Best mode of implementing the invention

The embodiments of the present invention will be described below with reference to the drawings.

The air conditioner is generally constituted by an outdoor unit and an indoor unit that are connected to each other by a refrigerant pipe. Figs. 1 and 2 show an indoor unit of the air conditioner of the present invention.

As shown in Fig. 1 and Fig. 2, the indoor unit has the suction port 2a and the upper suction port 2b as suction ports for taking in indoor air into the main body 2. The front suction port 2a has a movable front panel that can be opened and closed freely (hereinafter only When the front panel 4 is closed, the front panel 4 is in close contact with the main body 2 and the front suction port 2a is closed. When the air conditioner is in operation, the front panel 4 is moved in a direction separating from the main body 2 to open the front. Suction port 2a.

The inside of the main body 2 includes a prefilter 5 disposed on the downstream side of the front suction port 2a and the upper suction port 2b for removing dust contained in the air, and is disposed on the downstream side of the prefilter 5 for use with the front side. The suction port 2a and the upper suction port 2b receive a heat exchanger 6 for exchanging indoor air heat, an indoor fan 8 for transporting air exchanged by the heat exchanger 6, and an air for blowing air from the chamber inlet fan 8 to the room. The blowing air outlet 19 is opened and closed, and the upper and lower blades 12 that change the air blowing direction up and down, and the upper and lower blades 14 that change the air blowing direction to the left and right. Moreover, the upper portion of the front panel 4 is coupled to the upper portion of the main body 2 through a plurality of arms (not shown) provided at both ends thereof to drive and control a driving motor coupled to one arm of the plurality of arms (not shown) In the state in which the air conditioner is continuously rotated, the front panel 4 is moved forward from the position at which the air conditioner is stopped (the closed position of the front suction port 2a). Similarly, the upper and lower blades 12 are connected to the lower portion of the main body 2 through a plurality of arms (not shown) provided at both ends thereof.

Moreover, the ventilation fan unit 16 for exchanging indoor air is provided at one end of the indoor unit (the left end portion is viewed from the front of the indoor unit, and is on the bypass flow path 22 side of the partition 46c to be described later). The rear side of the ventilation fan unit 16 is provided with an electrostatic atomizing device 18 for generating an electrostatic mist and having an air purifying function for purifying indoor air.

Further, Fig. 1 shows a state in which the body cover (not shown) for covering the front panel 4 and the main body 2 is removed, and Fig. 2 is a view for explaining the connection position between the indoor unit body 2 and the electrostatic atomizing device 18, The state in which the electrostatic atomization device 18 housed in the inside of the main body 2 is separated from the main body 2 is shown. The electrostatic atomizing device 18 is actually in the shape shown in Fig. 3, and is attached to the left side portion of the main body 2 as shown in Fig. 1 or Fig. 4 .

As shown in FIG. 2 to FIG. 4, the electrostatic atomization device is provided in the main flow path 20 that communicates with the air outlet 10 through the heat exchanger 6, the indoor fan 8, and the like from the front suction port 12a and the upper suction port 2b. In the middle of the bypass flow path 22 bypassing the heat exchanger 6 and the indoor fan 8, a high-pressure transmitter 24 and a bypass blower fan 26 constituting a high-voltage power source are disposed on the upstream side of the bypass flow path 22, and An electrostatic atomizing unit 30 and a muffler 32 having a heat radiating portion 28 that promotes heat dissipation of the electrostatic atomizing device 30 are disposed on the downstream side of the bypass flow path 22. Therefore, the housing 34 which is a part of the bypass flow path 22 is housed in the state in which the high pressure conveyor 24, the bypass blower fan 26, the heat radiating portion 28, the electrostatic atomizing unit 30, and the muffler 32 are disposed in this order from the upstream side. . By accommodating the casing 34 and improving the assemblability, the flow path can be formed in the casing 34, so that space saving can be achieved, and the air flow constituted by the bypass blower fan 26 can surely touch the high voltage of the trigger heat portion. The device 24 and the heat radiating portion 28 can cool the heat radiating portion 28, and can reliably introduce the electrostatic mist generated from the electrostatic atomizing device 30 into the air outlet 10 of the air conditioner, and discharge the generated static mist into the air-conditioned room.

Further, the casing 34 is viewed from the front surface of the indoor unit main body 2 so as to be arranged in a direction in which the air flow in the inside of the casing 34 is parallel to the longitudinal direction of the air flow flowing through the main flow path 20, whereby When viewed from the front of the indoor unit body 2, it can be disposed adjacent to the position overlapping with the ventilation fan unit 16, and space saving can be achieved.

Further, the high voltage transmitter 24 does not have to be housed in the casing 34. However, it is preferably housed in the casing 34 in order to suppress the temperature rise or space saving by the ventilation of the bypass passage. Inside.

A well-known electrostatic atomizing unit 30 will be described with reference to FIGS. 5 and 6.

As shown in Fig. 5, the electrostatic atomizing unit 30 is a heat dissipating portion (for example, a heat radiating fan) that is thermally adhered to and connected to the heat dissipating surface 36a by a plurality of Peltier elements 36 having a heat dissipating surface 26a and a cooling surface 36b. 28. The discharge electrode 38 which is thermally and closely adhered to the cooling surface 36a and which is electrically connected to the discharge electrode 36 is disposed through the electrically insulating material (not shown), and the counter electrode 40 is disposed at a predetermined distance from the discharge electrode 38.

Further, as shown in Fig. 6, the control unit 42 (refer to Fig. 1) disposed in the vicinity of the ventilation fan unit 16 is connected to the Peltier drive power source 44 and the high voltage transmitter 24, and the Peltier element 36 is electrically connected. The Peltier drive power source 44 is connected, and on the other hand, the discharge electrode 38 and the counter electrode 40 are electrically connected to the high voltage transmitter 24.

Further, in the electrostatic atomizing device 30, the counter electrode 40 may not be provided in order to generate electrostatic mist from the discharge electrode 38 at a high voltage discharge. For example, when one of the terminals of the high-voltage power source is connected to the discharge electrode 38 and the other terminal is connected to the frame, the portion adjacent to the discharge electrode 38 of the frame connection structure and the discharge electrode 38 are discharged. With such a configuration, the configuration in which the frame is connected can be regarded as the counter electrode 40.

In the electrostatic atomizing device 30 of the above configuration, when the controller 42 controls the Peltier driving power source 44 to flow a current to the Peltier element 36, heat is transferred from the cooling surface 36 to the heat radiating surface 36a to discharge the electrode 38. The state in which the temperature is lowered is dew condensation at the discharge electrode 38. When the high voltage conversion unit 24 is controlled by the control unit 42 to apply a high voltage to the discharge electrode 38 to which dew condensation water has adhered, a discharge phenomenon occurs in the dew condensation water to generate an electrostatic mist having a particle diameter of a nanometer size. Further, in the present embodiment, since the negative high voltage power source is used as the high voltage converting portion 24, the electrostatic mist is negatively charged.

Further, in the present embodiment, as shown in Fig. 7, the main channel 20 has the rear wall portion 46a constituting the frame 46 of the main body 2 and the two side walls extending forward from both end portions of the rear wall portion 46a (the 7 shows only the left side wall 46b, the rear side wall 48a of the guide member (air supply guide) 48 formed on the lower side of the frame 46, and the two side walls extending forward from both end portions of the rear wall 48a (7th) Only the left side wall 48b is shown in the drawing, and one side wall (left side wall) 46b of the frame 46 and one side wall (left side wall) 48b of the rear guide member 48 constitute a partition wall separating the bypass flow path 22 from the main flow path 20. 46c. Further, the side wall 46b of the frame 46 forms the bypass suction port 22a of the bypass flow path 22, and on the other hand, the side wall 48b of the rear guide member 48 forms the bypass air outlet 22b of the bypass flow path 22.

When the air conditioner is in cold air, the relative humidity of the low temperature air passing through the heat exchanger 6 of the indoor unit is high, and in the case where the electrostatic atomizing device 18 is provided with the Peltier element 36 for replenishing moisture, not only the Peltier The pin-shaped discharge electrode 38 of the element 36 is susceptible to condensation on the entire Peltier element 36. On the other hand, in the heating, since the high temperature air relative humidity of the heat exchanger 6 of the indoor unit is low, there is a high possibility that the discharge electrode 38 of the Peltier element 36 does not condense.

According to the above configuration, the main flow path 20 and the bypass flow path 22 are separated by the partition wall 46c, and the electrostatic atomization device 18 for generating electrostatic mist is provided in the bypass flow path 22, and the temperature and humidity are not adjusted without passing through the heat exchanger 6. The air can be supplied to the electrostatically atomizing device 18. In this way, it is possible to effectively prevent condensation of the entire Peltier element 36 of the electrostatic atomizing device 30 in the cold air, thereby improving safety. Moreover, it is possible to reliably generate electrostatic mist during heating.

The bypass flow path 22 is constituted by the bypass suction pipe 22c, the casing 34, and the bypass blow pipe 22d, and one end is connected to the bypass suction pipe 22c formed on the bypass suction port 22a of the frame side wall 46b to the left side (with The left side wall 46b is approximately orthogonal to the front panel 4, and the other end is connected to one end of the housing 34, and the bypass blowing tube 22d, which is connected to the other end of the housing 34 at one end, extends downward and bends to the right. The other end is connected to the bypass air outlet 22b of the side wall 48b of the rear guiding member 48. In such a manner that the casing 34 constitutes a part of the bypass flow path 22, space saving can be achieved, and the series of structures are passed through the bypass blowing pipe 22d to reliably discharge the electrostatic mist from the electrostatic atomizing device 18 to the main flow path. 20 induction, and the electrostatic mist can be released into the air-conditioned room.

The bypass suction port 22a is located between the prefilter 5 and the heat exchanger 6, that is, on the upstream side of the prefilter 5 and on the heat exchanger 6, and the dust contained in the air taken in from the front suction port 2a and the upper suction port 2b. The prefilter 5 can be effectively removed, so that the dust can be prevented from entering the electrostatic atomizing device 18. Thereby, it is possible to effectively prevent dust from accumulating in the electrostatic atomizing device 30, and it is possible to stably discharge the electrostatic mist.

In this embodiment, although the prefilter 5 has both the electrostatic atomizing device 18 and the prefilter of the main flow path 20, it is only necessary to clean the prefilter 5 in maintenance, and it is not necessary to separately perform the sweeping. Therefore, the maintenance can be simplified. Further, in the air conditioner having the pre-filter automatic cleaning device which will be described later, it is not necessary to perform special maintenance on the prefilter 5, and maintenance-free cleaning can be realized.

On the other hand, the bypass air outlet 22b is located on the downstream side of the heat exchanger 6 and the indoor fan 8, and is located in the vicinity of the air outlet 10, and the electrostatic mist that is discharged from the bypass air outlet 22b is diffused by the air flow of the main flow path 20. And filled the whole room. The reason why the bypass air outlet 22b is provided on the downstream side of the heat exchanger 6 is that, since it is provided on the upstream side of the heat exchanger 6, since the heat exchanger 6 is made of metal, most of the electrostatic mist of the charged particles is generated. (about 8 to 90% or more) will be absorbed by the heat exchanger 6. The reason why the bypass air outlet 22b is provided on the downstream side of the indoor fan 8 is that once it is installed on the upstream side of the indoor fan 8, since there is a turbulent flow inside the indoor fan 8, the air passing through the inside of the indoor fan 8 is in the impact chamber. During the process of each part of the fan 8, a part of the electrostatic mist (about 50% or so) is absorbed.

Further, after the bypass air outlet 22b is provided, the main flow path 20 side of the side wall 48b of the guide member 48 is provided, and the indoor fan 8 applies a predetermined speed to the air flow, and is disposed on the side of the main flow path 20 of the side wall 48b. Pressure is generated on the side of the flow path 22, and a negative pressure portion having a low pressure is formed oppositely to the side of the main flow path 20 with respect to the bypass flow path 22, and air is induced from the bypass flow path 22 toward the main flow path 20. Therefore, the bypass blower fan 26 may be of a small capacity, and the bypass blower fan 26 may not be provided as the case may be.

Further, the bypass blow-off pipe 22d is connected to the junction point (the bypass air outlet 22b) of the main flow path 20 to connect the partition wall 46c (the side wall 48b of the rear guide member 48) to be oriented orthogonally to the air flow in the main flow path 20. direction. This is because the electrostatic atomizing device 30 generates an electrostatic mist by the discharge phenomenon as described above, and is inevitably accompanied by the discharge sound and has directivity to the discharge sound. Therefore, in the state where the bypass flow pipe 22d is connected to the main flow path 20 (the bypass air outlet 22b), the bypass flow path 22 is connected in parallel to the front panel 4, and is in front of the indoor unit or obliquely forward. People, the discharge sound is extremely non-directional and can reduce noise.

Further, as shown in Fig. 8, the bypass blowing pipe 22d is inclined at a junction with the main flow path 20 with respect to the partition wall, and is connected to the upstream side with respect to the air flow in the main flow path 20, thereby further reducing the discharge sound. The noise has an effect.

In the case where the direction in which the bypass blowing pipe 22d is directed is directed to the downstream direction of the air flow in the main flow path 20, if the extension line is not previously extended from the air outlet 10 to the outside, it is generated. The discharge sound is directly emitted from the air outlet 10 to the outside, and the amount of the direct discharge into the user's ear is small, so that the noise reduction effect can be achieved.

As described above, the main flow path 20 and the bypass flow path 22 are separated by the partition wall 46c, and the electrostatic atomization device 18 for generating electrostatic mist is provided in the bypass flow that bypasses the heat exchanger 6 and communicates with the main flow path 20. Since the air 22 is supplied to the electrostatic atomizing device 18 without passing through the heat exchanger 6, the entire Pare member 36 of the electrostatic atomizing unit 30 can be effectively prevented from being opened when the cold air is blown. Condensation is generated to improve safety, and when the heating is turned on, electrostatic mist can be surely generated, and static electricity mist can be stably generated regardless of the operation mode of the air conditioner, that is, regardless of the season.

Next, an air conditioner in which a pre-filter automatic cleaning device that sucks and removes the suction device attached to the dust of the prefilter 5 is further provided will be described. When the ventilation fan unit 16 is described with reference to Fig. 9, the ventilation fan unit 16 may be dedicated to ventilation, or may be a gas supply device having a suction device provided in an indoor unit having a prefilter automatic cleaning device. The ventilation fan unit 16 shown in Fig. 9 is attached to the suction device 58 of the prefilter automatic cleaning device on the bypass passage 46 side of the partition 46c. However, since the prefilter automatic cleaning device is well known, one side is known. A brief description will be given with reference to Fig. 10. The detailed structure and operation method of the prefilter automatic cleaning device are not particularly limited.

As shown in Fig. 10, the prefilter automatic cleaning device 50 has a suction nozzle 52 which is slidable along the surface of the prefilter 5, and the suction nozzle 52 is provided by a pair of guide rails 54 disposed at the lower end of the prefilter 5. The prefilter 5 maintains a very narrow gap and can smoothly move left and right, and the dust adhering to the prefilter 5 is sucked and removed by the suction nozzle 52. Further, one end of the freely bendable suction pipe 56 is coupled to the suction nozzle 52, and the other end of the suction pipe 56 is coupled to the suction device 58 whose suction amount can be changed, and the exhaust pipe 60 is coupled to the suction device 58 and is led to the outside.

Further, a belt (not shown) that is slidable along the suction nozzle 52 is wound around the upper and lower sides of the suction nozzle 52, and is formed on the surface opposite to the prefilter 5 of the suction nozzle 52. The pre-filter 5 has a slit-shaped nozzle opening having an approximately equal length, and on the other hand, a slit-shaped suction hole having a length of, for example, 1/4 of the length of the prefilter 5 is formed in the belt.

The pre-filter automatic cleaning device 50 of the above configuration can sequentially clean the cleaning ranges A, B, C, and D of the pre-filter 5 as needed, and when the cleaning range A is sucked, the driving belt is driven and the suction hole is fixed to the range A position. The suction nozzle 52 is driven from the right end of the prefilter 5 to the left end while sucking, and the range A of the cleaning prefilter 5 in the horizontal direction is sucked.

Next, the driving belt is fixed to the range B position, and the suction nozzle 52 is driven from the left end to the right end of the prefilter 5 while sucking in this state, which is the range B in the horizontal direction of the cleaning prefilter 5. Similarly, the range C and D of the cleaning prefilter 5 can be sucked up.

The dust adhering to the prefilter 5 and sucked up by the suction nozzle 52 is discharged to the outside through the suction pipe 56, the suction device 58, and the exhaust pipe 60.

Referring to Fig. 9, an opening 62 is formed in the suction path of the suction device 58, and a damper 64 for opening and closing the opening 62 is provided. The ventilation fan unit 16 serves as a ventilation device when the damper 64 opens the opening 62. When the suction cleaning is performed, the opening is closed by the damper 64 to absorb the dust from the suction hole of the belt. That is, the suction and the ventilating function can be realized by using the same suction device 58.

Further, in FIG. 9, the exhaust pipe 60 is not shown in the drawings, but the exhaust pipe 60 is connected to the exhaust port 58a of the suction device 58.

Fig. 11 shows an electrostatic atomization device 18A having no casing 34. The electrostatic atomization device 18A is assembled in the indoor unit body 2 as shown in Fig. 12. Alternatively, it is assembled in the broken line region 18B shown in Fig. 12 (in the electrostatic atomization device shown in Fig. 9, the electrostatic atomization device 30 and the muffler 32 provided on the downstream side of the bypass flow path 22 are about In the same position). The electrostatic atomizing device 18A is disposed at a position overlapping the ventilation fan unit 16 and is disposed in the opening portion 62 of the ventilation fan unit 16 and the electrostatic atomizing device 18A is disposed on the front side or the upper surface of the indoor unit. The vicinity of the damper 64 is disposed in a portion where the suction air by the ventilation fan unit 16 flows.

More specifically, the electrostatic atomizing device 18A of Fig. 11 is an electrostatic atomizing unit 30 having a heat dissipating portion 28 and is integrally mounted with the muffler 32, except that the electrostatic atomizing unit 30 portion of the heat dissipating portion 28 and the muffler 32 are housed in separate portions. The casing (the unit casing 66 and the muffler casing 68) is connected to one side of the bypass blow pipe 22d and communicates with the muffler casing 68, and the other side of the bypass blow pipe 22d is connected and communicates with the main flow path 20. In this case, the partition portion 46c is separated from the main flow path 20, and is disposed between the left side surface of the body cover not shown in the drawing, and is provided with a ventilating fan unit 16, an electrostatic atomizing device 18A, and the like. 22e replaces the aforementioned bypass suction pipe 22c and the casing 34, and accommodates the bypass blow pipe 22d to constitute the bypass flow path 22.

Further, the case where the bypass blow-off pipe 22d reaches the noise direction with respect to the direction in which the air flow of the main flow path 20 is directed is as described above, but it is not necessary, and the muffler housing 68 may be directly connected to the side. The outlet 22b is blown. As a result, the configuration of the electrostatic atomization device 18A can be simplified. However, in order to reduce the noise, it is necessary to consider the direction as the bypass blowout pipe 22d.

As a result, the air sucked into the main body 2 through the prefilter 5 is sucked into the accommodating portion 22e from the bypass suction port 22a on the downstream side of the prefilter 5, and the direction of the air flow is viewed from the front side of the indoor unit body 2, The direction of the air flow flowing through the main flow path 20 flows in parallel in the accommodating portion 22e. The heat radiating portion 28 is cooled by the air flowing in the accommodating portion 22e in this manner, and is taken into the electrostatic atomizing unit 30 from the opening portion (not shown) formed in the unit casing 66.

With such a configuration, the space around the ventilation fan unit 16 overlapping the ventilation fan unit 16 on the front or the upper surface of the indoor unit constitutes a bypass flow path, and the electrostatic atomization device 18A of the ventilation fan unit 16 can be effectively utilized. The storage unit 22e is equal to the space saving. In addition, in this configuration, the high voltage transmitter 24 is disposed in any portion of the accommodating portion 22e such as the ventilating fan unit 16 and the electrostatic atomizing device 18A, and the bypass air blowing fan 26 is not provided.

Further, the indoor unit body 2 is viewed from the front side so that the bypass flow path 22 is configured to flow in parallel with the air flow passing through the main flow path 20, and as described above, the main flow path can be realized by the simple structure of the partition wall 46c. Since the bypass flow path 22 is branched, the number of components can be reduced by easily forming the bypass flow path 22.

Further, in a state in which the structure is constructed, the prefilter of the electrostatic atomizing device 18A and the prefilter of the main channel 20 can be shared by the prefilter 5. The effect of the sharing is as described above, and thus the detailed description thereof will be omitted.

Further, an opening 46d may be formed in the vicinity of the lower portion of the frame 46 provided at the rear portion of the ventilation fan unit 16 to pull out the piping (not shown) connecting the indoor unit and the outdoor unit. The bypass suction port 22a is formed in the opening of the accommodating portion 22e of the partition wall 46c (the frame side wall 46b) by sucking air into the accommodating portion 22e, and is communicated with the outside of the indoor unit through the prefilter 5, but is formed. The opening 46d at the lower portion of the frame 46 constitutes an opening in which the accommodating portion 22e is directly connected to the outside of the indoor unit to take in the surrounding air. In such a configuration, the accommodating portion 22e constitutes a bypass flow path that bypasses the prefilter 5. Therefore, the air constituting the suctioned electrostatic atomizing device 18A flows into the opening 46d without passing through the prefilter 5. Therefore, a prefilter for the electrostatic atomizing device 18A may be separately provided as needed. Further, even in the structure in which the opening 46d is formed, the electrostatic atomizing device 18A is disposed at a position overlapping the ventilation fan unit 16 as viewed from the front or the upper surface of the indoor unit, and the accommodating portion 22e can be effectively utilized to save the structure. The same is true for spatialization.

As described above, on the side of the main flow path 20 of the bypass suction port 22b, the indoor fan 8 gives a pressure difference to the air flow in a state of a predetermined speed, and constitutes a temptation. Therefore, even if the bypass blower fan 26 is not provided, the heat radiating portion 28 can be cooled by the air induced from the accommodating portion 22e of the bypass flow path toward the main passage 20 through the bypass blow pipe 22d. The electrostatic mist generated by the electrostatic atomizing unit 20 is induced to the main flow path 20 and can be discharged into the air-conditioned room. Further, the heat radiating portion 28 is disposed in the vicinity of the opening portion 62 and the damper 64 in the vicinity of the opening portion 62 and the damper 64, and is disposed in a portion where the air sucked into the opening portion 62 flows. Therefore, the heat radiating portion 28 can be cooled by the air taken in by the ventilation fan unit 16.

Further, as shown in Fig. 12, the heat radiating portion 28 of the electrostatic atomizing device 18A is provided close to the opening portion 62 of the suction device 58, and the heat radiating portion 28 can be further cooled by the air sucked into the opening portion 62. The heat dissipation from the electrostatic atomizing unit 30 is promoted. Further, in the case where the fan dedicated to ventilation is used as the ventilation fan unit 16, since the damper 64 is not provided, the heat dissipating portion 28 can be disposed closer to the suction port of the ventilation fan unit 16 to more efficiently The heat radiating portion 28 is cooled.

As described above, according to the above configuration, the main flow path 20 and the accommodating portion 22e constituting the bypass flow path are separated by the partition wall 46c, and the electrostatic atomization device 18A for generating electrostatic mist is provided in the accommodating portion 22e, so that heat exchange is not performed. The air of the unregulated temperature and humidity of the device 6 can be supplied to the electrostatic atomizing device 18A. Therefore, under cold air, the condensation of the Peltier element 36 of the electrostatic atomizing device 30 can be effectively prevented, thereby improving safety. Moreover, under the heating, the electrostatic mist can be surely generated, and the operation mode of the air conditioner is irrelevant, that is, the static mist can be stably generated irrespective of the season.
