Technical Field
[0001] This utility model belongs to the field of dishwasher technology, specifically relating to a dishwasher filter device. Background Technology
[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for home use and mainly include cabinet-style, countertop-style, sink-integrated, and combined models. Commercial dishwashers can be classified into five main categories according to their structure: cabinet-style, hood-style, basket-type, belt-type, and ultrasonic. They reduce the labor intensity of kitchen staff in restaurants, hotels, and government canteens, improve work efficiency, and enhance hygiene.
[0003] Existing dishwasher filter devices typically have only one filter, which can only filter large particles of residue and cannot filter finer debris. The filter is inconvenient to remove during use, making it difficult to clean, which can easily breed bacteria, produce odors, and reduce the dishwasher's cleaning power. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides a dishwasher filter device, which solves the problems that a single filter can only filter large particles of residue and cannot filter finer residues and debris. The filter is also inconvenient to disassemble during use, making it difficult to clean and prone to bacterial growth and odor.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a dishwasher filter device, comprising a mounting frame, a first connecting frame provided on one side inside the mounting frame, a stainless steel coarse filter fixedly connected inside the first connecting frame, a second connecting frame provided on the other side inside the mounting frame, a stainless steel fine filter fixedly connected inside the second connecting frame, a first sliding groove provided at one end inside the mounting frame, and the surface of the first sliding groove slidingly connected to the surface of the first connecting frame, and a second sliding groove provided on one side of the inner surface of the mounting frame, and the surface of the second sliding groove slidingly connected to the surface of the second connecting frame.
[0006] Preferably, a first handle is fixedly installed on one side of the surface of the first connecting frame.
[0007] Preferably, a third connecting frame is provided at one end of the inner surface of the mounting frame, and a stainless steel filter screen is fixedly connected inside the third connecting frame.
[0008] Preferably, a second handle is fixedly connected to one side of the surface of the second connecting frame.
[0009] Preferably, the mounting frame has a third sliding groove inside, and the surface of the third sliding groove is slidably connected to the surface of the third connecting frame.
[0010] Preferably, a third handle is fixedly installed on one side of the surface of the third connecting frame.
[0011] Preferably, the positions of the first connecting frame, the second connecting frame, and the third connecting frame correspond to each other.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] Through the coordinated operation of the first, second, and third chutes, the stainless steel coarse filter, the stainless steel fine filter, and the stainless steel filter, the dishwasher operates as follows: the stainless steel coarse filter intercepts large particles of food residue; the stainless steel fine filter performs a second filtration of the water, blocking smaller particles of food residue; and finally, the stainless steel filter performs a third filtration of the water. After the dishwasher finishes washing, the stainless steel coarse filter, stainless steel fine filter, and stainless steel filter can be easily removed from the mounting frame using the first, second, and third handles. This facilitates disassembly and cleaning, reduces bacterial growth, prevents odors, and enhances the dishwasher's cleaning power. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 The present invention provides the following technical solution: a dishwasher filter device, including a mounting frame 1, a first connecting frame 2 is provided on one side inside the mounting frame 1, a stainless steel coarse filter 9 is fixedly connected inside the first connecting frame 2, a second connecting frame 3 is provided on the other side inside the mounting frame 1, a stainless steel fine filter 11 is fixedly connected inside the second connecting frame 3, a first sliding groove 5 is provided at one end inside the mounting frame 1, and the surface of the first sliding groove 5 is slidably connected to the surface of the first connecting frame 2, a second sliding groove 6 is provided on one side of the inner surface of the mounting frame 1, and the surface of the second sliding groove 6 is slidably connected to the surface of the second connecting frame 3.
[0023] In this embodiment, the stainless steel coarse filter screen 9 can be pulled out from the inside of the mounting frame 1 by using the first handle 8 in conjunction with the first slide groove 5, which facilitates its disassembly, replacement and cleaning, and reduces bacterial growth.
[0024] In this embodiment, the stainless steel filter screen 13 performs a third filtration of the water inside the dishwasher to ensure that there is no residue in the water before it is discharged, thus avoiding pipe blockage and making the device more convenient and practical.
[0025] In this embodiment, the second handle 10, in conjunction with the second slide 6, can smoothly and quickly pull the stainless steel fine filter screen 11 out from the inside of the mounting frame 1, making it convenient to clean the stainless steel filter screen after washing dishes, avoiding the accumulation of debris and the generation of odors.
[0026] In this embodiment: the third handle 12 works in conjunction with the third slide 7 to facilitate the removal and cleaning of the stainless steel filter screen 13 after washing dishes.
[0027] The working principle and usage process of this utility model are as follows: After the dishwasher finishes washing the dishes, the water mixed with food residue will be initially filtered by the stainless steel coarse filter screen 9 before being discharged, blocking large particles of food residue. Then, the stainless steel fine filter screen 11 will perform a second filtration, blocking smaller particles of food residue. Finally, the stainless steel filter screen 13 will filter the water before discharge.
