Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to an air source water heater. Background Technology

[0002] Air source heat pump water heaters are widely used in residential and commercial hot water supply due to their high efficiency and energy saving. Their core components typically include a heat pump unit and a hot water storage tank. The water inlet design of the storage tank is generally as follows: cold water is introduced through a tap water inlet at the bottom of the tank, and the heated hot water is forced out from the hot water outlet at the top of the tank by the pressure provided by the municipal tap water supply or a booster pump, supplying the hot water to the user terminals (such as showers, faucets, etc.). Chinese patent CN208952414U discloses an energy-saving water tank for an air source heat pump water heater used in kitchens and bathrooms. This design utilizes the characteristic that "hot water has a low density and naturally resides at the top of the tank," combined with the inlet water pressure, to achieve a "top-out hot water" supply mode.

[0003] However, this design, which relies on external water pressure to drive hot water output, has a significant inherent flaw: when the external tap water supply is interrupted (such as municipal water outages, pipeline repairs, water source failures, etc.), the pressure at the inlet drops sharply or even disappears. At this time, although there may still be a large amount of heated warm water inside the hot water storage tank (located in the top area of ​​the tank), due to the loss of the bottom inlet pressure, an effective outlet pressure cannot be formed at the top of the tank, resulting in hot water not being able to be expelled normally or flowing out extremely slowly. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an emergency heating system with a dual-outlet structure and a float-type water intake device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an air source water heater, characterized in that it includes a water tank;

[0006] The water inlet, located at the bottom of the water tank, is used to replenish the water tank with cold water and provide pressure.

[0007] The first outlet, located at the top of the water tank, uses water pressure from the inlet to discharge hot water from the top to supply water to external equipment; and

[0008] The second outlet, located below the first outlet, is used to supply water to external equipment after the pressure at the inlet disappears.

[0009] In the above scheme, preferably, a controller is included, and a flow meter is provided on the water inlet, and the flow meter is connected to the controller;

[0010] The second outlet is equipped with an electrically controlled valve, which is coupled to a flow meter via a controller.

[0011] In the above scheme, preferably, a float ball is provided in the water tank, the float ball is connected to the second water outlet through a flexible tube, and the float ball is provided with several water inlet holes that communicate with the flexible tube.

[0012] In the above scheme, preferably, the float is a hollow sphere, and the surface of the float is uniformly provided with a plurality of water inlet holes that communicate with the internal cavity of the float.

[0013] In the above scheme, preferably, the float is provided with a connection port, one end of the flexible tube is connected to the connection port, and the other end is connected to the second water outlet.

[0014] In the above scheme, preferably, a counterweight is provided on the connection port, so that the float is always in contact with the warm water at the top after being placed in the water tank.

[0015] In the above scheme, preferably, the float is made of engineering plastic.

[0016] In the above scheme, preferably, the height distance between the second water outlet and the first water outlet is 1 / 4 to 2 / 3 of the overall height of the water tank.

[0017] In the above scheme, preferably, the first water outlet and the second water outlet are connected to the main pipe, and the electric control valve is located between the main pipe and the second water outlet.

[0018] In the above scheme, preferably, the counterweight is made of stainless steel.

[0019] The beneficial effects of this utility model are: through the second water outlet and float system, the stored hot water can be removed under zero water pressure conditions;

[0020] In addition, the combination of the float and the counterweight ensures that the float only draws in the hot water at the top, thereby preventing excessive changes in the water temperature at the main pipe.

[0021] This invention improves the emergency handling capability of water tanks in the event of water shortage, significantly improves the efficiency of water tank use, and enhances user comfort. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-2 .

[0025] An air source heat pump water heater includes a water tank 1, an inlet 2 at the bottom of the water tank 1, and a first outlet 3 at the top of the water tank 1. The water tank 1 discharges warm water from the top of the water tank through the water pressure from the bottom inlet 2, so that the water temperature discharged from the first outlet 3 is always the higher part of the water temperature in the water tank 1, thereby providing warm water to external devices.

[0026] The water tank 1 is provided with a second water outlet 4, which is located below the first water outlet 3. The longitudinal height distance between the second water outlet 4 and the first water outlet 3 is 1 / 4 to 2 / 3 of the overall height of the water tank 1. The second water outlet 4 can supply water to external equipment after the pressure at the water inlet 2 disappears.

[0027] Both the first outlet 3 and the second outlet 4 are connected to the main pipe 5. The hot water discharged from the first outlet 3 or the second outlet 4 provides warm water to external equipment through the main pipe 5. An electric control valve 401 is installed between the second outlet 4 and the main pipe 5. The electric control valve 401 is used to control the opening and closing of the connection between the second outlet 4 and the main pipe 5. Specifically, the air source water heater also includes a controller. The electric control valve 401 is connected to the controller. A flow meter 201 is installed on the inlet 2. The flow meter 201 is used to monitor the flow rate and pressure of the water entering the inlet 2. The flow meter 201 is connected to the controller. When the flow rate and pressure at the inlet 2 decrease significantly, the controller receives feedback and controls the electric control valve 401 to open, so that the second outlet 4 is connected to the main pipe 5, and the water in the water tank 1 is supplied to the main pipe 5 through the second outlet 4.

[0028] The water tank 1 is equipped with a float 101 made of engineering plastic to improve its durability and corrosion resistance. The float 101 is a hollow sphere with a wall of uniform thickness on the outside. The float 101 is connected to the second water outlet 4 through a flexible tube 102. The surface of the float 101 is evenly provided with multiple water inlet holes 103 that communicate with the internal cavity of the float 101. When the float 101 is placed in the water tank 1, the float 101 is always located at the water surface of the water tank 1. The lower end of the float 101 is provided with a connection port 104. A counterweight 105 is fixed to the outer edge of the connection port 104. With the above configuration, when the float 101 floats on the water surface of the water tank 1, at least 1 / 2 of the float 101 can be placed in the water. At this time, water flows into the interior of the float 101 through several water inlet holes 103.

[0029] One end of the flexible tube 102 is connected to the connection port 104, and the other end is connected to the second outlet 4. The water flowing into the float 101 flows through the flexible tube 102 to the second outlet 4, so that the part of the water in the upper part of the water tank 1 that is always at a higher temperature flows into the second outlet 4 in advance.

[0030] The counterweight 105 is made of stainless steel, thereby improving its corrosion resistance and rust resistance in the water tank 1.

[0031] Using an air source water heater as described above:

[0032] During normal use, cold water is always supplied through the inlet 2 of the water tank 1, while the warm water at the top of the water tank 1 is discharged through the first outlet 3 after being subjected to the inlet pressure at the bottom, thus supplying water to external equipment.

[0033] When the pressure inside the water tank is abnormal or there is no pressure, that is, when the water pressure and flow rate at the inlet 2 drop rapidly, the flow meter 201 controls the electric control valve 401 to open it through the controller, thereby connecting the second outlet 4 to the main pipe 5. At this time, the warm water at the top of the water tank 1 enters the float 101 through the inlet hole 103, flows to the second outlet 4 through the flexible pipe 102, and is discharged to the external equipment through the main pipe 5 to supply water to the external equipment.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
