[0006] The main body is rotatably provided with a compartment door, which is used to close the opening.

[0007] The top of the storage compartment is equipped with an ultraviolet lamp;

[0008] The door includes an inner side, on which a window and a reflective protrusion are provided; wherein, the inner side is positioned directly opposite the storage compartment when the door is closed;

[0013] In the reflective protrusion, two adjacent sides are connected by an arc surface.

[0014] In one possible implementation, the inner side is provided with a first placement area and a second placement area, the first placement area being surrounded by the second placement area; wherein, the window is disposed in the first placement area, and the reflective protrusion is disposed in the second placement area;

[0015] The reflective protrusions are evenly distributed within the second placement area; wherein, within the second placement area, the distance between two adjacent reflective protrusions is 6 to 12 mm.

[0016] In one possible implementation, the window includes one-way glass for reflecting light emitted by the ultraviolet lamp.

[0043] Example

[0044] See Figure 1 , Figure 2 and Figure 3 In this embodiment, a knife holder with better disinfection effect based on light reflection is proposed. The knife holder includes a main body 100, and a storage compartment 110 is provided inside the main body 100. An opening 111 is provided on the side of the storage compartment 110, wherein the opening 111 is connected to the storage compartment 110.

[0045] A door 200 is rotatably provided on the main body 100, and the door 200 is used to close the opening 111.

[0046] like Figure 3 and Figure 8 As shown, an ultraviolet lamp 310 is installed on the top of the storage compartment 110.

[0047] The door 200 includes an inner side 210, on which a window 320 and a reflective protrusion 400 are provided. The inner side 210 is positioned directly opposite the storage compartment 110 when the door 200 is closed.

[0048] An observation window 201 is provided on the outer surface of the storage door 200, and the observation window 201 is positioned opposite to the window 320. The user can observe the interior of the storage compartment 110 through the observation window 201 and the window 320.

[0049] The reflective protrusion 400 is used to reflect the light emitted by the ultraviolet lamp 310. When the door 200 is closed, at least a portion of the surface of the reflective protrusion 400 faces the storage compartment 110.

[0050] After the door 200 is closed, the opening 111 of the storage compartment 110 is sealed. Then, the ultraviolet lamp 310 is activated, allowing the ultraviolet light emitted by the lamp to illuminate the interior of the storage compartment 110. Furthermore, since at least a portion of the surface of the reflective protrusion 400 faces the storage compartment 110 when the door 200 is closed, the reflective protrusion 400 can reflect a portion of the light emitted by the ultraviolet lamp 310 back into the storage compartment 110. Therefore, through the combined effects of the ultraviolet lamp 310 and the reflective protrusion 400, disinfection within the storage compartment 110 becomes more comprehensive and thorough, effectively reducing blind spots in ultraviolet radiation and significantly improving the sterilization efficiency of the items inside, resulting in a better disinfection effect.

[0051] Both storage compartment 110 and compartment door 200 can be made of stainless steel.

[0052] In this embodiment, the roughness of the inner surface 210 and the inner wall of the storage compartment 110 is 0.4 to 0.8 μm, and the reflection coefficient of the inner surface 210 and the inner wall of the storage compartment 110 is 65% to 85%.

[0053] The inner surface 210 and the inner wall of the storage chamber 110 have the same roughness, which can ensure that their scattering characteristics are consistent, thus forming a uniform scattering environment, achieving uniform scattering of ultraviolet rays irradiating themselves, so that ultraviolet rays can be more evenly distributed throughout the storage chamber 110.

[0054] Tests showed that if the roughness value is too low, it will cause specular reflection, which will cause light to be reflected at a fixed angle, forming strong bright spots and deep shadow areas, resulting in the ultraviolet light not being evenly distributed throughout the storage chamber 110; if the roughness value is too high, too much ultraviolet light will be absorbed, the scattering efficiency will decrease, and the rough surface will be more likely to hide microorganisms and dirt, which is not conducive to cleaning and disinfection.

[0055] The uniform distribution of ultraviolet light within storage chamber 110 relies on multiple reflections of the light, with each reflection resulting in energy loss (such as light absorption by materials). If the reflectivity is too low, the light intensity will decrease to an ineffective level after only a few reflections, failing to reach hidden corners within the chamber and leading to disinfection failure. A reflectivity range of 65% to 85% ensures that the ultraviolet light maintains effective intensity after undergoing a sufficient number of reflections (e.g., more than 10 times) within the chamber.

[0056] If a reflectivity of over 85% is required, complex surface treatments are needed for the inner surface 210 and the inner wall of the storage compartment 110. This will increase manufacturing costs and reduce the roughness of the inner surface 210 and the inner wall of the storage compartment 110 (making the surface smoother). As a result, the diffuse reflection of light by the inner surface 210 and the inner wall of the storage compartment 110 will be weaker, while the total internal reflection will be stronger. This will result in a strong but uneven light field, i.e., bright light spots and deep shadow areas, forming inside the storage compartment 110, causing ultraviolet light to fill the entire storage compartment 110.

[0057] In this embodiment, the ultraviolet light emitted by the ultraviolet lamp 310 undergoes a cycle of "irradiating one surface - diffuse reflection - irradiating another surface" between the inner side 210 and the inner wall of the storage compartment 110. Although there is some energy loss with each reflection, the direction of the light is continuously randomized. Ultimately, a diffuse reflection light field with extremely uniform distribution, although its intensity is somewhat attenuated, is formed inside the storage compartment 110, achieving irradiation without blind spots.

[0058] like Figure 4 As shown, the reflective protrusion 400 is truncated pyramidal in shape. The bottom surface of the reflective protrusion 400 is coplanar with the inner surface 210, and the top surface of the reflective protrusion 400 is parallel to the inner surface 210. When the door 200 is closed, the top surface of the reflective protrusion 400 and the inner surface 210 are directly opposite the storage compartment 110, and the side surface of the reflective protrusion 400 faces the storage compartment 110 at a certain angle. The part indicated by arrow A in the figure is the top surface of the reflective protrusion 400.

[0059] The height of the reflective protrusion 400 is 5–10 mm. The bottom surface of the reflective protrusion 400 is rectangular with a side length of 10–20 mm. The top surface of the reflective protrusion 400 is rectangular with a side length of 4–8 mm. Rectangles include squares. The attached diagram is for illustrative purposes only and does not represent actual dimensions.

[0060] If the size of the reflective protrusion 400 is too large, it will cause shadow areas to appear between the reflective protrusions 400; if the size of the reflective protrusion 400 is too small, the reflection and scattering effects will be insufficient, and it will be impossible to obtain reflected light rays with random paths to fully fill the storage compartment 110.

[0061] On the same reflective protrusion 400, two adjacent sides are connected by an arc surface 401. This effectively increases the surface area of ​​the reflective protrusion 400 while ensuring that the volume of the reflective protrusion 400 is constant, thereby increasing the reflective area of ​​the reflective protrusion 400 for ultraviolet light.

[0062] like Figure 2 As shown, the inner side 210 is provided with a first resettlement area 211 and a second resettlement area 212, with the first resettlement area 211 surrounded by the second resettlement area 212. A window 320 is provided in the first resettlement area 211, and a reflective protrusion 400 is provided in the second resettlement area 212.

[0063] The reflective protrusions 400 are evenly distributed within the second placement area 212. Within the second placement area 212, the distance between two adjacent reflective protrusions 400 is 6–12 mm. This distribution pattern creates a high-density reflective array, allowing light reflected by the reflective protrusions 400 to more evenly illuminate the storage compartment 110.

[0064] Window 320 includes one-way glass, which reflects light emitted by the ultraviolet lamp. Due to the presence of the one-way glass, ultraviolet light inside the chamber cannot escape through observation window 201.

[0065] like Figure 5 As shown, window 320 includes a first reflective surface 321 and a second reflective surface 322.

[0066] The first reflective surface 321 is parallel to the inner surface 210. The second reflective surface 322 is arranged circumferentially along the first reflective surface 321, and the second reflective surface 322 is located between the first reflective surface 321 and the inner surface 210.

[0067] The distance between the first reflective surface 321 and the inner surface 210 is greater than the height of the reflective protrusion 400.

[0068] When the door 200 is closed, the first reflective surface 321 faces the storage compartment 110. In this way, the ultraviolet light reflected from the first reflective surface 321 will shine directly into the storage compartment 110. The bottom surface of the storage compartment 110 facing the first reflective surface 321 will reflect the light emitted from the first reflective surface 321, so that the light can shine into the inner side 210. This cycle continues, so that the light can fill the compartment.

[0069] The light reflected by the second reflective surface 322 will shine on the reflective protrusion 400 of the second placement area 212, so that the side of the reflective protrusion 400 can reflect the light emitted from the window 320 again, thereby reflecting higher energy reflected light into the storage compartment 110.

[0070] like Figure 2 As shown, a sealing gasket 213 is provided circumferentially on the inner side 210. The sealing gasket 213 is used to seal against the edge of the opening 111 when the door 200 is closed. The sealing gasket 213 can seal the opening 111 and prevent ultraviolet light from leaking into the compartment.

[0071] like Figure 3 As shown, there are two ultraviolet lamps 310, which are spaced apart along the width of the storage compartment 110. The distance between the two ultraviolet lamps 310 is h, and the width of the storage compartment 110 is H, where 0.5H ≤ h < H. This arrangement allows the light emitted by the two ultraviolet lamps 310 to evenly illuminate the storage compartment 110, making the light field more uniform at all locations within the compartment.

[0075]

[0076] Referring to Table 1, the sterilization rate of this solution reaches over 99%, which can well meet the hygiene requirements of the knife holder.

[0077] like Figure 6 As shown, a detachable storage basket 112 is provided inside the storage compartment 110, which is used to store tableware. The tableware includes chopsticks, spoons, forks, or small fruit knives, peelers, etc.

[0078] like Figure 7 As shown, the main body 100 has a knife-holding cavity 120 and a partition 101 inside, and the knife-holding cavity 120 is used to hold the knife. The knife-holding cavity 120 and the storage compartment 110 are located on opposite sides of the partition 101.

[0079] like Figure 6 As shown, a cover plate 121 is provided on the top of the tool holder 120, and a tool insertion groove 122 is provided on the cover plate 121, wherein the tool insertion groove 122 is used for the tool body to pass through.

[0080] like Figure 1 As shown, a suction cup 130 is provided at the bottom of the main body 100. The suction cup 130 can adhere to the kitchen countertop, thereby improving the stability of the knife holder.

[0081] like Figure 3 and Figure 8 As shown, the top of the storage compartment 110 is also equipped with an LED bead 330, which is used to emit purple or blue light.
