Description

Refrigerator and temperature control method thereof

The present invention relates to a cooling device and a method thereof, and more particularly to a refrigerator that utilizes a difference in wind speed between two fans for airflow adjustment and a temperature control method thereof.

Refrigerators are an indispensable household appliance for the general public. From the early upper freezer refrigerators to the next-stage frozen refrigerators, the pursuit of comfort in the use of refrigerators is shown in the improvement of people's living standards. Since the freezer compartment and the evaporator of the upper freezer are disposed above the body, there is an upper refrigerator. The upper freezer refrigerator is designed to be more fluid-compatible and is conducive to natural convection-like gas circulation. The above freezer refrigerator can reduce the load of the circulating fan. However, the statistics show that since the number of times the door is opened in the refrigerator is much higher than the number of doors used in the freezer, and the use of the refrigerator requires bending over to find the item, ergonomically, such use often results in the user's use. Inconvenience, thereby reducing the user's comfort in use.

In addition to the above-mentioned problems regarding comfort, the items stored in the freezer of the upper freezer are often foods that are odorous, such as fish, and because the freezer of the upper freezer is located above the refrigerator, the odor of the freezer It is easy to enter the refrigerating compartment located below the freezer with cold air. Furthermore, in general, the food stored in the freezer is cold. It is usually quite hard after freezing, so when the user explores the food in the freezer above the cold room, the dropped food tends to hurt the user's foot as soon as the food falls off the freezer.

In view of the above problems with respect to the upper freezer refrigerator, the prior art proposes a lower freezer compartment in which the freezer compartment is disposed below the refrigerator. The structure of the lower freezer refrigerator is similar to that of the upper freezer refrigerator except that the configuration of the freezer compartment is different. Please refer to FIG. 1 , which is a side view of a conventional lower freezer. The lower freezer refrigerator 500 includes a housing 510, a circulation fan 520, a mechanical valve 530, and an evaporator 540. The housing 510 defines a refrigerating chamber 512, a freezing chamber 514, and a circulation path 516. The refrigerating compartment 512 is in communication with the freezing compartment 514 via a circulation path 516. The refrigerating compartment 512 is located above the freezing compartment 514. The mechanical valve 530 is located in the lower freezer compartment 500 and is located upstream of the inlet of the circulating gas into the refrigerating compartment 512. Through the opening and closing of the mechanical valve 530, conventional techniques can open or prevent airflow into the refrigerating chamber 512. The circulation fan 520 is located between the mechanical valve 530 and the evaporator 540. Therefore, when the mechanical valve 530 is opened, the gas in the lower freezing refrigerator 500 is driven by the circulation fan 520, and the self-evaporator 540 enters the refrigerating chamber 512 via the mechanical valve 530.

However, the design of the lower freezer 500 described above has the following problems. First, since the number of opening and closing of the mechanical valve 530 is not frequent under normal use conditions, the water vapor in the gas circulating in the lower freezer 500 tends to solidify on the mechanical valve 530, thereby causing Failure of mechanical valve 530.

Next, when the chilling refrigerator 500 performs defrosting, since the hot air has a floating characteristic, and the circulation path 516 easily generates a chimney effect, the heat generated by the defrosting easily flows toward the refrigerating chamber 512. At this time, if the mechanical valve 530 is mechanically When the tolerance relationship is made and cannot be completely closed, part of the hot air is easily leaked into the refrigerating chamber 512 via the mechanical valve 530. When the hot air enters the refrigerating chamber 512 and causes the temperature of the refrigerating chamber 512 to rise, the temperature sensor (not shown) coupled to the mechanical valve determines that the temperature of the refrigerating chamber 512 is too high, so that the mechanical valve 530 is made. Open. As a result, a larger amount of hot air approaches the refrigerating chamber 512 via the mechanical valve 530, and the temperature of the refrigerating chamber 512 rises sharply. As a result, the food stored in the refrigerating compartment 512 is prone to spoilage.

In view of the above problems, the present invention provides a refrigerator and a temperature control method thereof, thereby replacing a conventional refrigerator having a mechanical valve and a control method therefor.

Preferably, in the embodiment, the refrigerator 100 further includes a freezing chamber temperature sensor 162 and a refrigerating chamber temperature sensor 164.

Through the above-described freezing chamber temperature sensor 162 and the refrigerating chamber temperature sensor 164, the controller 150 determines the temperature of the freezing chamber 111 and the temperature of the refrigerating chamber 112 according to the freezing chamber temperature signal and the refrigerating chamber temperature signal. Thereafter, the controller 150 controls the refrigerating gas fan 130 and the refrigerating according to the temperature of the freezing chamber 111 and the temperature of the refrigerating chamber 112. The rotational speed of the gas fan 140. The manner of control of the controller 150 will be described in detail below.

In this embodiment, the controller 150 includes a storage module 152 and a control module 154. The storage module 152 stores a control program. The control module 154 is electrically connected to the storage module 152, the compressor 122, the refrigerating gas fan 130, and the refrigerating gas fan 140. The control module 154 accesses the storage module 152 and controls the compressor 122, the refrigerating gas fan 130, and the refrigerating gas fan 140 in accordance with control laws established by the control program. It should be noted that although the controller 150 is composed of a control module 154 and a storage module 152 in this embodiment, such an architecture is not intended to limit the present invention. In other implementations in accordance with the present invention, controller 150 can also be a single chip having a programmable function or an electronic circuit having a hardware logic circuit. The manner of control of the controller 150 will be described in detail below.

FIG. 3 is a flow chart showing the control law of the control program stored in the storage module 152 of the present invention. First, as shown in step S1000, the refrigerator 100 is started. After the refrigerator 100 is started, the control module 154 reads the control program in the storage module 152 and operates according to the control program of the control program, wherein the control system has preset a critical temperature of the freezing chamber, a first refrigeration The chamber critical temperature and a second refrigerating chamber critical temperature, and the freezing chamber critical temperature < the first refrigerating chamber critical temperature < the second refrigerating chamber critical temperature.

Thereafter, as shown in step S1002, the control module 154 determines whether the temperature of the freezing chamber 111 is higher than the freezing chamber critical temperature. If the temperature of the freezing chamber 111 is higher than the critical temperature of the freezing chamber, the control module 154 activates the compressor 122 as shown in step S1004. Next, as shown in step S1006, the control module 154 determines whether the temperature of the refrigerating chamber 112 is higher than the critical temperature of the first refrigerating chamber. If the temperature of the refrigerating chamber 112 is higher than the critical temperature of the first refrigerating chamber, the control module 154 drives the refrigerating gas fan 130 and the refrigerating gas fan 140 as shown in step S1008. Further, the refrigerating gas fan 130 and the refrigerating gas fan 140 are operated at full speed. As a result, the gas system circulating in the refrigerator 100 passes through the evaporator 126 via the freezing gas fan 130 and the refrigerating gas fan 140, and enters the freezing chamber through the freezing chamber first flow path 113 and the refrigerating chamber first flow path 115, respectively. 111 and the refrigerating chamber 112 are configured to lower the temperature of the freezing chamber 111 and the temperature of the refrigerating chamber 112 to a critical temperature of the freezer and a critical temperature of the first refrigerating chamber, respectively.

If the temperature of the refrigerating chamber 112 is lower than or equal to the critical temperature of the first refrigerating chamber, as shown in step S1010, the control module 154 controls the refrigerating gas fan 130 and the refrigerating gas fan 140 according to the control program, wherein the refrigerating gas fan 130 The operating power is higher than the operating power of the refrigerating gas fan 140. For example, in the present embodiment, the refrigerating gas fan 130 is operated at full power, and the refrigerating gas fan 140 is operated at half power. As such, the gas system circulating within the refrigerator 100 passes through the evaporator 126 and enters the freezing chamber 111 via the freezer first flow passage 113 to lower the freezing chamber 111 below the critical temperature of the freezer. Since the refrigerating gas fan 140 is operated at half power, the refrigerating gas fan 140 can prevent the gas located in the refrigerating chamber 112 from being extracted by the refrigerating gas fan 130 to the freezing chamber 111.

In step S1002, if the temperature of the freezing chamber 111 is lower than or equal to the freezing chamber critical temperature, the control module 154 turns off the compressor 122 as shown in step S1012. Next, as shown in step S1014, the control module 154 determines whether the temperature of the refrigerating chamber is higher than the critical temperature of the first refrigerating chamber. If the temperature of the refrigerating chamber is lower than or equal to the critical temperature of the first refrigerating chamber, the freezing gas fan 130 and the refrigerating gas fan 140 are turned off as shown in step S1016.

In step S1014, if the temperature of the refrigerating chamber is higher than the critical temperature of the first refrigerating chamber, as shown in step S1018, it is further determined whether the temperature of the refrigerating chamber is higher than the critical temperature of the second refrigerating chamber. If the temperature of the refrigerating chamber is lower than or equal to the critical temperature of the second refrigerating chamber At the same time, as shown in step S1020, the refrigerating gas fan 130 and the refrigerating gas fan 140 are activated, wherein the operating power of the refrigerating gas fan 130 is lower than the operating power of the refrigerating gas fan 140. In the present embodiment, the refrigerating gas fan 130 is operated at half power, and the refrigerating gas fan 140 is operated at full power. As a result, the gas system circulating in the refrigerator 100 passes through the evaporator 126 and enters the refrigerating chamber 112 via the refrigerating chamber first flow path 115. Since the refrigerating gas fan 130 is operated at half power, the refrigerating gas fan 130 can prevent the gas located in the freezing chamber 111 from being drawn into the refrigerating chamber 112 by the refrigerating gas fan 140. It should be noted that since the temperature of the refrigerating chamber 112 is generally higher than the solidification temperature of the water vapor, when the control module 154 performs the step S1020 according to the control law, the gas passing through the evaporator 126 defrosts the evaporator 126. The effect. Therefore, step S1020 can also be regarded as a step of defrosting a pair of evaporators 126.

In step S1018, if the temperature of the refrigerating chamber is higher than the critical temperature of the second refrigerating chamber, as shown in step S1022, the refrigerating gas fan 130 is turned off and the refrigerating gas fan 140 is activated. As such, the gas system located in the freezing chamber 111 is drawn to the refrigerating chamber 112 by the refrigerating gas fan 140 to lower the temperature of the refrigerating chamber 112.

It is worth mentioning that, in addition to performing the defrosting step through the control rules executed by the control module 154 described above, the present invention can further store a defrosting program in the storage module 152 so that the control module 154 can be Perform a defrost rule by reading the defrost program. In another embodiment of the present invention, the control module 154 can receive a control signal to cause the control module 154 to execute a defrosting rule, wherein the control signal is controlled by, for example, a refrigerator 100. The button is issued. In this way, the user can directly drive the control module to perform the defrosting step described in step S1020 by pressing the control button.

In summary, since the present invention separately uses a refrigerating gas fan and a refrigerating gas The fan is disposed in the first flow path of the freezing chamber and the first flow path of the refrigerating chamber, and since the controller can control the rotation speed of the refrigerating gas fan and the refrigerating gas fan according to controlling the temperature of the freezing chamber and the temperature of the refrigerating chamber, In view of the technology, the present invention can achieve the efficacy of a mechanical valve equivalent to the prior art by adjusting the wind pressure generated by the refrigerating gas fan and the refrigerating gas fan. Further, since the refrigerating gas fan and the refrigerating gas fan of the present invention are continuously rotated during operation, water vapor is less likely to solidify on the refrigerating gas fan and the refrigerating gas fan of the present invention than in the prior art. Therefore, the present invention can replace the design of the conventional mechanical valve and has the advantage of being more durable.
