Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a sterilization and lighting device for a washing machine. Background Art

[0002] Washing machines are indispensable household appliances. When users put clothes into or take clothes out of the drum, especially those using drum washing machines, in low light conditions, they cannot easily see whether the amount of clothes put into the drum is appropriate or whether all the clothes in the drum have been taken out, which affects the user experience. When the washing machine finishes working, water droplets and water stains are inevitably left on the inner wall of the drum. Such a humid environment makes it extremely easy for bacteria to grow in the drum, which can easily cause bacteria to attach to the washed clothes, causing discomfort to the user.

[0003] Since deep ultraviolet LEDs have spectral sterilization properties, are colorless, odorless, and have no byproducts, they are ideal for sterilization needs of household appliances. Therefore, fixing deep ultraviolet LEDs and lighting LEDs on the same light source board can form a device with sterilization and lighting functions. Installing the sterilization and lighting device inside the washing machine allows the sterilization and lighting device to function before, during, and after the washing machine works, ensuring the safety and convenience of the user's laundry process.

[0004] However, if Figure 1 and Figure 2 As shown, the sterilization and lighting device in the prior art includes a deep ultraviolet LED 21, an illumination LED 31 and a light source board 61, wherein the light source board 61 is horizontally mounted on the connector 13 between the laundry compartment door 11 and the inner drum 12 of the washing machine 1, and the deep ultraviolet LED 21 and the illumination LED 31 are mounted side by side on the light source board 61. In the actual use of the washing machine, it is found that the sterilization and lighting device in the prior art has the following problems: since the installation position of the sterilization and lighting device deviates from the center position of the inner drum 12 of the washing machine, and the light source board 61 is horizontally mounted on the connector 13, the deep ultraviolet LED 21 and the illumination LED 31 are both horizontally located inside the inner drum 12. When the deep ultraviolet LED 21 and the illumination LED 31 irradiate the inner drum 12, the irradiation angle range of the deep ultraviolet LED 21 and the illumination LED 31 is prone to positional dead angles, resulting in low light utilization of the deep ultraviolet LED and the illumination LED in the washing machine, and it is impossible to achieve all-round sterilization and illumination of the inner drum.

[0030] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] like Figures 3 to 8As shown, the utility model provides a sterilization and lighting device for a washing machine, wherein the sterilization and lighting device is installed on a connecting piece 13, and the connecting piece 13 is located between the inner drum 12 of the washing machine 1 and the clothing compartment door 11; the sterilization and lighting device comprises a sterilization component 2, a lighting component 3, a shell 4, a U-shaped protective cover 5 and a driving component 6, wherein a through hole 41 is provided at the center of the shell 4, a first limiting plate 42 is connected to the bottom of the outer wall of the shell 4, and the opening end of the U-shaped protective cover 5 is connected to the lower surface of the first limiting plate 42; the driving component 6 comprises a light A source plate 61 and a driving plate 62, wherein the bottom surface of the driving plate 62 is an inclined surface, the bottom surface of the driving plate 62 is connected to the upper surface of the light source plate 61, the sterilization component 2 and the lighting component 3 are both connected to the lower surface of the light source plate 61, the driving plate 62 is located inside the through hole 41, the bottom surface of the outer shell 4 abuts against the upper surface of the light source plate 61, the driving plate 62 is electrically connected to the light source plate 61, the light source plate 61 is electrically connected to the sterilization component 2 and the lighting component 3; the driving plate 62 is electrically connected to the controller of the washing machine 1.

[0032] Specifically, the longitudinal cross-section of the driving board 62 in the present invention is a right-angled trapezoid, wherein the surface where the hypotenuse of the right-angled trapezoid is located is the bottom surface of the driving board 62. The light source board 61 in the present invention adopts a PCB board. The bottom surface of the driving board 62 in the present invention is connected to the upper surface of the light source board 61 by welding.

[0033] In a specific embodiment, the bottom surface of the driving plate 62 is an inclined surface, so that the light source board 61 connected to the bottom surface of the driving plate 62 is inclined in the washing machine 1, and then the lower surface of the light source board 61 is inclined to face the inner drum 12, thereby realizing the adjustment of the irradiation angle range of the sterilization component 2 and the lighting component 3 in the inner drum 12.

[0034] It should be noted that if the washing machine 1 is a drum washing machine, the utility model is installed at the top of the outer side of the connecting member 13, and the lower surface of the light source plate 61 faces the bottom of the inner drum 12 of the washing machine 1; if the washing machine 1 is a pulsator washing machine, the utility model is installed at any position on the outer side of the connecting member 13, ensuring that the lower surface of the light source plate 61 faces the inner drum 12 of the washing machine 1.

[0035] By arranging the sterilization component 2, the lighting component 3 and the driving component 6, and arranging the driving plate 62 whose bottom surface in the driving component 6 is an inclined surface to be connected with the upper surface of the light source plate 61, the light source plate 61 is installed obliquely in the washing machine 1, and then the sterilization component 2 and the lighting component 3 connected to the lower surface of the light source plate 61 are obliquely distributed in the inner drum 12 of the washing machine 1. Compared with the horizontal distribution of the light source plate 61 in the prior art, the utility model realizes the position adjustment of the irradiation angle range of the sterilization component 2 and the lighting component 3 through the obliquely distributed light source plate 61, thereby realizing the sterilization component 2 and the lighting component 3. The lighting component 3 fully covers the bottom of the inner drum 12 of the washing machine 1, thereby improving the utilization rate of light and improving the sterilization and lighting effects; by connecting the light source board 61 and the driving board 62, the light source board 61 and the driving board 62 form a whole and are vertically installed in the washing machine 1. Therefore, when installing the light source board 61 and the driving board 62, only a single space can be set in the washing machine 1, and there is no need to set two spaces required for the light source board 61 and the driving board 62 respectively, which reduces the space occupied by the light source board 61 and the driving board 62 in the washing machine 1 and improves the space utilization rate in the washing machine 1.

[0036] Optionally, a circle of glue storage grooves 43 are provided at the bottom of the outer wall of the shell 4, and the glue storage grooves 43 are located below the first limiting plate 42. A plurality of glue flow holes 44 are provided on the circumference of the glue storage grooves 43, and the plurality of glue flow holes 44 are all connected to the through hole 41; the sterilization and lighting device also includes a sealant 7, and the sealant 7 is filled in the glue storage grooves 43 through the through hole 41 and the plurality of glue flow holes 44 in turn.

[0037] Specifically, the number of the glue flow holes 44 is not limited in the utility model. To ensure the uniformity of the filling of the sealant 7 in the glue storage groove 43, more than two glue flow holes 44 can be opened in the circumference of the glue storage groove 43. The utility model adopts a potting glue with good waterproofness, strong insulation and good weather resistance as the sealant 7, which can enhance the waterproofness and insulation of the utility model. Under the long-term irradiation of the sterilization component 2 and the lighting component 3, the cured sealant 7 does not crack or age, has good weather resistance, and improves the service life of the utility model.

[0038] In a specific implementation, after the staff injects the sealant 7 into the through hole 41, the sealant 7 is filled in the glue storage groove 43 through the glue flow hole 44. After the sealant 7 is cured, the shell 4 and the U-shaped protective cover 5 can be bonded together, thereby ensuring good waterproofness of the utility model.

[0039] Optionally, a circle of grooves is provided on the outer wall of the housing 4 , and the grooves are located below the glue storage grooves 43 , and a sealing rubber ring 8 is installed in the grooves.

[0040] The outer shell 4 and the U-shaped protective cover 5 are sealed by means of sealant 7 and sealing rubber ring 8, so that double sealing, waterproofing and insulation between the outer shell 4 and the U-shaped protective cover 5 can be achieved. The sealing rubber ring 8 is at risk of aging and falling off after long-term use, but under the action of sealant 7, the sealing between the outer shell 4 and the U-shaped protective cover 5 can still be ensured, thereby further improving the waterproof performance and insulation performance of the utility model.

[0041] Optionally, the driving assembly 6 further includes a power supply harness 63 , one end of which is connected to the top surface of the driving plate 62 , and the other end of which is connected to a power cord of the washing machine 1 .

[0042] In a specific embodiment, after the power cord of the washing machine 1 is connected to an external power source, the power supply harness 63 can obtain current through the power cord of the washing machine 1 and supply it to the driving board 62, and then the driving board 62 supplies the light source board 61, so that the sterilization component 2 and the lighting component 3 on the light source board 61 emit light. By sharing a circuit with the washing machine 1, the power supply harness 63 does not need to set up a separate driving circuit for the sterilization component 2 and the lighting component 3, further reducing the space occupied by the driving component 6 in the washing machine 1.

[0043] Furthermore, the light source board 61 in the utility model is divided into a first part and a second part, the first part is electrically connected to the sterilization component 2, and the second part is electrically connected to the lighting component 3. The controller of the washing machine 1 can control the driving board 62 to supply power to the first part and the second part separately, so as to realize the function that the sterilization component 2 and the lighting component 3 can irradiate the inner drum 12 separately as needed. The sterilization component 2 and the lighting component 3 irradiate the inner drum 12 as needed, which can reduce the irradiation time of the sterilization component 2 and the lighting component 3, increase the service life, and reduce the power consumption of the washing machine 1.

[0044] On the basis of the above content, the specific process of the controller of the washing machine 1 driving the sterilization component 2 to irradiate is: when the controller controls the washing machine 1 to run, the inner drum 12 rotates, and while the inner drum 12 rotates, the controller controls the driving board 62 to supply power to the first part of the light source board 61 separately, thereby driving the sterilization component 2 to irradiate the inner drum 12; when the inner drum 12 stops rotating, the controller controls the driving board 62 to stop supplying power to the first part of the light source board 61 separately, thereby stopping the sterilization component 2 from irradiating.

[0045] The specific process of the controller of the washing machine 1 driving the lighting assembly 3 to irradiate is as follows: the utility model also includes a sensor for detecting the switch state of the clothing compartment door 11, the sensor is installed at the connection between the housing of the washing machine 1 and the clothing compartment door 11, and the sensor is electrically connected to the controller of the washing machine 1. The sensor in the utility model can be an infrared sensor, and the infrared sensor has a detection range. When the infrared sensor does not detect the clothing compartment door 11 within the detection range, the infrared sensor transmits a signal to the controller, and the controller determines that the clothing compartment door 11 and the housing are in an open state at this time, and controls the driving board 62 to supply power to the second part of the light source board 61 separately, thereby driving the lighting assembly 3 to irradiate the inner drum 12; when the infrared sensor detects the clothing compartment door 11 within the detection range, the infrared sensor transmits a signal to the controller, and the controller determines that the clothing compartment door 11 and the housing are in a closed state at this time, and controls the driving board 62 to stop supplying power to the second part of the light source board 61, thereby stopping the lighting assembly 3 from irradiating.

[0046] According to the above content, when the user uses the washing machine 1, the irradiation conditions of the sterilization component 2 and the lighting component 3 are specifically as follows: when the user opens the clothing compartment door 11 to put in clothes, the lighting component 3 irradiates; after the user closes the clothing compartment door 11 and starts the washing machine 1 for washing and spinning, the lighting component 3 stops irradiating, and the sterilization component 2 irradiates at the same time, and the irradiation of the sterilization component 2 accompanies the entire washing and spinning process; when the washing and spinning process of the washing machine 1 is completed, the sterilization component 2 stops irradiating; when the user opens the clothing compartment door 11 to take out clothes, the lighting component 3 irradiates; after the user closes the clothing compartment door 11, the lighting component 3 stops irradiating; the user starts the washing machine 1 for sterilization, the sterilization component 2 irradiates, and after the sterilization process of the washing machine 1 stops, the sterilization component 2 stops irradiating.

[0047] Optionally, the sterilization and lighting device also includes a second limit plate 9 and a limit block 10, the lower surface of the second limit plate 9 is connected to the top of the outer shell 4, the through hole 41 extends to the second limit plate 9, and one end of the power supply harness 63 passes through the through hole 41 and is connected to the top surface of the driving plate 62; the limit block 10 is fixed to the lower surface of the second limit plate 9 and is located on one side of the outer wall of the outer shell 4, and the lower surface of the second limit plate 9 and the limit block 10 are both fixed on the connecting member 13.

[0048] In a specific implementation, a connecting hole is provided on the connecting member 13 of the washing machine 1, and a limiting groove is also provided on the inner side of the connecting member 13. The second limiting plate 9 and the limiting block 10 are both passed through the connecting hole and then clamped with the limiting groove through the limiting block 10, thereby realizing the fixation of the utility model on the connecting member 13.

[0049] Optionally, the U-shaped protective cover 5 is made of quartz glass. The U-shaped protective cover 5 made of quartz glass has good high temperature resistance and insulation, and is not easy to crack and age under long-term irradiation of the sterilization component 2 and the lighting component 3; the U-shaped protective cover 5 made of quartz glass also has high permeability, which can improve the irradiation effect of the sterilization component 2 and the lighting component 3.

[0050] Optionally, the angle between the bottom surface of the driving plate 62 and the horizontal plane is in the range of 25°-40°. The angle between the bottom surface of the driving plate 62 and the horizontal plane can be determined according to the size of the inner drum 12 of the washing machine 1. Practice has proved that when the angle between the bottom surface of the driving plate 62 and the horizontal plane is in the range of 25°-40°, the irradiation angle range of the sterilization component 2 and the irradiation angle range of the lighting component 3 are suitable for the inner drum 12 of a common washing machine 1, and can meet the requirements of the common washing machine 1 for sterilization effect and lighting effect, thereby improving the utilization rate of light.

[0051] Optionally, the sterilization component 2 includes a deep ultraviolet LED 21 , and the lighting component 3 includes a lighting LED 31 .

[0052] Optionally, the irradiation angle range of the deep ultraviolet LED 21 is 60°, and the irradiation angle range of the lighting LED 31 is 120°. Figure 3 As shown, the irradiation angle range of the deep ultraviolet LED 21 is 60°, and the irradiation angle range of the lighting LED is 120°. By connecting the deep ultraviolet LED 21 and the lighting LED 31 to the inclined light source plate 61, full coverage of the bottom of the inner drum 12 of the washing machine 1 can be achieved, thereby improving the sterilization and lighting effects.

[0053] It should be noted that different models of the deep ultraviolet LED 21 and the lighting LED 31 can be selected to select different irradiation angle ranges. The specific selection of the deep ultraviolet LED 21 and the lighting LED 31 can be determined according to the size of the inner drum 12 of the washing machine 1.

[0054] In summary, the sterilization and lighting device provided by the utility model adjusts the irradiation angle range of the sterilization component 2 and the lighting component 3 in the washing machine 1 by setting a driving plate 62 with an inclined bottom surface and a light source plate 61 connected to the bottom surface of the driving plate 62, so as to achieve full coverage of the bottom of the inner drum 12 of the washing machine 1 by the sterilization component 2 and the lighting component 3, thereby improving the sterilization effect and the lighting effect; by adopting a sealant 7 and a sealing rubber ring 8 with good waterproofness, strong insulation and good weather resistance, double waterproofing between the outer shell 4 and the U-shaped protective cover 5 is achieved, thereby improving the waterproofness, insulation and weather resistance of the utility model. By integrating the light source plate 61, the driving plate 62 and the power supply harness 63 into one, the overall volume is reduced, and there is no need to set up a driving circuit separately, which reduces the space occupied by the sterilization and lighting device in the washing machine 1.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
