Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-condensation, in particular to an anti-condensation refrigerator. Background Art
[0002] Anti-condensation is one of the most critical technologies in the use of refrigerators. The level of anti-condensation in refrigerators will directly affect the user experience. At present, most refrigerators on the market use the following two anti-condensation technologies: (1) arranging electric heating wires at condensation-prone places such as the middle beam to increase the temperature at the false beam to prevent condensation; (2) arranging de-condensation pipes to increase the temperature of the corresponding positions (generally arranging de-condensation pipes around the inner tank) to prevent condensation. However, these two methods have certain defects. The de-condensation pipe is generally arranged after the condenser. The temperature of the high-temperature and high-pressure gas output by the compressor is greatly reduced after passing through the condenser and then flows into the de-condensation pipe. At this time, the temperature will not be too high. However, when the ambient temperature and humidity of the refrigerator are high, the temperature of the de-condensation pipe may be close to the dew point temperature. When the refrigerator is in high temperature and high humidity, the anti-condensation effect cannot be achieved. If the high-temperature and high-pressure gas output by the compressor goes through the de-condensation pipe first and then goes through the condenser, the temperature of the de-condensation pipe is too high, which increases the heat load of the refrigerator and the corresponding energy consumption will increase accordingly. Utility Model Content

[0019] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.
[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0021] See also Figure 1 and Figure 2 , Figure 1 This is a front view of a partial structure of an anti-condensation refrigerator according to an embodiment of the utility model. Figure 2 The utility model provides an anti-condensation refrigerator, wherein a press chamber 1 is arranged at the bottom of the box body of the anti-condensation refrigerator, and a condenser 2, a compressor, a cooling fan 3 and a damper 4 are arranged in the press chamber 1. Figure 2 The condenser 2 and the cooling fan 3 are both arranged between the top surface 5 and the bottom surface 6 of the press chamber, and a sealing sponge 7 is also arranged in the press chamber 1. Moreover, the cooling fan 3 is arranged on the first side 21 of the condenser 2, the damper 4 is arranged on the second side 22 of the condenser 2, and the opening 41 of the damper 4 corresponds to the middle part facing the condenser 2, and the damper 4 can be opened or closed.
[0022] In addition, the anti-condensation refrigerator further comprises a dew removal pipe, and the dew removal pipe is connected to the outlet end of the condenser.
[0023] Of course, the anti-condensation refrigerator of the utility model also includes an evaporator. When the anti-condensation refrigerator is working normally, the compressor compresses the refrigerant (coolant) into a high-temperature and high-pressure gas, and the compressor delivers the high-temperature and high-pressure refrigerant to the condenser 2 to condense it into a medium-temperature and high-pressure liquid. Then the medium-temperature and high-pressure liquid refrigerant passes through the dew removal pipe and enters the evaporator to absorb heat and evaporate into a low-temperature and low-pressure gas, and finally returns to the compressor again to complete a refrigeration cycle. When the high-temperature and high-pressure refrigerant vapor discharged by the compressor enters the condenser 2 for condensation, the cooling fan 3 will blow air to the condenser 2 to fully dissipate heat. Under the forced convection of the cooling fan 3, the external cold air flows through the condenser 2 to be heated and the temperature is increased. Generally speaking, the speed of the cooling fan 3 is either constant or adjusted according to the ambient temperature (the higher the ambient temperature, the greater the speed). In this way, although the heat dissipation effect of the condenser 2 is guaranteed, if the external ambient temperature remains unchanged, the speed of the cooling fan is constant, and the temperature of the refrigerant entering the dew-removing pipe will not change significantly. In this way, for environments with different ambient humidity, the dew-removing effect of the dew-removing pipe will be quite different, and it cannot be well guaranteed that there is no condensation on the outer surface of the refrigerator, resulting in a poor user experience. The utility model can solve the above problem. The utility model adjusts the ambient humidity by opening or closing the damper 4 set in the middle part of the condenser 2, which can quickly adjust the ambient temperature and humidity, and can play an anti-condensation effect.
[0024] Preferably, in order to facilitate cooling air to pass through the damper 4, the damper 4 is arranged parallel to the condenser 2. However, the present invention is not limited thereto, and in another embodiment, the damper 4 is arranged at a first angle to the condenser 2, and the first angle is less than 30 degrees.
[0025] In addition, preferably, the first side 21 of the condenser 2 is opposite to the second side 22 of the condenser 2 .
[0026] In actual use, in one embodiment, the damper 4 can be installed on the condenser 2. In another embodiment, a mounting frame can also be provided in the press room 1 to fix and install the damper 4.
[0027] The condenser 2 includes a condenser tube 23 and a heat sink 24. There are microchannels between the heat sink 24. The damper is installed in the middle of the condenser 2, and the opening and closing of the damper 4 can be controlled according to the ambient humidity, thereby ensuring that the temperature at the refrigerator beam position rises and is always above the dew point temperature, thereby achieving the effect of preventing condensation.
[0028] In addition, the anti-condensation refrigerator also includes a switch module, a sensing module and a control module. The switch module controls the connection of the damper 4, the control module connects the sensing module and the switch module, the sensing module senses the ambient humidity in the press chamber 1, and the control module controls the switch module to open or close the damper 4 according to the ambient humidity.
[0029] Specifically, for example, a preset environmental humidity value can be pre-set. When the actual environment detected by the sensing module is less than or equal to the preset environmental humidity, the control module controls the switch module to close the damper 4. At this time, all the cooling air is cooled by the condenser. When the actual environment detected by the sensing module is greater than the preset environmental humidity, the control module controls the switch module to open the damper 4. At this time, most of the cooling air is sucked away by the cooling fan 3 through the opening 41 of the damper 4, and only a small part of the cooling air participates in the cooling of the condenser 2. At this time, the temperature of the condenser 2 will be much higher than before, ensuring that the temperature at the refrigerator beam position rises, so that condensation will not be generated.
[0030] In actual use, the opening or closing of the damper 4 can be achieved through shutters. For example, the switch module includes: a driving mechanism, a rotating shaft and a shutter. The shutter is installed at the opening 41 of the damper 4. One end of the rotating shaft is connected to the driving mechanism, and the other end of the rotating shaft is connected to the shutter. The driving mechanism drives the rotating shaft to rotate upon receiving the command, thereby driving the shutter to rotate to realize the opening or closing of the damper 4. In this embodiment, the damper 4 can also be opened or closed in other ways, as long as the damper 4 can be opened or closed.
[0031] The condenser is, for example, a ring condenser.
[0032] In one embodiment, the sensing module is, for example, a humidity sensing module. In addition, the anti-condensation refrigerator further comprises a temperature sensing module, which is connected to the control module. For more precise control, the opening and closing of the damper can be controlled by sensing the ambient temperature and the ambient humidity at the same time.
[0033] In another embodiment, the sensing module is an ambient temperature and humidity sensor, which can sense ambient temperature and ambient humidity simultaneously.
[0034] In addition, the control module is also connected to the cooling fan control. On the basis of the above, the ambient temperature and ambient humidity can be further controlled by adjusting the speed of the cooling fan. For example, when the ambient humidity increases, the control module controls the speed of the cooling fan to decrease, thereby increasing the ambient temperature; when the ambient humidity decreases, the control module controls the speed of the cooling fan to increase, thereby reducing the ambient temperature. Specifically, for example, a storage module can also be set, and a relationship comparison table between the ambient temperature, ambient humidity and the speed of the cooling fan can be set and stored in the storage module. The control module obtains the cooling fan speed control value according to the relationship comparison table based on the ambient temperature and ambient humidity, and adjusts the voltage supplied to the cooling fan through the relay, thereby changing the speed of the cooling fan.
[0035] It is optional, because in practice, if the ambient humidity is controlled as soon as the compressor of the anti-condensation refrigerator is started to control the temperature of the dew-removing pipe, it may cause insufficient heat dissipation of the condenser, resulting in poor refrigeration effect of each storage room of the anti-condensation refrigerator, further affecting the user experience. Therefore, the premise of corresponding control of the ambient humidity is to ensure that the refrigeration effect of each storage room in the refrigerator has reached the required standard (stable operation). Therefore, the control module is specifically configured as follows: when the storage room in the anti-condensation refrigerator meets the stable operation conditions, the ambient temperature and humidity of the refrigerator are obtained through the sensing module.
[0036] Moreover, further optionally, the refrigeration effect of each storage room in the anti-condensation refrigerator reaches the required standard generally means that the temperature in the storage room has been low to a certain extent and the refrigeration effect can be achieved without further lowering.
[0037] In addition, in actual applications, there may be measurement errors in the detection effect of the sensing module. In order to ensure the stability and accuracy of the detection results, it is better to perform multiple measurements to accurately determine the current environmental state. Therefore, the control module is specifically configured to: control the sensing module to continuously detect the ambient temperature and ambient humidity for multiple times, and obtain the average value of multiple detections.
[0038] In summary, the utility model controls the heat dissipation effect of the condenser by the switch state of the damper on the annular condenser, thereby controlling the condenser temperature. When the ambient humidity is high, the damper in the middle of the annular condenser opens, and at this time, most of the air suction of the fan flows in from the damper in the middle part (center position), thereby greatly reducing the heat dissipation effect of the condenser, making the condenser temperature very high, thereby causing the temperature at the refrigerator beam position to rise, always above the dew point temperature, so that condensation will not occur. Moreover, the utility model is easy to operate by setting a damper in the middle part of the condenser and solving the condensation problem by controlling the opening or closing of the damper, and does not need to use electric auxiliary heating to solve the condensation problem, thereby achieving energy saving and environmental protection; in addition, the utility model has a simple structural design and high process reliability.

It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
