It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
In the prior art, an air return structure is arranged in an air conditioner indoor unit, and when the air conditioner runs, indoor air is sucked into an air duct through a return air grille, a filter screen and an evaporator in a negative pressure mode and then is blown out. The filter screen plays the effect of filtering dust, sterilization, therefore can gather the dust after the filter screen live time is long, leads to the indoor side amount of wind of air conditioner to reduce refrigeration effect and descends, and the filter screen easily breeds the bacterium and influences user health. However, the filter screen of the existing window type air conditioner is cleaned mainly by manual disassembly and is very inconvenient.
In order to solve the problems in the prior art, the present embodiment provides a window type air conditioner, which is briefly stated, the window type air conditioner provided in the present embodiment is to spray the collected and stored condensed water onto the filter screen by collecting the condensed water generated on the evaporator, so as to clean the filter screen in the window type air conditioner without manual disassembly.
In the present embodiment, a window type air conditioner is provided, as shown in fig. 1, which includes a condenser 10 and an evaporator 20, which are important components in a cooling/heating system. Typically, the condenser 10 is disposed on the outdoor side of the window air conditioner and the evaporator 20 is disposed on the indoor side of the window air conditioner. For installation of a window type air conditioner, the window type air conditioner is generally installed on a window, the outdoor side of the window type air conditioner faces outdoors, and the indoor side of the window type air conditioner faces indoors. When the window type air conditioner is in a refrigerating state, the condenser 10 is used for converting gas or vapor into condensed liquid, and when the low-temperature condensed liquid passes through the evaporator 20, the condensed liquid can exchange heat with the outside air, so that the heat is absorbed through gasification, and the refrigerating effect is achieved. In order to realize the heat exchange process between the condensed liquid in the evaporator 20 and the external air, an air inlet end is arranged on the evaporator 20, and the air inlet end is used for enabling the external air to enter an air channel. Because often mix dust or other unidentified particulate matters in the outside air, dust or other unidentified particulate matters cause the damage to the spare part of air conditioner after getting into the wind channel easily, influence the normal operating of air conditioner, consequently in order to prevent dust or other unidentified particulate matters entering wind channel in the outside air, the air inlet end of evaporimeter 20 still is provided with filter screen 30, filter screen 30 can block dust and other unidentified particulate matters entering wind channel in the outside air, in order to ensure the normal operating of spare part in the window type air conditioner.
Since the external air is formed by mixing dry air and a certain amount of water vapor, that is, the external air is humid air with a certain humidity, when the temperature of the coil surface of the evaporator 20 in the window type air conditioner is lower than the temperature of the intake air at the air intake end, water vapor condensation occurs on the coil surface of the evaporator 20, thereby generating condensed water. In one embodiment, as shown in fig. 1, a water receiving tray 40 is disposed below the evaporator 20, and the water receiving tray 40 is used for receiving condensed water generated on the evaporator 20. In one implementation, the drip tray 40 is disposed directly below the evaporator 20 to ensure that all of the condensate falls into the drip tray 40 as much as possible. In view of the fact that the present invention realizes the automatic cleaning process of the window type air conditioner by recycling the condensed water generated on the evaporator 20, a water collecting tank 50 (as shown in fig. 1) for collecting and storing the condensed water is further provided below the evaporator 20. After the water pan 40 receives the condensed water generated by the evaporator 20, the condensed water needs to be drained to the water collecting tank 50 for storage, so in an implementation manner, the water pan 40 is disposed between the evaporator 20 and the filter screen 30, and the water pan 40 is located below the evaporator 20 and connected to the water collecting tank 50, so as to implement the functions of receiving the condensed water and draining the condensed water to the water collecting tank 50. In one implementation, the water collection trough 50 is disposed outside of the outdoor side of the window air conditioner and on the chassis 60 of the window air conditioner. In a specific application, as shown in fig. 2, the water collecting tank 50 is disposed at the lowest point of the bottom plate of the window type air conditioner, that is, the water collecting tank 50 is a component at the lowest position in the window type air conditioner, so that a certain height difference is generated between the water collecting tank 50 and the water receiving tray 40, a better drainage effect is achieved, and the condensed water in the water receiving tray 40 can conveniently flow into the water collecting tank 50.
In one implementation, as shown in fig. 1, a water outlet 70 for discharging condensed water is further disposed on the water pan 40, and the water outlet 70 is further communicated with the water collection tank 50 to guide the condensed water discharged from the water pan 40 to the water collection tank 50, that is, after the condensed water produced on the evaporator falls into the water pan 40, the condensed water can enter the water collection tank 50 through the water outlet 70 and be collected and stored by the water collection tank 50. In a specific application, the water outlet 70 may be an inclined tubular structure, wherein the higher end of the water outlet 70 is connected to the water pan 40, and the lower end of the water outlet 70 is connected to the water collecting tank 50, so as to achieve a better drainage effect.
When the condensed water is collected in the water collecting tank 50, the condensed water collected and stored in the water collecting tank 50 is required to be used for cleaning the filter screen 30, so as to clean the filter screen 30 and utilize the condensed water. In order to utilize the condensed water, the present embodiment needs to provide a water intake device in the water collection tank 50 for taking out the condensed water collected and stored in the water collection tank 50 to clean the filter screen 30. In one implementation, the water intake device is a water pump 80, as shown in fig. 1, the water pump 80 is disposed in the water collection tank 50, and the water pump 80 can extract the condensed water in the water collection tank 50. Specifically, the window air conditioner in this embodiment may be set to a cleaning mode, which may be opened by one key of the remote controller, and when the cleaning mode of the window air conditioner is opened, the water pump 80 is synchronously opened. The time for opening the cleaning mode of the window type air conditioner can be set by a user, and in one implementation mode, the cleaning mode can be automatically opened after the accumulated running of the window type air conditioner reaches the preset time. When the cleaning mode of the window type air conditioner is started, the water suction pump 80 is started synchronously, and condensed water stored in the water collection tank 50 can be pumped out after the water suction pump 80 is started.
In one implementation, as shown in fig. 1, the water pump 80 is connected to a water conduit 100, and a water outlet of the water conduit 100 is disposed toward the filter screen 30, that is, the water conduit 100 is used to guide the water pumped by the water pump 80 from the water collecting tank 50 to the filter screen 30, so as to automatically clean the filter screen 30. In one implementation, a nozzle 110 (shown in fig. 1) is further disposed on the water outlet of the water conduit 100, and the nozzle 110 is used for spraying water in the water conduit 100 onto the filter screen 30 to achieve a better cleaning effect. Since the filter screen 30 has a certain width, it is difficult to achieve full coverage of the filter screen 30 with a single nozzle, and thus in one implementation, the number of nozzles 110 may be multiple. Specifically, the plurality of nozzles 110 may be disposed at intervals in the length direction of the filter screen 30, and the plurality of nozzles 110 are spaced at equal intervals to ensure that the filter screen 30 can be cleaned uniformly and stably in the coverage area of the nozzles 110. In one implementation, the user may set the cleaning duration of the filter screen 30, i.e., the duration of the operation of the window type air conditioner after the cleaning mode is turned on. When the cleaning mode of the window type air conditioner is started and the cleaning duration preset by a user is reached, the filter screen 30 is completely cleaned, the cleaning mode of the window type air conditioner is closed at the moment, meanwhile, the water suction pump 80 stops pumping water, and the nozzle 110 stops spraying water.
In addition, in order to prevent the condensed water stored in the water collecting tank 50 from containing fine particles and affecting the normal operation of the water pump 80, in one implementation, a filtering device 90 (as shown in fig. 1) is further disposed on the water pump 80, and the filtering device 90 is configured to filter the condensed water stored in the water collecting tank 50 and prevent the particles in the condensed water from being sucked into the water pump 80, so as to ensure the normal operation of the water pump 80.
When the filter screen 30 is cleaned, the water sprayed from the nozzle 110 may drive the dust or other particles on the filter screen 30 to fall onto the chassis 60, and then flow into the water collection tank 50 located at the lowest point of the chassis 60 along with the water flow, so that after the filter screen 30 is cleaned, a lot of impurities are inevitably generated in the water collection tank 50, and at this time, the remaining water in the water collection tank 50 cannot be used for cleaning the filter screen 30 next time due to excessive impurities. Therefore, in one implementation, a drain valve 120 (as shown in fig. 2) is disposed in the water collection tank 50, and the drain valve 120 is opened to drain the water containing impurities in the water collection tank 50, so as to ensure that the water in the water collection tank for cleaning the filter screen 30 is clean and free of impurities. Specifically, after the filter screen 30 is cleaned, a large amount of particles cleaned from the filter screen 30 flow into the water collection tank 50, so that the water in the water collection tank 50 is not suitable for reuse, and the liquid and the particulate impurities in the water collection tank 50 can be discharged by opening the drain valve 120. After the liquid and particulate impurities in the water collecting tank 50 are discharged, the water collecting tank 50 can continue to collect and store the condensed water from the water receiving tray 40 by closing the drain valve 120, and the water collected by the water collecting tank 50 does not contain excessive impurities, so that the water can be used for cleaning the filter screen 30 next time.
In a specific application, when the water amount in the water collecting tank 50 is too small, the cleaning mode of the window type air conditioner is started, the water pump 80 cannot pump water, and if the water pump 80 forcibly works when the water level is too low, an idling phenomenon may occur, and the pump body is damaged. Therefore, in order to avoid the above situation, it is necessary to monitor the water level inside the water collecting tank 50, and in one implementation, a water level monitor 130 (as shown in fig. 1) is disposed inside the water collecting tank 50, and the water level monitor 130 is connected to the water pump 80 and the water discharge valve 120 respectively. Specifically, the user may set a first water level for the water level monitor 130, where the first water level is the lowest water level in the water collecting tank 50 when the water pump 80 pumps water normally. When the washing mode of the window type air conditioner is turned on, the water level monitor 130 first monitors whether the current water level of the water collection tank 50 reaches the first water level, and if the current water level of the water collection tank 50 reaches the first water level, the water suction pump 80 is started; and if the current water level of the water collection tank 50 does not reach the first water level, the water pump 80 is suspended to be started until the current water level of the water collection tank 50 reaches the first water level. After the filter screen 30 is cleaned, the water collecting tank 50 can store water in time in order to better control the closing time of the drain valve 120. The user may set a second water level for the water level monitor 130, which is the corresponding water level in the water collection tank 50 when the drain valve 120 is closed. After the filter screen 30 is cleaned, the drain valve 120 is opened to drain the liquid and particulate impurities in the water collection tank 50, when the water level monitor 130 detects that the water level has decreased to a second predetermined water level, the drain valve 120 is closed, and after the drain valve 120 is closed, the water collection tank 50 can perform a new cycle of water collection.
In order to achieve a better cleaning effect, in one implementation, as shown in fig. 2, a sterilization device 140 is further disposed outside the filter screen 30. The sterilization device 140 is used for sterilizing the filter screen 30 and the air passing through the filter screen 30, so as to ensure the cleanliness of the air at the air outlet. The user can set the start-stop time and the operation time of the sterilization device 140 by himself, and the sterilization device 140 performs sterilization treatment on the filter screen 30 and the air passing through the filter screen 30 according to the preset start-stop time and the preset operation time.
Since the water pump 80 and the drain valve 120 are both in the shutdown state when the window air conditioner is not in the cleaning mode, and at this time, condensed water still occurs and falls into the base plate 60 and then flows into the water collection tank 50 located at the lowest point of the base plate 60, in order to avoid excessive condensed water accumulation in the base plate 60 and the water collection tank 50, in one implementation manner, a fan blade is further disposed on the outdoor side of the window air conditioner, and a water fetching ring for eliminating the condensed water is disposed on the fan blade. Specifically, the outer circumferential surface of the water fetching ring can be also provided with a plurality of water fetching sheets which are similar to a spoon and are deviated to the outdoor side. Specifically, when the fan blade rotates, the water fetching ring on the fan blade is driven to synchronously rotate, so as to drive the water fetching pieces on the water fetching ring to move, when the water fetching pieces move, the condensed water in the chassis 60 or the water collecting tank 50 can be fetched, and then the condensed water is thrown out of a room through the rotation of the fan blade, so that the excessive condensed water accumulated in the chassis 60 or the water collecting tank 50 is avoided, and the heat exchange effect at the outdoor side is improved.
To sum up, the utility model discloses a window type air conditioner, which comprises a condenser and an evaporator, wherein the air inlet end of the evaporator is provided with a filter screen; a water collecting tank is arranged below the evaporator; a water suction pump is arranged in the water collection tank and connected with a water guide pipe, and a water outlet of the water guide pipe faces towards the filter screen. Compare with traditional window formula air conditioner, the utility model discloses a window formula air conditioner need not the artifical clean filter screen of dismantlement, can realize self-cleaning to the filter screen, reduces the probability that the filter screen gathers the dust.
