Referring to FIGS. 1 and 4 , the present embodiment provides a tray 100 , which is applied to a cooking device with a micro-bake function. The cooking device includes a magnetron. The tray 100 includes a tray main body 110 , which is supported on the tray main body 110 . A number of slits are opened on the object surface, and the length of the slits is not less than 1/4 of the wavelength of the microwaves emitted by the magnetron. Therefore, when the tray 100 is installed as a structure for carrying ingredients into a cooking device with a micro-baking function, The microwaves emitted from the bottom of the cooking device with the micro-bake function can be coupled from the bottom of the tray 100 to the top of the tray 100 through the gap on the tray body 110 , so that the microwaves can heat the food on the tray 100 .

It should be noted that there are transverse waves and longitudinal waves in the microwaves emitted by the magnetron. Therefore, several groups of linear slits 111 are arranged in the above-mentioned plurality of slits. Among them, there are several first linear slits and several linear slits in the same group of linear slits 111 For the second linear slot, the first linear slot and the second linear slot are set to be perpendicular to each other, so that the coupling effect of the tray 100 on the transverse wave and the longitudinal wave of the microwave can be improved, and furthermore, the utilization rate of the microwave can be improved.

In addition, mesh holes are arranged on the main body of the tray. When the ingredients are placed on the tray 100 and the ingredients are cooked with several functions including the steaming function, the existence of the mesh holes can make the ingredients more fully contact with the steam , it is convenient to improve the heating uniformity of each part of the ingredients, alleviate the problem that the parts of the ingredients are overcooked and the parts are not cooked, and the cooked dishes are more delicious.

Therefore, the tray 100 provided in this embodiment can allow microwaves to pass through, so that when it is placed in a cooking device with a micro-bake function, the cooking device with a micro-bake function can simultaneously micro-dry the ingredients on the tray 100 and roasting, increasing the variety of ingredients that can be cooked, shortening the cooking time and cooking more delicious dishes.

A number of arc-shaped slits 112 can be added in the plurality of slits, and the vertical line on the center of the circle corresponding to the arc-shaped slit 112 is set to be less than 8 mm away from the vertical line at the center of the waveguide input port of the cooking device. In this way, the arc The arc-shaped slot 112 surrounds the vicinity of the vertical line in the center of the waveguide input port of the cooking device, and the microwave density near the vertical line at the center of the waveguide input port of the cooking device is relatively high, so the existence of the arc-shaped slot 112 can be very good. Coupling effect of reflected microwaves.

Specifically, the length range of the linear slot 111 is set to 1/4-1/2 of the wavelength of the microwave emitted by the magnetron. Within this range, the microwave coupling effect through the linear slot 111 on the tray main body 110 is better.

The length of the arc-shaped slot 112 is set to be 1/2-7/8 of the wavelength of the microwave emitted by the magnetron. Within this range, the microwave coupling effect through the arc-shaped slot 112 on the tray main body 110 is better.

Specifically, the width of each slot can be set to be greater than 3 mm, so that the problem of too little microwave coupling above the tray due to too small slot width can be prevented, and the microwave coupling effect can be improved.

As an embodiment, the above-mentioned slits can be arranged symmetrically with respect to the center of the tray main body 110 , which can improve the uniformity of the arrangement of the slits, and the utilization rate of microwaves is higher.

As another possible implementation manner, the above-mentioned slits can be arranged symmetrically with respect to the two symmetry lines of the tray 100 itself, so that the arrangement of the slits is more uniform and the utilization rate of microwaves is higher.

The tray 100 provided in this embodiment can simultaneously have the above two embodiments.

Specifically, the extension line of each linear slot 111 can be set to coincide with the center of the tray 100 , so as to improve the coupling effect of the linear slot 111 on microwaves and improve the utilization rate of microwaves.

Preferably, the length direction of the first straight slit in one group of straight slits 111 is set to be the same as the moving direction of the tray entering the cavity of the cooking device horizontally. In this way, a better coupling effect can be obtained, and the utilization of microwaves higher rate.

Specifically, the above-mentioned first linear slit extending along the moving direction of the tray entering the cavity of the cooking device horizontally is parallel to the side wall of the cavity.

It should be noted that the microwaves entering the cavity 200 of the cooking device with the micro-baking function mainly propagate in a direction parallel to the side wall of the cavity 200 , therefore, at least one first linear slot is horizontally inserted into the cooking device along the tray. By extending the moving direction of the cavity of the device, a better coupling effect can be obtained, and the utilization rate of microwaves is high.

When the cross-section of the cavity 200 of the cooking device with the micro-bake function is a rectangle, the first straight slit is parallel to the two sides of the rectangular cross-section corresponding to the side walls.

When the number of groups of the linear slits 111 is more than two groups, the linear slits 111 in different groups are all arranged at an included angle.

It should be noted that when the microwave is reflected under the blocking of the cavity wall of the cooking device with the micro-baking function, and the propagation direction changes, the straight-line slits 111 in different groups are all arranged at an included angle, which can improve the reflected microwave. coupling effect.

This embodiment takes two groups of linear slits 111 as an example for description: in the two groups of linear slits 111 , the first linear slit in one group of linear slits 111 and the first linear slit in the other group of linear slits 111 It is arranged at an included angle of 45 degrees. Because the first straight slit in one group of straight slits 111 is parallel to the side wall of the cavity along the tray, the first straight slit in the other group of straight slits 111 is parallel to the side wall of the cavity. The walls are at an included angle of 45 degrees, so that more reflected microwaves can be coupled from the bottom of the tray 100 to the top of the tray 100 .

When three groups of straight slits 111 are set, the first straight slit in the newly added group is located on the angle bisector of the first straight slit in the above two groups of straight slits 111 on the basis of the above two groups, that is, the new The first linear slot in the additional group forms an included angle of 22.5 degrees with the side wall of the cavity, so that more reflected microwaves can be coupled from the bottom of the tray 100 to the top of the tray 100 .

When the straight slits 111 are set to four groups, on the basis of the above three groups, the first straight slit in the newly added group is located on the angle bisector of the second straight slit in the above two groups of straight slits 111, that is, the newly added The first straight slit in the group forms an included angle of 22.5 degrees with the side wall of the cavity, and the first straight slits in the two groups of straight slits 111 added later are arranged at an included angle of 45 degrees, so that more The reflected microwaves are coupled from below the tray 100 to above the tray 100 .

It should be noted that the number of groups of the straight slits 111 can continue to be increased. However, too many straight slits 111 will not only have a great impact on the strength of the tray 100 , resulting in a reduction in the carrying capacity of the tray 100 and easy damage; Realization, the processing cost increases.

Specifically, the mesh holes of the tray main body 110 are set as circular holes with diameters between 3mm and 4mm or polygons with side lengths between 3mm and 4mm. In this way, not only can the ingredients be in sufficient contact with the steam, but also the absolute Most of the ingredients are not easy to leak from the mesh holes. Therefore, when cooking a single ingredient with a small volume, it is not necessary to place the ingredients on other utensils, and then place the utensils together on the tray body 110 for cooking. That is, Small-sized ingredients can also be directly placed on the tray main body 110 for cooking.

The shape of the mesh on the tray body 110 is preferably a regular polygon.

Correspondingly, the width of the gap on the tray main body 110 is also set to be between 3 mm and 4 mm, so that the probability of the ingredients leaking from the gap can be reduced.

Since the cross section of the cavity 200 of the cooking device with the micro-bake function is generally rectangular, the tray 100 is set to be rectangular, so that the tray 100 is better suited for the cooking device with the micro-bake function.

Referring to FIGS. 2 to 5 , the tray 100 provided in this embodiment further includes a ring-shaped support frame 120 , and the edge of the tray body 110 can be fixedly connected to the support frame 120 .

Further, a support bar 130 can be provided on the tray 100, the support bar 130 can be fixed under the tray main body 110, and the two ends of the support bar 130 can be fixedly connected to the opposite sides of the support frame 120 respectively. In this way, the support bar 130 can lift the bottom of the tray main body 110, which can alleviate the problem of the tray main body 110 sinking downward.

Specifically, the support frame 120 is made of metal to adapt to the high temperature and high humidity environment in the cavity 200 of the cooking device.

Referring to FIGS. 2 and 3 , rubber sleeves 140 are sleeved on two opposite frames of the support frame 120 , and the rubber sleeves 140 are used to cooperate with the bosses 210 in the cavity 200 of the cooking device, so that the tray 100 is placed on the During the process of inserting into the cavity 200 of the cooking device, the rubber sleeve 140 of the tray 100 will directly contact the boss 210, while the non-metallic support frame 120 will contact the boss 210. On the one hand, the distance between the tray 100 and the boss can be reduced. Noise generated by the friction between the platforms 210; on the other hand, the occurrence of microwave ignition or the formation of standing waves can also be prevented, thereby improving safety.

Preferably, the above-mentioned rubber cover 140 is provided with a slit extending through the length direction, that is, the rubber cover 140 is a non-closed structure; a number of grooves are arranged on one side of the slit, and on the other side of the slit A plurality of protrusions are arranged on one side, and the grooves and the protrusions are in one-to-one correspondence, and the grooves can be in interference fit with the corresponding protrusions.

When the rubber sleeve 140 needs to be sleeved on the frame of the support frame 120, the slit of the rubber sleeve 140 can face the frame, and then the frame is pressed into the rubber sleeve 140 from the slit, and then each groove In this way, the rubber sleeve 140 and the support frame 120 are matched by interference; when the rubber sleeve 140 needs to be removed from the frame of the support frame 120, the protrusion is directly pulled from the groove. Then, pull the rubber cover 140 to make the rubber cover 140 detach from the frame, which is very convenient for replacement.

Specifically, referring to FIG. 2 and FIG. 5 , the tray body 110 can be configured to have an annular disc wall folded upward from the bottom of the tray. Compared with the tray body 110 without the annular disc wall, the tray body 110 with the annular disc wall It can block the ingredients, prevent the ingredients from falling around, and is more suitable for placing more ingredients.

Referring to FIG. 1 , this embodiment further provides a cooking device with a micro-bake function, which includes the above-mentioned tray 100 .

Therefore, the cooking device with micro-baking function provided in this embodiment may be a cooking device with micro-function and roasting function, such as a micro-baking all-in-one machine, a micro-steaming and roasting machine, etc. The types of ingredients that can be cooked, shorten the cooking time and cook more delicious dishes.
