Abstract
Description
Technical Field
[0001] This application relates to the field of clothing drying equipment, and more particularly to a clothing care device. Background Technology
[0002] Heat pump dryers operate through a heat pump system. Compared to traditional condenser or vented dryers, heat pump dryers utilize heat pump technology to recover heat, resulting in higher energy efficiency and effectively reducing energy consumption.
[0003] Heat pump dryers contain a steam generating component that heats water to boiling using electric heating to produce high-temperature steam. This steam is then introduced into the dryer drum, where it comes into contact with the clothes. During the drying process, the steam helps reduce wrinkles, sterilize, and remove odors.
[0004] Due to the power limitation of the heating element, the amount of steam generated by the heating element of the steam generator in existing heat pump dryers is insufficient to meet the requirements for effective ironing of clothes. Utility Model Content
[0005] In view of this, the purpose of this application is to provide a garment care device to solve the technical problem of insufficient steam output from steam generators in the prior art.
[0006] To achieve at least one of the above objectives, this application provides the following technical solution:
[0007] In a first aspect, this application provides a garment care device, comprising: an outer cylinder; an inner cylinder rotatably disposed inside the outer cylinder, the inner cylinder having a processing chamber for accommodating garments; a steam generator, the steam generator comprising: a water pump; a steam generating pipe and a heating element located within the steam generating pipe, the steam generating pipe having a first chamber, at least a portion of the first chamber spirally surrounding the outer periphery of the heating element along the extending direction of the heating element; the first chamber being provided with a water inlet and a steam outlet, the water inlet being connected to the outlet of the water pump, enabling the water pump to deliver water into the first chamber through the water inlet, the heating element heating the water in the first chamber to generate steam flowing towards the steam outlet; and a steam flow pipe, the lower end of which is connected to the steam outlet to allow steam to enter the steam flow pipe, and the upper end of which is connected to a nozzle for spraying steam toward the processing chamber.
[0008] In the above technical solution, by setting the inside of the inner drum as a processing chamber, clothes can be dried after being placed in the processing chamber. During the drying process, the inner drum can be driven to rotate, which helps to dry the clothes quickly and evenly.
[0009] The steam generator allows steam to be sprayed into the drying chamber while clothes are being dried. The steam irons the clothes, giving them a smooth finish after drying. The high-temperature steam also sterilizes and disinfects the clothes, effectively killing bacteria, mites, and viruses.
[0010] Water is pumped into the steam generating pipe through the inlet. The water flows in a spiral shape towards the steam outlet. As the water flows in the steam generating pipe, it comes into contact with the heating element, which heats the water and turns it into steam. The steam then flows out from the steam outlet into the steam circulation pipe.
[0011] Because of the spiral flow of water in the pipe, the contact time between the water and the heating element is longer than the contact time when the water flows smoothly in a straight line, and the water absorbs more heat, thus generating more steam.
[0012] Water flows in a spiral pattern within the steam generating pipe, which mixes the water and makes the water temperature basically uniform. When the water flows to the position near the steam outlet, the unvaporized water is at a higher temperature and is more likely to generate steam when it comes into contact with the heating element. This reduces or avoids the situation where some water is too cold and has a short contact time with the heating element, thus failing to vaporize and generate steam, thereby increasing the amount of steam entering the steam flow pipe.
[0013] Steam enters the steam flow pipe from the lower end and flows towards the nozzle at the upper end. As the steam flows in the steam flow pipe, some of the steam liquefies into water and flows back into the steam generation pipe and contacts the heating element under its own gravity. This reduces or avoids water mixed in with the steam sprayed from the nozzle, preventing water from entering the processing chamber and contacting the clothes, thus affecting the drying of the clothes.
[0014] In some embodiments, the first chamber is formed by the outer side of the heating element and the inner wall of the steam generating pipe.
[0015] In the above technical solution, the first chamber is located on the outer periphery of the heating element. When water flows in the first chamber, the water directly contacts the side of the heating element, thereby achieving the heating of the water by the heating element.
[0016] The first chamber is located on the steam generating pipe, which simplifies the structure of the heating element and reduces its production cost compared to placing it on the heating element.
[0017] In some embodiments, the steam generating pipe further includes a second chamber, which accommodates and is completely filled by the heating element; the heating element is a heating tube, with its two ends extending out of the steam generating pipe and electrically connected to the two ends of a wire.
[0018] In the above technical solution, the steam generating pipe is divided into two chambers: a second chamber and a first chamber. The heating element is set as a pipe, with one end passing through and extending out of the steam generating pipe, which enables the installation of the heating element and the steam generating pipe. The heating element has a simple structure, and the two ends of the heating element used for electrical connection with the wire are located outside the steam generating pipe, which helps to improve the safety of the heating element.
[0019] In some embodiments, the steam generating pipe is a pipe with its centerline arranged in a horizontal direction.
[0020] In the above technical solution, by setting the steam generating pipe in a horizontal direction, the water flows in a spiral direction inside the steam generating pipe and also tumbles up and down, which makes the water mix more evenly.
[0021] The up-and-down movement of water can disrupt the steam membrane formed when water comes into contact with the heating element. This steam membrane hinders the contact and heat transfer between the water and the heating element. The up-and-down movement of water can increase the contact time between the water and the heating element and increase the amount of steam.
[0022] In some embodiments, the steam outlet is located above the steam generating pipe.
[0023] In the above technical solution, by setting the steam outlet connected to the steam flow pipe above the steam generating pipe, when liquid water appears in the steam flow pipe, the liquid water can flow back into the steam generating pipe from the steam outlet, re-contact the heating element, and vaporize again.
[0024] It helps reduce the accumulation of liquid water in the steam flow pipes and helps reduce the amount of liquid water in the steam injected into the processing chamber from the nozzle, which facilitates the drying of clothes inside the processing chamber.
[0025] In some embodiments, the steam generator further includes a pressure relief valve connected to a steam generation pipeline, which opens when the pressure in the steam generation pipeline exceeds a set value.
[0026] In the above technical solution, by connecting a pressure relief valve to the steam generating pipeline, when the nozzle, steam flow pipeline or steam generating pipeline is blocked and steam cannot be discharged from the steam generating pipeline in time, the pressure in the steam generating pipeline increases. When the set pressure is reached, the pressure relief valve opens, and the pressure in the steam generating pipeline can be discharged through the pressure relief valve, which helps to improve the safety of the steam generator.
[0027] In some embodiments, the steam generator further includes: a water tank disposed at the bottom of the garment care device; a water inlet pipe, one end of which is connected to the water tank and the other end of which is connected to the inlet of the water pump; and a pressure relief pipe, one end of which is connected to a pressure relief valve and the other end of which is connected to the water tank, wherein when the pressure relief valve is opened, water can enter the pressure relief pipe and be discharged into the water tank.
[0028] In the above technical solution, water is supplied to the steam generator through a water tank. After the water pump is turned on, the water pump draws water from the water tank through the water inlet pipe, pressurizes it, and sends it into the steam generation pipeline, thereby delivering water into the steam generation pipeline. Since the water tank is located at the bottom of the clothing care equipment, when the water pump draws water from the water tank, the water is sent into the steam generation pipeline by the pressure of the water pump.
[0029] By controlling the water pump pressure, the amount of water delivered into the steam generating pipe can be controlled. This avoids the water volume being affected by gravity when the water tank is located above the garment care equipment, which helps to accurately control the amount of water entering the steam generating pipe. The heating element heats the water into steam and discharges it from the steam outlet, preventing excessive water from entering the steam generating pipe and causing the steam to contain liquid water.
[0030] When the pressure in the steam generating pipeline is too high, the water in the steam generating pipeline flows back into the water tank through the pressure relief valve and the pressure relief water pipe, thus avoiding the waste of water by directly discharging the water in the steam generating pipeline.
[0031] In some embodiments, the steam generator further includes an insulating outer shell, which is fitted over the outside of the steam generating pipe.
[0032] In the above technical solution, by setting up an insulation shell, the heat transfer from the water to the steam generating pipe and then the heat loss from the steam generating pipe when the water is heated in the steam generating pipe can be reduced, which helps to improve heating efficiency and increase steam output.
[0033] The insulation shell, by wrapping the steam generating pipe, can protect the outside of the steam generating pipe and increase its explosion-proof properties.
[0034] In some embodiments, the steam generator further includes a protective housing that is fitted over the outside of the water pump and the steam generation pipe.
[0035] In the above technical solution, by covering the water pump and steam generating pipe with a protective shell, the water pump and steam generating pipe are protected, and the water pump and steam generating pipe are separated from other parts of the garment care equipment, so as to avoid the vibration and temperature generated by the steam generator during use from affecting other parts of the garment care equipment.
[0036] In some embodiments, a heat insulation sleeve is provided on the outside of the steam flow pipe.
[0037] In the above technical solution, by installing a heat insulation sleeve on the outside of the steam flow pipe, the heat loss of the steam flow pipe can be reduced, the condensation of steam into liquid water in the steam flow pipe can be reduced, and the amount of steam injected into the treatment chamber from the nozzle can be increased.

It should be understood that the thickness, length, and other dimensions of various components in the embodiments of this application shown in the drawings, as well as the overall thickness, length, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.
[0068] As part of the inventive concept of this application, before describing the embodiments of this application, it is necessary to analyze the reasons for the problem of insufficient steam generation by steam generators in related technologies, and obtain the technical solution of the embodiments of this application through reasonable analysis.
[0069] In related technologies, garment care equipment sprays high-temperature steam onto clothes during the drying process, which can reduce wrinkles, sterilize and disinfect, and remove odors.
[0070] High-temperature steam softens clothing fibers, making clothes easier to stretch and reducing wrinkles. Clothes are generally smoother after drying, requiring minimal ironing.
[0071] The high temperature of steam can effectively kill bacteria, mites, and viruses on clothing. At the set steam temperature and time, a high sterilization rate is achieved, making clothing healthier to wear.
[0072] Steam can also penetrate into the fabric fibers, carrying away odor molecules that have been absorbed into the fabric, leaving the clothes with a fresh scent.
[0073] Taking a heat pump dryer as an example, a heat pump dryer uses heat pump technology to cool the air through a refrigeration system, causing the moisture in the air to condense into water droplets and be discharged. Then, the dry air is heated and sent back into the drying drum, and the cycle is repeated to dry the clothes.
[0074] A heat pump dryer includes a heat pump system, a ventilation system, a steam generation system, and a control system.
[0075] The heat pump system condenses and discharges moisture from the air through a refrigeration cycle, while simultaneously heating the dried air to provide a drying heat source for clothes drying, achieving the purpose of energy saving and low-temperature drying.
[0076] The ventilation system circulates air within the dryer, delivering humid air to the heat pump system for dehumidification and heating, and then returning the dry, hot air to the drying drum to dry the clothes. At the same time, it maintains smooth airflow inside the dryer and preserves a suitable drying environment.
[0077] The steam generation system works in conjunction with the heat pump system and ventilation system. At the beginning of the drying process, the heat pump system first removes most of the moisture from the clothes by heating the air. Once the clothes have reached a certain level of dryness, the steam generator starts working, releasing steam to further treat the clothes.
[0078] After steam treatment is complete, the heat pump system continues to operate, thoroughly drying any remaining moisture in the clothes. This synergistic operation allows for rapid drying of clothes, leveraging the various advantages of steam to maintain their quality and appearance while drying.
[0079] The control system controls parameters such as the dryer's operating mode, time, temperature, and humidity to achieve an intelligent drying process, meeting the drying needs of different clothes and ensuring the safe and stable operation of the dryer.
[0080] The steam generating system includes a heating element, a water tank, and steam nozzles. The heating element, such as a resistance wire or other heating device, converts electrical energy into heat energy to heat the water. The water tank stores the water needed to generate steam. The steam nozzles are located inside the dryer's outer drum and evenly spray the generated steam onto the clothes.
[0081] The power of the heating element affects the speed and amount of steam generated. Due to the power limitations of garment care equipment, the power of the heating element has an upper limit.
[0082] Once the power of the heating element is determined, although theoretically it can generate a corresponding amount of steam to be ejected from the nozzle, in reality, the amount ejected from the nozzle is less than the corresponding amount of steam. The heating element cannot heat all the water into steam. Insufficient steam generation by the steam generating system affects the steam's effectiveness in ironing, sterilizing, and deodorizing clothing.
[0083] Liquid water was also found in the steam emitted from the nozzle. After analysis, the inventor concluded that the heat exchange between the water and the heating element was insufficient. The heating element only heated part of the water into steam and emitted it from the nozzle, while some water was not hot enough and remained in the form of liquid water.
[0084] Therefore, this application provides a garment care device, including an outer cylinder and an inner cylinder rotatably disposed inside the outer cylinder, the inner cylinder having a processing cavity capable of accommodating garments.
[0085] A steam generator includes: a water pump; a steam generating pipe and a heating element located within the steam generating pipe, the steam generating pipe having a first chamber, at least a portion of the first chamber spirally surrounding the outer periphery of the heating element along the extending direction of the heating element.
[0086] The first chamber is equipped with a water inlet and a steam outlet. The water inlet is connected to the outlet of the water pump, so that the water pump can send water into the first chamber through the water inlet. The heating element heats the water in the first chamber to generate steam that flows to the steam outlet.
[0087] The lower end of the steam flow pipe is connected to the steam outlet to allow steam to enter the steam flow pipe, and the upper end is connected to a nozzle, which is used to spray steam toward the processing chamber, thereby solving the technical problem of insufficient steam generated by the steam generator in the existing garment care equipment.
[0088] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0089] For ease of explanation, a first direction, a second direction, and a third direction are defined, where the first direction is the thickness direction of the garment care device, the second direction is the width direction of the garment care device, and the third direction is the height direction of the garment care device when it is normally placed. In the attached drawings, the first direction is represented by the X direction, the second direction by the Y direction, and the third direction by the Z direction.
[0090] Figure 1 A three-dimensional structural diagram of a garment care device is provided. Specifically, the garment care device also includes a housing 1, which is the outer shell of the garment care device. The housing 1 has a hollow rectangular structure, and the shape of the housing 1 can be designed as needed, without limitation.
[0091] Reference Figure 2 The housing 1 is provided with a receiving cavity, which can provide installation space for components such as the outer cylinder 2, the inner cylinder 4, and the drying air duct 5.
[0092] Reference Figure 1 The container 1 is provided with a dispensing port 11, which is roughly circular and located at the front end of the container 1. The dispensing port 11 is connected to the receiving cavity.
[0093] A door 12 is installed on the housing 1. The door 12 is hinged to the housing 1 near the dispensing port 11. The door 12 can rotate to close the dispensing port 11. The door 12 can rotate away from the dispensing port 11 to open the dispensing port 11. When the clothing care equipment is running, the door 12 closes the dispensing port 11.
[0094] Reference Figure 2 The outer cylinder 2 is located inside the receiving cavity of the box body 1. The outer cylinder 2 is a shell structure with an open front end. The opening at the front end of the outer cylinder 2 is the first cylinder opening, which is connected to the inner cavity of the outer cylinder 2 and is positioned opposite to the delivery port 11.
[0095] Reference Figure 2 Specifically, the outer cylinder 2 can be formed by an outer peripheral wall 22 and a rear end wall 21. The outer peripheral wall 22 is a cylindrical structure, and a first cylinder opening is provided at the front end of the outer peripheral wall 22. The rear end wall 21 is sealed and fixed to the rear end of the outer peripheral wall 22, and the rear end wall 21 is arranged opposite to the first cylinder opening.
[0096] An air vent is provided on the rear wall 21, which is connected to the drying air duct 5. The gas in the inner cavity of the outer cylinder 2 flows into the drying air duct 5 through the air vent.
[0097] A door seal ring 13 is also provided between the first cylinder opening and the inlet 11. The door seal ring 13 is roughly in the shape of a circular ring and can seal the gap between the first cylinder opening and the inlet 11 to prevent water in the outer cylinder 2 from flowing into the receiving cavity of the tank 1.
[0098] Reference Figure 2 In this embodiment, the inner cylinder 4 is disposed in the inner cavity of the outer cylinder 2. The inner cylinder 4 is rotatably connected to the rear end wall 21 of the outer cylinder 2 via a rotating shaft 42. The rotating shaft 42 passes through the rear end wall 21 from front to back, and the inner cylinder 4 and the outer cylinder 2 are arranged coaxially inside and outside.
[0099] Specifically, the inner tube 4 is a shell structure with an open front end. A processing cavity 41 is formed inside the inner tube 4. The processing cavity 41 can hold clothing. The opening at the front end of the inner tube 4 is a second tube opening. The second tube opening is connected to the processing cavity 41, and the second tube opening and the first tube opening are spaced apart along a first direction.
[0100] After the door 12 is opened, clothing can be put into or taken out of the processing chamber 41 through the inlet 11, the first cylinder inlet and the second cylinder inlet.
[0101] The inner cylinder 4 includes a first cavity, which is the cavity between the inner cylinder 4 and the outer cylinder 2. A through hole is provided on the side peripheral wall of the inner cylinder 4, which allows the processing cavity 41 to communicate with the first cavity.
[0102] Since the air vent on the rear wall 21 is exposed in the first cavity, the processing cavity 41 can be connected to the air vent via the first cavity.
[0103] In this embodiment, refer to Figure 2 The drying air duct 5 is located outside the outer cylinder 2. The drying air duct 5 has a return air inlet and an air outlet. Along the first direction, one end of the drying air duct 5 is the return air inlet and the other end is the air outlet. The return air inlet is located at the rear end of the outer cylinder 2 and communicates with the first cavity, while the air outlet is located at the front end of the outer cylinder 2 and communicates with the processing cavity 41.
[0104] In this embodiment, the drying air duct 5 is connected to the processing chamber 41 in the following way: the drying air duct 5 passes through the door seal ring 13 along the first direction toward the front end of the door body 12.
[0105] The return air inlet is connected to the air outlet on the rear end wall 21, and the air outlet is connected to the processing chamber 41, so that the processing chamber 41, the first chamber, and the drying air duct 5 can form an air drying circulation loop.
[0106] The drying duct 5 is configured to supply gas for drying clothes into the processing chamber 41 and to extract gas from the first chamber through the return air vent.
[0107] Reference Figure 2 as well as Figure 4Specifically, a heating device 51 and a fan 52 are installed inside the drying duct 5. The heating device 51 is configured to heat the air inside the drying duct 5 and increase the temperature of the air inside the drying duct 5.
[0108] The fan 52 is used to provide airflow so that air enters the drying duct 5 through the air inlet on the rear end wall 21, and the high-temperature air in the drying duct 5 can enter the processing chamber 41 of the inner cylinder 4. The hot air in the processing chamber 41 dries the clothes in the processing chamber 41.
[0109] Reference Figure 2 In this embodiment, the garment care device also includes a condenser 6, which is disposed on the side of the rear end wall 21 facing the inner cylinder 4.
[0110] In another embodiment, the condenser 6 may be located in other positions as needed.
[0111] The condenser 6 cools the air flowing from the inner cavity of the outer cylinder 2 through the air inlet of the rear end wall 21 into the drying air duct 5, causing the water vapor in the hot and humid air to condense into liquid water, thereby dehumidifying the air flowing through the condenser 6 and making the air entering the drying air duct 5 relatively dry.
[0112] When the garment care equipment is working, the air in the first chamber exchanges heat with the condenser 6, which lowers the air temperature and removes moisture from the air. Then, the air enters the drying duct 5 from the return air vent.
[0113] Specifically, the air is heated by the heating device 51 in the drying air duct 5, and the high temperature air in the drying air duct 5 enters the processing chamber 41, heating the clothes in the processing chamber 41, taking away the moisture on the clothes, and forming hot and humid air.
[0114] Hot and humid air enters the first cavity through the through hole on the inner cylinder 4 and can flow through the condenser 6. The hot and humid air comes into contact with the condenser 6 to exchange heat, so that the moisture in the hot and humid air condenses on the condenser 6.
[0115] After being condensed and dehumidified by the condenser 6, the air enters the drying duct 5 through the return air inlet and is reheated to realize the drying cycle of the garment care equipment. After multiple cycles, the clothes can be dried.

[0119] The first chamber 64 is provided with a water inlet 61 and a steam outlet 62. The water inlet 61 is connected to the outlet of the water pump 91, so that the water pump 91 can send water into the first chamber 64 by sending water into the water inlet 61.
[0120] The heating element 7 is located inside the steam generating pipe 6. The heating element 7 heats the water inside the steam generating pipe 6 to generate steam that flows to the steam outlet 62.
[0121] The lower end of the steam flow pipe 8 is connected to the steam outlet 62 to allow steam to enter the steam flow pipe 8, and the upper end is connected to a nozzle 81, which is used to spray steam toward the processing chamber 41.
[0122] Reference Figure 6 The water pump 91 is a device used to draw water and pressurize it. The water pump 91 has an inlet and an outlet. The inlet of the water pump 91 is connected to a water source, which can be a municipal water pipe or a water storage tank 92 on the clothing care device. In this embodiment, the inlet of the water pump 91 is connected to the water storage tank 92.
[0123] The outlet of water pump 91 is connected to steam generating pipeline 6. On the one hand, the outlet of water pump 91 can be directly connected to steam generating pipeline 6. On the other hand, a pipeline is provided between the outlet of water pump 91 and steam generating pipeline 6 for connection. More specifically, various valves, such as check valves and pressure relief valves, can be installed between the outlet of water pump 91 and steam generating pipeline 6 according to design requirements.
[0124] When the water pump 91 is running, the inlet of the water pump 91 draws water, and the outlet of the water pump 91 outputs water at a set pressure and flow rate into the steam generating pipeline 6, thereby supplying water to the steam generating pipeline 6.
[0125] Reference Figure 6 and Figure 7The steam generating pipe 6 has a water inlet 61 and a steam outlet 62. The water inlet 61 and the steam outlet 62 are respectively located at the two ends of the outer side of the steam generating pipe 6. The water inlet 61 and the steam outlet 62 of the steam generating pipe 6 are connected through the first chamber 64.
[0126] The inlet 61 is connected to the outlet of the water pump 91, and the steam outlet 62 is connected to the steam flow pipe 8. Water pumped from the water pump 91 into the inlet 61 flows towards the steam outlet 62 in the first chamber 64. Water enters the first chamber 64 from the inlet 61 and flows towards the steam outlet 62 within the first chamber 64.
[0127] It should be noted that the flow towards the steam outlet 62 here only indicates the overall flow trend of the water. When the water flows towards the steam outlet 62, there will also be a spiral flow around the center line of the steam generating pipe 6, as well as a centrifugal flow away from the steam generating pipe 6.
[0128] Reference Figure 8 The heating element 7 is located inside the steam generating pipe 6. The heating element 7 heats the water in the first chamber 64 to generate steam that flows to the steam outlet 62.
[0129] When the heating element 7 is energized, it converts electrical energy into heat energy, causing the temperature of the heating element 7 to rise. When water comes into contact with the heating element 7, the heating element 7 heats the water, raising its temperature and ultimately generating steam.
[0130] In this embodiment, the electrodes of the heating element 7, which are connected to the circuit, are located outside the steam generating pipe 6. The centerline of the heating element 7 is arranged along the centerline of the steam generating pipe 6, and the two ends of the heating element 7 are respectively located on the outer sides of the two ends of the steam generating pipe 6. The heating element 7 itself can seal the two ends of the steam generating pipe 6, so that a closed cavity is constructed inside the steam generating pipe 6.
[0131] In another embodiment, the electrodes of the heating element 7 for connection with the circuit are located inside the steam generating pipe 6, and both ends of the steam generating pipe 6 are closed. The electrodes of the heating element 7 and the outer side of the wires are covered with insulating materials to avoid short circuits caused by water being electrified.
[0132] Due to the installation of the heating element 7, after water enters the steam generating pipe 6 from the inlet 61, the water flowing towards the steam outlet 62 comes into contact with the heating element 7. The water flows a longer distance in the first chamber 64 than the water flows directly in the straight pipe. The water flows in a spiral state in the first chamber 64, and the heating element 7 can fully heat the water, so that the end of the water in the first chamber 64 becomes steam, and the steam flows out from the steam outlet 62.
[0133] Reference Figure 5 and Figure 6The lower end of the steam flow pipe 8 is connected to the steam outlet 62 to allow steam to enter the steam flow pipe 8. The upper end of the steam flow pipe 8 is connected to a nozzle 81, which is used to spray steam toward the processing chamber 41.
[0134] The steam flow pipe 8 is set vertically, and the lower end of the steam flow pipe 8 is connected to the steam outlet 62 and the lower end of the steam flow pipe 8 is connected to the first chamber 64.
[0135] Steam in the first chamber 64 flows out from the steam outlet 62 into the steam flow pipe 8 and flows upward within the steam flow pipe 8.
[0136] When liquid water is present in the steam entering the steam flow pipe 8 from the steam outlet 62, or when liquid water condenses in the steam in the steam flow pipe 8 due to heat release, the liquid water in the steam flow pipe 8 can flow to the lower end of the steam flow pipe 8 under its own gravity, which helps the water in the steam flow pipe 8 to re-enter the first chamber 64 and come into contact with the heating element 7, and be heated into steam again by the heating element 7.
[0137] Reference Figure 3 and Figure 4 The nozzle 81 is fixed to the outer cylinder 2 and faces the inner cylinder 4. The steam ejected from the nozzle 81 can enter the processing chamber 41 of the inner cylinder 4 to iron, sterilize and remove odors from the clothes inside the processing chamber 41.
[0138] By setting the inside of the inner drum 4 as a processing chamber 41, clothes can be dried after being placed in the processing chamber 41. During the drying process, the inner drum 4 can be driven to rotate, which helps the clothes to dry quickly and evenly.
[0139] By setting up a steam generator, steam can be sprayed into the processing chamber 41 when clothes are being dried. The steam can iron the clothes, giving them a smoother finish after drying. The high-temperature steam can also sterilize and disinfect the clothes, effectively killing bacteria, mites, and viruses.
[0140] Water is pumped into the first chamber 64 through the inlet 61 by the water pump 91. The water flows in a spiral shape towards the steam outlet 62 in the first chamber 64. When the water flows in the first chamber 64, it comes into contact with the heating element 7. The heating element 7 heats the water and turns it into steam, so that steam flows out from the steam outlet 62 to the steam circulation pipe 8.
[0141] Because of the spiral flow of water in the pipe, the contact time between the water and the heating element 7 is longer than the contact time when the water flows smoothly in a straight line, and the water absorbs more heat, thus generating more steam.
[0142] Water flows in a spiral pattern within the steam generating pipe 6, which mixes the water and makes the water temperature basically uniform. When the water flows to the position near the steam outlet 62, the unvaporized water has a higher temperature and is more likely to generate steam when it comes into contact with the heating element 7. This reduces or avoids the situation where some water has a lower temperature and a shorter contact time with the heating element 7, thus failing to vaporize and generate steam, thereby increasing the amount of steam entering the steam flow pipe 8.
[0143] Steam enters the steam flow pipe 8 from the lower end and flows towards the nozzle 81 from the upper end of the steam flow pipe 8. When the steam flows in the steam flow pipe 8, some of the steam liquefies into water and can flow back to the first chamber 64 under its own gravity to contact the heating element 7, thereby reducing or avoiding water mixed in with the steam sprayed from the nozzle 81, and preventing water from entering the processing chamber 41 and contacting the clothes, thus affecting the drying of the clothes.
[0144] Reference Figure 8 As an alternative, the first chamber 64 is formed by the outer side of the heating element 7 and the inner wall of the steam generating pipe 6.
[0145] For example, the steam generating pipe 6 includes a second chamber 63 and a first chamber 64. The first chamber 64 is spirally disposed outside the second chamber 63 and communicates with the second chamber 63. Water supplied from the water pump 91 to the inlet 61 flows in the first chamber 64 toward the steam outlet 62.
[0146] The inner cavity of the steam generating pipe 6 is hollow, dividing the inner cavity of the steam generating pipe 6 into two parts, namely a second chamber 63 and a first chamber 64 that are interconnected. The first chamber 64 is located outside the second chamber 63, and the first chamber 64 is a spiral-shaped cavity extending along the center line of the steam generating pipe 6.
[0147] The first chamber 64 is located on the outer periphery of the heating element 7. When water flows in the first chamber 64, the water directly contacts the side of the heating element 7, thereby achieving rapid heating of the water by the heating element and causing the water to vaporize.
[0148] The first chamber 64 is constructed on the steam generating pipe 6, which simplifies the structure of the heating element 7 and reduces its production cost compared to setting it on the heating element 7.
[0149] Reference Figure 8 As an alternative, the second chamber 63 is used to accommodate the heating element 7 and is completely filled by the heating element 7.
[0150] The heating element 7 is a component that completely fills the second chamber 63. The fact that the heating element 7 completely fills the second chamber 63 ensures that the water entering the steam generating pipe 6 can only flow in the first chamber 64, so that the flow distance of all liquid water entering the steam generating pipe 6 is relatively long, avoiding the situation where some liquid water flows directly to the steam outlet 62 in a straight line and cannot be completely vaporized.
[0151] In this embodiment, the second chamber 63 is a cylindrical chamber. In another embodiment, the second chamber 63 may be a square chamber.
[0152] The first chamber 64 is constructed on the inner wall of the steam generating pipe 6, and the two ends of the first chamber 64 are located one-to-one between the two ends of the steam generating pipe 6 along the first direction. The two ends of the first chamber 64 correspond one-to-one with the water inlet 61 and the steam outlet 62, respectively.
[0153] By dividing the steam generating pipe 6 into two chambers, a second chamber 63 and a first chamber 64, the second chamber 63 is contained and completely filled by the heating element 7, and the first chamber 64 is located outside the heating element 7. When water flows in the first chamber 64, the water comes into contact with the side of the heating element 7, thereby heating the water by the heating element 7.
[0154] The heating element 7 is a heating tube, and the two ends of the heating tube extend out of the two ends of the steam generating pipe 6 and are electrically connected to the wires.
[0155] For example, the heating element 7 is a cylindrical heating tube, with both poles of the heating element 7 extending out of the steam generating pipe 6, and the two poles of the heating element 7 being electrically connected to the positive and negative poles of the power supply respectively.
[0156] The outer wall of the steam generating pipe 6 has a spiral protrusion 65, and a cavity is provided inside the steam generating pipe 6 so that the wall thickness of the steam generating pipe 6 is basically equal at all points.
[0157] To facilitate understanding of the steam generating pipe 6, its structure can be understood as a component similar to threaded steel. The position on the inner wall of the steam generating pipe 6 corresponding to the spiral protrusion 65 can be understood as a spiral groove, and the spiral groove and the outer structure of the heating pipe form the first chamber 64.
[0158] By setting the heating element 7 as a pipe, with one end of the heating element 7 passing through and extending out of the steam generating pipe 6, the installation of the heating element 7 and the steam generating pipe 6 can be realized. The heating element 7 has a simple structure, and the two ends of the heating element 7 used for electrical connection with the wire are located outside the steam generating pipe 6, which helps to improve the safety of the use of the heating element 7.
[0159] Reference Figure 6As an alternative, steam generation pipe 6 is a pipe with its centerline set horizontally.
[0160] By setting the steam generating pipe 6 horizontally, the water flows in a spiral direction inside the steam generating pipe 6, and the water also tumbles up and down to a certain extent, which can make the water mix more evenly inside.
[0161] The up-and-down tumbling of water can disrupt the steam membrane generated when water comes into contact with the heating element 7. This steam membrane hinders the contact and heat transfer between the water and the heating element 7. The up-and-down tumbling of water can increase the contact time between the water and the heating element 7 and increase the amount of steam.
[0162] Reference Figure 6 as well as Figure 7 As an alternative, the steam outlet 62 is located above the steam generating pipe 6.
[0163] Steam outlet 62 is located above steam generating pipe 6, that is, the center line of steam outlet 62 is vertical and located above steam generating pipe 6, and steam outlet 62 is connected to the lowest point of the lower end of steam flow pipe 8.
[0164] In another embodiment, when the steam generating pipe 6 is placed at an angle, the steam outlet 62 is located at the highest point of the steam generating pipe 6.
[0165] The steam outlet 62, which is connected to the steam flow pipe 8, is located above the steam generating pipe 6. When liquid water appears in the steam flow pipe 8, the liquid water can flow back into the first chamber 64 from the steam outlet 62, re-contact with the heating element 7, and vaporize again. This helps to reduce the accumulation of liquid water in the steam flow pipe 8 and helps to reduce the amount of liquid water in the steam sprayed into the processing chamber 41 from the nozzle 81, which facilitates the drying of clothes in the processing chamber 41.
[0166] Reference Figure 6 As an optional solution, the steam generator also includes a pressure relief valve 94, which is connected to the steam generation pipeline 6 and opens when the pressure in the steam generation pipeline 6 exceeds a set value.
[0167] For example, the pressure relief valve 94 is connected to the steam generating pipeline 6 via a pipeline. In this embodiment, the pressure relief valve 94 is located in the pipeline between the steam generating pipeline 6 and the water pump 91.
[0168] In another embodiment, the pressure relief valve 94 is connected to the end of the steam generating pipe 6 and is located between the steam generating pipe 6 and the steam flow pipe 8.
[0169] Specifically, a three-way valve is installed between the water pump 91 and the steam generating pipeline 6, and the interface of the three-way valve is connected to the water pump 91, the steam generating pipeline 6 and the pressure relief valve 94 respectively.
[0170] By connecting a pressure relief valve 94 to the steam generating pipeline 6, when the nozzle 81, steam flow pipeline 8, or steam generating pipeline 6 is blocked, and steam cannot be discharged from the steam generating pipeline 6 in time, the pressure in the steam generating pipeline 6 increases. When the set pressure is reached, the pressure relief valve 94 opens, and the pressure in the steam generating pipeline 6 can be discharged through the pressure relief valve 94.
[0171] This helps improve the safety of steam generator use and prevents safety accidents such as the bursting of connecting pipes under high steam pressure.
[0172] Reference Figure 6 As an optional feature, the steam generator also includes a water tank 92, a water inlet pipe 93, and a pressure relief pipe 95.
[0173] A water tank 92 is located at the bottom of the garment care equipment. One end of the water inlet pipe 93 is connected to the water tank 92, and the other end is connected to the inlet of the water pump 91. A pressure relief pipe 95 is connected at one end to a pressure relief valve 94, and the other end is connected to the water tank 92. When the pressure relief valve 94 is opened, water enters the pressure relief pipe 95 and is discharged into the water tank 92.
[0174] For example, the water tank 92 is located at the lowest point of the steam generator. The user can add water to the water tank 92 through the holes inside the water storage box at the top and the related pipes. If the moisture inside the clothes cannot be contained in the water storage box during the drying process, it can also overflow into the water tank 92 through the related pipes.
[0175] Water is supplied to the steam generator through the water tank 92. After the water pump 91 is turned on, the water pump 91 draws water from the water tank 92 through the water inlet pipe 93, pressurizes it and sends it into the first chamber 64, thereby delivering water to the steam generating pipe 6. Since the water tank 92 is located at the bottom of the clothing care equipment, when the water pump 91 draws water from the water tank 92, the water is sent into the first chamber 64 by the pressure of the water pump 91.
[0176] By controlling the pressure of the water pump 91, the amount of water delivered to the first chamber 64 can be controlled. This avoids the water volume being affected by gravity when the water tank 92 is located above the garment care equipment. This helps to accurately control the amount of water entering the first chamber 64. The heating element 7 heats the water into steam and discharges it from the steam outlet 62, preventing excessive water from entering the first chamber 64 and causing the steam to contain liquid water.
[0177] When the pressure in the steam generating pipe 6 is too high, the water in the first chamber 64 flows back into the water tank 92 through the pressure relief valve 94 and the pressure relief pipe 95, thus avoiding the waste of water by directly discharging the water in the first chamber 64.
[0178] Reference Figure 6As an optional solution, the steam generator also includes an insulation shell 96, which is fitted over the outside of the steam generating pipe 6.
[0179] For example, the insulation shell 96 is a rectangular shell, and it is fitted over the outside of the steam generating pipe 6. In this embodiment, one end of the steam generating pipe 6, which has a water inlet 61, extends out of the insulation shell 96, and the lower end of the steam flow pipe 8 extends deep into the insulation shell 96 and communicates with the steam outlet 62. (See attached...) Figure 6 The cross-section of the central insulation shell 96 is marked using a section line.
[0180] By incorporating an insulating outer shell 96, the heat transfer from the water to the steam generating pipe 6 and then from the steam generating pipe 6 during water heating can be reduced, thus improving heating efficiency and increasing steam output. The insulating outer shell 96 is a plastic shell with added flame retardant.
[0181] The insulating outer shell 96 protects the steam generating pipe 6, as well as the outside of the steam generating pipe 6, and increases the explosion-proof performance of the steam generating pipe 6. The insulating outer shell 96 prevents the outer shell from being burned or ignited by heat transferred from inside the steam generating device.
[0182] Reference Figure 6 As an optional feature, the steam generator also includes a protective housing 97, which is fitted over the water pump 91 and the steam generating pipe 6.
[0183] For example, the lower end of the steam flow pipe 8 passes through the protective housing 97 and the insulation housing 96 and then connects to the steam generating pipe 6. The end of the water inlet pipe 93 away from the water tank 92 passes through the protective housing 97 and then connects to the water pump 91, and the end of the discharge pipe away from the water tank 92 passes through the protective housing 97 and connects to the pressure relief valve 94.
[0184] The protective housing 97 is installed on the outside of the water pump 91 and the steam generating pipe 6, which protects the water pump 91 and the steam generating pipe 6 and separates the water pump 91 and the steam generating pipe 6 from other parts of the garment care equipment, so as to prevent the vibration and temperature generated by the steam generator during use from affecting other parts of the garment care equipment.
[0185] Reference Figure 6 As an optional solution, the steam flow pipe 8 is fitted with a heat insulation sleeve 82.
[0186] Specifically, the steam flow pipe 8 is a high-temperature resistant pipe. For example, the steam flow pipe 8 is a silicone pipe.
[0187] The heat insulation sleeve 82 is a component that is fitted onto the outside of the steam flow pipe 8. For example, the heat insulation sleeve 82 is a heat insulation tape wrapped around the outside of the steam flow pipe 8.
[0188] In another embodiment, the insulation sleeve 82 is a polyurethane foam tube. Alternatively, the insulation sleeve 82 is a glass wool tube.
[0189] By installing the heat insulation sleeve 82 on the outside of the steam flow pipe 8, the heat loss of the steam flow pipe 8 can be reduced, the condensation of steam in the steam flow pipe 8 into liquid water can be reduced, and the amount of steam injected into the treatment chamber 41 from the nozzle 81 can be increased.
