Description

Technical Field

[0001] This utility model relates to the field of clothes dryers, and in particular to a clothes dryer. Background Technology

[0002] A clothes dryer is a household appliance used to dry clothes, typically in humid weather or when there is not enough space to hang clothes to dry.

[0003] There are two main types of clothes dryers: Exhaust dryers: These dryers work by heating air and then expelling the moisture outdoors through an exhaust pipe. They are usually cheaper but less efficient and may damage clothes. Condenser dryers: These dryers use condensation technology to recycle moisture and do not require an exhaust pipe. They are generally more energy-efficient and gentler on clothes, but are relatively more expensive. Therefore, condenser dryers consist of an evaporator, a condenser, and a compressor.

[0004] During the operation of a condenser dryer, the evaporator absorbs heat and produces condensate on its surface. Under normal circumstances, the condensate flows along the water path under the evaporator into the condensate collection tank. However, since the evaporator and condenser are distributed sequentially along the air path, under high air volume conditions, a small portion of the air will enter the lower side of the evaporator, blowing the condensate to the condenser side. This causes fluctuations in the condensation temperature of the condenser, preventing it from reaching the target temperature, thus prolonging the drying time and affecting the drying performance. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a clothes dryer with the advantage of facilitating the discharge of condensate into a condensate collection tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clothes dryer includes a base, an evaporator, and a condenser; the evaporator and the condenser are disposed on the base; the evaporator and the condenser are distributed sequentially along the airflow direction; a water channel and a condensate collection tank are provided on the base; the water channel is located below the evaporator and one end is connected to the condensate collection tank; the clothes dryer also includes an air guide seat; the evaporator and the condenser are mounted on the base via the air guide seat; the air guide seat blocks airflow from entering the water channel from below the evaporator along the airflow direction, and has an airflow channel located below the evaporator inside; the airflow channel is parallel to the water channel direction and has an opening at its upper end; the airflow space at the end of the airflow channel near the condensate collection tank is larger than the airflow space at the end away from the condensate collection tank.

[0008] By adopting the above technical solution, the air enters the evaporator along the airflow direction. Most of the air passes through the evaporator, and a small portion enters the airflow channel. Since the airflow space at the end of the airflow channel near the condensate collection tank is larger than that at the end away from the condensate collection tank, the dynamic pressure at the end of the airflow channel near the condensate collection tank is smaller than that at the end away from the condensate collection tank. This helps the condensate to enter the condensate collection tank along the water path, preventing the condensate from flowing towards the condenser side.

[0009] Optionally, a partition parallel to the airflow channel is provided inside the airflow channel; an airflow notch is formed at the end of the partition near the condensate collection tank; the airflow channel forms a first airflow outlet as an airflow space at the end near the condensate collection tank through the airflow notch.

[0010] By adopting the above technical solution, a first air guide is formed at the end of the air guide channel near the condensate collection tank. In this way, the air guide space at the end of the air guide channel near the condensate collection tank is larger than the air guide space at the end away from the condensate collection tank. As a result, the dynamic pressure at the end of the air guide channel near the condensate collection tank is smaller than the dynamic pressure at the end away from the condensate collection tank, which helps the condensate to enter the condensate collection tank along the water path and prevents the condensate from flowing to the condenser side.

[0011] Optionally, a baffle is provided at the end of the air guide channel away from the condensate collection tank; a gap is provided between the bottom of the baffle and the bottom surface of the water channel; the air guide channel is located on the side of the baffle away from the condensate collection tank to form a second air guide opening as an air guide space; the volume of the second air guide opening is smaller than the volume of the first air guide opening.

[0012] By adopting the above technical solution, the presence of the baffle increases the resistance to wind. At the same time, the volume of the second air guide is smaller than that of the first air guide. The dynamic pressure at the end of the air guide channel near the condensate collection tank is smaller than that at the end away from the condensate collection tank. This helps the condensate to enter the condensate collection tank along the water path, and prevents the condensate from flowing to the condenser side.

[0013] Optionally, the end of the partition away from the condensate collection tank extends to the baffle.

[0014] By adopting the above technical solution, there is no gap between the end of the baffle and the partition away from the condensate collection tank, which further increases the resistance to wind and makes it easier for the wind to flow to the side of the condensate collection tank, thereby helping the condensate to enter the condensate collection tank along the water path.

[0015] Optionally, the air guide seat also has a reinforcing rib perpendicular to the air guide channel; both ends of the reinforcing rib are connected to the wall constituting the air guide channel and the partition plate respectively; a gap is provided between the bottom of the reinforcing rib and the bottom surface of the water channel.

[0016] By adopting the above technical solution, the presence of reinforcing ribs enhances the strength of the entire air guide seat, thereby enabling it to withstand greater mass and providing more stable support for the evaporator and condenser.

[0017] Optionally, the wall of the air guide channel near the upstream side of the airflow direction is a first baffle; the first baffle is located on the upstream side of the evaporator near the airflow direction.

[0018] By adopting the above technical solution, the air blown towards the lower side of the evaporator will be blocked by the first baffle and will not be able to travel directly in its original direction. This will prevent the condensate from being blown towards the condenser, so it will not affect the normal operation of the condenser.

[0019] Optionally, the first baffle has an inclined surface that is inclined from bottom to top along the airflow direction.

[0020] By adopting the above technical solution, the inclined surface of the first baffle will guide the hot and humid air blown towards the lower side of the evaporator to the evaporator, so that the evaporator can recover more heat.

[0021] Optionally, the upper end of the first baffle is provided with a blocking element to reduce the gap between the first baffle and the evaporator; the blocking element is a baffle rib or a sponge strip.

[0022] By adopting the above technical solution, the presence of the blocking component reduces the gap between the first baffle and the evaporator. The smaller the gap, the better, which reduces the possibility of wind entering the lower side of the evaporator through the gap between the first baffle and the evaporator, and reduces the possibility of affecting the flow direction of condensate. The sponge strip is more effective as a blocking component than the baffle rib, but the production cost will also increase.

[0023] Optionally, the air guide seat is integrally formed on the base or is disposed separately.

[0024] By adopting the above technical solutions, when the air guide seat is integrally formed on the base, the number of parts is reduced and the assembly steps are reduced, thereby improving the assembly efficiency; when the air guide seat is set separately, the problem of condensate flowing to the condenser can be solved without changing the shape of the base, making implementation more convenient.

[0025] Optionally, the water channel is a sunken water guide trough; the bottom surface of the water guide trough is inclined and the end near the condensate collection trough is lower than the end away from the condensate collection trough.

[0026] By adopting the above technical solution, the bottom surface of the water guide channel, which slopes downward toward the condensate collection tank, facilitates the condensate to flow into the condensate collection tank due to its own weight. At the same time, the space at the end of the air guide channel near the condensate collection tank is larger than the space at the end away from the condensate collection tank. The air entering the air guide channel will flow toward the condensate collection tank, making it easier for the condensate to enter the condensate collection tank along the water path.

[0039] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0040] Example 1: A clothes dryer is disclosed, with reference to Figure 1 and Figure 2The system includes a base 10, an air guide seat 20, an evaporator 30, and a condenser 40. The air guide seat 20 is mounted on the base 10. The evaporator 30 and condenser 40 are mounted on the air guide seat 20 and distributed sequentially along the airflow direction 50. The base 10 is provided with a water passage 100 and a condensate collection tank 101. One end of the water passage 100 is connected to the condensate collection tank 101. The air guide seat 20 has an airflow channel 202 with an open top. The airflow channel 202 is located within the evaporator 30. Directly below; the top of the air guide channel 202 is located on both sides of the evaporator 30 and has water inlet holes 204 formed therein; the two ends of the air guide channel 202 along the water path direction 60 are respectively connected to the water inlet holes 204; the air guide seat 20 guides most of the air to pass through the evaporator 30 and the condenser 40 in one go, and a small part of the air passes through the evaporator 30 and then enters the air guide channel 202 and the water path 100 downwards, with a part of it facing the condensate collection tank 101 and the other part away from the condensate collection tank 101.

[0041] refer to Figure 1 and Figure 2 Two pairs of connecting posts 26 are provided on the upper surface of the air guide seat 20; connecting plates 27 are fixed to the end of the evaporator 30 and the end of the condenser 40 away from the condensate collection tank 101 and the end of the condensate collection tank 101 respectively; vertical connecting slots are formed on the connecting posts 26 for the end of the connecting plate 27 to be vertically inserted; the two ends of the connecting plate 27 parallel to the air duct direction 50 are inserted from top to bottom into the vertical connecting slots of the corresponding connecting posts 26.

[0042] refer to Figure 3 The water channel 100 is a sunken water guide channel; the bottom surface of the water guide channel is inclined and the end near the condensate collection tank 101 is lower than the end away from the condensate collection tank 101.

[0043] refer to Figures 3-5 The bottom of the air guide seat 20 is provided with a bottom cavity 203; the part of the bottom cavity 203 directly above the water channel 100 is the air guide channel 202; the air guide channel 202 is located at one end of the bottom cavity 203 near the upstream side of the air channel direction 50; the upper opening of the air guide channel 202 is located directly above the water channel 100; the part of the bottom cavity 203 near the side wall of the condensate collection tank 101 and directly opposite the air guide channel 202 has a notch.

[0044] refer to Figures 3-5A pair of parallel baffles 22 are formed inside the air guide channel 202; the bottom of the baffles 22 abuts against the bottom surface of the water passage 100; in order to make the air guide space at the end of the air guide channel 202 near the condensate collection tank 101 larger than the air guide space at the end away from the condensate collection tank 101, an air guide notch 220 is formed at the end of the baffles 22 near the condensate collection tank 101. In this way, a first air guide 200 is formed at the end near the condensate collection tank 101 through the air guide notch 220 as an air guide space. Thus, the air guide space at the end of the air guide channel 202 near the condensate collection tank 101 is larger than the air guide space at the end away from the condensate collection tank 101. Thus, the dynamic pressure at the end of the air guide channel 202 near the condensate collection tank 101 is less than the dynamic pressure at the end away from the condensate collection tank 101, which is conducive to the flow of condensate into the condensate collection tank 101. In fact, while ensuring the strength of supporting the evaporator 30 and condenser 40, the baffle 22 can have the air guide gap 220 as large as possible.

[0045] To increase the overall strength of the air guide seat 20, reinforcing ribs 23 are provided between a pair of partitions 22 and between the partitions 22 and the side wall of the bottom cavity 203 near the upstream side of the air passage; a gap is provided between the bottom of the reinforcing ribs 23 and the bottom surface of the water passage 100.

[0046] Working principle of Example 1: Most of the air passes through the evaporator 30 and the condenser 40 in sequence. A small portion of the air passes through the evaporator 30 and then flows downward through the upper opening of the air guide channel 202 into the air guide channel 202 and the water channel 100. Since the dynamic pressure at the end of the air guide channel 202 near the condensate collection tank 101 is less than the dynamic pressure at the end away from the condensate collection tank 101, the condensate will flow into the condensate collection tank 101 along the water channel direction 60 after entering the water channel 100, and will not be blown towards the condenser 40 to cause accumulation, thus avoiding affecting the operation of the condenser 40.

[0047] Example 2: The difference between Example 2 and Example 1 is as follows: (Refer to...) Figures 3-5 To further increase the airflow space difference between the end of the airflow channel 202 near the condensate collection tank 101 and the end away from the condensate collection tank 101, a baffle 24 is provided at the end of the airflow channel 202 away from the condensate collection tank 101; a gap is provided between the bottom of the baffle 24 and the bottom surface of the water channel 100; a second air outlet 201 is formed on the side of the airflow channel 202 away from the baffle 24 as an airflow space; the volume of the second air outlet 201 is smaller than the volume of the first air outlet 200; to further increase the resistance to wind, the end of the baffle 22 away from the condensate collection tank 101 extends to the baffle 24, so that there is no gap between the baffle 24 and the baffle 22, and the wind is not easy to pass through.

[0048] Of course, in addition to the two methods mentioned above, the air guide channel 202 can also be made into a trapezoidal shape so that the space at the end of the air guide channel 202 near the condensate collection tank 101 is larger than the space at the end away from the condensate collection tank 101. In this way, the air guide channel 202 is more likely to allow the wind to flow towards the end of the air guide channel 202 near the condensate collection tank 101, which is conducive to the flow of condensate into the condensate collection tank 101.

[0049] Example 3: The difference between Example 3 and Example 1 is as follows: (Refer to...) Figure 4 and Figure 5 The wall of the bottom cavity 203 near the upstream side of the airflow 50, i.e., the wall of the airflow duct 202 near the upstream side of the airflow 50, is the first baffle 21. The first baffle 21 is located on the upstream side of the evaporator 30 near the airflow 50. The upper end of the first baffle 21 is connected to a baffle rib. The smaller the distance between the baffle rib and the supporting evaporator 30, the better. Considering assembly, the gap between the vertical side wall and the supporting evaporator 30 is less than 1mm, thus reducing the possibility of air entering the lower side of the evaporator 30 through the gap between the supporting evaporator 30 and the first baffle 21. In order to make the above-mentioned wind-blocking effect better, a sponge strip is attached to the upper end of the first baffle 21. The sponge strip is located between the upper end of the first baffle 21 and the supporting evaporator 30. At this time, the sponge strip replaces the baffle rib. Due to the elasticity of the sponge strip itself, the wind-blocking effect is better than that of the baffle rib, but the production cost is higher.

[0050] To guide more air into the evaporator 30, refer to... Figure 4 and Figure 5 The first baffle 21 has an inclined surface that is inclined from bottom to top along the airflow direction 50.

[0051] In the above embodiments, the air guide seat 20 is an integrally formed component, so there is no need to change the structure of the base 10 in order to solve technical problems; in other embodiments, the air guide seat 20 can also be integrally formed with the base 10, so that no additional parts are added during assembly.

[0052] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
