Description

Combined laundry washing and drying equipment

The present invention relates to a washing and drying device, in particular to a combined clothes washing and drying device.

It is a common household appliance configuration to install a washing machine and a dryer at home. The combination of the two can provide users with better convenience in washing, dehydrating, drying, etc. However, general washing machines and dryers are household appliances that operate independently. Even if users install a washing machine and a dryer at the same time, they can only use the functions of the two devices separately and fail to obtain additional convenience. In addition, installing a washing machine and a dryer at the same time will occupy a larger residential space, affecting the quality of living.

Therefore, one of the objects of the present invention is to provide a composite clothes washing and drying device that can solve the above-mentioned problems.

Therefore, in some embodiments of the composite clothes washing and drying apparatus of the present invention, a clothes drying device and a washing and drying device are included. The clothes drying device includes a clothes drying machine housing, a clothes drying door arranged at the front side of the clothes drying machine housing, a clothes drying tub arranged in the clothes drying machine housing for accommodating clothes to be dried, a hot air generating unit arranged in the clothes drying machine housing for heating air, and a clothes drying air duct assembly arranged in the clothes drying machine housing and connected to the clothes drying tub and the hot air generating unit. The clothes drying air duct assembly has a clothes drying return air duct connected to the rear side of the clothes drying tank, a clothes drying inlet air duct connected to the front side of the clothes drying tank, a return air valve connected to the clothes drying return air duct, an inlet air valve connected to the clothes drying inlet air duct, a return air connecting duct connected to the hot air generating unit and the return air valve, and an inlet air connecting duct connected to the hot air generating unit and the inlet air valve. The washing and drying device comprises a washing and drying machine casing adjacent to the drying machine casing, a washing and drying door arranged at the front side of the washing and drying machine casing, a washing and drying tub arranged in the washing and drying machine casing for accommodating clothes to be washed and dried, and a washing and drying air duct assembly arranged in the drying machine casing and the washing and drying machine casing and connecting the washing and drying tub and the clothes drying air duct assembly. The washing and drying air duct assembly has a washing and drying return air duct connecting the rear side of the washing and drying tub and the return air valve, and a washing and drying air inlet duct connecting the front side of the washing and drying tub and the air inlet valve.

Among them, the combined clothes washing and drying equipment can operate in a combined drying mode. In the combined drying mode, the return air valve is switched to allow the air in the drying return air duct and the washing and drying return air duct to flow to the return air connecting duct, and the air inlet valve is switched to allow the air in the air inlet connecting duct to flow to the drying air inlet duct and the washing and drying air inlet duct, so that the air heated by the hot air generating unit passes through the air inlet connecting duct, the drying air inlet duct, and the washing and drying air inlet duct from the front side into the drying tub and the washing and drying tub, and the humid air in the drying tub and the washing and drying tub passes through the drying return air duct, the washing and drying return air duct, and the return air connecting duct from the back side into the hot air generating unit.

In some embodiments, the combined clothes washing and drying device can also operate in a basic drying mode. In the basic drying mode, the return air valve is switched to allow the air in the drying return air duct to flow to the return air connecting duct and prevent the air in the washing and drying return air duct from flowing to the return air connecting duct, and the air inlet valve is switched to allow the air in the inlet connecting duct to flow to the drying inlet duct and prevent the air in the inlet connecting duct from flowing to the washing and drying inlet duct, thereby allowing the air heated by the hot air generating unit to flow through the inlet connecting duct and the drying inlet duct from the front side into the drying tub, and allowing the humid air in the drying tub to flow through the drying return air duct and the return air connecting duct from the back side into the hot air generating unit.

In some embodiments, the drying device further includes a filter disposed side by side with the hot air generating unit, the filter being disposed between the hot air generating unit and the return air connecting duct, connected to the return air connecting duct, and capable of being drawn out and replaced from the front side. In the combined drying mode, the humid air in the return air connecting duct first flows through the filter and then flows into the hot air generating unit.

In some embodiments, the hot air generating unit has a condenser and a heater. In the combined drying mode, the humid air flowing from the return air connection duct into the hot air generating unit is first processed by the condenser to remove moisture, and then heated by the heater.

In some implementations, the washing and drying device is stacked under the clothes drying device, and the hot air generating unit, the clothes drying air duct assembly and the washing and drying air duct assembly are mainly arranged between the clothes drying tub and the washing and drying tub.

Another object of the present invention is to provide a combined clothes washing and drying device. The combined clothes washing and drying device comprises two washing and drying devices, a hot air generating unit, a clothes drying air duct assembly and a washing and drying air duct assembly. The washing and drying devices are arranged adjacent to each other, and each washing and drying device comprises a washing and drying machine housing, a washing and drying door arranged at the front side of the washing and drying machine housing, and a washing and drying tank arranged in the washing and drying machine housing for accommodating clothes to be washed and dried. The hot air generating unit is arranged in one of the washing and drying machine housings for heating air. The clothes drying air duct assembly is arranged in the washer-dryer housing provided with the hot air generating unit, and comprises a clothes drying return air duct connected to the rear side of the corresponding washing and drying tub, a clothes drying inlet air duct connected to the front side of the corresponding washing and drying tub, a return air valve connected to the clothes drying return air duct, an inlet air valve connected to the clothes drying inlet air duct, a return air connecting duct connected to the hot air generating unit and the return air valve, and an inlet air connecting duct connected to the hot air generating unit and the inlet air valve. The washing and drying air duct assembly comprises a washing and drying return air duct connected to the rear side of another washing and drying tub and the return air valve, and a washing and drying inlet air duct connected to the front side of another washing and drying tub and the inlet air valve. Among them, the combined clothes washing and drying equipment can operate in a combined drying mode. In the combined drying mode, the return air valve is switched to allow the air in the drying return air duct and the washing and drying return air duct to flow to the return air connecting duct, and the air inlet valve is switched to allow the air in the inlet connecting duct to flow to the drying inlet duct and the washing and drying inlet duct, so that the air heated by the hot air generating unit passes through the inlet connecting duct, the drying inlet duct, and the washing and drying inlet duct from the front side to flow into the washing and drying tubs, and the humid air in the drying tubs passes through the drying return air duct, the washing and drying return air duct, and the return air connecting duct to flow into the hot air generating unit from the back side.

In some embodiments, the combined clothes washing and drying device can also operate in a basic drying mode. In the basic drying mode, the return air valve is switched to allow the air in the drying return air duct to flow to the return air connecting duct and prevent the air in the washing and drying return air duct from flowing to the return air connecting duct, and the air inlet valve is switched to allow the air in the inlet connecting duct to flow to the drying air inlet duct and prevent the air in the inlet connecting duct from flowing to the washing and drying air inlet duct, thereby allowing the air heated by the hot air generating unit to flow through the inlet connecting duct and the drying air inlet duct from the front side into the corresponding washing and drying tub, and allowing the humid air in the corresponding washing and drying tub to flow through the drying return air duct and the return air connecting duct from the back side into the hot air generating unit.

The present invention has at least the following effects: by integrating the clothes drying device and the washing and drying device, the basic clothes drying mode or the combined clothes drying mode can be executed when only a single hot air generating unit is configured, thereby providing users with more usage options. In addition, allowing heated air to flow into the clothes drying tub and the washing and drying tub from the front side, and allowing humid air to flow out from the back side of the clothes drying tub and the washing and drying tub, helps to improve the clothes drying effect. In addition, the combined clothes washing and drying equipment can also be implemented in a state where two washing and drying devices work together, and the aforementioned operating functions can also be realized.

Referring to FIG. 1 and FIG. 2 , an embodiment of the composite clothes washing and drying device 100 of the present invention is shown, wherein FIG. 1 is a side view and FIG. 2 is a front view. The composite clothes washing and drying device 100 can be used for clothes washing, dehydrating, drying and other processing procedures, and includes a clothes drying device 1 and a washing and drying device 2.

The clothes drying device 1 is exemplified in a manner similar to a drum dryer, and includes a clothes drying machine housing 11, a clothes drying door 12, a clothes drying tub 13, a hot air generating unit 14, a filter 15, a clothes drying air duct assembly 16, and components such as a motor, a transmission belt, a fan, a control circuit, and a control interface that are not shown in the figure.

The drying door 12 is disposed at the front side of the drying machine housing 11 (on the left side of the drawing in FIG. 1 ), and can close the front opening of the drying machine housing 11 during the drying process.

The drying tank 13 is disposed in the drying machine housing 11 for accommodating the clothes to be dried. During the drying process, the drying tank 13 can be driven by the motor and the transmission belt to rotate, thereby producing the effect of tumbling the clothes to be dried.

The hot air generating unit 14 is disposed in the clothes drying machine housing 11 and is used to heat the air to provide the hot air required for the clothes drying process. In this embodiment, the hot air generating unit 14 is, for example, a heat pump system and includes a condenser 141 and a heater 142. The condenser 141 is used to remove moisture from the air, and the heater 142 can heat the air.

The filter 15 is arranged side by side with the hot air generating unit 14 (on the left and right sides of the drawing in FIG. 2 ) to filter impurities in the air and can be pulled out and replaced from the drying door 12 on the front side of the drying machine housing 11 to facilitate maintenance of the drying device 1 .

The clothes drying air duct assembly 16 is arranged in the clothes drying machine housing 11 and is connected to the clothes drying tank 13, the hot air generating unit 14 and the filter 15. It has a clothes drying return air duct 161 connected to the rear side of the clothes drying tank 13 (the right side of the figure in FIG. 1 ), a clothes drying inlet air duct 162 connected to the front side of the clothes drying tank 13, a return air valve 163 connected to the clothes drying return air duct 161, an inlet air valve 164 connected to the clothes drying inlet air duct 162, a return air connecting duct 165 connecting the hot air generating unit 14 and the return air valve 163 and the filter, and an inlet air connecting duct 166 connecting the hot air generating unit 14 and the inlet air valve 164. By setting up the clothes drying air duct assembly 16, the air flow state during the clothes drying process can be controlled, and this part will be described in detail later.

The washing and drying device 2 is arranged adjacent to the drying device 1, and is exemplified in a manner similar to that of a drum-type washing machine, including a washing and drying machine housing 21, a washing and drying door 22, a washing and drying tank 23, a washing and drying air duct assembly 24, and components such as a motor, a transmission belt, water inlet and outlet pipes, a detergent box, and a control circuit that are not shown in the figure, and can be used for clothing processing such as washing, dehydrating, and drying.

The laundry door 22 is disposed at the front side of the laundry machine housing 21 and can close the front opening of the laundry machine housing 21 during the laundry processing process.

The washing and drying tank 23 is arranged in the washing and drying machine housing 21, and is used to accommodate the clothes to be washed and dried. During the clothes processing process, it can be driven by the aforementioned motor and transmission belt to rotate, so as to produce the effect of tumbling the clothes to be washed and dried, and can cooperate with the operation of the aforementioned water supply and drainage pipes, detergent box and other components to perform washing, dehydration and other procedures.

The washing and drying air duct assembly 24 is arranged in the drying machine shell 11 and the washing and drying machine shell 21, and is connected to the washing and drying tub 23 and the drying air duct assembly 16. It has a washing and drying return air duct 241 connected to the rear side of the washing and drying tub 23 and the return air valve 163, and a washing and drying air inlet duct 242 connected to the front side of the washing and drying tub 23 and the air inlet valve 164, which can provide an air flow path in the drying process of the washing and drying device 2.

3 and 4 , in actual operation, the combined clothes washing and drying device 100 can operate in a basic clothes drying mode as shown in FIG. 3 or in a combined clothes drying mode as shown in FIG. 4 .

Referring to FIG. 1 to FIG. 3 , in the basic clothes drying mode, only the clothes drying device 1 will perform the clothes drying process, and the washing and drying device 2 can be in an idle state or perform the washing and dehydrating process. In detail, in the basic clothes drying mode, the return air valve 163 is switched to allow the air of the clothes drying return air duct 161 to flow to the return air connecting duct 165 and prevent the air of the washing and drying return air duct 241 from flowing to the return air connecting duct 165, and the air inlet valve 164 is switched to allow the air of the air inlet connecting duct 166 to flow to the clothes drying air inlet duct 162 and prevent the air of the air inlet connecting duct 166 from flowing to the washing and drying air inlet duct 242. Therefore, as shown by the arrows in FIG3 , the above configuration allows the air A1 heated by the hot air generating unit 14 to flow into the clothes drying tub 13 from the front side through the air inlet connecting duct 166 and the clothes drying air inlet duct 162, and allows the humid air A2 in the clothes drying tub 13 to flow into the hot air generating unit 14 from the rear side through the clothes drying return duct and the return air connecting duct 165. When the clothes drying tub 13 stirs the clothes to be dried, the clothes are usually piled up at the rear side of the clothes drying tub 13. Therefore, by allowing the heated air to flow into the clothes drying tub 13 from the front side and allowing the humid air to flow out of the clothes drying tub 13 from the rear side, the heated air and the humid air can flow in a smooth path, which can effectively improve the efficiency of the clothes drying process. Furthermore, in this embodiment, the filter 15 is disposed between the hot air generating unit 14 and the return air connecting duct 165, so that the humid air A2 in the return air connecting duct 165 first flows through the filter 15 and then flows into the hot air generating unit 14, thereby ensuring air purity. In addition, the humid air flowing from the return air connecting duct 165 into the hot air generating unit 14 is first processed by the condenser 141 to remove moisture, and then heated by the heater 142. Such an operation method can ensure that the heated air A1 flowing into the drying tub 13 can meet the temperature and humidity conditions required for drying clothes.

Referring to Figures 1, 2 and 4, on the other hand, in the combined drying mode, the drying device 1 and the washing and drying device 2 will both perform the drying process. Specifically, the return air valve 163 is switched to allow the air in the drying return air duct 161 and the washing and drying return air duct 241 to flow to the return air connecting duct 165, and the inlet air valve 164 is switched to allow the air in the inlet connecting duct 166 to flow to the drying inlet air duct 162 and the washing and drying inlet air duct 242. Therefore, as shown by the arrows in FIG. 4 , the above configuration causes the air A1+B1 heated by the hot air generating unit 14 to flow into the clothes drying tub 13 and the clothes washing and drying tub 23 from the front through the air inlet connecting duct 166, the clothes drying air inlet duct 162, and the clothes washing and drying air inlet duct 242, respectively, and causes the humid air A2 and B2 in the clothes drying tub 13 and the clothes washing and drying tub 23 to flow into the hot air generating unit 14 from the rear through the clothes drying return air duct 161, the clothes washing and drying return air duct 241, and the return air connecting duct 165, respectively. In this way, in the combined clothes drying mode, the clothes drying device 1 and the clothes washing and drying device 2 can share the heated air A1+B1 provided by the hot air generating unit 14 to perform the clothes drying process. Furthermore, the humid air A2+B2 in the return air connection duct 165 flows through the filter 15, the condenser 141, and the heater 142 in sequence, and the clean, dry heated air A1+B1 flows from the inlet air connection duct 166 into the clothes drying inlet duct 162 and the washing and drying inlet duct 242 to perform the clothes drying process.

It should be particularly noted that in the present embodiment, the clothes drying device 1 and the washing and drying device 2 are illustrated in a vertically stacked manner, so that the washing and drying device 2 is stacked under the clothes drying device 1, and the hot air generating unit 14, the clothes drying air duct assembly 16 and the washing and drying air duct assembly 24 are mainly arranged between the clothes drying tub 13 and the washing and drying tub 23 to form a vertical configuration relationship. However, according to actual needs, the clothes drying device 1 and the washing and drying device 2 can also be placed side by side horizontally. In this case, the clothes drying device 1 and the washing and drying device 2 can be placed side by side left and right, for example, and the clothes drying tub 13, the hot air generating unit 14, the clothes drying air duct assembly 16, the washing and drying air duct assembly 24, and the clothes washing and drying tub 23 are arranged in a horizontal manner. This is also the way in which the composite clothes washing and drying equipment 100 can be implemented, and is not limited to the aforementioned description content and diagram configuration method.

Referring to FIG. 5 , in addition, although the combined laundry washing and drying device 100 in the aforementioned description is an example of a drying device 1 cooperating with a washing and drying device 2, the combined laundry washing and drying device 100 can also be implemented in a state where two washing and drying devices 2 cooperate with each other according to actual needs, mainly by replacing the washing and drying air duct assembly 24 of one of the washing and drying devices 2 (e.g., the washing and drying device 2 located at the top in FIG. 5 ) with the aforementioned drying air duct assembly 16, thereby replacing the drying return air duct 161 and the drying return air duct 162 in FIG. 5 with the drying return air duct assembly 163 in FIG. 5 with the drying return air duct assembly 164 in FIG. 5 with the drying return air duct assembly 165 in FIG. 5 with the drying return air duct assembly 166 in FIG. 5 with the drying return air duct assembly 167 in FIG. 5 with the drying return air duct assembly 168 in FIG. 5 with the drying return air duct assembly 169 in FIG. 5 with the drying return air duct assembly 161 in FIG. 5 with the drying return air duct assembly 164 in FIG. 5 with the drying return air duct assembly 165 in FIG. 5 with the drying return air duct assembly 166 in FIG. The air inlet duct 162 serves as an air flow path connected to the washing and drying tub 23 located above, and allows the hot air generating unit 14 (similar to FIG. 2 , not shown in FIG. 5 ), the filter 15 , the return air valve 163 , the air inlet valve 164 , the return air connecting duct 165 , the air inlet connecting duct 166 , the washing and drying return air duct 241 and the washing and drying inlet air duct 242 to be implemented through contents similar to the aforementioned description, so that the two cooperating washing and drying devices 2 can also realize the operation mode of the basic drying mode or the combined drying mode.

Therefore, in the variation implementation of Figure 5, the combined clothes washing and drying equipment 100 includes two washing and drying devices 2, a hot air generating unit 14 (similar to Figure 2, not shown in Figure 5), a filter 15, a clothes drying air duct assembly 16 and a washing and drying air duct assembly 24.

The washing and drying devices 2 are arranged adjacent to each other, and are stacked up and down as an example. Each washing and drying device 2 includes a washing and drying machine housing 21, a washing and drying door 22 arranged at the front side of the washing and drying machine housing 21, a washing and drying tank 23 arranged in the washing and drying machine housing 21, and components such as motors, transmission belts, water inlet and outlet pipes, detergent boxes, and control circuits that are not shown in the figure, so as to be used for washing, dehydrating, drying, and other clothing processing. The hot air generating unit 14 is arranged in one of the washing and drying machine housings 21 for heating air. In this embodiment, the hot air generating unit 14 is, for example, arranged in the upper washing and drying machine housing 21 but is not specifically shown. The clothes drying air duct assembly 16 is arranged in the washing and drying machine shell 21 provided with the hot air generating unit 14, and has a clothes drying return air duct 161 connected to the rear side of the corresponding washing and drying tank 23 (for example, the washing and drying tank 23 located at the top), a clothes drying air inlet duct 162 connected to the front side of the corresponding washing and drying tank 23 (for example, the washing and drying tank 23 located at the top), a return air valve 163 connected to the clothes drying return air duct 161, an air inlet valve 164 connected to the clothes drying air inlet duct 162, a return air connecting duct 165 connecting the hot air generating unit 14 and the return air valve 163, and an air inlet connecting duct 166 connecting the hot air generating unit 14 and the air inlet valve 164. The washing and drying air duct assembly 24 has a washing and drying return air duct 241 connected to the rear side of another washing and drying tank 23 (for example, the washing and drying tank 23 located below) and the return air valve 163, and a washing and drying inlet air duct 242 connected to the front side of another washing and drying tank 23 (for example, the washing and drying tank 23 located below) and the inlet air valve 164.

In the embodiment of FIG. 5 , the combined clothes washing and drying device 100 can also operate in a basic clothes drying mode or a combined clothes drying mode. In the basic clothes drying mode, the return air valve 163 is switched to allow the air in the clothes drying return air duct 161 to flow to the return air connecting duct 165 and prevent the air in the washing and drying return air duct 241 from flowing to the return air connecting duct 165, and the inlet air valve 164 is switched to allow the air in the inlet air connecting duct 166 to flow to the clothes drying inlet air duct 162 and prevent the air in the inlet air connecting duct 166 from flowing to the washing and drying inlet air duct 24 2, so that the air heated by the hot air generating unit 14 flows into the corresponding washing and drying tub 23 (for example, the washing and drying tub 23 located above) from the front side through the air inlet connecting duct 166 and the clothes drying air inlet duct 162, and the humid air in the corresponding washing and drying tub 23 flows into the hot air generating unit 14 from the rear side through the clothes drying return air duct 161 and the return air connecting duct 165. At this time, only one washing and drying device 2 executes the drying process. On the other hand, in the combined drying mode, the return air valve 163 is switched to allow the air in the drying return air duct 161 and the washing and drying return air duct 241 to flow to the return air connecting duct 165, and the inlet air valve 164 is switched to allow the air in the inlet air connecting duct 166 to flow to the drying inlet air duct 162 and the washing and drying inlet air duct 242, thereby heating the hot air generating unit 14. The air flows into the washing and drying tubs 23 from the front through the air inlet connecting duct 166, the clothes drying air inlet duct 162, and the washing and drying air inlet duct 242, and the humid air in the washing and drying tubs 23 flows into the hot air generating unit 14 from the back through the clothes drying return air duct 161, the washing and drying return air duct 241, and the return air connecting duct 165, so that both washing and drying devices 2 can perform the drying process.

In summary of the above description, the combined clothes washing and drying device 100 of the present invention can execute the basic clothes drying mode or the combined clothes drying mode when only a single hot air generating unit 14 is configured by means of the integrated arrangement of the clothes drying device 1 and the clothes washing and drying device 2, thereby providing users with more usage options. In addition, allowing heated air to flow into the clothes drying tank 13 and the clothes washing and drying tank 23 from the front, and allowing humid air to flow out from the back of the clothes drying tank 13 and the clothes washing and drying tank 23, helps to improve the clothes drying effect. In addition, the combined clothes washing and drying device 100 can also be implemented in a state where the two clothes washing and drying devices 2 operate in coordination, and the aforementioned operating functions can also be realized. Therefore, the combined clothes washing and drying device 100 can indeed achieve the purpose of the present invention.

However, the above is only an example of the implementation of the present invention, and it should not be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
