In order that the above objects, features and advantages of embodiments according to the present application may be more clearly understood, embodiments according to the present application will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that features of embodiments according to the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of embodiments according to the present application, however, embodiments according to the present application may be practiced in other ways than those described herein, and therefore the scope of protection afforded by embodiments according to the present application is not limited by the specific embodiments disclosed below.

Some embodiments provided in accordance with the present application are described below with reference to fig. 1-5.

Example 1

As shown in fig. 1, an embodiment according to a first aspect of the present application provides a heating assembly 10 comprising a bladder 100, a water pump 104, a heating device 110, and a turbulator 118.

Specifically, the inner container 100 has a receiving cavity for receiving liquid. The water inlet end of the water pump 104 is communicated with the accommodating cavity, and the water outlet end of the water pump 104 is communicated with the water inlet end of the heating device 110. The heating device 110 is used to heat the liquid flowing from the water pump 104. Both ends of the flow disturbing means 118 are in communication with the water outlet end of the heating means 110 and the receiving chamber, respectively. After the liquid is heated by the heating device 110 to form vapor or vapor-liquid mixture, the vapor or vapor-liquid mixture enters the accommodating cavity through the turbulence device 118, and turbulence is formed on the liquid in the accommodating cavity.

The heating assembly 10 according to the embodiment of the first aspect of the present application includes an inner container 100, a water pump 104, a heating device 110, and a spoiler 118. After the low-temperature liquid flows into the heating device 110 from the accommodating cavity of the inner container 100 through the water pump 104, the low-temperature liquid is heated in the heating device 110 to form high-temperature steam or a steam-liquid mixture. The vapor or vapor-liquid mixture enters the turbulator 118 and then enters the containment chamber. It can be understood that after the steam enters the accommodating cavity of the inner container 100, the steam moves in the accommodating cavity from bottom to top in the form of bubbles, and a turbulent flow effect is generated on the low-temperature liquid in the inner container 100, so that the volatilization of chlorine in the low-temperature liquid is promoted, and the time consumption for chlorine removal is reduced. Meanwhile, high-temperature steam enters the low-temperature liquid, the density of the high-temperature steam is far less than that of the liquid, and the temperature of the high-temperature steam is much higher than that of the liquid, so that the high-temperature steam can quickly exchange heat with the low-temperature liquid while moving in the liquid, the heating speed of the liquid in the liner 100 is increased, and accordingly the time consumption for dechlorination can be reduced.

More specifically, the inner container 100 has a receiving cavity for receiving liquid. The water inlet end of the water pump 104 is communicated with the accommodating cavity. The water pump 104 can drive the liquid to flow, so as to accelerate the heat exchange speed, thereby increasing the temperature rise speed of the liquid in the liner 100. The water inlet end of the heating device 110 is in communication with the water outlet end of the water pump 104 to receive the water pump to deliver the entrained liquid. The heating device 110 only heats a small amount of liquid from the water pump 104, which is beneficial to quickly forming steam, improving the turbulent flow speed and accelerating the dechlorination speed. The turbulent flow device 118 utilizes the turbulent flow effect generated by the steam to promote the volatilization of the chlorine in the liquid, thereby improving the chlorine removal effect in the heating process. The inner container 100, the water pump 104, the heating device 110 and the turbulent flow device 118 are connected into a ring, and steam repeatedly enters the inner container to disturb flow, so that the dechlorination effect is enhanced.

Example 2

As shown in fig. 1, the embodiment according to the first aspect of the present application provides a heating assembly 10, which includes an inner container 100, a water pump 104, a heating device 110, and a flow disturbing device 118, where the number of the flow disturbing devices 118 may be one or more.

The arrangement of the plurality of turbulence devices 118 can increase the turbulence quantity, enhance the turbulence effect, correspondingly improve the dechlorination efficiency and reduce the dechlorination time. It is understood that the cross-sectional area of turbulator 118 needs to be within a certain range of values. Specifically, the sum S of the cross-sectional areas of the plurality of turbulators 118 is 6mm or greater²And is less than or equal to 600mm²。

In some embodiments, the sum of the cross-sectional areas of turbulators 118 is greater than or equal to 6mm². Limiting the sum of the minimum cross-sectional areas of turbulators 118 is beneficial to avoid having too small a vapor bubble to lose the turbulating effect. While the sum of the cross-sectional areas of turbulators 118 is less than or equal to 600mm². The sum of the maximum cross-sectional areas of the turbulent flow devices 118 is limited, which is beneficial to avoiding that the turbulent flow devices 118 are too large and are not easy to seal and install, and can also avoid safety accidents caused by too much steam entering the closed inner container 100 in a short time and too large pressure. In some embodiments, the sum S of the cross-sectional areas of the plurality of turbulators may be further defined as 42mm or greater²Is less than or equal to 168mm². For example 42mm²、50mm²、80mm²、115mm²、128mm²、140mm²、153mm²、168mm²Any one of the above values. It will be appreciated that the cross-sectional area of a single turbulator may be 7mm²、10mm²、12mm²、15mm²、20mm²、28mm²Any one of the equivalent values.

Example 3

As shown in fig. 1, according to another embodiment of the first aspect of the present application, there is provided a heating assembly 10, which includes a tank 100, a preheating tank, a water pump 104, a heating device 110, and a flow disturbing device 118. The turbulator 118 is disposed on the preheat tank. The number of the spoiler 118 may be one or more.

Specifically, the inner container 100 has a receiving cavity for receiving liquid. The water inlet end of the water pump 104 is communicated with the accommodating cavity, and the water outlet end of the water pump 104 is communicated with the water inlet end of the heating device 110. The heating device 110 is used to heat the liquid flowing from the water pump 104. The turbulator 118 is disposed on the preheating slot, which is in communication with the receiving cavity via the turbulator 118. The preheating tank is also communicated with the water outlet end of the heating device 110. After the liquid is heated by the heating device 110 to form steam or a steam-liquid mixture, the liquid firstly enters the preheating tank and then enters the accommodating cavity through the turbulence device 118 to form turbulence to the liquid in the accommodating cavity.

In some embodiments, the sum of the cross-sectional areas of turbulators 118 is greater than or equal to 6mm². Limiting the sum of the minimum cross-sectional areas of turbulators 118 is beneficial to avoid having too small a vapor bubble to lose the turbulating effect. Meanwhile, the sum of the cross sectional areas of the flow disturbing devices 118 is less than or equal to 600mm². Limiting the sum of the maximum cross-sectional areas of turbulators 118 is advantageousThe situation that the turbulent flow device 118 is too large and is difficult to seal and install is avoided, and safety accidents caused by too much steam entering the sealed inner container 100 in a short time and too large pressure can also be avoided. In some embodiments, the sum S of the cross-sectional areas of the plurality of turbulators may be further defined as 42mm or greater²Is less than or equal to 168mm². For example 42mm²、50mm²、80mm²、115mm²、128mm²、140mm²、153mm²、168mm²Any one of the above values. It will be appreciated that the cross-sectional area of a single turbulator may be 7mm²、10mm²、12mm²、15mm²、20mm²、28mm²Any one of the equivalent values.

Through the arrangement of the preheating groove, the steam or the steam-liquid mixture firstly enters the preheating groove, and heat exchange can be carried out between the steam or the steam-liquid mixture and adjacent liquid in the inner container 100 in the preheating groove, so that the liquid in the inner container 100 can be heated, the temperature of the liquid can be increased, and meanwhile, the temperature of the steam or the steam-liquid mixture can be reduced, and the temperature difference between the steam or the steam-liquid mixture and the liquid in the inner container 100 can be reduced. The steam after the temperature difference reduces gets into from vortex device 118 and holds the chamber after, is favorable to reducing the cavitation noise. It can be understood that the larger the temperature difference, the more easily bubbles formed by steam are broken, and the smaller the temperature difference, the less easily bubbles are broken accordingly, thereby reducing cavitation noise.

According to yet another embodiment of the first aspect of the present application, there is provided a heating assembly 10 comprising a bladder 100, a preheating tank, a water pump 104, a heating device 110, and a flow perturbation device 118.

The heating device 110 is used to heat the liquid flowing from the water pump 104. The turbulator 118 is disposed on the preheating slot, which is in communication with the receiving cavity via the turbulator 118. The preheating tank is also communicated with the water outlet end of the heating device 110. After the liquid is heated by the heating device 110 to form steam or a steam-liquid mixture, the liquid firstly enters the preheating tank and then enters the accommodating cavity through the turbulence device 118 to form turbulence to the liquid in the accommodating cavity.

The arrangement of the plurality of turbulence devices 118 can increase the turbulence quantity, enhance the turbulence effect, correspondingly improve the dechlorination efficiency and reduce the dechlorination time.It is understood that the cross-sectional area of turbulator 118 needs to be within a certain range of values. Specifically, the sum S of the cross-sectional areas of the plurality of turbulators 118 is 6mm or greater²And is less than or equal to 600mm²。

In some embodiments, the sum of the cross-sectional areas of turbulators 118 is greater than or equal to 6mm². Limiting the sum of the minimum cross-sectional areas of turbulators 118 is beneficial to avoid having too small a vapor bubble to lose the turbulating effect. Meanwhile, the sum of the cross sectional areas of the flow disturbing devices 118 is less than or equal to 600mm². The sum of the maximum cross-sectional areas of the turbulent flow devices 118 is limited, which is beneficial to avoiding that the turbulent flow devices 118 are too large and are not easy to seal and install, and can also avoid safety accidents caused by too much steam entering the closed inner container 100 in a short time and too large pressure. In some embodiments, the sum S of the cross-sectional areas of the plurality of turbulators may be further defined as 42mm or greater²Is less than or equal to 168mm². For example 42mm²、50mm²、80mm²、115mm²、128mm²、140mm²、153mm²、168mm²Any one of the above values. It will be appreciated that the cross-sectional area of a single turbulator may be 7mm²、10mm²、12mm²、15mm²、20mm²、28mm²Any one of the equivalent values.

The preheating groove is arranged at the bottom of the inner container 100, and the heat exchange of steam or a steam-liquid mixture and liquid is facilitated to be accelerated by utilizing the principle that hot gas rises and cold gas falls, so that the heating efficiency is improved.

In some embodiments, the preheating groove may be formed by the bottom wall of the inner container 100, or may be formed by opening the bottom wall of the inner container 100, and a separate shielding cover 102 is additionally provided to form the preheating groove. Specifically, a part of the bottom wall of the inner container 100 is recessed into the accommodating chamber, and a preheating groove is formed at the recessed position.

As shown in fig. 1 and 4, further, at the opening position, the bottom wall of the inner container 100 is bent toward the bottom, or protrudes outward from the accommodating cavity. Meanwhile, a limiting part 120 is arranged at the opening, and the limiting part 120 is connected with the part, protruding out of the accommodating cavity, of the bottom wall. The isolation cover 102 is disposed on a side of the limiting portion 120 close to the accommodating cavity. By arranging the limiting part 120, the isolation cover 102 can be prevented from being separated from the inner container, so that the working stability and reliability of the isolation cover 102 are ensured.

The isolation cover 102 can temporarily separate the vapor from the liquid, so that the vapor can preheat the liquid and the temperature difference can be reduced.

Example 5

Specifically, the inner container 100 has a receiving cavity for receiving liquid. A preheating groove is arranged on the side wall of the inner container 100. The preheating tank is provided with a flow disturbing device 118. The number of the spoiler 118 may be one or more.

The arrangement of the plurality of turbulence devices 118 can increase the turbulence quantity, enhance the turbulence effect, correspondingly improve the dechlorination efficiency and reduce the dechlorinationChlorine time. It is understood that the cross-sectional area of turbulator 118 needs to be within a certain range of values. Specifically, the sum S of the cross-sectional areas of the plurality of turbulators 118 is 6mm or greater²And is less than or equal to 600mm²。

As shown in fig. 3 and 5, the preheating groove is disposed on the side wall of the inner container 100, and the water pressure is relatively low, which is beneficial to reducing the working pressure of the water pump and improving the air intake efficiency. In addition, the preheating groove is arranged on the side wall of the inner container 100, so that the installation and maintenance are convenient.

In some embodiments, the preheating groove may be formed by a sidewall of the inner container 100. Specifically, a part of the side wall of the inner container 100 is recessed into the accommodating chamber, and a preheating groove is formed at the recessed position. According to the structure, the preheating groove and the inner container are integrally formed, and the structure is stable. Turbulator 118 is a through hole disposed in a recessed location.

The heating assembly 10 further includes an exhaust valve 112, the exhaust valve 112 being in communication with the preheating tank and enclosing a semi-enclosed space 116.

Example 6

As shown in fig. 1, according to yet another embodiment of the first aspect of the present application, there is provided a heating assembly 10 including a bladder 100, a preheating tank, a water pump 104, a heating device 110, an exhaust valve 112, and a turbulator 118. The turbulator 118 is disposed on the preheat tank. The number of the spoiler 118 may be one or more.

The exhaust valve 112 is disposed at the notch position of the preheating bath. The preheat bath and vent valve 112 enclose a semi-enclosed space 116. Vent valve 112 is opened and steam enters semi-enclosed space 116. The exhaust valve 112 is closed, and the steam cannot enter the semi-closed space, and cannot enter the accommodating cavity. By the arrangement of the exhaust valve 112, whether the steam enters the accommodating chamber or not can be freely controlled. In addition, by adjusting the opening of the exhaust valve 112, the amount of steam entering the accommodating chamber can also be controlled.

It will be appreciated that the volume of the semi-enclosed space 116 cannot be too large to avoid reducing the effectiveness of removing cavitation noise. The semi-enclosed space 116 cannot be too small to avoid too small an amount of steam that would reduce the chlorine removal effect. In some embodiments, the volume V of the semi-enclosed space 116 and the bladder volume V₀The ratio of the two is greater than or equal to 0.001 and less than or equal to 0.05. I.e. 0.001. ltoreq. V/V₀Less than or equal to 0.05. Further, V/V₀Greater than or equal to 0.0025 and less than or equal to 0.01. For example, V/V₀The average particle diameter is any of 0.0025, 0.0028, 0.0035, 0.0048, 0.0056, 0.0067, 0.0072, 0.008, 0.0091, 0.0099, 0.01, and the like.

In some embodiments, the volume of the semi-enclosed space 116 is set to 2cm³To 100cm³In the meantime. For example 2cm³、5cm³、15cm³、30cm³、35cm³、40cm³、60cm³、75cm³、80cm³、90cm³、100cm³Any one of the above values.

Example 7

On the basis of any one of the above embodiments, the water inlet end of the water pump 104 is arranged at the bottom of the inner container 100.

The water inlet end of the water pump 104 is arranged at the bottom of the inner container 100, so that the water pressure at the bottom can be utilized, the difficulty of pumping water by the water pump 104 is reduced, energy is saved, and consumption is reduced. In addition, generally speaking, the liquid with lower temperature is located at the bottom, and therefore, by arranging the water inlet end of the water pump 104 at the bottom of the inner container 100, the liquid with lower temperature in the accommodating cavity is favorably pumped into the heating device 108 for heating, so that the heating speed of the liquid in the entire accommodating cavity is increased.

In other embodiments, the water inlet end of the water pump 104 is not limited to be disposed at the bottom of the inner container 100, but may be disposed on the sidewall of the inner container 100. In this way, the processing and sealing arrangement of the inner container 100 is facilitated. The water inlet end is properly higher than the bottom of the inner container 100, which is also beneficial to avoiding water leakage during assembly and disassembly.

As shown in fig. 2, it can be understood that the distance H from the water inlet end of the water pump 104 to the bottom of the liner 100 is limited to a certain range. Due to the different sizes of the inner container 100, the total height H of the side wall of the inner container is determined by limiting the distance H from the water inlet end of the water pump 104 to the bottom of the inner container 100₀The ratio between the two limits the size of H. In particular, the ratio H/H is defined₀Greater than zero and less than or equal to 0.26. For example the ratio H/H₀Is any one of values of 0.05, 0.06, 0.07, 0.079, 0.088, 0.1, 0.12, 0.15, 0.158, 0.18, 0.20 and 0.26.

In a further embodiment, the ratio H/H is defined₀Greater than 0.079 and less than or equal to 0.158.

The distance H from the water inlet end of the water pump 104 to the bottom of the inner container 100 and the total height H of the side wall of the inner container 100 are limited₀The ratio range therebetween is favorable for avoiding that the water inlet end of the water pump 104 is higher than the liquid level in the accommodating cavity and cannot pump water due to the overlarge distance H.

In some embodiments, the distance from the water inlet end of the water pump 104 to the bottom of the liner 100 can be further limited to 15mm to 30 mm. For example, the distance is any one of 15mm, 18mm, 20mm, 22mm, 25mm, and 30 mm.

In any of the above embodiments, the heating assembly 10 further includes a controller 106, a temperature sensor 114. The temperature sensor 114 is used to detect the temperature of the liquid in the accommodating chamber of the inner container 100. The temperature sensor 114 is electrically connected to the controller 106, and the controller 106 is electrically connected to the water pump 104 and the heating device 108. The temperature sensor 114 is arranged to detect the liquid temperature, so that the controller 106 can flexibly control the operation of the heating device 108 and the water pump 104 according to the liquid temperature, thereby improving the working efficiency or reducing the energy consumption. For example, when the temperature sensor 114 detects that the liquid temperature is above 98 ℃, or detects that the liquid temperature has not changed for a certain period of time, for example, 30 seconds, it is determined that the liquid in the inner container has boiled, and there is no need to continue heating. The operation of the heating device 108 and the water pump 104 may be stopped at this time to avoid wasting energy. Of course, the threshold for the duration judgment that the liquid temperature is kept constant may be 30 seconds, and may also be other time periods, such as 40 seconds, 1 minute, 20 seconds, and so on.

The temperature sensor 114 may be disposed at the bottom of the inner container 100, or may be disposed on a side wall of the inner container 100.

In any of the above embodiments, the heating assembly 10 further comprises a safety valve 110. A relief valve 110 is provided on the heating device 108. When the pressure at the heating device 108 is high, the safety valve 110 can be opened to release the pressure, so that the safety of the operation of the heating device 108 can be improved.

Example 8

According to an embodiment of a second aspect of the present application, there is provided a heating apparatus comprising a housing and a heating assembly 10 as described above in any one of the embodiments of the first aspect. The heating assembly 10 is disposed within the housing.

In this embodiment, the heating apparatus includes the heating assembly 10 of the above embodiment, so as to have all the beneficial effects of the above embodiment, which will not be described herein again. The housing is configured to provide protection to the heating assembly 10 therein from external interference.

Example 9

The heating assembly 10 according to one embodiment of the present application includes a bladder 100, a semi-enclosed space 116, a turbulator 118, a shield 102, a water pump 104, a controller 106, a heating device 108, a relief valve 110, a vent valve 112, and a temperature sensor 114.

Specifically, the inner container 100 contains a liquid. Taking tap water as an example, the water inlet end of the water pump 104 is connected with the inner container 100. The water outlet end of the water pump 104 is connected to a heating device 108. The heating device 108 heats the low-temperature water into steam or a mixture of hot water and steam, and then the steam enters the inner container 100. The steam or the mixture of the hot water and the steam heats the low-temperature water in the inner container 100 and generates a turbulent flow effect. The exhaust valve 112 is connected with the bottom or the side wall of the inner container 100, and the steam in the exhaust valve 112 does not directly enter the inner container 100, but enters a semi-closed space 116 first, and then enters the inner container 100 through a turbulent flow device 118 communicated with the semi-closed space 116, so that the water in the inner container 100 is heated while a turbulent flow effect is generated, and the volatilization of chlorine in the tap water is promoted.

Specifically, the semi-enclosed space 116 may be defined by the bottom/side wall of the inner container 100 and the exhaust valve 112, or may be defined by the inner container 100, the isolation cover 102 and the exhaust valve 112. In any case, the semi-enclosed space 116 is in communication with the housing of the bladder 100 by the flow perturbation means 118. The purpose of this design is: steam temperature is higher, directly gets into inner bag 100, and is great with liquid temperature difference in the inner bag 100, can produce great cavitation noise, nevertheless gets into semi-enclosed space 116 earlier, can improve the temperature of water to the water heating in this space fast, reduces with the difference in temperature of steam to greatly reduced cavitation noise, and this enclosed space can play certain isolation effect to the noise.

The heating device 108 is connected with a safety valve 110 besides an inlet/outlet channel, and can exhaust and release pressure to play a role in protection when the pressure in the pipeline is too high under abnormal conditions.

The bottom of the inner container 100 is provided with a temperature sensor 114, and when the water temperature is detected to be more than 98 ℃ or not changed for more than 30 seconds, the water is considered to be boiled, and a temperature signal is transmitted to the controller 106 so as to stop heating.

It can be understood that the hot steam generated by the heating device 108 heats the tap water, and the turbulent flow effect generated by the steam promotes the volatilization of chlorine in the tap water while the heating effect is achieved, so that the chlorine removal effect in the water boiling process is improved. The semi-enclosed space 116 cannot be too large in volume to have the effect of reducing cavitation noise.

In this embodiment, the connection position of the water pump 104 and the inner container 100 may be a bottom or a side wall, but when the water pump 104 is connected to the side wall, the distance between the water inlet end of the water pump 104 and the bottom of the inner container 100 is defined as 0 < H < 50mm, preferably 15mm < H < 30 mm.
