Abstract
Description
Technical Field
[0001] The present application relates to the technical field of condensing devices, and in particular to a condensing device for a dishwasher and a dishwasher. Background Art
[0002] At present, with the development of the dishwasher market, dishwashers are becoming more and more popular among users. At the same time, basic performance parameters such as washing, drying, energy consumption, and water consumption are also of concern to consumers.
[0003] The dishwasher heats the water at high temperature and then rinses and cleans the dishes by spraying. After the final rinsing stage, the following methods are commonly used for drying: 1. Residual temperature drying. If the temperature is low, the evaporation of residual water on the dishes is slow, and residual water still remains on the dishes at the end, resulting in a low drying rate and unsatisfactory drying effect; the higher the temperature, the better the drying effect, but it also brings the problem of increased energy consumption. 2. Automatic door drying. The dishwasher door is opened by the automatic ejection mechanism to dissipate the hot steam in the inner tank, but because the door is always open, it will cause secondary pollution. 3. Hot air drying. In the drying stage, at high temperature, internal ventilation is used to reduce the humidity in the inner cavity and maintain the continuous evaporation of water on the surface of the dishes. When the temperature of the inner cavity dishes is reduced, the temperature of the dishes is not enough to maintain the evaporation of water vapor, and the evaporation process is continued by increasing the air flow rate on the surface of the dishes. This method will generate a large amount of steam with a high temperature, which is directly discharged from the air outlet into the cabinet or kitchen. The cabinet may be deformed or moldy for a long time.
[0004] That is, after the dishwasher finishes washing, due to the high water temperature, a large amount of hot and humid steam will remain in the machine. During the drying stage, the hot and humid air in the inner cavity needs to be discharged as soon as possible to achieve rapid drying of the machine. At present, most dishwashers adopt direct exhaust, that is, the hot and humid air in the dishwasher is directly discharged to the outside of the machine. These high-temperature and high-humidity gases will condense when they encounter cold after passing to the outside. The exhaust ports of most dishwashers are under the doors, so that part of the steam exhausted by the wind condenses into water when it encounters the ground, which will mislead users into thinking that the machine is leaking; the other part of the steam that has not condensed in time will rise with the air and remain in the cupboard.
[0005] Therefore, the existing dishwasher has a problem that a large amount of hot and humid steam is produced after the cleaning operation, and the hot and humid steam has a high temperature and is easily condensed after being directly discharged, thereby reducing the drying effect of the dishwasher and the user experience.

[0040] Combined with reference Figure 1 , Figure 2 and Figure 3 In the first embodiment of the present application, a condensing device 5 for a dishwasher is provided, comprising: a condensing device body 51, on which a water inlet 521 and a water outlet 522 are provided; a condensing device bottom cover 52, which is correspondingly arranged at one side of the condensing device body 51, and the condensing device bottom cover 52 and the condensing device body 51 are enclosed to form a water channel cavity 54, and the water inlet 521, the water channel cavity 54 and the water outlet 522 are all connected; a condensing device top cover 53, which is correspondingly arranged at the other side of the condensing device body 51, and the condensing device top cover 53 and the condensing device body 51 are enclosed to form a water vapor cavity 55; a steam inlet 531 and a steam outlet 532 are provided on the condensing device top cover 53, and the steam inlet 531, the water vapor cavity 55 and the steam outlet 532 are all connected.
[0041] The condensing device bottom cover 52 and the condensing device top cover 53 are correspondingly arranged on both sides of the condensing device body 51, and the shapes and outer walls of the condensing device body 51, the condensing device bottom cover 52 and the condensing device top cover 53 correspond to each other; wherein, the condensing device body 51 and the condensing device bottom cover 52 enclose a water path cavity 54, and the condensing device bottom cover 52 and the condensing device top cover 53 enclose a water vapor cavity 55, and the steam introduced into the water vapor cavity 55 is cooled by passing cooling water into the water path cavity 54.
[0042] The water inlet 521, the water path cavity 54 and the water outlet 522 are all connected, and cooling water can be introduced from the water inlet 521, then flow into the water path cavity 54, and then flow out from the water outlet 522, so as to cool the condensing device bottom cover 52 and the condensing device body 51, forming a cooling water circuit; the steam inlet 531, the water vapor cavity 55 and the steam outlet 532 are all connected, and high-temperature steam can be introduced from the steam inlet 531, then pass into the water vapor cavity 55 for movement, and then pass out from the steam outlet 532. During the process, due to the cooling effect of the cooling water circuit on the condensing device body 51, heat will be absorbed when the steam contacts the condensing device body 51, thereby reducing the steam temperature or directly condensing the steam into cooling water.
[0043] The dishwasher condensing device 5 of this embodiment includes a condensing device body 51, a condensing device bottom cover 52 and a condensing device top cover 53. The condensing device body 51 and the condensing device bottom cover 52 enclose a water channel cavity 54, and the water inlet 521, the water channel cavity 54 and the water outlet 522 are all connected, which can be used as a cooling water circuit to cool the condensing device body 51 by using the flowing cooling water; the condensing device body 51 and the condensing device top cover 53 enclose a water vapor cavity 55, and the steam inlet 531, the water vapor cavity 55 and the steam outlet 532 are all connected, which is convenient for steam to enter, and then pass out after being cooled by the condensing device body 51; this dishwasher condensing device 5 can be used in a dishwasher, and before the steam is discharged, the cooling circuit is used to continuously absorb the heat in the steam, so as to achieve the effect of lowering the steam temperature and directly discharging it, or directly condensing the steam to reduce the amount of discharged steam, thereby improving the drying effect of the dishwasher and the user's experience.
[0044] In some embodiments, the condensing device body 51 includes an upper part 501, a middle part 502 and a lower part 503 arranged in sequence from top to bottom; a second extension piece 517 is arranged on the left side of the upper part 501 extending from top to bottom into the middle part 502, and there is a gap between the end of the second extension piece 517 facing away from the upper part 501 and the outer wall of the middle part 502; a first extension piece 513 is arranged on the right side of the middle part 502 extending from bottom to top into the upper part 501, and there is a gap between the end of the first extension piece 513 facing away from the middle part 502 and the outer wall of the upper part 501; a third extension piece 519 is arranged on the left side of the middle part 502 extending from bottom to top into the lower part 503, and there is a gap between the end of the third extension piece 519 facing away from the middle part 502 and the outer wall of the lower part 503. The flow path of the water vapor cavity 55 is lengthened by the first extension piece 513, the second extension piece 517 and the third extension piece 519, so that the steam can be fully retained in the water vapor cavity 55 and fully contact with the condensing device body 51, thereby reducing the temperature of the steam.
[0045] Further, the upper portion 501 includes a connecting member 511 and a plurality of guide members, the connecting member 511 being arranged corresponding to the steam inlet 531; the guide member being arranged on the side of the first extension member 513 away from the connecting member 511, and the guide member being located above the middle portion 502. The connecting member 511 is used to be arranged corresponding to the steam inlet 531 of the condensing device top cover 53, so as to stably enclose and connect the condensing device body 51 and the condensing device top cover 53, forming a water vapor cavity 55 that is sealed except for the steam inlet 531 and the steam outlet 532. Specifically, a clamping member is arranged on the inner side of the steam inlet 531 of the condensing device top cover 53, and the clamping member is clamped and fixed after abutting against the first connecting member 511.
[0046] The guide member is used to guide the flow of steam. The first extension member 513 separates the upper portion 501 into two regions, the left region and the right region. After the steam enters the steam inlet 531, it moves upward due to the obstruction of the first extension member 513 and then enters the left region. The plurality of guide members may include a second guide member 515 and a third guide member 516. The second guide member 515 and the third guide member 516 separate the left region into three paths, so that the steam entering the left region is dispersed and moves along three different paths, so that the steam can be evenly and fully contacted with the condensing device body 51, and the poor cooling effect caused by excessive concentration of steam can be prevented.
[0047] At the same time, the second guide member 515 is located above the third guide member 516, the maximum spacing distance between the second guide member 515 and the outer wall above is greater than the maximum spacing distance between the second guide member 515 and the third guide member 516, and the maximum spacing distance between the second guide member 515 and the third guide member 516 is greater than the maximum spacing distance between the third guide member 516 and the first extension member 513, which can better disperse the steam and prevent the steam from being too concentrated in a certain path.
[0048] Combined with reference Figure 5 The guide member may also include a first guide member 512 arranged above the connecting member 511, and the first guide member 512 is located between the connecting member 511 and the first extending member 513, and can block the upward movement of the introduced steam; at the same time, a first barrier member 514 extending from the top outer wall of the upper part 501 toward the direction close to the first extending member 513 is also provided inside the condensing device body 51, and the first barrier member 514 is arranged corresponding to the first extending member 513, and there is a gap between the first barrier member 514 and the first extending member 513 for the passage of steam; the first guide member 512, the first barrier member 514 and the first extending member 513 are all arranged to extend the movement path of the steam, thereby extending the time that the steam stays in the water vapor cavity 55 and improving the cooling effect.
[0049] Specifically, the gap between the first barrier member 514 and the first extension member 513 increases in the direction approaching the second guide member 515 and the third guide member 516 , that is, increases in the left direction, so that the steam entering along the first guide member 512 through the gap is diverted by the second guide member 515 and the third guide member 516 .
[0050] Furthermore, a plurality of first cooling plates 5171 are arranged at intervals on the second extension member 517, and a second cooling plate 5172 is arranged at a position corresponding to the first cooling plate 5171 in the middle part 502. The first cooling plate 5171 and the second cooling plate 5172 are in full contact with the steam, so that the temperature of the steam is reduced, or it is directly condensed into a liquid state. The first cooling plate 5171 and the second cooling plate 5172 are both located below the guide member, and the steam diverted by the guide member contacts the first cooling plate 5171 and / or the second cooling plate 5172 respectively, which can improve the cooling effect. Specifically, there is an angle between the second extension member 517 and the horizontal plane, and there is an angle between the corresponding position of the middle part 502 and the second extension member 517 and the horizontal plane, that is, the inclined arrangement can facilitate the steam to fully contact the first cooling plate 5171 and the second cooling plate 5172 during the movement from top to bottom.
[0051] The first cooling plate 5171 can be staggered with the second cooling plate 5172, and there are gaps between the first cooling plates 5171 and the second cooling plates 5172, which can ensure that the steam is in full contact with the first cooling plate 5171 and the second cooling plate 5172, further improving the cooling effect; the first cooling plate 5171 and the second cooling plate 5172 can be multiple, which can be set according to actual needs. Specifically, the first cooling plate 5171 and the second cooling plate 5172 can both be superimposed metal plates with corrugated shapes, and the metal plate has many flow channels that can be connected to the water channel cavity 54, and cooling medium can be added to the flow channels, thereby improving the cooling effect of the cooling plate.
[0052] The outer wall of the bottom end of the middle part 502 is arranged with the bottom end as the center and is arranged to meander upward in an arc along both sides, forming a water receiving cavity, which can receive liquid formed by cooling and condensing steam. In some embodiments, a condensation water outlet 533 is arranged on the top cover 53 of the condensing device, and the position of the condensation water outlet 533 corresponds to the bottom end of the middle part 502, which can be connected to the water receiving cavity to discharge the condensation water, thereby preventing the condensation water from evaporating again and releasing heat due to the inhalation of excessive steam.
[0053] Further, a second barrier 518 is provided at a position corresponding to the lower portion 503 and the third extension 519, and there is a gap between the second barrier 518 and the third extension 519. Specifically, the second barrier 518 is obtained by extending the top outer wall of the lower portion 503 in a direction close to the third extension 519, and the gap between the second barrier 518 and the third extension 519 is for steam to pass through, and the gap is the entrance of the lower portion 503, which can raise the height of the entrance, thereby increasing the difficulty of steam passing into the lower portion 503 and prolonging the retention time of steam in the water vapor cavity 55. Specifically, there is an angle between the second barrier 518 and the horizontal plane, and between the third extension 519 and the horizontal plane, which can further raise the height of the entrance and prolong the retention time of steam in the water vapor cavity 55.
[0054] The lower portion 503 is a vertically arranged strip structure, and preferably has a bending area on the lower portion 503 to extend the residence time of the steam in the water vapor cavity 55 and prevent the steam from falling rapidly due to gravity, resulting in poor cooling effect.
[0055] In some embodiments, the water inlet 521 and the water outlet 522 are both located at the bottom of the condensing device body 51 on the side away from the dishwasher condensing device 5, and the water inlet 521 is located below the water outlet 522; the steam inlet 531 is located at the top of the condensing device top cover 53, and the steam outlet 532 is located at the bottom of the condensing device top cover 53; the condensing device top cover 53 is also provided with a condensed water outlet 533, and the condensed water outlet 533 is located below the steam inlet 531. That is, steam expands upward due to high temperature, and the provision of the top steam inlet 531 and the bottom steam outlet 532 can extend the movement path of steam and improve the cooling effect; at the same time, the condensed water outlet 533 is provided below the steam inlet 531, which can conveniently receive steam condensed water and prevent the condensed water from absorbing too much heat and causing evaporation and heat dissipation.
[0056] Further, combined with reference Figure 3 and Figure 4 The bottom cover 52 of the condensing device is provided with a guide plate 523, one end of the guide plate 523 is located between the water outlet 522 and the water inlet 521, and the other end of the guide plate 523 is extended to the top of the bottom cover 52 of the condensing device; there is a gap between the other end of the guide plate 523 and the top of the bottom cover 52 of the condensing device; or, a through hole is provided on the other end of the guide plate 523. The gap at the top or the through hole on the guide plate 523 is the opening 5234 for cooling water to flow in.
[0057] The water inlet 521 is separated from the water outlet 522 by the guide plate 523, so that the cooling water flowing in from the water inlet 521 needs to be filled to the top, flows in from the gap or through hole at the top, and then is discharged from the water outlet 522, which prolongs the movement path of the cooling water and improves the cooling effect. Specifically, the water outlet 522 is preferably arranged at the bottom end of the bottom cover 52 of the condensing device.
[0058] Combined with reference Figure 2In some embodiments, the structure of the bottom cover 52 of the condensing device corresponds to the cooling system body, and both include an upper part 501, a middle part 502, and a lower part 503; wherein the surface of the upper part 501 is quasi-circular, circular, or elliptical, the surface of the middle part 502 is quasi-circular, circular, or elliptical, and the surface of the lower part 503 is a strip, and is a strip structure with a bending area. The connection between the middle part 502 and the upper part 501 is the first protrusion 5231, and the first protrusion 5231 corresponds to the steam inlet 531 of the top cover 53 of the condensing device. Specifically, the position of the condensing device body 51 corresponding to the first protrusion 5231 extends inward to obtain a first extension member 513, which is convenient for processing and manufacturing corresponding to the condensing device body 51 and the condensing device top cover 53. The connection between the middle part 502 and the lower part 503 is a second protrusion 5232. Specifically, the position of the condensing device body 51 corresponding to the second protrusion 5232 extends inward to obtain a third extension member 519. At the same time, the structure formed by the second protrusion 5232 and the outer wall of the middle part 502 is used to receive steam condensed water, and a condensed water outlet 533 is provided on the condensing device top cover 53 at a position corresponding to the bottom end of the middle part 502, which is convenient for processing and manufacturing corresponding to the condensing device body 51. At the same time, the arrangement of the first protrusion 5231 and the second protrusion 5232 makes the cooling water movement path from the water inlet 521 to the water outlet 522 more tortuous, extending the movement path of the cooling water and improving the cooling effect.
[0059] Combined with reference Figure 6 , Figure 7 and Figure 8 In the second embodiment of the present application, a dishwasher is provided, comprising the dishwasher condensing device 5 described in the first embodiment and its implementation mode. The dishwasher cools the steam generated during the dishwashing process through the dishwasher condensing device 5.
[0060] Combined with reference Fig. 9 In some embodiments, the dishwasher further comprises an inner tank 8, a breather 7 and a water tank 3, wherein the water tank 3 is disposed at the bottom of the inner tank 8, the dishwasher condensing device 5 and the breather 7 are both connected to the inner tank 8, and the breather 7 is connected to the water outlet 522; an inlet pipe 1 and a drain pipe 10 are disposed on the water tank 3, and the inlet pipe 1 is connected to the water inlet 521.
[0061] Among them, the inner tank 8 serves as the main body of the dishwasher, which is a hollow cavity structure, including a top surface, a bottom surface, a left side surface, a right side surface, a front surface and a back surface, a total of six surfaces forming a closed cleaning space, wherein the connection between the front surface and the other side surfaces is a snap connection, a magnetic connection or a detachable connection. When it is necessary to put in the items to be cleaned, the front surface is opened, and before putting in the items to be cleaned for cleaning, the front surface needs to be tightly fitted with the other side surfaces to make the inner tank 8 airtight to prevent water and oil stains from splashing during the cleaning process.
[0062] The water tank 3 is arranged at the bottom of the inner tank 8, that is, located on the bottom surface of the inner tank 8. Warm water or hot water is introduced into the water tank 3 through the water inlet pipe 1. The water tank 3 is provided with a sprayer, or a sprayer is provided on the side of the inner tank 8. The sprayer is connected to the water tank 3, so that water is introduced into the sprayer to spray the items to be cleaned at multiple angles, thereby washing away the stains, oil stains, dust, etc. on the items to be cleaned, and then the sprayed water flows back into the water tank 3 at the bottom and is discharged from the drain pipe 10. In addition, the water inlet pipe 1 is also connected to the water inlet 521, and the water is supplied to the condensing device 5 for the dishwasher through the water inlet pipe 1.
[0063] The respirator 7 and the dishwasher condensing device 5 are both located on the side wall of the inner tank 8. The respirator 7 is connected to the inner cavity of the inner tank 8, and air holes are provided on the respirator 7; during the drying process after cleaning, the respirator 7 can promote the exchange and circulation of air and moisture inside and outside the inner tank 8 through the air holes, thereby improving the drying efficiency and effect.
[0064] The dishwasher condensing device 5 is connected to the inner cavity of the inner tank 8. Specifically, the steam inlet 531 is connected to the exhaust port of the inner tank 8, so that the gas discharged from the inner tank 8 can be passed into the dishwasher condensing device 5 through the steam inlet 531, and discharged from the steam outlet 532 through the water vapor cavity 55. During the process, the gas is fully in contact with the condensing device body 51, thereby reducing the steam temperature, or the steam is condensed and discharged from the condensed water outlet 533, thereby reducing the temperature of the discharged high-temperature steam or reducing the amount of discharged high-temperature steam.
[0065] Among them, the water outlet 522 of the dishwasher condensing device 5 is connected to the breather 7, and the condensed water outlet 533 of the dishwasher condensing device 5 is also connected to the breather 7. Cooling water and condensed water can be passed into the breather 7 to help balance the internal pressure, and can further ensure the exchange and circulation of air and moisture inside and outside the inner tank 8, thereby realizing the secondary utilization of cooling water and condensed water.
[0066] The water outlet 522 of the dishwasher condensing device 5 can be connected to the respirator 7 through the water outlet pipe 2; the water inlet pipe 1 introduces cooling water into the water inlet 521, and then passes through the water channel cavity 54 of the dishwasher condensing device 5, and flows into the respirator 7 through the water outlet 522 and the water outlet pipe 2 for secondary utilization; the condensed water obtained by condensing the steam introduced into the dishwasher condensing device 5 in the condensation cavity can also be introduced into the respirator 7 through the condensed water outlet 533 for secondary utilization.
[0067] In some embodiments, the dishwasher further includes a water softener, which is connected to the water tank 3 and is provided with a dry air outlet 9. The water softener is connected to the water tank 3 and is used to filter and soften the water passed into the water tank 3, thereby reducing the calcium, magnesium ions and other components in the water that easily lead to increased water hardness, and can effectively reduce the generation of scale, prevent scale from clogging the water tank 3, and extend the service life of the dishwasher. Specifically, the water tank 3 is connected to the water softening pipe 4 through the water inlet pipe 31, so that water is passed into the water softening pipe 4 for softening treatment; the water softening pipe 4 is connected to the sprayer, and the softened water can be sprayed through the sprayer.
[0068] The water softening pipe 4 is also provided with an air outlet 9 for discharging waste water and gas generated during the softening process to ensure the cleanliness and drying of the inside of the dishwasher. At the same time, the water softening pipe 4 is also connected to the inner cavity of the inner tank 8, which can help to remove the hot and humid air in the inner tank 8 during the drying process after cleaning, thereby improving the drying efficiency and effect. The water softening pipe 4 is connected to the respirator 7, and the water in the respirator 7 can be processed by the water softening pipe 4 and then flow into the water tank 3.
[0069] Furthermore, the water inlet pipe 1 is provided with a water inlet pump 11, which can pressurize water into the water inlet pipe 1 through the water inlet pump 11, adjust the water inlet flow rate, and improve the water inlet efficiency; at the same time, the water inlet pipe 1 is also provided with a water inlet valve 12, which can control the opening and closing of the water inlet pipe 1, and can stop the water inlet when the dishwasher is abnormally started to prevent water waste. The drain pipe 10 is also provided with a drain pump 21, which can pump out the water in the drain pipe 10 by the drain pump 21, adjust the drainage flow rate, improve the drainage efficiency, and prevent excessive water from accumulating in the dishwasher. A base 6 can be provided below the inner tank 8 to fix the position of the inner tank 8.
[0070] Specifically, after the washing operation of the dishwasher and before the drying stage begins, the water inlet valve 12 is used to control the water inlet pipe 1 to fill the water path cavity 54 of the dishwasher condensing device 5 with cold water as cooling water, and the water inlet is stopped. At this time, the hot and humid air or steam in the inner tank 8 is passed into the water vapor cavity 55 through the steam inlet 531. Due to the presence of the water path cavity 54 and the cooling plate, a large amount of hot and humid air or steam will be converted into condensed water, and then flow into the respirator 7 through the condensed water outlet 533, and finally flow into the water tank 3 from the respirator 7 and be pumped out of the dishwasher through the drain pipe 10 by the drain pump 21. In this stage, a small amount of water vapor will be discharged to the outside of the dishwasher through the drying air outlet 9, but because most of the water vapor has been converted into condensed water and there is a dishwasher condensing device 5, the amount of water vapor discharged is small and the temperature is low, which will not cause damage to the user. When the cooling water in the water channel cavity 54 rises to a certain temperature due to heat absorption, the water inlet valve 12 can be started to let in water, and the heated cooling water in the water channel cavity 54 is squeezed into the respirator 7 through the water outlet 522, and finally enters the water channel trough 3 through the groove into the water pipe 31, and is discharged by the drainage pump 21.
[0071] Specifically, the dishwasher may further include a controller, and the inner tank 8, the respirator 7, the water tank 3, the water softening pipe 4 and the dishwasher condensing device 5 may be provided with temperature sensors, liquid flow sensors and gas flow sensors, so that the water inlet valve 12, the drain pump 21, the water inlet pipe 1, the water outlet pipe 2, the drain pipe 10, etc. can be adjusted according to the temperature and amount of the liquid (including the water passed into the water tank 3, the water passed into the dishwasher condensing device 5, etc.) and the gas (the hot and humid air in the inner tank 8, steam, etc.), thereby improving the cleaning effect, cleaning efficiency and drying effect and drying efficiency of the dishwasher.
[0072] In summary, the present application provides a condensing device for a dishwasher and a dishwasher, wherein the condensing device for the dishwasher comprises a condensing device body, a condensing device bottom cover and a condensing device top cover, the condensing device body and the condensing device bottom cover are enclosed to form a water channel cavity, the water inlet, the water channel cavity and the water outlet are all connected, and can be used as a cooling water circuit, and the flowing cooling water is used to cool the condensing device body; the condensing device body and the condensing device top cover are enclosed to form a water vapor cavity, the steam inlet, the water vapor cavity and the steam outlet are all connected, so as to facilitate the entry of steam, and then pass it out after being cooled by the condensing device body; this condensing device for a dishwasher can be used in a dishwasher, and before the steam is discharged, the cooling circuit is used to continuously absorb the heat in the steam, so as to achieve the effect of lowering the steam temperature and directly discharging it, or directly condensing the steam to reduce the amount of discharged steam, thereby improving the drying effect of the dishwasher and the user's experience.
