Description

Technical Field

[0001] The present invention relates to the technical field of clothing care, and particularly to a clothing care device and a drying control method thereof. Background Art

[0002] With the improvement of people's living standards, clothing care devices with drying functions such as dryers and washer-dryers have gradually entered people's family lives.

[0003] The clothing treatment device usually includes an outer cylinder. The outer cylinder and the drying device are connected to form a drying path. The outer cylinder is connected with an air inlet duct and an air outlet duct. The drying device includes a condenser, a blower in the air inlet passage, and a heating element. The upper part of the condenser has a water inlet and an air outlet, and the lower part of the condenser has a water outlet and an air inlet. The water inlet is connected to the water inlet pipe of the clothing treatment device for introducing condensed water; the air outlet of the condenser is connected to the inlet of the air inlet duct of the outer cylinder; the air inlet of the condenser is connected to the outlet of the air outlet duct of the outer cylinder. Under the action of the blower, the air in the air inlet duct flows through the heating element and is heated, and then enters the outer cylinder to contact the wet clothes. Thus, the moisture on the clothes evaporates to form water vapor and flows out of the outer cylinder with the hot air, and enters the condenser through the air inlet of the condenser. The water vapor in the hot and humid air meets the condensed water in the condenser to form liquid water, which remains and is discharged from the water outlet. After condensation, dry air flows to the air inlet duct and is reheated and introduced into the outer cylinder, and so on in a cycle.

[0004] In addition, the clothing device also has a washing water discharge path. Usually, a sewage discharge port is provided on the outer cylinder, and a drain pipe and a drain pump are connected to the sewage discharge port. The washing water discharge path is used to discharge the washing water after washing the clothes.

[0005] During the washing and drying processes of the clothes, the lint on the clothes will also flow in the path along with the water flow or air flow. After the clothing treatment device has been used for a long time, the lint accumulated in the condenser and the outer cylinder gradually increases. In the long run, it will cause blockage of the condenser or the air duct, and then problems such as a reduction in air volume and a blower failure will occur. In the prior art, the lint can be discharged through the sewage discharge port and the water outlet of the condensed water. With this discharge method, lint exists in both paths, and the cleaning effect of the lint is poor.

[0006] Therefore, there is an urgent need to propose a clothing treatment device capable of automatically cleaning lint and a drying control method thereof to solve the above problems. Summary of the Invention

[0007] An object of the present invention is to provide a clothing treatment device, in which the lint generated during the drying process of the clothing treatment device can be directly discharged through the drying path, thereby reducing the pollution of the outer cylinder by the lint.

[0008] To achieve this purpose, the present invention adopts the following technical solutions:

[0009] A laundry treatment device, comprising:

[0010] An outer tub, the outer tub having a washing water outlet, an air inlet, and an air outlet, a blocking member being provided in the washing water outlet, and during the drying process, the blocking member being capable of blocking the washing water outlet;

[0011] A drying device, the drying device including a condenser, the condenser having a condensate water outlet, and the air inlet and the air outlet both being in communication with the condenser to form a drying passage.

[0012] Optionally, a guiding member is provided in the condenser, and the guiding member is capable of guiding lint and condensate water to the condensate water outlet.

[0013] Optionally, the laundry treatment device further includes a drainage pump, the washing water outlet being communicated with the drainage pump through a washing water discharge pipeline, and the condensate water outlet being communicated with the drainage pump through a condensate water pipeline.

[0014] Optionally, the blocking member includes a floating body, the floating body being capable of rising as the water level in the outer tub rises, and the height of the air inlet being higher than the upper surface of the floating body at the highest position.

[0015] Optionally, an induction coil is provided at the washing water outlet, the blocking member further includes a magnet provided in the floating body, and when the floating body contacts the induction coil, the magnet and the induction coil are in signal connection.

[0016] Another object of the present invention is to provide a drying control method for a laundry treatment device, and this drying control method can directly discharge the lint generated during the drying process through the drying passage, reducing the pollution of the outer tub by the lint.

[0017] To achieve this purpose, the present invention adopts the following technical solutions:

[0018] A drying control method for a laundry treatment device, applied to the above laundry treatment device, the drying control method for the laundry treatment device including:

[0019] S100. After the blocking member blocks the washing water outlet, the drying device is started;

[0020] S200. When the condensate water level in the condenser rises to a first preset water level L1, the drainage pump is turned on, and the lint is discharged along with the condensate water;

[0021] S300. When the condensate water level is lower than a second preset water level L2, the drainage pump stops.

[0022] Optionally, before S100, it further includes:

[0023] S000. Fill the outer cylinder with water to make the plug float.

[0024] Optionally, stop filling the outer cylinder with water when the water level reaches the second preset water level L2.

[0025] Optionally, after the plug seals the washing water outlet, the magnet in the plug is signal-connected to the induction coil at the washing water outlet and transmits a signal to the control unit. After receiving the signal, the control unit controls the drying device to start.

[0026] Optionally, the first preset water level L1 is lower than the height of the air inlet.

[0027] Beneficial effects:

[0028] In the clothes treatment device provided by the present invention, a plug is used to seal the washing water outlet during the drying process. Therefore, the lint that falls from the clothes during the drying process can only circulate in the drying path along with the hot and humid air. When the hot and humid air enters the condenser, the lint is discharged from the condensate outlet along with the condensate water. Since the washing water outlet is sealed, the lint will not flow through the washing water discharge path and can only be discharged through the drying path. Therefore, the residence time of the lint in the outer cylinder is reduced, and the pollution of the outer cylinder by the lint is effectively reduced.

[0029] The present invention also provides a drying control method for a clothes treatment device, which is used for the above-mentioned clothes treatment device. By adopting this drying control method, during the drying process, the washing water outlet is in a sealed state. Therefore, the lint will not flow through the washing water discharge path. The drying path operates independently, and the lint is discharged from the condensate outlet along with the condensate water, reducing the flow in the outer cylinder, thereby reducing the pollution of the outer cylinder by the lint.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0041] Referring to Figure 1 , this embodiment provides a laundry treatment device, including an outer tub 100 and a drying device 200. The outer tub 100 has a washing water outlet 110, an air inlet 120, and an air outlet 130. A blocking member 140 is disposed in the washing water outlet 110, and during the drying process, the blocking member 140 can block the washing water outlet 110. The drying device 200 includes a condenser 210, and the condenser 210 has a condensate outlet 211. Both the air inlet 120 and the air outlet 130 are communicated with the condenser 210 to form a drying passage.

[0042] During the drying process of the above laundry treatment device, the blocking member 140 is used to block the washing water outlet 110, so that lint falling from the clothes during the drying process can only circulate in the drying passage with the hot and humid air. When the hot and humid air enters the condenser 210, the lint is discharged from the condensate outlet 211 along with the condensate water. Since the washing water outlet 110 is blocked, the lint will not flow in the washing water discharge passage and can only be discharged through the drying passage. Therefore, the residence time of the lint in the outer tub 100 is reduced, and the pollution of the outer tub 100 by the lint is effectively reduced.

[0043] Further, the drying device 200 further includes a fan and a heating device. The fan is used to promote air circulation, and the heating device is used to heat the air flow.

[0044] Further, a guiding member 212 is disposed in the condenser 210, and the guiding member 212 can guide the lint and the condensate water to the condensate outlet 211.

[0045] Optionally, the guiding member 212 may be a plate-like structure disposed obliquely, and the condensate water can flow along the plate-like structure in the direction of the condensate outlet 211. Since the lint usually mixes into the condensate water after entering the condenser 210 with the air flow, the lint will be discharged from the condensate outlet 211 along with the condensate water.

[0046] Further, the laundry treatment device further includes a drain pump 300. The washing water outlet 110 is communicated with the drain pump 300 through a washing water discharge pipe 310, and the condensate outlet 211 is communicated with the drain pump 300 through a condensate water pipe 320.

[0047] In this embodiment, the washing water discharge pipeline 310 and the condensate water pipeline 320 share a drain pump 300. However, during the drying process and the washing process, the washing water discharge pipeline 310 and the condensate water pipeline 320 drain separately. During the drying process, the washing water outlet 110 is blocked by the blocking member 140 to enable the condensate water pipeline 320 to drain separately.

[0048] Furthermore, in this embodiment, the blocking member 140 includes a floating body 141. The floating body 141 can rise as the water level in the outer cylinder 100 increases, and the height of the air inlet 120 is higher than the upper surface of the floating body 141 at its highest position.

[0049] In this embodiment, the floating body 141 can be made of foaming material, and its center of gravity is always located at the lower part. After the blocking member 140 enters the water, the bottom is always located in the water. In other embodiments, the floating body 141 can be made of other materials as long as it can float in the water. It can be understood that the shape of the floating body 141 is set according to the washing water outlet 110, and it should be ensured that the washing water outlet 110 can be blocked after the floating body 141 rises to prevent the water in the outer cylinder 100 from flowing out through the washing water outlet 110. Optionally, the outer shape of the floating body 141 can be spherical or square, etc.

[0050] Optionally, a housing can be provided below the washing water outlet 110. The top of the housing is open as the washing water outlet 110, and the bottom is connected to the condensate water pipeline 320. The blocking member 140 is placed inside the housing. Optionally, the housing can be cylindrical or square, etc.

[0051] The height of the air inlet 120 is higher than the upper surface of the floating body 141 at its highest position, so as to reserve space for the washing water in the outer cylinder 100 and prevent the washing water from flowing into the condenser 210 through the air inlet 120 before the floating body 141 blocks the washing water outlet 110.

[0052] Furthermore, an induction coil 150 is provided at the washing water outlet 110. The blocking member 140 further includes a magnet 142 provided inside the floating body 141. When the floating body 141 contacts the induction coil 150, the magnet 142 and the induction coil 150 are signal-connected.

[0053] It can be understood that when the induction coil 150 senses a signal, it means that the floating body 141 has risen and isolated the inside of the outer cylinder 100 from the drain pump 300 at this time. The induction coil 150 is signal-connected to the control unit inside the laundry treatment device, and the control unit is used to receive the signal and control the operation of the drain pump 300. The setting of the control unit is a mature prior art in this field and will not be elaborated here.

[0054] Furthermore, this embodiment also provides a method for controlling the drying of a laundry treatment device. This method is applied to the above-mentioned laundry treatment device. The method for controlling the drying of this laundry treatment device includes:

[0055] After the S100 and the plugging member 140 block the washing water outlet 110, the drying device 200 is started.

[0056] S200. When the condensate water level in the condenser 210 rises to the first preset water level L1 (not shown in the figure), the drain pump 300 is turned on, and lint is discharged with the condensate water.

[0057] S300. When the condensate water level is lower than the second preset water level L2, the drain pump 300 stops.

[0058] The above S100-S300 are used during the drying process of the clothes. The control method for the washing process of this clothes processing device is a mature prior art in the field and will not be described herein. By adopting the above drying control method, during the drying process, the washing water outlet 110 is in a blocked state. Therefore, lint will not flow through the washing water discharge passage. The drying passage operates independently, and lint is discharged from the condensate water outlet 211 with the condensate water, reducing the flow in the outer cylinder 100, thereby being able to reduce the pollution of the outer cylinder 100 by lint.

[0059] It can be understood that after the drain pump 300 stops, if the drying process continues, the condensate water continues to increase. When the water level rises to the first preset water level L1, the drain pump 300 is started again, and so on in a cycle. Obviously, the above first preset water level L1 is higher than the second preset water level L2, and the first preset water level L1 and the second preset water level L2 are set according to the usage requirements and are not specifically limited herein.

[0060] Further, before S100, it further includes:

[0061] S000. Water is injected into the outer cylinder 100 to make the plugging member 140 float.

[0062] Since the plugging member 140 in this embodiment is a floating body 141, the height of the plugging member 140 can be controlled by injecting water. In other embodiments, a solenoid valve or other components can be used to control the on-off of the condensate water outlet 211.

[0063] Optionally, in this embodiment, when water is injected into the outer cylinder 100 to the second preset water level L2, the water injection stops.

[0064] It can be understood that the amount of water injected when injecting water into the outer cylinder 100 should ensure that the plugging member 140 can rise to a position where it blocks the condensate water outlet 211. Of course, the first preset water level L1 is lower than the height of the air inlet 120 to prevent water from flowing into the condenser 210 through the air inlet 120. The setting of the water injection amount is based on the shape and volume of the outer cylinder 100 and the position of the air inlet 120.

[0065] Further, after the plugging member 140 plugs the washing water outlet 110, the magnet 142 in the plugging member 140 is signal-connected to the induction coil 150 at the washing water outlet 110 and sends a signal to the control unit. After receiving the signal, the control unit controls the drying device 200 to start.

[0066] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
