Description

Technical Field

[0001] The present disclosure relates to the technical field of instant hot water dispensers, and particularly to a heating device. Background Art

[0002] Currently, instant hot water dispensers use rapid heating elements to quickly heat water. The rapid heating element converts electrical energy into heat energy, and the heat energy then transfers the heat to the water, using the powerful heat to quickly heat the water and obtain hot water rapidly. Due to the large power and high power density of the rapid heating element, the water quickly heats up when it comes into contact with the heating structure inside the rapid heating element, generating a large amount of water vapor. Therefore, it is easy to spray steam when discharging high-temperature water, posing a safety hazard.

[0003] In response to the above problems, the current solutions adopted by rapid heating elements are to lower the maximum temperature setting of the rapid heating element or to increase the water vapor separation structure subsequently. The rapid heating elements adopting these two solutions lack usability and good performance. Utility Model Content

[0008] An eddy current spoiler is arranged at a first position of the heating element tube. The eddy current spoiler is used to disturb the water flow entering the sandwich, so that the water flow entering the sandwich is in a swirling state. The first position is close to one end where the water inlet of the housing is located.

[0009] In a further embodiment, the housing is cylindrical, and the water inlet and the water outlet are respectively arranged at both ends of the housing.

[0010] In a further embodiment, an eddy current spoiler is arranged at a second position of the heating element tube. The eddy current spoiler is used to disturb the water flow at the water outlet, so that the water flow temperature at the water outlet is uniform. The second position is close to one end where the water outlet of the housing is located.

[0011] In a further embodiment, sealing rings are provided on the water inlet and the water outlet, and a temperature sensor is further provided on the water outlet, and the temperature sensor is used to detect the actual water outlet temperature.

[0012] In addition, the present disclosure also proposes a water treatment device, and the water treatment device uses the above-mentioned rapid heating body to heat-treat water.

[0013] In a further embodiment, the water treatment device includes a temperature setting control, and the maximum value of the temperature setting range of the temperature setting control is less than or equal to 100 °C.

[0014] In a further embodiment, the water treatment device further includes a target water outlet, and the target water outlet is used to directly discharge the water heated by the rapid heating body.

[0015] In addition, the present disclosure also proposes a water treatment method, and the method is applied to the above-mentioned water treatment device, and includes:

[0016] Heating the water in the water treatment device based on the rapid heating body in the water treatment device to obtain heated water;

[0017] When the target water outlet of the water treatment device is opened, directly discharging the heated water.

[0018] In a further embodiment, the heating the water in the water treatment device based on the rapid heating body in the water treatment device to obtain heated water includes:

[0019] Opening the water inlet of the rapid heating body, so that water flows into the interior of the rapid heating body from the water inlet of the rapid heating body, and after passing through the vortex turbulator of the rapid heating body, flows around the heating body tube of the rapid heating body in a rotating manner along the heat conduction and fluid guiding body of the rapid heating body to the water outlet of the rapid heating body, to obtain the heated water.

[0020] In a further embodiment, the water flow is disturbed to form a turbulent flow when passing through the vortex turbulator of the rapid heating body, and enters the interior of the rapid heating body with the turbulent flow.

[0021] A heating device, which includes:

[0022] A diversion pipe;

[0023] A heating pipe, the heating pipe is sleeved outside the diversion pipe, and a channel is formed between the heating pipe and the diversion pipe; the inner wall of the heating pipe constitutes a heating body;

[0024] A flow guide ring is arranged between the flow guide pipe and the heating pipe, and divides the channel into a spiral heating channel. The flow guide ring is made of a heat-conducting material, and at least a part of the flow guide ring is in thermal contact with the heating body and forms a heat-conducting path.

[0025] In this solution, the heating device sets a spiral flow guide ring in the interlayer between the heating pipe and the flow guide pipe, reducing the internal volume of the heating device. As a result, the water flow entering the heating device becomes smaller, increasing the water heating speed. Moreover, the spiral heating channel makes the water flow spirally in the heating channel, forming a self-rotating water ring, preventing the water from flowing in a straight line, increasing the contact opportunity between different parts of the water and the heating body, accelerating heat conduction, balancing the temperature of the heating body, avoiding local high-temperature heating points on the heating body, extending the life of the heating body, and also preventing the water from being vaporized, thus not generating steam. At the same time, the self-rotating water ring also accelerates the heat exchange between the water, with a fast temperature rise and small water temperature fluctuations. The spiral heating channel extends the heating path, with a fast heating speed and uniform water temperature.

[0026] In addition, since the flow guide ring is made of a heat-conducting material and is in contact with the heating body, the heating pipe can conduct heat through the spiral flow guide ring, increasing the contact area between the heating body and the water and making the water temperature rise quickly. The flow guide pipe and the flow guide ring are arranged in the heating pipe, making the volume of the heating channel in the interlayer small. Therefore, the thermal expansion and contraction of the heating device are small, and when the heating stops, the amount of heat overflow water is small.

[0027] Preferably, the heating body is configured with a first heat transfer area S1, the flow guide ring is configured with a second heat transfer area S2, and the ratio of the sum of S1 and S2 to S1 is not less than 1.1;

[0028] Wherein, the first heat transfer area S1 is the surface area of the heating body in contact with the water, and the second heat transfer area S2 is the surface area of the flow guide ring in contact with the water.

[0029] In this solution, with the above structure setting, by setting the flow guide ring, compared with not setting the flow guide ring, the heating area of the heating body is significantly increased, improving the heating efficiency.

[0030] Preferably, the flow guide ring is made of a metal material.

[0031] Preferably, the flow guide ring is a separate component arranged between the flow guide pipe and the heating pipe.

[0032] Preferably, the total volume of the heating channel is 25 cubic centimeters, and at least 9 square centimeters of heat transfer area is configured per cubic centimeter of volume.

[0033] In this solution, a diversion ring made of metal material is adopted to improve heat conduction, facilitating the heat of the heating pipe to be transferred to water through the diversion ring, increasing the heating area, and enhancing the heating speed. The diversion ring is a separate accessory, which is convenient for processing and assembly.

[0034] Preferably, the heating device further includes a housing, a water inlet unit, and a water outlet unit. The heating pipe is arranged inside the housing. The water inlet unit is matched with the water inlet end of the heating channel, and the water outlet unit is matched with the water outlet end of the heating channel.

[0035] In this solution, the housing is used for heat preservation to prevent the heat of the heating pipe from being lost, and the housing is also used to protect the heating pipe. The water inlet unit has a water inlet, and the water inlet is used to connect tap water or purified water. Water flows into the heating pipe through the water inlet of the water inlet unit, and after being heated by the heating pipe, the water flows out from the water outlet of the water outlet unit, and the user obtains the required hot water at the water outlet.

[0036] Preferably, the water inlet unit includes a lower housing, and there is a water inlet cavity on the lower housing. A first diverter is arranged at the water inlet end of the heating channel. A plurality of blades are arranged on the first diverter, and diversion channels are formed between adjacent blades. The diversion channels are respectively communicated with the water inlet cavity and the heating channel.

[0037] In this solution, while the first diverter diverts water through the blades, it also turbulizes the water to form a self-rotating water ring, preventing the water from flowing in a straight line, disturbing the water before it enters the heating pipe, increasing the contact opportunities between different parts of the water and the heating body, accelerating heat conduction, balancing the temperature of the heating body, avoiding local high-temperature heating points on the heating body, preventing the water from being vaporized, prolonging the service life of the heating body, and at the same time also accelerating the heat exchange between the water, with small water temperature fluctuations.

[0038] Preferably, the blades are inclined, and the inclination direction of the blades is the same as the rotation direction of the heating channel.

[0039] In this solution, with the above structure, self-rotating water is formed, increasing the contact opportunities between different water and the heating body, accelerating heat conduction, improving the water turbulization effect. At the same time, the self-rotating water also accelerates the heat exchange between the water, with fast and uniform temperature rise. And the self-rotating water has fast heat conduction, balancing the temperature of the heating body, and avoiding local high temperature from burning out the heating body.

[0040] Preferably, the blades are inclined, and the inclination direction of the blades is opposite to the rotation direction of the heating channel.

[0041] In this solution, with the above structure, the water turbulization effect is improved.

[0042] Preferably, the water outlet unit includes an upper housing which has a water outlet cavity. The water outlet end of the heating channel is provided with a second diverter. The second diverter is provided with a plurality of vanes, and diversion channels are formed between adjacent vanes. The diversion channels are respectively communicated with the water outlet cavity and the heating channel.

[0043] In this solution, the second diverter turbulizes the heated high-temperature water, enabling the water to mix quickly and equalize the water temperature at the water outlet.

[0044] Preferably, the vanes are inclined, and the inclination direction of the vanes is opposite to the rotation direction of the heating channel.

[0045] In this solution, with the above structure, the water can flow out smoothly, reducing the water resistance.

[0046] Preferably, the vanes are inclined, and the inclination direction of the vanes is the same as the rotation direction of the heating channel.

[0047] In this solution, with the above structure, the mixing effect of the water is improved, and the water temperature at the water outlet is equalized.

[0048] Preferably, the cross-section of the heating channel along the axial direction of the heating tube has a first dimension segment and a second dimension segment. The first dimension segment is close to the heating tube, and the second dimension segment is located in the middle of the cross-section. The length of the first dimension segment is greater than the length of the second dimension segment.

[0049] In this solution, with the above structure, a narrow-mouth structure in the middle and an open-mouth structure at the ends are formed. The open-mouth structure corresponds to the heating element, with a large water flow rate, enabling a larger-sized heating element to heat the water and improving the heating efficiency. The narrow-mouth structure has a small water flow rate because it is far from the heating element, so as to equalize the heating.

[0050] Preferably, the diversion ring is made of a heat-conducting material. The cross-section of the heating channel along the axial direction of the heating tube is a regular figure, which includes a first straight segment, a first arc segment, a second straight segment, and a second arc segment connected end to end in sequence. The first straight segment and the second straight segment are oppositely arranged, and the first arc segment and the second arc segment are oppositely arranged, and the first arc segment and the second arc segment bulge in the direction of approaching each other.

[0051] In this solution, since the diversion ring is made of a heat-conducting material, the heat of the heating tube can be transferred to the water in the heating channel through the diversion ring, enabling the first straight segment, the first arc segment, and the second arc segment to heat the water simultaneously, increasing the heating area, and improving the heating efficiency.

[0052] Preferably, both ends of the diversion ring in the axial direction of the heating tube are applied with force to maintain elastic potential energy.

[0053] In this solution, the diversion ring can be compressed by the water inlet unit and the water outlet unit to keep the diversion ring in elastic potential energy. On the one hand, the diversion ring is fixed, and on the other hand, the gap between adjacent spirals is kept fixed, preventing the shape of the heating channel from changing and affecting the heating effect.

[0054] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and do not limit the present disclosure.

[0055] Implementing the present disclosure has the following beneficial effects:

[0056] By adding a heat-conducting and heat-conducting fluid inside the instant heating body, the volume inside the instant heating body becomes smaller while the heat-conducting area becomes larger. Therefore, the amount of water flowing into the instant heating body becomes smaller, improving the speed of heating water. The heat-conducting and heat-conducting fluid can also increase the contact amount between different water and the heating body tube. An eddy current spoiler is also provided at the water inlet of the instant heating body to make the water flowing into the instant heating body in a swirling state, making the heated water temperature uniform and not forming water vapor. The high-temperature water heated by the instant heating body can directly flow out without generating steam. Therefore, implementing the present disclosure solves the problem of steam spraying when the instant heating body outputs high-temperature water, can improve the speed of heating water by the instant heating body and the setting of the maximum temperature, and does not require subsequent addition of a steam separation structure, and can directly discharge the heated high-temperature water, enhancing the usability and good performance of the instant heating body.

[0057] The heating device is provided with a spiral diversion ring in the interlayer between the heating tube and the diversion tube, making the volume inside the heating device smaller. Therefore, the amount of water flowing into the heating device becomes smaller, improving the heating speed of water; and, the spiral heating channel makes the water flow spirally in the heating channel, forming a self-rotating water ring, preventing the water from flowing in a straight line, increasing the contact opportunities between different parts of the water and the heating body, accelerating heat conduction, balancing the temperature of the heating body, avoiding local high-temperature heating points on the heating body, prolonging the service life of the heating body, and also preventing the water from being vaporized, thus not generating steam. At the same time, the self-rotating water ring also accelerates the heat exchange between the water, with a fast temperature rise and small water temperature fluctuation. The spiral heating channel prolongs the heating path, with a fast heating speed and uniform water temperature.

[0058] In addition, since the diversion ring is made of a heat-conducting material and the diversion ring is in contact with the heating body, the heating tube can conduct heat through the spiral diversion ring, increasing the contact area between the heating body and the water and making the water temperature rise quickly. The diversion tube and the diversion ring are arranged in the heating tube, making the volume of the heating channel in the interlayer small. Therefore, the thermal expansion and contraction of the heating device are small, and when the heating stops, the amount of heat overflow water is small.

[0059] According to the following detailed description of the exemplary embodiments with reference to the accompanying drawings, other features and aspects of the present disclosure will become clear. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] Embodiment 1

[0078] Please refer to the attached instruction manual Figure 1 , which shows a longitudinal sectional schematic diagram of the rapid heating element provided by the embodiments of the present disclosure. As Figure 1 shown, the rapid heating element includes:

[0079] A housing 1, the housing 1 includes a water inlet 11 and a water outlet 12;

[0080] A heating element tube 2, the heating element tube 2 is arranged inside the housing 1, and a sandwich for water flow to pass through is formed between the housing 1 and the heating element tube 2;

[0081] A heat-conducting and fluid-conducting body 3, the heat-conducting and fluid-conducting body 3 is arranged in the sandwich, reducing the volume of the sandwich, so that less water enters the sandwich. Therefore, the speed of heating water can be increased. The heat-conducting and fluid-conducting body 3 is axially wound around the outside of the heating element tube 2. Therefore, the heat-conducting and fluid-conducting body 3 conducts the heat generated by the heating element tube 2 to the water flow in the sandwich, and guides the water flow to rotate around the heating element tube 2 and flow to the water outlet 12. The rotation of the water flow helps to increase the contact amount between different water and the heating element tube 2, avoiding the same part of the water being in direct contact with the heating element tube 2 and being continuously heated, so as to form a positive feedback of water vapor and cause the steam spraying problem when discharging high-temperature water;

[0082] As Figure 2 shown, an eddy current spoiler 4 is arranged at a first position of the heating element tube 2. The eddy current spoiler 4 is used to disturb the water flow entering the sandwich, so that the water flow entering the sandwich is in a swirling state. The first position is close to one end where the water inlet 11 of the housing 1 is located. In the embodiments of the present disclosure, a turbine is selected as the eddy current spoiler 4, and the turbine is fixed at the first position on the heating element tube 2. When the water flow passes through the turbine, it is disturbed and forms a swirl, making the heated water temperature more uniform and not easily generating water vapor.

[0083] In the embodiment of the present disclosure, a stainless-steel spring is selected as the heat-conducting and water-conducting body 3. Since the water that does not come into contact with the heating body tube 2 requires heat conduction between water flows, the heating speed is slow and the heated water temperature is uneven. By making the stainless-steel spring in close contact with the heating body tube 2, the heat generated by the heating body tube 2 can be conducted to the water flow faster, making the heating speed of the water faster. The heat-conducting and water-conducting body 3 can also be other heat-conducting materials such as copper, aluminum, and zinc. After the water flow enters the instant heating body, it flows around the heating body tube 2 along the stainless-steel spring in a rotating state to the water outlet of the instant heating body. The rotation of the water flow around the heating body tube 2 increases the contact amount between different water and the heating body tube and the stainless-steel spring, enabling more water in the water flow to be heated and the water temperature to be more uniform, avoiding the problem of steam spraying caused by continuous heating of the water in direct contact with the heating body tube 2. It should be noted that except for the spring, the heat-conducting and water-conducting body can be any other shape that can guide the water flow to rotate around the heating body tube. Therefore, the embodiment of the present disclosure does not limit the material and shape of the heat-conducting and water-conducting body 3.

[0084] In a preferred disclosed embodiment, the housing 1 can be formed by die-casting a high-quality metal aluminum material into a cylindrical shape, and the housing 1 can ensure uniform heat distribution. An inlet 11 is provided at the bottom of the housing 1, and an outlet 12 is provided at the top. The water flow enters the interior of the instant heating body from the inlet 11 at the bottom and directly exits from the outlet 12 at the top after heating is completed.

[0085] In the embodiment of the present disclosure, a turbine is also provided at the second position of the heating body tube 2. When the water flow passes through the turbine, it is disturbed, making the water flow temperature at the outlet 12 uniform. At this time, the water temperature at the outlet is closest to the actual water temperature obtained after the instant heating body is heated. The second position is adjacent to one end where the outlet 12 of the housing 1 is located.

[0086] In the embodiment of the present disclosure, sealing rings are provided on the inlet 11 and the outlet 12, and a temperature sensor is also provided on the outlet 12. To reduce costs, the temperature sensor can be an NTC temperature sensor. The temperature sensor is connected to an external temperature control device to monitor the water temperature at the outlet 12 during the operation of the instant heating body. When the water temperature reaches the preset required temperature, the external temperature control device controls the instant heating body to stop heating. Since a turbine is provided at the outlet 12, the detected water temperature is closer to the actual obtained water temperature, making the detection of the water outlet temperature by the temperature sensor more accurate. Therefore, the accuracy of temperature control of the instant heating body in the embodiment of the present disclosure is also improved.

[0087] Figure 3 The structural schematic diagram of the water treatment device provided according to the embodiment of the present disclosure is shown. Please refer to Figure 3, the water treatment device specifically includes a rapid heating element 101, a temperature setting control 102, and a target water outlet 103, where:

[0088] The rapid heating element 101 is used to heat water.

[0089] The temperature setting control 102 is used to set the temperature of the hot water to be obtained.

[0090] The target water outlet 103 is used to directly discharge the water heated by the rapid heating element.

[0091] Among them, the rapid heating element 101 is the rapid heating element provided by the embodiment of the present disclosure, and this rapid heating element will not cause steam spraying problems when discharging high-temperature water.

[0092] In the embodiment of the present disclosure, the temperature setting control 102 receives the outlet water temperature detected by the temperature sensor of the rapid heating element 101, and controls the rapid heating element to stop heating when the outlet water temperature reaches the preset required temperature. Specifically, since the rapid heating element provided by the embodiment of the present disclosure is used for heating, the water temperature during heating is uniform and no water vapor is generated, and there is no risk of steam spraying when discharging high-temperature water. Therefore, the rapid heating element 101 can heat water to 100 °C, and the maximum temperature at which the temperature setting control controls the rapid heating element 101 to heat can be set to 100 °C. That is to say, the rapid heating element provided by the embodiment of the present disclosure improves the maximum temperature setting of the rapid heating element.

[0093] Furthermore, since the water temperature during heating is uniform and no water vapor is generated, there is no need to set up a water vapor separation structure to separate the water vapor and then discharge the water. The target water outlet can directly discharge the water heated by the rapid heating element.

[0094] Figure 4 The flowchart showing the water treatment method provided by the embodiment of the present disclosure is shown. The water treatment method is applied to the water treatment device provided by the embodiment of the present disclosure according to the above, and specifically includes steps S21 - S24, as follows:

[0095] S21 Open the water inlet of the rapid heating element so that water flows into the interior of the rapid heating element from the water inlet of the rapid heating element.

[0096] S22 Disturb the water flow to form a turbulent flow and enter the interior of the rapid heating element with the turbulent flow.

[0097] In the embodiments of the present disclosure, a turbine is provided at the water inlet of the rapid heating element in the water treatment device. When the water flow passes through the turbine, it is disturbed to form a turbulent flow, and enters the interior of the rapid heating element in a turbulent state. The turbulent state can increase the contact amount between different water and the heating element tube 2 and the heat conduction and heat transfer fluid 3, so that a large amount of water can be heated. Therefore, the temperature rises relatively evenly during the heating process and it is not easy to generate water vapor.

[0098] S23 makes the water flow rotate around the heating element tube and flow to the water outlet;

[0099] In the embodiments of the present disclosure, a stainless steel spring is provided inside the rapid heating element in the water treatment device. After the water flow enters the interior of the rapid heating element, it flows along the stainless steel spring and rotates around the heating element tube of the rapid heating element to the water outlet of the rapid heating element, obtaining heated water. Since the water flow rotates around the heating element tube of the rapid heating element, it avoids the problem that part of the water flow has been in contact with the heating element tube of the rapid heating element and is continuously heated to generate water vapor. By rotating, the contact amount between the water flow and the heating element tube of the rapid heating element is increased, making the water flow temperature rise evenly and avoiding the positive feedback of water vapor formation to cause steam ejection. Therefore, the heated water can reach a very high temperature without reducing the maximum temperature of the rapid heating element. At present, when the outlet water temperature of the rapid heating element is too high, water vapor will be generated to cause steam ejection. Therefore, the maximum temperature of the currently heated rapid heating element cannot be too high, usually only reaching 85 °C.

[0100] S24 discharges the treated water;

[0101] When the target water outlet of the water treatment device is opened, the heated water is directly discharged. Since the rapid heating element of the water treatment device is provided with a heat conduction and heat transfer fluid and a turbine, a large amount of water can be heated evenly during the heating process, and there is no huge temperature difference. Therefore, no water vapor will be generated. Even when the water temperature reaches the maximum temperature of the rapid heating element, no water vapor will be ejected from the target water outlet along with the high-temperature water to cause a safety hazard, and direct discharge can be carried out. Therefore, the rapid heating element does not need to be equipped with a subsequent water vapor separation structure, which is significantly different from the current rapid heating element that adds a subsequent water vapor separation structure to avoid steam ejection when discharging high-temperature water.

[0102] Embodiment 2

[0103] This embodiment is basically the same as Embodiment 1, and the difference lies in:

[0104] Such as Figures 5 - 8As shown in the figure, this embodiment discloses a heating device, which includes a diversion pipe 201, a heating pipe 202, and a diversion ring 203. The heating pipe 202 is sleeved outside the diversion pipe 201, and a channel is formed between the heating pipe 202 and the diversion pipe 201. The inner wall of the heating pipe 202 constitutes a heating body. The diversion ring 203 is arranged between the diversion pipe 201 and the heating pipe 202, and divides the channel into a spiral heating channel 100. The diversion ring 203 is made of a heat-conducting material, and at least a part of the diversion ring 203 is in thermal contact with the heating body and forms a heat-conducting path.

[0105] As Figures 5 - 8 shown in the figure, in this embodiment, the heating device sets a spiral diversion ring 203 in the interlayer between the heating pipe 202 and the diversion pipe 201, which reduces the internal volume of the heating device, so that the water flow entering the heating device becomes smaller, and the heating speed of water is increased; moreover, the spiral heating channel 100 makes the water flow spirally in the heating channel 100 to form a self-rotating water ring, preventing the water from flowing in a straight line, increasing the contact opportunities between different parts of the water and the heating body, accelerating heat conduction, balancing the temperature of the heating body, avoiding local high-temperature heating points on the heating body, prolonging the service life of the heating body, and also preventing the water from being vaporized, so no steam is generated. At the same time, the self-rotating water ring also accelerates the heat exchange between the waters, with a fast temperature rise and small water temperature fluctuations. The spiral heating channel 100 extends the heating path, with a fast heating speed and uniform water temperature.

[0106] In addition, as Figures 5 - 8 shown in the figure, since the diversion ring 203 is made of a heat-conducting material and the diversion ring 203 is in contact with the heating body, the heating pipe 202 can conduct heat through the spiral diversion ring 203, increasing the contact area between the heating body and the water and making the water temperature rise quickly. The diversion pipe 201 and the diversion ring 203 are arranged in the heating pipe 202, making the volume of the heating channel 100 in the interlayer small, so the thermal expansion and contraction of the heating device are small, and when the heating stops, the amount of heat overflow water is small.

[0107] The heating body is configured with a first heat transfer area S1, and the diversion ring 203 is configured with a second heat transfer area S2. The ratio of the sum of S1 and S2 to S1 is not less than 1.1; wherein, the first heat transfer area S1 is the surface area of the heating body in contact with the water, and the second heat transfer area S2 is the surface area of the diversion ring 203 in contact with the water. By setting the diversion ring 203, compared with not setting the diversion ring 203, the heating area of the heating body is significantly increased, and the heating efficiency is improved.

[0108] The diversion ring 203 is made of a metal material to improve heat conduction, facilitate the heat of the heating pipe 202 to be transferred to the water through the diversion ring 203, increase the heating area, and improve the heating speed.

[0109] For the convenience of processing and assembly, the diversion ring 203 is set as a separate component between the diversion pipe 201 and the heating pipe 202.

[0110] In this embodiment, the total volume of the heating channel 100 is 25 cubic centimeters, and at least 9 square centimeters of heat transfer area is configured for each cubic centimeter of volume, so that the heat transfer area per unit volume is relatively large, improving the heating speed.

[0111] As Figure 5 and Figure 6 shown, the heating device further includes a housing 1, a water inlet unit 205 and a water outlet unit 206. The heating pipe 202 is arranged in the housing 1. The water inlet unit 205 is matched with the water inlet end of the heating channel 100, and the water outlet unit 206 is matched with the water outlet end of the heating channel 100. The housing 1 is used for heat preservation to prevent the heat loss of the heating pipe 202, and the housing 1 is also used to protect the heating pipe 202. The water inlet unit 205 has a water inlet 11, and the water inlet 11 is used to connect tap water or purified water. Water flows into the heating pipe 202 through the water inlet 11 of the water inlet unit 205, and after being heated by the heating pipe 202, the water flows out from the water outlet 12 of the water outlet unit 206, and the user obtains the hot water needed at the water outlet 12.

[0112] As Figure 5 and Figure 6 shown, the water inlet unit 205 includes a lower housing 2052, and there is a water inlet cavity on the lower housing 2052. A first diverter 2051 is arranged at the water inlet end of the heating channel 100. A plurality of blades are arranged on the first diverter 2051, and diversion channels are formed between adjacent blades. The diversion channels are respectively communicated with the water inlet cavity and the heating channel 100. While the first diverter 2051 diverts water through the blades, it turbulizes the water to form a self-rotating water ring, preventing the water from flowing in a straight line, disturbing the water before it enters the heating pipe 202, increasing the contact opportunities between different parts of the water and the heating body, accelerating heat conduction, balancing the temperature of the heating body, avoiding the existence of local high-temperature heating points on the heating body, preventing the water from being vaporized, prolonging the service life of the heating body, and at the same time also accelerating the heat exchange between the water, with small water temperature fluctuations.

[0113] As Figure 7 shown, the blades of the first diverter 2051 are inclined, and the inclination direction of the blades of the first diverter 2051 is the same as the rotation direction of the heating channel 100, forming self-rotating water, increasing the contact opportunities between different water and the heating body, accelerating heat conduction, improving the water turbulization effect. At the same time, the self-rotating water also accelerates the heat exchange between the water, with fast and uniform temperature rise. And, the self-rotating water has fast heat conduction, balances the temperature of the heating body, and avoids burning out the heating body due to local high temperature.

[0114] In another embodiment, the blades of the first diverter 2051 are inclined, and the inclination direction of the blades of the first diverter 2051 is opposite to the rotation direction of the heating channel 100 to improve the water turbulization effect.

[0115] As Figure 5and Figure 6 As shown in Figure 6 , the water outlet unit 206 includes an upper housing 2062 which has a water outlet cavity. A second diverter 2061 is provided at the water outlet end of the heating channel 100. A plurality of vanes are provided on the second diverter 2061, and diversion channels are formed between adjacent vanes. The diversion channels are respectively communicated with the water outlet cavity and the heating channel 100. The second diverter 2061 turbulates the heated high-temperature water, enabling the water to be quickly mixed and equalizing the water temperature at the water outlet 12.

[0116] As Figure 7 shown in Figure 7 , the vanes of the second diverter 2061 are inclined, and the inclination direction of the vanes of the second diverter 2061 is opposite to the rotation direction of the heating channel 100, enabling the water to flow out smoothly and reducing the water resistance.

[0117] In another embodiment, the vanes of the second diverter 2061 are inclined, and the inclination direction of the vanes of the second diverter 2061 is the same as the rotation direction of the heating channel 100, improving the water mixing effect and equalizing the water temperature at the water outlet.

[0118] As Figure 8 shown in Figure 8 , the cross-section of the heating channel 100 along the axial direction of the heating tube has a first dimension segment 200 and a second dimension segment 300. The first dimension segment 200 is close to the heating tube 202, and the second dimension segment 300 is located in the middle of the cross-section. The length of the first dimension segment 200 is greater than the length of the second dimension segment 300, forming a narrow middle structure and an open end structure. The open end structure corresponds to the heating element, with a large water flow rate, enabling a larger-sized heating element to heat the water and improving the heating efficiency. The narrow structure has a small water flow rate because it is far from the heating element, so as to equalize the heating.

[0119] As Figure 8 shown in Figure 8 , the guide ring 203 is made of a heat-conducting material. The cross-section of the heating channel 100 along the axial direction of the heating tube is a regular figure, which includes a first straight segment 400, a first arc segment 500, a second straight segment 600, and a second arc segment 700 that are connected end to end in sequence. The first straight segment 400 and the second straight segment 600 are oppositely arranged, and the first arc segment 500 and the second arc segment 700 are oppositely arranged, and the first arc segment 500 and the second arc segment 700 bulge in the direction of approaching each other. Since the guide ring 203 is made of a heat-conducting material, the heat of the heating tube 202 can be transferred to the water in the heating channel 100 through the guide ring 203, enabling the first straight segment 400, the first arc segment 500, and the second arc segment 700 to heat the water simultaneously, increasing the heating area and improving the heating efficiency.

[0120] In this embodiment, forces are applied to both ends of the flow guiding ring 203 in the axial direction of the heating pipe 202 to maintain elastic potential energy. Specifically, the flow guiding ring 203 can be compressed by the water inlet unit 205 and the water outlet unit 206 to keep the elastic potential energy of the flow guiding ring 203. On the one hand, the flow guiding ring 203 is fixed, and on the other hand, the gap between adjacent spirals is kept fixed to prevent the shape of the heating channel 100 from changing and affecting the heating effect. Further, the flow guiding ring 203 can be compressed by the first diverter 2051 and the second diverter 2061 to keep the elastic potential energy of the flow guiding ring 203.
