Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a gas purification device and a kitchen appliance. Background Art

[0002] The quality of air is of vital importance. For example, the quality of kitchen air not only affects the physical and mental health of the family, but also has a great impact on the mood of the cook. In recent years, various kitchen appliance manufacturers have been conducting research on relevant technologies for kitchen air treatment.

[0003] The existing technology generally involves installing related generating devices such as ultraviolet rays, ozone, photocatalyst, low-temperature plasma, negative ions, and bactericidal liquid inside the range hood.

[0004] For example, the Chinese invention patent with application publication number CN108253473A discloses a range hood with sterilization and deodorization functions, including a housing, a fan disposed in the housing, and a sterilization and deodorization component, etc., which sterilizes, removes odors, and purifies the interior of the range hood through ultraviolet rays, ultraviolet radiation, and ozone generated by ultraviolet radiation. For another example, the Chinese invention patent with authorization announcement number CN209540967U decomposes oil smoke through low-temperature plasma installed at the air inlet of the housing, and the ozone generated by the decomposition of oil smoke by low-temperature plasma is introduced into the kitchen space for disinfection and sterilization. This solution is theoretically feasible, but due to the characteristics of Chinese cooking with multiple oils and flavors, the ozone introduced into the kitchen from the low-temperature plasma chamber often contains oil smoke and odors that are not completely purified, and is not very practical.

[0005] Although the above method can kill and purify bacteria, odors, etc. inside the range hood to a certain extent, its effect on bacteria, viruses, odors, etc. in the air of the entire kitchen space is very limited and cannot meet people's requirements for the air quality of the entire kitchen space. Summary of the invention

[0006] The object of the present invention is to provide a gas purification device and a kitchen appliance to alleviate the technical problem of poor air quality in indoor space existing in the prior art.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] This embodiment provides a gas purification device, such as Figure 1 and Figure 3 As shown, the gas purification device includes a concentration sensor 110, a control module and a medicine releasing module 120 that releases the medicine into the air. The concentration sensor 110 is used to detect the concentration of the medicine in the air and send the medicine concentration information to the control module. The control module receives the medicine concentration information and controls the medicine release amount of the medicine releasing module 120 to make the medicine concentration in the air at a preset concentration standard.

[0045] in, Figure 1 The figure shows that the gas purification device is installed on the range hood. The form of installing the gas purification device on other main bodies can refer to the range hood.

[0046] The gas purification device provided in this embodiment includes a concentration sensor 110, a control module and a medicine release module 120. During specific operation, the concentration sensor 110 can detect the concentration of medicine in the air. When the concentration of medicine is lower than the preset concentration standard, the control module receives the information of the concentration of medicine and controls the medicine release amount of the medicine release module 120 to make the concentration of medicine in the air at the preset concentration standard, thereby achieving the purpose of disinfection, sterilization and purification of indoor air to improve the indoor air quality. In short, when the smell in the kitchen is too strong, the control module can control the medicine release module 120 to release at the maximum dose.

[0047] The resolution of the concentration sensor 110 is higher than 5 ppb, preferably 1 ppb.

[0048] like Figure 3 As shown, the medicine release module includes a medicine chamber 121 with an air inlet and an air outlet, a sealing component for sealing the air inlet and the air outlet, and a fan 122 for providing power for the flow of the medicine; the fan 122 and the sealing component are both electrically connected to the control module.

[0049] When working, the sealing component opens the air inlet and outlet, and starts the fan 122 at the same time, so that the air flow can flow from the air inlet to the air outlet, and discharge the medicine into the air from the air outlet through the medicine outlet.

[0050] The medicine chamber 121 in this embodiment is used to place the medicine package 400, and the medicine package 400 is placed in a closed space. Since the concentration of the medicine in the environment where the medicine package is located is inversely proportional to the release rate of the medicine package, when the medicine chamber 121 is sealed, the release rate of the medicine package 400 can be slowed down and the use time of the medicine package 400 can be extended.

[0051] In one embodiment of the present application, the medicine package 400 is a functional medicine package made of a nano slow-release virus-killing new material (NSK-SYSU), which can slowly release chlorine dioxide gas. The slow-release virus-killing new material (NSK-SYSU) is an existing technology in the market, and its formula components are not described in detail in this application.

[0052] The material of the drug package 400 can be selected from PTFE (PolyTetra Fluoroethylene) coated spunbond non-woven fabric. Preferably, the average pore size of the PTFE membrane of the PTFE coated spunbond non-woven fabric is 1.5 μm. Preferably, the monitoring system sets a standard range of chlorine dioxide concentration, and its MIN and MAX values ​​are set to: 10ppb, 80ppb; more preferably, they are set to: 30ppb, 60ppb, so that the indoor chlorine dioxide concentration is kept within a safe range.

[0053] It should be noted that chlorine dioxide is an efficient, broad-spectrum, safe bactericidal and preservative agent, and is the most ideal substitute for chlorine preparations. It has been widely used. Some regions have approved and recommended chlorine dioxide for disinfection, mildew prevention and food preservation in food, food processing, pharmaceuticals, hospitals, public environments, etc. The World Health Organization (WHO) and the World Food Organization (FAO) have also listed chlorine dioxide as a Class A1 safe and efficient disinfectant.

[0054] In some embodiments, Figure 4 As shown, the sealing assembly includes a first baffle 123, a second baffle 124 and a driving member 125 for driving the two to move; preferably, the driving member 125 is a linear driving member, and the driving member 125 is electrically connected to the control module.

[0055] The driving member 125 may be a linear motor or a linear push rod.

[0056] Specifically, the first baffle 123 and the second baffle 124 are both connected to the output end of the driving member 125. The driving member 125 can drive the first baffle 123 and the second baffle 124 to move synchronously, and respectively move the first baffle 123 in a direction close to or away from the air inlet, and move the second baffle 124 in a direction close to or away from the air outlet, thereby closing or opening the air inlet and the air outlet.

[0057] When working, Figure 3 or Figure 4As shown, the driving member 125 drives the first baffle 123 and the second baffle 124 to move synchronously to the right, so that the first baffle 123 opens the air inlet and the second baffle 124 opens the air outlet; conversely, the driving member 125 drives the first baffle 123 and the second baffle 124 to move synchronously to the left, so that the first baffle 123 blocks the air inlet and the second baffle 124 blocks the air outlet.

[0058] In this embodiment, the air inlet and the air outlet are opened on opposite side walls of the medicine chamber 121; the first baffle plate 123 and the second baffle plate 124 are spaced apart and arranged in parallel.

[0059] Optionally, the air inlet is a plurality of circular through holes arranged on one side wall of the medicine chamber 121, the first baffle 123 is a plate-like structure, or the first baffle 123 is also provided with a circular through hole, and the two holes are not concentrically arranged; the air outlet is a plurality of circular through holes arranged on the other side wall of the medicine chamber 121, the second baffle 124 is also a plate-like structure, or the second baffle 124 is also provided with a circular through hole, and the two holes are not concentrically arranged.

[0060] In other embodiments of the present application, a round through hole is provided on the first baffle 123, and the first baffle 123 can rotate with the center of the first baffle 123 as a point, so as to be concentric or non-concentric with the round through hole on the side wall of the medicine chamber 121, and realize the opening or closing of the air inlet. Similarly, the second baffle 124 can also realize the opening or closing of the air outlet.

[0061] In one embodiment of the present application, the control module can adjust the opening and closing degree of the first baffle 123 and the second baffle 124 according to the sensor detection signal. When it is detected that the concentration of the agent is lower than the lower limit of the standard value, the control module controls the first baffle 123 and the second baffle 124 to fully open the air inlet and the air outlet. When it is detected that the concentration of the agent is higher than the upper limit of the standard value, the control module controls the first baffle 123 and the second baffle 124 to fully close the air inlet and the air outlet. When it is detected that the concentration of the agent is within the standard value range and the concentration continues to rise, the first baffle 123 and the second baffle 124 are controlled to gradually reduce the size of the air inlet and the air outlet; otherwise, the size of the air inlet and the air outlet is increased.

[0062] like Figure 3 or Figure 4 As shown, the drug release module includes a shell, in which a partition is provided, and the partition divides the space in the shell into an air supply chamber 126, the aforementioned medicine chamber 121 and an air outlet chamber 127 in sequence; the fan 122 is arranged in the air supply chamber 126, and air can be discharged from the air supply chamber 126 through the medicine chamber 121 and from the air outlet chamber 127.

[0063] The inner cavity of the shell and the related pipelines are all treated with Teflon surface. Specifically, the first baffle 123 is located in the medicine chamber 121, and the second baffle 124 is located in the air outlet chamber 127.

[0064] Optionally, the shell is made of heat-insulating material. The heat-insulating material is used to reduce or even prevent the heat generated by the external environment or kitchen appliances from being transferred to the medicine release module 120.

[0065] It should be noted that the medicine package 400 is relatively sensitive to temperature, and the service life of the medicine package 400 can be relatively extended by the heat insulation structure.

[0066] Specifically, the outer side of the shell may be covered with a heat insulating material.

[0067] Optionally, the thermal insulation material may be nano-porous thermal insulation material or nano-based thermal insulation felt.

[0068] Please continue to refer to Figure 3 or Figure 4 Through holes are provided on the side walls of the air supply chamber 126 and the air outlet chamber 127 to ensure that external air can enter the air supply chamber 126 and be discharged from the air outlet chamber 127.

[0069] like Figure 1 As shown, the purification component also includes a display screen 130, which is electrically connected to the control module and is used to display the drug concentration information, which is more intuitive.

[0070] In summary, the gas purification device can be used in home kitchens or other occasions with the above requirements.

[0071] This embodiment also provides a kitchen appliance, comprising the aforementioned gas purification device.

[0072] Furthermore, the range hood includes a range hood body 210 and a smoke collecting hood 220 connected to the range hood body 210; the agent release module 120 is arranged in the range hood body 210, and the range hood body 210 is provided with an agent outlet for discharging the agent, and the agent is discharged into the air through the agent outlet.

[0073] Optionally, the concentration sensor 110 is disposed on the front panel of the smoke hood 220, which facilitates the disassembly, assembly or replacement of the concentration sensor 110. Further, the concentration sensor 110 is installed at a position where it is not easily exposed to oil smoke, which can also improve the service life and detection accuracy of the concentration sensor 110. Of course, the concentration sensor 110 is not limited to being disposed on the front panel of the smoke hood 220, and can also be disposed at other positions on the outer wall of the range hood body 210 or the smoke hood 220.

[0074] like Figure 2As shown, the control module and the range hood controller of the range hood in this embodiment are integrated into a central processing unit 300, and the central processing unit 300 is arranged in the smoke collecting hood 220.

[0075] It should be noted that the specific configuration of the central processing unit 300 is a technology well known in the art, which is clear to those skilled in the art and will not be described in detail here.

[0076] In this embodiment, Figure 2 and Figure 3 As shown, one end of the shell is provided with an opening, and a cover plate (not shown in the drawings) is covered at the opening, and a avoidance hole for installing the cover plate is provided on the smoke machine body 210. When the medicine pack 400 needs to be replaced, the cover plate can be opened, and the medicine pack can be taken out for replacement.

[0077] In this embodiment, the medicine release module 120 is installed in the smoke machine body 210, which can make full use of the space in the smoke machine body 210. Figure 2 The position shown can facilitate the replacement of the medicine package 400.

[0078] The range hoods mentioned above may be of various types, for example, they may be ceiling-type, side-type or European-style range hoods.

[0079] For the convenience of the user, a function button for the user to manually start the medicine release module 120 may be provided on the front panel of the smoke collecting hood 220 .

[0080] Specifically, when the user sees that the chlorine dioxide concentration value on the display screen is low and the indoor odor increases, the user can manually start the agent release module 120 to increase the indoor chlorine dioxide concentration to better achieve the purpose of sterilization, disinfection and purification. In addition, the function button also includes a time knob that allows the user to freely select the release time of chlorine dioxide.

[0081] Finally, it should be noted that 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 they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
