Thus, the traffic is kept to a proper quantity and the signal collision with other system is less and efficient signal transmission is attained. Moreover, the device control data inputted from a key input means 4 is displayed on a detection means 3 such as a liquid crystal display element and the content is sent in the lump, then the display content of the remote controller itself is changed as required without intervention of the operator.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wireless remote control device for remotely controlling household equipment such as gas water heaters and oil boilers using radio waves.

2. Description of the Related Art A conventional wireless remote control device of this type is generally an infrared remote control for a television receiver.

Problems to be Solved by the Invention However, in the case of such an infrared remote control, it is naturally impossible to perform remote control across a wall. Therefore, it is possible to realize remote control across walls using a wireless remote control device that uses radio waves. However, wireless remote control devices that use radio waves have the following problems.

(1) Since radio signals pass through walls, for example, in a configuration such as an infrared remote control for a television receiver that transmits every time a key is pressed, traffic increases and signals from other systems are transmitted. The probability of collision increases.

(2) Similarly, if a transmission is performed every time a key is operated, power is consumed, so in the case of a battery-powered remote control, the battery life will be shortened.

Note that FIG. 5 is a timing diagram showing the operation of the conventional remote control device, and in response to the key operation in FIG.
A radio signal is emitted at the timing shown in b).

The present invention solves such conventional problems, and aims to provide a practical wireless remote control device using radio waves that solves the problems of trough ink and power consumption while minimizing deterioration in operability. shall be.

Means for Solving the Problems In order to solve the above problems, the wireless remote control device of the present invention includes a transmitting means for transmitting signals using radio waves, and a control for setting control contents for controlling the main body of the device. The apparatus is equipped with a data setting means and a dedicated transmission operation means for transmitting the set control data by the transmission means.

Further, in the present invention, the control data setting means is composed of a display means such as a liquid crystal display element and a key input means, and after displaying all the control contents on the display means by key input operation before sending, It is equipped with a remote control control means that transmits control data all at once by operating the operation means.

Further, the present invention includes a control data storage means for storing previously transmitted control data, a control timer means for starting time measurement after initialization when the key input means is inputted, and remote control control means configured to display the contents of the control data storage means on the display means if the transmission operation means is not operated within a predetermined time limited by the limit timer means after the setting operation is performed by the means; It is something that

Furthermore, the present invention includes a receiving means for receiving a response signal from the main body of the Il device, and when the receiving means cannot receive the response signal from the main body of the device after the control data is transmitted by the transmitting means, the The apparatus includes a remote control control means configured to display the contents of the control data storage means on the display means.

Furthermore, the present invention is provided with a busy display means for displaying that transmission/reception is in progress, and a remote control control means configured to disable the operation of the transmission operation means during the busy display.

Effect of the Invention With the above-described configuration, the present invention transmits by operating the transmission operation means after all control details have been set, so that radio signals are not unnecessarily emitted into space. As a result, traffic is maintained at an appropriate amount, and signal collisions with other systems are reduced, allowing efficient signal transmission.

In addition, the device control data input from the key input means is displayed on a display means such as a liquid crystal display element, and the contents are transmitted all at once, so the data can be transmitted as needed without operator intervention. The remote control device itself can change the displayed content. For example, if the transmitting operation means is not operated within a predetermined time after setting the device control data, the displayed content can be returned to the control data previously transmitted to the device main body.

Furthermore, if the remote control device has a receiving means, it is possible to easily return the display contents to the previous state even if the device control data is transmitted but no response signal is received from the device itself. Become. These actions make it possible to ensure consistency between the display content of the remote control device and the operating state of the main body of the device.

Further, since a busy display is displayed during transmission/reception, the operator can avoid operating the transmission operation means during transmission/reception, improving usability.
