Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating kitchenware, in particular to a heat-insulating bowl. Background Art

[0002] Insulated bowls are one of the common tableware in people's daily life, and they are very popular because they can keep food warm. Specifically, the insulated bowls on the market usually include a bowl body and a heating cavity, wherein the bowl body is sleeved into the heating cavity and heated by the heating cavity, wherein a temperature sensor is arranged at the bottom of the heating cavity corresponding to the bowl body, so as to detect the heating temperature of the bowl body.

[0003] However, there is at least one of the following problems in the related technology: since the above technology obtains the heating temperature of the bowl body by abutting the corresponding bottom of the bowl body through the temperature sensor, combined with the characteristics of the detachable fit between the bowl body and the heating cavity, the temperature sensor is easily damaged during the process of repeatedly taking and placing the bowl body on the heating cavity. Utility Model Content

[0004] The technical problem solved by the utility model is that due to the matching method of the temperature sensor abutting the corresponding bottom of the bowl body in the related technology to obtain the heating temperature acting on the bowl body, combined with the characteristics of the detachable matching between the bowl body and the heating cavity, the temperature sensor is easily damaged during the process of repeatedly taking and placing the bowl body on the heating cavity.

[0005] In order to solve the above problems, the utility model provides an insulation bowl, comprising: a heating cavity, the heating cavity is provided with a receiving groove; a bowl body, the bowl body is installed in the receiving groove; a temperature measuring element, the temperature measuring element is arranged at a position of the bowl body corresponding to the receiving groove, and is used to detect the temperature of the bowl body; wherein, when the bowl body is installed in the receiving groove, a temperature measuring distance is formed between the temperature measuring element and the bowl body.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: In the related art, due to the point-contact temperature measurement method, the contact of the temperature measuring element is directly in contact with the bottom of the bowl body, so as to collect the temperature of the bowl body. However, in combination with the actual use of the thermal insulation bowl, in the process of taking and placing the bowl body many times, it is inevitable that the contact of the temperature measuring element is hit by the bowl body, which can easily damage the temperature measuring element. Therefore, through this technical solution, by adopting the distance temperature measurement method, a temperature measuring distance is formed between the temperature measuring element and the bowl body, which effectively avoids the above-mentioned risks; in addition, since the bowl body and the temperature measuring element are separated, it is ensured that in the process of taking and placing the bowl body many times, the bowl body is prevented from squeezing or impacting the temperature measuring element, causing the temperature measuring position of the temperature measuring element relative to the bowl body in the heating cavity to shift, thereby reducing the temperature measurement accuracy.

[0007] In one example of the utility model, the temperature measuring element is arranged in the installation space of the heating cavity; the heating cavity is provided with a light-transmitting component, and the light-transmitting component is installed to the position of the temperature measuring element in the receiving groove; wherein, when the bowl body is installed in the receiving groove, the light-transmitting component is located between the bowl body and the temperature measuring element.

[0008] Compared with the prior art, the technical effect achieved by adopting this technical scheme is as follows: specifically, on the one hand, by arranging a light-transmitting member on the heating cavity, it is ensured that the temperature measuring element can transmit the temperature measuring light to the bowl body through the light-transmitting member, thereby accurately obtaining the temperature of the bowl body. In contrast, if there is no light-transmitting member, in order to ensure the temperature measurement effect, the position of the heating cavity corresponding to the installation of the temperature measuring element is opened. Therefore, in the technical scheme of exposing the temperature measuring element to the receiving groove, the temperature measuring element cannot be well protected, and impurities are easily attached to the contacts of the temperature measuring element, thereby reducing the temperature measurement efficiency of the temperature measuring element. On the other hand, by arranging the light-transmitting member, the temperature measuring element is protected to a certain extent. Specifically, the temperature measuring element is isolated from the installation environment where the bowl body is installed, that is, it can be understood that the bowl body is arranged outside the heating cavity, and the temperature measuring element is isolated from the outside through the isolation effect of the light-transmitting member, thereby further reducing the influence of taking and placing the bowl body on the temperature measuring element.

[0009] In an example of the present invention, a stepped hole is provided at a position of the heating cavity corresponding to the accommodating groove; and the light-transmitting member is installed in the stepped hole.

[0010] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: specifically, the stepped hole is specifically composed of a large hole and a small hole arranged coaxially, the large hole is arranged on the side of the small hole away from the temperature measuring element, and by installing the light-transmitting part into the large hole, the cooperation of the two can achieve the effect of stably installing the light-transmitting part. For example, the light-transmitting part can be fixed to the heating cavity by applying glue or using ultrasound.

[0011] In one example of the present invention, the temperature measuring element includes an infrared temperature sensor; the coverage angle of the infrared temperature sensor acting on the light-transmitting member is defined as a, and the preset effective angle range of the infrared temperature sensor is defined as b; wherein ab≥k>0°, k is a preset parameter value.

[0012] Compared with the prior art, the technical effect achieved by adopting this technical solution is: ensuring the temperature measurement efficiency of the infrared temperature sensor.

[0013] In an example of the present invention, the heating cavity comprises: a control heating module, and the control heating module is arranged in the installation space of the heating cavity.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: specifically, through modular design, the difficulty of disassembling and controlling the heating module is reduced, thereby improving the disassembly and assembly efficiency.

[0015] In one example of the utility model, the control heating module includes: a power supply component, which is arranged in the installation space; a heating coil component, which is electrically connected to the power supply component and is arranged in the heating area of ​​the heating cavity corresponding to the receiving groove; and a magnetic isolation component, which is clamped between the heating coil component and the power supply component.

[0016] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: for example, the heating coil assembly provides high-frequency alternating current through the power supply assembly, thereby generating an alternating magnetic field. The alternating magnetic field generates eddy currents inside the bowl body, thereby generating heat itself. Since the magnetic field is three-dimensional in space, the alternating magnetic field will affect the battery and PCB circuit board in the power supply assembly, thereby causing the battery and PCB circuit board to generate heat, affecting battery life and increasing energy consumption. Therefore, by adding a magnetic isolation component between the heating coil assembly and the power supply assembly, the effect of the alternating magnetic field on the battery and PCB circuit board can be eliminated, thereby achieving the effect of improving energy efficiency.

[0017] In one example of the utility model, the heating coil assembly includes: a coil bracket, which is installed on the side of the power supply assembly close to the bowl body; a magnetic coil, which is arranged on the side of the coil bracket away from the power supply assembly; wherein the magnetic isolation member is clamped between the coil bracket and the magnetic coil.

[0018] Compared with the prior art, the technical effect achieved by adopting this technical solution is: the magnetic isolation effect of the magnetic isolation component is further improved.

[0019] In one example of the utility model, the power supply assembly includes a power storage bracket and a power storage group that cooperate with each other; the coil bracket is snap-connected with the power storage bracket to form an assembly space for installing the power storage group.

[0020] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the battery can be easily disassembled and assembled from the assembly space by clamping the coil bracket and the power storage bracket.

[0021] In an example of the present invention, a space for accommodating a temperature measuring element is provided in the middle of the control heating module.

[0022] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting a clearance space at the center position of the control heating module, on the one hand, the position setting between the internal components of the heating cavity is made more compact, thereby improving the utilization rate of the internal installation space; on the other hand, since the temperature measuring element is set in the clearance space, compared with other positions, it is ensured that the temperature measuring element is placed below the bowl body near its center. If it is placed on the outside of the bowl body or deviated from the center position of the control heating module, the volume and weight of the entire insulation bowl will be increased. If it is placed between the center and the outside, the magnetic coil needs to make way for the infrared temperature sensor. Since the magnetic coil is continuously wound, the magnetic coil will be irregular, which will increase the difficulty and cost of production.

[0023] In one embodiment of the present invention, the power storage group includes a plurality of batteries; the plurality of batteries are arranged in parallel with each other, or at least two of the plurality of batteries are arranged at an angle to each other.

[0024] After adopting the technical solution of the utility model, the following technical effects can be achieved:

[0025] (1) By adopting the method of temperature measurement with a distance, a temperature measuring distance is formed between the temperature measuring element and the bowl body, which effectively avoids the above-mentioned risks; in addition, since the bowl body and the temperature measuring element are separated, it is ensured that during the process of taking and placing the bowl body multiple times, the bowl body is prevented from squeezing or impacting the temperature measuring element, causing the temperature measuring position of the temperature measuring element relative to the bowl body in the heating cavity to shift, thereby reducing the temperature measurement accuracy;

[0026] (2) On the one hand, by arranging a light-transmitting member on the heating cavity, it is ensured that the temperature measuring element can transmit the temperature measuring light to the bowl body through the light-transmitting member, thereby accurately obtaining the temperature of the bowl body. In contrast, if there is no light-transmitting member, in order to ensure the temperature measurement effect, the position of the heating cavity corresponding to the installation of the temperature measuring element is made to be open. Therefore, in the technical scheme of exposing the naked temperature measuring element to the receiving groove, the temperature measuring element cannot be well protected, and impurities are easily attached to the contacts of the temperature measuring element, thereby reducing the temperature measurement efficiency of the temperature measuring element. On the other hand, by arranging the light-transmitting member, the temperature measuring element is protected to a certain extent. Specifically, the temperature measuring element is isolated from the installation environment of the bowl body. That is, it can be understood that the bowl body is arranged outside the heating cavity, and the temperature measuring element is isolated from the outside through the isolation effect of the light-transmitting member, so that the installation environment in which it is located is isolated from the outside, thereby further reducing the influence of taking and placing the bowl body on the temperature measuring element.
