- A liquid-discharging
partition 10 for adryer 100 and thedryer 100 according to embodiments of the present disclosure are described below with reference to the drawings. For example, thedryer 100 may be a heat pump dryer. - As illustrated in
FIG. 1 andFIG. 2 , according to the liquid-dischargingpartition 10 of thedryer 100 of the embodiments of the present disclosure, the liquid-dischargingpartition 10 has aliquid guide groove 21. Theliquid guide groove 21 has aninlet 211 and anoutlet 212. Theinlet 211 and theoutlet 212 are located at two ends of theliquid guide groove 21 in a length direction (referring to a direction F1 illustrated inFIG. 2 ) of theliquid guide groove 21, respectively. It should be noted that, as illustrated inFIG. 4 , theinlet 211 of theliquid guide groove 21 is in communication with an air duct of thedryer 100. Anevaporator 30 of thedryer 100 is located within the air duct. A condensed fluid on theevaporator 30 can flow into theliquid guide groove 21 through theinlet 211 of theliquid guide groove 21, and is finally discharged through theoutlet 212 of theliquid guide groove 21. For example, theoutlet 212 of theliquid guide groove 21 is in communication with awater storage portion 50 of thedryer 100. Thewater storage portion 50 is configured to store the condensed liquid flowing to thewater storage portion 50 from theliquid guide groove 21. - The liquid-discharging
partition 10 further has adiffluent groove 31 defined on at least one side of theliquid guide groove 21 in a width direction of the liquid guide groove 21 (refer to a direction F2 illustrated inFIG. 2 ). In other words, thediffluent groove 31 may be located on one side of theliquid guide groove 21 in the width direction of theliquid guide groove 21, or thediffluent groove 31 may be located on each of two sides of theliquid guide groove 21 in the width direction of theliquid guide groove 21. Thediffluent groove 31 is in communication with theliquid guide groove 21 through liquid passingopenings 22. For example, as illustrated inFIG. 2 , thediffluent groove 31 may be formed in a trapezoidal shape. - It should be noted that the inventor found in actual researches that in the related art, the heat pump dryer has the liquid-discharging partition provided on a base thereof. The liquid-discharging partition separates an air duct and a water channel at a condenser and an evaporator. However, when a negative pressure is generated in the air duct, that is, an external air pressure is greater than an air pressure inside the air duct, the condensed fluid collected in the water storage portion of the dryer will flow back to the air duct along the water channel through the inlet of the liquid guide groove, affecting a drying efficiency of the dryer.
- In the present disclosure, when the negative pressure is generated in the air duct, the condensed fluid flowing back from the
water storage portion 50 flows to the outlet of theliquid guide groove 21, and flows into theliquid guide groove 21 and thediffluent groove 31 respectively after passing through the outlet of theliquid guide groove 21. In this way, by arranging theliquid guide groove 21 and thediffluent groove 31 that are in communication with each other, on one hand, a diffluent effect can be achieved to reduce a hydraulic pressure, and on the other hand, a path for a back flow of the condensed fluid is increased, which is beneficial to preventing the condensed fluid from flowing back into the air duct through the inlet of theliquid guide groove 21. - Accordingly, according to the liquid-discharging
partition 10 for thedryer 100 disclosed by the embodiments of the present disclosure, theliquid guide groove 21 and thediffluent groove 31 are in communication with each other. In this way, when the negative pressure is generated in the air duct, the condensed fluid flowing back to theoutlet 212 of theliquid guide groove 21 can flow to theliquid guide groove 21 and thediffluent groove 31 respectively. Therefore, on one hand, a diffluent effect can be achieved to reduce a hydraulic pressure, and on the other hand, a path for a back flow of the condensed fluid is increased, which is beneficial to preventing the condensed fluid from flowing back into the air duct. - In some embodiments of the present disclosure, as illustrated in
FIG. 2 , at least two liquid passingopenings 22 are provided. One of the at least two liquid passingopenings 22 is formed as the inlet of thediffluent groove 31 and another one of the at least two liquid passing openings is formed as the outlet of thediffluent groove 31. Therefore, thediffluent groove 31 has an inlet and an outlet that are in communication with theliquid guide groove 21, which facilitates the condensed fluid in theliquid guide groove 21 to flow into and flow out of thediffluent groove 31, and is beneficial to improving a diffluent efficiency of thediffluent groove 31. - For example, as illustrated in
FIG. 2 , two liquid passingopenings 22 are provided and spaced apart from each other in a length direction of theliquid guide groove 21. Theliquid passing opening 22 approximate to theinlet 211 of theliquid guide groove 21 is an inlet of thediffluent groove 31, and theliquid passing opening 22 distal to theinlet 211 of theliquid guide groove 21 is an outlet of thediffluent groove 31. - In some embodiments of the present disclosure, referring to
FIG. 2 , a plurality of liquid passingopenings 22 is provided and spaced apart from one another in the length direction of theliquid guide groove 21 and is each in communication with thediffluent groove 31. This facilitates the flowing of the condensed fluid in theliquid guide groove 21 into or out of thediffluent groove 31, and is advantageous in improving the diffluent efficiency of thediffluent groove 31. Of course, the present disclosure is not limited to this, and only oneliquid passing opening 22 may be provided. - In some embodiments of the present disclosure, as illustrated in
FIG. 1 , the liquid-dischargingpartition 10 includes aplate body 1, aliquid guide portion 2, and adiffluent portion 3. Theliquid guide portion 2 is arranged on a side surface of theplate body 1. Theliquid guide groove 21 is defined between theliquid guide portion 2 and theplate body 1. Thediffluent portion 3 is arranged on a side surface of theplate body 1. Thediffluent groove 31 is defined by theplate body 1 and thediffluent portion 3; and/or thediffluent groove 31 is defined by theplate body 1, theliquid guide portion 2, and thediffluent portion 3. - For example, as illustrated in
FIG. 1 andFIG. 2 , theliquid guiding portion 2 arranged on a side surface of theplate body 1, and theliquid guide groove 21 is defined by theliquid guiding portion 2 and theplate body 1. Thediffluent portion 3 is arranged on a side surface of theplate body 1, and thediffluent groove 31 is defined by theplate body 1, theliquid guide portion 2, and thediffluent portion 3. Thediffluent groove 31 is in communication with theliquid guide groove 21 through two liquid passingopenings 22. - In some embodiments of the present disclosure, as illustrated in
FIG. 1 andFIG. 2 , the liquid-dischargingpartition 10 further includes a firstliquid retaining rib 4 arranged on theplate body 1, located within thediffluent groove 31, and spaced apart from theliquid guide portion 2. It can be understood that the arrangement of the firstliquid retaining rib 4 in thediffluent groove 31 is beneficial to increasing a resistance to the back flowing of the condensed fluid when a negative pressure is generated in the air duct, and therefore is beneficial to preventing the condensed fluid from flowing back into the air duct. - In some embodiments of the present disclosure, as illustrated in
FIG. 1 andFIG. 2 , the liquid-dischargingpartition 10 further includes a secondliquid retaining rib 5 arranged on theplate body 1, located within thediffluent groove 31, and spaced apart from theliquid guide portion 2. The secondliquid retaining rib 5 is connected to the firstliquid retaining rib 4. An extending direction of the secondliquid retaining rib 5 is not parallel to an extending direction of the firstliquid retaining rib 4. It can be understood that by a cross arrangement of the firstliquid retaining rib 4 and the secondliquid retaining rib 5, the path for the back flow of the condensed fluid is further increased, the resistance to the back flowing of the condensed fluid is increased at the same time. Besides, the structure is simple, and is convenient for processing and forming. - Further, as illustrated in
FIG. 1 , a plurality ofliquid guide ribs 4 is provided and spaced apart from one another. Every two adjacent firstliquid retaining ribs 4 are connected to each other by a secondliquid retaining rib 5. Here, a plurality refers to two or more. It can be understood that the firstliquid retaining ribs 4 and the secondliquid retaining ribs 5 are in a cross arrangement, and every two adjacent firstliquid retaining ribs 4 are connected by the secondliquid retaining rib 5. In this way, it is beneficial to further increasing the path for the back flow of the condensed fluid while increasing the resistance to the back flowing of the condensed fluid. - In some embodiments of the present disclosure, as illustrated in
FIG. 1 andFIG. 2 , on a plane parallel to theplate body 1, at least one of an extending direction of the firstliquid retaining rib 4 or an extending direction of the secondliquid retaining rib 5 is not parallel to the length direction of theliquid guide groove 21. For example, neither the extending direction of the firstliquid retaining rib 4 nor the extending direction of the secondliquid retaining rib 5 is parallel to the length direction of theliquid guide groove 21. Therefore, when the negative pressure is generated in the air duct, the resistance of the firstliquid retaining rib 4 and the secondliquid retaining rib 5 to the back flowing of the condensed fluid can be further increased. - Further, as illustrated in
FIG. 1 , the liquid-dischargingpartition 10 further includes a thirdliquid retaining rib 6 arranged on theplate body 1 and located within thediffluent groove 31. The thirdliquid retaining rib 6 is parallel to the firstliquid retaining rib 4. The thirdliquid retaining rib 6 is located between two adjacent firstliquid retaining ribs 4 and spaced apart from the secondliquid retaining rib 5. Therefore, the firstliquid retaining rib 4, the secondliquid retaining rib 5, and the thirdliquid retaining rib 6 form a labyrinth-shaped structure, which greatly increases the path for the back flow of the condensed fluid while increasing the resistance to the back flowing with a simple structure and low cost. For example, as illustrated inFIG. 1 , a plurality of thirdliquid retaining ribs 6 may be provided, and the plurality of thirdliquid retaining ribs 6 are arranged in parallel and spaced apart from each other. - In some embodiments of the present disclosure, referring to
FIG. 2 , theliquid guide groove 21 has afirst side wall 213 and asecond side wall 214 that are opposite to each other. For example, as illustrated inFIG. 2 , thefirst side wall 213 and thesecond side wall 214 are defined by inner side walls of theliquid guide portion 2 that are opposite to each other in the F2 direction. At least one of thefirst side wall 213 or thesecond side wall 214 has aliquid guide rib 7 provided on an inner surface thereof. Theliquid guide rib 7 on one of thefirst side wall 213 and thesecond side wall 214 extends obliquely towards the other of thefirst side wall 213 and thesecond side wall 214. In other words, only one of thefirst side wall 213 and thesecond side wall 214 has aliquid guide rib 7 provided on an inner surface thereof, and theliquid guide rib 7 extends obliquely towards the other of thefirst side wall 213 and thesecond side wall 214. Alternatively, as illustrated inFIG. 2 , each of thefirst side wall 213 and thesecond side wall 214 has aliquid guide rib 7 provided on an inner surface thereof, and theliquid guide rib 7 on either one of thefirst side wall 213 and thesecond side wall 214 extends obliquely towards the other of thefirst side wall 213 and thesecond side wall 214. In this way, the provision of theliquid guide rib 7 is beneficial for increasing the resistance to the flowing of the condensed fluid in theliquid guide groove 21 and preventing the back flowing of the condensed fluid, when the negative pressure is generated in the air duct. - In some examples, as illustrated in
FIG. 2 , theliquid guide rib 7 extends obliquely towards theoutlet 212 of theliquid guide groove 21 from outside to inside in the width direction of theliquid guide groove 21. In the F2 direction, a direction approaching thefirst side wall 213 and a direction approaching thesecond side wall 214 is "outside", and a direction approaching a center of theliquid guide groove 21 is "inside". It can be understood that, during the collection of the condensed fluid, theliquid guide rib 7 can play a role in guiding water, and when the negative pressure is generated and the back flowing is caused, theliquid guide rib 7 increases the resistance to the back flowing of the condensed fluid and can prevent the condensed fluid from flowing back to the air duct. - In some embodiments of the present disclosure, referring to
FIG. 2 , a plurality ofliquid guide ribs 7 is provided and spaced apart from one another in the length direction of theliquid guide groove 21. Therefore, by the arrangement of the plurality ofliquid guide ribs 7 spaced apart from one another, when the negative pressure is generated and the back flowing is caused, the resistance to the back flowing of the condensed fluid is further increased to prevent the condensed fluid from flowing back to the air duct. - Further, as illustrated in
FIG. 2 , the plurality ofliquid guide ribs 7 includes a firstliquid guide rib 71 and a secondliquid guide rib 72. The firstliquid guide rib 71 has an end connected to thefirst side wall 213, and another end extending obliquely towards theoutlet 212 of theliquid guide groove 21 and spaced apart from thesecond side wall 214. The secondliquid guide rib 72 has an end connected to thesecond side wall 214, and another end extending obliquely towards theoutlet 212 of theliquid guide groove 21 and spaced apart from thefirst side wall 213. It can be understood that, by the arrangement of the firstliquid guide rib 71 and the secondliquid guide rib 72 that are spaced apart from each other, during the collection of the condensed fluid, the firstliquid guide rib 71 and the secondliquid guide rib 72 can play a good role in guiding water, and when the negative pressure is generated and the back flowing is caused, the firstliquid guide rib 71 and the secondliquid guide rib 72 can further increase the resistance to the back flowing of the condensed fluid, which is beneficial to preventing the condensed fluid from flowing back to the air duct. - In some embodiments of the present disclosure, the plurality of
liquid guide ribs 7 includes a plurality of firstliquid guide ribs 71 and a plurality of secondliquid guide ribs 72. The plurality of firstliquid guide ribs 71 and the plurality of secondliquid guide ribs 72 are arranged alternately and spaced apart from each other in the length direction of theliquid guide groove 21. Therefore, when the negative pressure is generated and the back flowing is caused, the resistance to the back flowing of the condensed fluid can be greatly increased to prevent the condensed fluid from flowing back to the air duct. The structure is simple and the production cost is low. - In some embodiments of the present disclosure, the
liquid passing opening 22 is defined in one of thefirst side wall 213 and thesecond side wall 214 closer to thediffluent portion 3. Therefore, the structure is simple, and is beneficial to the processing and forming of the liquid-dischargingpartition 10. - In some embodiments of the present disclosure, the
liquid guiding portion 2 and thediffluent portion 3 are each a flexible member. For example, theliquid guide portion 2 and thediffluent portion 3 are each a silicone member or a rubber member. In this way, a sealing performance between the liquid-dischargingpartition 10 and an inner bottom wall of anair duct housing 20 can be enhanced, which is beneficial to preventing the condensed fluid from flowing into the air duct through gaps between theliquid guide portion 2, thediffluent portion 3, and theair duct housing 20, and is beneficial to improving the drying efficiency. - In some embodiments of the present disclosure, the first
liquid retaining rib 4, the secondliquid retaining rib 5, the thirdliquid retaining rib 6, and theliquid guide rib 7 are each a flexible member. For example, the firstliquid retaining rib 4, the secondliquid retaining rib 5, the thirdliquid retaining rib 6, and theliquid guide rib 7 are each a silicone member or a rubber member. - Referring to

A liquid-discharging channel a is defined between an inner bottom wall of thechamber 201 and each of theliquid guide groove 21 and thediffluent groove 31. - For example, as illustrated in
FIG. 3 andFIG. 4 , each of theevaporator 30 and thecondenser 40 is arranged on the liquid-dischargingpartition 10 and can play a role in pressing the liquid-dischargingpartition 10 tight. Thechamber 201 has awater guide groove 202 provided on the inner bottom wall thereof. Theevaporator 30 is arranged on thewater guide groove 202, and thewater guide groove 202 is in communication with theinlet 211 of theliquid guide groove 21. When thedryer 100 operates normally, i.e., the negative pressure is not generated in the air duct, the condensed fluid on theevaporator 30 can flow downwards into thewater guide groove 202, then flow into theliquid guide groove 21 and thediffluent groove 31 through theinlet 211 of theliquid guide groove 21, and finally be discharged through theoutlet 212 of theliquid guide groove 21. - When the negative pressure is generated in the air duct, the condensed fluid flowing back from the
water storage portion 50 flows to theoutlet 212 of theliquid guide groove 21, and flows into theliquid guide groove 21 and thediffluent groove 31 after passing through theoutlet 212 of theliquid guide groove 21. By the provision of theliquid guide groove 21 and thediffluent groove 31 which are in communication with each other, on one hand, a diffluent effect can be achieved to reduce a hydraulic pressure, and on the other hand, the path for the back flow of the condensed fluid is increased, which is beneficial to preventing the condensed fluid from flowing back into the air duct through the inlet of theliquid guide groove 21. - According to the
