Description

Steam oven convenient for water replacement

Technical Field

The utility model belongs to the technical field of domestic oven, especially, relate to a steam oven of conveniently trading water.

Background

With the improvement of living standard, various food processing machines suitable for household use, such as electric ovens and electric steamers, are emerging. Although these food processors bring convenience to people's lives, they have a problem that household appliances in kitchens are more and more, and most of households have a small kitchen space, so that it is troublesome to store and store these numerous household appliances. Therefore, people try to design and manufacture multifunctional food processing machines, and one device can have more functions as much as possible, so that the number of the devices can be reduced, and meanwhile, the use requirements of different occasions can be met.

Baking is known as a popular cooking method, and steaming is the favorite of health preserving people. Therefore, people invent a steam oven which adds a steaming function on the basis of the existing electric oven, namely, the steam oven has the double functions of the electric oven and the electric steamer.

The existing steam oven usually comprises a box body with a working cavity inside, the front side of the working cavity is open, a box door capable of being turned over up and down is arranged at the opening of the box body, and an upper electric heating pipe and a lower electric heating pipe are arranged in the box body, so that food can be baked in an all-dimensional mode. At the same time, the water-saving device also comprises a steam generator and a corresponding water tank, and a water pump connected between the steam generator and the water tank.

When the food needs to be baked, the controller enables the upper electric heating pipe and the lower electric heating pipe to be electrified and heated, and then the food in the box body can be baked. When the function of steaming needs to be started, the controller starts the steam generator firstly, so that the steam generator is heated rapidly, then the water pump is started, water in the water tank is conveyed to the steam generator, and the water is instantly vaporized by the high temperature of the steam generator to form steam and is sprayed to food, so that the food is steamed.

Usually, one would place a functional chamber on the housing, separate from the working chamber, and place a controller or the like in the functional chamber. Correspondingly, a water tank for storing water is arranged in the functional cavity.

However, the existing steam oven has the following defects: firstly, the function intracavity can set up the slide rail along fore-and-aft direction usually, and water tank sliding connection is on the slide rail to be connected with the water pump through flexible pipeline, set up the location structure of water tank simultaneously in the function intracavity. When water needs to be added into the water tank, a user needs to open the tank door firstly, then releases the locking of the positioning structure on the water tank, and then pulls out the water tank, and at the moment, water can be added into the water tank by using tools such as a kettle and the like; after the water is added, the water tank is pushed back into the functional cavity, and the water tank is positioned by the positioning structure. This causes the complicated structure of the water tank and the inconvenience of manufacture and assembly, and the oven is liable to have problems such as the shaking and displacement of the water tank during storage and transportation. On the other hand, in order to keep the water stored in the water tank fresh and sanitary, when the steam oven is used once, the residual water in the water tank needs to be poured out, and the water tank of the existing steam oven is connected to the sliding rail in the functional cavity in a sliding manner, so that for a user, the water tank needs to be taken and placed from the functional cavity, the problem that the residual water is continuously used when the water tank is used is easy to occur, and the sanitary safety of food after cooking is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a conveniently trade steam oven of water, can convenience of customers emit remaining deposit water in the water tank to ensure the fresh health of water storage in the water tank, avoid influencing the food hygiene after the culinary art because of the long-time water storage of water tank.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a steam oven of conveniently trading water, includes box, lower side and the box that has the working chamber and rotates chamber door, water pump be connected, steam generator and the water tank of being connected with the water pump respectively through connecting line, is equipped with the control unit including the control button on the chamber door, the chamber door includes door frame support, covers the top layer in the inside and outside both sides of door frame support, the water tank sets up the intermediate position at door frame support, is equipped with the water injection seat of the water inlet intercommunication through water injection pipeline and water tank that can one-way switch on door frame support, is equipped with the waste water box of connection on the box in the below of chamber door, is equipped with the play water stand through pipeline and water tank bottom intercommunication at door frame support's downside, goes out the water stand and includes towards the control valve of waste.

First, the utility model discloses with the door frame support intermediate position of water tank setting between the inside and outside both sides top layer of chamber door to make chamber door and water tank form the overall structure of a concatenation formula, make things convenient for the manufacturing and the assembly of water tank greatly. In addition, when a user needs to add water into the water tank, water can be directly injected into the water tank through a water injection pipeline communicated with a water inlet of the water tank only by directly injecting water into the water injection seat by using tools such as a water kettle, and therefore the water tank is greatly convenient to add water.

Because the water tank is arranged in the box door, the size of the functional cavity can be fully reduced, the size of the box body is further reduced, and the placement of the steam oven in a kitchen space is facilitated.

It can be understood that, because the area of chamber door is great, consequently, with the water tank setting inside the chamber door, not only can ensure that the water tank has sufficient effective volume, but also can make full use of the inner space of chamber door to promote the thermal-insulated effect of chamber door, avoid the chamber door surface of high temperature to cause the injury to the user.

Particularly, the utility model discloses be equipped with the waste water box that is located the chamber door below on the box, be equipped with the play water stand that communicates through pipeline and water tank bottom at the downside of door frame support. Therefore, after the user finishes the one-time use of the steam oven, the residual stored water in the water tank can be released into the waste water box through the water outlet seat; when the steam oven is used continuously next time, fresh water can be injected into the water tank again, so that the freshness and sanitation of the steam water are ensured, and the improvement of the sanitation and safety of food cooking is facilitated.

In addition, when the steaming function of the steam oven is finished, certain condensed water is generated inside the oven door and the working cavity of the oven body. At the moment, the condensed water on the inner side of the box door can naturally flow downwards to enter the wastewater box, and the condensed water in the working cavity can flow to the bottom wall of the working cavity and flow forwards to flow out from the edge of the opening to enter the wastewater box; when the user is with clean box inside work chamber such as wet cloth, can conveniently with a small amount of dirty water propelling movement of rag with clean formation to box front side open-ended lower border department, and then flow into in the waste water box through the opening to make things convenient for the subsequent maintenance and the cleanness of steam oven, be favorable to keeping the clean and tidy of kitchen.

It can be understood that the water outlet seat is communicated with the bottom of the water tank through a pipeline, so that the residual water in the water tank can be completely drained, the drain pipe which is arranged on the water outlet seat and is opened towards the upper side of the waste water box can accurately and reliably flow into the waste water box through the residual water drained from the water outlet seat, and the control valve can conveniently control the on-off of the drain pipe so as to conveniently control the drainage and the water addition of the water tank.

Preferably, the control valve comprises a rotating member which is arranged at the lower side of the water outlet seat and is provided with an opening position and a blocking position, and the rotating member comprises a blocking surface which is away from the opening of the drain pipe when the rotating member is positioned at the opening position; when the rotating part rotates forwards to the blocking position, the blocking surface is tightly attached to the opening of the drain pipe.

It is known that a waste water box is arranged below the drain pipe, and the steam oven is not used for a long time, so that a control valve for controlling the on-off of the drain pipe is not required to have high tightness. That is, even if a slight amount of the stored water seeps out of the control valve and flows into the waste water tank, it does not adversely affect the steam oven.

Therefore, the control valve of the utility model comprises a rotating part with a plugging surface. When the residual water in the water tank needs to be drained, a user can enable the rotating piece to rotate to the opening position, and the blocking surface of the rotating piece leaves the opening of the drain pipe at the moment, so that the drain pipe is in a conduction state, and the residual water in the water tank can completely flow into the waste water box; when water is required to be added into the water tank, a user can enable the rotating piece to rotate to the blocking position, the blocking surface of the rotating piece is tightly attached to the opening of the water discharging pipe, and therefore the water discharging pipe is in a cut-off state, and further the water storage in the water tank can be prevented from flowing outwards to enter the waste water box.

That is to say, through the break-make of the rotation piece control drain pipe, both convenience of customers' operation uses, can show the structure of simplifying control valve again, under the prerequisite that satisfies the necessary sealed effect of control valve, reduces manufacturing, the assembly cost of control valve.

Preferably, a sealing ring is embedded in the annular end face of the drain pipe, and the sealing face is tightly attached to the sealing ring when the rotating member is located at the sealing position.

The sealing ring can obviously improve the sealing effect between the plugging surface and the drain pipe. Particularly, the sealing ring embedded on the annular end surface of the drain pipe is convenient to replace and maintain, so that the control valve can always keep a good sealing effect on the drain pipe.

Preferably, it includes the mounting of rigid coupling on the door frame support to go out the water stand, and the drain pipe setting is at the mounting downside, rotate the piece setting at the mounting downside, rotate one end upside and be equipped with the shutoff face rotates the piece other end and is operating handle.

The user can conveniently control the rotation of the rotating part by stirring the operating handle so as to enable the blocking surface on the rotating part to be attached to and block the opening of the drain pipe or to be away from the opening of the drain pipe to conduct the drain pipe.

It can be understood that the fixed member and the rotating member can be manufactured by injection molding, and the drain pipe can be integrally formed with the fixed member, so that the manufacturing is convenient, and the connection reliability and good sealing performance can be ensured.

Preferably, the upper side of the fixing part is provided with a notch, a water pipe joint communicated with the water discharge pipe is arranged in the notch, and a pipeline communicated with the bottom of the water tank is connected to the water pipe joint.

The water pipe joint communicated with the water discharge pipe is convenient for the fixing piece to be communicated with the water tank through a pipeline. Because the water pipe joint is arranged in the concave opening on the upper side of the fixing piece, the water pipe joint can be effectively shielded, and the water pipe joint is prevented from being broken at the connecting part of the fixing piece.

Preferably, the blocking surface is arranged in a manner of inclining from high to low in a tangential direction of a forward rotation track with a rotation center of the rotating member as a center, and an end surface of the water discharge pipe has an inclination matched with the blocking surface.

The utility model discloses a shutoff face is by high to low slope setting on the tangential direction of the forward rotation orbit that uses the rotation center of rotating the piece as the centre of a circle, that is to say, the shutoff face at the forward rotation direction front side of rotating the piece is less than the shutoff face of rear side. Therefore, when the rotating piece rotates forwards to the blocking position, the blocking surface with the lower front side can conveniently enter the lower side of the drain pipe; when the rotating piece rotates to a position, the inclined plugging surface can be tightly attached to the end face of the drain pipe which is inclined as well. Particularly, the rotating part can be ensured to be in a self-locking mode with the end face of the drain pipe when the rotating part is in the blocking position by reasonably setting the inclination angle of the blocking face, and the rotating part is reliably positioned in the blocking position.

Preferably, the sealing ring is 0.5mm-2mm higher than the end face of the drain pipe.

By reasonably setting the height difference between the sealing ring and the end face of the drain pipe, the rotating piece can be conveniently and easily rotated to the blocking position on the premise of ensuring the good sealing effect of the rotating piece on the drain pipe, and the rotating piece can be reliably positioned at the blocking position. When the height difference between the sealing ring and the end surface of the drain pipe is less than 0.5mm, the sealing effect of the rotating piece on the drain pipe is influenced, and the reliability of the rotating piece when being positioned at the blocking position is reduced; when the difference in height between sealing ring and the drain pipe terminal surface is greater than 2mm, can cause the excessive extrusion of shutoff face to the sealing ring, be the rotation piece on the one hand and be difficult to accurately rotate to the shutoff position, on the other hand can be that the sealing ring receives the shearing and damages to the shutoff face produces the slope easily when receiving the elasticity effect of sealing ring, and then influences the sealed effect of shutoff face.

Preferably, the inner side of the water inlet of the water tank is provided with an elastic sheet, the elastic sheet is provided with a positioning bulge, and the positioning bulge is embedded on the side wall of the water tank.

The elastic sheet can be made of food-grade silica gel, so that the elastic sheet has certain elasticity, and the elastic sheet is positioned on the inner side wall of the water tank through the positioning bulge embedded on the side wall of the water tank, so that the elastic sheet forms a cantilever beam structure, and the manufacturing and the assembly of the one-way valve are facilitated. When the user adds water in toward the water tank through the seat of annotating water, rivers can break away the flexure strip and get into in the water tank after passing through the water inlet, and the impulsive force of rivers and the gravity combined action of flexure strip self make the flexure strip keep away from the bellied hanging end of location and produce the slope and leave the water tank inside wall this moment.

When the height of the box door and the water injection seat is reduced, the elastic sheet is extruded from the inside of the water storage in the water tank, so that the elastic sheet is attached to the inner side wall of the water tank and blocks the water inlet, and the water storage in the water tank can be prevented from overflowing outwards through the water inlet.

It can be understood that we can make the elastic sheet have a suitable elasticity through rationally setting the thickness, the material isoparametric of elastic sheet to ensure that the rivers that get into from the water injection seat can break the elastic sheet and get into in the water tank, on the contrary, when the user stopped the water injection, the elastic sheet then can lean on the water tank inside wall and shutoff water inlet under the effect of self elasticity. When the box door is opened to enable the water tank to topple, the pressure of the stored water enables the elastic sheet to reliably press against the inner side wall of the water tank, and therefore the reliability of reverse stopping of the one-way valve is guaranteed.

As preferred, the lateral wall of water tank is equipped with fixing hole, the location arch includes the spliced pole with flexure strip body coupling, sets up the toper joint that radially expands outward at spliced pole tip, and the spliced pole adaptation is in fixing hole, and the joint pastes and leans on the water tank lateral wall.

When the check valve needs to be installed, the connecting column can penetrate through the fixing through hole in the side wall of the water tank from inside to outside, and the conical clamping joint with a small head and a large back is beneficial to penetrating through the fixing through hole. When the connecting column is installed in place in the fixing through hole, the conical clamping joint which expands outwards in the radial direction can be elastically reset and is attached to the outer side wall of the water tank, so that the connecting column is prevented from falling off from the fixing through hole.

It should be noted that, we can make the connection column and the fixed through hole form an interference fit, so as to generate a certain friction force between the connection column and the fixed through hole with elasticity, and effectively avoid the elastic sheet installed on the inner side wall of the water tank from rotating by itself.

Preferably, one side of the elastic sheet, which is far away from the positioning protrusion, is provided with a mounting hole extending into the positioning protrusion.

It will be appreciated that the positioning projections formed integrally with the elastic sheet have a certain elasticity. Therefore, when we squeeze the positioning protrusion into the mounting through hole or the fixing hole of the top wall of the tank, the positioning protrusion is bent and deformed, thereby causing difficulty in mounting. The utility model discloses keep away from protruding one side in location at the flexure strip and be equipped with the mounting hole that extends to in the location arch, like this, when installing the flexure strip, available slender rod inserts in the mounting hole to greatly increase the bellied rigidity in location, convenient location arch interference fit is to in installation through-hole or the fixed orifices.

Therefore, the utility model discloses following beneficial effect has: the residual stored water in the water tank can be discharged by a user conveniently, so that the freshness and the sanitation of the stored water in the water tank are ensured, and the food sanitation after cooking is prevented from being influenced by the long-time stored water in the water tank.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 and 2, a steam oven convenient for water exchange comprises a box body 1, wherein the box body comprises a working chamber 11 with an open front side and a functional chamber for installing functional components, a box door 2 covering the working chamber is arranged on the front side of the box body, and the lower side of the box door is rotatably connected with the box body, so that the box door can be rotated to be in a substantially horizontal state when opened. The upper part and the lower part in the working cavity are respectively provided with an electric heating pipe so as to be convenient for baking the food in the working cavity. And the functional components (not shown in the figure) comprise a steam generator, a water pump, a temperature control element for controlling the temperature in the working chamber and the like which are arranged in the functional chamber. In addition, the steam oven also comprises a water tank 3 for storing water and a control part 4 with a control key, wherein the water inlet of the water pump is connected with the water tank through a connecting pipeline, the water outlet of the water pump is connected with the steam generator through a connecting pipeline, and the control part can set and control the working procedure of the steam oven.

When food needs to be baked, the food can be placed into the working cavity, the steam oven is arranged in a baking state through the control key, the baking program can be started after corresponding parameters such as temperature, time and the like are set, and the electric heating pipe at the moment is electrified to generate heat, so that the food can be baked in all directions.

When the dish is steamed by cooking, the material can be put into the working cavity, then the function of steaming is started, the steam generator at the moment is electrified to heat up quickly, then the water pump is started to convey the stored water in the water tank to the steam generator, and the water is quickly vaporized to form steam during the steam generator. When the water pump makes water continuously drop on the steam generator, continuous steam can be formed, thereby cooking food.

Since the steam oven is the prior art, the features and structures of the prior art, such as the steam generator, the control part, and the water pump, are not described in this embodiment.

In order to facilitate the assembly and manufacture of the box door, the box door is of a splicing structure. Specifically, the box door comprises a door frame bracket 22 in a shape like a Chinese character kou and a surface layer 21 covering the inner side and the outer side of the door frame bracket, and the water tank is arranged in the middle of the door frame bracket. That is to say, the chamber door is the sandwich structure that has the water tank inside that the equipment of interior outer skin formed, under the prerequisite of guaranteeing the effective volume of water tank, can make full use of the inner space of chamber door to promote the thermal-insulated effect of chamber door effectively.

It will be appreciated that the tank may be a flat separate member or may be formed integrally with one of the skins to form a unit, and that the tank door may be assembled by simply locating the tank in the centre of the doorframe bracket and then assembling the two units together, thereby greatly simplifying the manufacture and assembly of the door, and particularly the tank.

It is known that, when the steam oven works, the temperature rise of the part of the box door corresponding to the opening of the working cavity of the box body is the highest, and water has larger specific heat capacity. Therefore, the area of the water tank can completely cover the opening of the working cavity, so that the water stored in the water tank can fully absorb the heat of the working cavity, the heat in the box body is prevented from being transferred to the outer surface of the box door, the outer surface of the box door can be always at a proper temperature, and the safety of the steam oven in use is improved.

Because the water tank is arranged in the box door, the size of the functional cavity can be fully reduced, the whole size of the box body is further reduced, and the placement of the steam oven in a kitchen space is facilitated.

Certainly, the temperature of the stored water in the water tank rises after the stored water absorbs the heat of the working cavity, and when the stored water in the water tank is conveyed to the steam generator, the stored water is favorable for vaporization of the water, so that the energy consumption of the steam generator is reduced.

It should be noted that the functional cavity can be arranged at the rear part of the waste water box below the box body or at the rear part of the box body, so as to reduce the external dimension of the front surface of the box body as much as possible. Of course, the functional component should be located in the functional cavity, so that the functional component is effectively isolated from the high-temperature working cavity.

In order to facilitate operation, the control part can be arranged at the right side of the door frame support corresponding to the function cavity or at the lower side of the door frame support, specifically, the control part comprises a display screen and a touch control key, so that the working program of the steam oven is displayed and controlled through the outer surface of the touch oven door, and the attractiveness of the steam oven is improved.

In this embodiment, the side of the working chamber of the box body where the working chamber is opened is referred to as a front side or an outer side, and a rear side or an inner side and left and right sides are defined accordingly.

As shown in figure 3, a water injection seat 5 can be arranged on the left side of the doorframe bracket and is exposed out of the left side of the case door, and the water injection seat is communicated with a water inlet of the water tank through a water injection pipeline. When a user needs to add water into the water tank, water can be injected into the water injection seat on the side edge of the tank door by using a tool such as a kettle, and the water in the water injection seat can enter the water tank through a water injection pipeline communicated with the water inlet of the water tank.

It should be noted that the door of the steam oven can be entirely covered on the front side of the box body, so that the side edge of the door and the water injection seat are exposed outside the box body. When a user needs to fill water into the water tank, water can be filled into the water tank only by directly filling water into the water filling seat exposed on the side edge of the box door by using a tool such as a kettle, so that the water can be greatly conveniently filled into the water tank.

In addition, a one-way valve capable of enabling the water inlet to be conducted from outside to inside can be arranged in the water tank, when a user opens the box door and the position of the water injection seat on the side edge of the box door is lowered, the one-way valve can effectively prevent stored water in the water tank from flowing out in the opposite direction through the water inlet, and therefore normal use of the steam oven is guaranteed.

Preferably, as shown in fig. 4, the check valve includes an elastic sheet 6 disposed at a position corresponding to the water inlet on the inner side wall of the water tank, and the elastic sheet may be made of food grade silica gel, so as to ensure the sanitary safety of the elastic sheet, and to make the elastic sheet have good fatigue resistance and maintain sufficient elasticity all the time. The downside of flexure strip sets up integrative location arch 61, and the location arch inlays to be established on the lateral wall of water tank to make the flexure strip constitute the cantilever beam structure, and make things convenient for the installation of flexure strip in the water tank.

When the user adds water into the water tank through the water injection seat, rivers can break open the free end of flexure strip and get into in the water tank behind the water inlet, and the impulsive force of rivers and the gravity combined action of flexure strip self this moment make the free end of flexure strip produce the slope and leave the water tank inside wall.

When the height of the box door and the water injection seat is reduced, the elastic sheet is extruded from the inside by the elastic force of the elastic sheet and the water storage in the water tank, so that the elastic sheet is tightly attached to the inner side wall of the water tank and blocks the water inlet, and the water storage in the water tank can be prevented from overflowing outwards through the water inlet.

Furthermore, we can also set up fixed through hole 31 at the lateral wall of water tank, and the location arch includes spliced pole 611 with flexure strip body coupling, sets up the toper joint 612 at the spliced pole tip, and the spliced pole adaptation is in fixed through hole, and the rear end of toper joint is greater than the spliced pole to make the rear end face of joint paste and lean on the water tank lateral wall, so that the flexure strip reliably fixes a position on the water tank lateral wall, avoid the spliced pole to drop from the fixed through hole by oneself.

It can be understood that the connecting column and the fixing through hole can form an interference fit, so that a certain friction force is generated between the connecting column with elasticity and the fixing through hole, and the elastic sheet arranged on the inner side wall of the water tank is effectively prevented from rotating by itself.

When the elastic sheet needs to be installed, the conical clamping joint with a small head and a large back can conveniently penetrate through the fixing through hole from inside to outside. When the connecting column is installed in place in the fixing through hole, the conical clamping joint which expands outwards in the radial direction can be elastically reset and is attached to the top wall of the outer side of the water tank, so that the connecting column is prevented from falling off from the fixing through hole.

Furthermore, a mounting hole 613 extending into the positioning protrusion may be formed on the side of the elastic sheet away from the positioning protrusion. Like this, when the installation flexure strip, can insert in the mounting hole with a slender pole to greatly increase the bellied rigidity of location, make things convenient for protruding interference fit of location to the mounting hole or the fixed orifices of water tank lateral wall.

In addition, we can set up waste water box 13 in the lower part of box, and the width of waste water box matches with the width of box, and the front side of waste water box extends forward and exposes the box, and until waste water box and chamber door front side top layer flush, the waste water box upper portion that exposes the box sets up the opening that corresponds with chamber door downside limit. Thus, the condensed water in the tank body, especially the inner side of the tank door, can naturally flow downwards into the waste water tank. When the user is with clean box inside work chamber such as wet cloth, can conveniently with a small amount of dirty water propelling movement of rag with clean formation to box front side open-ended lower border department, and then flow into in the waste water box through the opening to make things convenient for the subsequent maintenance and the cleanness of steam oven, be favorable to keeping the clean and tidy of kitchen.

In order to facilitate the drainage of water stored in the water tank, as shown in fig. 3, a water outlet seat 7 can be arranged at the lower part of the doorframe bracket and is communicated with the bottom of the water tank through a connecting pipeline. Preferably, the water outlet seat comprises a water outlet pipe 71 which is opened towards the upper side of the waste water box and a control valve for controlling the on-off of the water outlet pipe.

When the steam oven is used and residual water in the water tank needs to be drained, a user can open the box door partially to enable the box door to be inclined, then the control valve is opened to enable the drain pipe to be communicated, and stored water in the water tank can be drained into the waste water box through the drain pipe under the action of self gravity. When the steam oven is reused, the user may close the control valve and then refill the water tank with clean water to ensure the cleanliness and hygiene of the cooked food. Because the position of the water outlet seat is lower than the bottom of the water tank, residual water in the water tank can be discharged outwards through the drain pipe, and therefore water accumulation at the bottom of the water tank is avoided. The drain pipe should be connected to the bottom of the water tank through a connecting pipe.

Preferably, as shown in fig. 5, the water outlet seat comprises a fixed member 72 fixed to the doorframe bracket, the water outlet pipe is disposed at the lower side of the fixed member, a vertical rotating pin is disposed at the lower side of the fixed member, the control valve comprises an L-shaped rotating member 73, the middle turning point of the rotating member is rotatably connected to the rotating pin, so that the rotating member can rotate from the open position to the blocking position in the horizontal direction, the upper surface of one end of the rotating member is a blocking surface 731, and the other end of the rotating member is an operating handle 732.

When a user needs to empty the residual water in the water tank, the operating handle can be pulled to enable the rotating piece to rotate to the opening position, the blocking surface of the rotating piece leaves the opening of the water discharging pipe at the moment, and therefore the water discharging pipe is in a conducting state, and the residual water in the water tank can completely flow into the waste water box through the water discharging pipe. When the user need add water in the water tank, can stir operating handle, make and rotate a piece and rotate to the shutoff position, the shutoff face that rotates this moment closely pastes and leans on the drain pipe opening to make the drain pipe be in the off-state, and then can prevent the water storage in the water tank outwards to flow and get into in the waste water box.

That is to say, through the break-make of the rotation piece control drain pipe, both convenience of customers' operation uses, can show the structure of simplifying control valve again, under the prerequisite that satisfies the necessary sealed effect of control valve, reduces manufacturing, the assembly cost of control valve.

It can be understood that the fixed member and the rotating member can be manufactured by injection molding, and the drain pipe can be integrally formed with the fixed member, so that the manufacturing is convenient, and the connection reliability and good sealing performance can be ensured.

Preferably, set up annular seal groove 711 on the ring face of drain pipe, at the embedded sealing ring 74 that is equipped with higher drain pipe terminal surface of seal groove, when rotating the piece and rotating to the shutoff position, the shutoff face closely pastes and leans on the sealing ring to promote the sealed effect between shutoff face and the drain pipe, and inlay the convenient change of sealing ring of establishing on the ring face of drain pipe and maintain, thereby be favorable to making the control valve remain good sealed effect throughout to the drain pipe.

Further, a notch 721 is formed at the upper side of the fixing member corresponding to the drain pipe, a water pipe joint 75 coaxially communicated with the drain pipe is formed in the notch, and a pipeline communicated with the bottom of the water tank is connected to the water pipe joint, so that the water tank is communicated with the drain pipe. Because the water pipe joint is arranged in the concave opening on the upper side of the fixing piece, the water pipe joint can be effectively shielded, and the water pipe joint is prevented from being broken at the connecting part of the fixing piece.

In order to facilitate the rotating piece to rotate back and forth between the opening position and the blocking position, the blocking surface can be obliquely arranged from high to low in the tangential direction of a positive rotating track taking the rotating center of the rotating piece as a circle center, and the end face of the drainage pipe has an inclination matched with the blocking surface. For example, if the forward rotation of the rotating member is clockwise, the forward rotation locus is a clockwise circle, and accordingly, the tangential direction of the forward rotation locus means a direction toward the clockwise side in the tangential line of the rotation locus, and the front side of the blocking surface in the tangential direction of the forward rotation locus is lower than the rear side and is wedge-shaped.

When the rotating part rotates forwards to the blocking position, the blocking surface with the lower front side can conveniently enter the lower side of the drain pipe; when the rotating piece rotates to a position, the inclined plugging surface can be tightly attached to the end face of the drain pipe which is inclined as well. Preferably, the inclined angle of the blocking surface can be kept between 3 degrees and 5 degrees, so that the blocking surface can form self-locking with the end surface of the drain pipe when the rotating piece is in the blocking position, and the rotating piece is reliably positioned in the blocking position.

Furthermore, the height difference between the sealing ring and the end face of the drain pipe can be controlled to be 0.5mm-2mm, the rotating piece can be conveniently and easily rotated to the blocking position on the premise that the rotating piece has a good sealing effect on the drain pipe, and the rotating piece can be reliably positioned and self-locked at the blocking position.

It is understood that various changes and modifications other than those described in the preferred embodiments described above may be made by those skilled in the art without departing from the spirit of the invention, and the scope of the invention is defined by the appended claims.
