The following specific embodiments may be optionally combined with or replaced by each other according to practical situations, and the same or similar concepts or processes may not be described in detail in some embodiments.

The utility model provides a boiling water a kind of deep pot, including inner bag 1, the outer bottom surface of inner bag 1 is equipped with the heater and prevents the temperature controller of dry combustion method, as shown in fig. 1 to fig. 3, the outer bottom surface of inner bag 1 has the temperature sensing area 100 who supplies the temperature sensing element temperature measurement of temperature controller, the interior bottom surface of inner bag 1 is equipped with the hydrophobic coating 11 that the spraying formed, the interior bottom surface of inner bag 1 still is equipped with the interval 12 of making an uproar that falls that forms through laser engraving after hydrophobic coating 11 spraying forms, the interval 12 of making an uproar falls separates into the polygon structure 111 of a plurality of alternate separations with hydrophobic coating 11, there is the overlap at least two polygon structure 111 and the projection of temperature sensing area 100 on the interior bottom surface of inner bag 1.

The utility model discloses an interior bottom surface spraying at inner bag 1 forms hydrophobic coating 11, be favorable to the bubble to produce the back and remove on inner bag 1's interior bottom surface, thereby assemble into the bleb from the bleb, can effectively avoid the bleb to break and produce great noise too early, and because the bleb inside does not have water, the heater belongs to the condition of local dry combustion method to the hydrophobic coating 11 continuous heating that is covered by the bleb, consequently, avoid the too big hydrophobic coating 11 that leads to of bubble to appear local dry combustion method, utilize and fall interval 12 of making an uproar and separate into a plurality of alternate polygonal structure 111 with hydrophobic coating 11, the bleb that the bleb assembles the formation can break after meeting interval 12 of making an uproar falls, thereby avoid the bleb's volume too big, effectively avoid hydrophobic coating 11 to appear local dry combustion method, hydrophobic coating 11 is difficult for droing, be favorable to improving hydrophobic coating 11's life-span, in addition the water pot can experience cold and hot alternate process repeatedly in the use, hydrophobic coating 11 is cut apart into a plurality of polygonal structure 111 after, single polygonal structure 111 area diminishes, the in cold and hot in turn in-process that produces diminishes, the internal stress that further drops, the risk that drops is reduced. If a certain polygonal structure 111 covers the projection of the temperature sensing area 100 on the inner bottom surface of the inner container 1, when the temperature in the range of the polygonal structure 111 is too high, the temperature controller is mistakenly detected to be dry-burned and jump off, and the normal use of a user is affected, therefore, in order to effectively avoid the situation, at least two polygonal structures 111 are specially designed to be overlapped with the projection of the temperature sensing area 100 on the inner bottom surface of the inner container 1, so that in the range corresponding to the temperature sensing area 100, bubbles experience a process of gradually increasing and finally breaking, because the process is short, water can be in contact with the hydrophobic coating 11 immediately after the bubbles break, the temperature of the temperature sensing area 100 is reduced, the situation that the temperature controller is mistakenly detected to jump off for dry burning can be effectively reduced, and the user is ensured to obtain good use experience.

In general, the width W of the noise reduction interval 12 is selected to be 0.05-1 mm, and the noise reduction effect is good. Taking a water boiler with a heater power of 1500W and a rated capacity of the inner container 1 of 1.5L as an example, a comparison experiment is performed under the conditions that the side lengths of polygonal structures 111 (all regular hexagons with equal side lengths) are unchanged and the W is changed, the width W of the noise reduction interval 12 is selected from the values in the above-mentioned interval, the noise can be reduced to 50-60 dB, and it can be known that the smaller the W is, the better the noise reduction effect is, for example, when the side lengths L of the polygonal structures 111 are 6mm, and the W are 1mm, 0.5mm, 0.25mm and 0.15mm, as can be seen from fig. 4 to 7, in the whole water heating process, except for the case that the larger noise appears momentarily at the beginning of heating and at the end of water boiling, in the middle-stage continuous heating process with longer time, the measured noise respectively does not exceed 60dB, 58dB, 56dB and 54dB, and the whole noise reduction effect is still more obvious. Therefore, if W is too large, the noise becomes significantly large, and the noise reduction effect becomes insignificant, but if W is too small, the process is difficult to realize, and the production cost greatly increases, and it is needless to say that it is not excluded that smaller W can be processed at lower cost with the development of the process technology in the future. In addition, the material of the hydrophobic coating 11 may be ceramic or teflon, and from experimental conditions, the noise reduction effect of the ceramic coating (refer to fig. 4 and 5) is more obvious than the noise reduction effect of the teflon coating (refer to fig. 6 and 7), especially in the initial stage of heating, the noise of the water boiler provided with the ceramic coating is lower, and the noise of the water boiler provided with the teflon coating is reduced from a high point when water is boiled.

In order to ensure that the air bubbles will break in time after encountering the noise reduction space 12, the depth H of the noise reduction space 12 may be selected to be larger than the thickness B of the hydrophobic coating 11, i.e. the hydrophobic property of the noise reduction space 12 is low, the viscosity with water increases, and a force generated between each other can cause the air bubbles to break in time.

Through another comparison experiment, namely W is unchanged, the side length L of the polygonal structure 111 (both are regular hexagons) is changed to measure noise, as shown in fig. 8 to 10, W is fixed to be 0.5mm, L is selected to be 2mm, 4mm, 6mm (the noise experiment result of L =6mm refers to fig. 5), 8mm and the like, when L is smaller, the noise reduction effect is not very obvious (the maximum noise is larger), and when L is larger, although the noise reduction effect is good, the early jump situation can occur, namely water is not boiled, the side length is firstly jumped off, therefore, a proper L size is selected, for example, the L of the polygonal structure 111 is 4-7 mm, the noise reduction effect is ensured, and meanwhile, the early jump of the temperature controller can be avoided. From a principle analysis, it is also possible to obtain the same structure, and if L is too small, it is difficult to form large bubbles, and small bubbles are broken with little time to cause an increase in noise, and if L is too large, the area of the polygonal structure 111 is increased, and local dry burning is likely to occur, and early jumping is likely to occur.

In order to make L and W reasonable and cooperate with each other to reduce noise and prevent early jump, the ratio of the side length L of the polygonal structure 111 to the width W of the noise reduction interval 12 may be selected to be not less than 20.

The polygonal structure 111 includes a regular hexagonal structure. Also, triangle, quadrangle, pentagon, etc. are common, and the hydrophobic coating 11 can be formed by combining polygonal structures 111 with different numbers of sides and different shapes. In the above experimental embodiment, the polygonal structures 111 are regular hexagonal structures, and the side lengths of all the regular hexagonal structures are equal, and the widths of all the noise reduction spaces 12 are equal, and the hydrophobic coating 11 is honeycomb-shaped as observed by naked eyes, so that the laser engraving is easy, and the production cost is low.

Referring to fig. 2, the outer bottom surface of the liner 1 has a heating region 101 for installing and heating a heater, i.e. a region between two larger dotted circles, and the heating region 101 belongs to a heat source and has the highest temperature, so that the area of the hydrophobic coating 11 can be selected to be larger than that of the heating region 101 and cover the heating region 101, thereby ensuring the noise reduction effect.

In one embodiment, the liner 1 can be selected to be an integrally formed structure, so that the structure integrity is good, the strength is high, and the service life is long. In another embodiment, the inner container 1 may also include a container body and a bottom plate, the container body and the bottom plate are integrally installed, the hydrophobic coating 11 is disposed on the upper surface of the bottom plate, and the heater is fixed on the lower surface of the bottom plate.

In one embodiment, the heater comprises a heating plate fixed on the outer bottom surface of the inner container 1 and a heating pipe fixed on the lower surface of the heating plate, and the heating plate is generally an aluminum plate and has good and uniform heat-conducting property.

In addition to the above preferred embodiments, the present invention has other embodiments, and all other embodiments obtained by those skilled in the art without any creative work belong to the scope of the claimed invention.
