The present invention is installed in a ductless manner, or installed to have a single duct line communicating with the indoor and outdoor, the exhaust cycle to suck the indoor air to the outside and the air supply to suck the outdoor air to the indoor The present invention relates to an air conditioner capable of controlling a cycle.

Conventionally, the air conditioner 100 shown in FIG. 1 has been used as a device capable of ventilating while recovering energy contained in air introduced into or discharged from a room. The air conditioner 100 has an exhaust inlet 180 for introducing indoor air at one side of a case of a predetermined shape and an outside air outlet 170 for delivering outdoor air to the indoor, and the other side of the case. The outside air inlet 150 for introducing outdoor air and the exhaust outlet 160 for discharging the indoor air to the outside is formed, the inner space of the case is divided into four spaces by the partition wall, The heat exchanger 110 for heat exchange between the indoor air discharged to the outside and the air introduced from the outside is provided at the center portion of the case where the partition walls cross, and the exhaust fan 120 and the air supply fan 130 are provided, respectively.

As shown in FIGS. 1B and 2, the air conditioner 100 is installed at one side of the ceiling formed in the upper part of the building, and the exhaust inlet 180 of the air conditioner 100 is configured to exhaust air to the outside. It is connected to the exhaust duct 30, which is a distribution path, and the exhaust duct 30 is installed in communication with the exhaust port 10 installed in the ceiling of each of the rooms 1, 2, 3, and 4. On the other hand, the outside air outlet 170 of the air conditioner 100 is connected to the air supply duct 40, which is a distribution path of air flowing into the room, the air supply duct 40 is each indoor (1, 2, 3, 4) is installed in a structure in communication with the air supply port 20 installed in the ceiling. That is, the exhaust inlet 180 and the outside air outlet 170 of the air conditioner 100 are connected to the indoor space by the exhaust duct 30 and the air supply duct 40 and the outside air of the air conditioner 100. The inlet 150 and the exhaust outlet 160 are also connected to the outdoor space through the air supply duct 30a and the exhaust duct 40a, respectively. In the related art, the air conditioner 100, the exhaust duct 30, and the air supply duct 40 are configured as a single ventilation system, so that when the external air is introduced and the path for discharging the indoor air is different from each other. There was no.

 However, the conventional ventilation system using the air conditioner 100 is too large in size and requires the configuration of a complicated exhaust duct 30 and an air supply duct 40, and the exhaust duct 30 and the air supply duct 40 There was a problem that the ceiling must be secured above a certain height in order to install. And, if you do not want the heat recovery function of the air conditioner 100 and only want to simply vent, the bypass passage to the air conditioner 100 in order to introduce the outside air into the room without passing through the air conditioner 100 It was forced to take a complicated configuration such as forming a. In addition, the air conditioner 100 has a problem that the maintenance is difficult even though the device price is quite expensive.

Therefore, the present inventors can directly install on the side wall of the building without the need for a complicated duct installed on the ceiling, and absorbs the heat and humidity of the air intake and exhaust in a compact air conditioner that is easy to maintain or In addition to absorbing or releasing the heat and humidity of air using charcoal to emit, AC-type air conditioners (200a, 200b) were developed and applied for utility model registration and patent application. : 10-0549206, 20-0375800)

The word "AC" is named after paying attention to the characteristics of the air conditioner in which the air direction changes with time and ventilation is performed like AC electricity. The utility model registered AC-type air conditioner (200a, 200b) is a hollow cylinder, as shown in Figure 3, the intake and exhaust vents 211, 212 are formed on both sides of the longitudinal direction, respectively, one side is indoor It is arranged to communicate with the other side and the housing 210 is arranged to be in communication with the outside, and a filter manufactured by stacking the plate manufactured by using charcoal in multiple stages at a predetermined interval, one or more are installed in the interior of the housing 210 Heat / moisture exchange means 240 for absorbing heat and moisture of the air flowing through the housing or releasing the absorbed heat and moisture, and to suck air from the outside to the inside of the housing 210 and discharge it to the indoor side; A first fan 220 disposed therein, a second fan 230 disposed to suck air from the inside of the housing 210 to the outside, and a second fan 230 disposed at the outside of the housing 210; 1 temperature The temperature difference is calculated by receiving a stand 250, a second temperature sensor (not shown) to be installed indoors, and output values of the first temperature sensor and the second temperature sensor, and when the temperature difference is within a predetermined temperature difference range, It is characterized in that it comprises a control unit (not shown) for operating the first fan 220 and the second fan 230 alternately for a predetermined time.

The AC type air conditioners 200a and 200b configured as described above are particularly useful for buildings with low ceiling heights because they do not require large installation spaces, and can be constructed with only one duct line or without ductwork. And, the life of the heat / moisture exchange means 240 consisting of a charcoal plate has an advantage such as a very long and the cycle of cleaning, etc. is greatly increased than the conventional. However, the air conditioner has the same path in which indoor air and outdoor air move within the housing 210. That is, outdoor air is introduced into the room through the operation of the first fan 220 through the second fan 230, and indoor air is discharged to the outside through the operation of the second fan 230 through the first fan 220. Therefore, a pressure loss occurs while passing through the first fan 220 or the second fan 230 which does not operate in the flow of air, and thus it is difficult to obtain a high air volume.

The present invention is to solve the above problems, it is possible to change the wind direction only by driving a single fan to enable the air supply and exhaust, does not require a large installation space, the blower and air advantageous to secure high air volume It is an object to provide a conditioner.

It is installed in a ductless manner or installed to have a single duct line communicating indoors and outdoors, and controls an exhaust cycle that sucks indoor air and discharges it to the outside, and an air supply cycle that sucks outdoor air and discharges it into the room. In the air conditioner that can be, as a hollow cylinder, the front and rear ends of the housing is formed with a vent; A fan casing installed inside the housing, an exhaust port formed at a side thereof, and an inlet formed at an upper surface thereof; A centrifugal blowing fan mounted inside the fan casing and operated by a fan driving motor; A fan casing driving motor for rotating the pan casing clockwise or counterclockwise with respect to the pan casing central axis; And a controller configured to adjust a driving direction of the fan casing driving motor under a specific condition. It provides a wind direction conversion air conditioner, characterized in that configured to include.

Figure 5 is an exploded perspective view of the main part of the wind direction conversion air conditioner according to the present invention. 6 is a detailed view of the pan casing. 7 is an embodiment of a heat exchanger according to the present invention. 8 is a detailed view of a heat exchange part support block and a heat storage plate. 9 is a schematic diagram showing the flow of air during exhaust and air supply using the air conditioner.

Hereinafter, the present invention will be described in detail with reference to the drawings.

Wind direction conversion centrifugal blower 300 according to the present invention is a housing 310, a fan casing 320, a centrifugal blow fan 330, a fan casing drive motor 340, as shown in Figures 4 and 5, And a control unit 350.

The housing 310 is preferably manufactured in a box shape in the space utilization surface. Vents 311a and 311b are formed at front and rear ends of the housing 310, respectively, and the vents communicate with each other indoors or outdoors. The housing 310 may be directly installed on the sidewall of the building so that the air vents 311a and 311b may be directly exposed to the inside and the outside, but the flanges may be coupled to the air vents 311a and 311b to allow intake or exhaust. It can also be connected to

As described above, in the conventional air conditioner 100, since the ducts connected to the indoor and outdoor spaces had to be installed in two lines, respectively, the ceiling space was greatly needed, whereas the wind direction conversion air conditioner 300 according to the present invention was It can be installed in a ductless manner or only one line of duct connected to the indoor and outdoor, it can be installed in a narrow space will be a big feature of the present invention.

 In addition, the front and rear ends of the housing 310 may be configured by combining a filter for filtering the foreign matter of the intake or exhaust air, hanger 312 for easy installation on the outer surface of the housing 310 Can be mounted.

The fan casing 320 is installed inside the housing 310, and an exhaust port 321 is formed at a side surface thereof, and an inlet port 322 is formed at an upper surface thereof. The centrifugal blower fan 330 is mounted inside the fan casing 320 and operated by a fan driving motor, and the fan casing driving motor 340 watches the fan casing 320 based on the pan casing central axis. It rotates in the direction or counterclockwise direction. (See Figures 5 and 6)

That is, the fan casing 320 is rotated clockwise or counterclockwise by the fan casing driving motor 340 which will be described later, and thus the direction in which the exhaust port 321 is directed is changed. That is, the wind direction converting air conditioner 300 according to the present invention takes the manner of converting the wind direction by adjusting the position of the exhaust port 321 while the fan casing 320 rotates to constitute the fan casing 320 itself. And the configuration for rotating the pan casing 320 may be the biggest feature of the present invention.

The pan casing 320 is preferably configured in a cylindrical shape for easy rotation and space efficiency. On the other hand, the inside of the fan casing 320 may take a suitable shape according to the type of the centrifugal blower (330). The air sucked from the indoor or outdoor flows into the fan casing 320 through the inlet 322 of the upper surface of the fan casing, and is pan-cased by the centrifugal blower fan 330 rotating inside the fan casing 320. It is discharged to the exhaust port 321 of the side. In this case, when the windbreak wall 323 is formed along the upper edge of the fan casing exhaust port 321, most of the air introduced into the housing 310 does not leak out to other places, and the fan casing intake port 322 is formed. It may be introduced to be discharged to the exhaust port 321.

The centrifugal blowing fan 330 refers to all vanes that rotate with a plurality of vanes (or wings) arranged at equal intervals on the circumference such as a turbo fan, a sirocco fan, and the like. The centrifugal blower fan 330 is configured to rotate by a drive motor.

Meanwhile, as illustrated in FIG. 6, a plurality of bearings 324 may be mounted on the lower end of the pan casing 320 to facilitate the rotational movement of the pan casing 320. Since the fan casing lower bearing 324 rolls in contact with the bottom of the housing 310, friction of the pan casing 320 may be greatly reduced.

In addition, the housing 310 may be integrally installed, but may be configured to further include a motor fixing plate 350 installed above the fan casing 320 and on which the fan casing driving motor 340 is mounted. At this time, the fan casing 320 is coupled to the windshield 323 to cover the upper end of the pan casing 230, and further comprises a cover plate 325 which is installed to be integral with the pan casing 320 In addition, when a plurality of bearings (not shown) rolled in contact with the bottom surface of the motor fixing plate is mounted on the upper surface of the cover plate 325, the fan casing even when the wind direction conversion air conditioner 300 according to the present invention is installed upside down. It can be configured to continue the rotational movement of. (See Fig. 5)

When the pan casing 320 is formed in a cylindrical shape, the locking jaw 326 is formed on both sides of the pan casing 320, and the rotation of the pan casing 320 is stopped by the locking casing 326. It is possible to install a stopper 390 to serve. That is, when the locking jaw 326 formed on both sides of the pan casing 320 rotates the pan casing drive motor 340 for a time that goes to the stopper 390, and is reversely rotated, it is caught by the opposite stopper 390. In order to facilitate the change of direction of the fan casing exhaust port (321). In this case, the stopper 390 may be adjusted, and the control unit 360 to be described later may be adjusted to change the direction of the fan casing exhaust port 321 in various directions. 5 (a) and 5 (b) show a state in which the fan casing 320 is rotated so that the exhaust ports 321 are directed in opposite directions. The stopper 390 may be mounted on the housing 310.

In order for the fan casing 320 to be smoother and more stable in rotation, the lower fixing plate 370 is installed to be fixed at the inner bottom of the housing 310 so as to contact the fan casing lower bearing 324 and the upper fixing plate 380. ) Is installed to be fixed under the motor fixing plate 350 inside the housing so as to contact the cover plate bearing (not shown). That is, the bearing 324 mounted on the lower end of the pan casing 320 rolls while contacting the upper surface of the lower fixing plate 370, and the bearing mounted on the upper surface of the cover plate 325 rolls while contacting the lower surface of the upper fixing plate 380. It is configured to allow the pan casing 320 to rotate.

At this time, the plurality of bearings installed on the lower surface of the fan casing 320 and the upper cover plate 325 are disposed on a different distance from the centrifugal, and the fan casing 320 is a stopper (top) on the upper surface of the lower fixing plate 370. 390, the fixing groove 371 is formed in a portion corresponding to the position of the fan casing bearing 324 when the rotation is stopped, the bottom of the upper fixing plate 380, the pan casing 320 is a stopper ( 390 may be configured such that a cam (not shown) is formed at a portion corresponding to the position of the bearing of the cover plate 325 when the rotation is stopped.

The above configuration is because the bearing 324 protruding to the lower surface of the fan casing 320 rolls in contact with the lower fixing plate 370 and inevitably occurs, a gap between the lower end of the pan casing 320 and the lower fixing plate 370. It is to increase the airtightness of the wind direction conversion air conditioner 300 to eliminate. That is, the bearing 324 installed on the lower surface of the pan casing 320 is configured to freely roll on the lower fixing plate 370 to facilitate the rotational movement of the pan casing 320, but the pan casing catching jaw 326 is the stopper ( When the fan 320 is fixed and fixed, the fan casing 320 and the lower fixing plate 370 enter the fixing groove 371 formed on the upper surface of the lower fixing plate 370. The gap therebetween is configured to disappear so that the airtightness is increased after the direction of the fan casing exhaust port 321 is determined.

In addition, by forming a cam on the lower surface of the upper fixing plate 380 to the position corresponding to the position of the cover plate 325 bearing when the rotation is stopped by the stopper 390 of the fan casing 320, the pan casing As the bearing 324 of the lower surface falls into the fixing groove 371 of the lower fixing plate 370, the gap between the upper fixing plate 380 and the cover plate 325 is compensated by the cam to fix the upper fixing plate and the upper fixing plate. (380) to maintain the close state of the cover plate 325. The term "cam" is a generic term for a device for converting a rotational motion into a vertical motion. In the present invention, the fan casing 320 rotates and is pressed down by the cam so as to be in close contact with the downward motion. That is, when the fan casing 320 rotates, the lower fixing plate 370 and the pan casing 320, the cover plate 325, and the upper fixing plate 380 are opened to roll bearings, respectively, after the rotation is completed. The member is fixed while being in close contact.

In addition, when the lower fixing plate 370, the upper surface fixing groove 371 and the upper fixing plate 380 as described above, by the interaction of the cam, the wind direction conversion air conditioner 300 according to the present invention is closely installed and smooth regardless of the direction of gravity Operation is possible. Therefore, the wind direction converting air conditioner 300 according to the present invention does not interfere with the proper function even if installed upside down.

On the other hand, the fan casing 320 and the plurality of bearings installed in the upper and lower ends should be disposed on a different distance from the centrifugal. This is because if the plurality of bearings are disposed at the same distance from the centrifugal rotation, the rotational motion is prevented by the fixing groove 371 or the cam.

An air leakage preventing plate 381 may be formed at an edge of the upper fixing plate 380 to prevent a gap with the cover plate 325 generated when the fan casing 320 is caught by the stopper 390 and the rotation is stopped. have. The air leakage preventing plate 381 is a member that blocks a gap between the upper fixing plate 380 and the cover plate 325 and prevents the introduced air from leaking into the gap.

In the motor fixing plate 350 and the upper fixing plate 380, grooves 352 and 382 may be formed along the movement path of the fan driving motor wires to prevent the wires from being twisted due to the rotation of the fan driving motors.

The fan casing driving motor 340 is controlled in the rotation direction by the control unit 360, the condition that the control unit 350 adjusts the driving direction of the pan casing drive motor 340, the temperature, CO ₂ concentration, Various conditions such as time can be reflected.

In order to maintain a comfortable indoor environment in consideration of the temperature difference between the indoor and outdoor, it is preferable to adjust the direction of the exhaust casing 321 of the fan casing 320 according to the temperature change. For example, when a driving signal according to a user's operation is input, the temperature value is input from an indoor temperature sensor and an outdoor temperature sensor to determine whether the outdoor temperature is less than a preset temperature. The operation of the blower fan 330 is stopped to prevent device damage due to excessive driving of the wind direction conversion air conditioner 300. On the other hand, if the outdoor temperature is above the set temperature, the wind direction conversion air conditioner 300 operates, and if the absolute value of the temperature difference calculated by calculating the absolute difference between the indoor temperature and the outdoor temperature is within a specific range in advance The control signal for the rotation direction of the fan casing driving motor 340 is output to change the direction of the fan casing exhaust port 321 for a predetermined time.

A concrete example in which the controller 360 controls the fan casing driving motor 340 by a temperature difference between indoors and outdoors is as follows.

When the absolute value of the indoor / outdoor temperature difference exceeds a specific value, the controller 360 rotates the pan casing 320 clockwise or counterclockwise at a predetermined time interval, such that the exhaust port 321 of the pan casing 320 is rotated. Air supply cycle to communicate with the indoor, and exhaust cycle for allowing the exhaust port 321 of the fan casing 320 to communicate with the outdoors can be set to alternate periodically.

On the other hand, when the absolute value of the indoor / outdoor temperature difference is equal to or less than a specific value, only the air supply cycle may be maintained or an alternating cycle of the air supply cycle and the exhaust cycle may be set long.

In other words, if the temperature difference between the indoor and outdoor is small, the driving time is increased or only the air supply is made to provide sufficient ventilation. If the indoor and outdoor temperature difference is large, the driving time is shortened and the indoor temperature does not change rapidly due to the incoming outdoor air. By controlling the temperature difference between the supply and the exhaust, the ventilation time, etc., it is possible to maintain the optimum indoor temperature in accordance with the temperature deviation of the indoor and outdoor.

Of course, in addition to the air flow rate and the wind direction control method by the temperature sensor as described above can be applied to various control methods such as control by the CO ₂ sensor, timer setting, control by manual operation as described above.

On the other hand, the heat storage plate 410 is stacked in the housing 310, the heat exchanger 400 disposed so as to pass through before the indoor and outdoor air introduced into the housing 310 is discharged to the outside of the housing 310; The wind direction converting air conditioner 300 may be used.

The heat exchanger 400 is a device disposed in a passage through which indoor and outdoor air introduced into the housing 310 passes before being discharged to the outside of the housing 310. It is a device for storing the heat contained in the air so that the cool air is discharged to the room, and when the indoor air is discharged to the outside, the introduced heat is discharged, and in the winter, the heat exchange is contrary to the summer.

7 illustrates an embodiment of the heat exchanger 400 according to the present invention, and FIG. 8 illustrates a detailed view of the support block 420 and the heat storage plate 410 of the heat exchanger 400. As illustrated, the heat exchange part 400 is configured by stacking heat storage plates 410. The heat storage plate 410 may be composed of any one of charcoal, metal, synthetic resin, and fiber.

 On the other hand, the heat exchange unit 400, the support block 420 is fitted to each corner of the heat storage plate 410, respectively, coupled to the upper and lower; And finishing plates 430a and 430b fitted to the upper surface of the uppermost heat storage plate and the lower surface of the lowermost heat storage plate, respectively. It can be configured to include more.

At this time, the support block 420, the body portion 421; An elastic fitting portion 422 formed on a side of the body portion 421 and fitted to an edge of the heat storage plate 410; A connection guide protrusion 423 mounted on an upper surface of the body portion 421; A connection guide groove 424 formed on a lower surface of the body portion so that the connection guide protrusion 423 of the lower support block is inserted therein; A fixing groove 425 formed at one corner of the body portion 421 and a fixing jaw 425 formed at one edge of the body portion 421 to be fixed to the fixing groove 426 of the upper support block; It is configured to include. Such a configuration is devised to overcome the difficulty of lamination due to the tolerance of the heat storage plate 410 made of charcoal or the like.

The elastic fitting portion 422 is manufactured by using an elastic material such as rubber or synthetic resin to fix the heat storage plate 410 regardless of the thickness tolerance of the heat storage plate 410. After inserting the support block 420 at each corner of the heat storage plate 410 is laminated using the connection guide protrusion 423 and the connection guide groove 424. In this case, the connection guide groove 424 may be difficult to fit between the connection guide protrusion 423 of the lower heat storage plate and the connection guide groove 424 of the upper heat storage plate due to the width tolerance of the heat storage plate 410. It is preferable to form a larger diameter than the connection guide projection (423). In addition, the heat storage plate 410 is formed by combining the groove-jaw with the fixing jaw 425 of the lower heat storage plate and the fixing groove 426 of the upper heat storage plate. When dismantling the stacked heat storage plate 410, the fixing jaw 425 is configured to be removed. After stacking the heat storage plates 410 in a predetermined height in such a manner, and fixing the finishing plates 430a and 430b on the bottom of the bottom heat storage plate and on the top heat storage plate, the heat storage plate 410 itself is hardly pulled out and impacted. The heat exchanger 400 is also easy to absorb is completed.

On the other hand, at the upper edge of the motor fixing plate 350, by forming a leakage preventing jaw 351 to prevent the air sucked into the housing 310 without passing through the heat exchange unit 400 (wind direction conversion air conditioner ( The airtightness of 300) can be improved. That is, the air introduced into the housing 310 is prevented from escaping onto the motor fixing plate 350 by the leak preventing jaw 351, and is configured to be forced out through the fan casing 320.

9 illustrates the flow of air during exhaust and air supply using the wind direction converting air conditioner according to the present invention. Fig. 9A shows an example using a sirocco fan, and Fig. 9B shows an example using a turbofan, but the principles are the same.

Hereinafter, the vent hole at the front end of the housing communicates with the interior, and the vent hole at the rear end of the housing will be described with reference to an example installed to communicate with the outside as follows. When the indoor air is discharged to the outside, the fan casing 320 is rotated so that the exhaust port 321 faces the rear end of the housing 310, and the indoor air is provided with the vent 311a and the fan casing 320 in front of the housing 310. Inlet 322-centrifugal blower fan 330-exhaust casing 321 of the fan casing 320-heat exchanger 400-through the vent (311b) of the rear end of the housing 310 to be discharged to the outside .

On the contrary, when the outdoor air is introduced into the room, the fan casing 320 is rotated so that the exhaust port 321 faces the front end of the housing 310, so that the outdoor air is provided with the vent 311b of the rear end of the housing 310-heat exchange. Part 400-Inlet port 322 of the fan casing 320-Centrifugal blower fan 330-Exhaust port 321 of the fan casing 320-Passing through the vents (311a) in front of the housing 310 to the room To inflow.

Using the wind direction conversion air conditioner of the present invention as described above has the following effects.

First, it can be installed compactly with a single line of duct in a narrow ceiling space or directly connected to the side wall of a building without a duct.

Second, since the wind direction of the discharged air can be converted by rotating the fan casing, there is no element that obstructs the air flow in the air conditioner, which is advantageous in securing the air volume.

Third, the bearings can be installed on the bottom and cover plate of the fan casing to facilitate the rotation of the fan casing, and the airtightness of the fan casing, the air leakage preventing plate of the upper fixing plate, and the leakage preventing jaw of the motor fixing plate can be ensured. It can be secured.

Fourth, even if the wind direction conversion air conditioner is turned upside down during transportation or installation, it is composed of bearings mounted on the lower and upper cover of the fan casing, fixing grooves formed on the upper surface of the lower fixing plate, and cams formed on the lower surface of the upper fixing plate. The rotation of the pan casing can be prevented.

Fifth, there is no difference in fan performance and efficiency in the forward-backward (clockwise-counterclockwise) operation of the centrifugal blower fan.

Sixth, the fan casing is rotated, but because one blower fan is used, overall power consumption is reduced and manufacturing cost is lower than that of the conventional air conditioner.

Seventh, by further comprising a heat exchanger made of a material such as charcoal for heat transfer and heat accumulation, it is possible to save energy. When configuring the heat exchange unit, it is possible to easily and firmly stack the heat storage plate by using a support block and a finish plate.
