Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and more specifically to a water heater that can dispense water at a fixed quantity and temperature. Background Technology

[0002] With the continuous improvement of living standards, water dispensers have become an essential household appliance for thousands of families. However, traditional water dispensers mostly supply cold water directly without boiling it, which poses certain safety hazards.

[0003] To improve drinking safety, some water dispensers on the market use a method of boiling water first and then cooling it. For example, Chinese patent CN222815642U discloses a wind-cooled rapid cooling structure. The heating element boils the water in the reservoir, and then a water pump and a heat dissipation component cool the water back into the reservoir, bringing it to a set temperature. The water is then dispensed at the appropriate temperature through the spout for convenient drinking. While this existing technology can heat liquid to a boiling point and then cool it to a set temperature, its cooling function is achieved by cooling all the water in the reservoir, resulting in long cooling times and low cooling efficiency. Utility Model Content

[0014] In a preferred embodiment, an air inlet shroud is provided between the fan and the air inlet.

[0015] This air intake shroud can effectively protect equipment such as radiators and fans while ensuring airflow, thereby guaranteeing the normal operation of the radiator and meeting its heat dissipation needs.

[0016] In a preferred embodiment, there are multiple air inlets distributed within a circular area on one side of the fuselage; and multiple air outlets distributed within a rectangular area on the other side of the fuselage.

[0017] In this technology, the water heater is equipped with multiple air inlets and multiple air outlets, which respectively form air intake and air outlet areas that cooperate with the fan and radiator, thereby improving the ventilation and heat dissipation effect.

[0018] In a preferred embodiment, a control panel assembly is provided at the front of the unit, the control panel assembly including a controller; the water outlet is located below the control panel assembly for convenient user operation and water dispensing.

[0019] In a preferred embodiment, the inner cavity of the unit is also equipped with a power board, which is used to connect an external power source to supply power to the water heater.

[0020] In a preferred embodiment, the radiator is an aluminum radiator plate. Using an aluminum radiator plate in this technology offers advantages such as high space utilization and strong cold storage capacity.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] Reference Figure 1-8 This invention describes a water heater capable of dispensing water at a fixed quantity and temperature according to an embodiment of the present invention.

[0038] In one embodiment, such as Figure 1-2 As shown, a water heater capable of dispensing water at a fixed quantity and temperature includes a kettle 1, a water collection tank 2, a cooling mechanism 3, and a controller.

[0039] The bottom of the kettle 1 is equipped with a first temperature sensor 11 and a heating element 12. The bottom of the water tank 2 is equipped with a second temperature sensor 21 and the inner cavity is equipped with a liquid level sensor 22. The kettle 1 is connected to the water tank 2 through a first water pump 4.

[0040] The circulating water outlet of the water collection tank 2 is connected to one end of the cooling mechanism 3 through the second water pump 5, and the other end of the cooling mechanism 3 is connected to the circulating water return outlet of the water collection tank 2. The water collection tank 2 is also connected to the water outlet 7 of the water heater through the metering pump 6.

[0041] The controller is connected to the first temperature sensor 11, the heating element 12, the second temperature sensor 21, the liquid level sensor 22, the cooling mechanism 3, the first water pump 4, the second water pump 5, and the metering pump 6.

[0042] The heating element 12 can be a heating wire or a heating plate, which is attached to the bottom of the kettle 1 to heat the water in the kettle 1; the first temperature sensor 11 is used to detect the water temperature in the kettle 1. When the first temperature sensor 11 detects that the water in the kettle 1 has reached the boiling point temperature, the heating element 12 stops heating; the second temperature sensor 21 is used to detect the water temperature in the water collection tank 2. When the water in the water collection tank 2 is detected to have reached the preset temperature, the second water pump 5 and the cooling mechanism 3 can be controlled to stop working and no longer cool.

[0043] In practice, the kettle 1 is filled with water. The heating element 12 first boils the water in the kettle 1 to boiling point. The first temperature sensor 11 trips, and the controller controls the heating element 12 to stop working. The water heater draws hot water from the kettle 1 through the first water pump 4 and injects it into the water collection tank 2. When the level sensor 22 senses that the water level in the water collection tank 2 has reached the threshold, it notifies the controller to turn off the first water pump 4 and stop water injection. Then, the second water pump 5 transports the hot water from the water collection tank 2 to the cooling mechanism 3 for cooling. The cooled water returns to the water collection tank 2, repeating the water circulation for cooling. When the second temperature sensor 21 detects that the water temperature in the water collection tank 2 has reached the preset temperature, the controller controls the metering pump 6 to output the preset capacity and preset temperature of water to the water outlet 7. The required capacity and water temperature are set by the user, with a preset capacity range of 100ml-300ml and a temperature range of 45℃-75℃. Since the water temperature after cooling is below 83℃, the metering pump 6 can accurately control the water output and will not become inaccurate due to high temperature.

[0044] The water heater with quantitative and temperature-controlled water output provided in the above embodiments utilizes a kettle 1, a water collection tank 2, a liquid level sensor 22, a first water pump 4, a second water pump 5, and a metering pump 6 to control water volume separation cooling, achieving a fully automatic cooling effect. Finally, the metering pump 6 controls the water output, directly discharging quantitative and temperature-controlled cooling water from the outlet 7. This shortens cooling time, improves cooling efficiency, and precisely controls the water output and temperature. In actual use, users can select the temperature and capacity with a single button, providing a good user experience.

[0045] In this embodiment, as Figure 3-5 As shown, the cooling mechanism 3 includes a radiator 31 and a fan 32 located on the side of the radiator 31; one end of the radiator 31 is connected to the circulation outlet of the water collection tank 2 via a second water pump 5, and the other end of the radiator 31 is connected to the circulation return outlet of the water collection tank 2; the controller is connected to the fan 32.

[0046] The radiator 31 can be an aluminum heat sink or other types of heat dissipation pipes, such as copper pipes.

[0047] The cooling mechanism 3 in the above embodiment adopts an air-cooled structure, which is low in cost and stable in performance, and does not require frequent maintenance.

[0048] In specific implementation, the water flow direction between the water collection tank 2 and the radiator 31, the first water pump 4, the second water pump 5, and the metering pump 6 is as follows: Figure 6-8 As shown by the middle arrow: First, the inlet of the first water pump 4 draws hot water from the kettle 1 through a pipe; the outlet of the first water pump 4 delivers the hot water to the inlet of the water collection tank 2 through a pipe. The water collection tank 2 is equipped with a level sensor 22. When the amount of hot water in the water collection tank 2 reaches the threshold, the controller controls the first water pump 4 to stop working and automatically stops injecting hot water; the inlet of the second water pump 4 draws water from the circulation outlet of the water collection tank 2 through a pipe, and the outlet of the second water pump 4 delivers the hot water to one end of the radiator 31 through a pipe, and then injects it back into the water collection tank 2 from the other end of the radiator 31 through a pipe; the inlet of the metering pump 6 draws the water volume set by the user from the bottom of the water collection tank 2, and the outlet of the metering pump 6 delivers the water to the spout 7.

[0049] In this embodiment, the kettle 1 is mounted on the body 8 of the water heater, and the water collection tank 2, radiator 31, fan 32, first water pump 4, second water pump 5 and metering pump 6 are all mounted inside the body 8.

[0050] An air inlet 81 is provided on one side of the chassis 8, and an air outlet 82 is provided on the other side; the heat sink 31 is located near the air outlet 82, and the fan 32 is located near the air inlet 81.

[0051] Specifically, after the fan 32 is started, it draws in air from the air inlet 81 on one side of the chassis 8. The airflow carries away the heat from the heat sink 31 and blows it out through the air outlet 82 on the other side of the chassis 8, achieving the effect of cold air in and hot air out, ensuring the cooling effect.

[0052] In this embodiment, an air inlet shroud 33 is provided between the fan 32 and the air inlet 81.

[0053] In practice, when the fan 32 rotates, cold air enters from one side of the body 8 through the air inlet 81, passes through the air inlet shroud 33 to the fan 32, and the fan 32 blows the cold air toward the radiator 31; when hot water flows through the radiator 31, the cold air absorbs the heat of the hot water to form hot air and then flows out through the air outlet 82, thus achieving air cooling.

[0054] The aforementioned air intake cover can effectively protect the radiator 31 and fan 32 while ensuring air circulation, thereby guaranteeing the normal operation of the radiator 31 and meeting its heat dissipation requirements.

[0055] In this embodiment, there are multiple air inlets 81, which are distributed in a circular area on one side of the body 8 and are similar in shape to the fan 32, so as to facilitate the intake of air and the formation of airflow; there are multiple air outlets 82, which are distributed in a rectangular area on the other side of the body 8 and are similar in shape to the heat sink 31, so as to facilitate the passage of airflow after heat absorption and ensure the cooling effect.

[0056] In this embodiment, a control panel component 9 is provided at the front end of the body 8. The control panel component 9 includes a controller. The water outlet 7 is located below the control panel component 9 for convenient operation and water dispensing by the user.

[0057] The control panel component 9 may include a controller and a control panel. The control panel is connected to the controller and may be an LCD touch panel or a button control panel with a display screen. In specific implementation, the control panel can be used to receive user control commands, such as setting precise water output and water temperature. The water outlet 7 is located below the control panel component 9, so that the user can directly take water after operation, making it more convenient to use.

[0058] In this embodiment, the inner cavity of the body 8 is also provided with a power board 91, which is used to connect an external power source to supply power to the water heater.

[0059] In practice, the power board 91 can be connected to the water heater's controller, heating element 12, fan 32, first water pump 4, second water pump 5, metering pump 6 and other components to provide power.

[0060] In this embodiment, the radiator 31 is an aluminum heat sink plate, which has the advantages of high space utilization and strong cold storage capacity.

[0061] In this embodiment, the top of the kettle 1 is provided with a kettle lid assembly 13, which is used to seal the kettle opening and prevent water vapor from overflowing upwards during heating, thus preventing safety hazards. The bottom of the kettle 1 is provided with a kettle base 14, which is located between the kettle 1 and the body 8 and is used to assemble the kettle. The structure is simple and the installation is convenient.

[0062] In practice, the kettle 1 can be detachably mounted on the kettle base 14, making it convenient to install and remove the kettle 1 for cleaning.

[0063] In this embodiment, a base 10 is provided at the bottom of the body 8. The base 10 is used to mount the body 8 so as to place and move the water heater.

[0064] In practice, the bottom of the base 10 can also be equipped with multiple foot pads to make the water heater more stable when placed on a horizontal surface.
