Detailed Description

Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the invention, its application, or uses. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It should be noted that: the relative arrangement of parts and steps, the composition of materials, numerical expressions and numerical values set forth in these embodiments are to be construed as merely illustrative, and not as limitative, unless specifically stated otherwise.

As shown in fig. 1 to 5, in one aspect of the present invention, a food heating unit is provided, which includes a baking tray 1, a heating pipe 2 and a partition plate 3.

Wherein, the upper surface of the baking tray 1 is used for placing food to be heated; the heating pipe 2 is arranged below the baking tray 1 and can generate heat after being electrified; the partition plate 3 is arranged between the baking tray 1 and the heating tube 2, is simultaneously contacted with the baking tray 1 and the heating tube 2, can transmit the heat of the heating tube 2 to the baking tray 1 in a heat conduction mode, and has the thickness not more than 0.5 mm.

The arrangement of the partition plate 3 prevents the baking tray 1 from directly contacting the heating tube 2, and avoids the problem that oil added in food or in the food processing process drips from the baking tray 1 to the heating tube 2 to cause impurities to adhere to the heating tube 2, thereby avoiding the problem that the heating tube 2 generates heating power attenuation due to the impurities adhering to the surface or harmful substances adhere to the food due to long-term oil stain broiling.

Because baffle 3 is as the intermediate medium that heating tube 2 transmitted heat to overware 1, the heat conductivity of baffle 3 will influence the speed that overware 1 heaied up, consequently the utility model provides a heat conductivity coefficient of baffle 3 is not less than 80W mK to make heating tube 2's heat can be faster, conduct more fully for overware 1, improve food heating unit's thermal response speed and thermal efficiency, promote user's use and experience.

And to 1 edge cooler and the hotter problem in overware 1 center often appearing in the baking food process, the utility model discloses set up heating tube 2 and baffle 3's contact position into at least partially just to overware 1 border position to also provide sufficient heat to overware 1 border position, make the temperature homogeneity between 1 edge of overware and the central zone higher, avoid the food baking in-process to appear being in 1 central zone's of overware local already ripe even baking paste, and be in 1 border zone's of overware local still cold state.

However, since the heating pipes 2 distributed linearly are limited to the difference in area between the wire and the surface of the grill pan 1 distributed in a planar manner, and it is difficult to actually overlap or lay the two, the heating pipes 2 are still "discrete" with respect to the directly heated area of the grill pan 1, that is, the area of the grill pan 1 facing the heating pipes 2 is high in temperature, and the area located away from the heating pipes 2 or between the heating pipes 2 is low in temperature. Therefore, even if heat pipe 2 is moved to a position directly below the originally cooler grill pan 1 area, for example, to the edge of grill pan 1, a new cooler grill pan 1 area still appears.

In view of the above, preferably, the present invention selects the partition plate 3 with a higher heat transfer coefficient as the intermediate heat transfer structure, so that the heat transfer coefficient of the partition plate 3 is greater than that of the baking tray 1, and the partition plate 3 and the lower surface of the baking tray 1 are in surface-to-surface contact, thereby further improving the heating uniformity of the baking tray 1.

Specifically, when the heat emitted from the heating tube 2 is transferred to the partition plate 3, the partition plate 3 has a large thermal conductivity and a small thickness, and therefore the heat emitted from the heating tube 2 is almost simultaneously transferred to the position of the grill pan 1 facing the heating tube 2 through the partition plate 3. At this time, since the heat is propagated faster in the partition plate 3 having a higher heat conductivity, the position of the partition plate 3 not in contact with the heating pipe 2 can reach the heating temperature of the heating pipe 2 faster than the position of the upper surface of the grill pan 1 facing the heating pipe 2. Then, partition 3 will itself act as a heat source for grill pan 1, transferring heat to a location of grill pan 1 not directly facing heating tube 2 by giving a larger contact area therebetween through surface-to-surface contact.

It can be seen that the time difference between the temperature rise of the area of the lower surface of bakeware 1 facing heating tube 2 and the temperature rise of the area not facing heating tube 2 will depend on the heat conductivity coefficient of partition plate 3, and when the heat conductivity coefficient of partition plate 3 is large enough, the positions of the lower surface of bakeware 1 will reach the heating temperature in a nearly simultaneous temperature rise state as a whole. Then, grill pan 1 will gradually transfer the heat from the lower surface of grill pan 1 to the upper surface of grill pan 1 and heat the food with its own smaller coefficient of thermal conductivity, and in this process, the non-uniformity of the temperature rise of the lower surface of grill pan 1 will be further weakened by the heat conduction along the plane where grill pan 1 is located, thereby improving the uniformity of the temperature rise of the upper surface of grill pan 1 and making the heating of the baked food more uniform.

Preferably, the upper surface of baking tray 1 is rectangular, and heating pipe 2 includes at least two first pipe sections 21 and at least one second pipe section 22. At least two first pipe sections 21 are attached to the lower surface of the partition plate 3 along the length direction of the baking tray 1 and are arranged in parallel with each other at a set interval; and at least one second pipe section 22 is connected to the ends of two adjacent first pipe sections 21 in the width direction of grate plate 1, so that two first pipe sections 21 are connected end to end.

Preferably, of the at least two first pipe sections 21, the projection of the two outermost first pipe sections 21 on the partition plate 3 at least partially coincides with the projection of the edge of the baking pan 1 in the length direction on the partition plate 3. Therefore, the heating pipe 2 can effectively heat the edge area of the baking tray 1 in the length direction, and the temperature uniformity between the edge area and the central area of the baking tray 1 is improved.

The heating tubes 2 in the M-shaped distribution can improve the distribution density of the heating tubes 2 relative to the partition plates 3 as much as possible while ensuring that the minimum bending radian of the heating tubes 2 meets the standard, thereby further improving the temperature uniformity of the baking tray 1.

Moreover, two free ends of the heating tubes 2 distributed in the M shape are positioned at the same side, so that the heating tubes 2 can be conveniently installed and an electrified circuit can be conveniently arranged.

The third pipe section 23 in the S-shaped structure can prevent the heating tube 2 from being tightly attached to the lower surface of the partition plate 3, but has a certain installation distance in the height direction with the partition plate 3, so that the fixing block 24 can be conveniently arranged on the heating tube 2. And the S-shaped structure has an included angle of alpha degrees at the bending position of the heating tube 2, and the third tube section 23 can be ensured not to be cracked or failed due to bending by making the included angle larger than the allowable value of the bending of the heating tube 2.

Form similar design effect of preventing slow-witted by holding tank 31, can avoid heating tube 2 to make mistakes in the installation, and holding tank 31 can also fix a position heating tube 2 to heating tube 2's the effect of holding, makes heating tube 2 set up the position in the course of the work more stable.

Preferably, the separator 3 further comprises a first raised structure 32 and a second raised structure 33.

The second protrusion structures 33 protrude from the partition 3 to one side of the heat generating tube 2, are located at two sides of the receiving groove 31 for receiving the second tube segment 22 in a group, and are provided with first fixing holes 331; in cooperation therewith, the food heating unit further comprises a pressure plate 4, the pressure plate 4 is provided with two second fixing holes 41, and has a circular arc-shaped groove 42 between the two second fixing holes 41, the second fixing holes 41 can be matched with the first fixing holes 331, so that when the pressure plate 4 is fastened to a set of two second protruding structures 33 by screws, the second tube section 22 is pressed to the partition 3 through the circular arc-shaped groove 42.

Through the cooperation between clamp plate 4 and the second protruding structure 33, can be with heating tube 2 fixed laminating in the bottom surface of baffle 3 more firmly, avoid the clearance between heating tube 2 and the baffle 3 to the adverse effect of heat transfer to improve food heating unit's thermal efficiency.

In another aspect of the present invention, there is provided a food grilling apparatus comprising a housing 5 and a food heating unit according to any of the embodiments above. The top panel 611 of the box 5 is provided with a mounting hole 611a for installing a food heating unit.
