Description

Technical Field

[0001] This utility model relates to the field of freezers, and more particularly to a refrigeration device and a freezer having a refrigeration device. Background Technology

[0002] Freezers (refrigerated display cases) are widely used devices for preserving food and other items at low temperatures. The basic function of a freezer is refrigeration, maintaining a suitable low temperature inside. A freezer's refrigeration system generally consists of four basic components: a compressor, a condenser, a capillary tube or thermostatic expansion valve, and an evaporator. Refrigerant (a liquid that boils at low pressure and low temperature, absorbing heat during boiling) circulates in the system. The compressor increases the gas pressure of the refrigerant, creating liquefaction conditions. As the refrigerant passes through the condenser, it condenses and releases heat. Then, as it passes through the capillary tube, its pressure and temperature decrease, and finally, as it passes through the evaporator, it boils and vaporizes, absorbing heat. Of course, freezers also exist that use other refrigeration methods (such as refrigeration diodes).

[0003] However, the existing problems include:

[0004] 1. In certain consumption scenarios (such as mini convenience stores), it is common to encounter situations where freezers are provided for cold drinks, but the refrigeration function of the freezer or refrigerator is lacking, which cannot meet the needs of refrigerating food (such as dairy products such as yogurt), resulting in a relatively limited function and application scenario for the freezer.

[0005] 2. In existing horizontal freezers, there is usually a significant waste of space in the area near the glass lid at the top (vertically within a depth range of 10-15cm) because the temperature is above -18℃.

[0006] Therefore, this utility model proposes a refrigeration device and a freezer with a refrigeration device to overcome the defects of the prior art. Utility Model Content

[0056] Implementation Method 1

[0057] like Figures 1 to 5As shown, this utility model provides a refrigeration device that uses cold air inside the freezer body 10 to create a refrigeration environment. The refrigeration device includes an outer shell 1 and at least one cooling channel 2. The outer shell 1 is installed on the top of the freezer body 10 and has a cavity inside, which is the refrigeration space 101 formed inside the outer shell 1. The cooling channel 2 has an air inlet and an air outlet. The air inlet of the cooling channel 2 is connected to the interior of the freezer body 10, and the air outlet of the cooling channel 2 is connected to the refrigeration space 101, so that the cold air inside the freezer body 10 enters the cooling channel 2 through the air inlet of the cooling channel 2, and then passes through the cooling channel 2 and the cooling channel 2 outlet in sequence to deliver the cold air to the refrigeration space 101, thereby creating a refrigeration environment in the refrigeration space 101.

[0058] The refrigeration device of this utility model is designed based on the existing freezer structure. An independent outer shell 1 is set on the top of the freezer body 10. The refrigeration space 101 of the refrigeration device of this application is formed inside the outer shell 1. The interior of the freezer body 10 and the refrigeration space 101 are connected by a cooling channel 2. That is, the cooling channel 2 is set inside the freezer body 10, and the air inlet of the cooling channel 2 is connected to the interior of the freezer body 10, and the air outlet of the cooling channel 2 is connected to the refrigeration space 101. Thus, the cold air inside the freezer body 10 is transported to the refrigeration space 101 through the cooling channel 2. The cold air inside the freezer body 10 forms a refrigeration environment in the outer shell 1 set separately on the top. Thus, foods that need low-temperature storage but do not need to be frozen (such as dairy products such as yogurt) can be stored in the refrigeration space 101. This utility model not only ensures that the freezing function of the freezer itself is not affected, but also realizes the refrigeration function by utilizing the cold air inside the freezer body 10. The freezing and refrigeration functions are integrated into one, making the functions and application scenarios of the freezer more diverse.

[0059] In one optional embodiment of this utility model, such as Figure 3 and Figure 5 As shown, the cooling channel 2 is formed on the inner wall of the freezer body 10, and the air inlet of the cooling channel 2 is located below the load surface 1001 inside the freezer body 10. Since the freezer's refrigeration system is mainly located in the inner wall of the freezer body 10, by directly forming the cooling channel 2 on the inner wall of the freezer body 10, the cold air output from the inner wall of the freezer body 10 can be directly obtained through the cooling channel 2 to cool the refrigerated space 101, resulting in better cooling effect. In this utility model, the load surface 1001 inside the freezer body 10 is a virtual plane preset inside the freezer body 10, such as... Figure 4As shown, the load surface 1001 is generally located in the middle or upper middle part of the freezer body 10. Since the freezer used in this utility model has a top opening structure, items are stored and retrieved through the top opening of the freezer. Therefore, the internal temperature of the freezer body 10 gradually increases from bottom to top. In the art, the position of the load surface 1001 is usually defined by the temperature inside the freezer body 10. That is, the temperature of the load surface 1001 inside the freezer body 10 is generally in the range of -18°C to -23°C. Below the load surface 1001, it can be ensured that the food that needs to be frozen (such as ice cream) is in a stable frozen state. In this invention, the air inlet of the cooling channel 2 is located below the load surface 1001 inside the freezer body 10. This avoids the use of cold air above the load surface 1001, which would cause further loss of cold air in the upper space of the freezer body 10 and lead to an increase in temperature. At the same time, it ensures that cold air with a lower temperature is obtained from inside the freezer body 10, and ensures that the cold air delivered to the refrigeration space 101 still maintains a low temperature (the cold air is always in a state of loss during the cold air transmission process), so as to achieve the purpose of creating a stable refrigeration environment.

[0060] It should be noted that, under actual working conditions, the position of the air inlet of the cooling channel 2 inside the freezer body 10 can be specifically set according to the temperature distribution inside the freezer body 10. It is preferable that the air inlet of the cooling channel 2 is as close as possible to the bottom inner wall of the freezer body 10. Since cold air sinks, the temperature inside the freezer body 10 is lower closer to its bottom inner wall. Setting the air inlet of the cooling channel 2 to the bottom inner wall or near the bottom inner wall of the freezer body 10 will result in the best cooling effect and will be least likely to affect the freezing function of the freezer body 10, thereby ensuring that both the refrigeration and freezing functions can be realized normally and stably.

[0061] Furthermore, such as Figure 3 and Figure 5As shown, the cooling channel 2 is vertically positioned at at least one apex on the inner wall of the freezer body 10. The specific structure of the cooling channel 2 is as follows: a first mounting plate 201 with a folded plate-like cross-section is provided inside the freezer body 10 near the apex. The first mounting plate 201 extends vertically along its length, and its two opposite edges are respectively sealed to the inner wall of the freezer body 10 near the apex. The first mounting plate 201 and two adjacent inner walls of the freezer body 10 form the four side walls of the cooling channel 2, thereby enclosing a rectangular cooling channel 2 through the first mounting plate 201 and the two adjacent inner walls of the freezer body 10 located at the apex. This arrangement allows the two adjacent inner walls of the freezer body 10 to simultaneously provide cold air to the cooling channel 2, resulting in a more sufficient supply of cold air and ensuring better cooling performance for the refrigerated space 101. In addition, the cooling aisle 2 should be placed as close as possible to the inner wall of the freezer body 10 to avoid occupying a large space inside the freezer body 10 and to ensure that it will not have a significant impact on the freezing space inside the freezer body 10.

[0062] Furthermore, such as Figure 5 As shown, vertically, the cooling channel 2 is positioned offset from the refrigeration components 1003 (such as compressors, cooling fans, etc.) of the freezer itself. Specifically, the cooling channel 2 and the refrigeration components 1003 can be respectively located on two opposite side walls of the freezer body 10, thereby maximizing the length of the cooling channel 2 so that it can extend to the bottom of the freezer body 10 and improve the delivery capacity of cold air.

[0063] In a preferred embodiment of this utility model, such as Figure 3 and Figure 5 As shown, the air inlet of the cooling channel 2 is located at the bottom of the refrigeration space 101. By setting the position of the air inlet of the cooling channel 2, the cold air near the bottom of the freezer body 10 can be fully utilized to achieve a better cooling effect on the refrigeration space 101. Moreover, utilizing the cold air near the bottom of the freezer body 10 will not affect the normal freezing function of the freezer body 10, ensuring that both the refrigeration and freezing functions can be realized normally and stably in this invention.

[0064] In one optional embodiment of this utility model, such as Figures 4 to 5 As shown, a first fan 3 is installed in the cooling channel 2. The first fan 3 provides driving force for the cold air inside the freezer body 10 to enter the refrigeration space 101. When it is necessary to supply cold air to the refrigeration space 101, the first fan 3 draws the cold air inside the freezer body 10 into the cooling channel 2, and then supplies it to the refrigeration space 101 through the cooling channel 2, thereby achieving an efficient and sufficient supply of cold air to the refrigeration space 101.

[0065] In this embodiment, the first fan 3 can be located in the middle of the cooling channel 2, near the air inlet of the cooling channel 2, or near the air outlet of the cooling channel 2. Preferably, the first fan 3 is located near the air outlet of the cooling channel 2, and the first fan 3 is positioned as high as possible to avoid occupying the freezing space inside the freezer body 10 and to minimize the impact of the first fan 3 on the normal use of the freezer.

[0066] Furthermore, such as Figure 3 and Figure 5 As shown, the air outlet of the cooling channel 2 is an open shape with a gradually increasing cross-sectional area from bottom to top. This design serves as a guide, allowing the cold air entering the refrigeration space 101 from the air outlet of the cooling channel 2 to quickly disperse within the refrigeration space 101. This results in better temperature uniformity within the refrigeration space 101 and avoids significant temperature differences between the air outlet positions near and away from the cooling channel 2, thus ensuring good overall refrigeration performance within the refrigeration space 101. Furthermore, the first fan 3 can be installed at this open position to meet the installation requirements of the first fan 3.

[0067] In one optional embodiment of this utility model, such as Figure 3 and Figure 5 As shown, a second fan 4 is installed inside the refrigerated space 101. The second fan 4 provides driving force for the cold air entering the refrigerated space 101 to flow away from the air inlet of the cooling channel 2. When supplying cold air into the refrigerated space 101, the second fan 4 can be kept on at all times, drawing the cold air entering the refrigerated space 101 from the air inlet of the cooling channel 2 away from the air inlet of the cooling channel 2. This allows the cold air to be quickly and evenly distributed within the refrigerated space 101, ensuring that the refrigeration temperature in different locations within the refrigerated space 101 is as consistent as possible, thus ensuring the overall refrigeration effect of the refrigerated space 101. When the temperature inside the refrigerated space 101 reaches the preset refrigeration temperature (e.g., 0 to 10°C), the first fan 3 and the second fan 4 can be stopped. The first fan 3 and the second fan 4 can be turned on again when the temperature inside the refrigerated space 101 exceeds the preset refrigeration temperature, thereby achieving energy saving.

[0068] In this embodiment, the second fan 4 may be located in the middle of the refrigeration space 101, or near the air inlet of the cooling channel 2 within the refrigeration space 101, or away from the air inlet of the cooling channel 2 within the refrigeration space 101. The specific location of the second fan 4 within the refrigeration space 101 is not limited here.

[0069] Furthermore, such as Figure 4As shown, a controller 6 is located below the outer casing 1. The control signal output terminal of the controller 6 is electrically connected to the control signal receiving terminal of the first fan 3 and the control signal receiving terminal of the second fan 4, respectively. In actual use, the working status of the first fan 3 and / or the second fan 4 can be controlled by turning the knob of the controller 6. Of course, more preferably, the working status of the first fan 3 and / or the second fan 4 can be automatically controlled according to the temperature required for the refrigeration environment in the refrigeration space 101. That is, the controller 6 automatically controls the start and stop of the first fan 3 and / or the second fan 4 through the preset temperature control program, thereby controlling the air volume and the start and stop of the fans, and realizing real-time control of the refrigeration environment in the refrigeration space 101.

[0070] In one optional embodiment of this utility model, such as Figure 3 and Figure 5 As shown, the refrigeration device also includes a return channel 5, which has an air inlet and an air outlet. The air inlet of the return channel 5 is connected to the refrigeration space 101, and the air outlet of the return channel 5 is connected to the interior of the freezer body 10, so that the cold air in the refrigeration space 101 returns to the interior of the freezer body 10. Even without the return channel 5, since the outer shell 1 of this invention is not completely sealed, some of the cold air continuously entering the refrigeration space 101 will enter the external environment. However, with the return channel 5, the refrigeration space 101 returns to the freezer body 10 under the drive of the first fan 3 and the second fan 4, thereby forming a circulation of cold air between the interior of the freezer body 10 and the refrigeration space 101, reducing the amount of cold air loss. The air outlet of the cooling channel 2 and the air inlet of the return channel 5 are located at opposite ends of the refrigeration space 101, ensuring that the cold air completely flows through the refrigeration space 101 before returning to the freezer body 10.

[0071] Furthermore, such as Figure 3 and Figure 5As shown, the return channel 5 is configured in the same way as the cooling channel 2, except for its location. The return channel 5 is vertically positioned at at least one apex on the inner wall of the freezer body 10. The specific structure of the return channel 5 is as follows: a second mounting plate 501 with a folded cross-section is provided inside the freezer body 10 near the apex. The second mounting plate 501 extends vertically along its length, and its two opposite edges are sealed to the inner wall of the freezer body 10 near the apex. The second mounting plate 501 and two adjacent inner walls of the freezer body 10 form the four side walls of the return channel 5, thus enclosing a rectangular cross-section return channel 5. This structural arrangement ensures that the return channel 5 is positioned as close as possible to the inner wall of the freezer body 10, avoiding the return channel 5 occupying a large space within the freezer body 10 and ensuring that it does not significantly affect the freezing space within the freezer body 10.

[0072] Specifically, the cooling channel 2 and the return channel 5 are respectively located at two opposite apex corners of the inner wall of the freezer body 10, so that the cooling channel 2 and the return channel 5 can cooperate with the outer shell 1 located at the rear top of the freezer body 10. The cooling channel 2 and the return channel 5 can extend vertically upward to connect with the refrigeration space 101 inside the outer shell 1, so as to ensure that there will be no significant impact on the freezing space inside the freezer body 10, and to ensure that the freezer can be used normally (the storage basket containing items inside the freezer body 10 can be normally put into or taken out through the top opening of the freezer) without being affected.

[0073] In a preferred embodiment of this utility model, such as Figure 3 and Figure 5 As shown, the air outlet of the return channel 5 is located at the bottom of the refrigeration space 101. Since the temperature inside the refrigeration space 101 is generally controlled between 0 and 10°C, which is significantly higher than the temperature inside the freezer body 10, the air outlet position of the return channel 5 is set to directly transport the cold air returning from the refrigeration space 101 to the freezer body 10 near its bottom. This allows for rapid cooling of the cold air returning from the refrigeration space 101 to the freezer body 10, thus avoiding any impact on the freezing environment inside the freezer body 10 and ensuring that both the refrigeration and freezing functions of this invention can be performed normally and stably.

[0074] Furthermore, such as Figure 3 and Figure 5As shown, the air inlet of the return channel 5 is a constricted shape with a gradually decreasing cross-sectional area from top to bottom, which can play a guiding role, so that the cold air in the refrigeration space 101 can be concentrated and enter the return channel 5 and be transported to the freezer body 10, thereby ensuring that the cold air can circulate between the freezer body 10 and the refrigeration space 101.

[0075] In one optional embodiment of this utility model, such as Figures 1 to 5 As shown, the outer shell 1 can be a cuboid or a cuboid-like shape. The top wall and the back wall of the outer shell 1 can be formed by sheet metal forming, while the two side walls located on both sides of the top wall and the back wall can be formed by injection molding. The two side walls after injection molding are respectively assembled and connected to the top wall and the back wall. A first sliding door 102 is provided at the front of the outer shell. The refrigerated space 101 can be opened or closed through the first sliding door 102 so as to take out and put in the items in the refrigerated space 101.

[0076] The first sliding door 102 may be made of, but is not limited to, transparent glass (which may be a double-layered transparent glass door), thereby allowing the items in the refrigerated space 101 to be displayed, enhancing the consumer's user experience, and making it easier to know the sales status of the items so that restocking can be carried out in a timely manner.

[0077] Furthermore, such as Figure 4 As shown, a sandwich cavity is formed within the wall of the outer shell 1, and the sandwich cavity contains insulation material 7 to enhance the insulation capacity of the cold storage space 101 and improve its ability to prevent cold loss. The insulation material 7 may be, but is not limited to, polyurethane foam.

[0078] Furthermore, the thickness of the insulation material 7 can be, but is not limited to, 3.5-4cm.

[0079] In an optional embodiment of this utility model, a temperature probe is installed inside the refrigeration space 101, and a display 8 is installed below the outer casing 1. The detection signal receiving end of the display 8 is electrically connected to the detection signal output end of the temperature probe. The temperature inside the refrigeration space 101 can be detected in real time by the temperature probe, thereby controlling the working state of the first fan 3 and / or the second fan 4 based on the detected temperature information to ensure that the temperature inside the refrigeration space 101 can reach the preset refrigeration temperature.

[0080] Furthermore, the temperature probe is located at the end of the refrigeration space 101 away from the air outlet of the cooling channel 2. Since the temperature in the refrigeration space 101 gradually increases from the end near the air outlet of the cooling channel 2 to the end away from the air outlet of the cooling channel 2, by detecting the area with higher temperature in the refrigeration space 101, as long as the temperature at the end of the refrigeration space 101 away from the air outlet of the cooling channel 2 is within the preset refrigeration temperature range, it can be ensured that the temperature in any area of ​​the refrigeration space 101 will not exceed the refrigeration temperature range. This ensures that the stored items will not deteriorate due to excessively high temperature in the refrigeration space 101, thus ensuring the stable and safe use of the refrigeration space 101.

[0081] Furthermore, vertically, the temperature probe is located in the middle of the refrigeration space 101 (i.e., the temperature probe is set at half the height of the refrigeration space 101). Since there is no cooling source in the refrigeration space 101, while the outside temperature may reach 38°C or higher, and the sinking of cold air will cause a large temperature difference between the upper and lower parts of the refrigeration space 101, setting the temperature probe in the middle of the refrigeration space 101 can ensure that the overall temperature in the refrigeration space 101 reaches the preset refrigeration temperature, thereby improving the accuracy of temperature measurement in the refrigeration space 101.

[0082] like Figure 5 As shown, the refrigeration device of this utility model can transport the cold air (temperature between -23°C and -27°C) inside the freezer body 10 and below the load surface 1001 to the refrigeration space 101 set at the top of the freezer body 10 through the cooling channel 2. Through the suction action of the first fan 3 and the second fan 4, the cold air can be continuously and rapidly circulated between the freezer body 10 and the refrigeration space 101. Even when the ambient temperature is 38°C, the temperature of the refrigeration space 101 can still be maintained between 0°C and 10°C to achieve the refrigeration temperature, thereby achieving the function of refrigeration by utilizing the cold energy inside the freezer body 10.

[0083] The features and advantages of this refrigeration device are:

[0084] The refrigeration unit is located on the top of the freezer body 10. The interior of the freezer body 10 and the refrigeration space 101 within the refrigeration unit are connected by a cooling channel 2 for cold air transfer. The cooling channel 2 delivers cold air from the freezer body 10 to the refrigeration space 101, creating a refrigeration environment within the separate outer shell 1 on top of the freezer body 10. This allows items requiring low-temperature storage but not freezing to be stored in the refrigeration space 101. This not only ensures that the freezer's own freezing function is not affected but also utilizes the cold air within the freezer body 10 to achieve the refrigeration function, integrating freezing and refrigeration functions into one unit, thus enriching the freezer's functionality and application scenarios.

[0085] Implementation Method 2

[0086] like Figures 1 to 5 As shown, the present invention provides a freezer with a refrigeration device. The freezer includes a freezer body 10 and the aforementioned refrigeration device. The refrigeration device is disposed on the top of the freezer body 10 and forms a circulation of cold air inside the freezer body 10 and the refrigeration space 101 inside the refrigeration device.

[0087] Furthermore, such as Figure 1 and Figure 2 As shown, the freezer body 10 has a top opening, and a second sliding door 1002 with a push-pull switch is provided at the top opening of the freezer body; vertically, the refrigeration device is offset from the top opening of the freezer body 10 to ensure that the setting of the refrigeration device will not affect the storage of items inside the freezer body 10, and to ensure that the freezer can be used normally (the storage basket containing items inside the freezer body 10 can be normally put into or taken out through the top opening of the freezer) without being affected.

[0088] Furthermore, the second sliding door 1002 may be made of, but is not limited to, transparent glass.
