Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a dishwasher. Background Art

[0002] In current dishwashers, disinfecting the inner cavity of the dishwasher and the tableware on the dish rack mainly relies on an ultraviolet lamp fixedly installed at the upper end of the inner cavity of the dishwasher. Since the position of the ultraviolet lamp is fixed, it cannot completely cover and irradiate every corner of the inner cavity of the dishwasher, which may result in bacteria remaining in some areas of the inner cavity of the dishwasher and on the tableware, thus affecting the disinfection effect of the dishwasher and reducing the user experience.

[0003] In addition, after the ultraviolet lamp works for a long time, the lamp beads will generate heat accumulation due to heat generation. Currently, a common practice is to additionally install a radiator on the ultraviolet lamp to ensure the stable operation of the ultraviolet lamp. However, this will increase the manufacturing cost of the entire dishwasher and also occupy the space of the inner cavity of the dishwasher, making the space of the inner cavity of the dishwasher become compact.

[0038] A dishwasher is an automated kitchen appliance used for cleaning and disinfecting tableware such as bowls, plates, cups, spoons, forks, and knives. Its main purpose is to relieve the burden of hand-washing tableware for people and provide a more hygienic and convenient tableware cleaning device. The working principle of a dishwasher is mainly based on high-pressure jet water flow and special detergents to clean tableware. The dishwasher is connected to the water source of the faucet. When the dishwasher starts working, hot water is sprayed through the spray arm 4 to remove large food residues on the tableware. Then, high-pressure water spraying and special detergents are used to thoroughly clean the tableware. Then, the tableware is rinsed with clean water to remove detergent residues. Then, through the drying module, the tableware is dried using the principle of waste heat, hot air, or condensation.

[0039] There are various types of dishwashers, including but not limited to the following:

[0040] Tabletop dishwasher: Compact, occupies little space, has a relatively small capacity, is flexible to place, and is suitable for kitchens with a small family population or limited space.

[0041] Built-in dishwasher: Has a standardized external dimension, large capacity, and is suitable for families with a large family population or those who need to wash a large number of tableware.

[0042] Integrated sink dishwasher: Integrates the functions of a sink and a dishwasher, is the same size as the sink, combines the functions of a sink and a dishwasher, is more convenient to use, and saves kitchen space at the same time.

[0043] Built-in dishwasher: Needs to be directly embedded in the cabinet, requires the space position of the cabinet to be designed in advance, and water inlets and outlets need to be reserved. It is suitable for families that have completed the decoration and have a large kitchen space.

[0044] Integrated dishwasher: It usually combines the functions of multiple kitchen appliances, such as a disinfection cabinet, a storage cabinet, etc. It has rich functions, saves space, and improves the overall usage efficiency of the kitchen. The type of the dishwasher in the present utility model is not limited.

[0045] Figure 1 It is a structural diagram of a dishwasher body shown according to an exemplary embodiment. As Figure 1 shown, the dishwasher includes a dishwasher inner cavity 5, a spray arm 4, an ultraviolet lamp 7, a turbine 10, tableware, and a brushless motor 12.

[0046] The dishwasher inner cavity 5 is arranged inside the dishwasher. A bowl rack 3 is arranged at the upper end of the dishwasher inner cavity 5. The bowl rack 3 usually has a plurality of adjustable partitions and brackets for placing and storing tableware of different shapes and sizes to be cleaned.

[0047] In a possible implementation manner, a turbine 10 is arranged at the bottom of the dishwasher inner cavity 5. The turbine 10 is a rotary power structure. The turbine 10 is usually composed of a plurality of blades and is used to drive the connected structure to rotate. The present utility model does not limit this. There is a certain angle between the blade and the turbine 10 hub. The present utility model does not limit the angle between the blade and the turbine 10 hub.

[0048] The dishwasher further includes a worm 11. One end of the worm 11 is fixed on the turbine 10, and the other end of the worm 11 is connected to the brushless motor 12. In this way, the turbine 10 can be connected to the brushless motor 12 through the worm 11. Furthermore, when the brushless motor 12 operates, the turbine 10 can be driven to rotate.

[0049] The brushless motor 12 is a driving device that converts electrical energy into mechanical energy. It realizes the commutation of the current through electronic switching devices, such as transistors, so as to drive the motor to rotate. Preferably, the brushless motor 12 in the present utility model is mainly a direct current brushless motor, which mainly consists of a motor main body and a driver and is a mechatronic device. The motor main body includes a permanent magnet rotor, a multi-pole winding stator, a position sensor, etc. The stator winding of the motor usually adopts a three-phase symmetrical star connection, which is similar to a three-phase asynchronous motor. The driver is composed of power electronic devices and integrated circuits, etc. Its functions include controlling the start, stop, braking of the motor, receiving position sensor signals and forward and reverse signals, etc., and controlling the on and off of each power tube of the inverter bridge, so as to control the operation of the motor. Among them, the brushless motor 12 can realize the clockwise rotation and counterclockwise rotation of the turbine 10 by controlling the forward and reverse signals. The present utility model does not limit the rotation direction.

[0050] The brushless motor 12 is connected to the turbine 10 through the worm 11. According to the field-weakening speed-increasing technology, the worm 11 is driven to rotate at a high speed within the turbine 10. Among them, the field-weakening speed-increasing technology is a technology that adjusts the magnetic field strength of the motor, reduces the back electromotive force of the motor, and thereby increases the motor speed. In a permanent magnet brushless DC motor, by utilizing the armature reaction to weaken the magnetic flux of the rotor permanent magnet, the back electromotive force can be reduced, thus realizing the increase in the motor speed.

[0051] After the brushless motor 12 increases its speed through the field-weakening speed-increasing technology, the rotational kinetic energy it generates will be transmitted to the turbine 10 through the worm 11. The worm 11 plays a key transmission role in this process, ensuring the accuracy and stability of power transmission.

[0052] The turbine 10 is arranged on the bottom surface of the inner cavity 5 of the dishwasher, and the spray arm 4 is arranged above the turbine 10. The turbine 10 is driven by the brushless motor 12, thereby driving the spray arm 4 to rotate. As the source of rotational power, the turbine 10 is arranged on the bottom surface of the inner cavity, which can reduce the dissipation and loss of energy, make the power transmission more direct, and can also improve the disinfection efficiency of the dishwasher while ensuring the washing effect of the dishwasher. The spray arm 4 is an important component in the dishwasher for spraying washing water and detergent. Arranging it above the turbine 10 can ensure that the rotational water flow generated by the turbine 10 can directly act on the spray arm 4, thereby driving the spray arm 4 to rotate. The rotation of the spray arm 4 can make it spray a wider and more uniform water flow, covering all corners of the inner cavity 5 of the dishwasher and improving the washing effect.

[0053] Figure 2 It is a structural diagram of a spray arm shown according to an exemplary embodiment. As Figure 2 shown, the top surface of the spray arm 4 can be set as a rounded rectangle, and the present utility model does not limit the shape of the top surface. The spray arm 4 further includes water spray holes 15, which are arranged on both sides of the top surface of the spray arm 4. Among them, the ultraviolet lamp 7 is arranged on one side of the top surface of the spray arm 4, and the water spray holes 15 are arranged on the other side of the top surface of the spray arm 4. Such an arrangement can avoid the water spray holes 15 and prevent the water spray holes 15 from directly spraying water on the ultraviolet lamp 7, thereby causing the service life of the ultraviolet lamp 7 to be too short.

[0054] In the embodiments of this specification, the water spray holes 15 and the ultraviolet lamp 7 are respectively arranged on both sides of the spray arm 4, which can not only realize the cleaning of tableware by the water spray holes 15 but also realize the all-round disinfection of the dishwasher by the ultraviolet lamp 7.

[0055] The ultraviolet lamp 7 is a device capable of emitting ultraviolet rays, with a wavelength range typically between 10 and 400 nm, and is a physical means for sterilization and disinfection. The ultraviolet lamp mainly acts on the deoxyribonucleic acid (DNA) of microorganisms. By destroying the DNA structure, it loses its function of reproduction and self-replication, thereby achieving the purpose of sterilization and disinfection. Ultraviolet sterilization has the advantages of being colorless, odorless, and without chemical residue. For dishwashers of different types and sizes, the lengths and widths of the spray arms 4 provided therein are different. The present utility model does not limit the number of ultraviolet lamps 7 provided on one side of the top surface of the spray arm 4, and it is specifically determined according to the actual situation.

[0056] Figure 3 It is a cross-sectional view of the top surface of a dishwasher shown according to an exemplary embodiment. As Figure 3 shown, the dishwasher further includes a positive conductive coil 14 and a negative conductive coil 13. Among them, the positive conductive coil 14 and the negative conductive coil 13 are both provided at the bottom of the inner cavity 5 of the dishwasher. The positive conductive coil 14 and the negative conductive coil 13 are both circular, and the radius of the positive conductive coil 14 is different from the radius of the negative conductive coil 13. For example, the radius of the positive conductive coil 14 is greater than the radius of the negative conductive coil 13 or the radius of the positive conductive coil 14 is less than the radius of the negative conductive coil 13. The present utility model does not limit the radius relationship between the positive conductive coil 14 and the negative conductive coil 13. The radii of the positive conductive coil 14 and the negative conductive coil 13 are both greater than the radius of the turbine 10. Such a setting enables the turbine 10 not to interfere with the power supply of the ultraviolet lamp 7 by the positive conductive coil 14 and the negative conductive coil 13 when rotating.

[0057] In the embodiments of this specification, the materials of the positive conductive coil 14 and the negative conductive coil 13 can be copper wires. Copper wires are one of the most common materials for conductive coils, and they have excellent wire performance and can withstand high temperatures and pressures; alloy wires are composed of a variety of metals mixed together, and their conductivity is better than that of copper and aluminum, with strong thermal stability and can work under high temperatures and pressures. The present utility model does not limit the materials of the positive conductive coil 14 and the negative conductive coil 13. In the dishwasher, the ultraviolet lamp 7 only requires a 12-volt power supply for power. Therefore, both the positive conductive coil 14 and the negative conductive coil 13 use a 12-volt power supply, and there is no need for a high-power power supply to supply power to the ultraviolet lamp 7. This design improves the working stability and service life of the ultraviolet lamp 7.

[0058] The dishwasher also includes a first metal shrapnel 8 and a second metal shrapnel 9. The metal shrapnels are provided to ensure good contact while the turbine 10 is rotating, and to ensure the stability of the ultraviolet lamp 7 circuit. One end of the first metal shrapnel 8 is in contact connection with the positive conductive coil 14, and the other end of the first metal shrapnel 8 is in contact connection with the ultraviolet lamp 7; one end of the second metal shrapnel 9 is in contact connection with the negative conductive coil 13, and the other end of the second metal shrapnel 9 is in contact connection with the ultraviolet lamp 7. That is, the first metal shrapnel 8 and the second metal shrapnel 9 serve as conductive bridges to connect the conductive coil and the ultraviolet lamp 7. The materials of the first metal shrapnel 8 and the second metal shrapnel 9 are the same. It can be a steel shrapnel, mainly made of carbon steel, and also includes various types of steel shrapnels such as stainless steel and alloy steel. The steel shrapnel has the characteristics of high strength, high hardness, and good toughness; the iron shrapnel, made of pure iron or steel, has the characteristics of low cost and light weight; the aluminum shrapnel has good toughness, corrosion resistance, and electrical conductivity; the stainless steel shrapnel has heat resistance and corrosion resistance. The present invention does not limit the materials of the first metal shrapnel 8 and the second metal shrapnel 9.

[0059] One end of the first metal shrapnel 8 is connected to the positive conductive coil 14, and the other end is in contact connection with the positive electrode of the ultraviolet lamp 7 to ensure that the current flows from the positive conductive coil 14 to the ultraviolet lamp 7; one end of the second metal shrapnel 9 is in contact connection with the negative conductive coil 13, and the other end is in contact connection with the negative electrode of the ultraviolet lamp 7 to ensure that the current flows back from the ultraviolet lamp 7 to the negative electrode, thus forming a complete current loop. Through the above design, a stable power supply for the ultraviolet lamp 7 can be ensured, so as to effectively disinfect the inner cavity 5 of the dishwasher and the tableware; the use of the first metal shrapnel 8 and the second metal shrapnel 9 can also increase the reliability and stability of the ultraviolet circuit connection, and at the same time, this design also makes the maintenance and replacement of the circuit more convenient.

[0060] During the rotation of the spray arm 4, the first metal shrapnel 8 and the second metal shrapnel 9 rotate synchronously. The rotation direction can be clockwise and counterclockwise, and the present invention does not limit this. One end slides flexibly on the positive conductive coil 14 and the negative conductive coil 13 to ensure stable electrical connection; the other end always closely contacts and connects to the positive electrode interface and the negative electrode interface of the ultraviolet lamp 7, so as to continuously provide the required power for the ultraviolet lamp 7 and ensure efficient disinfection treatment of the tableware during the washing process.

[0061] During the operation of the ultraviolet lamp 7, heat is generated. If the generated heat is not dissipated, it will damage the ultraviolet lamp 7 and reduce its service life. Further, the ultraviolet lamp 7 is provided at one end of the top of the spray arm 4. While the spray arm 4 rotates, the internal air flow effectively takes away the heat generated by the ultraviolet lamp 7 beads from within the spray arm 4 and can also be dissipated through the water spray holes 15 of the spray arm 4. There is no need for the dishwasher to provide additional heat dissipation equipment, saving the manufacturing cost of the dishwasher. At the same time, this design not only achieves the heat dissipation effect for the beads of the ultraviolet lamp 7 but also helps to maintain the stable operation of the beads, thereby extending the service life of the beads. The water spray holes 15 of the spray arm 4 also play a role in heat dissipation and ventilation while spraying water for cleaning, ensuring that the ultraviolet lamp 7 beads do not overheat during continuous operation and improving the reliability and safety of the entire system.

[0062] In a possible implementation, the dishwasher further includes an air inlet 6 located at the lower end of one side of the inner cavity 5 of the dishwasher. This design facilitates the dishwasher to enter the storage mode after the washing is completed. Dry air is sucked in through the air inlet 6 and circulated inside the dishwasher to achieve the air drying of the tableware on the dish rack 3 of the dishwasher. The air inlet 6 is mainly connected to the blower system of the dishwasher, and the blower system is connected to the heating module. When the tableware needs to be dried, the blower system is turned on, and at the same time, the air inlet 6 of the dishwasher is opened. Air is sucked in through the air inlet 6 and then heated through the heating module to form hot air in the inner cavity 5 of the dishwasher, drying the tableware and the inner cavity 5 of the dishwasher to keep the inner cavity 5 of the dishwasher and the tableware dry.

[0063] A filter screen can also be provided at the air inlet 6 to prevent impurities such as dust and bacteria outside the dishwasher from entering the inner cavity 5 of the dishwasher, thus causing secondary pollution of the tableware. After the blower system and the heating module complete the drying work, the dishwasher control system will close the air inlet 6 to prevent moist gas or impurities from entering the inner cavity 5 of the dishwasher.

[0064] In a possible implementation, the dishwasher further includes an air outlet 1. The air outlet 1 of the dishwasher can be provided on the side of the inner cavity 5 of the dishwasher, and the position of the air outlet 1 can be higher than the position of the air inlet 6. The air outlet 1 is mainly used to discharge the water vapor and odor in the inner cavity 5 of the dishwasher to keep the ventilation in the inner cavity 5 of the dishwasher normal. During the process of drying the inner cavity 5 of the dishwasher and the tableware using the blower system and the heating module, the air outlet 1 discharges the moist air during the drying process from the dishwasher, thereby achieving the drying of the tableware and the inside of the dishwasher.

[0065] The dishwasher further includes a colony detection sensor 2, which is arranged at the air outlet 1. This location is selected based on the principle of air flow, because the air outlet 1 is the main channel for discharging the internal gas of the dishwasher. After the dishwasher completes the washing and drying tasks, the air in the inner cavity 5 of the dishwasher will be discharged through the air outlet 1. The colony detection sensor 2 may include a sample receiving component for collecting the air discharged from the air outlet 1 of the dishwasher; a light source, which is a key part of the colony detection sensor 2, for irradiating the sample to excite fluorescence or other optical signals; a detector for receiving and measuring the optical signals emitted by the sample; and a signal processing unit for amplifying, filtering, and digitizing the electrical signals output by the detector.

[0066] The dishwasher also includes a control module, and the colony detection sensor transmits the detection result to the control module for analysis and processing. After receiving the detection result of the colony detection sensor 2, the dishwasher control module analyzes the number of colonies. If the control module analyzes that the number of colonies is greater than the preset number, it continues to control the ultraviolet lamp 7 to disinfect the inner cavity 5 of the dishwasher. If the control module analyzes that the number of colonies is less than the preset number, it instructs to disconnect the power supply of the ultraviolet lamp 7, and at the same time, the brushless motor stops running, indicating that the disinfection of the inner cavity 5 of the dishwasher has been completed.

[0067] Regarding the device in the above embodiments, the specific manners in which each module performs operations have been described in detail in the embodiments related to the method, and will not be elaborated here.

[0068] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the utility model disclosed herein. The present invention is intended to cover any variations, uses, or adaptations of the present invention, which follow the general principles of the present invention and include known common knowledge or conventional technical means in the technical field not disclosed by the present invention.

[0069] It should be understood that the present invention is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is only limited by the appended claims.
