Description

Technical Field

[0001] This utility model relates to an inner liner and a disinfection cabinet, belonging to the technical field of kitchen appliances. Background Technology

[0002] A disinfection cabinet is an appliance that uses ultraviolet light, high temperature and ozone to disinfect and sterilize tableware and utensils, and also has functions such as drying and storage.

[0003] Currently, in existing technologies, the drying function of disinfection cabinets mostly uses a heating device at the bottom of the cabinet cavity to raise the temperature inside the cavity, thereby accelerating the evaporation of water droplets on the surface of the tableware to achieve the purpose of drying. This method has two problems due to the effect of natural convection: First, the temperature inside the cavity is uneven, with the temperature at the top of the cavity being higher than that at the bottom, resulting in inconsistent drying time for the tableware. When drying stops, the tableware at the bottom of the cavity may still be undried. Second, the drying time for the tableware is relatively long, which affects the user experience. Utility Model Content

[0004] The purpose of this invention is to provide an inner liner and a sterilizer that can improve the uniformity of temperature inside the cavity and increase drying efficiency.

[0005] This utility model is achieved through the following technical solution.

[0006] An inner liner for use in a disinfection cabinet has an opening on the front and a cavity formed inside. An inner liner back plate and an inner liner bottom plate are formed inside the cavity. An air inlet and a first air outlet are formed on the upper and lower parts of the inner liner back plate, respectively. A second air outlet is formed on the inner liner bottom plate.

[0007] The inner liner is provided with an air duct connecting the air inlet, the first air outlet and the second air outlet. A fan is provided in the air duct to guide the air in the cavity into the air duct through the air inlet and out through the first air outlet and the second air outlet. A heating mechanism is provided in the air duct to heat the air in the air duct.

[0008] As a further improvement of this utility model, a diversion plate is provided in the air duct to divide the air duct into a first branch flow channel that connects to the first air outlet and a second branch flow channel that connects to the second air outlet.

[0009] As a further improvement of this utility model, the heating mechanism includes a first heater for heating the air in the first branch channel and a second heater for heating the air in the second branch channel.

[0010] As a further improvement of this utility model, the air duct includes, in sequence along the air flow direction, a vertical air duct located behind the inner liner back plate and extending vertically, and a horizontal air duct located below the inner liner bottom plate and extending horizontally.

[0011] As a further improvement of this utility model, the fan is located at the top of the vertical air duct.

[0012] As a further improvement of this utility model, the air duct also includes a turning air duct connecting the vertical air duct and the horizontal air duct, wherein the extending direction of the turning air duct is oblique to the vertical air duct and the horizontal air duct.

[0013] As a further improvement of this utility model, the diverter plate has a guide surface for guiding air into the first branch channel, and the extension direction of the guide surface is inclined to the air outlet direction of the vertical air duct and the first air outlet.

[0014] As a further improvement of this utility model, the horizontal air duct has an acceleration section, the cross-sectional area of ​​which gradually decreases along the air flow direction, in order to increase the air outlet speed of the second air outlet.

[0015] As a further improvement of this utility model, the second air outlet is positioned on the bottom plate of the inner liner close to the front opening of the cavity.

[0016] A disinfection cabinet, including the inner liner.

[0017] The beneficial effects of this utility model are:

[0018] When the fan and heating mechanism are started, air is drawn into the air duct through the air inlet and heated, and then blown out through the first and second air outlets. This creates forced convection of hot air in the inner chamber. Compared with traditional heating methods, on the one hand, the forced convection of hot air makes the heat distribution in the inner chamber more uniform, resulting in a more uniform temperature in the cavity. This is beneficial to the overall drying effect and avoids the problem of some tableware not being dried sufficiently. On the other hand, the forced convection of hot air can quickly remove moisture from the surface of the tableware, thereby accelerating the evaporation process and improving the drying efficiency.

[0019] Because the first air outlet is located at the bottom of the inner liner back panel, the hot air blown out by the first air inlet is from back to front, while the second air outlet is located on the bottom of the inner liner, the hot air blown out by the second air outlet is from bottom to top. This difference in air outlet direction allows the hot air circulation range within the cavity to be expanded, further improving the uniformity of the cavity temperature and the efficiency of forced convection of hot air, thereby further improving the drying effect and efficiency.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0026] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0027] Implementation Case 1:

[0028] A type of inner liner used in disinfection cabinets, see reference. Figures 1-4 The inner liner has an opening on its front and an internal cavity r for accommodating tableware to be sterilized. The cavity of the inner liner contains an inner liner back plate 11 and an inner liner bottom plate 12. An air inlet j is formed on the upper part of the inner liner back plate 11, a first air outlet k1 is formed on the lower part of the inner liner back plate 11, and a second air outlet k2 is formed on the inner liner bottom plate 12. The inner liner is equipped with an air duct 2, which communicates with the air inlet j, the first air outlet k1, and the second air outlet k2. A fan 3 is installed in the air duct 2 to guide air from the cavity r into the air duct 2 through the air inlet j and out through the first and second air outlets k1 and k2. A heating mechanism is installed in the air duct 2 to heat the air within it.

[0029] In this embodiment, the inner liner allows air to be drawn into the air duct 2 through the air inlet j and heated when the fan 3 and heating mechanism are started. Then, the air is blown out through the first air outlet k1 and the second air outlet k2, thus creating forced convection of hot air in the inner liner. Compared with traditional heating methods, on the one hand, the forced convection of hot air makes the heat distribution in the inner liner more uniform, resulting in a more uniform temperature in the cavity r, which is beneficial to the overall drying effect and avoids the problem of some tableware not being dried sufficiently. On the other hand, the forced convection of hot air can quickly remove moisture from the surface of the tableware, thereby accelerating the evaporation process and improving the drying efficiency.

[0030] Furthermore, it should be noted that since the first air outlet k1 is located at the lower part of the inner liner back plate 11, the hot air blown out by the first air inlet j is from back to front, and the second air outlet k2 is located on the inner liner bottom plate 12, the hot air blown out by the second air outlet k2 is from bottom to top. This makes the air outlet directions of the first air outlet k1 and the second air outlet k2 different, which can expand the range of hot air circulation in the cavity r, further improve the temperature uniformity of the cavity r and the efficiency of forced convection of hot air, thereby further improving the drying effect and efficiency.

[0031] In this embodiment, a flow divider 4 is installed inside the air duct 2, which divides the air duct 2 into a first branch flow channel 2a and a second branch flow channel 2b. The first branch flow channel 2a is connected to the first air outlet k1, and the second branch flow channel 2b is connected to the second air outlet k2. Air in the cavity r is drawn into the air duct 2 through the air inlet j. As the air flows through the air duct 2, when it passes through the flow divider 4, part of the air flows into the first branch flow channel 2a and is blown out through the first air outlet k1, while the other part flows into the second branch flow channel 2b and is blown out through the second air outlet k2. By installing the flow divider 4 inside the air duct 2 and dividing the air into the first branch flow channel 2a and the second branch flow channel 2b, the airflow volume of the first air outlet k1 and the second air outlet k2 can be balanced, and the blowing state of the first air outlet k1 and the second air outlet k2 can be kept stable, which is beneficial to the stable circulation of hot air in the cavity r.

[0032] In this embodiment, the heating mechanism includes a first heater 51 and a second heater 52. The first heater 51 is disposed in the first branch channel 2a and heats the air in the first branch channel 2a. The second heater 52 is disposed in the second branch channel 2b and heats the air in the second branch channel 2b, making the temperature control of the hot air blown out from the first air outlet k1 and the second air outlet k2 more precise. In addition, the first air outlet k1 is closer to the air inlet j than the second air outlet k2, making the air flow path in the first branch channel 2a shorter than that in the second branch channel 2b. Therefore, compared with setting a single heater in the air duct 2 for heating, this embodiment uses the first heater 51 and the second heater 52 to heat the air in the first branch channel 2a and the second branch channel 2b separately, which can prevent the temperature of the hot air blown out from the second air outlet k2 from failing to meet the performance requirements.

[0033] In this embodiment, the air duct 2 includes, in sequence along the airflow direction, a vertical air duct 21 extending vertically behind the inner liner back plate 11 and a horizontal air duct 23 extending horizontally below the inner liner bottom plate 12. The vertical air duct 21 and the horizontal air duct 23 minimize the airflow path within the air duct 2, thereby increasing the overall hot air circulation speed and improving the drying effect. A portion of the vertical air duct 21 extending from its bottom to the distribution plate 4 belongs to the first branch air duct 2a, and the other portion belongs to the second branch air duct 2b. The horizontal air duct 23 belongs to the second branch air duct 2b.

[0034] In this embodiment, the fan 3 is located at the top of the air duct 2, that is, at the top of the vertical air duct 21, so that the position of the fan 3 in the air duct 2 is closer to the air inlet j, thus ensuring the negative pressure intensity at the air inlet j and further improving the circulation speed of the hot air in the heat exchanger.

[0035] In this embodiment, the air duct 2 also includes a turning air duct 22, which connects the vertical air duct 21 and the horizontal air duct 23. The turning air duct 22 is part of the second branch flow duct 2b. The extension direction of the turning air duct 22 is inclined to the vertical air duct 21 and the horizontal air duct 23. When the air flows from the vertical air duct 21 to the turning air duct 22, its flow direction changes once. When the air flows from the turning air duct 22 to the horizontal air duct 23, its flow direction changes a second time. The turning air duct 22 can play a transition buffer role for the air flow by changing the air flow direction twice, thereby reducing kinetic energy loss.

[0036] In this embodiment, the splitter plate 4 has a guide surface 41 that guides air into the first branch channel 2a. The extension direction of the guide surface 41 is inclined to the vertical air duct 21 and the air outlet k1. The guide surface 41 causes the air to change its flow direction when it flows from the vertical air duct 21 to the first branch channel 2a, which plays a transition buffer role for the air flow and reduces kinetic energy loss.

[0037] In this embodiment, the horizontal air duct 23 has a speed-up section 231. The cross-sectional area of ​​the speed-up section 231 gradually decreases along the air flow direction, so that the air flows in the horizontal air duct 23 and its flow speed is increased after passing through the speed-up section 231, and finally the air outlet speed of the second air outlet k2 is increased. By increasing the forced convection speed in the cavity r through local speed-up, the overall circulation efficiency of hot air is improved.

[0038] In this embodiment, the second air outlet k2 is located on the bottom plate 12 of the inner liner near the front opening of the cavity r. Since the hot air blown out by the second air outlet k2 is from bottom to top and the second air outlet k2 is close to the front opening of the cavity r, the hot air blown out by the second air outlet k2 can basically cover the space of the cavity r near the front opening, thereby further improving the temperature uniformity of the cavity r.

[0039] Implementation Case 2:

[0040] A disinfection cabinet includes an inner liner, as shown in Example 1.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features.
