Description

Multilayer drawer type tableware sterilizer

Technical Field

The invention relates to the field of kitchen appliances, in particular to a multilayer drawer type tableware disinfection cabinet.

Background

Only good disinfection equipment can ensure that people ingest food of the body to be healthy and sanitary. As one of the important electric appliances in modern kitchens, the disinfection cabinet will show a continuously and steadily increasing situation in the coming years, and the industry of the disinfection cabinet is gradually developed and matured. The disinfection cabinet is a tool for drying, sterilizing, preserving heat and dehumidifying tableware, tableware and other articles in the modes of ultraviolet rays, far infrared rays, high temperature, ozone and the like, and is generally box-shaped, and most of the cabinet body is made of stainless steel. In recent years, with the rapid development of the disinfection cabinet market, the embedded drawer disinfection cabinet is more and more appeared in the daily life of people due to the characteristics of compact installation, kitchen space saving, attractive appearance and the like. However, the conventional disinfection cabinet mainly has the following problems during the application process.

1. Conventional disinfection cabinets mostly use independent disinfection modes, such as: ultraviolet ray, far infrared ray, high temperature, ozone, etc. and because of the specificity of germ, the independent disinfection mode often can not accomplish the universal kill to different kind germ, and then influences the result of use of sterilizer. For the embedded disinfection cabinet, due to the limited layout space and the consideration of installation of each functional module, the rationality of the overall layout is very important, which is yet to be improved on the conventional disinfection cabinet.

2. The dish rack of the traditional disinfection cabinet usually adopts a stainless steel dish rack, and although the dish rack has a simple structure, the dish rack has high hardness, so that dishes with patterns such as gold stamping and printing are easily worn in the long-term use process, and the overall appearance of the dishes is influenced. Meanwhile, the size of the slot of the conventional dish rack is fixed, and the conventional dish rack is poor in universality and narrow in application range for different dishes.

3. In order to meet the placing requirements of dishes, bowls and other tableware and ensure the intervals of the tableware to meet the sterilization conditions of radiation surfaces, ventilation surfaces and the like, a dish rack, a bowl rack and the like are usually arranged inside a drawer of the disinfection cabinet. When the tray rack is used, a user places the trays in the slots of the tray rack one by one, takes out the sterilized trays from the slots one by one after a batch of trays are sterilized, and then places a new batch of trays in the slots again; however, in this method, since the complicated steps of removing the sterilized dishes and restacking the dishes are required, it is inconvenient in the actual use process, and especially, a lot of time is wasted in the case of large amount of dishes. If the disinfection cabinet can directly stack the dishes for standby after disinfection, the problem can be effectively solved.

Meanwhile, the far infrared radiation lamp tube 7 and the ultraviolet radiation lamp tube 6 are distributed at intervals, and the whole virus killing area of the disinfection chamber 4 has balanced killing performance. The underneath type ozone generator 12 is adopted, and ozone is installed at a low position to form a balanced filling mode in the disinfection chamber 4, so that the probability of low-concentration dead angles of the ozone is reduced, and the disinfection effect is further ensured.

In a second aspect, the tray frame adopted by the invention has great advantages compared with the traditional stainless steel tray frame. As shown in fig. 2, a transverse third partition 15 is disposed in the middle of the sterilizing chamber 4, and the third partition 15 divides the sterilizing chamber 4 into an upper layer and a lower layer. The upper layer is mainly used for placing dishes at intervals for irradiation disinfection, and the lower layer is mainly used for placing a dish stack. Drawers which are provided with no end plates at two ends and are U-shaped in section are arranged in the upper layer and the lower layer of the disinfection chamber 4, and the drawers are in sliding fit with the cabinet body 1. Since the cabinet 1 and the drawer are slidably engaged by sliding rails, which is a conventional design similar to the product, and is not directly related to the actual improvement scheme of the present invention, it is not described herein again. In the first drawer 16 of the present invention, which is positioned at the upper layer of the sterilizing compartment 4, a tray rack 17 for separately placing dishes at the time of sterilization is provided. A storage mechanism for the stacked dishes is provided in the second drawer 18 located at the lower level of the sterilizing compartment 4.

Referring to fig. 2 to 4, the tray frame 17 includes a plurality of sets of placement components disposed on two inner sidewalls of the first drawer 16 and uniformly distributed along a length direction of the first drawer 16, and the placement components disposed on the two inner sidewalls of the first drawer 16 are symmetrically distributed. Two sides of the plate are respectively inserted into the two corresponding placing components on the side wall. Each group of the placing assemblies comprises two side plates 19 arranged on the inner side wall of the first drawer 16, the side plates 19 extend vertically, and arc-shaped bent parts are arranged at the bottoms of the side plates 19. The edge plate 19 is usually formed directly on the inner wall of the first drawer 16, but may be mounted by bolting or snapping, and serves as a base for mounting the airbag cushion 20.

The two side plates 19 are internally provided with air bag supporting pads 20 matched with the side plates 19 in a clamping way, and the lower ends of the air bag supporting pads 20 are also provided with bending parts for supporting the lower parts of the plates. The airbag cushion 20 extends beyond the edge panel 19, and the area beyond the edge panel 19 constitutes a clamping support for the airbag cushion 20. That is, the portion of the bladder pad 20 beyond the edge of the side panel 19 serves as the primary location for the bladder pad 20 to hold and support the dish. The holding and supporting part of the air bag supporting pad 20 is provided with a supporting groove 21 extending along the length direction of the air bag supporting pad 20, and the plate is clamped in the supporting groove 21. An air outlet 22 is arranged at the top of the air bag support cushion 20, and a first pressure valve 23 is arranged at the air outlet 22. When the air bag pad 20 is pressed, the pressure inside the air bag pad 20 is increased, the first pressure valve 23 is opened, and the gas inside the air bag pad 20 is discharged from the gas outlet 22, thereby adapting to the dishes with different thicknesses.

In use of the invention, the tray is vertically inserted into the bracket 21 of the airbag cushion 20 on which the assembly is placed. As the air bag support pad 20 has flexibility and elasticity, the air bag support pad 20 can be stably inserted into dishes with different thicknesses, and the universality is stronger. Meanwhile, the air bag support cushion 20 has flexibility, so that the situation that rigid friction exists between the traditional dish rack and the dish is changed, and the air bag support cushion has certain protection for the rare dish with patterns such as gold stamping, printing and the like.

Of course, after the air in the airbag cushion 20 is exhausted, when it is necessary to adapt to a thinner dish, the airbag cushion 20 should be inflated to ensure that the width of the bracket 21 is appropriate, so the airbag cushion 20 of the present invention should have an inflated structure. However, in consideration of the large number of the airbag cushion pads 20, in order to improve the convenience of inflation, as shown in fig. 3, two adjacent airbag cushion pads 20 of the present invention are communicated with each other through a short air pipe 24, a check valve 25 is provided on the short air pipe 24, and the check valve 25 has one-way conductivity. Referring to fig. 2 and 3, the one-way valve 25 is in one-way communication from left to right, and one of the left ends of the two airbag cushions 20 at the two ends of the tray frame 17 is connected to the output end of the air pump through a connecting pipe. For the dishes which are not drained after being partially washed, in order to avoid water from directly falling on the first drawer 16, a water collecting tray can be further arranged at the bottom of the first drawer 16, the water collecting tray can be detachably connected and is convenient to take down, and the water collecting tray is mounted on the tray in a manner that the function of other devices is not influenced.

In a third aspect, the invention can also automatically arrange the sterilized dishes, and compared with the traditional method which only can manually arrange, the invention is more convenient to use. As shown in fig. 2 and 5-10, the sterilizing chamber 4 of the present invention is further provided with a collating device for stacking and transferring the dishes on the dish rack 17 to a storage mechanism. The arranging device comprises a stacking mechanism for stacking the plates on the plate rack 17, a conveying mechanism for conveying the stacked plates to the storage mechanism, and a transferring mechanism for transferring the stacked plates from the stacking mechanism to the conveying mechanism.

The stacking mechanism and the plate rack are more in specific forms, and the tray can be placed and stacked separately as long as the stacking mechanism and the plate rack are matched with each other in a cooperative mode. For example: the tray frame can be a slot, the stacking mechanism is a multi-shaft mechanical arm, and stacking is achieved through the cooperation of the multi-shaft mechanical arm and the clamp.

Referring to fig. 2 and 6-8, the stacking mechanism includes a first pushing arm 26 and a second pushing arm 27, the first pushing arm 26 is fixedly disposed on the cabinet 1 at one end of the first drawer 16 close to the transfer mechanism, as shown in fig. 2, the transfer mechanism is located at the left end of the cabinet 1, and then the first pushing arm 26 is fixedly disposed at the left end of the cabinet 1. The second pushing arm 27 is located on the cabinet 1 near the other end of the first drawer 16, that is, the cabinet 1 near the right end in fig. 2, and can reciprocate toward or away from the first pushing arm 26 under the driving of the first driving assembly. The second pushing arm 27 is close to the first pushing arm 26, so that the dishes can be pushed toward the first pushing arm 26 to be stacked, that is, the dishes on the dish rack 17 are pushed by the second pushing arm 27 to be stacked during the movement of the second pushing arm 27 toward the first pushing arm 26.

The first driving assembly may have a specific structure as long as the second pushing arm 27 can be driven to stably move toward the first pushing arm 26. As shown in fig. 6 and 7, the stacking device comprises a screw 28 and a guide rod which are arranged on the bottom surface of the first partition board 2 side by side and extend along the length direction of the first partition board 2, two ends of the screw 28 are respectively installed on an installation seat 29 on the bottom surface of the first partition board 2 and form a rotating fit with the installation seat 29, the screw 28 is in transmission connection with a stacking motor 30, and two ends of the guide rod are fixedly arranged on the installation seat 29. The first driving assembly further comprises a sliding block 31, wherein the sliding block 31 is provided with a threaded hole and a guide hole which are matched with the screw rod 28 and the guide rod, and the threaded hole and the guide hole are sleeved on the screw rod 28 and the guide rod. The first pushing arm 26 is fixedly arranged on the mounting seat 29, and the second pushing arm 27 is fixedly arranged on the sliding block 31. The second pushing arm 27 is driven to move by the action of the lead screw 28, so that stacking is realized. In order to improve the stability of the first pushing arm 26 and the second pushing arm 27 in pushing and clamping the plate, as shown in fig. 8, it is better to make the first pushing arm 26 and the second pushing arm 27 in an inverted Y shape, and the two ends of the inverted Y shape and the intersection point of the two branches of the inverted Y shape are provided with a hemispherical first rubber contact 32.

Certainly, the stacking mechanism is required to realize the function, the structure of the tray frame is also important, the tray frame can be used for facilitating stable and spaced placement of the trays during disinfection, and the locking of the trays can be released successively when the second pushing arm 27 pushes the trays, so that the trays can be stacked stably under pushing, and the normal pushing of the second pushing arm 27 is not influenced. Therefore, in the case of using the stacking mechanism, the tray of the present invention may be the above-described airbag type tray.

When adopting above-mentioned gasbag formula plate rail, gasbag formula plate rail when compressed, can change its form according to the inside inflation situation of gasbag pad 20, guarantee the stable centre gripping to the plate when aerifing, can remove the centre gripping to the plate again after the gassing, consequently, the plate rail of this kind of mode is simple structure not only, also for follow-up through the propelling movement realize laying a yard to the plate and having laid the basis, the normal work of the mechanism of being convenient for stacking. The specific working process is as follows: the stacking motor 30 works to drive the lead screw 28 to rotate, the lead screw 28 rotates to drive the sliding block 31 to slide along the lead screw 28, and further drives the second pushing arm 27 to push the plate, after the plate is extruded, acting force is applied to the air bag support pad 20, the internal pressure of the air bag support pad 20 is increased, the first safety valve 23 at the exhaust port 22 is opened, and gas in the air bag support pad 20 is exhausted through the exhaust port 22; the clamping of the plate is released after the air bag supporting cushion 20 is exhausted; as the second pushing arm 27 continues to move, the tray is separated from the original airbag cushion 20 and pressed against the next airbag cushion 20 and tray. After successive pushing, all the dishes are finally stacked at one end close to the first pushing arm 26 and are clamped by the first pushing arm 26 and the second pushing arm 27 together, so that stacking of all the dishes is realized. After the stacked dishes are transported away, the air-entrapping pump is started to re-inflate the air bag support cushions 20 step by step, and then the next disinfection cycle is started.

Of course, other types of tray structures than the above-described air bag tray can be used in the present invention, such as: the plate rail is the cardboard, and the plate is inserted and is established between the cardboard, and the cardboard can adopt thick size cardboard, and its border towards the plate is inverted triangle-shaped, pushes away the in-process that arm 27 propelling movement at the second, utilizes a cylinder or linear motor drive cardboard to withdraw from between the plate one by one, and then realizes folding the sign indicating number. However, the structure is relatively complex because the problem that the clamping plates are withdrawn successively needs to be considered, and the equipment cost is high due to the adoption of the multi-shaft mechanical arm for stacking. Therefore, the invention preferably adopts the mode that the air bag type tray frame is matched with the stacking mechanism, and the trays are stacked after the sterilization of the trays is finished.

In addition to the above structure, how to take off the stacked plate stacking mechanism and place the stacked plate stacking mechanism on the conveying mechanism is also an important component of the sorting device of the invention. As shown in fig. 9, the transfer mechanism includes two parallel mounting plates 33 fixedly disposed on the side wall of the cabinet 1, a rotating shaft 34 is disposed between the end portions of the mounting plates 33, two ends of the rotating shaft 34 are mounted on the mounting plates 33 and form a rotating fit with the mounting plates 33, and the rotating shaft 34 is in transmission connection with the transfer motor. The middle section of the rotating shaft 34 is fixedly connected with one side edge of the L-shaped plate 36 through the triangular plate 35. The other side edge of the L-shaped plate 36 is provided with a first clamping rod 37 and a second clamping rod 38 which can be driven by a second driving component to close or separate along the length direction of the side edge of the L-shaped plate 36, and the opposite surfaces of the first clamping rod 37 and the second clamping rod 38 are correspondingly provided with a second rubber contact 39.

During operation, the transfer motor drives the rotating shaft 34 to rotate, so as to drive the triangular plate 35 and the L-shaped plate 36 to move, and further drive the fixture, that is, the first clamping rod 37 and the second clamping rod 38 to rotate to the tray frame, and the first clamping rod 27 and the second clamping rod 38 are driven by the second driving assembly to close together, so as to clamp the tray stack clamped on the stacking mechanism. After the stable clamping, the stacking mechanism retreats, then the transfer motor moves again to drive the clamp to rotate to the lower part, and the plate stack is placed on the conveying mechanism and conveyed to the storage mechanism by the conveying mechanism.

The second driving assembly has more specific structures, for example: 1. as shown in fig. 9 and 10, the second driving assembly includes a screw 40 mounted on the L-shaped plate 36, extending along the length direction of the side of the L-shaped plate 36, and forming a rotation fit with the L-shaped plate 36, and the screw 40 is in transmission connection with a clamping motor 41. Two ends of the screw rod 40 are respectively sleeved with a nut 42 which is in threaded fit with the screw rod 40, and the thread directions of the screw rod 40 in the areas where the two nuts 42 are located are opposite.
