Description

Technical Field

[0001] The present application relates to the technical field of refrigeration systems, and in particular to a refrigerator evaporator defrosting control method, device, readable storage medium and refrigerator. Background Art

[0002] As an indispensable appliance in modern families, the normal operation of refrigerators is essential to keep food fresh and of good quality. However, during the operation of refrigerators, due to the temperature difference between the inside and outside, frost is easy to form on the surface of the evaporator. The accumulation of frost will not only reduce the refrigeration efficiency of the refrigerator and increase energy consumption, but also may affect the storage quality of food. Therefore, effective defrosting technology is of great significance to the performance and energy saving of refrigerators.

[0003] There are many defrosting methods in the prior art, and electric heating defrosting is one of the more common defrosting methods in refrigerators. The principle is to install an electric heating wire on the evaporator, and generate heat to melt the frost layer after power is turned on. However, this method has the disadvantages of high energy consumption, long defrosting time, and easy thermal damage to the evaporator. Natural defrosting is to stop the refrigerator from refrigerating and rely on the natural rise of the temperature inside the refrigerator to melt the frost layer. Although this method is simple, it takes a long time to defrost and is inefficient. In addition, the refrigerator cannot work normally during the defrosting process, affecting the storage of food. Hot gas bypass defrosting is to introduce the high-temperature and high-pressure refrigerant gas discharged from the compressor into the evaporator for defrosting. This method has a faster defrosting speed, but requires complex pipeline design and control, and is more expensive. Vibration defrosting can remove the double layer by vibration, but the vibration will not only produce a certain amount of noise, but also cause potential damage to the structure and components of the refrigerator due to improper parameter settings, affecting the service life of the refrigerator.

[0047] In this embodiment, a refrigerator evaporator defrosting control method is provided. Figure 2 is a flow chart of the refrigerator evaporator defrosting control method of this embodiment, which is applied to defrosting equipment such as Figure 3 As shown, the defrosting device includes a heating device 310, a vibration device 330 and a controller; the heating device 310 and the vibration device 330 are respectively arranged on the evaporator 320 of the refrigerator, and the heating device 310 and the vibration device 330 are respectively connected to the controller; the method is applicable to the controller; Figure 2 FIG. 1 is a flow chart of the refrigerator evaporator defrosting control method of this embodiment. Figure 2 As shown, the process includes the following steps:

[0048] Step S210, after the refrigerator is started, determine whether the current time is within a preset time interval.

[0049] Specifically, the time interval can be set to a fixed time, such as 7:00-22:00; or can be set by the user according to his own usage requirements, that is, the controller is dynamically set based on the setting information input by the user.

[0050] Step S220: If the current time is not within the preset time interval, the heating device 310 is started to perform electric heating and defrosting.

[0051] Specifically, the heating device 310 can be installed below or on the side of the evaporator 320, including but not limited to the use of aluminum foil heating plates, heating tubes or electric heating wires. After the heating device 310 is working, the surface temperature of the evaporator 320 is increased to achieve the purpose of melting the frost layer. The heating device 310 can quickly melt the frost layer in a short time, reduce energy consumption, and has low noise. Therefore, if the current time is not within the preset time interval, for example, not between 7:00-22:00, electric heating defrosting is enabled to avoid disturbing people resting in the room. Preferably, the heating device 310 is set at the bottom of the evaporator 320, and the frosted evaporator 320 is heated and defrosted by using the principle of rising hot air to further improve efficiency.

[0052] Step S230: If the current time is within the preset time interval, the vibration device 330 is activated to perform vibration defrosting.

[0053] Specifically, the vibration device 330 can use an ultrasonic vibration generator to reduce the damage to other devices caused by noise and strong vibration. In addition, the ultrasonic vibration generator generates high-frequency ultrasonic defrosting and defrosting vibrations, which cause high-frequency molecular motion of water droplets condensed in the refrigerator or frosted interior to dissolve into mist. These mists cannot condense and always fill the entire storage chamber, thereby preserving the freshness and humidity of food and ingredients placed in the storage chamber, extending the refrigeration and preservation effect of food and ingredients, and eliminating the trouble of manual defrosting. Since vibration defrosting has the advantage of low power consumption, vibration defrosting is enabled within a preset time interval that has less impact on users to reduce power consumption, and more humane defrosting control is achieved through the cooperation of vibration defrosting and electric heating defrosting.

[0054] The refrigerator evaporator 320 defrost control method, device, readable storage medium and refrigerator provided in the present embodiment determine whether the current time is within a preset time interval after the refrigerator is started; if the current time is not within the preset time interval, the heating device 310 provided on the evaporator 320 is started to perform electric heating defrosting; if the current time is within the preset time interval, the vibration device 330 provided on the evaporator 320 is started to perform vibration defrosting, thereby solving the problems of low defrosting efficiency, high energy consumption and great damage to refrigerator components of the refrigerator evaporator 320, optimizing the defrost control logic, and combining the two defrosting methods efficiently to take advantage of each other, thereby improving the defrosting efficiency, reducing power consumption and reducing the risk of loss to the refrigerator.

[0055] In some of the embodiments, after the refrigerator is started, determining whether the current time is within a preset time interval includes:

[0056] Step S211, after the refrigerator is started, the accumulated running time of the refrigerator compressor is obtained.

[0057] Step S212, when the accumulated running time reaches a preset first time length, it is determined whether the current time is within a preset time interval.

[0058] Specifically, the cumulative running time refers to the total running time from the time when the refrigerator compressor is first powered on or the last defrost ends to the current time. The cumulative running time can be set based on parameters such as the air conditioner model, heating efficiency, and environmental conditions. Preferably, after the refrigerator is started, if the cumulative running time of the compressor is less than 4 hours, defrosting will not be started to avoid consuming extra energy; when the cumulative running time of the compressor reaches 4 hours, defrosting will be started. Before starting defrosting, the current time will be determined, and the corresponding defrosting mode will be turned on based on the determination result at the current time.

[0059] In some of the embodiments, the defrost device further includes a first temperature measuring device connected to the controller, and the first temperature measuring device is disposed on the evaporator 320 to measure the temperature of the evaporator 320 .

[0060] Specifically, the first temperature measuring device is a temperature sensor, and the first temperature measuring device is disposed on the top of the evaporator 320 .

[0061] In some embodiments, if the current time is not within the preset time interval, after the heating device 310 is started to perform electric heating defrosting, the method further includes:

[0062] Step S240, during the electric heating defrosting process, when the temperature of the evaporator 320 collected by the first temperature measuring device reaches a preset value, or the continuous working time of the heating device 310 exceeds a preset second time length, the heating device 310 is turned off.

[0063] Specifically, electric heating defrosting is fast and the process is stable, but it will affect the temperature inside the freezer to a certain extent. Therefore, the start time of the heating device 310 is controlled to avoid long-term heating, which will affect the temperature inside the freezer and reduce excessive energy consumption.

[0064] In some of the embodiments, the defrosting device further includes a second temperature measuring device connected to the controller, and the second temperature measuring device is disposed in the freezer compartment of the refrigerator to measure the temperature inside the freezer compartment.

[0065] Wherein, if the current moment is within the preset time interval, after the vibration device 330 is started to perform vibration defrosting, the method further includes:

[0066] Step S310, during the vibration defrosting process, the temperature difference between the temperature of the evaporator 320 and the temperature inside the freezing chamber is calculated.

[0067] Step S320, when the temperature difference is within the preset temperature range, the duty cycle of the vibration control signal is calculated based on the temperature difference; when the temperature difference is higher than the preset temperature range, the duty cycle of the vibration control signal is set to 100%.

[0068] Specifically, the temperature difference ΔT between the temperature of the evaporator 320 and the temperature inside the freezer compartment is usually between 0 and 5°C, and the preset temperature range can be set to 5°C. When ΔT≤5°C, the frequency of vibration defrosting can be controlled according to the duty cycle of η=20ΔT×100%. When ΔT>5°C, the duty cycle η=100%.

[0069] Step S330 , controlling the vibration frequency of the vibration device 330 based on the duty cycle of the vibration control signal.

[0070] Specifically, vibration defrosting has little effect on the temperature inside the freezer, but vibration will also bring noise and the risk of damage to other devices, and cannot be used for a long time with high intensity. Therefore, the temperature inside the freezer is monitored in real time through a second temperature measuring device, and the vibration frequency of the vibration device 330 is controlled based on the temperature difference between the temperature of the evaporator 320 and the temperature inside the freezer, so that the vibration defrosting is more stable.

[0071] In some of the embodiments, Figure 3 As shown, the heating device 310 is disposed at the bottom of the evaporator 320, and utilizes the principle of rising hot air to heat and defrost the frosted evaporator 320, thereby improving the defrosting efficiency.

[0072] In some of the embodiments, Figure 3 As shown, the vibration device 330 is disposed at the center of the evaporator 320 , and the vibration waves generated by the vibration device 330 are transmitted to various parts of the evaporator 320 more evenly, which helps to improve the defrosting efficiency.

[0073] The present embodiment is described and illustrated below through preferred embodiments.

[0074] See also Figure 4 and Figure 5, the defrost device is arranged in the box shell 340 of the refrigerator, and the defrost device includes an electric heating wire 311, an ultrasonic vibration generator 331, a first temperature sensor 341, a second temperature sensor and a controller. The vibration generator is located at the center of the evaporator 320 to achieve the defrosting effect more quickly; the electric heating wire 311 is arranged at the bottom of the evaporator 320, and the frosted evaporator 320 is heated and defrosted by the principle of rising hot air. The first temperature sensor 341 is located at the top of the evaporator 320, and is used to collect the temperature of the evaporator 320. The second temperature sensor is located in the freezer compartment of the refrigerator, and is used to collect the temperature inside the freezer compartment. In order to avoid the problems of loud noise and easy damage to parts caused by vibration defrosting; electric heating defrosting affects the indoor temperature of the refrigerator and high energy consumption. Set the defrost control logic to effectively combine the two defrosting methods by taking advantage of their strengths and weaknesses. The specific logic control is as follows:

[0075] After the refrigerator is started, the accumulated running time of the refrigerator compressor is judged. If the accumulated running time of the refrigerator compressor does not reach 4 hours, defrosting will not be performed.

[0076] If the cumulative running time of the refrigerator compressor reaches 4 hours, it is determined whether the current time is within the interval of 7:00-22:00. If the current time is within the interval of 7:00-22:00, the vibration generator is started for vibration defrosting. At the same time, the difference ΔT between the temperature of the evaporator 320 and the temperature inside the freezer is calculated. Usually, the range of ΔT is 0-5°C, and the frequency of vibration defrosting is controlled according to the duty cycle of η=20ΔT×100%. When ΔT>5°C, η=100%.

[0077] If the cumulative running time of the refrigerator compressor reaches 4 hours, determine whether the current time is within the range of 7:00-22:00. If the time is not within the range of 7:00-22:00, start the defrost heating wire for electric heating defrosting, and exit the electric heating defrosting when the evaporator 320 reaches 8°C or the heating wire works continuously for 60 minutes.

[0078] In this preferred embodiment, the vibration defrosting has little effect on the compartment temperature and the electric heating defrosting is fast, uniform and stable; at the same time, the noise generated by the vibration defrosting at night and the high energy consumption of the electric heating defrosting during the day are avoided, so as to achieve a more effective and humanized defrosting control process.
