Description

Technical Field

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

[0002] During the dishwashing process, the dishwasher usually heats and pressurizes the water in the dishwasher tank through a washing pump, and uses the high temperature and high pressure of the water flow to rinse and spray the dishes. During this process, a large amount of hot and humid gas will be generated, which will cause the pressure in the dishwasher tank to be too high. Therefore, the high temperature and high pressure hot and humid gas needs to be discharged to the outside of the dishwasher through an exhaust device to balance the pressure inside the dishwasher tank and the outside world.

[0003] Existing exhaust devices typically have an air inlet connected to the inner liner, an exhaust passage, and an exhaust port connected to the outside world. To reduce the water content of the gas when it is discharged from the exhaust port, multiple baffles are usually arranged in a staggered manner in the exhaust passage, and two adjacent baffles are spaced apart in the vertical direction to form an air passage for the gas to flow through. This can extend the flow path of the humid and hot air and improve the condensation effect of the humid and hot air. However, in the above structure, the multiple baffles will block the flow of the humid and hot gas in the vertical direction, resulting in the humid and hot gas only being able to flow horizontally along the air passage between adjacent baffles, causing the humid and hot gas to flow slowly. In addition, when the high-temperature and high-pressure humid and hot gas flows from the air inlet into the exhaust passage and directly hits the baffle, it is also easy for the humid and hot gas to directly flow back due to the large-area collision. Therefore, it is not conducive to the discharge of the humid and hot gas in the inner liner, resulting in a poor exhaust effect of the exhaust device. Utility Model Content

[0042] Reference Figures 1 to 4One embodiment of the present invention provides an exhaust device, which includes a shell 100, a first spoiler structure, and a second spoiler structure. The shell 100 has an exhaust channel, and the side wall of the shell 100 is provided with an air inlet 101 and an exhaust port 102 connected to the exhaust channel, and the exhaust port 102 is located below the air inlet 101; the exhaust channel includes a first channel 200 and a second channel 300, and the first channel 200 has a first guide portion 210 and a second guide portion 220, the first guide portion 210 is connected to the air inlet 101 and is arranged from bottom to top to the left relative to the air inlet 101, the second guide portion 220 is connected to the upper end of the first guide portion 210 and is arranged from bottom to top to the right relative to the first guide portion 210; the second channel 300 is located at the air inlet 101 and is connected to the exhaust port 102, and the upper end of the second channel 300 is connected to the upper end of the second guide portion 220; the first spoiler structure is provided in the first channel 200, and the first spoiler structure includes at least two first spoiler columns 240 arranged at intervals, and the first spoiler columns 240 are extended along the thickness direction of the first channel 200; the second spoiler structure is provided in the second channel 300, and the second spoiler structure includes at least two second spoiler columns 310 arranged at intervals, and the second spoiler columns 310 are extended along the thickness direction of the second channel 300; wherein, the length of the first spoiler column 240 is greater than the length of the second spoiler column 310.

[0043] By adopting the exhaust device of the embodiment of the present invention, the shell 100 can be placed on the outer wall of the inner tank of the dishwasher and the air inlet 101 can be connected to the inside of the inner tank. The hot and humid gas formed in the inner tank can flow into the exhaust channel of the shell 100 through the air inlet 101, and flow through the first channel 200 and the second channel 300 in sequence, and finally be discharged from the exhaust port 102. During this process, since the first channel 200 includes the first guide portion 210 and the second guide portion 220, both the first guide portion 210 and the second guide portion 220 can guide the gas to flow rapidly and reduce the risk of gas backflow. Specifically, the first guide portion 210 is connected to the air inlet 101 and is arranged from bottom to top to the left relative to the air inlet 101. This can guide the hot and humid gas at the air inlet 101 to flow upward from right to left along the first guide portion 210. Since hot and humid gas has an upward tendency to flow, when the first guide portion 210 guides the hot and humid gas to flow upward, the hot and humid gas is not likely to flow backward. Since the second guide portion 220 is connected to the upper end of the first guide portion 210 and is arranged from bottom to top to the right relative to the first guide portion 210, the second guide portion 220 is located above the air inlet 101 and can guide the hot and humid gas in the first guide portion 210 to flow upward from left to right, without causing backflow. In addition, when the gas flows from the second guide portion 220 to the second channel 300, it can flow downward along the second channel 300 to the exhaust port 102. Since the second channel 300 is located on the right side of the air inlet 101 and the upper end of the second channel 300 is connected to the upper end of the second guide portion 220, that is, the second channel 300 and the second guide portion 220 are shaped like an inverted V. Therefore, even if the gas entering the second channel 300 flows back upward due to the obstruction of the second spoiler structure, it is not easy to flow back downward to the second guide portion 220 again, which is conducive to the discharge of gas.

[0044] In addition, by providing the first spoiler structure and the second spoiler structure, the hot and humid gas flowing from the air inlet 101 into the first channel 200 can fully contact the first spoiler column 240, and the hot and humid gas flowing from the first channel 200 to the second channel 300 can fully contact the second spoiler column 310. Since the gas temperature in the first channel 200 is usually higher than the gas temperature in the second channel 300, the spoiler effect of the second spoiler column 310 on the gas can be smaller than the spoiler effect of the first spoiler column 240 on the gas, so that the gas can flow quickly to the exhaust port 102 when flowing from the first channel 200 into the second channel 300, which is conducive to the rapid discharge of the gas. Compared with the existing technology that adopts a staggered arrangement of multiple baffles, the first spoiler structure and the second spoiler structure of the embodiment of the utility model both adopt a spoiler column structure, which not only increases the contact area between the gas and the spoiler structure, but also reduces the obstruction of the spoiler structure to the gas, so that the gas can pass smoothly through the gaps between the spoiler columns, thereby condensing the hot and humid air while facilitating the rapid discharge of the hot and humid air.

[0045] Reference Figures 1 to 4 In some embodiments, the first channel 200 further includes an arc-shaped connecting portion 230 connected between the first guide portion 210 and the second guide portion 220, and a first spoiler structure is provided on the arc-shaped connecting portion 230; and further includes a third spoiler structure provided on the second guide portion 220, the third spoiler structure including at least two third spoiler columns 250 arranged at intervals, the third spoiler columns 250 being provided on an inner wall on one side of the first channel 200 and extending along the thickness direction of the first channel 200, and the length of the first spoiler column 240 being greater than the length of the third spoiler column 250.

[0046] By adopting the above structure, the provision of the arcuate portion can guide the gas in the first guide portion 210 to the second guide portion 220, allowing the gas to be quickly discharged along the exhaust channel. By providing the first spoiler structure on the arcuate connecting portion 230 and the third spoiler structure on the second guide portion 220, and by ensuring that the length of the first spoiler column 240 is greater than the length of the third spoiler column 250, the spoiler effect of the third spoiler column 250 on the gas can be made smaller than the spoiler effect of the first spoiler column 240 on the gas. As a result, the gas can be fully contacted with the first spoiler structure at the arcuate connecting portion 230, effectively reducing the temperature of the gas. When the gas flows from the arcuate connecting portion 230 into the second guide portion 220, it can quickly flow to the second channel 300, thereby facilitating the rapid discharge of the gas.

[0047] It is understandable that the first spoiler structure is provided on the arc-shaped connecting portion 230, which is only for Figures 1 to 4As an example, the first spoiler structure can be provided on the first guide portion 210 or both the first guide portion 210 and the arc-shaped connecting portion 230 in addition to being provided on the arc-shaped connecting portion 230. The present invention does not make any specific limitation on this. Similarly, the third spoiler structure provided on the second guide portion 220 is only for Figures 1 to 4 As an exemplary illustration, the third spoiler structure can be provided on the second guide portion 220 as well as on the arcuate connecting portion 230 or on both the arcuate connecting portion 230 and the second guide portion 220, and the present invention does not make any specific limitation on this.

[0048] Reference Figures 1 to 12 In some embodiments, the shell 100 includes a front shell 110 and a rear shell 120 arranged opposite to each other in the front-to-back direction, the front shell 110 and the rear shell 120 enclose each other to form an exhaust channel and an exhaust port 102, the air inlet 101 is opened on the side wall of the rear shell 120, and the front shell 110 and the rear shell 120 are welded together; the number of first spoiler structures is two groups, wherein the first spoiler columns 240 of one group of the first spoiler structures are arranged on the front shell 110 and extend toward the rear shell 120, and the first spoiler columns 240 of the other group of the first spoiler structures are arranged on the rear shell 120 and extend toward the front shell 110; the number of second spoiler structures is two groups, wherein the second spoiler columns 310 of one group of the second spoiler structures are arranged on the front shell 110 and extend toward the rear shell 120, and the second spoiler columns 310 of the other group of the second spoiler structures are arranged on the rear shell 120 and extend toward the front shell 110.

[0049] By adopting the above structure, the housing 100 is divided into a front housing 110 and a rear housing 120. The welding connection between the front housing 110 and the rear housing 120 can ensure the sealing of the exhaust duct and reduce the risk of air leakage in the exhaust device. During installation, the rear housing 120 can be attached to the outer wall of the dishwasher's inner tank, and the air inlet 101 is connected to the interior of the tank. By providing two sets of first spoiler structures and separately arranging the two sets of first spoiler structures in the front housing 110 and the rear housing 120, it is beneficial to improve the exhaust device's condensation effect on gas. By providing two sets of second spoiler structures and separately arranging the two sets of second spoiler structures in the front housing 110 and the rear housing 120, the exhaust device's condensation effect on gas can be further improved.

[0050] Reference Figures 8 to 12In some embodiments, in the first channel 200, the thickness of the first channel 200 is a1, the length of the first spoiler column 240 provided on the front shell 110 is b1, and the length of the first spoiler column 240 provided on the rear shell 120 is c1, wherein a1<b1+c1, and the first spoiler column 240 provided on the front shell 110 and the first spoiler column 240 provided on the rear shell 120 are arranged alternately; in the second channel 300, the thickness of the second channel 300 is a2, the length of the second spoiler column 310 provided on the front shell 110 is b2, and the length of the second spoiler column 310 provided on the rear shell 120 is c2, wherein a2>b2+c2, and the first spoiler column 240 provided on the front shell 110 and the first spoiler column 240 provided on the rear shell 120 are arranged opposite to each other.

[0051] By adopting the above structure, the first spoiler posts 240 provided on the front housing 110 are arranged in an interlaced manner with the first spoiler posts 240 provided on the rear housing 120, thereby increasing the spoiler effect on the gas in the first channel 200, effectively reducing the gas temperature, and better condensing the gas. By arranging the first spoiler posts 240 provided on the front housing 110 and the first spoiler posts 240 provided on the rear housing 120 relative to each other, due to a2>b2+c2, a gap is formed between the two relatively arranged first spoiler posts 240, thereby facilitating the passage of gas, making it possible to cool and condense the gas while also facilitating the rapid discharge of the gas.

[0052] It is understandable that the first spoiler column 240 provided on the front housing 110 and the first spoiler column 240 provided on the rear housing 120 are arranged opposite to each other. Figures 8 to 12 As an exemplary illustration, in some embodiments, the first spoiler column 240 provided on the front housing 110 and the first spoiler column 240 provided on the rear housing 120 may be staggered, which is not specifically limited in the present invention.

[0053] Reference Figures 1 to 5 The outer side wall of the rear housing 120 is provided with three clamping portions 121 for fixing the wiring harness.

[0054] By adopting the above structure, when the exhaust device is installed on the outer wall of the inner tank of the dishwasher, the clamping portion 121 can assist in fixing the internal wiring harness of the dishwasher, avoiding the messy placement of the wiring harness inside the dishwasher, which is beneficial to improving the safety of the dishwasher.

[0055] It is understandable that the number of the clamping portions 121 can be one, two, four or more in addition to three. In addition, the clamping portions 121 can be arranged on the outer side wall of the rear shell 120 or on the outer side wall of the front shell 110, and this utility model does not make specific restrictions on this.

[0056] Reference Figures 1 to 10 In some embodiments, the exhaust channel further includes a third channel 400, which is located on the left side of the second channel 300 and extends downward. The left side wall of the second channel 300 is provided with a communication port 320 connected to the upper end of the third channel 400, and the exhaust port 102 is provided at the lower end of the third channel 400; the lower end of the second channel 300 has a water storage chamber 330, and the rear side wall of the water storage chamber 330 is provided with a water outlet 331, and the water outlet 331 has at least one water outlet hole connected to the water storage chamber 330. 332; The left side wall of the water storage chamber 330 is provided with a water hole 340 connected to the third channel 400, and the water hole 340 is located below the connecting port 320. The third channel 400 is provided with a water baffle 410, which is connected between the front side wall and the rear side wall of the exhaust channel, and the water baffle 410 extends downward from left to right to be connected with the bottom wall of the water hole 340. The left end of the water baffle 410 is provided with an upwardly extending blocking portion 411, and the blocking portion 411 is spaced apart from the left side wall of the third channel 400.

[0057] In the above structure, the second channel 300 is connected to the exhaust port 102 via the third channel 400. Specifically, the gas in the second channel 300 can flow leftward from the connecting port 320 into the third channel 400 and then flow downward along the third channel 400 to the exhaust port 102. As the gas flows downward along the second channel 300, condensed water formed by the condensation of the gas can accumulate in the water storage chamber 330 at the lower end of the second channel 300 and can be promptly discharged through the water outlet 332 of the water outlet portion 331. Furthermore, the condensed water formed in the third channel 400 can flow downward toward the water retaining plate 410. Because the water retaining plate 410 extends downward from left to right until it connects with the bottom wall of the water passage 340, it can guide the condensed water downward through the water passage 340, ultimately accumulating in the water storage chamber 330 and being promptly discharged through the water outlet 332 of the water outlet portion 331. In addition, since the left end of the water baffle 410 is provided with an upwardly extending blocking portion 411, the blocking portion 411 is spaced apart from the left side wall of the third channel 400. As a result, the gas can flow downward from the gap between the blocking portion 411 and the left side wall of the third channel 400 to the exhaust port 102, and the blocking portion 411 can prevent the condensed water from overflowing from the left end of the water baffle 410 and dripping downward to the exhaust port 102, thereby improving the dryness of the gas at the exhaust port 102.

[0058] It can be understood that by arranging the water outlet 331 on the rear side wall of the water storage chamber 330, that is, arranging the water outlet 331 on the rear shell 120, the rear shell 120 can be attached to the outer wall of the inner tank of the dishwasher during installation and the water inlet is connected to the inside of the inner tank. At the same time, a water inlet hole can also be opened on the inner tank, and the water outlet hole 332 of the water outlet 331 is connected to the water inlet hole, so that the condensed water accumulated in the water storage chamber 330 can be recovered into the inner tank of the dishwasher for cleaning the tableware.

[0059] Reference Figures 1 to 10 In some embodiments, the number of water outlet holes 332 is five, and the five water outlet holes 332 are arranged in a circular pattern. It is understood that the number of water outlet holes 332 may be one, two, three, four, six, or more, in addition to five, and this is not specifically limited in the present invention. When the number of water outlet holes 332 is at least three, all water outlet holes 332 may be arranged in a circular pattern, in a left-right direction, or in other arrangements, in addition to being arranged in a circular pattern, and this is not specifically limited in the present invention.

[0060] Reference Figures 1 to 7 In some embodiments, the left side wall of the second channel 300 is provided with an extension plate 321 extending downward to the connecting opening 320 of the shielding portion.

[0061] In the above structure, the setting of the extension plate 321 makes the opening area of ​​the connecting port 320 smaller than the opening area of ​​the end of the third channel 400 connected to the connecting port 320, thereby making the gas pressure of the second channel 300 near the connecting port 320 greater than the gas pressure of the third channel 400 near the connecting port 320, thereby conveniently guiding the gas in the second channel 300 to flow from the vent to the third channel 400.

[0062] Reference Figures 1 to 7 In some embodiments, the third channel 400 is provided with a first guide plate 420 located above the water baffle 410. The first guide plate 420 is connected to the left side wall of the third channel 400 and extends to the right to block the water baffle 410. The first guide plate 420 extends downward in the left and right directions and has a gap between it and the water baffle 410.

[0063] By adopting the above structure, the setting of the first guide plate 420 can guide the gas flow toward the water baffle 410. During this process, the gas can flow to the exhaust port 102 through the gap between the first guide plate 420 and the water baffle 410, and the condensed water formed by the condensation of the gas can flow along the water baffle 410 into the water storage chamber 330.

[0064] Reference Figures 1 to 7In some embodiments, the third channel 400 is further provided with two second guide plates 430 located below the water baffle 410. The two second guide plates 430 are correspondingly arranged on the left and right walls of the third channel 400 and are arranged in an inverted eight-shaped pattern. The lower ends of the two second guide plates 430 are spaced apart to form a guide channel 431. A fourth spoiler 440 is further provided in the third channel 400. The fourth spoiler 440 is located below the guide channel 431 and spaced apart from the two second guide plates 430. The fourth spoiler 440 has a spoiler groove 441 whose opening faces the guide channel 431. The width of the spoiler groove 441 in the left and right directions is greater than the width of the guide channel 431 in the left and right directions. The fourth spoiler 440 is spaced apart from the left wall of the third channel 400 and from the right wall of the third channel 400.

[0065] By adopting the above structure, the two second guide plates 430 are arranged in an inverted eight shape, which can guide the gas to flow downward to the guide channel 431 and flow toward the spoiler groove 441 of the fourth spoiler 440, and then flow downward along the gap between the fourth spoiler 440 and the second guide plate 430, and the gap between the fourth spoiler 440 and the left and right side walls of the third channel 400 to the exhaust port 102. This structure can disturb the gas again above the exhaust port 102, reduce the flow rate of the gas at the exhaust port 102, and avoid the gas from blowing directly from the exhaust port 102 quickly, thereby reducing the inconvenience or burns caused to the user when the gas is discharged from the exhaust port 102.

[0066] An embodiment of the present invention further provides a dishwasher, which is provided with the exhaust device of any of the above embodiments.

[0067] In the dishwasher of the present invention, by adopting the exhaust device of any of the above embodiments, when in use, the housing 100 of the exhaust device can be placed on the outer wall of the inner tank of the dishwasher and the air inlet 101 is connected to the interior of the inner tank. The hot and humid gas formed in the inner tank can flow into the exhaust channel of the housing 100 through the air inlet 101, and then flow through the first channel 200 and the second channel 300 in sequence, and finally be discharged from the exhaust port 102. Among them, the first guide portion 210 and the second guide portion 220 can both play a role in guiding the flow of gas, which is conducive to the rapid discharge of gas and can reduce the risk of gas backflow. In addition, the first spoiler structure and the second spoiler structure both adopt spoiler column structures, which not only can increase the contact area between the gas and the spoiler structure, but also can reduce the obstruction of the spoiler structure to the gas, so that the gas can pass smoothly through the gaps between the spoiler columns, thereby condensing the hot and humid air while facilitating the rapid discharge of the hot and humid air. Therefore, the arrangement of the exhaust device can facilitate the balance of air pressure between the inner tank of the dishwasher and the outside world, thereby facilitating the normal use of the dishwasher and improving the user experience.

[0068] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
