Description

Technical Field

[0001] The present application relates to the field of household appliance technology, and in particular to a refrigeration device. Background Art

[0002] When the refrigeration equipment is in use, there is a temperature difference between the cold air flow generated by the evaporator and the air flow inside the cabinet, which will cause frost to form on the surface of the inner tank. Especially when the door is opened and closed frequently, the inner tank at the top of the refrigeration equipment is close to the door body, and frost accumulation is more serious due to the large temperature difference of the air flow and frequent exchange. If the frost is not cleaned in time, the frost layer will continue to thicken and even freeze, making it difficult for users to open and close the door and increasing power consumption.

[0003] The related technology provides a refrigerator with an automatic defrost function. An automatic defrost device is arranged on the inner tank of the refrigerator's cold storage box. The automatic defrost device includes a defrost shovel, a motor and a control device. The control device controls the motor so that the motor drives the defrost shovel to move back and forth along the inner tank to remove the accumulated frost covering the inner tank.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The related technology requires a motor to drive the defrost shovel to achieve the defrosting action. The motor drive increases the energy consumption of the refrigerator, which is not conducive to energy conservation and emission reduction.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0037] Combination Figures 1 to 4 As shown, an embodiment of the present disclosure provides a refrigeration device to reduce energy consumption during the defrosting process of the refrigeration device.

[0038] Optionally, combined Figure 1As shown, the refrigeration equipment includes a cabinet body 10, a door body 20 and a defrost device 30, the cabinet body 10 is provided with an inner tank 11; the door body 20 is openably arranged on the cabinet body 10 and is rotatably connected to the cabinet body 10; the defrost device 30 is arranged on the door body 20, and when the door body 20 rotates relative to the cabinet body 10, the defrost device 30 can move with the door body 20; wherein, when the door body 20 is in a closed state, the defrost device 30 is arranged corresponding to the inner tank 11, and the defrost end of the defrost device 30 extends into the inner tank 11 and faces the wall surface of the inner tank 11 that is prone to frost. During the process of opening or closing the door, the defrost device 30 follows the door body 20 to move in a direction away from or toward the cabinet body 10, driving the defrost end to move to clear the frost accumulated on the wall surface of the inner tank 11 that is prone to frost.

[0039] The refrigeration device is provided with an inner tank at the side, top and bottom, and the wall surface prone to frost includes the inner tank located at the side of the refrigeration device, and / or, the inner tank located at the bottom of the refrigeration device, and / or, the inner tank located at the top of the refrigeration device. The embodiment of the present disclosure mainly uses the defrosting device 30 to clean the frost on the wall surface prone to frost in the inner tank at the top of the refrigeration device. The inner tank 11 mentioned below refers to the inner tank at the top of the refrigeration device.

[0040] It can be understood that the defrosting device 30 provided in the embodiment of the present disclosure can also be used to clean the frost accumulated on the side and bottom inner tank walls of the refrigeration equipment that are prone to frost.

[0041] Combination Figure 3 and Figure 4 As shown, the inner tank 11 includes a first end 111 and a second end 112. Since the inner tank area defined by the first end 111 and the second end 112 is close to the door body 20, the air flow temperature difference is large and it is easy to frost, so the first end 111 and the second end 112 define a wall surface that is easy to frost.

[0042] When the door is closed, the defrosting end of the defrosting device 30 goes deep into the inner tank 11 and faces the wall surface that is prone to frost. When the defrosting device 30 follows the door body 20 to move toward or away from the cabinet body 10, the defrosting end of the defrosting device 30 moves between the first end 111 and the second end 112, so that the frost on the wall surface that is prone to frost can be scraped off. Figure 3 and Figure 4 The A in the figure indicates frost accumulation.

[0043] Since users need to frequently open and close the door 20 to take out and put items, each time the door is opened, the defrosting device 30 rotates out of the cabinet 10 to achieve a defrosting process, so that the accumulated frost will not become thicker and thicker due to long-term existence, causing difficulty in opening and closing the door.

[0044] It is understandable that, during the process of closing the door of the refrigeration equipment, the defrosting end of the defrosting device 30 faces the wall surface of the inner tank 11 that is prone to frost, so the frost can be removed when the door is closed. However, the frost on the inner tank 11 is generated when the door is closed, and the frost can be removed by opening the door. Therefore, during the process of closing the door, the frost on the wall surface that is prone to frost has been basically removed, that is, the defrosting device 30 mainly defrosts during the process of opening the door.

[0045] By utilizing the process of opening and closing the door, the accumulated frost on the inner tank 11 can be removed by the defrost device 30, and there is no need to use a driving device to drive the defrost device for defrosting, thereby reducing energy consumption.

[0046] Optionally, combined Figure 2 As shown, the defrost device 30 includes a defrost shovel 31, which is arranged on the door body 20. In the closed state, the defrost shovel 31 extends into the inner tank 11 and its defrost end faces the wall surface of the inner tank 11 that is prone to frost.

[0047] The defrosting end of the defrosting shovel 31 is arranged toward the inner container 11 . When the door is opened or closed, the defrosting shovel 31 moves with the door body 20 to remove the accumulated frost attached to the surface of the inner container 11 .

[0048] Optionally, the defrost shovel 31 has a scraping portion 311 extending along the frost-prone wall surface of the inner tank 11, and the scraping portion 311 is arranged opposite to the frost-prone wall surface so as to scrape off the frost accumulated on the frost-prone wall surface covered by the moving path during the movement with the door body 20.

[0049] When the door is closed, the scraping portion 311 is arranged corresponding to the first end portion 111, and the distance between the scraping portion 311 and the inner container 11 is between 0.5 mm and 2 mm. Because when the scraping portion 311 abuts against the inner container 11 and the distance is 0, it is not conducive to the movement of the defrosting shovel 31 relative to the inner container 11, and when the gap between the scraping portion 311 and the inner container 11 is too large, it will lead to incomplete defrosting.

[0050] It is understandable that, in the closed state, the gap between the scraping portion 311 and the inner container 11 is set according to the actual frosting situation.

[0051] Optionally, combined Figure 2 As shown, the defrost shovel 31 further has a connecting wall 312 which is arranged in a vertical direction and connected to the shoveling portion 311 , and the connecting wall 312 is connected to the door body 20 .

[0052] The scraping portion 311 is connected to the connecting wall 312, and the connecting wall 312 is arranged in the vertical direction so that the defrosting shovel 31 is perpendicular to the inner container 11. In this way, when the defrosting shovel 31 moves away from the cabinet 10, the contact area between the defrosting shovel 31 and the accumulated frost is increased, which is conducive to removing the accumulated frost.

[0053] Optionally, the defrosting device 30 further includes a frost receiving box 32 , which is disposed on the door body 20 and below the defrosting shovel 31 .

[0054] The frost collecting box 32 is arranged below the defrost shovel 31, and the frost collecting box 32 can move synchronously with the defrost shovel 31. In this way, when the defrost shovel 31 clears the frost accumulated in the inner tank 11 during the process of opening or closing the door, the accumulated frost will directly fall into the frost collecting box 32, preventing the accumulated frost from falling into the inside of the refrigeration equipment.

[0055] Optionally, the frost collecting box 32 is detachably connected to the door body 20 .

[0056] Optionally, one of the frost collecting box 32 and the door body 20 is provided with a snap-in groove (not shown in the figure), and the other is provided with an inserting plate, which is inserted into the snap-in groove to connect the frost collecting box 32 with the door body 20.

[0057] Optionally, there are multiple snap-in grooves, which are arranged in sequence along the height direction of the door body 20 .

[0058] By providing a plurality of clamping slots with different heights and inserting the inserting plates into the clamping slots with different heights, the height of the frost collecting box 32 can be adjusted to meet different needs of users.

[0059] The frost collecting box 32 is detachably connected to the door body 20. When a lot of frost is accumulated in the frost collecting box 32, the frost collecting box 32 can be taken out from the door body 20 at any time to clean the accumulated frost.

[0060] Optionally, the frost collecting box 32 is fixedly connected to the door body 20 .

[0061] Optionally, the frost collecting box 32 and the door body 20 are provided with bolt holes correspondingly, so as to fix the frost collecting box 32 to the door body 20 by fastening bolts.

[0062] The frost receiving box 32 is fixedly connected to the door body 20, so as to ensure the connection strength of the frost receiving box 32 and prevent the frost receiving box 32 from falling off due to excessive frost accumulation.

[0063] When there is a lot of frost accumulated in the frost receiving box 32, the frost accumulated in the frost receiving box 32 can be manually removed.

[0064] Optionally, the frost receiving box 32 is disposed between the door body 20 and the defrost shovel 31 , and is connected to the defrost shovel 31 .

[0065] The frost receiving box 32 is disposed between the door body 20 and the defrost shovel 31 , that is, the frost receiving box 32 is disposed on a side of the defrost shovel 31 facing away from the cabinet body 10 .

[0066] As can be seen from the above, the defrosting process of the refrigeration equipment is mainly in the process of opening the door. When the door is opened, the door body 20 rotates in the direction away from the cabinet body 10, driving the defrost shovel 31 to move relative to the inner tank 11, and rotates out of the cabinet body 10 along the inner tank 11, so the falling position of the accumulated frost is between the defrost shovel 31 and the door body 20. The frost collecting box 32 is arranged between the door body 20 and the defrost shovel 31. On the one hand, it can catch the accumulated frost falling from the inner tank 11, and on the other hand, it can reduce the size of the frost collecting box 32, so as to avoid the frost collecting box 32 from being too long and deeply inserted into the cabinet body 10, occupying the space of the cabinet body 10.

[0067] Optionally, the frost receiving box 32 is connected to the connecting wall 312 so that the defrost shovel 31 is connected to the door body 20, so that the door body 20 drives the defrost shovel 31 to move for defrosting.

[0068] Optionally, the connecting wall 312 is fixedly connected to a side wall of the frost receiving box 32 facing the defrost shovel 31 , so that the defrost shovel 31 is fixedly connected to the frost receiving box 32 .

[0069] Optionally, the defrosting shovel 31 and the frost receiving box 32 are an integrally formed structure.

[0070] The frost receiving box 32 is extended toward the side wall of the cabinet 10 along the direction of the inner container 11 to form a defrosting shovel 31 .

[0071] The frost receiving box 32 and the defrost shovel 31 are integrally formed, which ensures the connection strength between the defrost shovel 31 and the frost receiving box 32 and prevents the frost receiving box 32 and the defrost shovel 31 from being broken during the defrosting process.

[0072] When the frost collecting box 32 is detachably connected to the door body 20, it can be known from the above that by providing a plurality of clamping grooves of different heights and inserting the plug plates into the clamping grooves of different heights, the height of the frost collecting box 32 can be adjusted. The frost collecting box 32 is integrally formed with the defrosting shovel 31, so the gap between the defrosting shovel 31 and the inner tank 11 can be adjusted, so that the user can adjust the height of the defrosting device 30 according to the thickness of the accumulated frost.

[0073] Optionally, the refrigeration device further includes a drainage channel 50 , which is disposed on the door body 20 and communicates with the frost collecting box 32 .

[0074] The frost receiving box 32 receives the accumulated frost removed by the defrosting shovel 31. The drainage channel 50 is connected to the frost receiving box 32. When the accumulated frost in the frost receiving box 32 melts, it can flow out along the drainage channel 50.

[0075] Optionally, the drainage channel 50 is arranged along the height direction of the door body 20 .

[0076] The drainage channel 50 is arranged along the height direction of the door body 20 , so that the water after the frost is melted can flow out of the frost receiving box 32 along the drainage channel 50 under the action of its own gravity.

[0077] Optionally, the frost collecting box 32 is provided with a drain port; the drain channel 50 includes a first end 51 and a second end 52 sequentially arranged along its height direction, the first end 51 is connected to the drain port, and the second end 52 passes through the door body 20 .

[0078] The frost collecting box 32 is provided with a drain outlet, and the drain outlet is communicated with the first end 51 of the drain channel 50, and the second end 52 runs through the door body 20, so that water can flow through the drain outlet and the first end 51 of the drain channel 50 in sequence, and flow out of the door body 20 from the second end 52 of the drain channel 50, thereby avoiding water accumulation in the refrigeration equipment.

[0079] Optionally, the refrigeration device further comprises a water receiving box, which is arranged below the door body 20 and corresponds to the second end 52 of the drainage channel 50. When the defrost water flows out of the door body 20 along the second end 52 of the drainage channel 50, it directly flows into the frost receiving box to collect the defrost water.

[0080] Optionally, the door body 20 includes an outer shell and an inner shell of the door body, and the outer shell and the inner shell of the door body define a foaming cavity, and the drainage channel 50 is arranged in the foaming cavity.

[0081] The temperature inside the refrigeration equipment is relatively low. After the frost in the frost receiving box 32 melts, when the accumulated water is discharged to the outside of the door body 20 along the drainage channel 50 , the accumulated water is easy to freeze in the drainage channel 50 , resulting in poor drainage.

[0082] A foaming cavity is defined between the shell and the inner liner of the door body, and a foaming material is injected into the foaming cavity of the refrigeration device to play a role in heat preservation. The drainage channel 50 is arranged in the foaming cavity to avoid poor drainage caused by ice in the drainage channel 50.

[0083] Optionally, combined Figure 2 As shown, the refrigeration device further includes a heating device 60 , which is disposed in the frost collecting box 32 .

[0084] Optionally, the heating device 60 includes a heating wire, and the heating wire is disposed in the frost collecting box 32 .

[0085] Optionally, the heating wires are evenly arranged on the bottom wall of the frost collecting box 32 , and / or the heating wires are evenly arranged on the side walls of the frost collecting box 32 .

[0086] When the defrosting shovel 31 removes the frost on the inner container 11 , the frost falls into the frost receiving box 32 , and the heating device 60 is started to melt the frost. The melted frost flows out of the door body 20 along the drainage channel 50 .

[0087] The power of the heating wire can be selected according to actual needs. When a high-power heating wire is selected, the melting time of accumulated frost is accelerated.

[0088] Optionally, the refrigeration device further comprises a terminal heating device, and the terminal heating device is arranged at the defrosting terminal of the defrosting device.

[0089] When the refrigeration equipment has not been opened or closed for a long time, resulting in thick frost and difficulty in opening the door, the terminal heating device is controlled to heat to melt and loosen the frost on the inner tank 11 before opening the door. During the door opening process, the defrosting device (for example, the defrosting shovel 31) is used to remove the frost.

[0090] Optionally, the refrigeration device further comprises a frost thickness temperature sensor and a controller, wherein a control output terminal of the controller is electrically connected to the terminal heating device, and a signal input terminal is electrically connected to the frost thickness temperature sensor.

[0091] The frost thickness temperature sensor is arranged in the inner tank 11 for sensing the frost thickness of the inner tank 11 , and the controller is used for controlling the opening of the terminal heating device according to the frost thickness detected by the frost thickness temperature sensor.

[0092] Optionally, the controller controls the terminal heating device according to the frost thickness detected by the frost thickness temperature sensing head, including:

[0093] The controller obtains the frost thickness c detected by the frost thickness temperature sensor;

[0094] If c < 2mm, the controller controls the end heating device to stop working;

[0095] If c≥2mm, the controller controls the end heating device to turn on.

[0096] It is understandable that the controller controls the start and stop of the terminal heating device based on the standard of frost thickness c being 2 cm. The standard of frost thickness c here can be set according to actual conditions.

[0097] Optionally, the refrigeration equipment also includes a gravity sensor 70, which is arranged at the bottom of the frost box 32 to detect the weight of frost accumulated in the frost box 32; the control output end of the controller is electrically connected to the heating device 60, and the signal input end is electrically connected to the gravity sensor 70; the controller is used to control the heating time of the heating device 60 according to the weight of frost accumulated in the frost box 32 detected by the gravity sensor 70.

[0098] When the door is open, the defrost shovel 31 clears the accumulated frost, and the accumulated frost falls into the frost collecting box 32. The controller controls the gravity sensor 70 to work. The gravity sensor 70 detects the weight of the accumulated frost and transmits the weight signal to the controller. The controller controls the heating time of the heating device 60 according to the weight of the accumulated frost to avoid insufficient defrosting of the accumulated frost due to a short heating time of the heating device 60, or increased energy consumption due to too long heating time of the heating device 60.

[0099] The method by which the gravity sensor 70 detects the weight of accumulated frost is as follows:

[0100] When the door is closed, the defrost shovel 31 does not perform defrosting work and there is no frost accumulated in the frost box 32. The gravity sensor 70 detects that the weight of the frost box 32 is m1. When the door is open, the defrost shovel 31 completes the defrosting work and the accumulated frost falls into the frost box 32. At this time, the gravity sensor 70 is used again to detect that the weight of the frost box 32 is m2. By using m2-m1, the weight m of the accumulated frost in the frost box 32 can be obtained.

[0101] Optionally, the controller controls the heating device 60 according to the weight of accumulated frost, including:

[0102] The controller obtains the frost weight m detected by the gravity sensor 70;

[0103] If m=0, the controller controls the heating device 60 to stop working;

[0104] If m>0, the controller controls the heating device 60 to turn on.

[0105] Optionally, when the controller determines that the frost accumulation weight m>0, controlling the heating device 60 to start the heating time includes:

[0106] According to the heat calculation formula Q = cm△T, the defrosting heat is obtained;

[0107] According to the time calculation formula t=Q / P, the heating time required for defrosting is obtained.

[0108] Among them, P (W) is the power of the heating wire; △T is the change in temperature of the frost during the defrosting process, usually taking a value of 18; c is the specific heat capacity of ice 2100 J / (KG.℃).

[0109] For example, a heating wire with a power of 1100W is set in the frost receiving box 32. When the weight of the accumulated frost in the frost receiving box 32 is 0.5kg, the defrosting heat Q=cm△T=2100×0.5×18=18900J is obtained. According to the heating time calculation formula t=Q / P=18900 / 1100=17.18s, when the heating wire of 1100W is used to heat the accumulated frost and the weight of the accumulated frost is 0.5kg, the required defrosting time is 17.18s.

[0110] The refrigerator provided by the embodiment of the present disclosure can achieve the following technical effects:

[0111] The inner tank 11 at the top of the refrigeration device is prone to frost accumulation. The defrost shovel 31 is provided on the door body 20 and can move in a direction toward or away from the cabinet body 10 when following the rotation of the door body 20 relative to the cabinet body 10. When the refrigeration device is in a closed state, the defrost shovel 31 is provided toward the inner tank 11. When the defrost shovel 31 follows the door body 20 and moves in a direction away from or toward the cabinet body 10 during the door opening or closing process, the scraping portion 311 can scrape off the frost accumulated on the inner tank 11. The defrost shovel 31 is connected to the frost receiving box 32. The frost removed by the defrost shovel 31 can fall into the frost receiving box 32. The heating device 60 controls the heating time according to the weight of the frost accumulated in the frost receiving box 32 so that the frost is melted. The water after the frost is melted flows out of the door body 20 from the drainage channel 50. By opening or closing the door, the defrost shovel 31 can be used to remove the frost on the inner tank 11. There is no need to use a driving device to drive the defrost shovel 31 for defrosting. The process of removing the frost does not increase energy consumption, thereby achieving energy conservation and emission reduction. In addition, when the heating device 60 melts the frost, the heating time of the heating device 60 is controlled according to the weight of the frost to prevent excessive heating from increasing energy loss. Therefore, energy consumption can be reduced and energy conservation and emission reduction can be achieved throughout the defrosting process of the refrigeration equipment.
