Description

Technical Field

[0001] This utility model relates to the field of hot water tank technology, and in particular to a hot water tank that suppresses large fluctuations in water temperature. Background Technology

[0002] Hot water tanks are core equipment for storing and providing hot water, and are widely used in homes, industries, and commercial settings. They reduce heat loss through insulation layers and maintain the water temperature within a set range.

[0003] As described in announcement number CN208332408U, a hot water storage tank includes an insulated body. A water inlet pipe is located on the lower side of the insulated body, and a first flow stabilizing plate is located on the upper side of the water inlet pipe. A second flow stabilizing plate is located on the upper side of the first flow stabilizing plate, and a water outlet pipe is located between the second flow stabilizing plate and the top of the insulated body. The first flow stabilizing plate includes a plate body with a plurality of evenly distributed circular holes. Utilizing the natural principle that hot water has a lower specific gravity than cold water, the heavier cold water enters the bottom of the insulated body in an orderly manner, pushing the hot water stored in the insulated body in layers to the water outlet at the top of the insulated body. This avoids mixing of hot and cold water, increases the outlet water temperature, and under the same operating conditions, can increase the heat storage and release capacity by more than 10% compared to existing hot water storage tanks, improve the operating efficiency of the heating system, and reduce heating energy consumption by more than 10%.

[0004] This patent can improve the operating efficiency of the heating system. However, when cold water is added to the existing water tank, the water flow is relatively concentrated. When the water pressure is high, the speed is fast, and the cold water diffusion will agitate the upper hot water area, causing fluctuations in the outlet temperature. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in existing water tanks, when cold water is added, the water flow is relatively concentrated, and when the water pressure is high, the speed is fast. The cold water diffusion will agitate the upper hot water area, causing fluctuations in the outlet temperature.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hot water tank for suppressing large fluctuations in water temperature, comprising a hot water tank body, an anti-fluctuation component disposed inside one side of the hot water tank body, the anti-fluctuation component comprising a water inlet sleeve, a perforated pipe connected to the bottom of the water inlet sleeve, the perforated pipe having holes evenly spaced on its surface, a first temperature sensor, a second temperature sensor and a third temperature sensor respectively connected to the upper, middle and lower front ends of the water inlet sleeve, a PLC controller connected to one side of the outer surface of the hot water tank body, and three sets of indicator lights connected to one side of the PLC controller.

[0007] Furthermore, the PLC controller is connected to an external power supply via a control switch, and the PLC controller is also connected to the first temperature sensor, the second temperature sensor, the third temperature sensor, and three sets of indicator lights via wires.

[0008] Furthermore, the bottom surface of the porous tube is 200mm above the bottom of the hot water tank body, and both ends are sealed, with each end 100mm from the inner wall of the hot water tank body.

[0009] Furthermore, the diameter of the holes is 15mm, and the spacing between each group of holes is 50mm.

[0010] Furthermore, a filter assembly is provided at the upper end of the water inlet sleeve. The filter assembly includes a flow sensor, with a water inlet pipe connected to the top of the flow sensor and a filter sleeve connected to one side of the water inlet pipe.

[0011] Furthermore, the surface of the filter sleeve is provided with a groove, the inside of the groove is provided with a sealing ring, the inside of the filter sleeve is provided with a filter box, one side of the filter sleeve is connected to a front cover, one side of the front cover is connected to a water inlet hose, and five sets of limiting cylinders are circumferentially connected to the surface of the front cover.

[0012] Furthermore, each set of limiting cylinders has a hand-tightening bolt inserted inside, and a limiting block is fixedly connected to the surface of the hand-tightening bolt. An alarm is connected to the surface of the hot water tank body near the indicator light.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when water is discharged, after the cold water enters the inlet sleeve, the speed will decrease due to the increased pipe diameter. At the bottom, the multi-hole pipe will evenly enter the hot water tank body through the dispersed holes, without forming a strong water flow, thus avoiding disturbing the distribution of hot water inside the hot water tank and achieving the purpose of stabilizing the water temperature of the hot water tank.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1 - Figure 2 As shown, this utility model provides a hot water tank that suppresses large fluctuations in water temperature, including a hot water tank body 1. An anti-fluctuation component 2 is installed inside one side of the hot water tank body 1. The anti-fluctuation component 2 includes an inlet sleeve 201, with a perforated pipe 202 connected to the bottom of the inlet sleeve 201. Holes 203 are equidistantly distributed on the surface of the perforated pipe 202. A first temperature sensor 204, a second temperature sensor 205, and a third temperature sensor 206 are respectively connected to the upper, middle, and lower front ends of the inlet sleeve 201. The outer surface of one side of the hot water tank body 1... A PLC controller 207 is connected to the surface of the hot water tank. Three sets of indicator lights 208 are connected to one side of the PLC controller 207. The PLC controller 207 is connected to an external power supply via a control switch. The PLC controller 207 is also wired to the first temperature sensor 204, the second temperature sensor 205, the third temperature sensor 206, and the three sets of indicator lights 208. The bottom surface of the porous tube 202 is 200mm above the bottom of the hot water tank body 1, and both ends are sealed. Each end is 100mm from the inner wall of the hot water tank body 1. Holes 203 are present. The aperture is 15mm, and the spacing between each group of holes is 50mm.

[0020] The effect achieved in Embodiment 1 is that when cold water is released, after the cold water enters the inlet sleeve 201, the speed will decrease due to the increased pipe diameter. At the bottom, the porous pipe 202 enters the hot water tank body 1 evenly through the dispersed holes 203, without forming a strong water flow, thus avoiding disturbing the distribution of hot water inside the hot water tank and achieving the purpose of stabilizing the water temperature in the hot water tank. At the same time, the first temperature sensor 204, the second temperature sensor 205, and the third temperature sensor 206 can monitor the water temperature at different depths respectively. The PLC controller 207 can drive the three sets of indicator lights 208 to activate different color functions. The three sets of indicator lights 208 correspond to the three sets of sensors.

[0021] Temperature zone threshold: Top layer: Green <40℃, Yellow 40-60℃, Red ≥60℃.

[0022] Middle layer: Green <50℃, Yellow 50-70℃, Red ≥70℃.

[0023] Lower layer: Green <30℃, Yellow 30-50℃, Red ≥50℃.

[0024] By capturing the vertical temperature distribution of the hot water tank body 1 using a three-layer sensor system, localized overheating or dead zones are avoided. Color gradients replace numerical values, reducing the cognitive load on operators. This system has practical applications in industrial control, commercial heating, and residential appliances. Its innovation lies in combining spatial temperature field monitoring with intuitive human-machine interaction, which improves system safety and reduces operation and maintenance costs.

[0025] Example 2, as Figure 3 and Figure 4 As shown, a filter assembly 3 is provided at the upper end of the inlet sleeve 201. The filter assembly 3 includes a flow sensor 301. The top of the flow sensor 301 is connected to an inlet pipe 302. A filter sleeve 303 is connected to one side of the inlet pipe 302. A groove 304 is provided on the surface of the filter sleeve 303. A sealing ring 306 is provided inside the groove 304. A filter box 305 is provided inside the filter sleeve 303. A front cover 307 is connected to one side of the filter sleeve 303. An inlet hose is connected to one side of the front cover 307. Five sets of limiting cylinders 308 are connected in a ring on the surface of the front cover 307. A hand-tightening bolt 309 is inserted into the inside of each set of limiting cylinders 308. A limiting block 310 is fixedly connected to the surface of the hand-tightening bolt 309. An alarm 311 is connected to the surface of the hot water tank body 1 near the indicator light 208.

[0026] The effect achieved in Embodiment 2 is that before the water source enters the main body 1 of the hot water tank, it passes through the filter sleeve 303 to filter impurities. When the flow sensor 301 detects a decrease in flow, it sends an electrical signal to the alarm 311, causing the alarm 311 to automatically open, thereby reminding the operator to replace the filter sleeve 303 in time. When replacing the filter sleeve 303, the hand-tightening bolt 309 can be reversed so that the front end of the hand-tightening bolt 309 can be removed from the threaded hole of the filter sleeve 303. Then, the filter box 305 inside the filter sleeve 303 can be removed and replaced. The sealing ring 306 can also play a sealing role. At this time, the front cover 307 is attached to the surface of the filter sleeve 303, and the hand-tightening bolt 309 can be turned to install and fix it, which improves water quality and overall practicality.

[0027] Working principle: When water is discharged, cold water enters the inlet sleeve 201. Due to the increased pipe diameter, the flow rate decreases. At the bottom, the porous pipe 202 flows evenly into the hot water tank body 1 through the dispersed holes 203, without forming a strong water flow. This avoids disturbing the distribution of hot water inside the hot water tank and achieves the purpose of stabilizing the water temperature. During use, the filter box 305 inside the filter sleeve 303 can filter impurities and improve water quality. It can be easily disassembled and replaced by turning the hand-tightening bolt 309, improving overall practicality.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
