The application is described below with reference to specific embodiments in conjunction with the following drawings:

the utility model provides an interior pot and domestic appliance who has this interior pot, as shown in fig. 1 to fig. 13, this interior pot 100 includes:

an inner pot body 110;

a temperature sensor 120 disposed on the inner wall 111 of the inner pot body 110; and (c) a second step of,

and a conductor 130 disposed on the inner pot body 110 and connected to the temperature sensor 120.

As shown in fig. 14 to 18, the home appliance includes: the inner pot 100, the outer pot 200 for accommodating the inner pot 100, and the pot cover 300 covering the inner pot 100 and the outer pot 200.

The interior pot 100 that the above-mentioned embodiment of this application provided, the cavity of interior pot body 110 is used for the holding to eat the material as cooking the chamber, inner wall 111 of pot body 110 including through setting up temperature sensor 120, temperature sensor 120 can directly survey the temperature of culinary art intracavity, and through conductor 130 with the outside transmission of inner wall 111 of interior pot body 110 of temperature signal follow, it is the temperature of culinary art intracavity to react, this temperature measurement mode does not receive the influence of heating methods and interior pot 100 structure to the temperature measurement, can improve temperature measurement's accuracy, effectively avoid the technical problem that the temperature control precision is low because temperature measurement error leads to.

In this application, the inner wall 111 of the inner pot body 110 refers to a wall surface forming a cooking cavity inside the inner pot body 110, and includes a bottom wall 1112 and a side wall 1111.

As a preferred embodiment, as shown in fig. 10, the temperature sensor 120 is disposed on the bottom wall 1112 of the inner wall 111.

Further, the temperature sensor 120 is disposed at the lowest position of the bottom wall 1112, or at a position close to the lowest position. When the bottom wall 1112 of the inner pot body 110 protrudes toward the outer wall 113, the center of the bottom wall 1112 of the inner pot body 110 is the lowest position of the bottom wall 1112. When the bottom wall 1112 of the inner pan body 110 is recessed toward the inner wall 111, the connection position of the bottom wall 1112 and the side wall 1111, or the position close to the side wall 1111, is the lowest position of the bottom wall 1112. Due to the design, the liquid in the inner pot body 110 is accumulated at the lowest position of the bottom wall 1112 due to the action of gravity and further contacts with the temperature sensor 120, and the detection accuracy of the temperature sensor 120 is improved. And only a small part of liquid is needed, the temperature sensor 120 can also accurately acquire the temperature of the liquid. In other embodiments, the temperature sensor 120 is disposed on the bottom wall 1112 at a position avoiding indirect contact with the heater, thereby avoiding interference of the temperature sensor 120 by the heater resulting in inaccurate measured temperature data.

As another alternative, the temperature sensor 120 is disposed on the sidewall 1111 of the inner wall 111. Further, the temperature sensor 120 is disposed at the lowest position of the side wall 1111, or at a position close to the lowest position. Preferably, the temperature sensor 120 is disposed at the middle lower portion of the side wall 1111, and may be less than one-half of the height of the inner pot body 110, and further preferably, may be less than one-fourth of the height of the inner pot body 110. The temperature sensor 120 is disposed at a lower position of the sidewall 1111, so that even a small amount of food in the inner pot body 110 can be directly contacted with the temperature sensor 120, and the temperature sensor 120 can directly measure the temperature of the food in real time and transmit the temperature signal to the outside through the conductor 130.

In the above embodiment, compared to the conventional temperature measuring method in which the temperature sensor 120 is disposed on the lid 300, the inner pot 100 of the present application can measure the temperature of the food before the food generates no steam, and has a characteristic of measuring the temperature of the food more realistically; simultaneously, compare in the outside of pot body 110 including traditionally setting up temperature sensor 120, the temperature measurement mode of the inside food temperature of pot body 110 is calculated to outer wall 113 temperature through pot body 110 in the survey, this application makes temperature sensor 120 direct and food contact, avoid heating methods and interior pot body 110 self temperature to temperature sensor 120's influence, can more accurately react the food temperature in the pot body 110, make the food temperature that records more accurate, and then improve accuse temperature precision, reduce accuse temperature error.

As an alternative embodiment, as shown in fig. 4, the inner pot 100 further comprises an inner conductive connecting end 140 disposed at the rim 112 or the outer side of the inner pot body 110 and connected with the conductor 130. Accordingly, as shown in fig. 14 to 18, the household appliance of the present application further includes an outer conductive connection terminal 230 disposed at a position of the outer pot 200 or the pot cover 300, where the outer conductive connection terminal can be abutted against the inner conductive connection terminal 140. It is found that the control main board of the household electrical appliance is generally disposed on a component other than the inner pot body 110, for example, the control main board is disposed on the outer pot 200, or may be disposed on the pot cover 300. The main reason for the conventional arrangement of the temperature sensor 120 at the outer side of the inner pot body 110 or the pot cover 300 is that the inner pot body 110 is self-integrated independently of the household appliance, and the inner wall 111 of the inner pot body 110 is difficult to be effectively connected with the control main board to transmit the temperature signal. In the present application, the temperature sensor 120 is connected to the inner conductive connection end 140 through the conductor 130, and the inner conductive connection end 140 is disposed at the edge 112 or outside of the inner pot body 110; accordingly, the outer conductive connection terminal 230 is disposed at a position where the outer pan 200 or the pan cover 300 can be in contact with the inner conductive connection terminal 140, and the outer conductive connection terminal 230 is connected to the control main board. When placing interior pot 100 in outer pot 200 or after covering pot cover 300, interior conductive connection end 140 can form the connection with outer conductive connection end 230 butt each other, thereby make temperature sensor 120 loop through conductor 130, interior conductive connection end 140, outer conductive connection end 230 forms effectual signal connection with the control mainboard, thereby transmit the temperature signal who detects to the control mainboard, the control mainboard can obtain the food temperature in the interior pot body 110 in real time, thereby can detect according to this fact, accurate food temperature carries out more accurate control to the culinary art procedure. In this embodiment, the inner conductive connecting end 140 and the outer conductive connecting end 230 can be connected conveniently and quickly, and cannot bring inconvenience to taking the inner pot body 110, so that the temperature signal is transmitted from the inner wall 111 of the inner pot body 110 to the outside, and the technical problem that the temperature sensor 120 is arranged on the inner side of the inner pot body 110 and cannot be connected with a control main board positioned on the outer side of the inner pot body 110 is solved.

In the above embodiment, optionally, the control main board is a constituent structure of the outer pan 200, is disposed on the outer pan 200, and is connected to the outer conductive connecting end 230 of the outer conductive connecting end 230 through a wire. When the inner pot body 110 is placed in the outer pot 200, the inner conductive connection end 140 abuts against the outer conductive connection end 230, so that the temperature signal can be transmitted from the inner pot 100 to the control main board.

In other embodiments, the control main board is a constituent structure of the outer pot 200 and is disposed on the outer pot 200, and the outer conductive connecting terminal 230 connected with the control main board is disposed at the edge 112 of the pot cover 300, and when the pot cover 300 is covered on the inner pot 100, the outer conductive connecting terminal 230 can abut against the inner conductive connecting terminal 140 to form a conductive connection.

In other embodiments, the control main board may also be a component structure of the pot cover 300, and is disposed on the pot cover 300, and accordingly, the outer conductive connecting end 230 is disposed at the edge 112 of the pot cover 300, and when the pot cover 300 is covered on the inner pot 100, the outer conductive connecting end 230 may abut against the inner conductive connecting end 140 to form a conductive connection.

As an alternative embodiment, as shown in FIG. 1, the temperature sensor 120 is a thin film thermocouple. The film thermocouple has the advantages of simple structure, convenient manufacture, wide measuring range, high precision, small inertia, convenient output signal remote transmission and the like. Moreover, the film thermocouple is an active sensor, and an external power supply is not needed during measurement, so that the film thermocouple is very convenient to use. The principle of the thin-film thermocouple is that two different conductors/semiconductors A and B form a loop, two ends of the conductors/semiconductors A and B are connected with each other, when the temperatures of two junctions are different, one end is T, called a working end or a hot end, and the other end is T0, called a free end, a reference end or a cold end, an electromotive force is generated in the loop, the direction and the magnitude of the electromotive force are related to the temperature difference between the conductors/semiconductors forming the loop and the two junctions, the phenomenon is called a thermoelectric effect, the loop formed by the two conductors/semiconductors is called a thermocouple, the two conductors/semiconductors are called thermodes, and the generated electromotive force is called a thermoelectric potential. When the materials of the two thermal electrodes of the thermocouple are fixed, the thermoelectromotive force is the function difference of the temperatures T and T0 of the two junctions, a certain thermoelectromotive force corresponds to a certain temperature, and the purpose of measuring the temperature can be achieved only by measuring the thermoelectromotive force.

As shown in fig. 1 and 8 to 10, in this embodiment, the thin-film thermocouple is formed on the inner wall 111 of the inner pot body 110, which may be the bottom wall 1112 of the inner pot body 110 or the side wall 1111 of the inner pot body 110, by spraying, and is attached to the inner wall 111 of the inner pot 100 in a thin film, so that the interference of an external heating device on the temperature measurement of the thin-film thermocouple can be avoided, and the inner pot body 110 can be cleaned and used conveniently.

Optionally, the thin-film thermocouple is formed by spraying a positive electrode material and a negative electrode material on the inner wall 111 of the inner pot body 110 by means of cold spraying, and an overlapping area of the positive electrode material and the negative electrode material forms an electrode pair of the thin-film thermocouple.

Optionally, when the thin-film thermocouple is disposed on the inner pot body 110, an insulating material may be sprayed on the surface of the inner wall 111 to form an insulating layer, so that the thin-film thermocouple is insulated from the inner pot body 110, and then a positive electrode material and a negative electrode material are sequentially sprayed on the insulating layer to form the thin-film thermocouple. Since the thin film thermocouple is formed by spraying, and the thickness thereof is in the order of micrometers, it is formed directly on the inner wall 111 with little influence on the surface flatness of the inner wall 111.

As an alternative embodiment, the inner wall 111 of the inner pot body 110 is provided with a receiving portion, and the temperature sensor 120 is located in the receiving portion. In this embodiment, the accommodating portion is used for accommodating the temperature sensor 120, and especially when the selected temperature sensor 120 has a certain volume, the inner wall 111 after the temperature sensor 120 is disposed can be kept flat, which is convenient for cleaning the inner pot body 110. Alternatively, the receiving portion may be a groove, and the temperature sensor 120 is received in the groove.

Optionally, when the temperature sensor 120 is a thin-film thermocouple, before spraying the positive electrode material and the negative electrode material, a groove for arranging the thin-film thermocouple is formed in the inner wall 111 of the inner pot body 110 as a receiving portion, and is insulated from the inner pot body 110 by an insulating layer, and then the positive electrode material and the negative electrode material are sprayed in an overlapping manner in the groove to form an electrode pair of the thin-film thermocouple, wherein the depth of the groove is matched with the thickness of the thin-film thermocouple. The inner wall 111 of the inner pot body 110 is provided with the groove serving as the accommodating part, so that the thin film thermocouple formed after spraying is flush with the inner wall 111 of the inner pot body 110, the thermocouple and the inner pot body 110 are integrated, the inner pot body 110 is convenient to clean and use, a user feels no to the thin film thermocouple, and user experience is improved.

Further optionally, when the temperature sensor 120 is a thin film thermocouple, before spraying the positive electrode material and the negative electrode material, a groove for installing the thin film thermocouple is opened on the inner wall 111 of the inner pot body 110 as a receiving portion, the heat insulation layer is used for enabling the inner pot body 110 to be insulated from the inner pot body 110, the insulation layer is used for enabling the inner pot body 110 to be insulated from the inner pot body 110, and then the positive electrode material and the negative electrode material are sprayed in the groove in an overlapping manner to form an electrode pair of the thin film thermocouple. Through the arrangement of the heat insulation layer and the insulating layer, the thin film thermocouple is insulated and insulated from the inner pot body 110, and the interference of the temperature of the inner pot body 110 or the heat source to the temperature measurement of the thin film thermocouple can be avoided.

Optionally, when the temperature sensor 120 is a thermistor-type temperature sensor 120, compared to the thin-film thermocouple-type temperature sensor 120, the volume of the thermistor-type temperature sensor 120 is larger, a groove is formed in the inner wall 111 of the inner pot body 110 as a receiving portion, and a thermistor is disposed in the groove after an insulating layer and a heat insulation layer are disposed in the groove. Through the groove, the thermistor temperature sensor 120 can be better integrated with the inner wall 111 of the inner pot body 110, so that the surface of the inner wall 111 is smooth and convenient to clean.

As an alternative embodiment, as shown in fig. 11 to 13, the inner pot body 110 is opened with a through hole, and the conductor 130 passes through the through hole to be connected with the temperature sensor 120. The through hole is opened in the adjacent border department of interior pot body 110, and this through hole runs through inner wall 111 and the outer wall of interior pot body 110, makes the conductor can wear out to the outer wall from the inner wall of interior pot body 110, passes the through hole through conductor 130, is connected temperature sensor 120 with the outside realization of interior pot body 110 to the temperature signal of temperature sensor 120 that will be located interior pot body 110 inner wall 111 outwards transmits. Further, as shown in fig. 15 and 16, when the inner pot body is provided with the positioning assembly 150, the positioning assembly 150 may be fixed on the inner pot body 110 through the through hole.

As another alternative, as shown in fig. 1, 8 to 10, the conductor 130 extends from the inner wall 111 to the rim 112 or the outside of the inner pot body 110. The temperature sensor 120 is connected to the outer side of the inner pot body 110 by the conductor 130 extending from the inner wall 111 to the edge 112 or the outer side of the inner pot body 110, so that the temperature signal of the temperature sensor 120 located on the inner wall 111 of the inner pot body 110 is transmitted to the outside.

Further, a conductor 130 groove is formed on the inner wall 111 for accommodating the conductor 130, and preferably, an insulating layer may be disposed in the conductor 130 groove to insulate the conductor 130 from the inner pot body 110 to avoid electrical conduction. In this embodiment, the depth, opening size, etc. of the groove of the conductor 130 can be adaptively adjusted according to the setting parameters of the thickness, length, etc. of the conductor 130. As shown in fig. 1, since the thin film thermocouple is located on the inner wall 111 of the inner pot body 110, the inner conductive connection end 140 is located at the rim 112 or the outer side of the inner pot body 110, and is connected thereto by the conductor 130. As an alternative embodiment, conductor 130130 is a wire or thin film conductive layer, both ends of which are connected to the thermocouple and inner conductive connecting end 140140, respectively, thereby enabling connection between the thermocouple and inner conductive connecting end 140140. When the inner pot body 110 is provided with a through hole and the conductor 130 passes through the through hole to be connected with the temperature sensor 120, the conductor 130 is preferably a wire, that is, the temperature sensor 120 transmits a temperature signal outwards through the wire; when the conductor 130 extends from the inner wall 111 to the edge 112 or the outer side of the inner pot body 110, the conductor 130 is preferably a thin film conductive layer, which has a small thickness and has a small influence on the inner wall 111 when disposed on the inner wall 111.

Preferably, the conductor 130 is a thin film conductive layer, and accordingly, when the thin film conductive layer is prepared by a spraying method, a groove for the conductor 130 is formed in the inner wall 111 of the inner pot body 110 where the thin film conductive layer is located, and the thin film conductive layer is sprayed in the corresponding groove and is integrated with the inner pot body 110, so that the inner pot body 110 is convenient to clean and use.

In this embodiment, as an alternative, as shown in fig. 1, the thin film conductive layer includes a positive thin film conductive layer 131 that is the same as the positive electrode material of the thin film thermocouple and a negative thin film conductive layer 132 that is the same as the negative electrode material of the thin film thermocouple. That is, in the present application, a positive conductor 130 groove for accommodating the positive electrode thin film conductive layer 131 and a negative conductor 130 groove for accommodating the negative electrode thin film conductive layer 132 are formed in the inner side of the inner pot body 110, the positive electrode material same as the positive electrode of the thin film thermocouple is sprayed in the positive conductor 130 groove to form the positive electrode thin film conductive layer 131, and the positive electrode thin film conductive layer 131 is connected with the positive electrode of the thin film thermocouple; the negative electrode material same as the negative electrode of the thin film thermocouple is sprayed in the groove of the negative conductor 130 to form a negative electrode thin film conductive layer 132, the negative electrode thin film conductive layer 132 is connected with the negative electrode of the thin film thermocouple, and the positive electrode thin film conductive layer 131 and the negative electrode thin film conductive layer 132 are respectively accommodated in different grooves of the conductor 130, so that the positive electrode thin film conductive layer 131 and the negative electrode thin film conductive layer 131 are insulated from each other, thereby forming a conductive circuit among the thin film thermocouple, the thin film conductive layer and the inner conductive connecting end 140, and when the low-temperature electrode of the thin film thermocouple generates electromotive force, current passes through the conductive circuit.

As an alternative embodiment, only one conductor 130 groove is opened on the inner wall 111 of the inner pan body 110, the positive thin film conductive layer 131 and the negative thin film conductive layer 132 of the thin film conductive layer are both disposed in the conductor 130 groove, and an insulating layer is disposed between the positive thin film conductive layer 131 and the negative thin film conductive layer 132, so as to insulate the positive thin film conductive layer 131 and the negative thin film conductive layer 132. In other embodiments, only one conductor 130 groove is formed on the inner wall 111 of the inner pot body 110, the positive thin film conductive layer 131 or the negative thin film conductive layer 132 of the thin film conductive layers is disposed in the conductor 130 groove, the other thin film conductive layer is formed on the surface of the inner wall 111, and the positive thin film conductive layer 131 and the negative thin film conductive layer 132 are disposed at positions that do not overlap, so that the positive thin film conductive layer 131 and the negative thin film conductive layer 132 are insulated from each other.

As an alternative embodiment, the inner wall 111 of the inner pan body 110 may not be provided with the groove of the conductor 130, and the positive thin film conductive layer 131 and the negative thin film conductive layer 132 of the thin film conductive layer are directly and respectively disposed on the surface of the inner wall 111, and since the thickness of the thin film conductive layer is in the micron order by spraying, the influence of the direct formation of the thin film conductive layer on the inner wall 111 on the surface flatness of the inner wall 111 is small.

When the positive electrode thin film conductive layer 131 is prepared, the positive electrode thin film conductive layer and the thin film thermocouple can be prepared simultaneously, namely when the positive electrode of the thermocouple is formed by spraying a positive electrode material, the positive electrode material is sprayed to extend outwards from the positive electrode of the thermocouple to serve as the positive electrode thin film conductive layer 131; similarly, the negative electrode thin film conductive layer 132 may be formed simultaneously with the thin film thermocouple, that is, when the negative electrode of the thermocouple is formed by spraying the negative electrode material, the sprayed negative electrode material is extended from the negative electrode of the thermocouple to form the negative electrode thin film conductive layer 132.

Optionally, a protective layer is disposed on the surface of the thin film conductive layer, and the protective layer covers the thin film conductive layer to prevent friction and the like from affecting the thin film conductive layer.

As an alternative, the inner conductive connection 140 is a pogo pin or a contact, and accordingly, in the household appliance proposed in this application, the outer conductive connection 230 is a contact or a probe matching the inner conductive connection 140. When the pogo pin is brought into contact with the contact, an electrical connection is formed. In this embodiment, the inner conductive connection 140 is shown as a pogo pin, as shown in fig. 7 and 18. The probe is made of a conductive material and can be made to be retractable with respect to the positioning member 150, for example, by an elastic member such as a spring.
