The utility model has simple and reasonable structure, as the outer surface of the quartz pipe is coated with the optical film which is golden yellow and has the temperature resistance of 800 DEG C, the optical film can only be penetrated by visible light and infrared light with a wavelength of 750nm to 16Mum, the penetration of the infrared light within the wavelength range is strong. Therefore, when in application of the utility model for food barbecue, the efficiency is 2 times higher than a common quartz heating pipe, the cooking time is shortened and the energy consumption is reduced. The microwave oven has more energy conservation and environmental protection, as well as longer service life after using the light wave pipe. The light collecting cover can effectively improve the thermal efficiency of the light wave pipe and foods can be baked more evenly.

Description

Micro-wave oven

Technical field

The utility model relates to a kind of micro-wave oven.

Background technology

Infrared ray be have fuel factor, the invisible light of naked eyes, wavelength is 0.75～1000 μ m, its medium wavelength 0.76～1.5 μ m is called short infrared, the about 5～10mm of its penetrate tissue degree of depth (being the depth capacity that fuel factor can reach); Wavelength is the long-wave infrared that is called of 1.5～400 μ m, and its penetration depth is less than 2mm.The advantage of short infrared is that its penetration capacity is 3～5 times of long-wave infrared.In the prior art, the micro-wave oven of band baking function is provided with quartz heating-pipe, is packaged with the metal heating wire in the pipe, utilizes the infrared ray that produces in the metal heating wire galvanization that food in the stove is roasted.The infrared ray that the metal heating wire produces in the heating process mostly is long-wave infrared greatly, causes long, shortcoming such as the thermal efficiency is low of heating-up time.While metal heating wire very easily oxidation blows, and causes heat-generating pipe shorter service life.This in addition heat-generating pipe in use can cause light pollution to a certain degree, harm user's health.

China Patent No. 200420093708.8 provides a kind of charcoal fiber grill microwave oven, the furnace chamber that comprises the shell body, circuit controling assembly and the ccontaining food that form monnolithic case, the furnace chamber top is equipped with the carbon fiber bar heat-generating pipe by being connected and fixed device, described carbon fiber bar heat-generating pipe is electrically connected with the related circuit Control Component, and reflecting plate is housed behind the heat-generating pipe.In the course of work, reflecting plate absorbs the heat of a part, reduces the thermal efficiency of heat-generating pipe.

China Patent No. 200420054494.3 provides the saturating infrared ray halogen of a kind of plated film heating tube, it has quartz ampoule, all there are molybdenum sheet and molybdenum rod in its two ends, METAL HEATING PROCESS silk and support thereof are arranged in the quartz ampoule and be filled with halogen gas, the outer surface of quartz ampoule have outward appearance be golden yellow, heat-resisting reach 800 ℃, can see through that liquid is long to be the blooming of 750nm～16 μ m light, this blooming is made of at least five layers of plated film.Be packaged with the METAL HEATING PROCESS silk in the above-mentioned quartz ampoule, the infrared penetration ability that the METAL HEATING PROCESS silk produces is lower, the easy oxidation of metal heating wire simultaneously, and service life is short.

The utility model content

The purpose of this utility model be intended to provide a kind of simple and reasonable, the thermal efficiency is high, energy-conserving and environment-protective, long service life, the uniform micro-wave oven of baking, to overcome weak point of the prior art.

A kind of micro-wave oven by this purpose design, comprise cavity, be provided with optical wave tube and snoot thereof on cavity top, optical wave tube by quartz ampoule, be packaged in the pipe in calandria and arrangements of electric connection form, it is characterized in that described optical wave tube is halogen heating tube or carbon fibre heating tube.

Bar-shaped, tubulose, cored screw shape or the rope form of the calandria of described carbon fibre heating tube for being woven into by the carbon fibre heater strip.

The outer surface of described quartz ampoule is coated with blooming.Blooming is that outward appearance is golden yellow, heatproof reaches 800 ℃, can only see through the 750nm～visible light of 16 mum wavelengths and the blooming of infrared light.Described blooming is made of at least five layers of plated film.

The individual layer of described plated film is a kind of in calcirm-fluoride plated film, aluminum fluoride plated film, zirconium fluoride plated film, plating aluminium oxide film, silica plated film, titanium oxide filming, magnesia plated film, yittrium oxide plated film, iron oxide plated film or the silicon plated film.

Described plated film is plated film, electroplating film, vacuum coating, thermal evaporation plated film or gas phase plated film.

Described snoot one or both sides are provided with L shaped optical wave tube geometrical clamp.

Be filled with inert gas in the described carbon fibre heating tube.

The utility model is simple and reasonable, because the quartz ampoule outer surface is coated with and is golden yellow, heatproof and reaches 800 ℃ blooming, make it can only see through the visible light and the infrared light of 750nm～16 mum wavelengths, because the infrared light penetration capacity of this wavelength period is strong, so its efficient is than the high twice of common quartz heating tube when being applied in the food barbecue, shorten the cooking time, cut down the consumption of energy.Micro-wave oven energy-conserving and environment-protective more after using this optical wave tube, longer service life.Snoot can effectively improve the thermal efficiency of optical wave tube, and cooking food is more even.
