Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating containers, in particular to a heating and heat-insulating container. Background Art

[0002] With technological advancements and improvements in people's living standards, heating and insulation containers have evolved from simple thermoses to products with multiple functions, including intelligent temperature control, efficient heat preservation, and convenient portability. Infants and young children, who take long mealtimes, require heat-insulating containers such as insulated bowls or cups for eating and drinking. Consequently, heating and insulation containers are becoming increasingly popular. However, existing heating and insulation containers suffer from poor heating efficiency and insulation due to the irrational layout of the heating device.

[0003] For example, the patent document with patent application number CN202020724828.2 and announcement date 2021.02.19 discloses a smart healthy constant temperature bowl, including a main body and a bowl lid. The main body is provided with an outer shell, an inner liner, a circuit control system, and an information sensing and detection system; the circuit control system and the information sensing and detection system are built into the enclosed space formed by the inner liner and the outer shell; the inner wall of the bowl lid is provided with a power supply, an ultraviolet lamp and a contact switch; the circuit control system includes a CPU, a wireless charging module, a heating module, a detection module and an Internet of Things monitoring module. The circuit control system, heating module, detection module and Internet of Things monitoring module are all electrically connected to the circuit board and the power supply. The CPU controls its operation, and can provide correction reminders and data record storage for the composition, strains, microorganisms of the food in the bowl and the eating habits of infants and young children, providing a scientific reference basis for their dietary health and eating habits.

[0004] In the smart healthy constant temperature bowl described in the above literature, the heating plate is built into the enclosed space formed by the inner tank and the outer shell, and heating is achieved by fitting the heating plate and the inner tank, while the temperature sensor is arranged at the bottom of the heating plate for temperature detection. Since the heating plate is arranged at the bottom of the inner tank and the temperature sensor is arranged at the bottom of the heating plate, and the temperature sensor needs to be arranged at the bottom of the heating plate through other mounting structures, the mounting structure is complicated. In addition, since the temperature sensor is arranged at the bottom of the heating plate and other components are arranged on the outside of the temperature sensor, the temperature measured by the temperature sensor is easily affected by other components, resulting in inaccurate temperature measurement by the temperature sensor. At the same time, the heating plate needs to be connected to the power supply, and its layout affects the uniformity of power supply heating. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a heating and heat-insulating container with a simple structure, uniform heating and good temperature measurement reliability.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a heating and heat-insulating container, comprising a main body, the main body comprising an outer shell and an inner shell, the inner shell being provided with a heating device, the heating device comprising a bottom heating plate, the bottom heating plate comprising a first heating area and a second heating area, an electrical connection area being provided on one side of the bottom of the inner shell, the first heating area and the second heating area forming a heating area with a notch on one side and a blank area in the center, the heating areas being arranged in a ring-shaped distribution with the center of the bottom circle of the inner shell as the center, a temperature sensor being provided on the center of the bottom of the inner shell, and the electrical connection line of the temperature sensor extending through the notch to the electrical connection area on one side of the bottom of the inner shell.

[0007] The above arrangement forms a heating area of ​​the bottom heating plate through the first heating area and the second heating area. The heating area is an annular area with a notch on one side, which can effectively and evenly heat the inner shell. At the same time, it can also enable a temperature sensor to be set in the central blank area of ​​the inner shell, which can also facilitate the layout of the temperature sensor. Setting the temperature sensor in the center of the inner shell can enable the temperature sensor to be directly close to the inner shell, so that the temperature of the inner shell can be accurately measured, resulting in a simple structure and high temperature measurement reliability.

[0008] Furthermore, the heating device further comprises two or more side heating plates, which are evenly spaced along the circumferential direction of the bottom of the outer wall of the inner shell, and each side heating plate has a rectangular cutout.

[0009] The above arrangement, by arranging the side heating plate on the outer wall, can heat from the outer wall of the inner shell, and heat the entire inner shell together with the bottom heating plate, thereby improving the heating effect.

[0010] Furthermore, the first heating area includes a first heating line, which first extends toward the center of the inner shell and then meanders around one side of the bottom of the inner shell before crossing from one side of the bottom of the inner shell to the other side and meanders around the other side of the bottom of the inner shell before being led out from one side of the bottom of the inner shell. The second heating area includes a second heating line, which first extends toward the center of the inner shell and then meanders around the other side of the bottom of the inner shell before crossing from the other side of the bottom of the inner shell to one side and meanders around one side of the bottom of the inner shell before being led out from the other side of the bottom of the inner shell.

[0011] According to the above arrangement, a first heating area is provided with a circuitous first heating line and a second heating line, and the second heating area is also provided with a circuitous first heating line and a second heating line, and the first heating line and the second heating line also cross the first heating area to the second heating area, so that the entire heating area can be more uniform and reliable, and if one heating line is damaged, it will not cause the entire heating plate to fail to heat.

[0012] Furthermore, the first heating wire on the first heating area is wrapped around the outside of the second heating wire, and the second heating wire on the second heating area is wrapped around the outside of the first heating wire.

[0013] The above arrangement facilitates the layout of the heating wires while also ensuring heating reliability by enclosing the first heating area and the second heating area with the first heating wire and the second heating wire.

[0014] Furthermore, the first heating line spans from one side to the other side at the innermost and outermost sides of the annular bottom of the inner shell, and the second heating line spans from the other side to one side at the outermost side of the annular bottom of the inner shell.

[0015] The above arrangement can facilitate the first heating wire and the second heating wire to be conveniently arranged across and covering the first heating area to the second heating area.

[0016] Furthermore, a groove is provided on the top of the inner shell along the circumferential direction, and a protrusion is provided on the top of the outer shell along the circumferential direction, and the protrusion fits in the groove.

[0017] The above setting increases the sealing between the inner shell and the outer shell through the combination of the protrusion and the groove, effectively isolates the external air, and helps to maintain the internal temperature. The combination of the protrusion and the groove can also effectively prevent moisture or dust from entering through the gap, protecting the internal food from contamination. The fit between the protrusion and the groove can effectively prevent the outer shell from sliding or rotating relative to the inner shell, thereby improving the stability of the product during use.

[0018] Furthermore, there is a gap between the inside of the outer shell and the bottom of the inner shell.

[0019] The above arrangement, by providing a gap between the inside of the outer shell and the bottom of the inner shell, can effectively reduce heat transfer through direct contact, thereby keeping the outer shell surface and the inner shell cool to the touch and preventing users from getting burned when taking hot food.

[0020] Furthermore, a bowl cover is provided above the main body, and a handle is provided at the center of the top of the bowl cover.

[0021] The above settings, through the handle setting, make it easier for us to open and close, avoiding burns or slipping. It increases the beauty of the bowl cover and makes it look more refined and practical.

[0022] Furthermore, handshakes are provided on both sides of the shell.

[0023] The above settings often need to be moved from the storage position to the use position when in use. The handshakes on both sides can make it easier to grasp and carry, especially when there is a lot of food in the inner shell, which is more convenient to operate. Whether it is a left-handed or right-handed user, the handshake design on both sides can ensure that everyone can use it conveniently, thereby improving the applicability of the product.

[0024] Furthermore, an anti-slip ring is provided at the bottom of the shell.

[0025] The above setup, when used on a kitchen countertop, may sometimes move due to kitchen activities. The anti-slip ring at the bottom of the housing can effectively prevent this from sliding, ensuring stability during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0036] Example 1.

[0037] like Figures 1 to 6As shown, a heating and heat-insulating container includes a main body, the main body includes an outer shell 6 and an inner shell 7, the inner shell 7 is provided with a heating device, the heating device includes a side heating plate 1 and a bottom heating plate 2, the bottom heating plate 2 includes a first heating area 21 and a second heating area 22, and an electrical connection area is provided on one side of the bottom of the inner shell. The first heating area 21 and the second heating area 22 form a heating area with a notch on one side and a blank area in the center. The heating areas are arranged in a ring shape with the center of the bottom circle of the inner shell as the center. A temperature sensor 8 is provided on the center of the bottom of the inner shell, and the electrical connection line of the temperature sensor 8 extends through the notch to the electrical connection area 15 on one side of the bottom of the inner shell.

[0038] like Figure 6 As shown, the first heating area 21 includes a first heating line 221, which first extends toward the center of the inner shell and then meanders around one side of the bottom of the inner shell before crossing from one side of the bottom of the inner shell to the other side and meanders around the other side of the bottom of the inner shell before being led out from one side of the bottom of the inner shell. The second heating area 22 includes a second heating line 221, which first extends toward the center of the inner shell and then meanders around the other side of the bottom of the inner shell before crossing from the other side of the bottom of the inner shell to one side and meanders around one side of the bottom of the inner shell before being led out from the other side of the bottom of the inner shell.

[0039] The first heating wire 211 on the first heating region 21 is wrapped around the outside of the second heating wire 221 , and the second heating wire 221 on the second heating region 22 is wrapped around the outside of the first heating wire 211 .

[0040] The first heating line 211 spans from one side to the other at the innermost and outermost sides of the bottom ring of the inner shell, and the second heating line 221 spans from the other side to one side at the outermost side of the bottom ring of the inner shell.

[0041] A first heating line 211 and a second heating line 221 are arranged in a circuitous manner in the first heating area 21, and a first heating line 211 and a second heating line 221 are arranged in a circuitous manner in the second heating area 22. The first heating line 211 and the second heating line 221 also cross the first heating area 21 to the second heating area 22, so that the entire heating area can be more uniform and reliable, and if one heating line is damaged, it will not cause the entire heating plate to fail to heat.

[0042] like Figure 1 As shown, the side heating plates 1 are evenly arranged in a ring layout along the circumferential direction of the bottom end of the outer wall of the inner shell 7, and there are cutouts 11 between the side heating plates 1. The heating wires on the side heating plates 1 are arranged in a circuitous manner along the ring direction at the bottom end of the outer wall of the inner shell 7.

[0043] Through the cooperation of the bottom heating plate 2 and the side heating plate 1, heat can be transferred from the bottom and side wall of the container at the same time, which helps to make the overall temperature of the inner shell 7 more uniform. The incision design between the side heating plates 1 is to set a heat conduction path so that the heat is evenly distributed on the bowl wall. The bottom heating plate 2 and the side heating plate 2 heat the inner shell 7, which increases the temperature of the inner shell 7. Due to the reasonable layout of the heating plates, the coverage area of ​​the heating plates can be maximized in a limited space, so that the heating plates heat the inner shell 7 evenly, making the heat transfer more uniform, reducing energy loss, and improving the conversion efficiency of electrical energy to thermal energy, thereby improving energy efficiency and avoiding local overheating and local non-heating.

[0044] In this embodiment, Figure 2 and Figure 3 As shown, a groove 14 is provided on the top of the inner shell 7 along the circumferential direction, and a protrusion 13 is provided on the top of the outer shell along the circumferential direction. The protrusion 13 fits with the groove 14. The combination of the protrusion 13 and the groove 14 increases the sealing between the inner shell 7 and the outer shell 6, effectively isolates the external air, and helps to maintain the internal temperature. The combination of the protrusion 13 and the groove 14 can also effectively prevent moisture or dust from entering through the gap, protecting the internal components from contamination. The fit between the protrusion 13 and the groove 14 can effectively prevent the outer shell 6 from sliding or rotating relative to the inner shell 7, and prevent the inner shell 7 and the outer shell 6 from falling off during use, causing accidents, thereby improving the stability of the product during use.

[0045] There is a gap between the inside of the outer shell 6 and the bottom of the inner shell 7. By setting the gap between the inside of the outer shell 6 and the bottom of the inner shell 7, the heat transfer through direct contact can be effectively reduced, the unnecessary contact heat loss can be reduced, and the temperature of the inner shell can be better maintained. Because there is a gap between the inside of the outer shell 6 and the bottom of the inner shell 7, the heat is not transferred to the outer shell 6 through contact, and the outer shell 6 will not become hot due to the heating of the inner shell 7, thereby maintaining the cool touch of the surface of the outer shell 6 and the inner shell 7, preventing users from getting burned when taking hot food.

[0046] like Figure 1 As shown, a bowl cover 3 is provided above the main body, and a handle 4 is provided in the center of the top of the bowl cover 3. In this embodiment, the handle 4 is set in the shape of an astronaut. Through the setting of the handle 4, it can be opened and closed more conveniently, avoiding scalding or slipping. The handle 4 is set in the shape of an astronaut, which increases the aesthetics of the bowl cover 3 and makes it look more refined and practical.

[0047] Handles 5 are provided on both sides of the outer shell 6. When in use, it is often necessary to move it from the storage position to the use position. The handshakes 5 on both sides can make it easier to grasp and carry, especially when there is a lot of food in the inner shell 7. It is more convenient to operate. Whether it is a left-handed or right-handed user, the handshake 5 design on both sides can ensure that everyone can use it conveniently, thereby improving the applicability of the product.

[0048] The bottom of the housing 6 is provided with an anti-slip ring 12. When used on a workbench, which may sometimes move due to the movement of the workbench, the anti-slip ring 12 effectively prevents relative sliding of the housing 6 with the workbench. The anti-slip ring 12 ensures that the bottom of the housing 6 remains stable during use. The anti-slip ring 12 isolates the heat from the bottom of the housing 6 from the workbench, reducing the amount of heat transferred from the housing 6 to the workbench, maintaining the original temperature of the workbench, and preventing burns when removing the container to use the workbench.

[0049] The working principle of the present invention is as follows: the heating area of ​​the bottom heating plate 2 is formed by the first heating area 21 and the second heating area 22. The heating area is an annular area with a notch on one side, which can effectively and evenly heat the inner shell. At the same time, the temperature sensor 8 can be set in the central blank area of ​​the inner shell, which can also facilitate the layout of the temperature sensor 8. Setting the temperature sensor 8 in the center of the inner shell can make the temperature sensor 8 directly close to the inner shell, so that the temperature of the inner shell can be accurately measured. The structure is simple and the temperature measurement reliability is high.
