Description

Technical Field

[0001] The present invention belongs to the technical field of clothes dryers, and in particular relates to a clothes dryer exhaust gas purification device and a gas clothes dryer. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, various countries have higher and higher requirements for combustion exhaust emissions. As gas dryers are commonly used drying equipment in laundries, the treatment of combustion exhaust gas has attracted more and more attention from users.

[0003] In order to meet the exhaust emission requirements, existing clothes dryers usually improve the combustion efficiency. This method can not only improve the combustion efficiency and reduce the generation of CO and NOX, but also generate more heat through sufficient combustion to improve the drying efficiency.

[0004] For example, a Chinese invention patent with application number CN201410802671.X discloses a gas heating system for a gas clothes dryer. By improving the structure of the gas system, the combustion efficiency in the combustion chamber is improved, the carbon monoxide content in the exhaust gas is reduced, and the ignition success rate is improved. However, the above solution still has the problem of exhaust gas not meeting the standards due to incomplete combustion.

[0005] In this regard, the Chinese invention patent with application number CN201910620356.8 discloses a multifunctional integrated stove, including a stove body bracket, an exhaust air supply device, a smoke collector and de-oiler, an energy-saving burner, an ion purification device, a fin-type heat exchanger and a fresh air curtain. The ion purification device can be used to purify the flue gas generated by combustion. However, the purification device disclosed in the above scheme is integrated on the stove body, which is large in size and complicated to install, and cannot be directly used in a gas dryer.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The object of the present invention is to provide a dryer exhaust gas purification device to address one of the problems in the above-mentioned prior art. By arranging the purification component in the purification channel formed in the shell, a modular setting of the exhaust gas purification device is achieved, and it can be directly connected in series in the exhaust duct of the gas dryer without affecting the size of the dryer and the setting of other structures.

[0008] In order to achieve the above object, the present invention provides a clothes dryer exhaust gas purification device, comprising:

[0009] The shell has a purification channel extending therethrough, and an air inlet and an air outlet connected to the outside are formed on both sides of the shell;

[0010] The purification component is arranged in the purification channel and covers the purification channel, and is used for purifying the gas entering the purification channel.

[0011] In the above scheme, the purification component is arranged in the purification channel inside the shell, ensuring that the overall size of the exhaust gas purification device is moderate, which is convenient for coordination with the air outlet duct of the dryer and will not occupy too much internal space of the dryer, providing favorable conditions for the increase of the drying chamber and also facilitating the miniaturization of the size of the dryer.

[0012] Furthermore, the purification component includes an air guide and noise reduction unit, which is arranged at the air inlet end of the purification channel and is used to control the speed of the airflow entering the purification channel and guide the airflow to be evenly distributed along the radial direction of the purification channel.

[0013] Furthermore, the wind guide and noise reduction unit is in an annular shape as a whole, and the inner edge of the annular shape forms an air guide port for airflow to pass through;

[0014] The wind guiding and noise reduction unit includes a first surface arranged toward the air outlet end of the purification channel. The first surface is annular as a whole and is inclined from the outer edge to the inner edge of the wind guiding and noise reduction unit toward the air inlet end.

[0015] In the above scheme, the wind guide and noise reduction unit is arranged in a ring shape, which can block the airflow about to enter the purification channel, thereby reducing the flow rate of the airflow passing through the guide port, and guiding the airflow entering the purification channel through the first surface, so that the airflow can be evenly distributed on the radial cross-section of the purification channel, forming a laminar airflow flowing along the axial direction, thereby improving the purification effect.

[0016] Furthermore, the wind guiding and noise reduction unit includes a second surface arranged toward the air inlet end of the purification channel, and the second surface is a plane and is arranged in a ring shape as a whole.

[0017] In the above scheme, the second plane surface can better block the airflow in the air outlet duct of the dryer, achieve more precise control of the flow rate of the airflow entering the purification channel, avoid turbulence caused by excessive flow rate, and help improve the purification efficiency.

[0018] Alternatively, as an alternative to the above solution, the second surface is annular as a whole, and is inclined from the outer edge to the inner edge of the wind guiding and noise reduction unit toward the air outlet end.

[0019] In the above alternative solution, since the second surface is set as an inclined surface, it can guide the airflow blown out from the air outlet duct of the dryer. By guiding and reducing the flow rate of the airflow, it avoids directly blocking the airflow and causing the working noise of the exhaust gas purification device to increase, thereby improving the user experience.

[0020] Furthermore, the purification assembly also includes an electric field generator, a catalytic plate and an ultraviolet light generator;

[0021] The electric field generator, the catalytic plate and the ultraviolet light generator are arranged in sequence along the flow direction of the airflow in the remote purification device.

[0022] In the above scheme, the electric field generator can generate a high-voltage electric field, so that the airflow passing through the electric field generator can be ionized and changed into an ionic state, and purified through redox reaction and the strong oxidizing property of O-active groups; at the same time, under the action of the catalytic plate and the ultraviolet light generator, the oxidation reaction is accelerated by breaking the molecular bonds, with higher purification efficiency, so that the high-speed gas can be evenly purified and the volume of unpurified gas can be reduced.

[0023] Furthermore, the air inlet end of the purification channel is contracted to form a limiting rib, and the purification component abuts against the limiting rib when installed in place.

[0024] In the above solution, the positioning of the purification component is achieved by the limiting ribs, and the operator does not need to worry about excessive or insufficient force causing the purification component to fail to be installed in place, thereby simplifying the installation process of the purification component.

[0025] Furthermore, the size of the purification component matches the length of the purification channel, and when the purification component is installed in place, the electric field generator, the catalytic plate and the ultraviolet light generator are abutted in sequence.

[0026] The above scheme further realizes the miniaturization and compact design of the exhaust gas purification device, and improves the space utilization rate of the dryer equipped with the exhaust gas purification device.

[0027] Furthermore, the purification component also includes

[0028] The first filter screen is made of activated carbon fiber and covers the air outlet end of the purification channel.

[0029] Preferably, the purification component further comprises:

[0030] The second filter screen covers the air inlet end of the purification channel.

[0031] In the above scheme, since charged ions can adsorb suspended particles that are dozens of times larger than their own weight, the suspended colloids contained in the gas will clump together and settle under the adsorption of the charged ions; and the first filter is set to ensure that the purified gas is discharged smoothly while blocking the settled colloids, further improving the purification effect and effectively preventing the settled colloids from being discharged to the outside and affecting the environment; the second filter can block the entry of lint, decorations that fall off clothes, etc. at the front side of the purification channel, thereby improving the safety of the exhaust gas purification device. The second aspect of the present invention provides a gas clothes dryer with the exhaust gas purification device described in the above scheme, the housing of the exhaust gas purification device also includes a connecting unit, which is an annular rib formed by folding outwards and arranged at the air inlet end of the purification channel, and the side of the annular rib that is flush with the air inlet end of the purification channel has a protruding annular sealing unit;

[0032] The gas clothes dryer has a drying chamber, which discharges waste gas through an air outlet pipeline. The air inlet end of the purification channel is connected to the air outlet pipeline through a connecting unit, and a sealing connection is achieved through a sealing unit.

[0033] In the above scheme, the exhaust gas purification device can be directly connected to the air outlet pipe of the gas dryer to process the exhaust gas after drying, so as to avoid the impact of CO, NOX and other wastes contained in the exhaust gas on the health of users and the harm to the environment.

[0034] Furthermore, a side of the annular rib that is flush with the air inlet end of the purification channel has a protruding annular sealing unit.

[0035] In the above solution, the annular rib can better improve the sealing effect of the connection.

[0036] The beneficial effects of the present invention are:

[0037] 1. In the clothes dryer exhaust gas purification device provided by the present invention, the flow rate of the airflow entering the purification channel can be effectively reduced by providing an air guide and noise reduction unit, thereby increasing the time the airflow stays in the purification channel and improving the purification effect.

[0038] 2. The first surface is set as an inclined surface, which can guide the airflow entering the purification channel through the guide port, so that the airflow is evenly distributed in the purification channel to form a smooth laminar flow, avoiding the formation of turbulence in the purification channel to affect the purification efficiency, and at the same time reducing the working noise of the exhaust gas purification device and improving the user experience.

[0039] 3. The air inlet end of the purification channel contracts inward to form limiting ribs, which limit the installation of the purification component in place, simplifying the installation process after maintenance and disassembly.

[0040] 4. A connecting unit is also provided at the air inlet end of the purification channel, and a sealing unit is provided on the connecting unit. The sealing unit is used to realize a sealed connection between the purification channel and the air outlet pipeline of the gas dryer, thereby fully preventing the untreated airflow from leaking to the outside.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0049] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0050] The present invention provides a clothes dryer exhaust gas purification device, such as Figures 1 to 5 As shown, including,

[0051] The housing 21 has a purification channel extending therethrough, and an air inlet and an air outlet communicating with the outside are formed on both sides of the housing 21;

[0052] The purification component is arranged in the purification channel and covers the purification channel, and is used for purifying the gas entering the purification channel.

[0053] In the above scheme, the purification component is integrated in the shell 21, so that the exhaust gas purification device 2 can be directly connected in series in the exhaust duct of the dryer. While achieving the purification of the exhaust gas, it will not occupy too much internal space of the dryer, which is conducive to the convenience and miniaturization of the dryer, and is also conducive to the expansion of the dryer, thereby improving the drying efficiency of the dryer.

[0054] The present invention is further described in detail below with reference to specific embodiments.

[0055] Embodiment 1

[0056] As an embodiment of the present invention, this embodiment provides a dryer exhaust gas purification device, wherein the purification component includes an air guide and noise reduction unit 22 arranged in the purification channel. The air guide and noise reduction unit 22 can reduce the speed of the airflow entering the purification channel, and guide the airflow so that the airflow is evenly distributed along the cross-section of the purification channel, thereby improving the exhaust gas purification effect.

[0057] In this embodiment, if Figure 4 As shown, the wind guide and noise reduction unit 22 is arranged at the air inlet end of the purification channel and covers the cross-section of the purification channel, so that the airflow must pass through the wind guide and noise reduction unit 22 to enter the purification channel to ensure the smooth airflow in the purification channel; for this purpose, the shape of the wind guide and noise reduction unit 22 is adapted to the shape of the purification channel.

[0058] It should be noted that the shape of the purification channel can be changed according to actual use requirements. For ease of understanding, this embodiment is described by taking the case where the cross-section of the purification channel is circular as an example.

[0059] The air guiding and noise reduction unit 22 is in the shape of a circular ring as a whole, and its outer diameter matches the cross-sectional size of the purification channel. The inner circumferential surface of the ring forms an air guide port for the airflow to pass through. When the air guiding and noise reduction unit 22 is installed in place, it covers the cross-section of the purification channel, so that all the airflow enters the purification channel through the air guide port of the air guiding and noise reduction unit 22, thereby achieving control of the airflow velocity and ensuring that the airflow entering the purification channel can stay for a sufficient time to achieve sufficient purification.

[0060] Further, such as Figure 4 and Figure 5 As shown, the side of the air guide and noise reduction unit 22 facing the air outlet end of the purification channel is defined as a first surface 221, and the first surface 221 is a non-planar surface, which is inclined from the outer peripheral surface to the inner peripheral surface of the air guide and noise reduction unit 22 in the direction close to the air inlet end, so that the first surface 221 as a whole is in the shape of a gradually opening trumpet mouth, and the airflow can be gradually diffused and filled into the purification channel under the guidance of the first surface 221, and no air vortex will be generated due to a sudden change in diameter, and the airflow entering the purification channel from the guide port has a lower flow rate, and the airflow is more easily guided by the first surface 221 and evenly distributed along the radial direction of the purification channel; at this time, the airflow in the purification channel is in a laminar state, and can smoothly pass through the purification component, thereby ensuring the purification efficiency of the purification component.

[0061] It should be noted here that, in the present embodiment, in the axial cross-section of the air-guiding noise reduction unit 22, the shape corresponding to the first surface 221 is a straight line segment connecting the outer circumference and the inner circumference of the air-guiding noise reduction unit 22; those skilled in the art may also modify the shape of the first surface 221 on the axial cross-section of the air-guiding noise reduction unit 22 to a curved segment with a certain curvature based on their familiarity with the technical principles of the present invention; or in cross-sections corresponding to different diameters, the shape of the cross-section corresponding to the first surface 221 is different, for example, in one of the cross-sections, the shape corresponding to the first surface 221 is a straight line segment, and in other cross-sections, the shape corresponding to the first surface 221 is an arc segment; or in different cross-sections, the shape corresponding to the first surface 221 is an arc segment with different curvatures; conventional improvements to the morphology of the first surface 221 in the air-guiding noise reduction unit 22 also fall within the protection scope of the present invention.

[0062] Furthermore, in order to improve the guiding function of the first surface 221, the first surface 221 is also provided with convex ribs which are radially arranged with the guide port as the center, and the convex ribs assist the airflow to be more evenly distributed in the purification channel.

[0063] Furthermore, the side of the wind guiding and noise reduction unit 22 facing the air inlet end of the purification channel is defined as the second surface 222. In the present embodiment, the second surface 222 is an annular plane, which can better block the airflow and effectively control the speed of the airflow entering the purification channel.

[0064] Further, such as Figure 2As shown, the purification component also includes an electric field generator, a catalytic plate 24 and an ultraviolet light generator. The electric field generator, the catalytic plate 24 and the ultraviolet light generator are arranged in sequence along the air flow direction. The airflow passing through the air guide and noise reduction unit 22 passes through the electric field generator, the catalytic plate 24 and the ultraviolet light generator in sequence to achieve full purification.

[0065] Specifically, the electric field generator includes a plurality of electrode sheets 231 which are parallel to each other and arranged at intervals, and a fixing unit 232 for fixing the electrode sheets 231. The fixing unit 232 is annular and has a certain thickness in a direction perpendicular to the fixing unit 232. The electrode sheet 231 is located in a space defined by the inner circumference of the fixing unit 232 and is connected to the inner circumference to achieve fixation. The outer diameter of the fixing unit 232 matches the cross-sectional size of the purification channel. The catalytic plate 24 is a precious metal honeycomb catalytic plate, and its size matches the cross-sectional size of the purification channel. The ultraviolet light generator includes a fixing frame and an ultraviolet light generating unit 25, and the ultraviolet light generating unit 25 is fixed in the purification channel through the fixing frame. The airflow entering the purification channel through the air guide and noise reduction unit 22 is transformed into an ion state under the influence of the electric field when passing through the electric field generator, and is oxidized by the ultraviolet light irradiation and the catalytic action of the catalytic plate 24 when passing through the catalytic plate 24, so that the combustion exhaust gases such as CO and NOX that are not fully reacted in the airflow are fully purified, and direct discharge will not affect the external environment, thereby improving the environmental protection performance of the gas dryer.

[0066] In the above solution, the fixing frame for fixing the ultraviolet light generating unit 25 can be adjusted according to actual use requirements, without special structural requirements, and can meet the fixing requirements; in this embodiment, the fixing frame is configured as an elliptical ring as a whole.

[0067] Embodiment 2

[0068] As another embodiment of the present invention, this embodiment further makes the following improvements on the basis of the first embodiment.

[0069] In this embodiment, the size of the purification component matches the length of the purification channel, that is, when the purification component is installed in place, the wind guide noise reduction unit 22, the electric field generator, the catalytic plate 24, and the ultraviolet light generator are abutted in sequence, the wind guide noise reduction unit 22 is flush with the air inlet end of the purification channel, and the ultraviolet light generator is flush with the air outlet end of the purification channel, which further reduces the volume of the exhaust gas purification device 2 and improves the compatibility between the exhaust gas purification device 2 and gas dryers with different structures; and the improvement of the compactness of the structure simultaneously shortens the length of the purification channel, and the distance of the airflow through the purification channel is correspondingly shortened, and the probability of turbulence is further reduced, which not only improves the purification efficiency but also reduces the purification noise.

[0070] In addition, the wind guide and noise reduction unit 22 is in contact with the electric field generator, and the airflow enters the electric field generator after being guided by the first surface 221, and is guided by the electrode sheets 231 arranged parallel to each other, thereby further improving the stability of the airflow in the purification channel and improving the purification efficiency.

[0071] Furthermore, in order to facilitate installation and prevent the purification component from protruding from the air inlet end or the air outlet end of the purification channel, a limiting rib 211 is formed at the air inlet end of the purification component by radially contracting inward. The air guide noise reduction unit 22, the electric field generator, the catalytic plate 24, and the ultraviolet light generator are sequentially installed into the air guide channel from the air outlet end of the purification channel. Due to the presence of the limiting rib 211, the user does not need to worry about the problem of installation during installation, which simplifies the difficulty of installation.

[0072] Furthermore, in order to prevent the purification component from falling out of the air outlet end of the purification channel, the surrounding wall of the purification channel close to the air outlet end is slightly contracted, that is, the diameter of the air outlet end of the purification channel is slightly smaller than the diameter of the air inlet end of the purification channel. The contraction of the surrounding wall achieves an interference fit with the purification component, thereby achieving full positioning of the purification component for installation.

[0073] Furthermore, the purification component also includes a first filter 26 made of activated carbon fiber, which covers the air outlet end of the purification channel; since the airflow after being affected by the electric field contains charged ions, the high adsorption capacity can make the suspended colloids in the airflow clump together and settle, thereby realizing the separation of the suspended colloids and the exhaust gas, and the fully purified airflow passes through the first filter 26 and is discharged to the outside, while the settled colloids are blocked by the filter, further avoiding the impact on the external environment.

[0074] Furthermore, the purification component also includes a second filter 27, which covers the air inlet end of the purification channel; it can block impurities mixed in the air flow, such as thread scraps, buttons and decorations that fall off clothes, etc., to ensure the safety of the purification component.

[0075] Embodiment 3

[0076] As another embodiment of the present invention, this embodiment differs from the second embodiment in that the structure of the second surface 222 is different.

[0077] In this embodiment, the second surface 222 is formed by tilting from the outer peripheral surface to the inner peripheral surface of the air guide noise reduction unit 22 toward the direction close to the air outlet end, that is, the second surface 222 forms a trumpet-shaped opening on the side of the air guide noise reduction unit 22 toward the air inlet end of the air guide channel, which can guide the airflow before entering the air guide channel, further improve the air intake efficiency in the air guide channel, and can avoid the formation of vortices on the front side of the air inlet end of the air guide channel to a certain extent, further reducing the working noise of the exhaust gas purification device 2.

[0078] Furthermore, chamfers are provided at the connection points between the first surface 221, the second surface 222 and the inner circumference and the outer circumference of the wind guiding and noise reduction unit 22, so as to facilitate installation by the user without causing damage to the user.

[0079] The present invention also provides a gas-fired clothes dryer having the exhaust gas purification device 2 described in the above embodiment, as follows.

[0080] Embodiment 4

[0081] As another embodiment of the present invention, this embodiment provides a gas-fired clothes dryer having the clothes dryer exhaust gas purification device 2 as described in the second embodiment.

[0082] In this embodiment, the gas clothes dryer has a drying chamber inside, which is connected to the exhaust port 11 of the air outlet pipeline 1 and is connected to the outside of the gas dryer through the air outlet pipeline 1 to discharge the drying air to the outside. Figure 1 As shown, the exhaust gas purification device 2 is connected to the air outlet pipeline 1, that is, the airflow discharged from the air outlet pipeline 1 enters the exhaust gas purification device 2, is fully purified and then discharged, and will not affect the external environment.

[0083] Furthermore, the air outlet end of the purification channel is connected to the air inlet end of the fan 3, and the air outlet end of the fan 3 is connected to the exhaust channel 4, and the exhaust channel 4 extends to the outside of the gas dryer to discharge the drying waste gas.

[0084] Furthermore, in order to improve the connection stability, such as Figure 3 and Figure 5 As shown, a connecting unit 212 is also provided on the shell 21 of the exhaust gas purification device 2. The connecting unit 212 is an annular rib formed by folding outward from the air inlet end of the purification channel. The exhaust gas purification device 2 is connected to the air outlet pipe 1 through the annular rib, which improves the connection stability and facilitates disassembly and assembly.

[0085] Furthermore, the side of the annular rib flush with the air inlet end of the purification channel has an annular sealing unit 214 protruding axially away from the purification channel. The sealing unit 214 is made of elastic material such as rubber. When the exhaust gas purification device 2 is connected to the air outlet pipe 1, the annular rib and the end of the air outlet pipe 1 squeeze the sealing unit 214 from both sides respectively. The sealing unit 214 deforms when under pressure, thereby being able to more stably achieve a sealed connection between the air outlet pipe 1 and the exhaust gas purification device 2.

[0086] Furthermore, a plurality of sealing rings 214 are coaxially arranged on the annular rib, and the height of each sealing ring can be adjusted according to the actual matching conditions, so that when the exhaust gas purification device 2 is connected to the air outlet pipe 1, each sealing ring is squeezed and deformed at the same time; the sealing effect is further improved by arranging multiple sealing rings.

[0087] Furthermore, a wire outlet 213 is provided on the shell 21 of the exhaust gas purification device 2. The position of the wire outlet 213 corresponds to the position when the electric field generating unit 23 is installed in place. It is used for the power supply line and communication line in the purification channel to extend to the outside and be connected to the gas dryer. Since the wire outlet 213 corresponds to the position when the electric field generating unit 23 is installed in place, the electric field generating unit 23 can block the wire outlet 213 to prevent the airflow from leaking from the wire outlet 213 to the outside, thereby solving the power supply and communication problems.

[0088] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
