Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, specifically to a disinfection cabinet. Background Technology

[0002] Most existing disinfection cabinets have two drawers, one above the other, for storing tableware.

[0003] To increase storage capacity, some disinfection cabinets have an inner drawer at the top for storing small tableware such as chopsticks and spoons. For details, please refer to the Chinese invention patent "A Disinfection Cabinet" with patent application number CN201210272461.5 (publication number CN102813946B).

[0004] However, in existing disinfection cabinets, the heating system is generally located at the bottom of the cabinet. As a result, the inner drawer at the top receives relatively little heat, which means that the small tableware inside cannot be fully dried. In addition, the disinfection lamp is usually installed on the rear wall inside the cabinet. On the one hand, the inner drawer is relatively enclosed, making it difficult for the disinfection light from the disinfection chamber to penetrate into the inner drawer, thus making it difficult to guarantee the disinfection effect of the small tableware placed inside. On the other hand, the disinfection lamp is relatively troublesome to install and remove. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a disinfection cabinet that can improve the drying effect of tableware inside the inner drawer, in light of the current state of the technology.

[0006] The second technical problem to be solved by the present invention is to provide a disinfection cabinet with convenient loading and unloading of disinfection components.

[0007] The third technical problem to be solved by the present invention is to provide a disinfection cabinet that can improve the disinfection effect of tableware inside the inner drawer.

[0008] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a disinfection cabinet, comprising...

[0009] The cabinet has a disinfection chamber inside;

[0010] An internal drawer, located at the top of the disinfection chamber, can be pulled in and out of the disinfection chamber; and

[0011] A heating element is installed on the cabinet and acts on the disinfection chamber;

[0012] The feature is that: the bottom wall inside the inner drawer has a recessed water collection groove, and a water passage hole is opened through the bottom wall of the water collection groove in the vertical direction;

[0013] The disinfection chamber also includes a turbulence component for promoting airflow disturbance. The turbulence component includes a fixed base installed at the bottom of the inner tube and an impeller rotatably connected to the fixed base. The impeller faces the water passage hole so that the impeller can rotate around its own axis under the action of water droplets dripping from the water passage hole.

[0014] In order to dynamically reflect the disinfection light while the impeller is rotating, a disinfection component is also included, which can generate disinfection light and act on the disinfection chamber. The impeller includes a rotating shaft rotatably connected to the fixed base and at least two blades arranged at intervals along the circumference of the rotating shaft. The surface of the blades is made of a material that can reflect disinfection light.

[0015] To further address the second technical problem mentioned above, the disinfection component is detachably installed at the bottom of the inner drawer.

[0016] In order to enable the detachable installation of the disinfection component on the inner drawer, the bottom wall inside the inner drawer has a downward recessed part, and a clearance opening is provided through the bottom wall inside the recessed part in the vertical direction.

[0017] The disinfection component includes:

[0018] The tray can pass through the relief opening from bottom to top and rest on the bottom wall inside the recess.

[0019] A pull rope, the top of which is attached to the tray;

[0020] A tube cover, having an opening at the bottom, is connected to the bottom end of the pull rope; and

[0021] The disinfection lamp tube is installed inside the aforementioned tube cover;

[0022] In order to achieve dynamic disinfection, the disinfection lamp can remain stationary relative to the cabinet without airflow disturbance, and can move relative to the cabinet with the tube cover under the action of the hot airflow generated by the heating element.

[0023] To enhance the interaction between the movement of the disinfection lamp tube and the rotation of the baffle, the fixing base is fixed relative to the tube cover, and the rotating shaft extends along the length of the disinfection lamp tube.

[0024] To ensure that the disinfection lamp tube is subjected to balanced forces, the number of the turbulence-disrupting components is one pair, and they are symmetrically arranged on both sides of the tube cover.

[0025] In order to effectively reflect disinfection light and improve disinfection efficiency, the inner wall of the tube cover is made of a material that can reflect disinfection light.

[0026] In order to focus the disinfection light and improve the disinfection intensity, the tube cover is in the shape of a trumpet with the diameter gradually increasing from top to bottom.

[0027] To further address the third technical issue mentioned above, the sidewall of the tube cover is made of a transparent material that allows the disinfection light to pass through, and / or has multiple flow holes for fluid passage. In this way, the disinfection light generated by the disinfection lamp can sequentially pass through the flow holes and water holes to illuminate the tableware inside the inner drawer.

[0028] To prevent water droplets from the water inlet from passing through the flow hole and affecting the operation of the disinfection lamp, the orthogonal projections of the flow hole and the water inlet on the horizontal plane do not overlap.

[0029] To facilitate the quick insertion of the tray, which passes through the clearance opening from bottom to top, into the recess, the diameter of the recess gradually decreases from top to bottom, at least in certain areas.

[0030] To facilitate the user's pulling out of the inner drawer, the front of the inner drawer has a handle groove with a bottom opening for inserting fingers.

[0031] To facilitate the formation of the handle groove, the top edge of the front side of the inner drawer extends forward and then downward to form a bent portion, which surrounds the front end face of the inner drawer to form the handle groove.

[0032] Compared with the prior art, the advantages of the present invention are as follows:

[0033] (1) By using a fixed base installed at the bottom of the inner drawer and an impeller rotatably connected to the fixed base to form a turbulence component for promoting airflow disturbance, the impeller is positioned directly opposite the water hole on the bottom wall of the inner drawer so that the impeller can rotate around its own axis under the action of the water droplets dripping from the water hole, thereby strengthening the airflow disturbance and making the temperature field in the sterilization chamber more uniform, which is beneficial to improving the overall tableware drying effect in the inner drawer and sterilization chamber.

[0034] (2) By detachably installing the disinfection component at the bottom of the inner drawer, when the disinfection component needs to be installed, repaired or replaced, the inner drawer can be pulled out to install or remove the disinfection component, which is convenient and efficient.

[0035] (3) By designing the perimeter wall of the tube cover to be made of a transparent material that allows the disinfection light to pass through or / and opening multiple flow holes for fluid to pass through, the disinfection light generated by the disinfection lamp tube can sequentially pass through the flow holes and water holes to irradiate the tableware inside the inner drawer, thereby improving the disinfection effect of the tableware inside the inner drawer.

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0043] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0044] like Figures 1 to 6 The diagram shows a preferred embodiment of the disinfection cabinet of the present invention. The disinfection cabinet includes a cabinet body 1, a drawer 2, an inner drawer 3, a heating element 5, a disinfection component 6, and a turbulence component 7.

[0045] The cabinet 1 has a disinfection chamber 11 inside and an opening on the front.

[0046] There are two drawers 2. The drawer 2 located at the top is called the upper drawer, and the drawer 2 located at the bottom is called the lower drawer. Each drawer 2 can be pulled in and out of the disinfection chamber 11 through the opening on the front side of the cabinet 1.

[0047] The inner drawer 3 is located at the top of the disinfection chamber 11 and can be pulled in and out of the disinfection chamber 11 through the opening on the front side of the cabinet 1. When the upper drawer is closed, the inner drawer 3 is housed at the top of the inner cavity of the upper drawer.

[0048] Specifically, the top edge of the front side of the inner drawer 3 extends forward and then downward to form a bent portion 31. The bent portion 31 and the front end face of the inner drawer 3 surround a handle groove 311 with a bottom opening for inserting fingers to facilitate the user to pull out the inner drawer 3. The inner drawer 3 has a recessed portion 34 at the center of the inner bottom wall. The bottom wall of the recessed portion 34 has a vertically penetrating opening 341, and the diameter of the recessed portion 34 gradually decreases from top to bottom. The inner bottom wall of the inner drawer 3 has four recessed water collection grooves 35 arranged circumferentially along the recessed portion 34. The bottom wall of the water collection grooves 35 has multiple water passages 351 penetrating from top to bottom.

[0049] Heating element 5 is a serpentine heating tube, which is embedded in the bottom wall of cabinet 1.

[0050] The disinfection component 6 is detachably installed at the bottom of the inner drawer 3 and includes a tray 61, a pull cord 62, a tube cover 63, and a disinfection lamp tube 64.

[0051] Specifically, the tray 61 can pass through the above-mentioned relief opening 341 from bottom to top and rest on the bottom wall inside the above-mentioned recess 34, thereby facilitating the loading and unloading of the tray 61 in the recess 34.

[0052] The top of the pull rope 62 is connected to the support plate 61;

[0053] The tube cover 63 is connected to the bottom end of the pull rope 62. The tube cover 63 is a trumpet shape with a diameter that gradually increases from top to bottom. It has an opening at the bottom. The inner wall of the tube cover 63 is made of a material that can reflect disinfection light. Multiple flow holes 631 for fluid to pass through are opened on the left and right side walls of the tube cover 63. The flow holes 631 do not overlap with the orthographic projection of the water passage hole 351 on the horizontal plane, thereby preventing water droplets dripping from the water passage hole 351 from passing through the flow holes 631 and affecting the operation of the disinfection lamp tube 64.

[0054] The disinfection lamp tube 64 is an ultraviolet lamp tube, which is installed inside the tube cover 63. The ultraviolet light it produces can directly irradiate the tableware in the disinfection chamber 11 and irradiate the tableware in the inner drawer 3 in sequence through the flow hole 631 and the water hole 351.

[0055] In this way, under the condition of no airflow disturbance, the disinfection lamp tube 64 can be arranged horizontally and remain stationary relative to the cabinet 1 in a static equilibrium state; under the action of the hot airflow generated by the heating element 5, the static equilibrium is broken, and the disinfection lamp tube 64 can move relative to the cabinet 1 with the tube cover 63.

[0056] There are a pair of turbulence-disrupting components 7, symmetrically arranged on both sides of the tube cover 63. Each turbulence-disrupting component 7 includes a mounting base 71 and an impeller 72.

[0057] Specifically, the fixing base 71 includes two mounting plates 711 respectively connected to the front and rear parts of the outer side wall of the tube cover 63, and a mounting rod 712 connected between the two mounting plates 711.

[0058] The impeller 72 includes a shaft 721 and four blades 722 arranged circumferentially along the shaft 721. The shaft 721 extends along the length of the disinfection lamp tube 64, is rotatably mounted on the mounting rod 712, and is located between two mounting plates 711. The blades 722 are made of a material that reflects disinfection light, with their long sides extending along the length of the disinfection lamp tube 64 and their short sides extending radially along the shaft 721. In this embodiment, the blades 722 of the impeller 72 face the water passage 351, so that the impeller 72 can rotate around the mounting rod 712 under the action of water droplets dripping from the water passage 351, thereby promoting airflow turbulence.

[0059] The working principle of this embodiment is as follows:

[0060] (1) During operation, the disinfection light generated by the disinfection lamp tube 64 directly irradiates the tableware in the disinfection chamber 11 on the one hand, and on the other hand, it irradiates the tableware in the inner drawer 3 through the flow hole 631 and the water hole 351 in sequence. At the same time, the heat generated by the heating element 5 is released to the disinfection chamber 11 to dry the tableware in the disinfection chamber 11 and the inner drawer 3.

[0061] During this process, after cleaning the residual moisture on the surface of the small tableware placed in the inner drawer 3, the moisture gathers in the water collection tank 35 and drips into the disinfection chamber 11 through the water passage 351, acting on the blades 722 of the impeller 72, thereby driving the impeller 72 to rotate around the mounting rod 712. This mainly serves three purposes: First, it strengthens the airflow disturbance, making the temperature field in the disinfection chamber 11 more uniform, which is beneficial to improving the overall tableware drying effect in the inner drawer 3 and the disinfection chamber 11; Second, under the irregular impact of the airflow generated by the rotation of the impeller 72, the disinfection lamp tube 64 swings or even rotates relative to the cabinet 1 with the tube cover 63, breaking the static balance and forming dynamic disinfection light for dynamic disinfection; Third, the rotating blades 722 can dynamically reflect the disinfection light.

[0062] In addition to the effects of water droplets, the disturbance of the hot airflow, the rotation of the impeller 72, and the oscillation and rotation of the tube cover 63 complement each other. When the static balance is broken by the hot airflow at any point, it not only creates movement at that point but also indirectly promotes the breaking of other static balances. This provides a continuous source of power for maintaining the spontaneous movement of the entire device during the disinfection and drying process until the disinfection and drying are completed, the water droplets stop dripping, the hot airflow stops, and the internal temperature field becomes uniform, at which point the device returns to a state of static balance.

[0063] (2) When it is necessary to install, repair or replace the disinfection lamp tube 64, first open the upper drawer and inner drawer 3, then lift the tray 61 along with the pull rope 62, and finally move the tray 61 down along the width direction of the clearance opening 341 to remove the disinfection component 6 for repair or replacement. The operation is convenient and efficient.
