Heat pump clothes drying equipment has become the main product type in the existing clothes drying equipment market due to its energy-saving advantage.

[0048] As a household appliance that can quickly dry clothes, clothes drying equipment can also allow people to wear dry and comfortable clothes in humid weather, and reduce the space occupied by drying clothes, thus improving people's quality of life. Therefore, clothes drying equipment is becoming more and more popular among users. However, with the application of clothes drying equipment, people have put forward higher requirements for the quality, speed, uniformity and energy consumption of drying. Heat pump clothes drying equipment has become the main product type in the existing clothes drying equipment market due to its energy-saving advantage. However, since the heat pump system itself heats up slowly, the temperature of the entire clothes drying system rises slowly, so the heat pump clothes drying equipment takes a long time to dry clothes.

[0049] In order to solve the problem of slow heating speed of heat pump clothes dryers, the main solution at present is to use high-power auxiliary heat to turn on the auxiliary heat when the heat pump clothes dryer starts drying, thereby increasing the heating speed of the drying system, and then turn off the auxiliary heat when a certain system temperature is reached. The heating speed of heat pump clothes dryers can be increased by auxiliary heat, but there are the following disadvantages: running auxiliary heat will increase the operating power of the heat pump clothes dryer, increase the power consumption of the heat pump clothes dryer, and is not energy-efficient; auxiliary heat only operates during the heating stage of the heat pump clothes dryer, and is turned off when a certain temperature is reached. Auxiliary heat does not participate in the drying process of the heat pump clothes dryer and cannot effectively increase the drying speed of the heat pump clothes dryer; using auxiliary heat to increase the heating speed of the clothes dryer will also increase the cost of the clothes dryer.

[0050] To this end, the present invention provides a control method for a heat pump clothes drying device, the clothes drying device comprising a compressor, a condenser and a variable frequency fan, the method comprising: collecting the exhaust temperature of the compressor and the outlet temperature of the condenser; adjusting the fan speed of the variable frequency fan based on the exhaust temperature of the compressor and the outlet temperature of the condenser until the variable frequency fan is adjusted to a maximum speed; and controlling the variable frequency fan to operate at the maximum speed.

[0051] The present invention collects the exhaust temperature of the compressor and the outlet temperature of the condenser after the heat pump drying equipment starts to run, and then adjusts the fan speed of the variable frequency fan according to the exhaust temperature and the outlet temperature of the condenser until the variable frequency fan is adjusted to the maximum speed, and controls the operation of the variable frequency fan according to the maximum speed, which can effectively improve the heating speed and drying efficiency of the heat pump drying equipment, and adopts the method of adjusting the fan speed to reduce the operating power of the heat pump drying equipment, save power consumption, and improve the user experience.

[0052] Exemplarily, the heat pump drying device may be a heat pump dryer.

[0053] See attached Figure 1 , Figure 1 1 is a flow chart of main steps of a method for controlling a heat pump clothes drying device according to an embodiment of the present invention.

[0054] like Figure 1 As shown, the heat pump clothes drying device in the embodiment of the present invention includes a compressor, a condenser and a variable frequency fan. The control method of the heat pump clothes drying device in the embodiment of the present invention mainly includes the following steps S100 to S300.

[0055] Step S100: collecting the exhaust temperature of the compressor and the outlet temperature of the condenser.

[0056] In this embodiment, after the heat pump clothes drying device starts to operate, the exhaust temperature of the compressor and the outlet temperature of the condenser are collected by a preset temperature sensor.

[0057] Step S200: adjusting the fan speed of the variable frequency fan based on the exhaust temperature of the compressor and the outlet temperature of the condenser until the variable frequency fan is adjusted to a maximum speed.

[0058] In this embodiment, the fan speed of the variable frequency fan is adjusted according to the exhaust temperature of the compressor and the outlet temperature of the condenser collected in step S100, until the speed of the variable frequency fan is adjusted to the maximum speed.

[0059] Step S300: controlling the variable frequency fan to operate at the maximum speed.

[0060] In this embodiment, the variable frequency fan is controlled to run at the highest speed to dry the clothes.

[0061] Based on the above steps S100-S300, the present invention collects the exhaust temperature of the compressor and the outlet temperature of the condenser after the heat pump drying equipment starts to run, and then adjusts the fan speed of the variable frequency fan according to the exhaust temperature and the outlet temperature of the condenser until the variable frequency fan is adjusted to the maximum speed, and controls the operation of the variable frequency fan according to the maximum speed, which can effectively improve the heating speed and drying efficiency of the heat pump drying equipment, and adopts the method of adjusting the fan speed to reduce the operating power of the heat pump drying equipment, save power consumption, and improve the user experience.

[0062] With respect to step S100: collecting the exhaust temperature of the compressor and the outlet temperature of the condenser.

[0063] In this embodiment, after the heat pump clothes drying device starts to operate, the exhaust temperature of the compressor and the outlet temperature of the condenser are collected by the temperature sensor preset in the heat pump clothes drying device. The exhaust temperature of the compressor is specifically the temperature at the exhaust port of the compressor. The compressor exhaust temperature and the condenser outlet temperature are detected by the temperature sensor provided by the heat pump clothes drying device, and the speed of the variable frequency fan is adjusted in real time according to the compressor exhaust temperature and the condenser outlet temperature, thereby improving the rapid heating effect of the heat pump clothes drying device in the early stage of clothes drying.

[0064] For step S200, in a specific embodiment, the fan speed of the variable frequency fan is adjusted based on the exhaust temperature of the compressor and the outlet temperature of the condenser, including: obtaining a preset fan speed based on the exhaust temperature of the compressor, the outlet temperature of the condenser and a first corresponding relationship, wherein the first corresponding relationship is a corresponding relationship between the exhaust temperature of the compressor, the outlet temperature of the condenser and the preset fan speed; and adjusting the fan speed of the variable frequency fan based on the preset fan speed.

[0065] Specifically, this embodiment presets a first correspondence between the exhaust temperature of the compressor, the outlet temperature of the condenser, and the fan speed, and determines the preset fan speed based on the collected exhaust temperature of the compressor, the outlet temperature of the condenser, and the first correspondence, and then adjusts the fan speed of the variable frequency fan based on the preset fan speed. By real-time monitoring of the exhaust temperature of the compressor and the outlet temperature of the condenser of the heat pump clothes drying equipment, and controlling the fan speed of the variable frequency fan by the exhaust temperature of the compressor and the outlet temperature of the condenser, the heating speed of the heat pump system and the drying efficiency of the heat pump clothes drying equipment are improved.

[0066] In a specific embodiment, the first correspondence relationship includes: when the exhaust temperature of the compressor is within a first exhaust temperature range and the outlet temperature of the condenser is within a first outlet temperature range, the preset fan speed is a first speed; when the exhaust temperature of the compressor is within a second exhaust temperature range and the outlet temperature of the condenser is within a second outlet temperature range, the preset fan speed is a second speed; wherein the second exhaust temperature range is greater than the first exhaust temperature range, the second outlet temperature range is greater than the first outlet temperature range, and the second speed is greater than the first speed.

[0067] In one embodiment, the correspondence relationship between the exhaust temperature of the compressor, the outlet temperature of the condenser, and the fan speed is detected through offline experiments. During the detection process, the exhaust temperature of one compressor combined with the outlet temperature of one condenser corresponds to one fan speed, which can be stored in the database in the form of a table or other forms. Exemplarily, the first correspondence relationship is as follows:

[0068] When the exhaust temperature of the compressor is within the first exhaust temperature range [X1, X2) and the outlet temperature of the condenser is within the first outlet temperature range [Y1, Y2), the variable-frequency fan speed is the A1 speed.

[0069] When the exhaust temperature of the compressor is within the second exhaust temperature range [X2, X3) and the outlet temperature of the condenser is within the second outlet temperature range [Y2, Y3), the variable-frequency fan speed is the A2 speed.

[0070] When the exhaust temperature of the compressor is within the third exhaust temperature range [X3, X4) and the outlet temperature of the condenser is within the second outlet temperature range [Y3, Y4), the variable-frequency fan speed is the A3 speed.

[0071] ……

[0072] When the exhaust temperature of the compressor is within the Nth exhaust temperature range [Xn, Xn + 1) and the outlet temperature of the condenser is within the Nth outlet temperature range [Yn, Yn + 1), the variable-frequency fan speed is the An speed.

[0073] Wherein, X1 < X2 < X3 < X4 < …… < Xn < Xn + 1, Y1 < Y2 < Y3 < Y4 < …… < Yn < Yn + 1, and A1 speed < A2 speed < A3 speed < …… < An speed.

[0074] In a specific embodiment, the method further includes: determining the preset fan speed based on the exhaust temperature of the compressor.

[0075] Specifically, when the exhaust temperature of the compressor and the condenser outlet temperature do not conform to the first corresponding relationship, the preset fan speed is determined according to the fan speed corresponding to the exhaust temperature of the compressor in the first corresponding relationship.

[0076] For example, if it is detected that the exhaust temperature of the compressor is within the second exhaust temperature range [X2, X3) and the outlet temperature of the condenser is within the first outlet temperature range [Y1, Y2), the variable frequency fan speed is determined according to the temperature range corresponding to the exhaust temperature. At this time, the determined variable frequency fan speed is the A2 speed. When the fan speed cannot be determined based on the exhaust temperature of the compressor, the outlet temperature of the condenser and the preset first corresponding relationship, the fan speed is determined only based on the exhaust temperature. Specifically, in the first corresponding relationship, the preset fan speed corresponding to the exhaust temperature of the compressor is used as the fan speed. This can avoid the problem of being unable to adjust the fan speed when the exhaust temperature of the compressor and the outlet temperature of the condenser fail to determine the fan speed.

[0077] In a specific embodiment, after controlling the variable frequency fan to operate at the maximum speed, the method also includes: collecting load humidity information in the heat pump drying equipment; obtaining a preset fan speed based on the load humidity information and a second corresponding relationship, wherein the load humidity information is less than a first humidity threshold, and the second corresponding relationship is a corresponding relationship between the load humidity information and the preset fan speed; and adjusting the fan speed of the variable frequency fan based on the preset fan speed.

[0078] Specifically, after controlling the variable frequency fan to run at the highest speed, the load humidity information in the heat pump clothes drying device is monitored in real time. When the load humidity information is less than the first humidity threshold, it is determined that the load humidity has reached the critical point, and the preset fan speed of the variable frequency fan is determined according to the load humidity information and the preset second corresponding relationship, and then the fan speed of the variable frequency fan is controlled according to the preset fan speed. The speed of the variable frequency fan is adjusted by the load humidity and temperature, and the variable frequency fan is controlled throughout the process. Real-time adjustment can more comprehensively grasp the state of the clothes, reduce the operating power of the heat pump clothes drying device during the adjustment process, and then reduce the power consumption of the heat pump clothes drying device, so as to achieve the purpose of energy saving.

[0079] In a specific embodiment, the second corresponding relationship includes: when the load humidity information is within a first humidity range, the preset fan speed is a third speed; when the load humidity information is within a second humidity range, the preset fan speed is a fourth speed, wherein the first humidity range is greater than the second humidity range, and the third speed is greater than the fourth speed.

[0080] In one embodiment, the corresponding relationship between the load humidity and the fan speed is detected through offline experiments. During the detection process, each load humidity corresponds to a fan speed, which can be stored in a database in the form of a table or other forms. Exemplarily, the second corresponding relationship is as follows:

[0081] When the load humidity information is within the first humidity range [K1, K2), the variable-frequency fan speed is C1 speed.

[0082] When the load humidity information is within the second humidity range [K2, K3), the variable-frequency fan speed is C2 speed.

[0083] When the load humidity information is within the third humidity range [K3, K4), the variable-frequency fan speed is C3 speed.

[0084] ……

[0085] When the load humidity information is within the Nth humidity range [Kn, Kn+1), the variable-frequency fan speed is Cn speed.

[0086] Wherein, K1 < K2 < K3 < K4 < …… < Kn < Kn+1, and C1 speed < C2 speed < C3 speed < …… < Cn speed.

[0087] In a specific embodiment, the method further includes: determining whether the current fan speed is the lowest speed; if so, controlling the variable-frequency fan to operate at the lowest speed until the clothes are completely dried; if not, adjusting the preset fan speed based on the load humidity information and the second corresponding relationship until the variable-frequency fan is adjusted to the lowest speed.

[0088] Specifically, first determine whether the current fan speed is the lowest speed. If so, control the variable-frequency fan to operate at the lowest speed until the loaded clothes are completely dried. When the speed of the variable-frequency fan drops to the lowest speed, the heat pump drying device enters the gentle drying mode. If not, determine the preset fan speed according to the real-time collected load humidity information and the preset second corresponding relationship, and then control the variable-frequency fan to operate according to the preset fan speed. As the load humidity decreases, the speed of the variable-frequency fan gradually decreases until it drops to the lowest speed. Adjusting the speed of the variable-frequency fan according to the real-time humidity of the loaded clothes can ensure that the quality of the clothes is not damaged and improve the drying effect of the drying device.

[0089] Refer to the appendix Figure 2 , Figure 2 is a complete step flow schematic diagram of the control method of the heat pump drying device according to an embodiment of the present invention.

[0090] As Figure 2As shown, a heat pump clothes drying device according to an embodiment of the present invention includes a compressor, a condenser and a variable frequency fan, and a control method of the heat pump clothes drying device includes the following steps:

[0091] Step S01: The heat pump clothes drying device starts to operate.

[0092] Step S02: Collect the exhaust temperature of the compressor and the outlet temperature of the condenser.

[0093] Step S03: Obtaining a preset fan speed based on the exhaust temperature of the compressor, the outlet temperature of the condenser, and a first corresponding relationship. Specifically, the preset fan speed is determined based on the exhaust temperature, the outlet temperature, and the first corresponding relationship; the first corresponding relationship includes a corresponding relationship between the exhaust temperature of the compressor, the outlet temperature of the condenser, and the preset fan speed.

[0094] In a specific embodiment, the speed of the variable frequency fan includes four speeds: a, b, c, and d, wherein speed a includes multiple different speeds a1, a2, a3, a4..., speed b is the highest speed, speed c includes multiple different speeds c1, c2, c3, c4..., and speed d is the lowest speed.

[0095] The preset fan speed is obtained according to the exhaust temperature of the compressor, the outlet temperature of the condenser and the first corresponding relationship. Specifically, as the exhaust temperature of the compressor and the outlet temperature of the condenser change, the speed of the variable frequency fan is gradually increased from speed a to speed b, for example:

[0096] Set the exhaust temperature of the compressor to x1<x2<x3…, the outlet temperature of the condenser to y1<y2<y3…; the speed of the variable frequency fan to a1<a2<a3…

[0097] When the exhaust temperature of the compressor is x1 or the outlet temperature of the condenser is y1, the speed of the variable frequency fan is a1;

[0098] When the exhaust temperature of the compressor is x2 or the outlet temperature of the condenser is y2, the speed of the variable frequency fan is a2;

[0099] When the exhaust temperature of the compressor is x3 or the outlet temperature of the condenser is y3, the speed of the variable frequency fan is a3;

[0100] …

[0101] In this embodiment, if it is detected that the exhaust temperature of the compressor is x2 and the outlet temperature of the condenser is y1, the variable frequency fan speed a2 corresponding to the exhaust temperature x2 is obtained based on the exhaust temperature x2.

[0102] Step S04: adjusting the fan speed of the variable frequency fan according to the preset fan speed.

[0103] Step S05: Determine whether the fan speed of the variable frequency fan is the maximum speed, if so, execute step S06; if not, execute step S03.

[0104] Step S06: Control the variable frequency fan to run at the highest speed. Specifically, control the variable frequency fan to run at the highest speed b to quickly dry the clothes.

[0105] Step S07: Collecting load humidity information in the heat pump clothes drying device.

[0106] Step S08: Determine whether the load humidity information is less than the first humidity threshold, if so, execute step S09; if not, execute step S07. Specifically, when the temperature and humidity sensor inside the heat pump clothes drying device detects that the load humidity information is less than the first humidity threshold, the speed of the variable frequency fan begins to decrease from the maximum speed b to the speed c.

[0107] Step S09: Obtaining a preset fan speed based on the load humidity information and the second corresponding relationship. Specifically, the preset fan speed is determined according to the load humidity information and the second corresponding relationship; the second corresponding relationship includes a corresponding relationship between the load humidity information and the preset fan speed.

[0108] Specifically, when the temperature and humidity sensor inside the heat pump clothes drying device detects that the load humidity information is less than the first humidity threshold, the speed of the variable frequency fan starts to decrease. The speed decrease control logic of the variable frequency fan is as follows:

[0109] When the temperature and humidity sensor inside the heat pump clothes drying device detects that the load humidity information is less than the first humidity threshold, the fan speed of the variable frequency fan is reduced from the maximum speed b to the speed c, and the humidity of the clothes is set to h>h1>h2>h3…, and the variable frequency fan speed is c>c1>c2>c3…

[0110] When the clothing humidity is detected to be h1, the speed of the variable frequency fan is c1;

[0111] When the clothing humidity is detected to be h2, the speed of the variable frequency fan is c2;

[0112] When the clothing humidity is detected to be h3, the speed of the variable frequency fan is c3;

[0113] …

[0114] Step S10: adjusting the fan speed of the variable frequency fan according to the preset fan speed.

[0115] Step S11: determine whether the fan speed of the variable frequency fan is the minimum speed, if so, execute step S12; if not, execute step S09.

[0116] Step S12: Control the variable frequency fan to run at the minimum speed. Specifically, when the fan speed of the variable frequency fan drops to the minimum speed d, the clothes are softly dried.

[0117] Step S13: The heat pump clothes drying device ends its operation.

[0118] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.

[0119] Furthermore, the present invention also provides a control device for a heat pump clothes drying device.

[0120] See attached Figure 3 , Figure 3 1 is a main structural block diagram of a control device for a heat pump clothes drying device according to an embodiment of the present invention.
