Description

Technical Field

[0001] The present invention belongs to the field of dishwashers, and in particular relates to a respirator with a high-temperature gas condensation reflux structure. Background Art

[0002] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, and forks. A commonly used appliance today is a cabinet-type device similar to a disinfection cabinet. Used bowls, plates, and other tableware are placed in the cabinet's compartments and cleaned using a water spray mechanism and ultrasonic generator. The dishwasher's final step is drying, using direct heat from heating tubes or residual heat to evaporate residual water on the surface of the dishes inside the machine. This moisture is then transported to the outside of the machine through a hole connecting the machine to the outside world, achieving the desired drying effect. With the development of dishwasher technology, the functionality of dishwashers has gradually increased, from having only one washing function to multiple washing functions. Dishwashers can now clean a wider variety of tableware and various surface attachments. However, the overall size of the dishwasher has not changed significantly. In order to accommodate more functions within a certain space, dishwashers must integrate more functions into their original structure.

[0003] The breathers used in existing dishwashers generally have the following functions: first, they maintain the pressure balance inside and outside the dishwasher. A hole is opened in the side wall of the dishwasher's inner cavity and connected to the breather, which balances the internal and external pressures through gas flow; second, they have a built-in flow meter for water inlet; third, they have an anti-siphoning function; and fourth, they provide the required water for the water softener.

[0004] Chinese patent application number CN 201710089158.4 discloses a respirator with a condensation drying function, comprising a box body and a cover body that are interlocked. The box body is provided with a steam inlet connected to the inner tank of the dishwasher and a steam outlet connected to the outside. The box body is provided with a water diversion port and a drain port. A water storage chamber is formed in the box body between the water diversion port and the drain port. A condensation channel is provided in the box body between the steam inlet and the steam outlet. The condensation channel is provided in the water storage chamber. A condensation water discharge port is provided below the condensation channel, and a fan is provided at the end of the condensation channel.

[0005] Chinese patent application number CN 201620130398.5 discloses a breather for a dishwasher. The breather includes a three-way pipe, one of which is a water inlet, another is a water outlet, and the third is an air passage. A ventilation hole is provided inside the air passage, and a diaphragm is fixed on the outer wall of the hole.

[0006] The breather and fan are essential components of a dishwasher. Currently, the existing technology mostly installs the breather and fan duct as separate components, resulting in a complex structure and time-consuming installation. Although the above two breathers solve certain existing problems, the connection between the fan and the duct in the existing technology is a rigid connection. The vibration generated by the fan will be transmitted through this connection and amplified, thereby causing damage to the breather and the dishwasher. In view of the above shortcomings, it is necessary to propose a breather that adds an exhaust function to the existing breather to quickly dry the inner cavity of the dishwasher; adds a steam condensation structure to prevent water vapor from entering the cabinet and prevents foam generated by detergent from entering the blower through the duct; and adds a high drainage function.

[0007] In view of this, the present invention proposes a new type of respirator with a blower and a high-temperature steam condensation and reflux structure. The respirator has its own blower, which can quickly remove the high-temperature steam inside the dishwasher. The unique condensation structure in the exhaust duct can quickly cool the high-temperature steam and reflux it into the dishwasher. This structure can provide a reasonable solution for the removal of high-temperature gas after the dishwasher adds a high-temperature steam function, and at the same time increase the anti-siphon function of the respirator, ensuring the internal and external pressure balance of the dishwasher cavity, which can bring a better experience to users. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a respirator with a high-temperature gas condensation reflux structure that can overcome the above problems or at least partially solve the above problems.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a respirator with a high-temperature gas condensation reflux structure, including a respirator lower cover and a respirator upper cover cooperating with the respirator lower cover; a ventilation unit, including an exhaust port arranged on the respirator lower cover and an air duct connected to the exhaust port, and a steam condensation structure is provided inside the air duct.

[0010] Among them, the ventilation unit also includes an exhaust baffle arranged in the air duct near the exhaust port side. The air duct baffle connects the air duct and the exhaust port in a one-way manner. The setting of the air duct baffle can ensure that during the washing process, due to the gravity in a closed state, the overflow of water and gas during the washing process can be avoided.

[0011] In addition, the steam condensation structure is arranged between the exhaust baffle and the exhaust port in the air duct. This structure can quickly reduce the temperature of water vapor, and the condensed water droplets will adhere to the steam condensation structure.

[0012] Furthermore, the steam condensation structure is at least one sheet structure arranged on the inner side of the air duct and inclined toward the exhaust port. The inclined surface arrangement of the structure is conducive to the condensed water droplets flowing back to the bottom of the dishwasher cavity through the exhaust port.

[0013] At the same time, the ventilation unit also includes a fan installed on the upper cover of the respirator and a fixing unit for fixing the fan.

[0014] Furthermore, a vibration damping unit is provided on the contact surface between the fixing unit and the fan. The vibration damping unit wraps the fan and is suspended on the fixing unit, which can reduce the vibration generated during the operation of the fan, avoid the vibration amplification caused by traditional hard connection, and reduce the damage of the fan vibration to the respirator.

[0015] In addition, the lower cover of the breather is provided with a water outlet, a first air hole and a second air hole. The water outlet, the first air hole and the second air hole are interconnected in the cavity formed by the lower cover of the breather and the upper cover of the breather. This setting enables the breather to have an anti-siphon function, which can ensure that the inner cavity of the dishwasher is connected to the external atmospheric environment, thereby ensuring the internal and external pressure balance of the inner cavity of the dishwasher.

[0016] In addition, a high-level drainage structure is also provided on the outside of the lower cover of the respirator. The high-level drainage structure forms a height difference between the highest point of the drain pipe and the water level in the inner cavity of the dishwasher. The structure is located in the upper middle part of the respirator and is used to hang a fixed drain pipe so that the highest point of the drain pipe forms a height difference with the inner cavity of the dishwasher. When the water level exceeds this height, the water in the inner cavity of the dishwasher will automatically be discharged under its own weight. When the water level is lower than this height, the water in the inner cavity of the dishwasher will not be discharged by its own weight, but can only be discharged by the drainage pump.

[0017] Furthermore, the respirator is also provided with a water inlet, a flow meter, a first water inlet channel and a second water inlet channel. After passing through the water inlet and the flow meter, water flows into the dishwasher tank and the water softener through the first water inlet channel and the second water inlet channel respectively.

[0018] Furthermore, the air duct is an inverted U-shaped structure, which, when used in conjunction with the steam condensation structure, can quickly reduce the temperature of water vapor. The condensed water droplets will adhere to the steam condensation structure. The inclined arrangement of the structure is conducive to the condensed water droplets to flow back to the bottom of the dishwasher cavity through the exhaust port.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] 1. The respirator and ventilation unit are designed as one piece, making the overall integration performance higher and easier to install;

[0021] 2. The air duct baffle is set to ensure that during the washing process, the air duct is in a closed state due to gravity, which can prevent the overflow of water and gas during the washing process;

[0022] 3. A vibration reduction unit is set between the fan and the fixed unit to prevent the vibration generated during the operation of the fan from being transmitted through this connection and then amplified, causing damage to the respirator;

[0023] 4. Added steam condensation structure to prevent water vapor from entering the cabinet and prevent the foam generated by detergent from entering the blower through the air duct;

[0024] 5. The high drainage function is added, and the function of the dishwasher can be expanded according to different requirements. It has a simple structure, saves space, and has a relatively low cost.

[0025] 6 The present invention integrates the functions of breather anti-siphon, water inlet measurement, connection with water softener, dishwasher cavity water inlet, dishwasher cavity drying, anti-high temperature gas condensation outside the dishwasher, and high drainage, thus achieving a high degree of concentration of the dishwasher breather functions.

[0034] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] like Figures 1 to 4 As shown, the present invention is a respirator with a high-temperature gas condensation reflux structure, including a respirator lower cover 4, a respirator upper cover 3 cooperating with the respirator lower cover 4, and the respirator upper cover 3 and the respirator lower cover 4 are bonded together by a plastic hot plate welding process; the ventilation unit 5 includes an exhaust port 6 arranged on the respirator lower cover 4 and an air duct 7 connected to the exhaust port 6, and a steam condensation structure 8 is provided inside the air duct 7.

[0039] Among them, the ventilation unit 5 also includes an exhaust baffle 9 arranged in the air duct 7 near the exhaust port 6. The air duct baffle 9 unidirectionally connects the air duct 7 and the exhaust port 6. The setting of the air duct baffle 9 can ensure that during the washing process, due to the gravity in a closed state, the overflow of water and gas during the washing process can be avoided.

[0040] In addition, the steam condensation structure 8 is arranged between the exhaust baffle 9 and the exhaust port 6 in the air duct 7. This structure can quickly reduce the temperature of water vapor, and the condensed water droplets will adhere to the steam condensation structure 8.

[0041] Furthermore, the steam condensation structure 8 is at least one sheet structure arranged on the inner side of the air duct 7 and inclined toward the exhaust port 6. The inclined arrangement of the structure is conducive to the condensed water droplets flowing back to the bottom of the dishwasher cavity through the exhaust port 6.

[0042] Meanwhile, the ventilation unit 5 further includes a fan 10 mounted on the respirator upper cover 3 and a fixing unit 11 for fixing the fan 10 .

[0043] Furthermore, the vibration damping unit 12 wraps around the fan 10 and is embedded in the concave cavity formed by the upper cover 3 and the lower cover 4 of the respirator. Finally, the vibration damping unit 12 is suspended on the fixing unit 11 on the upper cover 3 of the respirator, thereby preventing the fan 10 from directly contacting the upper cover 3, the lower cover 4, and the fixing unit 11, thereby preventing the formation of a hard connection. This in turn avoids the vibration amplification and vibration damage problems caused by the hard connection. The respirator of the present invention has an exhaust function and can quickly dry the inner cavity of the dishwasher. The exhaust port 6 is located near the bottom of the dishwasher tank 1, which is conducive to the effective removal of gas from the dishwasher tank 1. When the dishwasher tank 1 needs to remove water vapor or perform a drying process, the fan 10 is started to exhaust the air duct 7. During the exhaust process, the baffle of the air duct 7 will form an opening upward, so that the air duct 7 is connected to the dishwasher tank 1 through the exhaust port 6.

[0044] In addition, the respirator lower cover 4 is provided with a water outlet 13, a first air hole 14 and a second air hole 15. The water outlet 13, the first air hole 14 and the second air hole 15 are interconnected in the cavity formed by the respirator lower cover 4 and the respirator upper cover 3. This setting enables the respirator to have an anti-siphon function, which can ensure that the inner cavity of the dishwasher is connected to the external atmospheric environment, thereby ensuring the internal and external pressure balance of the dishwasher cavity. In addition, the reinforcing rib next to the water outlet 13 is higher than the center of the water outlet 13. Its purpose is to ensure that the water in the first water inlet channel 19 will not enter the air hole channel in the process of passing through the water outlet 13, thereby playing a water-blocking role.

[0045] In addition, a high-level drainage structure 16 is further provided on the outside of the respirator lower cover 4. The high-level drainage structure 16 forms a height difference between the highest point of the drain pipe and the water level in the dishwasher cavity. The structure is located in the upper middle part of the respirator and is used to hang a fixed drain pipe so that the highest point of the drain pipe forms a height difference with the dishwasher cavity. When the water level exceeds this height, the water in the dishwasher cavity will automatically be discharged under its own weight. When the water level is lower than this height, the water in the dishwasher cavity will not be discharged by its own weight, but can only be discharged by a drainage pump. This height can provide enough water for the dishwasher to wash tableware, and can also provide enough soaking water for the sink-type dishwasher to wash vegetables and fruits, and can also replace the overflow hole of the sink dishwasher.

[0046] Furthermore, the respirator is also provided with a water inlet 17, a flow meter 18, a first water inlet channel 19 and a second water inlet channel 20. After passing through the water inlet 17 and the flow meter 18, the water flows into the dishwasher inner tank 1 and the water softener through the first water inlet channel 19 and the second water inlet channel 20 respectively. This structure can provide washing water for the dishwasher and water for the water softener. Its working process is as follows: the water inlet 17 is connected to the water inlet solenoid valve on the dishwasher through a rubber water pipe, and the water softener interface 21 is connected to the water softener through a hose or its own water outlet structure; tap water enters the water inlet 17 through the rubber pipe of the water inlet solenoid valve, passes through the flow meter 18, and then flows into the first water inlet channel 19 and the second water inlet channel 20 respectively through the water inlet channel. The water in the first water inlet channel 19 enters the inner cavity of the dishwasher from the water inlet 17, and the water in the second water inlet channel 20 enters the water softener through the water softener interface 21.

[0047] Furthermore, the air duct 7 is an inverted U-shaped structure, which is used in conjunction with the steam condensation structure 8 to quickly reduce the temperature of water vapor. The condensed water droplets will adhere to the steam condensation structure 8. The inclined surface of the structure is conducive to the condensed water droplets flowing back to the bottom of the dishwasher cavity through the exhaust port 6. The air duct 7 is an inverted "U"-shaped structure. The air duct 7 can allow the gas to enter the air duct 7 from the lowest point, flow upward in the air duct 7, and then flow downward. This can prevent water from flowing out of the dishwasher through the air duct 7 when the dishwasher is washing. At the same time, in the air duct 7, when the gas moves from bottom to top (or the air duct 7 is close to the exhaust port 6), several iron plates are installed below the highest point of the air duct 7, and an air duct 7 is formed between the iron plates in the direction of gas flow.

[0048] In general, the respirator with a high-temperature gas condensation reflux structure of the present invention mainly includes a fan 10, a flow meter 18, an air duct 7 (with a steam condensation reflux structure), a water inlet channel, a water inlet 17, a water outlet, a water softener interface 21, and two air holes.

[0049] The present invention provides a respirator with a high-temperature gas condensation reflux structure. In addition to the functions of the original respirator, an exhaust function is added, which can quickly dry the inner cavity of the dishwasher. A steam condensation structure 8 is added to prevent water vapor from entering the cabinet and prevent foam generated by the detergent from entering the blower 10 through the air duct 7. A high drainage function is added, and the function of the dishwasher can be expanded according to different requirements. The structure is simple, space-saving, and the cost is relatively low.

[0050] Example 1

[0051] like Figures 1 to 4As shown, the respirator with a high-temperature gas condensation reflux structure described in this embodiment includes a respirator lower cover 4, a respirator upper cover 3 cooperating with the respirator lower cover 4; a ventilation unit 5, including an exhaust port 6 arranged on the respirator lower cover 4 and an air duct 7 connected to the exhaust port 6, and a steam condensation structure 8 is provided inside the air duct 7.

[0052] Among them, the ventilation unit 5 also includes an exhaust baffle 9 arranged in the air duct 7 near the exhaust port 6. The air duct 7 baffle connects the air duct 7 and the exhaust port 6 in a one-way manner. The setting of the air duct 7 baffle can ensure that during the washing process, due to the gravity in a closed state, the overflow of water and gas during the washing process can be avoided.

[0053] In addition, the steam condensation structure 8 is arranged between the exhaust baffle 9 and the exhaust port 6 in the air duct 7. This structure can quickly reduce the temperature of water vapor, and the condensed water droplets will adhere to the steam condensation structure 8.

[0054] Furthermore, the steam condensation structure 8 is at least one sheet structure arranged on the inner side of the air duct 7 and inclined toward the exhaust port 6. The inclined arrangement of the structure is conducive to the condensed water droplets flowing back to the bottom of the dishwasher cavity through the exhaust port 6.

[0055] Meanwhile, the ventilation unit 5 further includes a fan 10 mounted on the respirator upper cover 3 and a fixing unit 11 for fixing the fan 10 .

[0056] Furthermore, a vibration damping unit 12 is provided on the contact surface between the fixing unit 11 and the fan 10. The vibration damping unit wraps the fan 10 and is suspended on the fixing unit 11, which can reduce the vibration generated during the operation of the fan 10, avoid the vibration amplification caused by traditional hard connection, and reduce the damage to the respirator caused by the vibration of the fan 10.

[0057] In addition, the breather lower cover 4 is provided with a water outlet 13, a first air hole 14 and a second air hole 15. The water outlet 13, the first air hole 14 and the second air hole 15 are interconnected in the cavity formed by the breather lower cover 4 and the breather upper cover 3. This arrangement enables the breather to have an anti-siphon function, which can ensure that the inner cavity of the dishwasher is connected to the external atmospheric environment, thereby ensuring the internal and external pressure balance of the dishwasher cavity.

[0058] In addition, a high-level drainage structure 16 is provided on the outside of the respirator lower cover 4. The high-level drainage structure 16 forms a height difference between the highest point of the drain pipe and the water level in the dishwasher cavity. The structure is located in the upper middle part of the respirator and is used to hang and fix the drain pipe so that the highest point of the drain pipe forms a height difference with the dishwasher cavity. When the water level exceeds this height, the water in the dishwasher cavity will automatically be discharged under its own weight. When the water level is lower than this height, the water in the dishwasher cavity will not be discharged by its own weight, but can only be discharged by the drainage pump.

[0059] Furthermore, the respirator is also provided with a water inlet 17, a flow meter 18, a first water inlet channel 19 and a second water inlet channel 20. After passing through the water inlet 17 and the flow meter 18, the water flows into the dishwasher inner tank 1 and the water softener through the first water inlet channel 19 and the second water inlet channel 20 respectively.

[0060] Furthermore, the air duct 7 is an inverted U-shaped structure, which is used in conjunction with the steam condensation structure 8 to quickly reduce the temperature of water vapor. The condensed water droplets will adhere to the steam condensation structure 8. The inclined arrangement of the structure is conducive to the condensed water droplets to flow back to the bottom of the dishwasher cavity through the exhaust port 6.

[0061] Example 2

[0062] This embodiment is a further limitation of the above-mentioned embodiment 1. The breather described in this embodiment is installed on the side wall 2 of the sink body of the dishwasher, and the water outlet and the exhaust port 6 are connected to the inner tank 1 of the dishwasher. The breather structure can provide washing water for the dishwasher and water for the water softener. Its working process is as follows: the water inlet 17 is connected to the water inlet solenoid valve on the dishwasher through a rubber water pipe, and the water softener interface 21 is connected to the water softener through a hose or its own water outlet structure; tap water enters the water inlet 17 through the rubber pipe of the water inlet solenoid valve, passes through the flow meter 18, and then flows into the first water inlet channel 19 and the second water inlet channel 20 respectively through the water inlet channel. The water in the first water inlet channel 19 enters the inner cavity of the dishwasher from the water inlet 17, and the water in the second water inlet channel 20 enters the water softener through the water softener interface 21.
