Detailed Description
Example 1
As shown in fig. 2 and 3, an inflow heating system of a dish washer includes a rinsing water tank 1 and a main washing water tank 2.
The rinse water tank 1 is used for non-cyclically spraying hot water having a first temperature for rinsing tableware, the preferred range of the first temperature value being between 80-88 degrees celsius, the rinse water tank 1 being built-in with a first heater for heating the water, an optional power of the first heater being 5KW.
The main wash tank 2 is adapted to cyclically spray hot water having a second temperature lower than the first temperature for washing dishes, the second temperature preferably ranging between 55-65 degrees celsius. The main wash tank 2 is built with a second heater for heating water, the power of the second heater preferably being 3KW.
A water inlet pipe 7 is installed on the rinsing water tank 1 and/or the main water tank 2, in this embodiment, the water inlet pipe 7 is installed on the rinsing water tank 1, and water flow is injected into the main water tank 2 from the rinsing water tank 1.
Specifically, the rinsing water tank 1 is communicated with the main water tank 2 through a water pump 3 and a spray pipeline 4, and a spray arm at the tail end of the spray pipeline 4 sprays rinsing water into the main water tank 2, and the rinsing water falls back into the main water tank 2. The rinsing water tank 1 can also be directly communicated with the main water tank 2 through a pipeline, and after the rinsing water tank 1 is filled with water, the water pressure in the rinsing water tank 1 is pressed into the main water tank 2 through the back water inflow.
The volume of the main wash tank 2 is larger than the volume of the rinse tank 1, for example, the volume of the main wash tank 2 is 32L and the volume of the rinse tank 1 is 7L. And the first water level switch 5 and the second water level switch 6 are arranged in the main water tank 2 from low to high, the first water level switch 5 and the second water level switch 6 are respectively connected with a controller, the controller is connected with a valve 8 on the water inlet pipe 7, the valve 8 is an electromagnetic valve, and the valve 8 can be triggered to be closed by the first water level switch 5 or the second water level switch 6.
Wherein, a first temperature sensor 9 and a second temperature sensor 10 are respectively arranged in the rinsing water tank 1 and the main water tank 2, the first temperature sensor 9 and the second temperature sensor 10 are respectively connected with a controller, and the valve 8 is triggered to be opened when the first temperature sensor 9 detects that the second temperature is reached or when the second temperature sensor 10 detects that the second temperature is reached.
When the water level of the main water tank 2 reaches the first water level switch 5, the first water level switch 5 is triggered to send a level conversion signal to the controller, the controller receives the signal and then closes the valve 8 of the water inlet pipe, water inlet is stopped, the two water tanks are simultaneously heated in the first step, when the temperature to be heated reaches a second temperature value (for example, 60 ℃) of the main water tank, the controller opens the valve 8 and continues to feed water to the rinsing water tank 1 and the main water tank 2 until the main water tank 2 reaches the second water level switch 6, the controller triggers the second water level switch 6, the controller closes the valve according to the received signal of the second water level switch 6, water feeding is stopped, and the two water tanks continue to heat the mixed water to the corresponding first temperature (for example, 85 ℃) and the second temperature (for example, 60 ℃) so that the water quantity and the water temperature of the dish washer are ready. The rinsing water tank of the water inlet system is not required to wait until the water temperature of the main water tank rises to the second temperature, so that the time for readiness is shortened.
The water inlet heating method of the water inlet heating system of the dish washer comprises the following steps:
opening a valve 8 of a water inlet pipe to fill water into the rinsing water tank 1 and the main water tank 2;
starting a first heater and a second heater to heat water bodies in the rinsing water tank 1 and the main water tank 2 respectively;
when the water level in the main water tank 2 reaches the first water level switch 5, the first water level switch 5 triggers the controller to close the valve 8 of the water inlet pipe, and water inlet is stopped;
When the water temperature in the rinsing water tank 1 and the water temperature in the main water tank 2 reach the second temperature, triggering the controller to open the valve 8, and continuously filling water into the rinsing water tank 1 and the main water tank 2;
When the water level in the main water tank 2 reaches the position of the second water level switch 6, the second water level switch 6 triggers the controller to close the valve 8;
The first heater and the second heater continue to heat the water in the rinse water tank 1 and the main water tank 2, respectively, until the water temperature in the rinse water tank 1 reaches a first temperature and the water temperature in the main water tank 2 reaches a second temperature, and the dishwasher is ready for water supply.
Example 2
In the above embodiment, since the low-temperature fresh water is injected from the rinse water tank, and the higher-temperature water stored in the rinse water tank flows into the main wash water tank, the difference between the water temperatures of the two water tanks increases, so that the rinse water tank needs more time to heat the mixed water to the first temperature (e.g., 85 ℃) and this also results in an increase in the difference between the time of the two water tanks reaching the set temperature, which has a certain effect on the ready time of the dishwasher.
This embodiment is further improved on the basis of embodiment 1 in order to further solve this problem. As shown in fig. 4, this embodiment is different from embodiment 1 in that a partition 11 is installed in the rinse water tank 1 in the axial direction, and the partition 11 may be fixed to the inner wall of the rinse water tank 1 in the horizontal direction. The partition 11 divides the rinse tank 1 into a first flow passage 12 and a second flow passage 13, the first flow passage 12 is selected to be located above the partition 11 in this embodiment, the second flow passage 13 is located below the partition 11, and the first heater is installed in the second flow passage 13. And communication flow passages are respectively arranged between the front end and the rear end of the partition plate 11 and the front box cover and the rear box cover of the rinsing water tank. The communication flow path includes a split flow path 24 on one side of the inlet pipe 7 and a merging flow path 14 on the other side.
The water inlet pipe 7 extends into the sub-flow channel 24, and water in the water inlet pipe 7 is controlled by a pressure device to selectively flow into the first flow channel 12 or the second flow channel 13. A water outlet pipe 23 is arranged on one side of the converging channel 14 on the rinsing water tank 1, and the water outlet pipe 23 is communicated with a water pump or a spraying pipeline.
The pressure device comprises an auxiliary water pipe and a three-way valve 18, wherein the auxiliary water pipe comprises a main pipe 15, a first branch pipe 16 and a second branch pipe 17 which are parallel to the main pipe 15 and are parallel to each other, and the first branch pipe 16 and the second branch pipe 17 extend into a sub-runner 24 and are positioned on two sides of the water inlet pipe 7 oppositely; the three-way valve 18 is installed at the connection of the first branch pipe 16, the second branch pipe 17 and the main pipe 15, and the three-way valve 18 is used for changing the flow direction of the liquid flowing out from the main pipe.
The end parts of the first branch pipe 16 and the second branch pipe 17 are provided with guide parts 19 which are bent towards one side of the water inlet pipe 7, and the first fluid output by one of the guide parts applies pressure to the second fluid output by the water inlet pipe 7 to change the flow direction of the second fluid, so that the second fluid flows into a flow passage at one side far away from the guide parts. For example, the first fluid output by the flow guiding part 19 of the first branch pipe 16 applies pressure to the second fluid output by the water inlet pipe 7, so that the second fluid flows to the side of the second branch pipe 17, flows into the second flow channel 13, is heated by the first heater in the second flow channel 13, flows into the water outlet pipe 23 by the merging channel 14, and most of water flows are sent to the main wash water tank 2 after being heated by the first heater in the mode, so that the heating efficiency of the main wash water tank 2 is indirectly improved. If the water temperature does not need to be too high to flow into the main washing tank 2, the three-way valve 18 is adjusted, and the first fluid output by the flow guide part 19 of the second branch pipe 17 applies pressure to the second fluid output by the water inlet pipe 7, so that most of water flow directly enters the water outlet pipe 23 from the first flow channel 12 and is not heated by the first heater, and the water temperature entering the main washing tank 2 is reduced.
As shown in fig. 4 and 5, the first and second heaters each include a first heating pipe 20 bent in an XY plane and a second heating pipe 21 bent in an XZ plane, which are vertically installed to increase a contact area with water flow. The first heating pipe 20 and the second heating pipe 21 are fixed by the reinforcing plate 22, the reinforcing plate 22 is installed in the YZ plane, a plurality of installation holes for the first heating pipe and the second heating pipe to penetrate are formed in the reinforcing plate 22, the reinforcing plate 22 prevents the first heating pipe 20 and the second heating pipe 21 from shaking, and the installation reliability of the strip-shaped heating pipes is guaranteed.
