Description

Technical Field

[0001] The utility model belongs to the technical field of dishwasher air ducts, and in particular relates to an air duct structure of a dishwasher. Background Art

[0002] A dishwasher is a household appliance that can automatically clean dishes. Its main functions include washing, disinfecting, drying and storing. It uses high-temperature and high-pressure water and special detergents to efficiently clean dishes. It also has disinfection and drying functions to ensure that the dishes are clean and hygienic. The air duct is the structure of the dishwasher and is responsible for discharging moisture and hot air.

[0003] The existing dishwasher air duct structure adopts a longer rectangular pipe outlet to facilitate the discharge of hot air, and improves the discharge efficiency by increasing the circulation space. However, in the process of discharging hot air, condensation is very likely to produce water droplets. If the water droplets are not cleaned in time, they will gather in one position and easily become moldy. In addition, subsequent cleaning is also very inconvenient. Therefore, it is necessary to provide a dishwasher pipe that can quickly handle condensed water to improve the use effect. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] See also Figure 1-4 As shown, this embodiment is an air duct structure of a dishwasher, comprising:

[0023] The air duct portion includes an air duct pipe body 12;

[0024] The air duct body 12 is used to discharge moisture and hot air inside the dishwasher;

[0025] The air duct part also includes a connecting pipe 11, a threaded ring 13, and a protrusion 14; the threaded ring 13 is threadedly connected to one end of the outer surface of the connecting pipe 11, and the protrusion 14 is equidistantly fixed to the middle of the outer surface of the threaded ring 13;

[0026] The connecting pipe 11 is used in conjunction with the threaded ring 13 to apply a force through the protrusion 14, so that one end of the connecting pipe 11 can be connected to the moisture and hot air outlet of the dishwasher. The protrusion 14 can increase the contact friction force to apply the force required for disassembly and assembly to the threaded ring 13, and the threaded installation method is adopted to meet the tightness and sealing requirements.

[0027] The guide part includes a guide frame 21, a collecting tank 23, a water immersion sensor 24, and an electric heating tube 25; the middle of the bottom end of the guide frame 21 is connected with the collecting tank 23, and the middle of the bottom end of the collecting tank 23 is inlaid with the water immersion sensor 24, and the lower part of the collecting tank 23 is connected with the electric heating tube 25, and the electric heating tube 25 is attached to the bottom end surface of the collecting tank 23;

[0028] The guide frame 21 is the main mounting carrier of the guide part. The collecting tank 23 collects the condensed water formed by the exhaust moisture or hot air, monitors it through the water immersion sensor 24, and operates through the controlled electric heating pipe 25 to generate heat to act on the condensed water, which can quickly dry the condensed water to avoid subsequent cleaning and the formation of surface mildew.

[0029] The middle of the front side of the guide frame 21 is threadedly connected with an isolation grid 22, and the middle of the back side of the guide frame 21 is connected with a connection frame 26;

[0030] The isolation grid 22 can isolate and filter the discharged moisture and hot air, and the connecting frame 26 is used to guide the connection between the frame 21 and the air duct body 12;

[0031] The built-in control end of the water immersion sensor 24 is electrically connected to the input end of the electric heating tube 25;

[0032] Working principle: After applying a tightening force to the threaded ring 13 through the protrusion 14, one end of the connecting pipe 11 is connected to the moisture and hot air outlet of the dishwasher, and the other end of the connecting pipe 11 is connected to the air duct body 12 through the following quick disassembly part, and the air duct body 12 is connected to the connecting frame 26 and extends into the guide frame 21;

[0033] At this time, moisture and hot air are transported to the inside of the guide frame 21 through the connecting pipe 11 and the air duct body 12. The isolation grid 22 on the front of the guide frame 21 can isolate and filter the moisture and hot air, and the water droplets formed by condensation are collected by the collection tank 23. During the collection process, the water immersion sensor 24 detects it and operates through the controlled electric heating pipe 25 to act on the water droplets through the generated heat to quickly dry them.

[0034] This solution can avoid improper cleaning of water droplets, resulting in inconvenience in subsequent cleaning, and improve the use effect.

[0035] See also Figure 1-4 As shown, this embodiment is based on the above embodiment and further includes a quick disassembly portion, which includes a mounting ring 31, a mounting tube 32, a buckle block 33, a first force column 34, and a second force column 35; the buckle block 33 is symmetrically fixedly connected to the opposite side of the outer surface of the mounting tube 32, and the first force column 34 is fixedly connected to the middle part of one side of one buckle block 33, and the second force column 35 is fixedly connected to the middle part of one side of the other buckle block 33, and the upper ends of the first force column 34 and the second force column 35 are cross-movably connected;

[0036] The mounting ring 31 is threadedly fixed to the other end of the connecting tube 11, and the mounting tube 32 is fixed to the mounting ring 31 by buckling the buckle block 33. The cross-movable connection between the upper parts of the first force-applying column 34 and the second force-applying column 35 can be used to quickly disassemble a group of buckle blocks 33 at one time by applying an inward force after applying a force.

[0037] The mounting ring 31 is threadedly connected to the other end of the outer surface of the connecting pipe 11, and the mounting pipe 32 is connected to the middle of the back side of the air duct body 12;

[0038] The installation pipe 32 is connected to the middle part of the air duct pipe body 12 to ensure smooth delivery of moisture and hot air to the inside of the guide frame 21;

[0039] Working principle: When the connecting pipe 11 is connected and installed with the air duct body 12, the mounting ring 31 can be threadedly connected with the other end of the outer surface of the connecting pipe 11 in advance;

[0040] At this time, a set of buckle blocks 33 are aligned with the buckle grooves on the opposite sides of the front of the mounting ring 31, and a force is applied inwardly, and the mounting ring 31 and the mounting tube 32 are fixed by the buckle connection between the buckle blocks 33 and the buckle grooves, and the front of the mounting tube 32 penetrates and connects the air duct body 12, that is, the connecting tube 11 and the air duct body 12 are connected and installed;

[0041] When the two are disassembled, the first force-applying column 34 and the second force-applying column 35 exert an inward force, which acts on a group of buckle blocks 33 and exerts a forward force, so that the mounting tube 32 and the mounting ring 31 can be disassembled at one time;

[0042] This solution can complete the disassembly work quickly and conveniently, improve work efficiency and meet usage requirements.

[0043] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
