Description

Technical Field

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

[0002] The dehumidification method of existing window air conditioners is usually cooling dehumidification. When dehumidification is achieved, the air conditioner must blow cold air to reduce the indoor temperature. In fact, users may only want dehumidification instead of cooling, and the cooling dehumidification solution cannot provide users with other options.

[0003] The dehumidification scheme of existing window air conditioners is usually cooling and dehumidification. In this scheme, the dehumidification mode is actually a special cooling mode. The difference is that through the setting of software logic, the cooling time, wind speed and other conditions are controlled, and the condensation effect of the indoor evaporator is fully utilized to dehumidify the water vapor entering the indoor air. In principle, this scheme is still a cooling scheme, and users need to accept the actual result that the room temperature is also lowered in the dehumidification mode.

[0004] There are two most important shortcomings of the refrigeration and dehumidification solution. The first is that the dehumidification and cooling modes cannot be completely distinguished. For users, they usually cannot fully understand the similarities and differences between the two modes. They often think that the room temperature should not continue to be lowered when the air conditioner is running in the "dehumidification mode". However, the drainage action is usually not intuitively reflected on the window air conditioner, which makes it impossible for users to intuitively distinguish the two modes, resulting in a lack of experience and misunderstanding of the air conditioner's capabilities, which ultimately affects the product's reputation. The second is that the refrigeration and dehumidification solution does not handle condensed water perfectly. During refrigeration and dehumidification, the evaporator produces a large amount of condensed water. When the water hanging capacity reaches the upper limit, there will usually be a certain amount of small water droplets blown out of the air outlet with the operation of the fan. This is an objective phenomenon that is difficult to completely avoid due to the upper limit of the air conditioner's own capacity. The longer the air conditioner runs, the more obvious this phenomenon will be. Even when the dehumidification capacity is large, a small amount of condensation may form on the panel around the air outlet. However, for window air conditioners, the internal fan and internal panel are not hung on the wall like wall mounted air conditioners, but are placed at the edge of the window, which means that the air outlet and air inlet of the air conditioner are relatively low, especially the air outlet is closer to the user, and the user can directly touch the air outlet. The user can feel the condensation or water discharge phenomenon more intuitively, and the experience is poor. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Figure 1 FIG. 1 is a schematic diagram of a refrigeration cycle system of a window air conditioner according to an embodiment of the present invention. Figure 1As shown, the refrigeration cycle system of the window air conditioner 10 of this embodiment can generally be a compression refrigeration cycle system. The compression refrigeration cycle releases cold energy through the refrigerant compression cycle. The compression refrigeration cycle generally has four major components, namely, the compressor 300, the condenser 200, the throttling device 400 and the evaporator 100.

[0048] The condenser 200 is a heat exchange device that uses the environment to cool the refrigerant, takes away the heat of the high-temperature and high-pressure refrigeration vapor from the compressor 300, and cools and condenses the high-temperature and high-pressure refrigerant vapor into a high-pressure and room-temperature refrigerant liquid.

[0049] The refrigerant liquid at high pressure and normal temperature passes through the throttling device 400 to obtain low temperature and low pressure refrigerant, which is then sent to the evaporator 100 to absorb heat and evaporate. According to the corresponding principle of saturated pressure and saturated temperature, the temperature of the refrigerant liquid can be reduced by reducing the pressure of the refrigerant liquid. In this embodiment, the throttling device 400 is configured as an electronic expansion valve 400. The electronic expansion valve 400 is arranged in series with the evaporator 100 of the air conditioner to control the flow of the refrigerant entering the evaporator 100.

[0050] The evaporator 100 serves as another heat exchange device. The throttled low-temperature and low-pressure refrigerant liquid evaporates (boils) into steam therein, absorbs ambient heat, and reduces the ambient temperature, thereby achieving the purpose of refrigeration.

[0051] The refrigeration cycle system can be implemented by a compression refrigeration cycle, which utilizes the compression phase change cycle of the refrigerant in the compressor 300, the condenser 200, the evaporator 100, and the throttling device 400 to realize the transfer of heat. In the air conditioner, the refrigeration cycle system can also be provided with a reversing valve to change the flow direction of the refrigerant so that the heat exchanger of the indoor unit alternately serves as the evaporator 100 or the condenser 200 to achieve the cooling or heating function. Since the compression refrigeration cycle in the air conditioner is well known to those skilled in the art, its working principle and structure are not described again. In this embodiment, the compressor 300 uses a variable frequency compressor 300, and the throttling device 400 uses an electronic expansion valve 400 with an adjustable opening.

[0052] The window air conditioner 10 of this embodiment includes an indoor unit and an outdoor unit. The window air conditioner 10 of this embodiment completes the cooling and heating cycle of the air conditioner through the effective cooperation of the indoor unit and the outdoor unit, thereby realizing the cold and hot regulation of the indoor ambient temperature. The condenser 200 is arranged in the outdoor unit. The evaporator 100 is arranged in the indoor unit.

Figure 2As shown, the indoor unit of the window air conditioner 10 of this embodiment includes an indoor unit casing 110, an evaporator 100 and a heating device 800. The indoor unit casing 110 is provided with an indoor air inlet 101 and an indoor air outlet 102 to form a through air flow channel. The heating device 800 is arranged at the indoor air outlet 102 of the window air conditioner 10, and is used to heat the blown heat exchange air flow. In some embodiments, the heating device 800 can be a heating resistance wire.

Figure 3 As shown, the control device 500 of the window air conditioner 10 of this embodiment includes a processor 510 and a memory 520. The memory 520 stores a control program 521, which is used to implement the control method of the window air conditioner 10 when executed by the processor 510.

[0055] The memory 520 may be a volatile memory (English: volatile memory), such as a random access memory (English: random-access memory, abbreviated: RAM); the memory 520 may also be a non-volatile memory (English: non-volatile memory), such as a read-only memory (English: read-only memory, abbreviated: ROM), a flash memory (English: flash memory), a hard disk drive (English: hard disk drive, abbreviated: HDD) or a solid-state drive (English: solid-state drive, abbreviated: SSD), or the memory 520 is any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory 520 may be a combination of the above memories 520.

[0056] The processor 510 is used to execute the program code stored in the memory 520, specifically to execute the above Figure 5 as well as Figure 6 The method of the corresponding embodiment.

[0057] Figure 4 FIG. 1 is a schematic block diagram of a window air conditioner according to an embodiment of the present invention. Figure 4As shown, the window air conditioner 10 of this embodiment may include a room temperature sensor 600, a thermostat 700 and a control device 500. The room temperature sensor 600 is arranged in the working area of ​​the window air conditioner 10, and is used to detect the indoor ambient temperature. The thermostat 700 is connected to the heating device 800, and is used to control the heating temperature of the heating device 800. The control device 500 can be connected to the thermostat 700 and the room temperature sensor 600, and is used to control the thermostat 700 or obtain the room temperature information of the room temperature sensor 600.

[0058] Figure 5 1 is a schematic step diagram of a control method for a window air conditioner according to an embodiment of the present invention.

[0059] like Figure 5 As shown, the control method of the window air conditioner 10 of this embodiment includes:

[0060] Step S502, obtaining an operation mode change signal. The operation modes include a dehumidification mode, a cooling mode, and a heating mode. In the dehumidification mode, the window air conditioner 10 of the present embodiment dehumidifies the room. In the cooling mode, the window air conditioner 10 of the present embodiment cools the room. In the heating mode, the window air conditioner 10 of the present embodiment heats the room. The operation mode change signal includes an operation mode change to a dehumidification mode, an operation mode change to a cooling mode, and an operation mode change to a heating mode.

[0061] Step S504, changing the operating state according to the operating mode change signal. The operating state includes the on state of each component. When the operating mode change signal indicates that the operating mode is changed to the dehumidification mode, the step of changing the operating state includes: turning on the heating device 800 and turning on the compressor 300 of the air conditioner. When the operating mode change signal indicates that the operating mode is changed to the cooling mode, the step of changing the operating state includes: turning off the heating device 800 and turning on the compressor 300 of the air conditioner. When the operating mode change signal indicates that the operating mode is changed to the heating mode, the step of changing the operating state includes: turning on the heating device 800 and turning off the compressor 300 of the air conditioner.

[0062] Step S506, determining whether the changed operation mode is the dehumidification mode. If yes, executing step S508.

[0063] Step S508, obtaining the indoor environment temperature.

[0064] Step S510, determining the opening of the electronic expansion valve 400 and the heating temperature of the heating device 800 according to the indoor ambient temperature, so that the air outlet temperature of the indoor unit is equal to the indoor ambient temperature. Wherein, the step of determining the opening of the electronic expansion valve 400 according to the indoor ambient temperature in step S508 may include: determining the opening of the electronic expansion valve 400 according to the corresponding relationship between the preset indoor ambient temperature and the opening of the electronic expansion valve 400. The step of determining the opening of the heating device 800 according to the indoor ambient temperature in step S508 may include: determining the heating temperature of the heating device 800 according to the corresponding relationship between the preset indoor ambient temperature and the heating temperature of the heating device 800.

[0065] The window air conditioner 10 of this embodiment can distinguish between two modes: cooling and dehumidification. When dehumidifying, no cold air will be blown, and the room temperature will hardly be changed, only the purpose of dehumidification is achieved. At the same time, when dehumidifying, the indoor air outlet 102 is a mixture of cold and hot air, and the outlet air temperature is relatively uniform. When the air is discharged, smaller water droplets will be caused to evaporate by the hotter temperature air, and no obvious condensation phenomenon will be formed, nor will it be intuitively felt by the user, thereby improving the user experience.

[0066] Figure 6 FIG. 1 is a schematic diagram of a control method for a window air conditioner 10 according to another embodiment of the present invention. Figure 6 As shown, a control method of a window air conditioner 10 according to another embodiment of the present invention includes:

[0067] Step S602, obtaining an operation mode change signal. The operation modes include a dehumidification mode, a cooling mode, and a heating mode. In the dehumidification mode, the window air conditioner 10 of the present embodiment dehumidifies the room. In the cooling mode, the window air conditioner 10 of the present embodiment cools the room. In the heating mode, the window air conditioner 10 of the present embodiment heats the room. The operation mode change signal includes an operation mode change to a dehumidification mode, an operation mode change to a cooling mode, and an operation mode change to a heating mode.

[0068] In step S604, when the operation mode change signal indicates that the operation mode has been changed to the dehumidification mode, step S610 is executed.

[0069] Step S610, turning on the heating device 800, and turning on the compressor 300 of the air conditioner. Execute step S616.

[0070] In step S606, when the operation mode change signal indicates that the operation mode is changed to the heating mode, step S612 is executed.

[0071] Step S612, turning on the heating device 800 and turning off the compressor 300 of the air conditioner.

[0072] In step S608, when the operation mode change signal indicates that the operation mode has been changed to the cooling mode, step S614 is executed.

[0073] Step S614, turning off the heating device 800 and turning on the compressor 300 of the air conditioner.

[0074] Step S616, obtaining the indoor ambient temperature.

[0075] Step S618 , determining the opening degree of the electronic expansion valve 400 according to the corresponding relationship between the preset indoor ambient temperature and the opening degree of the electronic expansion valve 400 .

[0076] Step S620, determining the heating temperature according to the correspondence between the preset indoor ambient temperature and the heating temperature of the heating device 800. In some embodiments, the heating device 800 is a heating resistance wire, and the step of determining the heating temperature of the heating device 800 according to the correspondence between the preset indoor ambient temperature and the heating temperature of the heating device 800 may include: determining the resistance value of the heating resistance wire according to the correspondence between the preset indoor ambient temperature and the resistance value, and then determining the heating temperature.

[0077] The indoor ambient temperature is subdivided into multiple ranges. It is stipulated that within a certain temperature range, the ambient temperature interval is set with a fixed temperature zone interval as a step. For example: within the range of 16°C-36°C, the ambient temperature interval is set with a step of 4°C, and the indoor ambient temperature is ≤16°C, 16°C<indoor ambient temperature≤20°C...32°C<indoor ambient temperature≤36°C, 36°C<indoor ambient temperature, and each interval corresponds to an opening degree of an electronic expansion valve 400 and a heating temperature of a heating device 800.

[0078] The valve openings of the plurality of electronic expansion valves 400 are preset, and the number thereof is consistent with and corresponds to the temperature range of the indoor ambient temperature. When the indoor ambient temperature actually falls into the corresponding range, the opening of the electronic expansion valve 400 takes a value according to the preset value, thereby changing the cold air temperature of the indoor air outlet 102 by adjusting the refrigerant flow rate.

[0079] The heating temperatures of the plurality of heating devices 800 are preset, and the number is consistent with the temperature range of the indoor ambient temperature and corresponds to each other. When the indoor ambient temperature actually falls into the corresponding range, the heating device 800 automatically takes a value according to the corresponding preset value, thereby setting the target temperature through the heating device 800 and changing the hot air temperature of the air outlet 102.

[0080] Through dual regulation of the electronic expansion valve 400 and the heating device 800, the mixed air outlet temperature can be consistent with the room temperature.

[0081] When the indoor ambient temperature changes, the valve opening of the electronic expansion valve 400 and the heating temperature of the heating device 800 change accordingly to ensure that the outlet air mixing temperature is moderate and consistent with the room temperature.

[0082] In cooling mode, the heating device 800 is not started, the valve opening of the electronic expansion valve 400 is taken according to the preset value of the cooling mode, and the air conditioner executes the cooling logic. In heating mode, the compressor 300 is not started, the refrigerant does not flow, the air supply fan of the indoor unit is running to supply air, the air passing through the evaporator 100 is at room temperature, the heating device 800 is heated according to the heating target temperature, and the heated air is sent out. In dehumidification mode, the heating device 800 and the compressor 300 are started at the same time, the control device 500 reads the detection value of the temperature sensor, determines whether the room temperature falls into the ambient temperature range, and finds the electronic expansion valve 400 and the valve opening preset value and the heating temperature of the heating device 800 according to the range. The electronic expansion valve 400 and the thermostat 700 respond to the corresponding values ​​respectively.

[0083] The control method of the window air conditioner 10 of the present embodiment comprises: a heating device 800, which is arranged at the indoor air outlet 102 of the window air conditioner 10, and is used to heat the blown refrigerated air; an electronic expansion valve 400, which is arranged in series with the evaporator 100 of the air conditioner, and is used to control the flow of the refrigerant entering the evaporator 100; the control method comprises: obtaining an operation mode change signal; changing the operation state according to the operation mode change signal; obtaining the indoor ambient temperature; determining the opening of the electronic expansion valve 400 and the heating temperature of the heating device 800 according to the indoor ambient temperature, so that the air outlet temperature of the indoor unit is equal to the indoor ambient temperature.
