The utility model provides a pan, refer to fig. 1 and fig. 2, pan includes nested interior pot 1 and outer pot 2, is formed with inclosed intermediate layer chamber Q between interior pot 1 and the outer pot 2, and has accommodated liquid phase transition working medium L in the intermediate layer chamber Q, is equipped with outer hydrophilic structure 21 on the lateral wall of interior hydrophilic structure 11 and/or intermediate layer chamber Q on the inside wall of intermediate layer chamber Q. Except that being equipped with interior hydrophilic structure 11 or being equipped with outer hydrophilic structure 21 on the lateral wall of the intermediate layer chamber Q of pan on the inside wall of the intermediate layer chamber Q of pan promptly, can also be equipped with hydrophilic structure simultaneously on the inside wall of the intermediate layer chamber Q of pan and the lateral wall of intermediate layer chamber Q.

Additionally, the utility model also provides a cooking device, cooking device includes the pan. In particular, the cooking device further comprises a heating element for heating the outer pot 2 of the pot, and generally the heating element heats the bottom of the outer pot 2. Wherein, the heating element can be selected from an electrothermal tube, an electrothermal film or a PTC heating plate. The cooking device may be an electric cooker, an electric pressure cooker, or other cooking device for cooking food materials, but is not limited thereto.

In the utility model, the liquid phase change working medium L is loaded in the closed interlayer cavity Q between the inner pot 1 and the outer pot 2, and the inner side wall of the interlayer cavity Q is provided with the inner hydrophilic structure 11 and/or the outer hydrophilic structure 21 on the outer side wall of the interlayer cavity Q, so the outer pot 2 can heat the liquid phase change working medium L contained in the interlayer cavity Q after being heated and warmed, so as to promote the liquid phase change working medium L to be vaporized into high-temperature steam by being heated and to be diffused in the interlayer cavity Q, and because the inner hydrophilic structure 11 and/or the outer hydrophilic structure 21 have larger affinity to water, the high-temperature steam diffused in the interlayer cavity Q is easily attracted by the inner hydrophilic structure 11 and/or the outer hydrophilic structure 21 and is adsorbed on the inner hydrophilic structure 11 and/or the outer hydrophilic structure 21 and is quickly condensed and reflows, thereby the adverse effect on the gaseous phase change working medium which is continuously generated is reduced, for example, the resistance of the liquid phase change working medium condensed in the interlayer cavity Q to the continuously rising gaseous phase change working medium can be reduced, so that the gas-liquid phase change circulation rate of the phase change working medium is accelerated, and the heat transmission rate of the cookware is greatly improved.

In addition, including hydrophilic structure 11 go up the condensation and through inner hydrophilic structure 11 heat conduction to inner pan 1's inner wall that will carry of high temperature steam, then the inner wall through inner pan 1 heats the edible material of holding in it and cooks, and like this, hydrophilic structure 11 can make high temperature steam adsorb fast to inner pan 1 on and carry out the heat exchange with inner pan 1 through setting up, thereby can make the heat transfer efficiency of pan effectively improve, and then make inner pan 1 rapid heating up, be favorable to accelerating the rate of heating of eating the material, give the better culinary art experience of user. Furthermore, compare including not being equipped with interior hydrophilic structure 11 on pot 1, the utility model discloses in, because be equipped with the interior hydrophilic structure 11 that has great affinity ability to water on pot 1 in, make high-temperature steam be partial to the condensation on the interior pot 1 that is equipped with interior hydrophilic structure 11, thereby make more high-temperature steam adsorbed to interior hydrophilic structure 11 on, like this, can make more heat through interior hydrophilic structure 11 transmit to interior pot 1 and boil in order to eating the material, correspondingly make less heat through outer pot 2 outside diffusion losses, be favorable to promoting the thermal efficiency of pan.

Optionally, when being equipped with outer hydrophilic structure 21 on the lateral wall of intermediate layer chamber Q, in order to guarantee the thermal efficiency of pan, can be equipped with the heat preservation on the outer pot outer wall of outer pot 2 to avoid the heat in the intermediate layer chamber Q to scatter and disappear and promote the heat to the inside transmission of pan to the pan outside through the outer pot outer wall of outer pot 2, effectively promote the heat transfer efficiency of pan.

The inner hydrophilic structure 11 and/or the outer hydrophilic structure 21 have/has a relatively high affinity for water, so the liquid phase change working medium L may be water, a mixture of water and water-soluble liquid such as an ethanol aqueous solution or an ether aqueous solution, or other appropriate types of liquid phase change working media L, and thus the liquid phase change working medium L can be vaporized into high-temperature water vapor after being heated, and the high-temperature water vapor can be condensed into liquid after being precooled. In addition, in order to prevent the liquid phase change working medium L from escaping from the interlayer cavity Q after being vaporized into steam, the interlayer cavity Q is set to be a closed cavity. In order to reduce the vaporization temperature of the liquid phase-change working medium L and further improve the heat transfer efficiency of the cookware, the interlayer cavity Q is preferably set as a vacuum cavity (i.e. the pressure in the interlayer cavity Q is lower than one atmospheric pressure).

The liquid phase change working medium L is positioned at the bottom of the interlayer cavity Q, and when the liquid phase change working medium L is heated and vaporized into high-temperature steam, the high-temperature steam upwards diffuses from the liquid level of the liquid phase change working medium L and flows to the upper part of the outer side peripheral wall of the inner pot 1 through the lower part of the outer side peripheral wall of the inner pot 1. Therefore, the high-temperature steam is not uniformly condensed on the inner hydrophilic structure 11 at different parts of the peripheral wall of the outer side of the inner pot 1, which is not beneficial to the temperature equalizing effect of the pot. In view of this, with reference to fig. 1, the sandwich cavity Q comprises a circumferential sandwich cavity sandwiched between an inner pot circumferential wall and an outer pot circumferential wall, the circumferential sandwich cavity comprising an upper circumferential sandwich cavity and a lower circumferential sandwich cavity, wherein the inner hydrophilic structure 11 preferably comprises an upper inner hydrophilic structure disposed on an inner sidewall of the upper circumferential sandwich cavity and a lower inner hydrophilic structure disposed on an inner sidewall of the lower circumferential sandwich cavity, and an average contact angle of the upper inner hydrophilic structure is smaller than an average contact angle of the lower inner hydrophilic structure. So set up, compare hydrophilic structure in the lower part, hydrophilic structure has bigger affinity ability to water in the upper portion to make high temperature steam change adsorbed to hydrophilic structure in the upper portion on, like this, can make high temperature steam comparatively condense uniformly on the hydrophilic structure 11 in pot 1 different positions in, and then make the pan have better samming effect. Specifically, the average contact angle of the upper internal hydrophilic structure should be not less than 0.1 ° and not more than 5 °. Further, the average contact angle of the lower internal hydrophilic structure should be not less than 3 ° and not more than 15 °.

Further, intermediate layer chamber Q still includes the bottom intermediate layer chamber that forms between interior pot diapire and outer pot diapire, interior hydrophilic structure 11 is still including setting up the hydrophilic structure in the diapire on the inside wall in bottom intermediate layer chamber, hydrophilic structure in the diapire, the average contact angle of hydrophilic structure in hydrophilic structure and the upper portion in the lower part diminishes in proper order, and like this, can make the condensate among the hydrophilic structure in the lower part flow to hydrophilic structure in the diapire fast, and because the average contact angle of hydrophilic structure sets greatly in the diapire (if hydrophilic structure's in the diapire average contact angle is 10 ~ 30 °), make the liquid drop of gathering on the hydrophilic structure in the diapire drop downwards more easily, be favorable to guaranteeing that liquid phase change working medium L carries out vapour-liquid circulation phase transition uninterruptedly in intermediate layer chamber Q.

The inner hydrophilic structure of the bottom wall can be defined as the inner hydrophilic structure which is arranged on the inner side wall of the bottom interlayer cavity and is lower than the bottom area of the liquid level of the liquid phase change working medium when the cookware is not heated. As shown in fig. 1, the height of the pot is H1, the height of the liquid level of the liquid phase change working medium when the pot is not heated from the plane where the lowest point of the bottom of the pot is H2, and the inner hydrophilic structure on the inner side wall of the circumferential interlayer cavity and in the upper area with the height higher than H1/2 is an upper inner hydrophilic structure; the inner hydrophilic structure of the lower area which is arranged on the inner side wall of the upper circumferential interlayer cavity and is lower than H1/2 in height is a lower inner hydrophilic structure; the inner hydrophilic structure on the inside wall of the bottom sandwich chamber and at a height lower than the bottom region of H2 is a bottom wall inner hydrophilic structure. It should be noted that, in addition to dividing the hydrophilic structure 11 into three regions of the upper inner hydrophilic structure, the lower inner hydrophilic structure and the bottom wall inner hydrophilic structure and setting different contact angles, more regions with different contact angles can be set, which is not limited by the present invention; in addition, the specific proportion of the upper inner hydrophilic structure, the lower inner hydrophilic structure and the bottom wall inner hydrophilic structure is divided into the above modes, and the design and the like can be carried out according to the actual shape and the actual application scene of the cookware.

It can be understood by those skilled in the art that the method for measuring the contact angle in the present invention can adopt a general liquid drop angle measurement method known to those skilled in the art, for example, a liquid phase change working medium liquid drop with a standard volume is dropped on the surface of a flat hydrophilic structure by a micro-syringe, and a static liquid drop image of the liquid drop on the surface of the hydrophilic structure is obtained to calibrate the contact angle of the liquid drop in a computer, and the specific operation method is not discussed herein. Of course, other measurement methods may be used, and the present invention is not limited thereto.

Because interior hydrophilic structure 11 can be through attracting high temperature steam and gathering the heat, for making pot 1 be heated evenly in whole, avoid appearing eating the material to press from both sides raw or cook the food taste that obtains and be not good etc. bad situation because of pot 1 is heated less in the part, preferably, interior hydrophilic structure 11 sets up to the inside wall that covers sandwich cavity Q completely, also is equipped with interior hydrophilic structure 11 on the outer wall of pot 1 in promptly. Of course, the inner hydrophilic structure 11 may be provided as a spiral disk on the inner peripheral wall and/or the inner bottom wall of the interlayer cavity Q, but is not limited thereto.

Referring to fig. 3 and 4, the outer side wall of the interlayer cavity Q is provided with the outer hydrophilic structure 21, so that when the heating element heats the liquid phase change working medium L through the outer pot 2 ceaselessly so as to vaporize the liquid phase change working medium L into water vapor, the outer hydrophilic structure 21 positioned at the bottom of the outer pot 2 generates a state of losing liquid water, so that condensate adsorbed to the outer hydrophilic structure 21 positioned at the top of the outer pot 2 can rapidly flow toward the outer hydrophilic structure 21 positioned at the bottom of the outer pot 2, thus effectively avoiding the situation of heat reduction transmitted to the inner pot 1 due to the lack of the liquid phase change working medium L at the bottom of the interlayer cavity Q for vaporization, and being beneficial to ensuring that the pot has higher heat transfer efficiency. In order to ensure that the liquid phase change working medium L continuously carries out vapor-liquid circulation phase change in the interlayer cavity Q, the average contact angle of the outer hydrophilic structure 21 is set to be not less than 0.1 degrees and not more than 30 degrees.

Further, a top rim circumferential seal is formed between the top rim of the circumferential wall of the inner pot 1 and the top rim of the circumferential wall of the outer pot 2, the inner hydrophilic structure 11 extending to the top rim of the circumferential wall of the inner pot 1 is connected with the outer hydrophilic structure 21 extending to the top rim of the circumferential wall of the outer pot 2, and with continued reference to fig. 3 and 4, when the outer pot 2 is heated by the heating element to generate a state of losing liquid water in the outer hydrophilic structure 21 located at the bottom of the outer pot 2, the condensate adsorbed to the inner hydrophilic structure 11 can be caused to flow upward and into the outer hydrophilic structure 21 connected with the inner hydrophilic structure 11, and then the condensate flowing into the outer hydrophilic structure 21 located at the top of the outer pot 2, together with the condensate adsorbed to the outer hydrophilic structure 21 located at the top of the outer pot 2, rapidly flow toward the outer hydrophilic structure 21 located at the bottom of the outer pot 2, so that not only high-temperature steam can be adsorbed to the inner hydrophilic structure 11 more rapidly and exchange heat with the inner pot 1, the heat transfer efficiency of the pot is further improved, and the liquid phase change working medium L can be ensured to have a better vapor-liquid circulation phase change speed in the interlayer cavity Q.

Alternatively, the outer hydrophilic structure 21 may be provided to completely cover the outer sidewall of the interlayer cavity Q. Specifically, the area of the outer hydrophilic structure 21 that covers on the inner wall of outer pot 2 is more, then correspondingly adsorb the volume of the high-temperature steam on the outer hydrophilic structure 21 just more, cause more heat through outer pot 2 outdiffusion loss, therefore, for promoting the thermal efficiency of pan, still can set up outer hydrophilic structure 21 to be equipped with the outer hydrophilic structure of diapire on sandwich cavity Q's the outside diapire, be equipped with many on sandwich cavity Q's the outside perisporium and connect the outer hydrophilic structure of diapire and interior hydrophilic structure 11 and follow the vertical outer hydrophilic structure that the circumference interval was arranged.
