Description of drawings
Fig. 1 is the system construction drawing of hot water machine in the embodiment of the invention;
Fig. 2 is the flow chart of system control method in the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated:
As shown in Figure 1, it has illustrated the system construction drawing of hot water machine of the present invention, and it includes circulation line 1 and directly-heated pipeline 2, and wherein, the structure of said circulation line 1 and directly-heated pipeline 2 has belonged to prior art, and the present invention repeats no more at this.The circulation heating mode is: the water that the water circulating pump 8 in the said circulation line 1 extracts in the water tank 10, the water of extraction are got back to water tank 10 again after heating through heat-pump hot-water mechanism 20, through circulation mode repeatedly, with constantly heating and insulation of the water temperature in the water tank 10.Directly heating mode is: the running water that booster pump 9 extraction systems in the said directly-heated pipeline 2 are outer, the running water of extraction injects water tank 10 through heat-pump hot-water mechanism 20 heating backs.Because the temperature of the running water that booster pump 9 extracts is lower, heat-pump hot-water mechanism 20 makes the glassware for drinking water that comes out through direct heating mode that higher temperature arranged through the adjusting of self, can directly satisfy user's user demand.
As shown in Figure 2, it has illustrated the flow chart of the system control method of embodiment among the present invention to be elaborated below to this figure:
A kind of control method of water-heating machine system, this method comprise,
Step 1: water level switch 11 detects the water level in the water tanks 10 and detected water level signal is sent to controller; When controller receives two types of water level signal; Start the direct heating mode of operation, when controller receives one type of water level signal, direct heating mode out of service; Behind the direct heating mode out of service, get into step 2.Said controller receives two types of water level signal and the direct heating mode of startup operation, and water level switch 11 continues sensed water level, when controller receives one type of water level signal, and direct heating mode out of service.Wherein, one type of water level signal is water level water level switch 11 detected water level signal when being higher than the peak level value; Two types of water level signal are water level water level switch 11 detected water level signal when being equal to or less than the lowest water level value.Peak level value and lowest water level value are that the situation such as consumption according to the water in the water tank 10 are provided with; More frequent such as user's water; Consume water is when very fast, and the lowest water level value that sets will can avoid occurring the hot water situation that supply falls short of demand greatly like this.If user's water is fewer, the peak level value that sets just can be smaller, can avoid the energy of being wasted when the water in the water tank 10 is incubated like this.In the present embodiment, the peak level value is 4/5ths of water tank 10 volumes, and the lowest water level value is 2/3rds of water tank 10 volumes.
Step 2: temperature sensor 12 detects the water temperature in the water tanks 10 and detected water temperature signal is sent to controller; When controller receives one type of water temperature signal; When circulation heating mode out of service, controller receive two types of water temperature signals, operation circulation heating mode; Behind the operation circulation heating mode, get into step 3.Said controller receives one type of water temperature signal and circulation heating mode out of service, and temperature sensor 12 continues to detect water temperature, when controller receives two types of water temperature signals, and operation circulation heating mode.
Wherein, one type of water temperature signal is water temperature temperature sensor 12 detected water temperature signals when being higher than the water temperature setting value; Two types of water temperature signals are water temperature temperature sensor 12 detected water temperature signals when being equal to or less than the water temperature setting value.Said water temperature setting value is to be provided with according to concrete situation such as environment for use, and such as the place colder in the north, this value just can be provided with higherly, and in the place of southern comparative heat, this value just can be provided with lowlyer.Water temperature setting value in the present embodiment is any temperature value in 20 ℃ to 30 ℃.
Step 3: water flow switch 3 detects the discharge in the circulation lines and detected water flow signal is sent to controller; When controller receives one type of water flow signal; Continue operation circulation heating mode, when controller receives two types of water flow signals, circulation heating mode out of service; Behind the circulation heating mode out of service, get into step 4.Said controller receives one type of water flow signal and continuation operation circulation heating mode, and temperature sensor 12 continues to detect water temperatures, when controller receives one type of water temperature signal, and circulation heating mode out of service.
Wherein, one type of water flow signal is discharge water flow switch 3 detected water flow signals during more than or equal to the discharge setting value; Two types of water flow signals are discharge less than setting value, water flow switch 3 detected water flow signals when not having discharge or water flow switch 3 to break down.Said discharge setting value is that the situation such as heating capacity according to system are provided with, and heating capacity is more intense, and this value just can be provided with more greatly, and heating capacity is more weak, and this value just can be provided with smallerly.Discharge setting value in the present embodiment is made as the sixth of maximum flow of water amount in the circulation line 1.
Step 4: behind the elapsed time T, controller restarts the circulation heating mode, gets into step 3 then, when N step 3 of continuous repetition, controller circulation heating mode still out of service, turn back to step 1, otherwise turn back to step 2.
Wherein, time T is to be provided with according to concrete operating positions such as outside water supply, the stabilities of a system.Such as in the more frequent area of the situation of cutting off the water supply, water flow switch 3 is than being easier to out of order system, and this time just can be provided with short.Time T in the present embodiment is made as any time value between 1 minute to 60 minutes.The value of described N is the situation such as frequent degree that hot water interrupts to occur according to system to be provided with, and it is more frequent the situation that hot water interrupts to occur such as system, and this value can be provided with bigger.N value in the present embodiment is any integer value in 1 to 100, is preferably 3.
In the flow chart shown in Figure 2, the N value is 3.So after system got into step 4, water flow switch 3 is continuous carried out duplicate detection 3 times, system still is in circulation heating mode out of service at last, then returns the water level that detects in the water tank 10.If this moment, the water level of water tank 10 was very low, satisfied not user's water demand, system controller then starts direct heating mode, and water tank 10 is carried out the hot water filling, use for the user.
The present invention also provides a kind of hot water machine that uses the said system control method; This hot water machine is avoided causing system out of service situation such as of short duration lack of water or water flow switch 3 break down suddenly occurring; The phenomenon of hot water supply discontinuity, thereby stability, reliability and the market competitiveness thereof of raising hot water machine.
More than be merely specific embodiment of the present invention, do not limit protection scope of the present invention with this; Any replacement and the improvement on the basis of not violating the present invention's design, done all belong to protection scope of the present invention.
