Detailed Description
Example 1
As shown in fig. 2 and 3, an inlet water heating system of a dishwasher includes a rinse water tank 1 and a main wash water tank 2.
The rinse water tank 1 is used for non-cyclically spraying hot water having a first temperature, preferably ranging between 80-88 degrees celsius, for rinsing dishes, the rinse water tank 1 houses a first heater for heating the water, an optional power of which is 5 KW.
The main wash tank 2 is used to cyclically spray hot water having a second temperature, lower than the first temperature, to wash dishes, the second temperature preferably ranging between 55-65 degrees celsius. A second heater is arranged in the main washing water tank 2 to heat water, and the power of the second heater is preferably 3 KW.
The rinsing water tank 1 and/or the main washing water tank 2 are/is provided with a water inlet pipe 7, in the embodiment, the water inlet pipe 7 is arranged on the rinsing water tank 1, and water flow is injected into the main washing water tank 2 from the rinsing water tank 1.

Or the rinsing water tank 1 can be directly communicated with the main rinsing water tank 2 through a pipeline, and when the rinsing water tank 1 is filled with water, the later water inflow presses the water in the rinsing water tank 1 into the main rinsing water tank 2.
The volume of the main wash water tank 2 is larger than the volume of the rinse water tank 1, for example, the volume of the main wash water tank 2 is 32L, and the volume of the rinse water tank 1 is 7L. And a first water level switch 5 and a second water level switch 6 are arranged in the main washing 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 a water inlet pipe 7, the valve 8 is an electromagnetic valve, and the valve 8 can be triggered by the first water level switch 5 or the second water level switch 6 to be closed.
Wherein, install first temperature sensor 9 and second temperature sensor 10 in rinsing water tank 1 and the main wash water tank 2 respectively, first temperature sensor 9 and second temperature sensor 10 are connected with the controller respectively, and valve 8 is triggered and is opened when reaching the second temperature by first temperature sensor 9 detection, or when reaching the second temperature by second temperature sensor 10 detection.
When the water level of the main washing 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 closes the valve 8 of the water inlet pipe after receiving the signal, water inflow is suspended, the two water tanks are simultaneously heated for the first step, when the heating temperature reaches a second temperature value (for example, 60 ℃) of the main washing water tank, the controller opens the valve 8, water continues to be supplied to the rinsing water tank 1 and the main washing water tank 2, the second water level switch 6 is triggered until the main washing water tank 2 reaches the second water level switch 6, the controller closes the valve according to the received signal of the second water level switch 6, water supply 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 volume and the water temperature of the dishwasher are ready. The rinsing water tank of the water inlet system is not required to be ready after the water temperature of the main washing water tank is raised to the second temperature, so that the time for preparing the rinsing water tank is shortened.
The water inlet heating method of the dishwasher water inlet heating system comprises the following steps:
opening a valve 8 of the water inlet pipe, and injecting water into the rinsing water tank 1 and the main washing water tank 2;
starting a first heater and a second heater to respectively heat the water bodies in the rinsing water tank 1 and the main washing water tank 2;
when the water level in the main washing 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 suspended;
when the water temperature in the rinsing water tank 1 and the water temperature in the main washing water tank 2 reach a second temperature, triggering the controller to open the valve 8, and continuously injecting water into the rinsing water tank 1 and the main washing water tank 2;
when the water level in the main washing water tank 2 reaches 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 respectively continue to heat the water in the rinsing water tank 1 and the main water tank 2 until the water temperature in the rinsing water tank 1 reaches the first temperature and the water temperature in the main water tank 2 reaches the second temperature, and the water supply of the dishwasher is ready.
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 temperature difference between the mixed water in the two tanks is increased, so that the rinse water tank needs more time to heat the mixed water to the first temperature (for example, 85 ℃), which also causes the increase of the time difference between the two tanks reaching the set temperature, and has a certain influence on the ready time of the dishwasher.
This embodiment is an improvement on embodiment 1 to further solve this problem. As shown in fig. 4, this embodiment is different from embodiment 1 in that a partition plate 11 is installed in the rinse water tank 1 in the axial direction, and the partition plate 11 can be fixed to the inner wall of the rinse water tank 1 in the horizontal direction. The baffle 11 divides the rinsing water tank 1 into a first flow passage 12 and a second flow passage 13, wherein the first flow passage 12 is selected to be positioned above the baffle 11 in the embodiment, the second flow passage 13 is selected to be positioned below the baffle 11, and the first heater is installed in the second flow passage 13. Communicating flow channels are arranged between the front end and the rear end of the clapboard 11 and the front box cover and the rear box cover of the rinsing water tank. The communication flow path includes a branch flow path 24 on one side of the water inlet pipe 7 and a merging flow path 14 on the other side.
The water inlet pipe 7 extends into the branch channel 24, and the 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 confluence passage 14 on the rinsing water tank 1, and the water outlet pipe 23 is communicated with a water pump or a spray pipeline.
The pressure device comprises an auxiliary water pipe and a three-way valve 18, the auxiliary water pipe comprises a main pipe 15 and a first branch pipe 16 and a second branch pipe 17 which are connected in parallel with the main pipe 15 and are mutually parallel, and the first branch pipe 16 and the second branch pipe 17 extend into the branch flow passage 24 and are oppositely positioned at two sides of the water inlet pipe 7; a three-way valve 18 is installed at the junction 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 formed with flow guide parts 19 which are bent towards one side of the water inlet pipe 7, and the first fluid output by one of the flow guide parts exerts pressure on 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 the flow channel on one side far away from the flow guide parts. For example, the first fluid output from the diversion part 19 of the first branch pipe 16 applies pressure to the second fluid output from the water inlet pipe 7, so that the second fluid flows to the second branch pipe 17 side, then flows into the second flow passage 13, is heated by the first heater in the second flow passage 13, and then flows into the water outlet pipe 23 through the merging passage 14, and most of the water flow is heated by the first heater and then sent into the main wash water tank 2 in this mode, thereby indirectly improving the heating efficiency of the main wash water tank 2. If the water temperature does not need to be too high, the three-way valve 18 is adjusted, the first fluid output from the diversion part 19 of the second branch pipe 17 applies pressure on the second fluid output from the water inlet pipe 7, so that most of the water flow directly enters the water outlet pipe 23 from the first flow passage 12 without being heated by the first heater, and the temperature of the water entering the main wash water tank 2 is reduced.
As shown in fig. 4 and 5, the first heating pipe is mounted in a vertical manner, and the first heating pipe 20 is bent in the XY plane and the second heating pipe 21 is bent in the XZ plane, so that the contact area with the water flow is increased. 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 a YZ plane, a plurality of installation holes for the first heating pipe and the second heating pipe to penetrate through 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 pipe is guaranteed.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
