Detailed Description
In the description of the present application, the "lengthwise" orientation or positional relationship is based on the orientation or positional relationship shown in fig. 1, and it should be understood that these orientation terms are merely for convenience of description and simplicity of description, and are not indicative or implying that the apparatus or elements being referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the present application.
Referring to fig. 1 and 2, a water tank is provided in an embodiment of the present application, and includes a liner 10, a water inlet pipe 20, a water outlet pipe 30, and a heating assembly 40.
The inner container 10 is provided with a main water storage chamber 10a and a preheating chamber 10b communicating with the main water storage chamber 10a. The water inlet pipe 20 communicates with the preheating chamber 10b. The water outlet pipe 30 communicates with the main water storage chamber 10a.
The main water storage chamber 10a is a main space for storing water in the inner container 10, and the preheating chamber 10b is a space for preheating water in the inner container 10.
Inlet tube 20 is the conduit through which the water from the external source flows into preheating chamber 10b. The water outlet pipe 30 is a pipe through which water in the main water storage chamber 10a flows out of the main water storage chamber 10a.
That is, the water of the external water source flows from the water inlet pipe 20 into the preheating chamber 10b, then flows from the preheating chamber 10b into the main water storage chamber 10a, and finally flows from the water outlet pipe 30 out of the main water storage chamber 10a.
With continued reference to fig. 1, the heating assembly 40 is used to heat the main water storage chamber 10a and the preheating chamber 10b, that is, the heating assembly 40 is used to heat the water in the main water storage chamber 10a and the preheating chamber 10b.
The heating unit 40 includes at least a heat exchanger 41 provided on the outer surface of the liner 10, that is, the heating unit 40 may be provided with only the heat exchanger 41, or may be provided with other heating elements in addition to the heat exchanger 41. The heat exchanger 41 is a main heating element of the water tank, and the heat exchanger 41 mainly exchanges heat between the refrigerant and the inner container 10.
If the heating assembly 40 is provided with only the heat exchanger 41, the heat exchanger 41 may heat both the main water storage chamber 10a and the preheating chamber 10b. If the heating assembly 40 is further provided with other heating elements, the heat exchanger 41 may heat only the main water storage chamber 10a, or may heat both the main water storage chamber 10a and the preheating chamber 10b, that is, the heat exchanger 41 may heat at least the main water storage chamber 10a. While other heating elements may heat the main water storage chamber 10a, the preheating chamber 10b, and both the main water storage chamber 10a and the preheating chamber 10b, at least one other heating element may need to heat the preheating chamber 10b if the heat exchanger 41 is not used to heat the preheating chamber 10b. In summary, no matter how many heating elements are provided for the heating assembly 40, at least one heating element (including the heat exchanger 41) is required to heat the preheating chamber 10b in addition to the heat exchanger 41 being capable of heating at least the main water storage chamber 10a.
The embodiment of the application also provides a heat pump water heater, which comprises the water tank according to any embodiment of the application.
The water tank of this embodiment has set up main water storage chamber 10a and with the preheating chamber 10b of main water storage chamber 10a intercommunication in the inner bag 10, the cold water that flows into preheating chamber 10b through inlet tube 20 preheats through heating element 40 earlier, then flow into main water storage chamber 10a, because the temperature rise has become warm water after the cold water preheats, compare with cold water, the difference in temperature between original hot water in warm water and the main water storage chamber 10a is less, so, after warm water inflow main water storage chamber 10a and with the original hot water in the main water storage chamber 10a mixes, can not cause great influence to original hot water temperature, consequently, can improve the hot water output rate of water tank effectively.
In an embodiment, referring to fig. 1 and 2, a partition 10c is disposed in the liner 10 to separate the main water storage chamber 10a from the preheating chamber 10b, and the partition 10c has a plurality of micro holes 10d communicating the main water storage chamber 10a and the preheating chamber 10b.
Micropores 10d refer to pores having a relatively small pore diameter, for example, pores having a pore diameter of 1mm to 5mm (inclusive). More preferably, the pore diameter of the micropores 10d may be 2mm to 3mm (inclusive).
The water in the preheating chamber 10b flows into the main water storage chamber 10a through the micro holes 10d. The micro-holes 10d not only can reduce the flow rate of the water flowing into the main water storage chamber 10a in the preheating chamber 10b, so that the cold water can be fully preheated in the preheating chamber 10b, but also can weaken the water flowing into the main water storage chamber 10a from the micro-holes 10d into laminar flow, so as to reduce the impact on the original hot water in the main water storage chamber 10a, thereby more effectively improving the hot water output rate of the water tank.
In an embodiment, referring to fig. 1, the main water storage chamber 10a may be provided with at least a first area 10a1, the preheating chamber 10b is located at one side of the first area 10a1 along the length direction of the liner 10, and the water outlet pipe 30 is communicated with the first area 10a1.
That is, the main water storage chamber 10a may have only the first region 10a1, or other regions may be provided in addition to the first region 10a1, the first region 10a1 and the preheating chamber 10b being arranged along the longitudinal direction of the liner 10, and the hot water in the main water storage chamber 10a flowing out from the first region 10a1.
For example, referring to fig. 1, the heat exchanger 41 may surround the first region 10a1 and the outer circumferential side of the preheating chamber 10b, whereby the heat exchanger 41 may be enabled to heat both the main water storage chamber 10a and the preheating chamber 10b.
In an embodiment, referring to fig. 1 and 2, the main water storage chamber 10a may further be provided with a second area 10a2, the second area 10a2 is located on the side of the first area 10a1 where the preheating chamber 10b is provided, and the preheating chamber 10b surrounds the outer peripheral side of the second area 10a 2. That is, the preheated warm water flows into the second region 10a2 first, and then flows into the first region 10a1 from the second region 10a 2.
Referring to fig. 1 and 2, at least two water outlet holes 20a may be disposed on a side wall of the water inlet pipe 20, and a portion of the water outlet holes 20a of the water inlet pipe 20 extend into the preheating chamber 10b, wherein a portion of the water outlet holes 20a face one side of the preheating chamber 10b along the circumferential direction of the liner 10, and another portion of the water outlet holes 20a face the other side of the preheating chamber 10b along the circumferential direction of the liner 10.
Since the preheating chamber 10b surrounds the outer circumferential side of the second region 10a2, a part of the water outlet holes 20a face one side of the preheating chamber 10b in the circumferential direction of the inner container 10, and another part of the water outlet holes 20a face the other side of the preheating chamber 10b in the circumferential direction of the inner container 10, so that water can flow from the opposite sides of the water inlet pipe 20 in the circumferential direction of the inner container 10, and can flow in the circumferential direction of the inner container 10 after the water flows into the preheating chamber 10b, thereby better playing a role of reducing the flow rate of the water.
Referring to fig. 1, the second area 10a2 may be located at the lower side of the first area 10a1, that is, the water in the second area 10a2 flows upward to enter the first area 10a1, thereby also playing a role of reducing the flow rate of the water.
Referring to fig. 1 and 2, an annular partition 10c may be disposed between the preheating chamber 10b and the second region 10a2, the second region 10a2 is located at the inner side of the partition 10c, the preheating chamber 10b is located at the outer side of the partition 10c, and the micropores 10d on the partition 10c are distributed along the circumferential direction of the partition 10c, that is, the micropores 10d surround the circumferential side of the second region 10a2, so that not only the impact force of the water flow can be better dispersed, but also the disturbance to the original hot water in the main water storage chamber 10a can be further reduced, and the cold water can be heated more uniformly.
In one embodiment, referring to fig. 1, the heating element 40 may be provided with a first heating element 42, and the first heating element 42 extends into the first region 10a1.

The first heating element 42 extends into the first region 10a1 to assist in heating water in the first region 10a1.
In an embodiment, referring to fig. 1 and 2, the heating assembly 40 may further be provided with a second heating element 43, and the second heating element 43 extends into at least the preheating chamber 10b. The second heating element 43 in fig. 1 and 2 is an electric heater, and in other embodiments, the second heating element 43 may be other types of heating elements.
The second heating element 43 in fig. 1 and 2 extends into the preheating chamber 10b and the second area 10a2 at the same time, which is equivalent to that the second heating element 43 can heat the water in the preheating chamber 10b and the second area 10a2 at the same time, so that not only the cold water in the preheating chamber 10b can be heated, but also the heated warm water can be further heated after flowing into the second area 10a2, and the temperature difference between the warm water and the original hot water in the main water storage chamber 10a can be reduced better. In other embodiments, the second heating element 43 may extend into the preheating chamber 10b only, which is equivalent to the second heating element 43 heating only the water in the preheating chamber 10b.
In addition, the second heating member 43 may be used to assist in heating the preheating chamber 10b in the case of the water tank for heating the preheating chamber 10b by the heat exchanger 41, and the second heating member 43 is mainly used to heat the preheating chamber 10b in the case of the water tank for heating the preheating chamber 10b by the heat exchanger 41.
In an embodiment, referring to fig. 1, the water tank may further include a first temperature sensor 50 and a second temperature sensor 60 disposed on an outer surface of the liner 10, the first temperature sensor 50 is located outside the first area 10a1, and the second temperature sensor 60 is located outside the preheating chamber 10b. That is, the first temperature sensor 50 is used to detect the water temperature of the main water storage chamber 10a, and the second temperature sensor 60 is used to detect the water temperature of the preheating chamber 10b.
The first temperature sensor 50 and the second temperature sensor 60 are arranged, so that the temperature difference between the first area 10a1 and the preheating cavity 10b can be judged more accurately by the control assembly of the water tank, a more reasonable heating model can be selected, and the purposes of saving energy and protecting environment are achieved while the hot water output is ensured.
Taking the water tank shown in fig. 1 as an example, in a specific embodiment, taking T1 as the temperature detected by the first temperature sensor 50, T2 as the temperature detected by the second temperature sensor 60, in an initial state (i.e. the state when the heat pump water heater is started), if the difference between T1 and T2 is smaller than the first set value Ts1, i.e. T1-T2 < Ts1, and t1≡t2 is less than or equal to 15 ℃, it means that the water temperature of the main water storage cavity 10a and the preheating cavity 10b is lower and the temperature difference between the two is extremely small, at this time, the heat pump water heater can start a rapid heating mode, the first heating element 42, the second heating element 43 and the compressor of the heat pump water heater are controlled to start, the water in the preheating cavity 10b is heated by the heat exchanger 41 and the second heating element 43, and the water in the main water storage cavity 10a is heated by the heat exchanger 41 and the first heating element 42.
During the heating process, if the difference between T1 and T2 is greater than Ts1 and less than the second set value Ts2, that is, ts1 < T1-T2 < Ts2, and T1 is greater than or equal to 25 ℃, it means that the temperature difference between the main water storage chamber 10a and the preheating chamber 10b is small, and the rapid heating mode can be switched to the rapid heating mode, the first heating element 42 and the compressor remain on, and the second heating element 43 is off.

During the heating process, if the difference between T1 and T2 is greater than Ts3 and less than the fourth set value Ts4, that is, ts3 < T1-T2 < Ts4, and T1 is greater than or equal to 45 ℃, it means that the temperature difference between the main water storage chamber 10a and the preheating chamber 10b is very large, and the compressor can be switched from the normal heating mode to the energy-saving heating mode, remains on, and operates at a second frequency lower than the first frequency. Illustratively, the first frequency may be a high frequency or an intermediate frequency and the second frequency may be a low frequency.
In the heating process, if the difference between T1 and T2 is smaller than the fifth set value Ts5, that is, T1-T2 is smaller than Ts5, and T1 is equal to or higher than T2 and equal to or higher than 55 ℃, the temperature difference between the main water storage cavity 10a and the preheating cavity 10b is higher, the temperature difference between the main water storage cavity and the preheating cavity is extremely small, the energy-saving heating mode can be switched to the heat preservation mode, and the compressor is turned off, that is, the main water storage cavity 10a and the preheating cavity 10b enter the heat preservation state.
