- In general, the washing machine, performing a washing cycle, a rinsing cycle, a spinning cycle, and the like by rotating a rotating tub and a pulsator with a motor, washes laundry with friction between laundry and washing water and the rotating tub caused by pulsation of the washing water and the laundry introduced into the rotating tub.
- In the washing machines, there are pulsator type, agitator type, and drum type washing machines according to washing methods.
- In general, the drum type washing machines, in which washing is made by friction between a washing drum rotated by driving force of a driving unit transmitted thereto and the laundry in a state where detergent, washing water and the laundry is introduced into the washing drum, gives little damage to the laundry, makes little entangling of the laundry, and can provide a washing effect of pounding, and rubbing the laundry.
-
FIG. 1 illustrates a related art drum type washing machine, including acontroller 3 at an upper portion of a body having an input unit with input keys for user's inputting commands for thecontroller 3 and a display unit for displaying a time period left and the like. - The
controller 3 is provided with a plurality ofbuttons 31, adisplay window 32, anLED window 33, and arotary knob 50. The buttons and theknob 50 are input devices for a user's operating the washing machine. The user handles the buttons and theknob 50 at the time the user selects a washing time period, a washing method, spinning and drying methods in inputting desired washing course, and time period. - The
LED window 33 by flashing and thedisplay window 32 by character or symbol inform various kinds of washing information, such as a washing progress state, a remained time period and the like to the user. - In the meantime, in general, a laundry dryer dries wet drying object (for an example, laundry) automatically, wherein, alike the related art drum type washing machine in
FIG. 1 , a related art laundry dryer has a controller at an upper portion of a body. - Thus, since the related art washing machine or laundry dryer has the controller at the upper portion of the body, the related art washing machine or laundry dryer has inconvenience in use in that access to the controller is not easy in a case the controller is positioned high from a place the user is standing. In the inconvenience, other than the inconvenience of handling the input unit of the controller positioned at a high place, there is also inconvenience of looking up the display unit.
- If the washing machine and the laundry dryer are arranged horizontally, use of the washing machine and the laundry dryer is not inconvenient. If, however, one is stacked on another one, there will be much difficulty in handling the controller of the one arranged on an upper side.
- An object of the present invention is to solve above problems.
- Another object of the present invention is to provide a laundry machine, which has less inconvenience in handling a controller even if the machine is arranged at a high place, particularly, on another laundry machine, including, of course, a case where the machine is positioned at floor level.
- Along with this, a further object of the present invention lies on achieving above object even with one input unit by making at least the input unit of the controller can be detachably mounted to an upper portion or a lower portion of a body, selectively.
- A still further object of the present invention lies on enabling electrical connection to a main control unit done with a simple work in a case an input unit is mounted with a position thereof changed.
- To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a laundry machine includes a body having a first connector and a second connector each for electrical connection to at least a component inside the body, and a changeable controlling unit detachably mounted to a position of the body corresponding to the first or second connector selectively, and electrically connected to the first connector or the second connector, the changeable controlling unit having at least an input unit or a display unit.
- The laundry machine can be a dryer, a washing machine, a washing and drying machine, or so on. The laundry machine is an apparatus for handling laundry, and includes all kinds of apparatus related to laundry; even a dewatering machine (or a spin drying machine) is not excluded.
- In the present invention, besides the first connector and the second connector, there can be other connectors, and the present invention does not exclude other connectors. That is, in the present invention, at least to connectors can be provided to the cabinet, so that a position of the changeable controller can be changed between to or more than two places.
- If a washing machine which is one of the laundry machines is taken as an example, in a body of the washing machine, there are a drum for holding laundry, a motor for rotating the drum, a water supply valve for controlling washing water supply, and a drain pump for draining the washing water. The controller has a main control unit for controlling the motor, the water supply valve, the drain pimp, or so on according to a preset operation course, an input unit for receiving selection of the operation course, or the like from the user, and a display unit for displaying information on operation of the laundry machine to the user.
- In general, the main control unit in the laundry machine is provided with a microcomputer for controlling various components of the laundry machine according to the operation course, or the like of the laundry machine. For an example, in the washing machine, the main control unit controls operation of the motor, the water supply valve, the drain valve, and the like according to a preset operation course.
- In the related art, at least the input unit and the display unit are fixedly secured to an upper portion of the laundry machine. The mounting place of the units can not be changed on the machine.
- In the present invention, a changeable controlling unit is mounted to an upper portion or a lower portion of the laundry machine selectively, having at least an input unit or a display unit of a controller.
- Therefore, if the laundry machine is mounted to a relatively high place, a position of the input unit or the display unit may be changed from the upper portion to the lower portion of the laundry machine, for user's easy access thereto.
- The changeable controlling unit may include the main control unit, the input unit, and the display unit. Or, the main control unit may be fixedly secured to a fixed position in the laundry machine, and the changeable controlling unit may include the input unit or the display unit.
- Provided to the cabinet of the body of the laundry machine, there are at least a first mounting structure and a second mounting structure as mounting structures for mounting the changeable controlling unit to the body. The first connector and the second connector are arranged at positions corresponding to the mounting structures at the cabinet.
- The mounting structure is any form of structure as far as the structure enables mounting of the changeable controlling unit to the body, needs not to limit to a particular form of a structure, and may be a related art mounting structure. That is, as far as the mounting structure is not contrary to the object of the present invention, any form of mounting structure is acceptable. However, it is preferable that the object of the present invention can be achieved more easily by selecting an easily detachable structure.
- In providing the mounting structure and selectively mounting the changeable controlling unit to the upper portion or the lower portion of the body, a magnet which can serve as the mounting structure may be provided to the changeable controlling unit without providing the mounting structure to the body separately, so that the changeable controlling unit is mounted to the body by using the magnet. However, what is preferable is that, even in this case, the changeable controlling unit is mounted to the body more positively by providing a mounting structure to the body as a seat for attaching the changeable controlling unit.
- The word of body is a concept relative to the controller, meaning that a portion to be controlled by the controller for performing an intended function of the apparatus. For an example, the word of a washing machine body with respect to the controller is adequate as far as the washing machine body includes a washing tub for holding washing object, and a driving unit—for example, a motor and so on—for driving the washing tub to wash the washing object in the washing tub under the control of the controller. As another example, the word of a dryer body with respect to the controller is adequate as far as the dryer body includes a drum for holding laundry to be dried, and a driving unit for driving the drum to dry the laundry in the drum.
- The changeable controlling unit is electrically connected to the first connector or the second connector depending on a mounting position of the changeable controlling unit.
- If the changeable controlling unit includes the main control unit, the first connector and the second connector are electrically connected to components in the body, for example, the motor, the water supply valve, and so on.
- Therefore, the changeable controlling unit is electrically connected to the components in the body through the first connector or the second connector.
- If the main control unit is mounted in the body, and the changeable controlling unit is provided with the input unit or the display unit, the first connector and the second connector are electrically connected to the main control unit. When the changeable controlling unit is mounted to a selected position, the changeable controlling unit is electrically connected to the main control unit through the first connector or the second connector.
- Though the changeable controlling unit may include only the input unit or only the display unit, preferably the changeable controlling unit includes both the input unit and the display unit.
- In handling the controller, if the user uses, not the input unit at the body, but an external input unit provided to an outside of the body, the user will have no inconvenience in handling even if the changeable controlling unit only includes the display unit and the input unit is fixedly secured to one position the same as the related art.
- It is preferable that, if the changeable controlling unit is mounted to one of the first mounting structure or the second mounting structure, the cover panel is mounted to the other one of the mounting structures. The cover panel may be mounted by using the structure for mounting the changeable controlling unit as it is, or depending on cases, other mounting structure, such as screw fastening hole. What is important is, not that the first mounting structure or the second mounting structure is used as it is in the mounting, but that the cover panel is mounted to the other side where the changeable controlling unit is not mounted thereto.
- If the changeable controlling unit includes both the input unit and the display unit, it is preferable that the input unit and the display unit are fabricated as one body.
- The fabrication of the input unit and the display unit as one body is fabrication of the input unit and the display unit such that the input unit and the display unit can be moved together, but does not require that the input unit and the display unit are fabricated as one body even in detail, such as a PCB.
- For an example, a panel may be fabricated as one body for the input unit and the display unit, like a housing for housing detailed components of the input unit and the display unit, so that the input unit and the display unit can be moved as one.
- However, it is preferable that the input unit and the display unit are fabricated as one body even in the detailed components. For an example, respective PCBs of the input unit and the display unit may be fabricated as one body.
- Moreover, in a case the input unit is a touch screen type by using an LCD window, the input unit and the display unit are fabricated as one because the LCD window can be used for display, too.
- A jump connector or a branched cable may be used for electric connection between the components in the body and each of the first connector and the second connector. The components and the connectors may be connected with individual cables respectively. The electrical connection between the main control unit and each of the first connector and the second connector mill be described in detail, taking a case the main control unit is not included to the changeable controlling unit as an example.
- In a case the jump connector is used, the first connector and the second connector are connected to the jump connector respectively, and the jump connector is connected to the main control unit. That is, the first connector and the second connector are connected to the main control unit through the jump connector.
- Thus, by using the jump connector, the related art main control unit can be used as it is without change.
- In detail, the jump connector has two connector terminals for connection to the connectors, and a terminal for electric connection to the main control unit. The connector terminals and the terminal for the main control unit are electrically connected inside the jump connector.
- As an alternative, a branched cable may be used. The cable has one end electrically connected to the main control unit, and the other end branched into two one of which is connected to the first connector and the other one of which is connected to the second connector.
- Or, individual two cables may be used. That is, a first cable may be used for connecting the first connector to the main control unit, and a second cable may be used for connecting the second connector to the main control unit. In this instance, the main control unit is provided with a terminal for connection to the first connector and another terminal for connection to the second connector. Thus, if the first connector and the second connector are connected to respective connection portions on the main control unit individually, the related art main control unit is required to have one more terminal.
- If the changeable controlling unit is provided with both the input unit and the display unit, it is preferable that a unitized connector is provided for the input unit and the display unit, rather than providing individual connectors for the input unit and the display unit.
- More preferably, the changeable controlling unit is provided with a microcomputer for controlling devices of the input unit and the display unit. The microcomputer exchanges data with the microcomputer in the main control unit. Though the microcomputer for controlling the input unit or the display unit may be provided to the main control unit, in that case, there is a problem in that the first connector and the second connector require many electrical terminals. However, if the microcomputer for controlling the input unit or the display unit may be provided to the changeable controlling unit, a number of terminals for connection to the main control unit are reduced, significantly.
- If the user selects an operation course or the like thrash the input unit, the microcomputer in the changeable controlling unit transmits the information to the microcomputer in the main control unit. In a case of the display unit, if the main control unit transmits information on operation to a display unit microcomputer, the display unit microcomputer having the information received thus controls devices in the display unit for displaying the information.
- In the meantime, it is preferable that each of the first connector and the second connector has a connector housing of a fire-retardant material. By forming the connector housing of the fire-retardant material, for housing the electrical connection pins, the electrical connection pins are not exposed to an outside even if fire breaks out.
- The connection pins may include a pin for connection to power. If fire breaks out and components of plastic melt down to expose the connection pin to an outside, an electric shock to a user touching the pins would cause.
- Connector covers may be formed of a fire-retardant material for covering the first connector or the second connector. Accordingly, for an example, if the changeable controlling unit is connected to the first connector, the connector cover is used to cover the second connector.
- Especially, in a case the cover panel is formed of plastic, the connector cover of the fire-retardant material prevents the connection pin from exposing to an outside.
- The dual laundry machines of the present invention include a first laundry machine and a second laundry machine. At least one of the laundry machines has the changeable controlling unit. For an example, if the first laundry machine is stacked on the second laundry machine, the changeable controlling unit of the first laundry machine may be mounted to a lower portion of the body.
- In general, since a washing machine holds laundry and washing water during operation, the washing machine is heavier than the dryer and has vibration heavier than the dryer. Accordingly, in the dual laundry machines of the dryer and the washing machine, it is preferable that the dryer is stacked on the washing machine if the dryer and the washing machine are required to be stacked.
- The present invention permits to use the laundry machine without inconvenience even if the laundry machine is placed in a floor-leveled place or a higher place. Different from the related art, the laundry machine of the present invention has less limitation of an installing place.
- Particularly, in the case of the dual laundry machines having the dryer and the washing machine, the user can arrange the dryer and the washing machine side by side or stacks one on another as the case demand. The variety of arrangements will provide many effects, and particularly, the user will be less limited by location or space for placing the machine than the related art.
- In the meantime, in a case of launderette which has a large number of the dryers and the washing machines for commercial use, the present invention can be more useful. For an example, in a case the controller on one of the dryers is out of order, one controller may be transferred from another dryer to the dryer of which controller is out of order, to solve the trouble, temporarily. Or, if a body of one dyer is out of order while a controller of another dyer is out of order, the user of the launderette may transfer the controller from the dryer of which body is out of order to the dryer of which controller is out of order.
- If it is intended to change a position of the changeable controlling unit, electrical connection of the changeable controlling unit to the motor or the main control unit is simple.
- Even in a case of fire outbreak, since the connection pins of the connector or the like are not exposed to an outside, electrical accidents can be prevented.

Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
- For an example, in the embodiment, though the
changeable controlling unit 110 is detachably mounted to thebody 100 selectively, only the input unit can be detachably mounted to thebody 100 selectively while the display unit is mounted to the upper portion of thebody 100 as it is. Those are applicable to the display unit in the same fashion. - Depending on cases, the input unit and the display unit may be fabricated individually, and detachably mounted to the
body 100. - In the meantime,
FIGS. 5 and 6 illustrate dual laundry machines of the present invention, respectively. -
FIG. 5 illustrates thedryer 150 and thewashing machine 160 arranged side by side, andFIG. 6 illustrates thedryer 150 inFIG. 5 stacked on thewashing machine 160. - Since the
dryers 150 inFIGS. 5 and 6 are identical to the dryer inFIG. 2 , and the washing machines inFIGS. 5 and 6 are identical to the related art washing machine, detailed description of the dryers and the washing machines will be omitted. - In a case the
dryer 150 and thewashing machine 160 are arranged side by side as shown inFIG. 5 , thechangeable controlling unit 110 is mounted to the upper portion ofbody 100, and in a case thedryer 150 is stacked on thewashing machine 160 as shown inFIG. 6 , thechangeable controlling unit 110 is mounted to the lower portion ofbody 100. - Accordingly, the user can handle the
changeable controlling unit 110 conveniently, not to mention the case thedryer 150 and thewashing machine 160 are arranged side by side, even in the case thedryer 150 is stacked on thewashing machine 160. -
FIGS. 7 and 8 illustrate other embodiments, respectively. The laundry machine of the embodiment is almost identical to the foregoing embodiment, except that a method is different, in which themain control unit 130 is electrically connected to theupper side connector 231 and thelower side connector 241. - In the embodiment, no jump connector, but a
branched cable 250 is used. As shown, the cable has one end connected to themain control unit 130, and the other end branched in two lines. Accordingly, the two lines of branch cables are connected to theupper side connector 231 and thelower side connector 241. -
FIG. 9 illustrates another embodiment in which themain control unit 130, theupper side connector 331 and thelower side connector 341 are connected in another method. Herein, the acable 350 for connecting themain control unit 130 to theupper side connector 331 and acable 351 for connecting themain control unit 130 to thelower side connector 341 are provided, individually. -
FIG. 10 illustrates another embodiment, in which the changeable controlling unit is provided with a microcomputer. Accordingly, data exchange between the main control unit and the changeable controlling unit is made between microcomputers. - Because the changeable controlling unit is provided with a microcomputer separate from the microcomputer in the main control unit, a number of cables required for transmission of signals between the changeable controlling unit and the main control unit are reduced, substantially. In the related art, the microcomputer in the main control unit is individually directly connected to all of the elements such as buttons in the input unit or LCD window in the display unit, to require a large number of cables.
- Various kinds of information are received at the microcomputer in the changeable controlling unit through input devices such as buttons, and the microcomputer transmits the information to the microcomputer in the main control unit.
- Then, the microcomputer in the main control unit transmits information to be displayed on the display unit to the changeable controlling unit again, and the microcomputer controls display devices such as LCD window, to display the information to be displayed.
- The changeable controlling unit may be provided with a microcomputer for the input unit and a microcomputer for the display unit separately, or as one integrated.
- The laundry machine in
FIG. 10 has to microcomputers provided to the changeable controlling unit. That is, an input unit microcomputer for the input unit and a display unit microcomputer for the display unit are provided, respectively. - Input means, such as the various buttons, the knob, and so on, are connected to the input unit microcomputer, and display means, such as the LCD and LED, are connected to the display unit microcomputer.
- The
main control unit 130 has signal lines and power lines extended therefrom to theupper side connector 431 and the lower side connector (not shown). - The microcomputer (not shown) in the main control unit is connected to the
upper side connector 431 and the lower side connector through the signal lines. - The
changeable controlling unit 110 also has power lines and signal lines extended therefrom in correspondence to the signal lines and the power lines to aconnector 414. The input microcomputer (not shown) and the display unit microcomputer (not shown) in thechangeable controlling unit 110 are connected to theconnector 414 through separate signal lines. Since themain control unit 130 and thechangeable controlling unit 110 are provided with microcomputers respectively, themain control unit 130 exchanges information with and thechangeable controlling unit 110 through to signallines 83. If the input unit microcomputer and the display unit microcomputer are fabricated as one such that the changeable controlling unit has only one microcomputer, one signal line will be adequate. - Other than the two
signal lines 83, threeAC power lines 81 are used for AC power, and twoDC power lines 82 are used for DC power. - Different from the embodiment, if the changeable controlling unit is not provided with the microcomputer, since it is required that the microcomputer in the main control unit is connected to all of the various kinds of input means and all of the display means individually, a number of cables to be used will be numerous. In this case, neat arrangement of the cables will become complicate, which is inconvenient.
- If the user inputs an operation condition through the input unit, such as the buttons, in a state the
main control unit 130 is electrically connected to thechangeable controlling unit 110, the input unit microcomputer transmits information inputted thus to the microcomputer in themain control unit 130 through the signal lines. According to the input, themain control unit 130 transmits the information to the display unit microcomputer, and the display unit microcomputer controls the display means, such as the LCD window or the LED, or the like according to the information transmitted thus, to display the information. - The input unit microcomputer and the main control unit microcomputer have communication rules fixed with respect to each other. Therefore, if the input unit microcomputer transmits a signal according to the communication rules to the main control unit microcomputer, the main control unit becomes to know information the signal received thus carries. This is the same between the display unit microcomputer and the main control unit microcomputer.
- In the meantime,
FIG. 11 illustrates a case aconnector cover 99 is included to the dryer inFIG. 3 for covering theupper side connector 131 or thelower side connector 141. - The connector cover is made of a fire-retardant material.
- Referring to
FIG. 11 , thechangeable controlling unit 110 is mounted to the upper portion of the body, and thecover panel 120 is mounted to the lower portion of the body, wherein thelower side connector 141, which is not in use presently, is covered with theconnector cover 99. If thecover panel 120 is made of plastic, thecover panel 120 will be melt down in case of fire. In this instance, since thelower side connector 141 is covered with theconnector cover 99, connection pins, particularly, connection pins for connection to power source, in thelower side connector 141 are not exposed to an outside. - In a case the
changeable controlling unit 110 is mounted to the lower portion, theconnector cover 99 covers theupper side connector 131. - In the meantime, when the
upper side connector 131 and thelower side connector 141 themselves can be made of the fire-retardant material, theconnector cover 99 may not be used. - The present invention relates to laundry machines, such as dryers or washing machines, and more particularly, to a laundry machine in which a mounting position of at least an input unit or a display unit of a controller can be changed.
- The present invention permits to use the laundry machine without inconvenience even if the laundry machine is placed at a floor-leveled place or a higher place. Different from the related art, the laundry machine of the present invention has less limitation of location or space for placing the machine.
- Particularly, in the case of the dual laundry machines having the dryer and the washing machine, the user can arrange the dryer and the washing machine side by side or stacks one on another as the case demand. The variety of arrangements will provide many effects, and particularly, the user will be less limited by a located place or space than the related art.
- In the meantime, in a case of launderette which has a large number of the dryers and the washing machines for commercial use, the present invention can be more useful. For an example, in a case the controller on one of the dryers is out of order, one controller may be transferred from another dryer to the dryer of which controller is out of order, to solve the trouble, temporarily. Or, if a body of one dyer is cat of order while a controller of another dyer is out of order, the user of the launderette may transfer the controller from the dryer of which body is out of order to the dryer of which controller is out of order.
- If it is intended to change a position of the changeable controlling unit, electrical connection of the changeable controlling unit to the motor or the main control unit is simple.
- Even in a case of fire outbreak, since the connection pins of the connector or the like are not exposed to an outside, electrical accidents can be prevented.
