Steam oven convenient for water adding

Technical Field

The utility model belongs to the technical field of domestic oven, especially, relate to a convenient watered steam oven.

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, a functional cavity separated from the working cavity is arranged on the right side of the box body, and a controller and other components are arranged in the functional cavity. Correspondingly, a water tank for storing water is arranged in the functional cavity.

However, the existing steam oven has the following defects: firstly, a slide rail along the front-back direction is arranged in the functional cavity, the water tank is connected to the slide rail in a sliding mode and is connected with the water pump through a flexible pipeline, and meanwhile a positioning structure of the water tank is arranged in the functional cavity. 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, because the chamber door rotates about and connects on the box, consequently, the user need open the chamber door completely and just can pull out the water tank, need reposition the water tank after adding water to cause the inconvenience of adding water.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a make things convenient for watered steam oven, but the user adds water toward the water tank in, is favorable to simplifying the assembly and the manufacturing of water tank simultaneously to the overall dimension of reducible box reduces the temperature rise of chamber door.

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

the utility model provides a convenient watered steam oven, is equipped with the chamber door including box, functional unit and the water tank that has the working chamber, the box front side, functional unit includes water pump, steam generator, and the water pump is connected with water tank, steam generator respectively through connecting tube, the chamber door includes the top layer of inside and outside both sides at least, intermediate position between the extexine including the water tank setting is equipped with the water injection seat through the water inlet intercommunication of water injection pipeline and water tank on a chamber door side, is equipped with the check valve that can make water inlet outside-in switch on in the water tank.

First, the utility model discloses with the 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 particular, the door of the steam oven covers the front side of the cabinet, i.e. the side edges of the door are exposed outside the cabinet. 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 on the side edge of the tank door through a tool such as a water kettle, so that the water tank is greatly convenient to add water.

Particularly, the one-way valve which can lead the water inlet to be conducted from outside to inside is arranged in the water tank, so that the stored water in the water tank is effectively prevented from overflowing outwards on the premise of ensuring the normal water injection into 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 check valve can effectively prevent the stored water in the water tank from flowing outwards and reversely through the water inlet, and further the normal use of the steam oven is ensured.

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 the box door is large, the water tank is arranged inside the box door, so that the water tank can be ensured to have enough effective volume, and the inner space of the box door can be fully utilized. The water tank has enough area, so that the water tank can effectively cover the opening of the working chamber, the heat insulation effect of the box door is improved, and the damage to a user caused by the surface of the box door with high temperature is avoided.

Preferably, the check valve comprises an elastic sheet attached to the inner side of the water inlet of the water tank, and a positioning bulge is arranged on the elastic sheet and embedded in 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 adds the gravity combined action of flexure strip self this moment, makes the flexure strip keep away from protruding one side of location and produces 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 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, the lateral wall of the box door is provided with a water injection through hole, the water injection seat comprises a fixed box body which is arranged in the box door and close to the water injection through hole, one side of the fixed box body is provided with a pull opening connected with the water injection through hole, the lower part of the other side of the fixed box body, which is opposite to the pull opening, is connected with a water injection pipeline, and the pull opening is internally and slidably connected with a pull box body with an upper.

The utility model discloses a water injection seat includes that one fixes fixed box body, the gliding pull box body in the pull opening of fixed box body on the chamber door inside wall. Thus, when water is not needed to be injected, the drawing box body is positioned in the drawing opening of the fixed box body, so that the appearance of the box door is not influenced, the interference caused when the box door is opened is avoided, and the water injection seat is kept clean and sanitary. When water is injected into the water tank, the drawing box body can be pulled out in the lateral direction, at the moment, a user can inject water into an upper opening of the drawing box body by using tools such as a kettle and the like, water entering the drawing box body enters the fixed box body, and then flows into the water tank through a water injection pipeline on the other side of the fixed box body. When the water injection is finished, the user only needs to push the drawing box body back into the fixed box body again to ensure that the side edge of the box door keeps flat and beautiful.

It can be understood that, because the box door is a splicing structure at least comprising an inner side surface layer and an outer side surface layer, a fixed box body can be conveniently arranged inside the box door and connected with a water injection pipeline.

Preferably, a water outlet hole is formed in the lower portion of the side wall, close to the water injection pipeline, of the drawing box body, and a positioning structure for limiting the moving stroke of the drawing box body is arranged between the drawing box body and the fixed box body.

Because the inside wall lower part that the pull box body is close to the water injection pipeline is equipped with the apopore, that is to say, the pull box body has and encloses into annular lateral wall to be favorable to improving its intensity and rigidity, the water accessible that gets into the pull box body gets into the water injection pipeline fast with the apopore that the water injection pipeline is relative in, avoid effectively that the water in the pull box body outwards oozes through and the fit clearance between the fixed box body.

In addition, location structure can accurately prescribe the outward travel of removal of pull box body, avoids the excessive pull of pull box body and deviates from the water injection through-hole.

Preferably, the drawing box body comprises an outer side wall exposed out of the water injection through hole, and the upper part of the outer side wall inclines outwards, so that a handle fastening position is formed between the outer side wall of the drawing box body and the side wall of the box door.

Because the outer side wall upper portion of the drawing box body inclines outwards, namely, the outer side wall upper portion of the drawing box body is higher than the outer side surface of the box door, a hand buckling position suitable for a user to enter is formed between the outer side wall of the drawing box body and the side wall of the box door. When water is injected into the water tank, a user only needs to stretch fingers into the hand buckling position, the drawing box body can be conveniently moved outwards, and therefore water can be conveniently added into the water tank.

Preferably, the drawing box body comprises an outer side wall exposed out of the water injection through hole, and the side wall of the box door is positioned on the upper side of the water injection through hole and is inwards recessed, so that a handle buckling position is formed between the outer side wall of the drawing box body and the inwards recessed side wall of the box door.

In this scheme, we make the chamber door lateral wall be located water injection through-hole upside part inwards sunken, that is to say, the chamber door lateral surface that is located pull box body upper portion is less than the lateral wall of pull box body to form a knot hand position that is fit for the user to point the entering between the lateral wall of pull box body outer wall and the inside sunken lateral wall of chamber door. When water is injected into the water tank, a user only needs to stretch fingers into the hand buckling position, the drawing box body can be conveniently moved outwards, and therefore water can be conveniently added into the water tank. Especially, the outer side wall of the drawing box body in the scheme is generally kept flush with the outer side surface of the box body, so that the interference generated when the box door is opened and closed can be effectively avoided, and the appearance of the box door is favorably improved.

Preferably, the positioning structure comprises a sliding groove formed in the top wall of the fixed box body and a limiting bump arranged on the upper edge of the side wall of the drawing box body and far away from the water injection through hole, and the limiting bump is connected in the sliding groove in a sliding mode.

The limit lug which is connected in the sliding groove in a sliding way can accurately limit the moving stroke of the drawing box body. It can be understood that, the fixed box body that has the spout, the equal accessible injection moulding technology of the pull box body that has spacing lug makes, during the equipment, we only need to have the rear end downward sloping of spacing lug with the pull box body, then make the upside of pull box body rear end and spacing lug put into the pull opening of fixed box body, and make spacing lug card go into in the spout of fixed box body, then make the front end of pull box body rotate downwards, with the flat pull box body of pendulum, can impel the fixed box body with the pull box body this moment, in order to constitute the seat of watering, reuse screw will fix the box body in the top layer can. It should be noted that we can make the drawing opening of the drawing box body and the fixed box body have enough fit clearance in the height direction, so as to facilitate the rear end of the drawing box body to enter the drawing opening of the fixed box body.

Preferably, the lower side edge of the drawing opening is provided with a water retaining rib protruding upwards, and the lower side edge of the side wall of the drawing box body close to the water injection pipeline is provided with a water retaining rib protruding downwards.

Because pull open-ended downside edge and pull box body inner wall lower limb are equipped with the manger plate rib respectively, consequently, on the one hand, can show and reduce under the pull box body under the lateral wall and the fixed box body cooperation area between the lateral wall to be favorable to reducing the friction, on the other hand, the manger plate rib of pull opening part can prevent effectively that the water that oozes through the cooperation clearance between pull box body, the fixed box body outwards flows out the pull opening. That is to say, this manger plate rib can play a similar dam effect, when the user poured water into the pull box body in, even there was a trace water infiltration in the fit clearance between pull box body and the fixed box body, under the effect of self gravity, this part of water also can gather on the lower lateral wall of fixed box body, after receiving the blockking of the manger plate rib of pull opening part, inside backward flow to flow into in the water tank through the water injection pipeline in the fixed box body.

Preferably, the top wall and the bottom wall of the fixed box body are arranged in a downward inclined mode from outside to inside.

Because the diapire of fixed box body is from outer to interior downward sloping setting, that is to say, the lower lateral wall of fixed box body is the inclined plane of high interior low outward. Therefore, water seeping into the fit clearance between the drawing box body and the fixed box body can be effectively prevented from flowing out from the drawing opening. In particular, the top wall and the bottom wall of the stationary box remain at the same time arranged obliquely, that is to say the height of the stationary box in the vertical section can be kept uniform, so that the drawer box in the stationary box can be pulled out easily.

Therefore, the utility model discloses following beneficial effect has: the water tank can be filled with water by a user, the assembly and the manufacture of the water tank are facilitated to be simplified, the overall dimension of the tank body can be reduced, and the temperature rise of the tank door is reduced.

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 adding water comprises an oven body 1, wherein the oven body comprises a working chamber 11 with an open front side and a functional chamber for installing functional components, and a door 2 covering the working chamber is arranged on the front side of the oven body. 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 door includes inner and outer skins 21, and the tank is disposed intermediate the inner and outer skins. 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 at a position intermediate the inner and outer skins 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 and control, the control part can be arranged between the inner surface layer and the outer surface layer of the box door, and 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 box 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 a preferred scheme, a water injection seat 5 is arranged on the left side edge of the box door and 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. Of course, the lower side of the box door can be rotatably connected with the box body. Therefore, 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, and the like, so that the water can be greatly conveniently filled into the water tank.

When people overturn downwards and open the box door, the box door can be accurately and reliably positioned at the maximum opening position which is approximately horizontal under the action of self gravity, so that materials can be conveniently taken and placed in the box body, and the situation that the materials are prevented from being taken and placed due to random rotation of the box door is avoided.

Furthermore, a one-way valve 6 which can enable the water inlet to be communicated from outside to inside in a one-way mode can be arranged in the water tank. Like this, in the water accessible water injection pipeline entering water tank in the water injection seat, but the water storage in the water tank can't flow to the outside through the water injection pipeline, is guaranteeing to avoid the water storage in the water tank outwards to spill over under the prerequisite of normal water injection in the water tank effectively. When a user opens the box door to enable the box door to be approximately horizontal and the position of the water injection seat on the side edge of the box door is lowered, the check valve can effectively prevent stored water in the water tank from flowing outwards in a reverse direction through the water inlet, and therefore normal use of the steam oven is ensured.

Preferably, the check valve comprises an elastic sheet 61 made of food-grade silica gel, an integrated positioning bulge 62 is arranged at the lower part of the elastic sheet, and the positioning bulge is embedded on the side wall of the water tank, so that the elastic sheet is attached to the inner side of the water inlet of the water tank under the action of self elasticity, and the elastic sheet at the moment forms a cantilever beam structure.

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 through the water inlet, the flexure strip upper portion at this moment leaves the water tank inside wall and slope, the impulsive force of rivers and the combined action of flexure strip self gravity, the flexure strip upper portion production slope and leave the water tank inside wall, the water tank water inlet at this moment is in the switch-on state within the follow. That is, the torque for opening the elastic piece formed by the impact force of the water flow and the gravity of the elastic piece is larger than the torque for closing the elastic piece formed by the elastic force of the elastic piece.

When the box door is opened to enable the box door to be flat and the height of the water injection seat to be reduced, the impact force of water flow and the torque of the elastic sheet which is opened and formed by the gravity of the elastic sheet disappear, at the moment, the elastic force of the elastic sheet and the pressure combined action of the water storage in the water tank on the elastic sheet enable the elastic sheet to be tightly attached to the inner side wall of the water tank and block the water inlet, and therefore 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, the pressure of the stored water enables the elastic sheet to reliably press against the inner side wall of the water tank, so that the reliability of reverse stop of the one-way valve is ensured.

Further, we can set up fixing hole 32 at the lateral wall of water tank, and the location is protruding including the spliced pole 621 with flexure strip body coupling, set up the toper joint 622 at the spliced pole tip, and the spliced pole adaptation is in fixing 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 fixing hole by oneself.

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.

In order to facilitate the manufacturing and assembly of the water filling seat, as shown in fig. 5 and 6, a rectangular water filling through hole 22 may be formed in a left side wall of the box door, the water filling seat includes a rectangular fixing box body 51, a left side of the fixing box body is opened to form a drawing opening 511 matching with the water filling through hole, lugs 514 are respectively formed on an upper side and a lower side of the fixing box body, the fixing box body is fixed on a surface layer on one side of the box door by screws on the lugs, and at this time, the drawing opening of the fixing box body is connected with the water filling through hole. In addition, a water injection pipe is connected to a lower portion of the right side of the fixed case opposite to the drawing opening, a rectangular parallelepiped drawing case 52 is slidably connected to the drawing opening, and an upper portion of the drawing case is opened.

When water is injected into the water tank, the drawing box body can be pulled out to the left side, at the moment, a user can inject water into an upper opening of the drawing box body by using tools such as a kettle and the like, water entering the drawing box body enters the fixed box body, and then flows into the water tank through a water injection pipeline on the other side of the fixed box body. When the water injection is finished, the user only needs to push the drawing box body back into the fixed box body again to ensure that the side edge of the box door keeps flat and beautiful. That is to say, when not needing the water injection, the pull box body is located the pull opening of fixed box body, therefore can not influence the outward appearance of chamber door, causes the interference when avoiding opening the chamber door, is favorable to keeping the clean health of water injection seat simultaneously. When water needs to be filled, the water tank does not need to be pulled out.

Preferably, the right side wall lower part that the pull box body is close to the water injection pipeline opens and forms apopore 521 to when outwards pulling out the pull box body and toward the internal water injection of pull box, the internal water accessible apopore of pull box gets into in the fixed box body, and the rethread water injection pipeline gets into in the water tank fast, avoids the internal water of pull box to outwards ooze through and the fit clearance between the fixed box body effectively.

Furthermore, we can also set up the location structure that can inject the pull box body and move the stroke between pull box body and fixed box body to accurately inject the outward stroke of pull box body, avoid the excessive pull of pull box body and deviate from the water injection through-hole.

Furthermore, the positioning structure comprises a sliding groove 512 arranged on the top wall of the fixed box body and extending along the left-right direction, and a limiting bump 522 arranged on the upper edge of the side wall of the drawing box body, wherein the limiting bump is connected in the sliding groove in a sliding manner. Through the length of rationally setting up the spout, can accurately inject the removal stroke of pull box body. Of course, the limiting projection should be arranged on the side of the upper edge of the side wall of the drawer box body far away from the drawer opening.

When the water injection seat is assembled, the rear end of the drawing box body with the limiting lug is inclined downwards, then the upper side of the rear end of the drawing box body and the limiting lug are placed into the drawing opening of the fixed box body, the limiting lug is clamped into the sliding groove of the fixed box body, then the front end of the drawing box body rotates downwards to swing the drawing box body, and at the moment, the drawing box body can be pushed into the fixed box body to form the water injection seat.

Or, one side of the sliding groove close to the drawing opening can be opened, so that the drawing box body can be conveniently installed in the fixed box body. When the drawing box body is drawn out, the limit lugs lean against the inner side wall of the box door, and the positioning of the drawing box body can be realized.

It should be noted that we can make the drawing opening of the drawing box body and the fixed box body have enough fit clearance in the height direction, so as to facilitate the rear end of the drawing box body to enter the drawing opening of the fixed box body.

In order to conveniently draw the drawing box body out of the fixed box body, the drawing box body can be exposed out of the upper portion of the outer side wall of the water injection through hole and obliquely arranged outwards, so that the upper portion of the outer side wall of the drawing box body is higher than the outer side face of the box door, and a fastening position 53 suitable for a user finger to enter is formed between the outer side wall of the drawing box body and the side wall of the box door. When water is injected into the water tank, a user only needs to stretch fingers into the hand buckling position, the drawing box body can be conveniently moved outwards, and therefore water can be conveniently added into the water tank.

As an alternative, as shown in fig. 7, the side wall of the box door on the upper side of the water filling through hole is concavely arranged in an inward arc shape, that is, the outer side wall of the box door on the upper portion of the drawer box body is lower than the vertical outer side wall of the drawer box body, so that a hand fastening position suitable for a user's finger to enter is formed between the outer side wall of the drawer box body and the inwardly sunken side wall of the box door.

When water is injected into the water tank, a user only needs to stretch fingers into the hand buckling position, the drawing box body can be conveniently moved outwards, and therefore water can be conveniently added into the water tank. Because the outer side wall of the drawing box body is generally kept flush with the outer side surface of the box body, the interference generated when the box door is opened and closed can be effectively avoided, the appearance of the box door is favorably improved, and external dust is not easy to enter the drawing box body.

In order to avoid water from leaking out through the fit gap between the fixed box and the drawing box when water is injected into the water injection seat, as shown in fig. 8, an upward protruding water blocking rib 513 may be disposed at the lower edge of the drawing opening, and a downward protruding water blocking rib may be disposed at the lower edge of the sidewall of the drawing box close to the water injection pipeline. On one hand, the drawing box body can be stably positioned in the fixed box body and is in sliding connection with the fixed box body. On the other hand, when the user pours water into the pull box body, most water enters the fixed box body through the water outlet hole of the pull box body, and then enters the water tank through the water injection pipeline, and trace water seeps into the fit clearance between the pull box body and the fixed box body, and under the action of self gravity, the part of water can gather on the lower side wall of the fixed box body, and flows towards the pull opening, and flows inwards after being blocked by the water retaining ribs at the pull opening, and flows into the water tank through the water injection pipeline in the fixed box body.

Furthermore, the top wall and the bottom wall of the fixed box body can be inclined downwards from outside to inside, namely, the lower side wall of the fixed box body is an inclined plane with a higher outside and a lower inside. Therefore, a small amount of water seeping into the fit clearance between the drawing box body and the fixed box body can automatically flow into the water injection pipeline along the lower side wall of the inclined fixed box body, and the water seeping into the fit clearance between the drawing box body and the fixed box body can be effectively prevented from flowing out from the drawing opening. Of course, the bottom wall and the top wall of the pull-out cassette are also arranged obliquely and the inclination of the bottom wall is matched with that of the bottom wall of the fixed cassette, so that the pull-out cassette in the fixed cassette can be conveniently pulled out.

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.
