Description

Technical Field

[0001] The invention relates to a cooking machine, in particular to a multi-steaming box cooking machine. Background Art

[0002] At present, the emergence of intelligent cooking equipment has greatly reduced the time and energy of cooking, and therefore has been loved by more and more users. Various cooking devices have appeared on the market today, especially fully intelligent cooking devices, such as electric steamers, microwave ovens, etc.

[0003] The Chinese patent authorization announcement date is August 1, 2017, and the authorization announcement number is CN105395042B, which discloses a "multifunctional intelligent cooking machine". The cooking machine has microwave heating, steam heating, baking heating, and refrigeration functions. Through layout settings, the space utilization rate is improved to meet the user's various needs for food. The cooking machine includes a first steamer, a second steamer and a steam generator, wherein the steam generator is used to control the operation of the two steamers. However, the control of the two steamers by the steam generator is achieved by a separate high-temperature resistant solenoid valve. This implementation scheme has the following disadvantages: 1. The solenoid valve is expensive, which is not conducive to the industrialization of the product; 2. One steam generator corresponds to multiple cavities. When multiple cavities work at the same time, there will be uneven steam in multiple cavities; 3. One generator corresponds to multiple cavities. As long as one of the cavities starts working, the steam generator will start working, which has high requirements for the life of the steam generator; 4. It will inevitably occupy the internal installation space, which is not conducive to the expansion of product functions. Based on the above reasons, the traditional steam generator needs to be improved. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a multi-steamer cooking machine with a simple structure and capable of providing independent heating for different steamers.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a multi-steamer cooking machine, comprising a cooking body, wherein a steam generator and n steamers are arranged in the cooking body, each steamer is provided with a steam inlet hole connected to the steam generator, and the steam generator comprises:

[0006] case;

[0007] n heating chambers, each of which is arranged in the shell, and each of which is numbered from the first heating chamber to the nth heating chamber in sequence. In the order of the numbers, the previous heating chamber is connected to the next heating chamber through an auxiliary channel. The first heating chamber is provided with a liquid inlet, and the nth heating chamber is provided with a liquid outlet. A steam outlet is provided at the top of any heating chamber, and each steam outlet is arranged in a one-to-one correspondence with a steam box, and is connected to the steam inlet hole of the corresponding steam box through a pipeline;

[0008] n heating elements, each heating element is arranged in the housing, each heating element is matched with a heating chamber and is used for heating the corresponding heating chamber;

[0009] n is greater than or equal to 2.

[0010] The beneficial effects of the present invention are as follows: a plurality of steam boxes are arranged in the cooking machine body, and a corresponding number of heating chambers are arranged in the steam generator, and each heating chamber is connected by an auxiliary channel, and water (liquid for evaporation) is added to the first heating chamber through the liquid inlet, and the water enters the second heating chamber through the auxiliary channel, and enters each heating chamber in turn until the nth heating chamber is filled; the first heating chamber is connected to the first steam box, the second heating chamber is connected to the second steam box, and so on, the nth heating chamber is connected to the nth steam box. Take two steam boxes as an example: since each heating chamber is matched with an independent heating element in a one-to-one correspondence, when the water in the first heating chamber is heated, the steam is discharged through the steam outlet at the first heating chamber; at this time, the heating element located in the second heating chamber does not work, although the first heating chamber and the second heating chamber are connected through the auxiliary channel, because the water is in a static state, the water in the first heating chamber will not enter the second heating chamber in large quantities, so the heating element in the first heating chamber will not heat the water in the second heating chamber. In this case, the first heating chamber only heats the first steam box, and the second steam box connected to the second heating chamber is not heated. On the contrary, if the heating element in the first heating chamber does not work and the heating element in the second heating chamber works, the first heating chamber will not heat the first steamer, and the second heating chamber will only heat the second steamer. In this way, it can be achieved that as long as the operation of the heating element in a certain heating chamber is controlled, the steamer corresponding to the heating chamber can be heated, while the steamers corresponding to other non-operating heating chambers are not heated. The present invention can control multiple steamers to work independently at the same time through a steam generator, thereby meeting the needs of different ingredients or audiences, and has a simple structure. Compared with traditional steam generators, it can reduce the connection space, improve space utilization, reduce production costs, and avoid unnecessary cost expenditures. Preferably, a plugging or water outlet valve is installed at the liquid outlet to prevent leakage, and the liquid outlet is only opened when the water in the heating chamber needs to be replaced or the heating chamber needs to be cleaned.

[0011] The bottom of the inner side of the heating chamber is tilted, and the auxiliary channel is located at the lower part of the heating chamber, so the auxiliary channel is connected to the lowest point of the bottom of the previous heating chamber. It helps the water in the previous heating chamber to enter the next heating chamber smoothly, avoiding the residue and accumulation of water due to the height difference, which will affect the quality of the water in the long run and cause the steam to be impure. The bottom of the previous heating chamber is tilted toward the next heating chamber, so as to ensure that the water at the lowest point of the bottom of the previous heating chamber can completely enter the next heating chamber, and so on, to ensure that the connection point between the auxiliary channel and the previous heating chamber is the lowest point of the previous heating chamber. It is further ensured that when the heating chambers connected in series are cleaned, water will not be retained in any heating chamber. Among them, the preferred scheme for the auxiliary channel to be connected to the next heating chamber is to be connected to the highest point of the bottom of the next heating chamber.

[0012] The liquid outlet on the nth heating chamber is located at the lowest point of the bottom of the inner side of the heating chamber, so when cleaning the nth heating chamber, no water will be retained in the heating chamber, ensuring that all liquids can be completely discharged.

[0013] Among them, the heating element is a heating rod, which passes through the surface of the shell and extends to the inside of the corresponding heating chamber. In addition to the heating rod, the heating element can also adopt other heating forms in the prior art. In addition to heating inside the shell, it can also be installed on the outside of the shell for heating, and conduct heat to the water in the heating chamber in the form of heat conduction; in addition, the shell itself can also be directly made into independent heating elements. Since the heating technology is relatively mature, it will not be described one by one here. The only thing to note is that the use of a heating rod has low cost, high controllability and high heating efficiency. For those skilled in the art, the heating part of the heating rod is mainly located inside the shell, and the liquid inside the shell is preferentially heated.

[0014] In order to further improve the heating efficiency, a plurality of heat conducting plates are provided on the outer surface of the heating rod or the inner surface of the heating chamber, and the heat conducting plates are located inside the heating chamber.

[0015] In order to avoid heat transfer between two adjacent heating chambers and increase heating loss, an insulation layer can be set between two adjacent heating chambers. The insulation layer can be made of any insulation material, traditional insulation materials such as glass fiber, asbestos, rock wool, silicate, etc., new insulation materials such as aerogel felt, vacuum board, etc.

[0016] The liquid inlet of the steam generator is equipped with a water inlet valve, and the liquid outlet is equipped with a water outlet valve. A water storage tank is also provided in the cooking machine body, and the water storage tank is connected to the liquid inlet of the steam generator through a water inlet pipe. In order to facilitate the intelligent control of the liquid inlet and liquid outlet of the steam generator, corresponding control valves are provided at the liquid inlet and liquid outlet.

[0017] An exhaust hole is provided at the top of the steam box, and an exhaust channel connected to the external environment is provided at the exhaust hole. A baffle is hinged in the exhaust channel, and the baffle is hinged to the upper part of the inner surface of the exhaust channel, and the shape of the baffle is consistent with the cross-sectional shape of the exhaust channel; an exhaust fan is also installed between the exhaust hole and the baffle. When too much steam accumulates in the steam box, it needs to be exhausted by the exhaust fan, and the baffle is suspended inside the exhaust channel, and the upper part of the baffle is hinged to the upper part of the inner surface of the exhaust channel. Therefore, when the exhaust fan is not in working state, the baffle will not open, thereby preventing steam from leaking out; only when the exhaust fan is working, the wind force generated by the exhaust fan will push the baffle open, so that the exhaust channel is opened, and the excess steam is discharged to the external environment through the exhaust channel.

[0018] A functional cavity is provided in the cooking machine body, and the multi-steamer cooking machine also includes a partition for dividing the functional cavity into individual steamers. The partition can be detachably installed in the functional cavity, and the partition is sealed with the inner wall of the functional cavity. Each steamer is an independent box body, and each independent box body is provided with at least one steam inlet hole. The functional cavity can be spatially divided by installing or removing the partition. The partition can be installed or removed according to the volume of the food to be cooked to ensure that cooking ingredients of different sizes can be loaded into the steamer. Here, there are multiple structures for the detachable installation of the partition and the functional cavity. For those skilled in the art, as long as the partition is relatively fixed in the functional cavity to ensure the spatial stability of the corresponding steam chamber after division, it will be sufficient.

[0019] The partition includes a partition body, and the edge of the partition body is covered with a sealing strip. The functional cavity is divided into a number of independent steam chambers by the partition, and the sealing strip is against the inner wall of the functional cavity, so as to achieve relative isolation on both sides of the partition, that is, the partition achieves isolation between adjacent steam chambers through the sealing strip. Among them, the partition is placed horizontally in the functional cavity, and a convex edge for mounting the partition is convexly provided on the inner wall of the steam box; and a limiting edge is convexly provided above the convex edge, and the distance between the limiting edge and the convex edge matches the thickness of the partition. In terms of the detachable angle, the structure is simple and the operation is convenient; through the cooperation of the convex edge and the limiting edge, the partition can be better fixed to prevent shaking. In addition to the aforementioned convex edge and limiting edge, the detachable method between the partition and the functional cavity can also be provided with a card slot for clamping the edge of the partition on the inner wall of the functional cavity, and the partition is fixed by the card slot.

[0020] The multi-steamer cooking machine also includes a microwave unit for heating the steamers with microwaves. There may be a plurality of microwave units, the number of which is less than or equal to the number of steamers, so as to selectively heat the steamers with microwaves; the microwave units may also be integrated into one module to simultaneously heat multiple or all steamers with microwaves. As for the selection and installation position of the microwave unit, it is common knowledge for those skilled in the art, and specific reference may be made to the composition and installation of a microwave oven.

[0025] The present invention will be further described below in conjunction with the accompanying drawings:

[0026] like Figure 1 , 2 As shown in Figures 3 and 4, this embodiment includes a cooking machine body 1, in which a steam generator 3 and two steam boxes 2 are arranged. A steam inlet 21 connected to the steam generator 3 is opened on the side of each steam box 2, and the two steam boxes 2 are stacked up and down. The steam generator 3 includes a shell 31, and a heating chamber 32 and a heating element 33 installed in the shell 31. There are two heating chambers 32, namely a first heating chamber 321 and a second heating chamber 322. The first heating chamber 321 and the second heating chamber 322 are connected through an auxiliary channel 34. The first heating chamber 321 is also provided with a liquid inlet 311, and the second heating chamber 322 is provided with a liquid outlet 312. A steam outlet 313 is opened on the upper part of any heating chamber 32, and each steam outlet 313 is arranged in a one-to-one correspondence with the steam box 2 and is connected to the steam inlet 21 of the corresponding steam box 2 through a pipeline. There are two heating elements 33, and each heating element 33 is matched with a heating chamber 32 and is used to heat the corresponding heating chamber 32. In order to avoid heat transfer between two adjacent heating chambers 32 and increase heating losses, a heat insulation layer 35 is provided between two adjacent heating chambers 32. As shown in the figure, the middle vertical plate used to block the two adjacent heating chambers 32 is the heat insulation layer 35. In addition, the shell 31 is made of heat insulation material as a whole, which not only improves the heating efficiency, but also avoids heat transfer between adjacent heating chambers 32 and reduces losses. A water outlet valve is installed at the liquid outlet 312 to prevent leakage, and the liquid outlet 312 is only opened when the water in the heating chamber 32 needs to be replaced or the heating chamber 32 needs to be cleaned.

[0027] The auxiliary channel 34 is located at the lower part of the heating chamber 32. As shown in the figure, a notch is provided below the middle vertical plate of the two adjacent heating chambers 32, and the notch is the auxiliary channel 34. The bottom of the inner side of the heating chamber 32 is inclined, and the same auxiliary channel 34 is connected to the lowest point of the bottom of the previous heating chamber. The auxiliary channel 34 is connected to the lowest point of the bottom of the previous heating chamber. The preferred solution for the auxiliary channel 34 to communicate with the next heating chamber is to communicate with the highest point of the bottom of the next heating chamber 32. The heating element 33 is a heating rod, which passes through the surface of the shell 31 and extends to the inside of the corresponding heating chamber 32.

[0028] The surface of the heating rod is provided with a plurality of heat conducting sheets 331, and the heat conducting sheets 331 are located inside the heating chamber 32. A water inlet valve is installed at the liquid inlet 311 of the steam generator 3, and a water storage tank is also provided inside the cooking machine body 1, and the water storage tank is connected to the liquid inlet 311 of the steam generator 3 through a water inlet pipe. An exhaust hole is opened at the upper part of the stacked steam box 2, and an exhaust channel connected to the external environment is provided at the exhaust hole, and a baffle is hinged in the exhaust channel, and the baffle is hinged to the upper part of the inner surface of the exhaust channel, and the shape of the baffle is consistent with the cross-sectional shape of the exhaust channel; an exhaust fan is also installed between the exhaust hole and the baffle. When too much steam accumulates in the steam box 2, it needs to be exhausted through the exhaust fan, and the baffle is suspended inside the exhaust channel, and the upper part of the baffle is hinged to the upper part of the inner surface of the exhaust channel. Therefore, when the exhaust fan is in a non-working state, the baffle will not open, thereby preventing steam from leaking out; only when the exhaust fan is working, the wind force generated by the exhaust fan will push the baffle open, so that the exhaust channel is opened, and the excess steam is discharged into the external environment through the exhaust channel.

[0029] The cooking machine body 1 is provided with a functional cavity 11, which is divided into steam chambers 2 by a partition 4, and the partition 4 is horizontally arranged and detachably installed in the functional cavity 11. The partition 4 includes a partition body 41, and the edge of the partition body 41 is covered with a sealing strip 42. The partition 4 is sealed with the inner wall of the functional cavity 11 through the sealing strip 42, thereby avoiding steam leakage and ensuring the independent operation of each steam chamber 2. Among them, a convex edge 23 for the partition 4 to be erected is convexly provided on the inner wall of the steam box 2; and a limiting edge 24 is convexly provided above the convex edge 23, and the distance between the limiting edge 24 and the convex edge 23 matches the thickness of the partition 4.

[0030] A microwave unit (not shown) is installed outside each steam chamber 2. Each microwave unit includes a transformer, a capacitor, and a magnetron. For those skilled in the art, the microwave unit belongs to a mature prior art, and can be referred to as a microwave oven and other equipment, and will not be described in detail here. The number of microwave units can be less than or equal to the number of steam boxes 2, so that microwave heating can be selectively performed on the steam boxes 2.

[0031] In the present invention, a plurality of steam boxes 2 are arranged in the cooking machine body 1, and a corresponding number of heating chambers 32 are arranged in the steam generator 3, wherein the number of steam boxes 2 is not limited to 2, and can be infinitely expanded as needed. Since each heating chamber 32 is matched with an independent heating element 33 in a one-to-one correspondence, when the water in the first heating chamber 32 is heated, the steam is discharged through the steam outlet 313 at the first heating chamber 321; at this time, the heating element located in the second heating chamber 322 does not work, although the first heating chamber 321 and the second heating chamber 322 are connected through the auxiliary channel 34, because it is static water, the water in the first heating chamber 321 will not enter the second heating chamber 322 in large quantities, so the heating element 33 in the first heating chamber 321 will not heat the water in the second heating chamber 322. In this case, the first heating chamber 321 only heats the first steam box, and the second steam box connected to the second heating chamber 322 is not heated. On the contrary, if the heating element 33 in the first heating chamber 321 does not work, and the heating element 33 in the second heating chamber 322 works, the first heating chamber 321 will not heat the first steamer, and the second heating chamber 322 will only heat the second steamer. In this way, it can be achieved that as long as the operation of the heating element 33 in a certain heating chamber 32 is controlled, the steamer 2 corresponding to the heating chamber 32 can be heated, while the steamers 2 corresponding to other non-operating heating chambers 32 are not heated. The present invention can control multiple steamers 2 to work independently at the same time through a steam generator 3, thereby meeting the needs of different ingredients or audiences, and has a simple structure. Compared with traditional steam generators, it can reduce the connection space, improve space utilization, reduce production costs, and avoid unnecessary cost expenditures.
