Description

Technical Field

[0001] This invention relates to the field of kitchen appliances, and more particularly to a kitchen air purification structure, an integrated stove, and a kitchen air purification method. Background Technology

[0002] Cooking produces a lot of oil fumes, and prolonged exposure to these fumes can harm a user's health. Furthermore, the fumes adhere to cookware and walls, making cleaning difficult. Therefore, most families install range hoods to alleviate this problem. Integrated cooktops, which combine a range hood, cooktop, disinfection cabinet, and steam oven into one appliance, offer advantages such as space saving, effective fume extraction, energy efficiency, and environmental friendliness, making them a top choice for many families during renovations.

[0003] Integrated cooktops not only remove cooking fumes produced during stove use but also expel polluted air from the kitchen. When users feel the air quality is poor, they can turn on the integrated cooktop and activate the range hood to remove the polluted air. However, this method only removes polluted air from open spaces within the kitchen. Gas leaks can accumulate in the cooktop's installation space, posing risks of poisoning and explosion over time. Similarly, the installation spaces of functional components like disinfection cabinets often contain high-temperature, high-humidity, and odorous gases. The above method is not applicable to polluted air in enclosed spaces such as the cooktop and disinfection cabinet installation areas.

[0004] Therefore, there is an urgent need to propose a kitchen air purification structure to solve the above problems. Summary of the Invention

[0005] Based on the above problems, the first objective of this invention is to provide a kitchen air purification structure that can not only remove poor-quality air from the open space of the kitchen, but also remove poor-quality air from the installation space of functional components, thereby improving the comfort and safety of kitchen use.

[0006] The second objective of this invention is to provide an integrated stove that, by applying the aforementioned kitchen air purification structure, can maintain the air quality in both open and enclosed installation spaces within the kitchen, thereby improving user comfort and safety when using the kitchen.

[0007] The third objective of this invention is to provide a kitchen air purification method based on the aforementioned integrated stove, which can not only remove poor-quality air from the open space of the kitchen, but also remove poor-quality air from the installation space of the functional components, thereby improving the comfort and safety of kitchen use.

[0008] To achieve the above objectives, the following technical solution is provided:

[0009] A kitchen air purification structure, comprising:

[0010] A branch air quality detector is installed in an installation space, the installation space being used to install functional components, and the branch air quality detector being used to detect the air quality in the installation space.

[0011] A connecting channel, one end of which is connected to the installation space, and the other end of which can be selectively connected to the exhaust pipe of the range hood according to the detection results of the branch air quality detector.

[0012] As a preferred embodiment of a kitchen air purification structure, the number of installation spaces is multiple;

[0013] The connection channel includes a main pipeline and multiple branch pipelines. One end of the main pipeline can be connected to the exhaust pipe. Each of the multiple branch pipelines corresponds to a single installation space. Both ends of each branch pipeline are connected to the main pipeline and the corresponding installation space, respectively.

[0014] As a preferred embodiment of a kitchen air purification structure, each of the branch pipes is equipped with a branch switch valve between it and the corresponding installation space.

[0015] As a preferred embodiment of a kitchen air purification structure, each of the aforementioned installation spaces is equipped with a branch air quality detection device.

[0016] As a preferred embodiment of a kitchen air purification structure, a main switch valve is provided between the connecting channel and the exhaust pipe.

[0017] As a preferred embodiment of kitchen air purification structure, the range hood is equipped with an external air quality detection device on its outer casing.

[0018] As a preferred solution for kitchen air purification structures, the connecting channel is embedded inside the mounting wall.

[0019] The present invention also provides an integrated stove, including functional components and a range hood, wherein the functional components are installed in an installation space, and the integrated stove further includes the kitchen air purification structure described above.

[0020] The present invention also provides a kitchen air purification method, based on the above-mentioned integrated stove, comprising the following steps:

[0021] Branch-line air quality detection devices measure the internal air quality index in the installation space.

[0022] When the internal air quality index is greater than or equal to a first preset value, the connecting channel is connected to the exhaust pipe of the range hood, and the range hood is started.

[0023] As a preferred embodiment of the kitchen air purification method, the kitchen air purification method further includes:

[0024] The external air quality sensor detects the external air quality index outside the installation space;

[0025] When the external air quality index is greater than or equal to the second preset value, the range hood is activated.

[0026] The beneficial effects of this invention are as follows:

[0027] The kitchen air purification structure provided by this invention allows for the connection of a connecting channel to an exhaust duct when the branch air quality detector detects poor air quality in the installation space. This activates the range hood, which absorbs air from the open kitchen space and exhausts it through the exhaust duct. During this process, a negative pressure is created at the connection between the exhaust duct and the connecting channel, effectively removing the poor-quality air from the installation space connected to the connecting channel. This improves the comfort and safety of kitchen use. The kitchen air purification structure is simple, easy to install, and has low processing costs.

[0028] The integrated stove provided by this invention, by applying the above-mentioned kitchen air purification structure, can maintain the air quality in both open and enclosed installation spaces within the kitchen, thereby improving the user's comfort and safety when using the kitchen.

[0029] The kitchen air purification method provided by this invention, based on the aforementioned integrated stove, can not only remove poor-quality air from the open space of the kitchen, but also remove poor-quality air from the installation space of functional components, thereby improving the comfort and safety of kitchen use.

[0042] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0045] like Figures 1-3As shown, this embodiment provides an integrated cooktop, which includes functional components and a range hood 200. The functional components are installed in an installation space 100. The functional components include, but are not limited to, a cooktop system, a disinfection device, a steam oven, and a dishwasher. The functional components are installed in an installation cabinet, and the internal space of the installation cabinet forms the aforementioned installation space 100.

[0046] This integrated cooktop not only removes cooking fumes generated during stove use but also removes polluted air from the kitchen. When users feel the air quality in the kitchen is poor, they can turn on the integrated cooktop and activate the range hood 200 to expel the polluted air. However, this method only removes polluted air from open spaces within the kitchen. It is not suitable for polluted air in enclosed spaces like the installation space 100.

[0047] To address the aforementioned issues, this embodiment also provides a kitchen air purification structure. This structure includes a branch air quality detection component 1 and a connecting channel 2. The branch air quality detection component 1 is disposed in an installation space 100, which is used to install functional components. The branch air quality detection component 1 is used to detect the air quality in the installation space 100. One end of the connecting channel 2 is connected to the installation space 100, and the other end of the connecting channel 2 can selectively connect to the exhaust pipe 201 of the range hood 200 based on the detection result of the branch air quality detection component 1. When the branch air quality detector 1 detects poor air quality in the installation space 100, the connecting channel 2 can be connected to the exhaust pipe 201, and the range hood 200 can be activated. The range hood 200 can absorb air from the open space of the kitchen and exhaust it through the exhaust pipe 201. During the exhaust process, a negative pressure will be formed at the connection between the exhaust pipe 201 and the connecting channel 2, thereby achieving the effect of exhausting the poor-quality air in the installation space 100 connected to the connecting channel 2, thus improving the comfort and safety of kitchen use. This kitchen air purification structure has a simple structure, makes full use of the performance of the range hood 200, does not require the addition of a new fan, is easy to install, and has low processing costs, thus realizing the versatility of the range hood 200's function. Optionally, the branch air quality detector 1 is an air quality sensor, which is existing technology. This embodiment does not describe the specific structure and detection principle of the branch air quality detector 1 in detail.

[0048] Furthermore, there are multiple installation spaces 100; the connecting channel 2 includes a main pipe 21 and multiple branch pipes 22. One end of the main pipe 21 can be connected to the exhaust pipe 201, and the multiple branch pipes 22 correspond one-to-one with multiple installation spaces 100. The two ends of each branch pipe 22 are connected to the main pipe 21 and the corresponding installation space 100, respectively, so as to ensure that the poor quality air in each installation space 100 can be discharged.

[0049] It is understandable that multiple installation spaces 100 are interconnected via connecting channels 2, allowing air to circulate between them. If air from the installation space 100 containing the cooktop system flows into the installation space 100 containing the dishwasher, a safety hazard may occur. In this embodiment, each branch pipe 22 is equipped with a branch switch valve 3 between itself and its corresponding installation space 100. This arrangement prevents air from circulating between the installation spaces 100, further improving the safety of the integrated cooktop.

[0050] Specifically, a first connecting hole corresponding to a plurality of branch pipes 22 is provided on the side wall of the main pipe 21, and each branch pipe 22 is connected to the main pipe 21 through the corresponding first connecting hole; the control system of the integrated stove can drive the branch switch valve 3 to open or block the corresponding first connecting hole.

[0051] Optionally, each installation space 100 is equipped with a branch air quality detection element 1. The air in each installation space 100 can be discharged independently, saving energy and improving emission efficiency.

[0052] Furthermore, a main switch valve 4 is installed between the connecting channel 2 and the exhaust pipe 201. When the user only needs to exhaust the poor-quality air in the open space of the kitchen, they only need to open the main switch valve 4, while keeping the multiple branch switch valves 3 in the closed state, thus avoiding energy waste.

[0053] Specifically, a second connecting hole for connecting to the main pipe 21 is provided on the side wall of the exhaust pipe 201. The integrated stove's control system can drive the main switch valve 4 to open or block the corresponding second connecting hole. The main switch valve 4 includes a movable component, the outer wall of which can fit against the inner wall of the exhaust pipe 201. By driving the movable component to slide up and down along the inner wall of the main pipe 21, the second connecting hole can be opened or blocked. Compared with other methods such as rotation, the sliding movable component has a simple structure and stable control effect.

[0054] Furthermore, an external air quality detector 5 is installed on the outer casing of the range hood 200. The external air quality detector 5 is used to detect the air quality within the open space of the kitchen. The range hood 200 can automatically start based on the detection results of the external air quality detector 5, and, in conjunction with the branch air quality detector 1, achieve automatic air purification within the open kitchen space and the installation space 100, further enhancing the user experience. Optionally, the external air quality detector 5 is an air quality sensor, which is existing technology. The specific structure and detection principle of the external air quality detector 5 will not be described in detail in this embodiment.

[0055] Optionally, in this embodiment, there are two external air quality detectors 5, which are respectively disposed on both sides of the outer shell of the range hood 200 to achieve accurate detection of air quality in the open space of the kitchen.

[0056] Furthermore, the connecting channel 2 is embedded within the mounting wall to maintain the cleanliness and aesthetics of the kitchen. Of course, in other embodiments, the connecting channel 2 can also be separately located on the outside of the mounting wall for easier installation.

[0057] This embodiment also provides a kitchen air purification method based on the above-mentioned integrated stove. The kitchen air purification method includes the following steps: the branch air quality detection device 1 detects the internal air quality index in the installation space 100; when the internal air quality index is ≥ a first preset value, the connecting channel 2 is connected to the exhaust pipe 201 of the range hood 200, and the range hood 200 is started.

[0058] It should be noted that the first preset value can be the value entered by the designer into the integrated stove control system before the integrated stove leaves the factory, or it can be the value entered by the user into the integrated stove control system according to the actual use environment. This implementation does not limit the first preset value, as long as it can meet the safety requirement of 100 mm of installation space.

[0059] Specifically, the branch air quality detector 1 detects the internal air quality index (AQI) of the air in the installation space 100 and transmits it to the control system of the integrated stove. The control system compares the AQI with a first preset value. When the AQI is greater than or equal to the first preset value, the control system controls the main switch valve 4 and the corresponding branch switch valve 3 to open and starts the range hood 200, thereby purifying the air in the corresponding installation space 100. It can be understood that this integrated stove, while purifying the air in the installation space 100, can also purify the air in the open space of the kitchen.

[0060] Furthermore, the kitchen air purification method also includes: the external air quality detection device 5 detects the external air quality index outside the installation space 100; when the external air quality index is ≥ a second preset value, the range hood 200 is started.

[0061] It should be noted that the second preset value can be the value entered by the designer into the integrated stove control system before the integrated stove leaves the factory, or it can be the value entered by the user into the integrated stove control system according to the actual use environment. This implementation does not limit the second preset value, as long as it can meet the user's requirements for ambient air.

[0062] Specifically, the external air quality detector 5 detects the external air quality index outside the installation space 100 and transmits it to the control system of the integrated stove. The control system compares the external air quality index with a second preset value. When the external air quality index is greater than or equal to the second preset value, the range hood 200 is activated to purify the air in the open space of the kitchen.

[0063] The following example, using two installation spaces of 100 cubic meters each, details the specific steps of this kitchen air purification method. Figures 1-3 As shown, there are two installation spaces 100, namely a first installation space 101 and a second installation space 102; there are two branch pipes 22, namely a first branch pipe and a second branch pipe, the first branch pipe connecting the first installation space 101 and the main pipe 21, and the second branch pipe connecting the second installation space 102 and the main pipe 21; there are two branch switch valves 3, namely a first valve and a second valve, the first valve being located between the first branch pipe and the main pipe, and the second valve being located between the second branch pipe and the main pipe; there are two branch air quality detectors 1, namely a first branch air quality detector located in the first installation space 101 and a second branch air quality detector located in the second installation space 102, the first branch air quality detector being used to detect the first internal air quality index in the first installation space 101, and the second branch air quality detector being used to detect the second internal air quality index in the second installation space 102.

[0064] Specifically, when the first internal air quality index is greater than or equal to the first preset value, the second internal air quality index is less than the first preset value, and the external air quality index is less than the second preset value, the control system controls the first valve and the main switch valve 4 to open, the second valve to close, and starts the range hood 200.

[0065] When the first internal air quality index is less than the first preset value, the second internal air quality index is greater than or equal to the first preset value, and the external air quality index is less than the second preset value, the control system controls the second valve and the main switch valve 4 to open, the first valve to close, and starts the range hood 200.

[0066] When the first internal air quality index is less than the first preset value, the second internal air quality index is less than the first preset value, and the external air quality index is greater than or equal to the second preset value, the control system controls the first valve, the second valve, and the main switch valve 4 to close, and starts the range hood 200.

[0067] When the first internal air quality index is greater than or equal to the first preset value, the second internal air quality index is greater than or equal to the first preset value, and the external air quality index is less than the second preset value, the control system controls the first valve, the second valve, and the main switch valve 4 to open and starts the range hood 200.

[0068] When the first internal air quality index is less than the first preset value, the second internal air quality index is greater than or equal to the first preset value, and the external air quality index is greater than or equal to the second preset value, the control system controls the second valve and the main switch valve 4 to open, the first valve to close, and starts the range hood 200.

[0069] When the first internal air quality index is greater than or equal to the first preset value, the second internal air quality index is less than the first preset value, and the external air quality index is greater than or equal to the second preset value, the control system controls the first valve and the main switch valve 4 to open, the second valve to close, and starts the range hood 200.

[0070] When the first internal air quality index is greater than or equal to the first preset value, the second internal air quality index is greater than or equal to the first preset value, and the external air quality index is greater than or equal to the second preset value, the control system controls the first valve, the second valve and the main switch valve 4 to open and starts the range hood 200.

[0071] The kitchen air purification method provided in this embodiment can not only remove the poor-quality air in the open space of the kitchen, but also remove the poor-quality air in the installation space 100 of the functional components, thereby improving the comfort and safety of kitchen use and providing a better user experience.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
