Description

Technical Field

[0001] This utility model relates to a clothes dryer with a loop airflow for drying clothes, and belongs to the technical field of clothes dryers. Background Technology

[0002] Most box-type external circulation dryers currently on the market have a set of PTC heating elements placed at the bottom of the box, blowing hot air upwards, and a circulating fan at the top to evaporate the moisture on the clothes into steam and exhaust it outwards, gradually drying the clothes inside the box. However, the disadvantage of this structure is that the heating fan is at the bottom, and water droplets on the clothes are easy to fall onto the PTC heater, affecting the life of the heater. Utility Model Content

The door assembly is hinged to the housing, and a power board assembly is located inside the housing. The top of the housing has a top air inlet communicating with the inside of the housing. The PTC heater is located at the inner top of the housing, and the inlet fan is also located at the inner top of the housing. The inlet fan draws air from outside the housing through the top air inlet, passes through the PTC heater, and then enters the housing. The circulating fan box is located at the inner bottom of the housing, and the circulating fan is located inside the circulating fan box. The circulating fan box has a circulating air inlet and a circulating air outlet, with the circulating air outlet facing upwards.

[0026] The present invention will now be described in detail with reference to specific embodiments.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a clothes dryer with a circular airflow path includes a housing 1, a PTC heater 9, an inlet fan 91, a circulating fan 4, a circulating fan box 5, and a door assembly 8. The door assembly is hinged to the housing, and a power board assembly 3 is located inside the housing. A top air inlet 10 connects to the inside of the housing. The PTC heater and the inlet fan 91 are located at the top inner part of the housing, allowing outside air to enter through the top air inlet 10, pass through the PTC heater, and then enter the housing. The circulating fan box 5 is located at the bottom inner part of the housing, and the circulating fan 4 is located within it. The circulating fan box has a circulating air inlet 51 and a circulating air outlet 52, with the outlet facing upwards. The angle and direction can be determined according to design requirements. An exhaust vent 61 connects to the outside at the bottom of the housing. As is conventional, a clothes drying rack 2 is located inside the housing. In this example, the partition 6 and the housing form an exhaust channel, and the exhaust vent connects to the outside through this channel. Depending on the design requirements, PCT heaters can also be other conventional heaters.

[0028] A further improvement in this example is that a top ventilation chamber 11 is provided at the top of the enclosure, with a top air inlet 10 communicating with the top ventilation chamber. The top ventilation chamber has a top ventilation outlet 12 communicating with the interior of the enclosure, and the PTC heater is located inside the top ventilation chamber. Placing it inside the ventilation chamber is safer.

[0029] A further improvement in this example is that the air intake fan is located in the top ventilation chamber.

[0030] A further improvement in this example is that the air intake fan 91 is fixed on the PTC heater 9 to form a PTC fan heating assembly, or a conventional PTC fan heating assembly can be used.

[0031] A further improvement in this example is that the PTC heater is located at the corresponding position of the air outlet of the top ventilation chamber.

[0032] Working principle: During drying, the inlet fan, PTC heater, and bottom circulating fan 4 work simultaneously. The inlet fan 91 draws air from outside the chamber into the top air inlet 10, passes through the PTC heater, and then enters the chamber. As the hot air descends, it is drawn in by the circulating fan 4 and from the circulating air inlet 51 into the circulating fan housing 5, then blown upwards from the circulating air outlet 52 back towards the top of the chamber. Figure 7As shown, a U-shaped high-temperature airflow is formed inside the cabinet, which accelerates the flow of hot air inside the cabinet, helps to remove moisture from the clothes inside the cabinet more quickly, and allows the internal temperature of the cabinet to reach uniformity more quickly. This solution's high-temperature airflow is specifically designed for the hard-to-dry areas of the cabinet-type dryer, thereby achieving a rapid drying effect, while also protecting the PTC heater to the greatest extent, avoiding the heater being affected by water droplets, and preventing any impact on the heater's working performance and service life.

[0033] Example 2: As Figure 2 As shown, this example is characterized by the power board assembly 3 being located in the top ventilation chamber. The structure is compact. The rest is the same as in Example 1.

[0034] Example 3: As Figure 7 As shown, the characteristic of this example is that the circulating air inlet 51, circulating air outlet 52, and exhaust outlet 61 are arranged in the rear, middle, and front positions in sequence, or the circulating air inlet, circulating air outlet, and exhaust outlet are arranged in the front, middle, and rear positions in sequence. This structure facilitates the meandering flow of hot air within the chamber, ensuring full utilization of the hot air and resulting in high drying efficiency. The rest is the same as in Example 1 or Example 2.

[0035] Example 4: The characteristic of this example is that...

[0036] The circulating air inlet, circulating air outlet, and exhaust outlet are arranged in the order of left, center, and right, or in the order of right, center, and left. This structure facilitates the circulation of hot air within the chamber. The rest is the same as in Embodiment 1 or Embodiment 2.

[0037] Example 5: Figure 6 As shown, this example features a control panel assembly 7 on the door assembly 8. This facilitates control panel settings on the door. The rest is the same as in the embodiments described above.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
