1. Field of the Invention
The present invention relates to a home appliance, and more particularly, to a home appliance having a radio reception function.
2. Discussion of the Related Art
Generally, a washing machine is an electric home appliance, which is most widely used in homes to remove contaminants attached to laundry such as clothes by utilizing a softening action of detergent, a frictional action of wash water flows resulting from a rotational action, an impact of the wash water flows applied to the laundry, etc.
For such washing machines, products of various washing types, for example, a pulsator type, agitator type, drum type, etc. are commercially available. Such washing machines may also be classified into a separation type and a full automation type in terms of whether or not washing and spin-drying tubs are separated from each other.
For most washing machines, the user uses the washing machines by properly setting washing conditions, such as a washing time, rinsing time and spin-drying time, according to the materials or amount of laundry.
A plurality of washing course programs are pre-stored in a memory so that they may be selectively utilized by the user to perform automatic washing for the user's convenience.
For example, a variety of washing course programs, such as centrifugal washing, high-concentration washing, prewashing, vibration washing, annealing washing and wool washing, may be pre-stored in the memory so that the user can simply and conveniently select a desired washing course to execute the automatic washing.

The washing machine body 100 further includes a personal communication unit (a personal computer (PC), handheld device or the like) capable of performing Internet communication. The communication unit enables the user to use, over the Internet, a variety of services including downloading washing course programs.
The radio module 200 is adapted to receive a radio frequency (RF) signal. To this end, the radio module 200 includes a key input unit 220 for inputting a power, volume and frequency of the radio module from the user, a display unit 250 for displaying the volume and frequency inputted through the key input unit 220, an RF receiver 210 for receiving an RF signal corresponding to the frequency inputted through the key input unit 220, a radio controller 240 for processing the RF signal received by the RF receiver 210 to convert it into an audio signal that can be outputted, and an audio output unit 260 for outputting the audio signal from the radio controller 240.
In the present first embodiment, the radio module 200 is installed in the side or top plate of a cabinet constituting the outer appearance of the washing machine body 100 in a folded manner.
In detail, the RF receiver 210 and the radio controller 240, among the constituent elements of the radio module 200, are disposed inside the washing machine body 100 for efficient spatial utilization thereof, and the display unit 250 and the audio output unit 260 are disposed outside the washing machine body 100 under the condition of being physically separated from the radio controller 240.
That is, the arrangement of the radio module 200 provided on the outer surface of the washing machine body 100 corresponds to the key input unit 220, display unit 250 and audio output unit 260, as shown in
The washing controller 140, provided inside the washing machine body 100, and the radio controller 240 are interconnected via a serial communication line such that data communication is enabled between the washing machine body 100 and the radio module 200.
With this configuration, while the washing mode is performed by the washing machine body 100, the current washing progress state can be outputted by the audio output unit 260 of the radio module 200 through the data communication between the washing machine body 100 and the radio module 200.
The washing machine according to this first embodiment further comprises a remote controller 300 for inputting control commands to the washing machine body 100 and radio module 200. A key panel for control of the washing machine body 100 and a key panel for control of the radio module 200 are together provided in the remote controller 300 so that the remote controller 300 can be used for both the washing machine body 100 and radio module 200.

A code format of the washing machine body 100 and a code format of the radio module 200 are together provided in the remote controller 300 so that the remote controller 300 can transmit a key code based on the corresponding code format of a key panel operated by the user.
The washing machine body 100 and the radio module 200 further include infrared receivers 130 and 230, respectively. Each of the infrared receivers 130 and 230 acts to receive a key code transmitted from the remote controller 300.
With this configuration, the infrared receivers 130 and 230 receive key codes transmitted from the remote controller 300 and transfer the received key codes to the washing controller 140 and radio controller 240, respectively. At this time, the washing controller 140 and radio controller 240 recognize only key codes of the code formats corresponding thereto.
A description will hereinafter be given of the operation of the first embodiment of the washing machine with the radio reception function according to the present invention, constructed as stated above.
First, in the washing machine body 100, the washing controller 140 controls the load driver 160 to drive loads necessary for the washing mode in consideration of washing mode conditions inputted by the user or mode states sensed by the sensor unit 120.
At this time, the washing controller 140 displays current mode conditions in progress or a current washing progress state through the display unit 150 of the washing machine body 100.
Further, the washing controller 140 transfers information regarding the current washing progress state to the radio controller 240 through communication with the radio controller 240.
Meanwhile, in the radio module 200, if the user turns on the power of the radio module 200 through the key input unit 220 and then inputs a desired radio frequency and a desired radio volume through the key input unit 220, the display unit 250 displays the radio volume and frequency inputted through the key input unit 220.
Then, the RF receiver 210 receives a radio broadcast signal corresponding to the radio frequency inputted by the user and transfers it to the radio controller 240.
The radio controller 240 receives the radio broadcast signal from the RF receiver 210, processes it to convert it into an audio signal that can be outputted, and then outputs the converted audio signal to the audio output unit 260.
As a result, the audio signal of the frequency selected by the user is outputted through the audio output unit 260, so that the user can listen to a desired radio broadcast.
On the other hand, the radio controller 240 receives information regarding a current washing progress state of the washing machine body 100 through communication with the washing controller 140 and processes the received washing progress state information to convert it into an audio signal that can be outputted through the audio output unit 260.
For example, when a mode error, such as washing eccentricity, occurs in the washing machine body 100 or the washing mode is ended, the resulting signal is transmitted from the washing controller 140 to the radio controller 240 and then outputted through the audio output unit 260 of the radio module in the form of a voice notification message or buzzer sound under the control of the radio controller 240.
Therefore, according to the present first embodiment, the radio module is installed in the washing machine integrally therewith so that the user can listen to the radio through the washing machine. Also, the washing progress state of the washing machine can be outputted through the audio output unit of the radio module.
On the other hand, recently, with the increase in the living space of a house, a washing machine or drying machine (referred to hereinafter only as a “washing machine”) is on a trend of being installed and used in a separate place distant from the living space, such as the outdoors or the basement of the house.
In the case where a washing machine is installed away from the living space like this, the user has to frequently visit a place where the washing machine is installed, to control the washing machine or monitor the operation state thereof, resulting in an inconvenience to the user.
In order to overcome this problem, recently, research has been done for a remote control technique capable of controlling a washing machine installed away from the living space of the user or monitoring the operation state thereof.
A second embodiment of the home appliance with the radio reception function according to the present invention will hereinafter be described with reference to
In the second embodiment, the washing machine body 100 is installed in a separate space, such as the outdoors or the basement of a house, to periodically transmit information regarding a current washing progress state through power line communication.
In contrast, the monitor device, denoted by reference numeral 400, is installed in the living space of the house such that it can be more readily used by the user.
Thus, the monitor device 400 can not only remotely control the distant washing machine body 100 from within the house through the power line communication with the washing machine body 100, but also check the state information transmitted from the washing machine body 100 and output the washing progress state including washing mode conditions, the remaining mode time, mode errors, mode start/end, etc. in various forms (image or audio).
The present second embodiment is characterized in that the radio reception function is additionally provided in the monitor device 400 which is means for the remote control of the washing machine body 100.
To this end, the monitor device 400 includes a key input unit 220 for inputting a washing machine control command and a control command for the radio reception function from the user, a communication unit 270 for transmitting the washing machine control command to the washing machine body 100 or receiving state information of the washing machine body 100 therefrom through the power line communication with the washing machine body 100, an RF receiver 210 for receiving an RF signal, a display unit 250 for displaying the state information of the washing machine body 100 and a radio volume/frequency, an audio output unit 260 for outputting the state information of the washing machine body 100 and the RF signal in the form of audio signals, and a monitor controller 240 for performing the power line communication with the washing machine body 100 or the radio reception function in response to a control command from the user.
The communication unit 270 is a communication module capable of performing the power line communication, for example, a power line modem. This communication unit 270 can perform data communication with the washing machine body 100 without using a network such as a gateway or a communication network such as the Internet.
The monitor controller 240 is equipped with an application program to perform the radio reception function through a radio circuit (not shown) included therein, as well as the data communication with the washing machine body 100.
The monitor device 400 includes the audio output unit 260 to output the RF signal, as well as the state information of the washing machine body, in the form of audio signals. The audio output unit 260 is installed in the side or front plate of a cabinet constituting the outer appearance of the monitor device 400.
The display unit 250 includes a liquid crystal display (LCD) to display the state information of the washing machine body 100 and the radio volume/frequency.
The key input unit 220 is adapted to receive a control command signal based on a key operation of the user and transfer it to the monitor controller 240. A key panel for washing-associated control and a key panel for control of the radio reception function are together provided in the key input unit 220.
In order to remotely control the monitor device 400, a remote controller (not shown) may be provided which has the same key panels as those of the key input unit 220.
A description will hereinafter be given of the operation of the second embodiment of the washing machine with the radio reception function according to the present invention, constructed as stated above.
First, the user turns on the power of the monitor device 400 through the key input unit 220 and then inputs a desired radio frequency and a desired radio volume through the key input unit 220.
At this time, the display unit 250 displays the radio volume and frequency inputted through the key input unit 220.
Then, the RF receiver 210 receives a radio broadcast signal corresponding to the radio frequency inputted by the user and transfers it to the monitor controller 240.
The monitor controller 240 receives the radio broadcast signal from the RF receiver 210, processes it to convert it into an audio signal that can be outputted, and then outputs the converted audio signal to the audio output unit 260.
As a result, the audio signal of the frequency selected by the user is outputted through the audio output unit 260 of the monitor device 400, so that the user can listen to a desired radio broadcast.
On the other hand, the monitor controller 240 receives the state information of the washing machine body 100 therefrom by performing the power line communication with the washing machine body 100 through the communication unit 270. The monitor controller 240 then not only displays the received state information, but also outputs it in the form of an audio signal as needed.
For example, when a mode error, such as eccentricity, occurs in the washing machine body 100 or the washing mode is ended, the resulting signal is transmitted to the monitor controller 240 and then outputted through the audio output unit 260 in the form of a voice error message or buzzer sound under the control of the monitor controller 240.
Meanwhile, upon receiving emergency state information, such as a mode error, from the washing machine body 100 in the middle of performing the radio reception function, the monitor controller 240 may suspend the RF signal output and preferentially output an audio signal corresponding to the received state information.
Therefore, according to the present second embodiment, the radio reception function is additionally provided in the monitor device which remotely controls the home appliance. Therefore, the user can listen to the radio through the monitor device.
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.
