Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of kitchen equipment, in particular to a steam sterilization component and a dishwasher. Background Art
[0002] Dishwasher disinfection technologies include ozone, high-temperature, or steam. Ozone and high-temperature disinfection can damage dishwasher components, while steam disinfection offers excellent fluidity, improves temperature uniformity, and is less likely to damage dishwasher components. Current steam disinfection technologies for dishwashers typically use a steam generator, heating tubes, and other heating equipment to heat tap water to 100°C to generate steam, which is then passed into the dishwasher's inner tank to disinfect the dishes. However, this type of steam disinfection requires heating the cold tap water to 100°C, which increases the dishwasher's energy and water consumption. Summary of the Invention

[0043] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0044] like Figures 1 to 4 As shown, one embodiment discloses a steam sterilization component, including a box body 100, the box body 100 enclosing an inner cavity 101, a first heating element being provided in the inner cavity 101, a heating channel 120 being provided on the box body 100 and being separated from the inner cavity 101, a conveying element 110 being provided in the box body 100, the conveying element 110 being used to convey steam from the inner cavity 101 into the heating channel 120, the heating channel 120 being used to heat steam, a steam outlet 102 and a first air inlet 103 being provided on the inner wall of the inner cavity 101, and both ends of the heating channel 120 being connected to the steam outlet 102 and the first air inlet 103 respectively.
[0045] In the steam sterilization assembly, the first heating element can be used to heat water to form hot water for hot rinsing of articles. The evaporation of hot water will generate steam in the inner cavity 101. After the hot rinsing is completed, the hot water can be discharged, leaving the steam in the inner cavity 101. The conveying element 110 conveys the steam from the steam outlet 102 of the inner tank 150 into the heating channel 120. The heating channel 120 heats the steam to form high-temperature steam, which then re-enters the inner tank 150 through the first air inlet 103. The high-temperature steam can be used for sterilization. Since the steam sterilization assembly can utilize the steam generated in the hot rinsing stage and reheat it for subsequent sterilization, the waste heat is reused and the amount of water required to generate high-temperature steam is reduced. The steam entering the heating channel 120 still has a certain temperature, and the energy required for reheating is relatively small. Therefore, energy and water consumption can be effectively reduced, the cost of use is lower, and it is more energy-efficient. In addition, the additional delivery of steam to the inner cavity 101 can be reduced or eliminated, reducing the generation of condensed water, which is beneficial to the drying and sterilization of articles.
[0046] Optionally, the conveying member 110 may be a centrifugal fan installed at the steam outlet 102 to facilitate the suction of steam in the inner cavity 101 into the heating channel 120 .
[0047] In one embodiment, Figure 3 As shown, the housing 100 is provided with a drying and condensing channel 130 separated from the inner cavity 101, and a second air inlet 104 is provided on the inner wall of the inner cavity 101. The conveying member 110 is used to convey steam from the inner cavity 101 into the drying and condensing channel 130, where the steam is condensed to form dry air. The outlet of the drying and condensing channel 130 is connected to the second air inlet 104. Steam from the inner cavity 101 can also be conveyed into the drying and condensing channel 130 by the conveying member 110, where it is condensed to form dry air. The dry air is then discharged back into the inner cavity 101 through the second air inlet 104 to dry the items in the inner cavity 101. Since the condensed steam still has a certain temperature, the heat required for drying can be reduced, thereby achieving rapid drying.
[0048] Optionally, a cooling element is provided in the drying and condensing channel 130 to cool the steam by actively reducing the temperature.
[0049] In one embodiment, Figure 3As shown, the housing 100 is provided with a steam inlet channel 140, and a control member 141 is provided in the steam inlet channel 140. The steam inlet channel 140 is connected to the steam outlet 102. The heating channel 120 and the drying and condensing channel 130 are both connected to the steam outlet 102 through the steam inlet channel 140. The conveying member 110 is provided in the steam inlet channel 140, and the control member 141 is used to control the connection between the steam inlet channel 140 and the heating channel 120 or the drying and condensing channel 130. The control member 141 can be used to control the steam in the inner cavity 101 to enter the heating channel 120 or the drying and condensing channel 130, so that the steam can be reheated for steam sterilization or condensed and dried to form dry air for drying.
[0050] Specifically, since the cleaning and disinfection of articles, such as cleaning and disinfection of articles, will be performed in sequence, the steam entering the drying condensation channel 130 can be the steam generated after hot rinsing or the steam remaining after steam disinfection.
[0051] In other embodiments, two steam outlets 102 are provided on the inner cavity 101, and the two steam outlets 102 are respectively connected to the heating channel 120 and the drying and condensing channel 130. Two conveying members 110 are provided, and the two conveying members 110 are respectively provided in the heating channel 120 and the drying and condensing channel 130. The corresponding conveying member 110 can be activated as needed to achieve reheating or drying and condensing of the steam.
[0052] In one embodiment, Figure 3 As shown, the control member 141 includes a first baffle 141a, which is rotatably disposed within the steam inlet passage 140. The first baffle 141a has a first rotational position and a second rotational position. The first baffle 141a can reciprocate between the first and second rotational positions. When the first baffle 141a rotates to the first rotational position, the first baffle 141a is used to block the drying and condensing passage 130. When the first baffle 141a rotates to the second rotational position, the first baffle 141a is used to block the heating passage 120. By rotating the first baffle 141a, the entry of steam into the heating passage 120 or the drying and condensing passage 130 can be controlled, resulting in a simple and effective structure.
[0053] Optionally, the control member 141 further includes a motor connected to the first baffle 141 a , and the motor is used to control the rotation of the first baffle 141 a .
[0054] In other embodiments, the control component 141 may also be a three-way solenoid valve, the three ports of which are respectively connected to the steam inlet channel 140, the heating channel 120 and the drying and cooling channel, and the steam inlet channel 140 may also be connected to the heating channel 120 or the drying and cooling channel.
[0055] In one embodiment, Figure 3 As shown, the drying and condensing channel 130 is at least partially S-shaped. This allows the steam to travel a longer path through the drying and cooling channel, allowing the steam to cool and condense. This also reduces the space required for the drying and condensing channel 130, facilitating device miniaturization.
[0056] In other embodiments, the drying and condensing channel 130 is at least partially a spiral channel, which can also achieve the above effect.
[0057] In one embodiment, Figure 3 and 5 As shown, the drying and condensing channel 130 includes a first channel 131, an intermediate channel 132 and a second channel 133 which are connected in sequence. The inlet of the first channel 131 is connected to the steam outlet 102, and the outlet of the first channel 131 is arranged below the inlet of the first channel 131. The inlet of the second channel 133 is arranged above the outlet of the second channel 133. The outlet of the second channel 133 is connected to the second air inlet 104. The steam outlet 102 is located above the second air inlet 104. The bottom of the first channel 131 is a water accumulation part 134. The side wall of the water accumulation part 134 is provided with a drain outlet 135 which is connected to the bottom of the second channel 133. The curved arrangement of the first channel 131, the middle channel 132 and the second channel 133 increases the circulation distance of the steam. At the same time, the arrangement of the first channel 131 and the second channel 133 allows the condensed water generated after condensation to flow to the bottom under the action of gravity. The condensed water at the bottom of the first channel 131 can accumulate in the water accumulation part 134 and enter the bottom of the second channel 133 through the drain port 135 on the side wall of the water accumulation part 134 to discharge the condensed water and prevent the accumulation of condensed water.
[0058] Among them, since the outlet of the second channel 133 is connected to the second air inlet 104 and the outlet of the second channel 133 is located at the bottom of the second channel 133, the condensed water in the first channel 131 and the second channel 133 can be directly discharged into the inner cavity 101 through the second air inlet 104; or a water outlet is provided at the bottom of the second channel 133, and the water outlet is separated from the inner cavity 101. The condensed water can be drained through the water outlet and does not enter the inner cavity 101, so that the inner cavity 101 can be kept dry.
[0059] In one embodiment, Figure 6 and Figure 7As shown, a U-shaped channel 136 is provided within the drying and condensing channel 130. One end of the U-shaped channel 136 is connected to the drain outlet 135, and the other end of the U-shaped channel 136 is connected to the water accumulation portion 134. The lowest point of the U-shaped channel 136 is lower than the drain outlet 135. When condensed water is present in the water accumulation portion 134, the condensed water enters the U-shaped channel 136 and forms a water seal, preventing steam from directly entering the second channel 133 from the first channel 131 and being discharged into the inner cavity 101. When the water level of the condensed water is higher than the height of the drain outlet 135, the water pressure will transport the condensed water to the drain outlet 135 and into the second channel 133 for discharge.
[0060] Specifically, if Figure 5 and Figure 7 As shown, a first side baffle 137a and a second side baffle 137b are provided in the drying and condensing channel 130, and the first side baffle 137a and the second side baffle 137b form the intermediate channel 132. The drying and condensing channel 130 includes a top wall, a bottom wall 138, a left wall and a right wall. The first side baffle 137a and the left wall form the first channel 131, and the second side baffle 137b and the right wall form the second channel 133. The bottom wall 138 is spaced apart from the first side baffle 137a so that the first channel 131 is connected to the intermediate channel 132. The bottom wall 138 is connected to the second side baffle 137b. The drain port 135 is provided on the second side baffle 137b. On the baffle 137b, a structural member 139a is provided on the second side baffle, and the structural member 139a is spaced apart from the bottom wall 138. The second side baffle 137b, the structural member 139a and the bottom wall 138 are used to cooperate to form an "L"-shaped space. A blocking member 139b is provided on the bottom wall 138, and the blocking member 139b is provided on the side of the structural member 139a away from the drain outlet 135. The blocking member 139b is spaced apart from the structural member 139a. The blocking member 139b, the structural member 139a and the bottom wall 138 are used to cooperate to form an "I"-shaped space connected to the above-mentioned "L"-shaped space. The "L"-shaped space and the "I"-shaped space cooperate to form a U-shaped channel 136.
[0061] Specifically, the bottom end of the second side baffle 137b is an arc-shaped structure, which is used to match the shape of the second air inlet 104 to facilitate the discharge of gas.
[0062] In one embodiment, Figure 5As shown, the two opposing side walls within the first channel 131 are the first side wall and the second side wall, respectively. The first side wall is provided with a plurality of first ribs 131a spaced apart from the second side wall, and the second side wall is provided with a plurality of second ribs 131b spaced apart from the first side wall. The first ribs 131a and the second ribs 131b are spaced apart and arranged in a staggered manner, forming an S-shaped channel in the first channel 131. The first and second ribs 131a, 131b are arranged in a transverse direction. Steam passing through the first channel 131 has to travel a longer distance at one end, which lowers its temperature and causes condensation. The condensed water can flow down along the first and second ribs 131a, 131b, and gather at the bottom of the first channel 131 for easy collection and discharge.
[0063] In one embodiment, Figure 5 As shown, the two opposing side walls within the second channel 133 are the third side wall and the fourth side wall, respectively. The third side wall is provided with a plurality of third ribs 133a spaced apart from the fourth side wall, and the fourth side wall is provided with a plurality of fourth ribs 133b spaced apart from the third side wall. The third ribs 133a and the fourth ribs 133b are spaced apart and arranged in a staggered manner. The third ribs 133a and the fourth ribs 133b are both arranged to face downward in an inclined manner. The structure within the second channel 133 is similar to that within the first channel 131. Since the steam has a lower water content after passing through the first channel 131 and the intermediate channel 132, the condensed water generated on the third ribs 133a and the fourth ribs 133b is less and less likely to drip. To prevent the water droplets on the ribs from evaporating again, the third ribs 133a and the fourth ribs 133b are arranged to face downward in an inclined manner. This facilitates the dripping of the condensed water, thereby improving the dryness of the air when it is discharged from the second air inlet 104.
[0064] In one embodiment, Figure 3 and Figure 5 As shown, the inlet of the drying condensation channel 130 is arranged above the outlet of the drying condensation channel 130. This makes it easier for the condensed water produced after condensation to move under the action of gravity and be collected.
[0065] In one embodiment, Figure 6 As shown, the steam sterilization assembly further includes a first switch 200, which is disposed in the drying and condensing channel 130. The first switch 200 is used to control the connection or closure of the drying and condensing channel 130. The first switch 200 can prevent the steam in the inner cavity 101 from flowing back into the drying and condensing channel 130 through the second air inlet 104.
[0066] In one embodiment, Figure 6As shown, the first switch 200 includes a second baffle 210, a first limit member 220 and a first reset member 230. The first limit member 220 is provided on the side of the second baffle 210 away from the second air inlet 104. The second baffle 210 is hinged to the inner wall of the drying and condensing channel 130. The first reset member 230 is used to move the second baffle 210 in a direction close to the first limit member 220. When the second baffle 210 contacts the first limit member 220, the drying and condensing channel 130 is closed. When the conveying member 110 delivers steam into the drying condensation channel 130, wind can be generated in the drying condensation channel 130, and the wind can blow the second baffle 210 away from the first limiting member 220, so that the second baffle 210 and the first limiting member 220 no longer contact each other. At this time, the wind can continue to flow and enter the inner cavity 101 through the second air inlet 104, and no longer delivers steam into the drying condensation channel 130. The second baffle 210 is rotated back under the action of the first reset member 230 and contacts the first limiting member 220.
[0067] Specifically, the first reset member 230 is connected to the second baffle 210, and the part where the first reset member 230 is connected to the second baffle 210 is used to be hinged to the inner wall of the drying condensation channel 130. The weight of the first reset member 230 is used to move the second baffle 210 in a direction close to the first limit member 220, which is similar to the working principle of a seesaw.
[0068] In other embodiments, the second baffle 210 may be moved in a direction approaching the first limiting member 220 by utilizing only the weight of the second baffle 210 .
[0069] In other embodiments, the first restoring member 230 may also be a spring, a torsion spring, etc.
[0070] In other embodiments, the first switch 200 may also be a baffle controlled by a motor; or the first switch 200 may be a solenoid valve for controlling the connection or closing of the drying and condensing channel 130 .
[0071] In one embodiment, Figures 1 to 3 As shown, the box body 100 includes an inner liner 150 and a shell 160. The inner liner 150 encloses an inner cavity 101, and the shell 160 encloses a heating channel 120 and a drying and condensing channel 130. The shell 160 is detachably connected to the box body 100. This makes it easy to install and inspect and clean the interior of the shell 160.
[0072] Alternatively, as Figure 8 As shown, the box body 100 further includes a fixing clip 170, which is connected to the inner liner 150. The fixing clip 170 includes a first clamping portion 171 and a second clamping portion 172 that are spaced apart. The first clamping portion 171 and the second clamping portion 172 are used to engage with two opposite side surfaces of the shell 160, thereby achieving a detachable connection between the inner liner 150 and the shell 160.
[0073] Specifically, if Figure 8 As shown, both the first clamping portion 171 and the second clamping portion 172 are provided with a card slot, and the housing 160 is provided with a card column that engages with the card slot.
[0074] In one embodiment, Figure 1 and Figure 2 As shown, the inner liner 150 includes a first side 151 and a second side 152, and the shell 160 includes a main body 161 and an extension 162. The main body 161 is provided on the first side 151, and the extension 162 is connected to the main body 161. The extension 162 extends from the first side 151 to the second side 152. The steam inlet channel 140 and the drying and condensing channel 130 are both provided in the main body 161, and the heating channel 120 is provided in the extension 162. By arranging the main body 161 and the extension 162 on different sides, the heating channel 120 and the drying and condensing channel 130 can be prevented from interfering with each other. In addition, the spatial layout is reasonable, and the heating channel 120 can also transfer heat to the inner liner 150 during the steam heating process, which makes the heat transfer more uniform.
[0075] Optionally, the first side surface 151 and the second side surface 152 may be adjacent surfaces or non-adjacent surfaces.
[0076] Specifically, the clamping post is provided on the extension portion 162 .
[0077] In one embodiment, Figure 3 and Figure 4 As shown, a second heating element 121 is provided in the heating channel 120. The steam in the heating channel 120 can be heated again by the second heating element 121 so that the articles in the inner cavity 101 can be steam sterilized.
[0078] In one embodiment, the second heating element 121 is disposed along the length of the heating channel 120. In this case, the second heating element 121 can continuously heat the steam flowing therethrough, so that the steam is fully heated and the temperature rises faster.
[0079] In one embodiment, Figure 3 and Figure 4 As shown, the second heating element 121 is at least partially S-shaped, which can increase the contact area with the steam and allow the steam flowing therethrough to be fully heated.
[0080] In one embodiment, Figure 3 As shown, a plurality of temperature limiters 122 are provided in the heating channel 120, and the temperature limiters 122 are spaced apart along the length of the heating channel 120. The temperature limiters 122 can control the steam temperature, and the plurality of temperature limiters 122 can control the temperature of different areas in the heating channel 120 to ensure that the predetermined steam temperature is achieved.
[0081] In one embodiment, Figure 1 and Figure 4 As shown, the first air inlet 103 is located at the lower end of the inner cavity 101. At this time, the steam entering the inner cavity 101 through the first air inlet 103 has a higher temperature and can rise and sterilize the articles from bottom to top, which is more complete and has a better sterilization effect.
[0082] In one embodiment, Figure 9 As shown, the steam sterilization assembly further includes a second switch 300, which is disposed in the heating channel 120 and is used to control the connection or closure of the heating channel 120. The second switch 300 can prevent the steam in the inner cavity 101 from flowing back into the heating channel 120 through the first air inlet 103.
[0083] In one embodiment, Figure 9 As shown, the second switch 300 includes a third baffle 310, a second limit member 320 and a second reset member 330. The second limit member 320 is provided on the side of the third baffle 310 away from the first air inlet 103. The third baffle 310 is hinged to the inner wall of the heating channel 120. The second reset member 330 is used to move the third baffle 310 in a direction close to the second limit member 320. When the third baffle 310 contacts the second limit member 320, the heating channel 120 is closed. When the conveying member 110 delivers steam into the heating channel 120, wind can be formed in the heating channel 120, and the wind can blow the third baffle 310 away from the second limiting member 320, so that the third baffle 310 and the second limiting member 320 no longer contact each other. At this time, the wind can continue to flow and enter the inner cavity 101 through the first air inlet 103, and no longer delivers steam into the heating channel 120. The third baffle 310 is rotated back under the action of the second reset member 330 and contacts the second limiting member 320.
[0084] Specifically, if Figure 9 As shown, the second reset member 330 is connected to the third baffle 310, and the part where the second reset member 330 is connected to the third baffle 310 is used to hinge with the inner wall of the heating channel 120, and the weight of the second reset member 330 is used to move the third baffle 310 in a direction close to the second limit member 320.
[0085] In other embodiments, the third baffle 310 may be moved in a direction approaching the second limiting member 320 by utilizing only the weight of the third baffle 310 .
[0086] In other embodiments, the second restoring member 330 may also be a spring, a torsion spring, etc.
[0087] In other embodiments, the second switch 300 may also be a baffle controlled by a motor; or the second switch 300 may be a solenoid valve for controlling the connection or closing of the drying and condensing channel 130 .
[0088] One embodiment discloses a dishwasher comprising any of the above steam sterilization components.
[0089] In the above-mentioned dishwasher, the first heating element can be used to heat water to form hot water for hot rinsing of tableware. The evaporation of hot water will generate steam in the inner cavity 101. After the hot rinsing is completed, the hot water can be discharged to allow the steam to remain in the inner cavity 101. The conveying member 110 conveys the steam from the steam outlet 102 of the inner tank 150 into the heating channel 120. The heating channel 120 heats the steam to form high-temperature steam, which then re-enters the inner tank 150 through the first air inlet 103. The high-temperature steam can be used for disinfection. Since the above-mentioned dishwasher can utilize the steam generated in the hot rinsing stage and reheat it for subsequent disinfection, the waste heat is reused, and the amount of water required to generate high-temperature steam is reduced. The steam entering the heating channel 120 still has a certain temperature, and the energy required for reheating is relatively small. Therefore, it can effectively reduce energy consumption and water consumption, and has lower usage costs and is more energy-efficient.
[0090] In one embodiment, the first heating element is used to heat water during the rinsing stage. The hot rinsing stage generates steam, which can be transported to the heating channel 120 via the conveying element 110 and reused to reduce energy and water consumption.
