Description

Technical Field

[0001] The invention relates to the technical field of refrigeration, in particular to a control method for preventing condensation of a refrigerator and a refrigerator. Background Art

[0002] At present, the refrigerator compartment has two doors, and the door opening method is biparting. Generally, a vertical beam is arranged in the middle of the left and right doors. The function of the vertical beam is to isolate the interior of the compartment from the external environment. However, due to the poor insulation of the vertical beam, condensation will occur on the surface of the vertical beam in a high humidity environment. Generally, a heating wire is arranged on the surface of the vertical beam. The heating wire is used to heat and increase the temperature of the vertical beam surface. When the temperature of the vertical beam surface is higher than the dew point temperature of the air, condensation will not occur on the surface of the vertical beam.

[0003] The existing scheme for controlling the vertical beam heating wire gives the vertical beam heating wire an opening time under a certain ambient temperature to heat the heating wire, and then the temperature of the vertical beam surface is always greater than the dew point temperature corresponding to different humidity in the environment, that is, no matter how the ambient humidity changes, the vertical beam always works at a high opening rate to ensure that the vertical beam surface temperature is higher than the dew point temperature under any humidity conditions. This leads to an increase in the energy consumption of the refrigerator, and the high temperature of the vertical beam also affects the temperature in the refrigerator to a certain extent, affecting the refrigeration and preservation effect of the refrigerator, and has the disadvantages of high energy consumption and poor refrigeration and preservation. Therefore, it is necessary to study a control method for anti-condensation of a refrigerator and a refrigerator to solve the above problems. Summary of the invention

[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0035] The terms "including" and "having" and any variations thereof in the present invention are intended to cover non-exclusive inclusions. Reference to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] Combination Figure 1 As shown, the present invention mainly relates to: a control method for preventing condensation of a refrigerator, which comprises:

[0037] Set at the preset ambient temperature T 环境 When the refrigerator is in operation, the initial opening rate of the heater of the beam structure between two adjacent doors of the refrigerator is 0, where the opening rate is defined as the heating time of the heater per unit time;

[0038] Get the surface temperature T of the beam structure when the opening rate is 0 表面 , and calculate T 表面 With T 露点n The difference T 表面 -T 露点n , where T 露点n Defined as the same ambient temperature T 环境 The following are the dew point temperature values ​​corresponding to the ambient humidity RH of n gears, n is 1, 2..., the larger the gear of ambient humidity, the greater the ambient humidity;

[0039] When you get T 表面 -T 露点n After that, judge T 表面 -T 露点n Whether T is satisfied 表面 -T 露点n ≥0;

[0040] When T 表面 -T 露点n ≥0, get T 表面 -T 露点n The minimum value of the difference T min , set T min The corresponding ambient humidity level is T 环境 The base point K of the heater opening rate 基点 ;

[0041] After obtaining K 基点 Then, set it at T 环境 The ambient humidity level is less than or equal to K. 基点 When the heater opening rate is equal to 0, the ambient humidity level is greater than K 基点 When the heater opening rate is greater than 0, the ambient temperature T 环境 At the same time, the higher the ambient humidity, the higher the dew point temperature of the beam structure.

[0042] In this embodiment, specifically, referring to the following table, under certain temperature and humidity conditions, taking an ambient temperature of 32° C. and a humidity of 75% as an example, the dew point temperature is 27.01° C. The data in the table can be obtained through temperature and humidity experiments.

[0043]

[0044] At 32℃ and humidity 75%, the surface temperature of the beam structure must be higher than 27.01℃ to ensure that there is no condensation on the surface of the beam structure. According to the test data, the opening rate of the heater installed on the beam structure must reach 18 seconds within 1 minute to ensure that the surface temperature of the beam structure is higher than the dew point temperature to prevent condensation on the surface of the beam structure.

[0045] The value of the opening rate is, for example, 20s / min.

[0046] The ambient humidity level is less than or equal to K 基点 Equivalent to ambient humidity less than or equal to T min The corresponding ambient humidity. The ambient humidity level is greater than K 基点 Equivalent to ambient humidity greater than T min The corresponding ambient humidity.

[0047] Taking 32°C as an example, when the heater opening rate of the beam structure is 0, the surface temperature of the beam structure is 12.7°C. According to the table, the humidity is 35% when it is greater than and closest to 12.7°C. That is to say, at 32°C, when the humidity is less than or equal to 35%, the heater does not need to heat.

[0048] Get the surface temperature T of the beam structure when the opening rate is 0 表面 , then find a value greater than T 表面 and is closest to T 表面 By knowing the condensation temperature, the temperature and humidity conditions under which the heater does not need to be heated can be obtained. Therefore, according to the relationship between condensation and temperature and humidity, the triggering conditions for starting the heater can be found to control the opening and closing of the heater. It is easy to control the opening and closing of the heater, easy to control, and easy to implement. In this way, the heater is not started under any temperature and humidity conditions, which saves energy and avoids the temperature inside the refrigerator from rising. It has the advantages of energy saving, high efficiency, and good refrigeration and preservation effects.

[0049] Among them, when the heater opening rate of the beam structure is 0, no value greater than T 表面 and is closest to T 表面 The condensation temperature is directly increased by the following method to increase the heater opening rate to obtain T 环境 The method of the heater opening rate for the ambient humidity RH at n levels.

[0050] Combination Figure 2 As shown, in this embodiment, the control method for preventing condensation of the refrigerator further includes:

[0051] Get in T 环境 When the ambient humidity is greater than K 基点 The methods of opening rate include:

[0052] Get the heater's opening rate. Increase the heating time by 1 unit. 单位1 The surface temperature of the beam structure is T 表面1 , and calculate T 表面1 With T 露点N The difference T 表面1 -T 露点N , N is K 基点 A value between and n;

[0053] When you get T 表面1 -T 露点N After that, judge T 表面1 -T 露点N Whether T is satisfied 表面1 -T 露点N ≥0;

[0054] When T 表面1 -T 露点N ≥0, get T 表面1-T 露点N The minimum value of the difference T min1 , set at T 环境 Next, T min With T min The heater opening rate corresponding to the ambient humidity between 1 is t 单位1 .

[0055] Preferably, the aforementioned 1 unit heating time t 单位1 It is defined as the heater working for 1 second within 1 minute.

[0056] Specifically, T 露点N The ambient humidity level is greater than K 基点 gear.

[0057] After obtaining K 基点 After that, set the heater opening rate to increase by 1 unit heating time t 单位1 , then find a value greater than T 表面 and is closest to T 表面 The condensation temperature can be used to obtain the heating time t of the heater working for 1 unit 单位1 The temperature and humidity conditions for the beam structure to have no condensation on the surface are based on the fact that when the ambient temperature is the same, the lower the humidity, the lower the condensation temperature. 环境 Next, T min With T min The heater opening rate corresponding to the ambient humidity between 1 is t 单位1 . It has the advantages of simple testing method, reduced workload and improved efficiency.

[0058] Furthermore, when T 表面1 -T 露点N When <0, the heater opening rate is set to increase by Δ n Unit heating time t 单位Δ Until the surface temperature of the beam structure T 表面Δ With T 露点N The difference T 表面Δ -T 露点N ≥0, where Δ n >t 单位1 , is 2, 3…;

[0059] When T 表面Δ -T 露点N ≥0, get T 表面Δ -T 露点N The minimum value of the difference T minΔ , set at T 环境 Next, T min With T minΔ The heater opening rate corresponding to the ambient humidity is t 单位Δ .

[0060] Specifically, taking 32°C as an example, when the heater opening rate of the beam structure is 1 minute and the heater works for 1 second, the surface temperature of the beam structure is 15°C. At this time, the dew point temperatures greater than 35% in the table are all greater than 15°C. Therefore, the heater opening rate of the beam structure needs to be increased successively until T 表面Δ -T 露点N ≥0, for example, when the heater opening rate of the beam structure increases to 5 seconds within 1 minute, the surface temperature of the beam structure is 19°C. According to the table, 45% is greater than and closest to 19°C, that is, the heater works for 5 seconds when the humidity is 35% to 45%. The method of the present invention not only reduces the workload, but also takes into account the advantages of energy saving and high efficiency. The working time of the heater of the beam structure is set in sections and intervals.

[0061] Furthermore, the anti-condensation control method of the refrigerator also includes:

[0062] After obtaining t 单位1 and / or 单位Δ When K is obtained, repeat 基点 Subsequent operations until T is obtained 环境 The heater opening rate of the ambient humidity RH of n gears. To complete T 环境 The numerical values ​​of the activation rate of the usage scenarios under all humidity conditions make the control method more comprehensive and complete.

[0063] Furthermore, the anti-condensation control method of the refrigerator also includes:

[0064] After obtaining T 环境 After the opening rate of the heater of the n-level ambient humidity RH is obtained, the maximum range of the ambient temperature change of the refrigerator is obtained, and the maximum range of the ambient temperature change of the refrigerator is divided into m levels according to the preset temperature difference between two adjacent temperature levels. 环境 The method of the heater opening rate at the time is to obtain the heater opening rates of m gears in sequence;

[0065] Among them, T 环境 is a preset ambient temperature value in the m gears. Thus, the opening rate values ​​in the use scenarios of n*m temperature and humidity environments are obtained. This makes the control method more comprehensive and complete.

[0066] The maximum range of the ambient temperature change of the refrigerator can be set according to the ambient temperature of the refrigerator plus a certain threshold.

[0067] In order to control more precisely, the temperature difference between two adjacent temperature levels is set to 5°C. For example, the maximum range of the ambient temperature of the refrigerator is -10°C to 45°C.

[0068] Furthermore, the same ambient temperature T 环境 The method for obtaining n gears includes:

[0069] The maximum range of the ambient humidity change of the refrigerator is obtained, and the maximum range of the ambient humidity change is divided into n levels according to the preset humidity difference between two adjacent humidity levels. For example, the maximum range of the ambient humidity change of the refrigerator is 5% to 95%.

[0070] In order to control more precisely, the humidity difference between two adjacent humidity gears is set to 5%. The humidity difference between two adjacent gears in the n gears can be set to be the same.

[0071] The maximum range of the refrigerator's ambient humidity change can be set based on the refrigerator's operating environment humidity plus a certain threshold.

[0072] Furthermore, when the humidity is the same, the higher the ambient temperature, the higher the condensation temperature. When the ambient temperature is the same, the greater the humidity, the higher the condensation temperature.

[0073] In order to solve the above problems, the present invention also provides a refrigerator.

[0074] A refrigerator includes a control unit, the control unit includes a memory and a processor, the memory stores a computer program that can be run on the processor, and when the processor executes the computer program, the anti-condensation control method of the refrigerator as described above is implemented.

[0075] Combination Figure 3 As shown, the refrigerator further includes an infrared sensor 1 disposed near the outside of the beam structure, wherein the infrared sensor 1 is used to detect the surface temperature of the beam structure. The infrared sensor 1 detects the surface temperature of the beam structure in real time, and the opening rate of the heater under different dew point temperatures is automatically and quickly determined by program control through the surface temperature of the beam structure and the dew point temperature of the corresponding ambient temperature and humidity. At the same time, the infrared sensor 1 may not be disposed on the beam structure, which is convenient for simple setting.

[0076] Further, the refrigerator further comprises a refrigerating compartment 21. The two adjacent doors are a left door 22 and a right door 23 which are opened to the left and right of the refrigerating compartment 21. The beam structure is a vertical beam 3 between the left door 22 and the right door 23. It is understandable that the beam structure is also arranged between the upper and lower doors.

[0077] The heater is a heating wire 4 arranged on the vertical beam 3. Preferably, the vertical beam 3 includes a vertical beam assembly 31 and a vertical beam sheet metal shell 32 arranged on the front side of the vertical beam assembly 31. The vertical beam assembly 31 and the vertical beam sheet metal shell 32 define an installation space for installing the heating wire 4. This has the advantage of being easy to install.

[0078] The present invention can be applied to many occasions and devices where heating wires 4 are used to eliminate condensation, such as arranging heating wires 4 inside transparent doors of freezers or refrigerators.

[0079] Compared with the prior art, the anti-condensation control method of the refrigerator provided by the present invention and the refrigerator are provided by obtaining the surface temperature T of the beam structure when the opening rate is 0. 表面 Then, by setting the ambient humidity RH in n gears, we can obtain a value greater than T 表面 and is closest to T 表面 The condensation temperature is used to determine the K when the opening rate is 0. 基点 , the temperature and humidity conditions under which the heater does not need to be heated and condensation can be obtained. Based on the relationship that the higher the ambient humidity, the higher the dew point temperature of the beam structure, the trigger condition for starting the heater is found to control the opening and closing of the heater. It is easy to control the opening and closing of the heater, easy to control, and easy to implement. Thereby avoiding starting the heater under any temperature and humidity conditions, saving energy, and avoiding the temperature inside the refrigerator from rising. It has the advantages of energy saving and high efficiency, good refrigeration and preservation effect, good anti-condensation effect, and neat and clean inside the refrigerator.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
