Formed is characterized in consisting of a central processing unit for controlling.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary installation diagram of the water purifier of the present invention, FIG. 2 is a control configuration diagram of the water purifier of the present invention, and FIG. 3 is a circuit diagram showing an embodiment of the wireless / ordinary telephone selection change of the present invention.

The present invention, in the conventional water purifier 1 shown in Figure 1, one side of the main body of the water purifier 1 is provided with a radiotelephone equipped with a transmission and reception antenna (A2) for wireless communication with the outside, the radiotelephone A speaker 13 and a microphone 11 for making a call with an outsider are provided, and also a key 14 for changing a wireless / general phone selection, a display 12 for indicating various states of a water purifier and a telephone, and a telephone number The keypad 15 is installed.

In addition, it is connected to the subscriber line connected to the trunk line 4, and is provided with a fixing device (2) for transmitting and receiving the signal received from the subscriber line in the air through the antenna A1.

The fixing device 2 is provided with a jack 22 to be connected to the general telephone 3 to one side, as well as a separate power source is required because it can not receive a current of a predetermined standard or more from the trunk line (4).

As shown in FIG. 2, a detailed control diagram of the wireless telephone function is added. That is, (2) is a fixed device, which is connected to the subscriber line, the inside of the hole drill relay is configured to form a connection between the wireless telephone and the subscriber line and the line interface unit 21, the call path of the line interface unit 21 The first transmitting and receiving audio unit 22 which transmits and receives and transmits audio to and from the first wireless unit 23 and the first wireless unit which transmits the audio signal of the first transmitting and receiving audio unit 22 as an electrical signal when formed. It consists of 23.

(1) is a water purifier including a cordless telephone, a pressure water level detecting unit 107 for detecting the pressure level of the water purifier, a water level detecting unit 106 for detecting the water level of the water purifier, step-up pump driving unit 104, solenoid valve The well-known integer control part comprised by the drive part 105 is included, The key input part 103 which inputs a telephone numeric keypad signal and a radio / regular telephone change as a key signal, and the signal of the 1st wireless part 23 of the said fixing device. And a second transmitting and receiving audio unit 101 which transmits and receives a signal of the second wireless unit 107 and transmits and receives a signal of the second wireless unit 107 to form a call loop with the microphone 11 and the speaker 13. The communication circuit is controlled according to the transmission / reception signal of the second transmission / reception audio unit 101 to form and control a call loop with the microphone 11 and the speaker 13.

FIG. 3 is a circuit diagram showing an embodiment of the present invention for changing the wireless / general telephone selection. The terminal NC of the hole drill 211 terminal of the line interface unit 21 connected to the subscriber lines a and b is connected to the general telephone 3. ), And the other terminal NO is connected to the first transmission / reception audio unit 22. Here, the first transmission / reception audio unit 22 includes a bridge diode B, a zener diode ZD, a resistor R, and an amplifier 221 and 222.

Here, it is preferable that the terminal switching of the hole drill ray 211 is changed according to the control signal of the central processing unit 102.

Referring to the operation of the present invention configured as described above are as follows.

Since the technology related to the normal water purifier use is a known technique, a detailed description thereof will be omitted.

First, when the general telephone 3 is connected to the jack 22 of the fixing device 2, the initial state of the line-in-face unit 21 is the C-NO connection of the terminal of the hole drill ray 211. It serves as a wireless telephone in which signals applied from the trunk lines a and b are wirelessly transmitted and received.

That is, when the phone number keypad 15 of the key input unit 103 is operated so that the fixing device 2 receives an external incoming call or performs an external call, the signals of the subscriber lines a and b are held. It is applied to both ends of the bridge diode B through the relay 211, and the bridge diode B is connected to the amplifiers 221 and 222 through a zener diode ZD as a voltage source and a resistor R as a current source.

Accordingly, the RF transmission audio signal generated by the microphone 11 of the radio telephone and generated through the second transmission / reception audio unit 101 is transmitted to the second wireless unit 107 and the first wireless unit 23 of the fixing device 2. After converting into an electrical signal through the receiving amplifier 221 is amplified and sent to the subscriber line (a, b), the received audio signal through the subscriber line (a, b) is amplified by the transmission amplifier 222 After that, it is modulated into an RF signal through the second wireless unit 107 and transmitted to the wireless telephone of the water purifier, and the audio is obtained through the speaker 11 through the second transmission / reception audio unit 101.

On the other hand, when the telephone (3) is connected to the jack 22 of the fixing device (2) when the wireless / normal telephone mode key 15 signal is input to the central processing unit 102, the central processing unit (102) is held. Change the terminal of the relay 211 to C-NC. Accordingly, the signal applied from the subscriber station lines a and b is immediately applied to the general telephone 3 to form a call loop as the general telephone.

Of course, if a change signal of the wireless / general phone key 14 is input during the call to the wireless telephone, the telephone can be switched to the general telephone.

As described above, the present invention, as well as the ordinary water purification function, by providing the subscriber line and the telephone as a device capable of wireless communication, it is possible to remove the telephone line connected to the conventional subscriber line by wire, the appearance is beautiful In addition, there is a feature that can be used in parallel with a general telephone.

The above description is only one embodiment of the present invention, and any change may be made within the scope of the present invention.
