Technical Field
[0001] This utility model relates to the field of water heater technology, and in particular to an energy-saving instant hot water heater. Background Technology
[0002] A water heater is a device that heats water to a suitable temperature, providing convenient hot water for homes, offices, or public places. Traditional water heaters require continuous heat preservation of the water tank to ensure a constant supply of hot water. This not only leads to repeated heating of the water, affecting water quality and health, but also causes a large amount of energy waste due to the continuous loss of heat to the outside, increasing operating costs. When a large amount of hot water is used up from the tank, it needs to be reheated before it can be supplied again. During peak water usage periods, it often cannot meet the immediate demand. Energy-saving instant water heaters avoid the water quality problems caused by repeated heating and have become key devices for ensuring drinking water safety and reducing energy consumption.
[0003] Energy-saving instant water heaters need to heat cold water to boiling point or a specified temperature instantly, which requires a large power and specialized circuitry that ordinary household circuits cannot handle, posing safety hazards. The current solution is to combine heat storage with instant heating. Heat is stored during off-peak electricity hours and then combined with instant heating when in use, reducing instantaneous power consumption and improving safety. However, the problem of unused residual heat from hot water and impurities in the water directly contacting the outer wall of the heating element, hindering heat transfer, leads to decreased heat transfer efficiency and energy waste. Utility Model Content

A valve is rotatably connected to the top of the water outlet. An opening component is provided on the rear side of the tank.
[0007] As a further description of the above technical solution:
[0008] The replacement mechanism includes two housings, with adjacent sides of the two housings fixedly connected to the left and right sides of the box body, respectively. Screws are rotatably connected inside each of the two housings, and knobs are fixedly connected to the opposite sides of the two screws. Displacement plates are threadedly connected to the middle of each of the two screws, and engaging plates are fixedly connected to adjacent sides of the two displacement plates. A water tank is slidably connected to the top rear side of the box body, and engaging grooves are provided on both the left and right sides of the water tank. Adjacent sides of the two engaging plates engage with the corresponding engaging grooves. A pulling assembly is fixedly connected to the top of the water tank, and a limit plate is fixedly connected to the upper middle part of the rear side of the box body.
[0009] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:
[0018] The box body has multiple ventilation openings on both the left and right sides. The ventilation openings are equidistant and have an inclined angle.
[0019] As a further description of the above technical solution:
[0020] A water receiving plate is fixedly connected to the middle of the front side of the box, and the top of the water receiving plate has multiple grooves.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, water is drawn through an extraction pipe and enters the cold water pipe through a filter shell. The filter shell can reduce impurities in the water and prevent impurities from adhering to the outer wall of the heating pipe, thereby improving heat transfer efficiency. By using a structural design in which the cold water pipe is inserted into the hot water pipe in a way that fits the outer wall, the residual heat of the hot water is used to preheat the water flow in the cold water pipe, thereby increasing the initial temperature of the cold water and reducing energy consumption costs.
[0023] 2. In this utility model, the screw is driven to rotate by rotating the knob, which in turn drives the displacement plate to move left and right, so that the locking plate separates from the locking groove. Then, the pulling component is pulled to complete the disassembly, and the reverse is performed for installation. This realizes the quick disassembly and replacement of the water tank, avoiding the need for additional tools during replacement, avoiding the problems of poor compatibility and inconvenient replacement, and improving the replacement efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0032] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model is provided: an energy-saving instant hot water dispenser, including a box body 1 and a tray 4. The box body 1 is provided with a preheating mechanism 2, which is used to preheat low-temperature water. The box body 1 is provided with a replacement mechanism 3, which is used to improve replacement efficiency. The box body 1 is provided with multiple support mechanisms 5 at the bottom, which are used to improve the stability of the box body 1.
[0033] The preheating mechanism 2 includes a heating shell 201, the bottom of which is fixedly connected to the top of the tray 4. The heating shell 201 provides space for heating. Multiple heating tubes 202 are fixedly connected to the inner wall of the heating shell 201. The heating tubes 202 are used to heat cold water. A cold water pipe 203 is connected to the right side of the heating shell 201. A filter shell 204 is connected to the end of the cold water pipe 203. The filter shell 204 is used to filter the cold water. An extraction pipe 205 is connected to the top of the filter shell 204. A hot water pipe 206 is connected to the left side of the heating shell 201. The outer wall of the cold water pipe 203 penetrates the interior of the hot water pipe 206. The outer wall of the hot water pipe 206 penetrates the front side of the tank 1 and is connected to a water outlet 207. The water outlet 207 is used to export the heated hot water for use. A valve 208 is rotatably connected to the top of the water outlet 207. The valve 208 enables flexible control of the hot water output. An opening component 209 is provided on the rear side of the tank 1.
[0034] Specifically, the housing 1 serves as the main frame of the entire equipment. Its internal preheating mechanism 2 preheats the low-temperature water, improving energy efficiency. The replacement mechanism 3 at the rear of housing 1 shortens maintenance time and improves overall replacement efficiency. Multiple support mechanisms 5 at the bottom effectively reduce vibration during equipment operation by providing stable support to housing 1, thus enhancing the overall structural stability. The preheating mechanism 2 uses the heating shell 201 as its core carrier, with its bottom fixed to the top of the support plate 4, providing a closed and stable space for internal heating operations. Multiple heating tubes 202 on the inner wall of the heating shell 201 serve as the main heating elements, raising the temperature of the incoming cold water through heating. The cold water enters the heating shell 201 through the cold water pipe 203 connected to the right side, and the end of the cold water pipe 203 is connected to… The filter housing 204 and the extraction pipe 205 draw cold water into the filter housing 204 for impurity filtration, ensuring the cleanliness and durability of the pipeline and heating element, and improving heating efficiency. The outer wall of the cold water pipe 203 runs through and connects to the inside of the hot water pipe 206. The residual heat of the hot water in the hot water pipe 206 is used to preheat the cold water in the cold water pipe 203, realizing the secondary utilization of heat and further improving heating efficiency. The heated hot water is transported through the hot water pipe 206 and discharged by the outlet 207 for actual use. The valve 208 connected to the top of the outlet 207 can control the start and stop of the hot water output and the flow rate to meet different usage needs. The opening component 209 on the rear side of the housing 1 facilitates the inspection, maintenance or component adjustment of the preheating mechanism 2 to ensure the continuous and stable operation of the equipment.
[0035] Reference Figure 1 , Figure 2 and Figure 5 The replacement mechanism 3 includes two housings 301, with adjacent sides of the two housings 301 fixedly connected to the left and right sides of the housing 1, respectively. The housings 301 provide installation space for internal components and protect the internal structure from external interference, ensuring stable operation of the mechanism. Each housing 301 has a screw 302 rotatably connected inside. A knob 303 is fixedly connected to the opposite side of each screw 302, used to rotate the screw 302. A displacement plate 304 is threadedly connected to the middle of each screw 302. A locking plate 305 is fixedly connected to each adjacent side of 4. The locking plate 305 is used to fix the water tank 306. The water tank 306 is slidably connected to the top rear side of the tank body 1. The left and right sides of the water tank 306 are provided with locking grooves 307. The adjacent side of the two locking plates 305 is locked with the corresponding locking grooves 307. A pulling component 308 is fixedly connected to the top of the water tank 306. The pulling component 308 is used to pull the water tank 306. A limiting plate 309 is fixedly connected to the upper middle part of the rear side of the tank body 1. The limiting plate 309 limits the rear side of the water tank 306.
[0036] Specifically, the replacement mechanism 3, as a key structure ensuring the rapid replacement of core components of the equipment, has two housings 301 fixed to the left and right sides of the housing 1, respectively, providing installation space for internal components and effectively isolating them from external dust and collision interference. The screw 302 rotatably connected inside the housing 301 is the core of the power transmission of the entire mechanism. The screw 302 is driven to rotate by rotating the knob 303. The displacement plate 304 threaded in the middle of the screw 302 plays the role of motion conversion, driving the locking plate 305 to move synchronously. When the locking plate 305 engages with the locking grooves 30 on the left and right sides of the water tank 306, the locking plate 305 moves synchronously. When engaged, the water tank 306, which is slidably connected to the top rear side of the housing 1, can be fixed in place, preventing it from shaking or shifting during equipment operation. When the water tank 306 needs to be replaced, the knob 303 is rotated in the opposite direction to disengage the engagement plate 305 from the engagement groove 307, thus releasing the fixation. The pulling component 308 on the top of the water tank 306 provides a leverage point for disassembly. By holding and pulling this component, the water tank 306 can be pulled out along the rear side of the housing 1, improving replacement efficiency. The limiting plate 309 fixed in the upper middle part of the rear side of the housing 1 serves as a limit, blocking the rear side of the water tank 306.
[0037] Reference Figure 1 and Figure 3 The opening component 209 includes a rotating door 2091, the left side of which is rotatably connected to the rear left end of the housing 1. A sealing ring 2092 is fixedly connected to the front side of the rotating door 2091. Multiple support mechanisms 5 include multiple support columns 501, the top of which is fixedly connected to the bottom of the housing 1, and the bottom of which is fixedly connected to a rubber sleeve 502. Multiple ventilation openings 8 are provided on both the left and right sides of the housing 1. The multiple ventilation openings 8 are equidistant and have an inclined angle.
[0038] Specifically, the sealing ring 2092 enhances the sealing performance, fills the gap between the rotating door 2091 and the housing 1, and prevents dust, moisture, and liquid from entering the internal space through the door gap, thus helping to improve the overall sealing performance of the protective device. Through the connection between the housing 1 and the support mechanism 5, the overall stability of the device can be improved. The multiple ventilation openings 8 are equidistantly opened, which allows the airflow to be evenly distributed inside the housing 1. The inclined angle is set to reduce the direct vertical fall of external dust and debris into the ventilation openings 8, thereby reducing the probability of pollutants entering the housing 1.
[0039] Reference Figure 1 and Figure 2A control switch 9 is fixedly connected to the right side of the housing 1, and the control switch 9 is electrically connected to the heating tube 202; the pull assembly 308 includes a pull rod 3081, the bottom of the pull rod 3081 is fixedly connected to the top of the water tank 306, and rectangular grooves 3082 are provided on both the front and rear sides of the pull rod 3081; a water receiving plate 6 is fixedly connected to the middle of the front side of the housing 1, and multiple grooves 7 are provided on the top of the water receiving plate 6;
[0040] Specifically, the control switch 9, which is electrically connected to the heating tube 202, enables the equipment to be turned on and off. The rectangular grooves 3082 on both the left and right ends of the pull rod 3081 make it easy to hold the pull rod 3081 and pull the water tank 306. The water receiving plate 6 and the groove 7 serve to collect and collect water droplets or splashes during water use, preventing water from dripping directly onto the table or ground below the equipment and keeping the usage environment dry and clean.
[0041] Working principle: When heating cold water, water is first drawn from water tank 306 through extraction pipe 205. The water flow first enters filter shell 204 for pretreatment, intercepting impurities in the water and preventing impurities from adhering and depositing on the outer wall of heating tube 202. This prevents the heat transfer efficiency from decreasing due to dirt blockage, reduces the wear and tear on heating tube 202 caused by impurity corrosion, and extends its service life. The filtered clean water then flows into cold water pipe 203. Cold water pipe 203 is designed to be fitted with the hot water pipe 206, allowing cold water pipe 203 to contact the high-temperature hot water flowing in hot water pipe 206. The residual heat emitted by the hot water during transportation can be transferred to the low-temperature water flow in cold water pipe 203 through the pipe wall, preheating it. This raises the initial temperature of the cold water before it enters heating shell 201, reducing the heating load of heating tube 202 on the cold water, reducing energy consumption, thereby reducing the overall energy cost in long-term use and improving the energy utilization efficiency of the heating system.
[0042] Furthermore, when the water tank 306 needs to be replaced, simply rotate the knob 303 to drive the screw 302 inside the housing 301 to rotate synchronously. The rotation of the screw 302 will drive the displacement plate 304 to move left and right through the threaded transmission, thereby separating the locking plate 305 fixed on the displacement plate 304 from the locking grooves 307 on both sides of the water tank 306, releasing the lock on the water tank 306. Hold the pulling component 308 on the top of the water tank 306 and pull it upward to complete the disassembly operation. Conversely, the water tank 306 can be installed, realizing the quick disassembly and replacement of the water tank 306. This purely manual operation structure design does not require the use of additional tools, avoiding the problem of replacement obstruction caused by poor tool compatibility, saving the tedious steps of finding tools and removing screws, shortening the replacement time, and improving the maintenance efficiency and ease of use of the equipment.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
