Description

Technical Field

[0001] This invention relates to the field of odor removal technology, and more specifically, to an odor removal device and a steam oven having the same. Background Technology

[0002] During the use of a steam oven, there are two operating modes: high-temperature baking and high-temperature steam. In the high-temperature baking mode, the oven bakes food at high temperatures. The grease and food residue that splatters from the heated food easily accumulates on the inner wall of the oven, making it difficult to clean over time. Furthermore, the food residue adhering to the inner wall hardens under the high-temperature baking process, making subsequent cleaning difficult, especially for small deposits that are hard to remove with a cloth. This can lead to scale buildup, mold growth, or unpleasant odors, posing a health risk. In the high-temperature steam mode, excessive condensation at the bottom of the oven's interior causes high steam content to condense on the food surface before absorbing heat and turning into steam. This excessive condensation can also lead to scale buildup, mold growth, and unpleasant odors inside the oven.

[0003] In existing technologies, plasma is used for odor removal. Atmospheric plasma includes corona discharge, glow discharge, and electric arc discharge. Glow discharge has a plasma density three orders of magnitude higher than that of corona discharge. Therefore, glow discharge can achieve continuous and broad-spectrum decomposition and removal of gaseous pollutants. Glow discharge provides more efficient and faster sterilization through uniform, large-area discharge. Furthermore, the high plasma energy of glow discharge can break the chemical bonds of VOCs, resulting in excellent odor removal. However, in existing glow discharge odor removal technologies, a single power supply typically controls multiple electrode groups. Even with multiple electrode groups connected in parallel, a short circuit in one electrode group can easily cause other electrode groups to malfunction, making the operation of multiple electrode groups unreliable.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please refer to Figure 1 , Figures 4 to 6 This invention provides a deodorizing device, comprising: multiple sets of electrode groups 1, each electrode group 1 including at least one discharge structure 10; the deodorizing device also includes multiple power supply components 9, which are connected one-to-one with the multiple sets of electrode groups 1, so that each power supply component 9 supplies power to its corresponding electrode group 1. With this configuration, when one set of electrode groups 1 malfunctions, the other electrode groups 1 are powered by their corresponding power supply components 9. Thus, damage to one set of electrode groups 1 will not affect the operation of the other sets of electrode groups 1, solving the problem of unreliable operation in existing deodorizing devices.

[0029] Optionally, each power supply component 9 is a battery component; by dividing the electrodes into multiple electrode groups 1, and each multiple electrode group 1 being controlled separately by its own power supply component 9, the low-power power supply component 9 can achieve better stability and reduce the production cost of the deodorizing device. It also has advantages over a single large power supply in terms of subsequent control and reliability of the deodorizing device.

[0030] In the embodiments of this application, each electrode group 1 has multiple discharge structures 10, which are connected in parallel. Each discharge structure 10 includes a paired first electrode 101 and second electrode 102, both of which are electrically connected to a corresponding power supply component 9. This arrangement ensures that if one discharge structure in each electrode group 1 is damaged, the operation of the other discharge structures 10 in each electrode group 1 is not affected to a certain extent, further improving the operational reliability of the deodorization device.

[0031] like Figure 6 As shown, each discharge structure 10 also includes an insulating material 103, which is located between the first electrode 101 and the second electrode 102.

[0032] Specifically, the deodorizing device also includes multiple switching components, with at least one switching component installed on each parallel branch of the multiple discharge structures 10 in each electrode group 1. Thus, when one of the discharge structures 10 in each electrode group 1 experiences a short circuit, the corresponding switching component can be controlled to open. This prevents the short circuit of that discharge structure 10 from damaging the parallel branches of other discharge structures 10, further improving the operational reliability of the deodorizing device.

[0033] In embodiments of this application, the deodorizing device further includes: a plurality of first detection modules 11, each of which is disposed on the circuit between the power supply component 9 and the electrode group 1, with each of the first detection modules 11 corresponding to one of the power supply components 9, to detect the current and / or voltage values ​​between each power supply component 9 and the corresponding electrode group 1; and an energy input module, which includes a voltage input module and a high-voltage AC power generation module, and is connected to the plurality of first detection modules 11 to control the voltage and current input by the energy input module to the plurality of electrode groups 1 according to the detection results of the first detection modules 11. Through the above configuration, the current and / or voltage between each power supply component 9 and the corresponding electrode group 1 can be detected, and the change in current and / or voltage can be used to determine whether the electrode group 1 is damaged. If one of the electrode groups 1 is damaged, the voltage and current input by the energy input module to the remaining normally operating electrode groups 1 increases, thereby increasing the power of the other electrode groups 1 and thus increasing the deodorizing effect of the other electrode groups 1.

[0034] Optionally, the energy input module uses PWM modulation technology to regulate the input voltage and current.

[0035] Specifically, the first detection module 11 includes a current sensor and a voltage sensor, and the first detection module 11 is disposed on the circuit between the output (positive) terminal of the power supply component 9 and the electrode group 1.

[0036] Optionally, the current sensor includes a current transformer, and the voltage sensor includes a voltage transformer.

[0037] In this application, the current sensor is a high-temperature resistant current sensor; the voltage sensor is a high-temperature resistant voltage sensor.

[0038] Optionally, at least one current sensor and at least one voltage sensor are provided on the parallel branches of the multiple discharge structures 10 of each electrode group 1 to detect the operating status of each discharge structure 10.

[0039] Optionally, the current sensor and voltage sensor on each parallel branch are connected to the corresponding switching component to control the switching component's on / off state based on the detection results of the current sensor and voltage sensor.

[0040] In embodiments of this application, the deodorization device further includes: a plurality of second detection modules, each of which is disposed on the circuit between the power supply component 9 and the electrode group 1. The plurality of second detection modules and the plurality of first detection modules 11 of the power supply component 9 are configured in a one-to-one correspondence to obtain the corresponding frequency and amplitude of the power supply component 9 based on the detection results of each first detection module 11; and a control module, which is connected to the plurality of first detection modules 11, the plurality of second detection modules, and the energy input module, to receive the detection results of the plurality of first detection modules 11 and the plurality of second detection modules, and to control the voltage and current input by the energy input module to the plurality of electrode groups 1 based on the detection results of the plurality of first detection modules 11 and the plurality of second detection modules. Through the above configuration, the discharge state of each electrode group 1 can be ensured to be stable.

[0041] Optionally, the second detection module includes an oscilloscope, through which the frequency and amplitude of the current / voltage between each power supply component 9 and the corresponding electrode group 1 can be obtained by the waveform displayed on the oscilloscope.

[0042] Specifically, the control module provides the voltage input module with enable (EN) and PWM waveform control signals to enable the voltage input module to achieve constant voltage input; the control module also provides the high-voltage AC power generation module with PWM waveform control signals to enable the high-voltage AC power generation module to convert DC power into high-frequency high-voltage AC power. Through these settings, the glow discharge operation of electrode group 1 is stabilized.

[0043] Among them, air glow discharge is a phenomenon in which a high voltage and high frequency (typically a voltage of tens of kV and a frequency of several kHz or higher) alternating power supply is applied between two electrodes. It utilizes the characteristic that the change in air polarity lags behind that of the electrodes, causing the air to break down and discharge.

[0044] In the embodiments of this application, the deodorizing device further includes a mounting housing 2, which has multiple mounting spaces 200, each of which is correspondingly arranged with a multiple electrode group 1. The mounting housing 2 is made of heat-insulating material, which further improves the reliability of the deodorizing device when it is used in a steam oven. And / or, each discharge structure 10 is made of ceramic material. Because ceramic has a smooth surface and high uniformity, the discharge structure is more uniform, and ceramic is more resistant to high temperatures, which improves the reliability of the deodorizing device when it is used in a steam oven.

[0045] Optionally, in this application, the multiple deodorizing devices include multiple mounting frames 12, and multiple electrode groups 1 are respectively mounted on the corresponding mounting frames 12. The mounting frames 12 are detachably mounted on the mounting housing 2. This improves the integration of the electrode groups 1 and realizes modular installation of the electrode groups 1.

[0046] Specifically, the mounting frame 12 is provided with a positive electrode connection part 121 and a negative electrode connection part 122, which are arranged in parallel with multiple discharge structures 10.

[0047] In the embodiments of this application, multiple discharge structures of each electrode group 1 are arranged in parallel. In this way, if one or two discharge structures of each electrode group 1 of the deodorizing device break, it will not affect the use of the electrode group 1, and there is no need to replace the entire electrode group 1 of the deodorizing device. The control module receives the voltage and current signals of the discharge structure 10 and automatically adjusts the operating power of the other discharge structures 10 in the electrode group 1. When a large number of discharge structures 10 on an electrode group 1 of the deodorizing device are damaged or at least one discharge structure 10 on an electrode group 1 is short-circuited, the user needs to be reminded to replace the electrode group 1. In this way, only the mounting frame needs to be removed to replace an electrode group 1, reducing the replacement cost.

[0048] In the embodiments of this application, the deodorizing device includes 8 groups of electrodes 1, each group of electrodes 1 having 15 discharge structures 10, and the deodorizing device includes a total of 120 discharge structures 10.

[0049] Optionally, the odor removal device of this application can be used in air purifiers.

[0050] Please refer to Figure 2The present invention also provides a steam oven, comprising: the aforementioned deodorizing device; an oven body 3 having a receiving space 300, wherein at least a portion of the deodorizing device is installed within the receiving space 300 and located at the top and / or bottom of the receiving space 300. By setting the deodorizing device to deodorize the steam oven, the cleanliness of the inside of the steam oven is ensured.

[0051] Optionally, the deodorizing device is detachably installed inside the oven body 3. When the steam oven is needed, the deodorizing device is removed, and after the steam oven is finished, the deodorizing device is reinstalled inside the oven body 3 to prevent the heat emitted by the oven from damaging the deodorizing device. Alternatively, the mounting housing 2 of the deodorizing device is made of heat-insulating material and has a first heat-insulating space. The power supply component 9 is installed in the first heat-insulating space of the mounting housing 2. This can prevent the steam oven from damaging the power supply component 9 during operation. Furthermore, each discharge structure 10 is made of ceramic material, which is heat-resistant and improves the reliability of the deodorizing device when used in the steam oven. Alternatively, the power supply component 9 is installed on the outside of the receiving space 300, and each power supply component 9 is electrically connected to the corresponding electrode group 1.

[0052] Optionally, the power supply component 9 is installed on the outside of the accommodating space 300, and each power supply component 9 is electrically connected to the corresponding electrode group 1 via a wire. The heat insulation component has a first heat insulation space, and the wire is located in the first heat insulation space.

[0053] In an embodiment of this application, the steam oven includes a third detection component 4, which is mounted on the oven body 3. At least a portion of the third detection component 4 is located within a receiving space 300 to detect odors within the receiving space 300. The third detection component 4 is connected to a deodorizing device to control the deodorizing device to start based on the detection result of the third detection component 4. This configuration enables automatic control of the deodorizing device to ensure timely deodorization.

[0054] Specifically, the third detection component 4 is connected to the voltage input module and the high-voltage AC power production module of the energy input module of the deodorizing device to control the energy input module to input constant voltage and AC power to each electrode group 1, so as to control the discharge of multiple discharge structures 10 of each electrode group 1.

[0055] In the embodiments of this application, the third detection component 4 is a high-temperature odor sensor. The third detection component 4 is disposed in the accommodating space 300 to avoid high-temperature damage to the odor sensor during the steaming and baking process of the steam oven, and to ensure the reliability of the operation of the third detection component 4; and / or, a heating component 5 is disposed at the bottom of the accommodating space 300, and the third detection component 4 is located on the side wall of the accommodating space 300, and the third detection component 4 is located on one side of the heating component 5. In this way, the hot air from the heating component 5 can be prevented from flowing directly to the third detection component 4, and the third detection component 4 can be prevented from being damaged by high temperature.

[0056] Optionally, the odor sensor is a sensor with the following characteristics:

[0057] 1. High temperature resistance: This invention uses a suitable high temperature resistant sensor and takes appropriate heat insulation measures to protect the sensor. Some high temperature working condition sensors can withstand temperatures up to 125°C or even higher. These sensors are more suitable for detecting odors in high temperature environments.

[0058] 2. Steam protection: Select a suitable waterproof sensor and take appropriate waterproof measures to protect the sensor;

[0059] 3. Corrosion resistance: Steam ovens may produce some chemicals during the cooking process. Therefore, the odor sensor needs to be corrosion resistant. Choose a suitable corrosion resistant sensor or take appropriate anti-corrosion measures to protect the sensor.

[0060] Optionally, the steam oven also includes a heat insulation component with a second heat insulation space. The third detection component 4 is installed in the third heat insulation space to further prevent the third detection component 4 from being damaged by high temperature and to further improve the reliability of the operation of the third detection component 4.

[0061] In the embodiments of this application, there are multiple third detection components 4, which are respectively disposed on the side walls of the accommodating space 300. Multiple third detection components 4 are disposed on each side wall, and the multiple third detection components 4 on each side wall are spaced apart along the height of the oven body 3. A heating element 5 is disposed at the bottom of the accommodating space 300. The projections of the multiple third detection components 4 on a preset projection surface do not overlap with the projection of the heating element 5 on the preset projection surface, which is parallel to the bottom wall of the oven body 3. This arrangement improves the detection range of the third detection components 4, ensures the reliability of their detection, and prevents the hot air emitted by the heating element 5 from directly flowing towards the third detection components 4, thus preventing damage from high temperatures.

[0062] In the embodiments of this application, the heating component 5 is connected to the third detection component 4 to control the operating state of the heating component 5 according to the detection result of the third detection component 4. With the above settings, when the third detection component 4 detects an odor and needs to deodorize the containment space of the oven body, it controls the heating component 5 to start, so as to perform secondary evaporation of the condensate in the containment space, thereby reducing the residual water in the steam oven and preventing the condensate from accumulating in the containment space and causing mold growth.

[0063] In embodiments of this application, the steam oven further includes a cooling fan 6. The oven body 3 has a feeding opening, and the cooling fan 6 is mounted on the oven body 3 and positioned opposite to the feeding opening. The cooling fan 6 is connected to a third detection component 4 to control its operating state based on the detection results of the third detection component 4. With this configuration, when the third detection component 4 detects an odor and deodorization of the oven body's containment space is required, the cooling fan 6 is activated to dissipate the odor within the containment space 300.

[0064] In this application, there are two deodorizing devices 7, which are respectively installed at the top and bottom of the accommodating space 300.

[0065] In the embodiments of this application, the mounting housing 2 of the deodorizing device 7 includes multiple sequentially connected mounting segments to form a polygonal housing, each mounting segment having an mounting space 200; the multiple mounting segments form a clearance space so that the clearance space of the deodorizing device 7 located at the bottom of the receiving space avoids the heating component 5 at the bottom, and the clearance space of the deodorizing device 7 located at the top of the receiving space 300 can prevent the heat emitted by the heating component 5 from directly contacting the multiple electrode groups 1 of the deodorizing device 7, preventing the multiple electrode groups 1 from being damaged by high temperature, and ensuring the reliability of the operation of the deodorizing device 7.

[0066] Optionally, the steam oven includes a voice module connected to a third detection component 4 to determine whether deodorization is complete based on the odor detected by the third detection component 4, and to control the voice module to issue a voice prompt.

[0067] Optionally, the steam oven includes a display module connected to the third detection component 4 to determine whether deodorization is complete based on the odor detected by the third detection component 4, and to control the display module to pop up a pop-up prompt.

[0068] In the embodiments of this application, the control module of the steam oven includes a temperature sensor controller, which is used to monitor the temperature of the steam oven and keep the temperature stable. When the detected temperature of the steam oven rises abnormally, the temperature of the steam oven can be automatically adjusted to avoid the detection component being affected by overheating or steam.

[0069] Furthermore, the steam oven includes an alarm system. A temperature sensor controller is connected to the alarm system. When the temperature sensor controller detects abnormally high temperature or a malfunction, it sends out an audible and / or visual signal through the alarm system to issue an alarm in a timely manner, so that the user can take timely measures to avoid damaging the aforementioned detection components.

[0070] The controller can record the detection data of the third detection component (odor sensor) to determine whether the odor sensor is damaged or its performance has deteriorated based on the readings and data change trends of the odor sensor. If any abnormality or performance degradation is found, corresponding measures can be taken in time to deal with it, such as replacing the odor sensor in time.

[0071] In addition to relying on the odor sensor's detection data recorded by the controller, the odor sensor can also be regularly maintained and calibrated: even with these measures, the odor sensor's performance may change over time. Therefore, regular maintenance and calibration are necessary to ensure its accuracy and reliability. This can be achieved through methods such as comparison with a standard sensor or using a reference gas.

[0072] In this application, the heating assembly 5 includes multiple heating tubes and multiple connecting wires 8, and adjacent heating tubes are electrically connected by the connecting wires 8.

[0073] Alternatively, the odor sensor can be insulated in the following ways:

[0074] (1) Use air insulation. Utilize the heat insulation properties of air to set up air insulation material around the odor sensor so as to wrap the odor sensor with air insulation material to reduce heat transfer.

[0075] (2) Use heat insulation materials: Add appropriate heat insulation materials between the outer shell of the steam oven and the sensor, and add appropriate heat insulation materials such as asbestos, ceramics, and fibers between the sensor shell and the high-temperature object. This can effectively prevent the transfer of heat and protect the sensor from high temperature.

[0076] (3) Add a protective coating: Add a protective coating to the surface of the odor sensor. This can prevent steam from directly contacting the odor sensor and also has a certain heat insulation effect. The coating material should be selected with good steam resistance and high temperature resistance to block direct contact between heat and steam. Such as ceramic coating, metal coating or special heat insulation coating.

[0077] (4) Isolation Design: The sensor is installed in a separate, well-insulated structure to reduce direct contact with heat and vapor. Materials with good thermal insulation properties, such as ceramics or metals, can be used to construct this structure and ensure its airtightness.

[0078] (5) Ventilation design: Design a reasonable ventilation path for the sensor to guide hot air and steam away from the sensor. This can be achieved by creating vents around the sensor, using ventilation fans, or taking advantage of natural wind direction.

[0079] (6) Distance design: Maximize the distance between the sensor and the heat or steam source to reduce heat and steam transfer. This can be achieved by installing the sensor in a location far away from the heat or steam source.

[0080] (7) Guiding Design: The cavity is not completely isolated from the outside world, but is connected by an air duct until the odor concentration reaches equilibrium after T minutes (the odor generation and odor dissipation within the cavity reach equilibrium). The value of T depends on the type of food the user is cooking, and heat or steam can be directed to a specific area to reduce its impact on the sensor. For example, a deflector or pipe can be used to guide hot air or steam away from the sensor. Figure 3 As shown, in the specific implementation of the steam oven of the present invention, the steam oven has an odor removal mode. After the odor removal function is activated, the control module receives the odor data transmitted in real time by the odor sensor (third detection component 4) and controls the operation of the two odor removal devices according to the detection results of the odor sensor. The first detection module 11 and the second detection module of the odor removal device identify the discharge state of the glow discharge of the odor removal device. The control module of the odor removal device controls the energy input module to input voltage and current to the electrode group 1 of the odor removal device according to the discharge state. After the odor removal is completed, the voice module or the pop-up window on the display board will intelligently remind whether the odor removal is completed. Then, the heating component 5 at the bottom will be activated to perform secondary heating of the condensate in the inner cavity, and perform residual water treatment to reduce the accumulation of condensate and the emission of odor. In addition, the cooling fan 6 will be activated to circulate heat and heat evenly and emit the odor in the purified containment space.

[0081] Optionally, the steam oven's outer casing is equipped with heat dissipation fins to facilitate heat dissipation.

[0082] A steam oven is a kitchen appliance that integrates steaming and baking functions. During the cooking process, the steam oven may produce certain odors, such as food residue and grease. These odors can affect the air quality in the kitchen and may even affect the taste of food. Therefore, how to effectively deal with these odors is a problem that must be solved during the use of the steam oven. Therefore, this application proposes an odor removal device. Through the discharge of the discharge structure 10, this application has the following effects: (1) Oxidative decomposition: The discharge structure 10 generates a large number of active particles, such as electrons, ions and free radicals, during the glow discharge process. These active particles react with odor molecules to decompose the odor molecules into odorless substances, which will not have a negative impact on the human body and food, nor will they damage the equipment itself. This oxidative decomposition reaction can effectively remove various odors, such as fishy smell and burnt smell; (2) Sterilization and mold removal: The active particles generated by the glow discharge can not only react with odor molecules, but also kill bacteria and mold. When these microorganisms come into contact with active particles, they are destroyed by oxidation, radiation, and other processes, thus preventing the generation of odors and the reproduction of bacteria.

[0083] Meanwhile, the deodorizing device of this application is also equipped with a cooling fan 6 to achieve the following effects: after passing through the glow discharge of the discharge structure 10, the decomposed odorless substances can be discharged outside the machine through the cooling fan 6, while cleaning the cooking cavity and exhaust system to prevent the regeneration of odors. This self-cleaning function can maintain the hygiene and cleanliness of the equipment and improve its durability.

[0084] In summary, the deodorizing device of this steam oven achieves deodorization through glow discharge of the discharge structure 10 to realize oxidation decomposition, sterilization, and mold removal, and through the setting of a cooling fan 6 to achieve odor removal by exhausting clean air, thus ensuring the taste of food and the health and safety of users. At the same time, this device also has the advantages of efficient, safe, and convenient cooking functions, providing consumers with a better cooking experience. From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0085] This invention provides a deodorizing device, comprising: multiple sets of electrode groups 1, each electrode group 1 including at least one discharge structure 10; the deodorizing device also includes multiple power supply components, which are connected one-to-one with the multiple sets of electrode groups 1, so that each power supply component supplies power to its corresponding electrode group 1. With this configuration, when one set of electrode groups 1 malfunctions, the other electrode groups 1 are powered by their corresponding power supply components.
