Description
Technical Field

[0002] The information provided in this section is only background information related to the present disclosure, and it does not necessarily represent prior art.
[0003] Currently, the main types of household water heaters are static heating water heaters. The water inlet pipes of their water tanks are mostly elbow pipes and straight pipe types, and the water inlet pipes are fixed by positioning devices. When water is replenished from the water inlet pipe to the water tank, it flows into the water tank for replenishment. Since it directly enters the interior of the water tank, when the water inlet flow rate and water pressure are large, the cold water will violently disturb the upper layer of hot water after entering the water tank, forming a turbulent heat exchange state at the cold and hot water interface. The upper hot water is also cooled by the impact of the replenished cold water due to the large flow rate, resulting in the cold water filling the entire water tank before the hot water is drained out, leading to a low outlet water temperature and greatly reducing the hot water output rate.

[0044] As Figures 1 to 9 shown, Figure 1 and 2 in Figure A represents the height direction of the inner tank 10. A first aspect of the present invention provides a water tank assembly 100, including an inner tank 10, a water inlet pipe 12, and a buffer box 20. A water storage cavity 11 is defined inside the inner tank 10. The water inlet pipe 12 includes a first pipe section 121, and the first pipe section 121 is disposed in the water storage cavity 11. The buffer box 20 is installed in the water storage cavity 11, and along the height direction of the inner tank 10, the buffer box 20 is disposed closer to the bottom end of the water storage cavity 11 than the top end of the water storage cavity 11. A buffer cavity is defined inside the buffer box 20. The buffer box 20 is further provided with a water inlet hole 25 and at least one water outlet hole 24. The first pipe section 121 is communicated with the buffer cavity through the water inlet hole 25, and the buffer cavity is communicated with the water storage cavity 11 through at least one water outlet hole 24. The buffer cavity is used for reducing the flow rate of the liquid entering the buffer cavity from the water inlet pipe 12.
[0045] It can be understood that the water tank assembly 100 can be the water tank of an electric water heater, the water tank of a heat pump water heater, or the water tank assembly 100 of other heat source forms. The inner tank 10 can be cylindrical or other common water tank shapes. The inner tank 10 can be placed vertically or horizontally. The water inlet hole 25 is arranged at the bottom of the inner tank 10, which can be the bottom surface of the inner tank 10 or a position near the bottom end on the side surface of the inner tank 10. The water inlet pipe 12 can be a straight pipe or a bent pipe, and is specifically set according to the relative position between the buffer box 20 and the water inlet hole 25. The buffer box 20 can be cylindrical, frustum-shaped, prismatic, etc., and the flow cross-section of the buffer box 20, or the cross-section of the buffer box 20 along the radial direction of the outlet end of the water inlet pipe 12, is larger than the flow cross-section of the water inlet pipe 12. Thus, the water flowing out of the water inlet pipe 12 is decelerated in the buffer box 20 and then flows into the water storage cavity 11 from the water outlet holes 24 on the buffer box 20. One or more water outlet holes 24 can be arranged on the box body of the buffer box 20, so as to reduce the disturbance of the incoming water to the upper-layer hot water in the water storage cavity 11.
[0046] The water tank assembly 100 proposed in the first aspect of the present utility model reduces the flow rate of the liquid from the water inlet pipe 12 through the buffer cavity in the buffer box 20 by arranging the buffer box 20 at the bottom of the water storage cavity 11, and then flows out from the water outlet holes 24 on the buffer box 20, thereby reducing the disturbance of the incoming water to the upper-layer hot water in the water storage cavity 11 and improving the output efficiency of the hot water.
[0047] In some embodiments of the present utility model, the number of the water outlet holes 24 is multiple, and a part of the water outlet holes 24 are arranged on one side of the buffer box 20 facing the bottom end of the inner tank 10.
[0048] It can be understood that the water outlet holes 24 are arranged on the box body of the buffer box 20. The buffer box 20 can be cylindrical, frustum-shaped, prismatic or frustum-shaped. The water outlet holes 24 can be arranged on the peripheral wall of the buffer box 20 or at the end of the buffer box 20. One side of the buffer box 20 faces the bottom end of the inner tank 10. Arranging the water outlet holes 24 on this side can reduce the direct impact of the incoming water on the upper-layer hot water, making the position of the incoming water deviate from the upper-layer hot water, thereby reducing the phenomenon that the incoming water disturbs the upper-layer hot water and improving the hot water efficiency.
[0049] In some embodiments of the present utility model, the buffer box 20 includes a first end plate 21, a side plate 23 and a second end plate 22. The first end plate 21 and the second end plate 22 are arranged opposite to each other. The side plate 23 is annular, and opposite ends of the side plate 23 are respectively connected to the outer edge of the first end plate 21 and the outer edge of the second end plate 22. A buffer cavity is defined between the first end plate 21, the side plate 23 and the second end plate 22. The side plate 23 and / or the first end plate 21 are provided with water outlet holes 24, and the water inlet hole 25 is arranged on the second end plate 22;
[0050] Alternatively, the buffer box 20 includes a first end plate 21 and a side plate 23. The side plate 23 is annular. One axial end of the side plate 23 is connected to the first end plate 21. A buffer cavity is defined between the first end plate 21 and the side plate 23. A water outlet hole 24 is provided on the side plate 23 and / or the first end plate 21. The other axial end of the side plate 23 defines a water inlet hole 25.
[0051] It can be understood that the buffer box 20 has a cylindrical or frustum-shaped structure. The first end plate 21 and the second end plate 22 are the two ends of the buffer box 20, and the side plate 23 is the side end of the buffer box 20. The side plate 23 is cylindrical or conical. A plurality of side plates 23 can also be arranged at intervals along the circumferential direction of the buffer box 20, and a water outlet hole 24 is formed between adjacent side plates 23. The first end plate 21, the side plate 23, and the second end plate 22 enclose a cylindrical or frustum-shaped buffer cavity. The water outlet hole 24 can be provided on the first end plate 21, or water outlet holes 24 can be provided on both the first end plate 21 and the side plate 23. The water inlet hole 25 is provided on the second end plate 22 and is used to connect to the water inlet pipe 12.
[0052] In addition, one end of the buffer box 20 can be provided with an open end, that is, it does not include the second end plate 22. The buffer box 20 is composed of the first end plate 21 and the side plate 23. The side plate 23 is annularly arranged. The axial end of the side plate 23 facing away from the first end plate 21 defines a water inlet hole 25. The diameter of the water inlet hole 25 can be more than twice the diameter of the water inlet pipe 12, so that the water inlet pipe 12 can be conveniently inserted into the buffer cavity, improving manufacturability. In addition, the water inlet pipe 12 needs to be inserted to a position close to the first end plate 21 to reduce the outflow of the water from the water inlet pipe 12 through the open end.
[0053] In some embodiments of the present invention, a plurality of water outlet holes 24 are respectively provided on the side plate 23 and the first end plate 21, and the diameter of the water outlet hole 24 on the first end plate 21 is larger than the diameter of the water outlet hole 24 on the side plate 23.
[0054] It can be understood that the buffer box 20 has a cylindrical or frustum-shaped structure. A part of the water outlet holes 24 are provided at the end of the buffer box 20, that is, on the first end plate 21, and can be arranged at intervals along the circumferential direction of the buffer box 20 in one or several circles, or arranged in a rectangular array. This makes the water outlet holes 24 dispersed, and thus the water outlet is dispersed, reducing the impact on the water stored in the water storage cavity 11. A part of the water outlet holes 24 are provided on the circumferential side of the buffer box 20, that is, on the side plate 23, and can be arranged at intervals along the circumferential direction of the buffer box 20 in one circle, or arranged at intervals along the axial direction of the buffer box 20 in several circles. This makes the water outlet holes 24 dispersed in the axial and circumferential directions, and thus the water outlet is dispersed, reducing the impact on the water stored in the water storage cavity 11.
[0055] In some embodiments of the present invention, the buffer cavity has a rotating body structure, and a plurality of water outlet holes 24 on the first end plate 21 are arranged at intervals along the circumferential direction of the buffer cavity;
[0056] And / or, the buffer chamber has a rotary body structure, and a plurality of water outlet holes 24 located on the side plate 23 are arranged at intervals along the circumferential direction of the buffer chamber.
[0057] It can be understood that the buffer chamber can be cylindrical or frustum-shaped. A partial number of water outlet holes 24 are arranged on the first end plate 21 and can be distributed in a circumferential array, so that the first part of the water outlet holes 24 are evenly distributed, and further make the water flowing out after buffering more dispersed, reducing the disturbance to the hot water in the water storage chamber 11. A partial number of water outlet holes 24 are arranged on the side plate 23 and are arranged at intervals along the circumferential direction of the buffer chamber, so that the second part of the water outlet holes 24 are evenly distributed in the circumferential direction and the water outlet angle is wider, and further make the water flowing out after buffering more dispersed, reducing the disturbance to the hot water in the water storage chamber 11.
[0058] In some embodiments of the present invention, the buffer chamber has a rotary body structure, and the water inlet hole 25 is coaxially arranged with the buffer chamber.
[0059] It can be understood that the buffer chamber is a rotary body structure, such as cylindrical, frustum-shaped, conical, etc. The coaxial arrangement of the water inlet hole 25 and the buffer chamber makes the water from the first
[0060] In some embodiments of the present invention, the buffer chamber is cylindrical or frustum-shaped.
[0061] It can be understood that the buffer chamber is a rotary body structure, such as cylindrical, frustum-shaped, conical, etc., and can also be prismatic or pyramidal. This makes the buffer chamber have a good flow splitting effect, that is, the buffer chamber can split the flow in multiple directions, so that the incoming water after buffering and deceleration can enter the water storage chamber 11 from multiple directions.
[0062] In some embodiments of the present invention, both the water storage chamber 11 and the buffer chamber have a rotary body structure, and the buffer chamber is coaxially arranged with the water storage chamber 11;
[0063] And / or, the buffer chamber has a rotary body structure, and the first pipe section 121 of the water inlet pipe 12 located in the water storage chamber 11 is a straight pipe section, and the buffer chamber is coaxially arranged with the water inlet pipe 12.
[0064] It can be understood that the water storage cavity 11 is generally cylindrical, and the buffer cavity can adopt a rotating body structure, such as a cylindrical shape, a frustum shape or a conical shape, so that the water outlet holes 24 can be conveniently arranged on the peripheral wall of the buffer box 20, and then the buffered water inlet enters the water storage cavity 11 from multiple directions. The buffer cavity is coaxially arranged with the water storage cavity 11, and the buffer box 20 is located on the axis of the water storage cavity 11, making the water inlet distribution more dispersed and uniform, thereby reducing the disturbance of the water inlet to the upper layer of hot water. The first pipe section 121 of the water inlet pipe 12 located in the water storage cavity 11 is a straight pipe structure, and the first pipe section 121 is coaxially arranged with the buffer cavity, so that the water outlet of the water inlet pipe 12 can flow to the center of the buffer cavity, then decelerate through the buffer cavity, and then flow to the water storage cavity 11 through the multiple water outlet holes 24 distributed circumferentially in the buffer cavity, making the water outlet more dispersed, reducing the disturbance to the upper layer of hot water, and thus improving the hot water efficiency.
[0065] In some embodiments of the present invention, the water tank assembly 100 further includes a bracket 30, and the bracket 30 is respectively connected to the buffer box 20 and the cavity wall of the water storage cavity 11.
[0066] It can be understood that there is a certain distance between the buffer box 20 and the wall surface of the water storage cavity 11. The buffer box 20 is fixed in the water storage cavity 11 through the bracket 30. The bracket 30 can be cylindrical or L-shaped. For example, when the buffer box 20 is coaxially arranged with the water storage cavity 11, one axial end of the buffer box 20 is connected and fixed to the bottom end of the water storage cavity 11 through a cylindrical bracket 30. The buffer box 20 can be welded to the bracket 30, and the bracket 30 is then welded to the inner tank 10. When the buffer box 20 is coaxially arranged with the water inlet pipe 12, the axis of the buffer box 20 is coplanar with the radial direction of the water storage cavity 11. At this time, one axial end of the buffer box 20 can be connected and fixed to the bottom end of the water storage cavity 11 through an L-shaped bracket 30, and the bracket 30 can also be connected to the buffer box 20 and the inner tank 10 by welding.
[0067] In some embodiments of the present invention, the first pipe section 121 is spaced from the hole wall of the water inlet hole 25. The aperture of the water inlet hole 25 can be set to more than twice that of the first pipe section 121, so that the first end can be conveniently inserted into the water inlet hole 25, or the buffer box 20 can be conveniently sleeved at intervals outside the first pipe section 121, improving the manufacturability of the water tank assembly 100.
[0068] In some embodiments of the present invention, along the height direction of the inner tank 10, the hot water in the inner tank 10 is discharged through the water outlet pipe 13 arranged near its top, and a sewage discharge hole 14 is also provided at the bottom of the inner tank 10 for discharging the stored water in the inner tank 10 during maintenance.
[0069] In some embodiments of the present utility model, the cylindrical bracket 30 is 5 cm lower than the water inlet pipe 12, and the buffer box 20 is arranged with the opening facing upwards (at the folded water inlet pipe 12). The L-shaped bracket 30 is flush with the water inlet pipe 12, and the buffer box 20 faces right (opposite the water inlet of the water inlet pipe 12). The diameters of the two buffer boxes 20 are about 2-3 times that of the water inlet pipe 12. Two rows of water outlet holes 24, a total of 12 holes, are evenly opened on the side surface of the buffer box 20, and 6 water outlet holes 24 are evenly opened at the bottom. The diameter of the water outlet hole 24 is about 1 cm. After the water inlet pipe 12 is inserted, it directly faces the buffer box 20. When hot water is released for water replenishment, the buffer box 20 decelerates the replenished cold water, thereby increasing the hot water output rate.
[0070] In a second aspect of the present utility model, a water heater is proposed, which includes the water tank assembly 100 of the first aspect of the present utility model.
[0071] The water heater proposed in the second aspect of the present utility model can be an electric water heater, a heat pump water heater or a water heater of other heat source forms. The water heater has a water tank assembly 100 with a buffer box 20 arranged inside. A heating device is also provided in the water tank assembly 100. The heating device can be a heat exchanger, such as the microchannel heat exchanger of a heat pump water heater. The heat exchanger is arranged in the water tank assembly 100 and has a certain distance from the bottom of the water tank assembly 100, resulting in slower heating of the water at the bottom of the water tank assembly 100 and faster heating of the water in the upper layer. In this application, the buffer box 20 is arranged at the bottom of the water storage cavity 11 of the water tank assembly 100, so that the liquid from the water inlet pipe 12 reduces its flow rate through the buffer cavity in the buffer box 20 and then flows out from the water outlet holes 24 on the buffer box 20, thereby reducing the disturbance of the incoming water to the hot water in the upper layer of the water storage cavity 11, and thus increasing the output efficiency of the hot water.
[0072] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
