Description

Technical Field

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

[0002] With the development of the catering industry and the continuous improvement of food safety standards, the daily cleaning and high-level disinfection of kitchen knives have become an indispensable part of kitchen hygiene management. Currently, commercial kitchen knife disinfection equipment on the market mainly uses hot water bath immersion, high-temperature steam fumigation, or a combination of both for sterilization.

[0003] Existing knife sterilization equipment mostly adopts traditional flip-top or drawer-type opening and closing structures. Traditional hinged flip-tops require a large vertical clearance when opening, and are prone to angular deviation or position jamming at the end of the closing process due to uneven force, making it impossible to ensure precise alignment of the upper and lower structures. At the same time, the opening action and the knife immersion action of existing equipment are usually independent. Operators often have to place the knife directly into the area near the high-temperature water tank with the lid open, and then manually close the lid. This operation method lacks a mechanical linkage error prevention mechanism, which can easily lead to hot water splashing or hot steam overflow, posing a serious risk of burns.

[0004] Secondly, for the synchronous lifting and bearing of multiple batches of cutting tools, the internal tool holder structure of existing equipment is usually quite simple, lacking strict vertical rigid guidance and limiting constraints. When placing batches or lifting the tool holder, due to the uneven distribution of the tool's center of gravity or the influence of buoyancy and resistance in the water, the tools are very prone to tilting, tipping over, or even colliding with each other on the bearing frame. This not only easily causes physical damage to the cutting edges, but also causes the lifting mechanism to jam, seriously affecting the stability of multi-batch processing operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a kitchen knife sterilization device. It solves the problem that existing knife sterilization equipment is prone to burns due to the lack of linkage protection in the opening and closing mechanism, which easily leads to high temperature overflow. In addition, the internal lifting structure lacks rigid constraints, which makes it easy for multiple batches of knives to tip over, collide, and become mechanically stuck during processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a kitchen knife sterilization device, comprising: The bottom pool and top cover are used to fix the knife-bearing structure, hot-soaking structure and hot-steaming structure of the kitchen knife disinfection device; Parallel rockers are located on the bottom pool and the top cover to form a manually towable traction structure; Parallel linkage rods are located on the bottom pool and the top cover, and work with parallel rocker arms to form a parallel unfolding traction structure for the bottom pool and the top cover; The material feeding and batching mechanism is located in the bottom pool, and works with the bottom rotating shaft of the parallel linkage rod to form a parallel distributed tool disinfection and support structure; The steam washing output mechanism is located in the bottom tank and works with the knife slot to form a synchronously split hot steam output structure. The end-pressing mechanism is located in the bottom pool and works with the convex rod structure of the parallel rocker arm, the tool placement groove, the material distribution groove, and the wedge groove to form a tool end mating and pressing structure and a cleaning structure.

[0007] Preferably, the top cover is suspended above the bottom tank, and a through-drying element is provided on the front top of the bottom tank. The parallel rocker arm is hinged to both the bottom tank and the top cover, and the protruding rod structure of the parallel rocker arm is provided on the side of the parallel rocker arm and inclined towards the top cover. The parallel linkage rod is also hinged to both the bottom tank and the top cover and is parallel to the parallel rocker arm. The material feeding and batching mechanism is installed inside the bottom tank, while the steam washing output mechanism is installed inside the top cover. The end pressing mechanism is located inside the front of the top cover and is positioned above the handle of the cutter after it is placed.

[0008] Preferably, the material feeding and batching mechanism includes a single-row bearing assembly, a traction coupling shaft, and a synchronous lifting assembly. The single-row bearing assemblies are arranged in parallel at equal intervals in the bottom pool and are connected by the traction coupling shaft, while the synchronous lifting assembly is located at both ends of the traction coupling shaft.

[0009] Preferably, the steam washing output mechanism includes a steam generating pipe, which is fixed inside the top cover, and the material distribution channels are evenly distributed at the bottom of the steam generating pipe, while the wedge-shaped slots are oppositely arranged at the bottom of the material distribution channels.

[0010] Preferably, the end pressing mechanism includes an output pressing platform, which slides along the front side of the top cover and can contact the protruding rod structure of the parallel rocker arm. The bottom of the output pressing platform is fixed with equidistant traction push-pull rods, and the bottom end of the traction push-pull rods is correspondingly fixed with clamping wedges. The clamping wedges slide and engage with the wedges in the wedge grooves at the bottom of the material distribution channel to form a relative clamping and conveying structure at the bottom of the material distribution channel.

[0011] Preferably, the single-row bearing assembly includes a blade placement channel and a blade handle channel. The blade placement channels are equidistantly distributed and fixed inside the bottom basin to form a bearing area for the blade part. The blade handle channel is fixed to the front side of the blade placement channel and forms a bearing area for the blade handle part. A bearing platform is slidably embedded inside the blade handle channel, and all bearing platforms are fixed together by a traction coupling. A bearing rail is fixed to the outside of the bearing platform and embedded in the blade handle channel. The bearing rail has a retaining strip structure on both sides, and the blade handle channel has a corresponding limiting groove. The retaining strip structure of the bearing rail slides along the limiting groove, so that the bearing rail maintains vertical displacement.

[0012] Preferably, the synchronous lifting assembly includes a trapezoidal contact bar and an output cam. The trapezoidal contact bar is fixed at both ends of the traction coupling shaft and kept parallel, while the output cam is fixed at the bottom rotating shaft of the parallel linkage rod and extends into the bottom pool. The output cam is provided with a protrusion structure that can contact the output cam.

[0013] Preferably, a rubber wiping strip is provided on the inner side of the clamping block.

[0014] Preferably, the tool slot is provided with equidistantly distributed through holes.

[0015] Preferably, the bottom of the support platform is provided with a relatively inclined and unfolded support plate to support the tool handle portion of the supported tool.

[0016] This invention provides a kitchen knife sterilization device. It has the following beneficial effects: 1. This invention utilizes a double-arm parallel linkage mechanism composed of a parallel rocker arm and a parallel linkage rod. Throughout the entire stroke of opening and closing the lid, the top cover achieves absolute parallel spatial displacement relative to the bottom pool. This structure avoids the end compression or angular interference problems that may occur at the end of the lid closing in traditional hinged flip-top designs. In actual operation, the top cover always maintains a stable horizontal lifting posture, which not only reduces the net height requirement above the equipment but also ensures that the spatial coordinates of the diversion channel inside the top cover and the bottom material feeding and batching mechanism can be precisely vertically aligned at the moment of closing.

[0017] 2. This invention uses the push-pull interaction between the bottom output cam and the trapezoidal contact bar to directly convert the device's cover-closing command into the sinking action of the internal support platform. This interlocking single power reuse mechanism ensures that the tool group is only fully immersed in the high-temperature water in the bottom pool within the same time window when the top cover is completely closed and forms a sealed safety chamber. This eliminates the risk of high-temperature water splashing out and scalding operators in the open state from a physical structure perspective, and improves the safety and coordination of batch processing operations.

[0018] 3. The invention achieves a linkage lifting through a single reverse traction force, which not only smoothly removes the cutting tool from the wet processing area, but also automatically creates an unobstructed convection path for the hot airflow of the lateral drying element through the vertical height difference of its own structure, realizing the smooth transition of processing operations from wet disinfection to dry local targeted drying.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a kitchen knife sterilization device, comprising: The bottom pool 1 and the top cover 2 are used to fix the knife-bearing structure, hot-soaking structure and hot-steaming structure of the kitchen knife disinfection device. The top cover 2 is suspended above the bottom pool 1. The top cover 2 is spatially displaced relative to the bottom pool 1 under the action of external traction force. When the two approach each other and close, a sealed chamber space is generated inside to isolate the external environment. The front top of the bottom pool 1 is provided with a through-hole drying element. The drying element outputs a continuous hot airflow to the knife handle part exposed in the opposite area. The hot airflow directly dries and covers the surface of the knife handle. Please see the appendix Figure 1 - Appendix Figure 4 The parallel rocker arm 3 is located on the bottom pool 1 and the top cover 2 to form a manually draggable unfolding traction structure. The parallel rocker arm 3 is simultaneously hinged to the bottom pool 1 and the top cover 2. The protruding rod structure of the parallel rocker arm 3 is set on the side of the parallel rocker arm 3 and tilted towards the top cover 2. The protruding rod structure on the side of the parallel rocker arm 3 tilted towards the top cover 2 swings synchronously with the overall support. The protruding rod structure uses its spatial tilting posture to directly abut and press down on the terminal pressing component at the end of the closing stroke. Please see the appendix Figure 1 - Appendix Figure 4 Parallel linkage rod 4 is located on bottom pool 1 and top cover 2, and works with parallel rocker arm 3 to form a parallel unfolding traction structure for bottom pool 1 and top cover 2. Parallel linkage rod 4 is also hinged on bottom pool 1 and top cover 2 and keeps parallel to parallel rocker arm 3. Please see the appendix Figure 3 - Appendix Figure 7 The material feeding and batching mechanism 5 is located in the bottom pool 1, and works with the bottom rotating shaft of the parallel linkage rod 4 to form a parallel distributed knife disinfection bearing structure. The material feeding and batching mechanism 5 is installed inside the bottom pool 1. Please see the appendix Figure 4 - Appendix Figure 7 The material feeding and batching mechanism 5 includes a single-row bearing assembly, a traction coupling 54, and a synchronous lifting assembly. The single-row bearing assemblies are arranged in parallel at equal intervals in the bottom pool 1 and are connected by the traction coupling 54. The synchronous lifting assembly is located at both ends of the traction coupling 54. After receiving the externally input rotational torque, the synchronous lifting assembly converts it into a vertically upward lifting force or a vertically downward releasing force, and applies this force directly to the left and right ends of the traction coupling 54. After being subjected to force, the traction coupling 54 undergoes a vertical translation as a whole, and uses its own rigid structure to distribute the translational tension force equally and synchronously to all the equidistantly connected single-row bearing assemblies, thereby ensuring that all bearing assemblies inside the bottom pool 1 can maintain an absolutely consistent vertical displacement speed and stroke distance at the same time point, and maintain the parallel posture of the tools. Please see the appendix Figure 6 - Appendix Figure 7The single-row support assembly includes a blade placement channel 51 and a blade handle channel 52. The blade placement channels 51 are evenly distributed and fixed inside the bottom pool 1 to form a support area for the blade part. The blade handle channel 52 is fixed to the front side of the blade placement channel 51 and forms a support area for the blade handle part. A support platform 53 is slidably embedded inside the blade handle channel 52, and all support platforms 53 are fixed together by a traction coupling 54. A support rail 57 is fixed to the outside of the support platform 53 and is embedded in the blade handle channel 52. The support rail 57 has a retaining strip structure on both sides. The blade handle channel 52 has a corresponding limiting groove 58 inside. Furthermore, the locking structure of the bearing rail 57 slides along the limiting groove 58, so that the bearing rail 57 maintains vertical displacement. When the traction shaft 54 ​​pulls the bearing platform 53, the bearing rail 57 on the outside of the bearing platform 53 moves synchronously. The locking structures on both sides of the bearing rail 57 slide in the limiting groove 58 inside the tool handle groove 52. The limiting groove 58 applies a strict lateral rigid constraint force to the locking structure that slides into it, forcing the bearing platform 53 to slide precisely up and down along the vertical area defined by the tool placement groove 51 and the tool handle groove 52, completely locking the horizontal degree of freedom to prevent the tool from tilting or tipping over during movement. Please see the appendix Figure 6 - Appendix Figure 7 The synchronous lifting component includes a trapezoidal contact bar 55 and an output cam 56. The trapezoidal contact bar 55 is fixed at both ends of the traction shaft 54 ​​and kept parallel. The output cam 56 is fixed at the bottom rotating shaft of the parallel linkage rod 4 and extends into the bottom pool 1. The output cam 56 is provided with a protrusion structure that can contact the output cam 56. When the bottom rotating shaft of the parallel linkage rod 4 drives the output cam 56 to rotate, the protrusion structure on the output cam 56 rotates along the set eccentric trajectory. During the eccentric rotation, the protrusion structure directly abuts against and squeezes the surface of the parallel trapezoidal contact bar 55, continuously applying a normal shear force in the vertical direction. After being pressed, the trapezoidal contact bar 55 is forced to move downward in a straight line. Through the physical compression and cooperation of the surface contours of the two, the rotational driving force of the output cam 56 is completely converted into a linear thrust that pushes the external traction component down as a whole. Please see the appendix Figure 7The tool holder channel 51 is provided with equidistantly distributed through-hole structures, and the bottom of the support platform 53 is provided with a relatively inclined and unfolded support plate 59 to support the tool handle part. When the support platform 53 is displaced downward under force, the relatively inclined and unfolded support plate 59 at the bottom firmly supports the bottom end of the tool handle in a physical form of inclined surface contact, guiding the entire tool to sink synchronously. When the support plate 59 drives the tool cutting edge part to descend to the bottom area inside the tool holder channel 51, the high-temperature fluid stored outside immediately flows in a large amount from the equidistantly distributed through-hole structures on the tool holder channel 51, so that the liquid surface inside and outside the through-hole structure is quickly connected, allowing the continuously sinking tool cutting edge to be completely submerged in the inflowing high-temperature fluid for full water bath immersion and heat conduction.

[0023] Please see the appendix Figure 8 - Appendix Figure 11 The steam washing output mechanism 6 is located in the bottom tank 1 and works with the knife slot 51 to form a synchronously diverted hot steam output structure, while the steam washing output mechanism 6 is mounted inside the top cover 2. Please see the appendix Figure 8 - Appendix Figure 11 The steam washing output mechanism 6 includes a steam generating pipe 61, which is fixed inside the top cover 2. The distribution channels 62 are equidistantly distributed at the bottom of the steam generating pipe 61, while the wedge-shaped grooves 63 are oppositely arranged at the bottom of the distribution channels 62. The steam generating pipe 61 discharges the generated high-temperature and high-pressure steam downwards into the equidistantly distributed distribution channels 62 at the bottom. The distribution channels 62 physically cut and divert the collected steam fluid, so that the airflow is sprayed vertically downwards along their respective independent channels. At the same time, the wedge-shaped grooves 63 at the bottom of the distribution channels 62 use their inclined inner walls to provide an inclined motion guide surface for the external force-bearing components, so that when the external slider is subjected to vertical downward pressure, it can be forced to undergo spatial lateral displacement along the inclined boundary of the wedge-shaped grooves 63.

[0024] Please see the appendix Figure 8 - Appendix Figure 11 The end pressing mechanism 7 is located in the bottom pool 1. It works with the protruding rod structure of the parallel rocker arm 3, the knife placement groove 51, the material distribution groove 62 and the wedge groove 63 to form a tool end docking pressing and cleaning structure. The end pressing mechanism 7 is located inside the front side of the top cover 2 and is placed above the tool handle after the tool is placed. Please see the appendix Figure 8 - Appendix Figure 11The end-pressing mechanism 7 includes an output pressing platform 71, which slides along the front side of the top cover 2 and can contact the protruding rod structure of the parallel rocker arm 3. Equally spaced traction push-pull rods 72 are fixed to the bottom of the output pressing platform 71, and corresponding clamping inclined blocks 73 are fixed to the bottom ends of the traction push-pull rods 72. The clamping inclined blocks 73 slide and engage within the wedge-shaped groove 63 at the bottom end of the material distribution channel 62, forming a relative clamping and conveying structure at the bottom end of the material distribution channel 62. The external protruding rod structure directly contacts and... When the upper surface of the output pressure table 71 is pressed, the output pressure table 71 slides downward in a straight line along the top guide surface under the force. When the output pressure table 71 moves down, it pushes the bottom traction push rod 72 to push the clamping inclined block 73 downward. After being pushed, the clamping inclined block 73 slides downward in the wedge groove 63 at the bottom of the material distribution channel 62. At this time, the outer inclined surface of the clamping inclined block 73 is squeezed by the boundary of the wedge groove 63 to generate a horizontal component force, which forces the two opposing clamping inclined blocks 73 to approach and close each other in the downward trajectory. Please see the appendix Figure 8 - Appendix Figure 11 The inner side of the clamping wedge 73 is provided with a rubber wiping strip 74. When the clamping wedges 73 on both sides are guided inward and horizontally closed by the inclined surface, the rubber wiping strip 74 fixed on the inner side of the clamping wedge 73 moves towards the center and is tightly pressed against the end surface of the handle to form a flexible clamping state. When the clamping wedge 73 is subsequently forced to move upward and is separated from the side by the restricted position, the rubber wiping strip 74 slides upward against the end surface of the handle under the action of lateral pressure, and uses the surface friction resistance of the rubber material to scrape off the residue attached to the end surface of the handle.

[0025] According to the above technical solution, the equipment performs disinfection processing of multiple batches of kitchen knives. First, the operator applies an initial pushing and pulling force to the parallel rocker arm 3. This force is converted into a torque that causes the parallel rocker arm 3 to rotate around its hinge point in the bottom basin 1. The parallel rocker arm 3 undergoes angular displacement after being subjected to this force. Simultaneously, the parallel linkage rod 4, through its hinge point with the top cover 2 and the bottom basin 1, rotates synchronously and equidistantly with the parallel rocker arm 3. The synchronous rotation of the parallel rocker arm 3 and the parallel linkage rod 4 converts the angular motion into a parallel displacement vector of the top cover 2 in space, forcing the top cover 2 to move parallel to and separate from the bottom basin 1 along a vertical and offset trajectory until the top cover 2 is fully unfolded and suspended diagonally above the bottom basin 1. After the top cover 2 is unfolded, the operator... The operator feeds the kitchen knives to be processed into the feeding and sorting mechanism 5 in batches. During this action, the blades of the knives cut vertically downwards into the internal space of the knife placement channel 51, while the handles fall precisely into the area of ​​the handle channel 52. The bottom surface of the handle directly contacts and bears pressure on the support plate 59 at the bottom of the support platform 53. The relatively tilted structure of the support plate 59 physically supports and limits the posture of the face-shaped handle bottom, so that the entire knife maintains a vertically upward static bearing state within the knife placement channel 51 and the handle channel 52. Subsequently, the operator applies a reverse closing driving force to the parallel rocker arm 3, causing the parallel rocker arm 3 to rotate in the opposite direction. The parallel linkage rod 4 rotates synchronously in the opposite direction, and the top cover 2 is pulled by the parallelogram linkage mechanism. The material is drawn downwards and closes in a parallel motion towards the bottom tank 1. During this closing stroke, two independent mechanical transmission chains are activated and run synchronously. The first transmission chain occurs on the feeding and batching mechanism 5 inside the bottom tank 1. As the parallel linkage rod 4 rotates synchronously in the opposite direction, the rotating shaft at the bottom of the parallel linkage rod 4 generates a coaxial angular velocity. This rotating shaft directly transmits the rotational kinetic energy to the output cam 56 extending into the bottom tank 1, driving the output cam 56 to rotate coaxially. During the rotation, the protrusion structure on the surface of the output cam 56 moves along a predetermined eccentric trajectory and gradually interferes with and presses against the inclined surface of the trapezoidal contact strip 55. The protrusion structure applies a continuous downward normal shear force to the trapezoidal contact strip 55, which forces it to maintain a parallel state. The trapezoidal contact bar 55 undergoes a vertical downward linear displacement. The sinking of the trapezoidal contact bar 55 directly drives the traction coupling 54 connected at both ends to move downward as a whole. The sinking of the traction coupling 54 simultaneously applies a downward vertical pulling force to all connected support platforms 53, forcing the equidistantly distributed support platforms 53 to slide downward relative to each other within the tool handle groove 52. During the downward displacement of the support platforms 53, the support rails 57 on the outer side of the support platforms 53 sink synchronously. The locking strip structures on both sides of the support rails 57 perform high-precision fitting and sliding within the corresponding limiting grooves 58 inside the tool handle groove 52. The limiting grooves 58 apply strict lateral rigid constraints to the locking strip structures of the support rails 57, completely restricting the movement trajectory of the support platforms 53 to a vertical linear motion.The vertical sinking of the support platform 53 causes the bottom support plate 59 to sink synchronously. The support plate 59 carries the entire tool downward, and the cutting edge of the tool continues to descend within the tool placement channel 51. At the same time, the high-temperature water inside the bottom pool 1 flows smoothly into the internal cavity of the tool placement channel 51 through the equally spaced through holes on the tool placement channel 51 until the sinking cutting edge is completely submerged below the surface of the high-temperature water for water bath immersion. The second transmission chain occurs in the area where the top cover 2 and the terminal docking point are located. Within the same time window when the parallel rocker arm 3 is forced to close the top cover 2 by force rotation, the protruding rod structure on the side of the parallel rocker arm 3, which is inclined towards the top cover 2, undergoes an arc-shaped spatial coordinate shift along with the rotation of the entire support. This protruding rod structure... At the end of the stroke, the output pressure plate 71 of the end-pressing mechanism 7 comes into direct mechanical contact. The squeezing force of the convex rod structure forces the output pressure plate 71 to slide downwards along the front guide rail of the top cover 2. The downward movement of the output pressure plate 71 transmits the linear thrust equally to the traction push rods 72 distributed at equal intervals at its bottom. The traction push rods 72 then push downwards against the clamping inclined blocks 73 at the bottom. After being subjected to the vertical downward thrust, the outer inclined surface of the clamping inclined blocks 73 begins to make surface contact with the inner inclined surface of the wedge-shaped groove 63 at the bottom of the material distribution channel 62. The inclined boundary of the wedge-shaped groove 63 generates a horizontal component force on the downwardly moving clamping inclined blocks 73. This component force forces the two opposing clamping inclined blocks 73 to slide downwards along the wedge-shaped groove 63 while simultaneously moving horizontally. As they move laterally closer together, this combined motion causes the rubber wiping strips 74 on the inner side of the clamping blocks 73 to gradually contract and close. When the top cover 2 is completely closed and the material distribution channel 62 of the steam washing output mechanism 6 is precisely aligned vertically with the material feeding and batching mechanism 5, the closed rubber wiping strips 74 tightly clamp the ends of the cutting tools of the upper and lower sinking cutters on the supporting plate 59 from both sides, completing the flexible docking and mechanical clamping of the cutting tool ends. After both sets of transmission chains reach the end of their stroke and maintain the mechanical locking state, the steam washing output mechanism 6 begins to work. The steam generating pipe 61 inside the top cover 2 guides the generated high-pressure, high-temperature steam to the material distribution channels 62 that are evenly distributed at its bottom. The steam fluid is sprayed vertically downwards along the inner cavity of the material distribution channel 62. Since the material distribution channel 62 has now formed a vertically connected fluid channel with the knife placement channel 51, and the docking area is covered by the clamping wedge block 73 and the rubber wiping strip 74, high-temperature steam is directly and concentratedly sprayed onto the clamped knife handle end, and diffuses downwards along the gaps in the knife placement channel 51, forming a thermodynamic convergence with the high-temperature water in the bottom pool 1. After the disinfection operation cycle is completed, the operator applies external force to the parallel rocker arm 3 again to pull open the top cover 2. At this time, the entire mechanical transmission chain reverses, the parallel rocker arm 3 rotates, driving the top cover 2 to rise in parallel, and the protruding rod structure on the parallel rocker arm 3 retracts upwards and backwards, relieving the pressure on the output pressure table 71. The output pressure table 71 slides upwards to reset, driving the traction push rod 72 to pull the clamping wedge block 73 upwards.As the clamping block 73 slides upward along the wedge groove 63, it is guided by the restricted surface to unfold horizontally to both sides, causing the rubber wiping strip 74 to detach from the end of the handle. At the instant the rubber wiping strip 74 is subjected to upward friction and retracts to both sides, it undergoes relative sliding friction with the surface of the end of the tool, scraping the condensate and residue adhering to the end of the handle downward. At the same time, the parallel linkage rod 4 rotates synchronously in the opposite direction, causing its bottom rotating shaft and output cam 56 to rotate in the opposite direction. The protrusion structure on the output cam 56 rotates with the eccentric trajectory, gradually removing the downward shearing force on the trapezoidal contact strip 55, and supporting the trapezoidal contact strip 55 from below to move upward. The traction shaft 54 ​​is subjected to force and moves upward as a whole, simultaneously lifting all the bearing platforms 53. The retaining structure of the support rail 57 slides vertically upwards in the limiting groove 58 of the tool handle channel 52. The rising of the support platform 53 causes the support plate 59 to move upwards, lifting the entire tool vertically upwards. The cutting edge is slowly pulled out of the high-temperature water surface inside the bottom tank 1 and out of the deep water area of ​​the tool placement channel 51. As the support plate 59 continues to rise to the top of its stroke, the tool is completely lifted. At this point, the tool handle is lifted and directly exposed into the through-drying area at the top front of the bottom tank 1. The drying element starts, outputting hot air in the opposite direction. The hot air directly penetrates this area, covering the tool handle suspended by the support platform 53, and removing moisture from the surface of the tool handle through convection heating and evaporation.
