Figure 29 is a structural diagram of a water tank in a hot water supply device according to some embodiments.

As shown in Figure 29, the height of the first temperature sensor 10 is the first height H1, the height of the inner pot 21 is the fifth height H5, and the first height H1 is less than or equal to half of the fifth height H5 (H1≤H5/2 ). The height of the electric heater 85 is the second height He, and the second height He is less than or equal to half of the fifth height H5 (He≤H5/2). For example, the first temperature sensor 101 is provided on the side (upper side) of the electric heater 85 away from the base 4 and located in the middle of the water tank 2 .

Figure 30 is a flowchart of a controller of a hot water supply device according to some embodiments.

As shown in FIG. 30 , when the first coil 81 or the electric heater 85 heats, the controller 895 is configured to perform steps 11 to 14 .

In step 11, the controller 895 determines the heating time Δt of the first coil 81 or the electric heater 85.

For example, when the first coil 81 is heated from the first time t1 to the second time t2, the first heating time Δtr (heating time Δt) of the first coil 81 is the sum of the second time t2 and the first time t1. Difference (△t=t1-t2). Or, when the electric heater 85 heats from the third time t3 to the fourth time t4, the second heating time Δtd (heating time Δt) of the electric heater 85 is the difference between the fourth time t4 and the third time t3 ( △td=t4-t3). It should be noted that the controller 895 includes a timer configured to time the heating time of the water tank 2 . This timer can be implemented in hardware or software.

In step 12, the controller 895 calculates the preset temperature T according to the heating time Δt, the first height H1 and the second height He.

The preset temperature T satisfies the following formula:
T＝a×△t+b×H1+c×Hd+d; (1)

Here, the preset distance Hd is the absolute value of the difference between the first height H1 of the first temperature sensor 101 and the second height He of the electric heater 85 (Hd=|H1-He|), that is, the difference between the first temperature sensor 101 and the electric heater 85 distance between heaters 85. a, b, c, d are preset parameters.

In step 13, the controller 895 calculates the water temperature change temperature ΔT based on the water temperature detected by the first temperature sensor 101 and the heating time Δt.

For example, when the first coil 81 is heated from the first time t1 to the second time t2, the first temperature sensor 101 detects that the water temperature is the first water temperature Tr1 at the first time t1, and detects that the water temperature is the first water temperature Tr1 at the second time t2. Second water temperature Tr2. The first change value ΔTr (water temperature change temperature ΔT) is the difference between the second water temperature Tr2 and the first water temperature Tr1 (ΔTr=Tr2-Tr1). Or, when the electric heater 85 heats from the third time t3 to the fourth time t4, the first temperature sensor 101 detects that the water temperature is the third water temperature Td1 at the third time t3, and detects that the water temperature is the fourth temperature at the fourth time t4. Water temperature Td2. The second change value ΔTd (water temperature change temperature ΔT) is the difference between the fourth water temperature Td2 and the third water temperature Td1 (ΔTd=Td2-Td1).

In step 14, the controller 895 adjusts the operating state of the heat pump or determines the operating state of the electric heater 85 according to the water temperature change temperature ΔT and the preset temperature T.

When the hot water supply equipment 100 uses a heat pump to heat water, the first coil 81 supplies heat to the water in the water tank 2, and the first coil 81 heats from the first time t1 to the second time t2. The first temperature sensor 101 detects that the water temperature in the water tank 2 is the first water temperature Tr1 at the first time t1, and detects that the water temperature in the water tank 2 is the second water temperature Tr2 at the second time t2.

Based on the first time t1 and the second time t2, the controller 895 calculates the first heating time Δtr (heating time Δt) of the first coil 81 . The first heating time Δtr is the absolute value of the difference between the second time t2 and the first time t1 (Δtr=|t2-t1|).

Then, based on the first heating time Δtr, the first height H1 and the second height He, the controller 895 calculates the first preset temperature T0 (preset temperature T). In this case, a=a1, b=b1, c=0, d=c1 in formula (1), the first preset temperature T0 satisfies the following formula:
T0＝a1×△tr+b1×H1+c1; (2)

It should be noted that when the hot water supply equipment 100 only uses a heat pump to heat water, the electric heater 85 is in a closed state. Therefore, the parameters (preset distance Hd) involving the electric heater 85 in formula (1) will not Affects the operation of the hot water supply equipment 100, that is, c=0.

After that, the controller 895 calculates the first change value ΔTr based on the first water temperature Tr1 and the second water temperature Tr2. The first change value ΔTr is the absolute value of the difference between the second water temperature Tr2 and the first water temperature Tr1 (ΔTr=|Tr2-Tr1|).

When the first change value ΔTr is greater than or equal to the first preset temperature T0, the controller 895 determines that the water temperature in the water tank 2 is too high, and controls the heat pump to shut down so that the first coil 81 stops heating the water in the water tank 2 . When the first change value ΔTr is less than the first preset temperature T0, the controller 895 determines that the water temperature in the water tank 2 is low, and controls the heat pump to turn on, so that the first coil 81 heats the water in the water tank 2 .

It should be noted that, since the calculation formula (formula (2)) of the first preset temperature T0 is a binary function with respect to the first heating time Δtr and the first height H1, the first preset temperature T0 can change with The first heating time △tr and the first high It changes with the change of degree H1. In this way, when the controller 895 starts and stops the heat pump according to the first change value ΔTr and the first preset temperature T0, the interference of the first heating time Δtr and the first height H1 on the first preset temperature T0 can be effectively eliminated, improving the efficiency of the heat pump. Calculate the accuracy of the first preset temperature T0.

When the hot water supply equipment 100 uses the electric heater 85 to heat water, the electric heater 85 heats from the third time t3 to the fourth time t4. The first temperature sensor 101 detects that the water temperature in the water tank 2 is the third water temperature Td1 at the third time t3, and detects that the water temperature in the water tank 2 is the fourth water temperature Td2 at the fourth time t4.

Based on the third time t3 and the fourth time t4, the controller 895 calculates the second heating time Δtd (heating time Δt) of the electric heater 85 . The second heating time Δtd is the absolute value of the difference between the fourth time t4 and the third time t3 (Δtd=|t4-t3|).

Then, based on the second heating time Δtd, the first height H1 and the second height He, the controller 895 calculates the second preset temperature Ts (preset temperature T). In this case, a=a2, b=b2, c=c2 in formula (1), the second preset temperature Ts satisfies the following formula:
Ts＝a2×△td+b2×H1+c2×Hd+d; (3)

After that, the controller 895 calculates the second change value ΔTd based on the third water temperature Td1 and the fourth water temperature Td2. The second change value ΔTd is the absolute value of the difference between the fourth water temperature Td2 and the third water temperature Td1 (ΔTd=|Td2-Td1|).

When the second change value ΔTd is greater than or equal to the second preset temperature Ts, the controller 895 determines that the electric heater 85 is operating normally. When the second change value ΔTd is less than the second preset temperature Ts, the controller 895 determines that the electric heater 85 is faulty.

It should be noted that since the calculation formula (formula (3)) of the second preset temperature Ts is a ternary function about the second heating time Δtd, the first height H1, and the preset distance Hd, therefore, the second preset temperature The temperature Ts may change with changes in the second heating time Δtd, the first height H1 and the preset distance Hd. In this way, when the controller 895 determines the operating status of the electric heater 85 based on the second change value ΔTd and the second preset temperature Ts, it can effectively exclude the second heating time Δtd, the first height H1, and the preset distance Hd. The interference of the second preset temperature Ts improves the accuracy of calculating the second preset temperature Ts.

Figure 31 is another structural diagram of a hot water supply device according to some embodiments.

As shown in Figure 31, the hot water supply equipment 100 also includes a relay 106, a first temperature controller 104, a second temperature controller 105, a second temperature sensor 102, a third temperature sensor 103, a wire 107, a connecting wire 108 and a temperature sensor.

The first thermostat 104 is provided with a first probe, and the first probe is filled with liquid. The liquid has thermal expansion and contraction properties. Thermal expansion and contraction characteristics can refer to the characteristics that the volume increases as the temperature increases and the volume decreases as the temperature decreases. For example, after absorbing a certain amount of heat, the temperature of the first probe increases, and the liquid in the first probe expands, so that the volume of the first probe increases and the power circuit of the electric heater 85 is disconnected. After a certain amount of heat is released, the temperature of the first probe decreases, and the liquid in the first probe shrinks, so that the volume of the first probe decreases and the power circuit of the electric heater 85 is connected.

The third temperature sensor 103 and the second temperature controller 105 are connected through a connection line 108 . When the third temperature sensor 103 absorbs the heat of the water in the water tank 2 , the absorbed heat can be transferred to the second thermostat 105 through the connecting wire 108 . The second thermostat 105 is provided with a second probe. The second probe is filled with liquid. After absorbing a certain amount of heat, the temperature of the second probe increases, and the liquid in the second probe expands, so that the volume of the second probe becomes larger. The power circuit of the electric heater 85 is disconnected. After a certain amount of heat is released, the temperature of the second probe decreases, and the liquid in the second probe shrinks, so that the volume of the second probe decreases and the power circuit of the electric heater 85 is connected.

In some embodiments, as shown in Figure 29, the height of the second temperature sensor 102 is the third height H2, and the height of the third temperature sensor 103 is the fourth height H3. The second temperature sensor 102 and the third temperature sensor 103 may be at the same height (H2=H3).

The difference between the first height H1 is the second distance Hd3. When the second temperature sensor 102 and the third temperature sensor 103 are at the same height, the first distance Hd2 and the second distance Hd3 are the same.

In some embodiments, the first distance Hd2 and the second distance Hd3 are respectively smaller than the preset distance Hd.

In step 33, the controller controls the relay 106 to disconnect the power circuit of the electric heater 85 and controls the heat pump to turn off.

In step 34 , the controller controls the relay 106 to connect the power circuit of the electric heater 85 .

After disconnecting the power circuit of the electric heater 85, the controller 895 issues a fault alarm and controls the heat pump and the electric heater 85 to stop heating. By cutting off the power circuit of the electric heater 85 when the current water temperature Tp is greater than or equal to the first limited water temperature, the electric heater 85 can be protected and safety accidents caused by the failure of the electric heater 85 can be avoided.

When the controller 895 determines that at least one of the first current water temperature Tp1 or the second current water temperature Tp2 is greater than or equal to the first set temperature, the controller 895 gives a fault alarm and controls the heat pump to shut down.

Figure 34 is yet another flowchart of a controller of a hot water supply device according to some embodiments.

In some embodiments, as shown in Figure 34, after the controller 895 determines that the current water temperature Tp is greater than or equal to the first limited water temperature, the second temperature sensor 102 detects that the first current water temperature Tp1 is greater than or equal to the first set water temperature. When the temperature is determined and the controller 895 determines that the power loop of the electric heater 85 is not disconnected, the controller 895 is further configured to perform steps 41 to 44.

In step 41, the controller 895 obtains the second current water temperature Tp2 detected by the third temperature sensor 103.

In step 42, the controller 895 determines whether the second current water temperature Tp2 detected by the third temperature sensor 103 is greater than or equal to the second set temperature. If yes, the controller 895 executes step 43; if not, the controller 895 executes step 44.

In step 44, the controller 895 controls the electric heater 85 to operate normally.

This can prevent the electric heater 85 from heating the gas in the water tank 2 when there is no liquid water in the water tank 2, thereby causing the water tank 2 to be damaged due to excessive pressure. In addition, the convective heat transfer between the heated gas and the third temperature sensor 103 will also increase the temperature of the third temperature sensor 103, thereby damaging the temperature sensing device.

It should be noted that, as shown in FIG. 31 , the temperature control switch 898 is provided in the power supply circuit of the electric heater 85 to connect or disconnect the power supply circuit of the electric heater 85 .

In step 52, the controller 895 determines whether the temperature detected by the fourth water temperature sensor 110 is greater than or equal to the third preset temperature, or whether the pressure value P detected by the pressure sensor is greater than or equal to the preset pressure. If yes, the controller 895 executes step 52; if not, the controller 895 executes step 53.

In step 53, the safety valve 86 is controlled to open to release the pressure in the water tank 2.

At step 54, the safety valve 86 is controlled to close.
