Description

Technical Field

[0001] This application belongs to the field of refrigeration technology, and in particular relates to a refrigeration enclosure. Background Technology

[0002] Existing horizontal direct-cooling freezers have simple storage spaces, mostly consisting of a single compartment, and generally have freezing or refrigeration functions. During the refrigeration process, due to the long evaporator pipes and the different phases of the refrigerant within the evaporator, there are temperature differences between the upper, middle, and lower evaporators. These differences result in varying temperatures transferred to the inner liner, leading to poor temperature uniformity within the freezer. Furthermore, the settling effect of cold air causes the lower layer of the freezer to be significantly cooler than the upper layer, making accurate temperature detection difficult and resulting in inconsistencies between the set temperature and the actual temperature throughout the freezer.

Detailed Implementation

[0038] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0039] The following description refers to elements or components that are “connected” or “coupled” together. As used herein, “connected” may refer to one element / component being mechanically joined to (or directly connected to) another element / component, and is not necessarily direct. Similarly, “coupled” may refer to one element / component being directly or indirectly joined to (or directly or indirectly connected to) another element / component, and is not necessarily mechanical. However, it should be understood that although two elements are described as “connected” below in one embodiment, similar elements may be “coupled” in alternative embodiments, and vice versa. Therefore, although the schematic diagrams shown herein depict exemplary arrangements of elements, additional intermediate elements, devices, components, or members may still be present in an actual embodiment.

[0040] Horizontal freezers typically have large storage compartments, such as 100L, 150L, ​​or 200L. During the refrigeration process, due to the long circulation path of the refrigerant, the refrigerant's phase or temperature varies along the path, resulting in temperature differences at different points in the circulation path. This leads to varying temperatures reaching the inner liner, resulting in poor temperature uniformity within the freezer. Furthermore, due to the settling effect of cold air, the lower compartment is significantly cooler than the upper compartment, further complicating the temperature distribution within the freezer.

[0041] In related technologies, a temperature sensor is typically installed at the bottom of the compartment, and the readings from this sensor are used for correction. However, this method cannot accurately reflect the temperature at all locations. For example, if the refrigerator is set to 4°C, to ensure that the temperature throughout the refrigerator is ≤4°C, after correction, the upper part of the refrigerator will be warmer at 4°C, but the lower part will be <0°C. Food that should be refrigerated will be frozen, leading to user complaints.

[0042] This application provides a refrigeration chamber that arranges multiple temperature sensors along the air settling direction inside the chamber. The temperature sensors are staggered with the refrigeration piping. The temperature sensing conduit that houses the temperature sensors is composed of two parts: an inner liner and a shell. This design facilitates installation and allows for the detection of the temperature inside the chamber under different settling programs, thereby improving the accuracy of temperature monitoring inside the chamber.

[0043] Reference Figure 1 , Figure 1A first structure of a refrigeration chamber is shown. One embodiment of this application proposes a refrigeration chamber. In this embodiment, the refrigeration chamber 10 includes a shell 11, an inner liner 12, a refrigeration unit 13, a plurality of first temperature-sensing conduits 14, a plurality of second temperature-sensing conduits 15, and a plurality of temperature-sensing probes 16. The inner liner 12 is disposed within the shell 11 and forms a compartment; the refrigeration unit 13 is disposed within the inner liner 12 to refrigerate the compartment; the first temperature-sensing conduits 14 are disposed within the inner liner 12, with a first portion 141 near the first end arranged along the air settling direction within the compartment; the second temperature-sensing conduits 15 pass through the shell 11, with one end of each second temperature-sensing conduit 15 detachably connected to the second end of each first temperature-sensing conduit 14; the temperature-sensing probes 16 are disposed within the first temperature-sensing conduits 14 and located at the first end to detect the temperature of the compartment.

[0044] It should be noted that the refrigeration unit can be a horizontal freezer, such as a horizontal direct-cooling freezer or a horizontal air-cooling freezer. Figure 1 The structure of a horizontal direct-cooling freezer is shown, and this embodiment is described using a horizontal direct-cooling freezer as an example.

[0045] It is understood that the refrigeration unit 10 is also equipped with a refrigeration system, which typically includes a compressor, an evaporator, and a condenser. In this embodiment, the refrigeration unit 13 includes an evaporation pipe 131, which corresponds to the evaporator in the refrigeration system.

[0046] The evaporator pipe 131 is spirally mounted on the inner liner 12. Figure 1 Taking the X direction as the horizontal direction and the Y direction as the vertical direction as an example, the evaporator pipe 131 is arranged in a spiral pattern along the vertical direction, that is, the main body of the evaporator pipe 131 is arranged in a horizontal direction, and two adjacent main bodies can be connected by a U-shaped section.

[0047] In this embodiment, the first part 14 of the first temperature-sensing conduit 14 is misaligned with the evaporation conduit 131.

[0048] The first part 141 of the first temperature-sensing conduit 14 near its first end is not in contact with the main body of the evaporation pipe 131, forming a staggered arrangement. For example, the first part 141 of the first temperature-sensing conduit 14 near its first end is arranged between the main bodies of two adjacent evaporation pipes 131 and is parallel to each other. Since the evaporator temperature usually changes rapidly and is 3-5°C lower than the internal temperature, the staggered arrangement ensures that the first temperature-sensing conduit 14 does not contact the evaporation pipe, avoiding frequent start-stop of the compressor that could cause the internal temperature to be too high.

[0049] The air settles vertically, and the first part 141 of each first temperature-sensing conduit 14 is arranged vertically, meaning that the first part 141 of each first temperature-sensing conduit 14 is at a different height from the bottom of the compartment. The temperature-sensing probe 16 is located at the first end of the first temperature-sensing conduit 14 to detect the temperature at the location of the corresponding first part 141 of the first temperature-sensing conduit 14 within the compartment.

[0050] As an example, the first end of the first temperature-sensing conduit 14 can be positioned at the middle of the horizontal direction of the compartment at the height of the corresponding first part 141, thereby more accurately detecting the temperature at that height within the compartment.

[0051] Multiple temperature sensors 16 are arranged vertically to detect the temperature at various heights within the room, thus providing a more accurate assessment of the room's temperature and facilitating more precise temperature control.

[0052] In some embodiments, the top of the inner liner 12 is provided with an opening, the inlet of the evaporation pipe 131 is arranged near the top of the inner liner 12, and the outlet of the evaporation pipe 131 is arranged near the bottom of the inner liner 12.

[0053] Continue to refer to Figure 1 The inner liner 12 has an opening at the top. The inlet of the evaporator pipe 131 is located in the upper pipe body, and the outlet of the evaporator pipe 131 is located in the lower pipe body. The refrigerant enters from the upper evaporator pipe 131, flows downwards, and then flows out from the bottom evaporator pipe 131. Because the refrigerant flows in from the top, there is more cooling in the upper part of the room, and less cooling in the lower part. Due to the settling of cold air, the cooling is transferred downwards, making the temperature inside the room more uniform.

[0054] In this embodiment, the temperature-sensing conduit is divided into a first temperature-sensing conduit 14 and a second temperature-sensing conduit 15; wherein, the first temperature-sensing conduit 14 is located inside the inner liner, and the second temperature-sensing conduit 15 is located on the outer shell. The second part 142 of the first temperature-sensing conduit 14 near the second end is used to connect to the second temperature-sensing conduit 15. During installation, the first temperature-sensing conduit 14 is first installed on the inner liner, and then the inner liner 12 is installed into the outer shell 11; then the second temperature-sensing conduit 15 on the outer shell 11 is connected to the first temperature-sensing conduit 14. This facilitates installation and avoids the problem of difficulty in passing the temperature-sensing conduit through the pre-drilled hole in the outer shell when the temperature-sensing conduit is directly installed in the inner liner.

[0055] Reference Figure 2 and Figure 3 , Figure 2 The first structure of the temperature-sensing conduit is shown. Figure 3 An enlarged view of the connection between the first temperature-sensing conduit 14 and the second temperature-sensing conduit 15 is shown. The temperature-sensing conduit as a whole can be straight, with one end of the second temperature-sensing conduit 15 connected to the second end of the first temperature-sensing conduit 14.

[0056] In some embodiments, the second end of the first temperature-sensing conduit 14 is provided with a connector 143 for inserting one end of the second temperature-sensing conduit 15 into the connector 143.

[0057] The connector 143 can be integrally formed with the first temperature-sensing conduit 14. The inner diameter of the connector 143 can be less than or equal to the outer diameter of the second temperature-sensing conduit 15, and the connector 143 and the second temperature-sensing conduit 15 are interference-fitted. The second temperature-sensing conduit 15 can be directly inserted into the connector 143.

[0058] During installation, the first temperature-sensing conduit 14 is installed in the inner liner and then inserted into the shell 11. Then, the second temperature-sensing conduit 15 passes through the reserved hole on the shell 11 and is inserted into the connector 143, which is simple to match.

[0059] In some embodiments, a rubber plug 17 is provided on the outer surface of the portion of the second temperature-sensing conduit 15 that mates with the housing 11.

[0060] The plug 17 can be made of elastic materials such as rubber. The plug 17 is used to seal the gap between the second temperature sensing conduit 15 and the housing 11, thereby improving the airtightness of the housing.

[0061] Reference Figure 4 , Figure 4 An arrangement of a temperature-sensing conduit is shown. In some embodiments, the first portion 141 of the first temperature-sensing conduit 14 is attached to the inner liner 12, and the second portion 142 of the first temperature-sensing conduit 14 near the second end is arranged on the side of the evaporation pipe 131 away from the inner liner 12.

[0062] In this embodiment, the first portion 141 and the second portion 142 of the first temperature-sensing conduit 14 extend in different directions. For example... Figure 1 In the middle, the first part 141 extends horizontally, and the second part 142 is arranged vertically. The second part 142 is arranged on the side of the evaporator pipe 131 away from the inner liner 12, and its extension direction is more free, which facilitates the wiring arrangement of the temperature sensor 16.

[0063] Therefore, the connection between the first part 141 and the second part 142 extends from the side of the evaporation pipe 131 away from the inner liner 12 to the side closer to the inner liner 12, so as to realize the transition of the second part 142 to the first part 141, ensuring that the first part 141 fits the inner liner 12 and improving the detection accuracy.

[0064] Reference Figure 5 , Figure 5 A second structure of the temperature-sensing conduit is shown. In some embodiments, at least a portion of the first temperature-sensing conduit 14 has a bend 144, the first end of which is connected to the first portion 141 of the first temperature-sensing conduit 14.

[0065] A bend 144 is disposed between the first part 141 and the second part 142 of the first temperature-sensing conduit 14. The bend 144 enables the transition between the first part 141 and the second part 142.

[0066] In some embodiments, the number of first temperature-sensing conduits 14 is greater than or equal to three, and the first portion 141 of at least one first temperature-sensing conduit 14 is arranged near the bottom of the compartment, and the first portion 141 of at least one first temperature-sensing conduit 14 is arranged near the top of the compartment.

[0067] In this embodiment, by installing temperature sensors 16 near the bottom and top of the chamber, the evaporation inlet temperature and evaporation outlet temperature of the evaporation pipe 131 can be detected, thereby determining the highest or lowest temperature in the chamber and facilitating the detection of the temperature range in the chamber.

[0068] The first portion 141 of the first temperature-sensing conduit 14, excluding the bottom and top portions, is located near the middle of the chamber. For example, with a total of three first temperature-sensing conduits 14, one first portion 141 of the first temperature-sensing conduit 14 is arranged near the bottom of the chamber, one first portion 141 of the first temperature-sensing conduit 14 is arranged near the top of the chamber, and one first portion 141 of the first temperature-sensing conduit 14 is arranged near the middle of the chamber, thereby controlling the evaporation inlet temperature, evaporation middle temperature, and evaporation outlet temperature of the evaporation pipe 131. Of course, the total number of first temperature-sensing conduits 14 can be greater.

[0069] In some embodiments, the first temperature-sensing conduit 14 located at the bottom of the compartment is straight, and the first temperature-sensing conduit 14 other than the bottom has a bend 144, and the conduit portions connected to both ends of the bend 144 are straight.

[0070] In this embodiment, the second ends of the first temperature-sensing conduit 14 converge in the same area to facilitate the routing of the temperature-sensing probe 16 and its connection to the controller. Typically, the controller is located at the bottom of the refrigeration unit 10, so except for the first temperature-sensing conduit 14 at the bottom, the conduit is redirected via the bend 144, while the first temperature-sensing conduit 14 at the bottom extends directly in a straight line.

[0071] Reference Figure 6 , Figure 6 An installation process for a temperature sensor 16 is illustrated. It should be noted that the temperature sensor 16 can be inserted into the temperature sensing conduit after the first temperature sensing conduit 14 and the second temperature sensing conduit 15 have been installed. Therefore, the first temperature sensing conduit 14 is configured to allow the temperature sensor 16 to move between its first and second ends. The diameters of the first temperature sensing conduit 14 and the second temperature sensing conduit 15 should allow for the movement of the temperature sensor 16.

[0072] Reference Figure 7 , Figure 7The structure of a bending portion 144 is shown. The structural design of the bending portion 144 needs to ensure that the temperature sensing probe 16 can pass through.

[0073] The small diameter R1 of the through-hole arc track satisfies:

[0074] The large diameter R1 of the through-hole arc track satisfies: R2 ≥ R1 + c;

[0075] Where, a is the diameter of the temperature sensing probe 16, b is the length of the temperature sensing probe 16, and c is the diameter of the passage inside the bending portion 144.

[0076] In some embodiments, the refrigeration cabinet 10 further includes a main control board 17. The main control board 17 is arranged outside the cabinet shell 11 and is communicatively connected to the temperature sensing probe 16; among them, each second temperature sensing conduit 15 is arranged on one side of the cabinet shell 11 close to the main control board 17, and the second ends of each first temperature sensing conduit 14 are arranged on one side of the inner liner 12 close to the main control board 17.

[0077] In this embodiment, the temperature sensing probe 16 is connected to the main control board through a signal line. By arranging the temperature sensing conduits close to the main control board, it is convenient for the wiring of the temperature sensing probe 16. As Figure 8 shown, if the main control board 17 is arranged at the lower right corner of the refrigeration cabinet, then the second ends of the first temperature sensing conduits 14 are arranged towards the lower right corner of the inner liner 12, and the second temperature sensing conduits 15 are coaxially arranged with the second parts of the first temperature sensing conduits 14.

[0078] Refer to Figure 8 Figure 8 shown, the second structure of the refrigeration cabinet is shown. In some other embodiments, the refrigeration cabinet 10 can be a horizontal air-cooled freezer, and the refrigeration unit 13 can adopt an air-cooling unit (not shown in the figure). The air-cooling unit realizes refrigeration of the inner liner 12 by circulating cold air in the compartment. As an example, cold air can be blown in from the top of the compartment and blown out from the bottom of the compartment. In the horizontal air-cooled freezer, the first temperature sensing conduits 14, the second temperature sensing conduits 15 and the main control board 17 can also adopt the same arrangement, which will not be elaborated here.

[0079] In some embodiments, the main control board 17 can be electrically connected to the refrigeration system and can control the operation of the refrigeration system according to the measured temperatures fed back by each temperature sensing probe 16.

[0080] As an example, during the operation of the compressor, the main control board 17 can judge whether the condition (T1×n1 + T2×n2 + T3×n3) / 3 < T - △T is satisfied. If it is satisfied, the main control board 17 controls the compressor to stop running; if it is not satisfied, the main control board 17 controls the compressor to run. When the compressor is stopped, the main control board 17 can judge whether the condition (T1×n1 + T2×n2 + T3×n3) / 3 ≥ T - △T is satisfied. If it is satisfied, the main control board 17 controls the compressor to run; if it is not satisfied, the main control board 17 controls the compressor to remain stopped.

[0081] Where T1 represents the measured temperature of the first temperature sensor 16, n1 represents the weighted number corresponding to T1, T2 represents the measured temperature of the second temperature sensor 16, n2 represents the weighted number corresponding to T2, T3 represents the measured temperature of the first temperature sensor 16, and n3 represents the weighted number corresponding to T3.

[0082] As an example, under an ambient temperature of 32℃ without humidification, a 151L direct-cooling freezer, with three temperature sensors installed according to the design scheme, maintains the internal temperature within ±0.5℃ of the set temperature through adjustment, achieving extremely high accuracy. This significantly reduces power consumption and provides precise cooling based on user-demanded temperatures, preventing excessive cooling. Relevant implementation parameters can be found in Table 1 below:

[0083] Table 1. Actual center temperature inside the chamber under different set temperatures (unit: °C)

[0084]

[0085] It should be noted that in this example, after the refrigeration unit 10 is initially powered on, the internal heat exchange reaches equilibrium. The above-mentioned control method can be implemented after the heat exchange in the compartment has reached equilibrium. After the refrigeration unit 10 is initially powered on, the temperature T is set, and the temperature difference between the start-up and shutdown points ΔT is set. Since the internal temperature has not yet reached the set temperature, the temperature measured by the temperature sensor is close to the evaporator temperature and is too low. The precise temperature control program described above will only be implemented after the heat exchange between the evaporator, inner liner, and the internal space has stabilized. Typically, after the heat exchange in the compartment has stabilized, the compressor will periodically stop to control the temperature. Therefore, the main control board 17 can determine whether the compressor has stopped after the refrigeration unit 10 is powered on. If so, it indicates that the temperature in the compartment has reached equilibrium, and the precise temperature control program described above will be executed.
