Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a condensing respirator capable of realizing rapid heat exchange. Background Art

[0002] A sink dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, and forks. It can be divided into two categories according to its structure: box type and conveyor type. Conveyor type sink dishwashers are mainly used in large catering places such as restaurants, hotels, and canteens of government agencies, thereby reducing the labor intensity of cooks, improving work efficiency, and improving cleanliness and hygiene. With the development of dishwasher technology, the functions of dishwashers are gradually increasing. From the original one washing function to the current multiple washing functions, dishwashers can wash more types of tableware and various surface attachments. However, the overall volume of the dishwasher has not changed much. In order to make the dishwasher have more functions within a certain space range, this requires the dishwasher to integrate more functions into the original structure. The respirator used in the dishwasher has a good condensation effect, but the condensation efficiency is low.

[0003] Chinese patent application number CN201120210340.9 discloses a top pipe condensing device for a dishwasher, comprising an inner tank, a connecting pipe, a breather regeneration water cavity and a condensing device, wherein the condensing device is installed at the rear end top of the inner tank of the dishwasher, the breather regeneration water cavity is installed on the outer side wall of the inner tank, and one end of the connecting pipe is connected to the water pipe interface of the breather regeneration water cavity. It is characterized in that the condensing device comprises a cross-piece, a float, a cross-piece body and a locking nut, wherein the float is inserted into the float cavity of the cross-piece body, the cross-piece upper piece and the cross-piece body are sealed by welding to form a complete hollow cavity and encapsulate the float therein, the inner tank connecting port on the cross-piece body is installed on the inner tank opening at the top of the inner tank through a locking nut, and the other end of the connecting pipe is connected to the water pipe interface of the cross-piece body.

[0004] Chinese patent application number CN201710129751.7 discloses a high-efficiency dishwasher, including an electrical box and a body. The electrical box is arranged above the body, and a microprocessor is arranged inside the electrical box. A stainless steel exhaust pipe is arranged on the top of the body. Guide rails, a bowl basket and a liquid storage tank are arranged inside the body. The bowl basket is fixedly connected to the body, and a high liquid level sensor and a low liquid level sensor are provided on the liquid storage tank. A delivery pipe is connected to the liquid storage tank, and the delivery pipe is slidably connected to the guide rail. A nozzle is installed at the other end of the delivery pipe. A storage box and a water inlet pipe are arranged on the right side of the body. The storage box is connected to the liquid inlet pipe, one end of the liquid inlet pipe is connected to the liquid storage tank, and a water inlet switch valve is provided on the water inlet pipe.

[0005] Although the above-mentioned prior art discloses certain technical solutions of the respirator and the condenser, it still has disadvantages such as low condensation efficiency, long working time, and high energy consumption when in use.

[0006] Therefore, it is necessary to improve the shortcomings and defects of the existing technology and provide a condensation structure that can achieve rapid heat exchange. This structure can significantly improve the condensation effect of the exhaust duct of the respirator. The respirator uses a blower to quickly remove the high-temperature gas inside the dishwasher. The unique grid-like condensation structure is placed on both sides of the air duct to connect the exhaust duct with the outside world. The metal grid-like condensation structure has efficient heat transfer capabilities. The design of internal and external connection allows the outside air to exchange heat with the high-temperature steam in the air duct. The vertically designed grid-like heat transfer structure can take away heat to the maximum extent without affecting the gas flow, providing a more reasonable solution for the dishwasher respirator with a high-temperature gas condensation function, which can bring a better experience to users.

[0007] In view of this, the present invention is proposed. Summary of the Invention

[0070] like Figures 1 to 3As shown, this embodiment is a further limitation of the above-mentioned embodiment 1. The second condensation section 8 described in this embodiment has a shorter length along the air duct 5 than the first condensation section 7. Specifically, a mounting port 9 and an exhaust port 4 are provided between the air duct 5 of the respirator upper cover 1. The second condensation section 8 is inserted into the mounting port 9. There are several raised positioning columns 11 around the side wall of the mounting port 9 for inserting into the through hole of the first condensation section 7. When the installation is completed, the plastic of the positioning columns 11 can be melted by heating or ultrasonic welding to achieve the function of fixing the condensation structure 6. The lowest point of the opening is higher than the highest point of the high drainage structure of the respirator, that is, the highest point of the drainage port, and there is no need to install a sealing strip between the grid-like condensation structures 6.

[0071] Example 3

[0072] like Figures 1 to 3 As shown, this embodiment is a further limitation of the above-mentioned embodiment 2. The condensation structure 6 described in this embodiment is composed of a planar first condensation part 7 and several second condensation parts 8 of longitudinal flat plate structure. The structure can be integrally cast, machined or welded. Several positioning columns 11 are set at the installation port 9 on the respirator cover 1. The positioning columns 11 can be inserted into the through holes of the first condensation part 7. The second condensation part 8 is slightly smaller than the installation port 9 and is close in size to the plane between the exhaust baffle and the exhaust port 4. Its function is to be inserted into the opening. Several longitudinal flat plates form several longitudinal channels, allowing high-temperature steam to flow through the channels, and generate heat exchange with the grid-like condensation structure 6 during circulation; the first condensation part 7 is obviously larger than the opening, and the function of the plane is to provide a sufficiently large heat dissipation area as much as possible and cooperate with the opening; the through holes on the first condensation part 7 are used to cooperate with the positioning columns 11 of the vertical edges of the opening to play the role of positioning and plastic melting and welding.

[0073] Example 4

There are several notches on both sides of the first condensation part 7, which are used to cooperate and connect with the buckles 12 corresponding to the outer walls on both sides of the mounting port 9 of the air duct 5.

[0077] The size difference between the first condensation section 7 and the second condensation section 8 described in this embodiment is relatively small. The second condensation section 8 is slightly smaller than the size of the installation opening 9 and can be inserted into the installation opening 9. Several longitudinally arranged flat plates form several longitudinal channels, allowing high-temperature steam to flow through the channels, and generate heat exchange with the grid-like condensation structure 6 during circulation; the first condensation section 7 is slightly larger than the size of the installation opening 9, cooperates with the vertical edge of the installation opening 9, and is connected to the buckle 12 to provide a sufficiently large heat dissipation area. The through hole on the first condensation section 7 cooperates with the positioning column 11 on the vertical edge of the installation opening 9 to play a role in positioning and plastic melting and welding.
