[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0044] Combination Figure 1 and Figure 2 As shown, in some embodiments, a refrigeration device 1 is provided, comprising: an evaporator 10 , a first heating wire 201 and a second heating wire 202 .
[0045] The first heating wire 201 is disposed on the circumference of the evaporator 10. The second heating wire 202 is disposed on the circumference of the evaporator 10, and the first heating wire 201 and the second heating wire 202 are connected in parallel.
[0046] In the embodiment of the present disclosure, a heating wire is arranged around the evaporator 10 to heat the evaporator 10 and achieve a defrosting effect. The first heating wire 201 and the second heating wire 202 are arranged to heat the evaporator 10 at the same time, thereby enhancing the defrosting effect of the evaporator 10 and reducing the influence of frosting of the evaporator 10 on the refrigeration effect.
[0047] Furthermore, the first heating wire 201 and the second heating wire 202 are arranged in parallel, so that the first heating wire 201 and the second heating wire 202 can work independently. In the related art, multiple heating wires work at the same time, which increases the power consumption of the refrigeration device 1, and it is also impossible to individually defrost the severely frosted part of the evaporator 10. In the embodiment of the present disclosure, when the amount of frost on the evaporator 10 is small or only part of the frost is formed, only one heating wire is turned on for heating, which can achieve defrosting and reduce the power consumption of the refrigeration device 1. Furthermore, by having multiple heating wires work alternately, it is possible to avoid a single heating wire being turned on for a long time, thereby extending the service life of the heating wire.
[0048] Optionally, the first heating wire 201 and the second heating wire 202 located on the same side of the evaporator 10 are spaced apart.
[0049] In the disclosed embodiment, a heating wire is arranged on the peripheral side of the evaporator 10, so that the evaporator 10 can be heated to achieve a defrosting effect. The first heating wire 201 and the second heating wire 202 are arranged to heat the evaporator 10 at the same time, thereby enhancing the defrosting effect on the evaporator 10 and reducing the influence of the frosting of the evaporator 10 on the refrigeration effect. Furthermore, the first heating wire 201 and the second heating wire 202 are arranged at intervals, so that the heat of the heating wire can be less concentrated in a certain place of the evaporator 10, so that the defrosting effect is more uniform, and the influence of the frosting of the evaporator 10 on the refrigeration effect is further reduced.
[0050] Optionally, the first heating wire 201 is wound around the evaporator 10 ; the second heating wire 202 is wound around the evaporator 10 .
[0051] In the disclosed embodiment, a heating wire is arranged on the peripheral side of the evaporator 10, so that the evaporator 10 can be heated to achieve a defrosting effect. The first heating wire 201 and the second heating wire 202 are arranged to heat the evaporator 10, which enhances the defrosting effect on the evaporator 10 and reduces the influence of frosting on the evaporator 10 on the refrigeration effect. Furthermore, the first heating wire 201 and the second heating wire 202 are arranged around the peripheral side of the evaporator 10, so that the heat generated by the first heating wire 201 and the second heating wire 202 can be more evenly transferred to the evaporator 10, which can reduce the situation where the heat of the heating wire is concentrated in a certain place of the evaporator 10, so that the defrosting effect is more uniform, thereby achieving defrosting of the evaporator 10 as a whole, and further reducing the influence of frosting on the evaporator 10 on the refrigeration effect.
[0052] Optionally, the power of the first heating wire 201 is greater than or equal to the power of the second heating wire 202 .
[0053] In the embodiment of the present disclosure, the power of the first heating wire 201 and the second heating wire 202 are different. When the amount of frost at different locations of the evaporator 10 is different, heating can be performed by using the power of different heating wires. In the related art, the power of multiple heating wires is the same, and it is impossible to defrost locations with different amounts of frost by using heating wires of different powers. By setting heating wires of different powers in the embodiment of the present disclosure, when the amount of frost at different locations of the evaporator 10 is different, by turning on heating wires of different powers, defrosting can be achieved and the power consumption of the refrigeration device 1 can be reduced.
[0054] Combination Figure 3 As shown, optionally, the evaporator 10 includes fins 101 , and the distribution density of the first heating wires 201 and the second heating wires 202 are both positively correlated with the density of the fins 101 .
[0055] In the disclosed embodiment, the evaporator 10 is provided with fins 101 for expanding the heat exchange area. The density of the fins 101 at different positions is different, which makes it easier for the position with high density to frost. The distribution density of the first heating wire 201 and the second heating wire 202 is positively correlated with the density of the fin 101. In this way, the first heating wire 201 and the second heating wire 202 can provide more heat at the position with large frost, enhance the defrosting effect of the evaporator 10, and reduce the influence of the frosting of the evaporator 10 on the refrigeration effect. In addition, at the position with small frost, the distribution density of the first heating wire 201 and the second heating wire 202 is small, which realizes defrosting while further reducing the power consumption of the refrigeration device 1.
[0056] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, optionally, the refrigeration device 1 further includes a third heating wire 203 .
[0057] The third heating wire 203 is disposed on the peripheral side of the evaporator 10. The first heating wire 201, the second heating wire 202, and the third heating wire 203 are connected in parallel, and the heating powers of the first heating wire 201, the second heating wire 202, and the third heating wire 203 are all different.
[0058] In the embodiment of the present disclosure, the third heating wire 203 is provided, which can further improve the defrosting effect on the evaporator 10. The first heating wire 201, the second heating wire 202, and the third heating wire 203 are arranged in parallel with each other, so that the first heating wire 201, the second heating wire 202 and the third heating wire 203 can work independently. In the related art, multiple heating wires work at the same time, which increases the power consumption of the refrigeration device 1, and it is also impossible to individually defrost the severely frosted part of the evaporator 10. In the embodiment of the present disclosure, when the amount of frost on the evaporator 10 is small or only part of the frost is formed, only one or part of the heating wires are turned on for heating, which can achieve defrosting and reduce the power consumption of the refrigeration device 1. In addition, by having multiple heating wires work alternately, it is possible to avoid a single heating wire being turned on for a long time, thereby extending the service life of the heating wires.
[0059] Furthermore, the heating powers of the first heating wire 201, the second heating wire 202, and the third heating wire 203 are all different. When the amount of frost at different locations of the evaporator 10 is different, heating can be performed by selecting heating wires of different powers. In the related art, the power of multiple heating wires is the same, which makes it impossible to defrost locations with different amounts of frost by selecting heating wires of different powers, and the defrosting effect is poor. The embodiment of the present disclosure sets heating wires of different powers, and when the amount of frost at different locations of the evaporator 10 is different, the power of the heating wire is reduced, which can not only achieve defrosting, but also reduce the power consumption of the refrigeration device 1.
[0060] Combination Figure 3 As shown, optionally, the refrigeration device 1 further includes a water receiving tray 501 , a water pump 502 and a spray head 503 .
[0061] The water receiving tray 501 is disposed at the bottom of the evaporator 10 for collecting defrost water. One end of the water pump 502 is connected to the water receiving tray 501. The spray head 503 is connected to the other end of the water pump 502, and the spray head 503 is located at the top of the evaporator 10. The water pump 502 is used to spray the defrost water in the water receiving tray 501 to the evaporator 10 through the spray head 503.
[0062] In the disclosed embodiment, the water receiving tray 501 collects and stores the defrost water generated by the evaporator 10, and the defrost water in the water receiving tray 501 is sprayed to the evaporator 10 through the provided water pump 502 and the spray head 503, so as to defrost the evaporator 10. In this way, the defrost efficiency can be improved, and the defrost water can be recycled and does not need to be frequently replaced, so the waste of water resources can be avoided.
[0063] Optionally, the water receiving tray 501 is provided with an overflow port 504 .
[0064] In the disclosed embodiment, water in the water receiving tray 501 can overflow through the overflow port 504 , and the overflowed water can be discharged for evaporation, thereby preventing excessive water in the water receiving tray 501 from overflowing into the compartment outside the evaporation chamber 301 .
[0065] Optionally, the refrigeration device 1 further comprises a temperature sensor. The temperature sensor is disposed on the surface of the evaporator 10 and is used to detect the temperature of the evaporator 10.
[0066] In the embodiment of the present disclosure, the temperature of the evaporator 10 is detected by the temperature sensor, and the amount of frost on the evaporator 10 can be obtained, and then the number of heating wires to be turned on can be selected according to the amount of frost. This reduces the situation where the defrosting effect is poor due to insufficient heat provided by the heating wires, and also reduces the situation where too many heating wires are turned on and the power consumption of the refrigeration device 1 increases. In this way, the temperature sensor can not only improve the defrosting effect, but also reduce the power consumption of the refrigeration device 1.
[0067] Optionally, there are multiple temperature sensors, which are arranged on the surface of the evaporator 10 at intervals.
[0068] In the disclosed embodiment, the temperature sensors arranged at intervals can detect the temperature at different positions of the evaporator 10, and thus obtain the amount of frost at different positions of the evaporator 10. According to the amount of frost, the heating wire corresponding to the position where the frost is formed is selected to be turned on. In the case where only part of the evaporator 10 is frosted, only one or part of the heating wires are turned on for heating, which can achieve defrosting and reduce the power consumption of the refrigeration device 1. In addition, by having multiple heating wires working alternately, it is possible to avoid a single heating wire being turned on for a long time, thereby extending the service life of the heating wire.
[0069] Combination Figure 2 As shown, optionally, the refrigeration device 1 further includes a box body 30 , a return air duct 401 and a return air fan 402 .
[0070] The housing 30 includes an evaporation chamber 301 and a refrigeration chamber 302. The evaporator 10 is provided with the evaporation chamber 301, and the refrigeration chamber 302 includes a return air port. A return air duct 401 is provided in the housing 30, and both ends of the return air duct 401 are respectively connected to the return air port and the evaporation chamber 301. A return air fan 402 is provided in the return air duct 401, and is used to send air in the refrigeration chamber 302 into the evaporation chamber 301.
[0071] In the disclosed embodiment, the evaporation bin 301 and the refrigeration compartment 302 are connected by providing a return air port and a return air duct 401. When the evaporator 10 needs to be defrosted, the return air fan 402 is turned on, and the air in the refrigeration compartment 302 is sent to the evaporation bin 301 through the return air duct 401. The air in the refrigeration compartment 302 contains a certain amount of heat, which can be used to accelerate the defrosting process and improve the defrosting efficiency. By providing the return air duct 401 and the return air fan 402, the gas flow in the evaporation bin 301 can be improved, thereby achieving the purpose of disturbing the gas in the evaporation bin 301, thereby improving the uniformity of the temperature in different areas of the evaporation bin 301, and achieving the effect of improving the defrosting effect.
[0072] Optionally, the box body 30 further includes a water collecting tank and a water pipe.
[0073] The water collecting tank is located at the bottom of the refrigerated space and is used to collect condensed water in the refrigerated space. One end of the water guide pipe is connected to the drain outlet of the water collecting tank, and the other end is connected to the water receiving tray 501 to guide the water in the water collecting tank into the water receiving tray 501.
[0074] In the embodiment of the present disclosure, the condensed water in the refrigerated space is introduced into the water receiving pan 501 by setting a water collecting tank and a water guide pipe, so that when the water receiving pan 501 does not store enough defrosting water, the water pump 502 and the nozzle 503 can still spray defrost on the evaporator 10, thereby improving the defrosting effect. In addition, the use of condensed water for defrosting can realize the recycling of condensed water, and there is no need to set a passage in the refrigeration device 1 to remove the condensed water.
[0075] In some embodiments, a control method for the above refrigeration device 1 is provided, comprising:
[0076] Check whether the temperature of the evaporator 10 reaches the defrosting condition.
[0077] When the temperature of the evaporator 10 reaches the defrosting condition, the ambient temperature and humidity are detected.
[0078] When the ambient temperature is higher than 15°C or the ambient humidity is higher than 65%, the first heating wire 201 is turned on. When the ambient temperature is higher than 25°C or the ambient humidity is higher than 75%, the first heating wire 201 and the second heating wire 202 are turned on. When the ambient temperature is higher than 35°C or the ambient humidity is higher than 85%, all the heating wires are turned on.
[0079] In the disclosed embodiment, the amount of frost on the evaporator 10 is determined based on the detected ambient temperature and ambient humidity, and the number of heating wires to be turned on is then selected, which can both achieve defrosting and reduce the power consumption of the refrigeration device 1. In addition, by having multiple heating wires working alternately, it is possible to avoid a single heating wire being turned on for a long time, thereby extending the service life of the heating wires.
[0080] Optionally, if the user opens the door more than 10 times within 12 hours or the door opening time is longer than 60 seconds within 12 hours, turn on the first heating wire 201. If the user opens the door more than 20 times within 12 hours or the door opening time is longer than 120 seconds within 12 hours, turn on the first heating wire 201 and the second heating wire 202. If the user opens the door more than 30 times within 12 hours or the door opening time is longer than 180 seconds within 12 hours, turn on all heating wires.
[0081] In the disclosed embodiment, the amount of frost on the evaporator 10 is determined based on the number of times the user opens the door and the duration of the door opening, and then the number of heating wires to be turned on is selected, which can not only achieve defrosting, but also reduce the power consumption of the refrigeration device 1. In addition, by having multiple heating wires working alternately, it is possible to avoid a single heating wire being turned on for a long time, thereby extending the service life of the heating wires.
[0082] Optionally, during the refrigeration process, if the temperature drop rate of the refrigerating compartment 302 is less than 1°C / 5min, the first heating wire 201 is turned on. If the temperature drop rate of the refrigerating compartment 302 is less than 1°C / 10min, the first heating wire 201 and the second heating wire 202 are turned on. If the temperature drop rate of the refrigerating compartment 302 is less than 1°C / 15min, all the heating wires are turned on.
[0083] In the embodiment of the present disclosure, the amount of frost on the evaporator 10 is determined according to the temperature drop rate of the refrigerated compartment 302, and the number of heating wires to be turned on is selected, which can not only achieve defrosting, but also reduce the power consumption of the refrigeration device 1. In addition, by having multiple heating wires working alternately, it is possible to avoid a single heating wire being turned on for a long time, thereby extending the service life of the heating wires.
