In some embodiments, the baffle 2 is configured such that its rotational speed V is dynamically adjustable, the rotational speed V of the baffle 2 = 100%, (Ti-Ta)/(Tt-Tb);
wherein Ti is the detected temperature of the refrigerant in the heat exchange coil 5; ta is the detected outlet water temperature of the water tank 1; tt is a target temperature of the water tank 1 set by the user, and Tb is a real-time temperature of the detected water tank 1.
The rotation speed of the separator 2 can be dynamically adjusted according to v=100% (Ti-Ta)/(Tt-Tb).
For example: setting the rotating speed range V of the partition board 2 to be 0-100%;
Detecting a water tank temperature difference deltat=a target temperature Tt of the water tank 1 set by a user-detecting a real-time temperature Tb of the water tank 1, the Tb taking the temperature of the water tank at a position where the average temperature can be represented;
detected refrigerant temperature Ti in the heat exchange coil and detected water outlet temperature Ta of the water tank, V=100% (Ti-Ta)/DeltaT
When the Ti-Ta is larger and V is increased, the fact that the water tank is rapidly heating is indicated, and the heat exchange rate inside the water tank needs to be improved; an increase in deltat will result in a decrease in V, indicating a greater tank temperature differential at this time.
The heat exchange rate in the lifting water tank is the heat exchange rate between the refrigerant in the heat exchange coil and the water in the water tank on the premise that the temperature of the refrigerant in the heat exchange coil is greatly different from the water outlet temperature of the water tank, namely on the premise that Ti-Ta is large; the fact that the temperature difference of the water tank is larger, namely deltaT is larger, indicates that the real-time temperature of the water tank 1 detected at the moment is far away from the target temperature of the water tank 1 set by a user, the temperature of the water tank needs to be stabilized, the external machine is enabled to stably load, the temperature of a refrigerant in the heat exchange coil is increased, namely Ti, and the heat exchange rate does not need to be increased.
In some embodiments, the separator 2 is configured such that the distance H that it moves is dynamically adjustable, the distance h=l×tb×100%/Tt that the separator 2 moves.
Where Tt is a target temperature of the water tank 1 set by the user, tb is a real-time temperature of the water tank 1 detected, and L is a maximum distance at which the partition plate 2 can move within the water tank 1.
The movement distance of the separator 2 can be dynamically adjusted according to h=l×tb×100%/Tt.
Some embodiments also provide a method for adjusting the water heater, which includes:
when high temperature water is required to be prepared, the partition plate 2 is moved, so that the volume of the first area is minimized;
Then, according to the formula h=l×tb×100%/Tt, dynamically moving the partition plate 2 in a direction to increase the volume of the first region, the distance by which the partition plate 2 moves being H;
where Tt is a target temperature of the water tank 1 set by the user, tb is a real-time temperature of the water tank 1 detected, and L is a maximum distance at which the partition plate 2 can move within the water tank 1.
Closest to Tt at Tb, h=l.
That is, when Tb is closest to Tt, the proportionality coefficient is closest to 1, which means that the water in the water tank reaches the target value, the volume needs to be increased, the water amount is increased, and the water demand of the customer is met, the partition plate 2 is lowered, and the volume of the first area is increased to the maximum;
Of course, the distance of movement of the separator may be set directly according to the user's needs.

Wherein the second plate 22 is provided with a third plate 23 extending towards the first area, and the rotation of the third plate 23 is utilized to make the rapid heat exchange area form a turbulent flow area in the process of rotating the partition board 2 so as to accelerate heat exchange; the second plate 22 cooperates with the first plate 21 to provide a layered thermal insulation.
The first power piece drives the telescopic rod 31 to stretch out and draw back, drives the partition plate 2 to lift, and changes the volumes of the high-speed heat exchange area and the heat exchange area to be subjected to heat exchange. During lifting and lowering of the partition plate 2, the second plate 22 partially covers the area formed between the adjacent two first plates 21 or does not cover the area formed between the adjacent two first plates 21 at all. After the second plates 22 are rotated and lifted, the areas formed between the adjacent two first plates 21 are completely covered, and a flat and sealed disc is formed.
As shown in fig. 5, in this embodiment, the process of controlling the disturbance of the separation in the water tank 1 of the water heater is as follows:
the user sets the water temperature at the PC (personal computer) end;
The temperature in the water tank 1 is collected through the temperature sensing bag, a signal is sent to the PC end, the PC end compares the water temperature in the water tank 1 sent by the temperature sensing bag with the water temperature set by a user, whether quick water heating is needed or not is judged, and if the quick water heating is not needed, the process is ended. If the water needs to be heated quickly, a mode of heating water quickly is started, and the layered heat insulation disturbance device is started.
The operation principle of the rapid heating water mode is as follows: according to the information fed back by the PC end calculation, it is determined whether the telescopic rod 31 needs to be adjusted in telescopic height, if the telescopic height of the telescopic rod 31 needs to be adjusted, the telescopic height of the telescopic rod 31 is adjusted first, and if the telescopic height of the telescopic rod 31 does not need to be adjusted, the second plate 22 is adjusted through the second power mechanism 4.
During the process of stretching the telescopic rod 31 to drive the partition plate 2 to move, the second plate 22 partially covers the area formed between the two adjacent first plates 21 or does not cover the area formed between the two adjacent first plates 21 at all. At this time, the second plate 22 and the first plate 21 have a mutual overlapping portion, and the area between the two first plates 21 is not completely covered by the second plate 22, that is, a passage allowing water to pass through is formed between the two first plates 21.
The second power member drives the second mounting seat 42 to move in a direction away from the first mounting seat 41, the second plate 22 moves in a direction away from the first plate 21, then the second mounting seat 2 rotates to drive the second plate 22 to rotate, and after reaching a set angle, the second plate 22 completely covers an area between the two first plates 21. The second mounting seat 42 drives the second plate 22 to move towards the first plate 21, the second plate 22 and the first plate 21 form a finished circular plate, the circular plate is matched with the cross section shape in the water tank 1, the first plate 21 and the second plate 22 are matched to form a separation heat insulation layer, and the inner container of the water tank 1 is divided into an upper area and a lower area, namely a first area and a second area.
According to the calculation of the PC end, whether rotation disturbance is carried out is judged, if rotation disturbance is not needed, the process is ended, if rotation disturbance is needed, rotation of the partition board 2 is controlled, at the moment, the first board 21, the second board 22 and the third board 23 are used as a whole to synchronously rotate, the rotation speed of the partition board 2 is controlled, the intensity of the water flow turbulence phenomenon of the quick heat exchange area is controlled, heat exchange between water of the quick heat exchange area and the heat exchange coil is accelerated, and the water temperature in the water tank liner can quickly reach the user requirement.
In summary, when the water is required to be heated at a high speed, the water tank liner can be divided into two areas by the control of the layered heat insulation disturbance device, the size of the divided areas can be determined according to the heat exchange volume, and the control of the required heat exchange volume is realized by adjusting the telescopic height of the telescopic rod 31. And the rotating speed of the partition plate 2 can be controlled according to the requirements, so that the intensity of the water flow turbulence phenomenon of the rapid heat exchange area is controlled, the heat exchange between the water in the rapid heat exchange area and the heat exchange coil is quickened, the requirements of users on rapid water heating are met, the water heating capacity is improved, and the power and the load of a unit are reduced.
The first power mechanism 3 drives the partition board 2 to move in the water tank 1 and drives the partition board 2 to rotate, the second power mechanism 4 drives the second board 22 to move along the central axis of the water tank 1 and drives the second board 22 to rotate around the central axis of the water tank 1, and the power piece and the adaptive transmission mechanism adopted can be realized by adopting a conventional technology and are not repeated herein.
