Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a refrigerator and an air conditioner. Background Art

[0002] Currently, users have higher and higher requirements for the sterilization and purification of household appliances. Ion technology has become the main application technology for sterilization and purification in household appliances due to its broad-spectrum sterilization, broad-spectrum odor removal effect, low cost and high technical maturity. It is widely used in refrigerators and air-conditioning products.

[0003] Generally, ion modules are installed in household appliances for sterilization and purification. Common ion technologies in household appliances include pinpoint corona discharge technology, pinpoint air discharge technology, dielectric barrier discharge (DBD) discharge and surface discharge.

[0004] Different ion technologies can produce different ion types to suit different scenarios. Among them, strong oxidizing functional ions (such as hydroxyl radicals, ozone, atomic oxygen, ground state oxygen and nitrogen oxides, etc.) are mainly used to remove surface attached bacteria and remove odors; positive ions and / or negative ions are mainly used to remove floating bacteria in the air and reduce dust.

[0005] In the related art, a single ion module can only achieve one of the above two forms, and cannot take into account the efficient removal of surface attached bacteria, odor removal, removal of floating bacteria in the air, and dust reduction. When there are multiple needs, it is necessary to achieve them by adding devices, but this will increase the cost of the entire device and affect the size of the refrigerator's storage space or the volume of the air conditioner.

[0116] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that elements, structures, and features in one embodiment may also be beneficially combined in other embodiments without further description.

[0117] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0118] The terms "first", "second" are used only for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first", "second" may explicitly or implicitly include one or more of the features.

[0119] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0120] The present application provides a refrigerator, referring to Figure 1 The refrigerator includes a box body, and a storage space is formed inside the box body. The storage space includes at least a refrigerating chamber 1 and a freezing chamber. In some embodiments, the storage space may also include a vacuum chamber, a fresh-keeping drawer, and a variable temperature chamber to meet different storage needs of users.

[0121] The refrigerator of the present application also includes a door, which includes a door liner 22 and a door shell 21. The door is used to open and close the storage space. The door can be used to form a closed space for the cabinet to facilitate sterilization and deodorization inside the cabinet, prevent the introduction of new bacteria, and cause the air outside the cabinet to pollute the air inside the cabinet.

[0122] The cabinet includes an inner liner 12 defining a storage space, an outer shell 11 connected to the outer side of the inner liner 12 to form the appearance of the refrigerator, and an insulating layer provided between the inner liner 12 and the outer shell 11 to insulate the storage space.

[0123] A main air duct is formed between the inner tank 12 and the outer shell 11, and the main air duct is connected to the storage space inside the box. A refrigeration system is arranged in the main air duct. Cold air generated by the refrigeration system enters the box through the main air duct to cool the food in the box.

[0124] A duct fan 10 is arranged in the main duct to accelerate the air flow rate of the entire main duct and the box body, and the sterilization and purification effect is enhanced by increasing the air circulation in the refrigerating chamber 1 brought about by the operation of the duct fan 10 during the refrigeration process of the refrigerator.

[0125] In the present application, a refrigeration system for supplying cold air to a storage space includes a compressor, a condenser, an expansion valve, and an evaporator. The refrigerant circulates in the various components of the refrigeration system to achieve a refrigeration effect. The main flow process of the refrigerant in each component is: the refrigerant enters the condenser after passing through the compressor, enters the expansion valve after passing through the condenser, enters the evaporator after passing through the expansion valve, and flows back to the compressor after passing through the evaporator.

[0126] Specifically, the compressor compresses the refrigerant gas at high temperature and high pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid phase refrigerant in the high temperature and high pressure state in the condenser into a low pressure liquid phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant or heat exchange with the material to be cooled.

[0153] When the motor 371 is started, the electrode drives the gear 373 to rotate through the electrode rod, and the gear 373 drives the second electrode assembly 34 to move relative to the sliding space 38 through the frame 341, thereby changing the distance between the first electrode assembly 33 and the second electrode assembly 34, and realizing the switching between the first position 381 and the second position 382 of the second electrode assembly 34.

[0154] Specifically, refer to Figure 4-5As shown, the motor 371 can drive the gear 373 to rotate, and the gear 373 and the rack 374 are engaged to drive the rack 374 and the second electrode assembly 34 to move up or down.

[0155] It can be known that the motion mechanism 37 can also be configured as other components that can drive the second electrode assembly 34 to move.

[0156] Reference Figure 5 , the second electrode assembly 34 is driven to the first position 381 by the motion mechanism 37. At this time, the distance between the first electrode assembly 33 and the second electrode assembly 34 is relatively close, and the electric field strength around the first electrode assembly 33 is relatively large. The high-voltage discharge mainly produces strong oxidizing functional ions, among which the strong oxidizing functional ions include hydroxyl radicals (·OH), ozone (O3), atomic oxygen (O), ground state oxygen (O*), nitrogen oxides (NOx), etc. The main function is to effectively remove the attached bacteria on the inner wall of the refrigerator and the surface of food and have a deodorizing effect.

[0157] Reference Figure 4 , the second electrode assembly 34 is driven to the second position 382 by the motion mechanism 37. At this time, the second electrode assembly 34 is far away from the second electrode assembly 34. At this time, the first motor 371 assembly forms a needle-to-air discharge mode, and the amount of strong oxidizing functional ions generated by the discharge decreases. At this time, mainly negative ions and / or positive ions are generated, and the main function is to remove floating bacteria in the air inside the refrigerator and reduce dust, but the removal effect and deodorization effect on the bacteria attached to the inner wall of the refrigerator and the surface of food are relatively weak.

[0158] In some implementations of this embodiment, the refrigerator also includes a built-in fan 7, which can be arranged in the storage space and located on one side of the ion generating device 3, for accelerating the air flow in the storage space, accelerating the diffusion of ions and strong oxidizing active substances, improving the contact efficiency between the air and the ion group in the box, accelerating the deodorization and sterilization, and improving the deodorization efficiency.

[0159] In some implementations of this embodiment, the built-in fan 7 may also be disposed in the accommodating space 35 to accelerate the diffusion of the generated ion group into the storage space, thereby achieving the purpose of improving the sterilization efficiency.

[0160] Reference Fig.23 The refrigerator in the embodiment of the present application further includes a controller 6. The controller 6 obtains various operating parameters of the refrigerator through various control programs stored in the memory, and controls the operation of various parts of the refrigerator and responds to user operations.

[0161] The controller 6 controls the overall operation of the refrigerator. For example, in response to receiving a sterilization and deodorization instruction issued by a user, the controller 6 can perform operations related to the object selected by the sterilization and deodorization instruction.

The processor 83 may also include multiple CPUs, and the processor 83 may be a single-CPU processor 83 or a multi-CPU processor 83. The processor 83 here may refer to one or more devices, circuits, or processing cores for processing data (such as computer program instructions).

[0166] The memory 82 may be a read-only memory 82 (ROM) or other types of static storage devices that can store static information and instructions, a random access memory 82 (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory 82 (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store the desired program code in the form of an instruction or data structure and can be accessed by a computer, and the embodiment of the present application does not impose any restrictions on this. The memory 82 may exist independently or be integrated with the processor 83. Among them, the memory 82 may contain a computer program code. The processor 83 is used to execute the computer program code stored in the memory 82, thereby realizing the control method of the multi-connected refrigerator 100 system provided in the embodiment of the present application.

[0168] The bus 81 may be a peripheral component interconnect (PCI) bus 81 or an extended industry standard architecture (EISA) bus 81, etc. The bus 81 may be divided into an address bus 81, a data bus 81, a control bus 81, etc. For ease of representation, Fig.11 Although only one thick line is used in the figure, it does not mean that there is only one bus 81 or only one type of bus 81.

[0169] In some implementations of this embodiment, the controller 6 is installed on the door 2. Of course, the controller 6 can also be installed on the box body for layout purposes.

[0170] In some implementations of this embodiment, reference Figure 1The refrigerator further includes a door closing detection component 9, which is installed on the door 2 or the box body, and is used to detect the state of the door 2 and send a door opening signal or a door closing signal to the controller 6. Exemplarily, the door closing detection component 9 is set as a door closing detection sensor, which is used to detect whether the box body is in a closed state, and whether it is necessary to remove the floating bacteria.

[0171] In some implementations of this embodiment, when the first signal is received and it is determined that the surface attached bacteria and odor removal functions are to be executed at this time, when the storage space is in a closed state, the first electrode assembly 33 and the high voltage power supply 36 are connected, and the motion mechanism 37 is controlled to drive the second electrode assembly 34 to move to the first position 381, and the first electrode assembly 33 discharges high voltage to generate strong oxidizing ions, which diffuse into the storage space through the opening 32 to remove the attached bacteria in the storage space.

[0172] It can be known that when the above functions are performed, the attached bacteria inside the refrigerator and on the surface of food can be removed and the odor can be purified.

[0173] After receiving the second signal, it is determined to execute the functions of removing airborne bacteria and reducing dust. When the storage space is in a closed state, the first electrode assembly 33 and the high-voltage power supply 36 are connected, and the motion mechanism 37 is controlled to drive the second electrode assembly 34 to move to the second position 382. The first electrode assembly 33 discharges at the tip to generate positive ions and / or negative ions, and the positive ions and / or negative ions diffuse into the storage space through the opening 32 to remove the airborne bacteria in the storage space.

[0174] It should be noted that when the above functions are executed, floating bacteria and dust in the air inside the refrigerator can be removed.

[0175] Through the above steps, by the mobile design of the second electrode assembly 34, the electric field strength between the first electrode assembly 33 and the second electrode assembly 34 is changed, thereby changing the composition of the ion products generated by the high-voltage discharge to perform different sterilization and purification functions.

[0176] Specifically, refer to Figure 6-7 As shown, when the distance between the second electrode assembly 34 (counter electrode) and the first electrode assembly 33 is relatively close and the electric field strength between them is relatively large, strong oxidizing functional ions are mainly generated by high voltage discharge. For example, the strong oxidizing functional ions are hydroxyl radicals, ozone, atomic oxygen, ground state oxygen, nitrogen oxides, etc., and their main functions are to remove surface attached bacteria and remove odors; refer to Figure 8-9 As shown, when the distance between the second electrode assembly 34 (counter electrode) and the first electrode assembly 33 is far and the electric field strength between them is small, the high voltage discharge mainly produces negative ions and / or positive ions, and the main function is to remove floating bacteria and dust in the air.

[0177] The technical solution of the present application can take into account the efficient removal of surface attached bacteria, odor removal, removal of floating bacteria in the air and dust reduction, and the cost is relatively low.

[0178] Reference Fig.18 , illustrating the control logic of sterilization in the embodiment of the present application.

[0179] Determine whether a first signal is received (step S1801);

[0180] In step S1801, if the first signal is received, step S1802 is executed to determine whether the box is in a closed state;

[0181] In step S1802, if the box is in a closed state, step S1804 is executed to connect the ion circuit to drive the second electrode assembly 34 to move to the first position 381;

[0182] In step S1802, if the box is not in the closed state, step S1805 is executed to give an alarm or take no action;

[0183] In step S1801, if the first signal is not received, step S1803 is executed to determine whether the second signal is received;

[0184] In step S1803, if the second signal is received, step S1806 is executed to determine whether the box is in a closed state;

[0185] In step S1806, if the box is in a closed state, step S1808 is executed to connect the ion circuit to drive the second electrode assembly 34 to move to the second position 382;

[0186] In step S1806, if the box is not in the closed state, step S1809 is executed to give an alarm or take no action;

[0187] In step S1803, if the second signal is not received, step S1807 is executed without taking any action.

[0188] In the above steps, when the second electrode assembly 34 moves to the first position 381, the electric field strength around the needle electrode is relatively large, and the high-voltage discharge mainly produces strong oxidizing functional ions and escapes into the refrigerator compartment 1 or the drawer to perform the functions of removing surface bacteria and deodorizing; when the second electrode assembly 34 moves to the second position 382, ​​the high-voltage needle electrode forms a needle-tip-to-air discharge mode, and the amount of strong oxidizing functional ions generated by the discharge decreases, mainly producing negative ions and / or positive ions to remove floating bacteria in the air and reduce dust.

[0189] It should be noted that the dust reduction function is mainly suitable for household purification appliances such as air conditioners and purifiers.

[0190] In some implementations of this embodiment, the controller 6 is configured to turn on the built-in fan 7 upon receiving the first signal or the second signal.

[0196] In step S1901, if the first signal is not received, step S1903 is executed to determine whether the second signal is received;

[0197] In step S1903, if the second signal is received, step S1906 is executed to determine whether the box is in a closed state;

[0198] In step S1906, if the box is in a closed state, step S1908 is executed to connect the ion circuit, turn on the built-in fan 7, and drive the second electrode assembly 34 to move to the second position 382;

[0199] In step S1906, if the box is not in the closed state, step S1909 is executed to give an alarm or take no action;

[0200] In step S1903, if the second signal is not received, step S1907 is executed without taking any action.

[0201] In some implementations of this embodiment, the controller 6 is configured to, during the period when the ion generating device 3 generates ion groups, when the door closing detection component 9 detects that the box is in an open state, close the connection switch 333, cut off the connection between the first electrode component 33 and the high-voltage power supply 36, and stop generating ion groups. This prevents a large amount of strong oxidizing functional ions, positive ions, and negative ions from overflowing to the outside of the box, which affects the health and safety of users.

[0202] In some embodiments of the present application, compared with other embodiments, in this embodiment, reference is made to Fig.10The housing 31 of the ion generating device 3 includes a sliding space 38 , and the sliding space 38 is provided with a first position 381 and a second position 382 along its own length direction. The first position 381 is located on a side of the second position 382 close to the first electrode assembly 33 .

[0203] The second electrode assembly 34 includes a frame 341 , which can be moved along the sliding space 38 to a first position 381 or a second position 382 to realize manual displacement control, and the ring electrode can move with the frame 341 to realize a position change between the ring electrode and the first electrode assembly 33 .

[0204] In some implementations of this embodiment, the sliding space 38 is set as a through hole that penetrates the inside and outside of the housing 31. The sliding space 38 includes a first position 381, a moving area 383, and a second position 382 arranged from bottom to top. Figure 10-12 The width of the second position 382 of the sliding space 38 is greater than the width of the lower position to better fix the frame 341. The first position 381 of the sliding space 38 can be set to be consistent with the width of the second position 382 or to be consistent with the width of the active area. When the width of the first position 381 is consistent with the width of the active area, the frame 341 is fixed using the lower edge of the first position 381.

[0205] In some embodiments, the frame 341 includes a main body 3411 and an elastic portion, wherein the elastic portion may protrude from the surface of the main body 3411 to fix the main body 3411 at the second position 382 , and the elastic portion may retract into the main body 3411 to allow the main body 3411 to move along the sliding space 38 .

[0206] The frame 341 is provided to realize movement and fixation of the ring electrode, thereby ensuring the stability of the discharge process.

[0207] In some implementations of this embodiment, the frame 341 includes a main body 3411 and an elastic part. The main body 3411 also includes a hand-held part 3412, a connecting part 3413 and a movable part 3414. The connecting part 3413 and the hand-held part 3412 can be set as two, which are respectively arranged at the two ends of the movable part 3414, and one end is taken as an example for description.

[0208] The connecting part 3413 is clamped in the sliding space 38, the moving part 3414 is located in the accommodating space 35, and the hand-held part 3412 is arranged in the accommodating space 35. The hand-held part 3412, the connecting part 3413 and the moving part 3414 are connected in sequence, and the moving part 3414 is connected to the second electrode assembly 34. By applying force to the hand-held part 3412, the entire frame 341 is driven to carry the second electrode assembly 34 to move.

[0209] Elastic parts are provided on both sides or one side of the connection part 3413 , and the elastic parts can protrude or retract relative to the side of the connection part 3413 to achieve the position fixation and movement of the frame 341 as a whole.

[0210] In some implementations of this embodiment, the controller 6 is configured to connect the first electrode assembly 33 and the high voltage power supply 36 when receiving the first signal or the second signal;

[0211] When the frame 341 drives the ring electrode to move to the first position 381, the first electrode assembly 33 discharges at high voltage to generate strong oxidizing ions, which diffuse into the storage space through the opening 32 to remove bacteria attached to the storage space;

[0212] When the frame 341 drives the ring electrode to move to the second position 382 , the first electrode assembly 33 discharges at the tip to generate positive ions and / or negative ions, which diffuse into the storage space through the opening 32 to remove floating bacteria in the storage space.

[0213] Reference Fig. 20 , illustrating the control logic of sterilization of the refrigerator in the embodiment of the present application.

[0214] Determine whether a first signal is received (step S2001);

[0215] In step S2001, if the first signal is received, step S2002 is executed to determine whether the box is in a closed state;

[0216] In step S2002, if the box is in a closed state, step S2004 is executed to connect the ion circuit, and the second electrode assembly 34 is driven to move to the first position 381 through the handheld part 3412 and the moving part 3414;

[0217] In step S2002, if the box is not in the closed state, step S2005 is executed to give an alarm or take no action;

[0218] In step S2001, if the first signal is not received, step S2003 is executed to determine whether the second signal is received;

[0219] In step S2003, if the second signal is received, step S2006 is executed to determine whether the box is in a closed state;

[0220] In step S2006, if the box is in the closed state, step S2008 is executed to connect the ion circuit, and the second electrode assembly 34 is driven to move to the second position 382 through the handheld part 3412 and the moving part 3414;

[0221] In step S2006, if the box is not in the closed state, step S2009 is executed to give an alarm or take no action;

[0222] In step S2003, if the second signal is not received, step S2007 is executed without taking any action.

[0223] In the above steps, when the second electrode assembly 34 moves to the first position 381, the electric field strength around the needle electrode is relatively large, and the high-voltage discharge mainly produces strong oxidizing functional ions and escapes into the refrigerator compartment 1 or the drawer to perform the functions of removing surface bacteria and deodorizing; when the second electrode assembly 34 moves to the second position 382, ​​the high-voltage needle electrode forms a needle-tip-to-air discharge mode, and the amount of strong oxidizing functional ions generated by the discharge decreases, mainly producing negative ions and / or positive ions to remove floating bacteria in the air and reduce dust.

[0224] Specifically, the main types of bacteria that need to be removed can be determined based on the received signal, and the position of the second electrode assembly 34 can be adjusted accordingly to achieve precise sterilization while reducing the energy consumption of the refrigerator.

[0225] In the above steps, the operating speed of the built-in fan 7 and the duct fan 10 can be increased to speed up the air flow rate and / or the voltage of the ion circuit can be increased to increase the ion concentration, thereby achieving faster sterilization and improving the sterilization efficiency.

[0226] In some implementations of this embodiment, the working time of the ion generating device 3 is related to the type and quantity of food and the opening time of the box.

[0227] Specifically, the working time of the ion generator 3 is related to the door opening time or the quantity and type of food. Within a certain range, the longer the door opening time is, the longer the second electrode assembly 34 is in the second position 382; the more the number of new food ingredients is, the longer the second electrode assembly 34 is in the first position 381.

[0228] Regarding the type of food, when the food is perishable, the working time of the ion generating device 3 is increased. For example, the perishable food may include strawberries and cherries.

[0229] It can be known that the above-mentioned influencing factors can cumulatively affect the working time of the ion generating unit.

[0230] In some implementations of the present embodiment, in order to accurately sterilize food according to the type of food, the controller 6 is configured to identify the type of food in the box based on the image of the food storage area captured by the image acquisition device, and when the food is on the list of perishable food, determine the corresponding set working time and set working voltage of the sterilization ion generating unit, turn on the sterilization ion generating unit, turn on the built-in fan 7, adjust the voltage output by the high-voltage power supply 36 to the set working voltage to increase the number of ions emitted by the sterilization ion generating unit, and turn off the sterilization ion generating unit after working for the set working time.

[0231] It should be noted that the list of perishable ingredients includes ingredients that are not easy to store and are easy to rot, for example, strawberries and cherries. It can be known that the ingredients in the list of perishable ingredients are selected according to the characteristics of the ingredients themselves.

[0232] Through the above steps, sterilization can be carried out according to the characteristics of the food, avoiding excessive sterilization, which will lead to excessive strong oxidizing ions in the box and oxidize the food, which is not conducive to the preservation of the food; at the same time, reducing energy consumption and achieving quantitative sterilization can improve the user experience.

[0233] In the above embodiment, the refrigerator includes a box body, a box door 2 for opening or closing the box body, a door closing detection component 9 for detecting the switch state of the box body, an ion generating device 3 and a controller 6 for removing bacteria and / or odors in the box body, and the ion generating device 3 further includes: a shell 31 with an opening 32 and a accommodating space 35, a first electrode assembly 33 arranged in the accommodating space 35, a second electrode assembly 34, and a high-voltage power supply 36 for providing a high-voltage voltage; the ion generating device 3 is used to remove odors and / or bacteria in the box body by using the ion group generated by itself; the controller 6 is configured to, when receiving the first signal, when the storage space When in the closed state, the first electrode assembly 33 and the high-voltage power supply 36 are connected, and the second electrode assembly 34 is moved to the first position 381. The first electrode assembly 33 discharges at high voltage to generate strong oxidizing ions, which diffuse into the storage space through the opening 32 to remove the attached bacteria in the storage space; after receiving the second signal, when the storage space is in the closed state, the first electrode assembly 33 and the high-voltage power supply 36 are connected, and the second electrode assembly 34 is moved to the second position 382. The first electrode assembly 33 discharges at the tip to generate positive ions and / or negative ions, which diffuse into the storage space through the opening 32 to remove the floating bacteria in the storage space. By changing the distance between the first electrode assembly 33 and the second electrode assembly 34, the discharge type of the ion generator 3 is adjusted to meet the sterilization requirements of the refrigerator in different scenarios.

[0234] In some embodiments of the present application, an air conditioner is also proposed. The air conditioner includes a refrigeration system for exchanging heat with indoor air to meet cooling or heating needs.

[0235] The refrigeration system includes a compressor, a condenser, an expansion valve and an evaporator. In this application, the air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0236] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0237] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor.

[0238] The evaporator can achieve the refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0239] The outdoor unit of the air conditioner refers to a part of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and the expansion valve may be provided in the indoor unit or the outdoor unit.

[0240] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0241] The air conditioner in the present application can be configured as an integrated unit or a split unit, and can be configured as a cabinet unit or a wall mounted unit.

[0242] Taking an indoor wall mounted unit (not shown in the figure) as an example, the indoor wall mounted unit is usually installed at a location such as an indoor wall. For another example, an indoor cabinet unit (not shown in the figure) is also a form of indoor unit.

[0243] Taking the split unit as an example, the air conditioner includes an indoor unit and an outdoor unit, wherein the outdoor unit is usually installed outdoors and is used for heat exchange in the indoor environment.

[0244] The indoor unit of the air conditioner includes an indoor unit casing 31, which includes an air inlet and an air outlet. Indoor air enters the indoor unit casing 31 through the air inlet, exchanges heat with the internal heat exchanger, and then flows back to the room through the air outlet, thereby changing the indoor temperature.

[0245] The ion generating device 3 is disposed in the indoor unit casing 31 to sterilize the indoor unit casing 31 and prevent the indoor air from being contaminated by the indoor unit.

[0246] The controller 6 is configured to, when receiving the first signal, close the air outlet, control the motion mechanism 37 to drive the second electrode assembly 34 to move to the first position 381, and the first electrode assembly 33 discharges at high voltage to generate strong oxidizing ions, which diffuse into the indoor unit housing 31 through the opening 32 to remove attached bacteria in the indoor unit housing 31;

[0247] After receiving the second signal, the air outlet is closed, the motion mechanism 37 is controlled to drive the second electrode assembly 34 to move to the second position 382, ​​and the first electrode assembly 33 discharges at the tip to generate positive ions and / or negative ions to remove floating bacteria in the indoor unit housing 31.
