[0023] The present invention provides a double-layer vertical flip-cover dishwasher, such as Figure 1-2 As shown, it includes a box body 1 which is divided into a drying chamber 11, a cleaning chamber 12 and a liquid supply chamber 13 from top to bottom in sequence. A bowl frame 2 arranged in a double layer and used for holding tableware is placed in the cleaning chamber 12 of the box body 1. A plurality of spray components 3 located at different heights and used for spraying cleaning liquid to the bowl frame 2 are arranged in the cleaning chamber 12 of the box body 1. A liquid supply component 4 for providing cleaning liquid is arranged in the liquid supply chamber 13 of the box body 1. A main liquid infusion pipe 5 for conveying cleaning liquid to the spray component 3 is arranged on the liquid outlet of the liquid supply component 4. A drying component 6 for providing hot air to the cleaning chamber 12 is arranged in the drying chamber 11 of the box body 1; the main liquid infusion pipe 5 is connected to the spray component 3, and its inner diameter gradually decreases from bottom to top to reduce the spray pressure difference between the spray components 3 located at different heights.
[0024] In this embodiment, the box body 1 is welded by stainless steel square tubes and stainless steel iron sheets, and is divided from top to bottom into a drying chamber 11 for installing a drying component 6, a cleaning chamber 12 for placing two layers of bowl frames 2 and for installing spray components 3, and a liquid supply chamber 13 for installing a liquid supply component 4 and a control module. The main infusion pipe 5 is vertically installed on the back of the box body 1 (opposite to the observation door 14), and is fixed to the three spray components 3 by conventional connectors. From top to bottom, the first spray component 3 sprays the cleaning liquid on the top surface of the upper bowl frame 2, the second spray component 3 sprays the cleaning liquid on the top surface of the lower bowl frame 2, and the third spray component 3 sprays the cleaning liquid on the bottom surface of the lower bowl frame 2. The liquid inlet of the main infusion tube 5 is connected to the liquid outlet of the liquid supply assembly 4 through a transfer tube, and the tube body is provided with three liquid outlets at different heights, the top liquid outlet is connected to the liquid inlet of the top spray assembly 3, the bottom liquid outlet is connected to the liquid inlet of the bottom spray assembly 3, and the middle liquid outlet is connected to the liquid inlet of the middle spray assembly 3. The main infusion tube 5 is welded by two sections of stainless steel pipes with different inner diameters, namely an upper infusion tube 52 and a lower infusion tube 51, the top of the upper infusion tube 52 is the liquid outlet connected to the liquid inlet of the top spray assembly 3, the top of the lower infusion tube 51 is the liquid outlet connected to the liquid inlet of the middle spray assembly 3, and the bottom of the lower infusion tube 51 is the liquid outlet connected to the liquid inlet of the bottom spray assembly 3. The main infusion pipe 5 is set with its inner diameter gradually decreasing from bottom to top, which offsets the pressure loss caused by the height difference, so that the spray components 3 located at different heights spray cleaning liquid with almost equal pressure to clean the tableware, thereby reducing the difference in cleanliness of the two layers of tableware.
[0025] Furthermore, the liquid supply component 4 includes an integrated main water tank 41 for containing detergent and clean water, a rinsing water tank 42 for containing clean water, a first water pump 43 and a second water pump 44; the liquid inlet of the first water pump 43 is connected to the interior of the integrated main water tank 41, and its liquid outlet is connected to the main infusion pipe 5; the liquid inlet of the second water pump 44 is connected to the interior of the rinsing water tank 42, and its liquid outlet is connected to the spray component 3 through the auxiliary infusion pipe 8; the upper end of the integrated main water tank 41 is set to a funnel shape and is used for the water inlet for recovering detergent and clean water; the integrated main water tank 41, the rinsing water tank 42, the first water pump 43, and the second water pump 44 are all arranged in the liquid supply bin 13 of the box body 1.
[0026] Furthermore, the spray assembly 3 includes a main nozzle 31 for spraying detergent and clean water and a rinsing nozzle 32 for spraying clean water; the main nozzle 31 and the rinsing nozzle 32 are fixedly connected and fixedly arranged in the cleaning chamber 12; the main nozzle 31 is connected to the main infusion pipe 5, and the rinsing nozzle 32 is connected to the auxiliary infusion pipe 8.
[0027] like Figure 2-7As shown, the water inlet of the integrated main water tank 41 is used to receive the cleaning liquid formed by detergent and clean water. The water inlet is funnel-shaped as a whole and has a certain depth, so as to better prevent the leakage of the cleaning liquid; a filter screen (not shown in the figure) is overlapped at the bottom of the water inlet to prevent food residues from entering the integrated main water tank 31. The bottom of the integrated main water tank 41 is also provided with a waste outlet 411 for discharging the cleaning liquid that can no longer be used, which is used for regular maintenance of the dishwasher. When cleaning, the first water pump 43 first runs for a certain time, and the cleaning liquid in the integrated main water tank 41 is sprayed on the tableware of the bowl frame 2 through the main infusion pipe 5 and the main nozzle 31, and then the second water pump 44 runs for a certain time again, and the clean water in the rinse water tank 32 is sprayed on the tableware of the bowl frame 2 through the auxiliary infusion pipe 8 and the rinse nozzle 32. This design cleans the tableware in a mode of first cleaning and then rinsing, which can effectively save water resources.
[0028] like Figure 2-7 As shown, the main nozzle 31 is generally S-shaped, and a plurality of water outlets in different directions are provided on the surface facing the bowl frame 2; the rinsing nozzle 32 is generally linear, and a plurality of water outlets in different directions are provided on the surface facing the bowl frame 2; the middle part of the main nozzle 31 and the middle part of the rinsing nozzle 32 are fixedly connected through a threaded structure, but the rinsing nozzle 32 can be rotated at a certain angle on the main nozzle 31, so as to adjust the spraying direction of the rinsing nozzle 32 according to actual needs. The main nozzle 31 sprays cleaning liquid through the first water pump 43 to perform main cleaning on the tableware; the rinsing nozzle 32 sprays clean water through the second water pump 44 to rinse the tableware.
[0029] Furthermore, at least one heating rod 7 is disposed inside the integrated main water tank 41 and inside the rinse water tank 42 .
[0030] like Figure 2-7 As shown, a heating rod 7 is installed inside the integrated main water tank 41, and two heating rods 7 are installed inside the rinse water tank 42; the heating rod 7 can heat the cleaning liquid and the cleaning agent, providing the dishwasher with a better cleaning effect for the tableware, especially when there is a lot of oil on the tableware or in cold winter.
[0031] like Figure 2-7 As shown, the rinse water tank 42 is composed of a main box body and a rinse upper cover 422, and the rinse upper cover 422 is buckled on the upper end of the main box body; a water baffle 421 is installed in the middle of the main box body, and the water baffle 421 divides the internal space of the main box body from top to bottom into a water inlet area and a heating area. The side wall of the main box body is provided with a water inlet pipe for introducing clean water into the water inlet area. The clean water in the water inlet area flows into the heating area through the water inlet through hole located at the bottom thereof. The double-layer structure of the rinse water tank 42 allows the clean water to flow from the water inlet area to the heating area from top to bottom, which improves the heating efficiency and saves energy to a certain extent.
[0032] In addition, the integrated main water tank 41 is arranged adjacent to the rinse water tank 42, so that the cleaning liquid in the integrated main water tank 41 and the clean water in the rinse water tank 42 can exchange heat and preheat the clean water entering the water inlet area, further improving the heating efficiency and saving electricity.
[0033] Furthermore, the air suction port 63 of the drying component 6 is communicated with the top of the cleaning chamber 12 , and the air outlet thereof is communicated with the bottom of the cleaning chamber 12 .
[0034] like Figure 2-4 As shown, the drying assembly 6 is a relatively conventional hot air blower assembly, which is mainly composed of a blower 61 and an electric heating wire group 62, and is installed in the drying chamber 12. The air suction port 63 of the drying assembly 6 is obliquely downward facing the front of the box body 1 (towards the observation door 14) to suck air, and its air outlet end conveys hot air to the bottom of the washing chamber 12 through two square air supply pipes 64, thereby forming a hot air circulation airflow from bottom to top to dry the tableware. The two square air supply pipes 64 are respectively located on both sides of the bowl frame. The hot air is blown from the lower bowl frame 2 into the upper bowl frame 2 in the washing chamber 12 through multiple air guide plates 16, thereby drying the rinsed tableware. The air guide plate 16 is a 90-degree angle plate, which is fixed on the square air supply pipe 64 by welding, and there are four of them, that is, each layer of the bowl frame 2 corresponds to two air guide plates 16, thereby conveying a part of the hot air more accurately and comprehensively to the surface of the tableware, accelerating the evaporation of the water droplets remaining on the surface of the tableware, thereby improving the drying effect and drying speed.
[0035] Furthermore, an observation door 14 is hinged on the front of the cleaning chamber 12 of the box body 1, and roller sets 141 are rotatably provided at both ends of the inner side of the observation door 14 for movably abutting the bottom of the bowl frame 2 to facilitate the bowl frame 2 to slide into the cleaning chamber 12.
[0036] like Figure 1 , Figure 2 and Figure 8 As shown, the bottom end of the observation door 14 is hinged on the front of the box body 1, and door locks 143 are welded on the left and right sides of the top thereof. A tempered glass 142 is installed in the middle, and roller groups 141 are installed on the left and right sides thereof. The opening and closing angle of the observation door 14 is 90 degrees, which is achieved by a conventional limiting structure; when taking out or loading the bowl frame 2, it is in an open state and placed horizontally. The roller group 141 is a belt-shaped wheel group composed of a plurality of rollers, which is used to support the bottom of the bowl frame 2. A receiving plate 15 (a 90-degree angle plate) for supporting the bowl frame 2 is welded inside the box body 1. The receiving plate 15 and the horizontally placed roller group 141 are almost at the same level, which is convenient for the user to take out the bowl frame 2 from the cleaning bin 12 or put the bowl frame 2 into the cleaning bin 12.
[0037] In addition, a magnetic contact switch 17 for sensing whether the observation door 14 is in an open state or a closed state is installed at a position corresponding to the box body 1 and the observation door 14; when the observation door 14 is in an open state, the blower 61, the first water pump 43 and the second water pump 44 are all in a non-working state to prevent the user from being scalded when accidentally opening the observation door 14.
[0038] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
