Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a heating tank and water purification equipment. Background Art

[0002] In the water purification equipment, the heating tank is used to heat the water flow to obtain hot water for use. Among them, the heating tank is provided with a water outlet, and the heating tank includes a water inlet pipe and a heating pipe. After the external water source enters the heating tank through the water inlet pipe and is heated by the heating pipe in the heating tank, the hot water is discharged from the water outlet of the heating tank for use.

[0003] After the heating pipe heats the water, it will be stored in the heating tank until the user needs water. However, in the current heating tank, the temperature of the hot water may drop during the storage process. If it is discharged at this time, the water temperature will not be high enough; or when a large flow of hot water is needed, the heating pipe cannot heat the water in time. Such a heating tank cannot achieve the effect of instant heating. Utility Model Content

[0004] The embodiments of the utility model aim to provide a heating tank and a water purification device to solve the technical problem in the prior art that the heating tank cannot achieve an instantaneous heating effect.

[0014] In some embodiments, it further comprises a water inlet pipe, which is inserted into the first tank body and comprises a water inlet end and a water outlet end.

[0015] The water inlet end is exposed on the first tank body and is used to connect to an external water source;

[0016] The water outlet is located in the first tank body and is used to introduce external water into the first tank body.

[0017] In some embodiments, the water outlet is close to the bottom of the first tank.

[0018] In some embodiments, a plurality of water outlet holes are provided on the water outlet end, and the plurality of water outlet holes are evenly distributed on the outer peripheral side of the water outlet end.

[0019] In some embodiments, a dry-burn prevention temperature sensor is also included, and the dry-burn prevention temperature sensor is disposed in the first tank body and close to the surface of the first heating tube.

[0020] In some embodiments, the distance between the second heating tube and the inner wall of the second tank body is greater than 4 mm.

[0021] In some embodiments, the first tank body includes a top cover, and a plurality of fixing holes are provided on the top cover, and the first heating tube, the second heating tube and the anti-dry-burning temperature sensor are all installed on the top cover through the fixing holes.

After the water flow is preliminarily heated in the first tank body, it can flow to the second tank body and be discharged through the water outlet on the second tank body. The diameter of the second tank body is smaller than the diameter of the first tank body. When the water flow in the first tank body enters the second tank body, the heat transfer can be faster because the cavity of the second tank body is smaller than that of the first tank body. At this time, the water can obtain more heat in the second tank body in a short time, thereby improving the instantaneous heating effect of the water flow. Through such a setting, the water flow passing through the second tank body can be raised to a higher temperature in a short time, thereby achieving an instantaneous heating effect.

[0033] In the embodiment of the utility model, the water purification device can heat the water flow through the heating tank to obtain hot water for use.

[0034] Combine the following Figures 1 to 4 , the heating tank and water purification equipment provided in the embodiments of the present application are described in detail through specific examples.

[0035] Please also read Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of a heating tank provided by one embodiment of the utility model; Figure 2 It is a cross-sectional view of a heating tank provided in one embodiment of the present invention. A heating tank 100 provided in one embodiment of the present invention is applied to a water purification device (not shown in the figure). The heating tank 100 includes a first tank body 10, a second tank body 20, a first heating tube 11 and a second heating tube 21. The first tank body 10 is used to store water; the second tank body 20 is arranged on the top of the first tank body 10, and the first tank body 10 and the second tank body 20 are interconnected, and a water outlet 22 is arranged on the second tank body 20, and the water flow in the first tank body 10 can be discharged through the water outlet 22 of the second tank body 20; the first heating tube 11 is arranged in the first tank body 10, and is used for preliminarily heating the water in the first tank body 10; the second heating tube 21 is arranged in the second tank body 20, and is used for secondary heating of the water flow; wherein the diameter of the second tank body 20 is smaller than the diameter of the first tank body 10.

[0036] It should be noted that in the water purification device, unheated or insufficiently heated water can be stored in the first tank body 10. The first tank body 10 and the second tank body 20 are connected to each other, and the first tank body 10 is located at the bottom of the second tank body 20. When hot water needs to be exported, the hot water in the first tank body 10 can be exported through the second tank body 20.

[0037] The water flows in the following direction: after entering the first tank body 10, the water is stored in the first tank body 10, and when hot water is needed, the water in the first tank body 10 can flow to the second tank body 20. In the second tank body 20, the water is further heated by the second heating pipe 21 of the second tank body 20 and then discharged through the water outlet 22.

[0038] The first tank body 10 is provided with a first heating tube 11, which is used to preliminarily heat the first tank body 10 so that the water in the first tank body 10 has a certain initial temperature. For example, the water in the first tank body 10 can reach a temperature of about 70° after being heated by the first heating tube 11. With such a configuration, when the subsequent water flows through the second tank body 20, the second heating tube 21 in the second tank body 20 heats it, thereby achieving an instantaneous heating effect.

[0039] The second tank body 20 is provided with a second heating pipe 21 for secondary heating the water flowing into the second tank body 20 , so that the water with the initial temperature can be heated again and then discharged, thereby obtaining boiling hot water for use.

[0040] In this embodiment, the second tank body 20 is located at the top of the first tank body 10, and the first heating tube 11 and the second heating tube 21 for heating the water flow are respectively arranged in the first tank body 10 and the second tank body 20. After the water flow is preliminarily heated in the first tank body 10, it can flow to the second tank body 20 and be discharged through the water outlet 22 on the second tank body 20. The diameter of the second tank body 20 is smaller than the diameter of the first tank body 10. When the water flow in the first tank body 10 enters the second tank body 20, since the cavity of the second tank body 20 is smaller than that of the first tank body 10, the heat transfer can be faster. At this time, the water can obtain more heat in the second tank body in a short time, thereby improving the instantaneous heating effect of the water flow. Through such a setting, the water flow passing through the second tank body 20 can increase a higher temperature in a short time, thereby achieving an instantaneous heating effect.

[0041] In some specific examples, the first heating tube 11 and the second heating tube 21 can be made of metal materials such as stainless steel, copper, nickel alloy, titanium alloy, etc. Among them, stainless steel has excellent corrosion resistance and high temperature resistance. The stainless steel material can resist corrosive substances in the water. At the same time, it has good thermal conductivity and can quickly transfer heat to the water. Metal copper has good thermal conductivity, can quickly transfer heat to the water, and has high corrosion resistance. Nickel alloy has good high temperature resistance and corrosion resistance, and is suitable for some high temperature or corrosive medium heating scenarios. Titanium alloy has excellent corrosion resistance and light weight, and is suitable for special environments that require corrosion resistance.

[0042] In some more specific examples, the power of the first heating tube 11 can be selected to be 1500W, so as to quickly preheat the water in the first tank body 10 to an initial temperature of 70-80°C. The power of the second heating tube 21 can be selected to be 2100W, which has a higher heating efficiency and is used to achieve an instantaneous heating effect when the water flows through the second tank body 20.

[0043] In some embodiments, part of the first heating tube 11 is spirally arranged in the first tank body 10. The spiral first heating tube 11 can increase the surface area of ​​the first heating tube 11, and has more surface area than the conventional first heating tube 11. By setting the first heating tube 11 in a spiral shape, the length of the first heating tube 11 in the first tank body 10 can be increased, and it can be arranged more compactly in the first tank body 10. Through such a setting, the contact area between the first heating tube 11 and the water can be increased, thereby increasing the heat transfer efficiency.

[0044] In addition, by configuring the first heating tube 11 to be spiral, a more uniform heating effect can be achieved. Since the first heating tube 11 extends along a spiral path, the water is heated more evenly when flowing through. In contrast, a conventionally shaped heating tube may cause the water flow to be overheated when contacting certain areas of the first heating tube 11, while other areas are less heated, resulting in uneven temperature.

[0045] In some other examples, the end of the first heating tube 11 is exposed from the first tank body 10 , and a connecting terminal is provided at the end of the first heating tube 11 for connecting to an external power source to provide electrical energy to heat the first heating tube 11 .

[0046] In some embodiments, part of the second heating tube 21 is spirally arranged in the second tank body 20. The spiral second heating tube 21 can increase the surface area of ​​the second heating tube 21, and has more surface area than the conventional second heating tube 21. By setting the second heating tube 21 in a spiral shape, the length of the second heating tube 21 in the second tank body 20 can be increased, and it can be arranged more compactly in the second tank body 20. Through such a setting, the contact area between the second heating tube 21 and the water can be increased, thereby increasing the heat transfer efficiency.

[0047] In addition, by configuring the second heating tube 21 to be spiral, a more uniform heating effect can be achieved. Since the second heating tube 21 extends along a spiral path, the water is heated more evenly when flowing through. In contrast, a conventionally shaped heating tube may cause the water flow to be overheated when contacting certain areas of the second heating tube 21, while other areas are less heated, resulting in uneven temperature.

[0048] In some other examples, the end of the second heating tube 21 is exposed from the second tank body 20 , and a connecting terminal is provided at the end of the second heating tube 21 for connecting to an external power source to provide electrical energy to heat the second heating tube 21 .

[0049] See also Figure 3 , Figure 3 1 is a schematic diagram of the structure of the water inlet pipe provided by one embodiment of the utility model. In some embodiments, it also includes a water inlet pipe 30, which is inserted into the first tank body 10, and the water inlet pipe 30 includes a water inlet end 31 and a water outlet end 32. The water inlet end 31 is exposed to the first tank body 10 and is used to connect to an external water source; the water outlet end 32 is located in the first tank body 10 and is used to introduce the external water source into the first tank body 10.

[0050] External water can enter the water inlet pipe 30 through the water inlet end 31, flow in the water inlet pipe 30 to the water outlet end 32, and enter the first tank 10 from the water outlet end 32. A valve can be provided at the water inlet end 31 to accurately control the inflow of water.

[0051] In some embodiments, the water outlet 32 ​​is close to the bottom of the first tank body 10. By setting the water outlet 32 ​​of the water inlet pipe 30 at the bottom of the first tank body 10, when the normal temperature water enters the first tank body 10, it specifically flows to the bottom of the first tank body 10, and moves up slowly and evenly after entering the first tank body 10. This upward movement process will push the hot water to move upward as a whole, effectively reducing the retention time of the hot water in the tank, maintaining the uniformity of the water temperature in the tank, and reducing the possibility of water temperature stratification.

[0052] More specifically, the water outlet end 32 can be set in the middle position of the bottom of the first tank body 10. By setting the water outlet end 32 in the middle position of the bottom of the first tank body 10, water can flow evenly into the tank body from the middle position, thereby ensuring that the water flow in the first tank body 10 is more evenly distributed.

[0053] In some embodiments, a plurality of water outlet holes 321 are disposed on the water outlet end 32 , and the plurality of water outlet holes 321 are evenly distributed on the outer peripheral side of the water outlet end 32 .

[0054] By providing a plurality of water outlet holes 321 on the outer peripheral side of the water outlet end 32, normal temperature water can enter the bottom of the tank uniformly from the plurality of water outlet holes 321 and be discharged laterally. In this way, the water flow can be more evenly distributed at the bottom of the tank, and the water flow can be prevented from being concentrated in only one area, thereby improving the uniformity of the water flow. In addition, the provision of a plurality of water outlet holes 321 can enable the water flow to form more flow paths at the bottom of the tank, prevent the water flow from forming a dead angle at the bottom of the tank, and reduce the possibility of water flow stagnation and water accumulation. In addition, by providing a plurality of water outlet holes 321 at the water outlet end 32, normal temperature water can be discharged laterally in a larger range at the bottom of the tank and fully mixed with hot water. Thus, the rapid mixing of hot water and normal temperature water can be promoted, the uniformity of the overall water temperature can be improved, and the water temperature stratification can be prevented. In addition, the plurality of water outlet holes 321 can increase the total outlet area of ​​the water outlet end 32, thereby increasing the speed and pressure of the water flow entering the bottom of the tank. In this way, the energy of the water flow can be increased, and the movement of the water flow at the bottom of the tank can be accelerated, thereby enhancing the stirring and mixing effects. Through such an arrangement, the water outlet 32 ​​can discharge the normal temperature water uniformly, thereby improving the uniformity and mixing effect of the water flow in the first tank body 10 .

[0055] In some embodiments, an anti-dry-burn temperature sensor 40 is also included, and the anti-dry-burn temperature sensor 40 is arranged in the first tank body 10 and close to the surface of the first heating tube 11. The anti-dry-burn temperature sensor 40 can be used as a sensor to monitor the internal temperature of the heating tank 100. Specifically, a mounting tube can be provided in the heating tank 100, and the mounting tube is inserted in the first tank body 10, and the anti-dry-burn temperature sensor 40 is arranged in the mounting tube. Thereby, the anti-dry-burn temperature sensor 40 is arranged in the first tank body 10, and the anti-dry-burn temperature sensor 40 is isolated from the water in the first tank body 10 by the mounting tube. In addition, when the first heating tube 11 is arranged in a spiral shape, the first heating tube 11 may have multiple heating sections, and the anti-dry-burn temperature sensor 40 can detect multiple heating sections at the same time. More specifically, the anti-dry-burning temperature sensor 40 is connected to the sudden jump thermostat. When the temperature of any section of the heating part on the first heating tube 11 exceeds a certain set value, the anti-dry-burning temperature sensor 40 detects that the value exceeds the standard, and the sudden jump thermostat can perform a power-off operation to protect the first heating tube 11 and the heating tank 100 to prevent the first heating tube 11 from dry burning.

[0056] This arrangement can effectively prevent the first heating tube 11 from failing to work properly for a long time and causing dry burning, thereby preventing the liquid inside the heating tank 100 from overheating, reducing the risk of explosion, overflow or damage, and improving the safety and reliability of the device.

[0057] Among them, a reasonable temperature threshold can be set according to actual conditions to determine whether there is a risk of dry burning of the first heating tank 100.

[0058] In some embodiments, the distance between the second heating tube 21 and the inner wall of the second tank body 20 is greater than 4 mm. Keeping the distance between the second heating tube 21 and the inner wall of the second tank body 20 greater than 4 mm can avoid excessive heat conduction and prevent the tank wall temperature from being too high. Excessive tank wall temperature may cause deformation and aging of the tank material, or affect the structure and performance of the tank. By making the distance between the second heating tube 21 and the inner wall of the second tank body 20 greater than 4 mm, the safety and stability of the second tank body 20 can be ensured. In addition, by setting the distance between the second heating tube 21 and the inner wall of the second tank body 20 greater than 4 mm, the risk of dry burning can be reduced. Excessive tank wall temperature may cause liquid residue near the heating tube to evaporate rapidly, thereby causing dry burning. By maintaining an appropriate distance, excessive heat conduction can be avoided, the possibility of rapid evaporation of liquid can be reduced, and the risk of dry burning can be reduced.

[0059] See also Figure 4 , Figure 41 is a partial structural diagram of a heating tank provided in one embodiment of the utility model. In some embodiments, the first tank body 10 includes a top cover 50, and the top cover 50 is provided with a plurality of fixing holes 51, and the first heating tube 11, the second heating tube 21 and the anti-dry-burning temperature sensor 40 are all installed on the top cover 50 through the fixing holes 51.

[0060] By opening a fixing hole 51 on the top cover 50, it is convenient to install the first heating tube 11, the second heating tube 21 and the anti-dry-burning temperature sensor 40. Specifically, the first heating tube 11, the second heating tube 21 and the anti-dry-burning temperature sensor 40 can be welded to the top cover 50 through the fixing hole 51. With such an arrangement, it has better manufacturing processability.

[0061] Furthermore, before the first heating tube 11 and the second heating tube 21 are installed, the first heating tube 11 and the second heating tube 21 may be inspected first, so as to prevent the first heating tube 11 or the second heating tube 21 from being damaged and failing to work normally.

[0062] Another embodiment of the utility model provides a water purification device (not shown in the figure), including the above-mentioned heating tank 100. The second tank body 20 is located on the top of the first tank body 10, and the first heating tube 11 and the second heating tube 21 for heating the water flow are respectively arranged in the first tank body 10 and the second tank body 20. After the water flow is preliminarily heated in the first tank body 10, it can flow to the second tank body 20 and be discharged through the water outlet 22 on the second tank body 20. The diameter of the second tank body 20 is smaller than the diameter of the first tank body 10. When the water flow in the first tank body 10 enters the second tank body 20, the flow speed of the water flow will be accelerated. At this time, the water is more fully in contact with the second heating tube 21 in a short time, thereby improving the instantaneous heating effect of the water flow. Through such a setting, the water flow passing through the second tank body 20 can be raised to a higher temperature in a short time, thereby achieving an instantaneous heating effect.

It can be understood that the water purification equipment provided in the embodiment of the utility model also includes other structures for realizing the functions of the water purification equipment, including but not limited to waterway plate structure, filter element structure, etc.
