Description

Integrated dry device

The present invention relates to an integrated drying apparatus installed in a washing machine or a clothes dryer, and more particularly, the water generated by cooling the wet and hot air in the laundry room is discharged and the remaining air is heated to form hot dry air to circulate the laundry. It relates to an integrated drying device that can dry quickly and effectively.

In general, a washing machine equipped with a washing function and a drying function is a device for drying a laundry by blowing hot air using heat generated by a heat generating means into a laundry room after the washing process is finished.

For example, the drying washing machine is equipped with a heater and a blower fan in a general washing machine, when a series of washing processes such as washing, rinsing, and dehydration are completed, the heater and the blower fan are driven to transfer heat generated from the heater into the laundry room. It is a device that can realize a series of washing process by blowing the air, and subsequently raising the internal temperature by the internal air convection of the laundry room to dry the dehydrated laundry.

On the other hand, the clothes dryer injects high temperature air into the rotating drum which is rotated to stir the laundry contained therein, and discharges the hot and humid air containing the moisture of the laundry to the outside of the rotating drum, thereby speeding up the drying process of the laundry. It is a device to be performed.

Such a washing machine and a clothes dryer include an exhaust type for discharging high temperature and high humidity air and a condensation method for condensing high temperature and high humidity air and heating dry air to be circulated back into the laundry room. It is a trend to use an advantageous condensation type in terms of the back.

Such a condensation type washing machine and a clothes dryer are disclosed in various structures such as Korean Patent No. 10-0149915, Korean Patent No. 10-0442402, Korean Patent No. 10-0184189, Korean Patent No. 10-0487329, and the like.

In general, condensation-type washing machines or clothes dryers adopt a circulating refrigeration cycle consisting of a compression process, a condensation process, an expansion process, and an evaporation process.

That is, the refrigeration cycle configuration is driven by a motor and the low-temperature low-pressure gas refrigerant to a high-temperature high-pressure gas and sent to the condenser, and a cooling fan to condense the high-temperature high-pressure gas state refrigerant by a cooling fan to a high-temperature high-pressure liquid refrigerant state A condenser to make, a valve that opens and closes according to the gas pressure in the sensing container, and an expansion valve that suddenly expands the refrigerant into the evaporator to form a low-temperature, up-pressure liquid (fog), and cools it while the refrigerant in the fog changes to gas. The operation of the fan removes the heat from the air passing through the fins, providing four main components of the evaporator that cools the surroundings and turns the low pressure liquid into a low pressure gas.

This refrigeration cycle method is the key to maximize the cooling efficiency of the evaporator, that is, the cooling efficiency of the refrigeration cycle, depending on how fast and how to cool the condenser that generates a lot of heat by receiving high-temperature, high-pressure gas from the compressor. do.

However, the conventional condensation type washing machine or clothes dryer has a long overall line because each component is installed separately and has a complicated structure such that separate fans must be used for the condenser and the evaporator. In addition, in order to be applied in a washing machine and a clothes dryer, the volume of the device is increased, and energy consumption is large, and drying time is long.

In particular, the conventional refrigeration cycle method has a disadvantage in the manufacturing, such as cooling the condenser to increase the cooling rate and efficiency only by the cooling fan to reduce the cooling rate and cooling efficiency, and also install a separate blower fan in the evaporator. As a result, the condensation efficiency of the laundry room air is reduced, which takes a long time to dry.

Accordingly, the present invention has been made in view of the above, and the condenser is generated in the fan and the evaporator through an optimal assembly combination in which the evaporator and the condenser of the refrigeration cycle are arranged back and forth in parallel and one fan is disposed therebetween. By implementing a new type of drying system that cools by the cold air and circulates the wet and hot air of the laundry room into hot dry air, the overall structure can be simplified, compressor capacity and fan quantity can be minimized. It can be, in particular, to provide an integrated drying device that can increase the drying efficiency of the laundry as much as possible.

In order to achieve the above object, the integrated drying apparatus provided in the present invention has the following features.

The integrated drying apparatus includes a case having a front chamber connected to an air inlet for introducing wet and hot air of a laundry room, and a rear chamber connected to an air outlet for supplying high temperature dry air to the laundry room. Evaporators and condensers, which are installed in the front chamber and the rear chamber, are arranged in parallel with each other in front and rear, and form a refrigerant circulation cycle together with the compressor and the expansion valve. It includes a fan to guide the air to the condenser side, it is possible to dry the laundry in a circulating manner to send the wet and hot air of the laundry room introduced through the air inlet through the evaporator and the condenser to the hot dry air, and back to the laundry room, The compressor and expansion valve is a case Each of the upper and lower portions of the evaporator and the condenser and the refrigeration cycle can be configured close to each other, and the front chamber to which the evaporator belongs, the rear chamber to which the condenser belongs and the intermediate chamber to which the fan belongs are each independent.

By drying, it is possible to minimize the compressor capacity and the number of fans as well as simplify the structure, in particular there is an advantage that can effectively dry the laundry.

Second, by adopting a method of heating the low temperature dry air passing through the front evaporator to the high temperature dry air by heating the rear condenser, there is an advantage that can maximize the cooling efficiency as well as the power saving effect associated with the operation of the device.

That is, by cooling the condenser main body with the coolant generated in the evaporator, the cooling efficiency of the device can be maximized. Also, the gas is lowered as the high temperature and high pressure gas passes through the condenser having a good cooling condition, and the expansion valve and the evaporator, which are later processes, are used. As the load of the evaporator and condenser are minimized, it is possible to minimize the capacity of the compressor. Therefore, it is possible to maximize the cooling efficiency of the evaporator as well as to maximize the drying efficiency of the device. have.

In addition, an air inlet 10 is formed in the front chamber 11 of the case 14 so that wet and hot air of the laundry room is inside the case 14, that is, inside the front chamber 11. You can enter

Here, the drain valve 30 is provided at the lower end of the front chamber 11, the drain valve 30 at this time is the water generated inside the front chamber 11, that is, the humid evaporator 17 is cold and hot air By cooling the water produced by the) to serve to drain the case.

In addition, an air outlet 12 is formed at a lower end of the rear chamber 13 of the case 14, and the hot dry air passing through the condenser 18 described later through the air outlet 12 is moved to the laundry room side. Can be sent.

Here, a plurality of diaphragms 28 arranged in a zigzag form along the top and bottom in the form of a "-" bar may be installed on the rear inner wall of the rear chamber 13, in which the diaphragm 28 is the rear chamber 13. It will serve to delay the residence time of air in.

Accordingly, the flow of hot dry air passing through the condenser 18 in the rear chamber 13 is delayed by the diaphragm 28, so that the thermal efficiency of the hot dry air can be further improved. do.

In addition, between the air inlet 10 of the front chamber 11 and the outlet of the washing machine is connected to the inlet pipe 23 made of a hose or the like, the air outlet 12 and the washing machine of the rear chamber 13 Between the inlet of the outlet pipe 24 also made of a hose or the like is connected.

Accordingly, a circulation path of air passing between the laundry room of the washing machine and each chamber of the case 14 may be formed.

At this time, each end of the inlet side pipe 23 and the outlet side pipe 24 is provided with a coupler 25 that can be connected or separated, so that the inlet side pipe 23 and the outlet side pipe 24 are washed. It can be connected to the side or the clothes dryer side.

In addition, solenoid valves 22a and 22b are installed in the inlet pipe 23 and the outlet pipe 24, respectively, and the solenoid valves 22a and 22b are introduced into and out of the case 14. You can shut off the air.

In addition, respective temperature sensors 21a, 21b, and 21c may be installed in the interior of the front chamber 11, the interior of the rear chamber 13, and the discharge side pipe 24.

For example, when the surface temperature of the internal evaporator 17 falls below a set temperature, the temperature sensor 21a installed inside the front chamber 11 is disconnected from a controller (not shown) to a proper temperature. The temperature sensor 21b installed inside the rear chamber 13 may be set to an appropriate temperature by disconnecting an electrical connection from a controller (not shown) when the surface temperature of the internal condenser 18 rises above a predetermined temperature. The temperature sensor 21c installed in the discharge-side pipe 24 measures the temperature of the air flowing into the laundry room after passing through the auxiliary heater 27 to be described later and rises above the set temperature. The electrical connection of the auxiliary heater 27 is cut off from the appropriate temperature.

In particular, the present invention provides a refrigeration cycle that can achieve the optimal combination using the structure of the case (14).

To this end, an evaporator 17 is installed in the front chamber 11 of the case 14 and a condenser 18 is installed in the rear chamber 13, and between the front chamber 11 and the rear chamber 13. The fan 20 is installed in the intermediate chamber 19 formed in the chamber.

That is, the evaporator 17, the fan 20, and the condenser 18 may be arranged side by side in the front-rear direction based on the flow direction of the air.

Accordingly, when the fan 20 operates, air in the front chamber 11 may flow to the rear chamber 13 after sequentially passing through the evaporator 17 and the condenser 18.

The fan 20 is preferably to be able to adjust the rotational speed in a control device (not shown). This makes it possible to change the circulation flow rate of air, and the higher the rotation speed, the faster the cooling rate of the condenser 18 in the rear chamber 13 can proceed. At this time, the rotational speed of the fan 20 can be adjusted based on the set temperature by the temperature sensor 21b installed in the rear chamber 13.

And, the compressor 15 constituting the refrigeration cycle with the evaporator 17 and the condenser 18 is installed on the upper portion of the case 14, and connected to the evaporator 17 side and the condenser 18 side, respectively, the line In addition, the expansion valve 16 is connected to the condenser 18 side and the evaporator 17 side together with the receiver dryer 29 to form a line.

Accordingly, a refrigeration cycle of the refrigerant circulation line leading to the evaporator 17 → the compressor 15 → the condenser 18 → the receiver drier 29 → the expansion valve 16 → the evaporator 17 can be made.

Here, the evaporator 17 takes the heat in the air passing through the fins by the operation of the fan 20 while the refrigerant in the fog state is changed into gas to cool the air (at this time, the refrigerant is low pressure liquid → low pressure gas). Will be

Accordingly, while the hot and humid air is passed through the evaporator 17, the heat is taken away and can be converted to low temperature dry air.

In addition, the compressor 15 is operated by a predetermined driving means such as a motor (not shown) to serve as a low-temperature low-pressure gas refrigerant to the condenser 18 to produce a high-temperature and high-pressure gas.

In addition, the condenser 18 serves to condense the refrigerant of the high temperature and high pressure gas state by the fan 20 to form a liquid refrigerant state of high temperature and high pressure.

Accordingly, the air that is converted into low-temperature dry air while passing through the cold evaporator 17 (water generated at this time is discharged to the drain valve) passes through the condenser 18 while cooling the condenser body while passing the air It can be heated and converted to hot dry air.

In addition, the receiver dryer 29 can be excluded in the installation configuration in the case of a small washing machine or a clothes dryer, and serves to store the refrigerant to absorb the moisture contained in the refrigerant and smoothly supply the refrigerant.

In addition, the expansion valve 16 serves to instantaneously expand the refrigerant toward the evaporator 17 to make the liquid (fog shape) of low temperature and low pressure.

On the other hand, as a means for further increasing the drying efficiency of the present invention, the auxiliary fan 26 and the auxiliary heater in the discharge side pipe 24 which is connected between the air outlet 12 of the case 14 and the laundry room of the washing machine (27) may be provided in turn, so that the hot dry air via the condenser 18 can be supplied to the laundry room side after being further heated secondly. In this case, a temperature sensor 21c may be installed at the rear discharge side pipe 24 of the auxiliary heater 27, and the temperature sensor 21c may be introduced into the laundry room 110 by turning on / off the auxiliary heater 27. It is possible to adjust the temperature of the air to be appropriately.

It is a cross section.

As shown in Figure 2 and 3, the integrated drying apparatus 100 is installed in a structure that is built in one side of the main body of the washing machine, drum washing machine, or clothes dryer, the inflow of the integrated drying device 100 is installed The side pipe 23 is connected to the upper part of the laundry room 110 in the tub washing machine, the drum washing machine, or the clothes dryer, and the discharge side pipe 24 is connected to the lower part of the laundry room 110.

Accordingly, the wet and hot air inside the laundry room 110 generated by the laundry drying is lifted upward by convection to enter the integrated drying device 100 as an assembly through the inlet pipe 23. The air introduced into the integrated drying apparatus 100 is converted into the cooled and heated high temperature air, and then the laundry room 110 is circulated through the discharge pipe 24 to the interior of the laundry room 110. Drying work for the laundry can be made.

Reference numeral 111 is a divider, and means for inducing the flow of air via the inner rotation drum of the laundry room by blocking the flow of air to the outside of the inner rotation drum of the laundry room (110).

Therefore, looking at the state of use of the integrated drying device is configured as follows.

Figure 4 is a cross-sectional view showing an operating state of the integrated drying apparatus according to an embodiment of the present invention.

As shown in FIG. 4, after the washing of the laundry in the washing machine is completed, the drying operation of the laundry may be continuously performed in connection with the operation of the integrated drying apparatus.

For example, when the integrated drying apparatus is operated after the end of washing, that is, when the operation of the refrigeration cycle and the operation of the fan 20 are started, the wet and hot air in the laundry room is guided along the suction side pipe 23 while the air intake 10 Through the evaporator 17 is introduced into the interior of the front chamber 11 is installed.

The air introduced into the front chamber 11 is cooled by dry air of low temperature while passing through the cold evaporator 17, and the liquid water is discharged through the drain valve 30, and the remaining air is fan 20 By the suction force of), it immediately flows into the rear chamber 13 in which the hot condenser 18 is installed.

At this time, the low temperature dry air introduced into the rear chamber 13 is converted into high temperature dry air by a heat exchange action with the condenser 18, and the high temperature dry air is an air outlet port of the rear chamber 13 12) and the discharge side pipe 24 is sent to the laundry room so that the drying operation for the laundry can be made quickly. At this time, the low temperature dry air (cold air) introduced into the rear chamber 13 simultaneously cools the main body of the condenser 18 while passing through the condenser 18, thereby increasing the cooling efficiency of the evaporator 17. .

Here, the high temperature dry air exiting the rear chamber 13 is accelerated once more by the auxiliary fan 20 installed in the discharge side pipe 24 before being sent into the laundry room and the auxiliary heater 27. Can be sent after being heated again.

As such, the process of circulating the air between the laundry room and the integrated drying apparatus, that is, the process of repeatedly making the wet and hot air generated during the drying process of the laundry into the low-temperature dry air and the high-temperature dry air and repeating the cycle, thereby rapidly drying the laundry. In addition, as the condenser is cooled by the cold of the evaporator, it is possible to maximize the drying efficiency by maximizing the cooling efficiency of the cooling cycle type evaporator.

Thus, in the present invention, by building an integrated drying system for drying the laundry using the optimal combination of cooling cycles through the proper arrangement of the evaporator, condenser, and fan, the overall structure of the expansion valve and receiver dryer Overload protection, compressor capacity can be reduced, and the number of fans can be reduced, which saves power and maximizes drying efficiency.
