Description

Technical Field

[0001] This application relates to the field of dryer technology, and in particular to a dryer drainage structure and a dryer. Background Technology

[0002] Condenser dryers dry clothes quickly by increasing temperature, reducing humidity, and increasing airflow speed to expand the evaporation area. They use circulating hot air to condense the water vapor from the clothes back into water in a condenser, which is then discharged from the machine.

[0046] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0047] This embodiment provides a clothes dryer, which includes a clothes dryer drainage structure, such as... Figures 1-3 As shown, the drainage structure of the dryer includes: a base plate 1 and a water pump 2.

[0048] The base plate 1 includes a main body 11 and a recessed area 12. The bottom of the recessed area 12 is at a lower level than the bottom of the main body 11. The recessed area 12 is located below the evaporator 200 of the dryer. The length direction of the recessed area 12 is along a first direction.

[0049] The water pump 2 has its pump inlet located at one end of the recessed area 12 along the first direction and connected to the recessed area 12, so as to pump water from the recessed area 12.

[0050] The dryer drainage structure and dryer provided in this embodiment include a base plate 1 comprising a main body 11 and a recessed area 12. The recessed area 12 is located below the condensate drain outlet 31, forming a water storage tank. The length direction of the recessed area 12 is along a first direction, thus confining the condensate discharged from the evaporator 200 within a relatively narrow and long water storage space. The water pump 2's intake port is located at one end of the recessed area 12 along the first direction. It is understandable that during actual water pumping, a certain height of water residue is unavoidable on the base plate 1. The recessed area 12 in this embodiment narrows the water storage space, effectively accumulating water, thus making it easier to pump away most of the water in the recessed area 12, reducing the amount of water residue in the water storage space after pumping. Therefore, the dryer drainage structure and dryer provided in this embodiment improve the problem of bacteria growth and odor generation in dryers to a certain extent.

[0051] In an alternative embodiment, such as Figure 3As shown, in the drain structure of the dryer in this embodiment, the bottom surface of the recessed area 12 gradually decreases in height from the ground along a first direction, from the position away from the water inlet of the water pump 2 to the position of the water inlet of the water pump 2. In this embodiment, by setting a slope on the bottom surface of the recessed area 12, the water flows to a lower position, that is, it gathers at the water inlet of the water pump 2, which can further reduce the amount of water remaining in the water storage space after pumping. Optionally, the bottom surface of the recessed area 12 gradually decreases in height from the ground along a second direction, from the position away from the water inlet of the water pump 2 to the position of the water inlet of the water pump 2, and the second direction is perpendicular to the first direction. This setting can further promote the water flow to gather at the water inlet of the water pump 2.

[0052] In an alternative embodiment, such as Figures 1-2 As shown, along the vertical direction, the projection of the evaporator 200 is located within the recessed area 12, while the projection of the condenser 300 of the dryer is located outside the recessed area 12. In this embodiment, the area of ​​the recessed area 12 does not pass under the condenser 300. Therefore, the area of ​​the base plate 1 used for condensate flow is significantly reduced compared to the base plate 1 of existing dryers, which is beneficial for the centralized collection of condensate and reduces condensate residue.

[0053] In an alternative embodiment, such as Figures 1-3 As shown, the dryer's drainage structure also includes a water-proof cover plate 3, which covers the top of the recessed area 12 and has a condensate drain outlet 31. In this embodiment, the water-proof cover plate 3 covers the top of the recessed area 12, providing a certain degree of sealing to the water storage space of the recessed area 12, preventing external impurities from entering the water storage space, and avoiding the accumulation of dust or particulate matter in the recessed area 12 after long-term use. At the same time, the water-proof cover plate 3 can also be flush with the main body 11, improving the overall flatness of the base plate 1 and the water-proof cover plate 3, and facilitating the installation and arrangement of the evaporator 200 and the condenser 300.

[0054] In an alternative embodiment, such as Figure 3 As shown, the water pump 2 is located at one end of the recessed area 12 along the first direction. In this embodiment, placing the water pump 2 at one end of the recessed area 12 facilitates the placement of its water inlet close to the recessed area 12, thus shortening the length of the pipeline and reducing space requirements.

[0055] In an alternative embodiment, such as Figure 1 , Figure 4As shown, the dryer drainage structure of this embodiment also includes: a drain pipe 4, an overflow pipe 5, a water storage tank, and a water level sensor 6; one end of the drain pipe 4 is connected to the water pump 2, and the other end is connected to the water storage tank, so that the water pumped by the water pump 2 is discharged into the water storage tank for storage; one end of the overflow pipe 5 is connected to the top of the water storage tank, and the other end is connected to the water pump 2, so that the water overflowing from the top of the water storage tank flows back to the water pump 2; the water level sensor 6 is installed on the water pump 2 to sense the water flowing back to the water pump 2 from the overflow pipe 5. In this embodiment, the water level sensor 6 is used to monitor the water storage status of the water storage tank to prevent the water storage capacity of the water storage tank from exceeding the limit. Its working principle is: when the water storage tank is full, the overflowing water flows back to the water pump 2 from the top overflow pipe 5. The flowing water returns to the water pump 2 and triggers the water level sensor 6. The water level sensor 6 can be connected to the switch or alarm device of the water pump 2 to shut down the water pump 2 or issue an alarm.

[0056] In an optional embodiment, the dryer drainage structure further includes an alarm device electrically connected to the water level sensor 6, which is used to trigger an alarm when a signal is received from the water level sensor 6, so that the user can promptly dispose of the water stored in the water tank.

[0057] In an alternative embodiment, such as Figure 5 As shown, the dryer in this embodiment includes a housing 100 and an evaporator 200. Along a first direction, the length L1 of the housing 100 is greater than the sum of the length L3 of the evaporator 200 and the length L2 of the water pump 2, i.e., L1 > L2 + L3. The water pump 2 and the evaporator 200 are installed side-by-side within the housing 100 along the first direction. In this embodiment, the difference between the size of the evaporator 200 and the length of the housing 100 is designed to accommodate the water pump 2, making full use of the space within the housing 100.

[0058] In an alternative embodiment, such as Figure 5 As shown, the dryer also includes a condenser 300 and a compressor 400. The condenser 300 is disposed on one side of the evaporator 200 along a second direction, which is perpendicular to the first direction. The compressor 400 and the condenser 300 are installed side by side in the housing 100 along the first direction. In this embodiment, the first set of equipment, the compressor 400 and the condenser 300, are designed to be installed side by side, and the second set of equipment, the water pump 2 and the evaporator 200, are designed to be installed side by side. The two sets of equipment are approximately the same size, which allows for better allocation of installation space.

[0059] In an alternative embodiment, such as Figure 5As shown, along the first direction, the length L4 of the compressor 400 is greater than the length L2 of the water pump 2, and the length L5 of the condenser 300 is less than the length L3 of the evaporator 200. In this embodiment, the compressor 400 is larger than the water pump 2. By selecting the relatively larger compressor 400 and the condenser 300 to be installed side by side, and the relatively smaller water pump 2 and the evaporator 200 to be installed side by side, the space of the outer casing 100 is utilized more fully, which is beneficial to reducing the overall size of the dryer.

[0060] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
