Abstract
Description
Technical Field
[0001] This utility model relates to the field of water heaters, and in particular to a novel water heater. Background Technology
[0002] Most water heaters on the market today use a single-cavity design, integrating water heating and storage functions into the same space. During use, when the user turns the water heater off and then on again, the residual hot water in the cavity lacks an independent heat exchange cooling device and cannot dissipate heat and cool down in time. If the user turns the switch back on shortly afterward, the residual hot water may not have completely cooled down and will rapidly heat up under the continuous heating of the heating element, resulting in the initial water temperature being much higher than the set temperature. This could potentially cause scalding and pose a significant safety hazard. Utility Model Content
[0003] In order to overcome at least one of the defects described in the prior art, the present invention provides a novel water heater that can effectively reduce the water temperature after the water heater is restarted, reduce the probability of scalding for users, and improve safety during use.
[0004] The technical solution adopted by this utility model to solve its problem is:
[0005] A new type of water heater includes:
[0006] A water heater body, wherein the water heater body is provided with a heating element, the heating element being used for heating;
[0007] A water tank having a water storage cavity, a heat-conducting plate being provided inside the water storage cavity, the heat-conducting plate dividing the water storage cavity into a first cavity section and a second cavity section, the first cavity section having a first water inlet and a first water outlet, the first water inlet being used to guide water flow into the first cavity section.
[0008] The second cavity has a second inlet and a second outlet. The second inlet is connected to the first outlet, and the second outlet is used to guide the water flow out.
[0009] Furthermore, the heating element includes a heating coil, which includes a third water inlet and a third water outlet. The third water inlet is connected to the first water outlet via a first pipe section, and the third water outlet is connected to the second water inlet via a second pipe section.
[0010] Furthermore, the heating coil includes multiple vertical pipe sections and multiple bent pipe sections. The multiple vertical pipe sections are spaced apart along a first direction, and each pair of adjacent vertical pipe sections are connected and communicated through a bent pipe section.
[0011] Furthermore, a third pipe section is provided at the first water inlet, and the third pipe section is connected to the outside.
[0012] Furthermore, it also includes a water pump, which is connected to the third pipe section.
[0013] Furthermore, a fourth pipe section is provided at the second water outlet, and the fourth pipe section is connected to the external structure.
[0014] Furthermore, it includes a housing having a mounting cavity, in which the heating element and the water tank are both mounted.
[0015] Furthermore, the housing is provided with a plurality of heat dissipation holes, which are connected to the mounting cavity.
[0016] Furthermore, the housing is provided with at least two through holes, which are connected to the mounting cavity.
[0017] Furthermore, the heat-conducting plate is made of metal.
[0018] In summary, the novel water heater provided by this utility model has the following technical effects: It divides the water storage chamber into two independent sections, a first section and a second section, through a heat-conducting plate. Cold water is introduced through the first inlet of the first section and heated by a heating element. The heated water is then introduced into the second section through the first outlet of the first section, and hot water is discharged from the second outlet of the second section for user use. When the user stops using the water, the residual hot water in the second section can transfer heat to the cold water in the first section through the heat-conducting plate, causing the residual hot water to cool down quickly. Thus, upon restarting, the cooled residual hot water mixes with the newly heated hot water, effectively preventing a sudden rise in water temperature, reducing the risk of scalding, and simultaneously achieving secondary utilization of heat, improving energy efficiency.

[0033] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0034] See Figures 1 to 6 This utility model discloses a novel water heater, including a water heater body 10 and a water tank 20. The water heater body 10 is provided with a heating element 11 for heating. The water tank 20 has a water storage cavity 21, and a heat-conducting plate 22 is provided in the water storage cavity 21. The heat-conducting plate 22 divides the water storage cavity 21 into a first cavity section 211 and a second cavity section 212. The first cavity section 211 has a first inlet 2111 and a first outlet 2112. The first inlet 2111 is used to guide water flow into the first cavity section 211. The second cavity section 212 has a second inlet 2121 and a second outlet 2122. The second inlet 2121 is connected to the first outlet 2112, and the second outlet 2122 is used to guide water flow out.
[0035] Based on the above structure, during assembly, the first water inlet 2111 on the first cavity 211 is connected to the external water circuit through a pipe to introduce cold water into the first cavity 211. Then, the cold water is heated by the heating element 11. The heated water is introduced into the second cavity 212 through the second water inlet 2121 and then introduced to the outside through the second water outlet 2122 for user use.
[0036] When the user stops using the water, the residual high-temperature water in the second chamber 212 can transfer heat to the first chamber 211 through the heat conduction plate 22, and be absorbed by the cold water in the first chamber 211, thus effectively cooling the high-temperature water in the second chamber 212. In this way, when the user restarts the water heater, since the residual high-temperature water in the second chamber 212 has been effectively cooled, the hot water introduced into the second chamber 212 will not suddenly heat up after combining with the cooled water in the second chamber 212, thus preventing the outgoing water temperature from being too high. This indirectly reduces the outlet water temperature, reduces the risk of the user being scalded, and improves the safety of use.
[0037] It should be noted that, under normal use, the water in the first chamber 211 and the second chamber 212 stays for a very short time and the amount of heat exchange is very small, so it will not affect the outlet water temperature, allowing users to use warm water normally.
[0038] More specifically, when restarted, the water remaining in the first chamber 211 has absorbed the heat from the high-temperature water in the second chamber 212, thus preheating the cold water in the first chamber 211. This effectively shortens the heating time of the heating element 11, reduces the consumption of electricity or gas, and improves energy efficiency.
[0039] It should be noted that the heating element 11 in this embodiment can be an existing shell-and-tube heat exchanger (such as a metal shell-and-tube heat exchanger, a finned shell-and-tube heat exchanger, etc.) or a plate heat exchanger. During assembly, the heating element 11 is built into the first cavity 211. On this basis, the first outlet 2112 of the first cavity 211 is directly connected to the second inlet 2121 through a pipe (such as a stainless steel pipe, a copper pipe, or a plastic pipe, etc.). In this way, the water directly heated by the built-in heating element 11 in the first cavity 211 can be directly introduced into the second cavity 212 through the pipe (a drive pump can be installed on the pipe to provide driving force so that the water can be introduced and discharged from the two cavities).
[0040] When the heating element 11 is a sleeve-type heating element 11, it can also be placed outside the first cavity section 211. During assembly, the first outlet 2112 of the first cavity section 211 is connected to the inlet of the sleeve-type heating element 11 through a water pipe, and the outlet of the heating element 11 is connected to the second inlet 2121 of the second cavity section 212, forming an external circulation path from the first cavity section 211 to the heating element 11 to the second cavity section 212. At the same time, a heat source (such as an electric heating module) is connected to the outer tube side of the sleeve-type heating element 11. In this way, after the cold water in the first cavity section 211 is transported to the inner tube of the sleeve-type heating element 11, the heat source releases heat on the outer tube side of the heating element 11 (such as a gas combustion heating outer tube or an electric heating wire heating outer tube), and heats the cold water flowing in the inner tube through heat conduction through the tube wall. The heated hot water flows from the outlet to the second inlet 2121 and is introduced into the second cavity section 212 to complete the heating cycle.
[0041] Of course, the heating element 11 can also be an existing burner (such as a cast iron burner or an aluminum burner). During heating, the gas is sprayed out through the nozzle and mixed with air in the burner to generate high-temperature flue gas. The heat energy of the high-temperature flue gas is transferred to the first chamber through a heat exchange structure (such as a heat exchange tube or fins) to achieve heating. The specific implementation method can be set according to actual needs, and will not be described in detail here.
[0042] Furthermore, the heat-conducting plate 22 in this embodiment can be made of existing metal materials with good thermal conductivity, such as copper plates, aluminum plates, or stainless steel plates. Of course, it can also be made of non-metallic thermally conductive materials, such as graphite or aluminum nitride. The heat-conducting plate 22 is fixed to the inside of the box by welding, gluing, or by connecting parts, so that the inside of the box is divided into two parts to form a first cavity segment 211 and a second cavity segment 212.
[0043] Preferably, the heat-conducting plate 22 in this embodiment is made of metal, such as stainless steel or copper, which are metals with good thermal conductivity.
[0044] Furthermore, the heating element 11 includes a heating coil 111, which includes a third water inlet 1111 and a third water outlet 1112. The third water inlet 1111 is connected to the first water outlet 2112 via the first pipe section 31, and the third water outlet 1112 is connected to the second water inlet 2121 via the second pipe section 32.
[0045] Specifically, during assembly, the heating coil 111 can be made of metal pipes such as copper or stainless steel pipes, which can be directly connected to the circuit. In this way, cold water is introduced from the first pipe section 31 at the first outlet 2112 of the first chamber section 211 to the third inlet 1111, and then into the heating coil 111. When the heating coil 111 is powered on, it can directly heat the cold water flowing inside. Subsequently, the heated water is introduced through the second pipe section 32 at the third outlet 1112 to the second inlet 2121, and then through the second inlet 2121 into the second chamber section 212 for user use.
[0046] Alternatively, a gas heat source (such as a condensing or fully premixed burner) can be installed around the heating coil 111. The gas burns in the combustion chamber outside the coil, producing high-temperature flue gas. This flue gas washes over the outer wall of the heating coil 111, and the heat is conducted to the cold water inside the tube through the metal tube wall, thus heating the cold water. Another option is to install an electric heat source (such as a resistance heating wire) around the outer wall of the heating coil 111. The heating wire is wound around the outer wall of the coil or embedded in the tube wall. When energized, it generates heat through resistance, and the heat conduction heats the water flow inside the tube, achieving heating in the same way.
[0047] More specifically, the heating coil 111 in this embodiment includes multiple vertical pipe sections and multiple bent pipe sections. The multiple vertical pipe sections are spaced apart along the first direction, and each pair of adjacent vertical pipe sections is connected and circumvented by a bent pipe section. In this way, by alternately connecting the vertical pipe sections and the bent pipe sections, the heating coil 111 forms a longer flow channel within a limited space, which prolongs the residence time of cold water in the coil, increases the contact time with the heat source (such as electric heating or steam), and results in more complete heat absorption and better heating effect.
[0048] Furthermore, a third pipe section 33 is provided at the first water inlet 2111, and the end of the third pipe section 33 away from the first water inlet 2111 is connected to the external water passage so that external cold water can be introduced into the first cavity section 211 through the third pipe section 33.
[0049] Specifically, a water pump 50 is installed at the third pipe section 33. The water pump 50 is connected to the third pipe section 33 so that the water pump 50 can provide driving force to make the external cold water flow into the first cavity section 211 continuously and stably, and push the water to flow through the heating coil 111 and the second cavity section 212 in sequence to form a closed loop circulation.
[0050] It should be noted that the water pump 50 can be an existing centrifugal pump, gear pump, or magnetic drive pump, etc.
[0051] Similarly, a fourth pipe section 34 is provided at the second water outlet 2122. The fourth pipe section 34 is connected to an external structure (such as a shower head or faucet) to allow users to use water normally.
[0052] It should be noted that the first pipe section 31, the second pipe section 32, the third pipe section 33 and the fourth pipe section 34 in this embodiment can all be made of metal or plastic water pipes or diversion pipes, etc.
[0053] Furthermore, the device includes a housing 40, which has a mounting cavity 41, in which the heating element 11 and the water tank 20 are both mounted.
[0054] Specifically, the main body 10 of the water heater, the water tank 20, and the pipes are installed inside the shell 40. The shell 40 protects the internal heating element 11, water tank 20 and other components from external impacts (such as collisions and vibrations) or dust intrusion, reducing the probability of damage to the internal structure of the shell 40 and indirectly improving the service life of the entire structure.
[0055] More specifically, the housing 40 is provided with multiple heat dissipation holes 43, which are connected to the mounting cavity 41. The heat dissipation holes 43 achieve heat exchange through air convection, allowing the hot airflow inside the mounting cavity 41 to be discharged to the external environment, thereby cooling the inside of the mounting cavity 41, preventing the internal structure of the mounting cavity 41 from overheating and being damaged, and improving the service life of the entire water heater.
[0056] In addition, at least two through holes 42 are provided on the housing 40, and the at least two through holes 42 are connected to the mounting cavity 41 so that pipes (such as the third pipe section 33 and the fourth pipe section 34) can be connected through the through holes 42 to initially position the pipes, so that the pipes are more stable after installation and less prone to shaking.
[0057] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
