Description
本發明係有關一種可降低回火現象之自然通風免燙傷的瓦斯烤箱，尤指一種兼具可大幅降低回火現象，及重新點火較容易之可降低回火現象之自然通風免燙傷的瓦斯烤箱。 The present invention relates to a natural ventilation and scald-free gas oven which can reduce the tempering phenomenon, in particular to a natural ventilation and scalding-free gas oven that can greatly reduce the tempering phenomenon, and can reduce the tempering phenomenon with easier re-ignition. .
厚片肉排(可為牛排或其他肉排類，例如：豬排…等)廣受全球入士所喜愛，特別是北美地區，非常喜歡在戶外之開放空間烤肉，或稱為戶外燒烤(原文Barbecue)。然而，由於厚片牛排之厚度較大，可能達5公分以上，若以一般攝氏600度以下之明火(若為柴火可達400至600度)直接接觸來烤，經常只能烤熟外皮而內部仍不熟，或是內部熟時外面已燒焦。若以紅外線爐的紅外線來加熱，由於紅外線之穿透性較強，烤出來的效果最好，可以達到內外都熟且肉嫩多汁，對於肉類(厚片肉排)之美食愛好者，這類燒烤設備之需求極高。 Thick sliced steak (can be steak or other meat steaks, such as: pork steak...etc) is widely loved by sushi around the world, especially in North America, who like to grill meat in an outdoor open space, or outdoor barbecue (original Barbecue). However, due to the thickness of the thick-sliced steak, it may be more than 5 cm. If it is grilled directly with an open fire below 600 degrees Celsius (400 to 600 degrees in the case of firewood), often only the outer skin and the inner part are cooked. Still undercooked, or charred on the outside when cooked on the inside. If the infrared ray of the infrared oven is used for heating, due to the strong penetration of the infrared ray, the roasting effect is the best, and the meat can be cooked inside and outside and the meat is tender and juicy. The demand for BBQ equipment is extremely high.
紅外線爐燃燒溫度高達攝氏800度以上，市面上已有許多上火式之紅外線烤爐，若在谷歌(Google)搜尋引擎中輸入英文800 degree grill(中文為800度燒烤)，則有許多現有產品可參考。 The combustion temperature of infrared ovens is as high as 800 degrees Celsius. There are many fire-type infrared ovens on the market. If you enter 800 degree grill in English (800 degree grill in Chinese) in the Google search engine, there are many existing products. available for reference.
參閱第6A圖，此為傳統式之上火式之紅外線烤爐之示意圖。結構可簡化為：一主容室81、一上容室82、一後容室83及一燃料供應部84。該主容室81之前方設有一開口811，該主容室81可供設置一食物承架及一烤盤，該烤盤可放置一厚片肉排(亦即待燒烤之一物體91)。該上容室82設一上火式之紅外線燃燒器821及一文氏管部822；該後容室83設一控制閥831及複數後通氣孔H2。該燃料供應部84設一瓦斯管841及一瓦斯桶842。
Please refer to Figure 6A, which is a schematic diagram of a traditional top-fired infrared oven. The structure can be simplified as: a
該控制閥831用以開啟該瓦斯桶842，透過該瓦斯管841、配合該文氏管部822朝該紅外線燃燒器821供入瓦斯以進行燃燒(公知技術係利用點火針點火)持續燃燒一段時間後，升溫能達到攝氏800度(或更高)，則可產生向下方輻射之紅外線，對厚片肉排加熱。
The
當戶外無風或微風時，整個氣體流動可分為二： When there is no wind or breeze outside, the entire gas flow can be divided into two:
[a]上火式之該紅外線燃燒器821所需之空氣由該後容室83之該複數後通氣孔H2進入，經該文氏管部822與瓦斯混和，再進入上火式之該紅外線燃燒器821中燃燒。
[a] The air required by the
[b]該主容室81之該開口811自然進氣，此時，被加熱之氣體會向上流動，再沿著該開口811之頂緣而自然流出。
[b] The opening 811 of the
但是，參閱第6B圖，若戶外突然有強風A4由該開口811灌入時，此時，火焰會由上火式之該紅外線燃燒器821逆向燃燒，經該文氏管部822及該控制閥831後，最後由最鄰近之該後通氣孔H2冒出火，此現象稱為「回火」。發生回火時，看起十分可怕。更嚴重者若該瓦斯管841及該瓦斯桶842有漏氣，則可能有引爆之可能性。
However, referring to FIG. 6B, if a strong wind A4 is suddenly poured in through the
其次，由於公知點火針設於該主容室81之內部之上方角落區，此部分較不通風，會殘留燃燒後之氣體(如二氧化碳)。若是在燃燒關閉後(短時間內)要重新點火，此角落區因新鮮空氣不足，較不易點火，此亦為缺點。
Secondly, since the conventional ignition needle is located in the upper corner area of the
有鑑於此，必須研發出可解決上述習用缺點之技術。 In view of this, it is necessary to develop a technology that can solve the above-mentioned conventional shortcomings.

In particular, the problem to be solved by the present invention is that the known infrared gas oven may generate backlash when it is poured into the main chamber under strong wind.

In practice, the main chamber S1 is used for placing at least one
該內頂板11、該二內側板12、該內底板13、該第一後板14及該第二後板15係連結成一體結構。

The two
該紅外線燃燒部31可為公知上火式燃燒結構。
The infrared burning
該控制部33可為瓦斯控制閥。
The
本發明係具有下列兩種氣流導引模式： The present invention has the following two airflow guidance modes:
[a]第一種模式：參閱第5A圖，當啟動該控制部33，係開始供入瓦斯A1，使該紅外線燃燒部31開始燃燒，燃燒過程所需之空氣A2至少由該複數包圍板氣孔H5進入該後容室S5，並經該文氏管部32與該瓦斯A1混和，再進入上火式之該紅外線燃燒部31燃燒(此過程為公知技術)，進而對該物體91進行加熱、燒烤，過程中該主容室S1之該前開口H3自然進氣，此時，被加熱之氣體A3向上流動，再沿著前開口H3之頂緣自然流出。
[a] The first mode: Referring to Fig. 5A, when the
此模式的重點在於，該主容室S1接近該上輔助通孔H1的位置，因接近該點火針141，原則上氧氣最先被燃燒而呈現最低量，但由於本發明之該主容室S1、該上輔助通孔H1、該輔助容室S2、該後通氣孔H2、該底容室S4、該後容室S5及該包圍板氣孔H5互呈連通，空氣流通性佳，相對氧氣流通性佳，故即使關閉後短時間內要再進行燒烤，仍可輕易點燃。
The key point of this mode is that the main chamber S1 is close to the upper auxiliary through hole H1. Since it is close to the
[b]第二種模式：參閱第5B圖，而當突然有強風A4(特別是北美地區，非常喜歡在戶外之開放空間烤肉，易有強風A4吹襲)由該前開口H3灌入時，由於該主容室S1、該上輔助通孔H1、該輔助容室S2、該後通氣孔H2、該底容室S4、該後容室S5及該包圍板氣孔H5互呈連通。且重點在於此時該主容室S1朝該上輔助通孔H1的方向呈「低壓」，至於該紅外線燃燒部31朝該主容室S1的方向則呈「高壓」，故該強風A4在灌入該主容室S1後，原則上朝「低壓」方向流動，而可經該上輔助通孔H1、該後通氣孔H2及該包圍板氣孔H5，迅速的分散至該輔助容室S2、該底容室S4及該後容室S5。能減少朝「高壓」方向流動的壓力，進而大幅降低該紅外線燃燒組件30之回火現象。
[b] The second mode: refer to Figure 5B, and when there is a sudden strong wind A4 (especially in North America, who likes to barbecue in an outdoor open space, it is easy to have strong wind A4 blowing) when the front opening H3 is poured in, Because the main chamber S1 , the upper auxiliary through hole H1 , the auxiliary chamber S2 , the rear vent hole H2 , the bottom chamber S4 , the rear chamber S5 and the air hole H5 of the surrounding plate communicate with each other. And the point is that the main chamber S1 is at a "low pressure" in the direction of the upper auxiliary through hole H1, and the infrared burning
又，該外殼體20係用以阻隔而防止直接接觸該主爐體10，達成免燙傷之結構者。
In addition, the
本發明之優點及功效係如下所述： The advantages and effects of the present invention are as follows:
[1]可大幅降低回火現象。本發明除主要進行燒烤之該主容室外，另設計與主容室相連通之該輔助容室、該底容室及該後容室，且於燒烤過程中，該主容室朝該輔助容室的方向呈現「低壓」，而該主容室朝該紅外線燃燒部的方向則呈現「高壓」。一旦有強風灌入該主容室，原則上會朝「低壓」方向流動，而可經該輔助容室、該底容室及該後容室的方向快速分散。減少強風朝該紅外線燃燒部方向流通的壓力，進而大幅降低該紅外線燃燒組件之回火現象。故，可大幅降低回火現象。 [1] The tempering phenomenon can be greatly reduced. In addition to the main chamber for grilling, the present invention also designs the auxiliary chamber, the bottom chamber and the rear chamber which communicate with the main chamber, and during the grilling process, the main chamber faces the auxiliary chamber. The direction of the chamber presents "low pressure", while the direction of the main chamber towards the infrared burning part presents "high pressure". Once a strong wind is poured into the main chamber, in principle, it will flow in the direction of "low pressure", and can quickly disperse in the direction of the auxiliary chamber, the bottom chamber and the rear chamber. The pressure of the strong wind flowing in the direction of the infrared burning part is reduced, thereby greatly reducing the tempering phenomenon of the infrared burning component. Therefore, the tempering phenomenon can be greatly reduced.
[2]重新點火較容易。就理論上而言，該主容室接近該上輔助通孔的位置，因接近該點火針，原則上氧氣最先被燃燒而呈現最低量，本發明針對這部分，設計該主容室、該上輔助通孔、該輔助容室、該後通氣孔、該底容室、該後容室及該包圍板氣孔互呈連通，大幅提高空氣流通性，相對氧氣流通性佳(也可以說是補充快)，即使關閉後短時間內要再進行燒烤，仍可輕易點燃。故，重新點火較容易。 [2] Re-ignition is easier. In theory, the position of the main chamber close to the upper auxiliary through hole, because it is close to the ignition needle, in principle, oxygen is burned first and presents the lowest amount. The upper auxiliary through hole, the auxiliary chamber, the rear ventilation hole, the bottom chamber, the rear chamber and the air hole of the surrounding plate are connected with each other, which greatly improves the air circulation, and the relative oxygen circulation is good (it can also be said to be a supplementary fast), it can be easily ignited even if the grill is to be carried out again after a short period of time after closing. Therefore, re-ignition is easier.
以上僅是藉由較佳實施例詳細說明本發明，對於該實施例所做的任何簡單修改與變化，皆不脫離本發明之精神與範圍。 The above is only to describe the present invention in detail by means of preferred embodiments, and any simple modifications and changes made to the embodiments do not depart from the spirit and scope of the present invention.
