Description

Technical Field

[0001] This invention belongs to the technical field of clothing processing equipment, specifically, it relates to a photoplasma generator and clothing processing equipment having the photoplasma generator. Background Technology

[0002] Clothing treatment equipment typically uses ultraviolet light, silver ions, high temperature, and ozone for sterilization. Ultraviolet light can penetrate the air to kill bacteria in clothing, but it can also damage the eyes and skin. Silver ions can inhibit mold growth and deodorize, but if absorbed by internal organs, they may cause illness. High temperature treatment can inactivate bacteria, but clothing made of heat-sensitive materials is prone to deformation. Excessive ozone can strongly irritate the respiratory tract, causing symptoms such as sore throat, chest tightness, and cough.

[0003] Photoplasm is a gas containing ions and free electrons produced by a light tube. Photoplasm and ion clusters decompose oxygen and water molecules into hydroxide ions, free oxygen atoms, superoxide ions, and other oxidants. These molecules are extremely unstable and decompose harmful impurities in the air into inert compounds such as carbon dioxide and water. It destroys organic matter 180 times faster than ultraviolet light and 2000 times faster than ozone.

[0004] For example, a Chinese patent discloses a disinfection and sterilization control device for clothing processing equipment, which uses a plasma generator to intermittently generate plasma; the plasma is heated and decomposed in a closed air chamber by a heater to reduce its ozone concentration before being transported into the ambient space for high-temperature disinfection and sterilization. The air chamber is connected to an inlet valve and an outlet valve. By controlling the opening and closing of the inlet valve and the outlet valve, the air chamber is controlled to open or close. However, the valve structure of the disinfection and sterilization control device is complex and the operation is cumbersome.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a photoplasma generating device to achieve the purpose of simplifying the use of components and reducing production costs.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A photoplasma generator, comprising:

[0009] An outer casing, wherein an air chamber is formed within the outer casing;

[0010] Photoplasma tubes are used to irradiate the gas inside a gas chamber;

[0011] A connecting pipe, wherein the air inlet of the connecting pipe is connected to the air outlet of the air chamber;

[0012] A sealing element is used to control the connection or disconnection between the connecting pipeline and the air chamber. The sealing element can reciprocate along the inside of the connecting pipeline.

[0013] Furthermore, the connecting pipeline includes at least an inclined pipeline section extending upward along the gas flow direction, and a sealing element is provided in the inclined pipeline section;

[0014] The air chamber is equipped with a fan for discharging the gas inside the air chamber into the connecting pipe. The gas flows through the inclined pipe section, causing the sealing element to move upward, so that the connecting pipe is connected to the air chamber.

[0015] Furthermore, a limiting stop is provided on the inner peripheral wall of the inclined pipe section, extending radially into the interior of the inclined pipe section. When the gas flows through the inclined pipe section, it drives the sealing element to move upward and fit against the limiting stop, so that the sealing element stops moving upward.

[0016] Preferably, a limiting stop is provided on the inner peripheral wall of the inclined pipe section, extending radially into the interior of the inclined pipe section, and the limiting stop is in contact with the sealing component.

[0017] Furthermore, the inner diameter of the inclined pipe section gradually increases along the gas flow direction;

[0018] Preferably, the inclined pipe section is a frustum-shaped pipe that extends upwards at an incline.

[0019] Furthermore, a portion of the outer shell is recessed into the air chamber to form a receiving cavity that opens in the horizontal direction. The receiving cavity is provided with an elastic element that is interference-fitted with the receiving cavity, and the elastic element has a plug hole.

[0020] Furthermore, a photocatalytic excitation layer is provided inside the outer shell, and the photoplasma tube is arranged opposite to the photocatalytic excitation layer, or the photoplasma tube is provided with a photocatalytic excitation layer.

[0021] Furthermore, the photoplasma tube is an ultraviolet light tube;

[0022] Preferably, the ultraviolet light tube is a wide-band ultraviolet light tube;

[0023] More preferably, the ultraviolet light tube has UVC and / or UVD ultraviolet bands.

[0024] The present invention also provides a garment processing device to improve the sterilization and deodorization efficiency of garment processing devices.

[0025] A garment processing device, comprising:

[0026] The box contains a clothing processing tube.

[0027] As described in any of the above-mentioned photoplasma generating devices, the air outlet end of the connecting pipe is connected to the inside of the clothing treatment drum via the air outlet pipe.

[0028] Furthermore, it also includes a crossbeam located on the top of the housing and a mounting bracket fixedly connected to the crossbeam, wherein the outer shell is detachably and fixedly connected to the mounting bracket via a plug-in structure;

[0029] Preferably, the crossbeam and the mounting bracket are respectively provided with connection holes, and fasteners pass through the connection holes on the crossbeam and the mounting bracket in sequence to fasten the crossbeam and the mounting bracket together.

[0030] Furthermore, a portion of the outer shell is recessed into the air chamber to form a receiving cavity that is interference-fitted with the elastic element. The elastic element has a insertion hole, and the mounting bracket has barbs that are inserted into the insertion hole.

[0031] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0032] 1. In this invention, photoplasma irradiates the air in the gas chamber to form a sterilizing gas. The sealing component opens the connecting pipe under the action of the sterilizing gas, realizing the connection between the connecting pipe and the gas chamber. This allows the photoplasma generator to input sterilizing gas into the clothing treatment equipment, thereby achieving sterilization and deodorization of the clothing. The sealing component has a simple structure and is easy to operate, allowing the sterilizing gas to be quickly discharged without the need for valve components, thus reducing production costs.

[0033] 2. In this invention, the photoplasma generator has a photocatalytic excitation layer. Under the catalysis of specific nanoscale noble metal media, the broadband ultraviolet light tube irradiates the air, which can generate a large number of hydrogen oxygen ions, super oxygen ions, hydrogen peroxide and pure negative oxygen ions, thereby improving the sterilization effect.

[0034] 3. In this invention, the gas in the air chamber is irradiated by a photo-plasma tube to form a bactericidal gas, which is then blown into the clothing treatment drum through the air outlet duct. This not only sterilizes the inside of the clothing treatment drum but also sterilizes the clothes inside the drum, and has a particularly good sterilization effect on clothes that cannot withstand high temperatures.

[0050] Example 1

[0051] like Figures 1 to 7 As shown, this embodiment of the invention provides a photoplasma generator 3, comprising: a housing 31, wherein a gas chamber 32 is formed within the housing 31; a photoplasma tube 34 for irradiating the gas in the gas chamber 32; a connecting pipe 38, wherein the air inlet of the connecting pipe 38 is connected to the air outlet 36 of the gas chamber 32; and a sealing member 37 for controlling the connection or disconnection between the connecting pipe 38 and the gas chamber 32, wherein the sealing member 37 can reciprocate along the interior of the connecting pipe 38.

[0052] In this embodiment, under the action of airflow, the sealing component 37 can reciprocate along the inside of the connecting pipe 38 to realize the connection or disconnection between the connecting pipe 38 and the air chamber 32. The sealing component 37 has a simple structure and is easy to operate, which reduces the amount of parts used and lowers the production cost.

[0053] In this embodiment, the photoplasma tube 34 irradiates the gas in the gas chamber 32, thereby completely killing the microorganisms carried in the gas in the gas chamber 32. The photoplasma tube 34 can emit photoplasma and ion clusters, which decompose the oxygen and water molecules in the gas in the gas chamber 32 into hydroxide ions, free oxygen atoms, superoxide ions and other oxidants, and decompose the odor substances carried in the gas in the gas chamber 32 into inert compounds such as carbon dioxide and water.

[0054] In this embodiment, the gas in the gas chamber 32 after being irradiated by the photo-plasma tube 34 forms a bactericidal gas and is introduced into the clothing treatment drum 2. This not only sterilizes the inside of the clothing treatment drum 2, but also sterilizes the clothes in the clothing treatment drum 2. It has a particularly good sterilization effect on clothes that cannot withstand high temperatures. At the same time, the odor of the clothes is quickly and easily removed.

[0055] like Figure 6 and Figure 7 As shown, in this embodiment, the connecting pipe 38 includes at least an inclined pipe section 381 extending upward along the gas flow direction. The inclined pipe section 381 is provided with a sealing member 37, which can move upward under the action of airflow to connect the connecting pipe 38 and the air chamber 32, or move downward under the action of gravity to disconnect the connecting pipe 38 and the air chamber 32.

[0056] like Figure 6 and Figure 7 As shown, in this embodiment, a fan 33 is provided in the air chamber 32 to discharge the gas in the air chamber 32 into the connecting pipe 38. The gas flows through the inclined pipe section 381 and drives the sealing member 37 to move upward, so that the connecting pipe 38 is connected to the air chamber 32. There is no need for valve assembly to control the opening and closing of the connecting pipe 38, making the operation more precise and simple.

[0057] like Figure 6 and Figure 7 As shown, in this embodiment, a limiting stop 382 extending radially into the interior of the inclined pipe section 381 is provided on the inner peripheral wall of the inclined pipe section 381. When the gas flows through the inclined pipe section 381, it drives the sealing member 37 to move upward and fit against the limiting stop 382, ​​so that the sealing member 37 stops moving upward.

[0058] Preferably, a limiting stop 382 is provided on the inner peripheral wall of the inclined pipe section 381, extending radially into the interior of the inclined pipe section 381. The limiting stop 382 is in contact with the sealing member 37, so that the sealing member 37 moves upward under the action of airflow until it is in contact with the limiting stop 382, ​​at which point the sealing member 37 stops moving upward, and the bactericidal gas is discharged from the gap between the sealing member 37 and the connecting pipe 38.

[0059] like Figure 6 and Figure 7 As shown, in this embodiment, the inner diameter of the inclined pipe section 381 gradually increases along the gas flow direction, and the bactericidal gas formed by the gas in the gas chamber 32 after being irradiated by the photoplasma tube 34 can flow out more smoothly through the gap between the sealing member 37 and the connecting pipe 38.

[0060] Preferably, the inclined pipe section 381 is an upwardly inclined frustum-shaped pipe, which facilitates the discharge of sterilizing gas through the connecting pipe 38, thereby sterilizing and deodorizing the inside of the garment processing equipment.

[0061] like Figure 3 As shown, a portion of the outer shell 31 is recessed into the air chamber 32 to form a receiving cavity 312 that opens in the horizontal direction. An elastic element 8 is provided in the receiving cavity 312 and is interference-fitted with the receiving cavity 312. An insertion hole is provided on the elastic element 8. The receiving cavity 312 forms a mounting groove for installing the elastic element 8. The material of the elastic element can be rubber, silicone or other elastic materials.

[0062] like Figure 6 and Figure 7 As shown, in this embodiment, the sealing component 37 can be a spherical ball, and the material of the ball can be rubber, silicone, plastic, metal, etc.

[0063] The photoplasma generator 3 irradiates the air in the gas chamber 32 to form a sterilizing gas. The sterilizing gas drives the sealing component 37 to open the connecting pipe 38, so that the connecting pipe 38 is connected to the gas chamber 32. This allows the photoplasma generator 3 to input sterilizing gas into the clothing treatment equipment, thereby sterilizing and deodorizing the clothing. The sealing component 37 has a simple structure and is easy to operate, which reduces the number of parts used and lowers the production cost.

[0064] Example 2

[0065] This embodiment is a further limitation of the first embodiment described above. The outer shell 31 is provided with a photocatalytic excitation layer, and the photoplasma tube 34 is disposed opposite to the photocatalytic excitation layer, or the photoplasma tube 34 is provided with a photocatalytic excitation layer.

[0066] In this embodiment, a photocatalytic excitation layer is provided inside the air chamber 32, and a photocatalytic plasma tube 34 is disposed on one side of the photocatalytic excitation layer, or the photocatalytic plasma tube 34 has a photocatalytic excitation layer inside. The photocatalytic excitation layer is composed of nanoscale noble metal catalytic materials. Under the catalysis of specific nanoscale multiple noble metal media, the photocatalytic plasma tube 34 irradiates the air inside the air chamber 32, generating a large number of hydrogen ions, superoxide ions, hydrogen peroxide and pure negative oxygen ions, forming photohydrogen ions, which can quickly and effectively kill more than 99% of bacteria, viruses and molds in the air, and eliminate odors in the air, thereby achieving the effect of purifying the air.

[0067] like Figure 6 and Figure 7As shown, in this embodiment, the photoplasma tube 34 is an ultraviolet light tube. Ultraviolet light can be divided into vacuum ultraviolet light (ultra-low frequency, UVD), short-wave sterilization ultraviolet light (low frequency, UVC), medium-wave erythema effect ultraviolet light (medium frequency, UVB), and long-wave black spot effect ultraviolet light (high frequency, UVA) according to its wavelength.

[0068] Preferably, the ultraviolet light tube is a wide-band ultraviolet light tube. The wide-band photon tube can be a broadband ultraviolet light tube. Compared with ultraviolet light tubes with UVC and / or UVD ultraviolet bands, when irradiating the air, the broadband ultraviolet light tube can generate a large number of hydroxyl ions, superoxide ions, hydrogen peroxide and pure negative oxygen ions under the catalysis of specific nanoscale multi-precious metal media, thereby improving the sterilization effect.

[0069] More preferably, the ultraviolet tube has UVC and / or UVD ultraviolet bands. The UVC band of ultraviolet light has a wavelength of 200-275nm, while the 253.7nm UVC band ultraviolet light has a highly efficient bactericidal effect; the UVD band of ultraviolet light has a wavelength of 100-200nm, while the 185nm UVD ultraviolet light can excite oxygen and water in the air to produce photoplasma clusters.

[0070] In this embodiment, a photoplasma concentration detection device is provided in the air chamber 32 or the clothing treatment tube 2. The photoplasma concentration detection device is used to detect whether the photoplasma concentration in the air chamber 32 or the photoplasma concentration inside the clothing treatment tube 2 through which sterilizing gas is introduced meets the sterilization requirements. The photoplasma concentration detection device is a concentration sensor.

[0071] In this embodiment, the clothing processing drum 2 is equipped with an odor detection device. The odor detection device is used to detect the odor concentration and taste concentration of the clothing processing drum 2 or the clothing inside it, so as to accurately control the operation of the photoplasma generator 3.

[0072] The aforementioned photoplasma generator 3 has a photocatalytic excitation layer. Under the catalysis of specific nanoscale noble metal media, the broadband ultraviolet light tube irradiates the air, which can generate a large number of hydrogen oxygen ions, super oxygen ions, hydrogen peroxide and pure negative oxygen ions, thereby improving the sterilization effect.

[0079] In this embodiment, an air inlet valve is provided on the air inlet pipe to control the opening and closing of the air outlet pipe 4, thereby controlling the connection or disconnection between the air chamber 32 and the air inlet pipe, so as to introduce the gas inside the clothing processing drum 2 into the air chamber 32 according to the usage of the clothing processing equipment or the actual usage needs of the user.

[0080] like Figures 1 to 5 As shown, in this embodiment, the air inlet of the air outlet duct 4 is connected to the air chamber 32 via the connecting pipe 38. A door seal 7 is provided between the shell and the front flange of the clothing processing cylinder 2. The air outlet of the air outlet duct 4 is connected to the upper front side of the clothing processing cylinder 2 or the door seal 7, so that the circulating airflow irradiated by the photo-plasma tube 34 in the air chamber 32 is blown into the interior of the clothing processing cylinder 2 through the air inlet duct.

[0081] like Figure 1 and Figure 2 As shown, in this embodiment, the air inlet of the air outlet duct 4 is connected to the photo-plasma generator 3, and the air outlet of the air outlet duct 4 is connected to the upper front side of the clothing treatment drum 2.

[0082] like Figure 1 and Figure 2As shown, in this embodiment, the air inlet of the air outlet duct 4 is connected to the photo-plasma generator 3, and the air outlet of the air outlet duct 4 is connected to the door seal 7. The sterilizing gas emitted by the photo-plasma generator 3 is blown into the air outlet duct 4 and then flows into the interior of the clothing treatment drum 2 through the door seal 7.

[0083] In this embodiment, the radial dimension of the air inlet duct is larger than that of the air outlet duct 4, which is conducive to the rapid flow of circulating air. This allows the airflow in the air inlet duct to be quickly introduced into the air chamber 32, and the photoplasma generator 3 is used to sterilize and deodorize the airflow originating from the inside of the clothing treatment drum 2.

[0084] like Figures 1 to 5 As shown, in this embodiment, the connecting pipe 38 and the air outlet pipe 4 are fixedly connected by buckles, clamps, etc., making disassembly and assembly more convenient.

The elastic member 8 is provided with a insertion hole, and the mounting bracket 6 is provided with barbs 61 that are inserted into the insertion hole.

[0088] In this embodiment, compared to the photoplasma generator 3 being directly connected to the mounting bracket 6, the mounting bracket 6 and the elastic element 8 are fixedly connected via a plug-in structure. The elastic element 8 has a certain buffering effect, reducing the damage to the photoplasma tube 34 caused by the vibration of the clothing processing equipment.

[0089] like Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, the outer shell 31 is recessed inward to form a terminal slot 311 for installing terminal blocks. The terminal blocks are connected to the controller of the garment processing equipment to activate the photoplasma tube 34 to irradiate the gas in the gas chamber 32.
