[0008] In the preferred technical solution of the above air duct device, the heating pipe assembly includes a circulation pipe, a fresh air pipe, a fan, and a heating member. The heat recovery pipe assembly is in close contact with at least a part of the circulation pipe. The two ends of the circulation pipe are respectively communicated with the air inlet of the nursing chamber and the air outlet of the nursing chamber.

The air outlet of the fresh air pipe is located inside the circulation pipe. The fan is installed in the circulation pipe, and the heating member is installed in the fresh air pipe.
[0009] In the preferred technical solution of the above air duct device, the heat recovery pipe assembly includes a heat absorption pipe and a connecting pipe. The air inlet of the heat absorption pipe is communicated with the external space. The air outlet of the heat absorption pipe is communicated with the air inlet of the connecting pipe. The air outlet of the connecting pipe is communicated with the air inlet of the fresh air pipe. The heat absorption pipe is sleeved on the circulation pipe, and the circulation pipe divides the heat absorption pipe into an upper heat absorption pipe and a lower heat absorption pipe.
[0010] In the preferred technical solution of the above air duct device, the direction of the air outlet of the fresh air pipe is the same as the air flow direction in the circulation pipe.
[0011] In the preferred technical solution of the above air duct device, the direction of the air inlet of the fresh air pipe is vertically downward.
[0012] In the preferred technical solution of the above air duct device, the heating member is installed at the air inlet of the fresh air pipe.
[0013] In the preferred technical solution of the above air duct device, the heating member is set as a PTC heater.
[0014] In the preferred technical solution of the above air duct device, the fresh air pipe further includes a damper.

[0015] In the preferred technical solution of the above air duct device, the air duct device further includes a filter, and the filter is installed at the air inlet of the heat absorption pipe assembly, and / or the air duct device further includes a condenser, and the condenser is installed at the air outlet of the nursing chamber.
[0016] In a second aspect, the present invention provides a clothing care device, and the clothing care device includes the above air duct device.
[0017] In the case of adopting the above technical solution, the clothing care device of the present invention includes a care chamber. The air duct device includes a heating duct assembly and a heat recovery duct assembly. The two ends of the heating duct assembly are respectively communicated with the air inlet of the care chamber and the air outlet of the care chamber. The heating duct assembly can form a high-temperature circulating air flow between the heating duct assembly and the care chamber. The air inlet of the heat recovery duct assembly is communicated with the external space, the air outlet of the heat recovery duct assembly is communicated with the heating duct assembly, and the heat recovery duct assembly is at least partially in close contact with the heating duct assembly and can introduce external air into the heating duct assembly to recover the heat dissipated by the heating duct assembly. Through such a setting, on the one hand, the negative pressure formed by the high-temperature circulating air flow at the air outlet of the heat recovery duct assembly can suck external air into the heating duct assembly; on the other hand, the close contact between the heat recovery duct assembly and the heating duct assembly enables the air flow in the heat recovery duct to absorb the heat dissipated by the heating duct assembly and recover the heat lost by the heating duct assembly through the reflux of air, thereby effectively reducing heat loss and improving the drying efficiency; on the other hand, it can prevent the heat dissipated from accumulating in the device, causing the device to heat up and even cause failures.
[0018] Further, the heating duct assembly of the present invention includes a circulation duct, a fresh air duct, a fan and a heating member. The heat recovery duct assembly is at least partially in close contact with the circulation duct. The two ends of the circulation duct are respectively communicated with the air inlet of the care chamber and the air outlet of the care chamber. The air inlet of the fresh air duct is located outside the circulation duct and is communicated with the air outlet of the heat recovery duct assembly. The air outlet of the fresh air duct is located inside the circulation duct. The fan is installed in the circulation duct, and the heating member is installed in the fresh air duct. Through such a setting, first, the fan and the circulation duct can form a circulating air flow between the circulation duct and the care chamber; second, compared with the traditional air duct device that installs the heating member in the circulation duct, this case adds a fresh air duct and installs the heating member in the fresh air duct. On the one hand, it can prevent the heating member from obstructing the circulating air flow and ensure the flow rate and velocity of the circulating air flow; on the other hand, it can first heat the air flow in the fresh air duct and then suck the air flow in the fresh air duct into the circulation duct to heat the circulating air flow, which can prevent the circulating air flow from bringing foreign matters such as lint on the clothes into the circulation duct and then adhering to the heating member, causing the device to overheat or even cause a fire accident, improving the drying efficiency and use safety of the air duct device; on the other hand, the external air entering from the fresh air duct has a lower humidity, which is more conducive to improving the drying efficiency of the clothes.
[0019] Furthermore, the heat recovery pipe assembly of the present invention includes a heat absorbing pipe and a connecting pipe, the air inlet of the heat absorbing pipe is connected to the external space, the air outlet of the heat absorbing pipe is connected to the air inlet of the connecting pipe, the air outlet of the connecting pipe is connected to the air inlet of the fresh air pipe, the heat absorbing pipe is sleeved on the circulation pipe, and the circulation pipe separates the heat absorbing pipe into an upper heat absorbing pipe and a lower heat absorbing pipe. Through such a setting, the heat absorbing pipe is wrapped on the circulation pipe, so that the upper heat absorbing pipe and the lower heat absorbing pipe sandwich the circulation pipe in the middle, which can more effectively absorb the heat emitted from various parts of the circulation pipe, improve the heat recovery efficiency, minimize the loss of heat, and improve the drying effect.
[0020] Furthermore, the direction of the air outlet of the fresh air duct of the present invention is consistent with the direction of the airflow in the circulation duct. Through such an arrangement, the influence of the airflow in the fresh air duct and the airflow in the circulation duct on the flow velocity of the airflow in the circulation duct at the intersection can be reduced, so that the fusion of the two airflows is smoother, and the flow velocity and flow rate of the circulation airflow are guaranteed to be stable.
[0021] Furthermore, the air inlet of the fresh air duct of the present invention is directed vertically downward. With such a configuration, on the one hand, the air inlet facing downward is not easy to accumulate dust; on the other hand, the internal space of the clothing care device can be better utilized, making the layout of each component more reasonable.
[0022] Furthermore, the heating component of the present invention is installed at the air inlet of the fresh air duct. With such an arrangement, the installation height of the heating component is relatively low, which is more conducive to the heated high-temperature gas flowing upward, so that when the fan is not started, the high-temperature gas can automatically flow toward the circulation duct, further playing a role in preventing heat loss.
[0023] Furthermore, the heating component of the present invention is configured as a PTC heater. Through such a configuration, the power and temperature of the heating component are controllable, reducing the risk of fire caused by excessive temperature, while the heating efficiency is higher, and the drying efficiency of the equipment is improved while also improving the safety during use.
[0024] Furthermore, the fresh air duct of the present invention further includes a damper, which is located below the heating component and hinged at the air inlet of the fresh air duct. The damper can rotate around the hinge point to open or close the air inlet of the fresh air duct, and / or the damper is set as a mesh structure. Through such a setting, on the one hand, the opening of the damper can be automatically adjusted according to the negative pressure generated by the circulating airflow during operation to ensure smooth air intake, and the setting of the filter can prevent the inhalation of foreign matter; on the other hand, it can block the internal washing foam to prevent the overflow of the washing foam and avoid pollution to the indoor air.
[0025] Furthermore, the air duct device of the present invention further includes a filter, which is installed at the air inlet of the heat absorption pipe assembly, and / or the air duct device further includes a condenser, which is installed at the air outlet of the nursing chamber. Through such an arrangement, on the one hand, it can filter the inhaled air to prevent the entry of external foreign objects, further improving the cleanliness of the inhaled air; on the other hand, it can condense the circulating air flowing out of the nursing chamber, reduce the humidity in the circulating air, and play a role in drying the circulating air.
[0026] In addition, the clothing care device further provided by the present invention on the basis of the above technical solution includes the above air duct device, and thus has the technical effects possessed by the above air duct device. Compared with the clothing care device before improvement, the clothing care device of the present invention has higher drying efficiency and use safety.

[0033] The following describes the preferred embodiments of the present invention with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0034] It should be noted that in the description of the present invention, the terms "inner", "outer", "upper", "lower", "top", "bottom" and other terms indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention.
[0035] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "arrangement", "connection", "installation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] Based on the technical problems pointed out in the background art, in the existing clothing care equipment, the circulating air flow brings foreign matters such as lint on the clothes into the air duct device, so that a large amount of foreign matters adhere to the heating component, resulting in poor air flow circulation and too high temperature of the heating component. At the same time, the air duct device also dissipates heat to the outside, resulting in too fast heat loss, thus affecting the drying efficiency and use safety of the equipment. The present invention provides an air duct device and a washing equipment of a washing equipment, aiming to divide the air duct device into a heating pipe component and a heat recovery pipe component. The two ends of the heating pipe component are respectively communicated with the air inlet and the air outlet of the care chamber, and a high-temperature circulating air flow can be formed between the heating pipe component and the care chamber. The air inlet and the air outlet of the heat recovery pipe component are respectively communicated with the external space and the heating pipe component, and are at least partially in close contact with the heating pipe component. The high-temperature circulating air flow can suck the external air into the heating pipe component through the heat recovery pipe component to recover the heat dissipated by the heating pipe component, improving the drying efficiency of the clothing care equipment and reducing the risk of fire caused by overheating of the equipment, and improving the safety during use.
[0037] Specifically, as Figure 1 shown, the clothing care equipment of the present invention includes a care chamber 1. The air duct device includes a heating pipe component and a heat recovery pipe component. The two ends of the heating pipe component are respectively communicated with the air inlet and the air outlet of the care chamber 1. The heating pipe component can heat the air and form a high-temperature circulating air flow between the heating pipe component and the care chamber 1. The air inlet of the heat recovery pipe component is communicated with the external space, the air outlet of the heat recovery pipe component is communicated with the heating pipe component, and the heat recovery pipe component is at least partially in close contact with the heating pipe component to absorb the heat dissipated by the heating pipe component. A negative pressure is formed at the air outlet of the heat recovery pipe component of the high-temperature circulating air flow, and the external air can be sucked into the heating pipe component through the heat recovery pipe component to recover the heat dissipated by the heating pipe component.
[0038] In this case, the care chamber 1 is used to hold clothes and can wash, dehydrate and dry the clothes. The air duct device of the present invention can form a high-temperature circulating air flow to dry the clothes in the care chamber 1. Exemplarily, the heating pipe assembly and the heat recovery pipe assembly are both arranged outside the care chamber 1. The two ends of the heating pipe assembly are hermetically connected to the air inlet and the air outlet of the care chamber 1 respectively, and thus form a sealed circulating air duct with the care chamber 1. In the drying mode of the care device, the circulating air flow is heated into a high-temperature circulating air flow in the heating pipe assembly, and then the high-temperature circulating air flow enters the care chamber 1 to bake the washed clothes at a high temperature, achieving the purpose of drying.
[0039] It should be noted that during the process of the high-temperature circulating air flow flowing in the heating pipe assembly, heat will be transferred out through the pipe wall of the heating pipe assembly, resulting in rapid heat loss and affecting the drying effect. The air duct device in the present invention further includes a heat recovery pipe assembly. The middle part of the heating pipe assembly also has a side opening. The air inlet of the heat recovery pipe assembly is communicated with the external space, and the air outlet of the heat recovery pipe assembly is hermetically connected to the side opening of the heating pipe assembly. Therefore, when the high-temperature circulating air flow flows at a high speed in the heating pipe assembly, a negative pressure can be formed at the air outlet of the heat recovery pipe assembly to suck the air in the heat recovery pipe, thereby forming a heat recovery air flow in the heat recovery pipe. By making the heat recovery pipe assembly in close contact with the heating pipe assembly, the heat recovery air flow can absorb the heat dissipated by the heating pipe assembly and heat up during the process of flowing around the heating pipe assembly, and then merge into the circulating air flow in the heating pipe assembly, further increasing the temperature of the circulating air flow and achieving the purpose of heat recovery.
[0040] In summary, the negative pressure formed at the air outlet of the heat absorption pipe 31 by the high-temperature circulating air flow can suck the external air into the heating pipe assembly; the close contact between the heat recovery pipe assembly and the heating pipe assembly enables the air flow in the heat recovery pipe to absorb the heat dissipated by the heating pipe assembly, and the heat lost by the heating pipe assembly is recovered through the reflux of the air, effectively reducing the heat loss and improving the drying efficiency; the outward dissipation of heat is blocked, and the accumulation of heat in the device can be avoided, preventing the device from overheating.
[0041] Preferably, as Figures 1 to 4As shown in the figure, the heating pipeline assembly of the present invention includes a circulation pipeline 21, a fresh air pipeline 22, a fan 23 and a heating member 24. The heat recovery pipeline assembly is at least partially in close contact with the circulation pipeline 21. The two ends of the circulation pipeline 21 are respectively communicated with the air inlet and the air outlet of the nursing chamber 1. The air inlet of the fresh air pipeline 22 is located outside the circulation pipeline 21 and is communicated with the air outlet of the heat recovery pipeline assembly. The air outlet of the fresh air pipeline 22 is located inside the circulation pipeline 21. The fan 23 is installed in the circulation pipeline 21, and the heating member 24 is installed in the fresh air pipeline 22.
[0042] Exemplarily, the fan 23 of the present invention is installed at the connection between the air outlet of the nursing chamber 1 and the circulation pipeline 21, and can suck the air in the nursing chamber 1 into the circulation pipeline 21, thereby forming a circulating air flow between the nursing chamber 1 and the circulation pipeline 21. At the same time, a fresh air pipeline 22 is added, and the fresh air pipeline 22 is located between the circulation pipeline 21 and the heat recovery pipeline assembly to seal and communicate the two, so that the heat recovery air flow flows through the heat recovery pipeline assembly and the fresh air pipeline 22 in sequence and then enters the circulation pipeline 21.
[0043] The heating member 24 of the present invention is installed in the fresh air pipeline 22, so that the heating member 24 can first heat the heat recovery air flow flowing into the fresh air pipeline 22, and then make the high-temperature heat recovery air flow merge into the circulating air flow and heat the circulating air flow. Compared with the traditional air duct device in which the heating member 24 is directly installed in the circulation pipeline 21 and the heating member 24 directly heats the circulating air flow, installing the heating member 24 in the fresh air pipeline 22 of the present invention can prevent the heating member 24 from obstructing the circulating air flow and ensure the flow rate and velocity of the circulating air flow; and can prevent the circulating air flow from bringing foreign matters such as lint shed from clothes into the circulation pipeline 21 and adhering to the heating member 24, causing high temperature or even fire accidents of the equipment, improving the drying efficiency and use safety of the air duct device; finally, the humidity of the fresh air inhaled from the external space is much lower than the humidity of the hot and humid air circulated in the nursing chamber 1. Coupled with the two-layer heating effects of heat recovery and the heating member 24, the humidity of the air is further reduced, which further helps to improve the drying efficiency of clothes.
[0044] It should be noted that in practical applications, those skilled in the art can flexibly set the type of the heating member 24. For example, it can be set as an electric heating tube, a resistance wire or a PTC heater, etc., as long as it can realize the heating of the air flow. Such flexible adjustment and change do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.
[0045] Such as Figures 1 to 4As shown, the heat recovery pipeline assembly of the present invention includes a heat absorption pipeline 31 and a connection pipeline 32. The air inlet of the heat absorption pipeline 31 is communicated with the external space, the air outlet of the heat absorption pipeline 31 is communicated with the air inlet of the connection pipeline 32, the air outlet of the connection pipeline 32 is communicated with the air inlet of the fresh air pipeline 22. The heat absorption pipeline 31 is sleeved on the circulation pipeline 21, and the circulation pipeline 21 divides the heat absorption pipeline 31 into an upper layer heat absorption pipeline 311 and a lower layer heat absorption pipeline 312.
[0046] Exemplarily, the inner diameter of the heat absorption pipeline 31 is larger than the outer diameter of the circulation pipeline 21, so that the heat absorption pipeline 31 can be sleeved on the circulation pipeline 21, thereby wrapping the circulation pipeline 21 inside. It should be noted that after assembly, the air inlet and air outlet of the heat absorption pipeline 31 are respectively located on opposite sides of the circulation pipeline 21, so that the air flow direction of the heat absorption pipeline 31 is perpendicular to the air flow direction of the circulation pipeline 21. The upper layer heat absorption pipeline 311 and the lower layer heat absorption pipeline 312 sandwich the circulation pipeline 21 in the middle, enabling the air flow to flow through the upper and lower outer walls of the circulation pipeline 21 from the upper layer heat absorption pipeline 311 and the lower layer heat absorption pipeline 312 respectively, forming a heat absorption layer, avoiding the direct contact of the circulation pipeline 21 with the outside air, so that the heat dissipated by the circulation pipeline 21 is directly taken away by the air flow in the upper layer heat absorption pipeline 311 and the lower layer heat absorption pipeline 312, improving the heat recovery efficiency of the heat absorption pipeline 31, minimizing heat loss to the greatest extent, and enhancing the drying effect.
[0047] It should be noted that the heights of the upper layer heat absorption pipeline 311 and the lower layer heat absorption pipeline 312 can be flexibly set according to the needs of the heating component 24. When the temperature of the heating component 24 is relatively high, the heights of the upper layer heat absorption pipeline 311 and the lower layer heat absorption pipeline 312 can be appropriately increased to improve their heat insulation performance.
[0048] The connection pipeline 32 is set in a bent pipe shape for communicating the air outlet of the heat absorption pipeline 31 with the air inlet of the fresh air pipeline 22, and can introduce the heat recovery air flow into the fresh air pipeline 22.
[0049] Preferably, as Figure 2 shown, the direction of the air outlet of the fresh air pipeline 22 of the present invention is consistent with the air flow direction in the circulation pipeline 21.
[0050] Exemplarily, the air outlet of the fresh air pipeline 22 extends into the circulation pipeline 21, and the part of the fresh air pipeline 22 in the circulation pipeline 21 is set as a bent pipe structure and extends a certain distance along the direction of the circulating air flow, so that the direction of the air outlet of the fresh air pipeline 22 is consistent with the direction of the circulating air flow. This can reduce the air resistance at the intersection of the air flow in the fresh air pipeline 22 and the air flow in the circulation pipeline 21, reduce the influence on the flow rate of the circulating air flow, make the fusion of the two air flows smoother, and ensure the stability of the flow rate and flow volume of the circulating air flow.
[0051] Preferably, as Figure 1 and Figure 3 shown, the air inlet of the fresh air duct 22 of the present invention is vertically downward.
[0052] Exemplarily, the part of the fresh air duct 22 located outside the circulation duct 21 is also set in a bent pipe shape, and its extending direction from the circulation duct 21 to the outside changes from horizontal to vertically downward, so that the air inlet of the fresh air duct 22 is vertically downward. Such a setting can reduce the accumulation of dust and prevent dust from being inhaled during operation; at the same time, the fresh air duct 22 is located between the nursing chamber 1 and the body, which can make better use of the internal space of the clothing care device and make the layout of each component more reasonable.
[0053] Preferably, as Figure 1 、 Figure 3 and Figure 4 shown, the heating member 24 of the present invention is installed at the air inlet of the fresh air duct 22.
[0054] Since the flow direction of the air flow entering the fresh air duct 22 from the air inlet is from bottom to top, in this case, the heating member 24 is installed at the air inlet of the fresh air duct 22, so that the installation height of the heating member 24 is relatively low, which is more conducive to the upward flow of the heated high-temperature gas, so as to ensure that the high-temperature gas automatically flows into the circulation duct 21 even when the fan 23 is not started, further improving the heating efficiency and preventing heat loss.
[0055] Preferably, as Figure 1 、 Figure 3 and Figure 4 shown, the heating member 24 of the present invention is set as a PTC heater.
[0056] The power and temperature of the PTC heater are both controllable, which can reduce the risk of fire caused by excessive temperature. At the same time, the PTC heater has a higher heat generation efficiency, which improves the drying efficiency of the equipment and also improves the safety during use.
[0057] Preferably, as Figure 3 shown, the fresh air duct 22 of the present invention further includes a damper 221. The damper 221 is located below the heating member 24 and is hinged at the air inlet of the fresh air duct 22. The damper 221 can rotate around the hinge point to open or close the air inlet of the fresh air duct 22, and / or the damper 221 is set as a mesh structure.
[0058] Exemplarily, in a preferred embodiment, the hinged end of the air damper 221 is hinged to the pipe wall of the fresh air duct 22. The free end of the air damper 221 can freely rotate around the hinge point. A limiting structure 222 is further provided on the hanging wall on one side of the free end. The limiting structure 222 can limit the downward rotation of the free end, enabling it to only rotate upward. When the free end abuts against the limiting structure 222, the air damper 221 is in a horizontal state. At this time, the air damper 221 closes the air inlet of the fresh air duct 22. When the negative pressure in the circulation duct 21 increases, the air damper 221 rotates upward under the action of the suction force, thereby opening the air inlet of the fresh air duct 22.
[0059] In another preferred embodiment, a plurality of mesh holes are evenly distributed on the air damper 221, making the air damper 221 present a mesh structure. When the negative pressure in the circulation duct 21 is relatively small, the mesh holes on the air damper 221 can meet the air flow requirements. At this time, the air damper 221 remains in a horizontal state, and the mesh holes play a role in filtering foreign objects from the outside.
[0060] When the negative pressure in the circulation duct 21 is relatively large, the upward suction force on the air damper 221 increases accordingly, causing the air damper 221 to rotate upward. The heating member 24 above the air damper 221 also plays a limiting role on the air damper 221, such that the maximum upward rotation angle of the air damper 221 does not exceed 90°. In this case, it is preferably set to 70°. This can enable the air damper 221 to automatically return to the horizontal position when the negative pressure is relatively small, preventing the air damper 221 from being stuck by the heating member 24 and unable to reset.
[0061] Through such a setting, on the one hand, it can automatically adjust the opening degree of the air damper 221 according to the magnitude of the negative pressure generated by the circulating air flow during operation, ensuring smooth air intake. The setting of the filter screen can prevent the inhalation of foreign objects; on the other hand, it can block the internal washing foam, prevent the overflow of the laundry foam, and avoid polluting the indoor air.
[0062] Preferably, as Figure 3 and Figure 4 shown, the air duct device of the present invention further includes a filter 4, and the filter 4 is installed at the air inlet of the heat absorption pipe 31 assembly.
[0063] Exemplarily, the filter 4 can be flexibly set as a filter screen, a filter element, etc., which can filter the outside air, prevent the inhalation of external foreign objects, and further improve the cleanliness of the inhaled air.
[0064] In a preferred embodiment, the air duct device further includes a condenser 5. The condenser 5 is installed at the air outlet of the care chamber 1, and can condense the circulating air flow flowing out from the care chamber 1, reduce the humidity in the circulating air flow, and play a role in drying the circulating air flow.
[0065] In addition, the clothing care device further provided by the present invention on the basis of the above technical solution includes the above air duct device, and thus has the technical effects possessed by the above air duct device. Compared with the clothing care device before improvement, the clothing care device of the present invention has higher drying efficiency and use safety.
[0066] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
