Description

Cup body assembly of cooking machine

Technical Field

The utility model relates to kitchen electrical parts, in particular to a cup body assembly of a cooking machine.

Background

The glass cup body is used by the existing more and more cooking machines, and in the aspect of pulping visibility, the glass cup body is greatly convenient for consumers to monitor the whole pulping process, and the pleasure and frequency of the consumers in using the cooking machines are further improved. However, the existing glass broken food machine is formed by die casting single-layer glass, the glass thickness reaches 6mm, the weight of the whole glass is heavier, and the weight of the glass is further increased after the glass is filled with food materials, so that the glass is not beneficial to taking and pouring of users. Meanwhile, the glass cup body is of a single-layer structure, so that the glass cup body is inconvenient for a user to hold with both hands, and the problem of scalding the hands is solved. Moreover, the wall breaking machine has the problem of large pulping noise in the pulping process, which is also a problem that the existing wall breaking machine is difficult to overcome.

To overcome the above problems, research and development personnel in the art continue to improve the food processor. However, it is still difficult to provide a perfect solution to compromise the portability, visibility, burn-out protection, low noise of the consumer needs. For example, in order to reduce the weight of the cup body and meet the requirement of visual monitoring, research and development personnel think that the cup body is manufactured by using light pipe material glass, but the light pipe material glass is easy to crack, and corresponding shell cover is needed for protection, so that the cup body of the food processor cannot achieve the visual purpose, and the problems of water inflow and slag inflow in an interlayer, bacteria breeding and peculiar smell generation are easy to exist. On the other hand, if the cup body adopts a double-layer vacuum glass cup to realize visualization, the manufacturing cost is high, the finished product rejection rate is higher by the existing mature process, and the batch production of the food processor cup body is difficult to realize.

Based on the above problems, the applicant has previously provided an inventive patent application with application number CN 201120510508.8. The patent discloses a scheme of adopting a glass inner cup and a transparent plastic shell as a composite cup body of a soymilk machine, wherein the upper side and the lower side of an interlayer space formed between the inner cup and the shell are sealed. Can prevent external water and slurry slag from entering the interlayer space, and can meet the purposes of visibility, scalding prevention, portability and noise reduction required by consumers. However, the applicant found that in the process of continuous research, the sealing gaskets are arranged at the upper end and the lower end of the interlayer space to seal, the interlayer space is in a closed state, and in the process of assembly, after air in the interlayer space is extruded, the sealing gaskets at the upper end and the lower end of the interlayer space are easy to fall off. In addition, in the process of making soymilk by using soymilk machine, after the air in the interlayer space is subjected to expansion with heat and contraction with cold, the sealing structures at the upper end and the lower end of the interlayer space are extruded, and the problem of sealing failure of the interlayer space is easily caused after long-term use. Meanwhile, the applicant also finds that the air in the interlayer space can condense water vapor or water drops after being subjected to thermal expansion and cold contraction, and cannot be removed, so that the visual monitoring of consumers is particularly influenced in the soymilk making process of the soymilk machine.

Wherein, the shielding piece 5 is a handle with the upper end hooked on the cup mouth of the inner cup 11 and the lower end fixed with the outer shell 12, and the handle comprises a handle base body 51 and a handle cover 52, the communication cavity 50 is formed by enclosing the handle base body 51 and the handle cover 52, and a communication hole 510 for communicating the communication cavity 50 with the outside is arranged on one side of the holding part 511 of the handle towards the outer shell 12, when the user grasps the handle, the communication hole 510 can be partially shielded, and when the cup assembly is prevented from being cleaned, external water enters into the communication cavity 50 through the communication hole 510.

For this embodiment, after adopting above-mentioned technical scheme, interior cup and shell all can perspective, and be formed with annular sound insulation intermediate layer between interior cup and the shell, the sound insulation intermediate layer both can protect, insulate against heat and prevent scalding interior cup, still has certain noise reduction effect, can reduce the in-process of slurrying, and the noise that the material impacted interior cup produced is outwards conducted. Wherein, the upper end of the sound insulation interlayer is a closed end, and when the slurry is poured, the slurry, slurry slag and the like in the inner cup enter the interlayer. More importantly, in the embodiment, the side wall of the shell is provided with the vent hole and the handle covered outside the vent hole, the handle and the shell are fixed together, the vent hole is hidden between the handle and the shell, the handle is provided with a communication cavity communicated with the outside, and the vent hole is used for communicating the sound insulation interlayer with the communication cavity. Because the sound insulation interlayer is of a closed structure at the upper end and the lower end, the ventilation holes are formed in the shell in the assembly process, so that the ventilation of the sound insulation interlayer can be more convenient, and the closed installation of the inner cup and the shell is more facilitated. And in the process of making pulp by a cooking machine, in the process of heating liquid in the inner cup to boiling by the heating device, heat of a part of liquid in the inner cup can be conducted into the sound insulation interlayer, so that the temperature of air in the sound insulation interlayer is increased, the temperature is increased to cause expansion of the air in the heat insulation interlayer, and the pressure in the sound insulation interlayer is obviously increased. The expanded air can be discharged to the outside through the air holes, the communicating cavities and the communicating holes, so that the pressure in the sound insulation interlayer is always balanced with the outside, and the problems of broken inner glass and sealing failure caused by the increase of the pressure in the sound insulation interlayer can be avoided. Obviously, the air holes in the embodiment have the function of adjusting the internal and external pressure of the sound insulation interlayer.

Meanwhile, in the pulping process, the heating device is switched between heating and stopping for a plurality of times, air in the sound insulation interlayer can absorb and release heat repeatedly, residual moisture in the sound insulation interlayer can be evaporated and condensed repeatedly to form water vapor, so that the surfaces of the outer shell and the inner cup of the sound insulation interlayer are blurred, and the pulping condition of the food processor is not easy to observe by consumers through the outer shell and the inner cup. Moreover, because the sound insulation interlayer is narrow in space and airtight, water vapor and water drops condensed in the sound insulation interlayer can not be directly removed by consumers, and the visibility of the consumers can be continuously influenced in the subsequent pulping process. The ventilation holes are formed in the shell, hot air and hot steam in the sound insulation interlayer can be effectively discharged to the outside atmosphere through the ventilation holes, so that even if the heating device repeatedly heats and stops in the pulping process, the hot air and the steam in the sound insulation interlayer can not be condensed into water vapor and water drops, and visual demands of consumers are affected. Particularly, as the air holes are formed in the upper closed end close to the sound insulation interlayer, and the hot air and the hot steam rise and the cold air fall, the water vapor in the sound insulation interlayer can be discharged through the air holes better, and the water vapor cannot stay in the sound insulation interlayer.

In addition, even if cleaning water or foreign matters do not enter the communicating cavity of the handle, the cleaning water or the foreign matters can only accumulate in the communicating cavity, and cannot enter the sound insulation interlayer directly through the air holes, so that the problem that foreign matters in the sound insulation interlayer cannot be removed is effectively solved, and the maintainability of the food processor is greatly improved. In addition, in the embodiment, the communicating hole for communicating the communicating cavity with the outside is arranged on the holding part of the handle, so that when a person holds the holding part in the cleaning process, water drops which splash can be prevented from entering the communicating cavity through the communicating hole, and the communicating cavity in the handle is in a bending state, so that the entering of external foreign matters into the sound insulation interlayer through the ventilation holes is further limited.

In this embodiment, the ventilation hole is closer to the upper closed end to better discharge hot air and hot steam, so as to avoid condensation into water vapor and water drops. Of course, for the present embodiment, the preferred arrangement of the vent is such that the distance between the vent and the upper closed end is no greater than 10mm. In order to efficiently realize convection between air in the sound insulation interlayer and the outside, a certain relationship exists between the area size S1 of the air holes and the volume size V1 in the sound insulation interlayer. The present inventors have found thatAs a result of research, when S1/V1 is less than 0.1mm ² In the process of pulping and heating, the air and water vapor in the sound insulation interlayer are difficult to discharge, the pressure in the sound insulation interlayer is obviously increased, and the air holes are difficult to play a role in balancing the pressure. Moreover, after the steam is condensed, more water vapor and water drops still gather on the inner wall of the sound insulation interlayer, so that the perspective observation of consumers is influenced. And when S1/V1 is greater than 1.4mm ² When/ml, in the process of pulping suspension, the outside moist air can entrain more moisture to enter the sound insulation interlayer through the air holes, so that the perspective monitoring of the next pulping consumers is affected. Therefore, for the present embodiment, S1/V1 is required to be limited to 0.1mm ² /ml～1.4mm ² In ml, the preferred value of this example is 0.5 to 1. Based on this, for the present embodiment, the area S1 of the ventilation holes is selected to be 10 to 140mm ² 。

It should be noted that, the mounting structure of the inner cup and the outer shell is not limited to the solution disclosed in this embodiment. For example, the inner side wall of the shell is provided with an inward annular pressing edge, the inner cup is installed in the lower end opening of the shell, and the cup opening of the inner cup is in sealing fit with the lower end face of the annular pressing edge to form an upper closed end. Or, the cup mouth of the inner cup is provided with an outward annular flanging, the inner cup is installed in the upper end opening of the shell, and the annular flanging is lapped on the cup mouth of the shell and is matched with the cup mouth of the shell in a sealing way to form an upper closed end. Also, with the present embodiment, the fixed relationship of the handle and the housing is not limited to the solution disclosed in the present embodiment. The handle and the shell can be integrally formed, or the handle base body and the shell can be integrally formed. Of course, the shielding member in this embodiment is not limited to the handle, and may be other members having a function of shielding the ventilation holes. It should be noted that in this embodiment, the communicating hole and the ventilation hole are preferably arranged in a staggered manner, and the main purpose is to prevent water or other foreign matters from entering the sound insulation interlayer through the ventilation hole when the cup body is cleaned. Of course, the water blocking rib in this embodiment is also used for blocking water, so as to prevent external water or condensed water in the communication cavity from entering the sound insulation interlayer through the air holes along the outer side wall of the shell. If the side wall of the shell is provided with a convex column which protrudes outwards and stretches into the communication cavity, and the vent holes penetrate through the convex column, the convex column also has a water retaining effect.

In this embodiment, the inner cup is a vertically penetrating glass cup, and of course, the inner cup may be a glass cup having a bottom wall of the container, and in this case, the heating device may be a heating film that covers the bottom wall of the glass, and the bottom wall of the inner cup of the glass is heated by the heating film. Moreover, in this embodiment, the sound insulation interlayer may not be a closed structure, for example, the lower end of the sound insulation interlayer has an opening, and the opening of the lower end is provided with dustproof cotton, so that the opening of the lower end of the sound insulation interlayer can more easily realize air convection inside and outside the sound insulation interlayer, and the dustproof cotton can isolate external dust from entering the sound insulation interlayer, so as to prevent the problem of perspective blurring caused by dust pollution to the sound insulation interlayer. Of course, in order to solve the problem that the water vapor in the sound insulation interlayer is fuzzy and influences the perspective function, a drying agent, a drying device, a circulating fan or the like can be arranged in the sound insulation interlayer to further absorb the water vapor or accelerate the circulating discharge of the water vapor. In this embodiment, the ventilation holes are not limited to round holes, square holes, rectangular holes, and the like, and the ventilation holes may be ventilation grooves provided along the handle direction.

It should be noted that the above structural changes and parameter selection of the present embodiment may also be applied to other embodiments of the present utility model.

In addition, in order to reduce cooking machine operational noise, current cooking machine adopts double-deck cup structure more, has following problem when its use: when the cup body just finishes making hot drink, if the user washs the cup body immediately at this moment, can lead to the cup body to cool down sharply, the air contraction in the sealed chamber between inside and outside cup leads to inside and outside pressure differential increase, outside pressure is obviously more than inside pressure, and the washing water gets into the sealed chamber through the weakest position of the sealed of rim of a cup sealing washer and/or bottom of a cup sealing washer this moment easily, and will produce steam in the sealed chamber when making hot drink next time, causes sealed intracavity to form fog and water droplet, influences user experience. Meanwhile, in the process of continuously expanding with heat and contracting with cold of the sealing cavity, acting force is continuously applied to the sealing ring, so that deformation and failure of the sealing ring are easily accelerated, and the service life of the sealing ring is shortened. Moreover, if the sealing rings between the inner cup and the outer cup are too tight and are easy to deform, the sealing is insufficient, water is easy to enter the sealing cavity, and high sealing requirements are provided for the sealing structure.

The pressure regulating device can be arranged, so that on one hand, the sealing requirement of the inner and outer cup sealing structure can be reduced, the use reliability of the inner and outer cup sealing structure is ensured, and the service life of the inner and outer cup sealing structure is prolonged; on the other hand, the water inlet in the sealing cavity can be prevented, and the sealing effect and the visual effect are prevented from being influenced due to continuous expansion and contraction of heat and cold in the sealing cavity.
