Description

Technical Field

[0001] The present invention relates to the technical field of clothing care, and in particular to a steam generating device and a clothing care machine. Background Art

[0002] As people's quality of life continues to improve, clothing care machines are gradually entering people's lives. A clothing care machine is a household appliance that uses steam, vibration, etc. to iron and remove wrinkles on clothes. A steam generator is a component that generates steam. During clothing care, the high-temperature steam generated by the steam generator can be used to iron clothes. Most of the current steam generators use a boiling water method to generate steam, similar to the water tank of an electric water heater in a bathroom. By filling the water tank with water, the heating component in the water tank boils the water, and the water is boiled to generate steam. However, the steam generated by the boiling water method has the following problems: the generated steam is not dry enough, contains a lot of water, and has a low steam pressure, resulting in a poor ironing effect. Summary of the invention

[0003] The problem solved by the present invention is that, in the prior art, the steam generated by the water boiling method is not dry enough, contains a lot of water, has a low steam pressure, and has a poor ironing effect.

[0004] The present invention discloses a steam generating device, comprising:

[0005] A primary heating device, the primary heating device is used to generate primary steam and output it;

[0006] A secondary heating device, the secondary heating device is connected to the primary heating device through a primary pipeline, the secondary heating device is used to receive the primary steam output by the primary heating device, and heat and / or pressurize the primary steam to form secondary pressurized steam for output;

[0007] A three-stage steam spray device is connected to the secondary heating device through a secondary pipeline. The three-stage steam spray device is used to receive the secondary pressurized steam output by the secondary heating device, heat the secondary pressurized steam, and spray the heated steam, and the sprayed steam is used for washing clothes.

[0008] The primary heating device is used to heat water to generate primary steam. The primary steam has a relatively high pressure and is transported to the secondary heating device along the primary pipeline. The steam is heated and / or pressurized in the secondary heating device. On the one hand, the pressure of the steam is increased to compensate for the pressure drop during transportation. On the other hand, the water in the steam is heated to eliminate the moisture and condensed water originally contained in the steam, thereby achieving water-free pressurized output of the steam, significantly reducing the water content of the steam and increasing the pressure of the steam. The secondary heating device heats and / or pressurizes the steam to form secondary pressurized steam. The secondary pressurized steam is transported to the tertiary steam injection device along the secondary pipeline. In the tertiary steam injection device, the steam is further heated, thereby being pressurized and dehydrated and then ejected. The steam ejected after being processed by the above-mentioned secondary heating device and the tertiary steam injection device has sufficient pressure and low water content, thereby significantly improving the ironing effect of clothes. It should be noted that the steam pressure after processing by the three-stage steam spray device is lower than the two-stage booster steam pressure, which is lower than the first-stage steam pressure. This can ensure the steam spray pressure while avoiding steam reflux, thereby ensuring the smooth operation of the steam generating device, significantly improving the ironing effect of clothes, and improving the user experience.

[0009] Furthermore, the primary heating device is provided with at least a water tank and a first heater, the water tank is used to store water, and the first heater is used to heat the water in the water tank to generate steam.

[0010] The first heater is used to boil water and generate primary steam, thereby becoming the steam source of the steam generating device.

[0011] Furthermore, the primary heating device is also provided with a pressure sensor and / or a temperature sensor, the pressure sensor is used to monitor the pressure in the water tank, and the temperature sensor is used to monitor the steam temperature in the water tank.

[0012] According to the pressure sensor, the primary steam pressure in the primary heating device can be accurately grasped, so that when the generated primary steam pressure meets the preset requirements, steam can be supplied to the secondary heating device, thereby ensuring the smooth and continuous operation of the steam generating device. The temperature sensor is used to detect the steam temperature and adjust the corresponding first heater to control the temperature of the output primary steam.

[0013] Furthermore, the secondary heating device is provided with a second heater and / or a pressurizing device, the second heater is used for heating the steam, and the pressurizing device is used for pressurizing the steam.

[0014] When the primary steam is transported to the secondary heating device, its pressure is significantly reduced and its water content is significantly increased. Through the provision of the second heater and / or the booster device, on the one hand, the temperature of the steam is increased to expand its volume and increase its pressure, and on the other hand, the water in the steam is heated to form new steam replenishment, thereby increasing the steam pressure and reducing the water content of the steam, thereby increasing the steam volume, thereby effectively avoiding the formation of watermarks on clothes during ironing and improving the ironing effect.

[0015] Furthermore, the three-stage steam injection device is provided with a third heater, and the third heater is used to heat the steam.

[0016] The setting of the third heater can heat the steam in the three-stage steam injection device, so that the steam can further expand and increase the pressure due to heat, and the water in the steam can be heated to form steam, thereby reducing the water content of the steam while increasing the pressure, to ensure that the steam is injected in the form of high pressure and low water content, which significantly improves the care effect of the clothes.

[0017] Furthermore, a plurality of partitions are alternately arranged in the secondary heating device and / or the tertiary steam injection device, and the partitions are used to divide the internal space of the secondary heating device into a first tortuous flow channel and / or to divide the internal space of the tertiary steam injection device into a second tortuous flow channel.

[0018] This arrangement can significantly increase the flow path and heating area of ​​the steam, thereby extending the time for the steam to be heated and / or pressurized in the secondary heating device and / or the tertiary steam injection device, so that the steam can be fully heated to expand and pressurized, and the water therein can be fully heated to form steam. While increasing the steam pressure and reducing the water content of the steam, the steam volume is also increased, thereby improving the steam conversion efficiency of the steam generating device and improving the washing and care effect of the clothes.

[0019] Furthermore, the partition is a baffle and / or a bump.

[0020] The baffle and / or the protrusion can increase the flow time of the steam in the secondary heating device and / or the tertiary steam spray device and the contact area with the inner wall, thereby increasing the heating time and heating area of ​​the steam, allowing it to fully expand and increase the pressure when heated and eliminate the moisture therein, effectively ensuring the care effect of the clothes.

[0021] Furthermore, at least one steam injection plate is provided on the three-stage steam injection device, and a plurality of steam injection holes are provided on the steam injection plate. The steam injection holes are connected to the second meandering flow channel and are used to inject the steam in the second meandering flow channel.

[0022] The steam spray plate is provided with more than one steam spray hole, and the steam spray hole is connected with the second winding flow channel so as to spray out the steam after heating, pressurization and dehydration, thereby ensuring the temperature, pressure and low water content of the steam, thereby helping to obtain good clothing washing and care effects.

[0023] Furthermore, the steam injection hole is a structure that narrows in the middle.

[0024] This setting can further increase the pressure and speed of steam spraying, thereby ensuring the pressure and temperature during steam ironing and improving the washing and care effects of clothes.

[0025] The present invention also discloses a clothing care machine, comprising the steam generating device as described above.

[0026] The advantages of the clothing care machine and the above-mentioned steam generating device over the prior art are the same, which will not be repeated here.

[0027] Compared with the prior art, the steam generating device and clothing care machine of the present invention have the following advantages:

[0028] The present invention generates steam through a primary heating device, eliminates moisture in the steam and compensates for the steam pressure through a secondary heating device, and finally discharges the steam after three-stage supercharging through a three-stage steam spraying device. On the one hand, the water content of the steam is significantly reduced to avoid watermarks on the clothes during ironing, and on the other hand, the pressure and speed of the steam sprayed from the steam spraying hole are greatly increased, thereby improving the ironing effect on the clothes. The steam generating device provided by the present invention has a simple structure, is easy to use, and significantly improves the care effect of the clothes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] To make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0044] A steam generating device and a clothing care machine according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] This embodiment provides a steam generating device, such as Figure 1-Figure 11 As shown, including:

[0047] A primary heating device 100, the primary heating device 100 is used to generate primary steam and output it;

[0048] A secondary heating device 200, the secondary heating device 200 is connected to the primary heating device 100 through a primary pipeline 400, the secondary heating device 200 is used to receive the primary steam output by the primary heating device 100, and heat and / or pressurize the primary steam to form secondary pressurized steam for output;

[0049] The three-stage steam spray device 300 is connected to the secondary heating device 200 through a secondary pipeline 500. The three-stage steam spray device 300 is used to receive the secondary pressurized steam output by the secondary heating device 200, heat the secondary pressurized steam, and spray the heated steam. The sprayed steam is used for washing clothes.

[0050] In the prior art, the steam generated by the steam generating device in the clothing care machine is directly transported to the steam outlet through a pipeline to care for the clothes to be washed. At this time, the water content of the steam is relatively high, and watermarks are easily produced on the clothes during washing and care, seriously affecting the washing and care effect of the clothes. In addition, the steam pressure will also drop sharply during the transportation process, resulting in insufficient steam pressure at the steam outlet, and poor washing and care effect on the clothes. If the clothing care machine is a cantilever care structure, then in addition to insufficient steam pressure and excessively high water content, a large amount of condensed water will also be produced during the steam transportation process, further affecting the washing and care effect of the clothes. In this example, the primary heating device 100 is used to heat water to generate primary steam. The primary steam has a relatively high pressure and is transported to the secondary heating device 200 along the primary pipeline 400. The steam is heated and / or pressurized in the secondary heating device 200. On the one hand, the pressure of the steam is increased to compensate for the pressure drop during transportation. On the other hand, the water in the steam is heated to eliminate the water and condensed water originally contained in the steam, thereby achieving water-free pressurized output of the steam, significantly reducing the water content of the steam and increasing the pressure of the steam. The secondary heating device 200 heats and / or pressurizes the steam to form secondary pressurized steam. The secondary pressurized steam is transported to the tertiary steam spraying device 300 along the secondary pipeline 500. In the tertiary steam spraying device 300, the steam is further heated and sprayed after being pressurized and dehydrated. The steam sprayed after being processed by the secondary heating device 200 and the tertiary steam spraying device 300 has sufficient pressure and low water content, thereby significantly improving the ironing effect of the clothes. It should be noted that the steam pressure after processing by the three-stage steam spray device is lower than the two-stage booster steam pressure, which is lower than the first-stage steam pressure. This can ensure the steam spray pressure while avoiding steam reflux, thereby ensuring the smooth operation of the steam generating device, significantly improving the ironing effect of clothes, and improving the user experience.

[0051] As one of the optional examples, the primary heating device 100 is provided with at least a water tank 140 and a first heater 110. The water tank 140 is used to store water, and the first heater 110 is used to heat the water in the water tank 140 to generate steam. The water tank 140 may be provided with corresponding devices such as water level detection, water quality cleaning and water replenishment. Since they are not part of the improved content of the present application, they are not limited or elaborated here. The first heater 110 is used to boil water and generate primary steam, thereby becoming the steam source of the steam generating device.

[0052] In this example, the primary heating device 100 is further provided with a pressure sensor 120 and / or a temperature sensor 130, wherein the pressure sensor 120 is used to monitor the pressure in the water tank 140, and the temperature sensor 130 is used to monitor the steam temperature in the water tank 140. The primary steam pressure in the primary heating device 100 can be accurately grasped according to the pressure sensor 120, so that when the generated primary steam pressure meets the preset requirements, steam is supplied to the secondary heating device 200, thereby ensuring the smooth and continuous operation of the steam generating device, and the temperature sensor 130 is used to detect the steam temperature and adjust the corresponding first heater 110, thereby controlling the temperature of the output primary steam.

[0053] As another optional example, the secondary heating device 200 is provided with a second heater 210 and / or a booster 240, wherein the second heater 210 is used to heat steam, and the booster 240 is used to boost the steam. It should be understood that when the primary steam is transported to the secondary heating device 200, its pressure is significantly reduced and its water content is significantly increased. By providing the second heater 210 and / or the booster 240, on the one hand, the temperature of the steam is increased, so that its volume expands and the pressure is increased, and on the other hand, the water in the steam is heated to form new steam supplement, and the water content of the steam is reduced while the steam pressure is increased, and the steam volume is increased, thereby effectively avoiding the formation of watermarks on the clothes during ironing and improving the ironing effect. It should be noted that the booster 240 can be a heating device, or a steam booster in the prior art, or a device that uses turbocharging to boost steam, which is not limited here.

[0054] In this example, the three-stage steam spray device 300 is provided with a third heater 310, and the third heater 310 is used to heat steam. It should be understood that the three-stage steam spray device 300 is used to spray steam to wash and protect clothes. Therefore, the pressure and water content of the steam in the three-stage steam spray device 300 have a great influence on the pressure and water content of the sprayed steam. The third heater 310 can heat the steam in the three-stage steam spray device 300, so that the steam is further heated and expanded and pressurized, and the water in the steam is heated to form steam, thereby reducing the water content of the steam while pressurizing, so as to ensure that the steam is sprayed in the form of high pressure and low water content, which significantly improves the care effect of clothes.

[0055] As one of the preferred examples, a plurality of partitions are staggeredly arranged in the secondary heating device 200 and / or the tertiary steam injection device 300, and the partitions are used to divide the internal space of the secondary heating device 200 into the first winding flow channel 230, and / or, to divide the internal space of the tertiary steam injection device 300 into the second winding flow channel 320. The staggered arrangement means that when the partitions are arranged up and down, the height of the partitions is less than the height of the secondary heating device 200 and / or the tertiary steam injection device 300, and the partitions are staggered and fixedly arranged on the upper and lower inner walls of the secondary heating device 200 and / or the tertiary steam injection device 300, such as Figure 6 As shown, the flow path of the steam is tortuous. When the partition is arranged left and right or front and back, its arrangement is similar to the up and down arrangement, which can be obtained through reasonable inference and will not be limited or elaborated here. This arrangement can significantly increase the flow path and heating area of ​​the steam, thereby extending the time for the steam to be heated and / or pressurized in the secondary heating device 200 and / or the tertiary steam injection device 300, so that the steam is fully heated, expanded and pressurized, and the water (including condensed water) therein is fully heated to form steam. While increasing the steam pressure and reducing the water content of the steam, the steam volume is also increased, thereby improving the steam conversion efficiency of the steam generating device and improving the washing and care effect of the clothes.

[0056] In this example, the partition is a baffle 220 and / or a bump 340. Figure 6-Figure 11 As shown, the baffle 220 and / or the protrusion 340 can increase the flow time of steam in the secondary heating device 200 and / or the tertiary steam spraying device 300 and the contact area with the inner wall, thereby increasing the heating time and heating area of ​​the steam, so that the steam can be fully heated, expanded and pressurized and the moisture therein can be eliminated, effectively ensuring the care effect of the clothes. As one optional example, Figure 6 , Figure 7 As shown, the partition in the secondary heating device 200 is a baffle 220 , and the partition in the tertiary steam injection device 300 is a protrusion 340 .

[0057] As an optional example, at least one steam spray plate 330 is provided on the three-stage steam spray device 300, and a plurality of steam spray holes 331 are provided on the steam spray plate 330, and the steam spray holes 331 are connected with the second winding flow channel 320, so as to spray out the steam in the second winding flow channel 320. In combination with the steam spray plate 330 being provided with more than one steam spray hole 331, the steam spray hole 331 is connected with the second winding flow channel 320, so that the steam after heating, pressurization and dehydration can be sprayed out, thereby ensuring the temperature, pressure and low water content of the steam, thereby helping to obtain a good clothing washing and care effect.

[0058] As a preferred example, the steam injection hole 331 is a structure that is narrowed in the middle.

[0059] The middle narrowing structure means that the apertures of the steam spray hole 331 at the connection points with the second curved flow channel 320 and the steam spray plate 330 are larger than the apertures at the middle section of the steam spray hole 331, or the steam spray hole 331 adopts a structure similar to a venturi tube, which can further increase the pressure and speed of steam spraying, thereby ensuring the pressure and temperature during steam ironing and improving the washing and care effect of clothes.

[0063] It should be understood that the clothing care machine also includes a washing device and / or a drying device, and the details can be referred to the prior art, which will not be limited or elaborated here.
