[0034] Based on the problem pointed out in the background art, the existing clothing care machine has the problem of inconsistent drying progress on the inside and outside of the clothes during the drying process. The utility model provides an air duct system and a clothing care machine of a clothing care machine, by arranging a lower air duct, a middle air duct and an upper air duct connected in sequence in the clothing care machine, and a clothes hanger connected to the upper air duct inside, and respectively arranging clothes hanger air outlets connecting the clothes hanger air duct and the care chamber at both ends of the clothes hanger, and arranging an air outlet connected to the care chamber on the lower air duct, and sending high-temperature air into the care chamber through the air outlet through a heating device and a fan installed in the lower air duct, and sending the high-temperature air into the care chamber through the two clothes hanger air outlets and into the inside and sleeves of the clothes, thereby achieving simultaneous drying of the inside and outside of the clothes, making the heating of the inside and outside of the clothes more uniform, and improving the overall drying efficiency.
[0035] Specifically, if Figure 1As shown, the utility model provides an air duct system of a clothing care machine, wherein the clothing care machine includes a care chamber 1, and the air duct system includes: a downwind duct 2, which is arranged below the care chamber 1, and is provided with a first air outlet 21, a second air outlet 22 and a return air outlet 23, and the first air outlet 21 and the return air outlet 23 are both connected to the care chamber 1; a fan 6, which is installed in the downwind duct 2 and can inhale air from the return air outlet 23 and blow it out from the first air outlet 21 and the second air outlet 22; a heating device, which is installed in the downwind duct 2 and can heat the air in the downwind duct 2; an upwind duct 4, which is installed in the upwind duct The upper part of the nursing chamber 1, and the upper air duct 4 is provided with an upper air inlet 41 and an upper air outlet 42; the clothes hanger, the clothes hanger includes a connecting part 51 and a supporting part 52, the connecting part 51 is connected to the upper air duct 4, and the two ends of the supporting part 52 can respectively extend into the two sleeves of the clothes, and the hanger is provided with a hanger air duct inside the clothes hanger, and the hanger air duct is provided with an air inlet, a third air outlet 521 and a fourth air outlet 522, the air inlet is connected with the upper air outlet 42, the third air outlet 521 and the fourth air outlet 522 are respectively located at the two ends of the supporting part 52 and are connected with the nursing chamber 1; the middle air duct 3, the two ends of the middle air duct 3 are respectively connected with the second air outlet 22 and the upper air inlet 41.
[0036] Exemplarily, the clothing care machine includes a cabinet, and a care chamber 1 is formed inside the cabinet. The care chamber 1 is separated from the downwind duct 2 by a partition, and the first air outlet 21, the second air outlet 22 and the return air outlet 23 are all arranged on the partition. The intermediate air duct 3 is arranged on one side of the care chamber 1 in the vertical direction, or is arranged in the side wall of the care chamber 1. The lower end of the intermediate air duct 3 is connected with the downwind duct 2 through the second air outlet 22, and the upper end of the intermediate air duct 3 is connected with the upper air duct 4 through the upper air inlet 41. Preferably, a clothes hanging component (such as a clothes hanging rod, etc.) is installed on the upper part of the care chamber 1 of the utility model, which can hang hangers, and the interior of the clothes hanging rod is set as a cavity structure, thereby forming an upper air duct 4.
[0037] The interior of the clothes hanger is also configured as a cavity structure, thereby forming a clothes hanger air duct, the connecting part 51 is configured as a hook structure, which can be hung on the clothes hanging rod, and the supporting part 52 is configured as a support arm extending horizontally to both sides, which can support the shoulders of the clothes to stretch the clothes. At the same time, the two ends of the supporting part 52 can extend to the two sleeves of the clothes. The air inlet can be set on the connecting part 51, or on the supporting part 52, as long as it can be connected with the upper air outlet 42. For example, the two can be connected by a hose. The third air outlet 521 and the fourth air outlet 522 are respectively arranged at the two ends of the supporting part 52, so that the airflow can be directly introduced into the cuffs of the clothes.
[0038] The heating device and the fan 6 are preferably installed in the downwind duct 2 so as to send the high-temperature air into the care chamber 1 through the first air outlet 21, so that the high-temperature air can dry the outer surface of the clothes; at the same time, the high-temperature air can also be sent through the second air outlet 22, the middle air duct 3, the upper air duct 4, and the hanger air duct and then through the third air outlet 521 and the fourth air outlet 522 into the interior of the clothes and the two cuffs respectively, so that the high-temperature air can dry the inner surface of the clothes.
[0039] This allows the inside and outside of the clothes to be heated more evenly, preventing the inside of the clothes from being under-dried and the outside from being over-dried, and improving the overall drying effect.
[0040] Preferably, if Figure 1 As shown, the air duct system of the present invention further includes a regulating valve 8 , which is connected to the air outlet of the fan 6 , the first air outlet 21 and the second air outlet 22 , and can adjust the opening of the first air outlet 21 and / or the second air outlet 22 .
[0041] Exemplarily, the regulating valve 8 is configured as an electrically controlled three-way valve, whose inlet is connected to the air outlet of the fan 6, and its two outlets are respectively connected to the first air outlet 21 and the second air outlet 22. Regulating valves are installed at both outlets, which can independently control the opening of the first air outlet 21 and the second air outlet 22, and thus control the flow rate of high-temperature air flowing to the inside and outside of the clothes, so as to adjust the drying intensity of the inside and outside of the clothes as needed.
[0042] Specifically, when the humidity inside the clothes is higher than the humidity outside the clothes, the opening of the second air outlet 22 can be increased to increase the air supply to the inside of the clothes, thereby achieving accurate heat distribution and keeping the drying progress inside and outside the clothes as synchronized as possible, thereby preventing the situation in traditional clothes drying equipment where the inside of the clothes is not dried enough and the outside is dried too much, thereby improving the drying effect and reducing energy consumption.
[0043] Preferably, if Figure 1 As shown, the heating device of the present invention is configured as a heat pump system, which includes a compressor, a condenser 71 and an evaporator 72 .
[0044] Exemplarily, the heat pump system is configured as a heat exchange circulation system consisting of a compressor (not shown in the figure), a condenser 71, an evaporator 72, and a throttling device, which has the characteristics of energy saving, environmental protection, and high thermal efficiency; at the same time, it can also achieve a combination of hot and cold, that is, the air is heated and dehumidified by the heating and cooling of the condenser 71 and the evaporator 72 respectively.
[0045] Preferably, if Figure 1 As shown, the air duct system of the present invention further includes an auxiliary heating device 73 .
[0046] Exemplarily, the auxiliary heating device 73 is usually set as an electric heating device with a faster heating speed, such as a heating wire, PTC, etc. In this solution, the auxiliary heating device 73 can be installed at any position of the air duct system, such as the lower air duct 2, the middle air duct 3 or the upper air duct 4, etc. Through the joint action of the auxiliary heating device 73 and the heating device, the heating efficiency of the air can be effectively improved, thereby improving the drying effect of the clothes.
[0047] Preferably, if Figure 1 As shown, the auxiliary heating device 73 of the present invention is installed in the upper air duct 4.
[0048] Since the air is heated in the lower air duct 2, it needs to pass through the middle air duct 3, the upper air duct 4 and the hanger air duct before it can be sent into the interior of the clothes. During this process, the high-temperature air will dissipate heat outward through the pipe wall of the air duct, thereby causing heat loss, so that the temperature of the air sent into the clothes drops, affecting the drying efficiency inside the clothes.
[0049] In this solution, the auxiliary heating device 73 is installed in the upper air duct 4, which can compensate for the heat loss during the flow of air from the lower air duct 2 to the upper air duct 4, so that the air flow entering the hanger air duct can still maintain a high temperature, ensuring the drying efficiency of the inside of the clothes.
[0050] Preferably, if Figure 1 As shown, the auxiliary heating device 73 of the present invention is configured as a PTC component.
[0051] Through such an arrangement, the auxiliary heating device 73 has an automatic constant temperature function, which helps to save energy while maintaining a constant temperature.
[0052] Preferably, if Figure 1 As shown, the air duct system of the present invention further includes a humidity sensor 9 .
[0053] The humidity sensor 9 can detect the air humidity in the care chamber 1 in real time, and then judge the drying progress of the clothes, so as to adjust the drying intensity by adjusting the temperature of the heating device and the opening of each air outlet to achieve the purpose of precise drying.
[0054] Preferably, if Figure 1 As shown, the humidity sensor 9 of the present invention is installed at the return air outlet 23 and / or on the clothes hanger.
[0055] The humidity sensor 9 at the return air outlet 23 mainly detects the air humidity flowing through the outer surface of the clothes, and the humidity sensor 9 on the clothes hanger can detect the air humidity inside the clothes. By transmitting the humidity signal to the controller, the controller can adjust the opening of the first air outlet 21 and the second air outlet 22 according to the humidity changes at different positions, and then adjust the drying intensity of the outside and inside of the clothes, so that the drying progress inside and outside the clothes can be kept synchronized as much as possible, thereby achieving reasonable distribution of heat, improving the utilization rate of thermal energy, and helping to save energy consumption.
[0056] Preferably, the upper air duct 4 of the present invention is also provided with a top air outlet (not shown in the figure) connected to the nursing chamber 1, and / or the middle air duct 3 is also provided with a middle air outlet (not shown in the figure) connected to the nursing chamber 1.
[0057] For example, the high-temperature airflow enters the care chamber 1 through the top air outlet and can dry the clothes from above. It can also dry the middle part of the clothes from the side of the clothes through the middle air duct 3, so as to achieve all-round and multi-angle drying of the clothes, which is beneficial to increase the heating area of the clothes, make the clothes more evenly heated, and improve the drying efficiency.
[0058] In addition, the clothing care machine further provided by the present invention on the basis of the above-mentioned air duct system adopts the above-mentioned air duct system, and thus has the technical effects of the above-mentioned air duct system. Compared with the clothing care machine before the improvement, the clothing care machine of the present invention can dry both the inside and outside of the clothes at the same time, making the clothes more evenly heated and improving the drying effect.
[0059] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
