Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning sterilization device and an air conditioner. Background Art

[0002] As people's living standards improve, their requirements for living environments are getting higher and higher, not only limited to temperature regulation, but also including air cleanliness, humidity control and other aspects. Especially with the prevalence of various infectious diseases, users are particularly concerned about whether home appliances have sterilization functions. Traditional air-conditioning systems can often only achieve basic cooling and heating adjustment functions, and are powerless when faced with microbial contamination such as bacteria and viruses. In order to improve user experience and meet market demand, ultraviolet LED lamps or UVC sterilization devices are installed inside the air conditioner to sterilize and purify the air entering the air-conditioning cavity, ensure the safety of air-conditioning blow-out control, and ensure the quality of indoor air.

[0003] In the prior art, the sterilization devices inside traditional air conditioners are located in various positions. Some are installed inside the air inlet and outlet, and some are installed on the inner wall of the air circulation cavity formed by the volute and the volute cover. When the user turns on the sterilization function, the air blown out is sterilized and inhibited. In the non-sterilization state, the sterilization device is in an inactive state. For the sterilization device installed inside the air inlet and outlet, the sterilization device sterilizes and inactivates the indoor air only when it flows through the air inlet and outlet of the air conditioner. Due to the limited sterilization time, the sterilization is not thorough; for the sterilization device installed on the inner wall of the air circulation cavity formed by the volute and the volute cover, the indoor air is in a sterilization state after entering the air duct component from the air inlet until the indoor air is blown out from the air outlet. The sterilization is sufficient, but the sterilization device is installed in the cavity of the air duct component, which reduces the space in the cavity of the air duct component, and reduces the air volume blown out by the air conditioner in the working state, resulting in a poor user experience.

[0004] Since the air-conditioning sterilization device in the prior art has technical problems such as limited sterilization area, resulting in incomplete sterilization, the present invention studies and designs an air-conditioning sterilization device and an air conditioner. Summary of the invention

It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0043] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings.

[0046] like Figure 1-8 As shown, the present invention provides an air conditioning sterilization device, which includes:

[0047] A sterilization component 1 and an air duct 2, wherein the sterilization component 1 is arranged in the air duct 2, and in the sterilization mode, the sterilization component 1 can be unfolded to increase the contact area with the airflow in the air duct 2, and the airflow is sterilized when passing through the sterilization component 1; in the non-sterilization mode, the sterilization component 1 can be folded to reduce the contact area with the airflow in the air duct 2.

[0048] The present invention provides a sterilization component that can be moved and expanded inside the air duct of the air conditioner, and the sterilization component can also be folded. In the sterilization mode, the sterilization component can be expanded by movement, thereby increasing the contact area with the airflow, improving the sterilization effect on the airflow and making the sterilization more thorough. In the non-sterilization mode, the sterilization component can be folded to reduce the contact area between the airflow and the sterilization component, thereby avoiding a large resistance to the airflow, reducing the power consumption of the air conditioner and improving the energy efficiency of the air conditioner.

[0049] In some embodiments,

[0050] The sterilization component 1 includes a rotating shaft 3 and a UVC component 4, wherein the UVC component 4 is sleeved on the rotating shaft 3, and there are at least two UVC components 4. Along the axial direction of the rotating shaft 3, at least two of the UVC components 4 are assembled to different axial positions on the rotating shaft 3, and the rotating shaft 3 can drive the UVC components 4 to move when it is driven to rotate; when the rotating shaft 3 rotates in a first direction, at least two of the UVC components 4 are driven by the rotating shaft 3 to move to positions that are not opposite in the axial direction, so that the sterilization component 1 is unfolded; when the rotating shaft 3 rotates in a second direction, at least two of the UVC components 4 are driven by the rotating shaft 3 to move to positions that are opposite in the axial direction, so that the sterilization component 1 is folded, wherein the first direction and the second direction are different directions.

[0051] The present invention also preferably adopts a structural form in which the sterilization component includes a rotating shaft and a UVC component. The UVC component is sleeved on the outer circumference of the rotating shaft and can follow the rotation of the rotating shaft in different directions, thereby realizing the expansion or folding of the sterilization component. The structure is simple, the operation is convenient, the sterilization degree can be improved, and the system power consumption can be reduced.

[0052] In some embodiments,

[0053] A card slot 5 is provided on the outer circumferential wall of the rotating shaft 3. The UVC component 4 is a plate-like structure, and a mounting hole 6 is provided at one end of the plate-like structure along the axial direction. The UVC component 4 can be mounted on the outer circumference of the rotating shaft 3 through the mounting hole 6. A protrusion 7 is provided on the inner wall of the mounting hole 6 protruding toward the mounting hole 6. The protrusion 7 is clamped in the card slot 5. The card slot 5 has a preset width in the circumferential direction. When the rotating shaft 3 rotates, the protrusion 7 can move from one circumferential end of the card slot 5 to the other circumferential end relative to the rotating shaft 3.

[0054] The present invention further arranges a plurality of slots with different lengths in the circumferential direction on the rotating shaft at intervals along the axial direction, and cooperates with the mounting hole of the UVC component and the structure of the protrusion, so that the protrusion can be clamped in the slot. Since the lengths of the slots in the circumferential direction are different, when rotating along the first direction, the plurality of UVC components can be driven to rotate and be fixed to different circumferential positions respectively, thereby realizing the expansion and sterilization of the UVC components, and when rotating along the second direction, the plurality of UVC components can be driven to rotate and be fixed to the same circumferential position (relative in the axial direction) respectively, thereby realizing the folding of the UVC components, so as to reduce the obstruction to the airflow in the non-sterilization mode, reduce power consumption, and improve the energy efficiency of the system.

[0055] like Figure 6-7 As shown in the figure, it is a schematic diagram of the structure of the rotating shaft of the sterilization device. There are corresponding grooves on the rotating shaft. Figure 8 The figure shows the schematic diagram of the structure of the UVC sterilization component of the sterilization device. Each groove is matched with a single UVC sterilization component. The groove on the rotating shaft limits the rotation angle of the UVC sterilization component. Driven by the motor, the rotating shaft rotates. As the rotating shaft is driven, the UVC sterilization component will be driven to rotate by the rotating shaft. When it rotates to the other side of the groove, the UVC sterilization component is restricted, so that its position is fixed, which is used to unfold the UVC sterilization component.

[0056] In some embodiments,

[0057] There are a plurality of the card slots 5 arranged at intervals in the axial direction of the rotating shaft 3 , there are also a plurality of the UVC components 4 , and the UVC components 4 are arranged one-to-one with the card slots 5 , and each protrusion 7 on the UVC component 4 is clamped in a card slot 5 .

[0058] This is a further preferred structural form of the card slot and UVC component of the present invention. Through multiple card slots arranged at intervals along the axial direction, they can be arranged one-to-one with each UVC component, so that the protrusion of each UVC component is clamped in a card slot, so that the rotation of the rotating shaft drives the protrusion and then drives the UVC component to rotate, so that multiple UVC components in the axial direction are rotated to different circumferential positions to complete the expansion, and multiple UVC components in the axial direction are rotated to the same circumferential position to achieve the effect of folding.

[0059] In some embodiments,

[0060] One circumferential end of the plurality of slots 5 are relatively arranged in the axial direction of the rotating shaft 3, and the other circumferential ends of the plurality of slots 5 are not relatively arranged in the axial direction of the rotating shaft 3, and the circumferential lengths of the plurality of slots 5 along the axial direction of the rotating shaft 3 increase or decrease successively.

[0061] The present invention arranges one circumferential end of the plurality of card slots relatively to each other in the axial direction, and can drive the UVC component to move to be relatively to each other in the axial direction through this end, thereby forming a retracted effect, which is suitable for a non-sterilization mode; the other circumferential ends of the plurality of card slots are not relatively to each other in the axial direction, and can drive the UVC component to move to be not relatively to each other in the axial direction through this end, thereby forming an expanded effect, which is suitable for a sterilization mode; the circumferential lengths of the plurality of card slots 5 increase or decrease in sequence along the axial direction, and can form a maximum expanded area in the circumferential direction in the axial direction, thereby increasing the sterilization contact area with the airflow, and making the sterilization more thorough.

[0062] The present invention solves the problem of incomplete sterilization caused by the fixed position of the sterilization device in the current air conditioner. The sterilization device is unfolded during sterilization to increase the sterilization area, and is retracted when sterilization is not required; 2. The specific unfolding method is Figure 3-8 The structure has multiple UVC components arranged in the rotating shaft and axial direction, and the circumferential opening range of the card slot is different, so that it can be driven at different times, thereby expanding to different angular positions to achieve expansion.

[0063] In some embodiments,

[0064] The circumferential one end of the multiple card slots 5 rotates along the second direction to drive the multiple protrusions 7 to rotate. When the circumferential one end of the multiple card slots 5 rotates to the first preset position, the multiple UVC components 4 are driven to be axially opposite to each other to retract the sterilization components; the circumferential other end of the multiple card slots 5 rotates along the first direction to drive the multiple protrusions 7 to rotate. When the circumferential other end of the multiple card slots 5 rotates to the second preset position, the multiple UVC components 4 are driven to be not opposite to each other in the axial direction to unfold the sterilization component 1.

[0065] The present invention drives the protrusion to rotate by using one circumferential end of the multiple card slots. When the one circumferential end of the card slot moves to a first preset position, the multiple UVCs move to be axially opposite to each other, so that the sterilization component is retracted, which is suitable for a non-sterilization mode. The multiple card slots drive the protrusion to rotate by using the other circumferential end of the multiple card slots. When the other circumferential end of the card slot moves to a second preset position, the multiple UVCs move to be not axially opposite to each other, so that the sterilization component is unfolded, which is suitable for a sterilization mode.

[0066] Figure 8 This is a top view of a UVC component. The circle on the left is a hollow mounting hole, which is sleeved on the outer circumference of the rotating shaft. The vertical strip structure is a protruding protrusion, which is clamped on the Figure 6-7 The rotating shaft is rotated (in the slot of the rotating shaft) from the closed position (the position where multiple UVC axes are opposite to each other), and the rotating shaft rotates (along Figure 7During the process of rotating the UVC component at the bottom (counterclockwise), the UVC component at the bottom is driven to rotate first, and then the components upward are driven to rotate in sequence.

[0067] Preferably, the UVC component and the rotating shaft are made into one piece, and preferably the two are integrally formed.

[0068] In some embodiments,

[0069] Along the axial direction of the rotating shaft 3 , the circumferential angles occupied by the plurality of clamping grooves 5 in the circumferential direction of the rotating shaft 3 are 180°, 165°, 120°, 90°, 60° and 30° respectively.

[0070] This is the preferred arrangement of the multiple card slots of the present invention, that is, the circumferential angles of the multiple card slots in the axial direction are 180°, 165°, 120°, 90°, 60° and 30° respectively, and the rotation of the rotating shaft can be used to drive the protrusion and then drive the UVC component to rotate, so that the multiple UVC components in the axial direction can be rotated to different circumferential positions to complete the expansion, and the multiple UVC components in the axial direction can be rotated to the same circumferential position to achieve the effect of folding.

[0071] In some embodiments,

[0072] It also includes a steering plate 8, which has a space for accommodating the rotating shaft 3. The steering plate 8 is provided with an assembly hole for accommodating the insertion of the rotating shaft 3 at a position opposite to the space, so that both axial ends of the rotating shaft 3 are inserted into the assembly hole. The steering plate 8 can also limit the further rotation of the multiple UVC components 4 when they are rotated to the folded position.

[0073] The present invention can also be used to set a rotating shaft through the setting of a steering plate, and the steering plate can limit the movement of the UVC component, not only limiting the further movement of the folded position, but also limiting the further rotation of the unfolded position.

[0074] The air conditioner controllable sterilization device provided by the present invention has a large plane of the steering plate in a closed state and an outer surface of the air duct component in a coincident state, and six UVC sterilization devices are aligned in the axial direction and are in a parallel state with the outer surface of the air duct component, and large and small gears and a DC motor are fixed on the other side of the steering plate. In the open state, the steering plate rotates 90 degrees around its axis, and then under the action of the DC motor and the large and small gears, the UVC sterilization device unfolds around the bearing at a certain angle, similar to the opening of a fan, and then the UVC sterilization device starts to work.

[0075] In some embodiments,

[0076] It also includes a motor 9, a first gear 10 and a second gear 11. The motor 9 is connected to the first gear 10 to drive the first gear 10 to rotate. The first gear 10 and the second gear 11 form a tooth engagement. The rotation of the first gear 10 drives the second gear 11 to rotate. The gear shaft of the second gear 11 can drive the rotating shaft 3 to rotate.

[0077] The present invention can form the effect of sequential driving and transmission through the structure of the motor, the first and second gears, and achieve the effect and purpose of driving the rotating shaft to rotate.

[0078] like Figure 3 As shown, the controllable sterilization device of the present invention is composed of a steering plate, a UVC sterilization component, a large gear (first gear), a small gear (second gear) and a DC motor. The function of the steering plate is to control the opening and closing of the sterilization device to achieve different states under different requirements. The UVC sterilization device sterilizes and inhibits bacteria in the air to ensure the air quality in the air. The large gear and the small gear are used in conjunction with the DC motor to ensure the opening and closing of the UVC sterilization device.

[0079] The controllable sterilization component is fixed to the outer side of the volute and the volute cover of the air duct component through a moving part (rotating shaft 3). In the space cavity formed by the evaporator, the volute and the volute cover of the air duct component, the moving part can rotate the controllable sterilization device around its axis in the space formed by the air duct component and the evaporator component under the action of the driving device, and control the expansion degree of the controllable sterilization device according to different states to realize the opening and closing of the controllable sterilization device. The driving device of the controllable sterilization device of the air conditioner provided by the present invention is used to move and rotate the controllable sterilization device to a corresponding position, control the expansion and closing of the sterilization device at the corresponding position, thereby realizing the opening and closing of sterilization.

[0080] In some embodiments,

[0081] The gear shaft of the second gear 11 is connected to the rotating shaft 3 via an adapter 12, so that the axis of the gear shaft of the second gear 11 intersects with the axis of the rotating shaft 3 at 0 to 180 degrees; the second gear 11 is a fan-shaped structure.

[0082] This is a further preferred structural form of the present invention. Through the provision of the adapter, the transmission of the shaft rotation can be easily achieved, and the transmission effect of the shaft rotation can be achieved even if they are not in the same plane or on the same straight line.

[0083] The present invention also provides an air conditioner, which includes the aforementioned air conditioner sterilization device.

[0084] The air conditioner of the present invention is provided with a controllable sterilization device between the air conditioner volute and the evaporator. The position and working state of the sterilization device can be adjusted when the air is inletted from the top and outletted from the bottom, outletted from the top and inletted from the bottom, or outletted from the top and bottom at the same time, so as to ensure that the virus and bacteria are completely inactivated during sterilization and the air volume is maximized when not sterilizing.

[0085] The present invention solves the following technical problems:

[0086] A component device with reversible up and down air outlet and a controllable sterilization device is provided to solve the problems of incomplete sterilization, insufficient air volume, high noise and inability to be commercialized in current air conditioners due to the fixed position of the sterilization device.

[0087] Beneficial effects:

[0088] By adopting a reversible air supply and return component device with a controllable sterilization device, the air conditioner can achieve different air inlet and outlet modes under different working conditions and temperatures. Under the same working condition and temperature, the air conditioner can achieve a large air volume inlet and outlet mode.

[0089] The user turns on the sterilization function, and in cooling mode, the controllable sterilization device and the motion mechanism rotate to the corresponding position one, the downwind outlet opens and switches to the air inlet, and the air conditioner switches to the downwind inlet and upwind outlet mode; in heating mode, the controllable sterilization device and the motion mechanism rotate to the corresponding position two, the upwind outlet opens and switches to the air inlet, and the air conditioner switches to the upwind inlet and downwind outlet mode, which increases the time that bacteria and viruses contact the sterilization device and improves the sterilization rate; in the non-sterilization state, the controllable sterilization device and the motion mechanism rotate to the corresponding position three, and the air conditioner maximizes the air volume when cooling or heating.

[0090] The present invention adopts a reversible air supply and return component device with a controllable sterilization device, so that the air conditioner can realize different air inlet and outlet modes under different working conditions and different temperatures. Under the same working condition and the same temperature, the air conditioner can realize a large air volume air inlet and outlet mode.

[0091] The air conditioner of the present invention preferably has an upper air guide port on the side wall of the upper air outlet channel, and an upper baffle plate on the upper air guide port; and a lower air guide port on the side wall of the lower air outlet channel, and a lower baffle plate on the lower air guide port. When the upper baffle plate is opened, the upper air guide port is controlled to be opened, the lower baffle plate is closed, the lower air guide port is controlled to be closed, the lower air outlet and the lower air outlet channel are in a connected state, the upper air outlet serves as the air inlet, and the lower air outlet serves as the air outlet channel; when the lower baffle plate is opened, the lower air guide port is controlled to be opened, the upper baffle plate is closed, the upper air guide port is controlled to be closed, the upper air outlet and the upper air outlet channel are in a connected state, the lower air outlet serves as the air inlet, and the upper air outlet serves as the air outlet channel.
