Description

Diversion structure of the dish dryer

The present invention belongs to the technical field of bowl dryers, and particularly relates to a diversion structure of a bowl dryer.

Dish dryers are commonly found in ordinary households. They are mainly used to place the dishes that have just been cleaned. Then, through the drying function of the dishwasher, the damp dishes are dried to reduce the time when the dishes are wet, thereby inhibiting the dampness of the dishes. The growth rate of bacteria on the washed dishes; the current dish dryer is to strengthen the disinfection function, and the dish dryer is usually equipped with a disinfection device. There are three types of disinfection devices, including ozone disinfection, ultraviolet disinfection and high temperature disinfect. Some dish dryers are even equipped with multiple disinfection devices to provide multiple types of disinfection.

The aforementioned high-temperature disinfection is performed at a high temperature of 120 degrees or more, but it will damage some items that are not heat-resistant, such as cutting boards, wooden and plastic tableware. Ozone disinfection is disinfection with high concentration of ozone, which is suitable for most tableware and has the advantage of high sterilization ability. However, after ozone disinfection is used, ozone will remain on the tableware for a period of time, and as long as the ozone exceeds a certain concentration, it will Hazardous to the human body. Ultraviolet disinfection can only be used to disinfect the surface of tableware due to penetrability problems, and it is difficult to disinfect deeply deformed tableware.

The main reason for the installation of the disinfection device in the aforementioned dish dryer is mostly attributed to the uneven drying function. After the general dish dryer is dried, the interior of the dish dryer is still in a humid state, and it is easy to corrode the inside of the dish dryer due to moisture. The steel frame and slide rails also cause bacteria to grow inside the dishwasher. Therefore, it is necessary to install a disinfection device to help compensate for the lack of drying function.

The main structure of the aforementioned dish dryer is to have a casing and an inner container installed in the casing. Since the top surface and both sides of the inner container are not in contact with the casing, there is formed between the casing and the inner container. Inverted U-shaped space, in addition, a plurality of small holes are pierced on both side walls of the liner, so that the space between the cabinet and the liner is connected with the space where the dishes are placed in the liner, and then between the cabinet and the liner A drying device is arranged in between, and the drying device is located above the inner container.

With the aforementioned structure, when the drying device is activated, hot air flows from the top of the inner container to the outer sides of the inner container, and then enters the inner container through a plurality of small holes to dry the dishes inside the inner container.

It is worth mentioning that when the hot air flows from the top of the inner tank to the side, the air flow is perpendicular to the opening direction of each small hole, so that the air flow through the small holes is low and the velocity is low. The low flow rate and low flow rate make the drying effect of the dishes poor. Often after the drying is completed, the bottom of the inner tank is still wet, causing bacteria to breed in the inner tank. Therefore, an additional disinfection device is needed to solve the insufficient drying. problem.

However, the use of disinfection devices to solve the bacteria problem caused by humidity not only greatly increases the cost of the dish dryer, but also reduces the use space of the dish dryer. In view of this, it is indeed necessary to solve the shortage of the drying device of the dish dryer. The problem.

The purpose of the present invention is to solve the problem of insufficient drying part of the dish dryer.

In order to achieve the foregoing objective, the present invention is a diversion structure of a dish dryer, which includes:

A housing with two opposite inner side surfaces, and an inner top surface and an inner bottom surface connected to the two inner side surfaces and opposite to each other;

A partition plate is assembled in the casing and connected to the two inner side surfaces, a first space is defined between the partition plate and the inner top surface, and a second space is defined between the partition plate and the inner bottom surface Space, and the partition plate is provided with a perforation, and the perforation communicates with the first space and the second space;

A drying device assembled in the first space;

A guide path is assembled on the partition plate and surrounds the perforation, the guide path has a long side and a short side opposite to each other, and the short side is located between the long side and one of the inner sides, and An acute angle is sandwiched between the side of the long side close to the short side and the partition plate, and an obtuse angle is sandwiched between the side of the short side close to the long side and the partition plate.

In a preferred embodiment, the direction in which one of the inner side surfaces extends to the other inner side surface is a horizontal direction, and the number of the perforations is two, and the two perforations are arranged along the horizontal direction.

In a preferred embodiment, the drying device mainly has a fan and two heating tubes.

In a preferred embodiment, the direction in which one of the inner side surfaces extends to the other inner side surface is a transverse direction, and the number of the perforations is two, and the second perforations are arranged along the transverse direction, the partition plate An air suction port is further provided between the two perforations, the air suction port communicates with the first space and the second space, and the fan corresponds to the air suction port.

In a preferred embodiment, the drying device further has two heating stations, the two heating stations are assembled on the partition plate, and the two heating tubes are respectively placed on the two heating stations.

In a preferred embodiment, each of the two heating stations has a drainage surface inclined toward the fan.

It can be understood from the foregoing structure that the guidance of the two guide passages can avoid the suction of the fan, so that the high-temperature wind can flow directionally toward the inner bottom surface, which effectively raises the temperature in the second space. After the air flow passes through the inner side and the inner bottom surface, the air flow will merge into the upward air flow towards the fan. It is attracted by the fan and returns to the first space more quickly to reheat. Not only the high temperature wind can effectively reach the bottom of the second space, but also the air flow. It can also quickly return to the first space, so that the air flow can be repeatedly heated to achieve a rapid heating effect, so that the temperature of the second space can be raised high enough to dry the dishes, and at the same time solve the problem of bacterial growth, and no additional sterilization is required Device.

Please refer to Figures 1 to 3, a diversion structure of a dish-drying machine, which mainly has a casing 10, a partition plate 20, a drying device 30 and a guide channel 40, in which:

The casing 10 has two opposite inner side surfaces 11, and an inner top surface 12 and an inner bottom surface 13 that are connected to the two inner side surfaces 11 and are opposed to each other; in this embodiment, both ends of the two inner side surfaces 11 are respectively connected to the The inner top surface 12 and the inner bottom surface 13 form a rectangular space.

The partition plate 20 is assembled in the casing 10 and connected to the two inner side surfaces 11, a first space A is defined between the partition plate 20 and the inner top surface 12, the partition plate 20 and the inner bottom surface A second space B is defined between 13 and the partition plate 20 is penetrated with a perforation 21 which communicates with the first space A and the second space B; in this embodiment, one of the inner side surfaces 11 The direction extending to the other inner side surface 11 is a transverse direction X, and the number of the perforations 21 is two, and the two perforations 21 are arranged along the transverse direction X.

The drying device 30 is arranged in the first space A; in this embodiment, the drying device 30 mainly has a fan 31 and two heating pipes 32, through which the fan 31 causes air flow and passes through the heating pipe 32. After being heated by the heating tube 32, it is sent to the second space B.

The guide path 40 is arranged on the partition plate 20 and surrounds the perforation 21. The guide path 40 has a long side 41 and a short side 42 opposite to each other. The short side 42 is located on the long side 41 and one of the long sides 41. There is an acute angle 411 between the inner side surface 11 and the side of the long side 41 close to the short side 42 and the partition plate 20. The short side 42 is close to the side of the long side 41 and the partition plate 20. There is an obtuse angle 421 between them; in this embodiment, the two guide passages 40 have openings facing the two inner sides 11 respectively, and the heated air flow in the first space A will first flow toward the two inner sides 11, and then hit the After the inner side surface 11 bounces to the inner bottom surface 13, since the wind flow from the two perforations 21 bounces back to the inner bottom surface 13, the two wind flows will collide and jointly form an upward wind flow toward the partition plate 20, so that the Two circular heating air flows are formed in the two spaces B.

In this embodiment, an air suction port 22 is further provided between the two perforations 21 of the partition plate 20, and the air suction port 22 communicates with the first space A and the second space B, and the fan 31 corresponds to the suction The position of the tuyere 22 allows the gas in the second space B to be sucked into the first space A, so that the hot air sent by the two perforations 21 can flow back, and then the first space A can be sucked into the first space A from the suction port 22. The drying device 30 is heated and then sent out from the perforation 21.

Secondly, the drying device 30 further has two heating stations 33, the two heating stations 33 are arranged along the transverse direction X and assembled on the partition plate 20, and the two heating tubes 32 are respectively placed on the two heating stations 33 Above, the path of the wind flow is narrowed by the heating table 33, so that the wind flow flowing through the heating tube 32 is concentrated on the heating tube 32, which not only increases the heating speed when the wind flow passes, but also concentrates the wind flow through the heating tube 32 to make the wind flow uniform. heating.

Furthermore, the two heating stations 33 respectively have a drainage surface 331 inclined toward the fan 31, and the drainage surface 331 is sloped. When the fan 31 delivers air flow, the air flow can be guided to the heating tube 32 through the drainage surface 331. This prevents the formation of eddy currents between the heating table 33 and the fan 31, and the flow of wind is smoother.

The above is the structural configuration and connection relationship of the present invention in a preferred embodiment. The use of the present invention and the effects it can produce are as follows:

Please refer to FIG. 3, the second space B is for users to place dishes. Since the space in the cabinet 10 only has the first space A to place the drying device 30, the second space B can be used to place all the dishes, which greatly increases The number of dishes that can be accommodated.

After the drying device 30 is started, the fan 31 guides the air flow toward the two heating tubes 32, and the air flow close to the partition plate 20 can also flow toward the heating tube 32 through the guide surface 331 of the heating table 33, because the heating table 33 shrinks Due to the size of the passage of the air flow through the heating tube 32, the air flow is concentrated through the heating tube 32, and the temperature of the air flow can be quickly increased. The heated air flow passes through the heating tube 32 and is sent out from the two perforations 21 respectively.

In particular, through the two guide passages 40, the wind flow is guided by the long side 41 and the short side 42 of the guide passage 40 after passing through the perforation 21 to flow toward the two inner sides 11, and the wind flow hits the two inner sides. The inner side surface 11 rebounds and flows toward the inner bottom surface 13, and when two wind streams hit the inner bottom surface 13 and then rebound, the two wind streams meet together to form an upward wind stream flowing toward the fan 31.

Since the air flow has cooled down after flowing in the second space B, the cooled air flow is sucked by the fan 31, and the air flow is sucked into the first space A to re-heat, forming two whirling hot air circulations in the second space B.

The special feature of the present invention is that the two guide passages 40 guide the high-temperature air flow passing through the perforation 21 toward the two inner side surfaces 11, thereby preventing the air suction port 22 of the fan 31 from sucking the high-temperature air flow by mistake. Furthermore, since the air flow from the perforation 21 is directed directionally through the guide channel 40, the high-temperature air flow can reach the bottom of the casing 10 after only one rebound of the inner surface 11, so that the high-temperature air flow can reach the bottom of the casing 10 reliably. The inner bottom surface 13 heats up the second space B in an all-round way; and the two air streams collide and form an upward air stream flowing toward the fan 31, and combined with the suction of the fan 31, the air stream is drawn to the first space more quickly A, so that the temperature in the second space B can rise more quickly.

From the foregoing structure, it can be understood that the guidance of the two guide passages 40 can avoid the suction of the fan 31, so that the high-temperature air flow can flow directionally toward the inner bottom surface 13, which effectively quickly raises the inside of the second space B. After the two air streams pass through the inner side surface 11 and the inner bottom surface 13, the air stream will merge into an upward air stream flowing toward the fan 31, which is attracted by the fan 31 and returns to the first space A more quickly to reheat, not only the high temperature The air flow can effectively reach the bottom of the second space B, and the air flow can quickly flow back to the first space A for repeated heating, so that the temperature of the second space B can rise high enough to dry the dishes, and at the same time solve the problem of bacterial growth. In addition, a sterilization device is installed.
