Description

Technical Field

[0001] This invention belongs to the field of drying equipment, and specifically relates to a condensation system for a clothes dryer, a clothes dryer, and a control method for the clothes dryer. Background Technology

[0002] As a household appliance that can quickly dry clothes, clothes dryers allow people to wear dry and comfortable clothes even in humid weather, reduce the space required for drying clothes, and improve people's quality of life. Therefore, clothes dryers are becoming increasingly popular among users.

[0003] At the same time, with the application of dryers, users have put forward higher requirements for drying speed, drying uniformity and energy consumption. Therefore, the current improvement of dryers mainly focuses on how to improve drying speed while controlling the energy consumption of dryers.

[0004] To address this issue, Chinese invention patent application CN201510489302.4 discloses a pre-cooling device for a heat pump dryer, including a spraying device located between the evaporator inlet and the drying chamber to spray and cool the air duct. The spraying device includes a first water pump, spray heads, and water pipes. The first water pump extracts condensate from the water collection tray and sprays it into the air duct through the spray heads to achieve spray cooling of the circulating air in the air duct. Although the above solution improves the condensation effect by reusing the condensate of the dryer, the condensate remaining in the air duct may lead to increased humidity in the air duct, which is not conducive to the smooth drying process. Even if a plate heat exchanger is set in the pre-cooling device to achieve separate circulation of condensate, this solution increases the complexity of the structure inside the air duct, and the increased obstruction to the circulating air may reduce the circulation efficiency of the circulating air, which will also affect the drying efficiency.

[0005] Chinese utility model patent application number CN200920058233.1 discloses a drying chamber for an air source heat pump dryer, including a heat pump device installed across the air inlet and exhaust channels. Circulating air enters from the air inlet channel, is heated by the condenser, and then enters the drying chamber. A circulating fan ensures that part of the circulating air circulates fully within the drying chamber, while the other part is discharged from the exhaust channel after being condensed by the evaporator. This reduces the workload of the heat pump system and improves drying efficiency. Although the above solution can ensure that the temperature inside the drying chamber remains at a high level and improves drying efficiency, the circulating air comes from outside air, and the cleanliness of the clothes is affected by the environment in which the dryer is located. Furthermore, when the outside environment is humid, the high humidity air entering the drying chamber after heating may prevent the clothes from being completely dried.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] One of the objectives of this invention is to provide a condensation system for a clothes dryer that addresses the problems in the prior art. By setting up an auxiliary air duct connected to the circulating air duct, a portion of the circulating air with high moisture content is guided to a water collection section for condensation and discharge, thereby reducing the workload of the condensation device and improving drying efficiency.

[0008] Another object of the present invention is to provide a dryer having the above-mentioned condensation system, wherein the water collection section is connected to the water tank through a pipe, a water pump is provided on the pipe, the circulating air entering the water collection section enters the water tank along the pipe, and the water pump periodically sends the water in the water collection section into the water tank, so that the condensate in the water collection section always has a low temperature.

[0009] One objective of this invention is to provide a control method for the aforementioned dryer, wherein a water pump is provided on the pipeline connecting the water collection section and the water tank. By controlling the water pump to operate intermittently in a certain regular pattern, the method avoids excessive water accumulation in the water collection section from affecting normal drying, while simultaneously cooling the pipeline and the water tank, further reducing the temperature of the discharged circulating air.

[0010] To achieve the above objectives, a first aspect of the present invention provides a dryer condensation system, comprising a circulating air duct;

[0011] The cooling section is located inside the circulating air duct;

[0012] The water collection section is used to collect condensate generated by the cooling section.

[0013] The auxiliary air duct connects to the circulating air duct at one end from the front of the cooling section and to the water collection section at the other end, and is used to guide part of the circulating air into the water collection section.

[0014] The water collection section is connected to the outside of the dryer, and the circulating air is cooled by the water collection section and then discharged to the outside of the dryer.

[0015] In the above scheme, the auxiliary air duct diverts the circulating air with high humidity in the circulating air duct in front of the cooling section, and guides part of the circulating air with high humidity to the water collection section. The condensed water collected in the water collection section is discharged after condensation. This reduces the workload of the cooling section, improves the drying efficiency, and avoids the impact on the external environment of the dryer.

[0016] Furthermore, the dryer's condensation system also includes,

[0017] An axial flow fan is located at the end where the auxiliary air duct connects to the circulating air duct.

[0018] The above solution uses an axial flow fan to more effectively divert the circulating air in the circulating air duct, further reducing the workload of the cooling unit.

[0019] Furthermore, the dryer's condensation system also includes,

[0020] The filter section is located on the front side of the cooling section along the air outlet direction and is used to filter lint.

[0021] The auxiliary air duct guides the circulating air filtered by the filter section into the water collection section.

[0022] In the above scheme, the filter section is located in front of the cooling section along the air outlet direction in the circulating air duct, which can filter the lint. The auxiliary air duct guides the circulating air filtered by the filter section into the water collection section, avoiding the lint from entering and accumulating in the water collection section and affecting the smooth discharge of condensate and circulating air.

[0023] Furthermore, the dryer's condensation system also includes,

[0024] The lint collection section is located inside the circulating air duct, in front of the cooling section along the air outlet direction;

[0025] The filter section includes a first filter section located at the rear end of the lint collection section perpendicular to the air outlet direction, and a second filter section located on the lint collection section opposite to the position of the auxiliary air duct. The auxiliary air duct is connected to the lint collection section through the second filter section.

[0026] In the above scheme, the auxiliary air duct is directly connected to the lint collection section. Part of the circulating air passes through the first filter section and continues to circulate in the dryer's air duct. The other part of the circulating air is separated from the lint by the second filter section and enters the auxiliary air duct. This avoids lint from entering the water collection section and simplifies the overall structure of the circulating air duct.

[0027] Furthermore, the dryer's condensation system also includes,

[0028] The conduit connects the water collection section to the outside of the dryer and is used to guide the condensate water out.

[0029] The circulating air entering the water collection section is discharged to the outside of the dryer through a duct.

[0030] In the above solution, the water collection section is connected to the outside of the dryer through a conduit, which improves the flexibility of the water collection section's location and allows it to avoid interference with other internal structures of the dryer. This not only ensures the smooth exhaust of the circulating air for cooling but also optimizes and improves the space utilization within the dryer.

[0031] Specifically, the conduit can be directly connected to the outside of the dryer, or the conduit can be connected to the drain pipe of the dryer. When the conduit is connected to the drain pipe of the dryer, it can achieve cooling of the circulating air while avoiding incomplete cooling that could affect the external environment of the dryer.

[0032] Furthermore, the dryer's condensation system also includes,

[0033] The water tank, connected to the outside of the dryer, is used to store condensate.

[0034] The conduit connects the water collection section to the water tank. The circulating air is cooled by the water collection section and the water tank before being discharged to the outside of the dryer.

[0035] In the above solution, the conduit connects the water collection section and the water tank. When there is a lot of condensate collected in the water collection section, it can enter the water tank through the conduit, thus avoiding the impact of excessive condensate in the water collection section on the drying effect. At the same time, the circulating air entering the water collection section can also enter the water tank through the conduit and be discharged from the water tank. There is no need to add extra exhaust pipes and channels for circulating air in the dryer. The existing structure of the dryer can be used to smoothly achieve the discharge of circulating air, simplifying the structure of the dryer.

[0036] Furthermore, the conduit connects to the water collection section from the upper middle part.

[0037] The above solution avoids the water collection section being filled with condensate, which would prevent the circulating air from being discharged. It also avoids the situation where all the condensate in the water collection section is discharged during the condensate discharge process, thus preventing the circulating air from being effectively condensed.

[0038] A second aspect of the present invention provides a clothes dryer having the above-described condensation system.

[0039] Specifically, the cooling section is the evaporator of the heat pump system, the circulating air duct is located at the bottom of the dryer, the water tank is located at the top of the dryer, and the dryer also includes...

[0040] A water pump, connected to a conduit, is used to transport condensate from the collection section to the water tank;

[0041] A water level sensor is installed inside the water collection section to obtain water level information in the water collection section.

[0042] The above solution places the water tank at the top of the dryer, which can prevent the water in the water collection section from flowing out under gravity and failing to cool the circulating air. By obtaining the water level information in the water collection section through the water level sensor, it can prevent the water collection section from overflowing and causing the circulating air to be unable to be discharged smoothly. At the same time, it can also prevent excessive condensate from affecting the drying efficiency.

[0043] A third aspect of the present invention provides a control method for the above-mentioned dryer, specifically comprising the following steps:

[0044] S1. After the drying process begins, the axial flow fan continues to work, guiding some of the circulating air to the water collection section, where it is cooled by the water collection section and the water tank before being discharged.

[0045] S2. The drying process ends and the axial flow fan stops.

[0046] In the above scheme, the axial flow fan runs continuously during the drying process. In the early stage of drying, some of the hot and humid circulating air is condensed and discharged, which reduces the workload of the cooling section and improves the drying efficiency. In the later stage of drying, when the moisture content of the clothes is low, some of the circulating air is condensed and discharged, which can slightly reduce the temperature of the circulating air and protect the clothes from damage due to excessive temperature.

[0047] Furthermore, in step S1, the water level sensor acquires the water level information in the water collection section in real time. When the water level reaches the preset water level threshold, the computer board controls the water pump to run and send the condensate into the water tank.

[0048] The above solution avoids excessive condensate in the water collection section from affecting the discharge of circulating air. At the same time, the condensate is pumped into the water tank by a water pump, so that the condensate in the water collection section is always kept at a low temperature, which improves the condensation effect on the discharged circulating air. Meanwhile, the condensate enters the water tank through the duct, which can cool the duct and prevent the duct from overheating and reheating the circulating air, thus affecting the external environment of the dryer.

[0049] As an alternative to the above solution, the computer board controls the water pump to start at preset intervals to send condensate into the water tank.

[0050] Specifically, the dryer controls the water pump to start at the first interval, and the water pump continues to run for a second time before stopping; the above process is repeated until the drying is finished.

[0051] The above solution, by periodically draining the condensate in the water collection section, can prevent excessive condensate accumulation from affecting the exhaust of circulating air and drying efficiency, while also achieving periodic cooling of the duct, further improving the condensation effect of the circulating air exchange, and avoiding the impact on the external environment of the dryer caused by insufficient heat exchange of the circulating air.

[0052] The beneficial effects of this invention are as follows:

[0053] The circulating air entering the cooling section for condensation is diverted through an auxiliary air duct, reducing the workload of the cooling section and improving its condensation efficiency. A portion of the diverted circulating air enters the water collection section through the auxiliary air duct, where it exchanges heat with the collected condensate before being discharged outside the dryer. This prevents the high temperature and high moisture content of the circulating air from affecting the external environment of the dryer. The water collection section is connected to the water tank via a duct. Circulating air that undergoes primary heat exchange in the water collection section then enters the water tank for secondary heat exchange, further reducing the temperature of the circulating air discharged outside the dryer and further preventing... This design improves the user experience by minimizing the impact on the external environment of the dryer. The circulating air duct is located at the bottom of the dryer, while the water tank is located at the top. A water pump is connected to the duct. The water collection section exchanges heat with the circulating air, and the higher-temperature condensate is pumped to the water tank, ensuring that the condensate in the collection section remains at a lower temperature, thus improving the cooling effect on the circulating air. The water pump also cools the duct as it pumps the condensate from the collection section to the water tank, preventing damage from excessively high duct temperatures and avoiding the high-temperature duct heating the circulating air, which would affect the temperature of the circulating air discharged to the outside of the dryer.

[0061] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Those skilled in the art will understand that the following embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0063] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0064] This invention provides a condensation system for a clothes dryer, comprising:

[0065] Circulating air duct;

[0066] The cooling section is located inside the circulating air duct;

[0067] The water collection section is used to collect condensate generated by the cooling section.

[0068] The auxiliary air duct connects to the circulating air duct at one end from the front of the cooling section and to the water collection section at the other end, and is used to guide part of the circulating air into the water collection section.

[0069] The water collection section is connected to the outside of the dryer, and the circulating air is cooled by the water collection section and then discharged to the outside of the dryer.

[0070] The auxiliary air duct connects to the circulating air duct from the front of the cooling section, diverting the uncooled, hot and humid circulating air discharged from the drying drum. Some of the circulating air enters the water collection section through the auxiliary air duct, where it is cooled and dehumidified by the condensate collected in the water collection section before being discharged to the outside of the dryer. By diverting the airflow, the amount of circulating air entering the cooling section is reduced, thereby reducing the workload of the cooling section and eliminating the need for an additional separate cooling device. The dehumidified and cooled circulating air is discharged to avoid affecting the surrounding environment of the dryer, thus improving the user experience.

[0071] Furthermore, the present invention will be described and illustrated in more detail by way of specific embodiments.

[0072] Example 1

[0073] As an embodiment of the present invention, this embodiment provides a condensation system for a clothes dryer.

[0074] In this embodiment, as Figure 1 , 3 As shown, an axial flow fan 10 is provided at one end of the auxiliary air duct 3 that is connected to the circulating air duct 1. When the axial flow fan 10 rotates, it introduces the circulating air in the circulating air duct 1 into the auxiliary air duct 3. After being fully cooled by the condensate in the water collection section 4, the air is discharged to the outside of the dryer, which reduces the workload of the cooling section 2 and improves the drying effect of the dryer without increasing the energy consumption of the dryer.

[0075] Furthermore, the circulating air duct 1 is equipped with a filter section covering the cross section of the air duct. The connection between the auxiliary air duct 3 and the circulating air duct 1 is located on the air duct wall between the filter section and the cooling section 2. After the lint in the circulating air is filtered by the filter section, it enters the water collection section 4 through the auxiliary air duct 3 for condensation. This prevents the lint from entering the auxiliary air duct 3 or the water collection section 4, which would affect the normal discharge of condensate and circulating air. It also prevents the lint from being discharged to the outside of the dryer with the condensate or circulating air and affecting the external environment of the dryer.

[0076] Based on the above scheme, in order to improve the stability of the filter section, a lint collection section 5 is also provided in the circulating air duct 1. The filter section is provided on the lint collection section 5, including a first filter section 11 located at the rear end of the lint collection section 5 perpendicular to the air outlet direction, and a second filter section 12 located on the lint collection section 5 opposite to the auxiliary air duct 3. The circulating air filtered by the first filter section 11 is cooled by the cooling section 2 and then heated by the heating section 7 to dry the clothes again. The auxiliary air duct 3 guides the circulating air filtered by the second filter section 12 into the water collection section 4.

[0077] The above solution does not require significant modifications to the circulating air duct 1 and the lint collection unit 5, thus reducing production costs. Lint in the circulating air entering the lint collection unit 5 is filtered by the second filter unit 12 and remains in the lint collection unit 5, making it easier for users to clean up the lint.

[0078] Furthermore, the dryer's air duct also includes a conduit 6 that connects the water collection section 4 to the outside of the dryer and guides the condensate water out. The circulating air entering the water collection section 4 is discharged to the outside of the dryer through the conduit 6.

[0079] To save costs and simplify the design, the water collection part 4 is usually located below the cooling part 2 of the dryer. The fixed installation position may cause obstruction between the water collection part 4 and other devices inside the dryer. Therefore, the water collection part 4 is set to be connected to the outside of the dryer through the conduit 6. While adjusting the position of the water collection part 4, the connection between the water collection part 4 located in different positions and the outside of the dryer can be achieved simply by changing the length of the conduit 6 or changing the connection position of the conduit 6.

[0080] Specifically, duct 6 can directly pass through the dryer casing and connect to the outside of the dryer, and the cooled circulating air is directly discharged to the outside of the dryer through duct 6.

[0081] Alternatively, as an alternative to the above solution, duct 6 is connected to the dryer's drain pipe, and the circulating water and cooled circulating air are discharged to the outside of the dryer through the drain pipe, thus avoiding the circulating air from being discharged to the outside of the dryer without being sufficiently cooled, which would affect the external environment of the dryer.

[0082] Example 2

[0083] As another embodiment of the present invention, this embodiment is further improved based on Embodiment 1, specifically as follows:

[0084] In this embodiment, as Figure 2 As shown, the dryer's condenser system also includes,

[0085] Water tank 9, connected to the outside of the dryer, is used to store condensate;

[0086] The conduit 6 connects the water collection section 4 to the water tank 9. The circulating air is cooled by the water collection section 4 and the water tank 9 and then discharged to the outside of the dryer.

[0087] In the above scheme, the circulating air entering the water collection section 4 undergoes heat exchange and cooling in sequence within the water collection section 4 before entering the water tank 9. After secondary heat exchange in the water tank 9, it is discharged to the outside of the dryer, achieving sufficient cooling of the circulating air and preventing the high-temperature circulating air from affecting the ambient temperature when discharged to the outside of the dryer, thus improving the user experience. The cooling and discharge of the circulating air is achieved by using the condensate discharge and collection device inside the dryer, which does not require modification of the internal structure of the dryer, reducing production costs. At the same time, the water in the water tank 9 increases in temperature after heat exchange with the circulating air, reducing the power consumption required for heating during recycling and improving the energy-saving effect of the dryer.

[0088] Furthermore, the conduit 6 is connected to the water collection section 4 from the upper middle part of the water collection section 4.

[0089] The above solution avoids the water collection section 4 being filled with condensate, which would prevent the circulating air from being discharged. It also avoids the situation where all the condensate in the water collection section 4 is discharged during the condensate discharge process, thus preventing the circulating air from being effectively condensed.

[0090] The present invention also provides a clothes dryer having the above-mentioned condensation system, specifically:

[0091] Example 3

[0092] As another embodiment of the present invention, this embodiment provides a clothes dryer having the condensation system of Embodiment 2.

[0093] In this embodiment, as Figure 2 As shown, the circulating air duct 1 is located at the bottom of the dryer, and the water tank 9 is located at the top of the dryer. The water tank 9 is detachably connected to the dryer. The cooling section 2 is the evaporator of the heat pump system, and the heating section 7 is the condenser of the heat pump system. The dryer also includes…

[0094] Water pump 8, connected to conduit 6, is used to transport condensate from water collection section 4 to water tank 9.

[0095] In the above scheme, in order to facilitate the user's operation of the water tank 9, the water tank 9 is detachably installed on the top of the dryer. The condensate in the water collection part 4 is transported to the water tank 9 by the water pump 8, which can ensure that there is always a certain amount of condensate in the water collection part 4, and can achieve multiple heat exchange of the circulating air during the circulating air discharge process, thereby improving the heat exchange efficiency.

[0096] Furthermore, dryers also include,

[0097] A water level sensor is installed inside the water collection section 4 to obtain water level information in the water collection section 4.

[0098] The above solution can accurately obtain the water level information in the water collection section 4 through the water level sensor, thereby avoiding excessive condensation in the water collection section 4 that would prevent the circulating air from being discharged smoothly.

[0099] Furthermore, the present invention also provides a control method for the above-mentioned dryer, specifically as follows:

[0100] Example 4

[0101] As another embodiment of the present invention, this embodiment provides a control method for a clothes dryer as described in Embodiment 3.

[0102] Control methods such as Figure 5 As shown, the specific steps include the following:

[0103] S1. After the drying process begins, the axial flow fan 10 continues to work, guiding part of the circulating air to the water collection section 4, which is then cooled by the water collection section 4 and the water tank 9 before being discharged.

[0104] S2. The drying process ends, and the axial flow fan 10 stops.

[0105] In the above scheme, the axial flow fan 10 runs continuously during the drying process. In the early stage of drying, it reduces the workload of the cooling section 2 and improves the drying efficiency by condensing and discharging some of the hot and humid circulating air. In the later stage of drying, when the moisture content of the clothes is low, it can slightly reduce the temperature of the circulating air by condensing and discharging some of the circulating air, thus protecting the clothes from damage due to excessive temperature.

[0106] Furthermore, such as Figure 6As shown, in step S1, the water level sensor acquires the water level information in the water collection section 4 in real time. When the water level reaches the preset water level threshold, the computer board controls the water pump 8 to run and send the condensate into the water tank 9.

[0107] The above solution avoids excessive condensate in the water collection section 4 from affecting the discharge of circulating air. At the same time, the water pump 8 sends the condensate into the water tank 9, so that the condensate in the water collection section 4 always maintains a low temperature, which improves the condensation effect on the discharged circulating air. Meanwhile, the condensate enters the water tank 9 along the duct 6, which can cool the duct 6, prevent the duct 6 from overheating and being damaged, and also prevent the duct 6 from reheating the circulating air.

[0108] As an alternative to the above solution, the computer board controls the water pump 8 to start at preset intervals to send condensate into the water tank 9.

[0109] Specifically, the dryer controls the water pump 8 to start at the first interval, and the water pump 8 continues to run for a second time before stopping. This process is repeated until the drying is finished.

[0110] The above solution, by periodically draining the condensate in the water collection section 4, can prevent excessive accumulation of condensate in the water collection section 4 from affecting the discharge of circulating air and drying efficiency, while achieving periodic cooling of the duct 6, further improving the condensation effect of the circulating air exchange, and avoiding the impact on the external environment of the dryer caused by insufficient heat exchange of the circulating air.

[0111] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
