Embodiment 1

[0047] figure 2 It is a structural schematic diagram of the upper cover in Embodiment 1 of the shell of the microwave oven of the present invention. The upper cover 100 is arranged on the top of the microwave oven, and is used to protect the electronic components in the electric control room of the microwave oven and form the top appearance of the microwave oven. Such as figure 1 As shown, the width D of the upper cover 100 is 27 inches, and the width D is suitable for the size of the kitchen furniture on which the microwave oven is installed. Several screw holes 110 for connecting fixing screws S are formed on the four sides of the upper cover 100 .

[0048] The manufacturing process of the above-mentioned 27-inch upper cover 100 is as follows:

[0049] Firstly, a mold for making the upper cover 100 is manufactured. At this point, the mold had a width of not only 27 inches, but also 30 inches. That is to say, the mold is a 30-inch mold whose interior includes a 27-inch ...

Embodiment 2

[0051] image 3 It is a schematic structural view of the upper cover in Embodiment 2 of the shell of the microwave oven of the present invention; as image 3 As shown, the upper cover 150 includes: a main cover 160 with a width of 27 inches and a secondary cover 170 with a width of 3 inches connected to the right side of the main cover 160; therefore, the overall width of the upper cover 150 for 30 inches. Screw holes 160 a and 170 a are respectively formed on peripheral edges of the main cover 160 and the secondary cover 170 .

[0052] The manufacturing process of the 30-inch upper cover 150 can be as follows: firstly, the main cover 160 and the auxiliary cover 170 are made respectively, and then the main cover 160 and the auxiliary cover 170 are combined to make the rear 30-inch upper cover 150 . The process of making the main cover 160 and the secondary cover 170 will be described respectively below:

[0053] First, a mold for making the main cover 160 is manufactured. ...

Embodiment 3

[0056] Figure 4 It is a structural schematic diagram of the upper cover in Embodiment 3 of the shell of the microwave oven of the present invention; Figure 5 It is a schematic diagram of the combined state of the main cover and the secondary cover in the casing of the microwave oven of the present invention. Refer below Figure 4 and Figure 5 The process of combining the main cover 160 and the secondary cover 170 is described as follows:

[0057] Figure 4 The back side of the upper cover 150 is shown. Such as Figure 4 As shown, the upper cover 150 includes: a main cover 160 formed on the left and a secondary cover 170 connected to the right of the main cover 160 ; a connecting part is provided between the main cover 160 and the secondary cover 170 .

[0058] The main cover 160 has a planar part 161, and within the scope of the planar part 161, there is a concave part recessed toward the back of the main cover; moreover, the edge of the planar part 161 is formed with...

Abstract

The invention discloses a case of microwave oven, which comprises the following parts: front panel, upper lid, rear cover and chassis, wherein the front panel is set in front of the microwave oven to protect the front cavity; the upper lid is set on the top of microwave oven to form the top appearance; rear cover is set on the back of cavity to form back appearance; the chassis is set at the bottom of cavity to form the bottom appearance; the upper lid, rear cover and chassis is irrelative to dimension, which can be manufactured in the same mould. The 27 inch and 30 inch case can be manufactured in one mould, which reduces the cost of mould and microwave oven. The whole dimension of case varies along the quantity and dimension of assistant case, which simplifies the making procedure and shortens the assemblage time.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a shell of the microwave oven. Background technique [0002] As we all know, a microwave oven is a household appliance that uses microwaves generated by a magnetron to heat and cook food. According to its installation location, microwave ovens can be divided into the following two types: one is an ordinary microwave oven used on kitchen furniture; According to the opening and closing method of the furnace door, microwave ovens can be divided into the following two types: one is the microwave oven with side opening and closing of the furnace door; [0003] figure 1 It is a schematic diagram of the structure decomposition of an existing common microwave oven; refer to the following figure 1 A conventional oven door side opening and closing type microwave oven is specifically described. [0004] Such as figure 1 As shown, the microwave oven includes: a body assembly 10 disposed inside the mi...
