Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a dishwasher. Background Technology

[0002] Traditional dishwasher drying methods generally fall into two categories: the first utilizes residual heat from inside the dishwasher for drying, and the second uses a heating module combined with a fan. The first method, using residual heat, doesn't require additional parts, but it necessitates heating the final wash to a very high temperature for effective drying, significantly impacting the overall energy consumption. In today's market demanding increasingly lower energy consumption, the second method, using a hot air device to deliver hot air into the inner drum, can greatly improve the drying effect of the dishes inside the dishwasher with only a slight increase in overall energy consumption. Furthermore, besides drying dishes after washing, hot air can also be circulated after long-term storage, reducing the risk of odors and bacterial growth. Therefore, more and more dishwashers on the market are adopting this drying method.

[0003] However, most dishwashers currently use a fixed drying mode for their hot air system, which cannot intelligently adjust the drying time or mode according to the condition of the dishes inside the dishwasher (such as when the dishes are freshly washed or when they have been stored for a long time), inevitably leading to some waste of resources. Utility Model Content

[0004] Therefore, it is necessary to address the issue that most dishwashers currently use fixed drying modes for their hot air devices, which cannot intelligently adjust the drying time or mode according to the condition of the dishes inside the dishwasher, inevitably leading to a certain waste of resources.

[0005] A dishwasher includes: an inner tub having a washing chamber; a hot air device disposed on an outer wall of the inner tub and communicating with the washing chamber, the hot air device generating hot air and blowing it into the washing chamber; a breather disposed on the outer wall of the inner tub and communicating with the washing chamber, the breather's air inlet being used to expel part of the gas in the washing chamber to balance the air pressure in the washing chamber; a sensor assembly disposed on the breather near the air inlet, the sensor assembly being used to detect the humidity and / or temperature of the vapor flow expelled from the breather; and a control device connected to both the hot air device and the sensor assembly, the control device being configured to control the hot air device based on detection signals fed back by the sensor assembly.

[0006] This application provides a dishwasher with a hot air device and a breather respectively connected to the washing chamber on the outer wall of its inner tub. When the dishwasher executes the drying program, the hot air device delivers hot air into the washing chamber to achieve drying, while some of the humid and hot air in the washing chamber can be discharged through the breather's vent, thereby balancing the air pressure in the washing chamber and ensuring smooth exhaust. Furthermore, by installing a sensor component on the breather, the sensor chip detects the humidity and / or temperature of the airflow discharged from the breather. The dishwasher's control device can then control the operation of the hot air device based on the humidity and / or temperature signals obtained from the sensor chip. For example, the control device can control the start and stop of the hot air device based on changes in the obtained humidity signal. The humidity value of the airflow gradually decreases as the hot air device operates, delivering hot air to dry the dishes in the washing chamber. When the humidity value drops to a preset value, the control device can stop the hot air device. Thus, the drying time of the dishes inside the dishwasher can be intelligently adjusted for different humidity levels, achieving better energy-saving effects. Furthermore, the control device can also adjust the hot air temperature based on the humidity signal value, thereby achieving a better balance between high efficiency and energy saving.

[0007] In one embodiment, a steam channel is formed within the respirator, with a first air inlet and a breathing port at each end of the steam channel. A first ventilation hole communicating with the washing chamber is provided on the side wall of the inner liner. The first air inlet communicates with the first ventilation hole, and the horizontal height of the breathing port is greater than that of the first air inlet. By employing this structure, when high-temperature water vapor in the washing chamber enters the steam channel through the first air inlet, it will spontaneously flow from the lower-positioned first air inlet to the higher-positioned breathing port and be discharged, thereby effectively improving the exhaust efficiency of the equipment.

[0008] In one embodiment, the respirator includes a housing and a baffle. A steam passage is formed within the housing. The baffle is disposed within the steam passage and located between the first air inlet and the breathing port. The baffle cooperates with the side wall of the steam passage to form an air passage opening. The first air inlet communicates with the steam passage through the air passage opening. The baffle creates a narrow air passage opening in the steam passage, thereby buffering the flow of water vapor, reducing its velocity, and ensuring that the water vapor flows more smoothly along the steam passage, thus better generating condensate.

[0009] In one embodiment, a drainage channel is formed within the respirator, with one end of the drainage channel connected to the steam channel. By providing the drainage channel, condensate in the steam channel can be promptly discharged to the outside or returned to the interior of the equipment, such as the washing chamber, effectively preventing condensate from accumulating and clogging the steam channel, and ensuring unobstructed steam discharge path.

[0010] In one embodiment, the respirator includes a housing and a first positioning part. The housing communicates with the washing chamber and has a breathing port. The first positioning part is disposed on the outer wall of the housing and located near the breathing port. The sensor assembly is positioned on the first positioning part. By adopting this structure, the sensor assembly is positioned and installed on the outside of the housing and close to the breathing port via the first positioning part, making the respirator easier to install, remove, and maintain. Furthermore, the sensor assembly can be placed in a relatively clean and dry environment, avoiding contact with detergent, food residue, and grease inside the washing chamber, effectively improving the accuracy of the detection results and preventing the sensor assembly from being contaminated or corroded. In addition, the sensor assembly directly detects the humidity / temperature of the vapor emitted from the breathing port. When the humidity is close to dry, it means that the moisture on the tableware has been largely evaporated and discharged, resulting in a more accurate drying effect.

[0011] In one embodiment, the first positioning part includes a buckle disposed on the outer wall of the housing. The buckle has a groove in which the sensor assembly is embedded. By embedding the sensor assembly through the groove on the buckle, rapid positioning and fastening of the sensor assembly are achieved, effectively preventing displacement or loosening of the sensor assembly during use or transportation, thereby improving the ease of assembly.

[0012] In one embodiment, the first positioning part further includes a positioning rib disposed on the side wall of the groove. The outer peripheral wall of the sensor assembly protrudes to form a boss, and the top or bottom wall of the boss abuts against the positioning rib. The mutual abutment between the positioning rib and the boss of the sensor assembly effectively prevents the sensor assembly from shifting or rotating within the groove, allowing for more precise positioning and a more secure installation of the sensor assembly.

[0013] In one embodiment, the sidewall of the groove opposite to the positioning rib is recessed outward to form a positioning groove, and the top and bottom walls of the boss abut against the sidewalls of the positioning rib and the positioning groove, respectively. By adopting the above structure, the positioning rib and the positioning groove cooperate to form a bidirectional constraint force on the boss, completely avoiding displacement gaps of the sensor assembly in all directions, and ensuring that the detection results of the sensor assembly can be stable and accurate.

[0014] In one embodiment, a first mounting groove is recessed on the top of the outer shell near the inner liner, and the vent is formed on the inner wall of the first mounting groove. At least a portion of the first positioning part and the sensor assembly are located within the first mounting groove. By forming a first mounting groove in the top of the outer shell for mounting the sensor assembly, the mounting structure becomes more compact, improving the utilization of internal space. Furthermore, the outer wall of the inner liner prevents the vapor from the vent from diffusing too quickly, thus ensuring that the sensor assembly can more fully contact the vapor to obtain more accurate humidity and / or temperature data.

[0015] In one embodiment, the respirator further includes a second positioning part, which is spaced apart from the first positioning part. The second positioning part has a locking hole, and the end of the sensor assembly away from the first positioning part is locked into the locking hole. By using the spaced-apart second positioning part and the first positioning part to fix both ends of the sensor assembly in the length direction, the structural volume of the positioning part can be effectively reduced, and it is convenient for the user to apply force to install and remove the sensor assembly.

[0016] In one embodiment, the sensor assembly includes a mounting body and a sensing chip. The mounting body is disposed on the respirator, and a second mounting groove with a downward-facing opening is provided on the side of the mounting body near the breathing port. The sensing chip is adapted to be installed in the second mounting groove. By adopting the above structure, the second mounting groove on the mounting body for mounting the sensing chip has a downward-facing opening, so that water droplets generated by condensation at the second mounting groove can quickly flow out and leave the sensing chip under the action of gravity, avoiding affecting the detection results of the rigid sensing chip due to condensation residue.

[0017] In one embodiment, the outer peripheral wall of the mounting body is provided with the boss.

[0018] In one embodiment, the hot air assembly includes a housing assembly, a heating element, and a fan. A hot air channel is formed inside the housing assembly, with a second air inlet and a second air outlet at each end. A second ventilation hole communicating with the washing chamber is provided on the side wall of the inner liner. The second air outlet communicates with the second ventilation hole. The heating element and the fan are installed within the hot air channel, and both are electrically connected to the control device. By adopting this structure, the control device can control the start and stop of the heating element and the fan according to changes in the obtained humidity signal. This allows for intelligent adjustment of the drying time of the dishes inside the dishwasher under different humidity conditions. Furthermore, the control device can also control the heating element to adjust the hot air temperature based on the humidity signal value, thereby achieving a better balance between high efficiency and energy saving.

[0019] In one embodiment, the second vent is located at the bottom of the inner liner.

[0020] In one embodiment, the hot air assembly is disposed on the same side as the respirator. Attached Figure Description

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0033] The dishwasher of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0034] like Figures 1 to 5 As shown, this embodiment discloses a dishwasher, including: an inner tub 1, the inner tub 1 having a washing chamber 101; a hot air device 2, the hot air device 2 being disposed on the outer side wall of the inner tub 1, the hot air device 2 being connected to the washing chamber 101, the hot air device 2 generating hot air and blowing it towards the washing chamber 101; a breather 3, the breather 3 being disposed on the outer side wall of the inner tub 1, the breather 3 being connected to the washing chamber 101, the breather 3 having a breather port 303 for discharging part of the gas in the washing chamber 101 to balance the air pressure in the washing chamber 101; a sensor assembly 4, the sensor assembly 4 being disposed on the breather 3 near the breather port 303, the sensor assembly 4 being used to detect the humidity and / or temperature of the steam flow discharged from the breather port 303; and a control device, the control device being connected to the hot air device 2 and the sensor assembly 4 respectively, the control device being configured to control the hot air device 2 based on the detection signal fed back by the sensor assembly 4.

[0035] This application provides a dishwasher, in which a hot air device 2 and a breather 3 are respectively connected to the washing chamber 101 of the inner tub 1 on the outer wall of the inner tub 1. When the dishwasher performs the drying program, the hot air device 2 delivers hot air into the washing chamber 101 to achieve drying. At the same time, some of the humid and hot air in the washing chamber 101 can be discharged through the breather 303, thereby balancing the air pressure in the washing chamber 101 and ensuring smooth exhaust. In addition, by setting a sensor assembly 4 on the breather 3, the sensing chip of the sensor assembly 4 will detect the humidity and / or temperature of the airflow discharged from the breather 303. Thus, the dishwasher control device can control the operation of the hot air device 2 according to the humidity and / or temperature signals obtained by the sensing chip. For example, the control device can control the start and stop of the hot air device 2 based on the obtained humidity signal changes. The humidity value of the airflow will gradually decrease as the hot air device 2 operates to dry the dishes in the washing chamber 101. When the humidity value drops to a preset value, the control device can control the hot air device 2 to stop working. Thus, the hot air device 2 can intelligently adjust the drying time of the dishes inside the dishwasher under different humidity conditions, achieving better energy-saving effects. Furthermore, the control device can also control the hot air device 2 to adjust the hot air temperature based on the humidity signal value, thereby better achieving a balance between high efficiency and energy saving.

[0036] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a steam channel 301 is formed inside the respirator 3, and a first air inlet 302 and a breathing port 303 are respectively provided at both ends of the steam channel 301. A first ventilation hole 102 communicating with the washing chamber 101 is provided on the side wall of the inner liner 1. The first air inlet 302 is connected to the first ventilation hole 102. The horizontal height of the breathing port 303 is greater than the horizontal height of the first air inlet 302. By adopting the above structure, when the high-temperature water vapor in the washing chamber 101 enters the steam channel 301 through the first air inlet 302, it can spontaneously flow from the lower first air inlet 302 to the higher breathing port 303 for discharge, thereby effectively improving the exhaust efficiency of the equipment.

[0037] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the respirator 3 includes a housing 31 and a baffle 32. A steam channel 301 is formed inside the housing 31. The baffle 32 is disposed in the steam channel 301 and located between the first air inlet 302 and the breathing port 303. The baffle 32 cooperates with the side wall of the steam channel 301 to form an air passage 304. The first air inlet 302 communicates with the steam channel 301 through the air passage 304. The baffle 32 forms a narrow air passage 304 in the steam channel 301, thereby playing a buffering role, reducing the flow rate of water vapor, and ensuring that water vapor can flow more smoothly along the steam channel 301 and generate condensate more effectively.

[0038] In addition to the features of the above embodiments, this embodiment further specifies that: a drainage channel is formed inside the breather 3, and one end of the drainage channel is connected to the steam channel 301. By setting the drainage channel, the condensate in the steam channel 301 can be discharged to the outside or flow back to the inside of the equipment, such as the washing chamber 101, in a timely manner, effectively preventing the accumulation of condensate and clogging of the steam channel 301, and ensuring the smooth flow of steam.

[0039] like Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the respirator 3 includes a housing 31 and a first positioning part 33. The housing 31 communicates with the washing chamber 101 and is provided with a breathing port 303. The first positioning part 33 is disposed on the outer wall of the housing 31 and located on the side close to the breathing port 303. The sensor assembly 4 is positioned on the first positioning part 33. By adopting the above structure, the sensor assembly 4 is positioned and installed on the outside of the housing 31 and close to the breathing port 303 through the first positioning part 33, making the respirator 3 easier to install, disassemble, and maintain. In addition, the sensor assembly 4 can be placed in a relatively clean and dry environment to avoid contact with detergent, food residue, and grease inside the washing chamber 101, which can effectively improve the accuracy of the detection results and prevent the sensor assembly 4 from being contaminated and corroded. Furthermore, the sensor assembly 4 directly detects the humidity / temperature of the steam flow discharged from the breathing port 303. When the humidity is close to dry, it means that the moisture on the tableware has basically evaporated and been discharged, and the drying effect is more accurate.

[0040] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first positioning part 33 includes a buckle 331, which is disposed on the outer wall of the housing 31. The buckle 331 has a groove 305, in which the sensor assembly 4 is embedded. By embedding the sensor assembly 4 through the groove 305 on the buckle 331, the sensor assembly 4 is quickly positioned and fastened, effectively preventing the sensor assembly 4 from shifting or loosening during use or transportation, thereby improving the ease of assembly.

[0041] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first positioning part 33 also includes a positioning rib 332, which is disposed on the side wall of the groove 305. The outer peripheral wall of the sensor assembly 4 protrudes to form a boss 42, and the top or bottom wall of the boss 42 abuts against the positioning rib 332. Through the mutual abutment between the positioning rib 332 and the boss 42 of the sensor assembly 4, the movement or rotation of the sensor assembly 4 within the groove 305 is effectively prevented, allowing the sensor assembly 4 to be positioned more accurately and installed more securely.

[0042] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the sidewall of the groove 305 opposite to the positioning rib 332 is recessed outward to form a positioning groove 306, and the top and bottom walls of the boss 42 abut against the sidewalls of the positioning rib 332 and the positioning groove 306, respectively. By adopting the above structure, the positioning rib 332 and the positioning groove 306 cooperate to form a bidirectional constraint force on the boss 42, completely avoiding displacement gaps of the sensor assembly 4 in all directions, and ensuring that the detection results of the sensor assembly 4 can be stable and accurate.

[0043] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first mounting groove 307 is recessed on the top of the outer shell 31 near the inner liner 1, and a vent 303 is provided on the inner wall of the first mounting groove 307. At least a portion of the first positioning part 33 and the sensor assembly 4 are located in the first mounting groove 307. By recessing the top of the outer shell 31 to form the first mounting groove 307 for mounting the sensor assembly 4, the mounting structure can be made more compact, which is beneficial to improving the utilization of internal space. Furthermore, under the shielding of the outer wall of the inner liner 1, the vapor flow discharged from the vent 303 can be prevented from diffusing too quickly, thereby ensuring that the sensor assembly 4 can make more sufficient contact with the vapor flow to obtain more accurate humidity and / or temperature data.

[0044] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the respirator 3 also includes a second positioning part 34, the first positioning part 33 and the second positioning part 34 are spaced apart, the second positioning part 34 is provided with a locking hole 308, and the end of the sensor assembly 4 away from the first positioning part 33 is locked into the locking hole 308. By using the spaced second positioning part 34 and the first positioning part 33 to fix the two ends of the sensor assembly 4 in the length direction, the structural volume of the positioning part can be effectively reduced, and it is convenient for the user to apply force to install and remove the sensor assembly 4.

[0045] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the sensor assembly 4 includes a mounting body 41 and a sensing chip. The mounting body 41 is disposed on the respirator 3. The mounting body 41 has a second mounting groove 401 with its opening facing downward on the side near the breathing port 303. The sensing chip is adapted to be installed in the second mounting groove 401. By adopting the above structure, the second mounting groove 401 on the mounting body 41 for mounting the sensing chip has its opening facing downward, so that water droplets generated by condensation at the second mounting groove 401 can quickly flow out and leave the sensing chip under the action of gravity, avoiding affecting the detection results of the rigid sensing chip due to the residue of condensate water.

[0046] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer peripheral wall of the mounting body 41 is provided with a boss 42.

[0047] like Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the hot air device 2 includes a housing assembly, a heating element, and a fan. A hot air channel 201 is formed inside the housing assembly. A second air inlet 202 and a second air outlet 203 are respectively provided at both ends of the hot air channel 201. A second ventilation hole 103 communicating with the washing chamber 101 is provided on the side wall of the inner liner 1. The second air outlet 203 communicates with the second ventilation hole 103. A heating element and a fan are installed inside the hot air channel 201, and the heating element and the fan are electrically connected to the control device. By adopting the above structure, the control device can control the start and stop of the heating element and the fan respectively according to the obtained humidity signal changes. Therefore, the hot air device 2 can intelligently adjust the drying time of the dishes inside the dishwasher under different humidity conditions. Furthermore, the control device can also control the heating element to adjust the hot air temperature according to the humidity signal value, thereby better achieving a balance between high efficiency and energy saving.

[0048] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the second ventilation hole 103 is located at the bottom of the inner liner 1.

[0049] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the hot air device 2 and the respirator 3 are arranged on the same side.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
