Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to an exhaust device of a dishwasher and the dishwasher. Background Art

[0002] After years of development, the domestic dishwasher market has become increasingly mature. The existing household dishwashers all use essentially the same working principles. However, differences in domestic eating habits necessitate that dishwashers not only clean dishes but also keep them dry.

[0003] A dishwasher currently operates as follows: tap water, under pressure, enters the dishware container through the inlet valve after power is applied. A wash pump, connected to the bottom of the dishware container, pumps water into a spray arm connected to the container. The spray arm rotates continuously, spraying water onto the dishes. The water's impact forces stains onto the dishware, causing them to slide down into the container. The wastewater then passes through a filtration system and re-enters the wash spray arm. This cycle repeats repeatedly, rinsing away the stains and dispersing them into the water. The wastewater is then discharged outside the dishwasher through a drain pump, where it then enters the dishware container, washing, and draining the dishes repeatedly. After the wash cycle is complete, a supplementary hot air system blows hot air into the container to dry any remaining water.

[0004] In the prior art, for example, Chinese invention patent publication number CN106821265A discloses a respirator with a condensation drying function and a dishwasher using the same, comprising a box body and a cover body that interlock with each other. 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. A fan is provided at the end of the condensation channel. The respirator of the present invention can prevent siphoning and can also discharge and reuse the condensed water generated by the condensation of steam. The uncondensed steam is discharged through the fan, so that the dishes in the dishwasher can be quickly dried. The present invention also provides a dishwasher using a respirator with a condensation drying function, which can not only reduce the amount of steam discharged, but also reuse the condensed water of steam generated in the respirator, making the dishwasher more water-saving and energy-saving.

[0005] However, the above patent application still has the following problem: the hot air is discharged outwards by the pressure difference between the inside and outside of the container cavity. Therefore, after the hot air system has completed its work, the efficiency of discharging the hot air outwards is low. Utility Model Content

[0006] An object of the present application is to provide an exhaust device for a dishwasher and a dishwasher, which can improve the hot air exhaust efficiency.

[0008] Compared with the existing technology, the advantage of this application lies in the design of the fan. When the dishwasher needs to discharge hot air to the outside, the fan starts, extracts the gas in the shell assembly and discharges it, so that the shell assembly is in a negative pressure state. The hot air in the respirator naturally flows toward the negative pressure area, thereby improving the efficiency of hot air discharge.

[0009] In some embodiments of the present application, the air duct includes an air inlet channel and an air outlet channel, and the fan is located between the air inlet channel and the air outlet channel; one side of the air inlet channel is connected to the respirator, and the other side is connected to the fan; one side of the air outlet channel is connected to the air outlet of the fan, and the other side is connected to the outside world.

[0010] Furthermore, the opening of the air inlet channel faces downward; the opening of the air outlet channel faces obliquely upward.

[0011] Furthermore, a first baffle is provided on the air inlet channel, and the first baffle is arranged obliquely relative to the air inlet direction of the air inlet channel.

[0012] Furthermore, a second baffle is provided on the air outlet channel, and the second baffle is arranged obliquely relative to the air outlet direction of the air outlet channel.

[0013] Furthermore, a fan air inlet channel is provided between the air inlet channel and the air outlet channel, and the fan air inlet channel is connected to the air inlet channel and the air outlet channel respectively.

[0014] Furthermore, a first reinforcing rib is provided on the air inlet channel; and a second reinforcing rib is provided on the air outlet channel.

[0015] In some embodiments of the present application, the housing assembly includes a first housing and a second housing, and the first housing and the second housing are detachably connected; at least one side surface of the fan is located outside the housing assembly.

[0016] In some embodiments of the present application, the respirator is provided with a hot air outlet, and the shell assembly is provided with a limiting surface and a blocking block, and the blocking block is stuck into the respirator through the hot air outlet; when the shell assembly is connected to the respirator, the limiting surface abuts the outer surface of the respirator, and the blocking block abuts the inner surface of the respirator.

[0017] The utility model provides a dishwasher, which comprises the exhaust device of the dishwasher mentioned above. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] Example 1:

[0027] This embodiment provides an exhaust device for a dishwasher, such as Figure 1 、 Figure 2 As shown, the device comprises a respirator 1 and a housing assembly 2. The respirator 1 and housing assembly 2 are detachably connected, reducing the overall size and facilitating assembly and maintenance. An air duct is provided within the housing assembly 2, connecting the respirator 1 to the outside world. A fan 3 is provided in the air duct, and the air outlet of the fan 3 is connected to the outside world. The respirator 1 is provided with an air inlet that communicates with the dishwasher's inner tank 17.

[0028] The design of the fan 3 is that when the dishwasher needs to discharge hot air to the outside, the fan 3 starts, extracts the gas in the shell assembly 2 and discharges it, so that the shell assembly 2 is in a negative pressure state, and the hot air in the respirator 1 naturally flows toward the negative pressure area, thereby improving the efficiency of hot air discharge.

[0029] In order to ensure the reliability of the air duct, Figure 3As shown, the air duct includes an air inlet channel 4 and an air outlet channel 5, with the fan 3 located between the air inlet channel 4 and the air outlet channel 5. One side of the air inlet channel 4 is connected to the respirator 1, and the other side is connected to the fan 3. One side of the air outlet channel 5 is connected to the air outlet of the fan 3, and the other side is connected to the outside world. The fan 3 is arranged between the air inlet channel 4 and the air outlet channel 5, so that the gas extracted by the fan 3 first passes through the air inlet channel 4, facilitating the condensation and fall of water vapor in the air inlet channel 4. The gas is then blown out by the fan 3, facilitating the condensation and fall of water vapor in the air outlet channel 5, thereby reducing the residual water vapor in the blown gas.

[0030] In order to ensure reliable air intake, the opening of the air inlet channel 4 faces downward, and water vapor condenses in the air inlet channel 4 and falls downward, making it convenient for residual water to enter the respirator 1 for centralized treatment; the opening of the air outlet channel 5 faces obliquely upward, and water vapor condenses in the air outlet channel 5 and will not flow out from the opening of the air outlet channel 5.

[0031] In order to facilitate condensation of water vapor, Figure 4 As shown, the air inlet channel 4 is provided with a first baffle 6, which is arranged obliquely relative to the air inlet direction of the air inlet channel 4; the first baffle 6 is provided on both sides of the air inlet channel 4. The design of the first baffle 6 can cause the airflow entering the air inlet channel 4 to collide with it, facilitating condensation of water vapor on the first baffle 6.

[0032] To facilitate condensation of water vapor, the air outlet channel 5 is provided with a second baffle 7, which is arranged obliquely relative to the air outlet direction of the air outlet channel 5 and is provided on both sides of the air outlet channel 5. The design of the second baffle 7 allows the airflow entering the air outlet channel 5 to collide with it, facilitating condensation of water vapor on the second baffle 7.

[0033] In order to ensure the reliability of the air duct, Figure 5 、 Figure 6 As shown, a fan air inlet channel 8 is provided between the air inlet channel 4 and the air outlet channel 5, and the fan air inlet channel 8 is connected to the air inlet channel 4 and the air outlet channel 5 respectively. The design of the fan air inlet channel 8 can facilitate the air intake of the fan 3. At the same time, when the fan 3 is damaged, the fan air inlet channel 8 can also connect the air inlet channel 4 and the air outlet channel 5 to facilitate the discharge of gas.

[0034] To enhance structural strength, the air inlet passage 4 is provided with first reinforcing ribs 9 arranged in a grid pattern, thereby strengthening the structural strength of the air inlet passage 4. The air outlet passage 5 is provided with second reinforcing ribs 10 arranged in a grid pattern, thereby strengthening the structural strength of the air outlet passage 5. The first and second reinforcing ribs 9, 10 enhance the structural strength of the entire housing assembly 2, enabling the housing assembly 2 to support the installation of the fan 3.

[0035] To ensure reliability, the housing assembly 2 includes a first housing 11 and a second housing 12. The first and second housings 11, 12 are detachably connected, facilitating installation and maintenance of the fan 3 within. At least one side of the fan 3 is positioned outside the housing assembly 2, facilitating heat dissipation. In this embodiment, a notch 16 is defined in the first housing 11, through which one side of the fan 3 extends outside the first housing 11. Both the first and second housings 11, 12 are provided with a first baffle 6, a second baffle 7, a first reinforcing rib 9, and a second reinforcing rib 10.

[0036] To ensure reliable installation of the respirator 1 and the housing assembly 2, the respirator 1 is provided with a hot air outlet 13, and the housing assembly 2 is provided with a limiting surface 14 and a clamping block 15. The clamping block 15 is inserted into the respirator 1 through the hot air outlet 13. When the housing assembly 2 and the respirator 1 are connected, the limiting surface 14 abuts the outer surface of the respirator 1, and the clamping block 15 abuts the inner surface of the respirator 1. The housing assembly 2 and the respirator 1 are clamped together, making installation easy. The limiting surface 14 is used to limit the position, preventing the housing assembly 2 from entering the respirator 1 too deeply, so that the clamping block 15 abuts the inner surface of the respirator 1. The clamping block 15 cooperates with the limiting surface 14 to secure the housing assembly 2 to the respirator 1.
