Description

Technical Field

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

[0002] A dryer is a device that accelerates the drying of items (especially clothes) through heating and ventilation. It utilizes a hot air circulation system to heat the internal air and blow it onto the items to be dried, causing the moisture to evaporate and be discharged through an exhaust vent or condenser, thus shortening the time required for natural air drying. Commonly used in homes in conjunction with washing machines, it solves the problem of drying clothes on rainy days, during the rainy season, or when space is limited; it is also widely used in textiles, agriculture, and food processing. Household dryers are mainly divided into three categories: exhaust type (requires an external drain pipe), condenser type (with an internal water tank to collect moisture), and heat pump type (higher energy efficiency, low-temperature protection for clothes).

[0003] The inventors have discovered at least the following problems in the prior art: Existing heat pump dryers rely on internal airflow self-circulation. A fan generates a self-circulating airflow that is heated by an electric heater before entering the drying drum to dry the clothes, removing moisture and creating a humid, hot airflow. This humid, hot airflow passes through a filter to remove impurities and then flows into the evaporator to remove moisture and collect condensate. The air cooled by the evaporator then flows into the condenser for reheating, creating a continuous cycle. However, this process relies on refrigerant circulating between the evaporator and condenser for cooling. As the airflow passes through the evaporator, it carries heat, resulting in heat loss due to the humid, hot airflow, making it impossible to recover residual heat.

[0004] Therefore, this solution provides a dryer to solve the above problems. Utility Model Content

[0020] In a further embodiment, a drive motor 19 is installed on the back of the support 11. The output end of the drive motor 19 is connected to the back of the drying drum 13. The outer periphery of the drying drum 13 is a humid heat chamber 16, and the outer periphery of the inner partition cylinder 12 is a guide cavity 17.

The input end of the induced draft fan 14 is connected to the guide cavity 17, and the output end of the induced draft fan 14 is connected to a drying heat flow pipe 15. The drying heat flow pipe 15 is aligned with the inside of the drying drum 13.

[0021] In this embodiment, the drive motor 19 is used to drive the drying drum 13 to rotate, thereby allowing the clothes inside to come into full contact with heat and thus dry; a connecting hole 6 is provided at the housing 111 where the drive motor 19 is installed, and a hinged one-way cover 7 is installed on the inner side of the connecting hole 6.

[0025] In this embodiment, the hot and humid airflow filtered by the filter screen 18 passes above the side guide plate 122 and inside the back guide plate 124 before entering the recycling bin 31.

[0026] In a further embodiment, a connection port 32 is provided on one side of the recycling bin 31, the connection port 32 is aligned with the connecting port 125, and a water collection tank 34 is inserted into the bottom of the recycling bin 31.

[0027] In this embodiment, the connection port 32 and the connector port 125 are aligned so that hot and humid gas can enter and flow upward through the evaporation pipe 41 and the waste heat recovery pipe 51.

[0028] In a further embodiment, each row of heat dissipation fins 42 has an evaporation tube 43 running through its interior, and each row of evaporation tubes 43 is connected to each other by a connecting tube 44. The two ends of the evaporation tubes 43 are respectively connected to the input end of the compressor 35 and the output end of the condenser 21.

[0029] In this embodiment, the refrigerant in the refrigerant tank 36 is located in the evaporator tube 43 inside the condenser 21. When the hot and humid airflow passes through, the refrigerant absorbs some heat and is processed by the compressor 35 into a high-temperature gaseous refrigerant. It is then introduced into the condenser 21 to heat the airflow passing through the condenser 21. After the refrigerant in the condenser 21 is discharged, it passes through the expansion valve and other components to become a low-temperature liquid refrigerant and enters the evaporator tube 43 for continuous circulation.

[0030] In a further embodiment, an external airflow inlet 54 is provided on one side of the waste heat recovery pipe 51, which is connected to the input end of the external air intake fan 56. An external airflow outlet 55 is provided on the back of the waste heat recovery pipe 51, which is connected to the guide cavity 17. One side of the heat exchange core 53 is connected to the external airflow outlet 55, and the other side is connected to the recovery port 57, which is connected to the input end of the fan 33.

[0031] In this embodiment, heat exchange core 1 52 and heat exchange core 2 53 are existing heat exchange cores, which allow heat conduction when the heat flow and the external airflow cross flow, so that the external airflow is heated and directly introduced into the guide cavity 17, while the cooled airflow will enter the condenser 21 for secondary heating before entering the guide cavity 17.

[0032] The working principle of this utility model is as follows: When the dryer is operating, the induced draft fan 14, heater 112, drive motor 19, compressor 35, refrigerant tank 36, external air intake fan 56, and condenser 21 will all operate. The induced draft fan 14 will draw airflow heated by the heater 112 from the guide cavity 17 and then fill the drying drum 13 to dry the clothes inside. The hot and humid gas discharged from the drying drum 13 into the humid heat chamber 16 will pass through the notch 121 and filter screen 18, and then pass through the top of the heater 112, the inside of the back guide plate 124, and the connection port 125 to reach the inside of the recovery box mechanism 3. After entering the recovery box 31, the hot and humid gas will move upward and pass through the evaporation mechanism 4 and the recovery mechanism 5 in sequence. Then, it will be guided into the condenser 21 by the fan 33 for reheating and then sent back to the guide cavity 17, thus continuously circulating itself. When the hot and humid airflow passes through the interior of the evaporation pipe 41, the refrigerant is inside the evaporation pipe 43, which makes the temperature of the outer periphery of the evaporation pipe 43 and the heat dissipation fins 42 lower than that of the hot and humid airflow. As a result, the hot and humid airflow will condense into water and fall into the water collection tank 34. The airflow, dried and cooled by the evaporation mechanism 4, will sequentially pass through the lower left corner of heat exchange core 1 52 and exit from the upper right corner, then through the lower right corner of heat exchange core 2 53 and exit from the upper left corner to reach the recovery port 57, and then be guided into the condenser 21 through the inlet of the fan 33. During this process, the operation of the external fan 56 will introduce the external airflow, allowing the external airflow to enter from the external airflow inlet 54 and exchange heat perpendicularly with the heat flow passing through heat exchange core 1 52 and heat exchange core 2 53, thereby further cooling the airflow discharged from the evaporation mechanism 4. The heat in the airflow will be transferred to the new airflow and reintroduced into the guide cavity 17 from the external airflow outlet 55. Thus, the airflow processed by the evaporator can undergo heat exchange and waste heat recovery again, thereby further reducing the energy consumption of the dryer.

[0033] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
