Description

Technical Field

[0001] The present application relates to the technical field of dishwashers, and in particular to a water storage tank and a dishwasher. Background Art

[0002] There are two types of dishwashers on the market: those without water tanks and those with water tanks. The first type is without water tanks, and the water intake and drainage of the dishwasher adopt the traditional method, and the structure is relatively simple. The second type is with water tanks, and the water intake or drainage of the dishwasher passes through the water tank structure, which can achieve energy or water saving effects. However, the dishwasher needs to be heated when working, and heating will cause the air pressure to expand, resulting in an imbalance of air pressure in the water tank, which will cause the water tank to fail to work properly, and in serious cases, it may also cause accidents such as the water tank rupture. Utility Model Content

[0003] Based on this, it is necessary to provide a water storage tank and a dishwasher to address the problem that the water tank is easily broken due to the heating during the operation of the dishwasher.

[0004] In a first aspect, a water storage tank of the present application comprises:

[0005] A water tank body, wherein a water storage cavity and a water inlet and a water outlet communicated with the water storage cavity are formed inside the water tank body, wherein the water inlet is used to be connected to an external water source, and the water outlet is used to be connected to a washing cavity of an inner tank of the dishwasher;

[0006] The water tank body is provided with a common channel, an overflow port, an air pressure balance channel and a condensation channel; the water storage chamber, the common channel and the overflow port are connected in sequence; one end of the air pressure balance channel is connected to the outside atmosphere; the other end of the air pressure balance channel is connected to the overflow port through the condensation channel; the overflow port is connected to the washing chamber; the common channel and the overflow port are distributed in sequence from top to bottom on the water tank body.

[0007] The water storage tank disclosed in the present application is connected in sequence with the washing chamber of the inner tank of the dishwasher through the air pressure balance channel, the common channel, the overflow port, and ensures the air pressure balance inside the water tank body during the use of the dishwasher, and avoids the air pressure expansion during the heating of the water tank body, which causes the air pressure imbalance in the water tank body, resulting in the water storage tank being unable to work normally, or even the water storage tank being broken; a large amount of steam is generated in the washing chamber due to the heating, and the steam enters the common channel and the air pressure balance channel through the overflow port. By also providing a condensation channel between the air pressure balance channel and the overflow port, the condensed water generated on the air pressure balance channel can be returned to the inner tank, reducing the steam discharged from the air pressure balance channel to the outside. The water storage tank based on the above structure can not only solve the problem that heating will cause the air pressure to expand, resulting in the air pressure imbalance in the water tank, resulting in the water tank being unable to work normally, but also complete the collection of condensed water, greatly improving the performance of the dishwasher.

[0008] In one embodiment, the condensation channel includes an upper condensation water channel, a condensation water storage chamber and a lower condensation water channel. The air pressure balance channel, the upper condensation water channel, the condensation water storage chamber, the lower condensation water channel and the overflow port are connected in sequence. The height of the upper condensation water channel on the water tank body is lower than the height of the air pressure balance channel on the water tank body. The height of at least part of the overflow port on the water tank body is lower than the height of the lower condensation water channel on the water tank body. The condensation water storage chamber is used to store condensation water of a certain height.

[0009] The water tank in the above embodiment further defines that the condensation channel is at least composed of an upper condensation water channel, a condensation water storage chamber and an underwater condensation water channel, wherein the upper condensation water channel is connected to the bottom of the air pressure balance channel, and steam can enter the common channel and the air pressure balance channel in sequence from the washing chamber, and steam can also enter the condensation channel directly from the washing chamber, and part of the steam condenses in the common channel and directly flows back to the overflow port, and the steam entering the air pressure balance channel condenses; the condensed water in the air pressure balance channel flows from the bottom of the air pressure balance channel through the upper condensation water channel and the condensation water storage chamber in sequence. When the condensed water exceeds a certain height, the condensed water exceeding the height flows into the overflow port through the underwater condensation water channel, and at this time, the upper condensation water channel, the condensation water storage chamber and the underwater condensation water channel form a blocked channel, which can hinder the steam from entering the air pressure balance channel from the condensation channel.

[0010] In one of the embodiments, the air pressure balance channel extends from top to bottom along the water tank body, the air pressure balance channel is U-shaped, an exhaust port is formed on the side of the air pressure balance channel away from the common channel, and the air pressure balance channel is connected to the outside atmosphere through the exhaust port.

[0011] The water storage tank in the above embodiment further limits the air pressure balance channel to be U-shaped, thereby increasing the air flow length of the steam in the air pressure balance channel, thereby increasing the amount of condensed water and reducing the amount of steam discharged to the outside from the exhaust port on the air pressure balance channel.

[0012] In one embodiment, the exhaust port is designed to be inclined, and the inclined direction of the exhaust port is toward the condensation channel.

[0013] The water tank in the above embodiment further defines that the exhaust port on the air pressure balance channel is inclined, and the inclined square of the exhaust port is facing the direction of the condensation channel. When steam enters the exhaust port in the air pressure balance channel, condensation is likely to occur. At this time, due to the inclined design of the exhaust port, condensed water formed at the exhaust port slides along the inclined surface of the exhaust port into the condensation channel, thereby preventing condensed water from dripping from the exhaust port onto other devices inside the dishwasher.

[0014] In one of the embodiments, a first notch is opened at the upper end of the common channel, and the common channel is connected with the air pressure balance channel through the first notch. The height of the common channel on the water tank body is higher than the height of the overflow port on the water tank body.

[0015] The water storage tank in the above embodiment further defines that the air pressure balance channel is connected to the common channel through a first opening at the upper end of the common channel, so that the steam in the washing chamber first passes through the entire common channel completely, part of the steam can condense in the common channel, and the remaining part enters the air pressure balance channel, thereby increasing the air flow path length of the steam, and then increasing the amount of condensed water, reducing the amount of steam discharged from the air pressure balance channel to the outside.

[0016] In one of the embodiments, a plurality of baffles are disposed in the common channel, and the plurality of baffles are staggeredly distributed on both sides of the common channel.

[0017] The water tank in the above embodiment is further limited to have multiple baffles alternately arranged on both sides of the common channel. After the steam enters the common channel from the overflow port, it is blocked by the multiple baffles, which can block the flow speed of the steam in the common channel. At the same time, the steam is easily condensed after contacting the baffles. Part of the steam has already condensed in the common channel to form condensed water that flows back into the washing chamber of the dishwasher inner tank.

[0018] In one of the embodiments, an overflow channel is further provided on the water tank body, the water storage chamber is connected with the common channel through the overflow channel, and the height of the overflow channel on the water tank body is higher than the height of the overflow port on the water tank body.

[0019] The water storage tank in the above embodiment further defines that the water storage chamber is connected to the public channel through an overflow channel, and the height of the overflow channel on the water tank body is higher than the height of the overflow port on the water tank body. When the clean water or waste water in the water storage chamber exceeds the warning line, that is, the liquid overflowing the overflow channel is transported to the washing chamber through the overflow channel and the overflow port in turn, thereby avoiding rupture of the water tank body due to excessive water pressure.

[0020] In one of the embodiments, a clean water channel is further provided on the water tank body, the water inlet is connected with the water storage chamber through the clean water channel, and the height of the clean water channel on the water tank body is higher than the height of the overflow channel on the water tank body.

[0021] The water tank in the above embodiment further defines that the water inlet is connected to the water storage chamber through the clean water channel, and the height of the clean water channel on the water tank body is higher than the height of the overflow channel on the tank body. Specifically, the drain port is selectively connected to the washing chamber through the control valve. When the control valve is in a closed state, the external water source passes through the water inlet, the clean water channel and the water storage chamber in sequence, and is finally stored in the water storage chamber. At this time, the water tank is used as a clean water storage tank; when the control valve is opened, the clean water in the water storage chamber enters the washing chamber through the water inlet as washing water; in addition, when the dishwasher completes washing, the waste water in the washing chamber can be transported to the water storage chamber through the drain port after the control valve is opened. At this time, the water tank is used as a waste water storage tank after the control valve is closed. Through the above structure, the water tank of the present application can have both clean water storage and waste water storage modes.

[0022] In one of the embodiments, the water tank body includes a front shell and a rear shell, the front shell and the rear shell enclose the water storage chamber, and the front shell and the rear shell are detachably connected.

[0023] In one embodiment, the water tank body is flat.

[0024] In a second aspect, the present application provides a dishwasher, comprising:

[0025] A water storage tank as any of the above;

[0026] The inner pot, the water storage tank is arranged on the side of the inner pot, the inner pot is connected to the water storage tank through a fixing nut, the fixing nut is provided with a plurality of through holes, and the overflow port is connected with the washing cavity formed by the inner pot through the plurality of through holes.

[0027] The present application provides a dishwasher, in which the water tank is fixed on the side of the inner tank by a fixing nut. Specifically, the inner tank is provided with a mounting port connected to the washing chamber, and the overflow port of the water storage bottle is formed with a thread matched with the fixing nut. The fixing nut partially passes through the mounting port and is threadedly connected with the overflow port. At the same time, since a plurality of through holes are provided on the fixing nut, the washing chamber can be connected with the overflow port through these through holes. By adopting the above-mentioned structure of the dishwasher, the dishwasher of the present application can not only solve the problem that heating will cause air pressure expansion, resulting in an imbalance of air pressure in the water tank, thereby causing the water tank to fail to work properly, but also complete the collection of condensed water, greatly improving the performance of the dishwasher.

[0042] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0044] like Figures 2 to 4 As shown, this embodiment provides a water storage tank, comprising:

[0045] The water tank body 10 has a water storage chamber 101 formed therein, and a water inlet 102 and a water outlet 103 communicated with the water storage chamber 101. The water inlet 102 is used to connect to an external water source, and the water outlet 103 is used to connect to the washing chamber 202 of the dishwasher inner tank 2;

[0046] A common channel 20, an overflow port 104, an air pressure balance channel 30 and a condensation channel 40 are provided on the water tank body 10. The water storage chamber 101, the common channel 20 and the overflow port 104 are connected in sequence. One end of the air pressure balance channel 30 is connected to the outside atmosphere, and the other end of the air pressure balance channel 30 is connected to the overflow port 104 through the condensation channel 40. The overflow port 104 is connected to the washing chamber 202. The common channel 20 and the overflow port 104 are distributed in sequence from top to bottom on the water tank body 10.

[0047] The water storage tank disclosed in the first aspect of the present application is connected in sequence with the washing chamber 202 of the inner tank 2 of the dishwasher through the air pressure balance channel 30, the common channel 20, the overflow port 104, to ensure the air pressure balance inside the water tank body 10 during the use of the dishwasher, to avoid the air pressure expansion during the operation and heating of the water tank body 10, which leads to the imbalance of air pressure inside the water tank body 10, so that the water storage tank 1 cannot work normally, or even the water storage tank 1 ruptures; a large amount of steam is generated in the washing chamber 202 due to the operation and heating, and the steam enters the common channel 20 and the air pressure balance channel 30 through the overflow port 104. By further providing a condensation channel 40 between the air pressure balance channel 30 and the overflow port 104, the condensed water generated on the air pressure balance channel 30 can be returned to the inner tank 2, reducing the steam discharged from the air pressure balance channel 30 to the outside. The water storage tank 1 based on the above structure can not only solve the problem that heating will cause the air pressure to expand, resulting in the imbalance of air pressure inside the water tank, so that the water tank cannot work normally, but also complete the collection of condensed water, greatly improving the performance of the dishwasher.

[0048] Specifically, the water inlet 102 and the water outlet 103 on the water tank body 10 are both located at the bottom of the water tank body 10 , and the heights of the water inlet 102 and the water outlet 103 on the water tank body 10 are lower than the height of the overflow port 104 on the water tank body 10 .

[0049] like Figures 3 to 7As shown, in addition to the features of the above-mentioned embodiments, the present embodiment further defines that: the condensation channel 40 includes an upper condensation water channel 41, a condensation water storage chamber 42 and a lower condensation water channel 43, the air pressure balance channel 30, the upper condensation water channel 41, the condensation water storage chamber 42, the lower condensation water channel 43 and the overflow port 104 are connected in sequence, the height of the upper condensation water channel 41 on the water tank body 10 is lower than the height of the air pressure balance channel 30 on the water tank body 10, the height of at least part of the overflow port 104 on the water tank body 10 is lower than the height of the lower condensation water channel 43 on the water tank body 10, and the condensation water storage chamber 42 is used to store condensation water of a certain height.

[0050] The above-mentioned water storage tank further defines that the condensation channel 40 is at least composed of an upper condensation water channel 41, a condensation water storage chamber 42 and a lower condensation water channel 43, wherein the upper condensation water channel 41 is connected to the bottom of the air pressure balance channel 30, and steam can enter the common channel 20 and the air pressure balance channel 30 in sequence from the washing chamber 202, and steam can also directly enter the condensation channel 40 from the washing chamber 202, and part of the steam condenses in the common channel 20 and then flows directly back to the overflow port 104, and the steam entering the air pressure balance channel 30 is condensed; the condensed water in the air pressure balance channel 30 flows from the bottom of the air pressure balance channel 30 through the upper condensation water channel 41 and the condensation water storage chamber 42 in sequence. When the condensed water exceeds a certain height, the condensed water exceeding the height flows into the overflow port 104 through the lower condensation water channel 43, and at this time, the upper condensation water channel 41, the condensation water storage chamber 42 and the lower condensation water channel 43 form a blocked channel, which can prevent steam from entering the air pressure balance channel 30 from the condensation channel 40.

[0051] like Figures 3 to 7 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the air pressure balance channel 30 extends from top to bottom along the water tank body 10, the air pressure balance channel 30 is U-shaped, and an exhaust port 301 is formed on the side of the air pressure balance channel 30 away from the common channel 20, and the air pressure balance channel 30 is connected to the outside atmosphere through the exhaust port 301.

[0052] The above-mentioned water storage tank further limits the air pressure balance channel 30 to be U-shaped, thereby increasing the air flow path length of the steam in the air pressure balance channel 30, thereby increasing the amount of condensed water and reducing the amount of steam discharged to the outside from the exhaust port 301 on the air pressure balance channel 30.

[0053] like Figures 4 to 6 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the exhaust port 301 is designed to be inclined, and the inclination direction of the exhaust port 301 is toward the condensation channel 40.

[0054] The above-mentioned water tank further defines that the exhaust port 301 on the air pressure balance channel 30 is inclined, and the inclined square of the exhaust port 301 is facing the direction of the condensation channel 40. When steam enters the exhaust port 301 in the air pressure balance channel 30, condensation is likely to occur. At this time, due to the inclined design of the exhaust port 301, the condensed water formed at the exhaust port 301 slides along the inclined surface of the exhaust port 301 into the condensation channel 40, thereby preventing the condensed water from dripping from the exhaust port 301 to other devices inside the dishwasher.

[0055] like Figure 4 and Figure 6 As shown, in addition to the features of the above-mentioned embodiments, this embodiment is further defined as follows: a first notch 201 is opened at the upper end of the common channel 20, the common channel 20 is connected to the air pressure balance channel 30 through the first notch 201, and the height of the common channel 20 on the water tank body 10 is higher than the height of the overflow port 104 on the water tank body 10.

[0056] The above-mentioned water storage tank further defines that the air pressure balance channel is connected to the common channel 20 through the first opening at the upper end of the common channel 20, so that the steam in the washing chamber 202 first passes through the entire common channel 20 completely, part of the steam can condense in the common channel 20, and the remaining part enters the air pressure balance channel 30, thereby increasing the air flow path length of the steam, and then increasing the amount of condensed water, and reducing the amount of steam discharged from the air pressure balance channel 30 to the outside.

[0057] like Figure 3 , Figure 4 , Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines that: a plurality of baffles 21 are disposed in the common channel 20 , and the plurality of baffles 21 are staggeredly distributed on both sides of the common channel 20 .

[0058] The above-mentioned water storage tank is further limited to have multiple baffles 21 staggeredly arranged on both sides of the common channel 20. After the steam enters the common channel 20 from the overflow port 104, it is blocked by the multiple baffles 21, which can block the flow speed of the steam in the common channel 20. At the same time, the steam is easily condensed after contacting the baffles 21. Part of the steam has already condensed in the common channel 20 to form condensed water that flows back into the washing chamber 202 of the dishwasher inner tank 2.

[0059] like Figure 3 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, the present embodiment further defines that: an overflow channel 60 is also provided on the water tank body 10, the water storage chamber 101 is connected with the common channel 20 through the overflow channel 60, and the height of the overflow channel 60 on the water tank body 10 is higher than the height of the overflow port 104 on the water tank body 10.

[0060] The above-mentioned water storage tank further defines that the water storage chamber 101 is connected to the public channel 20 through the overflow channel 60, and the height of the overflow channel 60 on the water tank body 10 is higher than the height of the overflow port 104 on the water tank body 10. When the clean water or waste water in the water storage chamber 101 exceeds the warning line, that is, the liquid overflowing the overflow channel 60 is transported to the washing chamber 202 through the overflow channel 60 and the overflow port 104 in turn, thereby avoiding rupture of the water tank body 10 due to excessive water pressure.

[0061] like Figure 3 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, the present embodiment is further defined as follows: a clean water channel 50 is also provided on the water tank body 10, the water inlet 102 is connected with the water storage chamber 101 through the clean water channel 50, and the height of the clean water channel 50 on the water tank body 10 is higher than the height of the overflow channel 60 on the water tank body 10.

Specifically, the drain port 103 is selectively connected to the washing chamber 202 through the control valve 70. When the control valve 70 is in a closed state, the external water source passes through the water inlet 102, the clean water channel 50 and the water storage chamber 101 in sequence, and is finally stored in the water storage chamber 101. At this time, the water storage tank 1 is used as a clean water channel. The water storage tank 1 is used; when the control valve 70 is opened, the clean water in the water storage chamber 101 enters the washing chamber 202 through the water inlet 102 as washing water; in addition, when the dishwasher completes washing, the waste water in the washing chamber 202 can be transported to the water storage chamber 101 through the drain port 103 after the control valve 70 is opened. At this time, the water storage tank 1 is used as a waste water storage tank 1 after the control valve 70 is closed; through the above structure, the water storage tank 1 of the present application can have both clean water storage and waste water storage modes.

[0063] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that the water tank body 10 includes a front shell 11 and a rear shell 12, the front shell 11 and the rear shell 12 enclose a water storage chamber 101, and the front shell 11 and the rear shell 12 are detachably connected.

[0064] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the water tank body 10 is flat.

[0065] In one embodiment, Figures 1 to 7 As shown, this embodiment provides a dishwasher, comprising:

Specifically, the inner tank 2 is provided with a mounting port 203 connected to the washing chamber 202, and the overflow port 104 of the water storage bottle is formed with a thread matched with the fixing nut 3. The fixing nut 3 partially passes through the mounting port 203 and is threadedly connected with the overflow port 104.

By adopting the dishwasher of the above structure, the dishwasher of the present application can not only solve the problem that heating will cause air pressure expansion, resulting in an imbalance of air pressure in the water tank, so that the water tank cannot work normally, but also complete the collection of condensed water, greatly improving the performance of the dishwasher.

[0069] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.
