DETAILED DESCRIPTION

[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] Embodiment 1:

[0042] like Figures 1 to 6As shown, a water storage type electric hot water multifunctional heating furnace comprises an outer shell 1, a water storage tank 2, a water inlet pipe 3, a water outlet pipe 4, a heater 5, a heating and heating system 6, and a control system 7. Among them, the outer shell 1 serves as the support and protection of the overall structure, and is convenient for stably installing structures such as the water storage tank 2, the water inlet pipe 3, the water outlet pipe 4, the heater 5, the heating and heating system 6, and the control system 7. The water storage tank 2 is arranged in the outer shell 1; the water storage tank 2 can be one or at least two. In this embodiment, preferably, at least two of the water storage tanks 2 are arranged in the outer shell 1 and are connected to each other; specifically, there are two water storage tanks 2; and two water storage tanks 2 are installed side by side in the water storage tank 2. These connected water storage tanks 2 form a continuous water storage system, which effectively increases the water storage capacity and meets the needs of long-term use. The water inlet pipe 3 and the water outlet pipe 4 are respectively connected to the water storage tank 2 to ensure the smooth entry of water source and the effective output of hot water. Each of the water storage tanks 2 is provided with the heater 5 for heating water. In this design, each of the water storage tanks 2 is provided with an independent heater 5, which quickly heats the water body by electric heating to achieve instant supply of hot water. Preferably, the heater 5 is a heating tube, which can be coiled in the water storage tank 2 to increase the contact area with the water, so as to facilitate the rapid heating of cold water. Of course, the heater 5 can also be replaced by other types of heating elements as needed. The heating system 6 includes a pump body 61, a built-in heat exchanger 62 and a heating delivery connector 63, as well as an external pipe and a radiator; each of the water storage tanks 2 is provided with a corresponding built-in heat exchanger 62; the pump body 61, at least two built-in heat exchangers 62 and the heating delivery connector 63 are connected in sequence; a closed-loop heating water circulation system is formed by setting the pump body 61, the built-in heat exchanger 62, the heating delivery connector 63, the external pipe and the radiator to effectively supply heat to the external environment. At the same time, it is preferred to set a built-in heat exchanger 62 in each water storage tank 2. By designing the built-in heat exchanger 62 and combining multiple built-in heat exchangers 62, the heat of the hot water in the water storage tank 2 can be transferred more quickly, so as to achieve the purpose of rapid heating and high efficiency of heating and heat exchange. The control system 7 is electrically connected to the heater 5 and the pump body 61 respectively.

[0043] The water storage type electric hot water multifunctional heating furnace is integrated into an outer shell 1, a water storage tank 2, a water inlet pipe 3, a water outlet pipe 4, a heater 5, a heating and heat supply system 6 and a control system 7. The control system 7 is first used to control the heater 5 and the pump body 61, and the water storage tank 2 is used to store water and is heated by the heater 5 to stably supply domestic hot water. Then, the pump body 61, the built-in heat exchanger 62 and the heating delivery joint 63 are used to form a part of the heating and heat supply system 6, water is passed to the heating and heat supply system 6, and the built-in heat exchanger 62 is used to perform heating and heat exchange in the water storage tank 2, and then heat is supplied to the external environment to change the temperature of the external environment, thereby realizing rapid heating of hot water and precise control of heating, so that the water storage type electric hot water multifunctional heating integrates the functions of water storage, electric heating and heating, realizes the switching of hot water supply and heating mode, improves the convenience of use, reduces the space occupied by the equipment, reduces the installation and maintenance costs, and is used in various places such as homes, small offices, shops, etc. to meet the diverse needs of different users.

[0044] In this embodiment, the water storage type electric hot water multifunctional heating furnace further includes a manual operation panel 8, a display screen 9, a temperature sensor 50, a water flow sensor and a pressure gauge; the manual operation panel 8 and the display screen 9 are arranged on the outer shell 1 and are electrically connected to the control system 7 respectively. The manual operation panel 8 is a mechanical manual adjustment panel structure, on which there are adjustment knobs for the power or the heated temperature of the heater 5, the speed adjustment knobs or buttons of the pump body 61, a power switch, and the same number of seesaw switches as the heater 5 and correspondingly controlling the power supply of each heater 5. The user can manually adjust the parameters such as the power or the heated temperature of the heater 5 and the speed of the pump body 61 through the manual operation panel 8, and the display screen 9 can display the temperature of the water storage tank 2, the power of the heater 5, the speed of the pump body 61 and other data. The user can also reasonably open the corresponding number of seesaw switches according to the needs, so that the corresponding heater 5 can work, meet the personalized needs of hot water supply and heating, and save power. The heating system 6 also includes a water outlet joint 30 connected to the pump body 61; the water storage tank 2, the heating delivery joint 63, and the water outlet joint are all connected with a temperature sensor 50 for measuring the water temperature, and the temperature sensor 50 is electrically connected to the control system 7; the pressure gauge and the water flow sensor for detecting the water flow of the pump body 61 are connected to the pipeline connected between the pump body 61 and the built-in heat exchanger 62, and the pressure gauge can feedback the fluid pressure of the heating system 6 in real time, which is convenient for adjusting the pressure of the heating system 6. By setting the temperature sensor 50, the water temperature flowing into and out of the built-in heat exchanger 62 and the water temperature in the water storage tank can be detected and displayed on the display screen 9. Of course, according to needs, temperature sensors can also be set at other pipeline positions of the heating system 6, so that the temperature at each structural position can be detected in real time to facilitate temperature control and adjustment. For the temperature sensor 50, it can be an NTC temperature probe.

[0045] In this embodiment, the water outlet joint is connected with an expansion tank assembly 40; the water outlet joint 30 is connected with an expansion tank assembly 40; specifically, the expansion tank assembly 40 includes a water connection joint 401, an exhaust valve 402, a water pipeline 403 and an expansion tank 404; the water pipeline 403 is respectively connected with the water structure, the water outlet joint 30 and the expansion tank 404; the water pipeline 403 is connected with the exhaust valve 402 close to the water connection joint 401. The expansion tank assembly 40 is formed by arranging the water connection joint 401, the exhaust valve 402, the water pipeline 403 and the expansion tank 404. When pressurized water from the outside enters the air bag of the expansion tank 404, the nitrogen sealed in the expansion tank 404 is compressed. According to Boyle's gas law, the volume of the gas decreases and the pressure increases after being compressed, until the gas pressure in the expansion tank 404 reaches the same as the water pressure, and the water stops entering. When the water loss pressure decreases, the gas pressure in the expansion tank 404 is greater than the water pressure. At this time, the gas expansion squeezes the water in the airbag into the heating system 6, which can buffer and stabilize the pressure fluctuations of the heating system 6 and prevent the pressure from being too high or too low, ensuring that the heating system 6 operates under a relatively stable pressure to achieve a good heating effect.

[0046] In this embodiment, the built-in heat exchanger 62 is a built-in heat exchange coil; the built-in heat exchange coil is provided with a spiral protrusion strip 6214 that is spirally extended from one end to the other end and is concavely arranged; the tube wall of the built-in heat exchange coil and the spiral protrusion strip 6214 form a spiral flow channel. By providing a concave spiral groove 624 in the length direction of the built-in heat exchange coil, the surface area inside the tube can be increased, thereby improving the heat exchange efficiency; at the same time, the design of the spiral groove 624 can form a spiral flow channel in the pipeline of the built-in heat exchange coil, so that the fluid will move along the spiral path when flowing in the tube. Such a design can increase the residence time of the fluid in the built-in heat exchange coil and improve the effect of heat exchange. Of course, according to needs, the built-in heat exchanger 62 can also use other heat exchange structures to replace the built-in heat exchange coil.

[0047] Preferably, the built-in heat exchange coil includes a first direct current pipe section 621, a second direct current pipe section 622 and a spring-shaped pipe section 623; the first direct current pipe section 621, the spring-shaped pipe section 623 and the second direct current pipe section 622 are sequentially connected. The built-in heat exchange coil is formed by arranging the first direct current pipe section 621, the spring-shaped pipe section 623 and the second direct current pipe section 622, and the spring-shaped pipe section 623 is spirally arranged to form an existing spring-shaped structure, extending the length in the water storage tank 2, thereby extending the overall length of the built-in heat exchange coil in the water storage tank 2, so as to better heat exchange and heating, and can transport more heat.

[0048] In order to connect the built-in heat exchangers 62 in series, further extend the water flow path in the built-in heat exchanger 62, better improve the heat exchange efficiency, and output more heat for heating, two adjacent built-in heat exchangers 62 are connected by a U-shaped heat exchange tube 20.

[0049] In this embodiment, the outer shell includes an upper maintenance cover 11, an upper end cover 12, an inner lining foam 13, an upper shell 14, an inner support bottom cover 15 and a lower shell 16; the upper maintenance cover 11, the upper end cover 12, and the inner lining foam 13 are sequentially adapted and installed on the upper end of the upper shell 14 from top to bottom; the inner support bottom cover 15 is adapted and installed in the upper end of the lower shell 16; the lower end of the upper shell 14 is connected to the upper end of the upper shell 14; the lower end of the water storage liner 2 is installed on the inner support bottom cover 15; the upper end of the water storage liner 2 extends into the upper shell 14. The control system 7, the manual operation panel 8 and the display screen 9 are installed in the lower shell 16. By setting the outer shell in this way, the positions of the structures such as the water storage liner 2, the control system 7, the manual operation panel 8 and the display screen 9 are reasonably distributed, and the functions of water storage, electric heating and heating are integrated.

[0050] In addition, in this embodiment, the heater 5 is a heating tube; the lower end of the heating tube is mounted on the bottom end of the water storage tank 2; the bottom end of the water storage tank 2 is provided with a sealing rubber ring 60 for sealing the gap between the heating tube and the water storage tank 2, and a heat insulation cover 70 for covering the heater 5. The sealing rubber ring 60 provides a good water sealing effect, and the heat insulation cover 70 covers the lower end of the heater 5 to protect the structure in the lower shell 16.

[0051] It should be noted that the manual operation panel 8, display screen 9, temperature sensor 50, water flow sensor and pressure gauge are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The specific implementation of this application may involve the use of software, but the software used is the most commonly used software by technical personnel in this field, and is not within the scope of protection of the claims of this patent application.

[0052] The working principle of the present invention is:

[0053] First, the user operates the manual operation panel 8 to adjust the power of the heater 5, the speed of the pump 61 and other parameters, and sets the corresponding parameters, and the display screen 9 displays the set parameter data;

[0054] Secondly, when in use, the control system 7 is started by operating the manual operation panel 8, and the heater 5, the pump body 61 and the corresponding sensors are controlled by the control system 7, and the cold water in each water storage tank 2 is heated into hot water by each heater 5;

[0055] Then the user can select the hot water mode or the heating mode or both modes. When the hot water mode is selected, hot water flows out of the water outlet pipe 4 and can be used as domestic hot water.

[0056] When the heating mode is selected, the pump body 61 works, and the pump body 61, the built-in heat exchanger 62, the heating delivery connector 63, the external pipe and the radiator form a closed-loop heating water circulation system, which effectively supplies heat to the external environment, such as home heating, and realizes rapid heating of hot water and precise control of heating.
