Description

Technical Field

[0001] The invention belongs to the technical field of water supply systems for steam ovens, and in particular relates to a water supply system for steam ovens. Background Art

[0002] Existing steam oven water supply systems generally suffer from fragmented structures and complex layouts. The water supply, evaporator connection, and drainage systems are typically connected via multiple independent pipes. The various functional modules (such as water storage, fluid transport, and waste liquid recovery) lack an integrated design, resulting in a bulky overall system that takes up excessive space within the steam oven. Specifically, water storage, fluid transport, and waste liquid recovery are each designed as separate components, rather than being integrated into a single design. Furthermore, these components are connected via multiple independent pipes, resulting in a larger overall size.

[0003] Furthermore, scattered pipe connections can create a chaotic layout, increasing assembly complexity and potentially leading to leaks due to the excessive number of pipe connections. This also hinders subsequent maintenance and repair. Furthermore, traditional systems rely on a single liquid level monitoring method, often relying on a single sensor or mechanical structure. This carries the risk of inaccurate monitoring or failure, making it difficult to ensure reliable water supply. Summary of the Invention

[0004] The object of the present invention is to provide a water supply system for a steam oven to solve the problems raised in the above background technology.

[0005] In view of this, the present invention provides a steam oven water supply system, comprising an integrated matrix with a partition processing function, on which a fluid interaction component, a state sensing component and an air pressure balance component are integrated. The fluid interaction component is used to realize the directional introduction, homogenized fusion and targeted export of different types of fluids. The state sensing component captures the fluid state characteristics in each partition in a non-contact manner. The air pressure balance component is used to eliminate the air pressure gradient between the inside of the integrated matrix and the external environment. The fluid interaction component, the state sensing component and the air pressure balance component are integrated through spatial structured integration to form an integrated functional carrier.

[0006] In the present invention, a further implementation scheme is that the partitioned processing space of the integrated substrate includes a first chamber and a second chamber, the first chamber is configured to receive the initial fluid to be fused and complete the fusion process, and the second chamber is configured to receive the waste fluid refluxed from the outside and realize temporary storage and discharge, the cavity walls of the first chamber and the second chamber are constructed of corrosion-resistant materials, and the volume ratio of the two can be adaptively configured according to the fluid processing requirements.

[0007] In the present invention, a further implementation scheme is that the fluid interaction component includes a multi-media introduction module, a mixed fluid delivery module and a waste liquid discharge module. The multi-media introduction module can respectively connect to the purification fluid and the functional fluid, and introduce them into the first chamber through a selective conduction mechanism. The mixed fluid delivery module is used to transport the fused fluid in the first chamber to the evaporator of the steamer oven. The waste liquid discharge module is used to discharge the waste fluid temporarily stored in the second chamber to the outside. The multi-media introduction module, the mixed fluid delivery module and the waste liquid discharge module form a switchable fluid transmission path through an internal flow channel matrix.

[0008] In the present invention, a further implementation scheme is that the multi-media introduction module includes a purification fluid access submodule and a functional fluid access submodule, the purification fluid access submodule is provided with an opening and closing mechanism for controlling the on and off of the purification fluid, the functional fluid access submodule is provided with a power mechanism for driving the flow of functional fluid, the mixed fluid delivery module is provided with a boosting mechanism for increasing the mixed fluid delivery pressure, and the waste liquid discharge module is provided with a delivery mechanism for driving the flow of waste fluid, and the operating parameters of the power mechanism, boosting mechanism and delivery mechanism can be dynamically adjusted according to the characteristics of the fluid flowing through.

[0009] In the present invention, a further implementation scheme is that a fluid fusion mechanism is provided in the first chamber, and the fluid fusion mechanism can produce regular movement under external stimulation to promote the purification fluid and the functional fluid entering the first chamber to form a homogenized fusion body, and the movement characteristics of the fluid fusion mechanism can be adaptively regulated according to the homogeneity requirements of the fusion body.

[0010] In the present invention, a further implementation scheme is that the state sensing component includes a first sensing module and a second sensing module, the first sensing module is arranged on the outside of the integrated matrix corresponding to the first chamber, and is used to capture the fluid level characteristics in the first chamber, and the second sensing module is arranged on the outside of the integrated matrix corresponding to the second chamber, and is used to capture the fluid level characteristics in the second chamber. The state sensing component also includes an information feedback mechanism, which can present the characteristics captured by the first sensing module and the second sensing module in a visual form. The first sensing module and the second sensing module both use non-contact detection elements, and their detection ends are in contact with the outer wall of the chamber of the integrated matrix or maintain a preset distance, and are not in direct contact with the fluid in the chamber. By identifying the reflection, refraction or disturbance characteristics of the fluid to the detection signal, the fluid state characteristics such as liquid level height and liquid level change rate are indirectly captured.

[0011] In the present invention, a further implementation scheme is that a mechanical sensing mechanism is provided in the first chamber, and the mechanical sensing mechanism can generate displacement as the liquid level in the first chamber changes. When displaced to a preset position, the mechanical sensing mechanism generates a mechanical trigger signal, and the mechanical trigger signal and the electrical signal captured by the first perception module form a dual state judgment reference.

[0012] In the present invention, a further implementation scheme is that the air pressure balance component includes a first air pressure balance path and a second air pressure balance path. The first air pressure balance path is connected to the first chamber and is used to eliminate the air pressure fluctuations in the first chamber during the fluid inflow and outflow process. The second air pressure balance path is connected to the second chamber and is used to eliminate the air pressure fluctuations in the second chamber during the fluid inflow and outflow process. The ends of the first air pressure balance path and the second air pressure balance path are both provided with a breathable and leak-proof mechanism to prevent fluid leakage while achieving gas circulation.

[0013] In the present invention, a further implementation scheme is that the connection parts of the multi-media introduction module, the mixed fluid delivery module and the waste liquid discharge module are all provided with a sealing reinforcement mechanism. The sealing reinforcement mechanism is made of elastic material and can produce adaptive deformation according to changes in the connection state to ensure the sealing efficiency in different connection scenarios.

[0014] In the present invention, a further implementation scheme is that the first chamber and the second chamber are spatially separated and associated through an integrated flow channel matrix inside the integrated base body, and the direction of the flow channel matrix forms a cross structure with a preset angle with the layout of the first chamber and the second chamber, so that the import and export paths of the fluid interaction component and the positions of the first chamber and the second chamber form the shortest transmission distance; the internal flow channel matrix adopts a layered nested design, the flow channel of the multi-media import module is located in the upper layer of the integrated base body, the flow channel of the mixed fluid delivery module is located in the middle layer, and the flow channel of the waste liquid discharge module is located in the lower layer, and the flow channels of each layer are selectively connected through vertical connecting holes; the first air pressure balance path and the second air pressure balance path are symmetrically distributed along the edge of the integrated base body, and form a non-cross spatial layout with the flow channel of the fluid interaction component to avoid mutual interference between air pressure regulation and fluid transmission.

[0015] The beneficial effects of the present invention are: The integrated matrix spatially integrates components such as fluid interaction, state sensing, and air pressure balance into an integrated functional carrier. This replaces the traditional system's dispersed piping pattern for water supply, evaporator connection, and drainage, significantly reducing the use of independent piping and enabling an integrated layout for each functional module (fluid mixing, transportation, waste liquid recovery, etc.). The multiple chambers for fluid mixing, transportation, and waste liquid recovery are integrated into a single integrated matrix, which serves as the main body. This significantly reduces the overall volume, freeing up internal space within the steamer oven and simplifying the assembly process, addressing the bulk and assembly difficulties inherent in the dispersed and complex layout of traditional systems. The internal flow channel matrix design of the fluid interaction components works in tandem with multiple modules, coupled with a reinforced sealing mechanism at the connection points, reducing the number of interfaces in traditional dispersed piping and minimizing the risk of leakage caused by excessive interfaces. Furthermore, the integrated structure allows for a regular layout of functional components, facilitating subsequent maintenance and repair, addressing the maintenance difficulties associated with the chaotic piping in traditional systems. The state sensing component utilizes a non-contact sensing module and a mechanical sensing mechanism within the first chamber to form a dual state judgment benchmark, replacing the traditional system's single liquid level monitoring method. Through the redundant design of electrical and mechanical signals, the accuracy and reliability of liquid level monitoring are improved, the risk of failure of a single monitoring method is reduced, and the stable operation of the water filling process is guaranteed. Furthermore, the air pressure balancing component eliminates chamber air pressure fluctuations through a dedicated path, avoiding fluid flow obstruction caused by air pressure imbalance. Combined with the adjustable design of the fluid fusion mechanism, the stability and efficiency of the system are further ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present embodiment provides a steam oven water supply system, including an integrated matrix with a partitioned processing function. The integrated matrix serves as the structural carrier and functional core of the entire system. The interior of the integrated matrix is ​​physically separated to form independent and collaborative processing spaces, and the exterior integrates various functional components through a structural layout. The integrated matrix is ​​integrated with a fluid interaction component, a state perception component, and an air pressure balance component. The fluid interaction component realizes the directional introduction, homogenized fusion, and targeted export of different types of fluids (such as purified water, functional solutions, etc.) through a multi-path design and a power control mechanism, ensuring that the fluids are oriented in the system according to the preset logic. flow; the state sensing component adopts the principle of non-contact detection, and provides data support for system operation by capturing and analyzing the state characteristics of the fluid such as liquid level and pressure in each partition in real time; the air pressure balance component dynamically eliminates the air pressure gradient between the inside and external environment of the integrated matrix through a dedicated channel design and a breathable control structure, thereby avoiding fluid transportation obstruction or chamber deformation caused by air pressure imbalance; the fluid interaction component, the state sensing component and the air pressure balance component are integrated through spatial structure to form an integrated carrier with a functional closed loop on the integrated matrix, and the components realize efficient interaction between signals and fluids through internal lines and flow channels.

[0023] In this embodiment, the partitioned processing space of the integrated substrate includes a first chamber 10 and a second chamber 11. The two chambers are physically isolated by a high-strength barrier to avoid cross-contamination between different fluids; the first chamber 10 is configured to receive the initial fluid to be fused (such as purified water and citric acid water) and complete the fusion process; the second chamber 11 is configured to receive the waste fluid refluxed from the outside (such as evaporator condensate) and realize temporary storage and discharge.

[0024] The walls of the first chamber 10 and the second chamber 11 are constructed of food-grade corrosion-resistant materials (such as 316 stainless steel or modified polytetrafluoroethylene), which can withstand long-term erosion by acidic and alkaline fluids. The volume ratio of the two can be adaptively configured according to the fluid processing requirements such as the rated power and single processing volume of the steam oven. For example, for a large-capacity steam oven, the volume of the first chamber 10 can be increased to increase the mixed fluid reserve, while matching the waste liquid temporary storage capacity of the second chamber 11.

[0025] In this embodiment, the fluid interaction component includes a multi-media introduction module, a mixed fluid delivery module and a waste liquid discharge module. The three modules form an organic whole through the flow channel network inside the integrated base body; the multi-media introduction module is provided with an independent access port and a control unit, which can be connected to the purification fluid (such as tap water or purified water that meets the drinking standard) and the functional fluid (such as citric acid solution for cleaning or regulating water quality) respectively, and through the built-in selective conduction mechanism (such as the electromagnetic reversing valve group) according to the preset program, they are introduced into the first chamber 10 separately or simultaneously; the mixed fluid delivery module is equipped with a power device and a flow regulating structure for The fused fluid in the first chamber 10 is delivered to the evaporator of the steam oven at a set pressure and flow rate to meet the water supply demand of the evaporator; the waste liquid discharge module uses a one-way flow channel and a power component to export the waste fluid temporarily stored in the second chamber 11 to an external collection device or drainage system along a specified path; the multi-media introduction module, the mixed fluid delivery module and the waste liquid discharge module form a switchable fluid transmission path through an internal flow channel matrix. The flow channel matrix adopts a modular design and can switch different fluid conduction combinations according to actual usage scenarios (such as normal water supply, cleaning mode, emptying maintenance, etc.) to ensure precise control of the fluid path under various working conditions.

[0026] In this embodiment, the multi-medium introduction module includes a purified fluid access sub-module and a functional fluid access sub-module, both of which are provided with anti-backflow structures to avoid fluid backflow; the purified fluid access sub-module is provided with an opening and closing mechanism (such as an electromagnetic stop valve) for controlling the on-off of purified fluid, which can receive external control signals to realize precise switching and has a manual emergency operation function; the functional fluid access sub-module is provided with a power mechanism (such as a micro-metering pump) for driving the flow of functional fluid, which can quantitatively deliver functional fluid according to the set dose, ensuring that the mixing ratio of purified fluid is accurately controllable; the mixed fluid delivery module is provided with a pressure boosting mechanism for boosting the delivery pressure of mixed fluid, which can adjust the output pressure according to the real-time demand of the evaporator, avoiding pipe damage due to excessive pressure or slow water filling due to insufficient pressure; the waste liquid discharge module is provided with a delivery mechanism (such as an impeller pump 112) for driving the flow of waste fluid, which has a dry running protection function and can automatically stop after the waste liquid is discharged; the operating parameters (such as speed, output pressure, flow, etc.) of the power mechanism, pressure boosting mechanism and delivery mechanism can be dynamically adjusted according to the characteristics (such as viscosity, impurity content) of the fluid flowing through, for example, automatically reducing the speed when delivering particles-containing fluid to reduce wear, and increasing the speed when delivering low-viscosity fluid to improve efficiency.

[0027] In this embodiment, the first chamber 10 is provided with a fluid fusion mechanism, which is the core structure for realizing the homogeneous mixing of fluids and includes a driving unit and an execution unit; the fluid fusion mechanism can produce regular motion (such as rotation, reciprocating swing or vortex stirring) under external excitation (such as electromagnetic drive or motor driving), which promotes the purified fluid and functional fluid entering the first chamber 10 to fully contact through shearing, convection and other actions, forming a homogeneous fusion body with uniform composition; the motion characteristics (such as speed, swing frequency, stirring trajectory) of the fluid fusion mechanism can be adaptively regulated according to the homogeneity requirements of the fusion body, for example, the motion frequency can be increased for scenes requiring rapid mixing, and low-speed stirring can be used for fluids prone to foaming, and its operating state can be closed-loop adjusted through the feedback signal of the state perception component to ensure stable mixing effect.

[0028] In this embodiment, the state sensing component includes a first sensing module and a second sensing module. Both modules use non-contact detection technology to avoid direct contact with the fluid, reducing the risk of contamination and maintenance costs. The first sensing module is arranged on the outer wall of the integrated base corresponding to the first chamber 10, and its detection area covers the high and low liquid level intervals of the first chamber 10, which is used to accurately capture the fluid level characteristics (such as real-time liquid level height and liquid level change rate) in the first chamber 10. The second sensing module is arranged on the outer wall of the integrated base corresponding to the second chamber 11, and its detection range is adapted to the volume design of the second chamber 11, which is used to capture the fluid level characteristics in the second chamber 11. The state sensing component also includes an information feedback mechanism, which is composed of a signal processing unit and a display unit. It can process the characteristic signals captured by the first sensing module and the second sensing module and present them in a visual form (such as an indicator light, a digital display screen or a communication signal output), which not only facilitates the user to intuitively understand the system status, but also provides signal input for automatic control. Specifically, "non-contact" refers to a technical approach in which the state sensing component's detection unit does not physically contact the fluid within the chamber, but instead acquires fluid state characteristics through indirect detection principles. Specifically, the first and second sensing modules are mounted on the outer walls of the integrated substrate, corresponding to the first and second chambers 10 and 11, respectively. The detection signals emitted by their detection elements (such as infrared sensors) penetrate (or are reflected by) the chamber walls. As the liquid level within the chamber changes, the signal's propagation path, intensity, or frequency change accordingly. The sensing modules analyze these changing signals to calculate state parameters such as the real-time liquid level. This approach avoids direct contact between the detection elements and the fluid, reducing the risk of fluid corrosion and contamination of the detection elements, while also minimizing failures caused by mechanical wear of contact components (such as the float rod). The first sensing module uses an infrared dual-tube sensor, with its transmitter and receiver mounted at corresponding positions on the outer wall of the first chamber 10. When the liquid level in the first chamber 10 rises to a level that blocks the infrared light, the signal strength at the receiver drops sharply, indicating that the liquid level has reached a preset threshold. The second sensing module uses a capacitive level gauge, with its detection electrode attached to the outer wall of the second chamber 11. The sensor measures the change in capacitance between the fluid (conductive medium) and the electrode within the chamber, converting it into the real-time liquid level. Neither sensor directly contacts the fluid within the chamber, capturing state characteristics through non-contact signal detection.

[0029] In the embodiment, the first chamber 10 is provided with a mechanical sensing mechanism, which takes a mechanical floating ball as a core executive component. The floating ball is connected to a trigger switch through a connecting rod and is installed above the fluid path between the water inlet valve 6 and the first diaphragm pump 3. The mechanical sensing mechanism can produce vertical displacement with the change of the liquid level in the first chamber 10. When the liquid level rises to a preset high water level position, the floating ball drives the connecting rod to trigger the switch to form a mechanical trigger signal. The mechanical trigger signal and the electrical signal captured by the first sensing module form a double-state judgment reference. Both of them can work independently or can be compared and verified through a logic judgment unit. When one of the signals is abnormal, the system can maintain the basic function according to the other signal, which significantly improves the reliability and fault tolerance of the liquid level monitoring.

[0030] In the embodiment, the air pressure balancing assembly includes a first air pressure balancing path and a second air pressure balancing path. Both paths are made of corrosion-resistant pipelines, and the connection position with the chamber is located at the highest position of the chamber top to ensure complete exhaust. One end of the first air pressure balancing path is in communication with the inside of the first chamber 10, and the other end extends to the outside of the integrated base body, which is used to real-time eliminate the internal air pressure fluctuation during the fluid inlet and outlet of the first chamber 10, to avoid fluid delivery difficulty caused by excessive positive pressure or chamber deformation caused by excessive negative pressure. One end of the second air pressure balancing path is in communication with the inside of the second chamber 11, and the other end also extends to the outside, which is used to eliminate the air pressure fluctuation of the second chamber 11 during the receiving and discharging of waste liquid. The ends of the first air pressure balancing path and the second air pressure balancing path are both provided with a breathable leak-proof mechanism (such as a composite waterproof breathable film), which adopts a micron-sized pore structure, can allow gas to flow freely to balance air pressure, and can effectively prevent liquid leakage. At the same time, it has dustproof and antibacterial functions, which can prevent external pollutants from entering the chamber.

[0031] In this embodiment, the connection parts of the multi-media introduction module, the mixed fluid delivery module and the waste liquid discharge module (such as the pipeline interface, the pump body and the chamber connection end) are all provided with a sealing reinforcement mechanism. The mechanism is made of food-grade elastic material (such as silicone rubber or fluororubber), and its cross-section is designed to adapt to the special-shaped contour of the connection structure; the sealing reinforcement mechanism can produce adaptive deformation according to changes in the connection state (such as assembly pressure, dimensional changes caused by temperature fluctuations), and achieve tight sealing by filling the connection gap. Even under long-term vibration or fluid pressure shock, it can still maintain good sealing performance, ensuring the sealing efficiency in different connection scenarios (such as the initial assembly, long-term operation, and reinstallation after maintenance), and effectively preventing fluid leakage. The process of the steam oven water supply system and the evaporator working together is as follows: the mixed fluid delivery module of the fluid interaction component transports the fluid in the first chamber 10 that has been homogenized and fused by the fluid fusion mechanism to the evaporator through a pressurization mechanism, providing the evaporator with the fluid medium required for work; the waste fluid (such as condensed water) generated during the operation of the evaporator flows back to the second chamber 11 through a dedicated path for temporary storage, and then is exported to the outside by the delivery mechanism of the waste liquid discharge module; during this period, the state sensing component monitors the liquid level status of the first chamber 10 and the second chamber 11 in real time, and the air pressure balancing component balances the air pressure fluctuations caused by the fluid in and out and the interaction between the evaporators in the two chambers through the first and second air pressure balancing paths respectively. The sealing reinforcement mechanism of each connection part ensures the sealing performance of the fluid when it flows between the system and the evaporator, forming a complete closed loop from fluid supply to evaporator utilization to waste liquid recovery.

[0032] "Spatial structuring" is achieved through the spatial layout design of the internal flow channels and components of the integrated matrix: the first chamber 10 and the second chamber 11 are spatially separated and associated with each other by means of an integrated flow channel matrix. The direction of the flow channel matrix and the layout of the two chambers form a preset angle intersection structure, so that the import and export paths of the fluid interaction components are as short as possible from the two chambers; the internal flow channel matrix adopts a layered nested design, with the flow channel of the multi-media import module located in the upper layer of the integrated matrix, the flow channel of the mixed fluid delivery module located in the middle layer, and the flow channel of the waste liquid discharge module located in the lower layer. The flow channels of each layer are selectively connected through vertical connecting holes; at the same time, the first air pressure balance path and the second air pressure balance path are symmetrically distributed along the edge of the integrated matrix, and form a non-intersecting spatial layout with the flow channels of the fluid interaction components to avoid mutual interference between air pressure regulation and fluid transmission. Through the angle design of the flow channels, the layered layout and the symmetrical non-intersecting distribution of the components, the spatial structural integration of various functional components is achieved. Example 2:

It greatly reduces the use of redundant pipes, not only saving internal space of the steam oven, but also reducing the operational difficulty caused by the complex pipes during the assembly process; at the same time, the integrated structure of the steam oven water supply device reduces the excessive pipe interfaces in the traditional decentralized layout, reducing the risk of leakage from the source, and combined with the functional division of the first chamber 10 and the second chamber 11, the mixing path of purified water and citric acid water and the recovery path of the evaporator waste liquid are clearly separated, avoiding fluid interference; in addition, the combination of the high and low water level non-contact sensor 103 and the low water level non-contact sensor 103 on the outside of the first chamber 10 and the internal mechanical float, the non-contact circuit board 114 on the outside of the second chamber 11 and the status feedback of the three indicator lights form an efficient monitoring and feedback mechanism under the integrated framework, further improving the stability and reliability of the system operation, and also providing convenience for subsequent maintenance.

The direction of the flow channel matrix and the layout of the two chambers form a preset angle intersection structure, so that the import and export paths of the fluid interaction components are the shortest from the two chambers. The internal flow channel matrix adopts a layered nested design. The flow channel of the multi-media import module is located in the upper layer of the integrated base, the flow channel of the mixed fluid delivery module is located in the middle layer, and the flow channel of the waste liquid discharge module is located in the lower layer. The flow channels of each layer are selectively connected through vertical connecting holes. At the same time, the first air pressure balance path and the second air pressure balance path are symmetrically distributed along the edge of the integrated base, and form a non-intersecting spatial layout with the flow channels of the fluid interaction components to avoid mutual interference between air pressure regulation and fluid transmission. Through the angle design of the flow channels, the layered layout and the symmetrical non-intersecting distribution of the components, the structural integration of various functional components in space is achieved.
