请参阅图1～图3，本发明实施方式的烤箱100包括腔体10及发热管组件12。Referring to FIGS. 1 to 3 , an oven 100 according to an embodiment of the present invention includes a cavity 10 and a heat pipe assembly 12 .
腔体10上开设有第一通孔14。发热管组件12开设有与第一通孔14相配的第二通 孔16。发热管组件12通过紧固件(图未示)穿过第一通孔14与第二通孔16而固定至腔体10上。A first through hole 14 is defined in the cavity 10. The heat pipe assembly 12 is provided with a second pass that matches the first through hole 14 Hole 16. The heat pipe assembly 12 is fixed to the cavity 10 through a first through hole 14 and a second through hole 16 by fasteners (not shown).
上述烤箱100中，通过紧固件将发热管组件12固定至腔体10。例如，第一通孔14及/或第二通孔16可为螺孔，紧固件可为螺钉，发热管组件12通过螺钉固定至腔体10上。又如，发热管组件12也可以通过铆接的方式固定至腔体10上。In the above oven 100, the heat pipe assembly 12 is fixed to the cavity 10 by fasteners. For example, the first through hole 14 and/or the second through hole 16 may be a screw hole, the fastener may be a screw, and the heat pipe assembly 12 is fixed to the cavity 10 by screws. As another example, the heat pipe assembly 12 can also be fixed to the cavity 10 by riveting.
也就是说，在安装发热管组件12时，无需预先在腔体10上焊接金属件。因此，腔体10避免了因测试金属件与腔体10的焊接处的寿命而出现爆瓷的现象。That is, when the heat pipe assembly 12 is mounted, it is not necessary to weld the metal member to the cavity 10 in advance. Therefore, the cavity 10 avoids the phenomenon of blasting due to the life of the welded portion of the test metal member and the cavity 10.
请参阅图4～图6，本实施方式中，腔体10包括底板18。发热管组件12包括第一发热管20。第一发热管20设置在底板18上且位于腔体10外。Referring to FIGS. 4-6 , in the present embodiment, the cavity 10 includes a bottom plate 18 . The heat pipe assembly 12 includes a first heat pipe 20. The first heat pipe 20 is disposed on the bottom plate 18 and outside the cavity 10.
如此，由于第一发热管20位于腔体10外，因此，用户在清洗腔体10的时候触碰不到第一发热管20。这样可方便用户清洗腔体10，并使烤箱100更加美观。Thus, since the first heat pipe 20 is located outside the cavity 10, the user does not touch the first heat pipe 20 while cleaning the cavity 10. This makes it easy for the user to clean the cavity 10 and make the oven 100 more aesthetically pleasing.
本实施方式中，较佳地，第一发热管20与底板18接触。In the present embodiment, preferably, the first heat generating tube 20 is in contact with the bottom plate 18.
如此，第一发热管20将产生的热量直接传递到底板18。底板18再将热量传递到腔体10内加热食物。这样可以减少第一发热管20传递到腔体10内的热量损失，从而提高第一发热管20的热量传递效率，进而提高烤箱100对食物的加热效率。As such, the first heat pipe 20 transfers the generated heat directly to the bottom plate 18. The bottom plate 18 then transfers heat to the cavity 10 to heat the food. This can reduce the heat loss transferred from the first heat pipe 20 into the cavity 10, thereby improving the heat transfer efficiency of the first heat pipe 20, thereby improving the heating efficiency of the oven 100 for food.
本实施方式中，腔体10包括相对设置的两个侧板22，两个侧板22连接底板18，底板18及两个侧板22均为金属件。In this embodiment, the cavity 10 includes two opposite side plates 22, and the two side plates 22 are connected to the bottom plate 18. The bottom plate 18 and the two side plates 22 are all metal members.
如此，第一发热管20可将热量通过底板18传递到腔体10的两个侧板22上，两个侧板22再将热量传递给腔体10内的气体，这样可在腔体10内形成均匀的加热场，有利于将放置在腔体10内的食物加热均匀。As such, the first heat pipe 20 can transfer heat to the two side plates 22 of the cavity 10 through the bottom plate 18, and the two side plates 22 transfer heat to the gas in the cavity 10, so that the heat can be generated in the cavity 10. Forming a uniform heating field facilitates uniform heating of the food placed within the cavity 10.
较佳地，底板18与两个侧板22为一体成型结构。Preferably, the bottom plate 18 and the two side plates 22 are integrally formed.
如此，底板18及两个侧板22的制造过程简单，并且可以减少烤箱100的零件数量，从而优化烤箱100的制造流程。As such, the manufacturing process of the bottom plate 18 and the two side plates 22 is simple, and the number of parts of the oven 100 can be reduced, thereby optimizing the manufacturing process of the oven 100.
例如，底板18与两个侧板22可用板件通过冲压工艺冲压形成。底板18与两个侧板22构成U形板。For example, the bottom plate 18 and the two side panels 22 may be stamped by a stamping process. The bottom plate 18 and the two side plates 22 constitute a U-shaped plate.
本实施方式中，发热管组件12包括罩板24。罩板24设置在底板18上且位于腔体10外。罩板24开设有第二通孔16。第一发热管20设置在罩板24与底板18限定的空间内。In the present embodiment, the heat pipe assembly 12 includes a cover plate 24.

The heat pipe assembly 12 includes a second heat pipe 34. The second heat pipe 34 is disposed on the top plate 32 and located within the cavity 10.
如此，烤箱100通过增多加热元件，可提高烤箱100的加热效率。另外，第二发热管34位于腔体10内，这样第二发热管34可直接与腔体10内的气体进行热量交换，从而快速提升腔体10内的温度。As such, the oven 100 can increase the heating efficiency of the oven 100 by increasing the number of heating elements. In addition, the second heat generating tube 34 is located in the cavity 10, so that the second heat generating tube 34 can directly exchange heat with the gas in the cavity 10, thereby rapidly increasing the temperature inside the cavity 10.
第二发热管34的安装方式与第一发热管20的安装方式类似，第二发热管34的安装方式请参考第一发热管20的安装方式，在此不再赘述。The mounting manner of the second heat generating tube 34 is similar to that of the first heat generating tube 20. For the mounting manner of the second heat generating tube 34, refer to the mounting manner of the first heat generating tube 20, and details are not described herein again.

具体地，照明灯36位于腔体10内的边角处。如此，照明灯36不会影响食物的位置。照明灯36可在烤箱100在烘烤食物时对腔体10内进行照明，以使用户通过烤箱100透明的门体观察食物的烘烤过程。Specifically, the illuminator 36 is located at a corner within the cavity 10. As such, the illuminator 36 does not affect the location of the food. The illuminator 36 can illuminate the interior of the cavity 10 while the oven 100 is baking the food to allow the user to observe the baking process of the food through the transparent door of the oven 100.
请一并参阅图1及图7，本实施方式中，进一步地，烤箱100包括壳体38及隔热件40。壳体38设置在腔体10外。隔热件40设置在于壳体38及腔体10之间。Referring to FIG. 1 and FIG. 7 together, in the embodiment, the oven 100 further includes a casing 38 and a heat insulating member 40. The housing 38 is disposed outside of the cavity 10. The heat insulator 40 is disposed between the housing 38 and the cavity 10.
如此，隔热件40可以减少腔体10与外部空气发生热量交换，从而提高烤箱100的加热效率，同时，也能避免壳体38过高的温度对人体造成伤害。In this way, the heat insulating member 40 can reduce the heat exchange between the cavity 10 and the outside air, thereby improving the heating efficiency of the oven 100, and at the same time, avoiding the damage of the human body caused by the excessive temperature of the casing 38.
本实施方式中，隔热件40包括隔热棉。In the present embodiment, the heat insulating member 40 includes heat insulating cotton.
如此，隔热棉具有良好的隔热效果，并且成本较低，容易获取。In this way, the insulating cotton has good heat insulation effect and is low in cost and easy to obtain.
本实施方式中，进一步地，烤箱100包括固定在腔体10的外侧面42上的隔板44，隔板44将隔热件40固定在腔体10的外侧面42上。In the present embodiment, further, the oven 100 includes a partition 44 fixed to the outer side surface 42 of the cavity 10, and the partition 44 fixes the heat insulating member 40 to the outer side surface 42 of the cavity 10.
如此，隔板44可防止隔热件40从腔体10上脱落。As such, the partition 44 prevents the heat insulator 40 from coming off the cavity 10.
具体地，外侧面42为侧板22的外侧面，隔热件40放置到腔体10的外侧面42后，先用隔板44将隔热件40夹紧，然后通过螺钉将隔板44及隔热件40一起固定在侧板22上。Specifically, the outer side surface 42 is the outer side surface of the side panel 22, and after the heat insulating member 40 is placed on the outer side surface 42 of the cavity 10, the heat insulating member 40 is first clamped by the partition 44, and then the partition 44 is screwed and The heat insulating members 40 are fixed together on the side plates 22.
请参阅图4，本实施方式中，进一步地，壳体38包括前板46。前板46设置在腔体10上。前板46上设置有旋钮48，旋钮48用于控制第一发热管20及第二发热管34的温度。Referring to FIG. 4, in the present embodiment, further, the housing 38 includes a front plate 46. The front plate 46 is disposed on the cavity 10. The front plate 46 is provided with a knob 48 for controlling the temperatures of the first heat generating tube 20 and the second heat generating tube 34.
如此，用户通过旋钮48控制第一发热管20及第二发热管34的温度，从而可调节腔 体10内的温度，这样可满足用户对食物进行不同的烘烤需求。In this way, the user controls the temperature of the first heating tube 20 and the second heating tube 34 through the knob 48, thereby adjusting the cavity. The temperature within the body 10 is such that the user can have different baking requirements for the food.
另外，旋钮48还可用于控制烤箱100的工作时间。也就是说，用户可通过旋钮48对烤箱100进行工作定时。如此，用户在烘烤食物的时候无需留意食物烘烤时间的长短，使用方便。Additionally, the knob 48 can also be used to control the operating time of the oven 100. That is, the user can time the oven 100 through the knob 48. In this way, the user does not need to pay attention to the length of the food baking time when baking the food, and is convenient to use.
本实施方式中，进一步地，烤箱100包括设置在腔体10上的风扇52。风扇52用于向腔体10内吹风以使腔体10内的气体流动。In the present embodiment, further, the oven 100 includes a fan 52 disposed on the cavity 10. Fan 52 is used to blow air into cavity 10 to allow gas within chamber 10 to flow.
如此，风扇52有利于使腔体10内形成均匀的加热场，从而有利于食物的烘烤。As such, the fan 52 facilitates the formation of a uniform heating field within the cavity 10 to facilitate bake of the food.
具体地，靠近第一发热管20及第二发热管34的气体温度较高，而远离第一发热管20及第二发热管34的气体的温度较低。风扇52向腔体10内吹风后，靠近第一发热管20及第二发热管34的气体向远离第一发热管20及第二发热管34的地方流动，而远离第一发热管20及第二发热管34的气体向第一发热管20及第二发热管34流动，并与第一发热管20及第二发热管34换热后自身的温度升高。如此循环，最后使腔体10内形成均匀的加热场。Specifically, the temperature of the gas adjacent to the first heat generating tube 20 and the second heat generating tube 34 is higher, and the temperature of the gas away from the first heat generating tube 20 and the second heat generating tube 34 is lower. After the fan 52 blows into the cavity 10, the gas adjacent to the first heat generating tube 20 and the second heat generating tube 34 flows away from the first heat generating tube 20 and the second heat generating tube 34, and away from the first heat generating tube 20 and the first The gas of the two heat generating tubes 34 flows into the first heat generating tubes 20 and the second heat generating tubes 34, and the temperature of the first heat generating tubes 20 and the second heat generating tubes 34 increases.
