DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0040] For the purposes of the description, reference can be made to spatially relative terms, such as "on", "above", "at", "below", "up", "down", and the like, to describe the spatial relationship between various elements. It is to be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if a device is inverted, then the elements described as being "above" or "up" other elements would then be oriented "below" or "down" relative to the other elements. Thus, the exemplary term "above" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. The terms "first", "second", and the like, as used herein do not have any specific meaning and are used only to distinguish one element from another.

[0041] In addition, it should be noted that the use of "first", "second", and the like, to describe various components is merely intended to differentiate one component from another, and does not have any special meaning, and therefore cannot be understood as limiting the scope of protection of the present application.

[0042] In combination with the drawings, Figure 1 As shown in the drawings, according to the embodiments of the present application, an air conditioner defrosting mechanism is provided, which comprises a vinegar water storage mechanism 1 and a conveying mechanism. The vinegar water storage mechanism 1 is used to store vinegar water. The conveying mechanism is used to convey the vinegar water in the vinegar water storage mechanism 1 to the evaporator 10 of the air conditioner, so as to clean the evaporator 10.

[0043] Since the vinegar water has the effect of defrosting, in the above example, the present application can clean the frost on the evaporator 10 by conveying the vinegar water to the evaporator 10 of the air conditioner, so as to achieve the purpose of defrosting. Compared with the prior art, the technical scheme of the present application does not need to set an electric heater, so as to reduce the cost.

[0044] In some embodiments, the aforementioned vinegar water can be household vinegar or the like, which can be obtained by purchasing on the market.

[0045] In order to realize the function of the aforementioned vinegar water storage mechanism 1, in some embodiments, the aforementioned vinegar water storage mechanism 1 can comprise a storage tank to store the vinegar water through the storage tank. The storage tank can be provided with a liquid level display window and a vinegar water filling port, so as to facilitate the observation of the liquid level of the vinegar water and timely supplement.

[0046] The storage tank can be made of high-strength, vinegar water corrosion-resistant materials (such as stainless steel or polypropylene), and the storage tank is placed in the air conditioner indoor unit. The storage tank can be fixed at the right side bottom shell of the air conditioner indoor unit, so as to avoid the influence of direct sunlight and high-temperature components.

[0047] In some embodiments, the defrosting mechanism of the air conditioner further comprises a detection mechanism for detecting whether the evaporator 10 is frosted, so as to control the conveying mechanism to be opened when the evaporator 10 is frosted, and to be closed when the evaporator 10 is not frosted, thus facilitating automatic control.

[0048] In order to realize the function of the detection mechanism, in some embodiments, the aforementioned detection mechanism can comprise a temperature sensor 3, a humidity sensor 4, an air flow sensor 5 and a frost thickness sensor 6. The temperature sensor 3 is used to detect the surface temperature of the evaporator 10; the humidity sensor 4 is used to detect the humidity of the air inlet of the air conditioner; the air flow sensor 5 is used to detect the air flow on the air outlet side of the evaporator 10; and the frost thickness sensor 6 is used to detect the frost thickness on the surface of the evaporator 10. The detection mechanism detects whether the evaporator 10 is frosted through the temperature sensor 3, the humidity sensor 4, the air flow sensor 5 and the frost thickness sensor 6.

[0049] In the above example, compared with the prior art scheme of detecting whether the evaporator 10 is frosted by using a single type of sensor, the present application detects whether the evaporator 10 is frosted through the four different types of sensors (i.e. the aforementioned temperature sensor 3, humidity sensor 4, air flow sensor 5 and frost thickness sensor 6), which is conducive to improving the detection accuracy of whether the evaporator 10 is frosted.

[0050] The aforementioned frost thickness sensor 6 can be installed on one side of the surface of the evaporator 10, which measures the frost thickness based on the principle of laser reflection or capacitance change.

[0051] The aforementioned humidity sensor 4 can be installed in the air inlet duct above the indoor unit of the air conditioner. The air flow sensor 5 can be installed near the air outlet side of the evaporator 10. Both the humidity sensor 4 and the air flow sensor 5 are stably installed and do not affect the air flow, thus providing a basis for frost judgment.

[0052] It should be noted that the aforementioned temperature sensor 3, humidity sensor 4, air flow sensor 5 and frost thickness sensor 6 are all encapsulated for protection, so as to prolong the service life.

[0053] In a specific application example, when the temperature sensor 3 detects that the surface temperature of the evaporator 10 continuously decreases within a set time period and is lower than a preset temperature, the humidity sensor 4 detects that the humidity of the air inlet of the air conditioner exceeds a preset humidity, the air flow sensor 5 detects that the air flow on the air outlet side of the evaporator 10 is less than a preset flow, and the frost thickness sensor 6 detects that the frost thickness on the surface of the evaporator 10 is greater than or equal to a preset thickness, it is determined that the evaporator 10 has been frosted; otherwise, it is determined that the evaporator 10 is not frosted.

[0054] It should be noted that the above judgment process can be completed in the controller to facilitate automatic control.

[0055] In some embodiments, the preset temperature can be a dew point temperature or close to the dew point temperature. The preset humidity is a relative humidity, which is 70%. The preset thickness is 2 mm.

[0056] In some embodiments, as shown in Figure 1 The number of temperature sensors 3 can be two or more, and can be distributed at the bending and edge positions of the evaporator 10. A larger number of temperature sensors 3 can improve the detection accuracy of the surface temperature of the evaporator 10. In addition, by arranging the temperature sensors 3 at the bending and edge positions of the evaporator 10, the interference with the heat exchange between the evaporator 10 and the incoming air can be reduced.

[0057] In some embodiments, each temperature sensor 3 is fixed to the evaporator 10 by heat-conducting glue, so that the temperature sensor 3 can accurately obtain the temperature change of the surface of the evaporator 10.

[0058] In order to realize the function of the conveying mechanism, in some embodiments, as shown in Figure 1 The conveying mechanism can include a first pump body 2 and a spray head 7. The first pump body 2 can be an electric pump or the like. The conveying mechanism conveys the vinegar water in the vinegar water storage mechanism 1 to the spray head 7 through the first pump body 2, so as to spray the vinegar water onto the evaporator 10 through the spray head 7.

[0059] In the above example, the first pump body 2 and the spray head 7 cooperate to spray the vinegar water in the vinegar water storage mechanism 1 onto the evaporator 10, realize the cleaning of the evaporator 10, and achieve the defrosting purpose.

[0060] In some embodiments, as shown in Figure 1 The first pump body 2 is in communication with the spray head 7 through a liquid conveying pipeline 11. The number of spray heads 7 is two or more, and each spray head 7 is in communication with the liquid conveying pipeline 11 through a corresponding branch pipeline 12. The number of branch pipelines 12 is equal to and corresponds to the number of spray heads 7, so that the liquid conveying pipeline 11 can simultaneously convey vinegar water to each spray head 7 for spraying.

[0061] Each spray head 7 can be a PP plastic spray head. The installation angle and height of each spray head 7 can be designed according to the actual situation of the air conditioner, and the size and distribution of the spray holes on each spray head 7 are reasonable, so as to ensure that the vinegar water uniformly covers the surface of the evaporator 10 and the fin gap.

[0062] In some embodiments, the defrosting mechanism of the air conditioner further comprises a vinegar water recycling mechanism. The vinegar water recycling mechanism is used to recycle the vinegar water dropped from the evaporator 10 into the vinegar water storage mechanism 1, so as to recycle the vinegar water, reduce unnecessary energy consumption, reduce resource waste and environmental pollution, and meet the energy saving and environmental protection requirements.

[0063] In order to realize the function of the aforementioned vinegar water recycling mechanism, in some embodiments, as shown in Figure 1 The aforementioned vinegar water recycling mechanism comprises a recycling groove body 9 and a second pump body 15. The second pump body 15 can be an electric pump or the like. The recycling groove body 9 is used to be arranged below the evaporator 10. The vinegar water recycling mechanism receives the vinegar water dropped from the evaporator 10 through the groove opening 901 of the recycling groove body, and pumps the vinegar water in the recycling groove body 9 into the vinegar water storage mechanism 1 through the second pump body 15.

[0064] In the above example, the recycling groove body 9 can be located directly below the evaporator 10. The vinegar water on the evaporator 10 can drop into the recycling groove body 9 under the action of its own gravity, and then the second pump body 15 pumps the vinegar water in the recycling groove body 9 into the vinegar water storage mechanism 1, thereby realizing the recycling of the vinegar water on the evaporator 10.

[0065] It should be noted that the aforementioned first pump body 2 can be a small electric pump resistant to corrosion, and the aforementioned infusion pipeline 11 can be made of polypropylene (PP) material resistant to low temperature and vinegar water. The first electric pump can be installed on the outlet pipeline of the storage tank and is in sealed connection with the storage tank. The aforementioned infusion pipeline 11 is laid along the internal frame of the air conditioner indoor unit to avoid sharp angle bending and interference. The infusion pipeline 11 is fixed by a fixed clamp to ensure stability. The aforementioned second pump body 15 can be in communication with the storage tank through a PP pipeline, and the second pump body 15 pumps the vinegar water in the recycling groove body 9 into the storage tank of the vinegar water storage mechanism 1 through another infusion pipeline 13. The another infusion pipeline 13 can be a PP pipeline.

[0066] In some embodiments, as shown in Figure 2 The aforementioned air conditioner defrosting mechanism further comprises a filter 14 for filtering the vinegar water dropped into the recycling groove body 9, so as to filter out the sundries washed from the evaporator 10, and make the recycled vinegar water cleaner. The filter 14 can be activated carbon.

[0067] In some embodiments, as shown in Figure 2As shown, the filter 14 can be arranged in the recovery tank 9, and separates the recovery tank 9 into an upper cavity 91 and a lower cavity 92, and the slot 901 of the recovery tank is located in the upper cavity 91. The inlet of the second pump 15 is arranged at the bottom of the lower cavity 92, so as to facilitate the suction of the vinegar water recovered in the lower cavity 92. The water level sensor 16 is arranged in the lower cavity 92. The bottom of the lower cavity 92 is provided with an openable and closable drain port, and the drain port is connected with a drain pipe.

[0068] The water level sensor 16 is used to detect the water level in the lower cavity 92. When the water level in the lower cavity 92 reaches a preset height, the second pump 15 is started, so that the second pump 15 can timely recover the vinegar water recovered in the lower cavity 92 into the vinegar water storage mechanism 1. The excess vinegar water in the lower cavity 92 can be drained through the drain port.

[0069] In some embodiments, the air conditioner defrosting mechanism further comprises a detection mechanism, and the detection mechanism comprises the temperature sensor 3, the humidity sensor 4, the air flow sensor 5 and the frost thickness sensor 6, and the conveying mechanism comprises the first pump 2. The air conditioner defrosting mechanism further comprises a controller, and the temperature sensor 3, the humidity sensor 4, the air flow sensor 5, the frost thickness sensor 6, the first pump 2, the second pump 15 and the water level sensor 16 are electrically connected with the controller.

[0070] The controller is used to control the first pump 2 to start when the temperature sensor 3 detects that the surface temperature of the evaporator 10 continuously decreases within a set time period and is lower than a preset temperature, the humidity sensor 4 detects that the humidity of the air entering the air conditioner exceeds a preset humidity, the air flow sensor 5 detects that the air flow on the air outlet side of the evaporator 10 is less than a preset flow, and the frost thickness sensor 6 detects that the frost thickness on the surface of the evaporator 10 is greater than or equal to a preset thickness, and to control the first pump 2 to stop otherwise. The controller is also used to control the second pump 15 to start when the water level in the lower cavity 92 reaches a preset height, and to control the second pump 15 to stop otherwise.

[0071] It should be noted that the temperature sensor 3, the humidity sensor 4, the air flow sensor 5, the frost thickness sensor 6, the first pump 2, the second pump 15 and the water level sensor 16 can be electrically connected with the terminal of the controller through shielded cables, and the shielded cables can be arranged along the wire slot to avoid contact with high temperature and moving parts. The branch pipe 12, the nozzle 7, the other liquid conveying pipe 13, the recovery tank 9 and the storage tank can be connected through sealing pipe fittings (such as a sleeve joint or a flange connection), and sealing gaskets are arranged to prevent leakage of vinegar water.

[0072] The frost layer thickness sensor 6, the humidity sensor 4, the air flow sensor 5 and the water level sensor 16 can realize intelligent identification of frost, and further realize efficient defrosting and effective utilization of resources.

[0073] The utility model discloses still provide a kind of air conditioner indoor unit, it includes the defrosting mechanism of air conditioner of any one of above.

[0074] The utility model discloses still provide a kind of air conditioner, it includes the defrosting mechanism of air conditioner of any one of above;Or including above-mentioned air conditioner indoor unit. Among them, since air conditioner adopts the defrosting mechanism of air conditioner of above, since vinegar water has the effect of defrosting, the utility model can make frost on evaporator 10 be cleaned by being washed to it by delivering vinegar water to evaporator 10 of air conditioner, to reach the purpose of defrosting. Relative to prior art, the technical scheme of the utility model does not need to set electric heater, to reduce cost.

[0075] The utility model can reach the purpose of defrosting by the first pump body 2 even spraying vinegar water (low concentration) in evaporator 10 inside, make the frost on the surface of evaporator 10 can be cleaned in time, it also has certain function of removing peculiar smell, sterilization etc. In addition, the utility model also realizes the recycling of vinegar water by setting recovery groove 9 (including filter piece 14) in the bottom of air conditioner indoor unit, not only resource-saving but also environmental protection. Among them, vinegar water dropped from evaporator 10 can also play certain cleaning effect to cross-flow fan blade 8 in air conditioner indoor unit.

[0076] The working principle of the utility model is as follows: according to the design requirements, the installation position of each component in the air conditioner indoor unit is determined, and each part is connected after installation, as shown in Figure 1 Before starting, the air conditioner initializes and calibrates each sensor, reads the liquid level sensor data on the storage tank, and issues an alarm if the vinegar water level in the storage tank is lower than the set value.

[0077] In normal operation of the air conditioner, the temperature sensor 3 monitors the temperature of the evaporator 10 in real time, the humidity sensor 4 monitors the humidity of the inlet air, and the air flow sensor 5 monitors the air flow on the outlet side of the evaporator 10. When the surface temperature of the evaporator 10 continues to drop to close to or below the dew point temperature, and the humidity is high (the relative humidity is more than 70%), and the air flow is significantly reduced, combined with the data of the frost thickness sensor 6, when the frost thickness reaches 2mm, it is judged that the evaporator 10 is frosted, and the defrosting program is started. Start the first pump body 2, adjust the speed of the first pump body according to the frost thickness and the temperature of the evaporator 10 and other parameters, control the vinegar water flow. The vinegar water is transmitted to the spray head 7 through the liquid pipeline 11, and is uniformly sprayed on the surface of the evaporator 10 to melt the frost. The vinegar water drops on the cross-flow fan blade 8 to clean it to a certain extent, and the vinegar water itself can also eliminate odors. Finally, after being filtered by the filter 14 in the recovery tank 9, the vinegar water is returned to the storage tank to achieve resource recycling. When the frost thickness is reduced to below 0.5mm and the surface temperature of the evaporator 10 rises to above 5℃, the controller controls the first pump body 2 to stop running, ends the defrosting program, and the air conditioner resumes normal operation and continues to monitor the state of the evaporator 10.
