defines a side and rear surface of the dryer to protect a drum and various parts installed within the cabinet 2.
The front panel 4 defines a front surface of the dryer and an opening (not shown) is formed in a center of the front panel 4 to introduce the laundry there through.
Also, a door 5 is hingedly coupled to the opening formed a side of the front panel 4 to selectively open/close the opening.
The control assembly 3 has various operation buttons for a user to control the operation of the dryer and is provided on an upper portion of the front panel 4.
Here, referring to FIG. 2, the control assembly 3 will be described in detail.
The control assembly 3 includes a control panel 31, a circuit substrate 32 and a coating guide 33.
The control panel 31 defines an exterior of the control assembly 3 so that the coating guide 33 having the circuit substrate 32 mounted thereon may be connected in rear of the control panel 31.
At that time, an opening 31 a is formed on the control panel 31 to expose outside a button provided on the circuit substrate 32 and a transparent window 31 b is provided on the control panel 31 to make a user recognize a display of a LCD and emitting light of a LED lamp provided on the circuit substrate 32.
Circuit parts are mounted on the circuit substrate 32 to control the operation of the dryer and electrically connected to each other based on each function, as shown in FIG. 2.
The coating guide 33 is provided in plural to hold the plural circuit substrates 32 separately and closes a rear portion of the control panel 31.
Here, the number of housing parts 33 a provided on the coating guide 33 is the same as that of the circuit substrates 32.
However, the conventional dryer has following problems.
Since the housing parts 33 a of the coating guide 33 are separable, work effort may increase only to increase the production cost of housing parts 33 a.
To solve the problem as shown in FIG. 3, one coating guide formed as one body and another problem may arise.
The coating guide 43 formed as one body is coupled to a control panel 41 having a gently curved shape, circuit parts of a circuit substrate 42 mounted within the coating guide 43 might not be corresponding to an opening 41 a and a transparent window 41 b formed on a control panel 41.
That is, as there might be aperture between the coating guide 43 formed in a straight lined shape and the control panel 41 formed in a gently curved shape, a button, an LCD and an LED mounted on the circuit substrate 42 may not be corresponding to the opening 41 a and the transparent window 41 b provided on the control panel 41. Thereby, there might be misassembly or light leakage.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
Referring to FIGS. 4 and 5, a control assembly of a laundry device according to an embodiment of the present invention will be described.
As shown in FIG. 4, a control assembly 300 includes a control panel 310, a circuit substrate 320 and a coating guide 330.
The control panel 310 defines an exterior of the control assembly 300 and protects various parts installed within the control panel 310.
The exterior of control panel 310 may be straight. Recently, since the exterior of the laundry device may be entirely round shaped to enhance external beauty, the control panel 310 also may be round forwardly to a center thereof.
The control panel 310 is installed on a front panel 4 (see FIG. 1) of the laundry device.
A transparent window 311 is formed on the control panel 310 and a plurality of buttons 312 are formed on the transparent window 311 for a user to operate the laundry device by using the same.
A fastening boss 313 is formed on an edge within the control panel 310 and a screw hole is formed on the fastening boss 313 for the coating guide 330 to be fastened thereto.
Various circuit parts are mounted on the circuit substrate 320 to control the operation of the laundry device.
Here, at least two circuit substrates 320 may be configured to categorize the circuit parts in accordance with their functions.
As shown in FIG. 4, two circuit substrates are presented in this specification for convenience sake.
Also, the coating guide 330 holds each circuit substrate 320 to guide antirust liquid applied only on a predetermined area of the circuit substrate 320.
Here, the coating guide 330 includes housing parts 331 that hold the circuit substrates 320 respectively and a connection part 332 that connects the housing parts 331 as one body.
The housing part 331 has a groove to hold the circuit substrate 320 and may be formed in a square shape substantially similar to the shape of the circuit substrate 320.
The connection part 332 is flexible and connects the housing parts 331 each other as one body and gently curves the exterior of the coating guide 330 along an exterior curvature of the control panel 310.
Here, the thickness (t) of the connection part 332 is relatively smaller than the width (T) of a circumferential surface of the housing part 331.
Here, the circumferential surface means a circumference that defines an external circumference of the housing part 331.
The connection part 332 connects a surface of a housing part 331 and a surface of the other housing part 331 each other, which face each other.
The connection part 332 connects the two surfaces of the housing parts 331 and is formed as one body with an entire portion of the two surfaces from an upper end to a lower end.
By the way, a fastening part 333 is formed on the coating guide 330 and has a fastening hole corresponding to the fastening boss 313, such that the coating guide 330 is fastened to the control panel 310.
The fastening structure of the control assembly provided in the dryer according to the above configuration will be described.
First, a cable is electrically connected between the two circuit substrates 320.
Next, the circuit substrates 320 are insertedly mounted in the housing parts 331, respectively.
Hence, antirust liquid is applied on the circuit substrate 320 exposed outside of the coating guide 330 to prevent the various circuit parts mounted on the circuit substrate 320 from being wet, considering a characteristic that the laundry device is exposed to water.
Here, antirust liquid is prevented from leaking out of circuit substrate 320 by the coating guide 330.
Thus, the fastening part 333 of the coating guide 330 having the circuit substrate 320 mounted on is corresponding to the fastening boss 313 of the control panel 310.
At this time, the connection part 332 of the coating guide 330 is gently curved along the external curvature of control panel 310 so that the fastening hole of the fastening part 333 is corresponding to the screw hold of the fastening boss 313.
Hence, a screw is fastened to the screw hole though the fastening hole to complete the assembly of the control assembly 300.
The control assembly 300 is installed on an upper portion of a front panel provided in the dryer.
As mentioned before, according to the embodiment of the present invention, the flexible connection part 333 of the coating guide 330 connects the two surfaces of the housing parts 331 from upper ends to lower ends, which face each other, and the thickness of the connection part 331 is smaller than the width of the circumferential surface configured in the housing part 331.
Alternatively, according to another embodiment of the present invent, a connection part connects some portion of two surfaces of housing parts provided in a coating guide.
As shown in FIG. 6, the control assembly according to another embodiment of the present invention has the same configurations as the control assembly according to the above embodiment but the connection part of another embodiment is different from that of the embodiment.
A coating guide 400 according to another embodiment of the present invention includes a housing part 410 that holds each circuit substrate and a connection part 420 that connects the housing parts 410 each other.
At this time, the connection part 420 connects only some portion between two surfaces of the housing parts 410 which face each other, as shown in FIG. 6, not the entire portion between the two surfaces of the housing parts.
Here, a plurality of connection parts 420 may be provided.
Alternatively, as shown in FIG. 7, one connection part 420 not plural connection parts may be provided.
This connection part 420 may have better flexibility. But, since the connection part 420 may be breakable due to its weak strength, it is preferred that the connection part 420 has a predetermined height enough not to be breakable easily.
Therefore, the connection part 420 of the coating guide 400 according to another embodiment of the present invention connects only some portion between the two surfaces of the housing parts 410 which face each other and thereby it has an advantageous effect of reduced production cost.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
