In order to simplify the description of the present disclosure, components and arrangements of specific examples are described herein. Of course, these specific examples are merely for the purpose of illustration, and they are not intended to limit the present disclosure. Furthermore, the same reference numerals and/or reference letters may appear in different examples of the present disclosure for the purpose of simplicity and clarity, instead of indicating a relationship between different discussed embodiments and/or arrangements. In addition, the present disclosure provides examples of various specific processes and materials. However, applications of other processes and/or the use of other materials are conceivable for those skilled in the art.
A liquid-discharging partition 10 for a dryer 100 and the dryer 100 according to embodiments of the present disclosure are described below with reference to the drawings. For example, the dryer 100 may be a heat pump dryer.
As illustrated in FIG. 1 and FIG. 2, according to the liquid-discharging partition 10 of the dryer 100, the liquid-discharging partition 10 has a liquid guide groove 21. The liquid guide groove 21 has an inlet 211 and an outlet 212. The inlet 211 and the outlet 212 are located at two ends of the liquid guide groove 21 in a length direction (referring to a direction F1 illustrated in FIG. 2) of the liquid guide groove 21, respectively. It should be noted that, as illustrated in FIG. 4, the inlet 211 of the liquid guide groove 21 is in communication with an air duct of the dryer 100. An evaporator 30 of the dryer 100 is located within the air duct. A condensed fluid on the evaporator 30 can flow into the liquid guide groove 21 through the inlet 211 of the liquid guide groove 21, and is finally discharged through the outlet 212 of the liquid guide groove 21. For example, the outlet 212 of the liquid guide groove 21 is in communication with a water storage portion 50 of the dryer 100. The water storage portion 50 is configured to store the condensed liquid flowing to the water storage portion 50 from the liquid guide groove 21.
The liquid-discharging partition 10 further has a diffluent groove 31 defined on at least one side of the liquid guide groove 21 in a width direction of the liquid guide groove 21 (refer to a direction F2 illustrated in FIG. 2). In other words, the diffluent groove 31 may be located on one side of the liquid guide groove 21 in the width direction of the liquid guide groove 21, or the diffluent groove 31 may be located on each of two sides of the liquid guide groove 21 in the width direction of the liquid guide groove 21. The diffluent groove 31 is in communication with the liquid guide groove 21 through liquid passing openings 22. For example, as illustrated in FIG. 2, the diffluent 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 the liquid guide groove 21, and flows into the liquid guide groove 21 and the diffluent groove 31 respectively after passing through the outlet of the liquid guide groove 21. In this way, by arranging the liquid guide groove 21 and the diffluent 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 the liquid guide groove 21.
Accordingly, according to the liquid-discharging partition 10 for the dryer 100, the liquid guide groove 21 and the diffluent 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 the outlet 212 of the liquid guide groove 21 can flow to the liquid guide groove 21 and the diffluent 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 passing openings 22 are provided. One of the at least two liquid passing openings 22 is formed as the inlet of the diffluent groove 31 and another one of the at least two liquid passing openings is formed as the outlet of the diffluent groove 31. Therefore, the diffluent groove 31 has an inlet and an outlet that are in communication with the liquid guide groove 21, which facilitates the condensed fluid in the liquid guide groove 21 to flow into and flow out of the diffluent groove 31, and is beneficial to improving a diffluent efficiency of the diffluent groove 31.
For example, as illustrated in FIG. 2, two liquid passing openings 22 are provided and spaced apart from each other in a length direction of the liquid guide groove 21. The liquid passing opening 22 approximate to the inlet 211 of the liquid guide groove 21 is an inlet of the diffluent groove 31, and the liquid passing opening 22 distal to the inlet 211 of the liquid guide groove 21 is an outlet of the diffluent groove 31.
In some embodiments of the present disclosure, referring to FIG. 2, a plurality of liquid passing openings 22 is provided and spaced apart from one another in the length direction of the liquid guide groove 21 and is each in communication with the diffluent groove 31. This facilitates the flowing of the condensed fluid in the liquid guide groove 21 into or out of the diffluent groove 31, and is advantageous in improving the diffluent efficiency of the diffluent groove 31. Of course, the present disclosure is not limited to this, and only one liquid passing opening 22 may be provided.
As illustrated in FIG. 1, the liquid-discharging partition 10 includes a plate body 1, a liquid guide portion 2, and a diffluent portion 3. The liquid guide portion 2 is arranged on a side surface of the plate body 1. The liquid guide groove 21 is defined between the liquid guide portion 2 and the plate body 1. The diffluent portion 3 is arranged on a side surface of the plate body 1. The diffluent groove 31 is defined by the plate body 1 and the diffluent portion 3; and/or the diffluent groove 31 is defined by the plate body 1, the liquid guide portion 2, and the diffluent portion 3.
For example, as illustrated in FIG. 1 and FIG. 2, the liquid guiding portion 2 arranged on a side surface of the plate body 1, and the liquid guide groove 21 is defined by the liquid guiding portion 2 and the plate body 1. The diffluent portion 3 is arranged on a side surface of the plate body 1, and the diffluent groove 31 is defined by the plate body 1, the liquid guide portion 2, and the diffluent portion 3. The diffluent groove 31 is in communication with the liquid guide groove 21 through two liquid passing openings 22.
As illustrated in FIG. 1 and FIG. 2, the liquid-discharging partition 10 further includes a first liquid retaining rib 4 arranged on the plate body 1, located within the diffluent groove 31, and spaced apart from the liquid guide portion 2. It can be understood that the arrangement of the first liquid retaining rib 4 in the diffluent 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.
As illustrated in FIG. 1 and FIG. 2, the liquid-discharging partition 10 further includes a second liquid retaining rib 5 arranged on the plate body 1, located within the diffluent groove 31, and spaced apart from the liquid guide portion 2. The second liquid retaining rib 5 is connected to the first liquid retaining rib 4. An extending direction of the second liquid retaining rib 5 is not parallel to an extending direction of the first liquid retaining rib 4. It can be understood that by a cross arrangement of the first liquid retaining rib 4 and the second liquid 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 of liquid guide ribs 4 is provided and spaced apart from one another. Every two adjacent first liquid retaining ribs 4 are connected to each other by a second liquid retaining rib 5. Here, a plurality refers to two or more. It can be understood that the first liquid retaining ribs 4 and the second liquid retaining ribs 5 are in a cross arrangement, and every two adjacent first liquid retaining ribs 4 are connected by the second liquid 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 and FIG. 2, on a plane parallel to the plate body 1, at least one of an extending direction of the first liquid retaining rib 4 or an extending direction of the second liquid retaining rib 5 is not parallel to the length direction of the liquid guide groove 21. For example, neither the extending direction of the first liquid retaining rib 4 nor the extending direction of the second liquid retaining rib 5 is parallel to the length direction of the liquid guide groove 21. Therefore, when the negative pressure is generated in the air duct, the resistance of the first liquid retaining rib 4 and the second liquid retaining rib 5 to the back flowing of the condensed fluid can be further increased.
Further, as illustrated in FIG. 1, the liquid-discharging partition 10 further includes a third liquid retaining rib 6 arranged on the plate body 1 and located within the diffluent groove 31. The third liquid retaining rib 6 is parallel to the first liquid retaining rib 4. The third liquid retaining rib 6 is located between two adjacent first liquid retaining ribs 4 and spaced apart from the second liquid retaining rib 5. Therefore, the first liquid retaining rib 4, the second liquid retaining rib 5, and the third liquid 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 in FIG. 1, a plurality of third liquid retaining ribs 6 may be provided, and the plurality of third liquid retaining ribs 6 are arranged in parallel and spaced apart from each other.
In some embodiments of the present disclosure, referring to FIG. 2, the liquid guide groove 21 has a first side wall 213 and a second side wall 214 that are opposite to each other. For example, as illustrated in FIG. 2, the first side wall 213 and the second side wall 214 are defined by inner side walls of the liquid guide portion 2 that are opposite to each other in the F2 direction. At least one of the first side wall 213 or the second side wall 214 has a liquid guide rib 7 provided on an inner surface thereof. The liquid guide rib 7 on one of the first side wall 213 and the second side wall 214 extends obliquely towards the other of the first side wall 213 and the second side wall 214. In other words, only one of the first side wall 213 and the second side wall 214 has a liquid guide rib 7 provided on an inner surface thereof, and the liquid guide rib 7 extends obliquely towards the other of the first side wall 213 and the second side wall 214. Alternatively, as illustrated in FIG. 2, each of the first side wall 213 and the second side wall 214 has a liquid guide rib 7 provided on an inner surface thereof, and the liquid guide rib 7 on either one of the first side wall 213 and the second side wall 214 extends obliquely towards the other of the first side wall 213 and the second side wall 214. In this way, the provision of the liquid guide rib 7 is beneficial for increasing the resistance to the flowing of the condensed fluid in the liquid 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, the liquid guide rib 7 extends obliquely towards the outlet 212 of the liquid guide groove 21 from outside to inside in the width direction of the liquid guide groove 21. In the F2 direction, a direction approaching the first side wall 213 and a direction approaching the second side wall 214 is "outside", and a direction approaching a center of the liquid guide groove 21 is "inside". It can be understood that, during the collection of the condensed fluid, the liquid guide rib 7 can play a role in guiding water, and when the negative pressure is generated and the back flowing is caused, the liquid 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 of liquid guide ribs 7 is provided and spaced apart from one another in the length direction of the liquid guide groove 21. Therefore, by the arrangement of the plurality of liquid 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 of liquid guide ribs 7 includes a first liquid guide rib 71 and a second liquid guide rib 72. The first liquid guide rib 71 has an end connected to the first side wall 213, and another end extending obliquely towards the outlet 212 of the liquid guide groove 21 and spaced apart from the second side wall 214. The second liquid guide rib 72 has an end connected to the second side wall 214, and another end extending obliquely towards the outlet 212 of the liquid guide groove 21 and spaced apart from the first side wall 213. It can be understood that, by the arrangement of the first liquid guide rib 71 and the second liquid guide rib 72 that are spaced apart from each other, during the collection of the condensed fluid, the first liquid guide rib 71 and the second liquid 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 first liquid guide rib 71 and the second liquid 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 first liquid guide ribs 71 and a plurality of second liquid guide ribs 72. The plurality of first liquid guide ribs 71 and the plurality of second liquid guide ribs 72 are arranged alternately and spaced apart from each other in the length direction of the liquid 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 the first side wall 213 and the second side wall 214 closer to the diffluent portion 3. Therefore, the structure is simple, and is beneficial to the processing and forming of the liquid-discharging partition 10.
In some embodiments of the present disclosure, the liquid guiding portion 2 and the diffluent portion 3 are each a flexible member. For example, the liquid guide portion 2 and the diffluent portion 3 are each a silicone member or a rubber member. In this way, a sealing performance between the liquid-discharging partition 10 and an inner bottom wall of an air duct housing 20 can be enhanced, which is beneficial to preventing the condensed fluid from flowing into the air duct through gaps between the liquid guide portion 2, the diffluent portion 3, and the air 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 second liquid retaining rib 5, the third liquid retaining rib 6, and the liquid guide rib 7 are each a flexible member. For example, the first liquid retaining rib 4, the second liquid retaining rib 5, the third liquid retaining rib 6, and the liquid guide rib 7 are each a silicone member or a rubber member.
Referring to FIG. 3 and FIG. 4, a dryer 100 according to embodiments of the present disclosure includes an air duct housing 20 and the liquid-discharging partition 10 for the dryer 100 according to the above embodiments of the present disclosure. The air duct housing has a chamber 201 where an evaporator 30 and a condenser 40 are mounted. The liquid-discharging partition 10 is located within the chamber 201. A liquid-discharging channel a is defined between an inner bottom wall of the chamber 201 and each of the liquid guide groove 21 and the diffluent groove 31.
For example, as illustrated in FIG. 3 and FIG. 4, each of the evaporator 30 and the condenser 40 is arranged on the liquid-discharging partition 10 and can play a role in pressing the liquid-discharging partition 10 tight. The chamber 201 has a water guide groove 202 provided on the inner bottom wall thereof. The evaporator 30 is arranged on the water guide groove 202, and the water guide groove 202 is in communication with the inlet 211 of the liquid guide groove 21. When the dryer 100 operates normally, i.e., the negative pressure is not generated in the air duct, the condensed fluid on the evaporator 30 can flow downwards into the water guide groove 202, then flow into the liquid guide groove 21 and the diffluent groove 31 through the inlet 211 of the liquid guide groove 21, and finally be discharged through the outlet 212 of the liquid 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 the outlet 212 of the liquid guide groove 21, and flows into the liquid guide groove 21 and the diffluent groove 31 after passing through the outlet 212 of the liquid guide groove 21. By the provision of the liquid guide groove 21 and the diffluent 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 the liquid guide groove 21.
According to the dryer 100 of the embodiments of the present disclosure, by the provision of the liquid-discharging partition 10 for the dryer 100 according to the above embodiments of the present disclosure, when the negative pressure is generated in the air duct, the condensed fluid flowing back to the outlet 212 of the liquid guide groove 21 can flow to the liquid guide groove 21 and the diffluent groove 31. On one hand, the diffluent effect can be achieved to reduce the 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 and therefore is beneficial to improving the drying efficiency.
