Steam cooking device with weighing function

Abstract

This invention discloses a steam cooking device with a weighing function, comprising a shell, a weighing component, a transfer component, a load-bearing component, and a tray. The weighing component is located inside the shell at the top and at the air inlet of the steam cooking device's fan. The tray is snapped onto the load-bearing component, which is connected to the weighing component via the transfer component. This invention weighs the food by placing it on the tray and snapping it onto the load-bearing component. The load-bearing component then transfers the weight of the food to the weighing component via the transfer component. Furthermore, by placing the weighing component at the air inlet of the steam cooking device's fan, the negative pressure of the fan cools the surrounding air, keeping it within its normal operating temperature range. Additionally, the transfer component extends the distance heat travels from the heating element of the steam cooking device to the weighing component, reducing heat transfer efficiency and avoiding the use of low thermal conductivity materials, thereby reducing costs.

Description

Technical Field

[0001] The invention belongs to the technical field of steam cooking devices, and in particular relates to a steam cooking device with a weighing function. Background Art

[0002] When baking food, users cannot judge the baking time well, which leads to poor taste of the food, which is the main defect of using ovens. To address this defect, weighing sensors can be used to weigh the weight of the ingredients, and then the cooking time can be determined in combination with the smart menu. Even novice cooks can quickly cook healthy and delicious dishes.

[0003] However, currently, steam cooking devices can only achieve weighing at a single cooking layer (for example, weighing sensors are respectively arranged on both sides of the cavity) or at a single dedicated position (for example, a load-bearing column is arranged at the bottom of the inner cavity to cooperate with a tray to achieve food weighing), and the above weighing structure usually uses at least two or more weighing sensors in combination to achieve the effect of balanced weighing. As the number of weighing sensors increases, it is inevitable that the cost will increase and the reliability of components will be improved. In addition, since the working environment temperature requirement of the weighing sensor is generally within the range of 90°C, low thermal conductivity materials are currently mainly used to reduce the temperature transfer of high temperature flue gas to the weighing sensor, thereby increasing the material cost of the weighing function. Summary of the invention

[0004] The purpose of the present invention is to provide a steam cooking device with a weighing function, which solves the problem of high cost of the existing weighing steam cooking devices.

[0005] The technical solution adopted by the present invention is a steam cooking device with a weighing function, which includes a shell, a weighing component, a transmission component, a load-bearing component and a tray. The weighing component is arranged at the top of the shell and located at the air inlet of the fan of the steam cooking device. The tray is clamped on the load-bearing component. The load-bearing component is connected to the weighing component through the transmission component and the weight of the object on the load-bearing component is transferred to the weighing component through the transmission component.

[0006] The present invention is also characterized in that:

[0007] The transfer assembly includes four groups of transfer units and a support frame. The four groups of transfer units are arranged in pairs on two opposite sides of the steam cooking device. The support frame is arranged on the top inner side of the steam cooking device and connected to the transfer units.

[0008] The transfer unit includes at least one connecting rod, a guide column and a buffer pad. The guide column is arranged outside the shell and corresponds to the load-bearing component arranged inside the shell. The buffer pad is arranged inside the guide column and passes through the side of the shell.

[0009] When more than two connecting rods are provided, adjacent connecting rods are connected by a transition rod.

[0010] The support frame includes two parallel U-shaped support rods, a fixed rod and a supporting rod. The vertical sides of the two U-shaped support rods are respectively connected to four groups of transmission units. The fixed rod is arranged between the horizontal rods of the two U-shaped support rods, and the supporting rod is arranged in the middle between the horizontal rods of the two U-shaped support rods for supporting the weighing assembly.

[0011] Two load-bearing components are provided, which are respectively located on two opposite sides of the steam cooking device, and each of them comprises a U-shaped bracket, and two parallel edges of the U-shaped bracket are connected by passing through the guide column and the connecting rod in the horizontal direction.

[0012] The load-bearing component further includes a first vertical rod, a second vertical rod and a plurality of parallel cross rods arranged between the first vertical rod and the second vertical rod. The upper ends of the first vertical rod and the second vertical rod both extend outward, and the lower ends of the first vertical rod and the second vertical rod are fixed at the corners of the U-shaped bracket.

[0013] It further comprises an auxiliary weighing assembly, which is arranged on the shell and is used to improve the measurement accuracy of the weighing assembly.

[0014] The auxiliary weighing component comprises a middle plate, a guide groove and a limit ring, wherein the guide groove is provided on the middle plate and corresponds to the number of the transmission units, the limit ring is sleeved on the transmission component and located above the middle plate, and the diameter of the limit ring is greater than the inner diameter of the guide groove.

[0015] It further comprises a ceiling bracket, which is arranged at the top of the inner side of the shell and is used to fix the weighing component.

[0016] Compared with the prior art, when the present invention is used, food is placed on a tray, and the tray is clamped on the load-bearing component. The load-bearing component transfers the weight of the food to the weighing component through the transmission component to complete the weighing of the food, and by arranging the weighing component at the air inlet of the fan of the steam cooking device, the negative pressure suction force of the fan in the steam cooking device is used to drive the surrounding air to cool the weighing component, so that it is always within the normal working temperature range; and, by setting the transmission component, the distance of heat from the heating pipe of the steam cooking device to the weighing component is extended, thereby increasing the heat transfer time, effectively reducing the high-temperature heat in the cavity during cooking to be transferred to the weighing component, avoiding the use of low thermal conductivity materials, and thus reducing costs.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The embodiment of the present invention provides a steam cooking device with a weighing function, such as Figure 1 As shown, it comprises a housing 1, a weighing component 2, a transmission component 3, a load-bearing component 4 and a tray 5, wherein the weighing component 2 is arranged at the top of the housing 1 and located at the air inlet of the fan of the steam cooking device, and the tray 5 is clamped on the load-bearing component 4, and the load-bearing component 4 is connected to the weighing component 2 through the transmission component 3 and the weight of the object on the load-bearing component 4 is transmitted to the weighing component 2 through the transmission component 3;

[0029] The weighing component 2 is a cantilever beam sensor.

[0030] In this way, by adopting the above structure, food is placed on the tray 5, and the tray 5 is clamped on the load-bearing component 4. The load-bearing component 4 transfers the weight of the food to the weighing component 2 through the transmission component 3 to complete the weighing of the food. The weighing component 2 is set at the air inlet of the fan of the steam cooking device, and the negative pressure suction force of the fan in the steam cooking device is used to drive the surrounding air to cool the weighing component, so that the cantilever beam sensor is always placed within the normal operating temperature range. The setting of the transfer component 3 extends the distance of heat from the heating tube of the steam cooking device to the weighing component 2, thereby increasing the heat transfer time, effectively reducing the high-temperature heat in the cavity during cooking to be transferred to the weighing component 2, avoiding the use of low thermal conductivity materials, and thus reducing costs.

[0031] like Figure 2-7 As shown, the transmission assembly 3 includes four groups of transmission units 31 and a support frame 32. The four groups of transmission units 31 are respectively arranged on two opposite sides of the steam cooking device, and the support frame 32 is arranged on the top of the inner side of the steam cooking device and connected to the transmission units 31.

[0032] The transmission unit 31 includes at least one connecting rod 311, a guide column 312 and a buffer pad 313. The guide column 312 is arranged outside the housing 1 and corresponds to the load-bearing component 4 arranged inside the housing 1. The buffer pad 313 is arranged inside the guide column 312 and passes through the side of the housing 1. When more than two connecting rods 311 are provided, adjacent connecting rods 311 are connected by a transition rod 314;

[0033] The support frame 32 includes two parallel U-shaped support rods 321, a fixing rod 322 and a supporting rod 323. The vertical sides of the two U-shaped support rods 321 are respectively connected to the four groups of transmission units 31. The fixing rod 322 is arranged between the horizontal rods of the two U-shaped support rods 321. The supporting rod 323 is arranged in the middle between the horizontal rods of the two U-shaped support rods 321 to support the weighing assembly 2.

[0034] In this way, by arranging an external buffer pad 313 in the side guide column 312, the cumulative assembly error of the support frame 32, the load-bearing component 4 and the steam cooking device cavity can be effectively reduced, and the external buffer pad 313 can be installed and removed from the inside of the cavity, which is convenient for installation and after-sales maintenance; in addition, the buffer pad 313 blocks the cavity from the outside, effectively preventing the loss of heat in the cavity during cooking; by utilizing the deformation and compression of the cavity of the buffer pad 313, the load-bearing component 4 remains in a stable state after installation and bearing food, thereby improving the stability of the weighing zeroing and the weighing state.

[0035] like Figure 8As shown, two load-bearing components 4 are provided, which are respectively located on two opposite sides of the steam cooking device, and each of them includes a U-shaped bracket 41. Two parallel edges of the U-shaped bracket 41 are connected by passing through the guide column 312 and the connecting rod 311 in the horizontal direction;

[0036] In this way, when only one connecting rod 311 is provided, it is connected to two parallel sides of the U-shaped bracket 41, thereby achieving heating of a single layer of food in the steam cooking device.

[0037] The load-bearing assembly 4 further includes a first vertical rod 42, a second vertical rod 43, and a plurality of mutually parallel cross rods 44 disposed between the first vertical rod 42 and the second vertical rod 43. The upper ends of the first vertical rod 42 and the second vertical rod 43 both extend outwardly to form an extension end 45. The lower ends of the first vertical rod 42 and the second vertical rod 43 are fixed at the corners of the U-shaped bracket 41.

[0038] Thus, when two connecting rods 311 are provided, the extension end 45 passes through the guide column 312 and is connected to the transmission assembly 3, and by providing different numbers of cross rods 44 between the first vertical rod 42 and the second vertical rod 43, the steam cooking device can heat multiple layers of food;

[0039] In this way, four transfer units 31 correspond to two load-bearing components 4, ensuring the accuracy of weight transfer.

[0040] It further comprises an auxiliary weighing assembly 6, which is arranged on the housing 1 to improve the measurement accuracy of the weighing assembly 2; the auxiliary weighing assembly 6 comprises a middle plate 61, a guide groove 62 and a limit ring 63, wherein the guide groove 62 is provided on the middle plate 61 and corresponds to the number of the transmission units 31, the limit ring 63 is sleeved on the transmission assembly 3 and is located above the middle plate 61, and the diameter of the limit ring 64 is greater than the inner diameter of the guide groove 63;

[0041] In this way, by providing a limit ring 64 on the transmission component 3, damage to the weighing sensor caused by excessive weight of food can be avoided;

[0042] like Figure 9-10 As shown, it further includes a ceiling bracket 7, which is arranged at the top of the inner side of the housing 1 for fixing the weighing assembly 2; in this way, the ceiling bracket 7 is used to realize the top installation of the cantilever beam type sensor, which effectively reduces the number of sensors used, and only needs to install and disassemble the top plate of the housing 1 to realize the installation, debugging, maintenance and replacement of the sensor;

[0043] In addition, it further includes a mounting plate 8, wherein the mounting plate 8 is located between the weighing assembly 2 and the transmission assembly 3 and is used to provide a supporting force for the weighing assembly 2;

[0044] In addition, the mounting plate 8 is located on the supporting rod 323, that is, the load-bearing center of the support frame 32, wherein the vertical edge of the U-shaped support rod 321 passes through the middle plate 61 and the guide groove 62 on the middle plate, so that the auxiliary weighing component 6 is within the vertical guide positioning range, avoiding the generation of component force due to the tilted installation of the auxiliary weighing component 6, resulting in a deviation between the detected food weight and the actual food weight.

[0045] The top and left and right sides of the ceiling bracket 7 and the top plate of the housing 1 are fixed by welding; a pressing shape 71 is provided in the middle of the ceiling bracket 7 to improve the rigidity of the ceiling bracket 7 .

[0046] The upper surface of the cantilever beam sensor is connected to the ceiling bracket 7 by screws, and the lower surface is arranged on the mounting plate 61 and connected by screws.

[0047] Working process:

[0048] The food is placed on the tray 5, wherein a single or multiple trays 5 are clamped between the cross bars 43 of the two load-bearing components 4 to form a single or multiple weighing layers. The tray 5 then passes through the transfer unit 31, the support frame 32, and the mounting plate 8 in sequence to transfer the weight, and finally transfers the weight to the cantilever beam weighing sensor, thereby achieving the weighing of the food.

[0049] The steam cooking device may be a steam box, a steam oven, a steam-bake all-in-one device, a steam-bake micro-machine, etc.

[0050] When the present invention is used, food is placed on a tray, and the tray is clamped on the load-bearing component. The load-bearing component transfers the weight of the food to the weighing component through the transmission component to complete the weighing of the food. In addition, by arranging the weighing component at the air inlet of the fan of the steam cooking device, the negative pressure suction force of the fan in the steam cooking device is used to drive the surrounding air to cool the weighing component, so that it is always within the normal working temperature range. In addition, the setting of the transmission component prolongs the distance of heat from the heating tube of the steam cooking device to the weighing component, thereby increasing the heat transfer time, effectively reducing the high-temperature heat in the cavity during cooking to be transferred to the weighing component, avoiding the use of low thermal conductivity materials, and thus reducing costs.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
