Description

Technical Field

[0001] The utility model relates to the technical field of industrial microwave ovens, and specifically relates to an insulating cover for an industrial microwave oven. Background Art

[0002] An industrial microwave oven refers to a microwave oven used for industrial production and processing, and is widely used for heating, drying or sterilizing products such as food and chemicals. For a tunnel-type industrial microwave oven, when processing thin-sheet foods, the product has a thin thickness and a small volume, so the space inside the microwave oven is relatively large, and the heat of the food is easily dissipated, which will affect both the heating efficiency and the drying speed. If you want to reduce the heat dissipation and improve the heating efficiency, usually the way of increasing the heating temperature is adopted, but this way will increase the energy consumption of the microwave oven, thus virtually increasing the production cost. At the same time, when the product inside the microwave oven has completed the heating process but the next process is not carried out in time, if the microwave oven is turned off, the product temperature will drop rapidly and cannot meet the temperature requirements of the next process. If the microwave oven is kept on, it will increase the production energy consumption or the product will overheat. Content of the Utility Model

[0003] In order to solve the technical problems of easy heat dissipation of small-volume foods and large energy consumption of the microwave oven in the above background art, the utility model provides an insulating cover for an industrial microwave oven.

[0004] The technical solution of the utility model is as follows:

[0005] An insulating cover for an industrial microwave oven includes a horizontally placed connecting frame and a support frame movably arranged thereon, and a heat-insulating cloth is connected to the support frame; the connecting frame includes a horizontally arranged connecting rod and support rods at both ends thereof; the support frame includes an arched frame with an opening downward and located below the heat-insulating cloth, and a ring-shaped member passing through the heat-insulating cloth is arranged on the side of the arched frame away from the opening; a plurality of groups of the support frames are arranged in parallel, and the connecting rod passes through the ring-shaped members of the plurality of groups of the support frames.

[0006] Connect and fix the support rods on the inner walls at both ends of the tunnel-type industrial microwave oven, pass the heat-insulating cloth through the ring-shaped member and lay it on the upper side of the arched frame, then pass the connecting rod through the ring-shaped members of several heat-insulating cloths that have been connected in sequence, and finally connect the two ends of the connecting rod to the support rods respectively. The heat-insulating cloth, the support frame and the connecting frame jointly enclose a heat-insulating tunnel, and the product inside the microwave oven is always in the heat-insulating tunnel, reducing the space around the product, reducing heat loss, improving the heat preservation performance at the same time, and reducing the energy consumption of the microwave oven.

[0007] Further, a plurality of the ring-shaped members are arranged along the length direction of the arched frame, increasing the connection points with the heat-insulating cloth and improving the connection stability between the heat-insulating cloth and the arched frame.

[0008] Preferably, the width of the heat-insulating cloth perpendicular to the length direction of the connecting rod is not less than the length of the bow-shaped frame, and the length along the length direction of the connecting rod is not less than 4 / 5 of the length of the connecting rod. This ensures that the size of the heat-insulating cloth is sufficient to cover the products in the microwave oven and guarantees its stable heat-insulating performance.

[0009] As a preferred embodiment, the bow-shaped frame is set as a stainless-steel arc plate with an elastically variable radian. The high-temperature resistant material ensures its safe use in the microwave oven. At the same time, the elastically variable radian can adapt to products with different quantities and sizes in the oven.

[0010] Further preferably, a blind groove is provided on the upper side of the support rod, and the end of the connecting rod is placed in the blind groove. The connecting rod and the support rod are connected through the blind groove, which facilitates the installation and removal of the connecting rod. At the same time, the blind groove has a limiting effect on the connecting rod, preventing it from shifting during the adaptation process.

[0011] Furthermore, several blind grooves are provided along the length direction of the support rod, which can freely adjust the position of the connecting rod in the microwave oven according to the usage conditions.

[0012] Preferably, the inner diameter of the annular member is not greater than 1.5 times the diameter of the connecting rod. While ensuring that the connecting rod can freely pass through the annular member, it avoids waste of raw materials caused by too large a size of the annular member. At the same time, it avoids greater damage to the heat-insulating cloth when the annular member passes through the heat-insulating cloth, resulting in heat loss.

[0013] As a preferred embodiment, the support rod is horizontally arranged perpendicular to the connecting rod. The support rod and the connecting rod are perpendicularly arranged, and the planes where they are located are parallel to each other, increasing the stability between the support rod and the connecting rod and avoiding the situation where the connecting rod tilts to one side.

[0014] Through the above design, the beneficial effects of the present utility model are as follows:

[0015] 1) The heat-insulating cloth, the support frame, and the connecting frame jointly enclose a heat-insulating tunnel. The products in the microwave oven are always in the heat-insulating tunnel, reducing the space around the products, minimizing heat loss. At the same time, as the space around the products decreases, both the heating efficiency and the heat-insulating performance are enhanced, reducing the energy consumption of the microwave oven.

[0016] 2) The arrangement of several annular members on the bow-shaped frame and several grooves on the support rod enables the free adjustment of the position of the connecting rod and the coverage range of the heat-insulating cloth when facing products with different quantities and sizes.

[0025] Embodiment

[0026] Combined with Figures 1 to 4 , this embodiment provides an industrial microwave oven heat-insulating cover, which includes a horizontally placed connecting frame 1 and a support frame 2 movably arranged thereon, and a heat-insulating cloth 3 is connected to the support frame 2. The heat-insulating cloth 3, the support frame 2 and the connecting frame 1 jointly enclose a heat-insulating tunnel, and the products in the microwave oven are always in the heat-insulating tunnel, reducing the space around the products, reducing heat loss, and improving the heating effect and heat-insulating performance.

[0027] In this embodiment, the connecting frame 1 includes a horizontally arranged connecting rod 11 and support rods 12 at both ends.

[0028] Further preferably, a blind groove 121 is provided on the upper side of the support rod 12, and the end of the connecting rod 11 is placed in the blind groove 121. The connecting rod 11 and the support rod 12 are connected through the blind groove 121, which is convenient for the installation and taking of the connecting rod 11. At the same time, the blind groove 121 has a limiting effect on the connecting rod 11 to prevent it from shifting during adaptation.

[0029] Furthermore, a plurality of blind grooves 121 are provided along the length direction of the support rod 12, and the position of the connecting rod 11 in the microwave oven can be freely adjusted according to the use conditions.

[0030] In another specific embodiment, a plurality of connecting rings are provided on the upper side of the support rod 12, and the end of the connecting rod 11 passes through the connecting rings.

[0031] As a preferred embodiment, the support rod 12 is horizontally arranged perpendicular to the connecting rod 11. The support rod 12 and the connecting rod 11 are arranged perpendicular to each other, and the planes where the two are located are parallel to each other, which increases the stability between the support rod 12 and the connecting rod 11 and prevents the connecting rod 11 from tilting to one side.

[0032] In this embodiment, the support frame 2 includes a bow-shaped frame 21 which opens downward and is located at the lower side of the thermal insulation cloth 3 .

[0033] As a preferred embodiment, the bow frame 21 is configured as a stainless steel arc plate with an elastically variable curvature. The high temperature resistant material ensures its safe use in a microwave oven, and the elastically variable curvature can adapt to products of different quantities and sizes in the oven.

[0034] Specifically, both ends of the bow frame 21 are configured to be rounded to avoid wear of the insulation cloth 3 during installation or removal, thereby increasing its service life.

[0035] In this embodiment, a ring-shaped member 22 passing through the thermal insulation cloth 3 is provided on the side of the bow-shaped frame 21 facing away from the opening. In a specific implementation, a plurality of the ring-shaped members 22 are provided along the length direction of the bow-shaped frame 21, thereby increasing the connection points with the thermal insulation cloth 3 and improving the connection stability between the thermal insulation cloth 3 and the bow-shaped frame 21.

[0036] Preferably, the width of the insulation cloth 3 perpendicular to the length direction of the connecting rod 11 is not less than the length of the bow frame 21, and the length along the length direction of the connecting rod 11 is not less than 4 / 5 of the length of the connecting rod 11. Ensure that the size of the insulation cloth 3 is sufficient to cover the product in the microwave oven and ensure its stable insulation performance.

[0037] In a specific implementation, the thermal insulation cloth 3 is provided with a plurality of elastic holes 31 for the ring part 22 to pass through, and the maximum diameter of the elastic hole 31 matches the diameter of the ring part 22. After the ring part 22 passes through the elastic hole 31 smoothly, the inner wall of the elastic hole 31 is always tightly fitted with the outer wall of the ring part 22, thereby reducing heat loss at the connection between the ring part 22 and the thermal insulation cloth 3.

[0038] In this embodiment, the support frames 2 are provided in multiple groups in parallel, and the connecting rods 11 are provided through the annular members 22 of the multiple groups of the support frames 2 .

[0039] Preferably, the inner diameter of the annular member 22 is not greater than 1.5 times the diameter of the connecting rod 11. While ensuring that the connecting rod 11 can freely pass through the annular member 22, it is avoided that the annular member 22 is too large to cause a waste of raw materials, and it is also avoided that the annular member 22 causes significant damage to the insulation cloth 3 when passing through the insulation cloth 3, causing heat loss.

[0040] In specific implementation, the length of the support rod 12 is not greater than the width inside the microwave oven and not less than 4 / 5 of the width inside the microwave oven, ensuring the smooth installation of the support rod 12 and a large coverage range of the bow-shaped frame 21 and the heat-insulating cloth 3.

[0041] Connect and fix the support rod 12 on the inner walls at both ends of the tunnel-type industrial microwave oven. The heat-insulating cloth 3 passes through the annular member 22 and is laid on the upper side of the bow-shaped frame 21. Then, the connecting rod 11 passes through several annular members 22 that have been connected to the heat-insulating cloth 3 in sequence. Finally, both ends of the connecting rod 11 are respectively connected to the support rod 12. The heat-insulating cloth 3, the support frame 2, and the connecting frame 1 together enclose a heat-insulating tunnel. The products inside the microwave oven are always within the heat-insulating tunnel, reducing the space around the products, minimizing heat loss. At the same time, with the reduced space around the products, both the heating efficiency and the heat-insulating performance are enhanced, and the energy consumption of the microwave oven is reduced. The settings of several annular members 22 on the bow-shaped frame 21 and several grooves on the support rod 12 enable the free adjustment of the position of the connecting rod 11 and the coverage range of the heat-insulating cloth 3 when facing products of different quantities and sizes.
