Description

Technical Field

[0001] The invention relates to the field of household appliances, and in particular to a tableware disinfection cabinet. Background Art

[0002] The existing tableware disinfection cabinet generally includes two layers of drawers, one above the other, and both the upper and lower drawers can be used to place the tableware to be disinfected. In the existing disinfection cabinet, the upper and lower drawers are generally arranged in a through chamber, and the tableware on the two layers is processed simultaneously during disinfection and drying. The current tableware disinfection cabinet generally does not have a water receiving device, and water droplets will remain on the surface of the cleaned tableware. When the drawer is pulled out to place the cleaned tableware, the water droplets on the tableware will drip onto the ground through the drawer basket, and after the drawer after placing the tableware is pushed back to the disinfection liner, the water droplets on the tableware will drip onto the inner bottom surface of the disinfection liner, which will cause stains on the inner bottom surface of the disinfection liner after long-term use, and the stains are difficult to clean after repeated rewetting and drying. At the same time, the water droplets on the tableware in the upper drawer will drip onto the lower drawer, which not only increases the time required for drying the tableware on the lower drawer, but also if the upper tableware is not cleaned or the upper tableware is contaminated, the water droplets on the upper tableware will drip onto the lower tableware, causing contamination of the lower tableware.

[0003] In the existing disinfection cabinet, the heating tube is generally arranged at the bottom of the disinfection inner tank, and its top surface is in direct contact with the bottom surface of the disinfection inner tank. In this way, the heating tube transfers heat to the inner tank by heat radiation, thereby achieving the purpose of high-temperature sterilization and rapid decomposition of ozone. At the same time, the hot air is used to dry the surface and inner tank of the tableware, so that the tableware is in a dry environment, and the dry environment can effectively prevent bacterial growth. However, since the lower drawer is closer to the heating tube, the temperature field of the upper and lower drawers is uneven, thereby affecting the disinfection effect and drying effect. If a water receiving box is set under each layer of drawers, although the water droplets on the surface of the tableware can be collected by the water receiving box, it will aggravate the poor air flow of the upper and lower drawers, further affecting the disinfection effect and drying effect of the upper drawer. In addition, since there are residual water droplets on the surface of the tableware after washing, the water droplets are heated into water vapor, causing the moisture in the disinfection inner tank to soar, thereby affecting the drying speed and disinfection effect of the tableware. In addition, when there are fewer disinfected tableware, heating the upper and lower drawers at the same time will cause energy waste and also affect the disinfection efficiency. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a tableware disinfection cabinet capable of promoting internal airflow in view of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a tableware disinfection cabinet which can simultaneously disinfect the lower drawer separately and the upper and lower drawers at the same time in view of the prior art.

[0006] The third technical problem to be solved by the present invention is to provide a tableware disinfection cabinet capable of collecting water droplets on the surface of tableware in view of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a tableware disinfection cabinet, comprising a disinfection inner tank with a front opening, a heating device is arranged at the bottom of the disinfection inner tank, an upper drawer and a lower drawer are arranged in the disinfection inner tank, and the bottom of the upper and lower drawers are respectively provided with a guide layer, and the guide layer has

[0008] A first guide arc surface, which is located on the bottom surface of the guide layer and protrudes downward, and the first guide arc surfaces are at least two arranged in parallel;

[0009] A guide gap is located between two adjacent first guide arc surfaces;

[0010] The flow guide control member is arranged above the flow guide gap, and the flow guide control member can be driven by the driving structure to open the flow guide gap or be closed by the flow guide control member.

[0011] Preferably, the flow control member is an impeller structure, and the outer surfaces of each adjacent blade of the flow control member respectively constitute a smooth second flow guide arc surface. The above-mentioned flow guide layer also has an upwardly open water collecting groove, the number of which corresponds one-to-one to the above-mentioned first flow guide arc surface, and each water collecting groove is located on the upper part of the corresponding first flow guide arc surface. The above-mentioned flow control member has at least two states during operation: the first is that the outer edges of two blades of the flow control member along the axial direction of the flow control member are respectively against the corresponding top edges of the water collecting grooves on both sides, and the above-mentioned flow guide gap is closed; the second is that the blades of the flow control member are separated from the water collecting grooves on both sides, and at least two of the blades are located in the water collecting grooves at the vertical projections of the water collecting grooves on both sides. In the first state, the flow guide gap is closed by the flow guide control member, so that the upper and lower drawers can be separated from each other by the flow guide layer at the bottom of the upper drawer. In the second state, water droplets on the tableware in each drawer can drip onto the second flow guide arc surface of the flow guide control member. As the flow guide control member rotates, the water droplets dripping onto the second flow guide arc surface are dripped into the water collection tank, so that the water droplets on the tableware in the upper drawer can be prevented from dripping onto the lower drawer and the water droplets on the upper and lower drawers can be prevented from dripping onto the inner surface of the disinfection liner, thereby improving the user experience. Of course, the water droplets on the tableware can also drip directly into the water collection tank.

[0012] Preferably, a sealing strip is provided on the top edge of each water collecting trough along its length direction, so that each flow guiding control member can better seal the corresponding flow guiding gap in the second state.

[0013] Preferably, an ultraviolet lamp is provided in the disinfection inner container, and the exposed surfaces of the above-mentioned guide layer are all reflective surfaces. In this way, the ultraviolet light irradiated on the guide layer can be reflected and focused by the reflective surface on the outer surface of the guide layer, thereby increasing the irradiation range of the ultraviolet light and enhancing its irradiation intensity, thereby enhancing the disinfection effect of the ultraviolet light.

[0014] The above-mentioned guide layer can be implemented in a variety of specific ways. Preferably, each of the guide layers includes a water collecting cover, and each water collecting cover extends along the left-right or front-back direction of the corresponding drawer. At the same time, the water collecting covers in each guide layer are evenly spaced along the front-back or left-right direction of the corresponding drawer. Correspondingly, each of the above-mentioned guide control parts also extends along the left-right or front-back direction of the drawer, and the guide control parts of each guide layer are also evenly spaced along the front-back or left-right direction of the corresponding drawer. The cross-section of each water collecting cover is arc-shaped and closed at both ends. The inner cavity of each water collecting cover constitutes the above-mentioned water collecting trough, and the bottom surface of each water collecting cover constitutes the above-mentioned first guide arc surface.

[0015] Preferably, each flow control member includes a center hole located at the center along its length direction and the above-mentioned fan blades that are evenly spaced circumferentially around the center hole. The shape of each fan blade is square, the angle between adjacent fan blades in each flow control member is 90°, and the connection between adjacent fan blades is a smooth transition.

[0016] Further, preferably, both ends of the center hole of each flow control member are respectively inserted with a connecting shaft, and each connecting shaft includes a horizontal section and a vertical section, wherein the free end of the horizontal section is inserted into the corresponding center hole, and the free end of each horizontal section is respectively fixed to the bottom of the corresponding drawer.

[0017] Preferably, the driving structures are respectively arranged at both ends of each guide layer, and each driving structure includes an electric push rod, a rack and a gear. The rack extends in a direction perpendicular to the length direction of each guide control member. The electric push rod is horizontally arranged and its free end is fixed to one end of the rack. The number of gears corresponds to the number of the guide control members, and each gear is respectively fixed on the horizontal section of the corresponding connecting shaft.

[0018] Further, preferably, four levers extending in the axial direction are arranged on the inner side surface of each gear at intervals along the circumferential direction with the center of the gear as the center, and each lever can be inserted into the gap between adjacent blades. The lever can provide a certain limit for the flow control member in two states, thereby ensuring the stability of the control state of the flow control member, and when the gear rotates, each lever can assist in driving the flow control member to rotate.

[0019] Preferably, it also includes a mounting frame for connecting each water collecting cover to the bottom of the corresponding drawer, the mounting frame is respectively arranged at the two ends of each guide layer, and each mounting frame includes a mounting cross bar extending in a direction perpendicular to the extension direction of each water collecting cover, and the mounting cross bar is provided with connecting columns corresponding to the water collecting covers of each guide layer at intervals along its length direction, and each connecting column is respectively fixed to the corresponding water collecting tank, and an assembly column is also fixed to the mounting cross bar, and the assembly column is fixed to the bottom of the corresponding drawer. Thus, each guide layer can be more firmly installed at the bottom of the corresponding drawer.

[0020] Compared with the prior art, the advantages of the present invention are: the heating device is arranged at the bottom of the disinfection inner tank, so the bottom wall of the disinfection inner tank can be heated by the effect of thermal radiation, and the heated bottom wall of the disinfection inner tank heats the air at the bottom of the disinfection inner tank by heat transfer. According to the chimney effect, the air produces a difference in air density due to the temperature difference, thereby forming a pressure difference, and then the air flows from bottom to top under the action of the pressure difference. Therefore, the heating device in the present invention heats the air at the bottom of the inner tank, and the generated hot air rises due to the pressure difference, forming a heat flow field from bottom to top in the disinfection inner tank. The hot air is guided from bottom to top into the guide gap through both sides of the first guide arc surface, and is guided to the top of the guide layer through the guide gap. It can be seen that the present invention can promote the hot air to rise from bottom to top, so that the hot air is evenly distributed around the tableware in each drawer, thereby improving the drying speed and disinfection effect. Furthermore, the above-mentioned flow guide gap can be opened and closed by the above-mentioned flow guide control member. In this way, when there are fewer tableware to be sterilized, the flow guide gap at the bottom of the upper drawer can be closed by the action of the flow guide control member, and the tableware can be placed on the lower drawer for disinfection, thereby saving energy and improving disinfection efficiency.

[0033] The present invention is further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 12 As shown, a tableware disinfection cabinet includes a disinfection inner container 1 with an opening at the front side, and a heating device 7 is arranged at the bottom of the disinfection inner container 1. In this embodiment, the heating device 7 is an electric heating tube. An upper drawer 11 and a lower drawer 12 are arranged above and below the disinfection inner container 1. In this embodiment, a guide layer 2 is arranged at the bottom of the upper and lower drawers 11, 12 respectively. Each guide layer 2 has a first guide arc surface 211, a guide gap 22 and a guide control member 3. Among them, the above-mentioned guide arc surface is located on the bottom surface of the guide layer 2 and protrudes downward, and there are at least two of the first guide arc surfaces 211 arranged in parallel, and the guide gap 22 is located between two adjacent first guide arc surfaces 211. The guide control member 3 is arranged above the guide gap 22, and the guide control member 3 can be driven by the driving structure 5 to open the guide gap 22 or be closed by the guide control member 3. In this embodiment, since the structures of the upper and lower drawers 11, 12 are the same, Figure 6 to Figure 12 Only the structure of the upper drawer 11 is shown.

[0035] The above-mentioned heating device 7 is arranged at the bottom of the disinfection liner 1, so that the bottom wall of the disinfection liner 1 can be heated by the effect of thermal radiation, and the heated bottom wall of the disinfection liner 1 heats the air at the bottom of the disinfection liner 1 by heat transfer. According to the chimney effect, the air produces a difference in air density due to the temperature difference, thereby forming a pressure difference, and then the air flows from bottom to top under the effect of the pressure difference. Therefore, the heating device 7 in the present invention heats the air at the bottom of the disinfection liner 1, and the generated hot air rises due to the pressure difference, forming a thermal flow field from bottom to top in the disinfection liner 1. The hot air is guided from bottom to top into the guide gap 22 through both sides of the first guide arc surface 211, and is guided to the top of the guide layer 2 through the guide gap 22. It can be seen that the present invention can promote the hot air to rise from bottom to top, so that the hot air is evenly distributed around the tableware in each drawer, thereby improving the drying speed and disinfection effect. Furthermore, the above-mentioned flow guide gap 22 can be opened and closed by the above-mentioned flow guide control member 3. In this way, when there are fewer dishes to be sterilized, the flow guide gap 22 at the bottom of the upper drawer 11 can be closed by the action of the flow guide control member 3, and the dishes are placed on the lower drawer 12 for sterilization, thereby saving energy and improving the sterilization efficiency. When fewer dishes are sterilized by ozone or other gases, the dishes can be placed on the lower drawer 12, and the flow guide gap 22 on the flow guide layer 2 at the bottom of the upper and lower drawers 11, 12 can be closed at the same time, so that the ozone can be confined in a relatively small space, thereby improving its sterilization effect on the dishes on the lower drawer 12.

[0036] The above-mentioned flow control member 3 can be implemented in a variety of ways. In this embodiment, the flow control member 3 is an impeller structure. The outer surfaces of each adjacent blade 31 of the flow control member 3 respectively constitute a smooth second flow guide arc surface 32. The above-mentioned flow guide layer 2 also has an upwardly open water collecting groove 210. The number of the water collecting grooves 210 corresponds one-to-one to the above-mentioned first flow guide arc surface 211, and each water collecting groove 210 is located at the upper part of the corresponding first flow guide arc surface 211. The above-mentioned flow control member 3 has at least two states during operation: the first state, two of the blades 31 of the flow control member 3 along the axial outer edges of the flow control member 3 are respectively against the corresponding top edges of the water collecting grooves 210 on both sides, and the above-mentioned flow guide gap 22 is closed; the second state, each blade 31 of the flow control member 3 is separated from the water collecting grooves 210 on both sides, and at least two of the blades 31 are located in the water collecting grooves 210 at the vertical projections of the water collecting grooves 210 on both sides. In this way, in the first state, the above-mentioned flow guide gap 22 is closed by the flow guide control member 3, so that the upper and lower drawers 11 and 12 can be separated from each other by the flow guide layer 2 at the bottom of the upper drawer 11. In the second state, the water droplets on the tableware in each drawer can drip onto the second flow guide arc surface 32 of the flow guide control member 3. As the flow guide control member 3 rotates, the water droplets dripping onto the second flow guide arc surface 32 are dripped into the water collection tank 210, so that the water droplets on the tableware in the upper drawer 11 can be prevented from dripping onto the lower drawer 12 and the water droplets on the upper and lower drawers 11 and 12 can be prevented from dripping onto the inner surface of the disinfection liner 1, thereby improving the user experience. Of course, the water droplets on the tableware can also drip directly into the water collection tank 210. Further, in order to enable each flow guide control member 3 to better close the corresponding flow guide gap 22 in the second state, a sealing strip 9 is provided on the top edge of the water collection tank 210 along its length direction, that is, in the second state, the outer edges of the corresponding fan blades 31 on each flow guide control member 3 are respectively against the corresponding sealing strip 9.

[0037] In this embodiment, the above-mentioned guide layers 2 all include water collecting covers 21, and each water collecting cover 21 extends in the left-right direction of the corresponding drawer. At the same time, the water collecting covers 21 in each guide layer 2 are arranged at intervals along the front-back direction of the corresponding drawer. Correspondingly, each of the above-mentioned flow control parts 3 also extends in the left-right direction of the drawer, and the flow control parts 3 of each guide layer 2 are also arranged at intervals along the front-back direction of the corresponding drawer, that is, in this embodiment, each water collecting cover 21 in each guide layer 2 and each flow control part 3 are arranged at intervals front and back and staggered up and down. The cross section of each water collecting cover 21 is arc-shaped and closed at both ends. The inner cavity of each water collecting cover 21 constitutes the above-mentioned water collecting tank 210, and the bottom surface of each water collecting cover 21 constitutes the above-mentioned first flow guide arc surface 211. Further, the cross section of the above-mentioned water collecting cover 21 is semicircular.

[0038] Further, in this embodiment, each flow control member 3 includes a center hole 30 located at the center along its length direction and the above-mentioned blades 31 spaced evenly along the circumferential direction with the center hole 30 as the center, and the shape of each blade 31 is square, and the angle between adjacent blades 31 in each flow control member 3 is 90° and the connection between adjacent blades 31 is smooth transition. The two ends of the center hole 30 of each flow control member 3 are respectively connected with a connecting shaft 4, and each connecting shaft 4 includes a horizontal section 41 and a vertical section 42, wherein the free end of the horizontal section 41 is connected to the corresponding center hole 30, and the free end of each horizontal section 41 is respectively fixed to the bottom of the corresponding drawer. Thereby, the flow control member 3 can rotate with the connecting shaft 4 at both ends as the fulcrum and the center axis as the center. In addition, the structural design of the above-mentioned flow control member 3 can make it rotate better under the action of the hot air flow from bottom to top, and at the same time, it can more smoothly guide the water droplets dripping on it into the water collection tank 210.

[0039] The driving structures 5 are respectively arranged at the two ends of each guide layer 2. Each driving structure 5 includes an electric push rod 51, a rack 52 and a gear 53. The rack 52 extends in a direction perpendicular to the length direction of each guide control member 3. The electric push rod 51 is arranged horizontally and its free end is fixed to one end of the rack 52. The number of gears 53 corresponds to the number of the guide control members 3, and each gear 53 is respectively fixed to the horizontal section 41 of the corresponding connecting shaft 4. In this embodiment, in order to enable the rack 52 to slide back and forth more smoothly, the left and right ends of the bottom of each drawer are respectively fixed with guide rails 54 extending forward and backward, and each rack 52 slides forward and backward along the corresponding guide rails 54. In this way, the rack 52 is driven to move forward and backward by the electric push rod 51, thereby driving the gear 53 to rotate, and then driving the guide control member 3 to swing and rotate, so as to realize the opening and closing of the guide gap 22.

[0040] In this embodiment, an action cycle of the flow control member 3 driven by the driving structure 5 includes the following steps: First, in the initial state, the outer edge of the corresponding fan blade 31 of each flow control member 3 abuts against the sealing strip 9 on the top edge of the corresponding water collecting tank 210, the flow guide gap 22 is closed, and the upper and lower layers are not connected, such as Figure 8 In the second step, the electric push rod 51 pushes the rack 52 backward, and the gear 53 rotates to drive the diversion control member 3 to rotate clockwise (rotate 90 degrees), and each fan blade 31 is separated from the corresponding water collection tank 210, and the diversion gap 22 is opened. At this time, the hot air can rise upward through the diversion gap 22, and the upper and lower layers are connected. The water droplets dripping on the diversion control member 3 are guided into the water collection tank 210, as shown in FIG. Fig. 9 In the third step, the electric push rod 51 continues to push the rack 52 to the maximum stroke (pushed to the rear end), and the diversion control member 3 rotates clockwise (continues to rotate 90 degrees) to re-close the corresponding diversion gap 22, and the upper and lower layers are not connected, as shown in FIG. Fig.10Step 4: The electric push rod 51 pulls back the rack 52, the diversion control member 3 rotates counterclockwise (90 degrees), and the diversion gap 22 is reopened, so that the upper and lower layers are connected. Fig.11 Step 5: The electric push rod 51 continues to pull the rack 52 back to the initial state, the diversion control member 3 rotates counterclockwise (90 degrees), the diversion gap 22 is closed again, and the upper and lower layers are not connected. Fig.12 The above actions are circulated in sequence, and the action of the flow control member 3 is regulated by the control structure 4 to open and close the flow control member 3 to the flow guide gap 22 .

[0041] Furthermore, four levers 531 extending in the axial direction are arranged on the inner side surface of each gear 53 at intervals along the circumferential direction with the center of the gear 53 as the center, and each lever 531 can be inserted into the gap between adjacent blades 31. The levers 531 can provide a certain limit for the flow control member 3 in two states, thereby ensuring the stability of the control state of the flow control member 3. At the same time, when the gear 53 rotates, each lever 531 can assist in driving the flow control member 3 to rotate.

[0042] In order to enable each guide layer 2 to be more firmly installed at the bottom of the corresponding drawer, the present embodiment also includes a mounting frame 6 for connecting each water collecting cover 21 to the corresponding drawer bottom. The mounting frame 6 is respectively arranged at both ends of each guide layer 2, and each mounting frame 6 includes a mounting cross bar 61 extending in a direction perpendicular to the extension direction of each water collecting cover 21. The mounting cross bar 61 is provided with connecting columns 62 corresponding to the water collecting covers 21 of each guide layer 2 at intervals along its length direction, and each connecting column 62 is respectively fixed to the corresponding water collecting tank 210. An assembly column 63 is also fixed on the mounting cross bar 61, and the assembly column 63 is fixed to the bottom of the corresponding drawer.

[0043] In addition, the above-mentioned disinfection inner tank 1 is provided with an ultraviolet lamp 8. In this embodiment, there are two ultraviolet lamps 8 and they are arranged up and down on the back plate of the disinfection inner tank 1. After the tableware to be disinfected is placed in each drawer, the gap between the tableware is a blind spot for ultraviolet disinfection. Therefore, in this embodiment, the exposed surfaces of each guide layer 2 are all reflective surfaces, so that the ultraviolet rays irradiated on the guide layer 2 can be reflected and focused by the reflective surface on the outer surface of the guide layer 2, thereby increasing the irradiation range of the ultraviolet rays and enhancing its irradiation intensity, thereby enhancing the disinfection effect of the ultraviolet rays. In this embodiment, the inner and outer surfaces of each of the above-mentioned water collection covers 21 are reflective surfaces, and the surfaces of each guide control component 3 are also reflective surfaces.

[0044] It can be seen that in the present invention, the driving structure 5 drives the flow control member 3, so that the back-and-forth swinging rotation of the flow control member 3 can be realized, which not only can realize the opening and closing of the flow guide gap 22, but also can generate a certain wind field through rotation, thereby promoting the drying of tableware, and can promote the hot air to rise from the bottom to the top through the certain negative pressure generated by the rotation. In addition, through the swinging rotation, the various surfaces thereon can dynamically reflect ultraviolet rays, so that the ultraviolet rays are irradiated to various parts of the disinfection inner tank 1, further enhancing the disinfection effect of the ultraviolet rays. In addition, the swinging rotation can promote the uniform mixing of disinfection gases (such as ozone, etc.), thereby further improving the disinfection effect.
