Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The embodiment of the present invention provides a heating device 10 for heating a container, which can be a cavity for containing liquid, for example, a heatable kettle. The container may also be a cooking pot with a cooking cavity. Of course, in other embodiments of the present invention, the heating device 10 can also be used to heat other devices, and is not limited herein.
Referring to fig. 1 to 4, a heating device 10 according to the present invention will be described. A heating appliance 10 includes a housing 100, an infrared heating element 200 and a thermostat 300. Specifically, the housing 100 has a housing space 101. The housing 100 includes a shell 110 and a top 120. The top 120 covers the housing 110 to form a receiving space 101. In this embodiment, the top 120 and the housing 110 are separated, and the top 120 and the housing 110 are detachably connected. It is understood that in other embodiments, the top 120 is integrally connected to the housing 110.
Further, in the present embodiment, the top portion 120 has a transmissive region. The transmissive region covers the entire top 120. It is understood that in other embodiments, the transmissive region only covers a portion of the top 120. Further, in the present embodiment, the top 120 is a glass-ceramic panel 120. Infrared light can be transmitted through the crystallized glass panel 120 to heat the container. The crystallized glass panel 120 serves to support the container and can insulate the container from heat.
Further, the infrared heating element 200 is accommodated in the accommodating space 101 and attached to the top 120. The infrared heating element 200 can emit infrared rays penetrating the transmission region, and the infrared rays are used to heat the container placed on the top 120. In this embodiment, the infrared heating member 200 is an infrared heating film 200. The infrared heating element 200 is attached to one side of the top 120 close to the receiving space 101 by coating. The infrared rays emitted by the infrared heating element 200 replace a high-frequency magnetic field to heat the container, so that the generation of electromagnetic noise and noise emitted by a cooling fan is avoided, and the use comfort of a user is improved. The infrared heating element 200 is annularly arranged on the temperature controller 300 and has a gap with the temperature controller 300, that is, a clearance area is arranged on the part of the infrared heating element 200 corresponding to the temperature controller 300, so that the temperature controller 300 can accurately measure the temperature of the container, and the interference of the infrared heating element 200 to the temperature controller is avoided.
Further, the thermostat 300 is disposed at the housing 100. The thermostat 300 is used to monitor the temperature of the container and adjust the emission power of the infrared heating element 200 according to the monitoring result. And the temperature change state of the container is monitored in real time, so that accurate temperature control is performed in real time.
Further, the thermostat 300 includes a sensor assembly 310 and a main control circuit board 320, the sensor assembly 310 is used for monitoring the temperature of the container and transmitting the monitoring result to the main control circuit board 320, and the main control circuit board 320 is used for adjusting the emission power of the infrared heating element 200 according to the monitoring result. Further, the sensor assembly 310 includes a probe 311, a holder, and a thermistor 312 provided on the probe 311, the probe 311 is connected with the case 100 through the holder, and the probe 311 can abut on the container and transfer heat of the container to the thermistor 312. The probe 311 is exposed at the top 120 and can be abutted against the bottom of the container. As the infrared heating of the container proceeds, the temperature of the container increases, and the heat it generates can be transferred to the thermistor 312 through the probe 311. The thermistor 312 can exhibit different resistance values at different temperatures to produce changes in the electrical signal, e.g., current and/or voltage, which the main control circuit board 320 can adjust the power emitted by the infrared heating element 200. Specifically, the main control circuit board 320 is electrically connected to the thermistor 312 and the infrared heating element 200, for example, when the temperature of the container is too high as a result of the monitoring, a corresponding electrical signal is transmitted to the main control circuit board 320, and the main control circuit board 320 adjusts the emission power of the infrared heating element 200 to be reduced, thereby preventing the container from overheating.
Further, the transmission region has a through hole 121, and the temperature controller 300 is disposed through the through hole 121. The temperature controller 300 is connected with the transmission region in a split manner, so that the maintenance and replacement are convenient. Specifically, the bracket is accommodated in the accommodating space 101, the bracket includes an outer bracket body 313 and an inner bracket body 314, the probe 311 is disposed at one end of the inner bracket body 314, the outer bracket body 313 is fixedly connected with the housing 100, the sensor assembly 310 further includes an elastic member 315 located between the outer bracket body 313 and the inner bracket body 314, and the elastic member 315 is used for driving the inner bracket body 314 to move relative to the outer bracket body 313 so as to extend the probe 311 from the through hole 121 and abut against the container. Under the elastic force of the elastic member 315, the inner frame 314 drives the probe 311 and the thermistor 312 to move together, so that the probe 311 is located above the transmission region, and when the container is placed in the transmission region, the container presses down the probe 311 and compresses the elastic member 315, so that the probe 311 and the container are attached more tightly, and the temperature of the container is accurately monitored.
Further, the receiving space 101 further receives a support member 102, one end of the support member 102 is fixedly connected to the housing 100, and the other end of the support member 102 abuts the outer frame body 313 to the top 120. Specifically, the support member 102 is cylindrical and provided with a receiving cavity. The outer frame body 313 includes an insertion portion and an abutting portion connected in sequence, the insertion portion is inserted into the accommodating cavity and inserted into the supporting member 102, and the abutting portion abuts against the top portion 120 through the supporting member 102. The inner frame 314 includes a head end and a tail end, and the probe 311 is enclosed in the head end to wrap the head end. The head end has a hole, which penetrates the inner frame 314 from the head end to the tail end, and the thermistor 312 is inserted into the hole and connected with the probe 311. Further, the tail end is inserted in the insertion part. In this embodiment, the elastic member 315 is a spring 315. The spring 315 is sleeved outside the tail end. The two ends of the spring 315 are respectively abutted against the head end and the insertion part.
Further, a sealing member 400 is disposed between the outer frame 313 and the top 120, and the sealing member 400 is used for sealing the through hole 121 and the receiving space 101. The sealing member 400 can prevent liquid in the container, for example, soup overflowing during cooking or liquid flowing into the accommodating space 101 from flowing into the gap between the through hole 121 and the temperature controller 300 when the heating device 10 is wiped, so that the electrical components in the accommodating space 101 are damaged or the liquid flowing into the accommodating space 101 cannot be cleaned and bacteria are grown. Fig. 2 is a cross-sectional view of the probe 311 in the through-hole 121, without the seal 400.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
