Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to a dishwasher with a submersible sterilization function. Background Art

[0002] A dishwasher is a household appliance that mainly uses high-pressure cleaning water to clean dirt on dishes or cooking utensils. A dishwasher usually includes a cabinet, a rack and a water spraying mechanism arranged in the cabinet, an inner tank arranged at the bottom of the rack, and a water diversion device for guiding the water in the inner tank to the water spraying mechanism. The operator places pots, bowls or other items to be washed in the rack, and the water in the inner tank water tank is guided to the water spraying mechanism through the water diversion device. The pots, bowls or other items to be washed in the rack are sprayed up and down by the water spraying mechanism to rinse the dirt off the pots, bowls or other items to be washed.

[0003] Dishwashers in the prior art generally have the following problems: 1. In order to make the dishwasher have a sterilization function, an ultraviolet sterilization lamp is usually installed in the cabinet. However, due to the obstruction of tableware, the sterilization range of the ultraviolet sterilization lamp is actually very small. The ultraviolet sterilization lamp can only irradiate a small area around it. In addition, the tableware obstructs each other, making the range even smaller; 2. Usually, the water in the inner tank of the dishwasher will be drained after cleaning. After the actual cleaning is completed, a small amount of residues such as vegetable residues may remain in the inner tank. If the dishwasher is not used for a period of time, the residues in the inner tank may become moldy or form dirt on the inner wall of the inner tank, affecting the subsequent washing effect. Moreover, the water diversion device usually uses a liquid pump. When the liquid pump is unpowered, a space with no air flow will be formed on the other side of the liquid pump, and the residues will also become moldy or form dirt.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention provides a dishwasher with a submersible sterilization function. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Example 1

[0034] like Figures 1 to 5 As shown, this embodiment discloses a dishwasher with a submersible sterilization function, comprising:

[0035] The inner tank 10 is provided with a water storage chamber 11 and a pre-spray chamber 12 located on one side of the water storage chamber 11, and a spraying area 13 is provided above the inner tank 10;

[0036] The water guide module 20 includes a water pump 21 for guiding the water in the water storage chamber 11 to the pre-spray chamber 12;

[0037] The spray module 30 is connected to the pre-spray chamber 12 and sprays water toward the spray area 13;

[0038] The sterilization module 40 includes a sterilization lamp 41 disposed on the inner wall of the water storage chamber 11;

[0039] The purification module 50 includes a first pipe 51 connected to the water storage chamber 11 through a first valve, a second pipe 52 connected to the pre-spray chamber 12 through a second valve, a third pipe 53 connected between the first pipe 51 and the second pipe 52, a fan 54 fixed in the third pipe 53, and an air purifier detachably arranged in the third pipe 53.

[0040] In the dishwasher of this embodiment, the operator can place pots, bowls or other items to be washed in a rack (not shown), and then push the rack into the spray area 13 above the inner tank 10, and guide the water in the water storage chamber 11 to the pre-spray chamber 12 through the water pump 21 of the water guide module 20, and then spray water toward the spray area 13 through the spray module 30, so as to rinse away the dirt on the pots, bowls or other items to be washed.

[0041] A sterilization module 40 is added, and a sterilization lamp 41 is arranged on the inner wall of the water storage chamber 11. The water storage chamber 11 is the place where all water in the dishwasher is collected. The sterilization lamp 41 irradiates the water in the water storage chamber 11, thereby eliminating bacteria, viruses and other microorganisms in the water, thereby achieving a good sterilization and disinfection effect. The sterilized water is then sprayed onto pots, bowls or other items to be cleaned through the spray module 30, so that the sterilization range covers a wider range.

[0042] Moreover, a purification module 50 is also provided. When the water in the inner tank 10 is drained, the first valve and the second valve can be opened, and then the fan 54 can be turned on, so that the gas in the pre-spray chamber 12 passes through the second pipe 52, the third pipe 53, and the water storage chamber 11 in sequence. When the gas passes through the air purifier, it is purified by the air purifier, so that the pre-spray chamber 12 remains clean to prevent the residue from getting moldy or forming dirt; in addition, due to the suction effect of the fan 54, the pressure in the pre-spray chamber 12 is reduced. At this time, the gas in the water storage chamber 11 will pass through the inside of the water pump 21 and enter the pre-spray chamber 12, thereby forming a circulation loop, and at the same time, the gas in the water storage chamber 11 and the pre-spray chamber 12 is purified, and the structure is ingenious.

[0043] It should be noted that the water pump 21 of this embodiment is an impeller driven water pump whose water inlet and water outlet are directly connected to each other by air when not started. Figure 4 As shown, the gap between the impellers of the water pump 21 directly connects the water inlet and the water outlet of the water pump 21 to each other in an air-connected manner.

[0044] As another implementation mode, the water pump 21 of this embodiment can also adopt a centrifugal water pump in which the water inlet end and the water outlet end are gas-connected when the air pressure at both ends is different, such as a centrifugal water pump disclosed in Chinese patent publication number CN111810440B, in which the different air pressures at both ends of the water inlet pipe and the water outlet pipe will drive the arc blades to rotate, thereby connecting the water inlet pipe and the water outlet pipe.

[0045] For further information, please refer to Figure 3 and Figure 4 The germicidal lamp 41 is fixed to the inner tank 10 by screws 42. The inner tank 10 is provided with a mounting hole for the germicidal lamp 41 to penetrate into the inner side of the water storage chamber 11. A sealing ring 43 is also sleeved on the outer side of the germicidal lamp 41. By providing the sealing ring 43, water leakage is avoided and the sealing performance of the inner tank 10 is improved.

[0046] As a preferred embodiment, the germicidal lamp 41 is an ultraviolet lamp. The ultraviolet light emitted by the ultraviolet lamp can destroy the DNA or RNA molecular structure of the microorganism, making it impossible for it to replicate and reproduce normally, and eventually leading to the death of the microorganism. The ultraviolet light in the UVC band can be effectively absorbed by the DNA of the microorganism, causing damage to its genetic material, thereby preventing it from carrying out normal life activities.

[0047] It should be added that the use of ultraviolet lamps in this embodiment is only one of the preferred implementation methods. In other embodiments, the sterilization lamp 41 can also use visible light lamps or infrared lamps. Certain wavelengths of visible light emitted by visible light lamps, such as blue light, have a sterilization effect. Although the infrared light emitted by infrared lamps does not directly kill bacteria, its thermal effect can destroy the cell structure of bacteria and viruses, thereby achieving a disinfection effect.

[0048] Please refer to Figure 1 and Figure 2 A downwardly recessed water collecting plate 14 is fixed at the upper end of the inner tank 10, and a water discharge hole 141 connected to the water storage chamber 11 is provided on the water collecting plate 14. A net bag 15 extending into the water storage chamber 11 is connected to the lower end of the water discharge hole 141, and a filter screen 16 that can be lifted upward is provided in the net bag 15. The filter screen 16 can effectively filter out food residues and grease in the flushing water to prevent these debris from entering the water storage chamber 11 of the inner tank 10; moreover, the filter screen 16 is designed to be a structure that can be lifted upward, which is convenient for operators to clean food residues and grease in the filter screen 16.

[0049] Please refer to Figure 4 Since the net bag 15 and the filter 16 are placed in the middle of the water storage chamber 11, part of the ultraviolet light of the germicidal lamp 41 is blocked, resulting in the opposite side of the germicidal lamp 41 not being irradiated with ultraviolet light. To this end, the present embodiment further provides two reflectors 17 on the inner wall of the water storage chamber 11. The two reflectors 17 are respectively located on both sides of the germicidal lamp 41. Both reflectors 17 form a certain inclination angle with the wall surface for installing the germicidal lamp 41, so that part of the ultraviolet light of the germicidal lamp 41 can be irradiated to the opposite side of the germicidal lamp 41 through the reflectors 17, ensuring that most areas in the water storage chamber 11 can be irradiated with ultraviolet light, thereby improving the sterilization effect.

[0050] Please refer to Figure 2 and Figure 4The water guide module 20 also includes a water inlet pipe 22, a water outlet pipe 23 and a heating mechanism 24. The water storage chamber 11 is connected to the water inlet end of the water pump 21 through the water inlet pipe 22, and the pre-spray chamber 12 is connected to the water outlet end of the water pump 21 through the water outlet pipe 23. The heating mechanism 24 includes an electric heating device 241 fixed to one side of the water pump 21, and a heat pipe 242 connected to the output end of the electric heating device 241. The heat pipe 242 is spirally wrapped around the outer side of the inner pipe of the water outlet end of the water pump 21. The electric heating device can also be turned on during the spraying process. 241, the heat pipe 242 is heated by the electric heating device 241, and then the heat is transferred to the water in the water pump 21 through the heat pipe 242 to form high-temperature water. The high-temperature water can effectively kill bacteria, especially at a high temperature of 70-75°C, it can kill most common bacteria in daily life, and the sterilization rate can reach more than 99%. The effect of this high-temperature disinfection is far better than low-temperature washing or hand washing, especially for dishes that have not been used for a long time, using high-temperature washing can eliminate accumulated bacteria and prevent bacterial reproduction.

[0051] For further information, please refer to Figure 2 The water collecting plate 14 is provided with an air circuit interface 142 connected to the pre-spray chamber 12, the second pipe 52 is connected to the air circuit interface 142, and the first pipe 51 is connected to the water inlet pipe 22. Specifically, the second pipe 52 can be connected to the air circuit interface 142 by threaded connection, which is convenient for disassembly, cleaning or regular maintenance.

[0052] like Figure 5 As shown, the purification module 50 also includes a U-shaped bend pipe 55 connected to one end of the third pipe 53, and a liquid storage tank 56 connected to the upper end of the U-shaped bend pipe 55. The liquid outlet of the liquid storage tank 56 is provided with a third valve. Volatile cleaning liquid can be stored in the liquid storage tank 56 and the U-shaped bend pipe 55. The volatile cleaning liquid can be selected from citric acid and other acidic liquids with good decontamination ability and non-toxic and pollution-free. The operator can fill the liquid storage tank 56 with citric acid in advance, and then control the amount of citric acid flowing out through the third valve so that there is always lemonade at the bending position of the U-shaped bend pipe 55. When the fan 54 is started, the gas in the third pipe 53 will take away part of the volatile citric acid and discharge it from the first pipe 51 into the water storage chamber 11. Citric acid has good degreasing, descaling and deodorizing effects, and can maintain a clean environment in the water storage chamber 11.

[0053] like Figure 5 As shown, the air purifier is a filter cotton 57, which purifies the air. It has a simple structure and low manufacturing cost. In addition, a detachable bottom cover is provided at the bottom of the filter cotton 57, which is convenient for operators to replace the filter cotton 57. Of course, the use of the filter cotton 57 is only a preferred embodiment. In other embodiments, an air purifier such as an activated carbon adsorption device for purifying the air can also be used.

[0054] like Figure 2and Figure 3 As shown, the water collecting plate 14 is provided with a first water spray port 143 and a second water spray port 144 which are connected to the pre-spray chamber 12, and the pre-spray chamber 12 is provided with a flow control device 60 for controlling the water flow of the first water spray port 143 and the second water spray port 144. The flow control device 60 includes a first motor 61 fixed to the bottom of the inner side of the pre-spray chamber 12, and a baffle plate 62 connected to the output shaft of the first motor 61. The baffle plate 62 is provided with through holes corresponding to the positions of the first water spray port 143 and the second water spray port 144. The baffle plate 62 is driven to rotate by the first motor 61, thereby changing the vertical overlapping area of ​​the two through holes with the first water spray port 143 and the second water spray port 144, respectively, to achieve flow control, and the structure is ingenious.

[0055] Please refer to Figure 1 and Figure 2 The spray module 30 includes a lower spray arm 31 connected to the first water spray port 143 and spraying water upward toward the spray area 13, and an upper spray arm 32 connected to the second water spray port 144 and spraying water downward toward the spray area 13. The flushing efficiency is improved by the upper and lower spraying of the lower spray arm 31 and the upper spray arm 32.

[0056] Please refer to Figure 2 and Figure 4 The dishwasher also includes a water supply module and a drainage module 70. The water supply module includes a water inlet interface 81 connected to the water storage chamber 11. The water inlet interface 81 is connected to a faucet through a water pipe and is used to supply water to the water storage chamber 11. The drainage module 70 includes a drainage interface 71 connected to the water storage chamber 11, a stirring blade 72 for guiding the water in the water storage chamber 11 to be discharged from the drainage interface 71, and a second motor 73 for driving the stirring blade 72 to rotate. After rinsing is completed, the second motor 73 can be started, and the stirring blade 72 can be driven to rotate by the second motor 73, so that the water in the water storage chamber 11 is discharged from the drainage interface 71, thereby accelerating the drainage efficiency.

[0057] Example 2

[0058] Compared with Example 1, this embodiment is different in that: Figure 6 As shown, the air purifier uses an electrostatic purification device 58, which can be a plate-type electrostatic purification device. The plate-type electrostatic purification device includes a plurality of cathode plates and anode plates distributed at intervals. After power is applied, an electrostatic field is formed between the cathode plates and the anode plates. The electrostatic field separates the particles in the gas and deposits them on the anode plates, thereby purifying the air.

[0059] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
