Description

Technical Field

[0001] The present application relates to but is not limited to the field of household electrical appliance technology, and specifically refers to a sterilization device and an air conditioner. Background Art

[0002] At present, some air conditioners are equipped with sterilization devices, which produce sterilizing substances by ionizing air through high-voltage electric fields. However, condensation is easy to occur inside the air conditioner, which makes it easy for the two poles of the high-voltage electric field to be connected through condensed water, causing creepage. The occurrence of creepage not only affects the function of the sterilization device and even causes damage to the sterilization function, but also worse, causes safety accidents such as fire. Summary of the invention

[0003] The technical problem to be solved by the present application is to provide a sterilization device and an air conditioner, which are helpful to prevent the sterilization device from having creepage due to condensation, thereby helping to improve the reliability and safety of use of the sterilization device and the air conditioner.

[0005] The sterilization device provided in the embodiment of the present application is provided with an insulating barrier so that condensation must flow along the surface of the insulating barrier and bypass the insulating barrier to allow the emitter and the receiver to be connected through the condensed water and cause creepage. Therefore, the insulating barrier can increase the creepage distance between the emitter and the receiver, increase the difficulty of creepage, and thus help prevent the sterilization device from causing creepage due to condensation, thereby helping to improve the reliability and safety of the sterilization device and the air conditioner.

[0006] In addition, part of the insulating barrier is located between the emitter and the receiver, and part of it is located outside the airflow channel of the insulating mounting frame. This is beneficial to reducing the occupation of the airflow channel by the insulating barrier and seriously affecting the gas flow in the airflow channel, and is also beneficial to increasing the creepage distance between the emitter and the receiver from multiple directions (such as from the front, side, back, etc. of the sterilization device), thereby minimizing the risk of creepage due to condensation in the sterilization device and enabling the sterilization device to operate safely and stably.

[0024] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0025] The present application embodiment provides a sterilization device 2 (such as Figure 1 and Figure 2The air conditioner may include a housing, and a heat exchanger and a wind wheel may be arranged in the housing. The housing is provided with an air inlet, an air outlet and an air duct, and the air inlet and the air outlet are connected to the air duct. The sterilizing device 2 may be arranged at the air inlet, at the air outlet, or in the air duct (such as in the gap between the heat exchanger and the wind wheel).

[0026] The sterilization device 2 mainly plays a sterilization role. The sterilization device 2 can generate streamer discharge under the action of a high-voltage power supply with voltage changes such as a pulse power supply and an AC power supply, and ionize the air through a strong electric field to produce sterilizing substances. The sterilizing substances may include strong oxidizing substances, which can oxidize and decompose bacteria in the air, thereby playing a sterilizing role.

[0027] When the air outlet of the air conditioner is closed, the sterilizing substances (such as strong oxidizing substances) produced by the sterilizing device 2 can diffuse in the housing to every corner of the air conditioner cavity, achieving sterilization in the cavity. When the air outlet of the air conditioner is open, the sterilizing substances produced by the sterilizing device 2 can also diffuse into the indoor space with the air outlet of the air conditioner, playing a sterilizing role in the indoor space.

[0028] Therefore, the air conditioner provided in the embodiment of the present application can not only disinfect bacteria in the space, but also disinfect bacteria attached to the inner cavity of the air conditioner (such as the impeller, heat exchanger and other structures), and has a simple structure and high reliability.

[0029] Of course, the sterilization device 2 provided in the embodiment of the present application can also be used independently.

[0030] In the embodiments of the present application, the type of air conditioner is not limited. For example, the air conditioner can be a split air conditioner or an integrated air conditioner. The split air conditioner can be a wall-mounted air conditioner or a floor-standing air conditioner, and can include only the air conditioner indoor unit of the split air conditioner or a complete split air conditioner.

[0031] Specifically, Figure 1 and Figure 2 As shown, the sterilization device 2 includes: an insulating mounting frame 1, a discharge assembly and an insulating barrier 3.

[0032] like Figure 1 As shown, the insulating mounting frame 1 is provided with an air flow channel 13. When the sterilizing device 2 is mounted on the air conditioner, the air flow is sent to the air conditioner cavity to communicate with the air conditioner cavity, thereby ensuring that the sterilizing substance generated by the sterilizing device 2 through discharge can be released in the air conditioner cavity. The material of the insulating mounting frame 1 can be, but is not limited to, plastic material.

[0033] like Figure 1 and Figure 2As shown, the discharge assembly includes an emitter 21 and a receiver 22 that are relatively spaced apart. The emitter 21 and the receiver 22 are mounted on the insulating mounting frame 1 and are located in the airflow channel 13. Among them, the emitter 21 can be a high-voltage electrode, connected to the high-voltage end of the high-voltage power supply. The receiver 22 can be a low-voltage electrode or a ground electrode, connected to the low-voltage end or the ground end of the high-voltage power supply. Alternatively, the connection mode of the emitter 21 and the receiver 22 with the high-voltage power supply can be exchanged, so that the emitter 21 can be a ground electrode or a low-voltage electrode, and the receiver 22 can be a high-voltage electrode. The insulating mounting frame 1 can be provided with a corresponding electrical interface for the emitter 21 and the receiver 22 to be electrically connected to the high-voltage power supply.

[0034] like Figure 1 and Figure 2 As shown, the insulating barrier 3 is provided on the insulating mounting frame 1 and is partially located between the emitter 21 and the receiver 22, and a portion of the insulating barrier 3 is located outside the airflow channel 13. The insulating barrier 3 is configured to increase the creepage distance between the emitter 21 and the receiver 22. The material of the insulating barrier 3 may be, but is not limited to, plastic material.

[0035] The sterilization device 2 provided in the embodiment of the present application is provided with an insulating barrier 3, so that condensation must flow along the surface of the insulating barrier 3 and bypass the insulating barrier 3, so that the emitter 21 and the receiver 22 can be connected through the condensed water to cause creepage. Therefore, the insulating barrier 3 can increase the creepage distance between the emitter 21 and the receiver 22, increase the difficulty of creepage, and thus help prevent the sterilization device 2 from causing creepage due to condensation, thereby helping to improve the reliability and safety of the sterilization device 2 and the air conditioner.

[0036] In addition, a portion of the insulating barrier 3 is located between the emitter 21 and the receiver 22, and a portion of the insulating barrier 3 is located outside the airflow channel 13 of the insulating mounting frame 1. This is beneficial to reducing the occupation of the airflow channel 13 by the insulating barrier 3 and seriously affecting the gas flow in the airflow channel 13, and is also beneficial to increasing the creepage distance between the emitter 21 and the receiver 22 from multiple directions (such as from the front, side, back, etc. of the sterilization device 2), thereby minimizing the risk of creepage due to condensation in the sterilization device 2, and allowing the sterilization device 2 to operate safely and stably.

[0037] In some exemplary embodiments, the insulating barrier 3 is a plate-shaped structure, and the insulating barrier 3 is an insulating baffle, which has a simple structure and is easy to process and shape, which is beneficial to simplifying the structure of the sterilization device 2 and reducing production costs.

[0038] Of course, the insulating barrier 3 is not limited to a plate-like structure, but may also be a block structure, a cylindrical structure, etc. The insulating barrier 3 is connected to the insulating mounting frame 1, and the insulating barrier 3 may be arranged through the insulating mounting frame 1 or around the insulating mounting frame 1.

[0039] In some exemplary embodiments, the number of the emitter 21 is at least one, such as Figure 1 and Figure 2 The number of receiving electrodes 22 is at least two, as shown in FIG. Figure 1 and Figure 2 As shown. The emitter 21 includes a conductive body 211 and two discharge portions 212. The conductive body 211 is a plate-like structure. The two discharge portions 212 are arranged opposite to each other at two ends of the width direction of the conductive body 211. The discharge portion 212 includes a plurality of discharge tips 2121 arranged along the length direction of the conductive body 211. The receiving electrode 22 is arranged on both sides of the width direction of the conductive body 211.

[0040] like Figure 1 and Figure 2 As shown, the emitter 21 includes a conductive body 211 and two discharge portions 212 respectively disposed at both ends of the conductive body 211 in the width direction, and a receiving electrode 22 is disposed opposite each discharge portion 212. In this way, one emitter 21 can correspond to two receiving electrodes 22, thereby forming two strong electric fields, which is conducive to generating more sterilizing substances, and saves one emitter 21, simplifies the structure of the sterilization device 2, and reduces the production cost.

[0041] Each discharge portion 212 includes a plurality of discharge tips 2121, and the discharge tips 2121 can strengthen the discharge intensity, thereby strengthening the degree of ionization of the air, which is conducive to producing more sterilizing substances. The shape of the discharge tip 2121 can be, but is not limited to, a triangle, a trapezoid, a sawtooth shape, etc. The plurality of discharge tips 2121 of each discharge portion 212 can be arranged at intervals (such as equal intervals), or can be adjacent to each other without intervals. The two discharge portions 212 can be symmetrically arranged at both ends of the conductive body 211, or can be appropriately staggered in the length direction of the conductive body 211.

[0042] The conductive body 211 is a plate-like structure (or sheet-like structure), which can be in the shape of a long strip (such as a rectangle), and the two discharge portions 212 are arranged opposite to each other at the two ends of the width direction of the conductive body 211, and face the receiving electrode 22 arranged on both sides of the width direction of the conductive body 211. Therefore, the discharge tip 2121 of the discharge portion 212 is also arranged to be tapered along the width direction of the conductive body 211. In this way, a conductive sheet can be directly processed and formed to obtain an integrally formed emitter 21. Compared with the scheme of inserting or welding a needle-like structure on the plate surface of the plate-like structure to form the discharge tip 2121, this scheme has lower processing difficulty and is easy to process and form. The width of the conductive body 211 can be greater than the protruding length of the discharge tip 2121 (that is, the size of the discharge tip 2121 along the width direction of the conductive body 211). In this way, there is a certain distance between the two discharge portions 212 of an emitter 21, and it is not easy to affect each other during discharge to cause the emitter 21 to be broken down and damaged, which is conducive to ensuring the reliability of the use of the emitter 21.

[0043] Among them, an insulating barrier 3 is provided between any emitter 21 and receiving electrode 22 to prevent creepage due to condensation between any emitter 21 and the adjacent receiving electrode 22. In other words, the insulating barrier 3 needs to be provided at the part where the insulating material is connected between the emitter 21 and the receiving electrode 22 of the discharge component to increase the creepage distance and prevent creepage.

[0044] In some exemplary embodiments, the receiving electrode 22 is also a plate-shaped structure, and the width direction of the conductive body 211 is perpendicular to the thickness direction of the receiving electrode 22. Figure 1 and Figure 2 shown.

[0045] In other words, the emitter 21 and the receiver 22 are both plate-shaped structures and are perpendicular to each other. In this way, the arrangement of the emitter 21 and the receiver 22 is relatively regular, which is convenient for assembly and fixing on the insulating mounting frame 1.

[0046] In some exemplary embodiments, Figure 2 As shown, the insulating mounting frame 1 includes a mounting seat 11 and a mounting cover 12, and the mounting seat 11 is connected to the mounting cover 12. The emitter 21 and the receiving electrode 22 are fixed to the mounting cover 12. The mounting seat 11 and the mounting cover 12 can be fixedly connected by means of a buckle 121, a fastener (such as a screw), etc. The mounting seat 11 and the mounting cover 12 can both include a hollow frame structure, so as to form an airflow channel 13 in the insulating mounting frame 1.

[0047] In one embodiment, the mounting seat 11 is provided with a protrusion 111, and the mounting cover 12 is correspondingly provided with a buckle 121, and the buckle 121 is clamped on the buckle 111, so that the mounting cover 12 is connected to the mounting seat 11. During assembly, the mounting cover 12 is directly covered on the mounting seat 11, and the mounting cover 12 is pressed, so that the buckle 121 can be clamped on the buckle 111, and the assembly method is simple and fast. A slot can be set on at least one of the mounting seat 11 and the mounting cover 12, and the receiving electrode 22 and the transmitting electrode 21 can be inserted into the slot at the end. A groove extending along the length direction of the receiving electrode 22 or the transmitting electrode 21 and opening along the assembly direction of the mounting seat 11 and the mounting cover 12 may also be provided on the inner side wall of one of the mounting seat 11 and the mounting cover 12. The receiving electrode 22 or the transmitting electrode 21 is located in the groove. When the mounting seat 11 and the mounting cover 12 are matched, the other blocking groove of the mounting seat 11 and the mounting cover 12 opens along the assembly direction of the mounting seat 11 and the mounting cover 12, thereby limiting the movement of the receiving electrode or the transmitting electrode 21 along the assembly direction of the mounting seat 11 and the mounting cover 12. In some examples, the transmitting electrode 21 is inserted in the middle of the hollow frame of the mounting seat 11 or the mounting cover 12, and the two receiving electrodes 22 are located in the grooves on the inner side walls of the mounting seat 11 and the mounting cover 12.

[0048] Of course, the structural form of the insulating mounting frame 1 is not limited thereto, and the mounting position and fixing method of the emitter 21 and the receiver 22 are also not limited thereto, as long as they can fix the emitter 21 and the receiver 22 .

[0049] In some exemplary embodiments (not shown in the figure), the discharge assembly includes a plurality of emitters 21, such as two, three, or even more emitters 21, arranged at intervals along the thickness direction of the conductive body 211 and located between the two receiving electrodes 22. The thickness direction of the conductive body 211 may be consistent with the thickness direction of the sterilization device 2. In this way, the scheme is equivalent to the discharge assembly of the sterilization device 2 realizing the effect of array arrangement in the thickness direction of the sterilization device 2, and does not increase the volume of the sterilization device 2.

[0050] In some exemplary embodiments (not shown in the figure), the discharge assembly includes a plurality of emitters 21 spaced apart along the width direction of the conductive body 211, and a receiving electrode 22 is provided between any two adjacent emitters 21 in the width direction of the conductive body 211. The width direction of the conductive body 211 may be consistent with the width direction of the sterilization device 2. In this way, the scheme is equivalent to the discharge assembly of the sterilization device 2 realizing the effect of array arrangement in the width direction of the sterilization device 2.

[0051] In some exemplary embodiments (not shown in the figures), a plurality of discharge assemblies may be arranged side by side in the length direction of the sterilization device 2 to achieve an array arrangement effect in the length direction.

[0052] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the emitter 21 and the receiver 22 are arranged relatively spaced apart along a first direction, and the emitter 21 and the receiver 22 extend along a second direction, and the second direction is perpendicular to the first direction.

[0053] like Figure 1 and Figure 2 As shown, both ends of the insulating mounting frame 1 in the second direction are provided with insulating blocking members 3, the two ends of the insulating blocking member 3 in the second direction are respectively marked as a first end 31 and a second end 32, and the two ends of the insulating blocking member 3 in a third direction perpendicular to the first direction and the second direction are respectively marked as a third end 33 and a fourth end 34, the first end 31 is partially located in the air flow channel 13, and the second end 32, the third end 33 and the fourth end 34 are located outside the air flow channel 13.

[0054] The first direction may be the width direction of the sterilization device 2 (also the width direction of the conductive body 211), the second direction may be the length direction of the sterilization device 2 (also the length direction of the conductive body 211), and the third direction may be the thickness direction of the sterilization device 2 (also the thickness direction of the conductive body 211).

[0055] The two ends of the emitter 21 in the length direction are respectively connected to the two ends of the insulating mounting frame 1 in the second direction, and the two ends of the receiving electrode 22 in the length direction are respectively connected to the two ends of the insulating mounting frame 1 in the second direction. The insulating blocking member 3 can be respectively blocked at the connection between the emitter 21, the receiving electrode 22 and the two ends of the insulating mounting frame 1 in the second direction of the insulating mounting frame 1. The connection is usually a location where condensation is easily generated. The insulating blocking member 3 can play a good role in preventing creepage. The insulating mounting frame 1 can be a hollow frame structure that is basically in the shape of a cube, and the two ends of the insulating mounting frame 1 in the second direction correspond to the two opposite faces of the cube.

[0056] like Figure 1 and Figure 2 As shown, the first end 31 of the insulating barrier 3 is the end of the insulating barrier 3 inserted into the airflow channel 13, and the second end 32 is the end disposed opposite to the first end 31 and located outside the airflow channel 13. However, since the length of the first end 31 in the third direction is greater than the length of the airflow channel 13 in the third direction, only a portion of the first end 31 is located in the airflow channel 13, and both sides extend out of the airflow channel 13, so the third end 33 and the fourth section of the insulating barrier 3 are both located outside the airflow channel 13.

[0057] In this way, the insulating blocking member 3 can prevent the emitter 21 and the receiving electrode 22 from creeping due to condensation in the air flow channel 13 (i.e., prevent creeping inside the sterilizing device 2), and can also prevent the sterilizing device 2 from creeping outside the air flow channel 13 (e.g., from the side or back of the insulating mounting frame 1). In other words, the insulating blocking member 3 can effectively prevent the sterilizing device 2 from creeping from multiple directions.

[0058] The insulating barrier 3 and the insulating mounting frame 1 can be an integrated structure or a split assembly structure. The insulating barrier 3 is inserted into the insulating mounting frame 1. The insulating barrier 3 itself can be an integrated structure or a split structure, and each component is separately installed at the corresponding position of the insulating mounting frame 1.

[0059] In some exemplary embodiments, the insulating mounting frame 1 has an inner wall surface 14 , and the inner wall surface 14 encloses an air flow channel 13 .

[0060] The distance between the emitter 21 and the receiver 22 in the first direction is denoted as d1.

[0061] The distance between the first end 31 of the insulating barrier 3 and the end of the inner wall surface 14 close to the first end 31 in the second direction is d2, and the distance between the second end 32 of the insulating barrier 3 and the end of the inner wall surface 14 close to the second end 32 in the second direction is d3.

[0062] The distance between the third end 33 of the insulating barrier 3 and one end of the emitter 21 or the receiver 22 closer to the third end 33 (for example, the end of the emitter 21 and the receiver 22 closer to the third end 33) in the third direction is recorded as d4, and the distance between the fourth end 34 of the insulating barrier 3 and one end of the emitter 21 or the receiver 22 closer to the fourth end 34 (for example, the end of the emitter 21 and the receiver 22 closer to the fourth end 34) in the third direction is recorded as d5.

[0063] The minimum creepage distance between the emitter 21 and the receiver 22 is s=d1+2×d2, and d1+2×d3≥s, d1+2×d4≥s, and d1+2×d5≥s.

[0064] If the insulating barrier 3 is not provided, the shortest creepage distance between the emitter 21 and the receiver 22 is d1. After the insulating barrier 3 is provided: if creepage occurs through the first end 31 of the insulating barrier 3 inside the insulating mounting frame 1, the creepage path length = d1 + 2 × d2; if creepage occurs through the second end 32 of the insulating barrier 3 outside the insulating mounting frame 1, the creepage path length = d1 + 2 × d3; if creepage occurs through the third end 33 of the insulating barrier 3 outside the insulating mounting frame 1, the creepage path length = d1 + 2 × d4; if creepage occurs through the fourth end 34 of the insulating barrier 3 outside the insulating mounting frame 1, the creepage path length = d1 + 2 × d5.

[0065] Since d3, d4, and d5 are all greater than d2, the shortest creepage path between the emitter 21 and the receiver 22 is located on the inner side of the insulating mounting frame 1, and the shortest creepage distance s between the emitter 21 and the receiver 22 becomes d1+2×d2, and the shortest creepage distance is increased by twice d2, which is beneficial to prevent creepage due to condensation and can prevent creepage from occurring on the inner and outer sides of the insulating mounting frame 1.

[0066] In some exemplary embodiments, s is set to be positively correlated with the voltage U between the emitter 21 and the receiver 22 , that is, the voltage between the emitter 21 and the receiver 22 is denoted as U, and s is positively correlated with U.

[0067] In other words, when the voltage U between the emitter 21 and the receiver 22 is higher, s is larger. Because the higher the voltage U, the higher the risk of creepage, the shortest creepage distance s needs to be set larger accordingly to reduce the risk of creepage.

[0068] The size of s can be increased by increasing the size of d1 and / or increasing the size of d2. When d1 remains unchanged, the minimum creepage distance can be increased by reasonably increasing the size of the insulating barrier 3, thereby achieving a good anti-creeping effect.

[0069] In some exemplary embodiments, based on the voltage U≤6 kV between the emitter 21 and the receiver 22 , s≥1.5×d1. Based on the voltage 6 kV<U≤8 kV between the emitter 21 and the receiver 22 , s≥2×d1.

[0070] In other words, when the voltage between the emitter 21 and the receiver 22 is within 6 kV, the shortest creepage distance s between the emitter 21 and the receiver 22 is greater than or equal to 1.5 times of d1.

[0071] When the voltage between the emitter 21 and the receiver 22 is within 8 kV, the shortest creepage distance between the emitter 21 and the receiver 22 is greater than or equal to twice of d1.

[0072] Of course, the relationship between U and s is not limited to the above range and can be adjusted as needed.

[0073] In some exemplary embodiments, the distance between the insulating barrier 3 and the receiving electrode 22 in the first direction (i.e., the minimum distance between the insulating barrier 3 and the receiving electrode 22) is recorded as D1, and the distance between the insulating barrier 3 and the emitter 21 in the first direction (i.e., the minimum distance between the insulating barrier 3 and the emitter 21) is recorded as D2.

[0074] Among them, D1≥2.5mm, D2≥2.5mm.

[0075] Setting D1 and D2 to be greater than or equal to 2.5 mm is beneficial to preventing condensation from producing droplets that would significantly shorten the creepage distance between the emitter 21 and the receiving electrode 22. It is also beneficial to preventing the insulating barrier 3 from being directly connected to either electrode (emitter 21 or receiving electrode 22) through the droplets, thereby further reducing the risk of creepage.

[0076] Of course, the sizes of D1 and D2 are not limited to the above ranges and can be adjusted as needed.

[0077] In some exemplary embodiments, the length of the emitter 21 or the receiving electrode 22 is L, for example, the longest electrode length in the emitter 21 or the receiving electrode 22 is L, L≥10d2, further reducing the part of the insulating barrier 3 located in the insulating mounting frame 1 that hinders the discharge of the emitter 21 and the receiving electrode 22.

[0078] In some exemplary embodiments, at least one of the surface of the insulating mounting frame 1 and the surface of the insulating barrier 3 is provided with a hydrophobic layer.

[0079] In other exemplary embodiments, at least one of the insulating mounting frame 1 and the insulating barrier 3 is made of a hydrophobic material.

[0080] The hydrophobic material may be, but is not limited to, polytetrafluoroethylene (PTFE), fluorinated polymer, silicone rubber, fluororubber, and the like.

[0081] In this way, condensation is easy to form water droplets on the surface of the insulating mounting parts and the insulating barrier 3 and slide down, but it is not easy to form a water film on the surface of the insulating mounting frame 1 and the insulating barrier 3, thereby reducing the possibility of condensation water film formation causing the two poles (emitter 21 and receiving electrode 22) of the discharge component to be turned on, and further reducing the possibility of creepage in the sterilization device 2.

[0082] Some embodiments of the present application are tested below.

[0083] like Figure 1 and Figure 2As shown, the sterilization device 2 includes an insulating mounting frame 1, a discharge assembly and four plate-shaped insulating barriers 3. The discharge assembly includes an emitter 21 and two receiving electrodes 22. The emitter 21 includes a plate-shaped conductive body 211 and two discharge portions 212, each of which includes a plurality of discharge tips 2121 arranged along the length direction. The receiving electrode 22 is a plate-shaped structure.

[0084] The sterilization device 2 (d1 = 10 mm) was installed in the middle area of ​​the gap between the heat exchanger and the wind wheel in the air conditioner, and operated for 2 hours (3 minutes of cooling, 3 minutes of stopping, and so on) under the working room conditions of 28°C, 70% relative humidity, and 23°C air conditioner setting temperature, and the sterilization device 2 was monitored for creepage. The instantaneous current of creepage increases sharply, which will trigger the circuit protection and shut down the sterilization device 2.

[0085] The test results are as follows:

[0086] Voltage U Minimum creepage distance Whether creepage Creepage time 6kV d1 yes 40min 6kV 1.5×d1 no - 8kV d1 yes 20min 8kV 1.5×d1 yes 60min 8kV 2×d1 no -

[0087] To sum up, the sterilization device and air conditioner provided in the embodiments of the present application can increase the creepage distance between the emitter and the receiver by setting an insulating barrier of a certain size on the insulating mounting frame connecting the emitter and the receiver, so that the distance between the emitter and the receiver through surface condensation water is greatly increased, thereby greatly improving the creepage difficulty, so that even if condensation occurs inside the air conditioner, creepage will not occur, so that the sterilization device can operate safely and stably.
