Description

Technical Field

[0001] This invention belongs to the field of drying equipment, and specifically relates to a water collection box for a clothes dryer, a condensation system for a clothes dryer, and a 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, while reducing the space required for drying clothes and improving people's quality of life. As a result, 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, application number CN202020040706.1 was submitted. A Chinese utility model patent discloses a heat pump dryer, including an air circulation system and a refrigerant system. The air circulation system includes a connected clothes drum and an air duct. The refrigerant system is located within the air duct and includes a water circulation system. The water circulation system includes a connected water collection tray, a water box, and an auxiliary cooler. The auxiliary cooler is located between the air outlet of the clothes drum and the refrigerant system. The auxiliary cooler has a bent-shaped extended channel. The condensate in the channel condenses the air in the air duct. The condensate circulates between the water collection tray, the water box, and the auxiliary cooler. The humid and hot air coming out of the air outlet of the clothes drum comes into contact with the auxiliary cooler, and the humid and hot air exchanges heat with the condensate in the channel to achieve condensation. Although the above solution achieves the condensation of the circulating air by the condensate during the drying process, the contact time between the auxiliary cooler and the circulating air is limited, and sufficient heat exchange cannot be achieved. Furthermore, the auxiliary cooler is located within the circulating air duct, which may affect the circulation efficiency of the circulating air, resulting in a decrease in the drying efficiency of the dryer.

[0005] To address this issue, existing technologies typically employ a spraying method to pre-cool the circulating air by injecting condensate into the circulating air duct. However, this condensate may remain within the circulating air duct, increasing the humidity of the circulating air and consequently reducing the drying efficiency of the dryer.

[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 dryer water collection box that addresses the problems in the prior art. By using partitions and guide plates to form a flow channel within the water collection box for condensing and cooling the circulating air, the contact time between the circulating air and the condensate is increased, thus achieving sufficient condensation of the circulating air.

[0008] Another objective of this invention is to provide a condensation system for a dryer with the aforementioned water collection box. By diverting the circulating air from the front of the condensation device, a portion of the circulating air is guided to the water collection box for condensation and cooling before being returned to the air duct for continued circulation. This reduces the workload of the condensation device and improves the drying efficiency.

[0009] Another object of the present invention is to provide a dryer having the above-mentioned condensation system, which uses condensate to condense the circulating air, thereby improving the condensation effect of the dryer without affecting its energy consumption.

[0010] To achieve the above objectives, a first aspect of the present invention provides a dryer water collection box, comprising, The box body has a first sidewall and a second sidewall that are disposed opposite to each other; A partition is provided inside the box body, connected to the first side wall, and extends from the first side wall to the second side wall. The extended end forms a communication opening with the second side wall, dividing the box body into a first chamber and a second chamber that are interconnected. The inlet connects the first chamber to the outside of the housing and is used to receive condensate. The air inlet connects the second chamber to the outside of the box body and is used to receive the circulating air from the dryer.

[0011] In the above scheme, the partition divides the water collection box into two interconnected chambers. The circulating air enters the second chamber from the air inlet and then enters the first chamber through the connecting port. During this period, it continuously exchanges heat with the condensate. The circulating air, after being fully condensed, is finally discharged from the water inlet, which prolongs the heat exchange time of the circulating air in the water collection box and improves the condensation effect of the circulating air.

[0012] Furthermore, in order to simplify the production cost of the water collection box, the first sidewall and the second sidewall are arranged parallel to each other.

[0013] Furthermore, the water collection box also includes a baffle plate, which is disposed in the second chamber to guide the circulating air entering the second chamber.

[0014] Furthermore, the guide plate includes: a first guide plate connected to the partition and extending from the partition into the second chamber; and a second guide plate disposed opposite to the first guide plate on a third side wall connected to the first and second side walls and extending from the third side wall into the second chamber. The first guide plate and the second guide plate are alternately arranged to form an S-shaped flow channel that connects the connecting port and the air inlet.

[0015] In the above scheme, the first guide plate and the second guide plate are alternately arranged to form an S-shaped flow channel that connects the connecting port and the air inlet, which further increases the residence time of the circulating air in the water collection box and improves the condensation effect of the water collection box on the circulating air.

[0016] Furthermore, in order to reduce the manufacturing cost and difficulty of the water collection box, the baffle is set to be parallel to the third side wall, and the first guide plate and the second guide plate are parallel to each other. The above arrangement makes the circulating air passing through the flow channel more uniform, improves the efficiency of the water collection box in condensing the circulating air, and avoids the generation of eddies in the flow channel, which would reduce the condensation efficiency.

[0017] A second aspect of the present invention provides a condensation system for a dryer having the above-mentioned dryer water collection box, comprising a circulating air duct; A condensation device is installed inside the circulating air duct to condense the circulating air; The air guide section has one end connected to the circulating air duct from the front side of the cooling section, and is used to split the circulating air. The water inlet of the water collection box is connected to the inside of the circulating air duct to receive the condensate generated by the condensation device during the drying process. The air inlet is connected to the other end of the air guide section.

[0018] In the above scheme, the water collection box collects the condensate generated by the condenser during the drying process. The circulating air is diverted by the air guide and enters the water collection box. After being condensed by the condensate, it returns to the circulating air duct from the water inlet to continue circulating, which reduces the condensation load of the condenser and improves the drying efficiency of the dryer.

[0019] Furthermore, the first chamber of the water collection box is located at the lower part of the circulating air duct, and the water inlet is located at the top of the water collection box, opposite to the position of the condensation device.

[0020] The above solution achieves air diversion and condensation while reducing the need for adjustments to the original structure of the dryer. Compared with the existing dryer structure, this solution only adds an air guide section, which makes little change to the overall structure of the dryer and reduces production costs.

[0021] Furthermore, the air guide section includes an axial flow fan located at the end of the air guide section that connects to the circulating air duct, for guiding the circulating air into the air guide section.

[0022] The above solution uses an axial flow fan to enable the air guide section to stably divert the circulating air, avoiding the air volume affecting the diversion effect of the air guide section, thus improving stability.

[0023] Furthermore, the air guide section also includes a blocking section, which extends from the end of the air guide section that communicates with the circulating air duct into the circulating air duct and is located on the side close to the condensation device.

[0024] In the above scheme, the blocking part can reduce the flow velocity of the circulating air passing through the end of the air guide, thereby making the circulating air volume entering the air guide more stable and further improving the air guide's diversion effect on the circulating air.

[0025] Furthermore, the air guide section also includes a guide section extending from one end of the air guide section that communicates with the air inlet into the water collection box, located on the side close to the first chamber.

[0026] In the above scheme, the guide part is located on the side close to the first chamber. Due to the obstruction of the guide part, the circulating air can enter the second chamber more smoothly when entering the water collection box, avoiding the circulating air from not being able to enter the second chamber smoothly and returning to the circulating air duct from the water inlet of the first chamber, which would affect the drying efficiency.

[0027] Furthermore, the dryer's condensation system also includes, The filter section is located in front of the condenser along the air outlet direction of the circulating air duct; The air guide section splits the circulating air that has been filtered by the filter section.

[0028] In the above scheme, when the circulating air passes through the filter section, the lint it carries is blocked and separated from the circulating air by the filter section. The air guide section diverts the circulating air that has passed through the filter section, preventing the circulating air with lint from entering the water collection box. The accumulation of lint in the water collection box may reduce the amount of condensate in the water collection box, affecting the condensation effect on the circulating air.

[0029] A third aspect of the present invention provides a clothes dryer having the above-described condensation system.

[0030] The beneficial effects of this invention are as follows: 1. The water collection box is divided into a first chamber and a second chamber that are interconnected by a partition. After the circulating air enters the second chamber through the air inlet, it reaches the first chamber through the connecting port and is discharged from the water inlet of the first chamber. This prolongs the heat exchange time between the condensate and the circulating air and improves the condensation effect of the circulating air.

[0031] 2. A baffle plate is installed in the second chamber, which further extends the residence time of condensate in the second chamber and further improves the condensation effect on the circulating air.

[0032] 3. The water inlet of the water collection box is connected to the circulating air duct and is located below the circulating air duct and opposite the position of the condenser. The circulating air cooled by the water collection box can directly return to the circulating air duct through the water inlet to continue circulating, which reduces the workload of the condenser and improves the drying efficiency of the dryer.

[0033] 4. An axial flow fan and a blocking part are installed at one end of the air guide section that connects to the circulating air duct. The cooperation between the axial flow fan and the blocking part improves the air guide section's diversion effect on the circulating air, further improving the drying efficiency.

[0040] 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.

[0041] In the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. 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 utility model according to the specific circumstances.

[0042] 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 utility model 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 the invention. Example 1

[0043] As an embodiment of the present invention, this embodiment provides a dryer water collection box, as shown in Figures 4 and 5, including: a box body, including a first side wall 401 and a second side wall 402 disposed opposite to each other; a partition 45 disposed inside the box body, extending from the first side wall 401 to the second side wall 402, the extended end forming a communication opening with the second side wall 402, dividing the box body into two interconnected chambers 41. The inlet 43 connects the first chamber 41 to the outside of the box body and is used to receive condensate. The air inlet connects the second chamber 42 to the outside of the box body and is used to receive the circulating air from the dryer.

[0044] Condensate enters the water collection box 4 through the inlet 43. Since the first chamber 41 and the second chamber 42 are connected by a connecting port, both the first chamber 41 and the second chamber 42 contain condensate. After the circulating air enters the water collection box 4 through the air inlet, it first exchanges heat with the condensate in the second chamber 42, then enters the first chamber 41 through the connecting port, and finally exits from the inlet 43 on the first chamber 41. The above scheme divides the water collection box 4 into the first chamber 41 and the second chamber 42 by the partition 45, which prolongs the residence time of the circulating air in the water collection box 4. The circulating air that has undergone the above process can be fully condensed and cooled.

[0045] To further increase the residence time of the circulating air in the water collection box 4, the air inlet is set away from the connection port, allowing the circulating air to stay in the water collection box 4 for a longer period of time.

[0046] The above solution improves the condensation effect of the water collection box 4 on the circulating air by increasing the residence time of the circulating air in the water collection box 4. Example 2

[0047] As another embodiment of the present invention, this embodiment makes further improvements based on Embodiment 1. Specifically as follows: In this embodiment, as shown in FIG4, a guide plate is also provided in the second chamber 42. The guide plate can guide the circulating air entering the water collection box 4. Under the guidance of the guide plate, the circulating air can stay in the second chamber 42 for a longer time, thereby enabling sufficient heat exchange with the condensate, so that the circulating air condensed by the water collection box 4 has a lower temperature.

[0048] To improve the guiding effect of the deflector on the circulating air, a first deflector 46 and a second deflector 47 are provided in the second chamber 42. The first deflector 46 is connected to the partition 45 and extends from the partition 45 into the second chamber 42. The second deflector 47 is provided opposite to the first deflector 46 on the third side wall 403, which is connected to the first side wall 401 and the second side wall 402, and extends from the third side wall 403 into the second chamber 42. The first deflector 46 and the second deflector 47 are alternately arranged.

[0049] The first guide plate 46 and the second guide plate 47 are alternately arranged to form an S-shaped flow channel in the second chamber 42 that connects the air inlet and the connecting port. As the circulating air moves along the S-shaped flow channel, it can fully contact the condensate in the second chamber 42, which further improves the condensation effect of the water collection box 4 on the circulating air.

[0050] In the above scheme, in order to improve the stability of the circulating air volume in the water collection box 4 and improve the heat exchange efficiency, the first guide plate 46 and the second guide plate 47 are arranged in parallel to each other. This avoids the influence of the uneven width of the flow channel on the uniformity of the circulating air entering the flow channel, and improves the efficiency of the water collection box 4 in condensing the circulating air. At the same time, the arrangement of the guide plates in the water collection box 4 in the above scheme is more regular, which facilitates manufacturing and reduces the difficulty and cost of production.

[0051] The present invention also provides a dryer condensation system having the water collection box described in the above embodiments, specifically: Example 3

[0052] As another embodiment of the present invention, this embodiment provides a clothes dryer having a water collection box as described in Embodiment 2.

[0053] In this embodiment, as shown in FIG1, the clothes dryer includes, Circulating air duct 1; A condensing device 2 is installed inside the circulating air duct 1 to condense the circulating air; The air guide section 3 has one end connected to the circulating air duct 1 from the front side of the cooling section, and is used to split the circulating air; The inlet 43 of the water collection box 4 is connected to the inside of the circulating air duct 1 to receive the condensate generated by the condensation device during the drying process; The air inlet 44 is connected to the other end of the air guide 3.

[0054] In the above scheme, the water inlet 43 of the water collection box 4 collects the condensate generated by the condenser 2 during the drying process. The air inlet 44 is connected to the air guide 3. Part of the circulating air diverted by the air guide 3 enters the water collection box 4 for condensation. After condensation, it returns to the circulating air duct 1 from the water inlet 43. While reducing the workload of the condenser 2, it does not affect the total air volume in the circulating air duct 1, and the drying efficiency will not be reduced due to the reduction of the total air volume in the circulating air duct 1.

[0055] Furthermore, as shown in Figure 5, in order to simplify the structure of the condensation system of the dryer, the first chamber 41 of the water collection box 4 is located at the lower part of the circulation duct 1, and the water inlet 43 is located at the top of the water collection box 4 and connected to the circulation duct 1. There is no need to add a pipeline connecting the circulation duct 1 and the water inlet 43 on the water collection box 4, thus avoiding significant changes to the structure of the dryer that would reduce the utilization rate of the internal space of the dryer.

[0056] Furthermore, the first chamber 41 of the water collection box 4 coincides with the condenser 2, and the water inlet 43 is located at the top of the water collection box 4 opposite to the condenser 2. Since the circulating air returning to the circulation duct 1 from the water inlet 43 has a lower temperature, and the water inlet 43 and the condenser 2 are opposite each other, the circulating air returning to the circulation duct 1 from the water inlet 43 can assist the condenser 2 in cooling the part of the circulating air that does not enter the water collection box 4, further reducing the workload of the condenser 2. Example 4

[0057] As another embodiment of the present invention, this embodiment is further improved based on embodiment three, specifically as follows: In this embodiment, as shown in FIG2, an axial flow fan 31 is provided at the end of the air guide section 3 that is connected to the circulating air duct 1. The axial flow fan 31 can increase the air volume of the circulating air entering the air guide section 3, improve the air diversion effect of the air guide section 3 on the circulating air, reduce the amount of circulating air directly condensed by the condenser 2, thereby reducing the workload of the condenser 2 and improving the drying efficiency of the dryer. At the same time, it also improves the stability of the air diversion of the circulating air by the air guide section 3, avoids the diversion effect being affected by the air volume, and improves stability.

[0058] Furthermore, as shown in Figure 3, a blocking part 32 is provided at the end of the air guide 3 that is connected to the circulating air duct 1. The blocking part 32 extends into the circulating air duct 1 from the end of the air guide 3 that is connected to the circulating air duct 1 and is located on the side close to the condenser 2.

[0059] In the above scheme, the blocking part 32 can reduce the flow velocity of the circulating air passing through the end of the air guide part 3, thereby making the circulating air volume entering the air guide part 3 more stable and further improving the diversion effect of the air guide part 3 on the circulating air.

[0060] As shown in Figure 1, to prevent the circulating air guided to the water collection box 4 by the air guide 3 from bypassing the second chamber 42 and returning directly to the inside of the circulating air duct 1 from the water inlet 43, a guide part 33 extending into the inside of the water collection box 4 is provided at the end of the air guide 3 that connects to the air inlet 44 of the water collection box 4. The guide part 33 is located on the side close to the first chamber 41. After the circulating air enters the water collection box 4, it will not directly enter the first chamber 41 due to the obstruction of the guide part 33, thereby improving the stability of the water collection box 4 in condensing the circulating air duct 1.

[0061] Furthermore, the condensation system of the dryer also includes a filter section 5, which is located in front of the condensation device 2 along the air outlet direction of the circulating air duct 1; the air guide section 3 diverts the circulating air filtered by the filter section 5.

[0062] In the above scheme, when the circulating air passes through the filter section 5, the lint it carries is blocked and separated from the circulating air by the filter section 5. The air guide section 3 diverts the circulating air filtered by the filter section 5, preventing the circulating air with lint from entering the water collection box 4. The accumulation of lint in the water collection box 4 may reduce the amount of condensate in the water collection box 4, affecting the condensation effect on the circulating air.

[0063] The present invention also provides a clothes dryer having the condensation system described in the above embodiments, specifically: Example 5

[0064] As another embodiment of the present invention, this embodiment provides a clothes dryer having a condensation system as described in Embodiment 4.

[0065] Specifically, after the dryer starts the drying process, the axial flow fan 31 starts and continuously diverts the circulating air. The diverted circulating air enters the water collection section and is condensed by the condensate. Then, it returns to the circulating air duct 1 through the water inlet 43 to continue circulating. This reduces the workload of the condenser 2 while improving the drying efficiency of the dryer. Furthermore, the water collection box 4 is connected to the dryer's drain pipe and is equipped with a water level sensor. The water level in the water collection box 4 is monitored in real time by the water level sensor. When the water level is high, some condensate is discharged through the drain pipe to prevent excessive condensate from hindering the condensation of the circulating air.

[0066] Furthermore, in order to improve the condensation effect of the water collection box 4 on the circulating air, the water inlet 43 of the water collection box 4 can also be connected to the water inlet pipe to replenish the water collection box 4 with condensate when there is little condensate, so as to achieve normal condensation of the circulating air.

[0067] The above solution maintains the condensation capacity of the water collection box 4 while allowing the condensate in the water collection box 4 to be renewed through the water inlet pipe and the water outlet pipe. This enables the water collection box 4 to continuously condense the circulating air and avoids the water temperature from becoming too high due to the condensate not being replaced for a long time, which would prevent the circulating air from being condensed.

[0068] Alternatively, as an alternative to the above solution, the water collection box 4 is connected to the water tank via a water pump. When there is too much condensate, or when the condensate is stored in the water collection box 4 for too long, the water pump sends the condensate into the water tank, and then the water collection box 4 is replenished with condensate through the water inlet pipe to achieve continuous condensation of the circulating air.

[0069] 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.
