DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application.

[0055] In the prior art, people dry clothes mainly through a heat pump system, which heats the clothes in a care cabinet to remove moisture from the clothes.

[0056] The heat pump system includes compressor, evaporator, condenser, copper pipe, cooling fan and other parts. The fan circulates air between the cabinet and the heat pump system. The hot air from the heat pump system flows through the wet clothes to carry moisture. Then, the heat pump system cools down the clothes to separate the moisture. Then, the clothes are heated and the temperature is raised. This cycle repeats to dry the clothes.

[0057] Although the above solution can achieve dehumidification care for clothes, the heat pump system has many parts, resulting in a complex overall structure. In addition, by exhausting the heated air into the entire cabinet, the hot air not only exchanges heat with the clothes, but also with the cabinet, which inevitably loses a lot of heat energy and causes energy waste.

[0058] The present invention provides a rotary dehumidifier and a clothing care cabinet, such as Figure 1 and Figure 2 As shown, Figure 1 This is a structural schematic diagram of a clothing care cabinet proposed by the present invention. Figure 2 The front view of a clothing care cabinet proposed by the present invention includes a cabinet body 100, a rotary dehumidifier 300 disposed at the bottom of the cabinet body 100, a storage bin 200 disposed above the rotary dehumidifier 300, and a hanger for placing wet clothes in the storage bin 200.

[0059] like Figure 3 As shown, Figure 3The structure diagram of a rotary dehumidifier proposed by the present invention is shown in FIG. The rotary dehumidifier 300 includes a main circulation mechanism 400, a secondary circulation mechanism 500 and a rotary mechanism 600. The main circulation mechanism 400 is used to communicate with the inside of the cabinet 100 to form a main circulation airflow; the secondary circulation mechanism 500 is used to communicate with the outside of the cabinet 100 to form a secondary circulation airflow.

[0060] The main circulation mechanism 400 includes a main circulation air duct 410, the secondary circulation mechanism 500 includes a secondary circulation air duct 510 and a heater 520, the heater 520 is located in the secondary circulation air duct 510, and the wheel mechanism 600 includes a dehumidification wheel 610;

[0061] A portion of the dehumidification wheel 610 is located on the main circulation air duct 410 , and another portion of the dehumidification wheel 610 is located on the secondary circulation air duct 510 , and rotates between the main circulation air duct 410 and the secondary circulation air duct 510 .

[0062] The main circulation air duct 410 is used to provide cold air to the clothing care cabinet. The wet air after treating the clothes enters the main circulation air duct 410 after the moisture is absorbed by the dehumidification wheel 610, forming a main circulation airflow.

[0063] After the dehumidification wheel 610 absorbs moisture in the main circulation air, it rotates the absorbed moisture portion into the secondary circulation air duct 510 through self-rotation.

[0064] The secondary circulation air duct 510 absorbs external cold air, and the heater 520 is used to heat the dehumidification wheel 610 to heat the moisture generated by the dehumidification wheel 610. The cold air becomes hot air after passing through the heater 520, and the hot air then passes through the dehumidification wheel 610 to take away the moisture to form humid hot air, and finally is discharged through the secondary circulation air duct 510 to form a secondary circulation airflow.

[0065] The moisture on the clothes in the cabinet 100 is removed by the uninterrupted main circulation airflow and the secondary circulation airflow, thereby achieving the purpose of dehumidification care. The structure of the present invention is simple, and the heater 520 only needs to heat the dehumidification wheel 610 to achieve the purpose of discharging moisture, without increasing the temperature of the entire cabinet 100, thereby avoiding the waste of heat energy of the heater 520.

[0066] In the above optional technical solutions, if Figure 4 As shown, Figure 4 The schematic diagram of the structure of the rotary mechanism of the rotary dehumidification device proposed by the present invention is shown in FIG. The rotary mechanism 600 further includes a driving member 620 and a gear 621 connected to the driving member 620. The dehumidification rotary wheel 610 has a plurality of ventilation holes. The outer wall of the dehumidification rotary wheel 610 is evenly spaced with a plurality of teeth 622. The gear 621 meshes with the teeth 622. The driving member 620 drives the dehumidification rotary wheel 610 to rotate through the gear 621 and the teeth 622.

[0067] Exemplarily, the driving member 620 is a driving motor.

[0068] The ventilation holes on the dehumidification wheel 610 are used for air to pass through, and the hole walls of the ventilation holes are made of water-absorbent materials, such as lithium chloride, lithium chloride and zeolite molecular sieve. When the humid air in the main circulation air duct 410 passes through the ventilation holes, the water-absorbent materials on the hole walls absorb the moisture in the humid air, which is then heated by the heater 520 in the secondary circulation air duct 510 and diffused into the secondary circulation air duct 510 and carried away by the secondary circulation airflow.

[0069] In the above optional technical solutions, if Figure 5 As shown, Figure 5 The schematic diagram of the structure of the secondary circulation mechanism of the rotary dehumidification device proposed by the present invention. The secondary circulation air duct 510 includes a secondary air inlet duct section 511, a secondary transition duct section 512 and a secondary air outlet duct section 513. The first ends of the secondary transition duct section 512 and the secondary air outlet duct section 513 are both connected to the secondary air inlet duct section 511. The heater 520 is located at the second end of the secondary transition duct section 512, and the heater 520 is located below the dehumidification rotary wheel 610. The second end of the secondary air outlet duct section 513 is located above the second end of the secondary transition duct section 512, and another part of the dehumidification rotary wheel 610 is located inside the second end of the secondary air outlet duct section 513.

[0070] Among them, the auxiliary air outlet duct section 513 and the auxiliary transition duct section 512 are both arranged at the top of the auxiliary air inlet section. In this embodiment, the flow direction of the auxiliary circulating airflow is that the external cold air enters from the first end of the auxiliary air inlet duct section 511, flows upward from the second end of the auxiliary air inlet duct section 511 to the first end of the horizontally arranged auxiliary transition duct section 512, and then flows upward from the second end of the auxiliary transition duct section 512 to pass through the partial dehumidification wheel 610, and then enters the second end of the auxiliary air outlet duct section 513 upward, and flows from the first end of the auxiliary air outlet duct section 513 into the condenser 700 in the auxiliary air inlet duct section 511, and finally is discharged through the air outlet arranged in the auxiliary air inlet duct section 511.

[0071] like Figure 6 and Figure 7 As shown, Figure 6 A schematic diagram of the condenser structure of a rotary dehumidification device proposed by the present invention; Figure 7 The condenser of the rotary dehumidification device proposed by the present invention is located in the auxiliary air inlet duct section. In the above optional technical solution, the auxiliary circulation mechanism 500 also includes a condenser 700, and the auxiliary air inlet duct section 511 has an auxiliary air inlet 540 and an auxiliary air outlet 550.

[0072] The condenser 700 is arranged in the auxiliary air inlet duct section 511. The condenser 700 has a separated air inlet channel 730 and an air outlet channel 740. The air outlet channel 740 is connected to the first end of the auxiliary air outlet duct section 513 and the auxiliary air outlet 550, so that the humid hot air formed by the moisture generated by the heating and dehumidification wheel 610 is discharged in sequence through the first end of the auxiliary air outlet duct section 513, the air outlet channel 740 and the auxiliary air outlet 550.

[0073] The air inlet channel 730 is connected to the auxiliary air inlet duct section 511 , and the external cold air enters the auxiliary transition duct section 512 through the auxiliary air inlet 540 and the air inlet channel 730 in sequence.

[0074] From the above, it can be seen that the hot and humid air in the auxiliary air outlet duct section 513 enters the air outlet channel 740, and the external cold air enters the air inlet channel 730. The function of the condenser 700 is to exchange heat between the hot and humid air in the air outlet channel 740 and the cold air in the air inlet channel 730, so that the moisture in the hot and humid air is condensed and precipitated, and the moisture is not discharged into the external environment and affects the external environment.

[0075] like Figure 8 As shown, Figure 8 This is a bottom view of the secondary circulation mechanism of a rotary dehumidifier proposed by the present invention. The secondary air outlet 550 is arranged at the bottom of the secondary air inlet duct section 511, and the air outlet channel 740 of the condenser 700 is connected to the secondary air outlet 550. In order to better collect the condensed water precipitated from the air outlet channel 740, a water tank can be arranged at the bottom of the secondary air outlet 550.

[0076] In the above optional technical solution, the condenser 700 includes a plurality of partitions 720 and at least one connecting plate 710, each partition 720 is inserted on the connecting plate 710, and the two ends of each partition 720 are respectively opposite to the first end of the auxiliary air outlet duct section 513 and the air outlet.

[0077] A through slot is provided in the partition plate 720 to form an air inlet channel 730 , and an air outlet channel 740 is formed between two adjacent partition plates 720 .

[0078] In this embodiment, if Figure 6 As shown, three connecting plates 710 are placed in parallel, and an installation space is formed between two adjacent connecting plates 710, wherein each installation space includes five mutually parallel partitions 720, the partitions 720 are perpendicular to the connecting plates 710, and both ends of each partition 720 are respectively plugged into the connecting plates 710 on both sides, and a through groove is provided in the partition 720. The two partitions 720 in the two installation spaces are correspondingly connected, and the two through grooves on the two correspondingly connected partitions 720 are connected to extend the length of the through groove, and five extended through grooves are formed in the two installation spaces. The inner cavities of the five extended through grooves together constitute an air inlet channel 730, and the air inlet channel 730 is connected to the auxiliary air inlet duct section 511.

[0079] In the above technical solution, in the same installation space, a cavity is formed between two adjacent partitions 720, and a total of 8 cavities are formed in the two installation spaces. The 8 cavities together constitute an air outlet channel 740, wherein the two ends of the air outlet channel 740 are respectively connected to the first end of the auxiliary air outlet duct section 513 and the auxiliary air outlet 550.

[0080] Among them, the cold air entering the air inlet channel 730 from the auxiliary air inlet duct section 511 and the humid hot air entering the air outlet channel 740 from the auxiliary air outlet duct section 513 exchange heat through the side wall of the partition 720. The moisture in the humid hot air in the air outlet channel 740 is condensed when it encounters cold and precipitated from the side wall of the partition 720 in the air outlet channel 740.

[0081] Exemplarily, the cross-sectional shape of the through slot is a rectangle.

[0082] like Fig. 9 and Fig.10 As shown, Fig. 9 This is a schematic structural diagram of a rotary dehumidification device proposed by the present invention, in which an auxiliary fan is located in an auxiliary transition air duct; Fig.10 This is a schematic diagram of the structure of a rotary dehumidification device proposed by the present invention, in which the heater is located in the secondary transition air duct. In the above optional technical solution, the secondary circulation mechanism 500 also includes a secondary fan 530, which is located in the first end of the secondary transition air duct section 512, and the heater 520 is located in the second end of the secondary transition air duct section 512. The secondary fan 530 is used to drive the secondary circulation airflow.

[0083] like Fig.11 , Fig.12 and Fig.13 As shown, Fig.11 A schematic diagram of the structure of the main circulation air duct of a rotary dehumidification device proposed by the present invention; Fig.12 A schematic diagram of the structure of a main fan of a rotary dehumidification device proposed by the present invention; Fig.13 The schematic diagram of the structure of the installation slot of a rotary dehumidification device proposed by the present invention is as follows. In the above optional technical solution, the main circulation mechanism 400 further includes a main fan 420, and the main fan 420 is located in the main circulation air duct 410. The main fan 420 is used to drive the main circulation airflow.

[0084] The main circulation air duct 410 includes a main air inlet duct section 411 and a main air outlet duct section 412. The main air inlet duct section 411 has a main air inlet 440. The main air inlet duct section 411 has a mounting groove 450. The dehumidification wheel 610 is arranged in the mounting groove 450. A part of the mounting groove 450 is communicated with the second end of the secondary transition duct section 512, and another part of the mounting groove 450 is communicated with the main air inlet 440. The mounting groove 450 and the main air outlet are both used to communicate with the clothing care cabinet.

[0085] In this embodiment, the main air inlet duct section 411 is a square shell, and the main air outlet duct section 412 is located on the side wall of the main air inlet duct section 411. The main air inlet 440 is located at the top of the main air inlet duct section 411, and the outer edge of the main air outlet extends upward and outward to form a mounting groove 450. A fixing bracket and a rotating shaft are arranged in the mounting groove 450 or in the main air inlet 440 to support the dehumidification wheel 610 and rotate the dehumidification wheel 610.

[0086] It should be noted that if Fig.14 As shown, Fig.14 This is a cross-sectional view of a dehumidification wheel of a rotary dehumidification device proposed by the present invention. The cross-section of the main air outlet is three-quarters of a circle, and the radius of the main air outlet is the same as the radius of the dehumidification wheel 610. When the dehumidification wheel 610 is installed in the installation groove 450, three-quarters of the dehumidification wheel 610 is just located at the top of the main air outlet. The remaining quarter is located at the top of the second end of the secondary transition air duct and at the same time at the bottom of the second end of the secondary air outlet air duct. The heater 520 is located at the bottom of the dehumidification wheel 610.

[0087] Exemplarily, the driving member 620 is installed on the top of the main air inlet duct section 411 .

[0088] like Fig.15 and Fig.16 As shown, Fig.15 A schematic structural diagram of a wind shielding member of a rotary dehumidification device proposed by the present invention; Fig.16 The schematic diagram of the installation of the air outlet grille and the air inlet grille of a rotary dehumidifier device proposed by the present invention. In the above optional technical solution, it also includes an air shield 430, an air outlet grille 312 and an air inlet grille 311, the air shield 430 is located above the dehumidifier wheel 610 and is covered on the mounting groove 450, the air shield 430 closes the second end of the secondary transition air duct section 512, the air shield 430 is connected to the mounting groove 450, the air inlet grille 311 is covered on the air shield 430, and the air outlet grille 312 is covered on the main air outlet.

[0089] Among them, the wind-blocking member 430 is an annular baffle, and an air-blocking plate 431 is arranged inside the annular baffle. The annular baffle and the two air-blocking plates 431 form a channel with a cross-section of three quarters of a circle. This channel is connected to the main air outlet, and is used to prevent the main circulation airflow from flowing to other places when entering the dehumidification wheel 610, and to ensure that the main circulation airflow only passes through three quarters of the dehumidification wheel 610, and the remaining channel with a cross-section of one quarter of a circle is used for the passage of the secondary circulation airflow. Thereby, it is ensured that three quarters of the dehumidification wheel 610 are used to absorb the moisture of the humid air in the main circulation airflow, and one quarter of the dehumidification wheel 610 is located in the secondary circulation air duct 510, and the moisture on this one quarter is evaporated and taken away. Since the dehumidification wheel 610 absorbs moisture at a slow speed, the dehumidification part and the evaporation part of the dehumidification wheel 610 are set at a ratio of 3:1, and this ratio can also be adjusted according to actual conditions.

[0090] The air baffle 431 is used to block the main circulation airflow from entering the auxiliary air outlet duct section 513.
