Description

Technical Field

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

[0002] With the quickening pace of life, dishwashers are being accepted and used by more and more families because they can quickly clean tableware, liberating both users and sterilizing tableware. They can cope with the tableware used in daily life, especially the numerous tableware after family gatherings, saving users a lot of post-meal time.

[0003] When cleaning in a dishwasher, water is sprayed out through a rotating arm to clean the dishes. Hot water is generally used for cleaning. In order to achieve the effect of high-temperature disinfection, high-temperature steam is also usually used for cleaning. However, in the process of continuously spraying water vapor for cleaning, the pressure in the dishwashing chamber of the dishwasher will continue to increase. In order to prevent excessive pressure, an exhaust structure will be installed in the dishwasher to discharge steam. After cleaning, the cleaning chamber is still in a high-temperature state. If the door is opened directly, the user may be scalded. At the same time, after high-temperature cleaning is completed, the dishes need to be dried, but most existing dishwashers do not have a special steam discharge structure, or the steam discharge structure is not designed reasonably, resulting in low drying effect and efficiency. Utility Model Content

[0004] Based on this, it is necessary to provide a dishwasher to solve the above problems of the existing dishwashers.

[0005] The dishwasher provided in the present application comprises a steam exhaust device, wherein the steam exhaust device is arranged on an inner tank of the dishwasher;

[0006] The steam discharge device comprises a discharge channel and a suction assembly, wherein the suction assembly is installed in the discharge channel, and the discharge channel is provided with an air inlet and an air outlet, wherein the air inlet is distributed at the top of the inner tank, and the air inlet is communicated with the washing chamber formed by the inner tank;

[0007] The suction assembly is used to guide the steam in the washing chamber into the exhaust channel and exhaust it through the exhaust port.

[0008] The dishwasher disclosed in the present application is connected to the washing chamber through a discharge channel. When the suction component is working, the steam in the washing chamber is sucked into the discharge channel through the air inlet and then discharged through the exhaust port, so as to reduce the steam content in the washing chamber and achieve drying of the washing chamber. Based on the design that the air inlet of the discharge channel is distributed at the top of the inner tank, the steam in the washing chamber can be sucked into the washing chamber as much as possible and then discharged, thereby avoiding the problem of low drying efficiency of the dishwasher due to the steam that has risen to the top of the washing chamber not being able to be sucked into the discharge channel and discharged in time.

[0009] In one of the embodiments, the number of the air inlet is not less than one, and at least one of the air inlet is spaced apart and distributed on the top of the inner container.

[0010] The dishwasher in the above embodiment further defines that the exhaust channel has at least one air inlet. By having at least one air inlet spaced apart on the top of the inner pot, the risk of one of the air inlets being clogged by residual food, resulting in the inability to discharge steam in a timely manner, can be avoided.

[0011] In one embodiment, the exhaust channel is formed with a plurality of channel branches at the air inlet end, the number of the channel branches is consistent with the number of the air inlets, and the air inlet is formed on each of the channel branches.

[0012] The dishwasher in the above embodiment further defines that the discharge channel is provided with a plurality of channel branches at the air inlet end, each channel branch corresponds to an air inlet, and the steam in the washing chamber can enter the corresponding channel branches through the plurality of air inlets, and finally converge together and be discharged. By setting a plurality of channel branches, the efficiency of steam discharge is accelerated and the drying time of the dishwasher is shortened.

[0013] In one embodiment, the steam discharge device also includes a valve assembly, which is installed in the discharge channel. The valve assembly is linked to the suction assembly. When the suction assembly is turned on, the valve assembly opens the discharge channel; when the suction assembly is closed, the valve assembly cuts off the discharge channel.

[0014] The dishwasher in the above embodiment further defines a valve assembly in the discharge channel for controlling the conduction or cutoff of the discharge channel. The valve assembly can be linked with the suction assembly. When the suction assembly is turned on, the valve assembly is in an open state, and steam can be discharged from the discharge channel; when the suction assembly is turned on, the valve assembly is in a closed state, thereby preventing the dishwasher from discharging steam from the discharge channel to the outside during high-temperature cleaning, resulting in too low a temperature in the washing chamber and poor high-temperature cleaning effect.

[0015] In one of the embodiments, the air inlet, the valve assembly, the suction assembly and the air outlet are sequentially distributed on the discharge channel.

[0016] The dishwasher in the above embodiment further defines that the air inlet, valve assembly, suction assembly and exhaust port are distributed in sequence on the discharge channel. When the suction assembly is closed, the valve assembly can block the high-temperature steam from flowing into the suction assembly, thereby reducing damage to the suction assembly caused by the high-temperature steam.

[0017] In one embodiment, the valve assembly includes a baffle, which is rotatably disposed in the discharge channel to form at least a first position and a second position; when the suction assembly is closed, the baffle is in the first position; when the suction assembly is opened, the baffle rotates from the first position to the second position.

[0018] The dishwasher in the above embodiment further defines that a rotatable baffle is provided in the discharge channel, and when the suction assembly is in a closed state, the baffle is located at a first position, and the baffle can block the high-temperature steam from being discharged from the discharge channel. When the suction assembly is in an open state, under the action of the suction force generated by the suction assembly, the baffle rotates from the first position to the second position, and at this time, the steam can be discharged from the discharge channel to the outside along the suction direction.

[0019] In one of the embodiments, a blocking block is formed in the exhaust channel, and the blocking block is located between the air inlet and the baffle. When the baffle is in the first position, the projection of the blocking block on the baffle is located at the bottom of the baffle and lower than the rotation point of the baffle.

[0020] The dishwasher in the above embodiment further defines that a blocking block is provided between the air inlet and the baffle in the exhaust channel, and the blocking block is located below the baffle and below the rotation point. Since the density of steam is smaller than that of air, the steam enters the exhaust channel and gathers above the channel. If the lower part of the baffle is not blocked by the blocking block, the steam continuously impacts the upper part of the baffle, which can easily cause the baffle to rotate, resulting in leakage in the exhaust channel when the suction assembly is closed.

[0021] In one embodiment, the exhaust ports are distributed on the side walls of the inner container.

[0022] The dishwasher in the above embodiment further defines that the exhaust port of the discharge channel is distributed on the side wall of the inner tank to prevent the steam discharged from the exhaust port from blowing directly toward the user when the user operates in front of the dishwasher, thereby preventing burns.

[0023] In one embodiment, the discharge channel can be divided into a first channel and a second channel, the first channel is respectively at the top of the inner tank, and the second channel is distributed on the side wall of the inner tank, the connection between the first channel and the second channel is an arc-shaped design, the suction assembly is installed in the first channel, and the air outlet of the suction channel is close to the connection between the first channel and the second channel.

[0024] The dishwasher in the above embodiment further defines that the second channel in the discharge channel is distributed on the side wall of the inner tank, the connection between the first channel and the second channel is an arc-shaped design, and the suction assembly is installed in the first channel and close to the connection, so that liquid water condensed at the air outlet of the suction assembly can slide along the arc-shaped channel under the action of its own gravity, thereby avoiding long-term water accumulation in the suction assembly, causing bacterial growth or affecting the normal operation of electronic components in the suction assembly.

[0025] In one of the embodiments, the steam exhaust device further includes a filter assembly, wherein the filter assembly is disposed on the inner tank and located at the air inlet, and the washing chamber, the filter assembly and the air inlet are connected in sequence.

[0026] The dishwasher in the above embodiment further defines a filter assembly disposed at the air inlet of the inner tank in the washing chamber, so as to prevent residual food from entering the discharge channel during the steam discharge process of the washing chamber, which is not only troublesome to clean, but also easy to clog the discharge channel and damage the suction assembly.

[0036] 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.

[0037] 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.

[0038] like Figures 1 to 5 As shown, this embodiment provides a dishwasher, comprising:

[0039] A steam exhaust device, which is arranged on the inner tank 2 of the dishwasher;

[0040] The steam discharge device includes a discharge channel 10 and a suction assembly 20, the suction assembly 20 is installed in the discharge channel 10, the discharge channel 10 is provided with an air inlet 101 and an air outlet 102, the air inlet 101 is distributed on the top of the inner tank 2, and the air inlet 101 is communicated with a washing chamber 201 formed by the inner tank 2;

[0041] The suction assembly 20 is used to guide the steam in the washing chamber 201 into the exhaust channel 10 and exhaust it through the exhaust port 102 .

[0042] The suction component 20 can guide the steam in the washing chamber 201 into the exhaust channel 10 through the air inlet 101 and then exhaust it. The suction component 20 can be a blower and an air pump. Exemplarily, the suction component 20 is a blower, and the blower works in the exhaust channel 10 to form suction, and the steam in the washing chamber 201 is sucked into the exhaust channel 10 through the air inlet 101, and then exhausted through the exhaust port 102, so as to reduce the steam content in the washing chamber 201 and achieve drying of the washing chamber 201.

[0043] The two ends of the discharge channel 10 are respectively an air inlet 101 and an air outlet 102. The air inlet 101 is distributed at the top of the inner tank 2 and communicates with the washing chamber 201 of the inner tank 2. The air outlet 102 can be distributed at the top or side wall of the inner tank 2. Since the air inlet 101 is distributed at the top of the inner tank 2, compared with setting the air inlet 101 on the side wall of the inner tank 2, it can be avoided that the steam that has risen to the top of the washing chamber 201 cannot be sucked into the discharge channel 10 and discharged in time, causing this part of the steam to stay at the top of the washing chamber 201 or liquefy, and the moisture in the washing chamber 201 cannot be discharged as low as possible, thereby resulting in low drying efficiency of the dishwasher.

[0044] The discharge channel 10 may have a shell structure with openings at both ends. For example, the shell structure includes an upper shell and a lower shell, the upper shell and the lower shell enclose an interior to form the discharge channel 10, and the lower shell is formed with an air inlet 101 connected to the washing chamber 201. In some embodiments, the lower shell and the inner tank 2 are an integrally formed structure, and the upper shell and the lower shell are detachably connected. It should be noted that in other embodiments, the lower shell and the inner tank 2 are detachably connected.

[0045] The dishwasher disclosed in the present application is connected to the washing chamber 201 through the discharge channel 10. When the suction component 20 is working, the steam in the washing chamber 201 is sucked into the discharge channel 10 through the air inlet 101, and then discharged through the exhaust port 102, so as to reduce the steam content in the washing chamber 201 and achieve drying of the washing chamber 201. Based on the design that the air inlet 101 of the discharge channel 10 is distributed at the top of the inner tank 2, the steam sucked into the washing chamber 201 can be discharged after being discharged from the washing chamber 201 as much as possible, thereby avoiding the problem of low drying efficiency of the dishwasher due to the steam that has risen to the top of the washing chamber 201 not being able to be sucked into the discharge channel 10 and discharged in time.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the number of the air inlet 101 is not less than one, and the air inlet 101 is not less than one and is distributed at intervals on the top of the inner liner 2 .

[0047] There is at least one air inlet 101 of the exhaust passage, and at least one air inlet 101 is distributed at intervals on the top of the inner pot 2, which can avoid the risk of one of the air inlets 101 being blocked by residual food, resulting in the inability to discharge steam in time. Exemplarily, there are two air inlets 101, which are distributed on the left and right sides of the top of the inner pot 2 to improve the efficiency of steam discharge.

[0048] like Figure 1 , Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines that: the exhaust channel 10 is formed with a plurality of channel branches at the air inlet end, the number of the channel branches is consistent with the number of the air inlets 101, and an air inlet 101 is formed on each channel branch.

[0049] Among them, the discharge channel 10 is provided with multiple channel branches at the air inlet end, and each channel branch corresponds to an air inlet 101. The steam in the washing chamber 201 can enter the corresponding channel branch through the multiple air inlets 101, and finally gather together and be discharged. By setting multiple channel branches, the efficiency of steam discharge is accelerated and the drying time of the dishwasher is shortened.

[0050] like Figures 1 to 5 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the steam exhaust device also includes a valve assembly, the valve assembly is installed in the exhaust channel 10, the valve assembly is linked with the suction assembly 20, when the suction assembly 20 is turned on, the valve assembly conducts the exhaust channel 10; when the suction assembly 20 is closed, the valve assembly cuts off the exhaust channel 10.

[0051] Among them, a valve assembly for controlling the conduction or cutoff of the discharge channel 10 is arranged in the discharge channel 10, and the valve assembly can be linked with the suction assembly 20. When the suction assembly 20 is turned on, the valve assembly is in an open state, and steam can be discharged from the discharge channel 10; when the suction assembly 20 is turned on, the valve assembly is in a closed state, so as to prevent the steam from being discharged from the discharge channel 10 to the outside during the high-temperature cleaning process of the dishwasher, resulting in too low a temperature in the washing chamber 201 and poor high-temperature cleaning effect. Among them, the valve assembly can be an electric valve or a pneumatic valve. Exemplarily, the valve assembly is an electric valve, and the electric valve and the suction assembly 20 are respectively connected to the control device of the dishwasher. When the control device receives the instruction of the suction assembly 20 to work, it controls the electric valve to open.

[0052] like Figures 1 to 5 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the air inlet 101 , the valve assembly, the suction assembly 20 and the air outlet 102 are sequentially distributed on the discharge channel 10 .

[0053] Among them, the air inlet 101, the valve assembly, the suction assembly 20 and the exhaust port 102 are distributed in sequence on the discharge channel 10. When the suction assembly 20 is closed, the valve assembly can block the high-temperature steam from flowing into the suction assembly 20, thereby reducing the damage to the suction assembly 20 caused by the high-temperature steam.

[0054] like Figures 1 to 5As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: the valve assembly includes a baffle 31, which is rotatably disposed in the discharge channel 10 to form at least a first position and a second position; when the suction assembly 20 is closed, the baffle 31 is in the first position; when the suction assembly 20 is opened, the baffle 31 rotates from the first position to the second position.

[0055] A rotatable baffle 31 is provided in the discharge channel 10. When the suction assembly 20 is in a closed state, the baffle 31 is located at a first position, and the baffle 31 can prevent high-temperature steam from being discharged from the discharge channel 10. When the suction assembly 20 is in an open state, under the suction force generated by the suction assembly 20, the baffle 31 rotates from the first position to the second position, and at this time, the steam can be discharged from the discharge channel 10 to the outside along the suction direction.

[0056] like Figures 2 to 5 As shown, in addition to the features of the above-mentioned embodiments, this embodiment is further defined as follows: a blocking block 111 is formed in the exhaust channel, the blocking block 111 is located between the air inlet 101 and the baffle 31, and when the baffle 31 is in the first position, the projection of the blocking block 111 on the baffle 31 is located at the bottom of the baffle 31 and lower than the rotation point of the baffle 31.

[0057] Among them, the exhaust channel is provided with a blocking block 111 between the air inlet 101 and the baffle 31. The blocking block 111 is located below the baffle 31 and below the rotation point. Since the density of steam is smaller than that of air, steam will gather above the channel when it enters the exhaust channel 10. If the lower part of the baffle 31 is not blocked by the blocking block 111, the steam will continuously impact the upper part of the baffle 31, which will easily cause the baffle 31 to rotate, resulting in leakage in the exhaust channel 10 when the suction component 20 is closed. Specifically, when the suction component 20 is turned on, since the direction of the suction force is from the air inlet 101 to the baffle 31, the baffle 31 is subjected to the unbalanced force on the upper and lower sides of the baffle 31 under the action of the suction force of the suction component 20 and the impact of steam, and the baffle 31 is easily deflected, causing the baffle 31 to rotate from the first position to the second position, thereby making the exhaust channel 10 conductive.

[0058] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the exhaust ports 102 are distributed on the side walls of the inner container 2 .

[0059] The exhaust port 102 of the discharge channel 10 is distributed on the side wall of the inner tank 2 to prevent the steam discharged from the exhaust port 102 from blowing directly toward the user when the user operates in front of the dishwasher, thereby preventing burns.

[0060] like Figure 1As shown, in addition to the features of the above embodiments, the present embodiment further defines that: the discharge channel 10 can be divided into a first channel 11 and a second channel 12, the first channels 11 are respectively at the top of the inner tank 2, and the second channels 12 are distributed on the side wall of the inner tank 2, the connection between the first channel 11 and the second channel 12 is an arc-shaped design, the suction assembly 20 is installed in the first channel 11, and the air outlet of the suction channel is close to the connection between the first channel 11 and the second channel 12.

[0061] Among them, the second channel 12 in the discharge channel 10 is distributed on the side wall of the inner tank 2, the connection between the first channel 11 and the second channel 12 is an arc-shaped design, and the suction component 20 is installed in the first channel 11 and close to the connection, so that the liquid water condensed at the air outlet of the suction component 20 can slide along the arc-shaped channel under the action of its own gravity, thereby avoiding long-term water accumulation in the suction component 20, causing bacterial growth or affecting the normal operation of electronic components in the suction component 20.

[0062] In addition to the features of the above-mentioned embodiments, the present embodiment further defines that: the steam exhaust device also includes a filter assembly, the filter assembly is arranged on the inner tank 2 and is located at the air inlet 101, and the washing chamber 201, the filter assembly and the air inlet 101 are connected in sequence.

[0063] The inner tank 2 is provided with a filter assembly at the air inlet 101 in the washing chamber 201, which can prevent the residual food from entering the discharge channel 10 during the steam discharge process of the washing chamber 201, which is not only troublesome to clean, but also easy to block the discharge channel 10 and damage the suction assembly 20. Exemplarily, the filter assembly is a barrel-shaped shell structure, and at least a first through hole and a second through hole are opened on the filter assembly, wherein the second through hole allows the residual food with a larger volume such as rice grains to enter the filter assembly for collection, and the first through hole only allows steam to pass through and enter the discharge channel 10.

[0064] 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.

[0065] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present utility model patent shall be subject to the attached claims.
