Description

Technical Field

[0001] The present application relates to the field of household appliance technology, and in particular to a dual-temperature cabinet. Background Art

[0002] A dual-temperature cabinet usually includes a cold cabinet or a warm cabinet. A heating device is installed in the warm cabinet or a cooling device is installed in the cold cabinet to heat or cool the cabinet space. To improve the cooling effect or heating effect of the dual-temperature cabinet, it is necessary to fully transfer the cold or heat to the cabinet space.

[0003] In the related art, a fan, an air duct and an air outlet are arranged in the side wall of the dual-temperature cabinet. The fan is arranged corresponding to the refrigeration device and / or the heating device, and the air duct is connected to the air outlet. The fan drives the cold air flow or the hot air flow through the air duct and blows it from the air outlet to the cabinet space, so as to transfer the cold air flow or the hot air flow to the cabinet space to achieve cooling or heating.

[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 air outlet of the dual temperature cabinet is generally set toward the cabinet space, and the air outlet is connected to the air duct, which is set between the side wall and the shell of the dual temperature cabinet. The air duct and the air outlet are usually not in a straight line. In this way, when the fan causes a large amount of air to flow directly through the air duct and out of the air outlet, part of the air flow is likely to form vortices in the air duct, so that part of the air flow cannot be discharged smoothly from the air outlet, affecting the cooling or heating effect of the dual temperature cabinet.

[0044] 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.

[0045] Combination Figures 1 to 6 As shown, a dual temperature cabinet is provided according to an embodiment of the present disclosure to prevent the air flow from forming vortices inside the air duct 20.

[0046] Optionally, combined Figures 2 to 4 As shown, the dual-temperature cabinet includes a cabinet body and an air guide plate 30. The cabinet body defines a cabinet space 10 and is provided with an air duct 20. The side wall of the air duct 20 facing the cabinet space 10 is provided with a first air outlet 23, and the air duct 20 and the cabinet space 10 are connected through the first air outlet 23; the air guide plate 30 is arranged in the air duct 20; wherein, the air guide plate 30 includes a first plate surface 31, and the first plate surface 31 is provided with a first air guide 313. The first air guide 313 connects the first air outlet 23 with the air duct 20, and the air outlet direction of the first air guide 313 is toward the first air outlet 23.

[0047] Taking the warming cabinet in the cold and warm dual-temperature display cabinet with a volume range of 400-800L as an example, the warming cabinet includes a cabinet space 10, and the cabinet space 10 is provided with an air duct 20. The side wall of the air duct 20 facing the cabinet space 10 is provided with a first air outlet 23, and the air duct 20 and the cabinet space 10 are connected through the first air outlet 23. The fan 60 and the heating device 50 are arranged in the air duct 20 to blow the generated hot air flow from the first air outlet 23 to the cabinet space 10 through the air duct 20. The first air outlet 23 is arranged toward the cabinet space 10 and is connected with the air duct 20. The air duct 20 is arranged between the cabinet space 10 and the shell, and the air duct 20 and the first air outlet 23 are not in a straight line. The 400-800L warming cabinet has a larger heat load and therefore requires the fan 60 to generate more airflow. Thus, when the fan 60 blows a large amount of airflow through the air duct 20 toward the first air outlet 23, part of the airflow will form eddies in the air duct 20 and cannot be smoothly discharged from the first air outlet 23, thus affecting the heating effect of the warming cabinet.

[0048] According to the embodiment of the present disclosure, an air guide plate 30 is provided in the air duct 20, and the air guide plate 30 includes a first plate surface 31, and the first plate surface 31 is provided with a first air guide port 313, and the first air guide port 313 connects the first air outlet 23 and the air duct 20, and the air outlet direction of the first air guide port 313 is toward the first air outlet 23. In this way, the airflow in the air duct 20 can be guided by the first air guide plate 30 to blow toward the first air outlet 23, and discharged from the first air outlet 23 to the cabinet space 10, so as to avoid the formation of vortex in the air duct 20.

[0049] Optionally, the first panel surface 31 is disposed between the first air outlet 23 and a side wall of the air duct 20 facing away from the cabinet space 10 .

[0050] Optionally, along the flow direction of the airflow, the first plate surface 31 is inclined in a direction away from the first air outlet 23 .

[0051] The first plate surface 31 is disposed between the first air outlet 23 and the side wall of the air duct 20 away from the cabinet space 10, and is inclined away from the first air outlet 23 to guide the airflow to be discharged from the first air outlet 23 along the inclined direction to prevent the airflow from remaining in the air duct 20 and forming vortices.

[0052] It is understandable that the inclination direction of the first plate surface 31 is set according to the first air outlet 23 and the airflow direction. When the air duct 20 and the first air outlet 23 are in the same straight line, the first plate surface 31 may not be inclined. Along the airflow direction, the first plate surface 31 may also be set toward the first air outlet 23. When the first plate surface 31 is inclined toward the first air outlet 23, a side plate is set on the first air guide 313, and the side plate is inclined toward the first air outlet 23, so as to guide the airflow to be discharged toward the first air outlet 23.

[0053] Optionally, the air guide plate 30 also includes a second plate surface 32 , which is disposed in the air duct 20 and divides the air duct 20 into a first area 323 and a second area 324 . The first air outlet 23 is disposed corresponding to the first area 323 , and the air guide plate 30 is disposed in the first area 323 .

[0054] In the embodiment of the present disclosure, the second plate surface 32 is provided to divide the air duct 20 into a first area 323 and a second area 324, wherein the first area 323 is the air duct 20 where the hot air flows, and the second area 324 is the air duct 20 where the cold air flows. The first air outlet 23 is provided in the first area 323, and the air guide plate 30 is provided in the first area 323 to guide the hot air flow from the first air outlet 23 to the cabinet space 10, so as to realize heating of the warm cabinet.

[0055] Optionally, the second plate surface 32 is disposed in the air duct 20 and is in close contact with the air duct 20 to divide the air duct 20 into a first area 323 and a second area 324 .

[0056] Optionally, the second plate surface 32 is inclined in a direction away from the first air outlet 23 to guide the airflow to flow toward the first air outlet 23 , thereby facilitating the airflow to be discharged from the air duct 20 .

[0057] Optionally, the side wall of the air duct 20 includes a first side wall 21 and a second side wall 22, and the first air outlet 23 is arranged on the first side wall 21; the second side wall 22 is arranged opposite to the first side wall 21; the second plate surface 32 is arranged between the first side wall 21 and the second side wall 22, and the second plate surface 32 includes a first end 321 and a second end 322, the first end 321 is arranged at the first side wall 21, and the second end 322 is arranged at the second side wall 22, and along the flow direction of the airflow, the second end 322 and the first end 321 are arranged in sequence.

[0058] The first end 321 is disposed at the first side wall 21 and abuts against the first side wall 21, and the second end 322 is disposed at the second side wall 22 and abuts against the second side wall 22, so that the second plate surface 32 divides the air duct 20 into a first area 323 and a second area 324. The second plate surface 32 is inclined toward the first air outlet 23, and along the air flow direction, the air flow first passes through the second end 322 and then passes through the first end 321, so that the second plate surface 32 guides the air flow to be discharged from the first air outlet 23, thereby preventing the air flow from forming a vortex in the air duct 20.

[0059] Optionally, the first end 321 is disposed at the first air outlet 23 , and the second end 322 is connected to the first plate surface 31 and a folded angle is formed at the connection.

[0060] The second plate surface 32 is disposed in the air duct 20, the first end 321 is disposed at the first air outlet 23, the second end 322 is connected to the first plate surface 31, and a folded angle is formed at the connection to fix the second plate surface 32 in the air duct 20 and facilitate the second plate surface 32 to divide the air duct 20 into a first area 323 and a second area 324.

[0061] Optionally, the second plate surface 32 is provided with a folding plate, which is connected to the first end 321 and forms an angle at the connection. The folding plate is provided on the first side wall 21 and connected to the first side wall 21 to fix the second plate surface 32 in the air duct 20.

[0062] The first plate surface 31 and the second plate surface 32 are both disposed in the air duct 20 and are disposed at an angle to jointly guide the airflow to the first air outlet 23 to facilitate the discharge of the airflow and avoid the formation of vortices.

[0063] Optionally, combined Figure 4 and Figure 5 As shown, the air guide plate 30 also includes a first side panel 311 and a second side panel 312. The first side panel 311 is arranged at the first air guide outlet 313, one end of the first side panel 311 is connected to the first plate surface 31 and a fold is formed at the connection, and the other end of the first side panel 311 is a free end and is inclined away from the direction of the middle of the air duct 20; the second side panel 312 is arranged at the first air guide outlet 313 and is arranged opposite to the first side panel 311, one end of the second side panel 312 is connected to the first plate surface 31 and a fold is formed at the connection, and the other end of the second side panel 312 is a free end and is inclined away from the direction of the middle of the air duct 20; wherein the inclination degree of the first side panel 311 is greater than that of the second side panel 312.

[0064] One end of the first side plate 311 is connected to the first plate surface 31, and a fold is formed at the connection to fix the first side plate 311 to the first plate surface 31. The other end of the first side plate 311 is inclined in a direction away from the middle of the air duct 20, so that the first side plate 311 is inclined relative to the first plate surface 31. In this way, the airflow can be guided in a direction away from the middle of the air duct 20, so that the airflow is dispersed to both sides of the air duct 20, and the airflow is prevented from being concentrated in the middle of the air duct 20, which is difficult to discharge and forms a vortex.

[0065] The second side plate 312 is arranged opposite to the first side plate 311, and one end of the second side plate 312 is connected to the first plate surface 31, and a fold is formed at the connection to fix the second side plate 312 to the first plate surface 31. The other end of the second side plate 312 is inclined toward the middle of the air duct 20, so that the second side plate 312 is inclined relative to the first plate surface 31. In this way, the airflow can be guided toward the middle of the air duct 20, but the inclination of the first side plate 311 is greater than that of the second side plate 312, so the second side plate 312 and the first side plate 311 disperse the airflow to both sides of the air duct 20 together, so as to avoid the airflow being concentrated in the middle of the air duct 20, which is difficult to discharge and forms a vortex.

[0066] Optionally, the first side panel 311 and the second side panel 312 are arranged opposite to each other, and the width of the first side panel 311 is greater than the width of the second side panel 312, so that the inclination degree of the first side panel 311 is greater than that of the second side panel 312, so as to guide the airflow in the air duct 20 to both sides of the air duct 20, avoid a large amount of airflow hitting the middle part of the air duct 20, and also avoid the hot air flow directly hitting the first air outlet 23 and scalding the user.

[0067] Optionally, there are multiple first side panels 311 and second side panels 312, which are spaced apart in sequence along the length direction of the first panel surface 31 so that the air outlet of the first air guide port 313 is evenly distributed to both sides.

[0068] Optionally, the number of first side panels 311 and second side panels 312 is the same, the number of first air guide outlets 313 is multiple, and the multiple first air guide outlets 313 are arranged in sequence along the length direction of the first plate surface 31, and the first side panels 311 and the second side panels 312 are arranged on both sides of each first air guide outlet 313 to guide the air outlet direction of the first air guide outlet 313 to discharge air in a direction away from the middle of the air duct 20.

[0069] It can be understood that there is no specific limit to the number of the first side panel 311 and the second side panel 312. The first side panel 311 can be set only at the first air guide port 313. One end of the first side panel 311 is connected to the first plate surface 31 and a fold is formed at the connection. The other end of the first plate surface 31 is inclined in a direction away from the middle of the air duct 20. The air outlet direction at the first air guide port 313 is guided only by the first side panel 311.

[0070] Optionally, combined Figure 1 and Figure 6 As shown, the dual temperature cabinet also includes: an air outlet baffle 40, the air outlet baffle 40 includes a baffle body; the baffle body is arranged on the outside of the air duct and covers the first air outlet 23, and the baffle body is provided with a second air guide port 42, and the second air guide port 42 is connected to the first air outlet 23.

[0071] Optionally, the air outlet baffle 40 is disposed between the first air outlet 23 and the cabinet space 10 to guide the air flow from the second air guide port 42 to the cabinet space 10 .

[0072] The air outlet baffle 40 covers the first air outlet 23, and the air outlet baffle 40 is connected to the first side wall 21 to fix the air outlet baffle 40 outside the first air outlet 23. The baffle body is provided with a second air guide 42, and the second air guide 42 is connected to the first air outlet 23, so that the airflow flows out from the air duct 20, and is guided by the first air guide 313, flows to the first air outlet 23, and then flows to the cabinet space 10 through the second air guide 42.

[0073] In addition, the cabinet space 10 usually stores various foods or other items of different sizes. By providing the air outlet baffle 40, various items are prevented from entering the air duct 20 from the first air outlet 23 to block the air flow.

[0074] Optionally, the air outlet baffle 40 also includes a third side panel 41, one end of the third side panel 41 is connected to the baffle body and a fold is formed at the connection, and the other end of the third side panel 41 is a free end and is inclined in a direction away from the middle of the cabinet to limit the air outlet direction of the second air guide port 42 to be inclined in a direction away from the middle of the cabinet space 10.

[0075] There are multiple third side panels 41, and the multiple third side panels 41 are arranged at intervals along the length direction of the baffle body. At least part of the third side panels 41 are arranged on one side of the baffle body and tilted toward the left side of the cabinet space 10; at least part of the third side panels 41 are arranged on the other side of the baffle body and tilted toward the right side of the cabinet space 10. In this way, the airflow can be guided to the left and right sides of the cabinet space 10.

[0076] For example, the warming cabinet of the cold and warm dual-temperature display cabinet with a volume range of 400-800L has a large heat load, so the temperature of the hot air flow is relatively high. By obliquely setting the third side plate 41 on the baffle body, the hot air flow is guided to blow to both sides of the cabinet space 10, avoiding the hot air flow directly toward the middle of the cabinet space 10, thereby effectively preventing the hot air flow from scalding the user standing in front of the warming cabinet.

[0077] Optionally, combined Figure 3 As shown, the dual temperature cabinet further includes a heating device 50 and a cover plate 80. The heating device 50 is disposed in the air duct 20; the cover plate 80 is disposed between the heating device 50 and the side wall of the air duct 20 facing the cabinet space 10. The side wall of the air duct 20 facing the cabinet space 10 is the first side wall 21 in the above embodiment.

[0078] A heating device 50 is provided in the air duct 20 to generate a hot air flow, so that the hot air flow blows from the first air outlet 23 along the air duct 20 to the cabinet space 10 to achieve heating. When the hot air flow flows through the air duct 20, due to heat conduction, part of the heat will be transferred to the first side wall 21, and the first side wall 21 is provided between the cabinet space 10 and the air duct 20, which will increase the temperature of the first side wall 21. The first side wall 21 is in direct contact with the items in the cabinet space 10. The higher temperature of the first side wall 21 can easily cause some food to deteriorate. A cover plate 80 is provided between the heating device 50 and the cabinet space 10 to prevent heat from being directly transferred to the first side wall 21, thereby reducing food deterioration and preventing users from being scalded by contact with the first side wall 21 when taking and placing items.

[0079] Optionally, the dual temperature cabinet further includes a volute 70 and a fan 60 , wherein the volute 70 is disposed in the air duct 20 , and the fan 60 is disposed in the volute 70 for driving the air flow in the air duct 20 ; wherein the heating device 50 is disposed in the volute 70 .

[0080] Optionally, the volute 70 is provided with a second air outlet 71, the fan 60 is arranged in the volute 70, and the heating device 50 is arranged below the fan 60. After the airflow generated by the fan 60 exchanges heat with the heating device 50, the hot air flows through the second air outlet 71 and blows toward the air duct 20, and blows along the air duct 20 from the second air guide port 42 toward the cabinet space 10 to achieve heating.

[0081] Optionally, the fan 60 is a centrifugal fan, and the heating device 50 is a positive temperature coefficient heater (PTC). The PTC heater has the advantages of low thermal resistance and high heat exchange efficiency.
