Description
Technical Field
The utility model relates to a directly-heated heat pump water heater with a water tank.
Background
At present, a household direct-heating heat pump water heater heats water directly through a heat exchanger, the flow is controlled by an electronic water valve, water flows through the heat exchanger in the running process of the water heater, tap water is closed, a unit is stopped immediately, frequent stopping and frequent starting are possibly caused due to uncertainty in the using process, the reliability of the unit is poor, the pressure of starting and stopping is high, and pipelines are easy to damage.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems, the utility model provides a directly-heated heat pump water heater with a water tank, which effectively solves the problems pointed out in the background technology.
The technical scheme adopted by the utility model is as follows:
a directly-heated heat pump water heater with a water tank comprises the water tank and an inner disc heat exchanger arranged in the water tank, wherein a refrigerant inlet and a hot water outlet are formed in the upper portion of the water tank, a refrigerant outlet and a cold water inlet are formed in the lower portion of the water tank, two ends of a refrigerant channel of the inner disc heat exchanger are connected with the refrigerant inlet and the refrigerant outlet respectively, and two ends of a water channel are connected with the cold water inlet and the hot water outlet respectively.
Preferably, the water tank is provided with a water replenishing port.
The water replenishing port is used for replenishing water contained in the water tank, the water in the water tank has a heat storage function, and when the hot water outlet is closed, the water is used for absorbing heat generated by the inner disc heat exchanger, so that frequent start and stop of the inner disc heat exchanger are avoided.
Preferably, a temperature monitoring probe is arranged in the water tank.
The temperature monitoring probe is used for monitoring the water temperature in the water tank in real time, so that the start and stop control of the inner disc heat exchanger is facilitated.
The utility model also provides a control mode of the directly-heated heat pump water heater with the water tank, which comprises the following steps:
when the hot water outlet is opened, the inner plate heat exchanger works; when the hot water outlet is closed, the inner disc heat exchanger continues to work until the temperature monitoring probe monitors that the water temperature in the water tank reaches the set temperature, and the inner disc heat exchanger stops working.
According to the utility model, the heat exchange between the water supplementing cold water and the refrigerant and the water in the inner plate heat exchanger is realized through the inner plate heat exchanger, the heating quantity during use is increased, the hot water quantity is larger, the water in the water tank has a heat storage function, tap water is turned off, the inner plate heat exchanger can continue to work for heat storage, the problem of frequent start and stop in the use process of the existing direct-heating heat pump water heater is solved, the reliability is improved, meanwhile, the water in the inner plate heat exchanger and the water in the water tank is heated simultaneously, the water yield is increased, and the use comfort level is improved.

FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The utility model is described in further detail below with reference to specific embodiments and with reference to the attached drawings.
As shown in fig. 1, a direct-heating heat pump water heater with a water tank comprises a water tank 1, and an inner-disk heat exchanger 2 arranged in the water tank 1, the upper part of the water tank 1 is provided with a refrigerant inlet 3 and a hot water outlet 4, the lower part is provided with a refrigerant outlet 5 and a cold water inlet 6, two ends of a refrigerant channel of the inner plate heat exchanger 2 are respectively connected with a refrigerant inlet 3 and a refrigerant outlet 5, two ends of a water channel are respectively connected with a cold water inlet 6 and a hot water outlet 4, a water replenishing port 7 is arranged on the water tank 1, a temperature monitoring probe 8 is arranged in the water tank 1, when the inner disc heat exchanger 2 works, a refrigerant enters the inner disc heat exchanger 2 from the refrigerant inlet 3, leaves from the refrigerant outlet 5 after being cooled, cold water enters the inner disc heat exchanger 2 from the cold water inlet 6, leaves from the hot water outlet 4 after being heated, and the cold water and the refrigerant exchange heat in the inner disc heat exchanger 2.
The use method of the utility model comprises the following steps:
when needs use hot water, open hot water outlet 4, the work of inner heat exchanger 2, the warm water of heat accumulation in the water tank 1 and inner heat exchanger 2 heat the cold water that flows in the inner heat exchanger 2 simultaneously this moment, thereby improve the water yield, after the hot water finishes using, close hot water outlet 4, inner heat exchanger 2 continues the work this moment, the heat that inner heat exchanger 2 produced is absorbed by the water in the water tank 1, thereby make the water in the water tank 1 heat up, when temperature monitoring probe 8 monitors the temperature in the water tank 1 and reaches the settlement temperature, control inner heat exchanger 2 stop work.
Because the water in the water tank 1 has the heat storage function, when the hot water outlet 4 is opened and closed frequently to use hot water, the frequent opening and closing of the inner plate heat exchanger 2 can be avoided, and the heat pump unit is protected.
When the water for heat storage in the water tank 1 is insufficient, a proper amount of water can be added into the water tank 1 through the water replenishing port 7.
Finally, it should be noted that the above-mentioned list is only the specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the utility model.
