Technical Field

[0001] This utility model belongs to the field of refrigeration technology, and specifically provides a refrigeration and freezing device. Background Technology

[0002] Currently, some refrigeration and freezing equipment is equipped with fans to drive cold air to cool hot pots. However, after the cold air flows out of the air outlet, the airflow is chaotic due to the lack of an effective guiding structure, resulting in low cooling efficiency. Utility Model Content

[0003] One objective of this invention is to solve the problem of low cooling efficiency of hot pots in refrigeration and freezing equipment.

[0004] To achieve the above objectives, this utility model provides a refrigeration and freezing device, comprising:

[0005] The enclosure defines a refrigeration space, a first air duct, a cookware placement space, and a return air duct that are connected end to end to form a gas circuit. The cookware placement space is used to place a hot pot. The first air duct has air outlets formed on the left and right walls of the cookware placement space, respectively.

[0006] An evaporator, arranged within the refrigeration space, is used to cool the air within the refrigeration space;

[0007] A cookware cooling fan is used to drive cold air in the cooling space to blow directly onto the hot pot through the air outlet to cool the hot pot;

[0008] The left and right walls of the cookware placement space are respectively provided with concave air guide grooves, and the air outlet is formed at the top of the air guide grooves.

[0009] Optionally, the air guide channel is provided with an air guide slope below the air outlet, and the air guide slope is inclined from top to bottom toward the space where the cookware is placed, so as to disperse the cold air blown out from the air outlet.

[0010] Optionally, the angle between the air guide slope and the pot placement space can be selected from any value between 100° and 130°.

[0011] Optionally, the air outlet extends in a strip shape along the front-rear direction of the refrigeration and freezing equipment.

[0012] Optionally, the distance between the air outlet and the bottom wall of the cookware placement space is selected from any value between 70mm and 106mm.

[0013] Optionally, the distance between the air outlet and the bottom wall of the cookware placement space is selected from any value between 79mm and 97mm.

[0014] Optionally, the number of air outlets is an integer multiple of 2, and they are evenly distributed on the left and right walls of the cookware placement space.

[0015] Optionally, the cross-sectional shape of the first air duct is rectangular, and the long side of the rectangle is parallel to the vertical direction.

[0016] Optionally, the aspect ratio of the first air duct cross-section is selected from any value between 10.4 and 15.6.

[0017] Optionally, the refrigeration and freezing equipment is a refrigerator.

[0018] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by providing concave air guide grooves on the left and right walls of the cookware placement space, and providing an air outlet at the top of the air guide grooves, the air guide grooves direct the airflow blown out of the air outlets to the cookware, thereby improving the cooling efficiency of the cookware.

[0019] Furthermore, by setting an air guide slope below the air outlet of the air guide channel, and the air guide slope is inclined from top to bottom toward the pot placement space, so that the cold air blows onto the bottom wall of the pot placement space, thereby dispersing the cold air blown out from the air outlet, the hot pot placed in the space can be cooled more evenly, preventing local overheating or overcooling.

[0036] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0037] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0039] like Figure 1 As shown, in some embodiments of this utility model, the refrigerator / freezing equipment 010 has a storage compartment 150 defined inside the cabinet 100, and the door 900 can open or close the storage compartment 150. The storage compartment 150 is divided by a partition 600 into a pot placement space 130 for placing a hot pot 002.

[0040] In real-life scenarios, the hot pot 002 after cooking is often quite hot. Placing it directly in a regular refrigerator / freezer 010 will not only cause a sudden increase in the internal temperature of the equipment, affecting the storage effect of other items, but may also damage internal components due to the high temperature. To quickly cool the hot pot 002, this invention sequentially arranges a cooling space 110, a first air duct 120, a pot placement space 130, and a return air duct 140 connected end-to-end to form a gas circuit within the housing 100. This allows for independent cold air blowing onto the hot pot 002 within the pot placement space 130, improving the cooling efficiency of the hot pot 002.

[0041] To achieve the above objectives, those skilled in the art may, as needed, limit the cookware storage space 130 to the cabinet 100, or limit the cookware storage space 130 to a space independent of the storage room 150.

[0042] like Figure 1As shown, a refrigeration space 110 is provided at the back of the refrigeration and freezing equipment 010. An evaporator 200 and a refrigeration fan 700 are installed within the refrigeration space 110. The evaporator 200 is used to cool the air within the refrigeration space 110, and the refrigeration fan 700 is used to blow the air from the refrigeration space 110 into the entire storage compartment 150 through a second air duct 160. The cold air then returns through the return air duct 140 at the bottom of the storage compartment 150. The dashed arrows in the figure indicate the airflow path.

[0043] It should be noted that, Figure 1 This is merely an illustrative representation of the cold air circulation path. In practical applications, those skilled in the art can make appropriate adjustments to the cold air circuit as needed.

[0044] Specifically, this invention provides a first air duct 120 between the cooling space 110 and the cookware placement space 130, and a cookware cooling fan 300 is installed in the first air duct 120. When it is necessary to cool the hot pot 002 in the cookware placement space 130, the cookware cooling fan 300 can drive the cold air in the cooling space 110 to enter the cookware placement space 130 through the first air duct 120, thereby specifically and quickly cooling the hot pot 002, so that the hot pot 002 can reach a suitable temperature more quickly and reduce the temperature impact on other areas.

[0045] In this utility model, hot pot 002 refers to a pot with a high temperature, such as a pot containing hot rice, hot dishes, etc.

[0046] like Figure 2 As shown, in some embodiments of this utility model, the first air duct 120 may include a left branch 121 and a right branch 122. The left air outlet 123 of the left branch 121 is formed on the left side wall 131 of the cookware placement space 130, and the right air outlet 124 of the right branch 122 is formed on the right side wall of the cookware placement space 130 (not shown in the figure). The left air outlet 123 and the right air outlet 124 are located in the middle of the cookware placement space 130 in the front-back direction. The cookware cooling fan 300 drives the cold air in the cooling space 110 to blow directly onto the hot pot 002 through the left air outlet 123 and the right air outlet 124 to cool the hot pot 002.

[0047] Those skilled in the art will understand that the arrangement of the left branch 121 and the right branch 122, as well as the placement of the air outlets (left air outlet 123 and right air outlet 124) in the middle, enables cold air to be blown evenly and directly onto the hot pot 002, ensuring that all parts of the hot pot 002 are effectively cooled.

[0048] like Figure 3 and Figure 4As shown, the left branch 121 and the right branch 122 are each L-shaped, so that the first air duct 120 is U-shaped as a whole, surrounding the rear, left and right sides of the pot placement space 130.

[0049] In some embodiments of this utility model, the left branch 121 and the right branch 122 are perpendicular to the vertical direction.

[0050] In some embodiments of this utility model, the cross-sectional shape of the first air duct 120 is rectangular, and the long side of the rectangle is parallel to the vertical direction. This can reduce the thickness of the first air duct 120, thereby minimizing the thickness of the shell of the refrigeration and freezing equipment 010.

[0051] In some embodiments of this utility model, the aspect ratio of the cross-section of the first air duct 120 is selected from any value between 10.4 and 15.6. For example, the aspect ratio of the cross-section of the first air duct 120 can be 10.4, 13, and 15.6, etc.

[0052] Furthermore, the aspect ratio of the cross-section of the first air duct 120 is selected from any value between 12 and 14. For example, the aspect ratio of the cross-section of the first air duct 120 can be 12, 12.5, and 14, etc. Setting the aspect ratio of the cross-section of the first air duct 120 to the above values ​​can optimize the air velocity and flow rate within the air duct, ensuring air delivery capacity while making the distribution of cold air within the air duct more reasonable, thereby further improving cooling efficiency.

[0053] like Figure 4 As shown, the air inlet of the first air duct 120 is formed at the junction of the left branch 121 and the right branch 122. The cookware cooling fan 300 is set at the air inlet, so that the left branch 121 and the right branch 122 are symmetrically arranged. The flow path length from the cookware cooling fan 300 to the left air outlet 123 and to the right air outlet 124 is the same, which can ensure that the flow rate and wind speed of the cold air blown from the left and right air outlets 124 are relatively uniform. This allows for more uniform cooling of the hot pot 002 in the cookware placement space 130, avoiding local cooling that is too fast or too slow, and improving the consistency of the cooling effect.

[0054] like Figure 3 As shown, the first air duct 120 and the centrifugal fan 310 can be fitted together on the side of the inner liner 170 away from the storage compartment 150, that is, the first air duct 120 and the centrifugal fan 310 can be installed in the insulation layer of the refrigeration and freezing equipment 010. The air inlet of the centrifugal fan 310 faces the rear of the refrigeration and freezing equipment 010, and a refrigeration space 110 (not shown in the figure) is correspondingly provided on the side of the centrifugal fan 310 away from the inner liner 170.

[0055] It should be noted that, Figure 3 for Figure 1A specific implementation scheme is shown in the schematic diagram.

[0056] like Figure 3 and Figure 4 As shown, the cookware cooling fan 300 can be a centrifugal fan 310. The angle between the rotation axis of the centrifugal fan 310 and the horizontal plane is less than or equal to 20°, so that the airflow blown by the fan can be transported more horizontally, effectively reducing energy loss and airflow deviation caused by airflow rising or falling, thereby improving the cooling efficiency of the hot pot 002.

[0057] like Figure 1 As shown, in some embodiments of the present invention, the centrifugal fan 310 is located between the refrigeration space 110 and the cookware placement space 130, and the rotation axis of the centrifugal fan 310 is parallel to the horizontal plane.

[0058] In addition, those skilled in the art can, as needed, make the angle between the rotation axis of the centrifugal fan 310 and the horizontal plane any feasible value such as 3°, 5°, 12°, 18°, 20°, etc.

[0059] like Figure 5 As shown, the refrigeration and freezing equipment 010 also includes a fan mounting base 800. The fan mounting base 800 includes a fixing part 810 fixedly connected to the side wall 125 of the first air duct 120, an air guide part 820 communicating with the first air duct 120, and a fan mounting part 830 for mounting a centrifugal fan 310. The air guide part 820 extends vertically so that the centrifugal fan 310 is located on the upper side of the first air duct 120.

[0060] Those skilled in the art will understand that the structural design of the fan mounting base 800 makes the centrifugal fan 310 more securely installed. Furthermore, the air guide section 820 extends vertically and connects to the first air duct 120, enabling cold air to enter the air duct more smoothly and improving air delivery efficiency. Simultaneously, the centrifugal fan 310's location on the upper side of the air duct also reduces the thickness of the refrigeration and freezing equipment 010's casing 100 in the front-to-back direction.

[0061] Continue reading Figure 5 In some embodiments of this utility model, the fixing part 810 is provided with a through hole 801 and the box body 100 is provided with a threaded hole (not shown in the figure) so that the screw can pass through the through hole 801 and be tightened into the threaded hole, thereby fixing the fixing part 810 to the box body 100.

[0062] Continue reading Figure 5 The width of the bottom of the air guide 820 gradually expands towards the fixing part 810, and forms the air outlet 840 of the fan mounting base 800 at the position where the expansion is the largest, for connection with the first air duct 120.

[0063] In some embodiments of this utility model, the fan mounting part 830 is plugged into the centrifugal fan 310, which facilitates the installation and disassembly of the centrifugal fan 310, makes it convenient to maintain and repair the fan, and reduces the maintenance cost of the equipment.

[0064] like Figure 6 and Figure 7 As shown, both the left air outlet 123 and the right air outlet 124 are strip-shaped openings extending in the front-to-back direction. These strip-shaped air outlets (left air outlet 123 and right air outlet 124) can blow out strip-shaped airflow, ensuring both airflow speed and airflow area, resulting in more even distribution of cool air and improved cooling efficiency. Furthermore, the strip-shaped openings are less likely to be completely blocked by items in the storage compartment 150, preventing airflow from being unable to escape from either the left air outlet 123 or the right air outlet 124.

[0065] Continue reading Figure 6 and Figure 7 The cookware placement space 130 shown has recessed air guide grooves 134 on its left side wall 131 and right side wall, with air outlets (left air outlet 123 and right air outlet 124) formed at the top of the air guide grooves 134. The air guide grooves 134 guide the flow of cold air and converge the airflow from the air outlets (left air outlet 123 and right air outlet 124), making the cold air more concentrated and improving the cooling efficiency.

[0066] Continue reading Figure 6 and Figure 7 The air guide duct 134 has an air guide slope 135 below the air outlets (left air outlet 123, right air outlet 124). The air guide slope 135 slopes downwards towards the cookware placement space 130. The airflow from the air outlets (left air outlet 123, right air outlet 124) is changed in direction and dispersed by the air guide slope 135. In this way, the airflow can form a more uniform flow field distribution within the cookware placement space 130, avoiding cold air from being concentrated in one area. This allows for more uniform cooling of the hot pot 002 or other items placed in the space, preventing local overheating or overcooling, and improving the cooling effect and efficiency.

[0067] In some embodiments of this utility model, the included angle between the air guide slope 135 and the bottom wall 133 of the cookware placement space 130 is selected from any value between 100° and 130°. For example, the included angle between the air guide slope 135 and the bottom wall 133 of the cookware placement space 130 can be 100°, 115°, and 130°, etc.

[0068] Furthermore, the angle between the air guide slope 135 and the bottom wall 133 of the cookware placement space 130 is selected from any value between 110° and 120°. For example, the angle between the air guide slope 135 and the bottom wall 133 of the cookware placement space 130 can be 110°, 116°, and 119°, etc.

[0069] Those skilled in the art will understand that a suitable angle allows the guide slope 135 to better guide the flow direction of cold air, ensuring that the cold air is in full contact with the hot pot 002.

[0070] In some embodiments of this utility model, the distance between the air outlet (left air outlet 123, right air outlet 124) and the bottom wall 133 of the cookware placement space 130 is selected from any value between 70mm and 106mm. For example, the distance between the air outlet (left air outlet 123, right air outlet 124) and the bottom wall 133 of the cookware placement space 130 can be 70mm, 90mm, and 106mm, etc.

[0071] Furthermore, the distance between the air outlet (left air outlet 123, right air outlet 124) and the bottom wall 133 of the cookware placement space 130 is selected from any value between 79mm and 97mm. For example, the distance between the air outlet (left air outlet 123, right air outlet 124) and the bottom wall 133 of the cookware placement space 130 can be 79mm, 85mm, and 97mm, etc.

[0072] Specifically, the distance between the air outlets (left air outlet 123, right air outlet 124) and the bottom wall 133 of the cookware placement space 130 is limited to 70mm to 106mm (preferably 79mm to 97mm). Combined with the guide slope 135 to change the airflow direction, this allows for precise control of the range of collision and diffusion of cold air with the bottom wall 133. Within this distance range, after the cold air is blown out from the air outlets (left air outlet 123, right air outlet 124), it is guided to the bottom wall 133 by the guide slope 135. This allows the airflow to bounce off the bottom wall 133 and then diffuse more fully and evenly upwards to the entire cookware placement space 130, preventing insufficient airflow due to distance being too close or too far, and ensuring effective cooling of all areas within the space.

[0073] Those skilled in the art will understand that a reasonable distance, combined with the characteristics of the inclined plane 135 that disperses cold air, creates a uniform flow field distribution, allowing the cold air to fully contact the surface of the hot pot 002. The cold air is no longer concentrated on a single area, but rather surrounds the hot pot 002 from multiple directions, significantly improving cooling efficiency, shortening the cooling time of the hot pot 002, and reducing the impact of excessive local temperature differences on the hot pot 002 and other items.

[0074] In some embodiments of this utility model, the number of air outlets is an integer multiple of 2, and they are evenly distributed on the left side wall 131 and right side wall of the pot placement space 130. This allows the cold air to act more evenly on the hot pot 002, ensuring that all parts of the hot pot 002 are effectively cooled. For example, there are four air outlets: two left air outlets 123 are provided on the left side wall 131, and two right air outlets 124 are provided on the right side wall.

[0075] like Figure 6 As shown, the refrigeration and freezing equipment 010 is also equipped with a temperature measuring device 400 and an indicator light 500. The temperature measuring device 400 is installed on the side wall of the pot placement space 130 to detect the temperature of the hot pot 002. The indicator light 500 is used to indicate the working status of the pot cooling fan 300, so that the user can understand the cooling status of the hot pot 002 in real time and intuitively.

[0076] In some embodiments of this invention, the temperature measuring device 400 is an infrared sensor. For example, after the hot pot 002 is placed in the cookware placement space 130, the infrared sensor detects the heat source, and the indicator light 500 turns orange. The infrared sensor sends a signal to the controller, which then controls the centrifugal fan 310 to operate, causing the indicator light 500 to flash blue. The infrared sensor measures the temperature of the hot pot 002 in real time, and the controller accordingly controls the airflow of the centrifugal fan 310 in real time. Once the hot pot 002 reaches the set temperature, the indicator light 500 remains constantly lit in blue.

[0077] In some embodiments of this utility model, the controller is equipped with an AI smart chip.

[0078] Continue reading Figure 6 In some embodiments of this utility model, the indicator light 500 is strip-shaped. The indicator light 500 extends along the front-to-back direction of the refrigeration and freezing equipment 010, so that it is not easily blocked by items in the cookware placement space 130, making it easy for the user to see the light status of the indicator light 500.

[0079] Continue reading Figure 6 In some embodiments of this utility model, the indicator light 500 is positioned above the air outlets (left air outlet 123, right air outlet 124), and the distance between the indicator light 500 and the air outlets (left air outlet 123, right air outlet 124) is less than or equal to 30mm. For example, the distance between the indicator light 500 and the air outlets (left air outlet 123, right air outlet 124) can be 20mm, 25mm, or 30mm, etc.

[0080] Furthermore, the distance between the indicator light 500 and the air outlet (left air outlet 123, right air outlet 124) is less than or equal to 20mm. For example, the distance between the indicator light 500 and the air outlet (left air outlet 123, right air outlet 124) can be 10mm, 15mm, and 19mm, etc.

[0081] Continue reading Figure 6 In some embodiments of this utility model, the air outlets (left air outlet 123, right air outlet 124) extend in the same direction as the indicator light 500.

[0082] Continue reading Figure 6 In some embodiments of this utility model, the temperature measuring device 400 is disposed on one side of the indicator light 500 along its length.

[0083] In some embodiments of this utility model, the number of indicator lights 500 is an integer multiple of 2, and they are evenly distributed on opposite side walls of the cookware placement space 130. For example, there can be four indicator lights 500, with two indicator lights 500 on the left side wall 131 of the cookware placement space 130 and two indicator lights 500 on the right side wall of the cookware placement space 130. This ensures that users can clearly see the status of the indicator lights 500 regardless of whether they approach the refrigeration and freezing equipment 010 from the left, right, or oblique side, effectively avoiding the problem of not being able to obtain equipment operation information due to obstructed viewing angles, allowing users to keep track of the working status of the cookware cooling fan 300 and the cooling progress of the hot pot 002 at any time.

[0084] Meanwhile, multiple indicator lights 500 display the same information simultaneously, serving as a means of mutual verification. If one indicator light 500 malfunctions, the others will still function normally, preventing users from misjudging the equipment's operating status due to a single indicator light 500 failure and enhancing the reliability and stability of the equipment's operating status feedback.

[0085] In some embodiments of this invention, the number of temperature measuring devices 400 is an integer multiple of two, and they are evenly distributed on opposite side walls of the cookware placement space 130. For example, there are four temperature measuring devices 400: two on the left side wall 131 and two on the right side wall of the cookware placement space 130. This allows for real-time temperature detection at different locations within the area, avoiding temperature data deviations caused by single-point temperature measurement. Obtaining temperature information of the hot pot 002 and its surrounding environment from multiple dimensions provides a more comprehensive and accurate reflection of the actual temperature of the cookware placement space 130, offering reliable data support for precise control of the cooling process.

[0086] like Figure 1As shown, in some embodiments of this utility model, a transparent observation window 910 is provided on the door 900. Users can see the status of the indicator light 500 and know the working status of the cookware cooling fan 300 and the cooling progress of the hot pot 002 through the observation window 910 without opening the door 900, significantly reducing the need to frequently open the door to check the equipment's operating status. This effectively prevents cold air leakage caused by opening the door 900, maintaining a low-temperature environment in the cookware placement space 130 and the storage compartment 150, ensuring the storage effect of other stored items, while also reducing equipment energy consumption and improving the energy efficiency ratio of the refrigeration and freezing equipment 010.

[0087] In summary, by setting a left air outlet on the left side wall of the pot placement space and a right air outlet on the right side wall of the pot placement space, this utility model enables cold air to blow directly onto both sides of the hot pot, thereby improving the cooling efficiency of the hot pot.

[0088] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments.
