Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating furnaces, and in particular to a microcrystalline furnace with an anti-scalding reminder function. Background Technology
[0002] Microcrystalline furnaces are widely used electric heating furnaces, known for their high thermal efficiency and energy conservation. Their microcrystalline glass panels are typically more robust and durable, with good heat dissipation and heat transfer properties. The main structure consists of an internal furnace plate and coil, temperature detection components, and internal heat dissipation components. Common temperature detection components used in microcrystalline furnaces include infrared temperature sensors and contact temperature sensors. Infrared temperature sensors typically only detect temperature while an object is being heated, stopping detection or exhibiting significant errors when the object is removed from the microcrystalline glass. Contact temperature sensors, located inside the microcrystalline furnace and pressed against the panel, suffer from temperature detection discrepancies due to variations in adhesion. Furthermore, the internal heat dissipation components cause a temperature difference between the contact temperature sensor's environment and the microcrystalline glass panel, resulting in larger errors. Cleaning the microcrystalline glass after heating and removing the object can cause burns. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0021] The following is combined with Figures 1 to 4 The microcrystalline oven with anti-scalding reminder function provided in this embodiment will be further described as follows:
[0022] Please refer to Figure 1 This utility model provides a microcrystalline oven with anti-scalding reminder function, including a microcrystalline glass plate 1, a bottom cavity shell 2, and an oven tray 3; at least one oven tray 3 is provided, and the oven tray 3 is installed in the cavity of the bottom cavity shell 2 by a plurality of oven tray elastic supports 7. The microcrystalline glass plate 1 is installed on the top of the bottom cavity shell 2, and the oven tray elastic supports 7 provide elastic support for the oven tray 3, so that the top edge of the oven tray 3 presses against the microcrystalline glass plate 1, ensuring the sealing of the oven tray cavity.
[0023] The furnace tray 3 is provided with a furnace tray cavity groove. A thermocouple 4 is embedded in the center of the furnace tray cavity groove. A thermocouple end heat conductor 8 is installed on the top of the thermocouple 4. The thermocouple end heat conductor 8 is used to accurately and quickly transfer the heat of the microcrystalline glass plate 1 to the thermocouple 4, so as to realize the real-time temperature display of the microcrystalline glass plate 1 and realize the anti-scalding reminder function. The furnace tray cavity groove is also provided with a furnace tray coil (not shown in the figure). As a common structure of existing microcrystalline furnaces, its structural features and installation method will not be further described.
[0024] The bottom of the microcrystalline glass plate 1 is provided with a microcrystalline glass limiting ring 9, and the top of the thermocouple end heat conductor 8 is set in the annular groove of the microcrystalline glass limiting ring 9. The annular groove has a good heat conduction effect and can effectively isolate the influence of the temperature inside the furnace plate cavity, thereby making the temperature detection of the thermocouple 4 more accurate.
[0025] The microcrystalline oven with anti-scalding reminder function also includes a main control board 5 and a touch display circuit board 6. Both the main control board 5 and the touch display circuit board 6 are installed inside the cavity of the bottom shell 2 and are fixed by screws. The main control board 5 is located at the bottom of the oven plate 3. The main control board 5 is model AWP01-2D11 and the main control chip is SC92F84A3. The touch display circuit board 6 is model AWRT10-2D11.
[0026] like Figures 1-4 As shown, embodiments of this utility model also disclose the following more optimized specific structures:
[0027] The furnace tray elastic support 7 consists of spring-loaded lugs 71 and limiting spring-loaded rods 72, as detailed below. Figure 3The spring pin ear 71 is fixed to the bottom side of the furnace plate 3. The spring pin ear 71 is provided with a column insertion hole. The limiting spring pin 72 is inserted into the column insertion hole. The furnace plate spring 73 is sleeved on the limiting spring pin 72 at the bottom of the column insertion hole. The furnace plate spring 73 is a conical spring with a large bottom area to increase its stability. The bottom end of the limiting spring pin 72 is fitted with a column bottom screw sleeve 74 through a thread. The column bottom screw sleeve 74 is fixed to the bottom cavity shell 2. It is detachable through the thread, which facilitates the replacement and maintenance of the furnace plate elastic support 7.
[0028] The thermocouple end heat conductor 8 consists of a heat-conducting pressure plate 81 and a heat-conducting sleeve 82 installed at the center of the bottom of the heat-conducting pressure plate 81, as detailed in the following document. Figure 4 The thermally conductive sleeve 82 is fitted onto the top of the thermocouple 4, and the space between the thermally conductive sleeve 82 and the thermocouple 4 is filled with silicone grease to improve its thermal conductivity.
[0029] The bottom of the heat-conducting pressure plate 81 is equipped with several short bottom posts 84, and a bottom spring 83 is sleeved on the bottom posts 84. The natural length of the bottom spring 83 is more than twice the length of the bottom posts 84, which allows the heat-conducting pressure plate 81 to be tightly pressed onto the microcrystalline glass plate 1, so as to achieve good temperature transfer.
[0030] The touch display circuit board 6 is equipped with touch buttons and a display device, which can be a common digital tube, and will not be described in detail here.
[0031] The bottom shell 2 is provided with heat dissipation holes 10, and the bottom of the furnace plate 3 is provided with a heat dissipation fan (not shown in the figure). This is a common heat dissipation method for microcrystalline furnaces, which will not be described in detail here.
[0032] An adhesive strip 11 is fixedly installed on the top edge of the bottom cavity shell 2. The microcrystalline glass plate 1 is glued to the adhesive strip 11, and heat-resistant adhesive is used for this bonding.
[0033] like Figures 1-4 The microcrystalline oven with anti-scalding reminder function shown primarily achieves this function through precise temperature display of the microcrystalline glass plate 1. The microcrystalline glass plate 1 itself has good thermal conductivity, and its surface temperature is relatively uniform, with little difference between the center temperature and the surrounding temperature. Since the bottom of the heated object placed on the microcrystalline oven with anti-scalding reminder function will transfer some heat to the microcrystalline glass plate 1, the center temperature of the microcrystalline glass plate 1 will be higher after use. At this time, the thermocouple end heat conductor 8 displays the temperature of the microcrystalline glass plate 1 in real time. Even if the heated object is removed, a reminder can be displayed to avoid burns during wiping.
[0034] In the above structure, the thermocouple end heat conductor 8 conducts heat transfer and is tightly pressed against the microcrystalline glass plate 1 by an elastic component. Compared with traditional probe sensing, the heat transfer is more accurate. Furthermore, the thermocouple end heat conductor 8 is set inside the microcrystalline glass limiting ring 9, which is less affected by the temperature inside the furnace plate cavity, further improving its accuracy and accurately realizing the anti-scalding reminder function.
[0035] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
