Applying mode, the present invention is further described in detail.It should be noted that in the absence of conflict, the implementation of the application
Feature in example and embodiment can be combined with each other.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, still, the present invention may be used also
To be implemented using other than the one described here other modes, therefore, protection scope of the present invention is not by described below
Specific embodiment limitation.
Referring to heating vessel described in Fig. 1 and Fig. 2 description according to some embodiments of the invention.
As depicted in figs. 1 and 2, heating vessel includes: vessel 10, heating component 30 and coating 50.
Specifically, vessel 10 has the accommodating chamber 101 for accommodating liquid；Heating component 30 is for heating accommodating chamber
Liquid in 101；Coating 50 is formed on the inner wall of vessel 10, and coating 50 with a thickness of d, the surface scratch of coating 50

H。
The ratio between surface scratch hardness h of heating vessel provided by the invention, the thickness d of coating 50 and coating 50 exists
Between 0.56 μm/H~50 μm/H, on the one hand, the ratio both avoided is too small, i.e. the thickness d of coating 50 is too small or coating
50 surface scratch hardness h is excessive, leads to that coating 50 is softer, not wear-resisting, easy to damage or coating 50 is more crisp, is not durable, and influences
The case where service life and influence noise reduction effect of coating 50, occurs；On the other hand, the ratio for avoiding the two is excessive, i.e. coating
The surface scratch hardness h of the excessive perhaps coating 50 of 50 thickness d is too small to cause 50 adhesive force of coating not strong, easy to fall off or apply
The case where layer 50 is softer, not wear-resisting, influences the service life of coating 50 and influences noise reduction effect generation；Thus, rationally setting applies
The thickness d of layer 50 and the ratio between the surface scratch hardness h of coating 50, are detached from after capable of better ensuring that bubble parameters to size appropriate
Coating 50 reduces the noise that heating vessel generates in heating liquid process, while ensure that the use of coating 50 is reliable
Degree, extends the service life of product, to increase the competitiveness of product in market.
In the above-mentioned technical solutions, the shape of heating vessel ontology 10 can be varied, 10 side wall of vessel
It can be with bottom integrally formed, be also possible to assembly welding together；Its material can also be that aluminium closes in addition to stainless steel
The materials such as gold, titanium alloy, copper can choose suitable material and carry out spray treatment；It is defended in addition, the material of coating 50 meets food
It is raw to require, and can long-term 150 DEG C of heatproof or more, the short time can be 260 DEG C of heatproof or more, can be organic coating, ceramic coating
Etc.；Moreover, coating 50 has adhesion well to vessel 10；Finally, the corrosion resistance and good of coating 50, kitchen are common
Oil, salt, sauce, vinegar, tea etc. it will not be damaged.
In addition, it will be appreciated by those skilled in the art that the mode of " formation " of the application meaning includes but is not limited to: molten
It burns, spraying, vapor deposition and diffusion, low-temperature bake, electrochemical process, sol-gel and the original position modes such as reaction in-situ.Example
Such as, coating can be formed on the inner wall of vessel 10 by any or combinations thereof in these modes.
Based on the above-mentioned technical proposal, in the present invention in a specific embodiment, heating vessel ontology 10, which has, to be contained
The coating 50 of fluorine；In the present invention in another specific embodiment, coating 50 of the heating vessel ontology 10 with ceramics.
In one embodiment of the invention, the thickness d of coating 50 is 5 μm≤d≤50 μm, the surface scratch hardness of coating
H is 1H < h≤9H, specifically, 15 μm≤d≤30 μm, 2H≤h≤8H.And the surface scratch of the thickness d of coating 50 and coating 50
The ratio relation of hardness h are as follows: 1.87 μm/H≤d/h≤15 μm/H.
In one particular embodiment of the present invention, the thickness d of coating 50 is 20 μm, the surface scratch hardness h of coating 50
For 3H.
In the present invention in another specific embodiment, the thickness d of coating 50 is 30 μm, the surface scratch hardness of coating 50
H is 6H.
In this embodiment, the thickness d of coating 50 is 15 μm≤d≤30 μm, on the one hand, if the thickness d of coating 50 is less than
15 μm, then coating 50 is softer, not wear-resisting, easy to damage, influences the normal use of coating 50, prevents it from reaching noise-reducing effect；
On the other hand, if the thickness d of coating 50 is greater than 30 μm, the adhesive force of coating 50 is not strong, is easy to fall off, and leverages coating 50
Service life and noise-reducing effect, that is, ensure that the service life of product, to increase the competitiveness of product in market.
Experimental data can obtain, and when 5 μm of d <, coating 50 is too thin, it is easy to wear, and its noise-reducing effect is general, probably
For 1-3dB；When 5 μm≤d≤50 μm, the thickness d of coating 50 is moderate, and adhesive force is stronger, has preferable noise-reducing effect,
About 3-12dB；When 50 μm of d >, coating 50 is too thick, and adhesive force is poor, is easy to fall off, and noise-reducing effect is about at this time
12dB.Therefore, in order to guarantee coating 50 heat-transfer effect, noise-reducing effect and performance not easy to fall off well, the thickness of coating 50
Degree d needs to meet 5 μm≤d≤50 μm, it is preferable that 15 μm≤d≤30 μm.In addition, working as the surface scratch hardness h < 1H of coating 50
When, the coating 50 is relatively soft, and wear-resisting property is poor；As the surface scratch hardness h > 1H of coating 50, the coating 50 is harder, resistance to
It is good to grind performance；It is therefore preferred that 2H≤h≤8H.
In addition, the thickness d of coating 50 and the ratio between the surface scratch hardness h of coating 50 be between 1.87 μm/H~15 μm/H,
On the one hand, the ratio both avoided is too small, i.e. the thickness d of coating 50 is too small or the surface scratch hardness h of coating 50 is excessive,
Lead to that coating 50 is softer, not wear-resisting, easy to damage or coating 50 is more crisp, is not durable, influences the service life and influence of coating 50
The case where noise-reducing effect, occurs；On the other hand, the ratio for avoiding the two is excessive, i.e. the thickness d of coating 50 is excessive or applies
The surface scratch hardness h of layer 50 is too small, leads to that 50 adhesive force of coating is not strong, easy to fall off or coating 50 is softer, not wear-resisting, influences
