Description

A method and device for removing condensed water in an air-cooled refrigerator

technical field

The invention relates to the technical field of refrigeration equipment, in particular to a method and device for removing condensed water used in an air-cooled refrigerator.

Background technique

Air-cooled refrigerators can automatically defrost regularly, avoid manual defrosting by users, and improve the convenience of users, so they are welcomed by users. As shown in Figure 1, when the air-cooled refrigerator is working, due to the rotation of the fan 1, the air with a higher temperature flows from the air return port 3 of the storage compartment 2 through the surface of the evaporator 4, and exchanges heat with the evaporator 4 to cool down. , and the airflow with lower temperature flows into the storage compartment 2 through the air outlet 5, thereby reducing the temperature of the storage compartment 2; The storage compartment 2 is contacted so that the inner surface of the storage compartment 2 does not freeze, ie frost does not occur.

Since the air with a higher temperature will contain a certain amount of water vapor, when it exchanges heat with the evaporator 4, the water vapor will condense into condensed water, and under the action of gravity, the condensed water will flow downward and leave the evaporator. Condensed water can thus be removed. However, in reality, due to water tension and other factors, the condensed water will increase, and frost will form before it completely leaves the evaporator; and as the frost becomes thicker, the air circulation in the refrigerator will be poor. smooth, leading to poor cooling effect, at this time it is necessary to defrost. It can be seen that in order to minimize the amount of frost that needs to be removed, it is necessary to remove the condensed water on the evaporator as much as possible and reduce the cost as much as possible.

Therefore, how to remove the condensed water on the evaporator and how to remove the condensed water as low as possible has become an urgent problem to be solved.

Detailed ways

The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

And, it should be understood that although the terms first, second, etc. may be used herein to describe various elements or structures, these described objects should not be limited by these terms. These terms are only used to distinguish these described objects from one another. For example, the first running state receiving module may be called the second running state receiving module, and similarly the second running state receiving module may also be called the first running state receiving module, which does not depart from the protection scope of the present application.

Embodiment 1 of the present invention provides a method for removing condensation water in an air-cooled refrigerator. As shown in FIG. 1 , the air-cooled refrigerator includes an evaporator 4 and a storage compartment 2 for storing storage items , the blower fan 1 that is arranged in the air path from the evaporator 4 to the storage compartment 2 and a state sensor for detecting the operating state of the air-cooled refrigerator, as shown in Figure 3, the decondensation The water method consists of the following steps:

Step 301: receiving the operating state of the air-cooled refrigerator detected by the state sensor;

Step 302: When it is determined that the operating state satisfies the preset condition, stop the operation of the evaporator 4, and adjust the steering of the fan 1 to the first steering, and the first steering makes the air flow in the air path from Flow over the surface of the evaporator 4 from top to bottom or from the side.

Here, in the air-cooled refrigerator, the state sensor can be a virtual module or a hardware device. The state sensor can be a program module in the control system of the air-cooled refrigerator, and the start-up time of the refrigerator, the time when various events (such as opening and closing the door, controlling the direction of fan 1, etc.) of the refrigerator can be obtained by using this program module; It can also be a hardware device, for example, a temperature sensor, a humidity sensor, etc. that are arranged inside the storage compartment 2; a temperature sensor that is used to detect the temperature of the surrounding environment, a humidity sensor that detects the humidity of the surrounding environment, etc., that are arranged outside the refrigerator body; And the state sensor can also include the above-mentioned virtual module and hardware device at the same time. Similar to this, the running status includes: the temperature and humidity of the storage compartment 2, the start-up time of the refrigerator, the temperature and humidity of the surrounding environment, and the like.

As shown in Figure 1, in the design of a common refrigerator, the air outlet 5 is usually above the evaporator 4, and the return air outlet 3 is usually located below the evaporator 4. Under the action of the fan 1, the airflow flows through the evaporator from bottom to top. 4, so that the airflow shown in Figure 1 is formed in the storage compartment 2; in step 302, the steering of the fan 1 is adjusted to the first steering, that is, the airflow flows through the evaporator 4 from top to bottom, As a result, the airflow shown in Figure 2 is formed in the storage compartment 2. At this time, under the action of the airflow, the condensed water on the surface of the evaporator 4 will flow down more easily, and then leave the evaporator 4. In the technical solution provided by the embodiment, no additional equipment is added, which reduces the cost.

It can be foreseen that if the air outlet 5 is located at the side of the evaporator 4, and the return air outlet 3 is located below the evaporator, and under the action of the fan 1, the airflow flows from the first side of the evaporator 4 to the second side, then in In step 302, in order to avoid sucking condensed water into the storage compartment 2, it is necessary to adjust the direction of the fan 1 so that the airflow flows from the second side to the first side of the evaporator 4. It can be seen that under the action of the airflow, The condensed water on the surface of the evaporator will flow to the side more easily, and then leave the evaporator, and in the technical solution provided by this embodiment, no additional equipment is added, which reduces the cost.

In step 302, it is necessary to judge whether to remove the condensed water according to the operating state, for example: to judge whether the condensed water has frozen according to the uninterrupted cooling time of the evaporator, and to remove the condensed water before freezing; The amount of condensed water is calculated based on the humidity of the room and the uninterrupted cooling time. When the condensed water accumulates to a certain amount, the condensed water needs to be removed. Preset conditions can be set more flexibly and intelligently according to the actual situation.

Preferably, the adjusting the turning direction of the fan to the first turning direction includes: adjusting the turning direction of the fan to the first turning direction and increasing the rotation speed. When the speed of the fan is increased, the flow rate of the airflow can be accelerated, so that the condensed water accumulated on the surface of the evaporator can be better removed. At this time, after adjusting the steering of the fan and increasing the speed, the fan needs to continue to rotate for a period of time (such as 3min, 5min, 10min, etc.); The flow direction of the airflow meets the requirements of the air-cooled refrigerator during normal cooling, and the speed also meets the requirements of normal cooling.

Preferably, the adjusting the steering of the fan to the first steering includes: adjusting the steering of the fan to the first steering, continuing to rotate for a preset first time, and then starting the evaporator to cool and adjusting the steering of the fan It is the second turning, and the second turning makes the flow direction of the airflow in the air path conform to the flow direction of the airflow of the evaporator during cooling. During the process of removing condensed water, the evaporator will be stopped and the steering of the fan will be adjusted. Therefore, when the work of removing condensed water is completed, it is necessary to start the evaporator and adjust the steering of the fan to a normal state. As an optional technical solution, the first time may be 3 minutes, 5 minutes or 10 minutes.

Preferably, receiving the operating state of the air-cooled refrigerator detected by the state sensor includes: receiving the latest time to adjust the turning direction of the fan to the second turning direction detected by the state sensor; Determining that the operating state satisfies a preset condition includes: when it is determined that the time interval between the current time and the time when the most recent adjustment of the wind turbine's steering to the second steering is greater than or equal to a preset second time threshold, then Meet the preset conditions. Here, every once in a while (greater than the second time threshold), the work of removing condensed water will be forced, regardless of the amount of condensed water accumulated on the surface of the evaporator, so this can better remove the condensed water on the surface of the evaporator , once the time interval is set properly, it can also ensure that no condensate accumulates on the surface of the evaporator. The second time threshold may be 30min, 1h, 2h and so on.

Preferably, the receiving the operating state of the air-cooled refrigerator detected by the state sensor includes: receiving the ambient temperature of the air-cooled refrigerator detected by the state sensor, the storage compartment temperature, the latest time to adjust the turning of the fan to the second turning, and the cumulative door opening time during this period; the determination that the operating state meets the preset conditions includes: according to the ambient temperature, storage The temperature of the object room and the cumulative time of opening the door set a third time threshold. When it is determined that the time interval between the current time and the time when the fan is adjusted to the second steering most recently is greater than or equal to the third time threshold, then the preset condition is met. Or the accumulated time of door opening (that is, the sum of the time the refrigerator door is in the open state for a period of time). During use, the temperature of the surrounding environment and the temperature of the storage room will affect the speed of condensed water accumulation on the surface of the evaporator. Moreover, opening the door will affect the temperature of the storage compartment. Therefore, it is necessary to flexibly set the third time threshold according to these factors, so that condensed water can be removed in a more suitable and more flexible and intelligent manner.

For example: when "the ambient temperature - the temperature of the storage room ≥ 50 ℃ and the accumulated door opening time ≥ 120s", the third time threshold = 30 minutes; when "50 ℃ > the ambient temperature - the temperature of the storage room ≥ 40 ℃ and the cumulative door opening time ≥ 120s", the third time threshold = 60min; when "40℃>surrounding temperature - storage compartment temperature ≥ 30℃ and the cumulative door opening time ≥ 120s", the third time threshold = 150min .

Step 402, when it is determined that the cooling mode is the continuous cooling mode and the evaporator is in a stop working state, start the fan to rotate and turn it to a first turning direction, the first turning direction makes the air flow in the air path flow from above to down or sideways over the surface of the evaporator.

In step 401, the air-cooled refrigerator has two kinds of refrigeration modes: the low-temperature stage and the continuous refrigeration stage; when the air-cooled refrigerator starts to work, the storage compartment 2 is reduced from a higher temperature (such as room temperature) to a lower temperature When the temperature is set, the cooling mode at this time is the cooling down stage; when the temperature of the storage compartment 2 is relatively close to the set temperature (for example, a difference of plus or minus 3 degrees), the cooling mode at this time is the continuous cooling stage.

In step 402, when the temperature of the storage compartment 2 is within the preset range of the set temperature (usually within plus or minus 2 degrees of the set temperature), the evaporator will stop cooling, and at this time, the storage compartment 2 The temperature of the air-cooled refrigerator will slowly rise, and when the temperature of the storage compartment 2 is not in the preset range of the set temperature, the control system of the air-cooled refrigerator will start the evaporator for cooling. When the evaporator stops cooling, some condensed water will accumulate on its surface, and the condensed water needs to be removed. Therefore, whenever the evaporator stops cooling, the condensed water can be removed to remove the condensed water on the surface of the evaporator more thoroughly.

Preferably, the starting the fan to rotate and turn to the first turn includes: starting the fan to rotate and turn to the first turn, and continue to turn for a preset fourth time.

The fourth time can be 3 minutes, 5 minutes, 10 minutes and so on.

Preferably, the preset fourth time of continuous rotation includes: during the fourth time of continuous rotation of the fan, the evaporator starts to refrigerate, then adjust the turning direction of the fan to the second turning direction, and the second turning direction makes the air path The flow direction of the airflow in the medium conforms to the flow direction of the airflow of the evaporator during refrigeration. If the evaporator starts cooling during the process of removing condensed water, in order to allow the air-cooled refrigerator to cool normally, it is necessary to adjust the fan to the direction of the air flow of the evaporator during cooling.
