Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and in particular to a channel-type four-basket fully automatic dishwasher. Background Art

[0002] A dishwasher is a cleaning appliance that sprays cold or hot water onto dishes to remove dirt and clean them. The dishes are placed in the dishwasher's basket, and the dishwasher's spray system sprays water into the basket, cleaning the dishes.

[0003] Existing dishwashers have the following shortcomings: (1) The dish inlet and dish outlet of the existing dishwasher are the same. After one batch of tableware is put into the dishwasher and cleaned, the next batch of tableware needs to wait until the first batch of tableware is taken out from the original route before it can be put into the dishwasher for cleaning. This makes it inefficient to continuously wash a large number of dishes. (2) Existing dishwashers use hot water to spray onto dishes after washing, and then the dishwasher needs to wait for the hot water to cool down before opening the cabinet. Although this can prevent the steam generated by the hot water from scalding the user, the water generated by the steam after cooling will fall on the dishes, and the heat of the steam will also be wasted; (3) Existing dishwashers place tableware in limited layers within a cabinet of a certain height, which limits the number of different types of tableware from being spray-cleaned at the same time. In addition, the cleaning water from the upper layer of the cabinet will fall to the lower layer, affecting the cleaning effect of the lower layer. In addition, each layer of the cabinet is only equipped with one spray arm that sprays in one direction, which may cause some tableware to not be cleaned thoroughly. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a second sealing component of a lifting door and window type at the first bowl inlet and the second bowl inlet, and provides a first sealing component of a sliding door and window type at the bowl outlet, so that the main box for washing tableware with high-temperature water is sealed and the bowl inlet and bowl outlet of the main box are set as different through-holes. After the storage basket containing clean tableware is taken out from the bowl outlet at the front end of the main box through the second roller along the inner track, the storage basket containing tableware to be washed can be sent from the bowl inlet on one side of the main box through the first roller along the outer track to the inner track in the main box, so that the storage basket for tableware to be washed enters the main box, thereby avoiding the problem of reducing the efficiency of continuous tableware washing by taking out the storage basket containing clean tableware and sending it into the storage basket containing tableware to be washed.

[0016] (2) The present invention is provided with a first spray pipe assembly, so that the first high-pressure hot water pump uses the recycled cleaning water of the circulating water tank to spray the tableware in the storage basket with medium water for multiple times along the first water main pipe, the first water diversion branch, the first connecting pipe and the first water spray arm. The first spray pipe assembly is provided, so that the second high-pressure hot water pump uses the hot water of the high-temperature water tank to spray the tableware in the storage basket with water in multiple directions along the second water main pipe, the second water diversion branch, the second connecting pipe and the rotatable second water spray arm. Thus, the residual dirt on the surface of the tableware is washed away by continuous medium water spraying, and the medium water remaining on the surface of the tableware is washed away by a high-temperature water spraying. Thus, the tableware is thoroughly cleaned while saving hot water for washing. Moreover, the multi-directional spraying of the rotatable water spray arm avoids the incomplete cleaning of some tableware caused by the fixed water spray arm spraying in one direction, thereby improving the cleaning effect of the dishwasher.

[0017] (3) The present invention uses a negative pressure fan to draw the water vapor generated by the hot water used for water spraying from the main box into the cooler, and exchanges heat with the tap water in the heat exchange pipe in the cooler. During the heat exchange process, the hot water generated by the cooling of the water vapor returns to the main box, and the hot water generated by the heating of the tap water is sent along the hot water pipe to the serpentine pipe of the circulating water tank. The hot water in the serpentine pipe can heat the cleaning water in the circulating water tank. The hot water after heat exchange is sent to the high-temperature water tank along the recovery pipe, thereby realizing the heat recovery of the water vapor generated by the high-temperature water used for water spraying of dishes, saving energy.

[0018] (4) The present invention provides a water-interference prevention system between the upper cavity and the lower cavity, wherein the inverted V-shaped plate blocks the washing water after the dishes are washed from the upper cavity from flowing to the storage basket in the lower cavity, and can guide the washing water to the right and rear sides of the inverted V-shaped plate, and then flow along the water guide plate to the bottom of the storage basket in the lower cavity, thereby preventing the washing water in the upper cavity from falling onto the storage basket in the lower cavity and contacting the dishes therein, causing certain contamination to the dishes, thereby affecting the cleaning effect of the dishes in the lower cavity.

[0019] (5) The present invention uses an inverted V-shaped plate combined with a water guide plate to allow the cleaning water in the upper chamber to flow along the water guide plate to the bottom of the storage basket in the lower chamber, so that the cleaning water in the upper chamber and the cleaning water in the lower chamber are filtered through the filter net and then fall into the circulating water tank, thereby realizing the recovery of the cleaning water. Once the cleaning water recovered in the circulating water tank is full, it can flow to the outside through the overflow pipe for continued use, thus saving water resources. At the same time, water vapor is pumped into the cooler for heat exchange with the heat exchange pipe. The hot water generated by the heat exchange heats the cleaning water recovered in the circulating water tank. Subsequently, the temperature of the recovered water in the circulating water tank is detected by a temperature sensor. The control panel controls the heating element according to the temperature signal to heat the recovered cleaning water to the required temperature, so that the recovered cleaning water can be reused for spraying dishes, thereby realizing multiple uses of the cleaning water. In addition, the hot water used to heat the recovered cleaning water is sent to the high-temperature water tank through the recovery pipe for continued use, saving resources and energy and reducing costs.

[0058] Specifically, under the pressure of the second high-pressure hot water pump 21, the hot water in the high-temperature water tank 12 is sprayed along the second water diversion main pipe 601, the second water diversion branch 602, the second connecting pipe 603 and the second water spray arm 604 to wash the tableware in the storage basket 13 in multiple directions.

[0059] In this embodiment, if Figure 11 As shown, a heating element 28, a temperature sensor 29, a liquid level sensor 30 and an anti-dry-burning sensor 31 are provided in the circulating water tank 11 and the high-temperature water tank 12. The cooler 701, the circulating water tank 11 and the high-temperature water tank 12 are all connected to the tap water pipe through a water inlet pipe 32, and a solenoid valve 33 is provided on the water inlet pipe 32.

[0060] In this embodiment, if Figure 3 As shown, the side box 10 is divided into four inner chambers by three partitions 37, and a control panel 34, a high-temperature water tank 12, a second high-pressure hot water pump 21 and a first high-pressure hot water pump 20 are respectively installed in the inner chambers. The partition 37 between the high-temperature water tank 12 and the second high-pressure hot water pump 21 is provided with a through hole for connecting the high-temperature water tank 12 and the second high-pressure hot water pump 21. A touch screen 35 and several indicator lights 36 are provided on the front side panel surface of the side box 10.

The rear side panel of the side box 10 is provided with heat dissipation ports corresponding to the second high-pressure hot water pump 21 and the first high-pressure hot water pump 20.

[0061] Specifically, the temperature of the water in the circulating water tank 11 or the high-temperature water tank 12 is detected by the temperature sensor 29, and the detection signal of the temperature is sent to the control panel 34. The control panel 34 controls the heating element 28 to heat the water in the circulating water tank 11 or the high-temperature water tank 12 according to the temperature detection signal to reach the temperature of the water used for the intermediate water spraying or the upper water spraying. The heating temperature of the water used for the intermediate water spraying in the circulating water tank 11 is 60-70°C, and the heating temperature of the water used for the upper water spraying in the high-temperature water tank 12 is 86-96°C. The water level of the circulating water tank 11 or the high-temperature water tank 12 is detected, and a detection signal of the water level is sent to the control panel 34. The control panel 34 controls whether the solenoid valve 33 is opened according to the water level detection signal and replenishes water to the circulating water tank 11 or the high-temperature water tank 12 to achieve sufficient water for spraying and cleaning. The anti-dry-burning sensor 31 is set to prevent the water in the circulating water tank 11 or the high-temperature water tank 12 from drying up due to heating; the first high-pressure hot water pump 20 is controlled to be turned on and off by the control panel to control the number of times the dishes are sprayed with medium water, that is, to adjust the time for spraying the dishes with medium water.

[0062] The working principle of this embodiment is as follows: before the dishwasher washes the dishes, the operator places four storage baskets 13 containing the dishes to be washed on the first outer track 16 and the second outer track 18 in two batches, and aligns the first roller 901 of the storage baskets 13 containing the dishes to be washed with the guide rails of the first outer track 16 or the second outer track 18, so that they can slide on the first outer track 16 or the second outer track 18, then holds the first sliding arm 405 and slides it upward in the first sliding hole 403, so that the falling door window 401 slides upward and the top of it is stuck in the first slot 407, opening the first bowl inlet 104, holds the second sliding arm 406 and slides it downward in the second sliding hole 404, so that the lifting door window 402 slides downward and the bottom of it is stuck in the second slot 408, opening the second bowl inlet 105, and under the action of the first roller 901, the two batches of storage baskets 1 containing the dishes to be washed are placed in the dishwasher. 3. The first outer rail 16 and the second outer rail 18 slide into the main box 1 from the first bowl inlet 104 and the second bowl inlet 105, respectively, and then slide in the main box 1 through the first inner rail 17 and the second inner rail 19, respectively, so that the four storage baskets 13 containing the dishes to be washed slide to the well-type guide rails 26 in the two upper chambers 101 and the two lower chambers 102 of the main box 1. Then, the first sliding arm 405 is grasped and slid downward in the first sliding hole 403, so that the lowering door window 401 slides downward, sealing the first bowl inlet 104. The second sliding arm 406 is grasped and slid upward in the second sliding hole 404, so that the lifting door window 402 slides upward, sealing the second bowl inlet 105. At the same time, the left sliding door window 302, the right sliding door window 303 and the left and right frames of the door frame 301 are kept sealed, thereby keeping the main box 1 containing the dishes to be washed sealed. When the dishwasher starts to wash dishes, the operator presses the power button on the touch screen 35 to power on the dishwasher, and the corresponding indicator light 36 lights up. The operator sets the number of times the medium water is sprayed on the dishes on the touch screen 35, that is, sets the medium water spraying time for the dishes. At this time, the control panel 34 controls the solenoid valve 33 to add tap water to the circulating water tank 11. The liquid level sensor 30 detects that the circulating water tank 11 has reached the required water volume. The control panel 34 controls the solenoid valve 33 to close according to the water volume detection signal, and then controls the heating element 28 to heat the water in the circulating water tank 11. When the temperature sensor 29 detects that the water temperature in the circulating water tank 11 reaches 60-70°C, the control panel 34 controls the heating element 28 to close according to the temperature detection signal, and then starts the first high-pressure hot water pump 20 to let the high-temperature water in the circulating water tank 11 enter the first water spray arm 504 located above and below the storage basket 13 along the first water diversion main pipe 501, the first water diversion branch 502 and the first connecting pipe 503. The two first water spray arms 50 4 Under the driving force of water pressure, the high-temperature water is sprayed onto the tableware in the storage basket 13 in multiple directions through the nozzles, thereby completing a medium-water spraying of the tableware. Since there is sufficient hot water in the circulating water tank 11, and after spraying, the washing water in the upper cavity 101 is guided to the right and rear sides of the inverted V-shaped plate 201 under the blocking of the inverted V-shaped plate 201, and then flows along the right water guide plate 202 and the rear water guide plate 203 to the bottom of the storage basket 13 in the lower cavity 102 to prevent water from flowing, so that these washing waters pass through the filter screen 14 together with the washing water in the lower cavity 102. The filter screen 14 filters the impurities in the washing water and then the circulating water tank 11 recycles the washing water. In this way, the water in the circulating water tank 11 can be recycled so that there is sufficient usable water therein. The first high-pressure hot water pump 20 can be started continuously to spray the tableware with medium-water for multiple times until the medium-water spraying time of the tableware is completed. At this time, the residue and dirt on the tableware are rinsed off, and the surface of the tableware is clean. The control panel 34 controls the first high-pressure hot water pump 20 to be turned off. Since there is residual cleaning water on the surface of the tableware, the control panel 34 controls the solenoid valve 33 of the water inlet pipe 32 to open, and tap water is added to the high-temperature water tank 12 from the water inlet pipe 32 along the heat exchange pipe 703, the hot water pipe 802, the heat transfer pipe 801, and the recovery pipe 803. The liquid level sensor 30 detects that the high-temperature water tank 12 has reached the required amount of water. The control panel 34 controls the solenoid valve 33 to close according to the water amount detection signal, and then controls the heating element 28 to heat the water in the high-temperature water tank 12. When the temperature sensor 29 detects that the water in the high-temperature water tank 12 reaches 86-96°C, the control panel 34 controls the heating element 28 to close according to the temperature detection signal, and then controls the second high-pressure hot water pump 21 to transfer 2 / 3 of the high-temperature water in the high-temperature water tank 12 along the second water diversion main pipe 601, the second water diversion branch 602 and the second connecting pipe 603 within 25 seconds. In the second water spray arms 604 above and below the storage basket 13, the two second water spray arms 604 are driven by water pressure to rotate and spray high-temperature water onto the tableware in the storage basket 13 in multiple directions through the spray port, thereby completing the water spraying of the tableware and cleaning the residual cleaning water on the surface of the tableware. After spraying, the cleaning water of the upper cavity 101 is blocked by the inverted V-shaped plate 201 and diverted to the right and rear sides of the inverted V-shaped plate 201, and then flows along the right water guide plate 202 and the rear water guide plate 203 to the bottom of the storage basket 13 in the lower cavity 102, so as to achieve the purpose of preventing water from flowing, so that these cleaning waters fall into the circulating water tank 11 together with the cleaning water of the lower cavity 102. Once the water level in the circulating water tank 11 is higher than the installation height of the overflow pipe 15 at the circulating water tank 11, the overflowing recovered cleaning water flows to the outside from the overflow pipe 15 to prevent the circulating water tank 11 from being filled with cleaning water; The control panel 34 controls the second high-pressure hot water pump 21 to start water supply and spraying, and at the same time controls the negative pressure fan 702 to start, pumping water vapor generated by the high-temperature water from the main tank 1 into the cooler 701, where it exchanges heat with the tap water in the heat exchange pipe 703 in the cooler 701. During the heat exchange process, the hot water generated by the cooling of the water vapor returns to the main tank 1, while the hot water generated by the heating of the tap water is sent along the hot water pipe 802 to the heat transfer pipe 801 of the circulating water tank 11. The hot water in the heat transfer pipe 801 can be used to recover heat from the washing water in the circulating water tank 11 to heat it. The hot water after heat exchange is then sent along the recovery pipe 803 to the high-temperature water tank 12 for heating and use. After the heat of the water vapor generated by the hot water used for water spraying is recovered and the washing water generated after washing the dishes is recovered, the corresponding indicator light 36 of the control box of the control panel 34 lights up to indicate that the dishes in the storage basket 13 have been cleaned. The operator slides the left sliding door window 302 to the right frame of the door frame 301, and then pulls the two storage baskets 13 containing cleaned dishes in the cavity structure on the left side of the main box 1 forward along the first inner track 17 and the second inner track 19 under the action of the second roller 902 and takes them out from the first bowl outlet 103A and the third bowl outlet 103C. Then, slide the left sliding door window 302 and the right sliding door window 303 to the left frame of the door frame 301, and pull the two storage baskets 13 containing cleaned dishes in the cavity structure on the right side of the main box 1 forward along the first inner track 17 and the second inner track 19 under the action of the second roller 902 and take them out from the second bowl outlet 103B and the fourth bowl outlet 103D.
