Description
本發明是有關於一種電磁爐測溫技術領域，特別是指一種電磁爐溫度感測結構及其組裝方法。 The invention relates to the technical field of temperature measurement of an induction cooker, in particular to an induction cooker temperature sensing structure and an assembly method thereof.
目前，在某些商用加熱設備上，因販賣的商品必須符合食品衛生法規，且要儘量延長商品壽命，因此準確的控溫成為必要條件，而傳統電磁加熱設備的溫度感測器放在黑晶板底部，因晶板底部不平整與機內流動的氣流，使得準確性不足。 At present, in some commercial heating equipment, the products sold must comply with food hygiene regulations and the product life should be extended as much as possible. Therefore, accurate temperature control becomes a necessary condition. The temperature sensor of traditional electromagnetic heating equipment is placed on the black crystal. At the bottom of the board, the accuracy is insufficient due to the uneven bottom of the crystal board and the airflow flowing in the machine.
傳統電磁爐對於溫度的偵測是極為粗略的，以軟膠或軟質發泡材料頂著溫度感測器向上觸碰在黑晶板底部，不僅鍋具與黑晶板接觸狀況無法被控制，且不平整的黑晶板底部與溫度感測器的接觸也得不到良好的保障，更還有機殼內的風扇影響溫度感測器的感溫；因一般用途，並不需要精准的溫度控制，因此我們使用傳統電磁爐加熱食材時，火力永遠也調不到適當的位置。 The traditional induction cooker is very rough for temperature detection. It uses soft rubber or soft foaming material to touch the temperature sensor up to the bottom of the black crystal plate. Not only the contact status of the pot and the black crystal plate cannot be controlled, but also The contact between the bottom of the flat black crystal plate and the temperature sensor is not guaranteed, and the fan in the case affects the temperature of the temperature sensor; for general use, precise temperature control is not required. Therefore, when we use traditional induction cookers to heat food, the firepower will never be adjusted to the proper position.
針對這個問題，當然也有商用設備改善這現象，但還是有出現其他不良現象，例如溫度感測器放在角落，導致測溫不准，或是溫度感測器穿過黑晶板，雖然能得到準確的溫度訊息，但黑晶板中間穿孔導致強度不足，極易發生破損等問題。 To solve this problem, of course there are commercial equipment to improve this phenomenon, but there are still other undesirable phenomena. For example, the temperature sensor is placed in the corner, resulting in inaccurate temperature measurement, or the temperature sensor passes through the black crystal board, although it can be obtained Accurate temperature information, but the perforation in the middle of the black crystal plate leads to insufficient strength and is prone to breakage.
參見圖9所示，圖9為現有技術溫度探頭的設計一，該溫度探頭凸 出黑晶板，能準確得知溫度資訊，但溫度探頭能夠上下活動，表示溫度探頭與黑晶板之間有縫隙，水會滲進來，雖然結構中有導水的設計，但油垢會卡在間隙中，將活動的溫度探頭給堵死。 Refer to Figure 9, which is the first design of a temperature probe in the prior art. The black crystal board can accurately know the temperature information, but the temperature probe can move up and down, indicating that there is a gap between the temperature probe and the black crystal board, and water will leak in. Although the structure has a water-conducting design, the grease will get stuck in the gap , Block the active temperature probe.
參見圖10，圖10為現有技術溫度探頭的設計二，該溫度探頭與彈性體結合，彈性體再結合黑晶板，溫度探頭能上下活動，整個結構也不會漏水，但彈性體要保持彈性，厚度就不可能太大，而這是廚具，每日清潔是不可少的，彈性體在每日清理中破損的機會很大。 Refer to Figure 10, Figure 10 is the second design of the prior art temperature probe. The temperature probe is combined with an elastic body, and the elastic body is combined with a black crystal plate. The temperature probe can move up and down, and the entire structure will not leak water, but the elastic body must remain elastic , The thickness can not be too large, and this is kitchenware, daily cleaning is indispensable, the chance of damage to the elastomer in the daily cleaning is great.
相較於圖9、圖10，前述之溫度探頭是市面最常見的設計，算是最傳統的結構，溫度探頭直接放黑晶板底下，既沒有良好的接觸，又受機內風機幹擾。 Compared with Figures 9 and 10, the aforementioned temperature probe is the most common design on the market, and it is considered the most traditional structure. The temperature probe is directly placed under the black crystal plate, which has no good contact and is interfered by the fan inside the machine.
因此，我們有必要對這樣一種結構進行改善，以克服上述缺陷。 Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects.

一種電磁爐溫度感測結構的組裝方法，包括如下步驟：1)所述機蓋在由上往下與所述機座結合時，具可撓性的導熱墊壓迫在所述溫度探頭的頂部平面，使溫度探頭與所述導熱墊緊密結合，所述溫度探頭被壓迫從而下沉，壓縮彈簧二向下壓縮，使溫度探頭的下半圓柱懸浮在第一腔體內；2)所述溫度探頭的上半圓柱外部的橡膠保溫管因黑晶板的壓迫而變形，從而將黑晶板和線圈盤之間，溫度探頭上半圓柱外部的空間完全隔離，形成第二腔體；3)在機蓋和機座組合後，第一腔體和第二腔體通過線圈盤的第一通孔相連通，貫穿成一個不受外氣干擾的空間，溫度探頭在其間不會受到外氣影響。 A method for assembling a temperature sensing structure of an induction cooker includes the following steps: 1) When the cover is combined with the base from top to bottom, a flexible thermal pad is pressed against the top plane of the temperature probe, The temperature probe is tightly combined with the thermal pad, the temperature probe is forced to sink, and the second compression spring compresses downward, so that the lower half cylinder of the temperature probe is suspended in the first cavity; 2) the upper part of the temperature probe The rubber insulation tube outside the semi-cylinder is deformed due to the compression of the black crystal plate, thereby completely isolating the space between the black crystal plate and the coil disk, and the space outside the semi-cylinder on the temperature probe, forming a second cavity; 3) in the cover and After the base is assembled, the first cavity and the second cavity are connected through the first through hole of the coil disc, and penetrate into a space that is not interfered by external air, and the temperature probe will not be affected by external air.
根據上述方法完成電磁爐溫度感測結構的組裝後，在對鍋具進行溫度檢測時，其溫度傳遞方式為鍋具→高導熱金屬片→導熱膠→黑晶板→導熱 墊→溫度探頭→溫度感測器，從而對溫度信號進行採集，採集到的資訊由電路板回饋至顯示幕處進行顯示。 After completing the assembly of the temperature sensing structure of the induction cooker according to the above method, when detecting the temperature of the pot, the temperature transmission method is pot → high thermal conductivity metal sheet → thermal glue → black crystal plate → heat transfer Pad→temperature probe→temperature sensor to collect the temperature signal, and the collected information is fed back to the display screen by the circuit board for display.
綜上所述，本發明具有以下有益效果：1)一般鍋具的鍋底，在沒有加厚的情況下，要保持完全平整，是很困難的，而加厚的鍋底不僅重量增加，不利使用，且成本提高也不受商家歡迎，而不平整的鍋底，又無法保證鍋具與黑晶板接觸位置下方的溫度感測器相接觸，本發明通過在黑晶板中央上方黏合固定高導熱金屬片，且該高導熱金屬片高凸於黑晶板，使鍋具置放於電磁爐上，第一個接觸鍋底的部份就是高導熱金屬片，便於對鍋具底部溫度資訊進行採集；2)高導熱金屬片採用為質地較軟的材質，本實施例中的材質為紅銅，從而可以分散鍋具所帶來的重量；3)黑晶板本身就是高導熱材質，其中一面是平整的，當作面材使用，另一面並非平整的，多有壓花印痕，溫度感測器直接接觸，就算有導熱矽脂，也不易完整傳達溫度訊息；本方案採用導熱性高的可撓性導熱墊，貼附在黑晶板底面，當溫度探頭向上壓迫時，可撓性導熱墊會將黑晶板縫隙填滿，使得高導熱金屬片接收到鍋底的溫度，經由黑晶板、可撓性導熱墊、溫度探頭從而達到溫度感測器，最大限度的將溫度訊息傳遞給電路板；4)由於電路板必要的散熱要求，主機殼內的風扇會連續或間歇性運轉，也使用主機殼內充滿不定向氣流，溫度感測器所接收到的溫度訊息，可靠性大有問題；本發明在溫度探頭以壓縮彈簧二懸浮安裝在線圈盤與探頭蓋 板所型成的第一腔體中，並以管狀撓性保溫材料(即橡膠保溫管)包圍在線圈盤與黑晶板之間的溫度探頭外，使得溫度探頭完全不受機蓋與機座內流動氣流的影響，得以將鍋具傳來的溫度訊息，準確傳遞給電路板。 In summary, the present invention has the following beneficial effects: 1) It is very difficult for the bottom of general pots and pans to be completely flat without being thickened. The thickened bottom of the pot not only increases the weight and is unfavorable to use, Moreover, the increase in cost is not welcomed by merchants, and the uneven bottom of the pot cannot ensure that the pot is in contact with the temperature sensor below the contact position of the black crystal plate. , And the high thermal conductivity metal sheet is high on the black crystal plate, so that the pot is placed on the induction cooker. The first part that touches the bottom of the pot is the high thermal conductivity metal sheet, which is convenient for collecting temperature information on the bottom of the pot; 2) High The thermal conductive metal sheet is made of a softer material. The material in this embodiment is red copper, which can disperse the weight of the cookware; 3) The black crystal plate itself is a material with high thermal conductivity, one of which is flat. Used as a surface material, the other side is not flat. There are many embossed marks. The temperature sensor is in direct contact. Even with thermal grease, it is not easy to completely convey the temperature information; this solution uses a flexible thermal pad with high thermal conductivity. Attached to the bottom surface of the black crystal plate, when the temperature probe is pressed upward, the flexible thermal pad will fill the gaps of the black crystal plate, so that the high thermal conductivity metal sheet receives the temperature of the bottom of the pot, and passes through the black crystal plate and the flexible thermal pad , The temperature probe can reach the temperature sensor and transmit the temperature information to the circuit board to the greatest extent; 4) Due to the necessary heat dissipation requirements of the circuit board, the fan in the main chassis will run continuously or intermittently, and also use the main chassis The temperature information received by the temperature sensor is full of non-directional airflow, and the reliability is very problematic; in the present invention, the temperature probe is mounted on the coil disk and the probe cover with two compression springs. In the first cavity formed by the board, the temperature probe between the coil disk and the black crystal board is surrounded by a tubular flexible insulation material (ie rubber insulation tube), so that the temperature probe is completely free from the cover and the base. The influence of the airflow flowing inside can accurately transmit the temperature information from the pot to the circuit board.
