Description

Air conditioner having heating and cooling function

The present invention relates to a combined air-conditioning and air conditioner, and more particularly, to a combined air-conditioning and air conditioner for sufficiently heating a room.

In general, a combined air-conditioning and air conditioner sucks hot air from a room while cooling, exchanges the sucked hot air into cold air, and then discharges the cold air back into the room to cool the room to an appropriate temperature. In the heating, the cold air is sucked in the room, the cold air is exchanged into the hot air by heat exchange, and then the hot air is discharged back into the room to heat the room to an appropriate temperature.

Here, the air-conditioning cycle of the air-conditioning combined air conditioner, when the air conditioner during the cooling, the high-temperature, high-pressure gaseous refrigerant compressed by the compressor installed in the outdoor unit of the air conditioner passes through the four-way valve, the outdoor heat exchanger (condenser) of the outdoor unit Is exchanged with the external air passing through the outdoor heat exchanger while flowing in the outdoor heat exchanger, that is, the heat of the refrigerant is radiated to the outside air so that the refrigerant condenses to a liquid state of medium temperature (45 ° C.) and high pressure. The temperature of the air is raised.

The medium temperature high pressure liquid refrigerant passes through a capillary tube, and at the same time the pressure and the temperature are simultaneously dropped, the liquid refrigerant is partially gasified to be decompressed to a low temperature low pressure state, and the reduced pressure low temperature low pressure refrigerant is a heat exchanger of an indoor unit And heat exchange with the indoor air while flowing in the heat exchanger, that is, the refrigerant absorbs heat from the indoor air, evaporates to a low-temperature, low-pressure gas state, and flows back into the compressor of the outdoor unit, and the indoor air is cooled down. It is discharged to the room in a state that the room is cooled to an appropriate temperature.

In the heating, the refrigerant, which is a gaseous state of high temperature and high pressure, compressed by the compressor of the outdoor unit is sent to the heat exchanger (condenser) of the indoor unit while passing through the four-way valve to exchange heat with the indoor air passing through the heat exchanger while flowing in the heat exchanger. That is, the refrigerant radiates heat to the indoor air to condense to a liquid state of medium temperature (45 ° C.) and high pressure, and the indoor air receives a heat of the refrigerant to increase the temperature, and the indoor air having the elevated temperature is indoors. The room is heated to an appropriate temperature because it is discharged.

The liquid refrigerant of the medium temperature and high pressure passes through a capillary tube, and at the same time, the liquid refrigerant is partially gasified to decompress the liquid refrigerant into a low temperature low pressure state, and the reduced temperature low temperature low pressure refrigerant is an outdoor heat exchanger of an outdoor unit. Is exchanged with the external air while being flowed through the outdoor heat exchanger, that is, the refrigerant absorbs heat from the external air, evaporates to a low-temperature, low-pressure gas state, and flows back into the compressor of the outdoor unit. The temperature is lowered.

As shown in Figure 1 to 2b, the structure of the air-conditioning combined air conditioner is the main body 1 is divided into upper and lower, and the upper panel 2 is coupled to the upper front of the main body 1, The lower panel 14 is detachably coupled to the lower part of the front surface of the main body 1, and a control box 15 for generating a control signal to control the operation of the air conditioner is coupled to the lower side of the main body 1. It is.

The upper panel 2 is formed with an inlet opening 4 through which air in the room is sucked, and an inlet opening and closing member rotated by the driving force of the inlet opening / closing motor 6 to open and close the inlet opening 4 on the inlet opening 4 side. (5) is provided, and an air filter (7) is provided in the inlet opening / closing member (5) for filtering dust or foreign matter contained in the hot air of the room sucked into the main body (1).

The inlet opening / closing member 5 is formed in a triangular prism shape which is triangular in plan view, and one side of the inlet opening / closing member 5 is sucked into the body 1 through the inlet 4 through the inlet 4. The grill part 10 is formed, and the other side of the inlet opening and closing member 5 is formed with an open opening 11, and the other side of the inlet opening and closing member 5 is closed. It is formed of (12).

The main body 1 is provided with a cross flow fan 3 which is rotated by the driving force of the fan motor 13 so as to suck the air in the room into the main body 1 and discharge the sucked air into the room during heating and cooling. In the main body 1, a heat exchanger 8 through which a refrigerant flows is installed to heat exchange the air sucked through the suction port 4 by the rotational force of the cross flow fan 3, and the upper panel ( 2) is provided with a discharge port (9) for discharging the air flowing by the rotational force of the cross-flow fan 3 into the room, the discharge port (9) is adjusted to the left and right in the discharge direction of the discharged air The discharge grill 16 for guiding the air flowing along the rear guide 17 to the discharge port 9 is coupled.

When using a combined air-conditioning and air conditioner for cooling, when the user selects the cooling operation mode after supplying power to the air conditioner, the intake port blocking the intake port 4 formed in the upper panel 2 in the state where the air conditioner is stopped. The opening / closing member 5 is rotated by the inlet opening / closing motor 6 which generates a driving force in response to a control signal generated from the control box 15.

That is, the inlet 4 is blocked by the sealing part 12 of the inlet opening / closing member 5, and the grill portion 10 of the inlet opening / closing member 5 rotated by the driving force of the inlet opening / closing motor 6. When the suction port 4 is located, the rotation of the suction opening / closing member 5 is stopped and the suction opening 4 is opened.

As described above, when the inlet 4 is opened, the cross flow fan 3 installed in the main body 1 is rotated by the driving force of the fan motor 13, and is rotated by the rotational force of the rotated cross flow fan 3. The hot air of the room is sucked through the suction port 4, and the hot air of the room sucked through the suction port 4 passes through the grill part 10 and the opening part 11 of the inlet opening / closing member 5 and the main body. (1) is sucked into.

At this time, the dust and foreign substances contained in the hot air of the room sucked into the main body 1 by the air filter 7 installed behind the grill portion 10 of the inlet opening and closing member 5 is caught in the clean state Only air is sucked into the body 1.

On the other hand, the hot air of the room sucked into the main body 1 through the suction port 4 is combined with the main body 1, the heat exchange is made in the process of passing through the heat exchanger (8) where the cool refrigerant flows, the cold The cool air flows in the main body 1 by the rotational force of the cross flow fan 3 which is continuously rotated, that is, the air flowing along the rear guide 17 is discharged while passing through the discharge grill 16. Direction is adjusted and guided to the discharge port (9) is discharged into the room through the discharge port (9), the room is cooled to an appropriate temperature.

In this case, when the operation of the air conditioner is stopped, the inlet opening / closing motor 6 generates a driving force in a direction opposite to that of the cooling operation, and the inlet opening / closing member 5 is rotated along the inlet opening / closing motor 6 to intake ( 3) Since the sealing part 13 of the inlet opening and closing member 5 is located, the inlet 4 is blocked.

Next, when the air conditioner for heating and cooling is used as heating, the power supply is supplied to the air conditioner, and when the user selects the heating operation mode, the inlet opening and closing which closes the inlet 4 formed in the upper panel 2 while the air conditioner is stopped. As the member 5 is rotated by the inlet opening / closing motor 6 generating a driving force, the grille of the inlet opening / closing member 5 is connected to the inlet opening 4 blocked by the sealing part 12 of the inlet opening / closing member 5. Since the part 10 is located, the suction port 4 is opened.

As described above, when the inlet 4 is opened, the cold air in the room is installed in the main body 1 by the rotational force of the cross flow fan 3 which is rotated by receiving the driving force of the fan motor 13. The cold air is sucked into the main body 1 through the grill part 10 and the opening part 11 of the inlet opening / closing member 5.

The cold air of the room sucked into the main body 1 is combined with the main body 1 and heat exchange is performed in the course of passing through the heat exchanger 8 through which the hot refrigerant flows. The discharge direction is adjusted while passing along the discharge grill 16 while flowing along the rear guide 17 in the main body 1 by the rotating force of the cross flow fan 3 which is continuously rotated. As the air is heated to the discharge port 9, the air whose temperature is increased through the discharge port 9 is discharged to the room, and the room is heated to an appropriate temperature.

However, in such a conventional air-conditioning combined air conditioner, the refrigerant flowing in the heat exchanger 8 and the indoor air passing through the heat exchanger 8 are not sufficiently heat-exchanged when heating, and thus the room cannot be sufficiently heated. Consumer confidence in the product is lowered.

In addition, since the cooling and heating efficiency of the air conditioner is reduced by alternately cooling and heating the air conditioner by changing the flow path of the refrigerant in one system, there is also a problem in that the performance of the air conditioner is deteriorated.

The heating apparatus is provided with a plurality of halogen heaters 102 arranged at regular intervals in the heating port 14a to heat and emit heat and light, respectively, and on the rear surface of the lower panel 14, the heating port 14a. Each halogen heater 102 is installed and a reflecting plate 101 for radiating heat and light emitted from each halogen heater 102 into a room through a heating port 14a is coupled, and the reflecting plate 101 is provided. In the front of the distribution plate 103 is provided to dissipate heat radiated from each halogen heater 101 and radiated to the front of the main body 1 by the reflecting plate 101, the distribution plate 103 is It is formed in a honeycomb shape so as to evenly distribute heat radiated to the front of the main body 1.

A plurality of hooks 108 are formed at an outer side of the heating port 14a, and the hooks 108 may be smoothly attached to and detached from the heating port 14a at the outer surface of the reflecting plate 101. A plurality of locking holes 109 are inserted into and fastened to each other, and the center portion of each of the hooks 108 is cut to smoothly insert and remove the hooks 108 into each of the locking holes 109.

The blower is rotatably provided with a blower 106 for blowing heat emitted from the halogen heater 102 to the outside of the main body 1 above the halogen heater 102 in the reflector 101. In the upper part of the front surface 101, the guide member 107 which guides the heat | fever radiate | emitted by the halogen heater 102 and blown by the blower 106 to the exterior of the main body 1, ie, the room, is rotatably installed.

A plurality of heat dissipation holes are formed on the upper side of the reflecting plate 101 to discharge heat transferred from the halogen heater 102 to the rear of the halogen heater 102, that is, into the rear main body 1 of the reflecting plate 101. 101a is formed, and in front of the reflecting plate 101, a heating grill 104 that easily dissipates heat radiated from the halogen heater 102 to the outside and protects the user from the high temperature halogen heater 102. ) Is installed.

In front of the front heating port 14a of the lower panel 14, the heating port 14a is blocked when the heating device is not used, and the heating port 14a is opened to open the heating port 14a when the heating device is used. The door 105 which opens and closes) is detachably installed.

Since the halogen heater 102 is filled with halogen in a long rod-shaped glass sphere, when the power is applied, the halogen heater 102 emits high heat while generating heat and light, and the reflecting plate 101 radiates heat emitted from the halogen heater 102. It has a semi-cylindrical shape so that it can be radiated forward.

The operation of the present invention configured as described above is as follows.

In order to heat the room, the heating system provided at the upper part of the main body 1 of the combined air-conditioning and air conditioner is operated or the heating apparatus provided at the lower part of the main body 1 is operated, or the heating system and the heating device are operated. Operate simultaneously.

Here, the state of heating the room by operating only the heating device provided in the lower part of the main body 1 will be described.

First, the heating plate 14a of the lower panel 14 coupled to the lower front of the main body 1 is detached from the reflector 101 provided with a plurality of halogen heaters 102, that is, the reflector 101 is heated. When the reflector plate 101 is positioned on the front surface of the sphere 14a and then the reflector plate 101 is pushed toward the lower panel 14 and inserted into the heating port 14a, the reflector plate 101 is inserted into the plurality of engaging holes 109 formed on the outer surface of the reflector plate 101. Since the plurality of hooks 108 formed on the outer side of the heating port 14a are fastened to each other, the reflecting plate 101 is fixedly coupled to the heating port 14a.

Since each hook 108 is cut in the center portion of each hook 108, each hook 108 retracts inwardly from the cut-out portion when each hook 108 is inserted into the respective hook hole 109. The inner surface of each hook hole 109 is brought into close contact with the inner surface of each of the engaging holes 109, so that the reflecting plate 101 is firmly attached to the heating hole 14a. Combined.

In addition, when the reflecting plate 101 is separated from the heating port 14a of the lower panel 14, when the reflecting plate 101 is pulled in the opposite direction instead of the lower panel 14 side, each of the engaging holes 109 is formed. Each of the hooks 108 inserted into and pulled inwards from the cut-out portion is removed from each of the engaging holes 109, so that the reflector 101 is separated from the heating port 14a.

In addition, the reflection plate 101 provided with the plurality of halogen heaters 102 is coupled to the lower panel 14, and the door 105 is detachably coupled to the heating port 14a formed in the lower panel 14. .

Therefore, the door 105, which is detachably coupled to the heating port 14a formed in the lower panel 14 coupled to the lower front surface of the main body 1, is detached from the lower panel 14 and then operated to operate the heating apparatus. In other words, when the heating device of the air conditioner is stopped while the heating device is not used or the heating device is not used, the door 105 is coupled to the heating port 14a of the lower panel 14 to block the heating port 14a. The dust and foreign matters are introduced into the heating device through the 14a to prevent the dust and foreign matter from being attached to the outer periphery of the halogen heater 102, which is a component of the heating device, and at the same time, the exterior of the air conditioner for both heating and cooling is beautiful. When using the heating device, the door 105 is removed from the heating port 14a to operate the heating device with the heating port 14a open.

As described above, when the heating device is operated in a state in which the door 105 is removed from the heating port 14a, the plurality of arrays arranged at regular intervals in the reflecting plate 101 coupled to the heating port 14a of the lower panel 14 are operated. Heat and light are emitted and radiated by the two halogen heaters 102, and the emitted heat and light are radiated to the front of the main body 1 by the reflector 101 as much as possible.

At this time, a blower 106 rotated by a driving force of a driving motor (not shown) driven by receiving a control signal from the control box 15 is rotatably coupled above the halogen heater 102 in the reflector 101. Therefore, a part of the heat radiated by the reflector 101 is sent to the front of the reflector 101 while flowing in the reflector 101 according to the rotational force of the blower 106 being rotated, and the front of the reflector 101 The heat sent to is evenly distributed while passing through the distribution plate 103, the heat is distributed through the heating grill 104 is transmitted to the room through the heating port (14a).

In addition, the heat blown into the room through the heating port 14a of the lower panel 14 by the rotational force of the blower 106 is guided by the guide member 107 rotatably installed on the upper surface of the reflector 101. Not only is guided smoothly into the room, but also guided by the guide member 107 is blown to a far place in the room, while heating a large area of the room and at the same time to heat the far place quickly.

In this way, as the air temperature of the room is increased by the heat transferred to the room, the air whose temperature is raised rises upward due to natural convection and heats the room to an appropriate temperature, and at each of the halogen heaters 102. Ultraviolet rays are emitted, so you can expect a therapeutic effect.

On the other hand, most of the heat dissipated in each halogen heater 102 is radiated to the front of the main body 1 by the reflector plate 101, but a part of the heat dissipated in each halogen heater 102 is rear of each halogen heater 102 That is, the heat is transferred into the rear main body 1 of the reflecting plate 101. The heat rises upward in the main body 1 by the convection phenomenon and passes through the plurality of heat dissipation holes 101a formed on the upper part of the reflecting plate 101 to the room. Discharged.

As described above, the heat discharged to the room through the heat dissipation hole 103 and the heat radiated from the halogen heater 102 are radiated to the front of the main body 1 by the reflector 101 so that the combined heat is used to cool the room. As it flows, the room is heated.

As described above, the present invention provides a heating device in the lower part of the main body, so that even if the room cannot be sufficiently heated by the cooling and heating system installed in the upper part of the main body, the heating device of the combined air-conditioning and air conditioner is operated. Since the room can be sufficiently heated, the heating performance of the combined air-conditioning and air conditioner is improved, and the consumer's reliability of the product is improved.

Further, by installing a blower rotatably above each halogen heater in the reflecting plate, and providing a guide member for guiding heat blown by the blower to the upper part of the front of the reflecting plate to the room, the reflecting plate radiates from each of the halogen heaters. The high heat radiated is smoothly blown to the outside of the main body according to the rotational force of the blower to prevent the surface temperature of the lower panel from rising, thereby preventing safety accidents, and the high heat blown by the blower guide member Since the air is sent to a distant place in the room, there is also an effect of improving the heating performance of the air-conditioning combined air conditioner.
