Description

Technical Field

[0001] This utility model relates to the field of clothing treatment equipment technology, and more specifically, to a clothing steam care device and a washing machine with steam care function. Background Technology

[0002] To meet people's washing and care needs for different types of clothing, existing garment processing equipment has developed steam washing and care programs. A steam generator is installed in the garment processing equipment, and the clothes are placed inside the drum of the garment processing device. While the drum rotates, high-temperature, high-pressure steam is introduced into the drum to achieve a delicate washing and care effect on the clothes.

[0003] However, most current garment care equipment uses a combination of a water container and a heating element in its steam generator. The heating element heats the water in the container to produce steam, which is then sent into the drum to care for the garments. But achieving steam washing and care requires a large amount of steam, and most existing steam generators suffer from problems such as long steam generation time, insufficient steam output, intermittent steam generation, poor stability, and difficulty in controlling steam temperature, thus failing to achieve the desired garment care effect.

[0004] Chinese invention patent application CN115341366A discloses a clothing treatment device that uses electromagnetic heating to heat water in a water chamber to generate steam. Although this solution has higher energy conversion efficiency and faster heating speed, it still takes a lot of time to directly heat water into steam, resulting in a longer clothing care time. Utility Model Content

[0005] The main objective of this invention is to provide a steam care device for clothing and a washing machine with steam care function to solve the technical problems mentioned in the background art.

And a heating module for heating the mist and / or water entering the air duct, causing the mist and / or water to vaporize into steam, and then discharged from the outlet end of the air duct.

[0007] In the above technical solution, the heating module is further defined as an electric heating wire.

[0008] In any of the above technical solutions, the heating module is further defined as an electromagnetic heating module; The air duct is made of a magnetically conductive metal material, and the electromagnetic heating module is wrapped around the outer wall of the air duct.

[0009] In any of the above technical solutions, a heat insulation layer is further provided between the outer surface of the air duct and the electromagnetic heating module.

[0010] In any of the above technical solutions, the electromagnetic heating module further comprises at least three sets, which are arranged at intervals along the length of the air duct. The water delivery pipe sprays water onto the inner wall of the air duct corresponding to the electromagnetic heating module in the middle area.

[0011] In any of the above technical solutions, further comprising: Several temperature sensors are arranged along the length of the air duct to detect the temperature at the air duct position corresponding to each group of electromagnetic heating modules, and send the detected temperature signal to the control module. And a control module, which individually controls the output power of each electromagnetic heating module based on the received temperature signal.

[0012] In any of the above technical solutions, further comprising: The fan module is located between the atomizing module and the air duct, and is used to guide the mist generated by the atomizing module into the air duct.

[0013] On the other hand, a washing machine with steam care function is also proposed, including: a washing machine body, an inner drum and an outer drum disposed within the washing machine body; and a door for opening and closing the washing machine body; and also including: a steam care device of any of the above.

[0015] In the above technical solution, a humidity sensor is further provided inside the inner cylinder and / or the outer cylinder, and the humidity sensor is electrically connected to the control module.

[0016] Beneficial effects: Compared with existing technologies, The atomizing module first atomizes water into small droplets, which then enter the air duct. Under the action of the heating module, the small droplets are quickly vaporized into steam, which is then discharged from the air duct outlet. This method can effectively improve the steam generation efficiency.

[0017] By heating and vaporizing water and mist, the amount of steam can be adjusted over a wide range. Small amounts of steam are suitable for delicate care, while large amounts of steam are suitable for deep care, covering the needs of multiple scenarios and realizing different care methods.

[0018] By using electromagnetic heating to heat the air duct, the mist inside the air duct can be heated up quickly and reach the vaporization temperature, greatly shortening the steam output time.

[0028] The steam care device and the washing machine with steam care function of this application will be described in detail below through the following embodiments.

[0029] Example 1: like Figure 1As shown, this embodiment proposes a clothing steam care device, including: an atomizing module 1 for generating mist; a water storage chamber 2 for supplying water to the atomizing module 1; an air duct 3, the inlet of which is connected to the mist outlet of the atomizing module 1; a water delivery pipe 4, one end of which is connected to the air duct 3 and the other end of which is connected to the water storage chamber 2, the water storage chamber 2 also being used to supply water to the water delivery pipe 4 so that water is sprayed into the air duct 3; and a heating module for heating the mist and / or water entering the air duct 3, so that the mist and / or water vaporize into steam and are discharged from the outlet of the air duct 3.

[0030] Traditional methods of generating steam by heating water result in a slow steam generation rate. Therefore, this embodiment includes an atomizing module 1, a water storage chamber 2, and a water delivery pipe 4. The atomizing module 1 is a device used to atomize water into small droplets; this is existing technology and will not be described in detail. The atomizing module 1 first atomizes the water into small droplets, which then enter the air duct 3. Under the action of the heating module, the small droplets are quickly vaporized into steam, which is then discharged from the outlet of the air duct 3. This method effectively improves steam generation efficiency.

[0031] Since the amount of mist produced by the atomizing module 1 is limited, a large amount of steam cannot be generated in the air duct 3. Therefore, a water delivery pipe 4 is installed to spray water into the air duct 3, using a built-in pump or valve. In the initial stage of care, a large amount of steam is not needed; simply vaporizing the mist is sufficient. However, in the middle stage of care, a large amount of steam is required. At this time, the water delivery pipe 4 can be opened to spray water into the air duct 3. The water will be vaporized into steam by the heated air duct 3, generating a large amount of steam, which will be discharged through the outlet of the air duct 3. Once the amount of steam is sufficient, the amount of water entering the air duct 3 can be adjusted to regulate the amount of steam.

[0032] Different treatment methods (small amount steam treatment, large amount steam treatment) are achieved by heating and vaporizing water and mist.

[0033] In this embodiment, the heating module can be a heating wire. By heating the heating wire, the mist inside the air duct 3 is heated, causing the mist to vaporize into steam. However, heating with a heating wire is an indirect heating method for the air duct 3, resulting in low thermal efficiency and a slow response speed.

[0034] Therefore, an optimized design employs an electromagnetic heating module 5 as the heating module. The air duct 3 is made of a magnetically conductive metallic material, and the electromagnetic heating module 5 is wound around the outer wall of the air duct 3. An alternating magnetic field is generated by passing an alternating current through an induction coil, causing eddy currents to flow into the magnetically conductive air duct 3 itself, generating heat. This is a direct heating method with a fast response time, enabling the mist inside the air duct 3 to quickly heat up and reach its vaporization temperature, significantly shortening the steam generation time. Furthermore, electromagnetic heating ensures uniform heating of the entire air duct 3 through eddy currents, eliminating the "localized high temperature" phenomenon of heating wires. This prevents the air duct 3 from deforming or being damaged due to localized overheating, while also reducing safety hazards caused by high temperatures and improving the safety of equipment operation.

[0035] It should be noted that a heat insulation layer 6 is provided between the outer surface of the air duct 3 and the electromagnetic heating module 5. By setting the heat insulation layer 6, heat loss from the air duct 3 is prevented, and heat insulation is also achieved.

[0036] In this embodiment, a fan module 9 is also included, disposed between the atomizing module 1 and the air duct 3, for guiding the mist generated by the atomizing module 1 into the air duct 3. The fan module 9 quickly discharges the mist into the air duct 3.

[0037] Example 2: This embodiment is a further improvement based on Embodiment 1.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the electromagnetic heating module 5 has at least two sets, which are arranged at intervals along the length of the air duct 3.

[0039] Because the air duct 3 is relatively long, in order to ensure that the temperature of the steam discharged from the outlet of the air duct 3 can reach the set threshold, the electromagnetic heating module 5 is set up in multiple groups, and each group of electromagnetic heating module 5 is controlled independently.

[0040] The steam treatment device also includes: several temperature sensors 7 arranged along the length of the air duct 3 to detect the temperature of the air duct 3 corresponding to each group of electromagnetic heating modules 5, and send the detected temperature signal to the control module 8; And control module 8, which controls the output power of each group of electromagnetic heating modules 5 individually based on the received temperature signal.

[0041] During the start-up of the steam treatment device, the temperature sensors 7 in the air duct 3 monitor the temperature of each section in the air duct 3 in real time. Then, the control module 8 controls the output power of each electromagnetic heating module 5 according to the temperature signal. When the temperature in a certain section of the air duct 3 is too low, the control module 8 controls the output power of the electromagnetic heating module 5 at that point to increase the temperature, thereby effectively ensuring the temperature of the steam discharged from the outlet of the air duct 3.

[0042] It should be noted that the electromagnetic heating module 5 near the inlet of the air duct 3 needs to have a relatively large output power to heat the mist into steam in order to achieve the vaporization of the mist. The other electromagnetic heating modules 5 (except for the electromagnetic heating module 5 near the outlet of the air duct 3) are used to heat the air duct 3 at a relatively low temperature, just to maintain the surface temperature of the air duct 3 constant, so as to reduce the loss of steam due to condensation on the surface of the air duct 3 during the transportation process, and to ensure the temperature when the steam is discharged.

[0043] Specifically, for the above solution, the electromagnetic heating module 5 can be configured in three sets: one set near the inlet and one set near the outlet of the air duct 3, and another set in the middle area of ​​the air duct 3. The electromagnetic heating module 5 near the inlet of the air duct 3 heats the mist into steam. Then, the electromagnetic heating module 5 in the middle area maintains the temperature of the steam to prevent condensation. Finally, the electromagnetic heating module 5 near the outlet of the air duct 3 heats the steam a second time, increasing the steam temperature and further vaporizing the mist mixed in the steam, thereby effectively improving the purity of the steam.

[0044] It should be noted that the water flowing out of the water delivery pipe 4 is sprayed onto the inner surface of the air duct 3, which is equipped with the electromagnetic heating module 5 in the middle area.

[0045] It should be noted that the garment steam care device operates as follows: Initially, the fan module 9, atomizing module 1, and all electromagnetic heating modules 5 are turned on. The electromagnetic heating module 5 near the inlet of the air duct 3 vaporizes the mist, while the electromagnetic heating module 5 in the middle area is preheated, allowing for rapid steam generation without waiting, although the amount of steam is relatively small. Once the temperature of the electromagnetic heating module 5 in the middle area reaches the set value, the valve / pump is turned on, and water is sprayed onto the inner wall of the air duct 3 of the electromagnetic heating module 5 in the middle area. The water is vaporized to generate a large amount of steam, enhancing the care effect.

[0046] Example 3: like Figure 1 and Figure 2 As shown, this embodiment proposes a washing machine with steam care function, including: a washing machine body 100, an inner drum 110 and an outer drum 120 disposed within the washing machine body 100; and a door 130 for opening and closing the washing machine body 100; wherein, it also includes: the steam care device in any of the above embodiments; The outlet end of the air duct 3 leads to the inner cylinder 110.

[0047] Open the door 130 and put the clothes into the inner drum 110. After the washing machine finishes washing and spinning the clothes, start the steam care device. The atomizing module 1 will atomize the incoming water into small water droplets, which will then be transported to the air duct 3 through the fan module 9. At the same time, the control module 8 controls the electromagnetic heating modules 5 to start, heating the atomized water droplets into steam, which will then be discharged from the outlet of the air duct 3 into the inner drum 110 of the washing machine body 100 to dry and care for the clothes in the inner drum 110.

[0048] It should be noted that an exhaust port 121 is provided on the outer drum 120, and the exhaust port 121 is connected to the inlet end of the air duct 3 through the pipe 122. By setting the exhaust port 121 and the pipe 122, the airflow between the air duct 3, the inner drum 110 and the pipe 122 can circulate, thereby continuously drying and caring for the clothes in the inner drum 110.

[0049] In this embodiment, the inner cylinder 110 and / or the outer cylinder 120 are optimized to be equipped with a humidity sensor 140, which is electrically connected to the control module 8.

[0050] To maintain a constant steam volume and temperature inside the inner cylinder 110, multiple humidity sensors 140 are installed. Based on the feedback data from the temperature sensors 7 and humidity sensors 140, the opening time of the valve / pump and the opening time of the atomization module 1 are dynamically adjusted to regulate the steam generation and keep it constant within a certain range, thus maintaining a constant temperature and humidity inside the inner cylinder 110 as much as possible. After the steam treatment is completed, the atomization module 1, valve / pump, and electromagnetic heating module 5 are turned off, and the air heater or dual-phase heater is turned on to remove the steam inside the inner cylinder 110 through condensation. After the humidity of the inner cylinder 110 drops to the preset value, the air heater or dual-phase heater is turned off, and only the fan module 9 is turned on for cooling. After the temperature of the inner cylinder 110 drops to the preset value, the mode ends.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
