Disclosure of Invention

In view of the above, an object of the present invention is to provide a dish washing machine that can suppress contact of hot air with the hands and arms of a user when the washing tub is pulled out.

In order to solve the above problems, a dish washing machine according to the present invention includes: a housing having a front surface opened; a washing tub which is housed in the housing so as to be pulled out toward the front Fang Ziru, is capable of housing tableware, and has an upper surface that is open; and a front door which is mounted in front of the washing tank and covers the front surface opening of the housing when the washing tank is accommodated in the housing, a handle part for hanging fingers when the washing tank is pulled out forward is formed on the upper front surface of the front door protruding upward than the upper surface of the washing tank, characterized in that a part of the upper part of the front door including the handle part in a prescribed lateral range is set as an upper part 1, a part deviating from the upper part 1 to the lateral direction is set as an upper part 2, the upper surface rear edge of the upper part 2 is located at a position forward than the upper surface rear edge of the upper part 1, and the rear surface of the upper part 2 forms an inclined surface inclined downward toward the rear from the upper surface rear edge of the upper part 2.

Here, when the dish washing machine is disposed below the kitchen counter top of the combination kitchen, when the washing tub is pulled out, the upper surface rear edge of the upper portion of the front door is displaced to a position forward of the front edge of the kitchen counter top, and then the hot air in the washing tub is blown out. In the present invention, when the washing tub is pulled out, the upper surface rear edge of the upper part 2 of the upper part of the front door is displaced earlier than the upper surface rear edge of the upper part 1 to a position more forward than the front edge of the kitchen counter. Therefore, the hot air in the cleaning tank is blown out from the upper portion 1 to the upper portion 2 laterally offset from the upper portion where the handle portion is located. In the present invention, since the rear surface of the upper portion 2 is formed as an inclined surface having a high front and a low rear, the hot air is blown out with a component in the forward direction from the upper portion 2 side. As a result, contact between the hot air and the hand or arm of the user who is engaged with the handle portion by the fingers can be suppressed.

In the present invention, it is preferable that the upper surface trailing edge of the upper portion 2 near the end of the upper portion 1 is formed as an inclined edge inclined obliquely forward from the upper surface trailing edge of the upper portion 1 toward the upper surface trailing edge of the upper portion 2 other than the end, and a step surface which is inclined downward toward the inclined surface of the rear surface of the upper portion 2 from the inclined edge and is formed at the end along a surface parallel to the vertical direction including the inclined edge. In this way, the hot air blown out from the upper portion 2 side is given a lateral component in a direction away from the upper portion 1 by the step surface. Therefore, contact between the hot air and the hand or arm of the user who is engaged with the handle portion by the finger can be further effectively suppressed.

When the operation switch is turned on and then the washing tub 2 is stored in the housing 1, water is first supplied to the washing tub 2, and detergent is mixed into the water from a detergent supply mechanism, not shown, to generate washing water. The cleaning pump 4 is rotated forward while heating the cleaning water to 70 ℃ or higher by a heater (not shown) in the cleaning tank 2, and the cleaning operation for jetting the cleaning water from the cleaning nozzle 3 is performed for a predetermined time. After the washing operation is completed, the washing pump 4 is reversed to discharge the washing water in the washing tub 2. Next, after water is supplied again to the washing tub 2, the washing pump 4 is rotated forward, washing operation for jetting washing water from the washing nozzle 3 is performed for a predetermined time, and then the washing pump 4 is rotated backward to drain the water in the washing tub 2. Further, although the flushing operation is performed a predetermined number of times, the heating flushing operation is performed in which water is sprayed while the water is heated to 70 ℃ or higher by the heater in the last time. Next, a drying operation is performed for a predetermined time period, in which the air in the cleaning tank 2 is heated by the heater and the air is sent into the cleaning tank 2 by a drying fan, not shown. In this case, a heater dedicated to the drying operation may be provided in the cleaning tank 2 or in a blast passage connected to the cleaning tank 2 from a drying fan. In addition, a heater for heating the washing water and a heater for heating the air supplied for drying may be separately provided.

The heating of water and air by the heater as described above is to improve the cleaning effect, the sterilizing effect, and the drying effect. The temperature in the washing tub 2 immediately after the operation of the dish washing machine is stopped is brought to a high temperature of 70 ℃ or higher by the heating. When the washing tub 2 is pulled out during and immediately after the operation of the dish washing machine is stopped, the rear edge of the upper surface of the upper portion 71 of the front door 7 is displaced to a position forward of the front edge of the kitchen counter CT, and then the hot air in the washing tub 2 is blown out. If the hot air contacts the hand or arm of the user who is engaged with the grip 72 by the fingers, a feeling of discomfort is generated.

Therefore, in the present embodiment, the shape of the upper portion 71 of the front door 7 is carefully designed so that contact of the hot air with the user's hand and arm can be suppressed. The shape of the upper portion 71 is described as follows: the part of the upper part 71 including the prescribed lateral range of the handle part 72, i.e., the prescribed lateral range of the lateral center part is set as the upper part 1 st part 71 ₁ Will be from the upper 1 st part 71 ₁ Laterally offset, i.e. at the upper 1 st part 71 ₁ Is set as an upper 2 nd portion 71 ₂ 。

Referring also to FIG. 3, upper 2 nd portion 71 ₂ Upper surface trailing edge 71 of (a) ₂ a is located in the upper 1 st part 71 ₁ Upper surface trailing edge 71 of (a) ₁ a is located further forward. In addition, an upper 2 nd portion 71 ₂ Is formed from the rear surface of the 2 nd portion 71 from above ₂ Upper surface trailing edge 71 of (a) ₂ an inclined surface 71 inclined downward toward the rear ₂ b. Further, upper 1 st portion 71 ₁ The rear surface of (a) is a surface almost along the up-down direction.

According to the present embodiment, as shown in FIG. 4When the cleaning tank 2 is pulled out, the upper 2 nd portion 71 of the upper portion 71 of the front door 7 ₂ Upper surface trailing edge 71 of (a) ₂ a ratio upper 1 st part 71 ₁ Upper surface trailing edge 71 of (a) ₁ a is first displaced to a position further forward than the leading edge of the kitchen counter CT. Therefore, the hot air in the cleaning tank 2 is discharged from the upper 1 st portion 71 where the handle portion 72 is located ₁ Laterally offset upper 2 nd portion 71 ₂ And blowing out laterally and externally. Here, if the upper 2 nd portion 71 ₂ If the rear surface of the handle 72 is a surface along the vertical direction, the hot air is blown upward along the rear surface, and the blown hot air may detour in the lateral direction and come into contact with the hands and arms of the user who is engaged with the handle 72. In contrast, in the present embodiment, the upper 2 nd portion 71 ₂ Is formed into an inclined surface 71 with a front high and a rear low ₂ b, therefore, the hot gas has a 2 nd portion 71 from above as indicated by the arrow in FIG. 4 ₂ Side-blown in a forward direction. As a result, the hot air can be prevented from coming into contact with the hand and arm of the user who is engaged with the grip 72.

In the present embodiment, the upper 2 nd portion 71 ₂ Is adjacent to the upper 1 st portion 71 ₁ The upper surface trailing edge of the end of (2) is formed as: from the upper part 1 st part 71 ₁ Upper surface trailing edge 71 of (a) ₁ a towards the upper 2 nd portion 71 beyond the end ₂ Upper surface trailing edge 71 of (a) ₂ a inclined edge 71 inclined obliquely forward ₂ c. Further, an upper 2 nd portion 71 ₂ Is adjacent to the upper 1 st portion 71 ₁ Is formed with a step surface 71 at the end ₂ d, the step surface 71 ₂ d from the inclined edge 71 ₂ c toward the upper 2 nd portion 71 ₂ Inclined surface 71 of the rear surface of (a) ₂ b descend downward and along a slope 71 ₂ c is a plane parallel to the vertical direction. Thus, due to the step surface 71 ₂ d to the 2 nd part 71 from above ₂ The hot air blown out from the side is given away from the upper 1 st part 71 ₁ Transverse component of the direction of (c). Therefore, contact between the hot air and the hand or arm of the user who is engaged with the grip 72 by the fingers can be further effectively suppressed.

In addition, in the case of the optical fiber,when the cleaning tank 2 is pulled out, the locking piece 721 is first operated to release the lock, so that the cleaning tank 2 protrudes forward by a predetermined stroke as described above. The prescribed stroke is set as follows: only the upper 2 nd part 71 ₂ Upper surface trailing edge 71 of (a) ₂ a is located further forward than the leading edge of the countertop CT. Therefore, at the time of unlocking, the hot air in the cleaning tank 2 flows from the upper 2 nd portion 71 ₂ And blowing out laterally and externally. Thus, even if the upper 1 st portion 71 is caused by the pulling-out operation of the cleaning tank 2 after the lock release ₁ Upper surface trailing edge 71 of (a) ₁ a to a position forward of the leading edge of the kitchen counter CT, the hot air will not flow from the upper 1 st part 71 ₁ Side blowing.

The embodiments of the present invention have been described above with reference to the drawings, but the present invention is not limited thereto. For example, in the above embodiment, the handle portion 72 is provided at the lateral center portion of the upper portion 71 of the front door 7, but the handle portion 72 may be provided at a portion of the upper portion 71 of the front door 7 on the lateral side. However, according to the above embodiment, since the hot air blown out when the cleaning tank 2 is pulled out is dispersed to the left and right sides, even when fingers of either one of the left and right hands are caught by the handle portion 72, there is no deviation in effect, and an advantageous embodiment is constituted. In the above embodiment, the upper surface front edge of the upper portion 71 of the front door 7 is formed from the 1 st portion 71 ₁ To the upper part 2 nd part 71 ₂ The upper surface front edge of the upper portion 71 is formed in a straight line shape which is uniform in the front-rear direction, but may be formed in a shape which is not uniform in the front-rear direction, such as a curved line which is curved in the front-rear direction.
