Description

remote control

The present invention relates to a wireless mode remote control for operating an electronic device.

In recent years, in order to operate an electronic device, a wireless remote controller is often used.

In the battery used for such a remote controller, in order to extend the period of effective use, it has been proposed to use a lithium primary battery which can take a larger current capacity, instead of using a general-purpose battery such as an alkali ‧ manganese battery. In addition, a technique for loading solar panels (solar cells) to convert solar energy into electrical energy to assist electric power has also been proposed.

When a battery that is difficult to replace, such as a lithium primary battery, is loaded, in order to suppress a decrease in serviceability or a decrease in user convenience, a general-purpose battery such as an alkali ‧ manganese battery may be used instead (for example, the patent document) 1. Patent Document 2).

Patent Document 1 discloses a technique in which a rechargeable secondary battery is loaded to supply electric power in a mobile phone, but in an environment where charging is difficult, an alkali primary battery can be loaded on a dedicated base to be used in an emergency. Further, a secondary battery is provided for the secondary battery to prevent the current from flowing back from the secondary battery.

Patent Document 2 discloses a secondary battery that is charged by a solar battery as a main driving power source. When the secondary battery as the main driving power source runs out of battery, a detachable external battery is mounted as an auxiliary driving. The technology of the electronic machine used by the source.

In recent years, due to the high environmental awareness, it has been found to provide a highly serviceable product that has a function of extending the effective use period of the battery used for the remote controller.

In Patent Document 1, a rechargeable secondary battery is mounted, and an alkaline primary battery can be mounted in an environment where charging is impossible, thereby having a function of not being affected by the use environment. However, the number of times the secondary battery is charged has its limit, and when the limit of the number of times of charging is reached, the secondary battery must be replaced. Further, since the countercurrent prevention method using the diode does not have a diode that does not leak at all, if it is used in this state for a long period of time, there is a possibility that the allowable capacity of the charging current is excessive.

In Patent Document 2, it is considered that when a secondary battery charged by a solar battery is used up due to overdischarge, that is, an external battery is loaded, and an external battery is connected to the circuit using a switch for emergency use, but since Since the driving power source uses the secondary battery that is charged by the solar battery, the secondary battery of the secondary battery is not fully obtained. The so-called battery exhaustion is inevitable, and the device cannot be used frequently. At this time, although an external battery can be used for emergency use, the external battery must be connected frequently.

In addition, when the frequency of use of the electronic device is large, under the indoor conditions in which the amount of power generation using the solar battery is not sufficiently obtained, it is assumed that the amount of power generated by the solar cell is often insufficient, and the situation is from the beginning to the end. That is to say, in the career of electronic machines, the universal battery was replaced and used. This can cause inconvenience to the user and is also not environmentally friendly. Among them, the secondary battery has a short protection of the memory effect or the number of times of charge and discharge, thereby contributing to the use of the machine and the frequency of use of the external battery.

Further, in Patent Document 2, when the frequency of use of the electronic device is small and the amount of power generation of the solar cell is sufficient, it is not necessary to load the external battery for a long period of time, but the frequency of using the changeover switch may be reduced. In this case, depending on the environment in which the electronic device is used, it is apt to rust in areas where there is a large amount of salt such as moisture, particularly in the coastal area, and it is considered to be used when it is used for auxiliary use. The possibility that the contact will be unusable due to rust due to rust.

That is, the remote controller 5 can perform the operation of the air conditioner 1 through the indoor receiving and transmitting unit 7 provided in the indoor unit 2.

<Description of remote control>

Next, the overall configuration of the remote controller 5 of the present embodiment will be described using Figs. 2 to 7 . Fig. 2 is a front view showing the appearance of the remote controller 5. Fig. 3 is a rear view showing the appearance of the remote controller 5. Fig. 4 is a side view showing the appearance of the remote controller 5. Fig. 5 is a side sectional view of the remote controller 5. Fig. 6 is a view showing the battery base of the remote controller 5. Fig. 7 is a view showing the configuration of the receiving and receiving portion of the remote controller 5.

As shown in FIG. 2, the remote controller 5 includes an operation button 10 for performing an operation instruction, a liquid crystal display screen (LCD module) 11 for displaying an operation content, and a solar battery (solar panel) 12. And a remote control receiving and transmitting unit 13 that communicates with the indoor receiving and transmitting unit 7 in two directions and is covered by the light receiving cover 13a.

As shown in FIG. 3, a battery base cover 14 is provided on the back surface of the remote controller 5.

As shown in Fig. 4, the remote controller 5 is provided with a finger-receiving portion 34 at a substantially central portion of the back surface.

As shown in Fig. 5, the remote controller 5 incorporates a lithium primary battery 32 that is a battery that is difficult to replace. Further, the remote controller 5 is provided with a battery base 15 into which a general-purpose battery is inserted and a warning card 35 inside the battery base cover 14.

Fig. 6 is a view showing a state in which the battery base cover 14 (see Fig. 3) is removed, and battery connection terminals 16, 17, 18, and 19 are provided in the battery base 15, so that the user can easily Replace the battery pack. A general-purpose battery, such as an alkali ‧ manganese dry battery, is inserted into the battery susceptor 15 to supply a power source as the remote controller 5. Here, the general-purpose battery refers to a general purchaser such as a single-three dry battery or a single-four dry battery, which can be used in a convenience store or the like.

Further, a battery changeover switch 20 is provided in the vicinity of the battery base 15.

Here, the warning card 35 shown in FIG. 5 is disposed in the battery base 15 so as to be readable by the user when the battery base cover 14 is opened. The warning card 35 is intended to be used in such a manner that the battery switching switch 20 is inserted when the battery is inserted into the universal battery, and that the lithium primary battery 32 is in a usable state, and that the general-purpose battery is not inserted. Set (the method of use when using a general-purpose battery and means to promote attention).

Fig. 7 is a view showing the configuration of the remote controller receiving and transmitting unit 13 of the remote controller 5. Fig. 7 is a view of the remote controller 5 shown in Fig. 2 viewed from the direction of the arrow A. The remote control receiving and receiving unit 13 includes an infrared light receiving element 21 and an infrared light emitting diode 22. Further, a room temperature heat resistor 23 for detecting the room temperature is placed in the vicinity of the remote control receiving and receiving portion 13, and the room temperature around the remote controller 5 can be detected at any time.

Fig. 8 is a circuit diagram showing the control configuration in the remote controller 5. The remote controller 5 is provided with a microcomputer 30 that controls the whole. An operation button 10, a liquid crystal display screen (LCD module) 11, and a transmission circuit 31 are connected to the microcomputer 30.

Power is supplied from the lithium primary battery 32 and the solar battery 12 to the microcomputer 30. The lithium primary battery 32 is connected to the microcomputer 30 via the battery changeover switch 20, the diode 41, the booster circuit 42, the diode 43 connected in parallel with the booster circuit 42, and the diode 44, and is connected to the microcomputer 30. Power is supplied (first power supply circuit).

Further, since the transmission circuit 31 supplies a large current of about 500 mA, the lithium primary battery 32 directly supplies electric power. Since the voltage drop of the lithium primary battery 32 due to the transmission circuit 31 is not affected, the booster circuit 42 is used in the first power supply circuit connected to the microcomputer 30.

The solar battery 12 is connected to the microcomputer 30 via the charging capacitor 51, the regulator 52, the battery changeover switch 20, and the diode 53, and supplies electric power to the microcomputer 30 (second power supply circuit). The diode 44 and the diode 53 constitute a diode or an OR circuit 50, and the microcomputer 30 supplies power to the microcomputer 30 from a higher supply voltage of the lithium primary battery 32 or the solar battery 12.

The battery changeover switch 20 has six terminals a, b, c, d, e, and f, and each of the terminals is formed as an effective gold contact between the slider switches 20a that are in contact with the respective terminals, and is formed as an effective gold contact. 2 circuit can be switched at the same time (2 circuit 2 contacts).

In the state of "normal time; no general-purpose battery is installed" shown in Fig. 8, the battery changeover switch 20 is connected to the terminal b and the terminal c by the slider switch 20a, and connects the terminal e and the terminal f. In other words, the microcomputer 30 is connected to the terminal c via the terminal b, and can supply electric power from the solar battery 12, and the terminal e can be connected to the terminal f to supply electric power from the lithium primary battery 32.

As shown in Fig. 8, the electric power for operating the remote controller 5 is mainly the lithium primary battery 32, and is supplied by the solar battery 12. Here, as usual, as shown in Fig. 8, the battery base 15 is in an empty state.

In the configuration shown above, when the indoor illumination using the remote controller 5 is high and the amount of power generation of the solar battery 12 can be sufficiently ensured, the solar battery 12 is required to bear a part of the load current, for example, the load current of the microcomputer 30 in the standby mode, and is not performed. The power supply from the lithium primary battery 32 functions to extend the battery life of the lithium primary battery 32.

Further, in order to extend the battery life of the lithium primary battery 32, the microcomputer 30 stops the display of the liquid crystal display screen 11 when the remote controller 5 is not in use, that is, in the standby mode, and performs control for reducing the load current.

Here, the setting to the standby mode is, for example, the input of the operation button 10 is less than three hours, and the like, and the standby mode is moved by detecting the unused state. Among them, the setting to move to the standby mode is not limited to three hours, and can be set in units of day, day, or minute, such as one day, two days, and three days, mainly if the user's convenience can be ensured while moving. To save energy mode.

In addition, the remote controller 5 can sense the change in the electrostatic capacitance, that is, whether the hand of the person touches the remote controller 5, and the movement of the standby mode can be set by the presence or absence of the sensing. Further, a cover portion may be provided in the remote controller 5, and the movement of the standby mode may be set by opening and closing the cover portion.

In addition, the reason why the lithium primary battery 32 is used as the main power source and the solar battery 12 is used in combination is that the remote control is not used even if the illuminance of the room is low and the amount of power generation of the solar battery 12 is insufficient. In order to prevent the use of the air conditioner 1 from being restricted, the convenience of the user can be maximized.

In addition, in general, a small amount of charging current is found with respect to the lithium primary battery system, but since there is a limit, it is necessary to reduce the charging current as much as possible. Therefore, in the circuit shown in Fig. 8 of the present embodiment, when the lithium primary battery 32 and the solar battery 12 are used in combination, the solar battery 12 is not configured to flow a charging current to the lithium primary battery 32.

<Description when using a general-purpose battery>

As described above, even if the remote controller 5 that supplies electric power from the lithium primary battery 32 and the solar battery 12 uses the lithium primary battery 32 having a large current capacity, there is a certain battery life. In the case where the frequency of use is much larger than assumed, it is assumed that the lithium primary battery 32 is overdischarged within the life of the air conditioner 1.

However, in general, the battery replacement system of the lithium primary battery 32 built in the remote controller 5 requires a relatively specialized technique, and therefore it is generally necessary to avoid battery replacement by the user.

Therefore, in the present embodiment, a configuration is adopted in which a general-purpose battery such as an alkali ‧ manganese battery can be mounted. That is, as shown in Fig. 6, a configuration is adopted in which a general-purpose battery such as an alkali ‧ manganese battery can be inserted into the battery susceptor 15 . When the general-purpose battery is inserted, the switch of the battery changeover switch 20 is switched, and the electric power from the lithium primary battery 32 and the solar battery 12 is supplied, and the circuit connection is switched to the power supply from the general-purpose battery.

Fig. 9 and Fig. 10 are diagrams showing the circuit configuration when the universal battery 33 is inserted into the battery base 15.

Fig. 9 shows a state in which the lithium primary battery 32 and the solar battery 12 are connected to the battery changeover switch 20 of the microcomputer 30.

Fig. 10 shows a state in which the universal battery 33 is connected to the battery changeover switch 20 of the microcomputer 30.

In the state of "When the general-purpose battery is placed" shown in Fig. 9, the battery changeover switch 20 is connected to the terminal b and the terminal c by the slider switch 20a, and connects the terminal e and the terminal f. In other words, the microcomputer 30 can supply electric power from the solar battery 12 by connecting the terminal b and the terminal c, and the power supply from the lithium primary battery 32 can be made possible by connecting the terminal e and the terminal f.

In the state of "When a general-purpose battery is used" shown in Fig. 10, the battery changeover switch 20 is connected to the terminal b by the slider switch 20a to be switched, and the terminal d is connected to the terminal e. In other words, the microcomputer 30 is connected to the terminal e via the terminal d, and only the power supply from the general-purpose battery 33 can be performed (the third power supply circuit). In other words, at this time, the terminal cell a is connected to the terminal b, and the solar cell 12 is formed in a state in which it is not connected to the microcomputer 30, and is formed in a state in which the terminal f is not connected. Therefore, the lithium primary battery 32 is also formed not. The state in which the microcomputer 30 is connected.

As a result, the connection between the solar cell 12 and the lithium primary battery 32 to the microcomputer 30 is completely separated.

Here, when the universal battery 33 is inserted into the battery base 15, the battery changeover switch 20 may be disposed such that the solar battery 12 and the lithium primary battery 32 are automatically switched to the inserted universal battery 33. At this time, the convenience of the user can be further enhanced.

Further, the general-purpose battery 33 such as an alkali ‧ manganese battery is different from the lithium primary battery 32 and does not allow charging current at all. Therefore, even if a current leakage is prevented by a diode or the like, leakage current cannot be completely prevented. Therefore, in the present embodiment, when the general-purpose battery 33 is used, the circuit of the lithium primary battery 32 and the solar battery 12 is completely blocked by using the battery changeover switch 20, whereby the charging current can be prevented from flowing through the general-purpose battery 33.

Further, the battery changeover switch 20 is configured to simultaneously switch between two circuits, and is configured to simultaneously switch between a circuit connected to the lithium primary battery 32 and a circuit connected to the solar battery 12. Prevents erroneous operations.

Further, when the lithium primary battery 32 has a residual amount, the lithium primary battery 32 built in the remote controller 5 is partially loaded by the solar battery 12, and stops the display of the liquid crystal display screen 11 in the standby mode, and consumes The current suppression is low, so that the usable state can be maintained without overdischarging for a long time. Therefore, the opportunity to insert the universal battery 33 for use is after a very long time.

Further, in general, the switching relationship is mechanically and electrically refreshed by opening and closing the contacts. However, in the present embodiment, the life of the lithium primary battery 32 is extended as described above, and the battery switching switch 20 is used. The frequency is extremely low, and the time point used is such that after a very long time elapses, the contact update caused by the opening and closing of the contact cannot be expected, and the contact due to the rust of the contact may be defective. The rust of the contact is more serious in the coastal areas where the salt in the air is more floating. In the present embodiment, the gold contact which does not have rust is used in the battery changeover switch 20 to achieve rust prevention.

Among them, the reason why the primary primary battery 32 is placed in the primary battery of the remote controller 5 is that the capacity can be increased at a relatively low cost, and the economic burden on the user can be reduced. Further, in the selection of the primary battery suitable for the built-in, even if a primary battery other than lithium is used, the same effect can be obtained.

Further, when the general-purpose battery 33 is used, the warning card 35 in which the method of using the battery changeover switch 20 for switching the power supply circuit is described is stored in the battery susceptor 15 in advance, and the method of use is correctly transmitted to the user. The lithium primary battery 32 is in a usable state, and is prevented from being erroneously inserted into the general-purpose battery. Further, when the general-purpose battery is used after the lithium primary battery 32 is over-discharged, the use of the battery changeover switch 20 for switching the battery is first described on the warning card 35, so that the correct operation can be promoted.

Fig. 11 shows a configuration of a battery susceptor 15 which does not have the power supply switch 20 and the universal battery 33 as a comparative example.

According to the present embodiment, even if a primary battery that is difficult to replace is built in, the battery can be easily replaced by a user (general battery), and the serviceability can be improved, and the remote controller can be continuously used. As a result, the air conditioner can be achieved. Long-term use during the effective use period.

In addition, it is possible to achieve a long-term period of effective use of the primary battery built in the remote controller, and to replace the battery to improve the serviceability, and to take into consideration the remote control of the global environment.
