Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a range hood and a sterilization component thereof. Background Art

[0002] A range hood, also known as a smoke extractor, is a kitchen appliance that purifies the kitchen environment. Installed above the kitchen stove, it quickly extracts waste from stove combustion and harmful cooking fumes, exhausting them outdoors. It also condenses and collects the fumes, reducing pollution, purifying the air, and providing safety features like anti-toxicity and explosion protection.

[0003] The range hoods in the related technology, whether they are ceiling-type range hoods or close-type range hoods, etc., are generally of external exhaust type and do not have sterilization and purification functions. After long-term use, the smoke hood, bellows, etc. inside the range hood are prone to accumulate oil and dirt, and cause the growth of bacteria and microorganisms or the generation of odors, thereby adversely affecting the kitchen environment and even the health of users.

[0004] Some range hoods with sterilization functions are now available on the market. These typically utilize ultraviolet (UV) lamps installed within the hood body to disinfect and sterilize. The UV beam breaks down oxygen molecules in the air, generating free oxygen. This free oxygen then combines with oxygen molecules to form ozone, a powerful oxidizing agent that removes oil smoke and odors. However, over time, oil stains inside the range hood can easily come into contact with and adhere to the UV lamp's outer wall, affecting its sterilization effectiveness and lifespan. Summary of the Invention

[0005] The first technical problem solved by the present application is to provide a sterilization component of a range hood, which can effectively prevent oil stains from adhering to the surface of the sterilization component, thereby improving the sterilization effect and increasing the service life.

[0006] The second technical problem solved by the present application is to provide a range hood that can effectively prevent oil stains from adhering to the surface of the sterilization component, thereby improving the sterilization effect and increasing the service life.

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0008] A sterilization component for a range hood, comprising:

[0009] A housing, wherein an exhaust port communicating with a bellows is formed at the bottom of the housing, and a first air inlet portion and a second air inlet portion are further provided on the side of the housing, respectively communicating with the interior of the housing, the first air inlet portion being used to communicate with the bellows of the range hood, and the second air inlet portion being used to communicate with the outside; and

[0010] A sterilization component is arranged inside the shell and opposite to the exhaust port, the air outlet position of the first air inlet and the air outlet position of the second air inlet are both located between the sterilization component and the exhaust port, and along the direction Z pointing from the sterilization component to the exhaust port, the distance S1 between the sterilization component and the exhaust port is respectively greater than the distance S2 between the air outlet position of the first air inlet and the exhaust port and the distance S3 between the air outlet position of the second air inlet and the exhaust port, and S3>S2.

[0011] The sterilization component of the range hood described in this application has the following beneficial effects compared with the background art:

[0012] The sterilization component of the above-mentioned range hood utilizes the principle of internal air pressure. During the rotation of the air cabinet of the range hood, the smoke is discharged outward while the smoke will simultaneously enter the interior of the shell through the first air inlet and flow back to the interior of the bellows from the exhaust port. During the flow, pressure is generated inside the shell, thereby bringing in fresh air through the second air inlet on the side of the shell. Because the sterilization component is positioned within the housing and opposite the exhaust port, the outlets of the first and second air inlets are both located between the sterilization component and the exhaust port. Along the direction Z of the sterilization component pointing toward the exhaust port, the distance S1 between the sterilization component and the exhaust port is greater than the distance S2 between the outlet of the first and second air inlets, and the distance S3 between the outlet of the second and second air inlets. This allows fresh air to pass through the side of the sterilization component facing the exhaust port and flow back into the bellows through the exhaust port. S3 > S2, thus forming a protective air curtain between the oil smoke and the sterilization component, preventing oil smoke from contaminating the sterilization component. This extends the service life of the sterilization component and protects the sterilization effect from being affected by oil contamination. Furthermore, the ultraviolet light generated by the sterilization component during operation is emitted through the exhaust port, sterilizing bacteria inside the bellows and preventing them from spreading into the kitchen and affecting consumer health.

[0013] In one embodiment, the sterilization component of the range hood is installed on the top of the bellows, and the first air inlet is used to communicate with the smoke exhaust part of the bellows.

[0014] In one embodiment, there are at least two second air inlets, which are arranged in sequence and spaced apart along the circumference of the housing.

[0015] In one embodiment, the number of the second air inlet portions is two and the second air inlet portions are symmetrically arranged on opposite sides of the housing; the first air inlet portion is located in the area between the two second air inlet portions.

[0016] In one embodiment, the shell forms a chamber, and the shell includes a first side plate, a second side plate and a third side plate connected in sequence, and the first side plate is arranged opposite to the third side plate; the first air inlet portion penetrates the second side plate along the first direction X and is connected to the chamber; the second side plate is also formed with an air inlet channel extending along the first direction X and connected to the chamber; one of the second air inlets penetrates the first side plate and the second side plate in sequence along the second direction Y and is connected to the air inlet channel; the other second air inlet portion penetrates the third side plate and the second side plate in sequence along the second direction Y and is connected to the air inlet channel.

[0017] In one embodiment, the sterilization component of the range hood further includes a light-transmitting component disposed inside the shell, and the light-transmitting component is located on the side of the sterilization component facing the exhaust port, so that the oil smoke and air entering the shell are completely isolated from the sterilization component.

[0018] In one embodiment, the housing includes an openable cover; the light-transmitting element and the sterilization component are both detachably mounted inside the housing.

[0019] In one embodiment, the outer wall surface of the shell is a first flange circumferentially arranged around the first air inlet portion, and the sterilization component of the range hood also includes a connecting pipe, one end of the connecting pipe is plugged into the first flange, and the other end is connected to the smoke exhaust portion; the sterilization component of the range hood also includes an air inlet nozzle arranged to be connected to the second air inlet portion and located outside the shell; the outer wall surface of the shell is a second flange circumferentially arranged around the exhaust port, and the second flange is used to be inserted into the docking port on the top of the bellows.

[0020] In one embodiment, the housing is configured as a metal shell; the sterilization component includes a light panel and / or a light tube that can emit ultraviolet rays.

[0021] The second technical problem mentioned above is solved by the following technical solution:

[0022] A range hood includes the sterilization component of the range hood and a bellows. The sterilization component is installed on the top of the bellows. The bellows is provided with a smoke exhaust part. The first air inlet is connected to the smoke exhaust part of the bellows.

[0023] The range hood described in this application / application has the following beneficial effects compared with the background art:

[0024] The above-mentioned range hood utilizes the principle of internal air pressure. During the rotation of the range hood's wind cabinet, smoke is simultaneously exhausted outward and simultaneously enters the interior of the housing through the first air inlet, then flows back into the bellows through the exhaust port. During this flow, pressure is generated within the housing, thereby drawing fresh air into the second air inlet on the side of the housing. Because the sterilization component is disposed within the housing and opposite the exhaust port, the outlets of the first and second air inlets are both located between the sterilization component and the exhaust port. Along the direction Z of the sterilization component toward the exhaust port, the distance S1 between the sterilization component and the exhaust port is greater than the distance S2 between the outlet of the first air inlet and the exhaust port, and the distance S3 between the outlet of the second air inlet and the exhaust port, respectively. This allows the fresh air to pass through the side of the sterilization component facing the exhaust port and flow back into the bellows through the exhaust port. S3 is greater than S2, thereby forming a protective air curtain between the oil smoke and the sterilization component, preventing oil smoke from contaminating the sterilization component. This, in turn, extends the service life of the sterilization component and ensures that the sterilization effect is not affected by oil contamination. In addition, the ultraviolet light generated when the sterilization component is working is emitted through the exhaust port, which has a sterilization effect and can eliminate the bacteria inside the bellows, preventing the bacteria from spreading into the kitchen and affecting the health of consumers.

[0035] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0036] See Figure 1 、 Figures 4 to 6 , Figure 1 A structural diagram of a sterilization component of a range hood according to an embodiment of the present application is shown. Figure 4 Shown Figure 1 Cross-sectional structural diagram at AA. Figure 5 The structure diagram of a range hood according to an embodiment of the present application is shown. Figure 6 Shown Figure 5An enlarged structural diagram at point B. An embodiment of the present application provides a sterilization component 10 for a range hood, which is specifically installed on the top of a bellows 20. The sterilization component 10 for the range hood includes: a shell 11 and a sterilization component 12. An exhaust port 111 communicating with the bellows 20 is formed at the bottom of the shell 11, and a first air inlet 112 and a second air inlet 113 communicating with the interior of the shell 11 are further provided on the side of the shell 11. The first air inlet 112 is used to communicate with the bellows 20, specifically, for example, with the smoke exhaust portion 21 of the bellows 20. The second air inlet 113 is used to communicate with the outside world. The sterilization component 12 is arranged inside the shell 11 and is opposite to the exhaust port 111. The outlet position of the first air inlet 112 and the outlet position of the second air inlet 113 are both located between the sterilization component 12 and the exhaust port 111. In the direction Z pointing from the sterilization component 12 to the exhaust port 111, the distance S1 between the sterilization component 12 and the exhaust port 111 is greater than the distance S2 between the outlet position of the first air inlet 112 and the exhaust port 111, and the distance S3 between the outlet position of the second air inlet 113 and the exhaust port 111. S3>S2, that is, in the direction Z, the outlet position of the second air inlet 113 is located between the outlet position of the first air inlet 112 and the sterilization component 12, the outlet position of the second air inlet 113 is close to the sterilization component, and the outlet position of the first air inlet 112 is far away from the sterilization component.

[0037] It should be noted that, in order to achieve communication with the exhaust port 111 at the bottom of the housing 11, a corresponding docking port is provided on the top of the bellows 20. The exhaust port 111 at the bottom of the housing 11 is docked and connected with the docking port on the top of the bellows 20. This allows the smoke entering the interior of the housing 11 from the outlet of the first air inlet 112 and the fresh air entering the interior of the housing 11 from the outlet of the second air inlet 113 to flow back into the interior of the bellows 20 in sequence through the exhaust port 111 and the docking port. In addition, the ultraviolet light from the sterilization component 12 can be emitted into the interior of the bellows 20 in sequence through the exhaust port 111 and the docking port. In addition, the smoke exhaust portion 21 includes, but is not limited to, being provided on the side wall of the check valve, on the wall of the smoke exhaust pipe, or at any other location according to actual needs.

[0038] The above-mentioned sterilization component 10 of the range hood utilizes the principle of internal air pressure. During the rotation of the wind cabinet of the range hood, while exhausting the smoke outward, the smoke will also enter the interior of the shell 11 through the first air inlet 112 at the same time, and flow back to the interior of the bellows 20 from the exhaust port 111. During the flow process, pressure is generated inside the shell 11, thereby bringing in fresh air from the second air inlet 113 on the side of the shell 11. Since the sterilization component 12 is arranged inside the shell 11 and is opposite to the exhaust port 111, the air outlet position of the first air inlet 112 and the air outlet position of the second air inlet 113 are both located between the sterilization component 12 and the exhaust port 111. Along the direction Z pointing from the sterilization component 12 to the exhaust port 111, the distance S1 between the sterilization component 12 and the exhaust port 111 is respectively greater than the distance S2 between the air outlet position of the first air inlet 112 and the exhaust port 111 and the distance S3 between the air outlet position of the second air inlet 113 and the exhaust port 111. In this way, the fresh air brought in passes through the side of the sterilization component 12 facing the exhaust port 111 and flows back to the inside of the bellows 20 through the exhaust port 111, S3>S2, so that a protective air curtain can be formed between the oil smoke and the sterilization component 12 to prevent the oil smoke from contaminating the sterilization component 12, thereby extending the service life of the sterilization component 12 and ensuring that the sterilization effect is not affected by oil pollution. In addition, the ultraviolet light generated by the sterilization component 12 when working is emitted through the exhaust port 111, which has a sterilization effect and can eliminate bacteria inside the bellows 20, preventing bacteria from spreading into the kitchen and affecting consumers' health.

[0039] In some embodiments, the exhaust port 111 includes, but is not limited to, various regular shapes such as an elliptical port, an oblong port, a circular port, a square port, a triangular port, and other irregular shapes, and can be flexibly adjusted and configured according to actual needs. Specifically, to allow the ultraviolet light emitted by the sterilization component 12 to better penetrate the interior of the bellows 20, the projection of the opening area of the exhaust port 111 along the direction Z pointing from the sterilization component 12 to the exhaust port 111 can, for example, completely cover the sterilization component 12. Of course, the projection of the opening area of the exhaust port 111 along the direction Z pointing from the sterilization component 12 to the exhaust port 111 can also partially overlap with the sterilization component 12.

[0040] See also Figure 1 and Figure 2 In one embodiment, at least two second air inlets 113 are provided and spaced apart along the circumference of the housing 11. As the number of second air inlets 113 increases, fresh air can more easily enter the housing 11 and form a protective air curtain.

[0041] The number of the second air inlet parts 113 includes but is not limited to two, three, four or more.

[0042] See also Figure 1 and Figure 2In one embodiment, two second air inlets 113 are provided and symmetrically arranged on opposite sides of the housing 11. The first air inlet 112 is located in the area between the two second air inlets 113. As the smoke from the smoke exhaust 21 enters the housing 11 through the first air inlet 112, pressure is generated within the housing 11, causing fresh air to enter the two second air inlets 113 on opposite sides of the first air inlet 112 simultaneously, thereby forming a protective air curtain.

[0043] In some embodiments, the cross-sectional profile of the outer shell 11 in a direction perpendicular to its bottom surface includes but is not limited to a rectangle, a circle, an ellipse, and the like. Specifically, taking the cross-sectional profile as a rectangle as an example, the outer shell 11 is correspondingly a rectangular parallelepiped shell. The outer shell 11 includes four side panels connected in sequence. The two second air inlets 113 are respectively arranged on two oppositely arranged side panels, and the first air inlet 112 is arranged on any one of the remaining two side panels, and is located, for example, in the middle portion. In this way, when the smoke from the smoke exhaust section 21 enters the interior of the outer shell 11 through the first air inlet 112, and specifically, for example, the smoke enters from the middle portion of the side panel, thereby forming a pressure of equal size on its left and right sides, and thereby making the amount of fresh air entering the two second air inlets 113 equal.

[0044] It should be noted that the first air inlet 112 and the second air inlet 113 are independently configured, and can be configured as a straight channel or a curved channel. They can be flexibly adjusted and configured according to actual needs and are not limited here.

[0045] See also Figures 1 to 4In a specific embodiment, the housing 11 is formed with a chamber 114, and the housing 11 includes a first side plate 115, a second side plate 116, and a third side plate 117 connected in sequence. The first side plate 115 and the third side plate 117 are arranged opposite to each other. Of course, the housing 11 further includes, for example, a fourth side plate 118 arranged opposite to the second side plate 116. The first side plate 115, the second side plate 116, the third side plate 117, and the fourth side plate 118 together form the side wall of the housing 11. The first air inlet portion 112 passes through the second side plate 116 along the first direction X and is in communication with the chamber 114. In addition, an air inlet channel 119 extending along the first direction X and in communication with the chamber 114 is also formed on the second side plate 116. One of the second air inlets 113 sequentially penetrates the first side panel 115 and the second side panel 116 along the second direction Y and communicates with the air inlet channel 119. The other second air inlet 113 sequentially penetrates the third side panel 117 and the second side panel 116 along the second direction Y and communicates with the air inlet channel 119. In this way, after the smoke from the smoke exhaust section 21 enters the chamber 114 along the first direction X through the first air inlet 112, a negative pressure is formed inside the chamber 114, causing fresh air from outside the housing 11 to flow in through the two second air inlets 113 in the second direction Y and into the chamber 114 through the air inlet channel 119 in the first direction X. This forms an air curtain in the direction Z along the sterilization component 12 pointing toward the exhaust port 111. Ultimately, the smoke inside the chamber 114 and the fresh air enter the bellows through the exhaust port 111 together. Since S3>S2, the sterilization assembly can effectively prevent smoke from contaminating the sterilization component.

[0046] It should be noted that the first direction X can be perpendicular to the direction Z along the sterilization component 12 toward the exhaust port 111, or can be arranged at an acute angle or an obtuse angle thereto. This can be flexibly adjusted and set based on actual needs and is not limited here. Similarly, the second direction Y can be perpendicular to the direction Z along the sterilization component 12 toward the exhaust port 111, or can be arranged at an acute angle or an obtuse angle thereto. This can be flexibly adjusted and set based on actual needs and is not limited here.

[0047] See also Figures 1 to 4In one embodiment, the sterilization component 10 of the range hood further includes a light-transmitting member 13 disposed inside the housing 11. The light-transmitting member 13 is located on the side of the sterilization component 12 facing the exhaust port 111, so that the oil smoke and air entering the interior of the housing 11 are completely isolated from the sterilization component 12. In this way, on the one hand, the light-transmitting member 13 plays a role in isolating the oil smoke, which can effectively prevent the oil smoke from contacting the sterilization component 12 and causing damage to the sterilization component 12; on the other hand, the fresh air brought into the interior of the housing 11 flows through the side of the light-transmitting member 13 facing the exhaust port 111 to form a protective wind curtain, which can prevent the oil smoke from contacting and contaminating the light-transmitting member 13, so that the sterilization effect is not affected by oil stains; in addition, the ultraviolet light emitted by the sterilization component 12 can normally pass through the light-transmitting member 13, the exhaust port 111 and the docking port and enter the interior of the bellows 20.

[0048] In some embodiments, the light-transmitting member 13 is specifically a light-transmitting sheet or a light-transmitting plate. In addition, the light-transmitting member 13 includes but is not limited to using quartz glass with high light transmittance so that the output of ultraviolet rays is not weakened.

[0049] In one embodiment, the housing 11 includes an openable cover, namely the fourth side panel 118 in the above-mentioned embodiment. In addition, the light-transmitting member 13 and the sterilizing component 12 are both detachably mounted inside the housing 11. Specifically, the light-transmitting member 13 and the sterilizing component 12 are each detachably mounted inside the housing 11 by means of, but not limited to, snap-fitting or fasteners such as pins, rivets, and screws. In this way, after the cover is opened, the assembly and disassembly operations of the light-transmitting member 13 and the sterilizing component 12 can be facilitated. In this embodiment, a first snap-fitting portion 15 and a second snap-fitting portion 16 are provided inside the housing 11. The sterilizing component 12 is snap-fitted to the first snap-fitting portion 15, and the light-transmitting member 13 is snap-fitted to the second snap-fitting portion 16.

[0050] In one embodiment, the outer wall of the housing 11 includes a first flange 1191 circumferentially disposed around the first air inlet 112. The range hood sterilization assembly 10 further includes a connecting tube 14, one end of which is pluggable with the first flange 1191 and the other end of which is connected to the smoke exhaust portion 21. This facilitates the connection between the first air inlet 112 of the housing 11 and the smoke exhaust portion 21.

[0051] In one embodiment, the sterilization assembly 10 of the range hood further includes an air inlet nozzle 1192 disposed in communication with the second air inlet portion 113 and located outside the housing 11. The air inlet nozzle 1192 can extend the length of the second air inlet portion 113, thereby preventing oil smoke entering the housing 11 through the smoke exhaust portion 21 from being discharged outside the housing 11 through the second air inlet portion 113.

[0052] In one embodiment, the outer wall of the housing 11 is provided with a second flange 1193 circumferentially surrounding the exhaust port 111, and the second flange 1193 is configured to be inserted into the docking port at the top of the bellows 20. This facilitates corresponding communication between the exhaust port 111 of the housing 11 and the docking port at the top of the bellows 20.

[0053] In one embodiment, the housing 11 includes but is not limited to being a metal housing. In this way, the housing 11 has good heat dissipation performance, which can effectively reduce the heat generated during the operation of the sterilization component 12, thereby increasing the service life.

[0054] In one embodiment, the sterilization component 12 includes a light panel and / or a light tube that can emit ultraviolet light.

[0055] In one embodiment, a range hood includes the sterilization component 10 of the range hood of any of the above embodiments, and also includes a bellows 20. The sterilization component 10 is installed on the top of the bellows 20. The bellows 20 is provided with a smoke exhaust part 21. The first air inlet part 112 is connected to the smoke exhaust part 21 of the bellows 20.

[0056] The above-mentioned range hood utilizes the principle of internal air pressure. During the rotation of the wind cabinet of the range hood, while exhausting smoke outward, the smoke will also enter the interior of the shell 11 through the first air inlet 112 and flow back to the interior of the bellows 20 from the exhaust port 111. During the flow process, pressure is generated inside the shell 11, thereby bringing in fresh air from the second air inlet 113 on the side of the shell 11. Since the sterilization component 12 is arranged inside the shell 11 and is opposite to the exhaust port 111, the air outlet position of the first air inlet 112 and the air outlet position of the second air inlet 113 are both located between the sterilization component 12 and the exhaust port 111. Along the direction Z pointing from the sterilization component 12 to the exhaust port 111, the distance S1 between the sterilization component 12 and the exhaust port 111 is respectively greater than the distance S2 between the air outlet position of the first air inlet 112 and the exhaust port 111 and the distance S3 between the air outlet position of the second air inlet 113 and the exhaust port 111. In this way, the fresh air brought in passes through the side of the sterilization component 12 facing the exhaust port 111 and flows back to the inside of the bellows 20 through the exhaust port 111, S3>S2, so that a protective air curtain can be formed between the oil smoke and the sterilization component 12 to prevent the oil smoke from contaminating the sterilization component 12, thereby extending the service life of the sterilization component 12 and ensuring that the sterilization effect is not affected by oil pollution. In addition, the ultraviolet light generated by the sterilization component 12 when working is emitted through the exhaust port 111, which has a sterilization effect and can eliminate bacteria inside the bellows 20, preventing bacteria from spreading into the kitchen and affecting consumers' health.
