Description

Technical Field

[0001] This invention belongs to the field of rice cooking technology, and particularly relates to a rice dry steaming device. Background Technology

[0002] The cooking of rice relies on a set of rice cooking equipment. Depending on the amount of rice to be cooked, there are commercial rice cooking equipment and household rice cooking equipment. Household rice cooking equipment, such as electric rice cookers, is suitable for cooking small amounts of rice.

[0003] Commercial rice steamers have a large capacity, so their structure differs significantly from that of household rice cookers. These large-capacity steamers primarily rely on steam for cooking.

[0004] For example, Chinese patent application number CN202422765827.3 discloses an energy-saving rice steamer with internal steam circulation. The technical solution disclosed in this patent achieves energy saving through internal steam circulation. Its main structure includes a steamer cabinet, a steaming chamber inside the cabinet, a water tank below the steaming chamber, an electric heater installed in the water tank, and the upper end of the water tank communicating with the steaming chamber. Several steaming trays are installed in the steaming chamber, with each tray resting on a tray support on both sides. One end of each tray is near the cabinet door, and the other end forms a steam flow channel with the inner wall of the steaming chamber. Several guide plates are inserted into the steam flow channel, with the upper end of the guide plates angled upwards near the corresponding steaming tray, and the lower end of the guide plates located in the steam flow channel. This structure enables steam circulation and heat exchange during the rice steaming process, thereby improving the thermal efficiency of the rice steamer and reducing waste heat loss.

[0005] However, in actual operation, this type of rice steaming device, which has a large capacity, requires a very large amount of steam. As a result, the rice is often already cooked in the later stages of steaming, but a large amount of redundant steam remains. This redundant steam cannot be recovered and reused, which not only leads to excessive energy consumption in rice steaming, but also causes the rice to cool down for too long after steaming. Furthermore, the large amount of redundant steam produces a large amount of condensate after cooling, which will then flow back into the rice along the rice hopper wall. This causes the cooked rice to become soggy and lose its physical properties after steaming, such as becoming soft and mushy, which seriously affects the taste of the rice.

[0006] Therefore, by using an energy-saving, environmentally friendly, and highly intelligent rice steaming device, energy consumption can be reduced during use, and redundant steam can be recycled after steaming, reducing the amount of condensate from the steam entering the rice and affecting its taste, which can produce very significant economic benefits.

A water level sensor is installed on the lower side wall of the water tank.

[0014] Preferably, the side walls on both sides of the compartment cover are respectively hinged to the side wall of the main unit box via a telescopic hinge structure; The telescopic hinge structure includes a telescopic rod, which includes a sleeve rod and a telescopic adjustment rod slidably installed in the sleeve rod. A hinge cap is fixedly connected to the telescopic adjustment rod and the sleeve rod respectively.

[0015] Preferably, the hinged flip end of the compartment cover is hinged to the main unit housing via a pair of hinges, and the open end of the compartment cover is locked by a pair of locking tongues; The locking tongue includes a handle, a locking shaft that is rotatably connected to the top of the compartment cover, and a locking tongue that is fixedly connected to the locking shaft.

[0019] The present invention has the following beneficial effects: 1. This invention improves a steam system by recovering and reusing a large amount of redundant steam in the rice cooking chamber as a heating source for the clean water tank. The water in the clean water tank is heated by the recovered steam, thus reducing energy consumption during the rice cooking process. The clean water tank pumps hot water into the rice cooking chamber, achieving energy savings. Simultaneously, after the rice is cooked, redundant steam in the rice cooking chamber is quickly recovered and reused, preventing a large amount of steam from remaining inside.

[0020] The excess steam generated during the later stages of rice cooking is then channeled through a steam trough and steam return pipe into the clean water tank to heat the water there. This method achieves the recovery and utilization of thermal energy by sending a large amount of excess steam from the rice cooking trough into the clean water tank to heat the water during the later stages of rice cooking. 2. A steam silencing structure is used to reduce noise during the steam heating process of rice. Specifically, this structure includes a steam silencing pipe with several steam silencing holes (from which steam is discharged), and the pipe connects to a steam tank. By diverting steam through each silencing hole, excessive steam noise is avoided.

Intelligent control: Real-time monitoring and control of water level and temperature in the clean water tank, water tank, and rice bin are achieved through level sensors, temperature sensors, and electromagnetic control valves, realizing automated control of water intake and drainage, which greatly improves the intelligence level of the entire device.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

If the specific posture changes, the directional indication will also change accordingly.

[0028] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0029] Example 1 like Figure 1-9 As shown, a rice dry steaming device includes a rice bin 1 and a water and steam system 4 for supplying water and steam to the rice bin 1. The water and steam system 4 includes a water tank 41, a steam generator 42, a clean water tank 43, a steam system 44 for supplying steam, and a water supply system 45 for supplying water.

[0030] The rice hopper 1 is made of stainless steel and welded into a rectangular structure. During the rice cooking process, the pre-washed rice is placed into a rice mesh bag (such as a non-woven fabric rice mesh bag) according to the existing rice cooking method. The rice mesh bag is then placed into the rice hopper 1, and the hopper lid is closed. The rice is then heated by the steam system 44.

[0031] This invention addresses the problem of existing rice steaming devices that cannot recover steam from the rice container 1. As a result, a large amount of redundant steam cannot be recovered and reused after the rice is cooked, leading to excessive energy consumption and energy waste. In addition, a large amount of steam is prone to cooling and liquefaction, which can easily flow into the rice along the container wall, affecting the taste of the rice.

[0032] Based on this, the present invention improves a steam system 44 to recover and reuse a large amount of redundant steam in the rice hopper 1 as a heating source for the clean water tank 43. This allows the water in the clean water tank 43 to be heated by the recovered steam, thus reducing the energy consumption of the clean water tank 43 in heating water during the rice cooking process. The clean water tank 43 also pumps hot water into the rice hopper 1, achieving energy savings in this way. Simultaneously, after the rice is cooked, the redundant steam in the rice hopper 1 is quickly recovered and reused, preventing a large amount of steam from remaining in the rice hopper 1.

[0033] Specifically, the steam system 44 includes a steam supply pipeline structure and a steam recovery pipeline structure for pumping recovered steam into the clean water tank 43.

[0034] It also includes a steam tank 444 (stainless steel square tube structure) that is fixedly installed at the bottom of the rice bin 1, and the steam tank 444 pumps steam into the rice bin 1.

[0035] Meanwhile, when high-temperature and high-pressure steam enters the rice hopper 1 through the steam tank 444, the high-temperature and high-pressure steam will generate a lot of steam noise. Therefore, in order to realize the pumping of steam from the steam tank 444 into the rice hopper 1, while avoiding the generation of "steam noise" by the steam in the rice hopper 1, the present invention is further improved as follows: The above also includes a steam silencing structure installed in the rice silo 1; the steam silencing structure includes a steam silencing pipe 445 (a stainless steel pipe that spans across the two side walls of the rice silo 1; specifically, in the same way as the existing installation method, the two ends of the steam silencing pipe 445 are respectively fixedly connected to the mounting pipe seat, and the mounting pipe seat is fixedly installed on the wall of the rice silo 1), and the steam silencing pipe 445 is provided with several steam silencing holes 4451 (steam is discharged from the steam silencing holes 4451), and the steam pipe is connected to the steam tank 444.

[0036] By diverting steam from each steam silencer hole 4451, the generation of large steam noise is avoided.

[0037] The aforementioned steam supply pipeline structure includes a main steam supply pipeline 442 connected to the steam generator 42, which in turn connects to the steam tank 444 (the main steam supply pipeline 442 pumps steam into the rice hopper 1 to heat the rice). The steam generator 42 is a conventional steam generating device disclosed in the prior art, its main structure including a stainless steel shell and a heating resistance rod installed inside the shell, which heats water to generate high-temperature, high-pressure steam.

[0038] It also includes a branch steam pipe 443 connected to the main steam supply pipe 442, and the branch steam pipe 443 is connected to the clean water tank 43 (the branch steam pipe 443 is used to pump part of the steam into the clean water tank 43 to heat the clean water); the steam recovery pipe structure includes a steam return pipe 441 connected to the steam tank 444, and the steam return pipe 441 is connected to the clean water tank 43.

[0039] Meanwhile, the redundant steam generated in the later stage of heating the rice silo 1 enters the clean water tank 43 through the steam tank 444 and the steam return pipe 441 to heat the clean water in the clean water tank 43.

[0040] In this way, during the later stages of rice steaming, a large amount of redundant steam in the rice hopper 1 is sent into the clean water tank 43 to heat the clean water in the clean water tank 43, thereby realizing the recovery and utilization of heat energy.

[0041] Example 2 like Figure 1-9 As shown, in this embodiment, based on the structure of embodiment 1, in order to improve the convenience of using the entire device, the main unit box 2, water tank 41, steam generator 42, clean water tank 43, steam system 44 and water supply system 45 are integrated and installed in the main unit box 2.

[0042] Specifically, the top of the rice hopper 1 is hinged with a hopper cover 3; the bottom is fixedly connected to a main unit box 2, and the water tank 41, steam generator 42, clean water tank 43, steam system 44 and water supply system 45 are integrated and installed inside the main unit box 2.

[0043] Similar to existing chassis structures, the main chassis 2 includes an aluminum alloy chassis frame (formed by welding multiple aluminum alloy square pieces, serving as a supporting frame structure; the main structure includes an upper bracket supporting the upper frame structure of the rice bin 1, with several support frames welded to the upper bracket as supporting structures, and a bottom plate welded to the bottom of the support frames) and an aluminum alloy panel fixedly mounted on the chassis frame, as well as a bottom plate fixedly welded to the bottom of the chassis frame.

[0044] The aforementioned clean water tank 43 and steam generator 42 are both fixedly installed on the base plate. They also have the same structure as the existing cabinet with an openable and closable door, and include a pair of hinged doors for opening and closing the main unit 2.

[0045] The water tank 41 is fixedly installed on the inner wall of the aluminum alloy panel by the hanging plates welded to the top and bottom.

[0046] The above structure integrates all working components into the main unit housing 2, thereby making the device easy to use.

[0047] Example 3 like Figure 1-9 As shown, in this embodiment, based on the structure of embodiment 2, the rice is cooked by heating with steam. During the cooking process, a certain amount of water needs to be added to the rice container 1. Therefore, the water supply system 45 includes a main water supply pipe 451 (the water inlet is located on the outside of the side wall of the main unit 2). The main water supply pipe 451 is connected to the water tank 41 through a T-connector. That is, the main water supply pipe 451 is connected to an external water supply pipe, such as a tap water pipe, to supply water to the entire device.

[0048] The outlet of the main water supply pipe is connected to the clean water tank 43 (connected to the upper side wall of the clean water tank 43). Water is supplied to the water tank 41 and the clean water tank 43 through the main water supply pipe.

[0049] Meanwhile, the water supply system 45 also includes a water supply pipe 452 connected to the lower end of the clean water tank 43. In the existing method, a water supply pump 4521 is installed on the water supply pipe 452. During operation, the water in the clean water tank 43 is pumped to the rice bin 1 by the water supply pump 4521.

[0050] The aforementioned water supply system 45 also includes a connecting pipe structure that connects the water tank 41 and the steam generator 42; the connecting pipe structure includes a U-shaped connecting pipe 412 that connects to the top and bottom of the water tank 41 respectively, and the U-shaped connecting pipe 412 connects to the steam generator 42.

[0051] That is, the water in the water tank 41 is pumped into the steam generator 42 through the U-shaped connecting pipe (the water tank 41 is specifically for supplying water for steam generation).

[0052] During operation, water is supplied to the clean water tank 43, water tank 41, steam generator 42, and rice hopper 1 through the above-mentioned pipeline system.

[0053] Meanwhile, according to the existing method, a rice storage drain pipe 11 is installed at the bottom of the rice storage 1; the rice storage drain pipe 11 is used to drain excess water from the rice storage. Similarly, a residual water drain pipe 421 is installed on the steam generator 42, and the residual water in the steam generator 42 is discharged from the residual water drain pipe 421.

[0054] Example 5 like Figure 1-9 As shown, in this embodiment, based on the structure of embodiment 4, in order to accurately monitor and control the water volume in the rice storage bin 1, the clean water tank 43, and the water tank 41, a liquid level sensor 33 and a temperature sensor 34 are installed at the lower end of the wall of the rice storage bin 1. The liquid level sensor 34 monitors the water level in the rice storage bin 1, and the temperature sensor 34 monitors the temperature.

[0055] Similarly, the upper and lower ends of the side wall of the clean water tank 43 are respectively equipped with an upper liquid level sensor and a lower liquid level sensor 4431; the lower end of the side wall of the water tank 41 is equipped with a water tank liquid level sensor 411.

[0056] Meanwhile, in accordance with the existing method, the steam system 44 and the water supply system 45 are respectively equipped with several electromagnetic valves A for controlling the inlet and outlet of steam and the inlet and outlet of water.

[0057] Specifically, an electromagnetic valve A is installed on the water supply pipe 452 to control the water inlet, such as the main water supply pipe 452 and the water supply pipe 452 to control the water entering the clean water tank 43 and the rice bin 1. An electromagnetic valve A is installed on the rice bin drain pipe 11 and the residual water drain pipe 421 to control the drainage.

[0058] Similarly, solenoid valves A can be installed on the main steam supply pipeline 442, branch steam pipeline 443, and recovery steam pipeline 441 to control the steam inlet and outlet.

[0059] According to existing intelligent control methods, the aforementioned liquid level sensor, solenoid valve, and water supply pump 4521 are all controlled by existing control systems (such as PLC control). For example, the PLC control circuit controls the opening and closing of the solenoid valve and the operation and shutdown of the water supply pump 4521. Similar to existing methods, the PLC control circuit is installed in the electrical box, which is fixedly installed in the main unit housing 2.

[0060] Example 6 like Figure 1-10 As shown, in this embodiment, based on the structure of embodiment 4, the side walls on the left and right sides of the above-mentioned compartment cover 3 are respectively hinged to the side walls of the main unit box 2 through the telescopic hinge structure 32.

[0061] The telescopic hinge structure 32 makes it easier to open the lid. Specifically, the telescopic hinge structure 32 includes a telescopic rod, which is the same as the existing telescopic rod structure. The telescopic rod includes a sleeve rod 321 and a telescopic adjustment rod 322 that is slidably installed in the sleeve rod 321. A hinge cap 323 is fixedly connected to the telescopic adjustment rod 322 and the sleeve rod 321 respectively. A mounting base 324 is fixedly connected to the side wall of the lid 3 and the main unit box 2 respectively. A pin that is hinged to the hinge cap 323 is fixedly connected to the mounting base 324.

[0062] Similar to the existing hinged compartment cover 3, the front side wall of the compartment cover 3 is hinged to the main unit housing 2 via a pair of hinges. The open end (rear side) of the compartment cover 3 is locked by a pair of locking tongues 31.

[0063] When the compartment cover 3 is closed, the compartment cover 3 is closed by the locking tongue 31, and vice versa. Specifically, the locking tongue 31 is the same as the existing locking tongue structure. The locking tongue 31 includes a handle 311, a locking shaft that is rotatably connected to the top of the compartment cover 3 is fixedly connected to the handle 311, and a locking tongue 312 is fixedly connected to the locking shaft.

[0064] Correspondingly, it also includes a non-circular locking arm 313 (the lower end of which is fixedly installed on the side wall of the main unit 2 by bolts) that is fixedly connected to the side wall of the main unit 2 and cooperates with the locking tongue 312; turn the handle 311 until the locking tongue 312 engages with the locking end of the non-circular locking arm 313 (the locking end has an L-shaped structure, and the locking tongue 312 engages with the locking end (the locking end maintains a certain distance from the compartment cover, so as not to affect the opening of the compartment cover), and the stop is limited at the bottom of the locking end) to lock the compartment cover 3. Conversely, turn the handle 311 to drive the locking tongue 312 to disengage from the locking end and open the compartment cover 3.

[0065] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above.
