Description

Technical Field

[0001] The utility model relates to the technical field of kitchen cooking equipment, in particular to a heating module of a split modular steam box. Background Art

[0002] The rice steamer is a kitchen appliance, mainly used for steaming rice. When steaming rice, the raw rice is placed in the rice steamer, and then the raw rice is heated by the heating device in the rice steamer. The steamer involved in this application is used in special underwater environments, such as cooking equipment on ships and submarines. Since the submarine cabins are independent, each independent cabin has a watertight door, which is very small, generally with a diameter of only 750mm (often called a manhole by the staff). At present, the traditional steamer is generally an integrated box structure, which occupies a large area and is not easy to be installed in the cabin as a whole. However, with the change of demand or heating source, only the main body of the rice steamer can be replaced, and the requirement of switching and repeating under multiple heat sources cannot be realized.

[0003] For example, the patent announcement number is CN105581634B, and the patent name is: an existing patent technology for a gas rice steaming box, which specifically discloses "a gas rice steaming box, a mounting frame is provided at the lower end of the box body, a first heat insulation board is provided on the mounting frame, a heater and an ignition device are fixed on the mounting frame, and a controller and a handle are fixed on the first heat insulation board, a slide rail is provided on the box body, and a slide groove matching the slide rail is provided on the mounting frame. When inspecting the heater, the mounting frame can be easily pulled out of the box body, and the heater inspection is very convenient." The above patent is a rice steaming device that uses a single gas method to heat and generate steam, and the box body is an integrated welded structure, and the heat source cannot be replaced as needed.

[0004] For example, the patent announcement number is CN105559532B, and the patent name is an existing patent technology for a rice steamer. It specifically discloses "a rice steamer, a sealing gasket is arranged between the box body and the box door, and the sealing gasket is bonded to the box body, and a receiving groove for accommodating the sealing gasket is opened on the box door, and a sealing groove is also opened in the receiving groove, and a labyrinth sealing effect is formed between the sealing gasket and the accommodating groove, which greatly optimizes the sealing performance of the rice steamer and saves resources." The improvement point of the above patent is only to improve the ribs in the box body to realize the function of placing the steaming plate in separate plates. It is also impossible to replace the heat source as needed, and the box body is also an integrated welded structure.

[0005] The existing known utility model patents have the following deficiencies:

[0006] 1. It cannot meet the needs of replacing different heat sources.

[0007] 2. The box body cannot be disassembled, and installation, disassembly and transportation are difficult and bulky.

[0008] 3. Welding structure connection is mostly adopted, but the polyurethane foam box is particularly afraid of high-temperature welding. Secondary welding will cause the foam layer of the box to shrink due to heat, resulting in a sharp drop in thermal insulation efficiency. Utility Model Content

[0009] The technical problem to be solved by the utility model is: how to solve the problem that the heat source is not easy to be replaced as needed because most steamers currently adopt an integrated structure.

[0010] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0011] A heating module for a split modular steamer comprises a heating module installed at the bottom of the steamer module, wherein a reserved installation hole is provided at the top of the heating module; the heating module comprises a heating shell arranged at the bottom of the box module, wherein a heating element and a circuit control box are arranged inside the heating shell, and the circuit control box is electrically connected to the heating element.

[0012] The heating module of the present application can be designed independently, is not attached to the steamer body, can be removed from the steamer, and the heating elements inside the heating module can be replaced. Generally, different heat sources can be designed into different styles according to different working conditions, but they can all be connected to the box module and have strong applicability.

[0013] As a further solution of the utility model: the heating element is an electric heating element, a steam heating element, a gas heating element, an electromagnetic heating element, or a heat pump heating element.

[0014] As a further solution of the utility model: the electric heating element includes an electric heater arranged inside the heating shell, an electric heating tube is installed inside the electric heater, a drainage pipe is provided at the bottom of the electric heater, and a water injection pipe is installed on one side of the electric heater.

[0015] As a further solution of the utility model: a solenoid valve and a filter are provided on the water injection pipe.

[0016] As a further solution of the utility model: a steam outlet pipe is provided on the top of the heating shell.

[0017] As a further solution of the utility model: a water receiving trough is installed on the front side of the heating shell, and the water receiving trough is connected with the water injection pipe through a pipeline.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The present application adopts a split design of the control module, the box module and the heating module, which are installed separately and modularly combined, and can be detachably installed in pairs, thereby reducing the skill requirements of the equipment and operators for installation and maintenance, especially the heating module. The heating module can be freely combined with other modules to adapt to different heat sources, and the heating module can be reused. For example, if electric heating is changed to steam heating, only one heating source needs to be changed; at the same time, the present application uses split installation to facilitate transportation, and the disassembled modules can pass through narrow spaces, such as underwater ships;

[0020] Second, the control module, the box module and the heating module of the present application are all installed by bolt fixing, which overcomes the shrinkage of the polyurethane foam box caused by the high temperature of welding;

[0021] 3. The steaming tray rack of the present application is different from the traditional welded steaming tray rack. The steaming tray rack in the box of the present invention is not installed by welding. The steaming tray rack of the present application can be freely disassembled and fixed with bolts, which is convenient for maintenance and replacement, reduces the dependence on welding skills, and is repeatable and interchangeable. At the same time, the ball bearing structure is used to achieve guidance and positioning to prevent the steaming tray from being affected by the shaking of the ship. It is used to guide the directional sliding of the steaming tray, and plays an auxiliary supporting role when the steaming tray enters and exits, saving manpower;

[0022] 4. The box module of the present application is composed of an inner box and an outer box, wherein a polyurethane foam layer is filled in the middle for heat insulation. A high-temperature resistant harness protection tube is buried in the insulation layer of the box module and wrapped by the polyurethane foam layer for passing the harness of the upper control module. The harness passes through the protection tube to the heating module. Such a setting can ensure rapid heating of the steam box shell and prevent rapid heat loss;

[0023] 5. The present application provides a steam guide port for connecting to the heating module under the box module. During installation, only a sealing ring needs to be added to interconnect the box module with the steam generating port of the heating module of any heat source form using bolts. A corrugated mesh anti-impact device is provided in the steam guide port to reduce the risk of scalding caused by steam expansion and spraying to operators who open the door to take food. At the same time, a honeycomb anti-surge plate is also provided in the conduit connected to the steam guide port to prevent the water from boiling during heating, causing water level fluctuations and causing the sensor to misjudge the water level.

[0024] 6. The present application sets an exhaust pipe above the box module, and the exhaust pipe mainly plays two roles here; one is to exhaust air and maintain the pressure problem in the steam box; the second is to install a heavy hammer type boost regulator on the exhaust pipe, and control the steam pressure inside the steam box by adjusting the regulator to solve the problem that the boiling point of water is low in plateaus and high altitude areas, and it is difficult to steam rice and food;

[0025] 7. The main invention of the box module of this application is that the upper and lower parts are fixed with embedded holes. The upper end can be connected to the control module, and the lower end can be connected to the heating module, which is convenient for replacing different control modules and heating modules. The box becomes an independent unit, with advantages 1: it can be disassembled and assembled in a narrow space; 2: it can be freely combined with modules of different configurations; 3: it is easy to carry; 4: it can be reused; 5: it only uses bolts for installation, reducing the requirements for installation tools and skills;

[0026] 8. The door of the steam box housing of the present application is composed of an inner door panel and an outer door panel, and a polyurethane foam layer is filled in the middle for heat insulation; a mechanical temperature display is provided on the door body, which is also installed by bolt fixing, and is used to detect the real-time temperature inside the box body when steaming rice, and is displayed on the instrument on the door;

[0027] 9. The heating module of the present application is generally divided into electric heating, steam heating, gas heating, electromagnetic heating, heat pump heating, etc. according to different heat sources.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Reference Figure 1 and Figure 2 A split modular steam box includes a control module 1, a box module 2 and a heating module 3, wherein the control module 1 is installed above the box module 2, and the heating module 3 is installed below the box module 2.

[0039] The main utility model point of the box module of this application is that the upper and lower embedded holes are installed. The upper embedded hole is used for detachable connection with the control module 1, and the detachable connection here can be fixed by bolts and screws. The lower embedded hole is used for detachable connection with the heating module 3, and the detachable connection here can be fixed by bolts and screws, which is convenient for replacing different control modules and heating modules. The box body is made into three independent units, so that the application can be disassembled into a narrow space and assembled; it can be freely combined with modules of different configurations; it is convenient to carry; it can be reused, and only bolts are used for installation, reducing the requirements for installation tools and skills.

[0040] Reference Figure 1 , Figure 4 and Figure 5The control module 1 includes an upper shell 11, which is installed in isolation from the box module 1 using a high-temperature resistant insulation layer. A circuit board is provided inside the upper shell 11 to control the overall operation of the steamer. An exhaust port 14 connected to the box module 2 is provided at the bottom of the upper shell 11. The top of the exhaust port 14 extends out of the control module 1, and the bottom is connected to an exhaust pipe 27 provided on the top of the box module 2, so that the steam in the box module 2 can be discharged.

[0041] It should be noted that the control module 1 of the present application is placed at the top and can be connected to the heat source control box in the heating module 3 through a wiring harness. It can not only control different heat sources in the heating module 3 (electric heating, steam heating, gas heating, electromagnetic heating, heat pump heating, etc. can be selected), but also a mechanical timer is arranged on the top of the control module 1. Its function is to control the time of steaming rice and steamed buns without changing the basic principle when the steam heat source or the heat pump heat source is not controlled. That is, no matter what kind of heat source is replaced in the heating module 3, the timer can realize timing control; that is, it can be connected in series to the electric heating main circuit (when the heat source is electric heating) to control the contactor; it can also be connected in series to the solenoid valve to control the steam pipe (when the heat source is steam heating).

[0042] At the same time, the control module 1 can also adapt to different heat sources to play the role of control and alarm. That is, no matter what kind of heat source is replaced in the heating module 3, the above control module 1 can play the core function of control and alarm.

[0043] It should be noted that the timer is a passive mechanical on-off control. Although the alarm is active, ships generally have solenoid valves and flow valves for master control when using steam heat sources. Therefore, when directly connecting to a flow meter, heat pump or electromagnetic heat source, the mechanical timer is connected in series in the main circuit to control the electromagnetic main control or heat pump main circuit. In this way, there is basically no need to change any circuits or wiring harnesses to directly replace the heat source.

[0044] Furthermore, a water replenishment button 12, a switch button 13, a timing knob 15, a heating status indicator light, a heating timer, a fault alarm buzzing indicator light, etc. are installed on the front side of the upper shell 11, and the circuit board inside the upper shell 11 is electrically connected to the water replenishment button 12, the lighted switch button 13, the timing knob 15, the heating status indicator light, the heating timer, and the fault alarm buzzing indicator light.

[0045] Reference Figure 1 and Figure 2The box module 2 includes a steam box shell 22, wherein a rotating handle 24 is provided on the front door panel of the steam box shell 22, and a handle clamp 23 corresponding to the rotating handle 24 is provided on one side panel of the steam box shell 22, wherein the front door panel is composed of an inner door panel and an outer door panel, and a polyurethane foam layer is filled in the middle for heat insulation. A mechanical temperature display 21 is provided on the front door panel, which is also installed by bolt fixing, and is used to detect the real-time temperature inside the box when steaming rice, and is displayed on the instrument on the door. The door panel is connected to the box module 2 by a hinge.

[0046] Furthermore, the steamer shell 22 is composed of an inner and outer box body, with a wire harness protection tube buried in the middle, a polyurethane foam layer provided on the outer side of the wire harness protection tube, and the wire harness in the wire harness protection tube is connected to the heating module 3 through the protection tube. The heating module 3 can control the heating of the wire harness, and the wire harness acts on the inside of the steamer shell 22 through the polyurethane foam layer, thereby achieving heating of the steamer shell 22.

[0047] Reference Figure 3 and Figure 8 Steaming plate racks 25 are installed on both sides of the interior of the box module 2. The steaming plate racks 25 include positioning members 252 connected to the inner side of the box module 2. The positioning members 252 are bolts. The outer side of the positioning members 252 is sleeved with a ball bearing 252. A connecting rod 251 is engaged between the two positioning members 252 located on the same horizontal line.

[0048] It should be noted that the steaming plate rack 25 is different from the traditional welded steaming plate rack. The steaming plate rack 25 in the box body of the utility model is not installed by welding, but is fixed by bolts; and the rack body of the steaming plate rack is made of high-quality stainless steel by cold stamping. The ball bearing 252 structure plays a guiding and positioning role to prevent the shaking of the ship during the movement and drive the steaming plate rack 25 to shake. The ball bearing 252 is used to guide the directional sliding of the steaming plate, and plays an auxiliary supporting role when the steaming plate is in and out, saving manpower. The steaming plate rack can be freely disassembled and assembled, fixed with bolts, convenient for maintenance and replacement, reducing the dependence on welding skills, and can be reused.

[0049] Reference Figure 3 and Figure 5A steam guide port 26 for connecting to the heating module 3 is provided at the bottom of the box module 2. During installation, only a sealing ring needs to be added to interconnect the box module with the steam generating port of the heating module in any heat source form using bolts. A corrugated mesh anti-impact device is provided in the steam guide port 26 to reduce the risk of scalding caused by steam expansion and injection to the operator who opens the door to take food; and a honeycomb anti-surge plate is also provided in the conduit connecting the steam guide port 26 and the electric heater 37, that is, a multi-layer honeycomb plate is stacked to form an anti-surge structure, which can pass steam, but the boiling and rising water can offset it. The honeycomb anti-surge plate can ensure that the steam passes normally, while the boiling water is blocked, thereby preventing the water level from fluctuating due to boiling during heating, which causes the sensor to misjudge the water level.

[0050] It should be noted that the arrangement of the steam guide port 26 and the conduit connected thereto in the present application can prevent the heat source water in the heating module 3 from boiling and causing water level fluctuations during heating, which can cause the sensor to misjudge the water level. The corresponding program here has also been optimized and monitored multiple times to obtain differential signals to prevent the boiling of water from being misjudged as "lack of water" when boiling water. The water shortage judgment here uses a water shortage alarm buzzer, which is set on the corresponding heat source of the heating module 3, such as the water shortage alarm buzzer set on the present application. Figure 6 (This application is electric heating) The three water level electrodes on the electric heater 37 detect the high, medium and low water levels, and a small logic board determines the water level change. When the electric heating module is in operation, a water shortage alarm buzzer is sounded;

[0051] However, during steam heating, the water shortage alarm buzzer is connected to the flow meter, and an alarm will also be triggered when the ship's steam system does not supply steam or the air pressure (flow) is insufficient.

[0052] Reference Figure 4 and Figure 5 An exhaust pipe 27 is arranged above the box module 2, and the exhaust pipe 27 can be connected to the exhaust port 14 on the upper shell 11. The exhaust pipe 27 mainly plays two roles here: one is to exhaust air and maintain the pressure problem in the steamer; the second is to install a heavy hammer type boost regulator on the exhaust pipe 27, and control the steam pressure inside the steamer by adjusting the regulator to solve the problem that the boiling point of water is low in plateaus and high altitudes, making it difficult to steam rice.

[0053] Reference Figure 5 , Figure 6 and Figure 7 The heating module 3 includes a heating shell 32 arranged at the bottom of the box module 2, wherein a heating heat source and a circuit control box 35 are arranged inside the heating shell 32, the circuit control box 35 is electrically connected to the heating heat source, and a steam outlet pipe is arranged on the top of the heating shell 32, and the steam outlet pipe is connected to the steam guide port 26 arranged in the box module 2.

[0054] The heating source is generally divided into electric heating, steam heating, gas heating, electromagnetic heating, heat pump heating, etc. according to different heat sources, that is, an electric heating element, a steam heating element, a gas heating element, an electromagnetic heating element, or a heat pump heating element can be set in the heating shell 32. When replacing, there is no need to disassemble the entire heating module 3, and only the corresponding heating source needs to be replaced. The heating module 3 can be designed into different styles according to different working conditions, but they can all be connected to the box module, and have strong applicability.

[0055] Taking the electric heating element as an example, the electric heating element includes an electric heater 37 arranged inside the heating shell 32, and an electric heating tube 374 is installed inside the electric heater 37. A drainage pipe 36 is provided at the bottom of the electric heater 37, wherein a water injection pipe 371 is installed on one side of the electric heater 37, and a solenoid valve 372 and a filter 373 are provided on the water injection pipe 371; water is injected into the electric heater 37 through the water injection pipe 371, and then the steam generated after heating by the electric heating tube 374 enters the box module 2 from the steam guide port 26, so as to realize steam heating of the food in the box module 2. When not in use, the water in the electric heating tube 374 can be discharged from the drainage pipe 36.

[0056] It should be noted that the present application may provide a water receiving trough at the front end of the heating shell 32, which can collect condensed water when the steamer door is opened and closed, and return it to the water injection pipe 371 through a conduit, thereby reusing water resources.

[0057] The specific operating principles of this application are as follows:

[0058] Before use, place the steaming plate in the steamer housing 22, then install the control module 1 on the housing module 2 as needed, and install the heating module 3 under the housing module 2. The control module 1 realizes intelligent control of the entire application, and the heating module 3 is used to heat the housing module 2.

[0059] When in use, the food is placed in the steaming tray, and then the steaming tray is placed in the box module 2, and the steaming tray is supported by the steaming tray shelf 25 in the box module 2, and then electrically heated by the electric heater 37 in the heating module 3, and the generated steam enters the steam box shell 22 from the steam guide port 26, thereby achieving steam heating of the food, and the steam in the steam box shell 22 can finally be discharged from the exhaust pipe 27 and the exhaust port 14; when in use, the temperature display 21 can monitor the temperature in the box module 2 in real time;

[0060] When not in use, the control module 1 and the heating module 3 can be separated from the box module 2 at any time, and the heating unit in the heating module 3 can also be replaced at any time as needed. Regardless of the replacement of various heating units, the external heating shell 32 does not change and can still be directly installed on the bottom of the box module 2, and it is also directly corresponding to the steam guide port 26; the present application solves the problems of large volume and structure of the steamer itself, which is difficult to carry, and the subsequent difficulty in replacing the heating unit by setting up such a detachable mode. At present, the conventional heating unit replacement is to replace all of them, and the heating unit has a different heating principle, so the connection with the box module 2 also needs to be changed accordingly. The external shell of the present application does not change, and the structure corresponding to the box module 2 does not change. Only the internal heating unit is changed, which can adapt to different heating units, such as electric heating, steam heating, gas heating, electromagnetic heating, heat pump heating, etc., and all of the above heating sources can share an external shell.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
