[0034] like Figure 1 , Figure 2 As shown, an embodiment of the utility model provides a photoplasma air duct assembly, including an air duct 1 and a photoplasma generator 2. An air inlet 11 and an air outlet 12 are respectively provided at both ends of the air duct 1, and two opposite side walls of the air duct 1 are respectively a first side wall 13 and a second side wall 14. The air outlet 12 is provided on the first side wall 13, and the photoplasma generator 2 is provided on the inner wall of the second side wall 14, and the photoplasma generator 2 is arranged opposite to the air outlet 12. A photoplasma voltage plate 3 is fixedly provided on the air duct 1, and the photoplasma voltage plate 3 is electrically connected to the wire of the photoplasma generator 2, and is used to supply power to and control the photoplasma generator 2.
[0035] The photo plasma air duct assembly provided in the embodiment of the utility model can be installed on the outside of the inner tank of the dishwasher, and the air outlet 12 is connected to the air inlet of the inner tank of the dishwasher. When air enters the inner tank through the air duct 1, the photo plasma generator 2 at the air outlet 12 works, and generates photo plasma groups through the action of light energy. The wind transported by the air duct 1 causes the photo plasma separated in the air to flow to every corner of the inner tank cavity, truly achieving no dead angle coverage, disinfecting bacteria in the inner tank cavity, and removing odors in the inner tank cavity. Compared with the technical solution of arranging the photo plasma generator assembly in the inner tank in the prior art, the present utility model arranges the photo plasma generator 2 in the air duct 1 outside the inner tank, which can prevent the photo plasma generator 2 from directly touching the tableware or bowl basket and damaging the photo plasma generator 2. In addition, the photo plasma generator 2 is installed in the air duct 1 outside the inner tank, which is not easily invaded by water vapor, causing the photo plasma generator 2 to be damaged by water vapor erosion. The light plasma air duct assembly provided in the embodiment of the utility model eliminates the risk of the light plasma generator 2 being smashed with tableware and bowl baskets, as well as the risk of being attacked by water vapor, which can make the light plasma generator 2 safer and more reliable, thereby greatly improving the reliability and stability of the product. In this embodiment, the light plasma voltage plate 3 and the light plasma generator 2 are packaged separately, which can avoid component failure and damage caused by sealing defects. In addition, the light plasma voltage plate 3 is not only installed on the outside of the inner tank, but also installed on the outside of the air duct 1 outside the inner tank. Compared with the small amount of water vapor in the air duct 1, there is no water vapor attack on the outside of the air duct 1, which can achieve the effect of isolating the light plasma voltage plate 3 from water vapor. Therefore, this embodiment eliminates the risk of the light plasma generator 2 and the light plasma voltage plate 3 being smashed with tableware and bowl baskets, as well as the risk of being attacked by water vapor, which can make the light plasma generator 2 and the light plasma voltage plate 3 safer and more reliable, thereby greatly improving the reliability and stability of the product.
[0036] like Figure 2 , Figure 3 , Figure 4 As shown, in one embodiment of the present invention, the second side wall 14 is provided with a lead hole 15 corresponding to the light plasma generator 2, and the wire of the light plasma generator 2 is passed through the lead hole 15. Figure 2 , Figure 4 As shown, the outer periphery of the lead hole 15 is provided with a first groove 16, and the outer side of the second side wall 14 is provided with a second groove 17 connected to the first groove 16. The wire of the photoplasma generator 2 is arranged in the second groove 17 and connected to the photoplasma voltage board 3, so as to facilitate wiring and protect the wire of the photoplasma generator 2. In this embodiment, the first groove 16 is circular, and the second groove 17 is long and extends in the direction of the photoplasma voltage board 3. In order to improve the sealing performance of the air duct 1, a sealing ring 21 is provided between the photoplasma generator 2 and the lead hole 15. Figure 5As shown, the sealing ring 21 can be integrally formed with the photoplasma generator 2 .
[0037] like Figure 1 , Figure 2 As shown, in one embodiment of the utility model, the air duct 1 is U-shaped, including a first section 101, a second section 102 and a third section 103 connected in sequence. The air inlet 11 is located at one end of the third section 103 away from the second section 102, and the air outlet 12 is located at one end of the first section 101 away from the second section 102. The photo plasma voltage board 3 is located between the first section 101 and the third section 103, and the photo plasma voltage board 3 is covered by the air duct 1 to protect the photo plasma voltage board 3 and prevent it from colliding with other components and causing damage.
[0038] In order to facilitate the installation of the photo plasma voltage plate 3 between the first section 101 and the third section 103, as shown in FIG. Figure 3 , Figure 4 , Figure 6 As shown, the surfaces opposite to the first section 101 and the third section 103 are both provided with guide posts 18, and the light plasma voltage board 3 is provided with slide grooves 31 corresponding to the guide posts 18. During installation, the slide grooves 31 of the light plasma voltage board 3 are aligned with the guide posts 18 and slid along the guide posts 18 into between the first section 101 and the third section 103, which has fast installation speed, accurate installation position and high installation efficiency.
[0039] In order to further improve the accuracy of the installation position of the optical plasma voltage plate 3, as Figure 1 , Figure 3 , Figure 4 As shown, a limit baffle 181 is provided at the end of the guide column 18. When the photo plasma voltage board 3 abuts against the limit baffle 181, it is installed in place. The limit baffle 181 can also prevent the slide groove 31 of the photo plasma voltage board 3 from sliding too far and causing it to separate from the guide column 18.
[0040] When the photo plasma voltage board 3 is located at the predetermined installation position, in order to prevent the photo plasma voltage board 3 from sliding out from the reverse direction and detaching from the guide column 18, a positioning structure is provided in this embodiment. Figure 6 As shown, the two ends of the slide slot 31 are respectively a first end 311 and a second end 312. The first end 311 is open and corresponds to the limit baffle 181. The opening of the first end 311 is used to slide into the guide column 18. The second end 312 is provided with a blocking plate 32 and is closed. Figure 2-Figure 4As shown, the surfaces opposite to the first section 101 and the third section 103 of the air duct 1 are provided with undercuts 19 corresponding to the second end 312 of the slide groove 31. The outer side of the blocking plate 32 is used for the undercuts 19 to be snapped in place. During installation, when the first end 311 of the photo plasma voltage board 3 passes through the undercuts 19 and the guide column 18 in sequence and slides in and approaches the predetermined installation position, the outer side of the undercuts 19 contacts the inner side of the blocking plate 32, and a force is applied to make the photo plasma voltage board 3 continue to slide in the direction of the limit baffle 181 and abut against the limit baffle 181. At this time, the undercuts 19 pass over the blocking plate 32 and abut against the outer side of the blocking plate 32, thereby limiting the photo plasma voltage board 3 from sliding loose in the direction away from the limit baffle 181.
[0041] like Figure 6 As shown, in order to facilitate the undercut 19 to pass over the blocking plate 32, a first guiding slope 321 is provided on the inner side of the blocking plate 32, and the height of the first guiding slope 321 gradually increases along the direction from the first end 311 to the second end 312 (i.e., the direction away from the limit baffle 181). Figure 4 As shown, the outer side of the undercut 19 is provided with a second guiding inclined surface 191 corresponding to the first guiding inclined surface 321. The inner side of the undercut 19 abuts against the outer side of the blocking plate 32 of the chute 31, and preferably, the inner side of the undercut 19 is a vertical surface.
[0042] like Figure 6 As shown, in order to reduce the resistance when the light plasma voltage board 3 slides into the first section 101 and the third section 103, the light plasma voltage board 3 is provided with a ridge 33, and the slide groove 31 is arranged in the ridge 33. Gaps are formed on both sides of the ridge 33, and no contact is made with the surface of the first section 101 and the third section 103, thereby avoiding friction caused by the uneven surface of the light plasma voltage board 3 or the air duct 1. In addition, a threading hole 35 for threading is also provided on the housing 34 of the light plasma voltage board 3.
[0043] like Figure 7 As shown, in one embodiment of the present invention, the air outlet 12 is provided with a cover plate 121, and the cover plate 121 is provided with a guide hole 122 for controlling the air outlet direction of the air outlet 12. Figure 8 As shown, a plurality of baffles 123 may be provided in the air duct 1 to reduce the flow rate of air in the air duct 1 and make the distribution of the photoplasma in the inner tank of the dishwasher more uniform.
[0044] The utility model also provides a dishwasher, comprising the above-mentioned light plasma air duct assembly. The dishwasher is provided with an inner tank, the inner tank is provided with an air inlet, and the air outlet of the light plasma air duct assembly is connected to the air inlet to flow the light plasma to every corner of the inner tank cavity, disinfect bacteria in the inner tank cavity, and remove odor in the inner tank cavity.
[0045] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
