  However, in conventional housing equipment, when a remote control has a TV screen, it is difficult to directly receive a TV broadcast image signal with a remote control installed in a room such as a kitchen or bathroom because of the quality of the image and sound. The TV remote antenna cable work had to be performed on the remote control, and there was a problem that the cable remote control was not necessary and the features of the wireless remote control with high portability could not be exhibited.

  The present invention solves the above-described conventional problems, and an object thereof is to provide a radio remote controller with a television screen that eliminates the need for dedicated antenna cable work.

  In order to solve the above-mentioned conventional problems, the housing equipment of the present invention is provided between a relay unit connected to a device body by a cable line and transmitting and receiving in a wired manner, and a remote controller having a device state display screen and a television screen. The device control signal and the monitor signal, and the television image signal and the tuner control signal are transmitted and received in the same frequency band.

  As a result, the TV broadcast signal can be satisfactorily received from the antenna provided on the device installed outdoors, and the control signal and monitor signal of the device, the TV image signal and the tuner control signal can be transmitted and received in the same frequency band. Thus, the radio transmission / reception circuit can be simplified.

  As described above, according to the present invention, it is not necessary to construct an antenna cable dedicated to a television set for the remote control, and therefore, there is an advantageous effect that a wireless remote control with a television screen having a high portability can be provided. Since the television image signal and the tuner control signal are transmitted and received in the same frequency band, the wireless transmission / reception circuit can be simplified, and the television function can be added to the remote control at a relatively low cost.

An apparatus for receiving a TV broadcast radio wave and a tuner for TV broadcast radio waves, the remote control having a device status display screen and a TV screen, and the device between the repeater and the remote control. A control signal and monitor signal, and a TV image signal and a tuner control signal are transmitted and received in the same frequency band, and is better than the TV broadcasting radio wave receiving antenna of the device body installed outdoors. Radio waves can be received, and the control signals and monitor signals of the devices are transmitted to the remote control via the TV broadcast radio tuner and the repeater. By transmitting radio waves in one frequency band, it is possible to provide a portable radio remote controller with a TV screen that does not require a TV antenna cable work for the remote controller with a simple wireless transmission / reception circuit of the repeater and the remote controller. .

  According to a second aspect of the present invention, the device status display screen provided on the remote control and the television screen are made the same screen, and the screen display contents are switched with each other by a switch provided on the remote control, so that the screen mounted on the remote control is single. Thus, the screen can be made relatively large, and the remote control itself can be made inexpensive.

  The third invention displays the device status display in the corner on the TV screen as character information, thereby confirming the operation status of the device while the TV screen is displayed without operating a complicated screen switching switch. be able to.

  According to a fourth aspect of the present invention, device state display characters can be turned on / off on a television screen by using a switch provided on a remote controller, so that device state display characters that interfere with television viewing are not arbitrarily displayed. be able to.

  In the fifth aspect of the invention, only a TV screen is displayed, and a specific state of the device is displayed only for a certain period of time, thereby alerting the user in driving the device even while watching the TV. Information to be transmitted can be transmitted.

  In a sixth aspect of the present invention, when a change in the operating state of a device occurs while only the TV screen is displayed, the state change content is notified only by voice, so that even if the user is watching TV, It is possible to alert the user about changes in the operating state of the water heater without any change.

  According to a seventh aspect of the present invention, when a change in the operation state of the device occurs with a switch provided on the remote controller, the device state display is displayed as character information on a part of the television screen, or the state change content is displayed by voice. It is possible to select whether to display on a part of the TV screen according to the contents of the TV broadcast program or to notify the contents of the state change by voice by enabling the switching of the notification. The user can be alerted about changes in the operating state of the device without being in the way.

  According to an eighth aspect of the present invention, among the signals transmitted and received from the device to the remote controller, the device control signal and the monitor signal are in the same frequency band for the device, and the tuner control signal and the television image signal are separated from the device frequency. By transmitting and receiving in the same frequency band for TVs, even if device control signals and monitor signals are transmitted and received while the TV screen is displayed, the TV screen and sound are not disturbed, the image is stopped, and the sound is not interrupted. it can.

  The ninth invention is a device installed indoors or a device in an installed state that cannot receive TV broadcast radio waves well even outdoors, by providing a TV broadcast radio wave receiving antenna and a TV broadcast radio wave tuner in the repeater. However, it is possible to receive a good TV broadcast by moving only the repeater to a position where the TV broadcast radio wave can be satisfactorily received.

  The tenth aspect of the invention includes an antenna cable connection terminal instead of the TV broadcast radio wave reception antenna, and can be distributed and connected with a cable from the TV broadcast reception antenna installed on the roof or roof of the house. In addition to receiving TV broadcast radio waves, the device does not require a TV receiving antenna and can be made inexpensive.
