These are figures which show the power supply circuit etc. in the said air-conditioner.

As shown in FIG. 1, the air conditioner AC1 according to the first embodiment includes, for example, a plurality of concentric slits on the front surface of a rectangular casing BD and the hot air or the cold air according to the first embodiment. An air outlet OUT is provided. The shape of each slit constituting the air outlet OUT is arbitrary, and each of the slits may be, for example, a rectangle other than the concentric shape illustrated in FIG. Inside the blowout port OUT, a blower fan (not shown in FIG. 1) to be described later and a blower motor for rotating the blower fan are provided. On the other hand, on both side surfaces of the air conditioner AC1, slit-like suction ports IN through which external air is sucked are provided.

In addition, on the rear surface of the air conditioner AC1, for example, an exhaust port B _OUT is provided which is formed of a plurality of concentric slits and exhausts unnecessary air inside the air conditioner AC1. The shape of the slit constituting the exhaust port B _OUT is also arbitrary, and each may be a rectangle in addition to the concentric shape illustrated in FIG. Inside the exhaust port B _OUT is provided with a later-described exhaust fan (not shown in FIG. 1) and an exhaust motor for rotating the exhaust fan.

  On the other hand, on the upper surface of the air conditioner AC1, an illumination unit LD including a plurality of LED light emitting elements described later is provided. The bottom surface of the air conditioner AC1 is provided with fixing legs FT at the four corners, for example. The air conditioner AC1 includes an operation unit including a switch or the like for starting the air conditioner AC1, but the installation position, configuration, and the like are arbitrary, and the description thereof is omitted in FIG.

  Next, the internal structure and operation of the air conditioner AC1 will be described with reference to FIGS. 2 and 3, the external shape described with reference to FIG. 1 is indicated by a broken line.

  As shown in a front perspective view in FIG. 2A, the illumination unit LD is provided on the top surface of the air conditioner AC1. In FIG. 2A, illustration of the blower fan and the blower motor is omitted. As shown in a top perspective view in FIG. 2B, the illumination unit LD is configured by arranging a plurality of LED light emitting elements 2 in, for example, an array. At this time, the arrangement position of the LED light emitting element 2 in the illumination unit LD is arbitrary. Further, on the inner side of the air conditioner AC1 of the illumination unit LD, it extends downward in FIG. 2A and along the bottom surface of the illumination unit LD in the depth direction in FIG. 2A (up and down direction in FIG. 2B). A heat dissipating fin is slidably movable. In FIG. 2A, the radiation fin itself is not shown, and the radiation fin will be described later with reference to FIG. In addition, a heat insulating material or the like is laid on the bottom surface of the illumination unit LD (the surface on the inner side of the air conditioner AC1) other than the movable region of the heat radiating fins, for example. With this structure, the heat from each LED light emitting element 2 in the illumination unit LD is transmitted to the inside of the air conditioner AC1 only through the heat radiation fin LAF. On the other hand, inside the air conditioner AC1, a Peltier element portion PA including a plurality of Peltier elements 4 arranged in an array, for example, is provided at a position facing the air outlet OUT. The Peltier element 4 included in the Peltier element part PA is air conditioner AC1 in a state of being sandwiched in the depth direction in FIG. 2 (a) by a hot air side fin and a cold air side fin (not shown in FIG. 2 (a)). Is supported within. The hot air side fin and the cold air side fin will also be described later with reference to FIG.

  In the above configuration, each of the suction ports IN, the blower fan, and the blower port OUT corresponds to an example of “heating means” and an example of “cooling means” according to the present invention. Moreover, the air flow path from each inlet port IN to the blower port OUT corresponds to an example of the “air flow channel” according to the present invention.

  Next, an operation during cooling and an operation during heating in the air conditioner AC1 will be described with reference to FIG.

As shown in the left side perspective view in FIG. 3A, the Peltier elements 4 constituting the Peltier element part PA are sandwiched between the hot air side fins HF and the cold air side fins CF in a lined state. In this state, the air-conditioner AC1 is supported so as to be rotatable about the horizontal rotation axis X. At this time, the hot air side fin HF is fixed so as to be in contact with the surface of the Peltier element 4 whose temperature rises due to the Peltier effect when driven. On the other hand, the cold air side fin CF is fixed so as to be in contact with the surface of the Peltier element 4 whose temperature is lowered by the Peltier effect when driven. Here, the “Peltier effect” in the present invention refers to a phenomenon in which a driving voltage applied to each Peltier element 4 is converted into a temperature difference between, for example, the front surface and the back surface of each Peltier element 4. When the air conditioner AC1 is set to perform heating based on an operation or the like in the operation unit (not shown), the Peltier element unit PA is fixed at the upright position shown in FIG. At this time, the surface of each Peltier element 4 where the temperature rises and the warm air side fin HF are in a position facing the air outlet OUT. At the same time, the upper end of the Peltier element portion PA is brought into contact with the heat dissipating fin LAF extending from the illumination portion LD toward the inside of the air conditioner AC1. At this time, the radiating fin LAF of the illuminating unit LD extends in the left-right direction in FIGS. 3A and 3B along the bottom surface of the illuminating unit LD, as indicated by the one-dot chain double arrow at the top of FIG. It is possible to move the slide. Further, the radiating fin LAF is fixed at the heating position (position shown in FIG. 3A) and the cooling position (position shown in FIG. 3B) before and after the sliding. Further, as described above, the portion other than the movable region of the radiation fin LAF on the bottom surface of the illumination unit LD has a heat insulating structure, and the heat from each LED light emitting element 2 in the illumination unit LD passes through the radiation fin LAF. Only to the inside of the air conditioner AC1. When each LED light emitting element 2 emits light in this state, the accompanying heat is dissipated downward in FIG. 3A through the radiation fin LAF at the position shown in FIG. In parallel with this, each Peltier element 4 in the Peltier element part PA has the temperature of the surface on the warm air side fin HF side (the surface facing right in FIG. 3A) due to the respective Peltier effect. Each is driven to go up. By blowing fan F _OUT air duct in OUT in this state is rotated, the air W sucked from the suction port IN of both sides as illustrated in FIG. 3 (c), from each of the LED devices 2 Are heated by the heat through the radiating fin LAF and the temperature rise of the surface of each Peltier element 4 through the warm air fin HF, and are discharged from the air outlet OUT as warm air. At this time, the temperature of the surface of each Peltier element 4 on the back side of the air conditioner AC1 (that is, the surface on the cold air side fin CF side in FIG. 3A) is lowered by the Peltier effect. The air thus discharged is discharged to the back surface of the air conditioner AC1 by the exhaust fan F _BOUT in the exhaust port B _OUT . Therefore, the temperature drop of the surface of each Peltier element 4 on the back side (cold air side fin CF side) of the air conditioner AC1 is due to the heat from the heat radiation fin LAF and the temperature rise of the surface of each Peltier element 4 via the hot air side fin HF. It does not interfere with the heating effect. In the above configuration, if light emission as the illumination unit LD is also performed in parallel, the light emission and heating by the air conditioner AC1 are performed in parallel.

On the other hand, when it is set that the air conditioner AC1 is to be cooled based on the above operation or the like, the radiation fin LAF first slides from the position shown in FIG. 3A to the right in FIG. It is fixed at the position shown in b). In parallel with this, the Peltier element PA is rotated counterclockwise from the state shown in FIG. 3A around the rotation axis X, and is fixed at the position shown in the left side perspective view in FIG. Is done. At this time, as shown in FIG. 3B, the end portion of the warm air side fin HF is in contact with the end portion of the surface opposite to the heating side of the radiating fin LAF. Further, by this rotation, the surface of each Peltier element 4 on which the temperature decreases (the surface in contact with the cold air side fin CF) and the cold air side fin CF are in a position facing the air outlet OUT. In this state, each Peltier element 4 on the Peltier element part PA has a surface facing the lower right side in FIG. ) Are driven so as to lower the temperature. By blowing fan F _OUT air duct in OUT in this state is rotated, the air W sucked from the suction port IN of both sides like the heating operation, each Peltier element via the cold air side fins CF 4 It cools by the temperature fall of the surface, and is discharged | emitted from the ventilation port OUT as cold wind (refer FIG.3 (c)). At this time, the temperature of each Peltier element 4 on the back side of the air conditioner AC1 (the hot air side fin HF side) rises due to the Peltier effect. The air warmed by the heat through the radiating fin LAF is discharged to the back surface of the air conditioner AC1 by the exhaust fan F _BOUT as in the case of heating. In addition, the portion on the right side of the cold air side fin CF in FIG. 3B in the bottom surface of the illumination unit LD has a heat insulating structure as described above. Therefore, the temperature rise of the surface of each Peltier element 4 on the hot air side fin HF side and the heat from the heat radiation fin LAF do not hinder the cooling effect due to the temperature drop on the surface of each Peltier element 4 via the cold air side fin CF. . In the above configuration, if light emission as the illumination unit LD is also performed in parallel, the light emission and the cooling by the air conditioner AC1 are performed in parallel.

Next, the electrical configuration for driving the LED light emitting element 2 and the peltier element 4 and the blower fan F _OUT, etc., will be described with reference to FIG.

As shown in FIG. 4, the air conditioner AC1 includes a power supply unit 1 connected to an external power supply. The external power source in this case corresponds to, for example, an alternating current 100 volt / 200 volt power source or an external power source such as a battery. The power supply unit 1 is not shown in FIGS. 1 to 3 for simplification of description. The power supply unit 1 includes a light emitting output unit 1L for driving the LED light emitting element 2, and the output section 1P Peltier element for driving the Peltier element 4, the blower motor M1 for rotating the blower fan F _OUT The fan motor output unit 1M1 for driving the exhaust fan and the exhaust motor output unit 1M2 for driving the exhaust motor M2 for rotating the exhaust fan F _BOUT are provided. At this time, each LED light emitting element 2 is connected in series to the light emitting output section 1L, and each Peltier element 4 is also connected in series to the Peltier element output section 1P. Each LED light-emitting element 2, each Peltier element 4, the blower motor M1, and the exhaust air motor M2 are respectively a light-emitting output unit 1L, a Peltier element output unit 1P, a blower motor output unit 1M1, and an exhaust air motor output unit. The necessary power is obtained from 1M2, and each is driven. At this time, the polarity of the voltage supplied to each Peltier element 4 is set to be the operation during heating and cooling described with reference to FIG.

  On the other hand, in addition to the above configuration, in the air conditioner AC1 according to the first embodiment, the electronic switch SW is provided between one terminal of the exhaust motor M2 and the output unit 1M2 for the exhaust motor. The motor M2 itself is connected to each Peltier element 4 in series as shown in FIG. In this electronic switch SW, the voltage at each end of each Peltier element 4 is increased to a voltage that can drive the exhaust motor M2 due to the Seebeck effect caused by the temperature of each Peltier element 4 rising due to the light emission of each LED light emitting element 2. When controlled to turn off. Here, the “Seebeck effect” is a phenomenon in which a voltage is generated in the Peltier element 4 itself when a temperature difference occurs between the front surface and the back surface.

  As described above, according to the configuration of the air conditioner AC1 according to the first embodiment and the operation at the time of cooling and heating, in the air conditioner AC1 including the illumination unit LD, from the LED light emitting element 2 of the illumination unit LD at the time of heating. The temperature of the air flowing in the air flow path is raised by heat and the temperature rise of the surface of the Peltier element part PA (each Peltier element 4) facing the air flow path, and the air is discharged outside as hot air. On the other hand, at the time of cooling, the temperature of the air flowing through the air flow path is lowered due to the temperature drop of the surface of the Peltier element part PA facing the air flow path, and the air is discharged outside as cold air. Therefore, it is possible to realize an air conditioner AC1 with efficient new lighting that is simplified, downsized, and reduced in price without using an outdoor unit or an indoor unit such as a conventional air conditioner and is unnecessary. it can. Further, since the generation of warm air during heating is supplemented by the heat from the lighting unit LD, it is possible to realize a power saving and efficient air conditioner AC1.

  Further, since the illumination unit LD is composed of a plurality of LED light emitting elements 2, an efficient air conditioner AC1 that is also used for LED illumination can be realized.

  Further, during cooling, the temperature of the Peltier element PA facing the air flow path is lowered by driving with the opposite polarity to that during heating, so that the temperature of the air flowing through the air flow path is lowered and externally supplied as cold air To release. Therefore, since the switching between the hot air and the cold air is performed electrically, the configuration of the air conditioner AC1 with illumination can be further simplified.

  Furthermore, since the Peltier element portion PA includes a plurality of Peltier elements 4, it is possible to efficiently generate hot air or cold air while downsizing the air conditioner AC1.

  Moreover, since the exhaust motor M2 covers at least a part of the driving power with the power generated in the Peltier element part PA, the air conditioner AC1 can be further downsized.

  Further, at this time, when the power generated in the Peltier element part PA exceeds a predetermined threshold, the supply of external power corresponding to the power exceeding the threshold is cut off by the electronic switch SW. Can be increased.

Furthermore, the power supply unit 1 supplies driving power necessary for each operation to each LED light emitting element 2, each Peltier element 4, the driving unit 7D, and the blower fan 8 as described later.

  Next, operation | movement of air-conditioner AC2 which concerns on 2nd Embodiment which demonstrated the structure using FIG.5 and FIG.6 is demonstrated using FIG.

  First, when air conditioning is set to be performed by the air conditioner AC2 based on an operation or the like in an operation unit (not shown), as shown in FIG. 3, the shutter 7 is moved by the drive unit 7D to a position where the inlet of the air W is closed. In parallel with this, each Peltier element 4 is driven by electric power from the power supply unit 1 to lower the temperature of the surface on the cold air passage 5 side. As a result, the air W that has been discharged from the blower fan 8 and entered the cold air passage 5 as wind is temporarily moved through the side walls 5W by the Peltier elements 4 arranged in the moving direction along with the movement. It is lowered and discharged as cold air from the outlet of the cold air passage 5 (the outlet in the right direction in FIGS. 5 and 7). At the time of cooling, each LED light emitting element 2 is driven, and thus light emission from the illumination unit LD is also performed. With the above operation, the light emission from the illumination unit LD and the cooling by the air conditioner AC2 are executed in parallel.

  Next, when it is set to perform heating by the air conditioner AC2 based on the operation in the operation unit, as shown in FIG. 7 (b), air W is released from the blower fan 8 as wind, The shutter 7 is moved by the driving unit 7D to a position where the inlet of the air W in the path 5 is blocked. In parallel with this, each Peltier element 4 is driven by electric power from the power supply unit 1 and raises the temperature of the surface on the warm air passage 3 side. In parallel with these, each LED light emitting element 2 is also driven, and light emission from the illumination unit LD is also performed. At this time, each LED light emitting element 2 is generating the heat | fever of the quantity corresponding to the said drive similarly to the case of 1st Embodiment. And by these, the air W which was discharged | emitted from the ventilation fan 8 and entered into the warm air path 3 is a side wall by each of the Peltier device 4 and each LED light emitting element 2 which were arranged in the moving direction with the movement. The temperature is raised for a while via 3W, and is discharged as warm air from the exit of the warm air passage 3 (the right exit in FIGS. 5 and 7). With the above operation, light emission from the illumination unit LD and heating by the air conditioner AC2 are executed in parallel.

Here, as shown in FIG. 8, the power supply unit 1 according to the second embodiment includes the light emission output unit 1L and the Peltier element output unit 1P similar to the power supply unit 1 according to the first embodiment. A blower motor output unit 1M1 for driving a blower motor M for rotating the blower fan 8 is provided. In FIG. 8, of the configuration of the air conditioner AC <b> 2 illustrated in FIGS. 5 to 7, configurations other than the LED light emitting elements 2, the warm air passages 3, and the Peltier elements 4 are not illustrated. The air conditioner AC2 according to the second embodiment does not include the exhaust fan F _BOUT and the exhaust motor M2 in the air conditioner AC1 according to the first embodiment, and thus the exhaust motor output unit 1M2 is unnecessary. On the other hand, since the said ventilation fan 8 which concerns on 2nd Embodiment discharge | releases the air W which becomes the origin of a warm air and cold air, it is calculated | required that it is powerful, realizing energy saving. Therefore, in the air conditioner AC2 according to the second embodiment, each Peltier element 4 is generated by the Seebeck effect due to the heat from each LED light emitting element 2 that is driven with the hot air passage 3 sandwiched both during cooling and during heating. The generated power is configured to be a part of the driving power of the motor M for rotating the blower fan 8. That is, as shown in FIG. 8, each Peltier element 4 is connected in series with a blower motor M, and electric power due to the Seebeck effect is taken out and supplied to the blower motor M. And the electronic switch SW similar to air conditioner AC1 which concerns on 1st Embodiment is provided between the one terminal of the ventilation motor M, and the output part 1M1 for ventilation motors. At this time, in the electronic switch SW according to the second embodiment, due to the Seebeck effect caused by the temperature of each Peltier element 4 rising due to the light emission of each LED light-emitting element 2, the voltage at both ends of each Peltier element 4 causes the blower motor M to move. It is controlled to be turned off when it rises to a drivable voltage.

  As described above, according to the configuration of the air conditioner AC2 according to the second embodiment and the operation at the time of cooling and heating, in addition to the effects of the configuration of the air conditioner AC1 according to the first embodiment and the operation at the time of cooling and heating, The temperature of the air W flowing through the warm air path 3 through the side wall 3W is increased by the heat from the illumination unit LD and the temperature rise of the surface of the Peltier element part PA facing the warm air path 3, and the exit is taken as warm air. To the outside. Further, at the time of cooling, the temperature of the air W flowing through the cold air passage 5 is lowered through the side wall 5W due to the temperature drop of the surface of the Peltier element part PA facing the cold air passage 5, and is discharged to the outside as the cold air. Therefore, it is possible to distinguish between the hot air passage 3 and the cold air passage 5 and perform heating and cooling more efficiently. That is, as illustrated in FIG. 9, the air conditioner AC2 according to the second embodiment is installed on the ceiling of the house H with the illumination unit LD facing down, thereby eliminating the need for the outdoor unit and the indoor unit. AC2 can be realized. At this time, particularly for efficiency, since heating from each LED light-emitting element 2 and temperature rise by each Peltier element 4 are used in combination during heating where high output is required, the drive power can be reduced efficiently and significantly. Heating with reduced power consumption is possible.

  In addition, since the shutter unit 7S that opens the inlet of the hot air passage 3 and closes the inlet of the cold air passage 5 and the blower fan 8 that flows the air W through the opened hot air passage 3 during heating are provided. The heating function can be realized by the configuration.

  Further, since the shutter portion 7S that opens the inlet of the cold air passage 5 and closes the inlet of the hot air passage 3 and the blower fan 8 that flows the air W through the opened cold air passage 5 at the time of cooling are provided. The cooling function can be realized.

  In the second embodiment described above, the entry of the air W into the hot air passage 3 and the cold air passage 5 is mechanically switched by the operation of the shutter portion 7S. However, in addition to this, the warm air path 3 and the side wall including the side wall 3W are centered on the direction of discharge of the air W from the blower fan 8 and the rotation axis parallel to the longitudinal center axis of each of the warm air path 3 and the cool air path 5. By rotating the entire cold air passage 5 including 5 W as a unit, the entry of the air W into the hot air passage 3 and the cold air passage 5 may be mechanically switched without using the shutter portion 7S.

  Further, in the first and second embodiments described above, the configuration including a plurality of LED light-emitting elements 2 and a plurality of Peltier elements 4 has been described, but one of each may be provided.
