The water outlet end of the instant heating body 15 is connected with the water outlet of the water purifier;
a flow meter 16 is also arranged between the flow control pump 12 and the water inlet end of the instant heating body 15;
the controller is electrically connected to the instant heating element 15 and the phase change auxiliary heating element 142, respectively, and is used for controlling one of the instant heating element 15 and the phase change auxiliary heating element 142 to be in a working state and the other to be in a non-working state.
In one embodiment, as shown in fig. 2, the phase change auxiliary heating body includes: a housing 1421, a water pipe 1422 inside the housing, a heater 1423, a temperature monitor 1424, and a phase change material 1425 filled inside the housing; the phase change of the phase change material 1425 may absorb or release heat, the heating body 1423 generates heat when working, so that the phase change material 1425 gradually heats up to a phase change temperature point, so that the phase change material 1425 absorbs the heat generated by the heating body 1423 to store energy, and after the purified water at the normal temperature enters the water pipeline 1422, the phase change material 1425 performs phase change to release heat, so as to preheat the purified water in the water pipeline 1422.
Further, the controller is electrically connected to the instant heating element 15 and the heating element 1423 of the phase change auxiliary heating element 142, respectively, and is configured to control one of the instant heating element 15 and the heating element 1423 of the phase change auxiliary heating element 142 to be in an operating state, and the other to be in a non-operating state.
In one implementation manner, as shown in fig. 1, the water outlet end of the flow control pump 12 is respectively connected with one end of the first electromagnetic valve 131 and one end of the second electromagnetic valve 141;
the other end of the first electromagnetic valve 131 is connected with the water inlet end of the flowmeter 16;
the other end of the second electromagnetic valve 141 is connected with the water inlet end of the water pipeline 1422 in the phase change auxiliary heating body 142;
the water outlet end of the water pipeline 1422 in the phase change auxiliary heating body 142 is connected with the water inlet end of the flowmeter 16 through the one-way check valve 143;
the water outlet end of the flowmeter 16 is connected with the water outlet of the water purifier through the instant heating body 15;
the waste water outlet of the filtering system 11 is connected with the waste water outlet of the water purifier through a concentrated water electromagnetic valve 19;
a user accesses raw water into a water purifier, two paths of purified water after being filtered are pumped by a flow control pump 12 after passing through a filtering system 11, one path of purified water passes through a first electromagnetic valve 131 and then enters a water inlet end of an instant heating body 15 through a flow meter 16, and then the purified water passes through a water outlet end of the instant heating body 15 and is used by the user; the other path is connected to the phase change auxiliary heating body 142 through the second electromagnetic valve 141, is connected to the flowmeter 16 through the one-way check valve 143, enters the water inlet end of the instant heating body 15, and then the purified water passes through the water outlet end of the instant heating body 15 for users to use.
Because the phase-change auxiliary heating body 142 comprising the phase-change material 1425 is arranged on the water path at the front end of the instant heating body 15, the water temperature at the water inlet end of the thick-film instant heating body 15 is increased by heat storage of the phase-change material 1425, so that the heating speed of the thick-film instant heating body 15 can be increased, and the hot water outlet flow rate at the water outlet end of the thick-film instant heating body 15 is increased.
In order to increase the contact area between the phase change material 1425 and the water pipe 1422, the water pipe 1422 may be wound inside the housing 1421.
The phase change material 1425 has a phase change temperature point (T) less than 100 ℃ and greater than 25 ℃, i.e., T < 100 ℃ at 25 ℃, where there is a transition between solid and liquid phases, releasing or absorbing a large amount of heat during the transition.
Specifically, when the phase change material 1425 absorbs heat generated by the heating body 1423 for energy storage, the phase change material 1425 is gradually converted from a solid phase to a liquid phase; when the phase change material 1425 undergoes a phase change to release heat, the phase change material 1425 gradually changes from a liquid phase to a solid phase.
When in use, a user firstly puts the water purifier on the power supply and the raw water.
When the instant heating element 15 is not switched on to work, the heating element 1423 in the phase change auxiliary heating element 142 is controlled to work; when detecting that the temperature of the heating body 1423 is increased to a first preset temperature as monitored by the temperature monitor 1424, controlling the heating body 1423 to stop heating; when it is detected that the temperature monitor 1424 monitors that the temperature of the heating body 1423 decreases from the first preset temperature to the second temperature, the heating body 1423 is controlled to start operating.
Specifically, when the instant heating element 15 is not turned on to work, the control board main chip MCU drives the heating element 1423 in the phase change auxiliary heating element 142 to start to work, the heat generated by the work is transferred to the phase change material 1425 to heat up, and when the temperature is raised to T + Δ T1 (a first preset temperature) (for example, Δ T1 is greater than or equal to 0.5 ℃ and less than or equal to 10 ℃), the heating element 1423 stops heating; when the temperature falls to T- Δ T2 (second preset temperature) (e.g., 0.5 ℃. DELTA.T 1. ltoreq.5 ℃), heating is restarted, and the cycle is repeated so that phase change heating body 1423 is kept warm at phase change temperature point T.
When detecting that a start instruction is received, controlling the heater 1423 to stop working; the start instruction instructs to turn on the instant heating body 15; after the heating body 1423 stops operating for a preset time period, the instant heating body 15 is turned on.
Specifically, when the instant heating element 15 is turned on to operate, the control board main chip MCU drives the phase change heating element to stop operating in advance before Δ t time (preset duration) (for example, Δ t is greater than or equal to 0.2s and less than or equal to 10s) before the instant heating element 15 is turned on to operate, so as to ensure that the instant heating element 15 and the heating element 1423 in the phase change auxiliary heating element 142 do not operate simultaneously, thereby avoiding the occurrence of a situation where the total power exceeds the set rated power of the product.
Through this scheme, can be under the prerequisite that keeps water purifier total power not super ampere of rule 2200W, make full use of machine idle time carries out the energy storage, preheats water at next water use in-process to can promote hot water rate of heating, promote the play water velocity of flow.
When a first water taking instruction is detected and received, the flow control pump 12 is controlled to operate, the first electromagnetic valve 131 is opened, and the second electromagnetic valve 141 is closed; the first water get instruction indicates that the user-set water get temperature is below the phase change temperature point of the phase change material 1425.
Specifically, the control method for taking the drinking water with the phase transition temperature point T below by the user comprises the following steps:
when a user sets to take normal-temperature water or warm water with the temperature lower than T, the control panel main chip MCU drives the flow control pump 12 to operate, the first electromagnetic valve 131 is opened, and the second electromagnetic valve 141 is closed, so that the purified water sequentially passes through the first electromagnetic valve 131 and the flowmeter 16 and then enters the instant heating body 15.
When a second water taking instruction is detected and received, the flow control pump 12 is controlled to operate, the first electromagnetic valve 131 is closed, and the second electromagnetic valve 141 is opened; the second water fetch instruction indicates that the user-set water fetch temperature is above the phase change temperature point of the phase change material 1425.
Specifically, the control method for taking the drinking water with the phase-change temperature point T above comprises the following steps:
when a user sets to take hot water with the temperature higher than T, the control panel main chip MCU drives the flow control pump 12 to operate, the second electromagnetic valve 141 is opened, and the first electromagnetic valve 131 is closed, so that the purified water sequentially passes through the second electromagnetic valve 141, the phase change auxiliary heating body 142, the one-way check valve 143, and the flow meter 16 and then enters the instant heating body 15.
