Problems solved by technology

[0020] Especially in the case of an air conditioner, where there are no operation buttons in the equipment to be operated and the equipment to be operated can only be operated by the remote controller, the following problems will occur: when the power supply of the remote controller is used as a built-in secondary When the battery is used, if the secondary battery is discharged, not only the remote control but also the operating equipment such as the air conditioner cannot be used until the secondary battery is fully charged.

Embodiment Construction

[0047] Hereinafter, modes for carrying out the present invention (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings.

[0048] First, use figure 1 The overall structure of the air conditioner 1 operated by the remote controller 4 of this embodiment is demonstrated. figure 1 It is a block diagram of the air conditioner including the remote controller of this embodiment. An air conditioner 1 for air conditioning indoors includes: an indoor unit 2 installed indoors; an outdoor unit 3 installed outdoors; a remote controller 4 for remotely operating the air conditioner 1; Piping8.

[0049] The indoor unit 2 includes an indoor heat exchanger (not shown) at the center of the cabinet base 21, and a cross-flow fan type indoor blower having a length approximately equal to the width of the indoor heat exchanger on the downstream side of the indoor heat exchanger. (not shown), and a dew receiving pan (not shown) for receiving dew cond...

Abstract

The invention provides a remote controller which is safe and capable of improving the service lifetime of cells, and an air conditioner having the remote controller. The remote controller is provided with a solar cell; a secondary battery storing power sent by the solar cell and providing the power to a load; a primary battery supplying power to the load; and a switch connecting with the primary battery and working by utilizing potential difference between the primary battery and the second battery. The switch is composed of a field effect transistor. One or more antireflux diodes connect a grid electrode of the field effect transistor and a positive electrode of the secondary battery. Thus, the controller which is safe and capable of improving the service lifetime of cells is provided.

Description

technical field [0001] The present invention relates to a wireless remote controller and an air conditioner provided with the remote controller. Background technique [0002] Devices in many fields have disclosed technologies in which solar cells are installed, and solar energy is converted into electric energy, and a built-in secondary battery is charged and used as a power source. The following discloses a technology that can use a device when the charging power of the secondary battery is reduced, particularly by using a backup power source. [0003] Patent Document 1 discloses a backup power supply device in which a Schottky barrier diode is connected to a backup primary battery, and a resistor is connected in parallel to the primary battery, thereby reducing the current flowing into the primary battery. [0004] In addition, Patent Document 2 discloses a method of controlling the output of a backup battery using a reset IC and a switching circuit. [0005] In addition...
