Description

  The present invention relates to an ecosystem, a power control apparatus, and a home appliance that operate a home appliance with at least the reusable power among grid power such as reusable power and commercial power generated by solar power generation.

  In recent years, interest in ecology (energy conservation) has increased from the viewpoint of protecting the global environment. In addition, efforts to realize eco-friendliness and a believable attitude are becoming established. For this reason, it is expected that eco-friendly efforts will be made in all fields in the future.

  For example, Patent Document 1 discloses a control device for a vehicular generator that promotes charging of a battery by increasing a generated voltage of the generator in a vehicle deceleration state. In this technology, when the power generation amount is likely to exceed the capacity of the battery in the energy regenerative brake, the surplus power generation amount is used to work the heating unit which is one of the electric loads.

  Further, Patent Document 2 discloses a technique for preventing economic deterioration in a facility that uses a private power generator to cover a part of electric power. In this technology, it is described that an air conditioner that obtains electric power from at least one of a commercial power source or a private power generation device operates by switching between a normal operation mode and a private power generation operation mode in which the driving ability is regulated. .

  Among home appliances, for example, in a liquid crystal television device (hereinafter simply referred to as “liquid crystal television”), the cause of increasing power consumption is a liquid crystal backlight or a CPU (Central Processing Unit). There is an increase in the load. The load on the CPU largely depends on the bit rate of the reproduced video. For this reason, in a liquid crystal television, power consumption can be reduced if the brightness of the backlight and the bit rate of the reproduced video can be lowered.

  However, home appliances have an aspect of realizing a comfortable living environment. Therefore, it is impossible to realize a comfortable living environment simply by realizing ecology. For example, in a liquid crystal television, if a low-quality image is displayed with emphasis only on ecology, the user's satisfaction cannot be improved, and the attractiveness as a product is also reduced. Accordingly, it is desired to realize a high quality image while realizing ecology.

  In the technique described in Patent Document 1, when more power is generated, it can be evaluated not to throw it away but to use it effectively. However, since gasoline energy, which is a depleting energy, is used, the viewpoint of protecting the global environment Is not taken into account. In the technology described in Patent Document 2, when the amount of private power generation decreases and commercial power must be used, the economy can be improved by operating in the energy saving mode. There is no point of view and no consideration is given from the point of user satisfaction.

Can be increased, at least one of the number or quality of functions performed by the home appliance is increased, and when the consumption of reusable power cannot be increased, the home appliance performs It is characterized in that at least one of the number of functions or quality is reduced.

  In this way, if the consumption of reusable power can be increased, it increases the number or quality of the functions performed by the home appliance, so that when operating the home appliance, Higher functions can be exhibited within a range that does not affect the operation. On the other hand, when the amount of reusable power consumption cannot be increased, at least one of the number or quality of functions performed by the home appliance is reduced. Therefore, when operating the home appliance, the power consumption is reduced. It becomes possible to realize ecology.

It is characterized by increasing at least one of the number and quality of functions to be performed.

  In this way, when the amount of reusable power consumption can be increased, the number or the quality of the functions performed by the home appliances is increased in ascending order of power consumption. It is possible to avoid a rapid decrease in power.

  (5) Moreover, in the ecosystem of the present invention, the control unit executes the home appliances in the descending order of power consumption when it is not possible to increase the consumption of the reusable power as a result of the determination. It is characterized in that at least one of the number of functions or quality is reduced.

  In this way, when the amount of reusable power consumption cannot be increased, at least one of the number or quality of functions performed by home appliances is reduced in descending order of power consumption. It is possible to reduce the speed at which the value decreases.

  Embodiments of the present invention will be described below with reference to the drawings. In the ecosystem according to the present embodiment, when the generated power of solar light or the stored power can be sufficiently supplied with solar power, for example, while improving the image quality of the liquid crystal television, the solar power Can not be supplied sufficiently, for example, by reducing the video quality of the liquid crystal television, to achieve both eco-friendliness and improved user satisfaction. Hereinafter, a liquid crystal television will be described as an example of a home appliance. However, the present invention is not limited to the liquid crystal television, and can be applied to other home appliances such as an air conditioner, an ion generator, a washing machine, and a dishwasher.

  FIG. 1 is a diagram showing an outline of an ecosystem according to the present embodiment. On the roof of the house A, there is provided a solar panel 10 that receives sunlight and generates power. The electric power generated by the solar panel 10 is stored in the storage battery 11. House A can also be supplied with grid power (commercial power) 12. Power is supplied to the power control device 2 from the solar panel 10, the storage battery 11, and the system power 12. A liquid crystal television 3 is provided inside the house A, and a power control device supplies power to the liquid crystal television 3. In the present embodiment, the power generated by the solar panel 10 is referred to as reusable power, and the power generated by a depleting resource such as oil is referred to as depleting power. If the reusable power that can be supplied changes, the liquid crystal television 3 changes the number of functions or the quality of the functions.

  FIG. 2 is a block diagram showing a schematic configuration of the ecosystem according to the present embodiment. The power control device 2 is supplied with power from three power sources. Specifically, the solar panel 10, the storage battery 11, and the system power 12. The solar panel 10 generates reusable energy such as photovoltaic power generation. Reusable energy is electric power generated without using exhaustible resources such as oil, and is sometimes called clean energy. The storage battery 11 accumulates clean energy. The system power 12 is a power source that generates power using a depleting resource such as thermal power generation and a method that affects global warming such as carbon dioxide.

  As a typical classification, it is assumed that the solar panel 10 and the storage battery 11 are 100% clean energy, and the system power 12 is 0% clean energy. However, actually, the present invention is not limited to this, and the grid power 12 may include clean energy at a certain rate. Further, for the storage battery 11, a communication line for notifying the power information transmission unit 21 of the amount of stored power and the storage speed (positive when the storage amount is increasing and negative when the storage amount is decreasing). There may be.

  The power control device 2 inputs power from three power sources (10, 11, 12) via the power input units 10a, 11a, and 12a, and supplies power to various other devices from the power output unit 22. To do. The power information transmission unit (power information output unit) 21 notifies other various devices of information indicating the ratio of power supplied from the three power sources by a predetermined means. As the predetermined means, Ethernet (registered trademark), PLC (power line communication), infrared communication, ZigBee, and other methods can be adopted.

  The liquid crystal television 3 includes a control unit 31, a video adjustment unit 32, a video output unit 33, an audio adjustment unit 34, and an audio output unit 35, and can reproduce content such as television broadcasts and DVDs. The video output unit 33 is provided with various image quality enhancement functions such as a noise reduction function, a double speed display function, a bit rate conversion function (up-converter), and a brightness adjustment function. The audio output unit 35 has a Dolby stereo function, a graphic equalizer function, a deep bass boost function, and other various sound quality enhancing functions.

  The power information receiving unit 36 (input unit) receives the power information from the power information transmitting unit 21, and the control unit 31 determines the contents of the power information and sends instructions to the video adjusting unit 32 and the audio adjusting unit 34. You can adjust the video and audio functions. The control unit 31 can also receive the power value used by the device from the power supply unit 37 in accordance with the power information.

  FIG. 3 is a flowchart showing the operation of the ecosystem according to the present embodiment. It is assumed that the power control device 2 continuously transmits power information from the power information transmission unit 21 to the power information reception unit 36. First, the main power supply of the liquid crystal television 3 is turned on (step S101). Then, the liquid crystal television 3 is activated (step S102). Next, the power information receiving unit 36 acquires the power information transmitted from the power information transmitting unit 21 (step S103).

  Here, the power information is, for example, as shown in FIG. 4, power of volatile clean energy (C1; clean energy that cannot be stored by itself, such as photovoltaic power generation), and accumulative clean energy (B1). ; Accumulated clean energy in storage battery), accumulated amount of clean energy (B2), maximum accumulated amount (B3), accumulative clean energy accumulation rate (B4; if positive, the accumulated amount increases If it is negative, it indicates that the accumulated amount is reduced), power (C2) that is clean energy in the grid power, and power (E1) that is not clean energy in the grid power is included. .

  Here, it is assumed that what proportion of the grid power is clean energy or not is set in advance, but it is also possible to take a method such as obtaining this kind of information via the Internet. . Further, the power information receiving unit 36 acquires the value of power currently used by the liquid crystal television 3 from the power supply unit 37 and passes it to the control unit 31.

  Next, the power control apparatus 2 determines the situation based on the acquired power information (step S104). FIG. 5 is a flowchart showing the determination method. First, the sign of B4 shown in FIG. 4 is determined (step S1041). If it is positive (that is, if the accumulation amount is increased), then the magnitude of B2 is set to B2 / B4 (in what time is remaining) Whether the accumulated amount is 0) and a certain threshold value X (step S1042). If it is larger than the threshold value X, it is determined that “a little more power can be consumed”; It is judged as “good”.

  In the case of “just right”, the accumulation amount increases, but of course, it does not exceed the maximum accumulation amount B3. If B4 is less than or equal to 0 in S1041 (that is, it indicates that clean energy cannot be generated sufficiently because the accumulated amount decreases), then the size of B2 is set to B2 / B4 (in what time Whether or not the amount of storage is 0) and a certain threshold Y is determined (step S1043). If the threshold Y is equal to or greater than the threshold Y, it is considered that the power can be saved using the stored power. Otherwise, it is determined that “the power consumption needs to be suppressed”. Here, another threshold value may be used to determine “just right”.

  FIG. 6 is a flowchart illustrating an example of another determination method. Compared to FIG. 5, it is assumed that the power information related to the storage clean energy is not used. Typically, there is no storage battery, but it may exist separately (C1 + C2 becomes C1 + C2 + B1). First, it is determined whether E1 shown in FIG. 4 is 0 or not (step S1141). If it is 0, the power consumption is covered only by clean energy, so it is determined that “a little more power can be consumed”. If not, next, the ratio of the usage amount of clean energy and non-clean energy is determined (step S1142). The ratio may be compared with the threshold values Z and W, and based on the result, it may be determined that “a little more power can be consumed”, “just right”, “power consumption needs to be suppressed”, or the like. Note that the determination methods shown in FIGS. 5 and 6 are both examples, and the present invention is not limited to these.

  Further, in the comparison with the threshold values X, Y, Z, and W, the time during which the accumulative clean energy can be used is used as a reference. As for each threshold value, an optimum value should be set depending on the situation. Here, if it is determined that "a little more power can be consumed", the video adjustment unit 32 and the audio adjustment unit 34 are operated to adjust the operation of the device, and the mode change process is performed to enhance the function (step S106). ). At this time, the video adjustment unit 32 instructs the video output unit 33 to display a message such as “uses clean energy effectively and activates the image quality improving circuit XX”. You may be able to be conscious.

  FIG. 7 is a flowchart showing a specific example of the process in step S106 of FIG. First, it is checked whether or not the power is off (here, power off means that the main power is on and energized but no video is displayed; the power is turned off with the remote control) (step S1060). If the power is on, the process proceeds to step S1061, and if the power is off, the process proceeds to step S1069. In step S1061, it is checked whether the noise reduction function is ON. If it is OFF, it is turned ON (step S1062). If it is ON, in step S1063, it is checked whether or not it is ON at double speed drive (creates an intermediate frame of the video, which is normally displayed at 60 Hz, and is displayed at 120 Hz or 240 Hz). If it is, it is turned on (step S1064). If it is ON, it is checked in step S1065 whether the surround sound is ON. If it is OFF, it is turned ON (step S1066). If it is ON, it is checked in step S1067 whether or not the brightness is increased. If it is in the lowered state, the brightness is increased (step S1068).

  In the case of a liquid crystal panel, the brightness UP is to improve the brightness of the backlight. For example, instead of improving the brightness of the backlight, the transmittance of the liquid crystal pixels is adjusted, and A method of increasing the contrast with the same brightness may be used. In step S1060, if the transmission is in an OFF state (however, the power is supplied and the main power source is ON), it is checked whether the standby function is ON. Here, the standby function is ON, which means that the screen is not displayed, but some functions are operating in the background. For example, the program title is received when the remote control is ON after receiving and analyzing EPG data. Or the like, or the tuner and decoder may always be moved to perform only the process of preparing the video data to be displayed so that the video can be displayed immediately when the remote control is turned on.

  The flowchart shown in FIG. 7 is arranged so that the functions are turned on in the order of relatively small increase in power consumption. However, the order is not limited to this, and any order may be used depending on the convenience of product design. Various other functions may be performed. In addition, if it is determined that “just right” in step S105 of FIG. 3, no particular action is required (step S107). If it is determined in step S105 that “the power consumption needs to be suppressed”, the video adjustment unit 32 and the audio adjustment unit 34 are operated to adjust the operation of the device, and the mode change process is performed so as to suppress the function. This is performed (step S108).

  FIG. 8 is a flowchart showing a specific example of the process in step S108 of FIG. First, in step S1080, it is checked whether the power is on. If the power is on, the process proceeds to step S1081, and if the power is off, the process proceeds to step S1089. In step S1081, it is checked whether or not the luminance can be reduced. If possible, the luminance is reduced (step S1082). Here, the brightness Down is not only the brightness Down (that is, the screen becomes darker) than the standard depending on the setting, but also the control for returning from the state in which the brightness has been increased in Step S1068 and the lowering of the backlight brightness. It also includes control that adjusts the transmittance of the liquid crystal pixels to achieve the same brightness while sacrificing the current strike.

  If the luminance cannot be reduced in step S1081, it is checked in step S1083 if the surround function is ON, and if it is ON, it is turned OFF (step S1084). Otherwise, in step S1085, it is checked whether or not the double speed drive state, and if it is ON, the double speed drive is turned OFF, or the quadruple speed drive is changed to the double speed drive (step S1086). If not, it is checked in step S1087 if the noise reduction function is ON, and if it is ON, it is turned OFF (step S1088).

  If the power supply is off in step S1080, it is checked in step S1089 whether the standby function is ON. If it is ON, some processes operating in the background are stopped.

  The table below summarizes the clean energy generation amount, judgment, and control method.

上記の表中、Ｎｏ．４において、クリーンエネルギーの発電量がほとんどない場合、夜になったと考えることが出来る。この時、響かないように、低音をカットするように音量を小さくして省エネにすることも考えられる。また、Ｎｏ．５において、ほとんど発電されていなかった状態から、発電される状態になったとき、朝になったと考えられ、電源ＯＦＦのときにもしスタンバイ機能がＯＦＦになっていなかったらＯＮにするような制御も考えられる。また、Ｎｏ．６において、Ｃ１の発電量は曇りの時には安定しないと考えられるので、ある期間で平準化した値を持って評価する方が良い場合もある。

In the table above, no. In No. 4, when there is almost no power generation amount of clean energy, it can be considered that it was night. At this time, it may be possible to save energy by reducing the volume so as to cut the bass so as not to resonate. No. 5, it was considered that it was in the morning when power was generated from a state where almost no power was generated, and when the power was off, the standby function was not turned off. Conceivable. No. In FIG. 6, since it is considered that the power generation amount of C1 is not stable when it is cloudy, it may be better to evaluate with a leveled value in a certain period.

  As described above, the liquid crystal television has been described as an example of the home appliance, but the present invention can also be applied to an air conditioner, an ion generator, a washing machine, a dishwasher, and the like. For example, a case where an air conditioner is controlled will be described. It is assumed that the surplus power of the solar panel is large or the capacity of the storage battery tends to increase. When power is not consumed, it is converted into useless heat as a result, so that it can be determined that power should be used more actively. For this reason, the air conditioner controls the wind direction louver so that the entire room can be air-conditioned. Increase wind power in some situations. On the other hand, it is assumed that the surplus power of the solar panel is small, or even if there is a storage battery, the amount of stored electricity is small and system power is used. In this case, it can be determined that grid power should be avoided as much as possible. For this reason, the air conditioner controls the wind direction louver so that only the center of the room can be air-conditioned. Reduce wind power in some situations.

  A case where the ion generator is controlled will be described. It is assumed that the surplus power of the solar panel is large or the capacity of the storage battery tends to increase. When power is not consumed, it is converted into useless heat as a result, so that it can be determined that power should be used more actively. For this reason, the ion generator increases the ion concentration and increases the air volume so that the ions can quickly reach the room. On the other hand, it is assumed that the surplus power of the solar panel is small, or even if there is a storage battery, the amount of stored electricity is small and system power is used. In this case, it can be determined that grid power should be avoided as much as possible. For this reason, an ion generator reduces an air volume.

  The case of controlling the washing machine and the dishwasher will be described. It is assumed that the surplus power of the solar panel is large or the capacity of the storage battery tends to increase. In this case, it can be determined that the timing should be as efficient as possible. For this reason, the washing machine and the dishwasher start operation when the surplus power of the solar panel is large or the capacity of the storage battery tends to increase.

  Recently, “DC Eco-House” has been proposed to which a DC power supply system combining a solar battery and a secondary battery is applied. This “DC Eco House” is a technology that contributes to the world in the environment and health business centered on energy-saving and energy-generating equipment. The current household power source is alternating current, and even if it is self-generated with solar cells, it is once converted from direct current to alternating current. On the other hand, most of the recent digital home appliances operate on direct current, and therefore convert from alternating current to direct current in the power supply circuit.

  For this reason, in power feeding from a solar cell, conversion is performed twice from direct current to alternating current and from alternating current to direct current, resulting in a large conversion loss. On the other hand, DC Eco House stores the power generated by the solar battery in the secondary battery and drives the device with direct current, so there is no conversion loss. Further, when the capacity of the secondary battery is used up, the household power supply (system power) is converted into direct current, so that the conversion is only required once. Therefore, power can be saved compared to the conventional case. The ecosystem according to the present embodiment can also be applied to a DC eco house.

  As described above, according to the ecosystem according to the present embodiment, if the ratio of the clean energy to the power consumed by the liquid crystal television is large, control is performed so as not to deteriorate the luminance, volume, and quality enhancement functions. Thus, it is possible to improve the satisfaction of the user and improve the commercial value without deteriorating the global environment. On the other hand, if the ratio of the clean energy to the power consumed by the liquid crystal television is small, the brightness, volume, and the quality enhancement function are reduced, and the liquid crystal television is controlled to operate with less energy. As a result, it is possible to greatly contribute to the protection of the global environment.
