Abstract
The utility model discloses a microwave oven air supply system, including the air intake, arrange the fan between shell and the roof in, with the just right heating tube cover that has the fresh air inlet of fan export, arrange preceding heating pipe and the back heating pipe in the heating tube cover in to and set up on the roof and heat the preceding heating pipe supply-air hole and the back heating pipe supply-air hole that the chamber switched on with food, its characterized in that, be provided with the induced air board of distribution air inlet in the heating tube cover, lead the air respectively to preceding heating pipe and back heating pipe.
Description
The technical field is as follows:
the utility model relates to a small household electrical appliances microwave oven in kitchen, in particular to a microwave oven air supply system.
Background art:
the simple hot air of the existing microwave oven on the market mostly adopts a fan to blow front and back double heaters to form direct through-flow or convection circulation, the heat on the surface of the heaters is transferred to a food heating cavity, air channel guiding drainage is not carried out on the heaters, after the through-flow air is blown, a front heating tube generates wind resistance, after heat exchange is carried out once, the heat flows through a back heater, effective heat exchange cannot be generated on a back heating tube, the temperature of the back heating tube is high, the reliability is low, the back part of a heating tube cover is yellow, and the temperature of a shell is high.
The utility model has the following contents:
the utility model aims to solve the technical problem that a microwave oven air supply system is provided, its technical scheme who adopts is: the utility model provides a microwave oven air supply system, includes the air intake, arranges the fan between shell and roof in, with the just right heating tube cover that has the fresh air inlet of fan export, arranges preceding heating pipe and the back heating pipe in the heating tube cover in to and set up the preceding heating pipe supply-air hole and the back heating pipe supply-air hole that switch on with food heating chamber on the roof, its characterized in that, be provided with the induced air board of distribution air inlet in the heating tube cover, lead the air inlet respectively to preceding heating pipe and back heating pipe.
The utility model discloses further technical characteristic is:
the induced draft plate is arranged on the inner wall of the heating pipe cover.
The air inlet is arranged on the shell.
The utility model has the advantages that:
because the utility model relates to a microwave oven air supply system, including the air intake, arrange the fan between shell and roof, with the fan export just right heating tube cover that has the fresh air inlet, arrange the front heating pipe and the back heating pipe in the heating tube cover to and set up on the roof with the front heating pipe supply-air hole and the back heating pipe supply-air hole of food heating chamber conduction, its characterized in that, be provided with the induced air board of distribution air inlet in the heating tube cover, lead the air inlet respectively to front heating pipe and back heating pipe, can do the wind channel direction to heater surface heat like this, solve shell surface temperature rise, improve heater reliability; the structure improves the uniformity of the food heating cavity, improves the heat efficiency, and can also solve the problems of yellowing of the rear part of the heating pipe cover and high temperature of the shell.
Description of the drawings:
fig. 1 is a perspective view of an embodiment of the present invention.
The specific implementation mode is as follows:
the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, an air supply system of a microwave oven comprises an air inlet 1, a fan 4 arranged between a housing 2 and a top plate 3, a heating pipe cover 5 with an air inlet hole and facing to the outlet of the fan 4, a front heating pipe 6 and a rear heating pipe 7 arranged in the heating pipe cover 5, and a front heating pipe air supply hole 8 and a rear heating pipe air supply hole 9 which are arranged on the top plate 3 and communicated with a food heating cavity 11, and is characterized in that an air guide plate 10 for distributing inlet air is arranged in the heating pipe cover and respectively guides the inlet air to the front heating pipe and the rear heating pipe.
In the present embodiment, the induced draft plate 10 is disposed on the inner wall of the heating pipe cover; the air inlet 1 is arranged on the shell.
Because the utility model relates to a microwave oven air supply system, including air intake 1, locate in the fan 4 between shell 2 and roof 3, with the fan 4 export just right heating tube cover 5 with the fresh air inlet, locate in heating tube cover 5 in front heating pipe 6 and rear heating pipe 7, and set up on the roof and the food heating chamber switch on front heating pipe supply-air vent 8 and rear heating pipe supply-air vent 9, characterized by that, be provided with the induced air board 10 of distribution air inlet in the heating tube cover, lead the air inlet respectively to front heating pipe and rear heating pipe, can do the wind channel direction to the heater surface heat like this, solve the shell surface temperature rise, improve the heater reliability; the structure improves the uniformity of the food heating cavity, improves the heat efficiency, and can also solve the problems of yellowing of the rear part of the heating pipe cover and high temperature of the shell.
While the invention has been described with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the above-described arrangements without departing from the spirit and scope of the invention, including in the combination of features disclosed herein either individually or in any claim herein, and in any other combination which is obvious to be encompassed by such features. These variants and/or combinations fall within the technical field of the present invention and are intended to be protected by the following claims.
