Description

TECHNICAL FIELD

[0001] The present application belongs to the field of clothes dryers, and particularly relates to a compressor exhaust temperature control method, device, equipment and medium. BACKGROUND

[0002] When the compressor exhaust temperature is too high, not only will the refrigerant and lubricating oil decompose to generate carbon and acid when contacting with metal and other substances, but also the viscosity of the lubricating oil will be reduced, resulting in excessive wear in the compressor, and even causing the built-in motor of the compressor to burn out. In general, the compressor's life will be affected by the excessively high exhaust temperature. At present, in actual applications, such as clothes dryers with compressors, the compressor exhaust temperature is reduced by increasing the compressor cooling fan. However, this solution requires the addition of an extra cooling fan in the clothes dryer, which is costly, resulting in an increase in the price of the clothes dryer, which is not conducive to popularization. SUMMARY

[0016] In the embodiment of the present application, when it is identified that the exhaust temperature decreases over time and the exhaust temperature exceeds the first threshold value, the opening of the induced draft valve can be reduced to maintain the exhaust temperature of the compressor within the preset standard range, so that the exhaust temperature of the compressor can be maintained within the preset standard range by reducing the opening of the valve when the exhaust temperature of the compressor decreases.

[0019] In some embodiments, the target operation stage is a temperature decreasing stage, the change trend information indicates a temperature decreasing rate of the exhaust temperature over time, and the adjusting the opening of the induced draft valve in the target operation stage according to the exhaust temperature and the change trend information comprises: if the temperature decreasing rate indicated by the change trend information exceeds a second rate and the exhaust temperature is lower than a first threshold value, the opening of the induced draft valve is reduced to maintain the exhaust temperature of the compressor within a preset standard range.

[0020] In the embodiment of the present application, when it is identified that the temperature decreasing rate of the exhaust temperature exceeds a second rate and the exhaust temperature is lower than a first threshold value, the opening of the induced draft valve can be reduced to maintain the exhaust temperature of the compressor within a preset standard range, so that the exhaust temperature of the compressor can be maintained within the preset standard range by reducing the opening of the valve when the exhaust temperature of the compressor decreases.

[0021] In some embodiments, the exhaust parameter further comprises an exhaust pressure, the target operation stage is a temperature increasing stage, and the adjusting the opening of the induced draft valve in the target operation stage according to the exhaust temperature and the change trend information to adjust the exhaust temperature of the compressor comprises: if the change trend information indicates that the exhaust pressure increases over time and the exhaust temperature exceeds a first threshold value, the opening of the induced draft valve is increased to a preset upper limit opening to reduce the exhaust temperature of the compressor.

[0022] In the embodiment of the present application, when it is identified that the exhaust pressure shows an upward trend over time and the exhaust temperature exceeds the first threshold value, the opening of the induced draft valve can be increased to a preset upper limit opening to reduce the exhaust temperature of the compressor. In this way, when the exhaust temperature of the compressor is high and the exhaust pressure gradually increases, the exhaust temperature of the compressor can be reduced by increasing the opening of the valve, thereby protecting the compressor from damage.

[0023] In some embodiments, the exhaust parameter further includes an exhaust pressure, the target operation stage is a temperature reduction stage, and the adjusting the opening of the induced draft valve in the target operation stage according to the exhaust temperature and the trend information to adjust the exhaust temperature of the compressor includes: if the trend information indicates that the exhaust pressure shows a downward trend or a stable trend over time and the exhaust temperature exceeds the first threshold value, the opening of the induced draft valve is reduced to maintain the exhaust temperature of the compressor within a preset standard range.

[0039] In view of the technical problem of high cost caused by increasing the compressor cooling fan to reduce the exhaust temperature of the compressor in the prior art, an embodiment of the present application provides a compressor exhaust temperature control method, device, equipment and medium. When it is detected that the compressor is in a target running stage, the exhaust parameters of the compressor are acquired, the exhaust parameters at least including the exhaust temperature, the change trend information of the exhaust parameters changing over time is acquired, and finally the opening of the air inlet valve in the target running stage is adjusted according to the acquired exhaust temperature and change trend information, so that the exhaust temperature of the compressor is intelligently and conveniently adjusted, the compressor is protected from damage, the equipment cost is saved, and the equipment promotion degree is improved.

[0040] In order to make the objects, technical solutions and advantages of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0041] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0042] In the following, the control method for the exhaust temperature of the compressor provided by the embodiments of the present application will be described in detail with reference to the drawings and specific embodiments.

[0043] Please refer to Figure 1 is a flowchart of a control method for the exhaust temperature of the compressor provided by the embodiments of the present application. As Figure 1 indicated, the method can be applied to household appliances configured with a compressor and an air induction valve, which can be household appliances for adjusting the exhaust temperature of the compressor, for example, the household appliances include but are not limited to a clothes dryer, an air conditioner, an air conditioner fan, a fresh air device, an electric heater or other devices. The method includes the following implementation steps:

[0044] S101, when it is detected that the compressor is in a target operating phase, acquiring an exhaust parameter of the compressor, the exhaust parameter at least including an exhaust temperature of the compressor.

[0045] The target operating phase of the present application refers to the operating phase of the compressor at present, and the division standard is not limited, for example, according to the change trend of the exhaust temperature of the compressor, which can be divided into a temperature rising phase and a temperature falling phase. The exhaust parameter refers to a related parameter for describing the exhaust of the compressor, which can include but is not limited to the exhaust temperature, the exhaust pressure, the exhaust time, the exhaust volume or other exhaust parameters.

[0046] In practical applications, in a household appliance (for example, a clothes dryer or an air conditioner), the present application can monitor whether the compressor in the household appliance enters a target operating stage in real time or periodically during operation of the household appliance, and then implement the control scheme of the compressor discharge temperature provided by the present application to protect the compressor from overheating shutdown or damage.

[0047] It can be understood that, in order to save device energy consumption, the target operating stage described in the present application can specifically refer to an operating stage in which the compressor has operated for a certain length of time. For example, it can specifically be a warming-up stage after the compressor has operated for a first preset length of time, or a cooling-down stage after the compressor has operated for a second preset length of time, and the like, so as to avoid collecting the discharge parameter of the compressor before the first preset length of time, at which time the compressor has just started to operate, and the discharge temperature of the compressor is within a safe preset standard range, for example, still at 0-105℃, and the like.

[0048] S102, adjusting the opening degree of the air induction valve in the target operating stage according to the discharge temperature, so as to adjust the discharge temperature of the compressor.

[0049] In an embodiment, the present application can directly adjust the opening degree of the air induction valve in the target operating stage according to the discharge temperature. For example, when the discharge temperature is greater than a preset upper temperature threshold, the air induction valve can be closed. When the discharge temperature is less than a preset lower temperature threshold, the air induction valve can be opened, and the like.

[0050] In another embodiment, before step S102, the present application can first obtain variation trend information of the discharge parameter changing over time.

[0051] The variation trend information described in the present application is used to represent the change information of the discharge parameter changing over time, which can include but is not limited to a variation trend, for example, an upward trend, a downward trend, or a stable trend; a variation rate, for example, a temperature rising rate (which can also be referred to as an upward rate), a temperature falling rate (which can also be referred to as a downward rate), and the like.

[0052] Then in step S102, the present application can adjust the opening degree of the air induction valve in the target operating stage according to the discharge temperature and the variation trend information, so as to adjust the discharge temperature of the compressor.

[0053] The air induction valve involved in the present application refers to a valve configured in a household appliance, which is used to induce air into the household appliance, so as to reduce the discharge temperature of the compressor, and then protect the compressor from shutdown or damage.

[0054] In one embodiment, the target operation stage is a temperature rising stage, and the change trend information is used to indicate a change trend of the exhaust temperature over time. Specifically, when the change trend information indicates that the exhaust temperature over time is in an upward trend, and the exhaust temperature exceeds a first threshold, the present application can increase the opening degree of the induced draft valve to a preset valve opening degree (e.g., a preset opening degree 1, etc.). Further, the exhaust temperature of the compressor can continue to rise, and the present application can continuously acquire the exhaust temperature of the compressor. When the exhaust temperature rises and exceeds a second threshold, the present application can continue to increase the opening degree of the induced draft valve until a preset upper limit opening degree of the valve, e.g., continuously increase the valve opening degree according to a preset step or a preset gear, etc., to reduce the exhaust temperature of the compressor. Here, the second threshold is greater than the first threshold.

[0055] In actual applications, the first threshold and the second threshold can refer to a single preset temperature threshold, or any temperature threshold in a preset temperature threshold range, etc., which are not limited by the present application. For example, the first threshold can be any preset value in 60-105°C, and the second threshold can be any preset value in 70-110°C, etc.

[0056] In another embodiment, the target operation stage is a temperature falling stage, and the change trend information is used to indicate a change trend of the exhaust temperature over time. Specifically, when the change trend information indicates that the exhaust temperature over time is in a downward trend, and the exhaust temperature exceeds a first threshold, the present application can reduce the opening degree of the induced draft valve to maintain the exhaust temperature of the compressor within a preset standard range, e.g., within a preset safe operation range of 60-105°C, etc.

[0057] In another embodiment, the target operation stage is a temperature rising stage, and the change trend information is used to indicate a change rate of the exhaust temperature over time. Specifically, when the exhaust temperature exceeds a first threshold, the present application can increase the opening degree of the induced draft valve to a preset valve opening degree (e.g., a preset opening degree 1, etc.). Further, the present application can continuously acquire the exhaust parameters of the compressor, and analyze to obtain change trend information of the exhaust parameters over time, which is specifically used to indicate a rising rate of the exhaust temperature over time. When the rising rate exceeds a first speed, and the exhaust temperature exceeds a first threshold, the present application can continue to increase the opening degree of the induced draft valve until a preset upper limit opening degree, e.g., continuously increase the valve opening degree according to a preset step or a preset gear, etc., to reduce the exhaust temperature of the compressor.

[0058] In yet another embodiment, the target operation stage is a temperature decreasing stage, and the change trend information is used to indicate a change rate of the exhaust temperature over time, and the present application can be used to indicate a temperature decreasing rate of the exhaust temperature over time. Specifically, when the temperature decreasing rate indicated by the change trend information exceeds a second rate, and the exhaust temperature is lower than a first threshold, the present application can reduce the opening of the induced draft valve, for example, continuously reduce the valve opening according to a preset reducing step, or reduce the valve opening according to a preset level, etc., to maintain the exhaust temperature of the compressor within a preset standard range.

[0059] In yet another embodiment, the target operation stage is a temperature increasing stage, and the change trend information is used to indicate a change trend of the exhaust pressure over time. Specifically, when the exhaust temperature exceeds a first threshold, the present application can increase the opening of the induced draft valve to a preset valve opening (for example, a preset opening 1, etc.). Further, the present application can acquire the change trend information, and when the change trend information is used to indicate that the exhaust pressure over time presents an increasing trend, and the exhaust temperature exceeds the first threshold, the present application can continue to increase the opening of the induced draft valve until a preset upper limit opening, for example, continuously increase the valve opening according to a preset step, or increase the valve opening according to a preset level, etc., to reduce the exhaust temperature of the compressor.

[0060] In yet another embodiment, the target operation stage is a temperature decreasing stage, and the change trend information is used to indicate a change trend of the exhaust pressure over time. Specifically, when the change trend information is used to indicate that the exhaust pressure over time presents a decreasing trend or a stable trend, and the exhaust temperature exceeds a first threshold, the present application can reduce the opening of the induced draft valve, for example, continuously reduce the valve opening according to a preset reducing step, or reduce the valve opening according to a preset level, etc., to maintain the exhaust temperature of the compressor within a preset standard range.

[0061] It should be noted that in addition to the above embodiments, the present application can also adjust the opening of the induced draft valve according to other exhaust parameters and their change trend information, so as to achieve the purpose of adjusting the exhaust temperature of the compressor. For example, with reference to the above embodiments of the change rate of the exhaust temperature and the adjustment of the valve opening according to the exhaust temperature, the present application can adjust the valve opening according to the change rate of the exhaust pressure (for example, the pressure increasing rate or the pressure decreasing rate) and the exhaust temperature. Alternatively, for example, the present application can adjust the opening of the induced draft valve according to the exhaust temperature and the current exhaust time, and specifically, when the exhaust temperature exceeds a first threshold, and the current exhaust time exceeds a first preset time (reflecting long-time operation of the compressor, etc.), the opening of the induced draft valve can be gradually increased to reduce the exhaust temperature of the compressor, etc., and the present application is not limited thereto.

[0062] For the convenience of understanding the technical solutions provided by the embodiments of the present application, the following refers to Figure 2 and Figure 3 respectively taking the change trend and the change rate of the exhaust temperature as examples, how to adjust the exhaust temperature of the compressor by controlling the opening of the air guide valve is introduced.

[0063] Please refer to Figure 2 is a flowchart of another control method of the exhaust temperature of the compressor provided by the embodiments of the present application. As shown in the method comprises the following implementation steps: Figure 2

[0064] S201, when the compressor is started to run, the exhaust temperature of the compressor is acquired.

[0065] After the household appliance is started (for example, the drying mode of the clothes dryer is started), the compressor runs, and the present application can collect and acquire the exhaust temperature of the compressor.

[0066] For example, taking the household appliance as the clothes dryer, please refer to Figure 4 showing a back view of the clothes dryer. As shown in the clothes dryer, the compressor is placed at the position corresponding to 401, and 402 represents the air guide valve. The clothes dryer described in the figure also includes other components, such as the condenser pipe, the evaporator, and the drum, which are not described here. Figure 4

[0067] S202, when the exhaust temperature exceeds the first threshold T1, the opening of the air guide valve is increased to a preset valve opening (which can also be called the first opening, opening 1).

[0068] The first threshold of the present application can also be called the early warning temperature T1, which can be a lower limit value or any numerical value of a preset first threshold range (for example, 60-105℃), such as 60℃. The first threshold can also represent a preset first threshold range (for example, 60-105℃), and specifically when the exhaust temperature is in the first threshold range, the opening of the air guide valve can be increased to opening 1.

[0069] S203, the exhaust temperature of the compressor is continuously acquired, and it is analyzed that the exhaust temperature increases with time.

[0070] S204, it is judged whether the target exhaust temperature of the compressor exceeds the second threshold T2, and the sampling time of the target exhaust temperature is after the sampling time of the exhaust temperature.

[0071] ​​The application can continue to monitor the exhaust temperature of the compressor in real time. If the exhaust temperature of the compressor continues to rise, when the target exhaust temperature of the compressor reaches / exceeds the second threshold T2, the application can continue to perform step S205; otherwise, step S206 is continued.

[0072] In practical applications, the second threshold can also be a lower limit value of a preset second threshold range (for example, 70-110°C) or any numerical value, such as 70°C, and the like. The second threshold can also represent a preset second threshold range (for example, 70-110°C). Specifically, when the exhaust temperature is in the second threshold range, the application performs step S205; otherwise, step S206 is performed.

[0073] S205, continue to increase the opening of the induced draft valve.

[0074] The application can increase the opening of the induced draft valve until a preset upper limit opening after detecting that the exhaust temperature shows an upward trend over time and the exhaust temperature of the compressor reaches / exceeds T2, so as to reduce the exhaust temperature of the compressor.

[0075] S206, determine whether the exhaust temperature of the compressor is in a preset standard range.

[0076] The application can continue to monitor the exhaust temperature of the compressor. If the exhaust temperature of the compressor starts to decrease, that is, the compressor is in a cooling stage, it is determined whether the exhaust temperature of the compressor is in a preset standard range. If yes, step S209 is continued; otherwise, step S207 is continued. The preset standard range is a safe operation range defined by the system. The lower limit value of the preset standard range is greater than or equal to the first threshold, preferably the first threshold. For example, the preset standard range is T160-105°C.

[0077] S207, determine whether the exhaust temperature of the compressor decreases to a third threshold, which is greater than the first threshold.

[0078] If it is determined that the exhaust temperature of the compressor does not maintain / in the preset standard range, it is determined whether the exhaust temperature of the compressor decreases to a third threshold T3, which is greater than the first threshold T2. If yes, step S208 is continued; otherwise, step S209 is performed.

[0079] S208, reduce the opening of the induced draft valve to maintain the exhaust temperature of the compressor in the preset standard range.

[0080] When the exhaust temperature of the compressor is detected to decrease but not below the first threshold value, the opening degree of the air guide valve can be reduced, and steps S207-S208 can be executed in a loop until the exhaust temperature of the compressor is maintained within the preset standard range.

[0081] S209, determining the opening degree of the air guide valve.

[0082] When the exhaust temperature of the compressor is maintained within the preset standard range, the opening degree of the air guide valve at this time can be sent to the user for confirmation, for example, displayed in the form of a short message, text, picture or subtitle on the display interface of the household appliance for user confirmation.

[0083] Please see Figure 3 is a flowchart of another control method of the exhaust temperature of the compressor provided by the embodiment of the present application. As shown in the method comprises the following implementation steps: Figure 3

[0084] S301, when the compressor is started to operate, the exhaust temperature of the compressor is acquired.

[0085] After the household appliance is started (for example, the drying mode of the clothes dryer is started), the compressor operates, and the exhaust temperature of the compressor can be acquired.

[0086] S302, when the exhaust temperature exceeds the first threshold value T1, the opening degree of the air guide valve is increased to a preset valve opening degree (also referred to as the first opening degree, opening degree 1).

[0087] The first threshold value can also be referred to as the early warning temperature T1, which can be a lower limit value of a preset first threshold value range (for example, 60-105℃) or any numerical value, for example, 60℃. The first threshold value can also represent a preset first threshold value range (for example, 60-105℃), and specifically when the exhaust temperature is within the first threshold value range, the opening degree of the air guide valve can be increased to opening degree 1.

[0088] S303, the exhaust temperature of the compressor is continuously acquired, and the temperature rising rate of the exhaust temperature with time is analyzed.

[0089] S304, whether the temperature rising rate exceeds the first rate K1 is judged.

[0090] The exhaust temperature of the compressor can be continuously monitored in real time, and if the exhaust temperature of the compressor continues to rise (i.e., the temperature rises) and the temperature rising rate exceeds the first rate K1, step S305 can be continuously executed; otherwise, step S306 can be continuously executed.

[0091] ​The first rate is a system self-defined setting, which can be a single preset rate threshold, or any rate value in a preset first rate range, for example, any value in 0.1℃ / min-5℃ / min. The first rate can also represent a preset first rate range, and specifically, the application can determine whether the temperature increasing rate is in the first rate range, and if yes, step S305 is executed; otherwise, step S306 is executed.

[0092] S305, continue to increase the opening degree of the air guide valve.

[0093] The application can continue to increase the opening degree of the air guide valve until a preset upper limit opening degree, so as to reduce the exhaust temperature of the compressor.

[0094] S306, determine whether the exhaust temperature of the compressor is in a preset standard range.

[0095] The application can continuously monitor the exhaust temperature of the compressor, and if the exhaust temperature of the compressor starts to decrease, that is, the compressor is in a cooling stage, it is determined whether the exhaust temperature of the compressor is in a preset standard range. If yes, step S309 is continuously executed; otherwise, step S307 is continuously executed. The preset standard range is a system self-defined safe operation range, and the lower limit value of the preset standard range is greater than or equal to the first threshold value, preferably the first threshold value, for example, the preset standard range is T160-105℃.

[0096] S307, determine whether the cooling rate of the compressor exceeds a second rate K2, and whether the exhaust temperature of the compressor is lower than the first threshold value.

[0097] The application can further monitor and acquire the cooling rate of the compressor, and determine whether the cooling rate exceeds the second rate and whether the exhaust temperature of the compressor is lower than the first threshold value. If yes, step S308 is continuously executed; otherwise, step S309 is executed.

[0098] The introduction of the second rate can refer to the related introduction of the first rate described above, which is not repeated here. The first rate and the second rate can be the same or different, which is not limited by the application.

[0099] S308, reduce the opening degree of the air guide valve to maintain the exhaust temperature of the compressor in the preset standard range.

[0100] When the application detects that the exhaust temperature of the compressor decreases, the cooling rate is lower than the second rate, or the exhaust temperature of the compressor exceeds the first threshold value, the opening degree of the air guide valve can be reduced, and steps S307-S308 are cyclically executed until the exhaust temperature of the compressor is maintained in the preset standard range.

[0101] S309, determining the opening degree of the air guide valve.

[0102] The application can send the opening degree of the air guide valve to the user for confirmation when the exhaust temperature of the compressor is maintained within the preset standard range, for example, in the form of a short message, text, picture or subtitle, and displayed on the display interface of the household appliance for the user to confirm.
