Abstract
A pivoted heater for a microwave oven is attached to the side of the heating chamber. There is a support to prevent the heater from vibrating when it is turned.
Description
The present invention relates to a kind of rotatable heater of microwave oven, especially a kind of rotatable heater that is used for the microwave oven furnace chamber.
Common microwave stove comprises the conventional microwave oven part and the barbecue grill portion that produce microwave with the food in the heating microwave oven furnace chamber, and the grill heater in the barbecue grill portion utilizes the heat that himself produces that food is roasted.As shown in Figure 1, in the barbecue grill portion, grill heater 3 is arranged on the top of the heating chamber 2 that turntable 1 is housed.Strutting piece 4 is housed on the turntable 1, and grill heater 3 is fixed in the hole of heating chamber 2 sidewalls and with a strutting piece and links to each other.
The working condition of common microwave stove will be described below.The strutting piece 4 of placement being treated food roasting is installed on the turntable 1.After energized and selected grid operator scheme, the grill heater 3 that is fixed on furnace chamber top exhales heat, and the food on the strutting piece 4 is roasted by means of the heat that grill heater 3 produces.Along with the rotation of turntable 1, food is able to even barbecue.
But, in common microwave stove,,, need additional support 4 for making food near grill heater 3 because grill heater 3 is fixed on the top of heating chamber 2.In addition, because food only is simultaneously to be heated to roast, therefore be difficult to realize effective barbecue.In addition, patent documentation GB 2173080A discloses a kind of heater that is used for microwave oven, and wherein heater can rotate between upright position and horizontal level.Another piece patent documentation US 3086102 also discloses a kind of heater that is used for microwave oven, and wherein the two ends of heater are separately fixed on the heating chamber sidewall.Though the heater of GB 2173080A can rotate by means of a supporting construction, structure is comparatively complicated.
Therefore, in order to overcome above-mentioned shortcoming, the purpose of this invention is to provide a kind of microwave oven heater, this heater is rotatably installed in the furnace chamber of microwave oven.
Another object of the present invention provides a kind of rotatable heater for microwave oven simple in structure.
In order to realize purpose of the present invention, the invention provides a kind of rotatable heater for microwave oven, include: one is installed in the heater that is used for heat food in the furnace chamber; This heater is installed in rotation on the fixture on the sidewall of furnace chamber; And the bracing or strutting arrangement that when heater rotates, prevents its vibration.
The present invention is further detailed explanation below in conjunction with drawings and Examples, wherein:
Fig. 1 shows the internal structure of common microwave stove;
Fig. 2 shows the internal structure of heater of the present invention;
Fig. 3 A is the perspective view of the suspension bracket of heater of the present invention;
Fig. 3 B is the installation diagram of the suspension bracket of heater of the present invention;
Fig. 3 C is the decomposition diagram of the fixture of heater of the present invention;
Fig. 4 is the running schematic diagram of heater of the present invention.
2～4 pairs of a preferred embodiment of the present invention are described in detail with reference to the accompanying drawings.
Referring to Fig. 2, grill heater 103 comprises one, and to be arranged on rotating shaft 103a on the straight line that is formed by bracing or strutting arrangement and fixture and one be pivotally supported pivoted arm 103b with rotating shaft 103a.
Shown in Fig. 3 c, the said fixing device comprises a lining 121 and a block set 122, lining is positioned at an end of grill heater 103 and contacts with the madial wall of furnace chamber 101, and block set is used for the lining that the lateral wall upper support at furnace chamber 101 engages with heater, so that heater 103 pivots.
Shown in Fig. 3 A and 3B, bracing or strutting arrangement has a suspension bracket 123 that inserts for heater one end and suspension bracket is fixed to keeper on the furnace chamber madial wall.Suspension bracket 123 has a hole 116, and the rotating shaft 103b of heater inserts wherein.For example, an available screw is as above-mentioned keeper.Suspension bracket 123 is preferably made by bonding jumper and pottery.
In Fig. 2, lining 121 is stepped cylinders, these cylindrical two coaxial settings of cylinder.Furnace chamber wall near lining has stairstepping, so that match with stepped cylinder.The block set of holding lining one end also matches with stepped furnace chamber wall.
For the rotation of control heater 103, above-mentioned block set have the recess 119 and 119 of the projection of selectively inserting on the furnace chamber lateral wall 118 '.
Be used to reduce the bush face 117 that hot-fluid leaks and be set at the furnace chamber inner surface that contacts with the ladder shoulder block 102 of lining.
To the working order of the above embodiment of the present invention be described below.
As shown in Figure 4, the main operation of present embodiment is that heater 103 is rotated up and down, so that heater 103 food to be roasted.When heater 103 begins upwards to rotate, deviate from the recess 119 of projection 118 on block set 122.When heater 103 rotates 90 °, projection 118 enter groove 119 ', with heater 103 location.
When heater 103 rotates down, enter groove 119 from the projection 118 of the recess 119 of block set 122 ' deviate from, heater 103 is positioned on the converted position.
If heater 103 has only end location, heater possibility severe vibration, so suspension bracket 123 is linked to each other with the heater other end, to prevent the heater vibration.
Owing to have forming surface 117 in the junction of lining 121, can prevent microwave leakage.
As mentioned above, because heater is mounted to and can rotates, the present invention can roast effectively.In addition, the present invention has reduced the quantity of parts, and is easy to assembly and can prevent microwave leakage.
